We bring together two emerging technologies that show great potential for realizing highly-efficient concrete structures: topology optimization for simulation-driven design and 3D concrete printing (3DCP) for manufacturing of optimized shapes. While this is not the first-ever 3D-printed concrete structure, it is the first demonstration of how topological design in combination with 3D concrete extrusion printing allows for creating efficient structures with reduced use of materials. As the implementation of a specific optimization procedure for post-tensioned concrete structures is so far available in 2D only, some design post-processing was necessary, and a 3D finite element analysis was performed. After realization of the 3DCP element (i.e. printing and assembly), the girder's structural performance was experimentally verified using digital image correlation. The deflection of the girder was compared with the numerical results. The manuscript includes thorough discussions on the manufacturing challenges – including printing setup, assembly and integration of reinforcement. © 2020 Elsevier B.V.","3D concrete printing; Bridge design; Prestressed concrete; Topology optimization","Bridges; Concrete beams and girders; Concrete buildings; Concrete construction; Design; Prestressed concrete; Shape optimization; Structural optimization; Tensile strength; Topology; 3D-finite element analysis; Bridge design; Concrete printings; Digital design and manufacturing; Digital image correlations; Manufacturing challenges; Post-tensioned concrete girders; Simulation-driven designs; 3D printers",,,,,"Universiteit Gent; Technion-Israel Institute of Technology","This research project was supported by Ghent University , Vertico , and Technion - Israel Institute of Technology .

This paper focuses on presenting the closed-form solutions of the forced transverse vibration of a coupled Timoshenko double-beam system under compressive axial load. The solutions are generalized and can be suitable for any boundary conditions. The present model is generalized and can be reduced to any existing double-beam systems. Timoshenko model is employed to express the two beams of the double-beam system. Using the Laplace transform, the steady-state Green's functions of the coupled double-beam system can be derived. Since the Green's functions are fundamental solutions of the system, the steady-state forced vibration solutions can be obtained with the help of the superposition principle. In the numerical section, the present solutions are compared with the other known results along with FEM solutions for verification. In addition to the influences of the stiffness modulus of Winkler elastic layer and axial force on the present solutions that should be discussed, the influences of some physical parameters, such as the height-to-length ratio, external frequency, shearing effect, rotational inertia, on the closed-form solutions will also be presented. The effect of the compressive axial load is studied in this work. © 2019 Elsevier Ltd","Axial load; Double-beam systems; Forced vibrations; Green's functions; Winkler elastic layer","Axial loads; Bridges; Green's function; Hydroelasticity; Laplace transforms; Closed form solutions; Compressive axial load; Double-beam system; Forced vibration; Practical engineering applications; Superposition principle; Transverse vibrations; Winkler elastic layers; Vibration analysis",,,,,"Shljzyh2017-007; 2019JDTD0017; 2018CXTD07; National Natural Science Foundation of China, NSFC: 11372257, 11472064, 11602208, 11702230, 11772100, 11872319, 2016YFC0802305, 51674216","The work was supported by the National Natural Science Foundation of China (Nos. 11702230 , 11372257 , 11602208 , 11772100 , 51674216 , 11472064 and 11872319 ) and Program for the risk assessments and control of the coastal pipe and its terrestrial terminal (No. 2016YFC0802305 ) and for Sichuan youth scientific and technological innovation research team of engineering structural safety assessment and disaster prevention technology ( 2019JDTD0017 ).

First-principles approaches such as density functional theory (DFT) provide the best possible accuracy on electronic properties but they are limited to systems up to a few hundreds, or at most thousands of atoms. On the other hand, classical molecular dynamics (CMD) simulations and the finite element method (FEM) are extensively employed to study larger and more realistic systems, but conversely depend on empirical information. Here, we show that machine-learning interatomic potentials (MLIPs) trained over short ab initio molecular dynamics trajectories enable first-principles multiscale modeling, in which DFT simulations can be hierarchically bridged to efficiently simulate macroscopic structures. As a case study, we analyze the lattice thermal conductivity of coplanar graphene/borophene heterostructures, recently synthesized experimentally (Sci. Adv., 2019, 5, eaax6444), for which no viable classical modeling alternative is presently available. Our MLIP-based approach can efficiently predict the lattice thermal conductivity of graphene and borophene pristine phases, the thermal conductance of complex graphene/borophene interfaces and subsequently enable the study of effective thermal transport along the heterostructures at continuum level. This work highlights that MLIPs can be effectively and conveniently employed to enable first-principles multiscale modeling via hierarchical employment of DFT/CMD/FEM simulations, thus expanding the capability for computational design of novel nanostructures. © 2020 The Royal Society of Chemistry.",,"Computation theory; Crystal lattices; Density functional theory; Design for testability; Electronic properties; Graphene; Machine learning; Materials properties; Molecular dynamics; Ab initio molecular dynamics; Classical molecular dynamics; Computational design; First-principles approaches; Interatomic potential; Lattice thermal conductivity; Macroscopic structure; Multi-scale Modeling; Thermal conductivity",,,,,"Deutsche Forschungsgemeinschaft, DFG: 390833453, EXC 2122; Ministerio de Economía y Competitividad, MINECO: SEV-2017-0706; Russian Science Foundation, RSF: 18-13-00479","B.

More abundant physical phenomena are given by modal analysis, shows that the band gap of three-dimensional acoustic black hole metamaterial is different from two-dimensional one. Lateral flexural vibrations occurs and make the original first two-dimensional band gap be compressed, and the opening of first three-dimensional band gap are caused by coupling effect between the longitudinal and lateral flexural vibrations. Below 1200Hz, only two band gaps exist, the geometric parameter m1 and angle $\gamma $ could affect the band structure a lot, while the effect of geometric parameter m0 is a little less. Mutual validation of transmission spectra of vibration test and finite element analysis calculation and band gaps, illustrating its validity of the structure design, corresponding results could stimulate the realizations of three-dimensional acoustic black hole structure, particularly paves the way for the bridge from the corresponding theory of low frequency vibration and noise reduction to the practical application. © 2013 IEEE.","Acoustic black hole; band gap; metamaterial beam; vibration test","Bridges; Elastic waves; Energy gap; Gravitation; Metamaterials; Modal analysis; Noise abatement; Stars; Acoustic black holes; Flexural vibrations; Low-frequency vibration; Physical phenomena; Structure design; Transmission spectrums; Vibration test; Wave attenuation; Vibration analysis",,,,,"National Natural Science Foundation of China, NSFC: 11704314; China Postdoctoral Science Foundation: 2018M631194","This work was supported in part by the National Natural Science Foundation of China (NSFC) under Grant 11704314, and in part by the China Postdoctoral Science Foundation Funded Project under Grant 2018M631194.",,,,,,,,,,"Ma, F., Chen, J., Wu, J.H., Three-dimensional acoustic sub-diffraction focusing by coiled metamaterials with strong absorption (2019) J.

The damages in the pier initiate with appearing of local shear failures in the slender columns during the ship collision stage and reach the severe cross-sectional fractures associated with the formation of plastic hinges which causes the combined shear-flexural failures during the free vibration phase of the pier response. In addition, an analytical simplified model with two-degree-of-freedom (2-DOF) is proposed to formulate the strain rate effects of the concrete materials as the dynamic increase factors in the global responses of the impacted pier. It is found that the analytical model is able to efficiently estimate the impact responses of the structure compared to those from the FE high-resolution simulations. Moreover, three different damage indices are proposed based on the pier deflection, the internal energy absorbed by the pier, and the axial load capacity of the pier columns to classify the damage levels of the pier. Finally, an efficient damage index method is determinant by comparing the calculated results with the damage behaviors of the pier observed from the FE simulations. © 2019 Elsevier Ltd","Cable-stayed bridge pier; Damage index; Progressive damage; Ship collision; Strain rate effects","Bridge piers; Cable stayed bridges; Cables; Degrees of freedom (mechanics); Piers; Ships; Strain rate; Damage index; Finite element simulations; High resolution simulations; Nonlinear numerical analysis; Progressive damage; Ship collision; Strain rate effect; Two degreeof-freedom (2-DOF); Damage detection; bridge; cable; collision; damage mechanics; finite element method; maritime transportation; nonlinearity; strain rate; support structure; vibration",,,,,"2017YFC0703603; Department of Education of Shandong Province; National Natural Science Foundation of China, NSFC: 51678322","The research is financially supported by the Ministry of Science and Technology of China (Grant No. 2017YFC0703603 ), the National Natural Science Foundation of China (Grant No. 51678322 ), the Taishan Scholar Priority Discipline Talent Group program funded by the Shandong Province , and the first-class discipline project funded by the Education Department of Shandong Province .",,,,,,,,,,"AASHTO, Guide specifications and commentary for vessel collision design of highway bridges (2009), second ed.

To compensate the positioning error of coarse stage and achieve a large motion stroke, a symmetrical structure with an arch-shape bridge-type amplifier based on single notch circular flexure hinges is proposed and utilized in the positioning stage. Due to the compound bridge arm configuration and compact flexure hinge structure, the amplification mechanism can realize high lateral stiffness and compact structure simultaneously, which is of great importance to protect PZT actuators. The amplification mechanism is integrated into the decoupling mechanism to improve compactness, and to produce decoupled motion in X- and Y-axes. An analytical model is established to explore the static and dynamic characteristics, and the geometric parameters are optimized. The performance of the positioning stage is evaluated through finite element analysis and experimental test. The results indicate that the stage can implement 2-DOF decoupled motion with a travel range of 55.4 × 53.2 μm2, and the motion resolution is 8 nm. The stage can be used in probe tip-based micro/nano scratching. © 1982-2012 IEEE.","Actuator-internal configuration; arch-shape bridge-type amplifier (ASBTA); decoupling mechanism; micro/nano positioning","Actuators; Analytical models; Bridges; Degrees of freedom (mechanics); Dynamics; Fasteners; Hinges; Kinematics; Piezoelectric actuators; Structure (composition); Amplification mechanism; Bridge-type; Decoupling mechanism; Force; Micro/nano positioning; Static and dynamic characteristics; Symmetrical structure; Two degreeof-freedom (2-DOF); Arches",,,,,"2017YFE0112100, 734174; 2016YFE0112100, 644971; National Natural Science Foundation of China, NSFC: 51675367, 51675371, 51675376; National Key Research and Development Program of China, NKRDPC: 2017YFB1104700","Manuscript received June 10, 2018; revised September 21, 2018, October 29, 2018, and November 22, 2018; accepted November 22, 2018.

In this context, nonlinear component modeling criteria are typically based on ASCE 41 guidelines. Experiments on wide-flange steel columns suggest that the ASCE 41-13 nonlinear component models do not adequately reflect the expected steel column behavior under cyclic loading. To help bridge the gap between state-of-the-art research and engineering practice, this paper proposes new modeling criteria for the first-cycle envelope and monotonic backbone curves of steel wide-flange columns for use in nonlinear static and dynamic frame analyses. The proposed nonlinear provisions include new parameters for concentrated hinge models to facilitate modeling of strength and stiffness deterioration of steel columns under seismic loading. The associated variability in the model parameters is also quantified to facilitate reliability analyses and development of probabilistic acceptance criteria for design. Recommendations are made to account for the influence of bidirectional lateral loading and varying axial load demands on the steel column's hysteretic behavior. Also proposed is an increase in the compression axial force limit for characterizing columns as force-controlled versus deformation-controlled in line with the new ASCE 41 provisions. The proposed modeling parameters are validated against test data and continuum finite-element analyses, and they are proposed for consideration in future updates to ASCE 41 requirements for nonlinear static and dynamic analyses of steel frame buildings with wide-flange columns. © 2019 American Society of Civil Engineers.","ASCE 41; Cyclic deterioration; Model uncertainty; Nonlinear component modeling; Performance-based seismic engineering; Steel frame buildings; Steel wide-flange columns","Bridges; Deterioration; Earthquake engineering; Flanges; Hysteresis; Seismology; Steel construction; Stiffness; Structural design; Structural frames; ASCE 41; Cyclic deterioration; Flange columns; Model uncertainties; Nonlinear components; Performance Based Seismic Engineering; Steel frame buildings; Uncertainty analysis",,,,,"National Institute of Standards and Technology, NIST: 1140-22-431; Schweizerischer Nationalfonds zur Förderung der Wissenschaftlichen Forschung, SNF: 200021_169248","The research forming the basis for this publication was conducted pursuant to a contract with the National Institute of Standards and Technology (Contract No. 1140-22-431).

To build accurate 3D models it is first necessary to perform a geomatics survey. This means performing a survey with active or passive sensors and, subsequently, accomplishing adequate post-processing of the data. In this way, it is possible to obtain a 3D point cloud of the structure under investigation. The next step, known as ""scan-to-BIM (building information modelling)"", has led to the creation of an appropriate methodology that involved the use of Rhinoceros software and a few tools developed within this environment. Once the 3D model is obtained, the last step is the implementation of the structure in FEM (finite element method) and/or in HBIM software. In this paper, two case studies involving structures belonging to the cultural heritage (CH) environment are analysed: a historical church and a masonry bridge. In particular, for both case studies, the different phases were described involving the construction of the point cloud and, subsequently, the construction of a 3D model. This model is suitable both for structural analysis and for the parameterization of rheological and geometric information of each single element of the structure. © 2020 by the authors.","FEM; HBIM; Point cloud; Rhinoceros; Scan-to-BIM",,,,,,"407-27/02/2018 AIM","This research was conducted with funds from the DICATECh of the Polytechnic of Bari (Italy).

A novel fault detection scheme is proposed to build a bridge between AI and real-world running mechanical systems. First, the finite element method simulation is used to simulate samples with different faults to overcome the shortcoming of missing fault samples. Second, to enlarge datasets, new samples similar to the simulation and measurement fault samples are generated by generative adversarial networks and further combined with the original simulation and measurement samples to obtain synthetic samples. Finally, the synthetic and unknown fault samples are severed as the training and test samples, respectively, to the classifiers of AI models, and the unknown fault types will be finally determined. A public datasets of bearings have been used to verify the effectiveness of the proposed scheme. It is expected that the proposed scheme can be extended to complex mechanical systems. © 2005-2012 IEEE.","Bearings; detection; fault samples; finite element method (FEM); generative adversarial networks","Bearings (machine parts); Bearings (structural); Error detection; Fault detection; Mechanics; Adversarial networks; Artificial intelligent; Complex mechanical system; Fault detection schemes; Fault sample; Finite element method simulation; Mechanical systems; Simulations and measurements; Finite element method",,,,,"ZD2019042, ZG2019018; 2018R52034; National Natural Science Foundation of China, NSFC: U1709208, U1909217","Manuscript received December 23, 2019; accepted January 15, 2020.

Impact performances of UHPFRC columns were first examined by using the drop-hammer impact test system. The impact-resistant performance of an axially-loaded UHPFRC column was experimentally confirmed to be superior to that of the conventional RC column. The importance of exerting an axial load was highlighted and addressed by comparing the experimental data of UHPFRC columns with and without axial loads. Subsequently, three different types of UHPFRC-strengthened RC columns were experimentally investigated in detail. Superior performances were observed for the strengthened column with two-end (i.e., potential plastic hinge zone) UHPFRC jackets in comparisons with the other strengthening schemes. Impact strengths could be improved when adding a UHPFRC jacket in the contact zone, but significant increases in impact forces would be induced simultaneously. The column with UHPFRC jackets in both the contact zone and the two ends was shown to be the worst configuration because shear (or punching) failure is prone to occur in the remaining RC portions. A finite element (FE) modeling method was proposed and demonstrated as being capable of reasonably predicting impact responses of UHPFRC columns and UHPFRC-strengthened columns. The findings drawn from the experimental and numerical studies can facilitate the strategic application of UHPFRC for improving the impact-resistant performance of bridge and building columns. © 2019 Elsevier Ltd","Drop-hammer impact test; High-resolution finite element (FE) model; UHPFRC-strengthened column; Ultra-high performance fiber reinforced concrete (UHPFRC)","Axial loads; Drops; Fiber reinforced materials; Finite element method; Hammers; High performance concrete; Impact strength; Drop hammers; Experimental and numerical studies; High resolution; Impact performance; Impact response; Plastic hinge zones; Strengthening methods; Ultra-high-performance fiber-reinforced concrete; Reinforced concrete; column; experimental study; finite element method; loading; numerical model; performance assessment; reinforced concrete",,,,,"2017SK1010; National Natural Science Foundation of China, NSFC: 51308202; National Basic Research Program of China (973 Program): 2018YFC0705405","This research is supported by the National Key Research and Development Program of China (Grant Number: 2018YFC0705405 ), the Major Program of Science and Technology of Hunan Province (Grant Number: 2017SK1010 ), and the National Natural Science Foundation of China (Grant Number: 51308202 ).",,,,,,,,,,"Sha, Y., Hao, H., Laboratory tests and numerical simulations of barge impact on circular reinforced concrete piers (2013) Eng Struct, 46, pp. 593-605; Liu, B., Fan, W., Guo, W., Chen, B.S., Liu, R., Experimental investigation and improved FE modeling of axially-loaded circular RC columns under lateral impact loading (2017) Eng Struct, 152, pp. 619-642; Davidson, M., Consolazio, G., Getter, D., Shah, F., Probability of collapse expression for bridges subject to barge collision (2012) J Bridge Eng, 18, pp. 287-296; Do, T.V., Pham, T.M., Hao, H., Dynamic responses and failure modes of bridge columns under vehicle collision (2018) Eng Struct, 156, pp. 243-259; Harik, I., Shaaban, A., Gesund, H., Valli, G., Wang, S., United States bridge failures, 1951–1988 (1990) J Perform Constr Facil, 4, pp. 272-277; Wardhana, K., Hadipriono, F.C., Analysis of recent bridge failures in the United States (2003) J Perform Constr Facil, 17, pp. 144-150; Buth, C.E., Williams, W.F., Brackin, M.S., Lord, D., Geedipally, S.R., Abu-Odeh, A.Y., Analysis of large truck collisions with bridge piers: phase 1, report of guidelines for designing bridge piers and abutments for vehicle collisions (2010), Texas A & M University System, College Station, Texas Transportation Institute Texas; Sha, Y., Hao, H., Laboratory tests and numerical simulations of CFRP strengthened RC pier subjected to barge impact load (2015) Int J Struct Stab Dyn, 15, p. 1450037; Liu, G., Behavior of bridge piers during vehicular impacts (2012), The City University of New York New York, USA; (2009), AASHTO.

The dynamic analyses are performed using a software named VSI - Vehicle-Structure Interaction Analysis developed by the first authors. The wind load is applied to the bridge and train using a practical methodology based on a discrete gust model, thus avoiding the generation of complex stochastic wind models. The dynamic response of both the bridge and train is assessed and the running safety criteria evaluated. Two different bridge structural solutions have been proposed by the designer. Therefore, the results obtained on these two structural solutions are compared and the limit values for the train speed for each analyzed wind speed are defined based on the running safety criteria allowances defined in the codes. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.","crosswinds; discrete gust wind model; dynamic analysis; finite element models; high-speed railways; Train running safety; train-bridge interaction","Dynamic analysis; Finite element method; Railroad bridges; Railroad cars; Railroads; Speed; Stochastic models; Stochastic systems; Wind; crosswinds; High - speed railways; Train running safety; Train-bridge interaction; Wind modeling; Railroad transportation",,,,,,,,,,,,,,,,"Andersson, E., Häggström, J., Sima, M., Stichel, S., Assessment of train-overturning risk due to strong cross-winds (2004) Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 218 (3), pp. 213-223; (2018) Canonsburg, , PA, USA: Academic Research, Release 19.2, ANSYS Inc; Antolín, P., (2013) Efectos dinámicos laterales en vehículos y puentes ferroviarios sometidos a la acción de vientos transversales.

For this purpose, a nonlinear finite element analysis of circular concrete-filled steel tube columns with ultra-high-strength concrete was conducted and verified with experiments in the literature. Accordingly, a database of 768 finite element models was generated to use for developing the artificial neural network models. In this regard, the column length, the diameter of steel tube, the thickness of steel tube, yield and ultimate strength of steel tube, and compressive strength of concrete were considered as the input variables while the axial compression capacity was considered as an output variable. The performance of the proposed artificial neural network model was compared with the current structural design codes including AS/NZS 5100.6, Eurocode 4, AISC, and GB 50936. The comparative study indicated that the proposed artificial neural network model achieved a superior prediction compared to others. Ultimately, a graphical user interface tool was developed based on the proposed artificial neural network model to predict the axial compression capacity of circular concrete-filled steel tube columns with ultra-high-strength concrete for practical engineering design. © 2020 Elsevier Ltd","Artificial neural network; axial Compression capacity; Circular concrete-filled steel tube; Graphical user interface; Ultra-high-strength concrete","Axial compression; Bridge decks; Columns (structural); Compressive strength; Finite element method; Forecasting; Graphical user interfaces; High performance concrete; Neural networks; Structural design; Tubes (components); Artificial neural network modeling; Artificial neural network models; Compression capacity; Compressive strength of concrete; Concrete filled steel tube; Concrete filled steel tube columns; Non-linear finite-element analysis; Ultra high strength concretes; Tubular steel structures",,,,,,,,,,,,,,,,"Han, L.-H., Li, W., Bjorhovde, R., Developments and advanced applications of concrete-filled steel tubular (CFST) structures: Members (2014) J.

This is a multi-span masonry arch bridge located in Central Italy, which suffered the collapse of two of the seven spans due to foundation scour during a severe flood in December 2013. The study has a twofold aim: to evaluate with a numerical model the level of scour which led to the bridge failure in 2013 and the corresponding collapse mechanism, and to assess the sensitivity of the bridge's modal properties (vibration frequencies and mode shapes) to different levels of scour. An accurate nonlinear three-dimensional model of the bridge is developed, whose elastic properties are calibrated to match the results of dynamic identification tests performed via Operational Modal Analysis (OMA) on the remaining portion of the bridge. A numerical simulation of the effects of the scour hole progression is also performed on the full bridge, according to recently proposed techniques. The study results provide useful insights on both the cause of collapse of the bridge and the suitability of OMA for bridge scour monitoring. © 2019 Elsevier Ltd","Abaqus FEM; Bridges; Masonry; Operational modal analysis; Scour","ABAQUS; Arches; Bridges; Failure (mechanical); Floods; Masonry bridges; Masonry construction; Masonry materials; Modal analysis; Numerical models; Scour; Collapse mechanism; Dynamic identification; Elastic properties; Masonry; Masonry arch bridges; Operational modal analysis; Three-dimensional model; Vibration frequency; Arch bridges; arch; bridge; collapse; failure analysis; finite element method; flood damage; masonry; scour; vibration; Italy",,,,,,,,,,,,,,,,"Hoffmans, G.J.C.M., Verheij, H.J., Scour manual (2017), Routledge; Melville, B.W., Coleman, S.E., Bridge scour (2000), Water Resources Publications, LLC; Tubaldi, E., Macorini, L., Izzuddin, B.A., Three-dimensional mesoscale modelling of multi-span masonry arch bridges subjected to scour (2018) Eng Struct, 165, pp. 486-500; Sousa, J.J., Bastos, L., Multi-temporal SAR interferometry reveals acceleration of bridge sinking before collapse (2013) Nat Hazards Earth Syst Sci, 13, pp. 659-667; Gavin, K., Obrien, E.J., (2012), Sustainable Maintenance and Analysis of Rail Transport Infrastructure (SMART rail) Railway bridge safety and condition assessment View project Smart Rail View project;; Maddison, B., Scour failure of bridges (2012) Proc Instit Civil Eng - Foren Eng, 165, pp. 39-52; Page, J., (1993), Masonry arch bridges.

The effects of various parameters including steel yield stress, number of carbon-FRP layer, slenderness ratio of the composite column, and spacing of carbon-FRP strip on the axial load bearing capacities of the tested specimens were studied. Moreover, the axial compression behaviour of the circular CFST columns with carbon-FRP composites was evaluated in terms of axial compression force (N)–longitudinal shortening displacement (δ) curves, axial stiffness, strain response, strength enhancement indexes, and ductility indexes. Subsequently, a nonlinear finite element (FE) analysis modelling concerning the surface contact action of carbon-FRP-strengthened circular CFST columns was established and validated experimentally. The experimental and analytical results indicate that strengthening the circular CFST stub columns using carbon-FRP wraps could improve their axial load bearing capacities and prevent outward local bulges for the thin-walled steel tubes. Only a slight effect was observed when laterally confined carbon-FRP strips were used for the type of slender composite columns. Finally, several simplified empirical formulas for predicting the axial load bearing capacity of the circular CFST column partially wrapped by carbon-FRP are proposed. © 2018","Axial load carrying capacity; Carbon-fibre-reinforced polymer (FRP); Concrete-filled steel tubular (CFST); Empirical formulas; Failure modes; Finite element (FE) modelling","Axial compression; Axial loads; Beams and girders; Bearing capacity; Bridge decks; Carbon fiber reinforced plastics; Carbon fibers; Columns (structural); Concretes; Failure modes; Fiber reinforced plastics; Filled polymers; Finite element method; Reinforced plastics; Reinforcement; Steel fibers; Steel testing; Thin walled structures; Tubular steel structures; Yield stress; Carbon fibre reinforced polymer; Compression properties; Compressive performance; Concrete filled steel tubular columns; Concrete-filled steel tubular; Empirical formulas; Longitudinal shortening; Non-linear finite-element analysis; Failure (mechanical)",,,,,"National Natural Science Foundation of China, NSFC: 51478158; Program for New Century Excellent Talents in University, NCET: NCET-12-0838","This work is supported by the National Natural Science Foundation of China (Project 51478158 ), and the New Century Excellent Talents in University (Project NCET-12-0838 ), which is greatly appreciated.

In order to boost the degree of confidence and robustness of the developed model updating procedure, appropriate computational strategies are proposed at the level of both Sensitivity Analysis (SA) and global optimization. In particular, Latin Hypercube Sampling (LHS) is employed in drawing up both strategies, as a systematic automated way to determine appropriate multi-start sets of initiation points, optimally distributed throughout the parametric domain. The procedure involves a gradient-based method and proposes an interaction algorithm between mechanical FEM solver and numerical computing environment. Moreover, the gradient of the objective function involved in the model updating is analytically derived, instead of by often-used Finite Differences (FD), toward better accuracy and computational efficiency. Comprehensive updating results starting from a first FEM base model are achieved, for the considered case study, and show that the relative eigenfrequency and mode shape estimations are considerably improved, for all the structural modes accounted for within the updating process, with a very good final matching between experimentally extracted and FEM modelled modal properties. © 2018 Elsevier Ltd","Global optimization; Historic centennial Reinforced Concrete (RC) arch bridge; Latin Hypercube Sampling (LHS); Model updating; Sensitivity Analysis (SA); Structural identification","Arches; Computational efficiency; Finite difference method; Geometry; Global optimization; Numerical methods; Reinforced concrete; Computational strategy; Degree of confidence; Gradient-based method; Latin hypercube sampling; Model updating; Numerical computing; Optimization procedures; Structural identification; Sensitivity analysis; accuracy assessment; bridge; computer simulation; concrete structure; efficiency measurement; finite difference method; historic building; numerical model; optimization; sensitivity analysis",,,,,,,,,,,,,,,,"Ribeiro, D., Calçada, R., Delgado, R., Brehm, M., Zabel, V., Finite element model updating of a bowstring-arch railway bridge based on experimental modal parameters (2012) Eng Struct, 40, pp. 413-435; Shabbir, F., Omenzetter, P., Model updating using genetic algorithms with sequential niche technique (2016) Eng Struct, 120, pp. 166-182; Bedon, C., Dilena, M., Ambient vibration testing and structural identification of a cable-stayed bridge (2016) Meccanica, 51, pp. 2777-2796; Reynders, E., System identification methods for (Operational) Modal Analysis: Review and comparison (2012) Arch Comput Methods Eng, 19 (1), pp. 51-124; Friswell, M.I., Mottershead, J.E., (1995), pp. 263-5. , Finite element model updating in structural dynamics.

The DRI is based on the structural characteristics of the bridge and the kinetic energy of the colliding vehicle. A performance-based approach allows the designer or bridge owner to choose a target performance level based on different parameters, such as the criticality of the bridge to the transportation network or economic constraints. Detailed finite element models of the bridge piers were generated, validated, and verified against a series of available experimental and numerical results from previous research. A detailed review of the effects of different design parameters, including the pier diameter and transverse reinforcement ratio, were considered in the response of the bridge piers to collisions. For this purpose, the internal shear forces, bending moments, and displacements under different collision scenarios were studied. The review showed that the pier diameter governs the overall failure mode, the transverse reinforcement ratio controls the amount of localized damage experienced by the pier, and the kinetic energy of the impacting vehicle governs the magnitude of internal forces generated within the pier. This proposed performance-based design approach is based on the novel DRI, which enables straightforward designs of circular reinforced concrete bridge piers for a vehicle collision event without the use of extensive finite element modeling. © 2019","Impact loads; Performance-based; Reinforced concrete piers; Vehicle collision","Bridge piers; Finite element method; Kinetic energy; Kinetics; Reinforced concrete; Impact loads; Performance based; Performance based approach; Performance based design; Reinforced concrete pier; Structural characteristics; Transverse reinforcement ratio; Vehicle collisions; Vehicle performance; bridge; collision; design; loading; performance assessment; reinforced concrete; structural analysis; structural component; transport vehicle",,,,,,,,,,,,,,,,"Wardhana, K., Hadiprione, F.C., Analysis of recent bridge failures in the United States (2003) J Perform Constr Facil, 17, pp. 144-150; Cook, W., (2014), Bridge failure rates, consequences, and predictive trends.

The latter are used to measure the relative displacements of the facing (moving) contact points on the beam, referred to as the scanning points. By adopting proper assumptions, closed-form solutions are derived for the responses of the beam and scanning points. In parallel, the scanning-point response is also given in discrete form for field applications. The road roughness effect is alleviated by using the residual response obtained as the difference of the responses of two consecutive scanning points. By utilizing the attenuation nature in the responses between two separate scanning points due to time lag, the damping ratio of the beam is derived in closed form using the Hilbert transformation. The framework proposed is verified by a finite element analysis with basically no assumptions. Its robustness is also tested for different ranges of parameters, including vehicle speed, vehicle damping, road roughness and environment noise. © 2019 Elsevier Ltd","Bridge; Damping; Hilbert transformation; Moving vehicle; Vehicle scanning method; Vehicle-bridge interaction","Bridges; Damping; Mathematical transformations; Roads and streets; Vehicles; Damping identification; Hilbert transformations; Moving vehicles; Relative displacement; Scanning methods; Simply supported beams; Theoretical framework; Vehicle-bridge interaction; Scanning; bridge; damping; structural component",,,,,"2016YFC0701302; Graduate Scientific Research and Innovation Foundation of Chongqing","This work was supported by the following agencies: Ministry of Science & Technology of China [Grant No. 2016YFC0701302 ] and Graduate Research & Innovation Foundation of Chongqing [Grant No. CYB18034 ].",,,,,,,,,,"McLamore, V.R., Hart, G.C., Stubbs, I.R., Ambient vibration of two suspension bridges (1971) J Struct Div-ASCE, 97 (ST10), pp. 2567-2583; Huang, C.S., Yang, Y.B., Lu, L.Y., Chen, C.H., Dynamic testing and system identification of a multi-span highway bridge (1999) Earthq Eng Struct Dyn, 28 (8), pp. 857-878; Magalhães, F., Cunha, A., Caetano, E., Online automatic identification of the modal parameters of a long span arch bridge (2009) Mech Syst Signal Proces, 23 (2), pp. 316-329; Soyoz, S., Feng, M.Q., Long-term monitoring and identification of bridge structural parameters (2009) Comput-Aided Civ Inf Eng, 24, pp. 82-92; Kim, B.H., Lee, J., Lee, D.H., Extracting modal parameters of high-speed railway bridge using the TDD technique (2010) Mech Syst Signal Proces, 24 (3), pp. 707-720; Melo, L.R.T., Silva, R.S.Y.R.C., Bittencourt, T.N., Bezerra LM.

Because vehicles and bridges create a coupled system, vehicle acceleration data contains information about bridge frequencies that can be used as health indicators. However, for drive-by health monitoring to be viable, variabilities in dynamic measurements caused by environmental and operational parameters, such as temperature, vehicle speed, traffic, and surface roughness need to be considered. In this paper, a finite element model of a simply supported bridge is developed considering the aforementioned variabilities and various levels of structural damage. Vehicle acceleration data obtained from the model is analyzed in the frequency domain and processed using a neural network architecture. This method is used to determine the relationships between noise inducing variables and changes in vehicle dynamic response spectrum; these relationships are leveraged to predict the overall health of the subject bridge. The results from this study indicate that the proposed approach can serve as a viable health monitoring strategy and should be further tested on physical bridge systems.

Traditional approaches investigating the overloading-induced fatigue damage on bridges, such as finite element analysis (FEA)and reliability analysis, have proven to be computationally expensive and model dependent. In this study, the prediction of fatigue failure probability of bridges due to traffic overloading was investigated by using the feedforward neural network and the Monte Carlo method. Our results show that based on a finite set of training data for the bridge under consideration, the proposed machine-learning-based approach can assist in providing an instantaneous assessment of the fatigue failure probability with high accuracy. © 2019","Fatigue damage; Machine learning; Probabilistic analysis; Steel girder bridge; Vehicle overloading","Fatigue damage; Fatigue of materials; Feedforward neural networks; Freight transportation; Learning algorithms; Learning systems; Machine learning; Monte Carlo methods; Reliability analysis; Truck transportation; Bridge failures; Fatigue failure analysis; Fatigue failures; Probabilistic analysis; Probabilistic machines; Steel girder bridge; Traditional approaches; Traffic overloading; Failure (mechanical); artificial neural network; bridge; failure analysis; fatigue; Monte Carlo analysis; probability; road traffic",,,,,"2017SK2224; National Natural Science Foundation of China, NSFC: 51478176, 51778222; China Scholarship Council, CSC: 201706130087","The authors gratefully acknowledge the financial support provided by the National Natural Science Foundation of China (Grant No. 51778222 and 51478176 ), the China Scholarship Council (Grant 201706130087 ), and the Key Research Project of Hunan Province (Grant 2017SK2224 ).",,,,,,,,,,"Bae, H.U., Oliva, M.G., Bridge analysis and evaluation of effects under overload vehicles (No. CFIRE 02–03).

They are characterized by their durability, rigidity, economy and beauty. Concrete bridges have many types such as simply supported girder bridges, arch bridges and rigid frame bridges. However, for very large spans, arch bridges are more economic in addition to their beauty appearance. In this research, a geometrical structural optimization study for a deck concrete arch bridges using Genetic Algorithms technique is presented. This research aims mainly to demonstrate a methodology to find the least cost design, in term of material volume, by finding the optimal profile. A Finite Element numerical model is used to represent the arch structure. The MATLAB programing platform is used to develop codes for Genetic Algorithms optimization technique and Finite Element analysis method. The resulted design from the optimization process is compared to traditional design and an obvious cost reduction is obtained. © 2019 Ain Shams University","Arch bridges; Finite Element; Genetic Algorithms; Optimization","Arch bridges; Arches; Beams and girders; Concrete bridges; Concrete construction; Cost reduction; Finite element method; Genetic algorithms; MATLAB; Optimization; Rigidity; Structural optimization; Arch structures; Concrete arch bridges; Finite element analysis method; Finite element numerical models; Genetic algorithms optimizations; Least-cost design; Rigid-frame bridges; Simply-supported girder bridges; Concretes",,,,,,,,,,,,,,,,"Olivas, F., Ant colony optimization with dynamic parameter adaptation based on interval type-2 fuzzy logic systems (2017) Appl Soft Comput, 53. , Elsevier B.V; Gonzalez, B., Valdez, F., Melin, P., Prado-Arechiga, G., Fuzzy logic in the gravitational search algorithm for the optimization of modular neural networks in pattern recognition (2015), Elsevier Ltd; Holland, J.H., Adaptation in natural and artificial systems (1975), University of Michigan Press Ann Arbor, MI; Sahab, M.G., Ashour, A.F., Toropov, V.V., A hybrid genetic algorithm for reinforced concrete flat slab buildings (2005) Comput Struct, 83; Eid, M.A., (2013), Zaki Abd Elrehim M.

Nine large-scale specimens were tested under static and fatigue loading to explore the failure mode, fatigue life, and failure process. The fatigue test results were compared with the fatigue strength values recommended in different design specifications. Based on the hot spot stress and notch stress approaches, S[sbnd]N curves for rib-to-crossbeam welded joints were derived and compared with the existing fatigue test data.

The confined FGM arch buckles in a single-lobe deformation expressed by an admissible radial displacement function. The critical buckling pressure of the confined FGM arch is obtained analytically by establishing the nonlinear equilibrium equations based on the classical thin-walled arch theory. Subsequently, a two-dimensional (2D) finite element model (FEM) is established to trace the pre- and post-buckling equilibrium paths. Geometric nonlinearities are introduced since large displacement and rotation occur during the whole deformation of the FGM arch. The numerical results show very close agreement with the present analytical solutions in terms of the hoop force through the FGM arch span, the critical buckling pressure, and the pressure-displacement equilibrium paths. Furthermore, the present predictions are compared successfully with other closed-form expressions for the confined homogeneous arch. Finally, the effect of volume fraction exponent on the buckling pressure, the hoop force and bending moment through the arch span is examined and discussed to further understand the buckling behavior of the confined FGM arch. © 2019 Elsevier Ltd","External pressure; FEM; Functionally graded material (FGM); Nonlinear buckling; Stability; Thin-walled rigidly-confined arch","Arches; Beams and girders; Convergence of numerical methods; Deformation; Finite element method; Functionally graded materials; Nonlinear equations; Thin walled structures; Trace elements; Critical buckling pressures; External pressures; Functionally graded material (FGM); Geometric non-linearity; Non-linear equilibrium equation; Nonlinear buckling; Post-buckling equilibriums; Thin-walled; Arch bridges; bending; buckling; displacement; finite element method; pressure effect; stability analysis",,,,,"Iowa State University, ISU","The authors would like to thank the financial support from the Department of Civil, Construction and Environmental Engineering of Iowa State University rewarded to the second author.","The authors would like to thank the financial support from the Department of Civil, Construction and Environmental Engineering of Iowa State University rewarded to the second author.",,,,,,,,,"Uberkritisches, G.D., Verhalten eines Starr Ummantelten Kreisrohres bei Wasserdrunck von Aussen und Temperaturdehnung.

The method is based on the concept of rotation influence line (RIL) at the bridge bearing locations, and solely relies on measurements obtained from two points at either end of the bridge e.g., RIL R and RIL L . The sensitivity of the rotation measurement to damage is first investigated using a 1-D simply supported beam model and it is demonstrated that unlike conventional strain measurements, the rotation measurement is capable of providing useful information about damage even though it is far from the measurement point. Further, an existing cable-stayed bridge is considered to validate the capability of RIL in damage identification. A comprehensive three-dimensional finite element model (FEM) of the bridge is established and calibrated using the measured static and dynamic responses. Numerous field tests are conducted on this large-scale structure to extract static and dynamic characteristics, including natural frequencies, mode shapes and influence lines (ILs). Sixteen hypothetical damage scenarios are induced in the numerical model, including symmetric and asymmetric cases of cable loss. A damage index based on the normalised discrepancy of RIL between the benchmark state and an unknown state is introduced and through extensive investigations it is demonstrated that regardless of damage location, either RIL R or RIL L (or both) can successfully identify the induced damage in all of the sixteen damage scenarios. In contrast, the success of strain-based measurement is highly dependent on the closeness of damage to the sensor location, thus a much higher number of strain gauge sensors is required not to misidentify damage. The contribution of this work is four-fold. First, a novel and robust damage identification technique based on RIL is proposed which has not been reported in the literature. Second, the method solely relies on two measurement points e.g., two tilt meters at either end of the bridge and it is capable of identifying damage, even far from the sensor location. Third, the validation of the technique is demonstrated through extensive numerical and field test investigations on a statically indeterminate cable-stayed bridge structure. Finally, it is demonstrated that the conventional strain-based measurement is very likely to misidentify cable damage even with extreme case of cable loss. © 2019 Elsevier Ltd","Bridge structure; Cable-stayed bridge;

The structural behaviour of these constructions appears often complex to be understood due to the uncertainties related to the materials and internal geometry. In this paper, a complete study (i.e. from the data acquisition and elaboration to the vulnerability analysis and proposal for a non-invasive strengthening procedure) of a monumental bell tower building is reported. An extensive program of structural and geometrical surveys has been planned and performed. The main goal of the breakdown was to assess the stability and the seismic vulnerability of the bell tower. Moreover, an innovative use of the drone-based survey for the computation of the geometry of the structure is proposed, in order to significantly reduce the time-cost expenditure of the structural assessment, without any significant lack in the accuracy of the measurements. The resulting object, obtained from the drone-based digitalized survey, was inputted and set in a Finite Element Method (FEM) code for structural modelling. Moreover, a nonlinear kinematic analysis was performed to individuate the possible failure mechanisms. Finally, a non-invasive strengthening procedure, aiming to the improvement of the seismic capacity, is proposed. © 2019","Bell tower; Diagnosis; Drone; FEM; Masonry; Structural analysis","Bells; Data acquisition; Diagnosis; Drones; Finite element method; Geometry; Masonry materials; Seismology; Structural analysis; Surveys; Towers; Bell towers; Masonry; Nonlinear kinematics; Seismic vulnerability; Structural assessments; Structural modelling; Structural typologies; Vulnerability analysis; Failure (mechanical)",,,,,,"The authors wish to kindly thank to the Italian Ministry of the Cultural Heritage ( MiBAC – Ministrero per I Beni e le Attività Culturali ) and the Superintendency of the municipality of Lecce for the availability and interest shown during the development of this research study.

However, the observation of nonlinear wave loads in shallow waters suggests that second-order wave loads might be essential to the dynamic behavior of marine structures. In this paper, a framework to investigate the stochastic response of a long-span sea-crossing bridge under extreme nonlinear wave loads was proposed based on the combined use of the spectral wave model MIKE21 SW, the 3D diffraction theory hydrodynamic solver AQWA and the structural analysis tool ANSYS. An extreme wave condition of a 300-year return period at the exact bridge site is estimated from offshore statistical wave data by utilizing the state-of-the-art spectral wave model MIKE21 SW by considering of the complex nearshore wave transformation. Linear as well as nonlinear stochastic wave loads are modeled in AQWA and subsequently fed into the finite-element model to assess the responses. The results indicate that the nonlinear wave loads could remarkably increase the dynamic responses of the internal base forces of bridge foundations as well as displacements of superstructures. The sum-frequency second-order components in nonlinear loads, though not large in magnitude, might overlap with the first few eigenfrequencies of the bridge and thus excite these modes and increase the responses. © 2019 Elsevier Ltd","Dynamic responses; Hydrodynamic model; Nonlinear wave loads; Sea-crossing bridge; Wave model","Dynamic response; Hydrodynamics; Metadata; Ocean currents; Offshore oil well production; Offshore structures; Stochastic models; Stochastic systems; Current practices; Hydrodynamic model; Nearshore wave transformations; Nonlinear wave loads; Second order waves; Spectral wave models; Stochastic response; Wave modeling; Structural loads; bridge; dynamic response; extreme event; finite element method; foundation; hydrodynamics; loading; nonlinear wave; stochasticity; wave force; wave modeling; wave-structure interaction",,,,,"National Natural Science Foundation of China, NSFC: 51525804, 51708464; National Basic Research Program of China (973 Program): 2018YFC1507802; Fundamental Research Funds for the Central Universities: 2682019CX02","This work was supported by the National Key Research and Development Program of China (No. 2018YFC1507802 ), the National Natural Science Foundation of China (nos. 51525804 , 51708464 ) and the Fundamental Research Funds for the Central Universities (No. 2682019CX02 ).",,,,,,,,,,"Valeur, J.R., Sediment investigations connected with the building of the Øresund bridge and tunnel (2004) Geografisk Tidsskrift-Danish J Geograp, 104, pp. 1-12; Meisburger, E.P., (1972), Geomorphology and sediments of the Chesapeake Bay Entrance.

Based on field measurements performed for an operational cable-stayed bridge, the proposed study investigates mechanisms of thermally induced variations in girder length and mid-span deflection through plane geometric and finite element analyses. The objective of this study is to understand the behaviour of such bridges over annual and diurnal cycles. It has been observed that the girder length and mid-span deflection of a cable-stayed bridge exhibit different modes of the temperature–response correlation. Thermally induced changes in girder length are solely governed by the average girder temperature, and its annual variation in amplitude is significantly larger compared to the diurnal variation. However, thermally induced mid-span deflections are simultaneously influenced by the cable temperature and average girder temperature, and these do not vary monotonously with temperature, thereby resulting in nearly equal variation amplitudes over both annual and diurnal cycles. Temperature-induced deformations of a cable-stayed bridge could well be approximated through multiple linear superposition of thermal-expansion effects of individual components. Besides thermal-expansion coefficients of structural materials, the temperature dependency of mid-span deflection of a symmetrical twin-tower cable-stayed bridge is closely related to the ratio of tower height above the deck to central span of the girder as well as span ratio of the side span to central span. The proposed simplified formulae to estimate the sensitivities of temperature effects could be readily extended to other cable-stayed bridges with different geometric arrangements, thereby providing valuable insights into thermally induced deformation of such bridges. © The Author(s) 2018.","Cable-stayed bridge; data interpretation; deformation; mechanism; structural health monitoring; temperature effect","Cables; Deflection (structures); Deformation; Mechanisms; Steel beams and girders; Structural health monitoring; Temperature; Thermal effects; Thermal expansion; Data interpretation; Linear superpositions; Structural deformation; Temperature dependencies; Temperature variation; Thermal expansion coefficients; Thermal expansion effect; Thermally induced deformations; Cable stayed bridges",,,,,"National Natural Science Foundation of China, NSFC: 51608034; China Postdoctoral Science Foundation: 2016M600925; Fundamental Research Funds for the Central Universities: FRF-TP-16-012A1","The authors are thankful for the significant assistance received from the Shanghai Yangtze River Bridge Management Co., Ltd. and the Shanghai Just One Technology Development Co., Ltd.

The orthotropic properties of FRPs parallel and perpendicular to the fiber direction lead to a huge challenge in anchoring. In the present paper, a hybrid fiber reinforced polymer (HFRP) composite rod was developed as the bridge stay cable through the pultrusion technology with the diameter of 19 mm, including carbon fiber reinforced polymer core (CFC) and glass fiber reinforced polymer shell (GFS). The simplified mechanical model based on equilibrium, geometric and physical equations and finite element analysis were conducted to analyze the potential failure modes of anchoring HFRP rods. It can be observed that the shear failure of CFC/GFS interface of HFRP anchorage system resulted in a low anchorage bearing capacity. An innovative compound-type anchorage system through the mechanical extrusion and chemical bonding was proposed to provide the reliable anchorage bearing capacity for HFRP rods. It can be found that the stress distribution of compound-type anchorage system was uniform along the anchoring length. The tensile load was effectively transferred to the steel anchor by the extrusion and bonding between HFRP rods and steel wedge. The fatigue life of HFRP rods with the compound-type anchorage system increased 5.88–7.44 times relative to the mechanical anchorage system, and 42.4 times relative to the bonding-type anchorage system. © 2020, RILEM.","Carbon/glass hybrid rod;

The rotation platform is driven by two piezoelectric actuators. Rotation decoupling is realized based on three Hooke's joints, and a large rotation range is obtained based on two bridge-type mechanisms. Compared with other rotation platforms, the developed 2-DOF pure rotation platform has the advantages of fewer actuators due to rotation decoupling design and larger working frequency range due to compact structure and monolithic fabrication. An analytical model is established to calculate transmission ratio and input stiffness. The dominant parameters are determined based on sensitivity analysis. Finite-element analysis is conducted to investigate the characteristics of the rotation platform. Experimental tests are carried out to investigate the performance of the rotation platform. Decoupling test results show that the maximum rotation angles in the X- and Y-axis are 2.04 and 2.12 mrad, respectively, and the X- and Y-axis relative coupling errors are 2.03% and 2.09%, respectively. Closed-loop control results show that the settling time is 40 ms and the resolutions in both X- and Y-axis are 5 μrad. © 2019 IEEE.","Flexure mechanism; monolithic fabrication; rotation decoupling; rotation platform","Degrees of freedom (mechanics); Piezoelectricity; Rotation; Sensitivity analysis; Bridge-type mechanisms; Closed-loop control; Compact structures; Decoupling designs; Micro/nanomanipulation; Monolithic fabrications; Transmission ratios; Two degrees of freedom; Piezoelectric actuators",,,,,"734174; National Natural Science Foundation of China, NSFC: 51675367, 51675371, 51675376; Tianjin Science and Technology Committee: 18PTZWHZ00160, 19PTZWHZ00010; National Key Research and Development Program of China, NKRDPC: 2016YFE0112100, 2017YFB1104700, 2017YFE0112100","Manuscript received June 4, 2018; revised November 28, 2018 and March 28, 2019; accepted July 17, 2019.

However, the method usually requires a substantial amount of time and effort to model concrete and reinforcement and conduct nonlinear contact-impact analyses. Also, the accuracy of the method cannot be guaranteed due to the limitations in concrete material models implemented in general-purpose FE codes. In this paper, an efficient modeling method is proposed to capture both flexural and shear behaviors of RC beams and columns under low-velocity impact loading. A macroelement-based contact model was developed in the proposed method to capture interaction behaviors between impacting objects and RC members. In the contact model, a compression-only spring with an initial gap behavior was used to account for the stiffness and the kinematic response of an impacting object, and a combination of an elastic spring and a viscous damper in parallel was employed to simulate the contact stiffness and damping. By properly approximating the strain-rate effects, traditional fiber-section elements were demonstrated to be capable of predicting impact-induced flexural failures for RC members. On this basis, a general approach for both flexural- and shear-critical RC columns under impact loading was presented with the inclusion of additional shear springs in the fiber-section elements. Nearly fifty impact tests on RC beams and columns reported in the literature were employed to validate the proposed modeling method. Comparisons between the experimental and numerical results indicate that failure modes of the impacted members can be identified explicitly by the use of the proposed modeling method. Also, reasonable agreements were achieved for the impact forces and the impact-induced responses obtained from the impact tests and the analyses. The proposed method can be readily implemented without coding in any FE software as long as traditional fiber-section elements, and discrete macroelements are available. This feature would offer an advantage for the applications of the proposed method such as when assessing the structural response and vulnerability of a bridge structure subjected to vessel and vehicle collisions. © 2019 Elsevier Ltd","Efficient modeling; Fiber-section beam-column elements; Impact responses; Reinforced concrete beams and columns; Shear behaviors","End effectors; Fibers; Numerical methods; Reinforced concrete; Shear flow; Stiffness; Strain rate; Beam column element; Concrete material models; Impact response; Interaction behavior; Low velocity impact; Reinforced concrete beams; Shear behavior; Structural response; Concrete beams and girders; column; compression; damping; finite element method; flexure; impact; induced response; loading; reinforced concrete; shear strain; stiffness",,,,,"2016GK2025, 2017SK1010; National Natural Science Foundation of China, NSFC: 51308202; National Basic Research Program of China (973 Program): 2018YFC0705405","This research is supported by the National Key Research and Development Program of China (Grant Number: 2018YFC0705405 ), the Major Program of Science and Technology of Hunan Province (Grant Number: 2017SK1010 ; 2016GK2025 ), and the National Natural Science Foundation of China (Grant Number: 51308202 ).

It considers the capacitances between the winding and the central limb, side limb, and yoke of the core. The latter two account for a significant proportion of the total capacitance with the increase of the core window utilization factor. The potential of the floating core/shield is derived analytically, which enables the model to apply not only for the grounded core/shield, but also for the floating core/shield cases. On the basis of the improved model, an analytical optimization method for the stray capacitance in inductors is proposed. Moreover, a global Pareto optimization is carried out to identify the tradeoffs between the stray capacitance and ac resistance in the winding design. Finally, the analysis and design are verified by finite element method simulations and experimental results on a 100-kHz dual active bridge converter. © 1986-2012 IEEE.","Core/shield-related capacitance; dual active bridge (DAB) converter; inductor; optimization; stray capacitance","Bridges; Electric inductors; Multiobjective optimization; Optimization; Pareto principle; Winding; Analytical optimizations; Dual active bridge converter; Dual active bridges; Finite element method simulation; inductor; Pareto optimization; Stray capacitances; Utilization factor; Capacitance",,,,,,,,,,,,,,,,"Saket, M.A., Shafiei, N., Ordonez, M., LLC converters with planar transformers: Issues andmitigation (2017) IEEE Trans.

Distinguished from the existed studies, a general concurrent design formulation for the dynamic composite structures with more than two material phases is developed. The macrostructureand its microstructures with multiple material phases are optimized simultaneously. The integral of the dynamic compliances over an interval of frequencies is formulated as the optimization objective, so as to minimize the frequency response within the concerned excitation range. The effective properties of the multiphase microstructures are evaluated by using the numerical homogenization method, which actually serves as a link to bridge the macro and micro finite element analyses. Furthermore, to describe the boundaries of multiple material phases for the microstructure, a parametric color level set method (PCLSM) is developed by using an efficient interpolation scheme. In this way, L level set functions can represent at most 2L material phases without any overlaps. Moreover, these “color” level sets are updated by directly using the well-established gradient-based algorithm, which can greatly facilitate the proposed method to solve the multi-material optimizations with multiple design constraints. Several 2D and 3D numerical examples are used to demonstrate the effectiveness of the proposed method in the concurrent design of the dynamic composite structures under the excitation frequency ranges. © 2019 Elsevier B.V.","Concurrent optimization; Frequency response; Level set method; Multiphase composites; Topology optimization","Drop breakup; Frequency response; Homogenization method; Image segmentation; Level measurement; Microstructure; Shape optimization; Structure (composition); Topology; Gradient based algorithm; Level Set method; Micro-finite element analysis; Multi-material optimizations; Multiphase composites; Multiphase microstructure; Numerical homogenization; Topology Optimization Method; Numerical methods",,,,,"51675196, 51705166, 51825502; Fundamental Research Funds for the Central Universities: 2019kfyXKJC042, 41423010102","This research is partially supported by the National Natural-Science-Foundation of China ( 51705166 , 51825502 and 51675196 ), the Fundamental Research Funds for the Central Universities, China through Program No. 2019kfyXKJC042 , and the China Equipment Pre-research Program, China ( 41423010102 ).",,,,,,,,,,"Gibson, R.F., A review of recent research on mechanics of multifunctional composite materials and structures (2010) Compos.

Algorithms for search for geometric parameters of a composite section limited to a certain range of values are implemented to achieve the equal strength condition. The dimensions of the individual elements which are parts of the cross-section are obtained from the condition of the constant ratio of the distances from the neutral axis to the extreme concrete and steel fibers. The numerical methods were used for calculation of continuous three-span composite reinforce concrete bridge. The technique implements the steps of bridge construction, taking into account the contact yield of the composite section, the redistribution of forces between the elements, and the effect of elastic-plastic and rheological properties of materials. The generalized kinetic curve was utilized for evaluation of concrete creep together with the phenomenological equations for the development of deformations based on a colloid-chemical representation of the mechanism for long-term concrete deformation. The proposed methodology is implemented in the LIRA-SAPR software package based on the Building Information Model Technology (BIM) and the Finite Element Method (FEM). © 2019 Published under licence by IOP Publishing Ltd.",,"Architectural design; Composite structures; Concrete slabs; Deformation; Elastoplasticity; Numerical methods; Railroads; Steel fibers; Bridge constructions; Building Information Model - BIM; Composite sections; Composite steel; Elastic-Plastic; Equal strengths; Phenomenological equations; Rheological property; Reinforced concrete",,,,,,,,,,,,,,,,"(2006) Bridges and Pipes.

In the static load test, the precision spirit leveling technique was used to measure the deflections of the deck induced by four trucks weighing about 36 tonnes each. In the dynamic load test, accelerometers placed on the main beam were used to measure the vibration frequencies following an impulse produced by a 2-tonne truck. The dynamic load test resulted in a refined finite element model of the bridge. The comparison showed that the dynamic load test can supplement the static load test for the structural testing of new bridges or be an alternative to it for the monitoring of operational bridges. © 2019 Elsevier Ltd","Bridge; Dynamic testing; FEM; Finite element model; Load testing; Reinforced concrete; SHM; Structural health monitoring","Automobile testing; Bridges; Dynamic analysis; Dynamic loads; Finite element method; Load testing; Pile driving; Reinforced concrete; Trucks; Dynamic testing; Prestressed reinforced; Static and dynamic load tests; Static load tests; Structural reliability; Structural response; Structural testing; Vibration frequency; Structural health monitoring; bridge; finite element method; health monitoring; loading test; reinforced concrete; testing method; vibration",,,,,,,,,,,,,,,,"(2012), AASHTO (American Association of State and Highway Transportation Officials).

However, considering the geometry and size of the structures, analyzing critical locations can become challenging. Traditional sensors such as strain-gauges are widely used to collect operating data, but these conventional methods cannot present full-field data and only show the measurement data at a few discrete locations. Baqersad and Bharadwaj have recently developed a Strain Expansion-Reduction Approach (SERA) to bridge this gap and to expand a limited set of measurements and obtain full-field strain data. This approach uses the strain mode shapes from Finite Element Analysis (FEA) to develop a transformation matrix that expands the limited strain data measured using strain-gauges and predicts full-field strain over the entire structure. However, for many structures, it is challenging to accurately model the geometry or material properties for finite element analysis. Many of these structures are made of composite materials and material modes for these structures might not be readily available. In this paper, we use the strain mode shapes extracted using Digital Image Correlation (DIC) in the expansion process. These mode shapes represent actual properties of the structures. The strain mode shapes for a sample structure of a product can be extracted in a test facility using this approach (e.g., a wind turbine blade or a suspension A-arm). An in situ limited set of measurement can be performed using strain-gauges or fiber optic sensors on the structure. Then, the limited data can be expanded using the strain mode shapes to extract full-field strain results. To demonstrate the merit of the approach, we applied the proposed technique to expand real-time operating data measured using a few strain-gauges mounted to a composite spoiler. Using a transformation matrix generated using the DIC operating deflection shapes, the expansion technique predicted the full field strain on the spoiler. It was shown that the proposed methodology could effectively expand the strain data at limited locations to accurately predict the strain at locations where no sensors were placed. © 2019","Composite materials; Condensation techniques; Digital image correlation; Modal expansion; Strain mode shapes; Structural health monitoring","Automotive industry; Composite materials; Condition monitoring; Fiber optic sensors; Finite element method; Image analysis; Linear transformations; Location; Matrix algebra; Metadata; Strain gages; Strain measurement; Turbomachine blades; Wind turbines; Condensation techniques; Conventional methods; D. digital image correlation (DIC); Digital image correlations; Modal expansion; Operating deflection shapes; Strain mode shapes; Transformation matrices; Structural health monitoring",,,,,"National Science Foundation, NSF: 1625987; Kettering University","This research presented in this paper is partly supported by the National Science Foundation under Grant Number 1625987 (Acquisition of a 3D Digital Image Correlation System to Enhance Research and Teaching at Kettering University).

Firstly, based on the stochastic vibration theory, the probabilistic pounding model was developed to model the influence of different seismic intensity levels and local soil condition on determination of the required separation gap between bridge segments. Then, the varying relationship between exceedance probability of pounding and seismic intensity measure (PGA) was derived. The proposed probability-based pounding evaluation approach was applied to a real bridge for predicting the pounding occurrence under various seismic intensity levels, along with the finite element model of the bridge pounding system built in ANSYS. Finally the pounding risk assessment beyond the required separation length of the bridge structure was conducted and presented based on the required separation distance. The results of this study delivered explicit and direct specifications and guidelines for seismic pounding design of bridges with different separation gap. © 2019 Elsevier Ltd","Pounding of bridge; Pseudo excitation method; Required separation distance; Seismic risk analysis; Stochastic vibration analysis","Risk analysis; Risk assessment; Seismic design; Seismology; Stochastic models; Stochastic systems; Vibration analysis; Evaluation approach; Exceedance probability; Pseudo excitation methods; Seismic excitations; Seismic intensity measures; Separation distances; Stochastic vibration; Stochastic vibration analysis; Bridges; bridge; dynamic analysis; dynamic response; earthquake engineering; finite element method; ground motion; risk assessment; seismic design; seismic response; stochasticity; structural response; vibration",,,,,"National Natural Science Foundation of China, NSFC: 51308465; China Postdoctoral Science Foundation: 2015M580031; Department of Science and Technology of Sichuan Province: 2019YJ0243","The research for this paper was supported by the Science and Technology Plan of Sichuan Science and Technology Department (No. 2019YJ0243 ), National Natural Science Foundation of China (No. 51308465 ), and Postdoctoral Science Foundation of China (No. 2015M580031 ).

Based on the geometrical dimensions of a real cable-stayed bridge with a steel girder and cables in addition to a normal concrete (NC) pylon and main-span of 1088 m, a new counterpart cable-stayed bridge using CFRP cables and a UHPC girder and pylon was designed. The dimensions of the UHPC girder were quantified by the section stiffness, punching resistance, local stability, and shearing resistance. The cross-section sizes of the CFRP cables were determined by the principle of equivalent strength. The geometric and physical conditions of the UHPC pylon satisfied the principle of similarity theory. Using the finite element method, a comparative analysis of the mechanical behavior of two cable-stayed bridge schemes was conducted, specifically regarding the static behavior, global stability, aerostatic stability, dynamic mode, and seismic performance. The results indicated that the detailed design and superior performance of the CFRP and UHPC made it practical to form a highly efficient and durable concrete cable-stayed bridge system with CFRP cables and UHPC members. Moreover, these properties could enlarge the main-span of a concrete cable-stayed bridge to approximately 1000 m. © 2018 Elsevier Ltd","Cable-stayed bridge; CFRP cables; FEM; Super-long span; UHPC girder","Beams and girders; Bridge cables; Buffeting; Carbon fiber reinforced plastics; Fiber reinforced plastics; Finite element method; High performance concrete; Reinforced concrete; Aerostatic stabilities; Carbon fiber reinforced polymer; Comparative analysis; Concrete cable-stayed bridges; Geometrical dimensions; Structural behaviors; Super longs; Ultra high performance concretes; Cable stayed bridges",,,,,"National Natural Science Foundation of China, NSFC: 51078134","This work was supported by the National Natural Science Foundation of China (Grant No. 51078134) and Department of Transportation of Jiangxi Province (Grant No. 2016C0008).

Ultra-high-performance concrete (UHPC), which has excellent mechanical properties, was employed as the main material of the prefabricated deck. Special connecting configurations, that is, steel plates with studs or pretensioned rebar, were used for enhancing the crack resistance of the steel-UHPC interface and facilitating convenient on-site assembly. Two sets of specimens featuring passive and active crack resistance were tested for investigation of the behavior of the composite deck under negative moment. The tests showed that the fully prefabricated composite deck provided satisfactory crack resistance compared with a traditional cast-in-place construction composite deck. On the basis of physical testing, a numerical model was built with Abaqus for further parametric analysis. Several design parameters were evaluated through supplementary analyses and recommendations were made for rebar pretension force and beam stiffener height. © 2019 American Society of Civil Engineers.","Crack resistance; Finite-element model; Fully prefabricated construction; Parametric analysis; Pretensioned rebar; Steel-ultra-high-performance concrete (UHPC) composite deck","Bridge decks; Cracks; Finite element method; Mechanical properties; Microalloyed steel; Accelerated constructions; Bridge engineering; Cast-in-place construction; Crack resistance; Design parameters; Parametric -analysis; Pretensioned; Ultra high performance concretes; High performance concrete",,,,,"National Natural Science Foundation of China, NSFC: 51708466; Department of Science and Technology of Sichuan Province, SPDST: 2019YFH0139; Fundamental Research Funds for the Central Universities: 2682017CX002","This work was completed under the support of the Natural Science Foundation of China (Grant No. 51708466), Science and Technology Project of Sichuan Province (Grant No. 2019YFH0139), and Fundamental Research Funds for the Central Universities (Grant No. 2682017CX002).

The former approach tries to identify damage by relating the monitoring data to the prediction of numerical (e.g., finite-element) models of the structure. The latter approach is data driven, where measured data from a given state condition are compared to the baseline or reference condition. A challenge in both approaches is to make the distinction between the changes of the structural response caused by damage and environmental or operational variability. This issue was tackled here using a hybrid technique that integrates model- and data-based approaches into structural health monitoring. Data recorded in situ under normal conditions were combined with data obtained from finite-element simulations of more extreme environmental and operational scenarios and input into the training process of machine-learning algorithms for damage detection. The addition of simulated data enabled a sharper classification of damage by avoiding false positives induced by wide environmental and operational variability. The procedure was applied to the Z-24 Bridge, for which 1 year of continuous monitoring data were available. © 2019 American Society of Civil Engineers.","Damage detection; Damage identification; Finite-element modeling; Machine learning; Structural health monitoring","Damage detection; Finite element method; Learning algorithms; Learning systems; Machine learning; Monitoring; Continuous monitoring; Damage Identification; Environmental variations; Finite element simulations; Machine learning approaches; Operational scenario; Reference condition; Structural response; Structural health monitoring",,,,,,,,,,,,,,,,"Barthorpe, R.J., (2010) On Model- And Data-based Approaches to Structural Health Monitoring, , Ph.

In this article, a novel methodology for extracting and analyzing distributed acceleration data for condition assessment of bridge girders is proposed. Three different techniques are fused, enabling robust damage detection, localization, and quantification. First, stochastic subspace identification is used as an output-only method to extract modal properties of the monitored structure. Second, a reduced-order stiffness matrix is reconstructed from the stochastic subspace identification data using the system equivalent reduction expansion process. Third, a particle swarm optimization algorithm is used to update a finite element model of the bridge girder to match the extracted reduced-order stiffness matrix and modal properties. The proposed approach is first verified through numerically simulated data of the girder and then validated using experimental data obtained from a full-scale pretensioned concrete beam that experienced two distinct states of damage. Results show that the method is capable of localizing and quantifying damages along the girder with good accuracy, and that results can be used to create a high-fidelity finite element model of the girder that could be leveraged for condition prognosis and forecasting. © The Author(s) 2019.","output only; particle swarm; Vibration-based","Damage detection; Data reduction; Finite element method; Highway bridges; Particle swarm optimization (PSO); Plate girder bridges; Stiffness; Stiffness matrix; Stochastic models; Stochastic systems; Structural health monitoring; Output only; Particle swarm; Pre-tensioned concrete; Pretensioned concrete beams; Stochastic subspace identification; Three different techniques; Vibration-based; Vibration-based damage; Concrete beams and girders",,,,,"National Science Foundation, NSF: 1537626; California Department of Transportation, CT: 65A0586","The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This study is partly supported by the California Department of Transportation (grant no.: 65A0586), and the National Science Foundation (grant no.: 1537626).

The original contribution in this work is that these two novel methods are combined to detect damage in a bridge. The damage was simulated in a real bridge in Vietnam, i.e. Ca-Non Bridge. Finite Element Method (FEM) of this bridge was used to show the reliability of the proposed technique. The vibration responses at some points of the bridge under a moving truck are simulated and used to calculate the transmissibility functions. These functions are then used as input data to train the ANNs, in which the target is the location and the severity of the damage in the bridge. After training successfully, the network can be used to assess the damage. Although simulated responses data are used in this paper, the practical application of the technique to real bridge data is potentially high.

By using reduced order models for the calculation of electrical parasitics of the layout and thermal coupling between devices, optimal trace layout and die placement can be simultaneously achieved orders of magnitude faster than conventional finite element analysis (FEA) techniques. An overview of the tool, its modeling methods, model validation, and module layout optimization are presented. The electrical and thermal models are validated against FEA simulations and physical measurements of built modules generated from the tool. The FEA comparisons are performed with FastHenry and ANSYS Icepak to evaluate electrical parasitics and thermal behavior, respectively. A sample hardware prototype based on a half-bridge circuit topology is chosen for testing. Excellent agreement between the FEA simulations, experimental measurements, and PowerSynth predictions are demonstrated. Additionally, when compared with conventional simulation runtime and workflow, PowerSynth takes considerably less computation and user time to produce several candidate layout solutions from which a designer may easily balance selected tradeoffs. © 1986-2012 IEEE.","Design automation; layout; optimization methods; power electronics; semiconductor device packaging","Chip scale packages; Computer aided design; Digital libraries; Libraries; Multichip modules; Multiobjective optimization; Optimization; Power electronics; Semiconductor devices; Substrates; Tools; Trace elements; Design automations; Integrated circuit modeling; Layout; Optimization method; Semiconductor device packaging; Semiconductor device models",,,,,"National Science Foundation, NSF: 1509787, 2014-00555-04, IIP0934390","Manuscript received April 25, 2018; revised July 17, 2018; accepted August 23, 2018.

An inverted functionally graded material (IFGM) arch is developed to promote the critical buckling pressure of the heated arch without variation of the volume portion of the material constituents of the CFGM arch. Based on the classical thin-walled arch theories and admissible displacement functions, the total potential energy function of the IFGM arch is obtained. By variation of this energy function, the non-linear bifurcation equilibrium equations are established, and the analytical prediction of the critical buckling pressure is obtained for the IFGM arch. Subsequently, a two-dimensional (2D) finite element model (FEM) is established to trace the pressure-displacement equilibrium paths to obtain the maximum pressure (critical buckling pressure). The numerical results show very close agreement with the present analytical solutions. Furthermore, the IFGM arch shows a substantial increase of the critical buckling pressure compared with the CFGM arch. In addition, the critical buckling pressure of the heated homogeneous arch is compared with the available other closed-form expressions. Finally, to further understand the stability of the pressurized IFGM arch under temperature rise field, parametric studies are performed to examine the effects of the various involved parameters, such as the volume fraction exponent and temperature rise on the bending moment, the hoop force, the hoop strain and stress, the radial and hoop displacement through the arch span. © 2019 Elsevier Ltd","Bifurcation buckling; Conventional functionally graded material (CFGM); External pressure; FEM; Inverted functionally graded material (IFGM); Temperature rise field; Thin-walled arch","Arches; Beams and girders; Bifurcation (mathematics); Finite element method; Functionally graded materials; Potential energy functions; Thin walled structures; Trace elements; Bifurcation buckling; Conventional functionally graded material (CFGM); External pressures; Inverted functionally graded material (IFGM); Temperature rise; Thin-walled; Arch bridges",,,,,"Iowa State University, ISU; National Natural Science Foundation of China, NSFC: 51878119","The Department of Civil, Construction and Environmental Engineering of Iowa State University provides partial financial supports to this study.

The collision characteristic of bow structure is significant to the study ship-pier collision process. In this paper, the quasi-static compression test and numerical simulation of a simplified bow model were carried out to study the static stiffness characteristic of the ship bow for further comparison with the dynamic ones. To evaluate the performance of reinforced concrete (RC) piers against ship collision, and to guide the design of the bridge piers and anti-collision, scaled model tests of ship-pier collision and finite element simulations based on the main pier no. 217 of the Shijiu Lake Bridge were carried out. The damage process and failure mode of the pier were analysed. Instead of rigid or elastic materials in most of the previous works of numerical simulation of ship collision with bridge piers, the bridge pier is modelled with nonlinear materials to simulate the pier characteristics more accurately. To examine the reasonability of the scaled model tests, finite element analysis of the full-scale ship-pier collision was conducted. In the light of the numerical results, the design impact loads prescribed by Eurocode and AASHTO LRFD Bridge Design Specifications were evaluated. Parametric studies were carried out to investigate the effects of the dynamic parameters and impact velocity on the impact force and ship bow crush depth. © 2018","Impact force; Nonlinear numerical simulation; Scaled model test; Ship-pier collision","Bridge piers; Collision avoidance; Compression testing; Concrete testing; Disasters; Finite element method; Numerical models; Reinforced concrete; Ship testing; Ships; Experimental testing; Finite element simulations; Impact force; Nonlinear materials; Nonlinear numerical simulation; Quasi-static compression; Reinforced concrete pier; Scaled model tests; Failure (mechanical)",,,,,"National Natural Science Foundation of China, NSFC: 51578285, 51778285; Natural Science Foundation of Jiangsu Province: BK20161545","The research described here was supported by the National Natural Science Foundation of China (grant nos. 51578285 and 51778285 ) and the Natural Science Foundation of Jiangsu Province (grant no.

Currently the correlation between rust development/removal process and the structural/environmental performance of the steel bridges has not been fully understood. This study intends to fill this knowledge gap through critically reviewing. The characteristic analysis of the rust on the corroded steel bridges was first introduced, which provided information that was needed to understand the corrosion mechanisms and classify the rust type. Then the related rust removal techniques (chemical and physical methods) are analyzed by considering the environmental impact and cleaning efficiency. Based on the discussion, the laser cleaning method is proposed due to its cleaning efficiency and environmentally friendliness. After that, the influence of developed rust (uniform and pitting) on the structural performance (static and dynamic) of steel members were summarized. Through the discussion, the potential environmental impact of the corroded steel bridges was identified, including runoff of heavy metal and bacteria growth caused by iron rust. Besides that, an improved kinetic model was proposed by considering the influence of rust removal on the corrosion rate. Furthermore, the structural impact of laser cleaning was simulated with the finite element analysis. This study will serve as solid base for the future studies of corrosion development and rust removal on steel bridges, and the proposed technical routes can be proceeded during future studies to better understand the environmental and structural performance of the steel bridges. © 2019 Elsevier Ltd","Environmental impact; Laser cleaning; Pitting; Rust corrosion; Steel bridges; Uniform corrosion","Chemical analysis; Chemical cleaning; Classification (of information); Corrosion rate; Efficiency; Environmental impact; Heavy metals; Pitting; Steel bridges; Characteristic analysis; Cleaning efficiency; Corrosion mechanisms; Kinetic modeling; Laser cleaning; Structural impact; Structural performance; Uniform corrosion; Steel corrosion",,,,,"Department of Environmental Quality, DEQ; China Scholarship Council, CSC: 201406370141","The authors would like to acknowledge the partial financial support from the Michigan Department of Environmental Quality under grant No. CU-1631059 .

To this end, this approach integrates the terrestrial laser scanner, the sonic and impact-echo methods, the ground penetrating radar and the multichannel analysis of surface waves. All these data are combined with reverse engineering procedures, allowing the creation of suitable as-built CAD models for advanced numerical simulations. Then, these numerical models are contrasted and updated through the data provided by the ambient vibration tests. To validate the methodology proposed in this paper, the Roman bridge of Avila was used as study case. This bridge shows a complex mixture of constructive techniques (masonry, cohesive material, Opus Caementicium and reinforced concrete). Thus, the numerical model was considered for performing predictive structural analysis. © 2019 Elsevier B.V.","Ambient vibration tests; Finite element method; Ground penetrating radar; Historical constructions; Masonry arch bridge; Multichannel analysis of surface waves; Non-destructive testing; Non-linear analysis; Sonic testing; Terrestrial laser scanner","Arch bridges; Arches; Concrete mixtures; Finite element method; Geological surveys; Geophysical prospecting; Ground penetrating radar systems; Laser applications; Masonry bridges; Masonry construction; Nondestructive examination; Numerical models; Reinforced concrete; Reverse engineering; Scanning; Structural analysis; Surface waves; Surveying instruments; Ambient vibration test; Ground Penetrating Radar; Historical construction; Masonry arch bridges; Multi-channel analysis of surface waves; Non destructive testing; Sonic testing; Terrestrial laser scanners; Vibration analysis",,,,,"European Regional Development Fund, FEDER: SOE1/P5/P0258; Junta de Castilla y León: SA075P17","This work was financed by ERDF funds through the V SUDOE INTERREG program within the framework of the HeritageCARE project, Ref.

These concentric-loading (CL) stress-strain models have generally been used in the analysis of both concentrically and eccentrically loaded columns. Existing tests, however, have shown that eccentrically loaded FRP-confined concrete columns exhibit some behavioral aspects that cannot be closely predicted using a CL stress-strain model. This paper presents an in-depth investigation into this problem using an advanced three-dimensional (3D) finite element (FE) approach. The stress-strain response of concrete is shown to vary significantly over the section, and the direct use of a single CL stress-strain model for the entire section in the analysis of eccentrically loaded columns may lead to significant errors in the prediction of ultimate displacement/curvature. A stress-strain model for the confined concrete at the extreme compression fiber of the section is also shown to provide a relatively simple and much more accurate option for predicting the ultimate displacement/curvature of eccentrically loaded columns. Based on this conclusion, a so-called eccentricity-dependent (EccD) stress-strain model is proposed based on a comprehensive parametric study using the FE approach. The proposed model can be directly used in a section analysis or a theoretical column model and is proven to provide much more accurate predictions of the ultimate displacement/curvature of test columns than existing CL stress-strain models. © 2019 American Society of Civil Engineers.","Column; Concrete; Confinement; Eccentric loading; Fiber-reinforced polymers (FRP); Finite element analysis; Stress-strain model","Bridge decks; Columns (structural); Concrete construction; Concretes; Fiber reinforced plastics; Forecasting; Plasma confinement; Polymers; Reinforced concrete; Reinforced plastics; Reinforcement; Stress-strain curves; Confined concrete columns; Eccentric loading; Eccentrically loaded column; Extreme compression fiber; Fiber reinforced polymers; Frp confined concrete columns; Stress-strain model; Threedimensional (3-d); Finite element method",,,,,"2017YFC0703000","The authors are grateful for the financial support received from the National Key R&D Program of China (Project No. 2017YFC0703000) and the Research Grants Council of the Hong Kong Special Administrative Region (Project Reference Nos.

For crane designs, the crane bridge is one of the most critical systems, as its mechanical skeleton bearing and transferring the operational load and the weight of the crane itself thus must be designed with sufficient reliability in order to ensure safe crane services. Due to extremely expensive computational costs, current crane bridge design has been primarily focused either on deterministic design based on conventional design formula with empirical parameters from designers’ experiences or on reliability-based design by employing finite-element analysis. To remove this barrier, the paper presents the study of using an advanced surrogate modeling technique for the reliability-based design of the crane bridge system to address the computational challenges and thus enhance design efficiency. The Kriging surrogate models are first developed for the performance functions for the crane system design and used for the reliability-based design optimization.

Among different damage detection techniques, guided wave–based approach has been the subject of intensive research activities. This article investigates the capability of Rayleigh wave for debonding detection in fibre-reinforced polymer-retrofitted concrete structures through studying wave scattering phenomenon at debonding between fibre-reinforced polymer and concrete. A three-dimensional finite element model is presented to simulate Rayleigh wave propagation and scattering at the debonding. Numerical simulations of Rayleigh wave propagation are validated with analytical solutions. Absorbing layers by increasing damping is employed in the fibre-reinforced polymer-retrofitted concrete numerical model to maximise computational efficiency in the scattering study. Experimental measurements are also carried out using a three-dimensional laser Doppler vibrometer to validate the three-dimensional finite element model. Very good agreement is observed between the numerical and experimental results. The experimentally and analytically validated finite element model is then used in numerical case studies to investigate the wave scattering characteristic at the debonding. The study investigates the directivity patterns of scattered Rayleigh waves, in both backward and forward directions, with respect to different debonding size-to-wavelength ratios. This study also investigates the suitability of using bonded mass to simulate debonding in the fibre-reinforced polymer-retrofitted concrete structures. By enhancing physical understanding of Rayleigh wave scattering at the debonding between fibre-reinforced polymer/concrete interfaces, this study can lead to further advance of Rayleigh wave–based damage detection techniques. © The Author(s) 2018.","debonding; experiment; fibre-reinforced polymer-retrofitted concrete; finite element; guided wave; Rayleigh wave; scattering; three-dimensional scanning laser vibrometer","Bridge decks; Chemical detection; Composite bridges; Computational efficiency; Concrete buildings; Concrete construction; Concretes; Damage detection; Experiments; Fiber reinforced plastics; Fibers; Finite element method; Forward scattering; Guided electromagnetic wave propagation; Numerical models; Polymers; Rayleigh waves; Reinforced plastics; Reinforcement; Scattering; Structural health monitoring; Vibration measurement; Damage detection technique; Directivity pattern; Fibre reinforced polymers; Laser Doppler vibrometers; Rayleigh wave scattering; Scattering char-acteristics; Three dimensional finite element model; Three-dimensional scanning; Debonding",,,,,"Australian Research Council, ARC: DE130100261","The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This work was support by the Australian Research Council (ARC) under Grant Number DE130100261.

To achieve a large motion stroke, compact structure and good decoupling performance, a novel displacement amplifier including L-shape levers and half-bridge (LSLHB) is proposed. By utilizing a concave input mechanism for location restriction between PEA and flexible mechanism, the motion coupling caused by the inconsistent central axes of the PEA and input mechanism is eliminated. The XYZ micro/nano positioner mainly consists of a parallel XY stage and a Z stage nested on the XY stage. The XY stage is constructed with four LSLHB amplifiers which are orthogonally arranged to realize X- and Y- axis motion and kinematic decoupling. The characteristics of the positioner are studied by analytical modeling and finite element analysis. The XYZ micro/nano positioner is manufactured by wire electrical discharge machining, and the performance of the positioner is evaluated through experimental tests. The results show that the stage can implement three degree-of-freedom translational motion with a workspace of 128.1 μm×131.3 μm×17.9 μm, and the coupling errors in the non-working direction is less than 1.56 % of the motion stroke, and motion resolution is 8 nm. © 2019 Elsevier B.V.","Concave input mechanism; L-shape levers and half-bridge amplifier; Micro/nano positioner; Piezoelectric actuator","Degrees of freedom (mechanics); Electric discharge machining; Electric discharges; Piezoelectricity; Displacement amplifier; Experimental validations; Half bridge; Input mechanisms; Micro/nano; Three degree of freedoms; Translational motions; Wire electrical discharge machining; Piezoelectric actuators",,,,,"734174; National Natural Science Foundation of China, NSFC: 51675367, 51675371, 51675376; Science and Technology Commission of Shanghai Municipality, STCSM: 18PTZWHZ00160, 19PTZWHZ00010; Tianjin Science and Technology Committee; National Key Research and Development Program of China, NKRDPC: 2016YFE0112100, 2017YFB1104700, 2017YFE0112100, 2019YFB1301502","This research was supported by National Natural Science Foundation of China (Grant nos. 51675371 , 51675376 , and 51675367 ), National Key R&D Program of China (nos. 2017YFB1104700 , 2019YFB1301502 , 2017YFE0112100 , and 2016YFE0112100 ), Science & Technology Commission of Tianjin Municipality (Grant nos. 19PTZWHZ00010 , and 18PTZWHZ00160 ) and China-EU H2020 MNR4SCell (no. 734174 ).

In this study, we develop a parametric model to generate arterial geometries and accumulate a database of 12,172 2D finite element simulations modeling the hyperelastic behavior and resulting stress distribution. The arterial wall composition mimics vessels in atherosclerosis-A complex cardiovascular disease and one of the leading causes of death globally. We formulate the training data to predict the maximum von Mises stress, which could indicate risk of plaque rupture. Trained deep learning models are able to accurately predict the max von Mises stress within 9.86% error on a held-out test set. The deep neural networks outperform alternative prediction models and performance scales with amount of training data. Lastly, we examine the importance of contributing features on stress value and location prediction to gain intuitions on the underlying process. Moreover, deep neural networks can capture the functional mapping described by the finite element method, which has far-reaching implications for real-Time and multiscale prediction tasks in biomechanics. © 2019 by ASME.",,"Deep neural networks; Diseases; Forecasting; Machine learning; 2D finite element simulation; Cardio-vascular disease; Functional mapping; Hyperelastic behavior; Location prediction; Machine learning models; Multiscale predictions; Parametric modeling; Finite element method; artery wall; Article; artificial neural network; atherosclerosis; atherosclerotic plaque; biomechanics; cardiovascular disease; deep learning; elasticity; finite element analysis; geometry; machine learning; measurement accuracy; prediction; statistical analysis; statistical model; wall stress",,,,,"American Heart Association, AHA: AHA-16IRG27630014; University of Capetown, UCT","We thank Jonas Landman for his rotation research contributions and other members of the Molecular Cell Biomechanics Laboratory for fruitful discussions that benefited this project.

In this paper, we employ the Finite Element Method (FEM) with an effective mesh-moving algorithm to simulate the forced-vibration experiments of bridge sectional models. We have augmented the formulation with weakly-enforced essential boundary conditions, and a numerical example illustrates how weak enforcement of the no-slip boundary condition gives a very accurate representation of the aeroelastic forces in the case of relatively coarse boundary layer mesh resolution. To demonstrate the accuracy of the method for industrial applications, the complete aerodynamic derivatives for lateral, vertical and pitching degrees-of-freedom are computed for two bridge deck sectional models and compared with experimental wind-tunnel results. Although some discrepancies are seen in the high range of reduced velocities, the proposed numerical framework generally reproduces the experiments with good accuracy and proves to be a beneficial tool in simulation of bluff body aerodynamics for bridge design. © 2018","Aerodynamic derivatives; Aeroelasticity; ALE-VMS; Bridge aerodynamics; Finite element method","Aerodynamics; Aeroelasticity; Boundary conditions; Boundary layers; Bridges; Computational fluid dynamics; Degrees of freedom (mechanics); Mesh generation; Wind tunnels; Aerodynamic derivatives; Ale-vms; Bluff body aerodynamics; Bridge aerodynamics; Mesh moving algorithms; No-slip boundary conditions; Weakly enforced essential boundary conditions; Wind tunnel experiment; Finite element method",,,,,"Army Research Office, ARO: W911NF-14-1-0296; Norges Teknisk-Naturvitenskapelige Universitet, NTNU; Natural Sciences and Engineering Research Council of Canada, NSERC: RGPIN-2017-03781; Statens vegvesen","This work was carried out with financial support from the Norwegian Public Roads Administration (NPRA).

The uncoupling method shows advances in characterizing the nonlinear wheel-rail contacts in geometries and forces but needing to strictly satisfy solution convergence by small time step size, or iterative procedures and other alternatives needed. While for the coupling method, it possesses fairly high computational stability by satisfying geometrical compatibility and force equilibrium automatically, but there still exist large deficiencies in revealing wheel-rail contact geometries/creepages with higher efficiency and refinement, especially with consideration of wheel-rail separations. In this paper, a three-dimensional (3-D) model for train-track-bridge interaction is proposed under the fundamentals of strongly coupling strategy with innovative methodologies. Firstly a coupling matrix for track-bridge finite element system is constructed, in which a versatile method founded on energy principle is developed. Through this method, the elemental number and form of bridges can be arbitrarily chosen. Then the key matrices for coupling the train and the track-bridge system are presented in detail, especially the matrix formulations corresponding to wheel-rail separations are introduced. Through a particular examination of this newly developed train-track-bridge dynamic model, it is found out that this model shows high computational stability, accuracy and efficiency comparing to conventional solutions; besides some key parameters such as the bridge elemental length, track-bridge section length in numerical integrations can be clarified by this model conveniently. © 2019 Elsevier Ltd","Dynamic analysis; Finite element method; Train-bridge interaction matrices; Train-track-bridge interaction; Wheel-rail separations","Dynamic analysis; Geometry; Iterative methods; Railroad bridges; Separation; Vehicle wheels; Computational stability; Innovative methodologies; Numerical integrations; Three dimensional (3-D) modeling; Three-dimensional model; Train tracks; Train-bridge interaction; Wheel-rail; Finite element method",,,,,"National Natural Science Foundation of China, NSFC: 11790283, 51678507, 51735012; State Key Laboratory of Traction Power: 2019TPL-T10; Project 211: B16041","This work was supported by the key National Natural Science Foundation of China [grant number 11790283 ; 51735012 ; 51678507 ]; the Program of Introducing Talents of Discipline to Universities (111 Project) [grant number B16041 ]; the Independent Research Project of State Key Laboratory of Traction Power [grant number 2019TPL-T10].",,,,,,,,,,"Dahlberg, T., Vehicle-bridge interaction (1984) Veh.

Those with a span greater than 12 m are usually equipped with additional stiffening elements, e.g. ribs, relieving slabs, longitudinal beams, steel ribs and steel ribs filled with concrete. This paper examines the necessity of using these additional stiffening elements, using the example of a soil-steel bridge with a span of over 17 m. Stiffening steel ribs filled with concrete were used in this bridge, and the behaviour of the corrugated steel shell of the bridge was then analysed under backfilling loads. The DIANA program with the finite element method was used for the numerical analysis. The maximum displacements, bending moments and axial forces for the three numerical models of corrugated steel shell were considered, and the displacements obtained from numerical calculations were compared with measured results. In addition, the bending moments and axial forces obtained using finite element analysis were compared with results based on the relevant standards and design methods. © 2019 Elsevier Ltd","Backfilling; Corrugated steel plate; Shell model; Soil-steel bridge; Steel ribs; Stiffening","Axial flow; Bending moments; Concretes; Numerical methods; Shells (structures); Soils; Steel bridges; Backfilling; Corrugated steel; Shell models; Soil-steel bridges; Steel ribs; Stiffening; Finite element method; backfill; bridge; numerical model; shell; steel; stiffness",,,,,,,,,,,,,,,,"Machelski, C., Construction of soil-shell structures (2013), The Lower Silesian Educational Publishers Wroclaw; Machelski, C., Steel plate curvatures of soil-steel structures during construction and exploitation (2016) Roads and Bridges - Drogi i Mosty, 15 (3), pp. 207-220; Janusz, L., Madaj, A., Engineering structures from corrugated plates.

This 300m long bridge can be considered as a unique representative example of pioneering research on the design and construction of optimized structures. First, the design process employed for determining the form of the shell and the relevant constructive issues are described. A refined 3D geometric model of the shell is then obtained through an aerial survey carried out by a commercial UAV and a photogrammetric image-based reconstruction. A recent formulation of the Force Density Method allowing for non-isotropic stress state is exploited to numerically derive the form of the supporting shell; it is validated versus the surveyed geometry of the shell by employing a nonlinear optimization procedure in order to identify forces and stresses to be used as input parameters. Finally, the derived form of the shell is tested by a Finite Element analysis to verify its funicular efficiency, i.e., whether it is capable to withstand design loads by pure membrane actions. © 2019 Elsevier Ltd","Bridge over the Basento river; Force density method; Form finding; Musmeci; Optimal form; RC shell; UAV geometric survey","3D modeling; Antennas; Curve fitting; Geometry; Nonlinear programming; Rivers; Shells (structures); Surveys; Three dimensional computer graphics; Unmanned aerial vehicles (UAV); Force density methods; Form finding; Musmeci; Optimal forms; RC shell; Bridges; bending; bridge; construction; design; finite element method; geometry; reinforced concrete; survey; three-dimensional modeling; unmanned vehicle; Basento River; Basilicata; Italy; Potenza; Sergio",,,,,,,,,,,,,,,,"Adriaenssens, S., Boegle, A., Innovative structural typologies (2016) Innovat Bridge Des Handbook, pp. 195-209. , chapter 8; Adriaenssens, S., Block, P., Veenendaal, D., Williams, C., Shell structures for architecture: form finding and optimization (2014), Routledge; Adriaenssens, S., Schmidt, K., Katz, A., Gabriele, S., Varano, V., (2015), Early form finding techniques of Sergio Musmeci revisited.

In this paper, an orthotropic steel bridge (OSB) stiffened with UHPC layer is modeled via the finite element submodel technique. The stress responses of fatigue-prone details under wheel loads are obtained, and the fatigue performance is also evaluated. The stress tendencies observed by the finite element models are compared to the stress response data from field measurements. It is observed that an application of 45 mm thick UHPC layer on the OSB deck can reduce the stress range at deck side of rib-to-deck (RD) joint by up to 70.9%, achieving an infinite fatigue life. However, the stress ranges for the other three details are still significant, including the stress range at rib side of RD joint (with both membrane and bending stresses), the stress range on rib wall at weld end of rib-to-floorbeam (RF) joint (with both rotational and Poisson's effects), and the stress range at floorbeam side of RF joint (due to the in-plane deformation and out-of-plane twist). To reduce such significant stress ranges in achieving infinite fatigue life of the bridge under high traffic volume, the critical influencing parameters on the stress ranges are studied and selected for fatigue design. © 2019","Fatigue; Fatigue life; Finite element method; Orthotropic steel deck; Stress range; Ultra-high performance concrete","Bridge decks; Finite element method; High performance concrete; Steel bridges; Cement based material; Fatigue performance; Field measurement; In-plane deformation; Influencing parameters; Orthotropic steel decks; Stress range; Ultra high performance concretes; Fatigue of materials",,,,,"201522; National Natural Science Foundation of China, NSFC: 51878269; National Key Research and Development Program of China, NKRDPC: 2015CB057701","This work is funded by the National Basic Research Program of China (973 Program) [grant number 2015CB057701 ], the National Natural Science Foundation of China [grant number 51878269 ] and the Communication Science and Technology Project in the Hunan Province of China [grant number 201522 ].

First, by modeling the vehicle as two concentrated loads moving over the bridge, closed-form solutions for the responses of the contact points are obtained. Second, by treating the vehicle as a two degree-of-freedom (DOF) system, closed-form solutions for the coupled vertical and rotational responses of the vehicle due to contact-point excitations are obtained. From vehicle's frequency response functions (FRFs), various phenomena are studied, including coupling, uncoupling, beat, resonance and cancellation. Resonance occurs when any excitation frequency coincides with any of the vehicle frequencies. No cancellation is observed when the two-DOF asymmetric vehicle degenerates into the uncoupled mode or a single-DOF vehicle. The results obtained are verified by an independent finite element analysis with virtually no assumptions. The advantage of using the two-axle asymmetric vehicle to scan the frequencies of the sustaining bridge is explored theoretically and numerically. © 2018 Elsevier Ltd","Bridge; Cancellation; Resonance;

An updated model provides more accurate prediction of structural behavior in future analyses. Sensitivity-based parameter clustering and regularization are two techniques used to improve model updating solutions, particularly for high-dimensional parameter spaces and ill-posed updating problems. In this paper, a novel parameter clustering scheme is proposed which considers the structure of the objective function to facilitate simultaneous updating of disparate data, such as natural frequencies and mode shapes. Levenberg–Marquardt minimization with Bayesian regularization is also implemented, providing an optimal regularized solution and insight into parametrization efficiency. In a small-scale updating example with simulated data, the proposed clustering scheme is shown to provide moderate to excellent improvement over existing parameter clustering methods, depending on the accuracy of initial model. A full-scale updating example on a large suspension bridge shows similar improvement using the proposed parametrization scheme. © 2018 Elsevier Ltd","Finite element model updating; Parametrization; Regularization; Sensitivity-based clustering; Sensitivity-based model updating","Sensitivity analysis; Based clustering; Finite-element model updating; Model updating; Parametrizations; Regularization; Finite element method",,,,,"College and Graduate School of Arts and Sciences","The authors gratefully acknowledge Columbia University’s Graduate School of Arts and Sciences in support of the first author through the Guggenheim Fellowship and Presidential Fellowship.

Currently, there is a significant paucity in the literature on nonlinear mechanics and dynamics of PPS piers. Hence, this wok numerically investigates the nonlinear static and dynamic behaviour of PPS piers using a finite element (FE) framework. Nonlinear static and dynamic analyses are performed, and the results are compared for non-tapered and tapered PPS as well as cast-in-place (CIP) piers. It is found that post-tensioning force, aspect ratio, axial force of the pier, and number of segments highly affect nonlinear behaviour of the PPS piers. High levels of excitation amplitudes exhibit co-existing (high/low) amplitude responses at and around the resonant frequency of the PPS piers, and tapering enhances the probability of dynamic instability in the PPS pier. It is also shown that the fundamental mode of the PPS piers is similar to the first mode of a CIP bridge pier. © 2019 The Authors","Accelerated bridge construction; Frequency response functions; Nonlinear dynamic;

During a seismic event, these isolators simultaneously experience the service loads and the base shear loads. It is therefore critical to understand their mechanical response under combined loading. In previous studies, researchers designed base isolators with the assumption that the axial loading is compressive. However, the baser isolators may also experience a tensile axial load during a seismic event. Few researchers have investigated the behavior of base isolators with combined axial tensile stress and base shear. This paper uses the finite element method to model the behavior of steel-rubber base isolators under combined axial tension or compression and base shear. The effect of the magnitude and direction of the axial load is investigated for base isolators subject to 375% shear strain. The numerical models suggest that the apparent stiffness of the base isolator increases when the axial load is tensile. The influence of the number and size of rubber cores in the steel-rubber base isolator is also investigated. The results suggest that base isolators with multiple radially-distributed rubber cores outperform those with a single central rubber core. © 2019 Elsevier Ltd","Base isolator; Finite element method; Hyper-elastic; Rubber core; Steel-rubber isolator; Time-history analysis","Axial loads; Bridges; Finite element method; Seismology; Shear flow; Shear strain; Base isolator; Hyper elastic; Rubber core; Rubber isolators; Time history analysis; Rubber; compression; elasticity; finite element method; loading; magnitude; rubber; seismic response; shear strain; steel structure; stiffness; tensile stress; tension",,,,,,,,,,,,,,,,"Chang, C.H., Modeling of laminated rubber bearings using an analytical stiffness matrix (2002) Int J Solids Struct, 39, pp. 6055-6078; Kelly, J.M., Takhirov, S.M., Tension buckling in multilayer elastomeric isolation bearings (2007) J Mech Mater Struct, 2 (8), pp. 1591-1605; Iizuka, M., A macroscopic model for predicting large-deformation behaviors of laminated rubber bearings (2000) Eng Struct, 22, pp. 323-334; Weitzmann, R., Ohsaki, M., Nakashima, M., Simplified methods for design of base-isolated structures in the long-period high-damping range (2006) Earthquake Eng Struct Dyn, 35, pp. 497-515; Abe, M., Yoshida, J., Fujino, Y., Multiaxial behaviors of laminated rubber bearings and their modeling, II: modeling (2004) J Struct Eng, 130 (8), pp. 1133-1144; Yamamoto, M., Minewaki, S., Yoneda, H., Higashino, M., Nonlinear behavior of high-damping rubber bearings under horizontal bidirectional loading: full-scale tests and analytical modeling (2012) Earthquake Eng Struct Dyn, 41 (13), pp. 1845-1860; Takaoka, E., Takenaka, Y., Nimura, A., Shaking table test and analysis method on ultimate behavior of slender baseisolated structure supported by laminated rubber bearings (2010) Earthquake Eng Struct Dyn, 40, pp. 551-570; Kikuchi, M., Nakamura, T., Aiken, I.D., Three-dimensional analysis for square seismic isolation bearings under large shear deformations and high axial loads (2010) Earthquake Eng Struct Dyn, 39, pp. 1513-1531; Moghadam, S.R., Konstantinidis, D., Simple mechanical models for the horizontal behavior of elastomeric bearings including the effect of support rotation (2017) Eng Struct, 150, pp. 996-1012; Kalfas, K.N., Mitoulis, S.A., Katakalos, K., Numerical study on the response of steel-laminated elastomeric bearings subjected to variable axial loads and development of local tensile stresses (2017) Eng Struct, 134, pp. 346-357; Kalfasa, K.N., Mitoulisb, S.A., Performance of steel-laminated rubber bearings subjected to combinations of axial loads and shear strains (2017) Procedia Eng, 199, pp. 2979-2984; Kumar, M., Whittaker, A.S., Cross-platform implementation, verification and validation of advanced mathematical models of elastomeric seismic isolation bearings (2018) Eng Struct, 175, pp. 926-943; Kalpakidis, I.V., Constantinos, M.C., Whittaker, A.S., Modeling strength degradation in lead–rubber bearings under earthquake shaking (2010) Earthquake Eng Struct Dyn, 39, pp. 1533-1549; Nailiang Xianga, M., Alam, S., Lia, J., Shake table studies of a highway bridge model by allowing the sliding of laminated-rubber bearings with and without restraining devices (2018) Eng Struct, 171, pp. 583-601; Zhou, F., Zhang, Z., Wu, D., Zhu, H., An analytical model for predicting the lateral-torsion coupling property of laminated rubber bearings (2018) J Sound Vib, 427, pp. 1-14; Gaurona, O., Saidoua, A., Bussona, A., Siqueira, G.H., Paultrea, P., Experimental determination of the lateral stability and shear failure limit states of bridge rubber bearings (2018) Eng Struct, 174, pp. 39-48; Ohsaki, M., Miyamura, T., Kohiyama, M., Yamashita, T., Yamamoto, M., Nakamura, N., Finite-element analysis of laminated rubber bearing of building frame under seismic excitation (2015) Earthquake Eng Struct Dyn, 44, pp. 1881-1898; Lu, C.H., Liu, K.Y., Chang, K.C., Seismic performance of bridges with rubber bearings: lessons learnt from the 1999 Chi-Chi Taiwan earthquake (2011) J Chin Inst Eng, 34 (7), pp. 889-904; Kwon, O.S., Jeong, S.H., Seismic displacement demands on skewed bridge decks supported on elastomeric bearings (2013) J Earthquake Eng, 17, pp. 998-1022; (2011), Abaqus user's manual;; ASCE 7-16, Minimum design loads for buildings and other structures (2006), American Society of Civil Engineers; EN 1337-3, Structural bearings – Part 3: elastomeric bearings (2005), European Committee for Standardization Brussels; (2003), FEMA 450-1.

This study tests and analyses the thin concrete cladding system which omits conventional steel reinforcement, the use of which requires concrete cover to the reinforcement layer that typically dictates the minimum thickness of the concrete wythes. A total of four full height panels are constructed in a precast concrete facility and are tested by way of three point bending. To complement the experimental study, finite element analysis is used to better understand the bending behaviour beyond what was discerned from the results obtained through experimentation. The experimental results showed that the thin concrete sandwich panel is a plausible solution for precast cladding systems with ultimate moment capacities in excess of those required to meet design wind loads. Ductile behaviour was observed in all of the four tested panels as a result of the high dosage of small 24 mm coated glass fibres used in the mix design for the concrete wythes. The experimental results showed no evidence of the FRP grid connector providing any significant degree of composite action. Finite element analysis suggests that this is due to, one or a combination of, the insulation′s stiffness being too low or because the tensile members in the grid connector being under an initial compressive strain and not fully engaged during initial loading. © 2019 Elsevier Ltd","Carbon fibre reinforced polymer (CFRP) shear connector; Finite element analysis (FEA); Flexural testing; High performance fibre reinforced concrete (HPFRC); Lightweight cladding; Precast concrete sandwich panels (PCSPs)","Bridge decks; Carbon fiber reinforced plastics; Carbon fibers; Concrete testing; Fiber reinforced materials; Finite element method; Foams; High performance concrete; Honeycomb structures; Light weight concrete; Reinforced concrete; Sandwich structures; Structural panels; Carbon fibre reinforced polymer; Concrete sandwich panel; Fibre reinforced concrete; Flexural testing; High-performance fibres; Precast concrete sandwich panels; Shear connector; Ultimate moment capacity; Precast concrete; carbon fiber; finite element method; flexure; polymer; reinforced concrete; structural component",,,,,"European Commission, EC; Horizon 2020: 636717","This work was funded by the European Union as a Horizon 2020 project (IMPRESS) under Grant No. 636717, and the authors would like to express their thanks to the funding bodies and partners for making this possible.

Because of the difference in the structures or material properties, the differential settlement always present. The structural vibration caused by the hanging sleepers is often observed in transition zones, which leads to significant amplification of dynamic responses between the ballast and sleeper, aggravating the track degradation. In order to explain the high degradation rate of the track in transition zones, a 3D dynamic (explicit) Finite Element model of transition zones has been used. It considers that the rapid compaction of ballast tracks occurs after a few months of operation, while the track on the engineering structure barely settles, resulting in the appearance of hanging sleepers in transition zones. Therefore, the model can study the differential settlement and the stiffness variation between the ballast track and the engineering structure at the same time. Nonlinear contact elements are used to model the interface between sleepers and ballast so that the behaviour of hanging sleepers can be better studied. The results show that the differential settlement plays a more important role in track degradation than the stiffness variation. The dynamic behaviours are different in the embankment-bridge and bridge-embankment transitions. The location that the maximum wheel-rail interaction force appears does not correspond to that of the maximum ballast stress. The results explain the degradation mechanism and provide guidance for maintenance. © 2019 Elsevier Ltd","Ballast stress; Dynamic behaviour; Finite element method; Hanging sleeper; Transition zone","Degradation; Dynamic response; Embankments; Railroad tracks; Stiffness; Structural dynamics; Degradation mechanism; Dynamic behaviours; Engineering structures; Hanging sleeper; Stiffness variations; Structural vibrations; Transition zones; Wheel-rail interaction; Finite element method",,,,,,,,,,,,,,,,"Li, D., Davis, D., Transition of railroad bridge approaches (2005) J.

Generally, concrete is poured on the inner side of corrugated steel webs to improve its shear stability, but encased concrete increases the weight of the girder, raises the difficulty of the construction process, and reduces the efficiency of the prestressing application. This paper proposes a new type of stiffened corrugated steel webs at the support area by adopting vertical or/and horizontal stiffeners instead of encased concrete. In order to explore the shear performance of proposed stiffened corrugated steel webs, experimental and numerical investigations were carried out in the present paper and the companion paper [1], respectively. Four steel I-girders with corrugated webs considering different stiffener arrangements were designed and tested under shear loading. The failure modes, shear strength and stiffness, strain distributions were obtained and analyzed in detail. The test results show that all specimens failed due to interactive shear buckling of corrugated steel web; shear buckling occurred between horizontal stiffeners and bottom flange for horizontal stiffened corrugated steel webs, but extended to the entire height for vertical stiffened corrugated steel webs, the stiffeners distorted associated with the deformation of corrugated steel web. Shear strength of corrugated steel webs can be improved by vertical and horizontal stiffeners. The vertical stiffeners do not affect the “accordion effect” of corrugated steel webs, but the horizontal stiffeners increase the axial stiffness of corrugated steel web in local area and resist bending moment together with top and bottom flanges. The shear strain of stiffened corrugated steel web still distributes uniformly along the height of the web. All the experimental results are then employed in the companion paper for the validation of finite element method and the evaluation of existing analytical models for predicting shear strength of un-stiffened and stiffened corrugated steel webs. © 2019 Elsevier Ltd","Composite bridge; Shear bucking failure; Shear capacity; Shear stiffness; Stiffened corrugated steel web; Strain distribution","Beams and girders; Composite bridges; Concretes; Flanges; Shear strain; Stiffness; Corrugated steel webs; Shear bucking; Shear capacity; Shear stiffness; Strain distributions; Steel testing",,,,,"110109039; National Natural Science Foundation of China, NSFC: 51308070","The authors gratefully thank the financial support of National Natural Science Foundation of China ( 51308070 ) and Transportation Science and Technology Project of Sichuan Province ( 110109039 ).",,,,,,,,,,"He, J., Wang, S., Liu, Y., Wang, D., (2019), Haohui Xin, Shear behavior of steel I-girder with stiffened corrugated web, Part II: numerical study, (submited for publication); He, J., Liu, Y., Chen, A., Yoda, T., Mechanical behavior and analysis of composite bridges with corrugated steel webs: state-of-the-art (2012) Int.

Ltd., Chengdu, China","Sichuan–Tibet Railway plays a vital role in China’s transportation system by connecting Tibet and Central China, whose design and construction are extremely difficult due to numerous seismic zones and deep valleys along the railway line. This paper systematically presents a framework to control seismic vibration of T-beam bridges with high-piers in Sichuan–Tibet Railway using tuned mass dampers (TMDs). Firstly, a finite element model of the widely used high-pier bridge is established to reveal its vibration modes subject to earthquakes. On this basis, optimal installation locations and optimal parameters of the TMDs are determined. Then, vibration reduction effects of the designed TMDs on the high-pier bridge subject to actual earthquake samples are investigated and compared with that of using some other vibration absorption measures. Finally, a detailed train-track-bridge dynamic model with attached TMDs is established to study the effects of the designed TMDs on the seismic responses of the running trains. The results indicate that, for the high-pier T-beam bridges, the first bending vibration mode of the high-pier is most likely to be excited by earthquakes, which should be restrained. With the designed optimal parameters, the attached TMDs are effective to control seismic vibrations of the concerned high-pier bridges. Tuned mass damper is the best one among all the investigated measures to absorb vibrations subject to earthquakes from the perspective of vibration absorption performance, installation and maintenance. © 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group.","High-pier bridges; seismic effect; Sichuan–Tibet railway; TMD; train–track–bridge interaction; vibration reduction","Acoustic devices; Composite bridges; Earthquakes; Finite element method; Piers; Railroad bridges; Railroads; Vibration control; Design and construction; High piers; Installation locations; Seismic effect; Sichuan; Transportation system; Vibration reduction effects; Vibration reductions; Seismic design",,,,,"Southwest Jiaotong University, SWJTU; National Key Research and Development Program of China, NKRDPC: 2013CB036206","This work was supported by the National Basic Research Program of China (‘973’ Program) [grant number 2013CB036206]; and the open research fund of MOE Key Laboratory of High-speed Railway Engineering, Southwest Jiaotong University.",,,,,,,,,,"(2013), Report on the Evaluation of Fault Activity along the Lhasa—Nyingchi Section Project of the Chuanzang Railway and the Regionalization of Ground Oscillation Parameters, Chinese; Ormondroyd, J., Theory of the dynamic vibration absorber (1928) Trans ASME, 50, pp. 9-22; Hahnkamm, E., Die dämpfung von fundamentschwingungen bei veränderlicher erregerfrequenz (1933) Arch Appl Mech, 4 (2), pp. 192-201; Brock, J.E., A note on the damped vibration absorber (1946) J Appl Mech, 13 (4); Den, H.J.P., (1956) Mechanical vibrations, , 4th ed., Mississauga: McGraw-Hill; Domaneschi, M., Martinelli, L., Po, E., Control of wind buffeting vibrations in a suspension bridge by TMD: hybridization and robustness issues (2015) Comput Struct, 155, pp. 3-17; Xing, C., Wang, H., Li, A., Study on wind-induced vibration control of a long-span cable-stayed bridge using TMD-type counterweight (2013) J Bridge Eng, 19 (1), pp. 141-148; Wang, J.F., Lin, C.C., Chen, B.L., Vibration suppression for high-speed railway bridges using tuned mass dampers (2003) Int J Solids Struct, 40 (2), pp. 465-491; Li, J., Su, M., Fan, L., Vibration control of railway bridges under high-speed trains using multiple tuned mass dampers (2005) J Bridge Eng, 10 (3), pp. 312-320; Villaverde, R., Reduction seismic response with heavily-damped vibration absorbers (1985) Earthquake Eng Struct Dyn, 13 (1), pp. 33-42; Martínez-Rodrigo, M.D., Filiatrault, A., A case study on the application of passive control and seismic isolation techniques to cable-stayed bridges: A comparative investigation through non-linear dynamic analyses (2015) Eng Struct, 99, pp. 232-252; Zhu, S., Yang, J., Yan, H., Low-frequency vibration control of floating slab tracks using dynamic vibration absorbers (2015) Vehicle Syst Dyn, 53 (9), pp. 1296-1314; Zhai, W., Xia, H., Cai, C., High-speed train–track–bridge dynamic interactions–part I: theoretical model and numerical simulation (2013) Int J Rail Transport, 1 (1-2), pp. 3-24; Zhuang, J.S., (2012) Bridge isolation bearings and devices, , Beijing: China Railway Publishing House; Frýba, L., Non-stationary response of a beam to a moving random force (1976) J Sound Vib, 46 (3), pp. 323-338; Chen, Z., Zhai, W., Cai, C., Safety threshold of high-speed railway pier settlement based on train-track-bridge dynamic interaction (2015) Sci China Tech Sci., 58 (2), pp. 202-210; Yang, Y.B., Lin, B.H., Vehicle-bridge interaction analysis by dynamic condensation method (1995) J Struct Eng, 121 (11), pp. 1636-1643; Zhai, W., Wang, S., Zhang, N., High-speed train–track–bridge dynamic interactions–part II: experimental validation and engineering application (2013) Int J Rail Transport, 1 (1-2), pp. 25-41; Chen, Z., Zhai, W., Yin, Q., Analysis of structural stresses of tracks and vehicle dynamic responses in train–track–bridge system with pier settlement (2018) Proc Inst Mech Eng F: J Rail Rapid Transit, 232 (2), pp. 421-434; Chen, Z., Zhai, W., Tian, G., Study on the safe value of multi-pier settlement for simply supported bridges in high-speed railways (2018) Struct Infrastruct Eng, 14 (3), pp. 400-410; Zhai, W.M., Two simple fast integration methods for large-scale dynamic problems in engineering (1996) Int J Numer Methods Eng, 39 (24), pp. 4199-4214","Chen, Z.; School of Mechanotronics and Vehicle Engineering, China; email: chenzhaowei@my.swjtu.edu.cn",,,"Taylor and Francis Ltd.",,,,,00423114,,VSDYA,,"English","Veh Syst Dyn",Article,"Final","",Scopus,2-s2.0-85044939690

By comprehensively considering the uncertainties in ground motion and structural parameters, a large-sample analysis method for near-faults area was proposed. In addition, an integrated finite element model for beam bridge-track system of high-speed railway was used to calculate the seismic response of the structure under the action of near-fault ground motion. The over-limit state and applicability of seismic response of key components and systems were predicted and evaluated. The analysis results indicate that the statistical characteristics of structural seismic response and over-limit state tend to be stable with increasing number of samples. Under the near-fault ground motion: (i) the piers of high-speed railway are hard to yield (ii) bearings are damaged severely, and (iii) the piers have insufficient shear capacity and the characteristics of structural seismic damage are not in accordance with the concept of ductility design. The sliding layer of the track structure is severely damaged by the transverse and longitudinal ground motions, while the CA mortar layer and fastener are mainly damaged by the transverse ground motion. The applicability of bearings, the anti-shearing behavior of piers, and the inter-layer structure of tracks make it difficult to achieve the goal of the near-fault fortification against ground motion. © 2020 Elsevier Ltd","Applicability; High-speed railway; Near-fault ground motion; Track system","Bridges; Piers; Railroads; Seismic design; Seismic response; Structural analysis; Uncertainty analysis; Applicability analysis; High - speed railways; High-speed railway systems; Large sample analysis; Near fault ground motion; Seismic design method; Statistical characteristics; Structural seismic response; Railroad transportation; bridge; earthquake engineering; finite element method; ground motion; high-speed train; railway; seismic design; seismic response; structural analysis",,,,,"2019RS3009; National Natural Science Foundation of China, NSFC: 51778630, U1934207","The research described in this study was financially supported by the National Natural Science Foundation of China ( 51778630 , U1934207 ), and the Hunan Innovative Provincial Construction Project ( 2019RS3009 ).",,,,,,,,,,"Meng, L., Zhou, L., Liu, J., Source parameters of the 2013 Lushan MS7.0 earthquake and the characteristics of the near-fault strong ground motion (2013) Acta Seismol Sin, 35, pp. 632-641; Wei, T., Zhao, F., Zhang, Y., Characteristics of near-fault ground motion containing velocity pulses (2006) Earthq Sci, 19, pp. 677-686; Xie, J.J., Wen, Z.P., Gao, M.T., Hu, Y.X., He, S.L., Characteristics of near-fault vertical and horizontal ground motion from the 2008 wenchuan earthquake (2010) Chin J Geophys, 53, pp. 555-565; Zhang, J., Tang, Y., Dimensional analysis of structures with translating and rocking foundations under near-fault ground motions (2009) Soil Dynam Earthq Eng, 29, pp. 1330-1346; Maniatakis, C.A., Spyrakos, C.C., A new methodology to determine elastic displacement spectra in the near-fault region (2012) Soil Dynam Earthq Eng, 35, pp. 41-58; Dreger, D., Hurtado, G., Chopra, A., Larsen, S., Near-Field across-fault seismic ground motions (2011) Bull Seismol Soc Am, 101, pp. 202-221; Jónsson, M.H., Bessason, B., Haflidason, E., Earthquake response of a base-isolated bridge subjected to strong near-fault ground motion (2010) Soil Dynam Earthq Eng, 30, pp. 447-455; Gillie, J.L., Rodriguez-Marek, A., Mcdaniel, C., Strength reduction factors for near-fault forward-directivity ground motions (2010) Eng Struct, 32, pp. 273-285; Dutta, S.C., Kunnath, S.K., Effect of bidirectional interaction on seismic demand of structures (2013) Soil Dynam Earthq Eng, 52, pp. 27-39; Moustafa, A., Takewaki, I., Deterministic and probabilistic representation of near-field pulse-like ground motion (2010) Soil Dynam Earthq Eng, 30, pp. 412-422; Zhang, S., Wang, G., Effects of near-fault and far-fault ground motions on nonlinear dynamic response and seismic damage of concrete gravity dams (2013) Soil Dynam Earthq Eng, 53, pp. 217-229; Billah, A.H.M.M., Alam, M.S., Bhuiyan, M.A.R., Fragility analysis of retrofitted multicolumn bridge bent subjected to near-fault and far-field ground motion (2013) J Bridge Eng, 18, pp. 992-1004; Dicleli, M., Buddaram, S., Equivalent linear analysis of seismic-isolated bridges subjected to near-fault ground motions with forward rupture directivity effect (2007) Eng Struct, 29, pp. 21-32; Dicleli, M., Supplemental elastic stiffness to reduce isolator displacements for seismic-isolated bridges in near-fault zones (2007) Eng Struct, 29, pp. 763-775; China, (2009) The code for seismic design of railway engineering, GB50111-2006, , M.O.R.

The rail is represented by an infinite Timoshenko beam connected to the sleepers which are regarded as finite Timoshenko beams supported in ballast. The fasteners and ballast are simplified as a series of springs with complex stiffness. This model allows the receptance of the track to be determined. The wheel-rail forces are computed in the frequency domain from the contact-filtered roughness and the receptances of the wheel, track, and contact. The forces transmitted to the bridge are determined by substituting the wheel-rail forces into the equation of motion for the track. This model could also be applied to a slab track mounted on a bridge. A hybrid FE-SEA method is introduced in which FE is used to model the concrete deck and SEA is used to model the steel girders. This enables the computation of the vibration and noise of the composite railway bridge. The proposed method is verified by comparing its predictions with field measurements. The structure-borne noise level of the bridge is found to increase with train speed v by approximately 20lg(v). It is shown that the adjacent spans in a multi-span bridge can be ignored in deriving the bridge-borne noise at receiver points in the middle of the main span, provided that the distance to the track centreline is less than 0.3 times the length of the main span. © 2020 Elsevier Ltd","Composite bridge; Geometrical attenuation; Hybrid FE-SEA method; Sound contribution; Structure-borne noise","Ballast (railroad track); Composite bridges; Energy management; Equations of motion; Finite element method; Frequency domain analysis; Particle beams; Railroad bridges; Railroad tracks; Railroad transportation; Railroads; Rails; Vehicle wheels; Vibration analysis; Geometrical attenuation; Hybrid FE-SEA methods; Hybrid finite elements; Sound contributions; Statistical energy analysis; Statistical energy analysis methods; Steel-concrete composite; Structure-borne noise; Concretes",,,,,"University of Southampton; National Natural Science Foundation of China, NSFC: 51608201, 51878277, 51878565; China Scholarship Council, CSC; Education Department of Jiangxi Province: GJJ 180295","This work was supported by the National Natural Science Foundation of China (grant numbers 51608201, 51878277 and 51878565), the Education Department of Jiangxi Province, China (grant number GJJ 180295) and the China Scholarship Council.

From previous studies, it was found that the welded joint between the box girder diagonal and the central hanger gusset is one of the most stressed details of the bridge. This welded joint was not fully manufactured according to current construction procedures, as regards the fillet weld end configuration. In order to assess the fatigue behaviour of such welded joint, the present study combines an experimental campaign and numerical analysis. A total of four welded joint series were produced in order to allow the comparison of the fatigue performance of similar type of welded joint of the Alcácer do Sal bridge with welded joints produced according to existing recommendations, such as EC3. Since scale-down specimens were considered, two different thicknesses were included in this study for each joint configuration, to allow the verification of any thickness effect. Concerning the numerical analyses, two main numerical tools were used: the standard Finite Element Method (FEM) with ANSYS and the eXtended Finite Element Method (XFEM) with ABAQUS. Fatigue life predictions were performed including both fatigue crack initiation and fatigue crack propagation phases. The number of cycles to initiate a fatigue crack was computed using local notch strain-life approaches, and the number of cycles for fatigue crack propagation was computed by integrating the Paris fatigue crack growth law with stress intensity factors computed with ANSYS (virtual crack closure technique) and ABAQUS (contour integral method, 3D XFEM model). Experimental tests demonstrated little influence of fillet weld end geometry on fatigue behaviour of welded joints and plate thickness effects were also reduced as also confirmed by the similar fatigue crack propagation rates. Both numerical simulations provided very accurate predictions of the experimental S-N curves, however the XFEM modelling opens new possibilities for mix-mode fatigue crack propagation simulations. © 2019","Crack propagation; Extended Finite Element Method; Fatigue assessment; Fillet welded joints; Finite Element Method; Local strain-life approach","ABAQUS; Box girder bridges; Crack closure; Crack propagation; Fatigue crack propagation; Finite element method; Numerical methods; Welded steel structures; Welding; Welds; Extended finite element method; Fatigue assessments; Fatigue crack growth law; Fatigue crack initiation; Fatigue crack propagation rate; Fillet welded joint; Local strains; Virtual crack closure technique; Fatigue of materials",,,,,"Fundação para a Ciência e a Tecnologia, FCT; Federación Española de Enfermedades Raras, FEDER; Research Fund for Coal and Steel, RFCS: RFSR-CT-2009-00027, SFRH/BD/72434/2010, SFRH/BPD/107825/2015; Institute of Research and Development in Structures and Construction","This work was financially supported by: Projects POCI-01-0145-FEDER-007457 and UID/ECI/04708/2019 - CONSTRUCT - Institute of R&D In Structures and Construction funded by FEDER funds through COMPETE2020 - Programa Operacional Competitividade e Internacionalização (POCI) – and by national funds through FCT - Fundação para a Ciência e a Tecnologia ; RFCS Project called FADLESS - Fatigue Damage Control and Assessment for Railway Bridges (RFSR-CT-2009-00027); Ph.D. Scholarship (SFRH/BD/72434/2010) provided by FCT to the first author; and post-doctoral grant SFRH/BPD/107825/2015 provided by FCT to the second author.

An orthogonal compound bridge-type amplifier is introduced to amplify the displacement of the PEA. It significantly reduces the height of the stage and leads to a compact design. By analytical modeling of the mechanism, the design variables are determined, which are then optimized via the multiobjective genetic algorithm based on the finite-element analysis. Simulation results show that the 1-DOF stage is able to provide the maximum displacement of 181.18~\mu \text{m} in theory, which is more than 12\times the input displacement of PEA. Payload test results indicate that the stage can support a maximum load of about 80 N. Comparison study reveals that the presented vertical positioning stage offers a more compact structure than existing ones. A prototype is fabricated for experimental studies, and the deviation between the experimental and simulation results is discussed in detail. Moreover, closed-loop performance test exhibits a resolution of 10 nm for the developed vertical positioning stage. Note to Practitioners - The motivation of this paper is to devise a compact flexure-based stage, which can be mounted on the top of an XY stage for constructing a hybrid type of XYZ stage dedicated to micro/nanopositioning applications. Such a design scheme provides a more flexible solution than serial- and parallel-kinematic designs. In order to fulfill the design requirement and to improve the compactness and output directionality of the stage, a series of design processes is conducted. The design parameters are optimized and the optimal design leads to the stage dimension of 58 mm \times20 mm \times15.5 mm (length \times width \times height), which offers a motion range of 97.32~\mu \text{m} as verified by the experimental study. In consideration of the motion range and physical size, the proposed stage offers a more compact structure than available designs. Experimental results demonstrate the fine performance of the developed prototype stage for vertical micro/nanopositioning. © 2004-2012 IEEE.","Compliant mechanism; flexure stage; mechanism design; micro/nanopositioning; piezoelectric actuator (PEA)","Analytical models; Compliant mechanisms; Degrees of freedom (mechanics); Fabrication; Genetic algorithms; Machine design; Mechanisms; Optimization; Piezoelectricity; Springs (components); Testing; Closed-loop performance; Flexure stages; Force; Maximum displacement; Mechanism design; micro/nanopositioning; Multi-objective genetic algorithm; One degree of freedom (1-DOF); Piezoelectric actuators",,,,,"MYRG2018-00034-FST; National Natural Science Foundation of China, NSFC: 51575545; Fundo para o Desenvolvimento das Ciências e da Tecnologia, FDCT: 179/2017/A3","Manuscript received April 26, 2018; revised September 7, 2018; accepted October 7, 2018.

CFSST columns can be used for bridge piers, multi-story buildings and other supporting structures. However, a common mode of failure with these type of tubular composite columns is inelastic outward local buckling occurring at the column ends. Therefore, this paper presents the results of experimental, numerical and analytical investigations into the behavior of circular CFSST columns strengthened by carbon fiber reinforced polymer (CFRP) wrap and subjected to axial compression loading. The experimental investigation comprised three series of tests. The main variables tested were the diameter to thickness ratio of the stainless steel tube and the thickness of the CFRP wrap. 3D finite element models (FEMs) were developed for CFRP-wrapped CFSST columns using the ABAQUS software and were validated with experimental results. An extensive parametric study was carried out by using the validated FEMs. It was shown from the experimental and FEMs results that CFRP jacketing was highly effective in improving the axial load carrying capacity and axial shortening capacity of the CFSST columns. Finally, an analytical model based on the FE parametric study results was proposed to predict the axial load carrying capacity of the CFRP-wrapped CFSST columns. © 2019 Elsevier Ltd","Analytical model; Carbon fiber reinforced polymer; Concrete-filled stainless steel tubes; Experimental work; Finite element analysis; Stainless steel","ABAQUS; Analytical models; Axial loads; Beams and girders; Carbon fiber reinforced plastics; Columns (structural); Fiber reinforced plastics; Filled polymers; Finite element method; Load limits; Reinforced concrete; Reinforced plastics; Reinforcement; Steel fibers; Structural analysis; Tubular steel structures; 3D finite element model; Analytical investigations; Carbon fiber reinforced polymer; Carbon fiber reinforced polymer wraps; Diameter-to-thickness ratios; Experimental investigations; Experimental work; Stainless steel tube; Stainless steel; column; concrete structure; experimental study; finite element method; performance assessment; polymer; steel structure; structural analysis",,,,,"King Fahd University of Petroleum and Minerals, KFUPM; Deanship of Scientific Research, King Saud University: IN161047","This research work was funded by the Deanship of Scientific Research in King Fahd University of Petroleum and Minerals (KFUPM), Saudi Arabia.

The learning process of neural network can be more robust when presented in the Bayesian framework, and rational architecture of the Bayesian neural network is critical to its performance. Apart from number of hidden neurons, the specific forms of the transfer functions in both hidden and output layers are also crucially important. To the best of our knowledge, however, the simultaneous design of proper number of hidden neurons, and specific forms of hidden- and output-layer transfer functions has not yet been reported in terms of the Bayesian neural network. It is even more challenging when the transfer functions of both layers are parameterized instead of using fixed shape forms. This paper proposes a tailor-made algorithm for efficiently designing the appropriate architecture of Bayesian neural network with simultaneously optimized hidden neuron number and custom transfer functions in both hidden and output layers. To cooperate with the proposed algorithm, both the Jacobian of the network function and Hessian of the negative logarithm of weight posterior are derived analytically by matrix calculus. This is much more accurate and efficient than the finite difference approximation, and also vital for properly designing the Bayesian neural network architecture as well as further quantifying the confidence interval of network prediction. The validity and efficiency of the proposed methodology is verified through probabilistic finite element (FE) model updating of a pedestrian bridge by using the field measurement data. © 2019 Computer-Aided Civil and Infrastructure Engineering",,"Calculations; Closed loop control systems; Finite difference method; Footbridges; Multilayer neural networks; Neurons; Structural health monitoring; Transfer functions; Architecture designs; Bayesian neural networks; Field measurement data; Finite difference approximations; Number of hidden neurons; Probabilistic finite elements; Structural model updating; Structural system identification; Network architecture; algorithm; architectural design; artificial neural network; Bayesian analysis; finite element method",,,,,"University of Liverpool; National Natural Science Foundation of China, NSFC: 51778506, 51838006; China Scholarship Council, CSC: 201806275091","The authors gratefully acknowledge the financial support provided by the National Natural Science Foundation of China (Grant Nos. 51778506, 51838006), and a scholarship from the China Scholarship Council (Grant No. 201806275091) while the first author was visiting the Center for Engineering Dynamics and Institute for Risk and Uncertainty in the University of Liverpool.

The netting theory was employed to design the lay-up of the cylindrical section. For precise prediction of the dome thickness, a cubic spline function was utilized. Variable polar radii were used to reduce the fiber stacking and thickness accumulation near polar openings. To evaluate the designed lay-up, various failure criteria were applied so as to predict precisely the failure of composite layers in finite element analysis. In order to determine the most appropriate range of the internal pressure when filling hydrogen gas during filament winding process, the compressive pressure applied on the liner was calculated by taking into account the variety of winding tension, and the buckling and static analysis of the liner were carried out, respectively. The methods presented in this work provide a valuable reference for designing the type IV hydrogen storage vessels. © 2020 Elsevier Ltd","Composite material; Filament winding; Type IV hydrogen vessel; Variable polar radii; Winding tension","Bridge decks; Composite materials; Domes; Failure (mechanical); Forecasting; Hydrogen storage; Interpolation; Compressive pressure; Cubic spline functions; Filament winding process; Hydrogen storage vessels; Hydrogen vessels; Thickness distributions; Variable polar radii; Winding tension; Filament winding",,,,,"2019YFB1504800; National Natural Science Foundation of China, NSFC: 51875159; Natural Science Foundation of Beijing Municipality: 2192044; Fundamental Research Funds for the Central Universities: PA2019GDPK0051, XK1802-2; Key Research and Development Program of Jiangxi Province: 201904d07020013","This research is supported by the National Natural Science Foundation of China (Grant No. 51875159), the National Key Research and Development Project (No. 2019YFB1504800), the Beijing Natural Science Foundation (Grant No. 2192044), the Key Research and Development Program of Anhui Province (Grant No. 201904d07020013), the Fundamental Research Funds for the Central Universities (Grant No. XK1802-2, PA2019GDPK0051).

This paper develops a methodology for assessing time-variant reliability and redundancy of multigirder prestressed concrete bridges at material, component, and system levels. Nonlinear analysis was performed to obtain the constitutive relationship of reinforced sections and girder components in which the adverse effects of reinforcement corrosion on structural capacity and ductility are considered. Subsequently, the nonlinear finite-element analysis was conducted to capture the time-dependent probabilistic resistance of the bridge system, considering different failure criteria (e.g., serviceability and ultimate limit states). Given the component- and system-level performance indicator, structural capacity-, reliability- and risk-informed redundancy was assessed. The feasibility and capability of the proposed approach were illustrated using an existing prestressed concrete bridge. The results demonstrate that the integrated damage mechanism between different levels has a significant effect on the structural ultimate capacity, reliability, and redundancy of corroded structures. © 2019 American Society of Civil Engineers.","Ductility; Nonlinear finite element; Redundancy; Reinforcement corrosion; Reliability; Risk; System-level performance","Concrete beams and girders; Concrete bridges; Deterioration; Ductility; Electrochemical corrosion; Nonlinear analysis; Prestressed concrete; Reinforcement; Reliability; Risk assessment; Risks; Constitutive relationships; Non-linear finite elements; Non-linear finite-element analysis; Reinforcement corrosion; Structural deterioration; System-level performance; Time dependent reliability; Time-variant reliability; Redundancy",,,,,,,,,,,,,,,,"(2007) LRFD Bridge Design Specifications, 4th Ed., , AASHTO.

In this paper, ECC material was proposed to be applied on the long-span steel bridge deck overlay. Herein we studied the feasibility of this application via integration of ECC’s material performances and stress response of structure using finite element analysis. The results show that ECC material could overcome the brittleness of normal concrete, featuring high tensile strain/deformability capacity under tension/flexural load, as well as higher flexural strength and fatigue life, compared with normal asphalt/concrete materials. Furthermore, the self-healing capacity in ECC helps the crack seal itself, as a result, recovers its water permeability coefficient and resistance to chloride ion penetration to nearly the same level as undamaged ones. By integrating ECC’s flexural fatigue behaviour and finite element analysis, it can be concluded that ECC is feasible to be a candidate material for the steel bridge overlay. The application of ECC is expected to greatly extend the service life of steel bridge overlay meanwhile be with thinner thickness compared with normal bridge deck overlay structure, resulting in a more sustainable overlay. © 2017, © 2017 Informa UK Limited, trading as Taylor & Francis Group.","ECC material; fatigue life; finite element analysis; self-healing; steel bridge deck overlay","Bridge decks; Chlorine compounds; Finite element method; Fracture mechanics; Self-healing materials; Steel bridges; Tensile strain; Candidate materials; Chloride ion penetration; Engineered cementitious composite (ECC); Feasibility studies; Material performance; Normal concretes; Overlay structures; Self-healing; Fatigue of materials",,,,,"University of Michigan, U-M; National Natural Science Foundation of China, NSFC: 51278097; Fundamental Research Funds for the Central Universities: 106112017CDJQJ208849, 106112017CDJXY200011","This study was supported by the Fundamental Research Funds for the Central Universities [grant number 106112017CDJXY200011, 106112017CDJQJ208849] and the National Natural Science Foundation of China [grant number 51278097] for the financial support for this work.","This study was supported by the Fundamental Research Funds for the Central Universities [grant number 106112017CDJXY200011, 106112017CDJQJ208849] and the National Natural Science Foundation of China [grant number 51278097] for the financial support for this work.

In order to bridge this knowledge gap, this study presents a practical approach to overcome fire hazard in steel bridges of critical nature. The proposed approach comprises of two components namely, analytical and numerical. In the analytical component, fire risk in a steel bridge is assessed, through a specially derived fire-based importance factor that allows estimating vulnerability of a bridge to fire hazard. The second component integrates both simplified calculation method as well as highly nonlinear numerical analysis through a coupled finite element (FE) based simulation with the purpose of developing relevant strategies for mitigating fire risk and losses. The applicability of this approach is illustrated herein through a comprehensive case study on an actual steel bridge that underwent an intense fire incident. The aim of this study is first to present engineers and designers with a practical tool to identify steel bridges vulnerable to fire hazard and secondly to guide them into developing optimum solutions to mitigate large fire losses. © 2019 Elsevier Ltd","Bridges; Design and Mitigation strategies; Finite element simulation; Fire hazard","Bridges; Finite element method; Fire hazards; Numerical methods; Risk assessment; Risk perception; Steel bridges; Current codes; Finite element simulations; Importance factors; Knowledge gaps; Mitigation strategy; Nonlinear numerical analysis; Optimum solution; Simplified calculation method; Fire resistance",,,,,"National Science Foundation, NSF: CMMI-1068621; Michigan State University, MSU","This material is based upon the work supported by the National Science Foundation under Grant number CMMI-1068621 and Michigan State University.

The drop-hammer impact tests were performed to investigate the response of the composite structure composed of UHPFRC panels and the energy-absorbing member of corrugated steel tubes. For all test specimens, the expected damage modes were observed during impact testing. Specifically, the energy-absorbing member experienced large deformation to dissipate the kinetic energy of drop hammer, while slight damages occurred in the UHPFRC panels directly contacted with a drop hammer. Also, the impact tests showed that the impact force was more sensitive to the number of corrugated tubes than the tube thickness. On the contrary, increasing the tube thickness more effectively improved the energy dissipation capacity of the structure than adding the number of corrugated steel tubes. A finite element (FE) modeling method considering manufacturing process was proposed and demonstrated to be capable of capturing the impact-induced response of UHPFRC-based composite structures. Comparisons between the experimental data and the numerical results highlighted the importance of including the influence of the manufacturing process in modeling corrugated steel tubes. Using the validated FE modeling method, two types of UHPFRC-based protective structures were investigated and compared. Results showed that the protective structure with disconnection details between inner and outer panels was superior to that with connection details. The advantages of the former one included more effective reductions of the impact force and damage in UHPFRC panels for the reuse to improve the economy. Finally, a multi-objective optimization design procedure was presented to find the optimum configuration of the proposed protective structures under vehicle collisions. © 2020 Elsevier Ltd","Drop-hammer impact test; FE modeling; Multi-objective optimization; Protective structure; Ultra-high performance fiber reinforced concrete (UHPFRC); Vehicle collision","Drops; Energy absorption; Energy dissipation; Fiber reinforced materials; Hammers; High performance concrete; Impact testing; Kinetic energy; Kinetics; Manufacture; Multiobjective optimization; Reinforced concrete; Structure (composition); Tubes (components); Tubular steel structures; Vehicle performance; Drop hammers; FE model; Protective structures; Ultra-high-performance fiber-reinforced concrete; Vehicle collisions; Structural optimization; bridge; collision; column; computer simulation; experimental study; finite element method; impact; numerical model; optimization; reinforced concrete",,,,,"2019AC20136; National Natural Science Foundation of China, NSFC: 51978258; National Key Research and Development Program of China, NKRDPC: 2018YFC0705400; Science and Technology Program of Hunan Province: 2017SK1010","This research is supported by the National Key Research and Development Program of China (Grant Number: 2018YFC0705400 ), the National Natural Science Foundation of China (Grant Number: 51978258 ), the Major Program of Science and Technology of Hunan Province (Grant Number: 2017SK1010 ), and the Science and Technology Base and Talent Special Project of Guangxi Province (Grant Number: 2019AC20136 ).","This research is supported by the National Key Research and Development Program of China (Grant Number: 2018YFC0705400), the National Natural Science Foundation of China (Grant Number: 51978258), the Major Program of Science and Technology of Hunan Province (Grant Number: 2017SK1010), and the Science and Technology Base and Talent Special Project of Guangxi Province (Grant Number: 2019AC20136).",,,,,,,,,"Wardhana, K., Hadipriono, F.C., Analysis of recent bridge failures in the United States (2003) J Perform Constr Facil, 17, pp. 144-150; Xu, X., Performance Based Approach for Loading and Design of Bridge Piers Impacted by Medium Weight Trucks, in (2017), The City College of New York New York; Buth, C.E., Williams, W.F., Brackin, M.S., Lord, D., Geedipally, S.R., Abu-Odeh, A.Y., (2010), Analysis of Large Truck Collisions with Bridge Piers: Phase 1, Report of Guidelines for Designing Bridge Piers and Abutments for Vehicle Collisions.

The vehicle plays two roles: that of the measurement device and that of the excitation source. Permanent changes to the bridge's stiffness due to damage or wear may manifest as changes in the bridge's fundamental frequencies. In vehicle-based inspection, bridge frequencies are extracted from vehicle responses. These bridge frequencies may be estimated periodically as a continuing bridge condition assessment. This paper establishes closed-form solutions for bridge and vehicle vibration as a vehicle traverses a two-span continuous bridge and provides a method of bridge frequency extraction from vehicle response. Results are validated using finite-element simulations and compared against the literature. Results show that bridge frequencies observed by the vehicle manifest as two peaks shifted below and above the fundamental bridge frequency. These shifts are linear functions and the average of these shifted bridge frequencies approximates the fundamental bridge frequency to within 7% error; this error decreases to 2% for equal spans. © 2019 American Society of Civil Engineers.","Dynamic response; Moving vehicle load; Multispan continuous bridge; Vehicle-based bridge inspection; Vehicle-bridge interaction","Bridges; Dynamic response; Frequency estimation; Inspection; Structural health monitoring; Vehicles; Bridge inspection; Closed form solutions; Condition assessments; Continuous bridges; Finite element simulations; Fundamental frequencies; Moving vehicle load; Vehicle-bridge interaction; Vibrations (mechanical); bridge; dynamic response; estimation method; finite element method; frequency analysis; structural response; vibration",,,,,,,,,,,,,,,,"Arangio, S., Bontempi, F., Soft computing based multilevel strategy for bridge integrity monitoring (2010) Comput.-Aided Civ.

On monopiles to achieve a GC, tubular hollow steel piles are in-situ attached with a high-strength grout. Monopiles are susceptible to large magnitude bending loads in offshore environments. Recently, following inspections the performance of GCs has been called into doubt when settlements were reported on several monopiles. To further comprehend the structural performance of GCs under large bending moments a nonlinear Finite Element (FE) analysis was conducted. Three-dimensional FE models were solved and validated against experimental and analytical data with good agreement. It is suggested that the presented models can be used to evaluate the global and local behaviour of a GC accurately. Finally, a comprehensive parametric study was carried out to investigate the influence of shear key numbers, shear key spacing and overlap lengths. It was shown that increased number of shear keys are advantageous for stiffness and reduce the gap at the interfaces, whereas the grout failure depends on the spacing between neighbouring shear keys. The ability of the numerical model to trace all relevant failure modes which are provoked by shear key spacing was also demonstrated. © 2018 Elsevier Ltd","Finite element analysis; Grouted connections; High-strength grout; Monopile; Offshore wind turbines; Shear keys","Bridge decks; Concrete construction; Grouting; Mortar; Offshore oil well production; Offshore wind turbines; Grouted connection; High strength; Large bending moments; Monopile; Non-linear finite-element analysis; Offshore environments; Shear key; Structural performance; Finite element method; bending; finite element method; grouting; parameterization; pile; shear; steel; wind turbine",,,,,"Alexander von Humboldt-Stiftung; European Cooperation in Science and Technology, COST; Gottfried Wilhelm Leibniz Universität Hannover, LUH","The authors would like to acknowledge the Birmingham Environment for Academic Research (BlueBEAR) for providing the computational resources for this work.

A novel and critical discussion of composite damage modelling techniques used in machining works is offered, yielding numerous insights; advantages and disadvantages of current numerical techniques as well as possible improvements are included. Additionally, computational findings achieved so far in the literature are analysed in detail to allow remark of the current scope in the machining of LFRP laminates. Despite ingenious numerical solutions having been generated by previous authors to face the complex problems involve with the simulation of composite machining, the numerical capabilities to model the machining induced damage are still limited. Hence, different numerical strategies should be considered in future computational studies to enhance the reliability of current finite element models. The use of advanced continuum damage mechanics (CDM) approaches inserted via user-defined subroutines or the use of other computationally advanced methods such as eXtended Finite Element Method (XFEM) or phase field methods (PFM) to model composite fracture are recommended to improve the quality of numerical predictions. © 2020 Elsevier Ltd","Damage; Finite element; Fracture; Machining; Modelling","Bridge decks; Continuum damage mechanics; Damage detection; Fiber reinforced plastics; Fracture; Machining; Models; Numerical methods; Numerical models; Phase transitions; Polymers; Reinforcement; Computational studies; Damage; Extended finite element method; Fibre reinforced polymers; Fibre-reinforced polymer composites; Machining induced damage; Numerical predictions; Numerical strategies; Finite element method",,,,,"Engineering and Physical Sciences Research Council, EPSRC: EP/L016257/1; National Natural Science Foundation of China, NSFC: 11972146","This work was funded by the Engineering and Physical Sciences Research Council (EPSRC) institution with the grant EP/L016257/1 and a special mention is deserved to the Industrial Doctoral Centre (IDC) of Sheffield for their effective technical support in the development of this project.

These advantages can be listed as an aesthetically pleasing appearance, economic and easy construction, etc. The main structural elements of cable-stayed bridges are listed as deck, pylon, cables and foundation. Perhaps one of the most vital and expensive of these structural elements is stay-cables. Stay-cables ensure the allowable displacement and distribution of bending moments along the bridge deck with prestressing force. Therefore the optimum design of the stay-cables and prestressing force are very important in achieving the performance expected from the cable-stayed bridges. This paper aims to obtain the stay-cables size and prestressing force optimization of the cable-stayed bridge. For this purpose, single pylon and fan type cable configuration Manavgat Cable-Stayed Bridge was selected as an example. The three dimensional (3D) finite element model (FEM) of the bridge was created with SAP2000. Analysis of the 3D FEM of the bridge was conducted under the different combined effects of the self-weight of the structural element, prestressing force of stay-cable and live load. Stay-cable stress and deck displacement were taken into account as constraints for the optimization problem. To optimize this existing bridge a metaheuristic algorithm named Jaya was used in the optimization process. 3D FEM of the selected bridge was repeatedly analyzed by using Open Applicable Programming Interface (OAPI) properties of SAP2000. To carry out the optimization process the developed program which integrates the Jaya algorithm and the required codes for calling SAP2000 is coded in MATLAB. At the end of the study, the total weight of the stay-cables was reduced more than 40% according to existing stay cables under loads taken into account.

A compressive test condition was used to model the mortar cracks under compression loading. Mortar samples with dimension of 100 mm × 50 mm × 50 mm were prepared. The length of joints was 2 cm. In experimental tests, the joint number is 1, 2 and 3 and its angularities change from 0° to 90° with increment of 45°. Assuming a plane strain condition, special rectangular models are prepared with dimension of 100 mm × 50 mm. Similar to joints configuration in experimental test, 9 models with different joint number and joint angularities were prepared. Also numerical Brazilian test was simulated with the same joint number and joint angularity. The results show that the failure process is mostly governed by the joint number and joint angularities. The both of the compression strengths and tensile strength of the specimens are related to the fracture pattern and failure mechanism of the discontinuities. The strength of samples decreases by increasing the joint number and joint angularities. Failure pattern and failure strength are nearly similar in both of the experimental test and numerical simulation. © 2019 Elsevier Ltd","Compressive test; Joint angularities; Joint number; XFEM","Compressive strength; Mortar; Strain; Tensile strength; Compression loading; Compression strength; Compressive tests; Experimental simulations; Experimental test; Failure mechanism; Fracture pattern; XFEM; Failure (mechanical)",,,,,,,,,,,,,,,,"Abdelaziz, Y., Hamouine, A., A survey of the extended finite element (2008) Comput.

To guarantee the imaging quality of the system, each segment needs to be aligned at micron-level precision with millimeter-level range. For this purpose, a PZT actuated six-axis high-precision positioning system, which consists of three serially connected parallel mechanisms is proposed in this article. Compared with previous 6-DOF positioning solutions, such as a Stewart platform, the proposed design features a relatively compact structure and straightforward kinematics. To realize long stroke and fine resolution simultaneously, bridge-type amplifiers are employed to enhance the stroke of the PZT actuation, and the flexure hinges are utilized to eliminate friction and backlash. The performance of the amplifier under two kinds of external loads are analyzed so that the amplifiers could be designed according to the application conditions. Furthermore, it can be found that the displacement sensors must be employed at the output end of the actuation module to eliminate the input coupling that commonly exists in the compliant mechanisms. The feasibility of the design is validated by finite-element analysis and experiment study. The maximum stroke is 2.1 mm in the Z-axis, and the finest resolution is 0.5 μm in X- and Y-axis. © 1996-2012 IEEE.","6-DOF positioning system; hybrid mechanism; piezoelectric actuators","Hinges; Mechanisms; Motion control; 6-DOF positioning; Compact structures; Displacement sensor; Fabrication Technologies; High precision positioning; Hybrid mechanisms; Parallel mechanisms; Stewart platforms; Piezoelectric actuators",,,,,"SKLRS201701A; National Natural Science Foundation of China, NSFC: 51475113, 51521003; Natural Science Foundation of Heilongjiang Province: E2015006; Project 211: B07018; Beijing Advanced Innovation Center for Intelligent Robots and Systems, Beijing Institute of Technology, BAICIRS: 2016IRS14","This work was supported in part by the National Natural Science Foundation of China under Grants 51475113 and 51521003, in part by the Natural Science Foundation of Heilongjiang Province under Grant E2015006, in part by the State Key Lab of Self-planned Project under Grant SKLRS201701A, in part by the Open Project of Advanced Innovation Center for Intelligent Robots and Systems under Grant 2016IRS14, and in part by the Programme of Introducing Talents of Discipline to Universities under Grant B07018.","Manuscript received August 16, 2018; revised February 13, 2019, May 15, 2019, and August 12, 2019; accepted September 16, 2019.

Despite these types of bridges have shown an appropriate behavior under the influence of gravity (vertical) loads, they have not been designed seismically. Concerning to the seismic hazard zoning map of Iran, most of these railway infrastructures are placed in the very high seismicity zones and constructed near the major faults. So the seismic assessment of these types of bridges has become a significant subject for the engineers to explain the failure and seismic performance levels of these structures. Thus, they can be rehabilitated or removed if it is found required. Among various methods for seismic estimation of the capacity of the structures under seismic loading, the non-linear dynamic method or the incremental dynamic analysis (IDA) may be mentioned as the most precise and complete method for near-field excitations. For this purpose, by selecting 28 near-field earthquake records, this study has seismically surveyed two railway masonry arch bridges, which are respectively placed in the kilometers 23 (2L20 bridge) and 24 (5L06 bridge) of the old railway of Tehran-Qom. The macro-modeling approach was used in the finite element method. In total, 316 non-linear dynamic analyses have been carried out for the seismic assessment of the masonry arch bridges under near-field ground motion. The results found from the IDA analysis specified that the near-field seismic performance of the masonry arch bridge with lower span length (i.e., 5L06 bridge) is safer than the bridge with longer span length (i.e., 2L20 bridge). Mostly, it has to decide to retrofit the masonry bridge with longer span length to improve their performance since the seismic behavior of those has been found inappropriate under near-field earthquakes. © 2019","Finite element model; Incremental dynamic analysis (IDA); Masonry arch bridges; Near-field ground motion; Seismic performance","Arches; Concretes; Earthquake effects; Earthquake engineering; Finite element method; Maps; Masonry bridges; Masonry construction; Railroad transportation; Railroads; Seismic response; Seismic waves; Incremental dynamic analysis; Masonry arch bridges; Near field ground motion; Near-field earthquakes; Non-linear dynamic analysis; Railway infrastructure; Seismic Performance; Seismic performance assessment; Arch bridges",,,,,,,,,,,,,,,,"Heyman, J., The Masonry Arch (1982); Fanning, P.J., Boothby, T.E., Three-dimensional modelling and full-scale testing of stone arch bridges (2001) Comput.

Field load testing of old railway bridges in km-23 and km-24 of Tehran–Qom railway have revealed important characteristics of the bridges and have proven that there is still a large capacity under service load. Since most of these bridges are not designed for earthquake excitation, seismic vulnerability of these structures is uncertain. This fact necessitates the investigation of the earthquake resistance of these kinds of bridges. In this paper, seismic performance of bridges is assessed by the pushover analysis. These bridges are plain concrete arch structures with different span length and mechanical properties which have been built 70 years ago. The results of dynamic load tests are used to calibrate a finite element model of the bridges in which a plain strain analysis is carried out. Using non-linear static analysis method, suggested by several modern standards, the capacity curves of the structures and non-linear demand spectrum are obtained. The choice of control nodes in the pushover analysis and their influences on seismic performance of plain concrete arch bridges are investigated. The crown, centre of mass and a virtual point are selected as control nodes and it is demonstrated that the capacity curves are almost identical in all control node cases. Finally, the demand levels of the bridges are determined and compared with capacity curves. The results show that the earthquake resistance of these kinds of bridges totally depends on material properties and geometry of the structures. © 2017, © 2017 Informa UK Limited, trading as Taylor & Francis Group.","finite element model;

The existing SH generation schemes for BL operation use a dual inverter or a single inverter with asymmetrical winding and low slot fill factor in half of the stator. The proposed scheme comprises a single inverter with symmetrical stator winding distribution and the same fill factor for all stator slots. The generated additional SH-MMF component in the proposed scheme is induced in the harmonic winding wound on the machine rotor. A rotating bridge rectifier mounted on the rotor periphery connects the rotor harmonic winding with the rotor field winding, and rectified dc is supplied to the rotor field winding.

Buffeting response of the bridge girder at the longest single-cantilever stage was estimated via the field measurements and finite element analysis. Results of this study suggest that the drag- and lift-force coefficients, estimated from the field measurements, increase with an increase in the angle of attack. The Sears function and Davenport's approximation function were found to overestimate corresponding aerodynamic admittances in the low frequency region. In the high frequency region, the Sears function tends to underestimate the lift force and moment aerodynamic admittances. Davenport's approximation function were found to be smaller compared to those drag force aerodynamic admittance obtained via the field measurements. Lastly, the buffeting response of the bridge obtained via the finite element analysis and field measurements were found to agree well within a given range of wind speed. © 2019 Elsevier Ltd","Aerodynamic characteristics; Cable-stayed bridge; Erection stage; Field measurement","Aerodynamic drag; Angle of attack; Buffeting; Cables; Electric measuring bridges; Finite element method; Highway bridges; Lift; Plate girder bridges; Wind; Aerodynamic admittance; Aerodynamic characteristics; Approximation function; Buffeting response; Drag and lift forces; Field measurement; Long span cable stayed bridges; Low frequency regions; Cable stayed bridges; aerodynamics; bridge construction; field method; finite element method; wind velocity; Davenport; United States; Washington [United States]",,,,,"National Natural Science Foundation of China, NSFC: 51778545; State Key Laboratory for Disaster Reduction in Civil Engineering: SLDRCE-MB-03","This project was supported by the National Natural Science Foundation of China [Grant number 51778545 ] and the Open Project of the State Key Laboratory of Disaster Reduction in Civil Engineering [Grant number SLDRCE-MB-03 ].",,,,,,,,,,"Zan, S.J., Tanaka, H., Yamada, H., Wardlaw, R.L., Parameter investigation of wind-induced cable-stayed bridge motion using an aerodynamic model (1989) J Wind Eng Ind Aerodyn, 32, pp. 161-169; Scanlan, R.H., Jones, N.P., Aeroelastic analysis of cable-stayed bridges (1990) Struct Eng, 116, pp. 279-297; Ogawa, K., Shimodoi, H., Ishizaki, H., Aerodynamic stability of a cable-stayed bridge with girder, tower and cables (1992) J Wind Eng Ind Aerodyn, 42, p. 1227-38; Larsen, A., Advances in aeroelastic analyses of suspension and cable-stayed bridges (1998) J Wind Eng Ind Aerodyn, 74, pp. 73-90; Ma, C.M., Liu, Y.Z., Yeung Ngai, Li, Q.S., Experimental study of across-wind aerodynamic behavior of a bridge tower (2019) J Bridge Eng, 24, pp. 1-14; Wang, P.H., Tang, T.Y., Zheng, H.N., Analysis of cable-stayed bridges during construction by cantilever methods (2004) Comput Struct, 82, pp. 329-346; Zhang, X.J., Sun, B.N., Xiang, H.F., Analysis of cable-stayed bridges during construction by cantilever methods (2005) J Zhejiang Univ Sci, 6, pp. 175-180; Zhang, X.J., Sun, B.N., Xiang, H.F., Study of design parameters on flutter stability of cable-stayed-suspension hybrid bridges (2006) Wind Struct, 9, pp. 331-344; Zhang, Q., Zhou, X.H., Wang, J.C., Time-domain analysis of wind induced buffet and wind-resistant measures for cable-stayed bridge with steel box girder at construction stage (2013) J Chang'an Univ (Nat Sci Ed), 33, pp. 45-50; Zhu, L.D., Wang, M., Wang, D.L., Guo, Z.S., Cao, F.C., Flutter and buffeting performances of Third Nanjing Bridge over Yangtze River under yaw wind via aeroelastic model test (2007) J Wind Eng Ind Aerodyn, 95, pp. 1579-1606; Yoshizumi, F., Hiroo, I., An experimental approach on aerodynamic stability of a cable-stayed cantilever bridge (2002) J Wind Eng Ind Aerodyn, 90, pp. 2099-2111; Morgenthal, G., Yamasaki, Y., Aerodynamic behavior of very long cable-stayed bridges during construction (2011) Proc Eng, 14, pp. 1463-1471; Fujii, M., Katsuchi, H., Yamada, H., Nishio, M., (2012), pp. 313-8. , Analysis of super long-span cable-stayed suspension bridge on structural and aerodynamic characteristics.

The measured maximum deflection and strain were 0.5 mm and 110 microstrain, respectively; these data were validated through a three-dimensional (3D) finite-element model incorporating saturated soil fill, masonry arch, and their interface. The predicted strains matched well with the field measurements. The variation of the strains with the wheel positions over the arch barrel was also simulated.

This study presents a theoretical study on mapping the bridge vertical deformations to the change of track geometry. Analytical formulae are derived through the theoretical analysis to quantify the track geometry change, and validated against the finite element analysis and experimental data. Based on the theoretical formulae, parametric studies are conducted to evaluate the effects of key parameters on the track geometry of a high speed railway. The results show that the derived formulae provide reasonable prediction of the track geometry change under various bridge vertical deformations. The rail deflection increases with the magnitude of bridge pier settlement and vertical girder fault. Increasing the stiffness of the fasteners or mortar layer tends to cause a steep rail deformation curve, which is undesired for the running safety and ride comfort of high-speed railway.

When the bridge has vertical deformation, the m-th track slab is subjected to n concentrated forces (Pm1 to Pmn) from the fasteners and distributed reaction forces from the CA mortar layer (Fig. 2). The fastener forces divide the track slab into (m+1) lengths. Two local coordinate systems are introduced in Fig. 2, one for the m-th track slab and the other one for the bridge girder corresponding to the m-th track slab.

The bridge was tested under train loadings in different scenarios and at different speeds of the trains. The free vibration characteristics, strain, displacement, and acceleration of the bridge structure were measured to evaluate the dynamic responses of the train-bridge coupling system. A three-dimensional finite element model, which took into account the train-bridge coupling and track irregularities, was established to analyze the behaviors of the train-bridge system. The model was validated against the in situ test results. The impact effect on the girder was greater than that of the arch frame. The acceleration responses of the trains on the bridge increased with the train’s speed. The riding comfort of the trains was evaluated based on the measured dynamic responses of trains. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.","dynamic response; finite element model; Hybrid framed arch bridge; impact effect; in-site dynamic test; riding comfort","Arches; Beams and girders; Dynamic response; Finite element method; Railroad bridges; Railroads; Tubular steel structures; Acceleration response; Concrete-filled steel tubes; Dynamic tests; Framed arch bridges; Free vibration characteristic; impact effect; Riding comfort; Three dimensional finite element model; Arch bridges",,,,,"2014-C34; Sichuan Province Science and Technology Support Program: 2018JY0294, 2018JY0549; National Natural Science Foundation of China, NSFC: 51878563","The research was funded by the National Natural Science Foundation of China (Grant Number 51878563), the Sichuan Science and Technology Program (Grant Numbers. 2018JY0294 and 2018JY0549), and the Science and Technology Research and Development Plan of China Railway Construction (Grant No. 2014-C34).",,,,,,,,,,"American railway engineering and maintenance-of-way (2006) Manual for Railway Engineering., 1. , Washington, D.C: Association Publishing Service; Au, F.T.K., Wang, J.J., Cheung, Y.K., Impact study of cable-stayed bridge under railway traffic using various models (2001) Journal of Sound and Vibration, 240 (3), pp. 447-465; Bruno, D., Greco, F., Lonetti, P., Dynamic impact analysis of long span cable-stayed bridges under moving loads (2008) Engineering Structures, 30 (4), pp. 1160-1177; (2004) Code for rating existing railway bridge., , Beijing, China: China Ministry of Railways,.

This paper aims to assess the transverse seismic failure mechanism and ductile properties of typical inverted Y-shape RC pylons for long span cable-stayed bridges using quasi-static model tests and numerical analyses. To facilitate the limited laboratorial loading system, a simplified displacement-controlled two-node load-pattern, one at the bifurcation-node and the other at the crossbeam, is first proposed using numerical analyses. It is found the ratio of displacements at the two loading nodes is correlated generally well with the ground motion parameter, bracketed duration. A displacement ratio of 5.0 is then adopted in the test. Test results indicate a flexural damage mode with considerable ductility: plastic hinges were detected first at bottom of the upper column (i.e., above the crossbeam), then at bottom and top of the lower column, successively; multi-level displacement ductility factors are proposed to associate with numbers of plastic hinges formed in the pylon. Moreover, an experimentally validated numerical model is adopted to study the impact of loading displacement ratios on the failure mechanism and ductility. It is found that the loading displacement ratios may significantly affect them. Smaller displacement ratios tend to transfer the location of first plastic hinge from the bottom of the upper column to that of the lower column. © 2019 Elsevier Ltd","Cable-stayed bridge; Finite element method; inverted Y-shape reinforced concrete pylon; Quasi-static test; Transverse seismic failure mechanism","Cable stayed bridges; Cables; Concrete testing; Damage detection; Displacement control; Ductility; Earthquakes; Finite element method; Hinges; Numerical analysis; Numerical models; Reinforced concrete; Testing; Displacement ductility factors; Displacement ratios; Ground motion parameters; Long span cable stayed bridges; Quasi static models; Quasi-static tests; Seismic failure mechanism; Y shape; Failure (mechanical); bridge; damage; ductility; failure mechanism; finite element method; flexure; ground motion; model test; numerical model; reinforced concrete; seismic response",,,,,"National Natural Science Foundation of China, NSFC: 51778469; Ministry of Science and Technology of the People's Republic of China, MOST: 2013CB036302; China Postdoctoral Science Foundation: 2018M640448","This study is supported by the Ministry of Science and Technology of China (Grant No. 2013CB036302), National Natural Science Foundation of China (Grant No. 51778469) and China Postdoctoral Science Foundation (Grant No. 2018M640448).

The simplified transition of exact CAD models into the analysis alleviates the issues originating from geometrical discontinuities and thus, significantly reduces the design-to-analysis time in comparison to traditional FEA technique. Since its origination, the research in the field of IGA is accelerating and has been applied to various problems. However, the employment of CAD tools in the area of FEA invokes the need of adapting the existing implementation procedure for the framework of IGA. Also, the usage of IGA requires the in-depth knowledge of both the CAD and FEA fields. This can be overwhelming for a beginner in IGA. Hence, in this paper, a simplified introduction and implementation details for the incorporation of NURBS based IGA technique within the existing FEA code is presented. It is shown that with little modifications, the available standard code structure of FEA can be adapted for IGA. For the clear and concise explanation of these modifications, step-by-step implementation of a benchmark plate with a circular hole under the action of in-plane tension is included. © 2018, The Institution of Engineers (India).","Finite element analysis; Isogeometric analysis; Linear elasticity; NURBS","Bridges; Computer aided analysis; Computer aided design; Interpolation; Geometrical discontinuity; In-depth knowledge; In-plane tensions; Introduction and implementations; Isogeometric analysis; Linear elasticity; Non-uniform rational B-splines; NURBS; Finite element method",,,,,"Department of Science and Technology, Ministry of Science and Technology, India, DST: SR/FTP/ETA-0008/2014; Science and Engineering Research Board, SERB: 0008/2014","The authors are grateful to the SERB, DST for supporting this research under project SR/FTP/ETA-0008/2014.","Acknowledgement The authors are grateful to the SERB, DST for supporting this research under project SR/FTP/ETA-0008/2014.",,,,,,,,,"Zienkiewicz, O.C., Taylor, R.L., Zhu, J.Z., (2013) The Finite Element Method: Its Basis and Fundamentals, , 7, Butterworth-Heinemann, Oxford; De Lorenzis, L., Wriggers, P., Hughes, T.J.R., Isogeometric contact: a review (2014) GAMM Mitteilungen, 37 (1), pp. 85-123; Hughes, T.J.R., Cottrell, J.A., Bazilevs, Y., Isogeometric analysis: CAD, finite elements, NURBS, exact geometry and mesh refinement (2005) Comput.

First, considering the mechanical properties of PCBGCSWs, a series of equations are derived from equilibrium and compatibility conditions and constitutive relationships of the materials. In the equations, the criteria of shear flow equivalence and shear strain equivalence are adopted to determine the relationships between the concrete flanges and the corrugated steel webs (CSWs) before and after the yielding of the CSWs, respectively. Then, the solution algorithms, including a general algorithm for the entire torsional process and a simplified algorithm for the stage when both steel bars, the prestressing steel and the CSWs are in the elastic state, of the ISMMT are presented to solve all the equations. To validate the feasibility of the proposed theoretical model, the experimental results of a prismatic PCBGCSW under pure torsion available in the literature are selected for comparison. Additionally, a three-dimensional (3D) finite element (FE) model of the specimen is established using ABAQUS software. The results from the theoretical model, including the overall torque-twist curve, shear strain in the CSWs and strains in the prestressing steels and steel bars, are compared with those from the FE model and the experiment. The theoretical, numerical and experimental results are in good agreement, demonstrating that the proposed analytical model accurately predicts the torsional behaviour of the PCBGCSWs under pure torsion, including the torsional behaviour during the pre- and post-cracking stages. © 2018 Elsevier Ltd","Finite element analysis; Prestressed composite box girders with corrugated steel webs; Pure torsion; Softened membrane model; Solution algorithm; Theoretical model","ABAQUS; Bars (metal); Beams and girders; Box girder bridges; Mechanical properties; Prestressing; Shear flow; Shear strain; Torsional stress; Corrugated steel webs; Membrane modeling; Pure torsion; Solution algorithms; Theoretical modeling; Finite element method",,,,,"HMDDGC-D-03; National Natural Science Foundation of China, NSFC: 51278183; Shaanxi Provincial Science and Technology Department: 14-18K","This research is sponsored by the National Natural Science Foundation of China, China (Grant 51278183 ), the Science and Technology Program of Shaanxi Provincial Department of Transportation, China (Grant 14-18K ) and the Science and Technology Program of Transportation Bureau of Huadu District, Guangzhou, China (Grant HMDDGC-D-03 ).

As a consequence, bridge vibrations in certain frequencies are reduced, while vibrations in some other frequencies may be amplified according to the design methodology of the TMD. This paper systematically investigates the influence of these amplified frequencies on the dynamic performance of running trains subject to earthquake loads. Primarily, the design methodology of bridge-based designed TMD (BBD-TMD) is introduced. On this basis, a detailed train–track–bridge coupled dynamic model with attached BBD-TMD is established based on the multi-body dynamics theory and the finite element method. Finally, aiming at a practical engineering problem in China, the influence of BBD-TMD on running trains subject to earthquake loads is investigated. The results indicate that, for the bridge structure adopted in this study, the amplified frequency bands are similar to the natural frequencies of the car body in the train system. To design TMDs for railway bridges, the dynamic performance of running trains caused by these external installations should be seriously considered. © The Author(s) 2018.","Earthquake load; modal property TMD; train–track–bridge dynamic interaction","Dynamic response; Earthquakes; Miniature automobiles; Railroad bridges; Bridge dynamics; Dynamic performance; Earthquake load; Modal properties; Multi-body dynamic; Practical engineering problems; Tuned mass dampers; Vibration reduction measures; Vehicle performance",,,,,"KJ1600534; Chongqing Science and Technology Commission, CQ CSTC: cstc2017jcyjAX0053; Southwest Jiaotong University, SWJTU; National Key Research and Development Program of China, NKRDPC: 2013CB036206","The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This work was supported by the National Basic Research Program of China (‘‘973’’ Program) [grant number: 2013CB036206]; the open research fund of MOE Key Laboratory of High-speed Railway Engineering, Southwest Jiaotong University; the Science and Technology Project Affiliated to the Education Department of Chongqing Municipality [grant number: KJ1600534]; and the Basic Natural Science and Frontier Technology Research Program of the Chongqing Municipal Science and Technology Commission [grant number: cstc2017jcyjAX0053].",,,,,,,,,,"Brock, J.E., A note on the damped vibration absorber (1946) Journal of Applied Mechanics, 13 (4); Chen, Z., Zhai, W., Cai, C., Safety threshold of high-speed railway pier settlement based on train-track-bridge dynamic interaction (2015) Science China-Technological Sciences, 58 (2), pp. 202-210; Chen, Z., Zhai, W., Yin, Q., Analysis of structural stresses of tracks and vehicle dynamic responses in train–track–bridge system with pier settlement (2016) Proceedings of the Institution of Mechanical Engineers, , Part F, Journal of Rail and Rapid Transit; Chen, Z., Zhai, W., Tian, G., Study on the safe value of multi-pier settlement for simply supported girder bridges in high-speed railways (2018) Structure and Infrastructure Engineering, 14 (3), pp. 400-410; Den, H.J.P., (1956) Mechanical Vibrations, , (4th ed Edition), McGraw-Hill; Edalath, S., Kukreti, A.R., Cohen, K., Enhancement of a tuned mass damper for building structures using fuzzy logic (2013) Journal of Vibration and Control, 19 (12), pp. 1763-1772; Hahnkamm, E., Die Dämpfung von Fundamentschwingungen bei Veränderlicher erregerfrequenz (1933) Archive of Applied Mechanics, 4 (2), pp. 192-201; Morga, M., Marano, G.C., Optimization criteria of TMD to reduce vibrations generated by the wind in a slender structure (2013) Journal of Vibration and Control, 20 (16), pp. 2404-2416; Ormondroyd, J., Theory of the dynamic vibration absorber (1928) Transaction of the ASME, 50, pp. 9-22; Seto, K., (2010) Dynamic vibration absorber and its application, , Tokyo, Corona Publishing Co., Ltd; Sladek, J.R., Klingner, R.E., Effect of tuned-mass dampers on seismic response (1983) Journal of Structural Engineering, 109 (8), pp. 2004-2009; Soong, T.T., Dargush, G.F., (1997) Passive Energy Dissipation Systems in Structural Engineering, , John Wiley & Sons; Xu, L., Chen, Z., Zhai, W., An advanced vehicle–slab track interaction model considering rail random irregularities (2017) Journal of Vibration and Control, , 1077546317731005; Zhai, W.M., Two simple fast integration methods for large-scale dynamic problems in engineering (1996) International journal for numerical methods in engineering, 39 (24), pp. 4199-4214; Zhai, W., Xia, H., Cai, C., High-speed train–track–bridge dynamic interactions – Part I: theoretical model and numerical simulation (2013) International Journal of Rail Transportation, 1 (1-2), pp. 3-24; Zhou, D., Li, J., Hansen, C.H., Suppression of the stationary maglev vehicle–bridge coupled resonance using a tuned mass damper (2012) Journal of Vibration and Control, 19 (2), pp. 191-203; Zhu, S., Yang, J., Yan, H., Low-frequency vibration control of floating slab tracks using dynamic vibration absorbers (2015) Vehicle System Dynamics, 53 (9), pp. 1296-1314","Chen, Z.; School of Mechanotronics and Vehicle Engineering, China; email: chenzhaowei@my.swjtu.edu.cn",,,"SAGE Publications Inc.",,,,,10775463,,JVCOF,,"English","JVC/J Vib Control",Article,"Final","All Open Access, Bronze",Scopus,2-s2.0-85047386656

In AASHTO LRFD design specification, four kinds of the limit states have been deliberated including strength, service, fatigue, and extreme events. Extreme event limit states have been divided into load combination including earthquake, and vehicle collision. The provision of the vehicular collisions based on the equivalent statistic shear force associated with no load factor in a related load combination. Since the essence of the AASHTO LRFD bridge design specification has been established based on the reliability analysis, therefore, there is a need for reliability analysis of this type of the extreme events. The primary intention of this paper is to present a novel study to determine a performance-based design of the bridge piers subjected to the vehicular collision. As state-of-the-art in this study, severity levels of vehicular configurations are classified based on the available momentum data. Accordingly, the performance levels of the pier are categorized corresponding to the damage state of the pier subjected to the vehicular collision. To do so, numerous piers were modeled using the finite element method (FEM). In addition to the new definition of the severity and performance levels, the results showed that there is a correlation between both extreme events limits. This fact indicates that the piers which have been already designed based on the severe earthquake events can stand for a better performance level due to the vehicular collision events. © 2019 Elsevier Ltd","Extreme event; Highway bridge pier; Impact loading scenario; Performance level; Vehicle collision","Bridge piers; Earthquakes; Failure (mechanical); Highway bridges; Specifications; Structural design; Design specification; Extreme events; Impact loadings; Performance based design; Performance level; Severe earthquakes; Vehicle collisions; Vehicular collisions; Reliability analysis",,,,,,,,,,,,,,,,"Wardhana, K., Hadipriono, F.C., Analysis of recent bridge failures in the United States (2003) J.

For such cases, it is required that inspection of these bridges be carried out using costly ""arms-length"" approach. New techniques in structural health monitoring (SHM) that use non-contact sensors and self-powered wireless sensors present alternative approach for inspection. Application of such techniques would allow timely detection and application of repair and strengthening, in other word, providing for more resilient bridges. This paper investigates the feasibility of using a handful of self-powered wireless or non-contact sensors for continuous or periodic monitoring and detection of fracture in steel plate girder bridges. To validate this concept, vibration measurements were performed on an actual bridge in the field, and detailed finite element analyses were carried out on a multi-girder bridge. The records obtained show that vibration amplitude was significantly increased for fractured girder, and a distinct pattern of strain variation was registered in the vicinity of fracture, all of which can be detected effectively with relevant sensors. Moreover, the amplitude and frequency of the vibration was shown to be significant enough for providing the required power for typical sensor(s). © 2019 by the authors.","Damage detection; Fracture critical; Health monitoring; Laser vibrometer; Non-contact sensor; Self-powered sensor; Steel bridges; Wireless sensors",,,,,,,"Acknowledgments: The authors greatly acknowledge the internal support by the Department of Civil and Environmental Engineering at Florida International University.

A multi-Fickian hygro-thermal model, previously implemented by some of the authors, is extended by including the dependency of wood sorption on temperature above and below zero degrees Celsius to predict moisture, temperature and relative humidity in wood under Northern European climates. The performance of the model in the presence of protective paints is particularly investigated. The finite element analysis based on the proposed model simulates the hygro-thermal behaviour of a glue-laminated beam of Älsvbacka Bridge located in Skellefteå (North of Sweden). The beam, coated by paints and claddings, was monitored by using wireless sensors in a previous research. Comparisons with the available measurements reveal that the numerical model is able to predict the moisture content in locations sheltered from rain and sun with moisture levels below the fibre saturation point. A study of the influence of different protective paints shows that the maximum and minimum moisture content at various depths along horizontal paths of the beam cross section, as well as the moisture gradients in different seasonal periods, are strongly affected by the type of paint. The proposed numerical approach is a promising tool to facilitate sensor-based monitoring techniques and to optimize the choice of protective paints for improved performance of timber bridges and other wooden structures under variable climates. © 2019 Elsevier Ltd","Coatings; European climates; FEM; Moisture content; Multi-Fickian models; Timber bridges","Coatings; Finite element method; Moisture; Moisture determination; Numerical models; Thermoanalysis; Timber; Wooden bridges; Wooden buildings; European climates; Fibre saturation point; Fickian model; Glue-laminated beams; Monitoring techniques; Numerical approaches; Temperature and relative humidity; Timber bridge; Climate models",,,,,,,,,,,,,,,,"Song, J., Chen, C., Zhu, S., Zhu, M., Dai, J., Ray, U., Processing bulk natural wood into a high-performance structural material (2018) Nature, 554, pp. 224-228; Malo, K.A., Abrahamsen, R.B., Bjertnæs, M.A., Some structural design issues of the 14-storey timber framed building “Treet” in Norway (2016) Eur.

Under different loading rates and directions, we experimentally and numerically investigated the strain rate effect on the impact compressive behavior of 3-D angle-interlock woven composites (3-D AWCs) composed of carbon fiber and epoxy resin. Based on the factual geometrical architecture of 3-D AWC, the meso-scale model, which considers the interfacial damage between the reinforcements and matrix, was established to visually characterize the deformation history and damage morphologies of 3-D AWCs during impact compression process. Further, we performed high strain rate compressive tests on the split Hopkinson pressure bar (SHPB) apparatus integrated with a high-speed photography system for capturing images of progressive damage process to validate the proposed mesoscopic model. The stress-strain curves of various strain rates show strain rate effect varies depending on loading direction. The rate sensitivity on the compressive failure strength exists at weft direction and through-thickness direction except for warp direction. Moreover, both from images and finite element model results, the localized adiabatic shear band induced by intense plastic strain, initiates mainly from epoxy resin matrix and propagates along the interface at all three loading directions. © 2018 Elsevier Ltd","3-D angle-interlock woven composite; Adiabatic shear band localization; Finite element analysis (FEA); High-speed photography; Strain rate effect","Bridge decks; Carbon fibers; Epoxy resins; Failure (mechanical); Finite element method; High speed photography; Mechanical testing; Polymer matrix composites; Polypropylenes; Reinforcement; Shear bands; Shear flow; Stress-strain curves; Structural optimization; Weaving; 3-D angle-interlock woven composites; Adiabatic shear band; Compressive behavior; Dynamic mechanical behavior; Fiber-reinforced-polymeric; Optimization of structures; Split Hopkinson pressure bars; Strain rate effect; Strain rate",,,,,"National Natural Science Foundation of China, NSFC: 11572085, 51675095; Changjiang Scholar Program of Chinese Ministry of Education; Fundamental Research Funds for the Central Universities","The authors acknowledge the financial supports from the Chang Jiang Scholars Program and National Science Foundation of China (Grant Nos. 11572085 and 51675095 ).

The bridge is discretized into a group of mass particles linked by massless beam elements and the multi-body coach with suspension systems is simulated as a set of mass particles connected by parallel spring-dashpot units. Then the equation of motion of each mass particle is solved individually and the internal forces induced by pure deformations in the massless beam elements are calculated by a fictitious reverse motion method, in which the structural stiffness matrices need not be updated or factorized. Though the vector-form equations resulting from the VFIFE method cannot be used to compute the structural frequencies by the eigenvalue approach, this study proposes a numerical free vibration test to identify the bridge frequencies for evaluating the bridge damping. Numerical verifications demonstrate that the present VFIFE method performs as accurately as previous numerical ones. The results show that the couplers play an energy-dissipating role in reducing the car bodies' response due to the bridge-induced resonance, but not in their response due to the train-induced resonance because of the bridge's intense vibration. Meanwhile, a dual-resonance phenomenon in the train-bridge system occurs when the coach-coupler effect is considered in the vehicle model. © 2019 World Scientific Publishing Company.","Coupler; mass particle; resonance; train-bridge system; vector form intrinsic finite element","Automobile bodies; Automobile suspensions; Eigenvalues and eigenfunctions; Equations of motion; Miniature automobiles; Numerical methods; Railroad bridges; Resonance; Stiffness matrix; Suspensions (components); Suspensions (fluids); Vectors; Coupler; Free-vibration tests; Numerical verification; Structural frequencies; Structural stiffness; Train-bridge interaction; Train-bridge systems; Vector form intrinsic finite elements (VFIFE); Finite element method",,,,,"2017YFC0806100; LR13E080001; National Natural Science Foundation of China, NSFC: 51478429, 51522811, 90915008, U1709216; Ministry of Science and Technology of the People's Republic of China, MOST: 102-2923-E-032-002-MY3, 106-2221-E-032-022; Fundamental Research Funds for the Central Universities: 2015XZZX004-28","This work is supported by National Key R & D Program of China (2017YFC0806100), National Natural Science Foundation of China (U1709216, 51522811, 51478429 and 90915008), Zhejiang Provincial Natural Science Foundation of China (LR13E080001), the Fundamental Research Funds for the Central Universities (2015XZZX004-28) and by the Ministry of Science & Technology of Taiwan via the Grant Nos.

The concept was developed to provide a procedure that supports enhanced assessments with better understanding of the structure and more precise predictions of the load-carrying capacity. In order to demonstrate and examine the multi-level strategy, a continuous multi-span prestressed concrete girder bridge, tested until shear failure, was investigated. Calculations of the load-carrying capacity at the initial level of the multi-level strategy consistently resulted in underestimated capacities, with the predicted load ranging from 25% to 78% of the tested failure load, depending on the local resistance model applied. The initial assessment was also associated with issues of localising the shear failure accurately and, consequently, refined structural analysis at an enhanced level was recommended. Enhanced assessment using nonlinear finite element (FE) analysis precisely reproduced the behaviour observed in the experimental test, capturing the actual failure mechanism and the load-carrying capacity with less than 4% deviation to the test. Thus, the enhanced level of assessment, using the proposed multi-level strategy, can be considered to be accurate, but the study also shows the importance of using guidelines for nonlinear FE analysis and bridge-specific information. © 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group.","Bridges; codes; full-scale failure test; modelling strategy; multi-level assessment; nonlinear finite element analysis; prestressed concrete; shear capacity; structural behaviour","Bridges; Concrete beams and girders; Concrete bridges; Concrete testing; Finite element method; Load limits; Loads (forces); Nonlinear analysis; Prestressed concrete; Structural analysis; codes; Failure test; Modelling strategies; Multi-level assessment; Non-linear finite-element analysis; Shear capacity; Structural behaviour; Failure (mechanical)",,,,,"Luleå Tekniska Universitet, LTU; Stiftelsen Åforsk; Bundesamt für Berufsbildung und Technologie, BBT; Trafikverket","This study has been funded by Swedish Transport Administration (Trafikverket), Program for Research and Innovation for Civil Structures in the Transport Sector (BBT), Luossavaara-Kiirunavaara AB (LKAB), Hjalmar Lundbohm Research Center (HLRC), Development Fund of the Swedish Construction Industry (SBUF), ÅForsk Foundation, Norut Northern Research Institute and Luleå University of Technology (LTU).","This study has been funded by Swedish Transport Administration (Trafikverket), Program for Research and Innovation for Civil Structures in the Transport Sector (BBT), Luossavaara-Kiirunavaara AB (LKAB), Hjalmar Lundbohm Research Center (HLRC), Development Fund of the Swedish Construction Industry (SBUF), ÅForsk Foundation, Norut Northern Research Institute and Luleå University of Technology (LTU).

Characterization and condition evaluation of bridges substructure and foundations will not only help to decrease the vulnerability to natural hazards but also provide opportunities for their reuse with considerable benefits. In this paper, the feasibility of leveraging structural identification techniques to characterize bridge substructures and foundations is investigated. A three-span simply supported bridge located in Mossy, West Virginia, USA, is used as a study case. Modal analysis and finite element model updating techniques are used to investigate and estimate the uncertainties and conditions of the substructure. Updated finite element model for this structure provides valuable information for bridge condition assessment and proves how structural identification is a viable tool for the case considered. © 2018 John Wiley & Sons, Ltd.","bridge substructure; condition assessment; foundation; modal analysis; model updating; structural identification","Bridges; Foundations; Modal analysis; Structural analysis; Uncertainty analysis; Bridge substructures; Condition assessments; Experimental modal analysis; Finite-element model updating; Model updating; Simply supported bridge; Structural condition; Structural identification; Finite element method",,,,,,,,,,,,,,,,"(2015) Bridge-tables of frequenctly requested NBI information, , http://www.fhwa.dot.gov/bridge/britab.cfm, Washington, DC, accessed on 2016.

These bridges must be designed to be resilient to both episodic (vessel collision) and chronic (structural deterioration) hazards. To achieve this goal, this paper will develop a novel fragility assessment framework for reinforced concrete (RC) bridges under vessel collision with the corrosion-induced structural deterioration being considered. The cornerstone of this fragility assessment framework is the computational model with the capability of accurately predicting vessel impact response and corrosion-induced deterioration measures. In doing so, detailed finite element (FE) modeling approaches, including reinforcement bond-slip effects, are firstly developed and validated by the experimental results. The effects of corrosion are characterized by a series of deterioration measures that can be implemented into FE models. These FE modeling approaches were utilized to model the baseline bridge. Three different exposure periods (i.e., 0, 50, and 100 years) and two types of vessel (barge and ship) are considered. Driven by the response data generated by the FE model, a surrogate model is developed to feature both accurate vessel-impact response estimates and negligible computation cost. This surrogate model is then employed to create fragility curves using Monte Carlo methods. Fragility analysis results have indicated the significant role played by corrosion in increasing the vulnerability of RC bridges under vessel collision throughout the lifetime of the baseline bridge. The probability of bridge collapse rises by almost 100% near the end of the bridge's life. Significant differences were found for the damage evolution of the deteriorated bridge under barge impacts and ship impacts. Particular critical impact speeds were observed in the barge-impact response, but not during ship collisions. © 2020 Elsevier Ltd","Corrosion deterioration; Fragility analysis; simplified FE modeling; Surrogate model; Vessel impact","Barges; Corrosive effects; Deterioration; Hazards; Monte Carlo methods; Reinforced concrete; Ships; Aggressive environment; Bond-slip effects; Computation costs; Computational model; Corrosion-induced deterioration; Fragility analysis; Fragility assessment; Structural deterioration; Bridges; bridge; collision; corrosion; finite element method; modeling; reinforced concrete; risk assessment; surrogate method; vessel",,,,,"National Natural Science Foundation of China, NSFC: 51978258; Natural Science Foundation of Hunan Province: 2020JJ4186; Science and Technology Department of Guangxi Zhuang Autonomous: AD19245058; 5511 Science and Technology Innovation Talent Project of Jiangxi Province: 2020RC3018; Henan Province Science and Technology Innovation Talent Program","This research is supported by the National Natural Science Foundation of China (Grant Number: 51978258), the Youth Science and Technology Innovation Talent Project of Hunan Province (Grant Number: 2020RC3018) and the National Natural Science Foundation of Hunan Province (Grant Number: 2020JJ4186), and the Science and Technology Base and Talent Special Project of Guangxi Zhuang Autonomous (Grant Number: AD19245058).","This research is supported by the National Natural Science Foundation of China (Grant Number: 51978258), the Youth Science and Technology Innovation Talent Project of Hunan Province (Grant Number: 2020RC3018) and the National Natural Science Foundation of Hunan Province (Grant Number: 2020JJ4186), and the Science and Technology Base and Talent Special Project of Guangxi Zhuang Autonomous (Grant Number: AD19245058).",,,,,,,,,"Vu, N.S., Yu, B., Li, B., Prediction of strength and drift capacity of corroded reinforced concrete columns (2016) Constr Build Mater, 115, pp. 304-318; Ma, Y., Che, Y., Gong, J., Behavior of corrosion damaged circular reinforced concrete columns under cyclic loading (2012) Constr Build Mater, 29, pp. 548-556; Guo, A.X., Yuan, W.T., Li, H.T., Li, H., Structural strength deterioration of coastal bridge piers considering non-uniform corrosion in marine environments (2018) Earthq Eng Eng Vibrat, 17, pp. 429-444; Panchireddi, B., Ghosh, J., Cumulative vulnerability assessment of highway bridges considering corrosion deterioration and repeated earthquake events (2018) Bull Earthq Eng, 1-36; Choe, D.-E., Gardoni, P., Rosowsky, D., Haukaas, T., Probabilistic capacity models and seismic fragility estimates for RC columns subject to corrosion (2008) Reliab Eng Syst Saf, 93, pp. 383-393; Alipour, A., Shafei, B., Shinozuka, M., Performance evaluation of deteriorating highway bridges located in high seismic areas (2011) J Bridge Eng, 16, pp. 597-611; Castel, A., François, R., Arliguie, G., Mechanical behaviour of corroded reinforced concrete beams—Part 1: Experimental study of corroded beams (2000) Mater Struct, 33, pp. 539-544; Zhu, W., François, R., Corrosion of the reinforcement and its influence on the residual structural performance of a 26-year-old corroded RC beam (2014) Constr Build Mater, 51, pp. 461-472; Lim, S., Akiyama, M., Frangopol, D.M., Jiang, H., Experimental investigation of the spatial variability of the steel weight loss and corrosion cracking of reinforced concrete members: novel X-ray and digital image processing techniques (2016) Struct Infrastruct Eng, 13, pp. 118-134; Cairns, J., Du, Y., Law, D., Structural performance of corrosion-damaged concrete beams (2008) Mag Concr Res, 60, pp. 359-370; AASHTO.

Prof. Luciano Gualberto 380, São Paulo, 05508-010, Brazil","This article presents an efficient computational methodology for solving the train-track-bridge interaction problem, including track irregularities and considering the non-linear behaviour of the track-deck interface. One of the novelties of the work is the proposal of a specific finite element used to model the track-deck interface, based on an assembly of a friction contact element and a non-linear spring, which is generally not used in non-linear dynamic problems. This element automatically performs changes in the longitudinal resistance of the track, according to the positions of the traffic loads, and takes into account the loading history. The dynamic analyses are performed based on an iterative methodology implemented in AIVE software, which takes advantage of the advanced modeling tools of Abaqus software controlled on Matlab. This software ensures flexibility in the selection of the methods for solving the dynamic problem and allows the incorporation of non-linearities in the vehicle and bridge models, including their interfaces. A parametric study was performed in order to demonstrate the importance of including the non-linear behaviour at the track-deck interface in the evaluation of the dynamic responses of the bridge and vehicle subsystems, under different scenarios of deck temperature, horizontal stiffness of the supports and deck cross-sections. The results show that the responses of the track-deck interface are more influenced by the effects of temperature variations than by the effects of vertical traffic loads, particularly for medium and large span bridges. Significant plastic incursions were detected at the track-deck interface under realistic temperature scenarios, particularly on the side of the mobile support. Under vertical traffic loads, the extension of the regions with plastic behaviour proved to be sensitive to variations in the horizontal stiffness of the support. Additionally, another important achievement of this study was the evaluation of the plastic incursions at the track-deck interface for different bridges typologies. Relevant incursions were detected for medium and large span bridges, where the extension of these regions can reach 25–55% of the bridge span, otherwise, for short span bridges, practically no significant plasticized regions were identified. Non-linear incursions on the track-deck interface cause an overall reduction of the track-bridge stiffness, leading to an increase of the vertical movements of the bridge, and, inherently, of the vehicle's dynamic responses. The evaluation of the extension of the ballast plastic regions for the different analysis scenarios, which is still a topic shortly addressed in the bibliography, will be particularly useful for upgrading the existing methods for assessment of the dynamic behavior of railway bridges. © 2020 Elsevier Ltd","Dynamic analyses; Iterative method; Non-linear behaviour; Parametric study; Track-deck interface; Train-track-bridge system","ABAQUS; Ballast (railroad track); Dynamic response; Iterative methods; MATLAB; Stiffness; Temperature; Vehicles; Advanced modeling tools; Computational methodology; Effects of temperature; Horizontal stiffness; Iterative methodology; Nonlinear behaviours; Specific finite element; Train-bridge systems; Railroad bridges; bridge; computer simulation; dynamic response; finite element method; loading; numerical model; software; structural response; vertical movement",,,,,"Fundação para a Ciência e a Tecnologia, FCT; Conselho Nacional de Desenvolvimento Científico e Tecnológico, CNPq: 167555/2017-0; Ministério da Ciência, Tecnologia e Ensino Superior, MCTES; Institute of Research and Development in Structures and Construction","The first author PhD researcher expresses his gratitude to the CNPq for the financial support through the Postdoctoral Process 167555/2017-0 .

Currently, UHPC is commonly used in precast bridge deck joints and connections. As the UHPC market grows, the material will have a great potential to extend to larger structural applications. However, there is no guidance yet on best practices or optimum structural designs that fully utilize the UHPC superior mechanical properties for larger components. The objective of this study is to better understand the overall behavior, failure mechanism, and effect of reinforcement and design details of UHPC bridge columns using detailed finite element modeling. The pushover response of a two-column bridge pier with the typical geometry and gravity loads obtained from a representative California bridge is investigated when UHPC is used instead of conventional concrete for the columns. A detailed sensitivity/parametric analysis is conducted to assess the effect of different steel fiber ratio, longitudinal reinforcement ratio, and steel grades of reinforcement bars on the overall structural behavior of the columns. The total strain crack model, as readily implemented in DIANA FEA, is utilized with user-defined input to model the UHPC constitutive material behavior. The UHPC stress-strain relationships in tension and compression are independently defined using uniaxial curves from the literature. For comparison, the two-column bent of conventional concrete is modeled and used as the reference case to evaluate the relative increase in load capacity of the UHPC bridge columns. © 2020 Elsevier Ltd",,"Bridge piers; Concrete industry; Construction industry; Reinforcement; Seismic design; Sensitivity analysis; Steel fibers; Stress-strain curves; Structural optimization; Ultra-high performance concrete; Constitutive materials; Conventional concrete; Longitudinal reinforcement; Optimum structural design; Stress-strain relationships; Structural applications; Tension and compression; Ultra high performance concretes (UHPC); Failure (mechanical); bridge; column; dynamic response; finite element method; numerical model; pier; seismic response; sensitivity analysis; structural response",,,,,,,,,,,,,,,,"Valikhani, A., Jahromi, A.J., Azizinamini, A., (2017), Retrofitting damaged bridge elements using thin ultra high performance shell elements.

These materials have self-healing properties, or the ability to recover from scratches and cuts. Applied forces can have a significant impact on the mechanical properties of non-dynamic systems. However, the impacts of forces on the self-healing ability of dynamically bonded systems are still poorly understood. Here, we used a combined computational and experimental approach to study the impact of mechanical forces on the self-healing of a model dynamic covalent crosslinked polymer system. Surprisingly, the mechanical history of the materials has a distinct impact on the observed recovery of the mechanical properties after the material is damaged. Higher compressive forces and sustained forces lead to greater self-healing, indicating that mechanical forces can promote dynamic chemistry. The atomistic details provided in molecular dynamics simulations are used to understand the mechanism with both non-covalent and dynamic covalent linkage responses to the external loading. Finite element analysis is performed to bridge the gap between experiments and simulations and to further explore the underlying mechanisms. The self-healing behavior of the crosslinked polymers is explained using reaction rate theory, with the applied force proposed to lower the energy barrier to bond exchange. Overall, our study provides fundamental understanding of how and why the self-healing of cross-linked polymers is affected by a compressive force and the force application time. © 2020 The Royal Society of Chemistry.",,"Computation theory; Crosslinking; Mechanical properties; Mechanisms; Molecular dynamics; Polymers; Reaction kinetics; Self-healing materials; Cross-linked polymers; Dynamic chemistries; Experimental approaches; Molecular dynamics simulations; Reaction rate theory; Self-healing abilities; Self-healing properties; Tribological applications; Dynamics; Dynamics; Force; History; Impact; Materials; Mechanical Properties; Polymers; Reaction Kinetics",,,,,"National Science Foundation, NSF: 1749730, DMR-1749730","B.

FE2 analyses typically comprise two levels of Finite Element (FE) simulations that are performed concurrently. At the macroscale level, the entire heterogeneous material or structure is discretized into homogenized continuum finite elements. Homogenized constitutive relations are not required for the macroscale calculations. Instead they are obtained from microscale level FE simulations on representative volume elements (RVE) of the material where the different phases of the heterogeneous material are explicitly modelled. The paper presents how the two levels of simulations can be collapsed into one by combining the equations governing both levels of FE analyses. The result is a single system of equations in terms of only the microscale level degrees of freedom, d̃. The equations take the familiar form of Kd̃=f̃. It is shown that K comprises the stiffness contributions from the RVE meshes scaled by an amount that is dependent on the relative sizes of the macroscale finite element and the RVE mesh, and the geometry of and choice of shape functions for the macroscale finite element. The derived force vector, f̃, is a direct outcome of the usual kinematic relations used to bridge the nodal displacements across the macroscale and microscale. We also show how this Direct FE2 can be carried out as a single simulation on any commercial FE software that supports multipoint constraints (MPC). The Direct FE2models are shown to give similar results to full FE meshes of heterogeneities throughout the entire domain with significantly less degrees of freedom. We further demonstrate that in-built capabilities of the commercial codes are naturally available with Direct FE2 through examples involving large deformation, plasticity and viscoelasticity. © 2019 Elsevier B.V.","Composites; FE2 method; Heterogeneous structures; Multi-level FEM; Multi-point constraints (MPCs); Multi-scale finite element computation","Composite materials; Computer software; Degrees of freedom (mechanics); Constitutive relations; Finite element computations; Finite element simulations; Heterogeneous materials; Heterogeneous structures; Multi point constraints; Multilevels; Representative volume element (RVE); Finite element method",,,,,"National University of Singapore, NUS; Ministry of Education - Singapore, MOE: R-265-000-650-114","The support from the Ministry of Education, Singapore ( R-265-000-650-114 ) is gratefully acknowledged.

The elastic beam theory and the Castigliano's second theorem were utilized to establish the mathematical model with consideration of the deformation of input beams, output beam, connecting beams and flexure hinges. The proposed model was compared with existing theoretical models and finite element model (FEM), and the results validated that the proposed model featured a better performances and was the most proximal model to the FEM analysis. With the interval of the adjacent flexible hinges changed, the error at the peak of amplification ratio with the FEM was limited to 6.76%, which was lower than most of the typical existing models. To further verify the effectiveness and expansibility of the proposed method, a decoupled XY precision positioning stage was investigated. Considering the influence of the loading force exerted on amplification mechanism, the displacement amplification ratio model of the positioning stage was established, and the results were further proved through the finite element simulation. The experimental results presented that the amplification ratios for X-direction and Y-direction motions are 5.83 and 5.71, the measured workspace of the stage is 174.9 μm × 171.3 μm, and the cross-coupling error was evaluated to less than 3%. © 2019","Bridge-type amplification mechanism; Castigliano's second theorem; Displacement amplification ratio; Elastic beam theory; The exact loading force","Finite element method; Hinges; Amplification mechanism; Castigliano; Displacement amplification; Elastic beam; Loading force; Loading",,,,,"Natural Science Foundation of Shanghai: 17DZ1205000, 19ZR1474000; National Natural Science Foundation of China, NSFC: 51605271, 61973207, 91648119","This work was supported by the National Natural Science Foundation of China , China, No. 61973207 , 91648119 , and 51605271 ; and the Natural Science Foundation of Shanghai , China, No. 19ZR1474000 and 17DZ1205000 .",,,,,,,,,,"Huo, F., Zheng, Z., Zheng, G., Giam, L.R., Zhang, H., Mirkin, C.A., Polymer pen lithography (2008) Science; Qu, J., Chen, W., Zhang, J., Chen, W., A large-range compliant micropositioning stage with remote-center-of-motion characteristic for parallel alignment (2015) Microsyst.

Due to the lack of commonly accepted design procedures, the whole designing process was based on FEA and strongly supported by testing. Also, the result – a demonstrative vehicular bridge – was the subject of investigation focused on evaluating the bridge performance under proof load. A prototype hybrid structure with the span length of 21.0 m was subjected to a series of static and dynamic loading tests. The results obtained from the investigation were used to verify the applied design procedure by determining the key behaviour characteristics: stiffness, strength, load transverse distribution, degree of composite action, and dynamic performance and comparing them with design predictions. Linear FEA was found to predict accurately the flexural behaviour of hybrid bridge systems in the elastic range. With respect to the static and dynamic performance, the novel hybrid bridge system fully conformed to design requirements of relevant standards. However, the field test results indicated that the design assumptions seem to be conservative because a significant margin of safety was revealed, particularly in terms of FRP strength. Therefore, some implications of field evaluation results for future designs of hybrid FRP-concrete bridges have been presented in the paper. © 2019 Elsevier Ltd","Composite action; Design procedure; Dynamic performance; FEA; FRP-concrete bridge; Hybrid structure; Load distribution; Proof test; Stiffness; Strength","Concrete bridges; Design; Dynamic loads; Finite element method; Light weight concrete; Mechanisms; Reinforced concrete; Stiffness; Composite action; Design procedure; Dynamic performance; Hybrid structure; Load distributions; Proof test; Strength; Bridges",,,,,"Narodowe Centrum Badań i Rozwoju, NCBR","This work was created within the framework of the project: “Combridge – An innovative FRP composite road bridge”.

To further enhance the resilience, prestressed precast segmentally-erected (PPC) piers were fabricated and tested, reinforced with a hybrid of unbonded tendons and high-strength (H) energy dissipation (ED) bars. In this study: (1) cyclic loading tests for the PPC piers with “H” ED bars were reported, and the seismic resilience was quantitatively evaluated and compared with the PPC piers with normal-strength (L) ED bars; (2) the computationally efficient fiber-based finite element (FE) model is developed for the tested PPC piers. Experimental results demonstrated that the “H” ED bars brought out apparent amelioration, in terms of load-carrying, ductility and self-centering capacities. In consideration of rising seismic resilience, “H” ED bars are recommended to replace currently large-scale adopted “L” ED bars in the PPC pier of vital bridges. Through validation with experimental results, the proposed fiber-based FE model is able to provide satisfactory predictions for seismic responses of the tested PPC piers. © 2019","Cyclic loading; Fiber-based finite element; High-strength bar; Prestressed precast segmental piers; Resilience","Bridge piers; Cyclic loads; Energy dissipation; Prestressed concrete; Quality control; Reinforcement; Seismology; Textile fibers; Computationally efficient; High-strength bars; Pre-cast; Precast segmental bridge; Residual displacement; Resilience; Satisfactory predictions; Urban traffic system; Wire; bridge; cyclic loading; experimental study; finite element method; numerical model; reinforcement; resilience; seismic response; strength; support structure",,,,,"BK20180389; National Natural Science Foundation of China, NSFC: 51808113; National Key Research and Development Program of China, NKRDPC: 2017YFC0806009","This research is funded by the National Key R&D Program of China (No. 2017YFC0806009 ), the National Natural Science Foundation for Young Scientists of China ( 51808113 ), the National Natural Science Foundation for Young Scientists of Jiangsu Province ( BK20180389 ).

Proper identification of the surface roughness of a bridge will help minimize the associated uncertainties and improve the accuracy of numerical simulation. This paper presents a method for estimating the surface roughness profile from the responses extracted from a vehicle instrumented with accelerometers passing on the bridge tested. By letting the vehicle run along the bridge multiple times with different added masses, an estimation of the roughness profile can be obtained based on the vehicle-bridge interaction theory. No baseline data is required. Three simplified vehicle models have been used in this study, i.e. spring-mass model, spring-damper-mass model and half-vehicle model. The feasibility and effectiveness of this method are evaluated by finite element simulation with a simply supported bridge and a continuous bridge. The performance of this method for different levels of road surface roughness is assessed by suitable error indicators. A parametric study about the influence of vehicle and bridge parameters, measurement noise and structural damage on the identified results have been carried out. © 2019 World Scientific Publishing Company.","Bridge; finite element method; surface roughness profile; vehicle-bridge interaction","Bridges; Digital storage; Finite element method; Structural analysis; Vehicles; Finite element simulations; Half vehicle model; Road surface roughness; Simply supported bridge; Spring mass models; Structural damages; Surface roughness profiles; Vehicle-bridge interaction; Surface roughness",,,,,,,,,,,,,,,,"Yang, Y.B., Lin, C.W., Yau, J.D., Extracting bridge frequencies from the dynamic response of a passing vehicle (2004) J.

Recently, steel plates with engineered cut-outs are introduced to have controlled yielding. These structural elements behave as shear links are able to post pone brittle limit states, leading to resistance against early fracture. Among which, a promising type of link is butterfly-shaped link, for which the demand moment diagram aligns with capacity moment diagram to efficiently implement the steel. Previous studies show that these elements are used as appropriate choice for structural seismic fuse system since they are able to experience large drifts with sufficient ductility and full hysteric behavior. Therefore, the appropriate geometrical properties for these links are in need of further investigations. In this study, the finite element methodology is initially validated with experimental test. Then optimization criteria is introduced for set of 300 models to investigate the desired geometrical properties for having most energy dissipation with less fracture potential. This paper represents optimization process with which the geometrical properties of butterfly shaped link is improved to have sufficient energy dissipation performance and less potential for fracture. The pushover curves and equivalent plastic strains are obtained from ABAQUS through an iterative process. The Grey Wolf Optimizer method is adopted for optimization methodology due to having strong capability in non-linear system. It can be found that by implementation of optimization methodology the links are designed to have a mode switch from flexural yielding limit state to shear yielding and are able to dissipate energy over a less equivalent plastic strain value. © Patron Editore S.r.l.Il carico di taglio applicato alle strutture è contrastato dall'implementazione di dissipatori isterici come sistema di resistenza sismica strutturale. Recentemente, sono state introdotte piastre in acciaio con intagli progettati per avere una risposta controllata. Questi elementi strutturali che si comportano come i link a taglio sono in grado ritardare forme di collasso fragili. Tra questi, un tipo di collegamento molto promettente è il cosiddetto collegamento a forma di farfalla, per il quale il diagramma del moment richiesto si allinea al diagramma del momento ottenuto. Studi precedenti mostrano che questi elementi sono usati come scelta appropriata per il sistema di fusibili sismici poiché sono in grado di sperimentare grandi escursioni in campo plastico con duttilità sufficiente e comportamento isterico completo. Pertanto, le proprietà geometriche appropriate per questi collegamenti necessitano di ulteriori indagini. In questo studio, la metodologia degli elementi finiti è inizialmente validata con test sperimentali. Quindi vengono introdotti criteri di ottimizzazione per un set di 300 modelli per studiare le proprietà geometriche desiderate per avere la maggior parte della dissipazione di energia con un minor potenziale di frattura. Questo lavoro propone il processo di ottimizzazione con il quale le proprietà geometriche del dispositivo a forma di farfalla sono state migliorate per avere prestazioni di dissipazione dell'energia sufficienti e minor potenziale di frattura. Le curve di pushover e le deformazioni plastiche equivalenti sono ottenute da ABAQUS attraverso un processo iterativo. Il metodo di ottimizzazione ""Grey Wolf"" è stato adottato grazie all'elevata capacità nell'ambito di sistemi non lineari. Si può scoprire che mediante l'implementazione del metodo di ottimizzazione i link sono progettati per avere un cambio di modalità di rottura dalla flessione al taglio e sono in grado di dissipare energia su un valore di deformazione plastica minore. © Patron Editore S.r.l.","""Grey Wolf""; Butterfly-shaped links; Deformazioni plastiche; Elementi finiti; Finite element; Fusibili sismici strutturali; Grey wolf optimization; Link a forma di farfalla; Plastic strain; Structural Seismic fuses","Bridge decks; Energy dissipation; Finite element method; Fracture; Geometry; Iterative methods; Linear systems; Plastic deformation; Seismology; Strain; Butterfly-shaped links; Deformazioni plastiche; Elementi finiti; Fusibili sismici strutturali; Grey Wolf; Link a forma di farfalla; Shape optimization",,,,,,,,,,,,,,,,"Castaldo, P., Palazzo, B., Perri, F., Fem simulations of a new hysteretic damper: The dissipative column (2016) Ingegneria Sismica, 33 (1), pp. 34-45; Deng, K., Pan, P., Sun, J., Liu, J., Xue, Y., Shape optimization design of steel shear panel dampers (2014) Journal of Constructional Steel Research, 99, pp. 187-193; Farzampour, A., (2019) Evaluating Shear links for Use in Seismic Structural Fuses, , Doctoral dissertation, Virginia Tech, United States; Farzampour, A., Eatherton, M.R., Lateral torsional buckling of butterfly-shaped shear links (2017) Proc. of the SSRC Annual Stability Conference Structural Stability Research Council, , San Antonio, USA; Farzampour, A., Eatherton, M.R., Investigating limit states for butterfly-shaped and straight shear links (2018) Proc. of the 16th European Conference on Earthquake Engineering, , 16ECEE, Thessaloniki, Greece; Farzampour, A., Eatherton, M.R., Parametric study on butterfly-shaped shear links with various geometries (2018) Proc. of the 11th National Conference on Earthquake Engineering, , 11NCEE, Los Angeles, USA; Farzampour, A., Eatherton, M.R., Yielding and lateral torsional buckling limit states for butterfly-shaped shear links (2019) Engineering Structures, 180, pp. 442-451; Farzampour, A., Laman, J.A., Mofid, M., Behavior prediction of corrugated steel plate shear walls with openings (2015) Journal of Constructional Steel Research, 114, pp. 258-268; Farzampour, A., Mansouri, I., Lee, C.H., Sim, H.B., Hu, J.W., Analysis and design recommendations for corrugated steel plate shear walls with a reduced beam section (2018) Thin-Walled Structures, 132, pp. 658-666; Hitaka, T., Matsui, C., Experimental study on steel shear wall with slits (2003) Journal of Structural Engineering, 129 (5), pp. 586-595; Jiménez-Alonso, J.F., Sáez, A., Robust optimum design of tuned mass dampers to mitigate pedestrian-induced vibrations using multi-objective genetic algorithms (2017) Structural Engineering International, 27 (4), pp. 492-501; Khatibinia, M., Sadegh Naseralavi, S., Truss optimization on shape and sizing with frequency constraints based on orthogonal multi-gravitational search algorithm (2014) Journal of Sound and Vibration, 333 (24), pp. 6349-6369; Lee, C.H., Ju, Y.K., Min, J.K., Lho, S.H., Kim, S.D., Non-uniform steel strip dampers subjected to cyclic loadings (2015) Engineering Structures, 99, pp. 192-204; Lee, C.H., Kim, J., Kim, D.H., Ryu, J., Ju, Y.K., Numerical and experimental analysis of combined behavior of shear-type friction damper and non-uniform strip damper for multi-level seismic protection (2016) Engineering Structures, 114, pp. 75-92; Lee, C.H., Lho, S.H., Kim, D.H., Oh, J., Ju, Y.K., Hourglass-shaped strip damper subjected to monotonic and cyclic loadings (2016) Engineering Structures, 119, pp. 122-134; Lee, C.H., Woo, S.-K., Ju, Y.K., Lee, D.-W., Kim, S.-D., Modified Fatigue Model for Hourglass-Shaped Steel Strip Damper Subjected to Cyclic Loadings (2015) Journal of Structural Engineering, 141 (8); Liu, T., Zhang, Q., Zordan, T., Briseghella, B., Finite element model updating of canonica bridge using experimental modal data and genetic algorithm (2016) Structural Engineering International, 26 (1), pp. 27-36; Longo, A., Montuori, R., Piluso, V., Moment frames-concentrically braced frames dual systems: analysis of different design criteria (2016) Structure and Infrastructure Engineering, 12 (1), pp. 122-141; Luth, G., Krawinkler, H., McDonald, B., USC School of Cinema: An example of reparable performance based design (2008) Proc. of the 77th Annual Structural Engineers Association of California (SEAOC) Convention, , Structural Engineers Association of Southern California, Fulllerton, CA; Ma, X., Borchers, E., Peña, A., Krawinkler, H., Billington, S., Deierlein, G., (2010) ""Design and behavior of steel shear plates with openings as energy-dissipating fuses"", , Report No. 173, The John A.

This can lead to lower ductility and energy dissipation capacity of the SFTS. To address this problem, a replaceable shear link, acting as a ductile fuse at the mid length of deep beams, is proposed. SFTS with replaceable shear links (SFTS-RSLs) dissipate seismic energy through shear deformation of the link. In order to evaluate this proposal, buildings were designed to compare the seismic performance of SFTS-RSLs and SFTSs. Several sub-structures were selected from the design buildings and finite element models (FEMs) were established to study their hysteretic behavior. Static pushover and dynamic analyses were undertaken in comparing seismic performance of the FEMs for each building. The results indicated that the SFTS-RSL and SFTS had similar initial lateral stiffness. Compared with SFTS, SFTS-RSL had lower yield strength and maximum strength, but higher ductility and energy dissipation capacity. During earthquakes, SFTS-RSL had lower interstory drift, maximum base shear force and story shear force compared with the SFTS. Placing a shear link at the beam mid-span did not increase shear lag effects for the structure. The SFTS-RSL concentrates plasticity on the shear link. Other structural components remain elastic during seismic loading. It is expected that the SFTS-RSL will be a reliable dual resistant system. It offers the benefit of being able to repair the structure by replacing damaged shear links after earthquakes.

However, in cases, such as elevated (or scoured) RC pile-cap foundation typologies that are partially embedded, the piles may suffer large deflections under lateral loads, which make it difficult for them to remain in the elastic state. In this regard, the present study makes an in-depth analysis on the ductile behavior of elevated RC pile-cap foundations to explore potentials for seismic ductile design. A beam-on-nonlinear-Winkler-foundation model with or without the consideration of bond-slip effect at pile head/cap connections is built in accordance with quasi-static testing of a 2 × 3 elevated RC pile-cap foundation, and validated in various aspects, including the global force-displacement relationship, the failure mechanism, and the location of plastic hinges. The validation results indicate that the bond-slip effect is generally unremarkable and can be neglected for the modeling of studied elevated pile-cap foundations (EPFs). Two limit states and the corresponding ductility factors, named easy-to-repair and ultimate displacement ductility factors, are proposed for EPFs. Parametric pushover analyses are then performed to investigate the impact of structural and geotechnical parameters on the ductile behavior of real-scale 2 × 3 elevated RC pile-cap foundations embedded in homogeneous and multilayered cohesionless soils. The numerical results show considerable ductile capacities (with an average quantified as 2.77 and 4.05 for the easy-to-repair and ultimate displacement ductility factors, respectively) for elevated RC pile-cap foundations. Additionally, a mathematical relationship between displacement and curvature ductility factors is established for future ductility-based design practices. © 2018 American Society of Civil Engineers.","Ductility; Elevated RC pile-cap foundation; FEM; Parametric analysis; Pushover; Scour","Bridges; Ductility; Failure (mechanical); Finite element method; Pile driving; Pile foundations; Repair; Scour; Seismic design; Seismology; Beam on nonlinear winkler foundation models; Displacement ductility factors; Ductility-based designs; Geotechnical parameters; Mathematical relationship; Parametric -analysis; Pile caps; Pushover; Piles",,,,,"SLDRCE 15-B-05; National Natural Science Foundation of China, NSFC: 51778469","Funding for this study is partially provided by the National Natural Science Foundation of China (Grant 51778469) and the Ministry of Science and Technology of China (Grant SLDRCE 15-B-05).

The premise of the work is to identify the location and the severity of a sustained structural damage to the cables, measured solely by vibration response of a moving vehicle passing over the bridge. To this aim, new formulations of dynamic coupling between the vehicle and the bridge are developed, utilizing finite element (FE) approach and validated. Further, the proposed framework to obtain the Vehicle-Bridge Interaction (VBI) is extended to a large-scale cable-stayed bridge. Various damage cases, caused by a partial and incremental change in structural stiffness of cables, being representative of gradual sectional loss due to corrosion, are taken into account. A damage index based on the Empirical Mode Decomposition (EMD) scheme is presented, and through extensive numerical investigations, it is demonstrated that under certain vehicle parameters the vehicle vibration response not only is capable of identifying the suffered damage to the bridge, but also is able to identify the damage location, and further to assess its severity. The contributions of the work are fourfold: (1) Many of the existing studies only focus on the simplified models of the bridge based on a simply supported Euler–Bernoulli beam theory; however, this paper extends the VBI framework to a three-dimensional numerical model of a large-scale bridge structure, being rarely reported in the BHM context. (2) The validation of the technique is demonstrated through extensive numerical investigations on a statically indeterminate cable-stayed bridge. (3) Successful detection, localization and assessment of damage to the cables are obtained using realistic range of vehicle parameters without any bridge response measurements. (4) Through extensive parametric study, the significance of various parameters on the effectiveness of the proposed approach is carefully investigated and discussed. © 2020 Elsevier Ltd","Bridge Health Monitoring (BHM); Cable-stayed bridge; Damage identification; Vehicle-Bridge Interaction (VBI)","Cable stayed bridges; Corrosion; Damage detection; Seats; Signal processing; Structural analysis; Vehicles; Vibrations (mechanical); Bernoulli beam theory; Bridge health monitoring; Damage Identification; Empirical Mode Decomposition; Numerical investigations; Structural stiffness; Three-dimensional numerical modeling; Vehicle-bridge interaction; Bridge cables; bridge; computer simulation; damage mechanics; dynamic analysis; dynamic response; finite element method; identification method; numerical model; stiffness; structural analysis; structural response; vibration",,,,,"Commonwealth Scientific and Industrial Research Organisation, CSIRO; Japan Society for the Promotion of Science, JSPS; University of New South Wales, UNSW; University of Western Sydney, UWS","The authors wish to thank CSIRO's Digital Productivity business unit, Data61 for providing the research data.

This paper presents a novel, practical, cost-effective, and field test-based methodology using portable cameras and computer vision technologies to identify the lateral live load distribution factors for the existing highway bridges to perform load rating. By using a computer vision-based measurement method and traffic recognition, the girder deflection under live load can be monitored in a noncontact way and can be utilized to derive the load distribution. To verify the feasibility of the proposed approach, a comparative experimental study is conducted on a real-life pre-stressed concrete bridge with a set of conventional load tests and experiments in normal traffic. The results are compared with the conventional approach, such as simplified formulations recommended by AASHTO specifications, and the experimental method using the data from strain gauges and a calibrated finite element model (FEM). The comparative results show that the proposed approach can obtain very similar load distribution factors and bridge load rating factors both in a conventional load test and normal traffic. In comparison to the simplified formulation recommended by AASHTO specifications, the proposed approach can reflect the real-life structural properties and improve the load rating factor of AASHTO specifications by around 12%. In addition, as compared to the load-test-based approaches, such as using strain data and calibrated FEM, the proposed approach does not require traffic closure and a large amount of effort to deal with the load test and model updating. The bridge studied in this paper represents a very typical one from a large population of bridges that are part of the smart infrastructure. Such a practical approach will be practical and cost-effective for bridge load rating in smart cities. © 2020, Springer-Verlag GmbH Germany, part of Springer Nature.","Bridge distribution factor; Computer vision; Displacement measurement; Highway bridges; Load rating; Load test","Bridges; Cameras; Cost effectiveness; Electric power plant loads; Load testing; Prestressed concrete; Smart city; Specifications; Bridge load ratings; Computer vision technology; Conventional approach; Experimental methods; Load distributions; Portable monitoring; Smart infrastructures; Vision-based measurements; Computer vision",,,,,"2219; National Science Foundation, NSF; Division of Civil, Mechanical and Manufacturing Innovation, CMMI: 1463493; Türkiye Bilimsel ve Teknolojik Araştirma Kurumu, TÜBITAK","The financial support for this research was provided by U.S. National Science Foundation (NSF) Division of Civil, Mechanical and Manufacturing Innovation (Grant number 1463493).

Permanent magnet FSM (PMFSM) is capable of high torque density and applicable for high-speed application, however conventional PMFSM exhibits demerits of high PM volume, high torque ripples and significant stator flux leakage. In this paper, a novel consequent pole E-core stator PMFSM is proposed and compared with conventional topology utilising 2D finite-element analysis (2D-FEA). Finite-element analysis revealed that proposed design enhanced flux modulation effects by introducing flux bridges and flux barriers as a result reduced cogging torque by reducing 46.53% of the total PM volume, reduce torque ripples by reducing PM slot effects and reduce flux leakage utilising flux bridges in the stator. Furthermore, analytical model for flux linkages, cogging torque, mechanical torque, no load and on-load magnetic flux density (MFD) is developed for initial design of conventional and proposed model. 2D analytical methodologies resolve equivalent magnetic circuits for open-circuit flux linkages, Fourier analysis for cogging torque, Laplace equations for MFD and Maxwell stress tensor for mechanical torque. Finally, results obtained from 2D-FEA and analytical methodologies are validated and compared. © 2020 The Institution of Engineering and Technology.","finite element analysis; Fourier analysis; Laplace equations; magnetic circuits; magnetic flux; permanent magnet machines; permanent magnet motors; reluctance machines; rotors; stators; synchronous machines; torque","DC machinery; Electric network analysis; Fourier analysis; Magnetic circuits; Maxwell equations; Permanent magnets; Stators; Torque; 2D finite element analysis; Analytical methodology; Conventional topologies; Equivalent magnetic circuit; High-speed applications; Maxwell stress tensors; Permanent magnets (pm); Stator permanent magnet; Finite element method",,,,,,,,,,,,,,,,"Liu, Z.J., Li, J.T., Analytical solution of air-gap field in permanent magnet motors taking into account the effect of pole transition over slots (2007) IEEE Trans.

In this research, experimental, numerical and analytical studies were carried out to investigate the flexural performance of simply supported composite box girders with CSWs. Two 1:5 scale models of a real bridge were fabricated and tested, including one with concrete filled steel tubes and another with hollow steel tubes. The test results show that the two specimens have good ductility and failed in a ductile manner. The concrete filled inside steel tubes reduces the deflection and increases the yield load. The cross sections of the two specimens basically satisfy the “plane section assumption”. Finite element models were also developed for the two specimens and validated based on the experimental results. Afterwards, a parametric study was carried out with the validated finite element models, which shows that the steel ratios and the structure of bottom trusses strongly influences the flexural behavior. At last, a theoretical model is developed to calculate the bending moment of composite beams at the ultimate load. © 2020 The Authors","Composite box girder with corrugated steel webs and trusses; Flexural behavior; Flexural stiffness; Nonlinear analysis; Numerical analysis","Box girder bridges; Finite element method; Nonlinear analysis; Numerical analysis; Steel beams and girders; Trusses; Tubular steel structures; Analytical studies; Composite box girder; Concrete filled steel tube; Corrugated steel webs; Flexural behavior; Flexural performance; Flexural stiffness; Theoretical modeling; Concretes; composite; ductility; finite element method; numerical method; steel structure; stiffness; structural component",,,,,"JCYJ2014090216222; National Natural Science Foundation of China, NSFC: 51578323; China Postdoctoral Science Foundation: 2019M653085; Guangdong Science and Technology Department, GDSTC: 2012-02-025","This research is funded by the National Natural Science Foundation of China (Project No. 51578323 ), Guangdong Provincial Department of Science and Technology (Project No. 2012-02-025 ), Project funded by China Postdoctoral Science Foundation (Project No. 2019M653085 ) and Science and Technology Innovation Committee of Shenzhen (Project No. JCYJ2014090216222 ).",,,,,,,,,,"Chen, Y.Y., Dong, J.C., Xu, T.H., Composite box girder with corrugated steel webs and trusses – a new type of bridge structure (2018) Eng Struct, 166, pp. 354-362; Chan, C.L., Khalid, Y.A., Sahari, B.B., Hamouda, A.M.S., Finite element analysis of corrugated web beams under bending (2002) J Constr Steel Res, 58 (11), pp. 1391-1406; Mo, Y.L., Jeng, C.H., Krawinkler, H., Experimental and analytical studies of innovative prestressed concrete box-girder bridges (2003) Mater Struct, 36 (2), pp. 99-107; Jiang, R.J., Wu, Q.M., Xu, T.H., (2016), Effective flange width for composite box girder with corrugated steel webs.

A total of seven SRC columns with T-shaped steel skeleton were prepared and tested using a drop hammer impact system. The testing variables include the impact height, stirrup spacing and the axial compression ratio. The impact force time histories and lateral displacements at mid-span and quarter-span were recorded and analyzed. The experimental results indicated that the decrease of stirrup spacing resulted in a smaller lateral deflection. Axial load was also found to have a strong influence on the residual deflection of columns subjected to impact loading. In addition, the finite element analysis models, which considers the effects of strain rate of steel and concrete as well as the axial loads, were established to simulate the experiment. The FEA results are proved to agree well with that of experiment. The findings obtained from this study can facilitate the application of SRC columns in improving the impact-resistant performance of bridge and building columns. © 2020 Elsevier Ltd","Axial load; Dynamic behavior; Finite element simulation; Lateral impact; Steel reinforced column (SRC)","Axial loads; Columns (structural); Composite structures; Finite element method; Strain rate; Dynamic behaviors; Effects of strain rates; Experimental investigations; Finite element analysis model; Finite element simulations; Lateral impact; Steel reinforced; Steel reinforced concrete; Reinforced concrete; column; compression; experimental study; finite element method; impact; loading test; performance assessment; reinforced concrete; strain rate",,,,,"D20161305; National Natural Science Foundation of China, NSFC: 51978078; Natural Science Foundation of Hubei Province: 2016CFB604","The authors were particularly grateful for the financial support provided by the National Natural Science Foundation of China (Grant number 51978078 ), the Natural Science Foundation of Hubei Province of China (Grant 2016CFB604 ), and the Science Foundation of the Education Department of Hubei Province of China (Grant D20161305 ).

The proprietary software Comsol Multiphysics was used for this purpose, and the interface motion was captured by the Level-Set method. Good agreement was obtained between numerical and experimental results in the literature. The effects of the electric field strength, droplet size, oil phase permittivity, surface tension, bulk viscosity, water phase conductivity, and drop-interface distance were systematically assessed. Three coalescence modes were obtained: complete coalescence, including typical complete coalescence and complete coalescence with upheaval; partial coalescence, including typical partial coalescence and jet-like partial coalescence; and non-coalescence, including typical non-coalescence and breakup of bouncing-off droplet non-coalescence. The pressure gradients between the drop and the bridge rather than the sign of the pressure determined the coalescence. There is a critical non-dimensional drop-interface distance of electrocoalescence modes that has negligible dependence on the non-dimensional water phase conductivity. The ratio of the Weber Number (describing electric field effects) and the Ohnesorge Number (describing physical properties) was found to well describe the coalescence process. The outcome of this work is potentially useful for optimizing the design of compact and efficient oil-water separators. © 2019 Elsevier Ltd","Drop-interface coalescence; Electrocoalescence; Electrohydrodynamics; Interface; Level-set method","Drop breakup; Electrohydrodynamics; Interfaces (materials); Level measurement; Navier Stokes equations; Numerical methods; Viscosity; Coalescence and breakups; Direct current electric fields; Electric field strength; Electrocoalescence; Level Set method; Oil water separators; Proprietary software; Water/oil interfaces; Coalescence",,,,,"University of Leeds; National Natural Science Foundation of China, NSFC: 51506078, 51761145011; China Scholarship Council, CSC: 201606450040; State Key Laboratory of Heavy Oil Processing: SLKZZ-2017013","The financial support of National Natural Science Foundation of China (No. 51761145011 , and No. 51506078 ), China Scholarship Council (No. 201606450040 ), and State Key Laboratory of Heavy Oil Processing ( SLKZZ-2017013 ) for supporting the first author to carry out the research work at the University of Leeds is gratefully acknowledged.",,,,,,,,,,"Aryafar, H., Kavehpour, H.P., Electrocoalescence: effects of DC electric fields on coalescence of drops at planar interfaces (2009) Langmuir, 25, pp. 12460-12465; Aryafar, H., Kavehpour, H.P., Electrocoalescence fireworks (2010) Phys.

The authors in the companion paper [1] proposed a corrugated steel web with vertical or/and horizontal stiffeners to replace or shorten the length of concrete encasement. In parallel with experimental study described in the companion paper, this paper further investigates the shear performance of proposed stiffened corrugated steel webs by numerical and analytical methods. Firstly, finite element (FE) models considering material nonlinearity, welding residual stress, and geometric imperfection were established and validated against the experimental results. Then the effects of web thickness, corrugation depth, height and thickness of stiffeners on shear strength and failure modes were analyzed based on the validated FE models. Finally, both experimental and numerical shear strength were used to evaluate the applicability of existing calculation methods proposed by different scholars to predict the shear capacity of stiffened corrugated steel web. The comparisons reveal that calculation methods proposed by Hassanein & Kharoob [2] and Leblouba et al. [3] predict the shear capacity of pure corrugated steel web more accurately, and all existing calculation methods underestimate corrugated steel web with vertical stiffeners. Therefore, the analytical model for accurately predicting shear strength of stiffened corrugated steel web need to be developed, which will be investigated in subsequent studies. © 2019 Elsevier Ltd","Analytical models evaluation; Composite bridge; Finite element analysis; Parametric studies; Shear capacity; Stiffened corrugated steel web","Analytical models; Composite bridges; Finite element method; Forecasting; Numerical methods; Shear flow; Construction process; Corrugated steel webs; Geometric imperfection; Intermediate support; Material non-linearity; Parametric study; Shear capacity; Welding residual stress; Concretes",,,,,"110109039; National Natural Science Foundation of China, NSFC: 51308070","The authors gratefully thank the financial support of National Natural Science Foundation of China ( 51308070 ) and Transportation Science and Technology Project of Sichuan Province ( 110109039 ).",,,,,,,,,,"Wang, S., He, J., Liu, Y., Shear behavior of steel I-girder with stiffened corrugated webs (2019) Part I: Exp.

Reif, Jr., Department of Civil and Environmental Engineering, New Jersey Institute of Technology, Newark, NJ, United States","Ductile concrete materials, such as high-performance fiber-reinforced cementitious composites (HPFRCCs), are being considered as a new material that can be used in plastic hinge regions of buildings and bridges to reduce damage as compared to ordinary reinforced concrete. In flexure, a highly nonlinear plastic strain distribution of the primary tensile reinforcement is observed at dominant crack locations, leading to significant differences in plastic hinge length and behavior as compared to ordinary reinforced concrete flexural members. In this study, two-dimensional finite element models were validated with experimental results using a recently developed bond-slip constitutive model, which aids in simulating multiple damage states, such as yield and collapse level drift states. After validation, the modeling approach was used to study the plastic hinge region behavior of reinforced HPFRCC flexural members with variations in mechanical properties, boundary conditions, and geometric properties. The particular areas of interest were reinforcement yielding location, plastic strain distribution, and curvature localization region. New expressions were proposed to predict the equivalent plastic hinge length, Lp, using variables such as shear-span, tensile strength of HPFRCC, reinforcement ratio, yield strength of the reinforcement, boundary condition, and loading scenario. Proposed equations for plastic hinge length of reinforced HPFRCCs are incorporated into a mechanics-based approach to predict rotational capacity of flexural members. The analytical approach was also shown to estimate yield and nominal flexural strength with reasonable accuracy. The proposed methodology is compared with experimental results and expressions for plastic hinge length found throughout the literature for reinforced concrete and HPFRCC members. The results of the study will help practicing engineers and researchers simulate the performance of reinforced HPFRCC flexural members in a computationally efficient manner. © 2019 Elsevier Ltd","Finite element analysis; Fracture; HPFRCC; Plastic hinge length; Plastic rotation","Boundary conditions; Fiber reinforced materials; Finite element method; Fracture; High performance concrete; Plastic deformation; Steel beams and girders; Tensile strength; Computationally efficient; High performance fiber reinforced cementitious composites; HPFRCC; Multiple damage state; Plastic hinges; Plastic rotation; Reinforcement ratios; Tensile reinforcement; Reinforced concrete; ductility; experimental study; flexure; fracture initiation; model test; model validation; numerical model; reinforced concrete; structural component; tensile strength",,,,,,"The authors gratefully acknowledge the support of John A.

Corrosion pit-induced stress concentration accelerates the initiation of fatigue cracks, ultimately reducing the fatigue life of bridge sling. This paper proposes a critical region method to predict the fatigue life of notched steel wires. This method considers the critical distance and the average stress amplitude of notched specimen. Fatigue loading tests on various notched steel wires are performed to simulate the effects of corrosion pit morphologies on the performance of steel wires. The relationships between notch dimensions and the fatigue lives of specimens are discussed. Following that, a fine-mesh three-dimensional solid model of notched steel wire is established by finite element method. The stress concentration coefficients and the stress distribution near the notch root are investigated, and the critical distance is also determined according to the local stress gradient of notched steel wire. The critical region-based fatigue life prediction method is validated using experimental fatigue life results of notched steel wires. A good agreement is observed between the theoretical predictions and experimental observations. © 2019 Elsevier Ltd","Bridge engineering; Corrosion; Critical region method; Fatigue; Finite element method; Stress concentration","Bridges; Corrosion; Corrosive effects; Finite element method; Forecasting; Pitting; Steel corrosion; Stress concentration; Wire; Bridge engineering; Concentration coefficients; Corrosion process; Critical region; Fatigue life prediction; Notched specimens; Practical engineering; Three-Dimensional Solid Modeling; Fatigue of materials",,,,,"18ZDXK08; National Natural Science Foundation of China, NSFC: 51478050, 51778068; Changsha University of Science and Technology, CSUST: 18KC03; Hunan Provincial Innovation Foundation for Postgraduate: CX2018B524; National Key Research and Development Program of China, NKRDPC: 2015CB057705; Major State Basic Research Development Program of China; Training Program for Excellent Young Innovators of Changsha: kq1802012; Natural Science Foundation for Distinguished Young Scholars of Hunan Province: 2019JJ30024","The study reported here is financially supported from the National Natural Science Foundation of China (51478050 and 51778068), the state key development program for basic research of China (2015CB057705), Natural Science Foundation for Excellent Young Scholars of Hunan Province (2019JJ30024), Training Program for Excellent Young Innovators of Changsha (kq1802012), Key Disciplinary of Civil Engineering of Changsha University of Science and Technology (18ZDXK08), Hunan Provincial Innovation Foundation for Postgraduate (CX2018B524), and the Open Research Fund of Science and Technology Innovation Platform of Hunan Bridge Engineering Safety Control Technology and Equipment Engineering Research Center of CSUST (18KC03).

Then, using this model, we developed the numerical simulation analysis of the influence law of material damage deterioration on structural system performance under train load and revealed the fatigue evolution of the structural system. The results show that the beam remains in compressed status for the whole process, the track is in compression in the midspan and in tension at the beam end, and the tensile stress is larger near the shear groove under the double-track static load. Under the fatigue load, stiffness degradation of the structural system is not obvious, and integral rigidity of the structural system is dependent on the rigidity of the beam. Strength reduction of the materials caused stress redistribution of the structural system and had a larger effect on the stress of each layer of track structure than on the stress on the beam. The fatigue degradation of the cement-emulsified asphalt (CA) mortar layer material has a significant impact on the structural system, which directly affects structural layer stress variation with the fatigue loading cycle. © 2019 by the authors.","Ballastless track-bridge structural system; Cement-emulsified asphalt mortar; Constitutive model; Fatigue damage; Fatigue performance; Finite element analysis",,,,,,"2019JJ50800; National Natural Science Foundation of China, NSFC: 51578546, 51808558, 51820105014, U1434204; Central South University, CSU; China Power Investment Corporation, CPI: SHGF-18-50","This research was supported by the National Natural Science Foundation of China, grant numbers 51578546, U1434204, 51820105014, 51808558; the Natural Science Foundation of Hunan Province, China, grant number 2019JJ50800; the China Energy Investment Corporation, grant number SHGF-18-50.

A significant amount of research has focused on system identification using either dynamic or static measurements separately. Realizing the complementary relationship between static and dynamic measurements, traditional model updating methods adopt error functions to account for the residual between modeling and measured values for various types of measurements. Behavioral models may be inaccurate due to incomplete representation of modeling and measurement uncertainties. Furthermore, the normalization of error functions may bring additional uncertainty to the identification process. In this paper, an approach based on the model falsification method is proposed to combine both static and dynamic measurements with explicit consideration of both modeling and measurement uncertainties. A measurement selection strategy is also used to help detect abnormal measurements. The approach has been evaluated using a highway flyover bridge in Singapore. Dynamic measurement data include natural frequencies and mode shapes whereas static measurement data include inclinations, deflections and strains. By combining both static and dynamic measurements, this approach leads to falsification of additional model instances and obtains a more precise prediction of parameter values than approaches which interpret static measurements only. © 2019 Elsevier Ltd","Dynamic measurements; Finite element method; Multi-response; Parameter estimation; Static measurements; System identification","Crime; Electric measuring bridges; Finite element method; Identification (control systems); Load testing; Religious buildings; Uncertainty analysis; Complementary relationship; Dynamic measurement; Identification process; Measurement selections; Modeling and measurement; Multiresponse; Natural frequencies and modes; Static measurements; Parameter estimation; bridge; dynamic response; finite element method; in situ measurement; parameter estimation; static response; Singapore [Southeast Asia]",,,,,"Land Transport Authority - Singapore, LTA","This research was conducted at the Future Cities Laboratory at the Singapore-ETH Centre (SEC), Singapore .

First an analytical microstructure-based constitutive model is developed and numerically implemented in a general purpose finite element program. The analytical model takes into account explicitly the volume fractions, the material properties, and the spatial distribution of muscle's constituents by using homogenization techniques to bridge the different length scales of the muscle structure. Next, a numerical homogenization model is developed using periodic eroded Voronoi tessellation to virtually represent skeletal muscle microstructures. The eroded Voronoi unit cells are then resolved by finite element simulations and are used to assess the analytical homogenization model. The material parameters of the analytical model are identified successfully by use of available experimental data. The analytical model is found to be in very good agreement with the numerical model for the full range of loadings, and a wide range of different volume fractions and heterogeneity contrasts between muscle's constituents. A qualitative application of the model on fusiform and pennate muscle structures shows its efficiency to examine the effect of muscle fiber concentration variations in an organ-scale model simulation. © 2018 Elsevier Ltd","Constitutive modeling; Finite element analysis; Homogenization; Multiscale modeling; Muscle mechanics; Skeletal muscle","Constitutive models; Finite element method; Homogenization method; Microstructure; Muscle; Numerical methods; Numerical models; Volume fraction; Finite element simulations; Homogenization techniques; Multi-scale Modeling; Muscle mechanics; Numerical homogenization; Skeletal muscle; Skeletal muscle microstructures; Three-dimensional loadings; Analytical models; article; finite element analysis; human cell; mechanics; simulation; skeletal muscle cell; biomechanics; cytology; shear strength; skeletal muscle; Biomechanical Phenomena; Finite Element Analysis; Mechanical Phenomena; Muscle, Skeletal; Shear Strength",,,,,"Horizon 2020 Framework Programme, H2020; European Research Council, ERC: 636903","K.D. would like to acknowledge partial support from the European Research Council (ERC) under the European Union's Horizon 2020 research and innovation program (Grant Agreement No. 636903 ).",,,,,,,,,,"(2013), ABAQUS Dassault Systems Abaqus.

Conditions for producing the EC component perpendicular to the sample surface are investigated. A bridge-type probe including coplanar dual rectangular coils placed perpendicular to the test sample is designed to generate vertical EC component. Where there is delamination that is parallel to the sample surface, the vertical EC is perturbed, which results in an output signal in form of variable differential voltage of the coils. The principle of testing is verified by finite element analysis. Experiments are performed to test the validity of the proposed probe. The results of simulation and experiments show that peaks appear in output signal when the coils cross delamination and the distance between the two peaks of scanning signal can be used to quantitatively estimate the range of delamination. © 2018 Elsevier Ltd","Carbon fiber reinforced polymer; Delamination; Eddy current testing; Finite element analysis","Bridges; Delamination; Eddy current testing; Fiber reinforced plastics; Finite element method; Polymers; Probes; Reinforced plastics; Reinforcement; Bridge-type; Carbon fiber reinforced polymer; Differential voltage; Eddy current method; Output signal; Sample surface; Scanning signals; Test samples; Carbon fiber reinforced plastics",,,,,"National Natural Science Foundation of China, NSFC: 51277154; Specialized Research Fund for the Doctoral Program of Higher Education of China, SRFDP: 20120121110026","This work is supported by the National Science Foundation of China (Grant No. 51277154 ) and the Research Fund for the Doctoral Program of Higher Education (Grant No. 20120121110026).

Thus, it is of great significance to predict and control residual stresses induced by machining. This paper reviews the exploration of residual stress prediction models and three main methods for predicting residual stresses during the last few decades, i.e., empirical, analytical and finite element methods (FEMs), which are introduced in detail. Empirical methods together with effects of different cutting parameters and influential factors on residual stress are classified according to the published experimental results. They are convenient but have limited application range since they are usually established under certain conditions. Analytical methods, which aim at theoretically investigating the instantaneous stresses and temperature induced by machining and revealing how residual stresses are accumulated during the machining process, are explained and discussed according to the evolution histories of all existing approaches. It is observed that different approaches together with some relevant machining mechanisms are merged into the analyzing procedures. Finite element methods, which are adopted to intuitively simulate the machining process, are reviewed at the end of this paper. It is found that FEMs are helpful to study the influential factors and to bridge industry-relevant parameters, but have low efficiency, especially for the three-dimensional models. Advantages and disadvantages corresponding to every model are discussed and summarized. From comprehensive review, it can be concluded that developing a more accurate residual stress measuring method, establishing a more general analytical model and improving the computational efficiency of finite element analysis are greatly desired. © 2018, Springer Science+Business Media, LLC, part of Springer Nature.",,"Computational efficiency;

To bridge this research gap, this work proposed a data-driven learning algorithm to improve the prediction capacity of fatigue life by considering stochastic parameters of structures. In this new algorithm, the XFEM was firstly employed to generate a large amount of datasets that pair the structural responses with remaining fatigue life. Then, the back propagation neural network (BPNN) was employed to construct a fatigue life prediction model based on the XFEM datasets. Real-time prediction for the structural fatigue life was achieved using the constructed BPNN model without knowing the exact distribution functions of stochastic parameters. Several numerical examples were performed to evaluate the performance of the proposed algorithm. The analysis results demonstrate that the proposed data-driven algorithm can accurately predict the fatigue life of the structures with stochastic parameters. © 2020 Elsevier B.V.","Data-driven learning; Fatigue crack propagation; Stochastic model parameters; XFEM","Backpropagation; Distribution functions; Fatigue crack propagation; Forecasting; Large dataset; Parameter estimation; Predictive analytics; Stochastic models; Stochastic systems; Back-propagation neural networks; Data-driven learning algorithms; Exact distribution function; Extended finite element method; Fatigue crack growth analysis; Fatigue life prediction; Fatigue life prediction models; Remaining fatigue life; Fatigue of materials",,,,,"QN2020211; Natural Science Foundation of Hebei Province: A2020202017; Major Scientific and Technological Innovation Project of Shandong Province: 2019-JCJQ-00, 2019JZZY010820","This work is supported by the Natural Science Foundation of Hebei Province of China ( A2020202017 ), Youth Foundation of Hebei Education Department ( QN2020211 ), Major Scientific and Technological Innovation Project of Shandong Province of China (No. 2019JZZY010820 ) and Foundation Strengthening Program (No: 2019-JCJQ-00 ).",,,,,,,,,,"Shankar, S., Saw, K., Chattopadhyaya, S., Hloch, S., Investigation on different type of defects, temperature variation and mechanical properties of friction stir welded lap joint of aluminum alloy 6101-t6 (2018) Mater.

Hence, high-resolution FE models are meticulously developed in this paper to simulate barge collisions with a typical four-span continuous girder bridge. Numerical results highlight the importance of the gravity load for barge impact-induced responses. A simplified bridge model is proposed to improve computational efficiency. The proposed simplified method is found to be more accurate than that of the one-pier two-span (OPTS) model. Also, it is observed that although the peak impact force increases with impact energy, the impact-induced displacement does not always increase. It is attributed to the fact that the spectral characteristics of the impact force-time history have a significant influence on the impact-induced responses. To improve the impact resistance, three strengthening methods based on ultra-high-performance fiber-reinforced concrete (UHPFRC) are investigated and compared. It is found that strengthening columns with two-end UHPFRC jackets is superior to other strengthening methods when considering cost-benefit ratio. Finally, a multi-objective optimization design procedure is presented for the UHPFRC-strengthened columns. © 2020 Elsevier Ltd","Barge impact; Bridge structures; Dynamic behavior; FE modeling; Reinforced concrete (RC) column; UHPFRC-Based strengthening","Barges; Computational efficiency; Concrete bridges; Concrete construction; Cost benefit analysis; Fiber reinforced concrete; Finite element method; Multiobjective optimization; Continuous girder bridge; Cost benefit ratio; Dynamic behaviors; Peak impact forces; Simplified method; Spectral characteristics; Strengthening methods; Ultra-high-performance fiber-reinforced concrete; Ultra-high performance concrete; bridge; column; dynamic response; finite element method; numerical model; reinforced concrete; strength",,,,,"National Natural Science Foundation of China, NSFC: 51978258; Natural Science Foundation of Hunan Province: 2020JJ4186; National Key Research and Development Program of China, NKRDPC: 2018YFC0705400; Henan Province Science and Technology Innovation Talent Program: 2020RC3018","This research is supported by the National Key Research and Development Program of China (Grant Number: 2018YFC0705400 ), the National Natural Science Foundation of China (Grant Number: 51978258 ), the National Natural Science Foundation of Hunan Province (Grant Number: 2020JJ4186 ), and the Youth Science and Technology Innovation Talent Project of Hunan Province (GrantNumber: 2020RC3018 ).",,,,,,,,,,"AASHTO, (2009) Guide Specifications and Commentary for Vessel Collision Design of Highway Bridges, , second ed.

The accurate state assessment of such a process generally requires the nonlinear finite element analysis (FEA) to perform a stage-by-stage forward, cumulative calculation based on the principle of incremental superposition. This sort of calculation means that the structural equilibrium of any intermediate state of the process, referred to as a construction stage, must be accumulated from its previous construction loading history, which is susceptible to computational effort and divergence limitations. This paper overcomes these limitations by proposing a direct and fast method that is independent of the cumulative calculation in the analysis of any specified construction stage, in favour of the construction optimization design and uncertainty analysis. The unstrained assembly formats for the typical construction process of SAS bridges are established, and the elements with constant physical quantities as the characteristic parameters are used to describe the various structures, boundaries, loads and their changes during the construction. On this basis, an interactive analysis framework integrating the numerical iteration with the FEA is established to achieve an accurate equilibrium for the construction stages. An enhanced interval-genetic algorithm (IGA) is employed as the optimization engine to smoothly accelerate global convergence. The proposed framework is applied to an SAS bridge under construction, and the validity and performance of this approach are demonstrated by considering the in-field test data. © 2020 Elsevier B.V.","Construction process-independent simulation; Construction stage analysis; Interactive framework; Self-anchored suspension bridge; Unstrained assembly format","Construction; Genetic algorithms; Iterative methods; Uncertainty analysis; Construction loading; Construction optimization; Construction process; Interactive analysis; Interval genetic algorithm; Nonlinear finite element analyses (FEA); Self-anchored suspension bridge; Self-anchored suspensions; Bridges",,,,,"National Natural Science Foundation of China, NSFC: 51408249, 51878059; China Postdoctoral Science Foundation: 2019M653519; Natural Science Foundation of Shanxi Province: 2020JM-219","This work is supported by the Natural Science Foundation of Shannxi Province [No. 2020JM-219 ], the China Postdoctoral Science Foundation [No. 2019M653519 ] and the National Natural Science Foundation of China [No. 51878059 , 51408249 ].","This work is supported by the Natural Science Foundation of Shannxi Province [No. 2020JM-219], the China Postdoctoral Science Foundation [No. 2019M653519] and the National Natural Science Foundation of China [No. 51878059, 51408249].

A new design of microgripper based on a three-stage displacement amplification mechanism is utilized to magnify the piezoelectric actuator displacement. A bridge-type mechanism with a two-sided output port is serially connected with two consecutive lever mechanisms. The output motion on both sides is linearized by parallelogram mechanisms. The single-notch and double-notch circular flexural hinges were used in lever, bridge-type and parallelogram configuration. The displacement amplification and transmission mechanisms are arranged symmetrically to obtain stability of shape and compact layout of the entire microgripper. Analytical modeling was performed to establish an input and output displacement relationship. Finite Element Analysis (FEA) method was utilized to evaluate the performance of the microgripper. The design parameters of the microgripper were optimized through FEA method. The simulation results of the FEA method were validated through experimentation on the established design. The experimental results show that the total displacement amplification ratio of the microgripper is 12.76. The microgripper jaws have a high precision positioning accuracy. The microgripper also achieves a high-level working mode frequency of 1044 Hz, which is capable of accommodating rapid transient responses. © 2020 Elsevier Ltd","Compliant mechanism; Laser interferometry-based measurement;

The variation law of stress distribution of steel wire was analyzed, and its relationships with strength and stress concentration factor were studied through tensile test and finite element analysis. On this basis, the calculation model of yield strength and stress concentration factor of steel wire with pits was established. The influences of secondary pits on stress distribution and stress concentration factor of steel wire were also analyzed. The results showed that the strength of steel wire decreased gradually and the stress concentration factor increased with the increase of pit depth and the decrease of pit width. The change of pit clearance on the same side had no obvious effect on the strength and stress concentration factor of steel wire, but it had significant effect when located on the opposite side. The strength and stress concentration factor of steel wire with adjacent pits usually depended on the depth of the larger pits. The pits with depth to width ratio of 1 to 2 had the most significant effect on the stress concentration factor. Moreover, secondary pit would change the stress distribution, and the position of maximum stress changed from near the mouth to the bottom of the pit. The stress concentration factor of secondary pit was obviously higher than that of steel wire with only the primary pit. © 2019 Elsevier Ltd","Calculation model; Corrosion pit; Steel wire; Strength; Stress concentration factor","Bridge cables; Pitting; Polymer blends; Steel corrosion; Tensile testing; Yield stress; Calculation models; Corrosion pits; Steel wire; Strength; Stress concentration factors; Stress concentration",,,,,"National Natural Science Foundation of China, NSFC: NSFC-51078080","The financial support provided by National Natural Science Foundation of China under Grant Nos.

The Aizhai Bridge in China was selected as an example to demonstrate the numerical procedure for this framework. In the numerical analysis, the critical locations of the bridge were first determined by refined finite-element analyses, and 30,000 samples of random input parameters (random wind field and traffic flow) were generated. Subsequently, the corresponding dynamic stress responses at the critical locations of the bridge were obtained via a stress analysis approach under the combined action of random traffic and wind loads. Finally, the fatigue reliability of the bridge was assessed considering the influence of the wind load, traffic growth, and vehicle axle load growth. The results show that both the wind and traffic loads have certain effects on the fatigue reliability of the bridge. The upper and lower chords of the main truss at one-fourth of the span, which is sensitive to both the wind and vehicle loads, should be given more attention. © 2020 American Society of Civil Engineers.","Daily equivalent stress; Fatigue reliability analysis; Monte Carlo method; Random traffic; Wind loads","Aerodynamic loads; Automobile suspensions; Fatigue of materials; Monte Carlo methods; Stress analysis; Suspension bridges; Suspensions (components); Trusses; Wind stress; Analysis approach; Combined actions; Critical location; Dynamic stress; Equivalent stress; Fatigue reliability; Numerical procedures; Wind load; Reliability analysis",,,,,"Scientific Research Foundation of Hunan Provincial Education Department: 16B011; Applied Basic Research Key Project of Yunnan: 2015CB057701, 2015CB057706; National Natural Science Foundation of China-Yunnan Joint Fund, NSFC-Yunnan Joint Fund: 51678079, 51778073, 51822803, 51978087; Outstanding Youth Science Fund of Scientific and Technological Innovation from Pingdingshan; National Science Fund for Distinguished Young Scholars: 2018JJ1027","This work described in this paper is supported by the Key Basic Research Project (973 project) of PR China, under Contract Nos. 2015CB057701 and 2015CB057706.

Current design codes on steel arch bridges do not provide complete and adequate methodologies for the buckling design since they are based on linear buckling analyses, whose predictions in many cases overestimate the actual bridge capacity. In the present paper, a numerical procedure is implemented with the purpose to derive simple analytical expressions for the evaluation of critical axial force in network arch bridges. The proposed study is developed by means of progressive analyses, in which at first variability screening analysis is developed to identify worst instability scenarios with respect to all geometrical and mechanical characteristics in typical allowable ranges. Subsequently, explicit parametric analyses are developed to identify instability curves for several bridge configurations. The validity of the formulation is verified by means of comparisons with advanced analyses based on the FEM. The proposed results in terms of buckling curves may help the designer to achieve a proper estimation of the critical buckling load without developing sophisticated and complex nonlinear analyses. © 2019, Korean Society of Steel Construction.","Buckling; Critical buckling force; Design methodology; Finite element method; Network arch bridges; Nonlinear analysis","Arches; Buckling; Finite element method; Nonlinear analysis; Steel bridges; Analytical expressions; Critical buckling force; Critical buckling loads; Design Methodology; Linear buckling analysis; Mechanical characteristics; Network arch bridges; Parametric -analysis; Arch bridges",,,,,,,,,,,,,,,,"(2004) AASHTO LRFD bridge design specifications, , 3, American Association of State Highway and Transportation Officials (AASHTO), Washington (DC; Barbero, E.J., (2010) Introduction to composite materials design, , 2, Taylor & Francis, New York; Bradford, M.A., Pi, Y.-L., A new analytical solution for lateral-torsional buckling of arches under axial uniform compression (2012) Engineering Structures, 41, pp. 14-23; Bradford, M.A., Pi, Y.-L., Liu, A., Out-plane elastic-plastic buckling strength of high-strength steel arches (2018) Journal of Structural Engineering, 144 (6), p. 04018053; Bruno, D., Lonetti, P., Pascuzzo, A., An optimization model for the design of network arch bridges (2016) Computers & Structures, 170, pp. 13-25; Bruno, D., Lonetti, P., Pascuzzo, A., A numerical study on network arch bridges subjected to cable loss (2018) International Journal of Bridge Engineering (IJBE), 6 (2), pp. 1-19; (2018) COMSOL multiphysics reference manual, , COMSOL AB, Stockholm; De Backer, H., Outtier, A., Van Bogaert, P., Buckling design of steel tied-arch bridges (2014) Journal of Constructional Steel Research, 103, pp. 159-167; Eurocode 3: Design of steel structures (1995) Part 1-1: General Rules and Rules for Buildings; (2006) Eurocode 3: Design of Steel Structures, , Steel bridges).

The model takes into account critical parameters, namely, fire scenario, fire exposure length, load level, numbers of longitudinal stiffeners in web and bottom flange and web pattern, that influence fire performance of bridges. A three dimensional finite element model, developed in the computer program ANSYS, is applied to model the fire response of composite box bridge girders. The finite element model is validated by comparing predicted sectional temperatures and deflections from the model with fire test data generated from a test on box bridge girder. The applicability of the numerical model in practical application is illustrated through numerical analysis on a composite box bridge girder subjected to simultaneous structural loading and fire exposure. Results from the numerical study clearly show that fire severity, fire exposure length, load level, number of longitudinal stiffeners and web slenderness have significant influence on the fire resistance of composite bridge girders. Provision of longitudinal stiffeners can result in lower deflections; thus enhancing fire resistance. Further, inclined web (configuration) incorporated into sectional shape can enhance fire resistance of composite box bridge girders. © 2019 Elsevier Ltd","Bridge fires; Composite box bridge girders; Finite element analysis; Fire resistance; Thermo-structural analysis","Beams and girders; Composite bridges; Finite element method; Highway bridges; Numerical models; Plate girder bridges; Bridge girder; Fire performance; Fire scenarios; Fire test datum; Longitudinal stiffener; Structural loading; Thermo-structural analysis; Three dimensional finite element model; Fire resistance",,,,,"Michigan State University, MSU; National Natural Science Foundation of China, NSFC: 51308056, 51878057; Ministry of Transport of the People's Republic of China, MOT: 2011318812970; Southeast University, SEU; Fundamental Research Funds for the Central Universities: 310821172003; Natural Science Basic Research Program of Shaanxi Province: 2018JM5018","The authors wish to acknowledge the support from Ministry of Transport of the People's Republic of China (Grant No. 2011318812970 ) and the support from Natural Science Foundation of China (Grant No. 51878057 and No. 51308056 ), National Science Basic Research Plan in Shaanxi Province of China (Gran No. 2018JM5018 ), Research fund for Central Universities of China (Grant No. 310821172003 ), Michigan State University and Southeast University .

The curves are used to evaluate the buckling and ultimate collapse behaviour of these structural elements, and furthermore forming the input data to analytical progressive collapse methods for large scale box girder structures such as ships. This paper develops a novel analytical method that predicts the load-shortening curve of plates and stiffened panels under cyclic in-plane load. This provides the framework to account for load reversals in an enhanced cyclic progressive collapse method. A parametric study using nonlinear finite element analysis is completed to investigate the characteristic behaviour of simply supported plates under cyclic compression and tension. The investigation covers a range of aspect ratios and slenderness ratios typical for ship-type structures. Single-cycle and ten-cycle loading protocols are applied, which demonstrate progressive reduction in strength and stiffness together with a response convergence after several cycles. An analytical method to predict multi-cycle load-shortening behaviour is then derived using a response and updating rule based on the observed characteristics from the parametric study. A validation of the analytical method is performed on a range of unstiffened plates and stiffened panels under various cyclic loading protocols. A good comparison with the results of finite element analysis is obtained, which confirms the validity of the proposed analytical method. © 2019 Elsevier Ltd","Buckling; Collapse; Cyclic loading; Nonlinear finite element analysis; Ship structures; Ultimate strength","Aspect ratio; Box girder bridges; Buckling; Cyclic loads; Nonlinear analysis; Plates (structural components); Ships; Stress-strain curves; Structural dynamics; Structural panels; Buckling and collapse; Collapse; Non-linear finite-element analysis; Nonlinear stress-strain relationship; Ship structure; Simply supported plates; Strength and stiffness; Ultimate strength; Finite element method; analytical framework; buckling; collapse; cyclic loading; finite element method; prediction; reinforcement; strength; vessel",,,,,,,,,,,,,,,,"20th, I.S.S.C., ultimate strength.

Finite element models were developed with the capability to accurately replicate the experimental results of the box section members under combined compression and bending. Extensive parametric studies were carried out to examine the global buckling behaviour of welded high strength steel box section members with a wide range of dimensions and member slenderness and steel grades of S460, S690 and S960 and subject to varying combinations of compression and bending. The effects of residual stresses and ultimate tensile strength-to-yield strength ratio on the global buckling behaviour of those members were investigated. The applicability of existing design rules to welded high strength steel box section members subject to combined compression and bending was evaluated using the results from parametric studies and the available experimental results in literature. The European, American and Australian standards provide conservative strength predictions for the structures. More accurate and safe strength predictions can be obtained based on European standard using the suggested column curves for the members while the design methods in Australian and American standards are safely applicable to the members. © 2019 Elsevier Ltd","Combined compression and bending; Design; Finite element modelling; High strength steel; Welded box section member","Box girder bridges; Buckling; Compressive strength; Design; Finite element method; Tensile strength; Welding; Australian standards; Box section; Buckling resistance; European Standards; Finite element modelling; Strength prediction; Ultimate tensile strength; Yield strength ratios; High strength steel",,,,,"Hong Kong Polytechnic University, PolyU: 1- ZE50 /GYBUU","The authors are grateful for the support from the Chinese National Engineering Research Centre for Steel Construction (Hong Kong Branch) at The Hong Kong Polytechnic University .

A real-time control system emulates the interaction between numerical substructures, which replace subparts having well-established computational models, and physical substructures tested in the laboratory. In this context, state-space modeling, which is quite popular in the community of automatic control, offers a computationally cheaper alternative to the finite-element method for implementing nonlinear numerical substructures for fast-time hybrid simulation, that is, with testing timescale close to one. This standpoint motivated the development of a computational framework based on partitioned time integration, which is well suited for hard real-time implementations. Partitioned time integration, which relies on a dual assembly of substructures, enables coupling of state-space equations discretized with heterogeneous time step sizes. In order to avoid actuators stopping at each simulation step, the physical substructure response is integrated with the same rate of control system, whereas a larger time step size is allowed on the numerical substructure compatibly with available computational resources.

CFST trusses have been increasingly used in large-scale structures such as towers, bridge girders, piers and arch ribs. The compression and flexural behaviour of CFST trusses are greatly improved compared to hollow tubular trusses due to the concrete infill in chords. With the complex configuration, nonlinear material interaction and sophisticated construction process, initial imperfections may largely affect the strength and stability of a CFST truss structure. Relevant studies in the past mostly focused on one single type of imperfection with assumed magnitude in CFST member whilst in reality a variety of combinations of steel and concrete imperfection exist. This paper develops a nonlinear analysis formwork with the reliability analysis of CFST truss with random imperfections based on on-site measurement data and Monte-Carlo (MC) simulations. Advanced nonlinear finite element analysis (FEA) that can account for the material interaction and confinement in CFST trusses is established and validated by reported test data. The flexural behaviour of CFST trusses with deterministic and probabilistic initial imperfections are evaluated and compared, based on which the reliabilities and related system resistance factors in regards to random initial imperfections are proposed. © 2019 Elsevier Ltd","Concrete-filled steel tubes (CFST); Monte-carlo simulation; Random initial imperfections; Structural reliability; Truss structures","Arch bridges; Beams and girders; Concretes; Intelligent systems; Monte Carlo methods; Nonlinear analysis; Trusses; Tubular steel structures; Complex configuration; Concrete-filled steel tubes; Concrete-filled steel tubular; Initial imperfection; Large scale structures; Nonlinear finite element analyses (FEA); Structural reliability; Truss structure; Reliability analysis",,,,,"University of Sydney; National Natural Science Foundation of China, NSFC: 51838008","The research reported in this paper is supported by the National Natural Science Foundation of China (NSFC) (No. 51838008 ) and the Early Career Research Grant of Faculty of Engineering and IT, The University of Sydney.

The most common defects of these components are the voids and delamination, for which the Active Transient Thermography is one of the most reliable Non-Destructive Testing methods. However, a systematic and scientific insight on the thermal phenomena involved on Active Transient Thermography is needed to optimize the Non-Destructive Testing inspection parameters. Several representative case studies were experimentally tested and numerically simulated. For the case studies, samples of the polymeric material Nylon PA-12 were produced by Fused Deposition Modelling. The commercial code ANSYS is used for the calculation with the Finite Element Method of the thermal transient problem, using a numerical model which includes the three primary modes of heat transfer: conduction, convection, and radiation. Numerical simulation allowed a deeper insight of the thermal phenomena involved in the Non-Destructive Testing inspection, and it proves to be a useful tool for the selection of Non-Destructive Testing parameters. © 2019 Elsevier Ltd","Active thermography; Additive manufacturing; ANSYS; Numerical simulation; Radiation","3D printers; Additives; Bridge decks; Computer simulation; Fused Deposition Modeling; Heat radiation; Heat transfer; Inspection; Numerical methods; Numerical models; Thermography (imaging); Active thermography; ANSYS; Fused deposition modelling; Non destructive testing; Nondestructive testing method; Representative case; Simulation and validation; Transient thermography; Nondestructive examination",,,,,"Fundação para a Ciência e a Tecnologia, FCT; Ministério da Ciência, Tecnologia e Ensino Superior, MCTES: UID/EMS/00667/2019; Instituto Nacional de Ciência e Tecnologia para Excitotoxicidade e Neuroproteção, INCT-EN; European Regional Development Fund, FEDER; Programa Operacional Temático Factores de Competitividade, POFC","Authors gratefully acknowledge the funding of Project POCI-01-0145-FEDER-016414 (FIBR3D), cofinanced by Programa Operacional Competitividade e Internacionalização and Programa Operacional Regional de Lisboa , through Fundo Europeu de Desenvolvimento Regional (FEDER) and by National Funds through Fundação para a Ciência e a Tecnologia (FCT - MCTES).

For modeling these coupled processes with the finite element method, accurate descriptions of both the mechanical and the thermal responses of the material, as well as their interaction, are needed. Conventional material modeling employs empirical macroscopic constitutive relations but does not account for the actual thermo-mechanical mechanisms occurring at the microscopic level. However, the consideration of the latter might be crucial to obtain accurate predictions and a complete understanding of the underlying physics. In this work we describe a fully coupled implicit thermo-mechanical framework for crystal plasticity simulations. This framework includes thermal strains, temperature dependency of the crystal behavior and heat generation by dissipation due to plastic slip and allows the use of large deformation steps thanks to the implicit integration of the governing equations. Its use within computational homogenization simulations allows to bridge the plastic deformation and temperature gradients at the macroscopic scale with the microscopic slip at the grain scale. A series of numerical examples are presented to validate the approach. © 2019 Elsevier Ltd.","Crystal plasticity; Finite elements; Polycrystal homogenization; Thermo-mechanical coupling","Finite element method; Plasticity; Computational homogenization; Constitutive relations; Conventional materials; Crystal plasticity; Crystal plasticity models; Manufacturing process; Temperature dependencies; Thermo - mechanical couplings; Mechanisms",,,,,"China Scholarship Council, CSC: 201504890009, DPI2015-67667-C3-1-R, DPI2015-67667-C3-2-R","J.

The proposed approach relies on a new packing/relocation-based reconstruction algorithm to synthesize realistic 3D representative volume elements (RVEs) of CFRP. A non-iterative mesh generation algorithm is then employed to create high-quality finite element models of each RVE. The failure response of CFRP is simulated using ductile and cohesive-contact damage models for the epoxy matrix and along fiber-matrix interfaces, respectively. In addition to studying the impact of fiber misalignments, this computational framework is employed to investigate the effect of cross-sectional geometry of fibers (circular versus oval shaped) on the strength, ductility, and toughness of CFRP subject to tensile and compressive loads applied transverse to the fibers direction. © 2018, Springer-Verlag GmbH Germany, part of Springer Nature.","Cross-sectional geometry; Damage; Fiber reinforced composite; Finite element; Misalignment","Alignment; Bridge decks; Carbon fiber reinforced plastics; Communication channels (information theory); Fiber reinforced plastics; Fibers; Finite element method; Iterative methods; Mesh generation; Polymers; Reinforced plastics; Reinforcement; Carbon fiber reinforced polymer; Crosssectional geometry; Damage; Fiber reinforced composites; Mesh generation algorithm; Misalignment; Reconstruction algorithms; Representative volume element (RVE); Failure (mechanical)",,,,,"Air Force Office of Scientific Research, AFOSR: FA9550-17-1-0350","Acknowledgements This work has been supported by the Air Force Office of Scientific Research (AFOSR) under Grant Number FA9550-17-1-0350 and the Ohio State University Simulation Innovation and Modeling Center (SIMCenter) through support from Honda R&D Americas, Inc.

Although many simulation models are available for the individual effects of earthquake and tsunami hazards on bridges, there are limited modeling approaches for predicting damage from sequential earthquake and tsunami hazards. A bridge modeling approach, which includes soil-foundation-structure interaction effects, is developed within the finite-element framework OpenSees to quantify sequential earthquake and tsunami-induced damage. Multihazard interaction diagrams that relate earthquake and tsunami intensity measures to bridge system damage show that the residual effects of earthquake loading on the bridge system reduce resistance to subsequent tsunami loading. © 2019 American Society of Civil Engineers.","Bridges; Earthquake; Finite element; Multihazard; OpenSees; Soil-structure interaction; Tsunami","Bridges; Finite element method; Hazards; Soil structure interactions; Soils; Tsunamis; Earthquake and tsunamis; Earthquake loadings; Interaction diagram; Large earthquakes; Multihazard; Opensees; Socioeconomic loss; Soil-foundation-structure interactions; Earthquakes",,,,,,,,,,,,,,,,"Alam, M.S., Barbosa, A.R., Scott, M.H., Cox, D.T., Lindt De Van, J.W., Development of physics-based tsunami fragility functions considering structural member failures (2018) J.

The method utilizes model-based damage identification that involves three major steps: (1) efficient basis functions - extracted from finite-element (FE) models prior to real-time identification; (2) partial least-squares regression (PLSR) analyses; and (3) the fusion of different types of structural responses into damage indicator. By treating local damages as equivalent vertical loads and then cross-referencing global (inclinations) and local (strain) data, the hidden damage information in bridge structures can be detected and localized in a timely fashion, even in the presence of unknown temperature variation as well as vehicle loads. Inclinations alone cannot reflect local damages, but by fusing inclinations and strains (that represent local damage) into the proposed damage indicator, local damages can be identified. Numerical simulations on a medium-span continuous bridge demonstrate that the proposed method is insensitive to measurement noise and some common modeling errors, revealing the potential of real-time damage identification in bridge SHM applications. © 2018 American Society of Civil Engineers.","Damage indicator; Finite-element model; Partial least-squares regression; Real-time damage identification; Structural health monitoring; Temperature variation","Finite element method; Least squares approximations; Numerical methods; Strain; Structural health monitoring; Temperature distribution; Bridge structural health monitoring; Damage Identification; Damage indicator; Partial least squares regression; Partial least squares regressions (PLSR); Real-time identification; Structural response; Temperature variation; Damage detection",,,,,"SLDRCE15-A-02; China Scholarship Council, CSC: 201506260124, SLDRCE13-MB-01","The authors acknowledge support for the work reported in this paper from State Key Laboratory of Disaster Reduction in Civil Engineering, Tongji Univ.

This common belief was recently put under question by a family of experiments that displayed full gate-voltage-induced suppression of critical current in superconducting all-metallic gated nanotransistors. To date, the microscopic origin of this phenomenon is under debate, and trivial explanations based on heating effects given by the negligible electron leakage from the gates should be excluded. Here, we demonstrate the control of the supercurrent in fully suspended superconducting nanobridges. Our advanced nanofabrication methods allow us to build suspended superconducting Ti-based supercurrent transistors which show ambipolar and monotonic full suppression of the critical current for gate voltages of VG C ≃ 18 V and for temperatures up to ∼80% of the critical temperature. The suspended device architecture minimizes the electron-phonon interaction between the superconducting nanobridge and the substrate, and therefore, it rules out any possible contribution stemming from charge injection into the insulating substrate. Besides, our finite element method simulations of vacuum electron tunneling from the gate to the bridge and thermal considerations rule out the cold-electron field emission as a possible driving mechanism for the observed phenomenology. Our findings promise a better understanding of the field effect in superconducting metals. © 2020 American Chemical Society.","Dayem bridge; Field effect; Josephson effect; Supercurrent transistor; Suspended metallic nanowire","Electron tunneling; Electron-phonon interactions; Nanotransistors; Threshold voltage; Titanium; Critical temperatures; Device architectures; Electrostatic field effects; Finite element method simulation; Insulating substrates; Nano-fabrication methods; Standard conditions; Superconducting metals; Electrons",,,,,"Horizon 2020 Framework Programme, H2020: 800923; H2020 Marie Skłodowska-Curie Actions, MSCA: 796603","The authors acknowledge the Horizon 2020 innovation programme under Grant Agreement No. 800923-SUPERTED and Marie Skłodowska-Curie grant agreement EuSuper No. 796603.

The dynamic responses of reinforced concrete bridge double-column and reliability analysis under vehicle collision were carried out in the present work. Firstly, the establishment of a detailed finite element cast-in-place column model was conducted to verify the rationality of reinforced concrete model under impact loading. Then, the numerical model of vehicle collision on double-column bridge was established. The parameters of vehicle velocity, section size, pier height and concrete strength were investigated respectively. The results show that the failure modes of punching shear, shear cracks and diagonal shear are mainly dominated by the vehicle velocity and the section size of pier. The multiple sections of pier show a high stress state under vehicle collision. The peak shear forces at sections of bottom and impact area increase gradually with the increase of concrete strength, and it's remarkable that concrete strength has no noticeable effect on the shear force of other sections under vehicle collision. Lastly, based on the reliability theory, the shear failure probability of pier under vehicle collision was analyzed by Monte Carlo method. The factors of vehicle velocity, vehicle mass, section size of pier and concrete strength were investigated respectively. It provides a new method for the reliability analysis of vehicle collision on bridge. © 2020 Elsevier Ltd","Dynamic responses; Numerical model; Reinforced concrete; Reliability analysis; Vehicle collision","Accidents; Cast in place concrete; Concrete construction; Disasters; Dynamic response; Losses; Monte Carlo methods; Piers; Reinforced concrete; Reliability theory; Shear flow; Vehicles; Velocity control; Column modeling; Concrete strength; Diagonal shear; Double column bridge; Impact loadings; Punching shear; Vehicle collisions; Vehicle velocity; Reliability analysis; bridge; collision; column; dynamic response; failure analysis; finite element method; Monte Carlo analysis; reinforced concrete; reliability analysis; strength",,,,,"National Natural Science Foundation of China, NSFC: 51421005, 51978022; National Key Research and Development Program of China, NKRDPC: 2018YFC1504302","The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This research was supported by the National Natural Science Foundation of China (Nos. 51978022 and 51421005 ) and the National Key Basic Research and Development Program of China (No. 2018YFC1504302 ).","The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This research was supported by the National Natural Science Foundation of China(Nos. 51978022 and 51421005) and the National Key Basic Research and Development Program of China (No. 2018YFC1504302).",,,,,,,,,"EI-Tawil, S., Severino, E., Fonseca, P., Vehicle collision with bridge piers (2005) J Bridge Eng, 10 (3), pp. 345-353; Tsang, H.H., Lam, N.T.K., Collapse of reinforced concrete column by vehicle impact (2008) Comput-Aided Civ Inf, 23, pp. 427-436; Hartil, I.E., Shaaban, A.M., Gesund, H., Valli, G.Y.S., Wang, S.T., United States bridge failures 1951–1988 (1990) J Perform Constr Fac, 4, pp. 272-277; Wardhana, K., Hadipriono, F.C., Analysis of recent bridge failures in the United States (2003) J Perform Constr Fac, 17 (3), pp. 144-150; Chopra, A.K., (2001), Dynamic of structures: Theory and applications to earthquake engineering. 2nd ed. englewood Cliffs(NJ): Prentice-Hall;; (2010), Eurocode 1: actions on structures-Part 1-7: general actions–accidental actions.

Unfortunately, features of non-prismatic beams lead their modeling to be a non-trivial task: (i) variations of both cross-section area and second moment of area impede an easy computation of analytical solutions compelling to use approximated methods; (ii) stress distributions in prismatic and non-prismatic beams are substantially different, as proved by analytical results available since the beginning of the past century; and (iii) the peculiar stress distribution in non-prismatic beams entails complicated constitutive relations, as highlighted in recent publications. Usually, commercial software does not properly account for all the features of non-prismatic beams, leading to inconsistent structural analyses, erroneous estimations of the stress distribution, and -consequently- coarse predictions of the structural element strength. The present paper proposes a strategy to effectively overcome the above-mentioned problems. We derive an accurate analytical model for 2D non-prismatic beams, able to handle the non-trivial stress distribution and the complicated constitutive relations. Thereafter, we compute both homogeneous and particular solutions using the symbolic calculus software MAPLE and we analytically define the Finite Element (FE) stiffness matrix for a planar, symmetric, linearly-tapered beam. Finally, we compare the proposed FE and SAP2000 solutions, considering several beams with different geometries, loads, and constraints. Numerical results highlight the reliability of the proposed modeling strategy, since the resulting FE consistently handles all the critical issues of non-prismatic beams with an extremely low computational cost. Conversely, SAP2000 solution remarks the need of ad hoc analysis tools and modeling strategies to be used for the design of non-prismatic structural elements. © 2020 Elsevier Ltd","Haunch beams; Non-prismatic beam FE; Reinforced concrete frames; Stiffness matrix analytical definition; Tapered beam model","Analytical models; Bridges; Calculations; Composite structures; Finite element method; Stiffness; Stress concentration; Structural analysis; Analytical results; Commercial software; Computational costs; Constitutive relations; Cross-section area; Different geometry; Particular solution; Structural elements; Stiffness matrix; analytical method; bridge; finite element method; loading test; reliability analysis; stiffness; structural analysis",,,,,"Università degli Studi di Pavia","F.

Three-dimensional finite element models are developed for both CFRP-strengthened and unstrengthened CHS gap K-joints to calculate the SCFs, which are verified using previous test data. A parametric study is then carried out to explore the effects of various parameters (11 independent CFRP strengthening parameters and 5 basic geometric parameters describing the steel K-joints) on the efficiency of CFRP strengthening in terms of SCF reduction coefficient ψ. It is found that ψ is primarily affected by the CFRP relative reinforcement rates, the CFRP-to-steel tensile modulus ratios, the adhesive modulus, and non-dimensional geometric parameters. Through regression analyses, parametric formulae are finally developed for estimating ψ at six critical hot spots in CFRP-CHS K-joints under balanced axial loading. The proposed parametric formulae agree well with the experimental data. © 2020 Elsevier Ltd","Carbon fibre reinforced polymer; CFRP strengthening; Circular hollow section gap K-joint; Finite element analysis; Parametric formulae; SCF reduction coefficient","Adhesives; Beams and girders; Bridge decks; Carbon fiber reinforced plastics; Carbon fibers; Finite element method; Regression analysis; Reinforcement; Strengthening (metal); Stress concentration; Carbon fibre reinforced polymer; Cfrp strengthening; K-joint; Parametric formulae; Reduction coefficient; Tensile strength; computer simulation; finite element method; mathematical analysis; numerical model; polymer; regression analysis; stress field; tensile stress; three-dimensional modeling",,,,,"Shanghai Municipal Education Commission: 2019010301","The authors are grateful for the financial support from Shanghai Civil Engineering Peak Discipline Program of Shanghai Municipal Education Commission (No. 2019010301 ).",,,,,,,,,,"Wardenier, J., Packer, J.A., Zhao, X.L., van der Veget, G.J., Hollow sections in structural applications (2010), 2nd ed.

The two types of cutout are incorporated in two closely spaced diaphragms with distance of 6 m and at the same transverse location on a real bridge, allowing simultaneous stress measurement under random traffic flows. The research was conducted on the Pingsheng Bridge in Southern China, a self-anchored suspension bridge with a main span of 350 m and a steel box girder with orthotropic steel bridge decks (OSBD). Results of the study reveal that the two types of cutout geometry present high stress response and severe stress concentration at the floorbeam (FB) cutout, and that the excessively large stress at the original FB cutout contributes greatly to the early cracks of this detail. Compared to the original cutout geometry, the new cutout geometry with large radius increases the stress level at the FB cutout, resulting in a further low fatigue life at this detail. Meanwhile, the new cutout geometry also deteriorates the fatigue resistance at the rib-to-floorbeam (RF) weld connection, particularly at the detail of rib wall at cutout, where the stress level is significantly increased and its fatigue life becomes substantially lower than the design life of 100 years. In addition, the new cutout geometry only slightly improves the out-of-plane distortion under direct wheel loading, and the in-plane stress still dominates the total stress at the FB cutout. Since the new cutout geometry weakens the FB web, the total stress at FB cutout will increase due to the increased in-plane stress. The research also finds that if the free edge of cutout did not satisfy the fabrication requirement per the AASHTO LRFD, category B is suggested for fatigue evaluation at the FB cutout, which is confirmed by the observed fatigue life of the original FB cutout on the real bridge. It is concluded that the new cutout geometry lowers the fatigue resistance both at the FB cutout and at the RF weld connection, hence it will no longer be recommended to retrofit the present bridge in the future. © 2019 Elsevier Ltd","Fatigue life; Field tests; Finite-element analysis; Floorbeam cutout; Orthotropic steel deck; Random traffic flows; Rib-to-floorbeam weld connection; Steel bridge","Box girder bridges; Bridge decks; Finite element method; Geometry; Steel bridges; Stress analysis; Welds; Field test; Floorbeam cutout; Orthotropic steel decks; Random traffic flows; Rib-to-floorbeam weld connection; Fatigue of materials; bridge; fatigue; field method; finite element method; loading; shear stress; structural response; China",,,,,"201903; NTF18014; National Natural Science Foundation of China, NSFC: 51878269","This work was supported by the National Natural Science Foundation of China [grant number 51878269 ]; the STU Scientific Research Foundation for Talents of China  [grant number  NTF18014 ]; and the Open Foundation of Key Laboratory of Structure and Wind Tunnel of Guangdong Higher Education Institutes of China [grant number  201903 ], to which the writers gratefully appreciate.

A case was found in the project of Tianjin Metro Line 7, where a shield tunnel would be constructed near the existing pile groups of Shiyou Bridge. The whole shield tunnel is close to pile groups, and the minimum distance is only 0.8 m. Therefore, four kinds of protective schemes are proposed in this paper. It is vital to select an appropriate protective scheme to guarantee the safety during the tunnel construction. In this study, the main mechanical characteristic and physical parameters of site soil were obtained through laboratory tests. Besides, the three-dimensional finite element method was carried out to compare and analyze the effectiveness of the protective schemes in mitigating the effects of tunneling on adjacent pile groups. The results show that the deep-hole grouting scheme has better control effect on the lateral deformation and bending moment of piles, while the pile foundation underpinning scheme has better effectiveness on reducing the settlement of bridge structure and ground deformation. Finally, the deep-hole grouting reinforcement scheme will be adopted to ensure the shield passing through the pile groups smoothly. © 2020 Penglin Li et al.",,,,,,,,,,,,,,,,,,"Peck, R.B., Deep excavation and tunneling in soft ground, State of the art report (1969) Proceedings of 7th International Conference on Soil Mechanics and Foundation Engineering, pp. 225-290. , Mexico City, Mexico;

The systems for wireless energy transfer are not conveniently in the power levels required for some applications, as for the electric vehicle (EV), for instance, and there is a necessity to study different coil geometries to improve its efficiency and decrease its volume and weight. In this article, we presented a new hexagonal-geometry coil design placed in the secondary of a WPT, and the tests demonstrate that a Type-II system compliance requirements (SAE J2954) can be accomplished with greater efficiency and lighter weight compared to the circular coil. Finite element analyses accurately allow predicting the mutual inductance and achieving the optimal coil parameters and an experimental setup allows obtaining a rated power output of 7.7 kW operating at 85 kHz. The experimental testbed comprises a series-series resonance compensation circuit, a spiral coil used as primary, the proposed hexagonal pad for the secondary coil, and an ac-output, half-bridge inverter as a source, achieving a lighter, and efficient system in a realist scenario. © 2015 IEEE.","ANSYS Maxwell; hexagonal coil; high power; wireless charging","Charging (batteries); Energy transfer; Geometry; Inductance; ANSYS Maxwell; Compensation circuits; Experimental testbed; hexagonal coil; High power; Wireless charging; Wireless energy transfers; Wireless power transfer (WPT); Inductive power transmission",,,,,"Consejo Nacional de Ciencia y Tecnología, CONACYT: 4155","Manuscript received February 28, 2019; revised May 8, 2019 and July 8, 2019; accepted August 26, 2019.

The specimens consisted of two cast-in-place (CIP) reference columns and two precast columns for the study of socket and pocket connections, respectively. The precast columns were designed based on the actual application of precast urban viaducts in Shanghai, China. Therefore, this study investigated and verified the seismic performance of these connection approaches. Based on the test results of the hysteretic behavior and derived indexes, both columns with socket and pocket connections have shown equivalent seismic performances to their CIP references. The differences between precast and CIP columns were within 15% for all indexes, and the damage development and failure mechanism were also similar. Finite-element models were created with displacement analyser (DIANA) and calibrated with the test data. Bond-slip behavior with the built-in embedded reinforcement element, concrete cracking with tension softening, and material nonlinearity were considered. Under monotonic pushover analysis, the load-displacement curves were in good agreement with the backbone curves of the test results. © 2019 American Society of Civil Engineers.","Bridge column; Cyclic loading; Finite-element method; Pocket connection; Precast concrete; Seismic performance; Socket connection","Bridges; Cyclic loads; Finite element method; Hysteresis; Precast concrete; Seismic waves; Seismology; Bridge columns; Embedded reinforcements; Experimental and numerical studies; Load-displacement curve; Material non-linearity; Pocket connection; Seismic Performance; Socket connections; Failure (mechanical)",,,,,"National Natural Science Foundation of China, NSFC: 51778470","Financial support for this study was provided by the National Natural Science Foundation of China under Award No. 51778470.",,,,,,,,,,"Belleri, A., Riva, P., Seismic performance and retrofit of precast concrete grouted sleeve connections (2012) PCI J, 57 (1), pp. 97-109. , https://doi.org/10.15554/pcij.01012012.97.109; Brunesi, E., Nascimbene, R., Deyanova, M., Pagani, C., Zambelli, S., Numerical simulation of hollow steel profiles for lightweight concrete sandwich panels (2015) Comput.

The said bridge was designed based on optimization of an original 12-m bridge specimen. The bridge, so developed, is intended to be lightweight, structurally sound with modular feasibility, and representative of a construction that is less time consuming overall and fully exploits advantages offered by the use of inherent and complementary pultruded GFRP materials. Conceptual design and considerations of the large-scale structure were first described in detail. Subsequently, full-scale nondestructive tests were performed under on- and off-axis static loadings to evaluate the actual linearly elastic mechanical behavior of the prototype. Experimental results demonstrated that the bridge satisfactorily met the requirements of strength, overall bending stiffness, and torsional rigidity with regards to emergency-bridge applications. Being recognized as the most critical loading case for emergency bridges with major influence on load distribution among truss girders, the lateral live-loading distribution was assigned great importance during design of the unique bridge. Extrusion-type unidirectional GFRP profiles with high-longitudinal but low shear strengths are predominantly suitable for structures subjected to large axial forces, and are, therefore, appropriate for application in the proposed hybrid structural system. Favorable testing results demonstrated that the proposed improved version of the original conceptual design can appropriately be used as a truss girder for a new lightweight emergency bridge with a longer measured span. It is suggested that such a hybrid bridge, which demonstrates reasonably good linearly elastic behavior under service live loads, must also be designed in accordance with a stiffness criterion. Corresponding finite element and analytical analyses were performed and compared against experimental results whilst demonstrating good agreement. The elicited comparisons indicated that the established simplified analytical models and the finite element model (FEM) were both equally applicable for use in preliminary structural calculations and design of the improved bridge under states within its serviceability limit. Results reported herein are expected to make a valuable initial contribution, which in turn, could further lead to development of similar lightweight structural systems. © 2019 Elsevier Ltd","Bridge engineering; Dismountable truss; Emergency bridge; Hybrid structure; Mechanical response; Pultruded GFRP; Static nondestructive testing","Beams and girders; Bending strength; Conceptual design; Finite element method; Loads (forces); Nondestructive examination; Plate metal; Plates (structural components); Stiffness; Structural dynamics; Trusses; Bridge engineering; Emergency bridges; Hybrid structure; Mechanical response; Pultruded GFRP; Bridges; bridge; composite; design; finite element method; nondestructive testing; shear strength; stiffness",,,,,"National Natural Science Foundation of China, NSFC: 51708552; China Postdoctoral Science Foundation: 2017M623401; Natural Science Foundation of Jiangsu Province: BK20170752","This research was supported by the Natural Science Foundations of Jiangsu Province ( BK20170752 ), National Natural Science Foundation of China ( 51708552 ), Young Elite Scientist Sponsorship , and Postdoctoral Science Foundation Grant of China ( 2017M623401 ).

This paper presents amethodology and framework of such a cyber-physical system (CPS) that generates a bridge finite element model (FEM) integrated with vibration measurements from smartphone WSNs and centralized/distributed computational facilities, then assesses structural reliability based on updated FEMs. Structural vibration data obtained from smartphones are processed on a server to identify modal frequencies of an existing bridge. Withoutdesigndrawings andsupportivedocumentation but fieldmeasurements andobservations, FEMof the bridge is drafted with uncertainties in the structural mass, stiffness, and boundary conditions (BCs). Then, 2700 FEMs are autonomously generated, and the baseline FEMis updated byminimizing the error between the crowdsourcing-based modal identification results and the FEManalysis. Furthermore, using 151 strong ground motion records from databases, the bridge response time history simulations are conducted to obtain displacement demand distribution. Finally, based on reference performance criteria, structural reliability of the bridge is estimated. Integrating the cyber (FEM analysis) and the physical (the bridge structure and measured vibration characteristics) worlds, this crowdsourcing-based CPS can provide a powerful tool for supporting rapid, remote, autonomous, and objective infrastructure-related decision-making. This study presents a new example of the emerging fourth industrial revolution from structural engineering and SHMperspective. © 2019 by the authors.","Crowdsourcing; Cyber-physical systems; Finite element model updating; Modal identification; Structural health monitoring; Structural reliability estimation",,,,,,"Columbia University","The authors would like to acknowledge Demosthenes Long from Public Safety and Daniel Held from Facilities, Columbia University, for their support throughout on-campus pedestrian bridge tests.

The manufacturing process of cold-formed steel hollow sections can be divided into four main stages: (1) the coiling and uncoiling of a steel strip, (2) the transverse bending of the uncoiled strip into a circular shape, (3) the welding of the circular tube along the longitudinal strip edges, and (4) the shaping of the welded circular steel tube into a specific cross-sectional shape. In this paper, a finite element-based method is presented for predicting residual stresses and equivalent plastic strains in cold-formed steel hollow sections (including elliptical, square, and rectangular shapes of both normal grade steel and high strength steel). In this method, residual stresses and equivalent plastic strains due to the coiling, uncoiling and transverse bending operations are predicted analytically, and applied as the initial state for the subsequent finite element simulations of both welding and shaping operations. Predictions from this method show satisfying agreement with experimental measurements, which demonstrate the validity of the proposed method. This method can predict the distributions of residual stresses and equivalent plastic strains across the thickness and over the cross section, which are too complex to be measured completely in laboratory. The method provides a tool for investigating the effects of different material and forming parameters on the resulting cold work and structural behaviour. © 2019 Elsevier Ltd","Cold forming; Cold work; Finite element simulation; Hollow sections; Residual stresses; Shaping","Bending (forming); Box girder bridges; Cold working; Elasticity; Forecasting; Geometry; High strength steel; Plastic deformation; Residual stresses; Structural design; Studs (structural members); Tubular steel structures; Welding; Circular steel tubes; Cold forming; Cross-sectional shape; Equivalent plastic strain; Finite element simulations; Hollow section; Manufacturing process; Shaping; Finite element method; computer simulation; finite element method; plastic; residual stress; steel structure; strain",,,,,"Universidade de Macau, UM: MYRG073(Y1-L2)-FST13-QWM; Fundo para o Desenvolvimento das Ciências e da Tecnologia, FDCT: 129/2014/A3","The authors would like to thank the Fundo para o Desenvolvimento das Ciências e da Tecnologia (FDCT) of the Macao S.A.R.

Multiscale FE modeling couples multiple dimensions of elements in a single model. In this study, the selected existing multipoint constraint equations applied in planar coupling conditions are modified and refined for out-of-plane coupling conditions in a single three-dimensional FE model. Also, the optimum location for the interface points of different elements is determined to improve the model's accuracy and efficiency. The present case study, the Memorial Bridge in Portsmouth, NH, is a vertical lift bridge, which includes novel gusset-less connections. These connections have complex geometries and therefore require finer dimension elements to represent the structural behavior, while the remainder of the structure is modeled with coarser dimension elements. To achieve an accurate and efficient multiscale model of the Memorial Bridge, multiple global FE models are developed and the predicted structural responses are verified with respect to the field-collected structural responses of the bridge. © 2018 Computer-Aided Civil and Infrastructure Engineering",,"Bridges; Civil engineering structures; Multi point constraints; Multi-scale FE modeling; Multi-scale Modeling; Multiscale finite element; Service performance; Structural behaviors; Structural performance; Finite element method; bridge; equation; finite element method; numerical model; performance assessment; structural analysis; structural response; three-dimensional modeling; New Hampshire; Portsmouth [New Hampshire]; United States",,,,,"National Science Foundation, NSF; Directorate for Engineering, ENG: 1430260; New Hampshire Department of Transportation, New Hampshire DOT","This material is based upon work partially supported by the National Science Foundation under Grant No. 1430260, FHWA AID: DEMO Program and funding from the New Hampshire Department of Transportation Research Advisory Council.

A 1/70-scale bridge full model of a preliminary design super long-span cable-stayed with a central span of 1400 m was designed and tested on a shaking table array. The bridge full model included superstructure, pile groups and artificial soil placed in laminar shear boxes. Inelastic tower links used as sacrificial links scheme were installed in the top region between both tower shafts in the transverse direction. The dynamic characteristics and seismic responses of the bridge full model with and without the inelastic tower links were analyzed and compared under various uniform earthquake excitations in the transverse direction. The experimental results show that the addition of inelastic links to the tower improves the seismic performance of the cable-stayed bridge, and the tower seismic demands are reduced, including the displacement and strain responses. Especially, the inelastic tower links significantly decrease the strain responses in the tower top region. It is indicated that the inelastic tower links can tune the seismic response and mitigate the seismic damage of towers in high seismic regions. Moreover, an updated finite element (FE) model was conceived to replicate the experimental results using OpenSees, and the numerical simulations of the bridge full model were performed. Consequently, the numerical results are in good agreement with the experimental counterparts, thus validating the effectiveness and accuracy of the updated FE model. © 2018","Bridge full model; Cable-stayed bridges; Energy dissipation structural system; Inelastic tower links; Shaking table tests","Cables; Earthquakes; Energy dissipation; Numerical models; Piles; Seismic response; Towers; Dynamic characteristics; Earthquake excitation; Full model; Inelastic tower links; Numerical verification; Shaking table tests; Structural systems; Transverse seismic response; Cable stayed bridges; bridge; energy dissipation; experimental study; finite element method; numerical model; seismic response; shaking table test; structural response; transverse isotropy",,,,,"National Natural Science Foundation of China, NSFC: 51608282, 91515101-5; Ningbo University","This study was sponsored by the National Natural Science Foundation of China (Grant Numbers: 91515101-5 , 51608282 ).

The resistance of TMR changes with the magnetic flux density and a Wheatstone bridge circuit-based TMR can be used for current measurement. A toroid TMR current sensor is first proposed to measure the IGBT current, and the measured current is compared to references for protection. A prototype based on a 1200-V/200-A IGBT module is constructed to test the TMR sensor. A 120 A over-current can be detected in 604 ns. The measured current is also utilized to estimate the dc bus capacitance, experimental results show the maximum estimation error is 0.26%. Next, the TMR sensors are integrated into an IGBT module to expand the application scenario. The Calculation method and finite element method (FEM) are proposed to find optimal install locations of the TMR inside a 62-mm IGBT module. A differential TMR sensor circuit is employed to suppress the interference of the adjacent magnetic field. Experimental results based on a commercial IGBT with an integrated TMR sensor have been provided. The reaction time of the integrated TMR sensor is 530 ns and the maximum measurement error for the dc current is 0.85%. The detection and protection time for a 280-A short-circuit fault is 677 ns and 1.23 μs, respectively. © 1986-2012 IEEE.","Insulated gate bipolar transistor (IGBT); integration; over-current protection; short-circuit protection; tunnel magnetoresistance (TMR)","Bridge circuits; Magnetic circuits; Timing circuits; Tunnelling magnetoresistance; Application scenario; Current sensors; Estimation errors; Measured currents; Sensor circuit; Short-circuit fault; Tunnel magnetoresistance; Wheatstone bridge circuits; Insulated gate bipolar transistors (IGBT)",,,,,"National Natural Science Foundation of China, NSFC: 51607156; National Key Research and Development Program of China, NKRDPC: 2016YFB0100603","Manuscript received August 16, 2019; revised December 27, 2019 and February 24, 2020; accepted March 7, 2020.

This paper aims to fill this research gap. Firstly, four typical double-pier RC bridges are designed based on the Chinese seismic design specifications with consideration of different seismic hazard levels, and the corresponding refined finite element models are established by using LS-DYNA. Then, based on the validated material models and numerical algorithm, the numerical simulations of total 108 vehicle-pier collision scenarios are systemically performed, including the pick-up light truck, Ford 800 medium truck and tractor-trailer heavy truck with different tonnages of 3–30 t and collision velocities of 40–120 km/h. By assessing the pier's deformation and vehicular impact force, it derives that the bridge pier designed with the enhanced seismic capacity exhibits a lower damage level and survives the higher impact speed of heavy truck, as well as withstands the successive cargo impact. Besides, five potential failure modes of the seismic designed bridge pier under vehicular collisions are identified, i.e., local damage on pier, overall collapse of bridge structure, etc. Finally, a new explicit damage index is proposed by further considering the diameter and shear-span ratio of bridge pier, then the damage levels of the vehicular impacted pier and whole bridge structure are evaluated, and the corresponding damage evaluation diagrams are given. The current work could provide helpful reference in the evaluation and design of RC bridge pier regarding both the earthquake and vehicular collisions. © 2020 Elsevier Ltd","Bridge pier; Damage evaluation; Numerical simulation; Reinforced concrete; Seismic-vehicular impact","Bridge piers; Damage detection; Petroleum reservoir evaluation; Seismology; Service life; Specifications; Tractors (truck); Bridge structures; Collision scenarios; Collision velocity; Damage evaluation; Design specification; Numerical algorithms; Potential failure modes; Vehicular collisions; Seismic design; bridge; collision; damage mechanics; finite element method; numerical model; pier; reinforced concrete; seismic design; seismic hazard",,,,,"National Natural Science Foundation of China, NSFC: 51878507; Natural Science Foundation of Shaanxi Province: 2020JQ-619","The authors would like to acknowledge the financial support from National Natural Science Foundation of China (Grant No. 51878507 ) and Natural Science Basic Research Plan in Shaanxi Province of China (Grant No. 2020JQ-619 ).",,,,,,,,,,"Buth, C.E., Williams, W.F., Brackin, M.S., Lord, D., Geedipally, S.R., Abu-Odeh, A.Y., (2010), Collision loads on bridge piers: Phase 1.

In Iran's railway network, 3,700 bridges exist which all of these have been designed based on service load in the past (low-speed trains) and are still serving for trains at a maximum speed of 100 km/h. In the present study, two plain concrete arch bridges are investigated using finite element technique. For validation of numerical models, the crown deflection of the two bridges under static loading and the locomotive moving as well as the first three modes of the bridges were selected as a calibration criterion and compared with experimental results. In the second step, by categorizing the trains based on geometrical properties, 27 models of Asian and European high-speed trains and Euro-code suggestions have been detected to make sure all of the possible geometries have been counted. Afterward, 324 time-history dynamic analyses have been performed in order to assess the dynamic behavior of the bridges under the high-speed trains at speeds of 150, 200, 250, 300, 350 and 400 km/h. Finally, deflection and acceleration responses of the bridges for all 324 dynamic analyses at the main crown of the bridges have been extracted. The results indicate that the dynamic performance of these bridges under high-speed trains is affected by span length, vehicle motion speed, material stiffness, train coach distribution, and axles’ distances. The responses are increased by increasing the vehicle speed and the spacing of axles in bogies. In the case of acceleration and displacement responses, the effect of span length parameter appeared to be significant at every speed. The results achieved from the time-history analyses showed more sensitivity in the dynamic performance of the bridge with longer span length (2L20) to acceleration response and in the bridge with lower span length (5L06) to displacement response. © 2020 Institution of Structural Engineers","Axles distances;

In this paper, the combined finite and discrete element method (FDEM) benchmarked with an in-situ X-ray micro-computed tomography and diffraction experiment is applied to bridge this gap in the meso-scale concrete fracture behaviour. To this end, algorithms are developed for realistic-shaped particle, packing, and high-quality FEM mesh- generation based on Voronoi tessellation and spherical harmonics. Using comprehensive simulations of virtually generated meso-scale concrete samples, it is found that rough particulates in concrete can increase its stress bearing capacity by enhancing intra-aggregate fracture paths. Results show that, the hierarchical aggregate morphology expressed by the fractal dimension more directly determines the compressive strength. Among the accessible conventional shape indices, convexity is the most effective parameter to correlate the global concrete fracture stress. © 2020 Elsevier Ltd","Aggregate morphology; Computed tomography; FDEM; Meso-scale concrete; Spherical harmonic; Uniaxial compressing","Aggregates; Compressive strength; Computerized tomography; Concrete aggregates; Fractal dimension; Fracture; Fracture mechanics; Mesh generation; Morphology; Aggregate morphology; Cementitious materials; Effective parameters; Interfacial transition zone; Meso scale modelling; Particle morphologies; Three-phase composites; Voronoi tessellations; Concretes",,,,,"Australian Research Council, ARC: DP170104192","The authors would like to acknowledge the support from the Australian Research Council through its Discovery Project ( DP170104192 ) and Office of Global Engagement/Partnership Collaboration Awards through its USyd-NUS Partnership Collaboration Award for ‘Design and Optimisation of Advanced Composite Structures for Infrastructure Protection’.",,,,,,,,,,"Li, J., Zong, B.Y., Wang, Y.M., Zhuang, W.B., Experiment and modeling of mechanical properties on iron matrix composites reinforced by different types of ceramic particles (2010) Mater.

The hybrid girders have been utilised to provide a cost-effective solution because of the high material cost of S690. This investigation has been based on the finite element (FE) modelling by using ABAQUS program. Accordingly, material modelling of S690 has been verified by considering recent experimental tests in the literature. Then, the accuracy of the current FE models of the CWGs has additionally been checked successfully. Parametric study has been carried out on simply-supported girders, for bridge construction, considering mainly the influences of the hybrid ratio and corrugation dimensions on the behaviour of the CWGs built up from HSSs. A limiting slenderness ratio for the inelastic LTB of 2.3 has been found, where more slender girders would not benefit from using such HSS material. Additionally, the strengths of the girders have been compared with EC3 design model, which has been found to provide highly conservative predictions for the current girders. Consequently, a new design model has been suggested. This suggested bending strength is generally found to provide accurate predictions for the hybrid CWGs built up from flanges of S690 HSS; especially for girders failing inelastically. Finally, several comparisons have been provided that might aid the structural engineers in designing efficient hybrid cross-sections in the future. © 2020 Elsevier Ltd","Corrugated web; Design strength; Finite element; High-strength steel; Hybrid girder; Lateral-torsional buckling; S690","ABAQUS; Bending strength; Bridges; Buckling; Cost effectiveness; Finite element method; Flanges; High strength steel; Yield stress; Corrugated web; Design strength; Hybrid girders; Lateral-torsional buckling; S690; Beams and girders",,,,,"2019JDTD0017","This study is supported by Scientific Innovation Group for Youths of Sichuan Province (No. 2019JDTD0017 ), and such support is appreciated greatly by the authors.",,,,,,,,,,"Gkantou, M., Theofanous, M., Baniotopoulos, C., Plastic design of hot-finished high strength steel continuous beams (2018) Thin-Walled Struct., 133, pp. 85-95; Lai, B., Liew, J.Y.R., Hoang, A.L., Behavior of high strength concrete encased steel composite stub columns with C130 concrete and S690 steel (2019) Eng.

The bridge was made of prestressed ultra-high performance concrete box girders of four continuous spans of 30 m each. As the original design of such bridge was observed to be somewhat conservative, its cross-sectional dimensions, in the form of the box girder wall thicknesses were optimized in this research to lower the material cost in future bridge construction. Then, a full-scale simply supported ultra-high performance concrete box girder of 30 m span, incorporating the new box girder wall thicknesses, was fabricated and then tested under static loading to obtain research data to justify the revised design. The loading system was designed to examine the flexural behavior of the girder using two concentrated loads symmetrically located at the mid-span. Experimental results show that the optimized girder has a favorable ductile behavior and excellent flexural strength, which can meet the design requirements for serviceability and ultimate limit states. A finite element model of the tested girder was developed, using ABAQUS software, and then was verified using the experimental findings. A parametric study was then conducted to investigate the influence of key parameters on the structural response, namely, the reinforcement ratio, the number of the prestressing wires, and the web thickness. Recommendations on minimum and maximum compressive strength and tensile property of ultra-high performance concrete were proposed.

Nine cables on the same cable plane ruptured successively during the fire accident. As a result, the cantilever end of the girder dropped by 2.08 m, and the girder cracked severely. The cable tension, the displacements, and the damage state in the girder and pylon were measured to verify the nonlinear finite-element model. A comprehensive numerical study was then conducted to analyze the structural behavior of the bridge throughout the process of cable loss and subsequent restoration. The results from the field inspection and simulation showed that (1) the obvious change in cable tension and concrete cracking occurred in only the remaining cables and part of the girder within and around the cable loss area; (2) the loss of nine cables in the local area caused the combined action of torsion and biaxial bending in the girder, and resulted in dense distribution of diagonal cracks in the top slab and box girder webs; (3) after the accident, the maximum tensile stresses in the remaining cables and prestressed tendons reached 1,495 and 1,546 MPa, or 89.3% and 92.3% of the yield strength of steel strands, respectively, while the maximum principal compressive stress in the box girder reached 29.8 MPa, or 83.9% of the concrete compressive strength; and (4) the global structural performance of the damaged bridge recovered very well when the temporary cables that were added to replace the broken cables were jacked to the original design tension, indicating that the global behavior of the cable-stayed bridge was mostly controlled by the cables. © 2020 American Society of Civil Engineers.","Assessment; Cable loss; Cable-stayed bridge; Finite-element model; Fire accident; Static performance","Accidents; Box girder bridges; Bridge cables; Buffeting; Composite beams and girders; Compressive strength; Concretes; Disasters; Finite element method; Assessment; Concrete cable-stayed bridges; Concrete compressive strength; Finite element simulations; Fire accident; Long span cable stayed bridges; Non-linear finite element model; Static performance; Cable stayed bridges",,,,,"National Natural Science Foundation of China, NSFC: 51478177","The authors gratefully acknowledge the financial support provided by the National Natural Science Foundation of China (No. 51478177).

The traditional design process does not allow resolution of these challenges. The purpose of this project was to investigate the applicability of a Set-Based Parametric Design method to the structural design process of bridges. The focus was on the early design stage, in which the design team evaluates design alternatives against a chosen set of criteria. The main challenge in this stage of design is that the process should be cost- and time-effective while allowing comparison of the different alternatives and their evaluation in terms of the different design criteria. Certainly, structural design is often performed by a discussion between the different stakeholders involved in this process, i.e. the client, contractor, and engineering team. An evaluation of alternatives against criteria requires a more detailed design, which is contradictory to the early design stage when information is scarce. The selected approach was to develop a script that can generate information for decision-making, automate the structural design process, perform common routine design tasks, and control the numerical analysis. The method combined Set-Based Design, Parametric Design, Finite Element Analysis and Multi-Criteria Decision Analysis. Three existing bridges were selected to demonstrate the applicability of the developed method. The method was successfully applied and it was observed that it resulted in bridges that were more efficient in terms of material costs and carbon dioxide equivalent emissions compared with existing bridges. By delaying the decisions and developing the sets of alternatives, various alternatives can be assessed and evaluated, in the design stage, against different sustainability criteria. © 2019","Bridge design; Buildability; Finite element analysis; Multi-criteria decision analysis; Parametric design; Set-based design; Structural design; Sustainability","Carbon dioxide; Decision making; Finite element method; Structural analysis; Structural design; Sustainable development; Bridge design; Buildability; Multi-criteria decision analysis; Parametric design; Set-based designs; Bridges",,,,,,,,,,,,,,,,"Ward, A., Liker, J.K., Cristiano, J.J., Sobek, D.K., The second Toyota paradox: how delaying decisions can make better cars faster (1995) Sloan Manage.

The focus of this paper is on column applications. It addresses the understanding of the correlation between the mechanical properties of PFRP tubes and their material constituents. The burnout, tensile, compressive and shear tests were undertaken for square and circular PFRP tubes. Full scale compressive test was also conducted to compare the axial behaviour of pultruded FRP tubes. Moreover, a finite element analysis was carried out to simulate the compressive behaviour of full-scale specimens and to predict the axial behaviour of FRP columns of different length-to lateral dimension ratios. The results of compressive coupon tests are compared with those of full-scale tests which are used to check the accuracy of finite element simulation in terms of load-deflection curves, load capacity and failure mode. Results show that the strength and modulus depend on the fibre orientation and percentage of fibres in the axial direction. It further states the behaviour of full scale specimen is linear up to failure and the post peak behaviour of square tubes is affected by the continuity of non-axial fibre layers at corners.

The methodology uses sensor-clustering-based time series analysis of bridge acceleration responses to the motion of the train. The results are expressed in terms of damage features, and damage to the bridge is investigated by observing the magnitude of these damage features. The investigation demonstrates the damage features by comparing the fit ratios of locations of interest so that damage can be identified and located and the relative severity of the damage assessed. The damage cases considered are stiffness loss, moment capacity reduction, and change in boundary conditions. In this study, a finite element analysis of a railway bridge model is used to verify our methodology. Our findings show that the proposed damage detection framework is very promising for continuously assessing the condition of railway bridges and thus will facilitate early detection of potential structural damage. This will be valuable for infrastructure owners seeking to develop more economical and effective maintenance strategies. © 2019 John Wiley & Sons, Ltd.","damage detection; operational vibration data; sensor clustering; steel girder railway bridges; structural health monitoring; time series analysis","Harmonic analysis; Railroad bridges; Railroads; Steel beams and girders; Steel bridges; Structural analysis; Structural health monitoring; Time series analysis; Vibration analysis; Acceleration response; Bridge accelerations; Damage Identification; Detection framework; Maintenance strategies; Operational vibration; Railway bridges; Sensor clustering; Damage detection",,,,,"Networks of Centres of Excellence of Canada, NCE","This study is funded by IC-IMPACTS (the India-Canada Centre for Innovative Multidisciplinary Partnerships to Accelerate Community Transformation and Sustainability), established through the Networks of Centres of Excellence of Canada.",,,,,,,,,,"(2011) Bridge Preservation Guide.

In one earthquake region in China, the shear pins of FPB are required to be well to provide the enough shear force and stiffness under service loads (such as the vehicle forces being less than 170 kN in the longitudinal direction and 40 kN in the transverse direction) or small earthquake loads with a peak ground acceleration (PGA) being less than 0.1 g, however, are cut off to isolate seismic energy under large earthquake loads with a PGA being larger than 0.2 g. It is necessary to identify the appropriate strength of FPB shear pin to satisfy the above requirements. This paper selected the simply supported bridges on a single-line railway in the above earthquake region as the study object, which had a span length of 32 m and two height types of piers (8 m and 25 m). A prototype finite element model (FEM) and a scaled FEM were numerically analyzed, and a scaled experimental model was tested on shake table for each bridge. The results of them were compared with each other to validate the rationality of all models and to achieve the appropriate strength of FPB shear pin. The results show that the appropriate strengths of FPB shear pins are 540 kN in the longitudinal direction and 300 kN in the transverse direction for the bridge with the pier height of 8 m. Likewise, 350 kN and 270 kN are determined as the appropriate strengths of FPB shear pins for the bridge with the pier height of 25 m in the longitudinal and transverse directions, respectively. The numerical method of FEM is correct based on the experimental validation, and can be used to identify the appropriate strengths of FPB shear pins for other railway bridges. © 2019, Springer Nature B.V.","Friction pendulum bearing (FPB); Numerical analysis; Seismic isolation; Shaking table test; Shear pin; Simply supported railway bridge","Friction; Numerical analysis; Numerical methods; Pendulums; Piers; Railroad bridges; Railroads; Torque control; Experimental validations; Friction pendulum bearings; Longitudinal direction; Peak ground acceleration; Railway bridges; Seismic isolation; Shaking table tests; Simply supported bridge; Earthquakes; bridge; energy dissipation; friction; numerical method; peak acceleration; pier; railway transport; shaking table test",,,,,"2019JJ40386; National Natural Science Foundation of China, NSFC: 51778630, 51778635; Natural Science Foundation of Hunan Province: science2018-81; Department of Science and Technology of Sichuan Province, SPDST: 2019YFG0048","This research is jointly supported by the Science and Technology Project of Sichuan Province Under Grant No. 2019YFG0048, the National Natural Science Foundations of China Under Grant Nos. 51778635 and 51778630, the Natural Science Foundations of Hunan Province Under Grant No. 2019JJ40386, the Research Program on Displacement Limitation Technology of Half-through Railway Arch Bridge Under Grant No. science2018-81.

Usually used on the surface of old structures, devices for measuring such properties could also be adapted in order to be embedded inside the constitutive concrete of the linings of new tunnels or in new bridges, to contribute to structural health monitoring. This paper introduces a novel multi-electrode embedded sensor for monitoring the resistivity profile over depth in order to quantify concrete durability. The paper focuses on the design of the sensor as a printed circuit board (PCB), which brings several advantages, including geometric accuracy and mitigation of wiring issues, thus reducing invasiveness. The study also presents the numerical modeling of the sensor electrical response and its ability to assess an imposed resistivity profile, together with experimental validations using (i) saline solutions of known conductivity and (ii) concrete specimens subjected to drying. The results demonstrate the capability of the sensor to evaluate resistivity profiles in concrete with centimeter resolution. © 2019 Elsevier Ltd","(Multi-electrode) embedded sensor; Concrete structures; Electrical resistivity; Finite element modeling; Monitoring","Concrete construction; Concretes; Electric conductivity; Electrodes; Finite element method; Monitoring; Printed circuit boards; Printed circuit design; Concrete durability; Concrete specimens; Electrical response; Embedded sensors; Experimental validations; Printed circuit boards (PCB); Properties of concretes; Resistivity profile; Structural health monitoring",,,,,,,,,,,,,,,,"Bore, T., Wagner, N., Delepine Lesoille, S., Taillade, F., Six, G., Daout, F., Placko, D., Error analysis of clay-rock water content estimation with broadband high-frequency electromagnetic sensors—air gap effect (2016) Sensors, 16; Farhoud, R., Bertrand, J., Buschaert, S., Delepine-Lesoille, S., Hermand, G., Full scale in situ monitoring section test in the Andra's Underground Research Laboratory (2013) Proceedings of the 1st Conference on Technological Innovations in Nuclear Civil Engineering (TINCE), pp. 29-31. , Paris, France; Courtois, A., Clauzon, T., Taillade, F., Martin, G., (2015), Water Content Monitoring for Flamanville 3 EPR TM Prestressed Concrete Containment: an Application for TDR Techniques; Arsoy, S., Ozgur, M., Keskin, E., Yilmaz, C., Enhancing TDR based water content measurements by ANN in sandy soils (2013) Geoderma, 195, pp. 133-144; Dérobert, X., Iaquinta, J., Klysz, G., Balayssac, J.-P., Use of capacitive and GPR techniques for the non-destructive evaluation of cover concrete (2008) NDT & E Int., 41, pp. 44-52; Du Plooy, R., Lopes, S.P., Villain, G., Derobert, X., Development of a multi-ring resistivity cell and multi-electrode resistivity probe for investigation of cover concrete condition (2013) NDT & E Int., 54, pp. 27-36; Fares, M., Villain, G., Fargier, Y., Thiery, M., Derobert, X., Palma-Lopes, S., Estimation of water gradient and concrete durability indicators using capacitive and electrical probes (2015) NDT-CE 2015, International Symposium Non-Destructive Testing in Civil Engineering, p. 9; Sbartaï, Z.M., Laurens, S., Rhazi, J., Balayssac, J.P., Arliguie, G., Using radar direct wave for concrete condition assessment: correlation with electrical resistivity (2007) J.

Four modified push-out tests with different rubber ring thicknesses were conducted to investigate the shear behavior of RPBLs. The test results showed that specimens experienced four stages, including (i) damage of bond, (ii) shear fractures of concrete dowels, (iii) tension-shear yielding of perforated rebars, and (iv) hardening and fractures of perforated rebars. The rubber rings can significantly improve the slip capacity and drop the shear stiffness of perfobond connectors. Compared with ordinary perfobond connectors, the yield slips of specimens with 2 mm, 4 mm and 6 mm thick rubber rings increase by 304%, 509% and 745%. Further, three-dimensional nonlinear parametric FEA (finite element analysis) models of modified push-out tests were established and verified by the test results. The shear mechanism of each component and the effects of rubber ring thickness on shear behaviors were discussed. Finally, the shear yield load equations and shear capacity equations of PBL and RPBL were proposed based on the collected modified push-out test results. The calculated results agree well with the test results. © 2019 Elsevier Ltd","Composite bridges; Finite element analysis; Modified push-out test; Perfobond connectors; Rubber; Shear behavior","Composite bridges; Finite element method; Rubber; Analytical studies; Perfobond; Push-out tests; Shear behavior; Shear concentration; Shear fracture; Shear mechanisms; Shear stiffness; Shear flow; bridge; composite; computer simulation; experimental study; finite element method; numerical model; rubber; shear; stiffness",,,,,,,,,,,,,,,,"Liu, Y., Xin, H., He, J., Experimental and analytical study on fatigue behavior of composite truss joints (2013) J.

Debonding defects are one of the most dangerous types of damage in composite patches for repairing cracks and defects in aircraft structures. In the case of real debonding defect, a thin air layer is embedded between the aluminum and the epoxy resin adhesive. In general, an artificial debonding is simulated by inserting Teflon (Polytetrafluoroethylene) tapes within the joint. This paper proposes the application of polyurethane (PU) instead of polytetrafluoroethylene (PTFE) strip to simulate debonding in composite when the specimen is inspected by thermography technique. The effect of the simulation of debonding defect at the edge of composite patch using polyurethane, Teflon tapes, and air gaps under thermography inspection is studied. Finite element modeling (FEM) and experimental verification of debonding at the edge of composite patch show a different efficiency of thermography inspection due to different thermal properties of Teflon, polyurethane, and air gap (real debonding). Comparing the performance of thermography inspection of composite patch with debonding simulated by PU, PTFE and air reveal the importance of simulating defects with realistic industrial configurations. Finite element analysis and experimental results show that using the proposed polyurethane sheet instead of Teflon sheet can provide much more realistic simulation of debonding defect in composite patch subjected to thermography inspection. © 2019 Elsevier Ltd","Composite patch;

The displacement influence line (DIL) of the bridge under the live load tests is measured for a discrete number of target points. Three different remote sensing techniques including, laser scanning, terrestrial robotic total station and digital levelling are adopted for this purpose. It is demonstrated that DIL obtained by non-contact system is capable of identifying an emulated damage in an actual operating system. The contribution of the work is fourfold. First, a damage index based on the displacement profile of the bridge under the weigh-in-motion is extracted from the non-contact sensing system. Second, our study compares three different remote sensing techniques, namely, digital levelling, robotic total station and laser scanning and uses the measurements to validate the finite element model. Third, the effectiveness of the proposed method for structural damage identification is validated in a real-world large-scale operating structure. Finally, it is validated that strain-based influence line is highly likely to misidentify damage especially when the location of damage is not in the close proximity of the sensor; however, DIL is a better damage indicator even if damage occurs far from the measurement point. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.","Bridge health monitoring; cable-stayed bridge; displacement; finite element; influence line; measurement; natural frequency; non-contact sensing","Cable stayed bridges; Cables; Damage detection; Electric measuring bridges; Finite element method; Laser applications; Load testing; Measurement; Natural frequencies; Remote sensing; Robotics; Structural analysis; Bridge health monitoring; Condition assessments; displacement; Influence lines; Non-contact sensing; Remote sensing techniques; Robotic total station; Structural damage identification; Structural health monitoring",,,,,,,,,,,,,,,,"Alamdari, M.M., Rakotoarivelo, T., Khoa, N.L.D., A spectral-based clustering for structural health monitoring of the Sydney Harbour bridge (2017) Mechanical Systems and Signal Processing, 87, pp. 384-400; Alamdari, M.M., Kildashti, K., Samali, B., Goudarzi, H.V., Damage diagnosis in bridge structures using rotation influence line: Validation on a cable-stayed bridge (2019) Engineering Structures, 185, pp. 1-14; Anaissi, A., Makki Alamdari, M., Rakotoarivelo, T., Khoa, N., A tensor-based structural damage identification and severity assessment (2018) Sensors, 18 (2), p. 111; Annamdas, V.G.M., Bhalla, S., Soh, C.K., Applications of structural health monitoring technology in Asia (2017) Structural Health Monitoring: An International Journal, 16 (3), pp. 324-346; Asadollahi, P., Li, J., (2016), Statistical analysis of modal properties of a cable-stayed bridge through long-term structural health monitoring with wireless smart sensor networks.

Angle connectors and twin-perfobond rib (T-PBL)connectors are commonly used in long-span steel-concrete composite bridges. Considering the convenience of construction, a new type of shear connector, the channel connector, is proposed. Push-out tests on three groups of 12 shear connector specimens under monotonic and repeated loads were carried out, and the static and fatigue behavior of the three different shear connectors were compared and analyzed. The results show that the ultimate bearing capacity of channel connectors is the largest, while that for the angle connectors is the second largest and that for T-PBL connectors is the smallest. With the increase in cyclic loading times, the ratio of residual deformation to plastic deformation shows a significant upward trend. The deformation recovery ability of the specimens decreases gradually, and the stiffness deteriorates continuously. The stiffness degradation of channel connectors is the slowest, and the stiffness degradation of angle connectors and T-PBL connectors is faster. The energy dissipation of T-PBL connectors is the largest, while the energy dissipation of angle and channel connectors is the same. The channel connectors proposed in this paper can be used as good shear connectors in steel-concrete composite bridges because of their strength improvement and their certain energy dissipation capacity. In addition, the 3D non-linear finite element models based on the three kinds of shear connectors is established to simulate the whole loading process by using the general finite element software ABAQUS. The results of finite element analysis are in good agreement with the experimental results, which can be used as a powerful supplement to the experimental research. © 2019 Elsevier Ltd","Monotonic loading; Push-out test; Repeated loading; Shear connectors; Steel-concrete composite bridges","ABAQUS; Bearing capacity; Bearings (machine parts); Composite bridges; Concretes; Energy dissipation; Finite element method; Mechanical properties; Microalloyed steel; Stiffness; Monotonic loading; Push-out tests; Repeated loading; Shear connector; Steel-concrete composite bridges; Fatigue of materials",,,,,"201403; U.S. Department of Transportation, DOT: 2016023; National Natural Science Foundation of China, NSFC: 51478288","This study was supported by the National Natural Science Foundation of China (Grant 51478288), Zhejiang Department of Transportation Research Program (Grant 2016023)and Transport science and technology projects of Ningbo City (Grant 201403).

The XYθ micropositioning stage consisted of a working plate with a 12-inch hole in the center, three piezo actuators, and three displacement amplifiers based on the bridge-type flexure mechanism. Grey relation analysis and orthogonal array were incorporated with finite element analysis to find optimum design conditions. The grey relation grade with weight factors was used to simultaneously optimize three objective characteristics of the micropositioning stage: the maximum stroke, deflection of the working plate, and first natural frequency. The optimally-designed stage was fabricated by wire electrical discharge machining and tested to investigate its performance. The proposed stage showed the first natural frequency of 57 Hz and the maximum stroke of 122.84 μm, 108.46 μm, 0.685 mrad in the x-, y-, and θ-direction, respectively. The resolutions in corresponding directions were 11 nm, 10 nm, and 0.5 μrad. The performance of the stage was improved by optimum design process, and the experimental results were in good agreement with the predicted ones from the finite element analysis. © 2019 Elsevier Ltd","Flexure mechanism; Grey relation analysis; Micropositioning stage; Multiple objective functions; Optimum design","Design; Electric discharge machining; Electric discharges; Mechanisms; Natural frequencies; Rapid thermal annealing; Flexure mechanism; Grey relation analysis; Micro positioning; Multiple objective functions; Optimum designs; Finite element method",,,,,"Small and Medium Business Administration, SMBA; Korea Institute of Energy Technology Evaluation and Planning, KETEP: 20174010201310","This work was supported by the WC300 R&D program (S2341147) funded by the Small and Medium Business Administration (SMBA, Korea).

Based on previous extensive three-dimensional (3D) geometric surveys and mechanical characterization of both the soil constituting the riverbed and the masonry constituting the piers, a detailed 3D finite-element (FE) model was built. On-site ambient vibration tests have allowed dynamic characterization of the bridge. A preliminary sensitivity analysis on soil-structure interaction (SSI) parameters pointed out the key role of this boundary condition in the fitting of the mode shapes and their frequencies.

The repair comprises of welding headed shear studs to the non-corroded portion of the web plate and encasing them in ultra-high performance concrete (UHPC) to create an alternate bearing load path. The interaction between the headed studs and the UHPC panels is crucial in the force transfer. Therefore, a careful study is needed through high-fidelity finite element analysis to complement the experimental results. This paper presents the development of a model in Abaqus finite element software that enables capturing the behavior of studs embedded in UHPC. The model was validated using a series of experimental results from push-out tests with headed shear studs welded onto a thin web plate. Experimental results from push-out tests performed on stud diameters of 12, 16 and 19 mm and two levels of eccentric loadings were used to calibrate the modeling methodology. The model explicitly considers effects of material damage, contact between the studs and UHPC, and the precise geometry of the weld collar of studs. After validation, design parameters such as interaction of in-plane torsion and direct shear, and limits for web thickness-to-stud diameter ratio were studied to compliment the experimental data. The results are expected to inform engineers about the design of this novel repair method. In addition, this paper may enable future finite element studies on the performance of studs in UHPC. © 2019 Elsevier Ltd","Eccentric loading; Finite element model; Push-out; Shear studs; Ultra-high performance concrete","ABAQUS; Finite element method; Repair; Steel bridges; Steel corrosion; Studs (fasteners); Studs (structural members); Thermoelectricity; Welding; Abaqus finite element software; Eccentric loading; Finite-element study; Modeling methodology; Push-out; Shear studs; Steel bridge girders; Ultra high performance concretes; High performance concrete; concrete; finite element method; loading; numerical model",,,,,"Federal Highway Administration, FHWA; University of Connecticut, UCONN","This work was conducted as part of contract SPR-2295 (sponsored by the Connecticut Department of Transportation and Federal Highway Administration).

First, a wind model is presented with spectral representation method, the aerodynamic coefficients of bridge and vehicles before and after meeting are obtained through computational fluid dynamic method, and wind tunnel tests are conducted to verify the aerodynamic coefficients. Then, a vehicle dynamic model and a bridge dynamic model are established with the multi-body dynamic method and finite element method. Finally, a three-dimensional wind–vehicle–bridge coupled vibration model is established in this article using the multi-body dynamic software SIMPACK. The effects of average wind and fluctuating wind on the wind–vehicle–bridge system are studied. It is shown that the aerodynamic coefficients vary greatly under different combinations of vehicle–bridge system. The responses of the leeward vehicle change abruptly at the beginning and the end of the meeting of the two trains. And the mean wind speed has a great negative contribution to the acceleration of leeward vehicle. The lateral responses of suspended monorail vehicle are sensitive to the fluctuating wind. The roll angle of vehicle is presented for describing the running safety of the suspended monorail vehicles. © The Author(s) 2019.","aerodynamic coefficients; meeting of two trains; suspended monorail transit system; wind–vehicle–bridge coupling vibration","Aerodynamics; Computation theory; Computational fluid dynamics; Dynamic models; Vibration analysis; Wind; Wind tunnels; Aerodynamic coefficients; Computational fluid dynamic methods; Coupling vibration; meeting of two trains; Multi-body dynamic method; Spectral representation methods; Transit systems; Vibration characteristics; Automobile bodies",,,,,"Sichuan Province Science and Technology Support Program: 2017GZ0083; National Natural Science Foundation of China, NSFC: 51525804, 51778544; Sichuan Province Youth Science and Technology Innovation Team: 15CXT D0004","The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This study was financially supported by the Sichuan Science and Technology Program (no. 2017GZ0083), the National Natural Science Foundation of China (nos. 51778544 and 51525804), and the Sichuan Province Youth Science and Technology Innovation Team (no. 15CXT D0004).",,,,,,,,,,"Baker, C.J., The simulation of unsteady aerodynamic crosswind forces on trains (2010) Journal of Wind Engineering and Industrial Aerodynamics, 98 (2), pp. 88-99; Baker, C.J., Quinn, A., Sima, M., Full-scale measurement and analysis of train slipstreams and wakes.

The aim is to extend the field of filament winding from mainly 2D-shells and some exceptional cases of 3D rigid frames. This manufacturing process employs a coreless translation cross-winding method in order to continuously deposit a roving around deflection points in space. On this basis, a design methodology is being created and deductively verified by designing a beam for a three-point bending load case. The composite beam is designed on a macro level simulation approach to match the stiffness of a reference aluminum profile, which is commonly employed as structural component for robotic gripper systems in automotive assemblies. The performance of the beams is subsequently compared by three-point bending experiments. This demonstrates that the composite beam offers equivalent stiffness and strength properties with a weight-reduction potential of nearly 50% for bending loads. © The Author(s) 2018.","Carbon fibers; filament winding; finite element analysis; mechanical testing","Bridge decks; Carbon fibers; Composite beams and girders; Electric windings; Fibers; Finite element method; Grippers; Manufacture; Mechanical testing; Rigidity; Stiffness; Automotive assemblies; Design Methodology; Equivalent stiffness; Manufacturing process; Simulation approach; Structural component; Three point bending; Three-point-bending experiments; Filament winding",,,,,,"The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: Mercedes-Benz Cars, Daimler AG.",,,,,,,,,,"Minsch, N., Herrmann, F.H., Gereke, T., Analysis of filament winding processes and potential equipment technologies (2017) Proc CIRP, 66, pp. 125-130; Minsch, N., Mueller, M., Gereke, T., Novel fully-automated 3D coreless filament winding technology (2018) J Compos Mater, 52, pp. 3001-3013; Vasiliev, V.V., Razin, A.F., Anisogrid composite lattice structures for spacecraft and aircraft applications (2006) Compos Struct, 76, pp. 182-189; Vasiliev, V.V., Barynin, V.A., Razin, A.F., Anisogrid composite lattice structures – development and aerospace applications (2012) Compos Struct, 94, pp. 1117-1127; George, T., Deshpande, V.S., Wadley, H.N.G., Hybrid carbon fiber composite lattice truss structures (2014) Compos Part A: Appl Sci Manuf, 65, pp. 135-147; Li, W., Sun, F., Wang, P., A novel carbon fiber reinforced lattice truss sandwich cylinder: fabrication and experiments (2016) Compos Part A: Appl Sci Manuf, 81, pp. 313-322; Dong, L., Wadley, H., Shear response of carbon fiber composite octet-truss lattice structures (2016) Compos Part A: Appl Sci Manuf, 81, pp. 182-192; Heitz, T.W., (2013) The Physical-Mechanical Properties of Structural Components Made of Fiber Composite Materials in the Application of Steering Columns in Cars, , .

These undesirable features intensify with the use of Wide Bandgap (WBG) devices due to increased switching speed and lower on-resistance. In this paper, the parasitic inductance of the current commutation loop is modeled with Partial Element Equivalent Circuit (PEEC) method for SiC multichip module. Different from other studies, the mutual inductance between paralleled branches are thoroughly analyzed and included in the model. As shown in Finite Element Analysis (FEA) simulation and experiment measurement, the mutual inductance has significant influence on the accuracy of the model. A wire bonded package layout is then proposed for SiC multichip half bridge modules that could reduce parasitic inductance without increasing fabrication difficulty. The effectiveness of the developed structure is verified with 3D FEA simulation and experiment. © 2019 IEEE.","3D modeling; Electromagnetic interference; Finite Element Analysis; Multichip power module layout;

The results of the FEA indicated that V-ribs exhibited better fatigue performance than U-ribs on four typical fatigue details, and the rib-to-diaphragm welded connections in the two rib types were the most unfavorable aspects. A full-scale 5.6 million cycle fatigue test was then conducted to determine and compare rib fatigue resistance. The rib-to-diaphragm joints in the U-ribs were more prone to fatigue cracks than those in the V-ribs, and crack formation and extension did not result in significant deterioration of rigidity. The fatigue life of the U-ribs was 62.5 years, whereas that of the V-ribs was in excess of 169 years. The results indicated that the FAT90 (a stress range of 90 MPa at 2 × 107 cycles) fatigue class was the most suitable for estimating the fatigue resistance of rib-to-diaphragm welded connections in a railway OSD. © 2019 American Society of Civil Engineers.",,"Box girder bridges; Bridge decks; Cables; Cracks; Deterioration; Diaphragms; Fatigue testing; Railroad bridges; Railroads; Steel structures; Welding; Fatigue detail; Fatigue performance; Hot spot stress; Orthotropic steel decks; Railway bridges; Significant deteriorations; Steel box girders; Welded connections; Fatigue of materials",,,,,"National Basic Research Program of China (973 Program): 2017YFB0304805","This study was supported by the National Key Research and Development Program (2017YFB0304805).

For this purpose, an 875 m long bridge, located in Central Italy, founded on piles in eluvial-colluvial soil deposit was instrumented and ambient vibration tests together with geophysical investigations were performed. Experimental modal properties were evaluated by means of the operational modal analysis on accelerometric data and the role of soil-structure interaction in the interpretation of tests was detected by means of finite element models characterised by different accuracy in addressing the interaction problem. In the soil-structure interaction models the local site condition in correspondence of each bridge piers (resulting from geotechnical and geophysical investigations) were taken into account in the definition of the soil-foundation impedances. Comparison between the experimental results obtained from ambient noise measurements on the free-field and on the bridge deck permits the identification of both the predominant period of the site and the fundamental periods of the structure. In addition, comparisons between results obtained from the different numerical models with the measured dynamic response of the viaduct, in terms of fundamental frequencies and mode shapes, allow the identification of the contribution of different soil-structure interaction aspects such as the pile-soil-pile interaction, the radiation problem, the pile cap embedment as well as the variability of the soil stratigraphy along the longitudinal direction of the viaduct. © 2019 Elsevier Ltd","Dynamic identification; Finite element model; Operational Modal Analysis; Reinforced concrete viaduct; Site response; Soil-Structure Interaction","Dynamic response; Finite element method; Geophysics; Modal analysis; Numerical models; Reinforced concrete; Soil structure interactions; Soil testing; Soils; Stratigraphy; Structural geology; Vibration analysis; Ambient noise measurements; Ambient vibration test; Dynamic identification; Fundamental frequencies; Longitudinal direction; Operational modal analysis; Pile-soil-pile interaction; Site response; Piles; dynamic response; finite element method; pile response; reinforced concrete; site effect; soil-structure interaction; viaduct; vibration; Italy",,,,,,,,,,,,,,,,"Foti, D., Gattulli, V., Potenza, F., Output-only identification and model updating by dynamic testing in unfavorable conditions of a seismically damaged building (2014) Comput-Aided Civil Infrastruct Eng, 29, pp. 659-675; Omenzetter, P., Butt, F., Updating of an instrumented building model considering amplitude dependence of dynamic resonant properties extracted from seismic response records (2016) Struct Control Health Monit, 23, pp. 598-620; Ubertini, F., Comanducci, G., Cavalagli, N., Pisello, A.L., Materazzi, A.L., Cotana, F., Environmental effects on natural frequencies of the San Pietro bell tower in Perugia, Italy, and their removal for structural performance assessment (2017) Mech Syst Signal Process, 82, pp. 307-322; Behmanesh, I., Moaveni, B., Papadimitriou, C., Probabilistic damage identification of a designed 9-story building using modal data in the presence of modelling errors (2016) Eng Struct; Rainieri, C., Fabbrocino, G., Manfredi, G., Dolce, M., Robust output-only modal identification and monitoring of buildings in the presence of dynamic interactions for rapid post-earthquake emergency management (2012) Eng Struct, 34, pp. 436-446; Cabboi, A., Magalhães, F., Gentile, C., Cunha, A., Automated modal identification and tracking: application to an iron arch bridge (2017) Struct Control Health Monit, 24, p. e1854; Omenzetter, P., Beskhyroun, S., Shabbir, F., Chen, G.W., Chen, X., Wang, S., Zha, A., (2013), Forced and ambient vibration testing of full scale bridges.

This paper investigates the behavior of thin-walled steel columns with uniform square box sections (B) and newly proposed graded-thickness square box sections (GB) under constant axial and cyclic lateral loading. The analysis is carried out using a finite-element model (FEM) which takes into account the effect of both material and geometric nonlinearities. First, the accuracy of the employed FEM is verified based on the experimental results. Then, a GB column with size and volume of material equivalent to a B column is introduced. The proposed GB column is proved to have significant improvements in strength, ductility, and post-buckling behavior as compared to its counterpart B column. As a part of this research, a comprehensive parametric study is carried out to investigate the effects of main key parameters including: the width-to-thickness ratio parameter (R f ), the column slenderness ratio parameter (λ), the magnitude of axial load (P/P y ), and the number of loading cycles (N) on the strength and ductility of the B and GB columns. Finally, a series of proposed formulae for strength and ductility evaluation of the B and GB columns is given. © 2019 Elsevier Ltd","Buckling; Column slenderness ratio parameter; Cyclic loading; Ductility; Graded-thickness; Steel; Stiffened Square Box Section; Strength; Thin-walled; Width-to-thickness ratio parameter","Buckling; Composite beams and girders; Cyclic loads; Ductility; Steel; Thin walled structures; Column slenderness; Graded-thickness; Square box; Strength; Thin-walled; Width-to-thickness ratio; Loading; buckling; column; cyclic loading; ductility; steel structure; stiffness; strength",,,,,,,,,,,,,,,,"Jaiswal, K., Bausch, D., Rozelle, J., Holub, J., McGowan, S., (2017), Hazus® estimated annualized earthquake losses for the United States (No. FEMA P-366);; Mahin, S.A., Lessons from damage to steel buildings during the Northridge earthquake (1998) Eng Struct, 20, pp. 261-270; Miller, D.K., Lessons learned from the Northridge earthquake (1998) Eng Struct, 20, pp. 249-260; Nakashima, M., Inoue, K., Tada, M., Classification of damage to steel buildings observed in the 1995 Hyogoken-Nanbu earthquake (1998) Eng Struct, 20, pp. 271-281; Ucak, A., Tsopelas, P., Load path effects in circular steel columns under bidirectional lateral cyclic loading (2014) J Struct Eng, 141, pp. 1-11; Bedair, O., Novel design procedures for rectangular hollow steel sections subject to compression and major and minor axis bending (2015) Pract Period Struct Des Constr, 20, p. 04014051; Tao, Z., Han, L.H., Wang, Z.B., Experimental behaviour of stiffened concrete-filled thin-walled hollow steel structural (HSS) stub columns (2005) J Constr Steel Res, 61, pp. 962-983; Goto, Y., Mizuno, K., Prosenjit Kumar, G., Nonlinear finite element analysis for cyclic behavior of thin-walled stiffened rectangular steel columns with in-filled concrete (2012) J Struct Eng, 138, pp. 571-584; Guo, L., Yang, S., Jiao, H., Behavior of thin-walled circular hollow section tubes subjected to bending (2013) Thin-Walled Struct, 73, pp. 281-289; Yang, C., Zhao, H., Sun, Y., Zhao, S., Compressive stress-strain model of cold-formed circular hollow section stub columns considering local buckling (2017) Thin-Walled Struct, 120, pp. 495-505; Zhao, O., Rossi, B., Gardner, L., Young, B., Behaviour of structural stainless steel cross-sections under combined loading - Part I: Experimental study (2015) Eng Struct, 89, pp. 236-246; Mamaghani, I.H.P., Cyclic elastoplastic behavior of steel structures: theory and experiment (1996), Nagoya University; Mamaghani, I.H.P., Khavanin, M., Erdogan, E., Falken, L., Elastoplastic analysis and ductility evaluation of steel tubular columns subjected to cyclic loading (2008) Struct Congr 2008, pp. 1-12. , American Society of Civil Engineers Reston, VA; Bruneau, M., Performance of steel bridges during the 1995 Hyogoken-Nanbu (Kobe, Japan) earthquake—a North American perspective (1998) Eng Struct, 20, pp. 1063-1078; Gao, S., Usami, T., Ge, H., Ductility of steel short cylinders in compression and bending (1998) J Eng Mech, 124, pp. 176-183; Usami, T., Suzuki, M., Ge, H., Mamaghani, I.H.P., A proposal for check of ultimate earthquake resistance of partially concrete filled steel bridge piers (1995) J Struct Mech Earthq Eng, pp. 69-82; Li, H., Gao, X., Liu, Y., Luo, Y., Seismic performance of new-type box steel bridge piers with embedded energy-dissipating shell plates under tri-directional seismic coupling action (2017) Int J Steel Struct, 17, pp. 105-125; Mamaghani, I.H.P., Usami, T., Mizuno, E., Cyclic elastoplastic large displacement behaviour of steel compression members (1996) J Struct Eng, 42, pp. 135-145; Mamaghani, I.H.P., Usami, T., Mizuno, E., Inelastic large deflection analysis of structural steel members under cyclic loading (1996) Eng Struct, 18, pp. 659-668; Mamaghani, I.H.P., Usami, T., Mizuno, E., Hysteretic behavior of compact steel box beam-columns (1997) J Struct Eng JSCE, Japan, 43A, pp. 187-194; Ge, H., Gao, S., Usami, T., Stiffened steel box columns.

In the past, the lightning-induced damage was mainly described by thermal or thermoelectric approaches. However these approaches need to be supplemented by mechanical pressure/force concepts for describing the non-thermal mechanical damage caused by transient lightning current components, since thermal or thermoelectric simulations cannot describe and predict the global mechanical response and damage of CFRP structures. In this work, the elastic response and intralaminar damage of protected CFRP structures are computed using numerical methods. The finite volume (FV) approach is used to calculate the arc root expansion and the finite element (FE) approach is used to determine the effects of magnetic forces and of the shock waves due to supersonic lightning channel expansion. Furthermore, the near surface-explosions of the lightning protection layer are taken into account including an accurate arc root behaviour on the surface of the sample. This novel approach predicts the response of CFRP structures subjected to lightning strike loads without the need to fit the model to experimental data or recourse to experimentally determined parameters. The predictions agree well with experimental results and provide a new insight on the physics behind the mechanical behaviour of CFRP structures subjected to lightning strike. © 2018","Composite materials; Direct effects; Finite element; Finite volume; Lightning","Beams and girders; Bridge decks; Carbon fiber reinforced plastics; Carbon fibers; Composite materials; Fiber reinforced materials; Fiber reinforced plastics; Finite element method; Finite volume method; Lightning; Lightning protection; Numerical methods; Polymers; Reinforced plastics; Reinforcement; Shock waves; Carbon fibre reinforced polymer; Direct effects; Lightning currents; Mechanical behaviour; Mechanical pressure; Mechanical response; Near surface explosion; Simulation of lightnings; Transients",,,,,"NORTE-01-0145-FEDER-000022; Fundação para a Ciência e a Tecnologia, FCT: MITP-TB/PFM/0005/2013; Federación Española de Enfermedades Raras, FEDER; Bundesministerium der Verteidigung, BMVg: E/E210/AG008/GF057; European Regional Development Fund, ERDF; China National Tobacco Corporation, CNTC; Fundació Catalana de Trasplantament, FCT","The second author would like to thank the financial support provided by FCT – Fundação para a Ciência e a Tecnologia (Portugal) through National Funds in the scope of project MITP-TB/PFM/0005/2013 .","The work was partially performed within the project CNT Based Materials for EMI Shielding and LSP.

Despite its influence on bulk response of bone, the mechanical behavior of bone at ultrastructural level remains poorly understood. To fill this gap, in this study, a two-dimensional cohesive finite element model of bone at sub-lamellar level was proposed and analyzed under tensile and compressive loading conditions. In the model, ultrastructural bone was considered as a composite of mineralized collagen fibrils (MCFs) embedded in an extrafibrillar matrix (EFM) that is comprised of hydroxyapatite (HA) polycrystals bounded via thin organic interfaces of non-collagenous proteins (NCPs). The simulation results indicated that in compression, EFM dictated the pre-yield deformation of the model, then damage was initiated via relative sliding of HA polycrystals along the organic interfaces, and finally shear bands were formed followed by delamination between MCF and EFM and local buckling of MCF. In tension, EFM carried the most of load in pre-yield deformation, and then an array of opening-mode nano-cracks began to form within EFM after yielding, thus gradually transferring the load to MCF until failure, which acted as crack bridging filament. The failure modes, stress–strain curves, and in situ mineral strain of ultrastructural bone predicted by the model were in good agreement with the experimental observations reported in the literature, thus suggesting that this model can provide new insights into sub-microscale mechanical behavior of bone. © 2018, Springer-Verlag GmbH Germany, part of Springer Nature.","Bone mechanical response;

Because of their properties – such as high strength to weight ratios, ease of structure assembly, non-conductivity and chemical resistance – significant applications of the composite materials have been realised in the construction of footbridges in particular. In this paper, a numerical evaluation of the serviceability behaviour of two examples of composite material footbridges is presented. For the purpose of the study, it was assumed that the footbridges were made of the same composite material but they differ from each other with regard to structural geometry. The first stage of the study was the numerical estimation of the modal characteristics of the footbridges, i.e. their mode shapes and natural frequencies. The risk of the resonance phenomenon caused by pedestrian loading was then considered for both structures. In the next step of the calculations, the authors assessed the dynamic response of the footbridges to typical traffic loads; these types of load are transmitted to the structure through the ground and foundations. For numerical analysis, finite element (FE) models of the footbridges were prepared in the ABAQUS/Standard software program.

To derive the electromechanical coupled framework, Hamilton's variational principle is employed and the mechanical and electrical energy balance equations are considered in conjunction with suitable boundary conditions of the mechanical and electric fields. For the finite-element implementation, the output voltage is considered as an additional degree of freedom together with the displacement field. The developed finite-element model is then validated by comparison with the numerical results of the current finite-element model with closed-form solutions. The characteristics of the moving train load and corresponding train-induced vibration data measured on single- and double-span bridges are analyzed and the maximum vertical deflection is also evaluated for the safety assessment of the bridge. Lastly, the capability of the piezoelectric energy harvester as an energy-scavenging device on a railway bridge, the optimum location of the harvester, the optimum speed of the moving train, and the effect of resonance are discussed in terms of the generated output voltage and total energy. © 2018 American Society of Civil Engineers.","Energy; Finite-element method; Moving load; Piezoelectric energy harvesting; Railway bridge; Resonance; Validation","Degrees of freedom (mechanics); Energy harvesting; Piezoelectric devices; Piezoelectricity; Railroad bridges; Railroads; Resonance; Vibration analysis; Energy; Moving load; Piezoelectric energy harvesting; Railway bridges; Validation; Finite element method",,,,,,,,,,,,,,,,"(2012) User's Manual (Version 6.12), , ABAQUS.

Previous studies have indicated that welding the steel piles directly to a steel cap beam, regardless of weld configuration, does not avoid the undesirable brittle cracking failure mode in the welded region. Strengthening of the connection can a solution to shift the plastic hinge position from the connection to another point of the structure. Through static pushover and time-history analysis, the connection has been shown to adequately extend plastic hinging in the form of local buckling in the pipe pile wall, while avoiding unfavorable failure modes. The results of this study demonstrate that the use of composite connections can increase the shear capacity of a steel bridge; thus, improving its performance. Moreover, evaluation of the results shows that an increase in the length of the composite area will improve the overall ductility of the steel frame. Finally, a new composite connection has been proposed to improve the performance of the steel bridge; this will augment current efforts in strengthening bridges in earthquake-prone areas. © 2020 Elsevier Ltd","Cap beam; Composite connection; Cyclic performance; Pipe pile; Steel bridge; Time history analysis","Numerical methods; Piles; Plastic pipe; Steel bridges; Strengthening (metal); Welding; Composite connections; Composite steel concrete; Cyclic performance; Plastic hinging; Seismic Performance; Steel pipe pile; Time history analysis; Welded interface; Concretes; bridge; buckling; concrete; ductility; seismic response; shear; steel",,,,,"Fundação para a Ciência e a Tecnologia, FCT: POCI-01-0145-FEDER-031858","The first, second and third authors gratefully acknowledge to the Portuguese Foundation for Science and Technology (FCT) for its support under the framework of the research project POCI-01-0145-FEDER-031858 - INNOCFSCONC - Innovative hybrid structural solutions using cold-formed steel and lightweight concrete“ financed by FEDER funds through the Competitivity Factors Operational Programme-COMPETE and by national funds through FCT .",,,,,,,,,,"(2007), American Association of State Highway and Transportation Officials (AASHTO).

However, the bridge may be subjected to local scour within its service time. Therefore, it is necessary to assess the safety of the bridge under multiple hazards: local scour and vessel impact. In this effort, the nonlinear dynamic performance of a double-pylon cable-stayed bridge is investigated by a high-resolution finite-element (FE) method. First, to validate the accuracy of the FE model, a drop-hammer test conducted by previous researchers is simulated, and the numerical results show that the impact force, displacement, and failure modes match with those in the test for each case. Based on the validation, an FE model that constructs a complex colliding system for a double-pylon cable-stayed bridge and a ship is created to conduct nonlinear dynamic analysis. The impact forces, deformation of the pylon and pile foundation, and crush depths of the ship are calculated. The findings indicate that (1) local scour has a small effect on the rising step of ship impact force but affects its descending step; (2) the displacement at the impact point significantly increases with scour depth; (3) scour reduces the crush depth of the ship bow when the ship collides at lower collision velocities; (4) the ship impacts activate the vibration of the high-rise pylon, and the resulting damage severity in the pylon increases with scour depth under the same collision condition. The findings in this study can be used to guide the analysis and design of large-span bridges to resist local scour and ship impact. © 2020 Elsevier Ltd","Cable-stayed Bridge; Damage; High-rise Pylon; Local Scour; Ship Impact","Bridge piers; Cable stayed bridges; Cables; Piles; Ships; Vehicle performance; Bridge crossing; Collision velocity; Damage evaluation; Dynamic performance; High resolution; Multiple hazards; Numerical results; Safety evaluations; Scour; bridge; cable; damage mechanics; deformation; dynamic analysis; finite element method; force; performance assessment; pile; scour; vessel; vibration",,,,,"University of Missouri, MU; National Natural Science Foundation of China, NSFC: 51708484; Natural Science Foundation of Jiangsu Province: BK20170511; Natural Science Research of Jiangsu Higher Education Institutions of China: 17KJB580010","The authors thank the support from the National Natural Science Foundation of China through grant 51708484 , Natural Science Foundation of Jiangsu Province through grant BK20170511 , and Natural Science Foundation of the Higher Education Institutions of Jiangsu Province through grant 17KJB580010 .

The assessment of reinforced concrete bridges under seismic action needs the ability to model the effective non-linear response in order to identify the relevant failure modes of the structure. Existing RC bridges have been conceived according to old engineering practices and codes, lacking the implementation of capacity design principles, and therefore can exhibit premature shear failures with a reduction of available strength and ductility. In particular, recent studies have shown that the shear strength can decrease with the increase of flexural damage after the development of plastic hinges and, in some cases, this can cause unexpected shear failures in the plastic branch with a consequent reduction of ductility. The aim of the research is to implement those phenomena in a finite-element analysis. The proposed model consists of a flexure fiber element coupled with a shear and a rotational slip spring. The model has been implemented in the OpenSEES framework and calibrated against experimental data, showing a good ability to capture the overall response. © 2020 by the authors.","Bridge structures; Collapse modes; Finite element analysis; Flexure-shear failure; Reinforced concrete; Seismic assessment",,,,,,,"This research was funded by ReLUIS/DPC within the framework of the 2014-2018 and of the 2019-2021 Research Projects.

These factors significantly reduce the resistance of the rail track panel to shear across the axis of the path in the transition section. To predict the stability of a continuous welded rail on the transition sections, the following dependencies were calculated using the finite element method: the dependence of the critical temperature of the path on the number of sagging sleepers that have lost their grip to the ballast; the dependence of the critical temperature of the path on the percentage of weakening the pressure of the rail foot to the base; the dependence of the maximum transverse displacements to achieve a temperature close to the critical one, on the length of additional stiffening elements inside the track (additional rails). © 2020, Springer Nature Switzerland AG.","Transition sections; Transport; Welded rail","Ballast (railroad track); Rails; Temperature; Welding; Continuous welded rails; Critical temperatures; Longitudinal movements; Stiffening elements; Transition sections; Transport; Transverse displacements; Welded rails; Welded steel structures",,,,,,,,,,,,,,,,"Christopher, W., Research Results Digest 79-Design of Track Transition (2006) Transit Cooperative Research Program, 15, pp. 1-36. , TCRP Project D-7/Task, vol., pp; Coenraad, E., Modern Railway Track (2001) Mrt-Productions, pp. 157-170. , pp; Xiaoyan, L., Lijun, M., Dynamic response analyses of vehicle and track coupled system on track transition of conventional high speed railway (2004) J.

In the last decades, significant efforts have focused on linear FE models, including recent studies investigating applications with large models (i.e., models with many degrees-of-freedom) and/or models with a large number of parameters to be estimated (i.e., high-dimensional parameter space). Recently, increasing interests have been attracted to the calibration of nonlinear FE models, which has emerged as an attractive approach for damage diagnosis and prognosis, chiefly if Bayesian methods are employed to solve the inverse parameter estimation problem. A crucial step towards the application of damage identification methods based on nonlinear FE model updating in the real-world, is the validation for cases involving large and complex nonlinear FE models requiring the estimation of a high number of parameters. In this paper, the performance of the unscented Kalman filter (UKF) in updating these types of models is investigated and a batch-recursive variant to reduce the computational cost is proposed. In addition, the effects of considering heterogeneous response measurements are studied. Two application examples of large and complex FE models involving strong nonlinearities, including a two-dimensional steel frame building and a three-dimensional isolated bridge, with high number of unknown model parameters are examined. Significant computational time savings of the presented batch-recursive approach, without sacrificing the estimation performance, are found. This confirms the feasibility of using Bayesian techniques to calibrate large and complex hysteretic FE models of real-world systems with high-dimensional parameter space. The successful results obtained here show that the presented approach represents a novel and promising tool to update large nonlinear structural FE models involving a great number of parameters whose calibration might become prohibitive by means of conventional updating techniques. © 2019 Elsevier Ltd","Large and complex models; Model updating; Non-linear finite element model; Parameter estimation","Bayesian networks; Calibration; Damage detection; Degrees of freedom (mechanics); Inverse problems; Nonlinear analysis; Parameter estimation; Three dimensional computer graphics; Complex model; Damage Identification; Estimation performance; Finite-element model updating; Model updating; Non-linear finite element model; Parameter estimation problems; Unscented Kalman Filter; Finite element method; Bayesian analysis; calibration; damage mechanics; finite element method; nonlinearity; parameter estimation",,,,,"11160009; Comisión Nacional de Investigación Científica y Tecnológica, CONICYT; Universidad de Chile","R.

Analytical models of the bridge-type amplification mechanism and parallelogram mechanisms are developed by Castigliano's second theorem and a Beam constrained model. The amplification ratio, input stiffness, and output stiffness of the stage are further derived, based on the proposed model. In order to verify the theoretical analysis, the finite element method (FEM) is used for simulation and modal analysis, and the simulation results indicate that the errors of the amplification ratio, input stiffness, and output stiffness of the stage between the proposed model and the FEM results are 2.34%, 3.87%, and 2.66%, respectively. Modal analysis results show that the fundamental natural frequency is 44 Hz, and the maximum error between the theoretical model and the FEM is less than 4%, which further validates the proposed modeling method. Finally, the prototype is fabricated to test the amplification ratio, cross-coupling error, and workspace. The experimental results demonstrate that the stage has a relatively large workspace, of 346.1 μm × 357.2 μm, with corresponding amplification ratios of 5.39 in the X-axis and 5.51 in the Y-axis, while the cross-coupling error is less than 1.5%. © 2019 by the authors.","Beam constrained model; Bridge-type amplification mechanism; Castigliano's second theorem; Compliant mechanism; Micro-positioning stage","Chemical reactions; Compliant mechanisms; Errors; Mechanisms; Modal analysis; Stiffness; Amplification mechanism; Amplification ratio; Castigliano; Constrained models; Cross coupling errors; Micro positioning; Parallelogram mechanisms; Theoretical modeling; Bridges",,,,,"Natural Science Foundation of Shanghai: 19ZR1474000; National Natural Science Foundation of China, NSFC: 51605200, 51605271, 61973207","Acknowledgments: This work was supported by the National Natural Science Foundation of China under Grant 61973207, 51605271 and Grant 51605200, and the Natural Science Foundation of Shanghai 19ZR1474000.",,,,,,,,,,"Wang, F., Huo, Z., Liang, C., Shi, B., Tian, Y., Zhao, X., Zhang, D., A Novel Actuator-Internal Micro/Nano Positioning Stage with an Arch-Shape Bridge Type Amplifier (2018) IEEE Trans.

While the behavior of structural members made of CFS has been extensively studied at ambient conditions, the performance of these members under extreme events such as that associated with fire, is yet to be understood. In order to bridge this knowledge gap, this paper presents outcome of numerical studies aimed at understanding fire response of CFS beams. More specifically, this study explores the effect of temperature-induced shear-based instability on response of C-shaped CFS beams with slotted webs. For studying this phenomenon, a three-dimensional nonlinear numerical model is developed using the finite element (FE) simulation environment; ANSYS. The developed FE model is designed to incorporate temperature-dependent material properties as well as to account for unique geometric features and restraint conditions, as to accurately trace thermal and structural response of CFS beams. Once validated, the developed model was utilized to examine the effect of a number of factors namely; channel depth, web perforation pattern, as well as boundary conditions, on temperature-induced buckling susceptibility of CFS beams. The obtained results showed that these examined factors can significantly affect shear response of CFS channels with slotted webs at elevated temperatures. Findings observed from FE simulations were also shown to agree with that obtained from especially derived design expressions that give due consideration to geometric features and temperature-dependent material properties of slotted webs. This study concludes that in order to accurately capture the response of fire-exposed CFS beams, an accurate presentation of geometric and material features in such members is essential. © 2018 Elsevier Ltd","Buckling; Cold-formed steel (CFS); Finite element modeling; Fire resistance; Shear capacity; Slotted webs","Buckling; Fire resistance; Geometry; Shear flow; Steel beams and girders; Studs (structural members); Cold-formed steel; Cold-formed steel beams; Effect of temperature; Finite element simulations; Non-linear numerical model; Shear capacity; Slotted webs; Temperature-dependent material properties; Finite element method",,,,,,,,,,,,,,,,"Davies, J.M., Recent research advances in cold-formed steel structures (2000) J.

In particular, in finite element method (FEM) eddy current simulation, an extremely fine mesh is required to accurately simulate skin effects especially at high frequencies, and this could cause an extremely large total mesh for the whole problem, i.e., other surrounding structures and excitation sources like coils. Consequently, intensive computation requirements are needed. In this paper, an equivalent-effect phenomenon is found, which has revealed that alternative structures can produce the same effect on the sensor response, i.e., mutual impedance/inductance of coupled coils if a relationship (reciprocal relationship) between the electrical conductivity and the thickness of the structure is observed. By using this relationship, the mutual inductance/impedance can be calculated from the equivalent structures with much fewer mesh elements, which can significantly save the computation time. In Eddy current NDT, coils inductance/impedance is normally used as a critical parameter for various industrial applications, such as flaw detection, coating, and microstructure sensing. The theoretical derivation, measurements, and simulations have been presented to verify the feasibility of the proposed phenomenon. © 2013 IEEE.","Eddy current testing; electrical conductivity; non-destructive testing (NDT); skin effects; thickness measurement","Bridge decks; Electric conductivity; Inductance; Mesh generation; Skin effect; Thickness measurement; Alternative structure; Eddy current non destructive testing; Electrical conductivity; Equivalent effect; Excitation sources; Metallic structures; Non destructive testing; Theoretical derivations; Eddy current testing",,,,,"201803D421038; National Natural Science Foundation of China, NSFC: 61100029","This work was supported in part by the Shanxi Province Scientific International Cooperation Project of China under Grant 201803D421038.","This work was supported by the National Natural Science Foundation of China under Grant 61100029.",,,,,,,,,"Xu, D.-P., Lu, H.-W., Jiang, Y.-W., Kim, H.-K., Kwon, J.-H., Hwang, S.-M., Analysis of sound pressure level of a balanced armature receiver considering coupling effects (2017) IEEE Access, 5, pp. 8930-8939; Shubitidze, F., O'Neill, K., Haider, S.A., Sun, K., Paulsen, K.D., Application of the method of auxiliary sources to the wide-band electromagnetic induction problem (2002) IEEE Trans.

A two-mode field excitation scheme is presented, where the rotor of the WFSM was modified, and an additional harmonic winding is introduced with a rotating bridge rectifier. Mode I is the conventional direct dc supply field excitation using slip-rings and brushes, whereas mode II, is the brushless field excitation under an LOE fault, resulting in an unregulated field current. During mode II, a special coil switching is performed in the stator. Consequently, the stator winding creates an additional sub-harmonic component of the magneto-motive force (MMF) in the machine air gap along with the fundamental MMF component. The additional sub-harmonic MMF is induced in the rotor harmonic winding. A rotating diode bridge rectifier mounted on the rotor periphery rectifies the harmonic winding ac, and a stable dc was supplied to the rotor field winding. The decoupling between the additional rotor harmonic winding and stator winding is analyzed. The 2-D finite-element analysis (FEA) was performed to analyze the proposed idea. The FEA results were validated by experiments based on a 1-kW prototype. © 2013 IEEE.","Brushless excitation; coil switching; fault-tolerant operation; wound field synchronous machine","Bridge circuits; Fault tolerance; Harmonic analysis; Rectifying circuits; Stators; Synchronous machinery; Winding; Bridge rectifiers; Brushless excitation; Coil switching; Diode bridge rectifiers; Fault tolerant operations; Field-synchronous machines; Loss of excitation; Magnetomotive force; Rotors (windings)",,,,,"Ministry of Trade, Industry and Energy, MOTIE: 20174030201780; National Research Foundation of Korea, NRF; Korea Institute of Energy Technology Evaluation and Planning, KETEP","This work was supported in part by the Korea Institute of Energy Technology Evaluation and Planning (KETEP), in part by the Ministry of Trade, Industry and Energy (MOTIE), South Korea, under Grant 20174030201780, and in part by the National Research Foundation of Korea through the BK21PLUS Program within the Ministry of Education.","This work was supported by the Korea Institute of Energy Technology Evaluation and Planning (KETEP) and the Ministry of Trade, Industry & Energy(MOTIE) of the Republic of Korea (No. 20174030201780), and in part by the BK21PLUS Program through the National Research Foundation of Korea within the Ministry of Education.",,,,,,,,,"Chai, W., Zhao, W., Kwon, B.-I., Optimal design of wound field synchronous reluctance machines to improve torque by increasing the saliency ratio (2017) IEEE Trans.

A large number of ports and phases in the application necessarily requires a proportionally increased number of components, accessories, and connections. These additional parts induce significant losses and electromagnetic interference during high-frequency operations. Hence, fully manipulating the parasitic components, especially the leakage inductances of the transformer as the circuit element in the interconnected multi-port configuration, is a key to reduce the system's overall size and to improve its reliability. The proposed geometry and design method enables the full integration of a large number of otherwise bulky inductors to be included in the isolation transformers so that the latter function not only a step-up/down transformers but also as filter networks required for three-port DAB operations. The transformer is suitable for high-power and high step-up/down ratio DC-DC converters, which prefers a parallel combination of converters that share current, on the low-voltage side. The operating principles and steady-state analysis are presented with respect to power flow, and a three-winding shell-type isolation/filter transformer has been designed for a three-port three-phase Yyd DAB converter for solid state transformer applications. The finite element method simulations are used to validate the feasibility of the proposed approach. A prototype was fabricated and tested in an experimental setting. © 2019 IEEE.","Dual active bridge converter; solid state transformer; three-winding transformer","DC-DC converters; Delta wing aircraft; Electric inverters; Electric load flow; Electromagnetic pulse; Inductance; Winding; Dual active bridge converter; Finite element method simulation; High frequency operation; Isolation transformers; Medium voltage levels; Solid state transformer (SST); Steady-state analysis; Three-winding transformers; DC transformers",,,,,,"This work was supported by the Kyungnam University Foundation Grant, 2017.",,,,,,,,,,"Bhattacharya, S., Transforming the transformer (2017) IEEE Spectr., 54 (7), pp. 38-43. , Jul; Mainali, K., A transformerless intelligent power substation: A three-phase SST enabled by a 15-kV SiC IGBT (2015) IEEE Power Electron.

The framework assumes a time-varying auto-regressive (TAR) model for unknown loads and develops a strategy to simultaneously estimate those loads and parameters of the nonlinear model using an unscented Kalman filter (UKF). First, it is confirmed that a Kalman filter (KF) allows to estimate TAR parameters for a measured, earthquake, acceleration time-history. The KF-based framework is then coupled to an UKF to jointly identify unmeasured inputs and nonlinear finite element (FE) model parameters. The proposed approach systematically assimilates different structural response quantities to estimate TAR and FE model parameters and, as a result, updates the FE model and unknown external excitation estimates. The framework is validated using simulated experiments on a realistic three-dimensional nonlinear steel frame subjected to unknown seismic ground motion. It is demonstrated that assuming relatively low order TAR model for the unknown input leads to precise reconstruction and unbiased estimation of nonlinear model parameters that are most sensitive to measured system response. © 2020 Elsevier Ltd","Auto-regressive model; Finite element model; Input estimation; Kalman filter; Model updating","Concrete bridges; Kalman filters; Nonlinear analysis; Nonlinear systems; Parameter estimation; Sensor networks; Acceleration-time history; Auto regressive models; Input estimation; Model updating; Non-linear finite element model; Non-linear finite elements; Structural model parameters; Unscented Kalman Filter; Finite element method",,,,,"National Science Foundation, NSF: 1762034; Comisión Nacional de Investigación Científica y Tecnológica, CONICYT; Fondo Nacional de Desarrollo Científico y Tecnológico, FONDECYT: 11160009; Universidad de los Andes, Uniandes","The authors acknowledge the support from the Chilean National Commission for Scientific and Technological Research (CONICYT), FONDECYT project No. 11160009, and from the Universidad de los Andes – Chile through FAI initiatives.

In this paper, a comprehensive prediction model for void growth and fiber volume fraction is developed based on various time-dependent manufacturing characteristics in the filament winding process. This prediction model is basically decoupled into three sub-models: a diffusion-controlled void growth sub-model, a thermo-chemical sub-model and a resin flow sub-model for fiber volume fraction modeling. The relationships between manufacturing parameters and void size, fiber volume fraction are investigated by employing this new model. The results show that, in conventional models, the predicted size of voids was underestimated without considering the change of resin pressure and processing temperature. Strict control of the initial void size has limited benefits on reducing the final size of voids after winding process. However, the ambient humidity is critical to the control of the final void size in the composite products. Moreover, a higher winding tension will result in a smaller size of voids and a higher volume fraction of fibers, benefiting the improvement of product quality. © 2020 Elsevier Ltd","Curing; Filament winding; Finite element analysis (FEA); Void growth","Bridge decks; Fibers; Forecasting; Humidity control; Processing; Resins; Volume fraction; Comprehensive prediction; Conventional models; Diffusion controlled; Fiber volume fractions; Filament winding process; Manufacturing parameters; Mechanical performance; Processing temperature; Filament winding",,,,,"National Natural Science Foundation of China, NSFC: 11602030, 11802053, 11825202, U1837204","This work was supported by the National Natural Science Foundation of China (Nos.

Then the applicability of finite element model was validated against the experimental results. A subsequent parametric study was performed to investigate the effects of yield strength of steel, ratio of rib height to upper panel thickness, transverse reinforcement ratio and layout of ribs on the flexural behavior. Results show that the reduction of thickness of upper panel for waffle slab will significantly weaken its integrity and increase the risk of longitudinal splitting failure by comparing with reducing the number of ribs. The waffle slab with low ribs should be adopted as the bridge deck. The increase of transverse reinforcement ratio has little effect on improving the ultimate flexural capacity, while it is obvious for improving the ultimate deformation capacity. The minimum transverse reinforcement ratio of 0.5% is suggested. The contribution of ribs is small for flexural capacity but is large for ensuring ultimate deformation capacity. Finally, the calculation method of ultimate flexural capacity was proposed. The comparison of theoretical, experimental and numerical results revealed the good accuracy of predictions indicating that the actual behavior of SUCBWS was reasonably reflected by the calculation method. © 2020 Elsevier Ltd","Composite beam; Flexural working mechanism; Parametric analysis; UHPC; Ultimate flexural capacity; Waffle slab","Behavioral research; Composite beams and girders; Deformation; Finite element method; Numerical methods; Reinforcement; Deformation capacity; Flexural behavior; Numerical results; Splitting failure; Theoretical research; Three dimensional finite element model; Transverse reinforcement ratio; Ultimate flexural capacity; Steel research",,,,,"16YFZCSF00460; Tianjin Municipal Transportation Commission Science and Technology Development Plan Project: 2019B-21","This work presented here was supported by the Key Projects in the Science & Technology Pillar Program of Tianjin [grant number 16YFZCSF00460] and the Tianjin Transportation Science and Technology Development Plan Project [grant number 2019B-21].

Diagonal 647, Barcelona, 08028, Spain","Narrow-diameter implants (NDIs) traditionally have been associated to higher rates of failure in comparison with regular-diameter implants (RDIs) and wide-diameter implants (WDIs), since they generate a more unfavorable stress distribution in peri-implant bone. However, it is well known that the load sharing effect associated with prostheses supported by multiple implants (also called splinted prostheses) affords mechanical benefits. The present study involves finite element analysis (FEA) to determine whether the risks linked to NDIs could be mitigated by the mechanical advantages afforded by the splinting concept. For this purpose, a three-dimensional (3D) model of a real maxilla was reconstructed from computed tomography (CT) images, and different implants (NDIs, RDIs and WDIs) and prostheses were created using computer-aided design (CAD) tools. Biting forces were simulated on the prostheses corresponding to three different rehabilitation solutions: single-implant restoration, three-unit bridge and all-on-four treatment. Stress distribution around the implants was calculated, and overloading in bone was quantified within peri-implant volumes enclosed by cylinders with a diameter 0.1 mm greater than that of each implant. The mechanical benefits of the splinting concept were confirmed: the peri-implant overloaded volume around NDIs splinted by means of the three-unit bridge was significantly reduced in comparison with the nonsplinted condition and, most importantly, proved even smaller than that around nonsplinted implants with a larger diameter (RDIs). However, splinted NDIs supporting the all-on-four prosthesis led to the highest risk of overloading found in the study, due to the increase in compressive stress generated around the tilted implant when loading the cantilevered molar. © 2020 The Academy of Dental Materials","Compressive strength;

The Kriging model is used for the intelligent analysis and prediction of the actual stiffnesses of the existing bridges as well as for the high-accuracy prediction of their static load experimental results. In order to achieve the above objectives, a sensitivity coefficient is selected based on the sensitivity analysis of the whole bridge, and the Kriging model is established and optimized to forecast and modify sensitive parameters for the high-precision correction of the model. Relative to other machine learning algorithm models, the Kriging model has higher parameter sensitivity and reliability. To verify the correctness and feasibility of the above mentioned methods, a continuous rigid frame bridge is selected as an engineering test object, and ANSYS, a finite element software, is used for modeling and analysis. The research results show that the finite element model modification method based on the Kriging process can employ inexpensive and convenient bridge dynamic load tests to modify the actual parameters of the finite element model in the Kriging process of bridges; consequently, the test results of static load experiments can be more accurately predicted. The correction results obtained by the Kriging model are in good agreement with test results and exhibit high precision and reliability; moreover, the method is less costly and good safety, and has minimal influence on traffic. Moreover, in view of the potential for conducting a large number of bridge mechanical performance evaluations on all levels and the effective simulation and performance prediction of existing bridge project maintenance decisions, the proposed method affords a new train of thought. © 2020","Bridge engineering; Dynamic load test; Finite element model modification; Kriging process; Regression analysis; Static load forecasting","Bridges; Dynamic loads; Forecasting; Interpolation; Learning algorithms; Machine learning; Safety engineering; Sensitivity analysis; Software testing; Traffic congestion; Continuous rigid frame bridges; Finite element software; Intelligent analysis; Mechanical performance; Parameter sensitivities; Performance prediction; Sensitive parameter; Sensitivity coefficient; Finite element method; bridge; kriging; loading test; modeling; prediction; stiffness",,,,,"LGF19E080012; China Postdoctoral Science Foundation: 2016M600352","The writers gratefully acknowledge financial support provided by the Science Foundation of China Postdoctor (Grant No. 2016M600352).

This paper proposes a fatigue assessment protocol for these complex critical components of steel bridges, using the hotspot stress method. A computationally efficient finite element model of a large-scale bridge is created to provide the local structural response of complex components, under simulated dynamic traffic loads. A multi-scale model is implemented to accommodate higher dimension elements, which are recommended for fatigue assessment via hotspot stress method. The multi-scale model is created for the case study, the Memorial Bridge in Portsmouth, NH, which is a vertical lift steel truss bridge with a novel gusset-less curve-welded connection. A truck load test is used to validate the multi-scale model by comparing numerical results to the field collected data through the structural health monitoring system of the bridge. The result shows that the multi-scale model can determine the critical hotspot stresses, to study the fatigue performance of the bridge's critical components. © 2020 Elsevier Ltd","Complex structural components; Fatigue assessment; Gusset-less connection; Hotspot stress; Multi-scale model; Traffic simulation","Automobile testing; Finite element method; Load testing; Steel bridges; Structural health monitoring; Trusses; Welding; Complex structural components; Computationally efficient; Dynamic traffic loads; Fatigue assessments; Fatigue design codes; Fatigue performance; Multi-scale Modeling; Structural health monitoring systems; Fatigue of materials; bridge; dynamic analysis; fatigue; finite element method; loading; steel structure; stress analysis; structural analysis; structural response; three-dimensional modeling; New Hampshire; Portsmouth [New Hampshire]; United States",,,,,"National Science Foundation, NSF; Directorate for Engineering, ENG: 1430260","This material is based upon work partially supported by the National Science Foundation under Grant No. 1430260 , FHWA AID: DEMO Program and funding from the NHDOT Research Advisory Council .

Modern computational methods for modeling this behavior such as finite element analysis (FEA) are an ideal tool to fulfill this need. However, these analyses require many inputs that, due to the long timescales over which corrosion occurs, are often prohibitive to obtain through physical testing. In this research, a novel statistical approach using a neural network (NN) model has been constructed to approximate these inputs based on data in the literature from 107 concrete members. Then, outputs from the NN have been introduced into FEA material behavior models for the analysis of corrosion-damaged concrete beams. Load-deflection behavior resulting from such FEA shows good correlation when compared with available experimental data, confirming the accuracy of the NN. Thus, the NN is suggested as a means for obtaining inputs for FEA of corrosion-damaged concrete members. © 2020 Institution of Structural Engineers","Combined model; Computational intelligence; Finite element method; Neural network; Novel statistical approach; Prediction",,,,,,"Prince Sattam bin Abdulaziz University, PSAU","The authors gratefully acknowledge the technical support received from the Department of Civil Engineering, Faculty of Engineering, Prince Sattam Bin Abdulaziz University.",,,,,,,,,,"Howard, D., Mark, B., Martin, H., Neural network toolbox for use with MATLAB (1998) User's Guide Version, p. 3; Yu, L., Structural performance of RC beams damaged by natural corrosion under sustained loading in a chloride environment (2015) Eng Struct, 96, pp. 30-40; El Maaddawy, T., Soudki, K., Topper, T., Long-term performance of corrosion-damaged reinforced concrete beams (2005) ACI Struct J, 102 (5), p. 649; Zhu, W., Effect of corrosion of reinforcement on the mechanical behaviour of highly corroded RC beams (2013) Eng Struct, 56, pp. 544-554; Wang, X.-H., Effect of bond and corrosion within partial length on shear behaviour and load capacity of RC beam (2011) Constr Build Mater, 25 (4), pp. 1812-1823; Almusallam, A.A., Effect of degree of corrosion on the properties of reinforcing steel bars (2001) Constr Build Mater, 15 (8), pp. 361-368; Zhu, W., François, R., Coronelli, D., (2012), Effect of corrosion of reinforcement on the coupled shear and bending behaviour of reinforced concrete beam.

A framework for fatigue damage prognosis of OSD in long-span cable-stayed bridges is thus presented in this paper. The main features of the framework include hourly traffic loading simulation and prediction, multi-scale finite element bridge model, coupled vehicle-bridge system, mesh-insensitive equivalent stress responses at a DTR joint, response surface models for equivalent stress responses, OSD and pavement interaction, asphalt pavement temperature effect, fatigue test-generated S-N curve, and fatigue damage prognosis. To evaluate the feasibility of the proposed framework and to manifest the effects of pavement roughness, asphalt temperature, and vehicle transverse locations on fatigue damage accumulation, a real long span cable-stayed bridge is investigated as a case study. The results indicate that the developed framework is applicable and that the fatigue damage of a DTR joint is underestimated if the time-variant temperature of asphalt pavement and road surface condition are not considered but the fatigue damage is overestimated without consideration of variable transverse locations of vehicles. © 2020 Elsevier Ltd","Cable-stayed bridge; Fatigue damage prognosis; Multi-scale model; Orthotropic steel deck; Pavement and deck interaction; Stochastic traffic flow; Stress response surface; Vehicle-bridge coupled system","Asphalt mixtures; Asphalt pavements; Bridge decks; Buffeting; Cables; Fatigue damage; Fatigue testing; Road vehicles; Stochastic models; Stochastic systems; Stress analysis; Surface properties; Thermal fatigue; Traffic surveys; Coupled systems; Fatigue damage prognosis; Multi-scale Modeling; Orthotropic steel decks; Stochastic traffic flows; Stress response; Cable stayed bridges; bridge; damage mechanics; dynamic response; fatigue; finite element method; numerical model; pavement; road traffic; steel structure; vehicle component",,,,,"Research Grants Council, University Grants Committee, RGC, UGC: RGC 15218414; Hong Kong Polytechnic University, PolyU: PolyU 4-ZZGD","The authors are grateful for the financial supports by the Hong Kong Research Grants Council through its competitive grant (RGC 15218414) and The Hong Kong Polytechnic University through a special grant (PolyU 4-ZZGD).

The formulation presented in this paper is suitable for describing shape memory behaviors such as fixed-strain, stress-recovery and stress-free, strain-recovery, as well as for multiple shape memory effect in uniaxial and combined extension-torsion problems. To verify the results, a comparison has been carried out among the proposed formulation results and those of experiments and 3D finite element analysis outcomes. Compared to the finite element analysis, semi-analytical solutions are interesting due to their very low computational cost. It was observed that the solution time for the proposed method is much lower than the computational time needed for the FE analyses (around 1%). Therefore, the presented solution can be employed as an efficient tool for examining the effects of changing any of the material or geometrical parameters on smart structures consisting of SMP components under torsion-extension for their design and optimization, which involves a large number of simulations. Additionally, the proposed solution is suitable for calibrating material parameters in both uni-axial and 3D benchmark problem of torsion-extension. © 2020 IOP Publishing Ltd.",,"Concrete bridges; Deformation; Finite element method; Geometry; Polymers; Recovery; Shape-memory polymer; Torsional stress; Viscoelasticity; 3D-finite element analysis; Bench-mark problems; Computational costs; Design and optimization; Semi-analytical solution; Shape memory behavior; Thermo-mechanical behaviors; Thermo-viscoelastic; Shape optimization",,,,,,,,,,,,,,,,"Baghani, M., Naghdabadi, R., Arghavani, J., Sohrabpour, S., A thermodynamically-consistent 3D constitutive model for shape memory polymers (2012) Int.

The finite element model (FEM) adopted in this paper considers cracking and spalling of cover concrete, buckling and low-cycle fatigue of longitudinal steel bars, as well as bond-slip (strain penetration) between longitudinal bars and concrete. A fiber-based damage model based on material strains of concrete and reinforcing steel was used to predict the evolution and progress of damage in RC bridge piers. Two sets of test data of RC specimens were used to verify the applicability of the FEM and the damage model. A parametric analysis was conducted to derive suitable modeling parameters for reinforcing steel to accurately simulate the mechanical properties of HSSB with/without distinct yield plateau, and the resulting seismic performance of RC piers. The FEM used herein could reflect the effects of buckling and low-cycle fatigue of longitudinal steel bars as well as bond slip (strain penetration) on cyclic response of RC piers.

A constant electric field distribution through the thickness of plate is considered. An eight-node quadrilateral plate element with five mechanical degrees of freedom (DOFs) and one electric degree of freedom is developed for finite element analysis. Four typical forms of CNT distributions are included in the model, namely uniform, V-shaped, O-shaped, and X-shaped distributions. The nonlinear model considers fully geometrically nonlinear strain-displacement relations and large rotations of the shell direction of plate. Using the Hamilton's principle, a nonlinear dynamic model including dynamic and sensory equations is obtained. The proposed nonlinear model is validated by a frequency analysis of a simply supported P-CNT-FG composite plate. Furthermore, the effects of various parameters on the static and dynamic behavior are investigated, e.g. CNT-reinforcement orientation, CNT distribution, the number of laminate layers and volume fraction. © 2019 Elsevier Ltd","CNT functionally graded;

As such, it possesses characteristics that may be highly beneficial for protective structural applications. In this research, several structural characteristics from nacre's brick and mortar-like microstructure are mimicked with the goal of enhancing the stiffness and fracture toughness of a monolithic ceramic panel under blast loading. These features include the mineral bridges connecting the adjacent brick-like tablets for enhancing the stiffness of the panel, the multi-layered structure for enhancing its toughness via crack bridging mechanisms and the growth bands between the nacreous tablet layers for deflecting cracks. The results from the numerical simulations showed that the nacre-like panel possesses superior energy dissipation over the monolithic ceramic panel, which thereby reduces the reaction forces transmitted to the supports and mitigates catastrophic failure. This has positive implications in terms of the capability of fine-tuning the structural characteristics of an armor system for defeating impulsive loads, by employing the principles adopted in the microstructure of a natural armor system. © 2019 Elsevier Ltd","Bio-mimetic; Blast; Finite element; Impulsive; Nacre; Numerical; Structure","Armor; Biomimetics; Blasting; Brick; Cracks; Energy dissipation; Finite element method; Gems; Microstructure; Stiffness; Structure (composition); Catastrophic failures; Crack bridging mechanism; Impulsive; Multi-layered structure; Nacre; Numerical; Structural applications; Structural characteristics; Fracture toughness",,,,,"Australian Research Council, ARC: DP170100851","This research was funded through the Australian Research Council , Discovery Project, DP170100851 .",,,,,,,,,,"Wang, R.Z., Wen, H.B., Cui, F.Z., Zhang, H.B., Li, H.D., Observations of damage morphologies in nacre during deformation and fracture (1995) J Mater Sci, 30, pp. 2299-2304; Wang, R.Z., Suo, Z., Evans, A.G., Yao, N., Aksay, I.A., Deformation mechanisms in nacre (2001) J Mater Res, 16 (9), pp. 2485-2493; Tang, H., Barthelat, F., Espinosa, H.D., An elasto-viscoplastic interface model for investigating the constitutive behavior of nacre (2007) J Mech Phys Solids, 55, pp. 1410-1438; Jackson, A.P., Vincent, J.F.V., Comparison of nacre with other ceramic composites (1990) J Mater Sci, 25, pp. 3173-3178; Currey, J.D., Mechanical properties of mother of pearl in tension (1977), pp. 443-463. , Proceedings of the Royal Society of London Series B-Biological Sciences 196(1125); Ekiz, O.O., Dericioglu, A.F., Kakisawa, H., An efficient hybrid conventional method to fabricate nacre-like bulk nano-laminar composites (2009) Mater Sci Eng, C, 29, pp. 2050-2054; Currey, J.D., Taylor, J.D., The mechanical behaviour of some molluscan hard tissues (1974) J Zool, 173, pp. 395-406; Ortiz, C., Boyce, M.C., Bioinspired structural materials (2008) Mater Sci, 319 (5866), pp. 1053-1054; Kakisawa, H., Sumitomo, T., The toughening mechanism of nacre and structural materials inspired by nacre (2011) Sci.

The finite element method is used for the three-dimensional analysis of the structure under dead and live loads, time-dependent effects and geometrical nonlinearities are considered. The dynamic analysis is solved by the modal/spectral approach. The design problem is posed as a multi-criteria optimization. The design variables are the cable forces and the cross-sectional dimensions of cables, deck and towers. Design objectives of minimum cost, deflections, natural frequencies and stresses considering both, serviceability and ultimate limit states are considered. Given that a gradient-based algorithm is applied for the optimization the discrete direct method is used for sensitivity analysis. An entropy-based algorithm finds economically and structurally efficient solutions by rearranging the stiffness and mass distribution to enhance the structural response.

Simulations were conducted using two-dimensional (2D) PLAXIS 2016 Finite Element (FE) program. The hardening soil model proposed by Schanz et al. (1999) was used to simulate the behavior of the backfill material; the interface between the backfill materials and the reinforcement was simulated using the Mohr-Coulomb frictional model, and the reinforcement and facing block were simulated using the linear elastic model. The numerical model was first verified using results of a field case study conducted at the GRS-IBS of Maree Michel Bridge, Louisiana. A parametric study was then carried out to investigate the effects of abutment height, span length, reinforcement spacing, and reinforcement stiffness on the performance of the GRS-IBS. The results of the FE analyses indicate that the abutment height and span length have significant impact on the maximum strain distribution along the geosynthetic, and the lateral facing displacement. It was noted that the reinforcement stiffness has a significant impact on the GRS-IBS behavior up to a certain point, beyond which the effect tends to decrease contradictory to the reinforcement spacing that has a consistent relationship between the GRS-IBS behavior and the reinforcement spacing. The results also indicate that the reinforcement spacing has greater influence on the lateral facing displacement than the reinforcement stiffness for the same reinforcement strength to spacing ratio (Tf/Sv), mainly due to the composite behavior resulting from closely reinforced soil. © 2019","Bridge abutment; Finite element analysis; Geosynthetic Reinforced Soil (GRS); Geosynthetics; Integrated Bridge System (IBS); Parametric study","bridge; finite element method; geosynthetics; loading; numerical model; parameterization; soil reinforcement; strain; Louisiana; United States",,,,,,,,,,,,,,,,"Abu-Farsakh, M., Saghebfar, M., Ardah, A., Chen, Q., A case study on evaluating the performance of a Geosynthetic Reinforced Soil Integrated Bridge System (GRS-IBS) (2017) Geotechnical frontiers, pp. 12-22; Abu-Hejleh, N., Wang, T., Zornberg, J.G., Performance of geosynthetic-reinforced walls supporting bridge and approaching roadway structures (2000) Advances in transportation and geoenvironmental systems using geosynthetics, pp. 218-243; Adams, M., Performance of a prestrained geosynthetic reinforced soil bridge pier (1997) Mech Stab backfill, pp. 35-53; Adams, M., Nicks, J., Stabile, T., Wu, J., Schlatter, W., Hartmann, J., Geosynthetic reinforced soil integrated bridge system, interim implementation guide (No. FHWA-HRT-11-026) (2011); Adams, M.T., Ketchart, K., Wu, J.T., Mini pier experiments: geosynthetic reinforcement spacing and strength as related to performance (2007) Geosynthetics in reinforcement and hydraulic applications, pp. 1-9; Adams, M.T., Lillis, C.P., Wu, J.T.H., Ketchart, K., Vegas mini pier experiment and postulate of zero volume change (2002) Proceedings, seventh international conference on geosynthetics, pp. 389-394; Adib, M., Mitchell, J.K., Christopher, B., Finite element modeling of reinforced soil walls and embankments (1990) Design and performance of earth retaining structures, pp. 409-423. , ASCE; Ardah, A., Abu-Farsakh, M., Voyiadjis, G., Numerical evaluation of the performance of a Geosynthetic Reinforced Soil-Integrated Bridge System (GRS-IBS) under different loading conditions (2017) Geotextiles and geomembranes; Brinkgreve, R.B.J., (2002) Plaxis: finite element code for soil and rock analyses: 2D-version 8: [user's Guide], , Balkema; Chen, Q., Abu-Farsakh, M., Sharma, R., Experimental and analytical studies of reinforced crushed limestone (2009) Geotext Geomembr, 27 (5), pp. 357-367; Christopher, B.R., Gill, S.A., Giroud, J.P., Juran, I., Mitchell, J.K., Schlosser, F., Reinforced soil structures Volume I.

The proposed micro gripper combines traditional machining techniques with MEMS technologies to produce a modular mechanism consisting of a sturdy, compliant aluminium base and replaceable end-effectors. This creates an easily-customisable solution for micro manipulation with an array of different micro tips for different applications. We have provided the kinematic analysis for the gripper to predict the output and have also optimised design parameters based on FEA (finite element analysis) simulation and the effects of altering flexure beam lengths. The gripper is operated by a piezo actuator capable of 18 μm displacement at 150 V of applied DC voltage. This is then amplified by a factor of 8.1 to a maximum tip displacement of 154 μm. This is achieved by incorporating bridge and lever amplifying techniques into the design. An initial experimental analysis of the micro gripper is provided to investigate the performance of the micro gripper and to gauge the accuracy of the theory and simulation through comparison with experimental results. © 2019 by the authors.","Cell manipulation; Compliant micro gripper; Micro manipulation; Micro mechanisms; Piezo actuator","Actuators; Micromanipulators; Molecular biology; Cell manipulation; Micro gripper; Micro manipulation; Micro mechanisms; Piezo actuator; Grippers",,,,,"Royal Society Te Apārangi: MAU1714","Funding: Supported by the Marsden Fund Council from Government funding, managed by Royal Society Te Aparangi (MAU1714).",,,,,,,,,,"Drexler, K.E., Peterson, C., Pergamit, G., (1991) Unbounding the Future, p. 294. , William Morrow: New York, NY, USA; Kummer, M.P., Abbott, J.J., Kratochvil, B.E., Borer, R., Sengul, A., Nelson, B.J., OctoMag: An electromagnetic system for 5-DOF wireless micromanipulation (2010) IEEE Trans.

The explored sandwich structure was made of mineral-glass fibre reinforced polymer (GFRP) skins and a GFRP truss core, fabricated by means of a novel manufacturing method. The compressive and shear specific strengths of the panels were assessed and compared with a few common lightweight structures to verify that the manufactured truss core had comparable values. Three-point bending tests indicated that the polyurethane foam used (required for the manufacturing process) had negligible mechanical contribution. Full-scale panels were tested under a distributed load. The tests were simulated using the three-dimensional finite element method to predict the pressure at which mineral cracks appeared in order to avoid their occurrence in the design phase. The simulation results exhibited good agreement with experimental data, and the model was validated in terms of deflection and strain responses. The occurrence of cracks and their propagation were numerically reproduced using the concrete-damage plasticity model.

To avoid direct contact between the ship and the pier, protective structures of different types are currently widely used in bridge designs against ship impact. As one of these protective structures, the flexible floating device has drawn much attention in recent years. The main advantage of this device lies in its low cost and its ability to float on water surface regardless of water elevation. This paper aims to evaluate the effectiveness of a flexible floating anti-collision device adopted in the Zhanjiang Bay Bridge located in Guangdong Province, China, using finite-element models. Detailed illustrations of the structural configurations are provided. In addition, finite-element models of the ship and the floating device with calibrations using experimental data are developed. The influences of several factors upon the ability of the device to turn the navigation direction of the ship, the energy-dissipation capacity of the device and the effectiveness of the device for reducing the impact force on the pier, are thoroughly evaluated using the validated finite-element models. © 2019 Elsevier Ltd","Experimental data; Finite-element models; Floating device; Protective structures; Ship impact","Collision avoidance; Energy dissipation; Ships; Energy dissipation capacities; Experimental data; Floating devices; Guangdong Province; Protective structures; Ship impacts; Structural configurations; Zhanjiang Bay Bridge; Finite element method; bearing capacity; collision avoidance; data set; experimental study; finite element method; floating structure; ship technology; China; Guangdong; Zhanjiang",,,,,"National Natural Science Foundation of China, NSFC: 51278373, 51438010; Science and Technology Commission of Shanghai Municipality, STCSM: 17DZ1204300","The authors wish to thank the National Science Foundation of China (Grant Number: 51438010 , 51278373 ) and the Research Program of Shanghai Science and Technology Commission (Grant Number: 17DZ1204300 ) for supporting this research.",,,,,,,,,,"Chen, C., Study on Design Collision Force and Simulation of Damage for Bridge Subjected to Ship Impact (2006), Ph.D. thesis Department of Bridge Engineering, Tongji University Shanghai, China (in Chinese); Chen, C.J., The Performance Analysis of Floating Anti-collision Device Combined of Steel and Rubber (2017), Master's thesis Department of Bridge Engineering, Tongji University Shanghai, China (in Chinese); Chen, G.Y., Wang, L.L., Protection against Ship Bridge Collision (2006), China Railway Publishing House (in Chinese); Fan, W., Yuan, W.C., Numerical simulation and analytical modeling of pile-supported structures subjected to ship collisions including soilstructure interaction (2014) Ocean Eng., 91, pp. 11-27; Gao, Y., Hu, Z., Ringsberg, J.W., Wang, J., An elastic-plastic ice material model for ship-iceberg collision simulations (2015) Ocean Eng., 102, pp. 27-39; Getter, D.J., Davidson, M.T., Consolazio, G.R., Patev, R.C., Determination of hurricane-induced barge impact loads on floodwalls using dynamic finite element analysis (2015) Eng.

It enables us to replace high-cost shell models with stiffness-equivalent orthotropic plate alternatives. Many homogenization models for corrugated panels of different shapes have been proposed. However, there is a lack of investigations for verifying their accuracy and reliability. In addition, in the recent trend of development of smoothed finite element methods, the cell-based smoothed three-node Mindlin plate element (CS-MIN3) based on the first-order shear deformation theory (FSDT) has been proposed and successfully applied to many analyses of plate and shell structures. Thus, this paper further extends the CS-MIN3 by integrating itself with homogenization models to give homogenization methods. In these methods, the equivalent extensional, bending, and transverse shear stiffness components which constitute the equivalent orthotropic plate models are represented in explicit analytical expressions. Using the results of ANSYS and ABAQUS shell simulations as references, some numerical examples are conducted to verify the accuracy and reliability of the homogenization methods for static analyses of trapezoidally and sinusoidally corrugated panels. © 2018, Higher Education Press and Springer-Verlag GmbH Germany, part of Springer Nature.","asymptotic analysis;

Architectural structures today are increasingly complex and health monitoring plays an important role in guaranteeing their safety. Therefore, how reliability deformation monitoring can be improved is one of the key problems in the field of engineering. This paper combines the three-dimensional laser scanning technology and finite element method (FEM) to investigate the deformation mechanism of arched structures. Within this paper, we simulated arched structures using the FEM, which is consistent with the result of terrestrial laser scanner (TLS) measurement. We aimed at constructing an intelligent and efficient FEM model which can be extensively applied in the monitoring of many constructs, such as bridges and ancient architecture. The focus in this research lies mainly on deformation analysis, which is based on FEM model simulation with the calibration of TLS measurement. © 2019 Elsevier Ltd","Deformation analysis; Displacement; Finite element method; Point cloud; Terrestrial laser scanning","Arches; Deformation; Laser applications; Scanning; Steel beams and girders; Structural health monitoring; Surveying instruments; Deformation analysis; Displacement; Finite element modelling; Point cloud; Terrestrial laser scanners; Terrestrial laser scanning; Three dimensional laser scanning technology; Three-dimensional measurements; Finite element method",,,,,"Natural Science Foundation of Jiangsu Province: BK20160558","The publication of this article was funded by the support of Natural Science Foundation of Jiangsu Province (No: BK20160558 ).

This paper investigates the seismic behavior of a five-span concrete girder bridge with three coefficients of pier height and two different types of irregular configurations. Moreover, soil-structure interaction is taken into account by modeling a typical deep foundation, including piles and the surrounding soil, in order to examine the effect of pier base flexibility compared to the equivalent fixed-base model. For this purpose, incremental dynamic analyses are performed on the three-dimensional analytical finite element models using a set of ground motion pairs each rotated about the vertical axis of bridge producing seven angles of seismic incidence. The results obtained from the dynamic analyses and fragility assessment of the selected bridge models illustrate that substructure irregularity, support condition of piers, and directionality of seismic excitations are three interdependent factors in vulnerability assessment of highway bridges. Variation in each of the above-mentioned factors leads to change in the fragility characteristics of a bridge at global system failure mode or individual component limit states. © 2018 Elsevier Ltd","Fragility curves; Ground motion directionality; Incremental dynamic analysis; Irregular bridges; Soil structure interaction","Piers; Seismology; Soil structure interactions; Soils; Systems engineering; Fragility curves; Ground motions; Incremental dynamic analysis; Individual components; Irregular bridges; Performance assessment; Vulnerability assessments; Vulnerability evaluations; Highway bridges; bridge; complexity; concrete structure; dynamic analysis; failure analysis; finite element method; foundation; ground motion; performance assessment; soil-structure interaction",,,,,,,,,,,,,,,,"Priestley, M.J.N., Seible, F., Calvi, G.M., Seismic design and retrofit of bridges (1996), John Wiley & Sons, Inc Hoboken, NJ, USA; Zhu, L., Elwood, K., Haukaas, T., Classification and seismic safety evaluation of existing reinforced concrete columns (2007) J Struct Eng, 133, pp. 1316-1330; Mohammadi-Tamanani, M., Gian, Y., Ayoub, A., Design of bridges with unequal pier heights (2014) Struct Congr, pp. 677-686; Restrepo, J.O., Displacement-based design of continuous concrete bridges under transverse seismic excitation, Masters dissertation, European school for advanced studies in reduction of seismic risk (ROSE School) (2006), University of Pavia Italy; Akbari, R., Seismic fragility analysis of reinforced concrete continuous span bridges with irregular configuration (2012) Struct Infrastruct Eng, 8, pp. 873-889; Abbasi, M., Zakeri, B., Ph, D., Amiri, G.G., Probabilistic seismic assessment of multiframe concrete box-girder bridges with unequal-height piers (2013) J Perform Constr Facil; Jara, J.M., Reynoso, J.R., Olmos, B.A., Jara, M., Expected seismic performance of irregular medium-span simply supported bridges on soft and hard soils (2015) Eng Struct, 98, pp. 174-185; Kappos, A.J., Manolis, G.D., Moschonas, I.F., Seismic assessment and design of R/C bridges with irregular configuration, including SSI effects (2002) Eng Struct, 24, pp. 1337-1348; Ciampoli, M., Pinto, P.E., Effects of soil-structure interaction on inelastic seismic response of bridge piers (1995) J Struct Eng, 121, pp. 806-814; Mylonakis, G., Gazetas, G., Seismic soil-structure interaction: beneficial or detrimental?

Codified load rating can be conservative if the rating is not coupled with the field data or if simplifications are incorporated into assessment. Recent changes made to the Australian Bridge assessment code (AS 5100.7) distinguish the difference between design and assessment requirements, and include addition of structural health monitoring for bridge assessment. However, very limited guidelines are provided regarding higher order assessment levels, where more refined approaches are required to optimize the accuracy of the assessment procedure. This article proposes a multi-tier assessment procedure for capacity estimation of existing bridges using a combination of structural health monitoring techniques, advanced nonlinear analysis, and probabilistic approaches to effectively address the safety issues on aging bridges. Assessment of a Box Girder bridge was carried out according to the proposed multi-tier assessment, using data obtained from modal and destructive testing. Results of analysis at different assessment tiers showed that both load-carrying capacity and safety index of the bridge vary significantly if current bridge information is used instead of as-designed bridge information. Findings emerged from this study demonstrated that accuracy of bridge assessment is significantly improved when structural health monitoring techniques along with reliability approaches and nonlinear finite element analysis are incorporated, which will have important implications that are relevant to both practitioners and asset managers. © The Author(s) 2018.","Box Girder; Load-carrying capacity; nonlinear analysis; reliability analysis; structural health monitoring","Box girder bridges; Load limits; Loads (forces); Monitoring; Nonlinear analysis; Reliability analysis; Steel bridges; Structural analysis; Assessment procedure; Box girder; Capacity assessment; Destructive testing; Non-linear finite-element analysis; Probabilistic approaches; Reliability approach; Reliability-based load; Structural health monitoring",,,,,"Australian Research Council, ARC: DP130104133; Queensland University of Technology, QUT","The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: The research presented in this paper has been funded by Queensland University of Technology and Australian Research Council (ARC DP130104133), which are gratefully acknowledged.",,,,,,,,,,"Jamali, S., Chan, T.H.T., Thambiratnam, D.P., Pre-test finite element modelling of Box Girder overpass-application for bridge condition assessment, pp. 1-8. , Australasian structural engineering conference (ASEC), Brisbane, QLD, Australia, Engineers Australia, In; Bridge design—part 7: bridge assessment; Melchers, R.E., Beck, A.T., (2017) Structural reliability analysis and prediction, , 3rd ed., Hoboken, NJ, John Wiley & Sons; Chen, W.-F., Duan, L., (2014) Bridge engineering handbook: construction and maintenance, , 2nd ed., Boca Raton, FL, CRC Press; Lake, N., Ngo, H., Kotze, R., (2014) Review of AS 5100.7: Rating of Existing Bridges and the Bridge Assessment Group Guidelines, , Report for Austroads, Austroads Publication No. AP-R452-14, 20 February, Sydney, NSW, Australia: Austroads; Shmerling, R.Z., Catbas, F.N., Load rating and reliability analysis of an aerial guideway structure for condition assessment (2009) J Bridge Eng, 14, pp. 247-256; Taylor, P., Frauenfelder, P., Bridge Assessment for High Productivity Freight Vehicle Access: Guidelines on Processes and Procedures, , Report for Austroads, Austroads Publication No. AP-R532-16, 11 November 2016.

The numerical method is based on the novel formulation of a problem of localized erosion along a line propagating in a multidimensional porous medium. In this line, a conduit with evolving transverse size is embedded, which conveys a multiphase flow. The two systems, porous medium and pipe, are bridged by exchange terms of multiphase fluid mass and by a shared fluid pressure field. On the contrary, different fields are considered to describe flows, which are assumed as Darcian in the porous medium and turbulent in the conduit. These two flows drive pipe propagation and enlargement, respectively, as modeled by means of proper erosion kinetic laws. The corresponding numerical formulation is based on the combination between one- and multidimensional finite elements, to model the erosion conduit and the porous medium, respectively. Several simulations are proposed to demonstrate the ability of the proposed approach in reproducing available experimental data of real-scale tests on levees. Our results point out the crucial role played by the combined influence of pipe propagation and enlargement, as well as of three-dimensional (3D) effects. We also assess the mesh independence of the proposed numerical solution, particularly as concerns the calculated pipe propagation history. © 2018 John Wiley & Sons, Ltd.","backward piping; erosion; finite elements; levees; porous media","Digital storage; Embankments; Erosion; Levees; Multiphase flow; Numerical methods; Porous materials; backward piping; Fluid pressure fields; Mesh independence; Multiphase fluids; Numerical formulation; Numerical solution; Section enlargement; Three-dimensional (3D) effects; Finite element method; computer simulation; finite element method; levee; numerical model; piping; porous medium; three-dimensional modeling",,,,,"Sapienza Università di Roma; Centre National de la Recherche Scientifique, CNRS","Research supported by GIS VOR 2012, LTDS 2012, PRIN 2010-2011 (2010BFXRHS_004), and DiBT “Computational modeling of erosion” projects.

A bi-dimensional steady state FEM model has been implemented to simulate wall-to-floor structural node and then validated in accordance with the EN ISO 10211:2017 standard. Different construction joints have been then simulated for the structural node foundations-vertical elements up to a total of 19 configurations, from which 1700 cases have been derived varying walls and floor stratigraphies and ground properties. Correlations for the linear thermal bridge transmittance have been calculated through regression technique for all the configurations, together with their validity ranges expressed in terms of 95% confidence interval values. Tests performed for more than 1000 practical cases confirmed the accuracy of the proposed correlations. Through those correlations ground contact thermal bridges in existing buildings can be hence analyzed in a simple and operative way, offering technicians in the sector a tool that covers most of the possible situations. © 2020 Elsevier B.V.","Building envelope; Finite elements; Linear thermal transmittance; Thermal bridge","Floors; Confidence interval; Construction joints; FEM modeling; Ground contacts; Regression techniques; Steady state; Thermal bridge; Walls (structural partitions)",,,,,,,,,,,,,,,,"Rees, S.W., Adjali, M.H., Zhou, Z., Davies, M., Thomas, H.R., Ground heat transfer effects on the thermal performance of earth-contact structures (2000) Renew.

It is generally expected that adverse effects of residual stresses on both cross-section and member resistances in the S690 CFCHS are proportionally less pronounced, when compared with those in S355 CFCHS owing to increased yield strengths of the steels. Hence, there is a need to determine the distribution of residual stresses in the S690 CFCHS through a rational experimental and numerical investigation in order to provide accurate data for subsequent structural assessment on these sections. A total of four S690 CFCHS are fabricated with 6 mm thick plates with (i) transverse bending, and (ii) longitudinal welding. Surface temperature history at selected positions of these sections are measured with thermocouples during welding while surface residual stresses are measured with the sectioning method after welding. Owing to various practical constraints in measuring residual stresses of these sections accurately, a total of three coordinated finite element models are established in which their numerical results are integrated for rational analyses. The transverse bending process is simulated with two-dimensional models with plane-strain elements which undergo extensive plastic deformations to generate residual stresses after springback. The longitudinal welding process is simulated with two coupled three-dimensional models with solid elements to perform a sequentially-coupled thermomechanical analysis in the presence of those residual stresses due to transverse bending. Consequently, a rational distribution of the residual stresses due to both transverse bending and longitudinal welding in these sections are readily determined with these coordinated finite element models after careful calibration against measured data. © 2020 Elsevier Ltd","Bending; Cold-formed circular hollow sections; High strength steels; Residual stresses; Thermomechanical analysis; Welding","Box girder bridges; Residual stresses; Strain; Thermocouples; Welding; Circular hollow section; Coupled thermomechanical analysis; Distribution of residual stress; Numerical investigations; Structural assessments; Surface residual stress; Three-dimensional model; Two dimensional model; Finite element method; bending; finite element method; residual stress; steel; structural analysis; thermomechanics; welding",,,,,"152157/18, 152231/17E, 152687/16E, PolyU 152194/15E; Hong Kong Polytechnic University, PolyU: 1-BBV3, 1-BBY3","The research work leading to publication of this paper was supported by a comprehensive research and development programme on effective use of high strength S690 steels in construction undertaken at the Chinese National Engineering Research Centre for Steel Construction (Hong Kong Branch) supported by the Innovation and Technology Fund of the Government of Hong Kong SAR and the Research Committee of the Hong Kong Polytechnic University (Project Nos. 1-BBY3 and 1-BBV3).

Impressively, it is mainly composed of aragonite, a brittle ceramic, but boasts a high fracture toughness. Understanding and mimicking the unique mechanisms of the structure of conch shells can toughen lightweight materials. However, due to the complexity of the hierarchical architecture of conch, studies have focused on mimicking it as a bi-material composite. In this research, 3D printing is employed to develop a proof-of-concept single edge notched panel that mimics the composite structure of conch. The instructions (G-code) of the dual extrusion 3D printer were programmed to produce a multi-layer composite architecture. The conch-like panel was tested under tension, and a numerical model was developed and validated using experimental observations. Parametric studies were conducted to improve the performance of the conch-like structure. The conch-like panel was benchmarked against a bulk panel and showed noticeable improvements in strength and toughness. Several key parameters were identified, which can guide the future design of lightweight materials for applications requiring high energy dissipation. This preliminary proof-of-concept study can thereby guide the development of more complex bio-mimetic structures for protective applications. © 2020 Elsevier Ltd","3D printing; Bio-mimetic; Conch shell; eXtended finite element method; G-code; Lamellae structure","Biomimetics; Energy dissipation; Fracture toughness; Shells (structures); Tensile strength; Brittle ceramics; Hierarchical architectures; Lightweight materials; Multilayer composite; Parametric study; Quasi-static loading; Single edge notched; Strength and toughness; 3D printers",,,,,"Australian Research Council, ARC: DP170100851","This research was funded through the ARC Discovery Project DP170100851.",,,,,,,,,,"Kamat, S., Fracture mechanisms of the Strombus gigas conch shell: II-micromechanics analyses of multiple cracking and large-scale crack bridging (2004) Acta Mater, 52 (8), pp. 2395-2406; Kuhn-Spearing, L., Fracture mechanisms of the Strombus gigas conch shell: implications for the design of brittle laminates (1996) J Mater Sci, 31 (24), pp. 6583-6594; Shin, Y.A., Nanotwin-governed toughening mechanism in hierarchically structured biological materials (2016) Nat Commun, 7, p. 10772; Salinas, C.L., Enhanced toughening of the crossed lamellar structure revealed by nanoindentation (2017) J Mech Behav Biomed Mater, 76, pp. 58-68; Zhang, Z., Zhang, Y.-W., Gao, H., On optimal hierarchy of load-bearing biological materials (2011) Proc R Soc B, 278 (1705), pp. 519-525; Karambelas, G., Santhanam, S., Wing, Z.N., Strombus gigas inspired biomimetic ceramic composites via SHELL—Sequential Hierarchical Engineered Layer Lamination (2013) Ceram Int, 39, pp. 1315-1325; Kamat, S., Structural basis for the fracture toughness of the shell of the conch Strombus gigas (2000) Nature, 405, pp. 1036-1040; Menig, R., Quasi-static and dynamic mechanical response of Strombus gigas (conch) shells (2001) Mater Sci Eng A, 297, pp. 203-211; Li, H., Xu, Z.-H., Li, X., Multiscale hierarchical assembly strategy and mechanical prowess in conch shells (Busycon carica) (2013) J Struct Biol, 184 (3), pp. 409-416; Lin, A.Y.M., Meyers, M.A., Vecchio, K.S., Mechanical properties and structure of Strombus gigas, Tridacna gigas, and Haliotis rufescens sea shells: a comparative study (2006) Mater Sci Eng, C, 26 (8), pp. 1380-1389; Li, H., Dynamic self-strengthening of a bio-nanostructured armor-conch shell (2019) Mater Sci Eng, C; Romana, L., Use of nanoindentation technique for a better understanding of the fracture toughness of Strombus gigas conch shell (2013) Mater Charact, 76, pp. 55-68; Chen, L., Bioinspired micro-composite structure (2007) J Mater Res, 22 (1), pp. 124-131; Gu, G.X., Takaffoli, M., Buehler, M.J., Hierarchically enhanced impact resistance of bioinspired composites (2017) Adv Mater, 29 (28), p. 1700060; Jia, Z., Wang, L., (2018), 3D Printing of Biomimetic Composites with Improved Fracture Toughness.

Many compliant mechanisms derive their design ideas from nature, since the structure of biological organisms sometimes offers a better solution than the conventional mechanisms. However, the bio-inspired structures usually have very complex geometries which cannot be easily modeled and analyzed using traditional methods. In this paper, we present a novel finite element method (FEM) based modeling framework in MATLAB to analyze the mechanics of different bio-inspired compliant mechanisms. Since the basic linear FEM formulation can only be employed to model small displacements of compliant mechanisms, a non-linear FEM formulation that integrates the modeling of large displacements, tendon-driven mechanisms and contact problems was implemented in the proposed framework to overcome the limitations. Simulations and experiments were also conducted to evaluate the performance of the modeling framework. Results have demonstrated the accuracy and plausibility of the proposed non-linear FEM formulation. Furthermore, the proposed framework can also be used to achieve structural optimization of bio-inspired compliant mechanisms. © 2018 IEEE.","biomimetics; compliant mechanism; Finite element method","Agricultural robots; Biomimetics; Bridge components; Finite element method; MATLAB; Mechanisms; Medical applications; Medical robotics; Structural design; Structural optimization; Biological organisms; Complex geometries; High flexibility; Large displacements; Mechanics modeling; Monolithic structures; Small displacement; Tendon-driven mechanisms; Compliant mechanisms",,,,,,"This work was supported by the Munich School of Robotics and Machine Intelligence, Technical University of Munich, Munich, Germany.",,,,,,,,,,"Frecker, M.I., Dziedzic, R., Haluck, R., Design of multifunctional compliant mechanisms for minimally invasive surgery (2002) Minim.

Recently, many studies have been conducted to investigate scour effects on lateral behavior of single piles using numerical analyses, laboratory model tests, or centrifuge tests. However, very limited research is focused on scour effects on lateral behavior of pile groups. No simple method is currently available for practicing engineers to analyze pile groups under scour conditions. In this study, a simple and practical method was proposed based on the existing p-y curve theory to facilitate the design of laterally loaded pile groups under scour conditions. Feasibility of the proposed method was examined against 3D finite element (FE) analyses through a series of parametric studies by varying scour-hole dimensions, soil properties, and pile group configurations. The results showed that the proposed method generally produced agreeable results with the 3D FE analyses. Scour-induced lateral capacity loss of pile groups was 10–13% more in dense sands than in loose sands. Pile groups were more susceptible to scour than single piles under the equivalent scour conditions. A pile group with smaller pile spacing and larger pile numbers showed a less loss of lateral capacity due to scour. © 2020","Lateral behavior; Local scour; Numerical method; Pile groups","Failure (mechanical); Fracture mechanics; Offshore structures; Scour; Soil testing; Centrifuge tests; Laboratory model test; Lateral capacity; Laterally loaded pile groups; Parametric study; Practical method; Practicing engineers; Structural failure; Piles; design; feasibility study; finite element method; pile group; sand; scour; soil property; three-dimensional modeling",,,,,"Natural Sciences and Engineering Research Council of Canada, NSERC","The authors would like to acknowledge the support by Natural Sciences and Engineering Research Council of Canada (NSERC) through a discovery grant.",,,,,,,,,,"AASHTO (American Association of State Highway and Transportation Officials), AASHTO LRFD Bridge Design Specifications (2012), seventh ed.

Drop hammer tests were performed to determine the mechanical behaviour and failure modes of different specimens. Further, numerical simulations were performed to analyse the damage evolution during the impact process, and the effect of lamination sequence on the transverse impact performance was analysed. The results show that under impact energies of 5 and 10 J, the tubes tend to generate circumferential cracks. When the impact energy is between 15 and 30 J, the tubes absorb energy by generating circumferential and longitudinal cracks. The damage evolution of the tubes can be better understood through the simulation results. When the ply angle increases from 0° to 75°, the fracture mode of the tube changes from a longitudinal to a circumferential crack. Tubes with complex ply angles have better energy absorption performance. © 2020 Elsevier Ltd","Carbon fibre reinforced polymers; Continuous damage model; Damage analysis; Finite element analysis; Transverse impact behaviour","Beams and girders; Bridge decks; Carbon fiber reinforced plastics; Cracks; Fatigue crack propagation; Finite element method; Polymers; Reinforcement; Tubes (components); Absorption performance; Carbon fibre reinforced polymer; Circumferential cracks; Damage analysis; Damage model; Longitudinal cracks; Mechanical behaviour; Transverse impact; Carbon fibers",,,,,"National Natural Science Foundation of China, NSFC: 51775227 ＆ 51375201","This work was supported by the National Natural Science Foundation of China (Grant Nos. 51775227 ＆ 51375201 ).",,,,,,,,,,"Hesse, S.H., Lukaszewicz, H.J.A., Duddeck, F., A method to reduce design complexity of automotive composite structures with respect to crashworthiness (2015) Compos.

The tension of the hanger cables of a suspension bridge is a very important parameter for assessing the integrity and safety of the bridge. In general, indirect methods are used to measure the tension of the hanger cables of a suspension bridge in use. A representative indirect method is the vibration method, which extracts modal frequencies from the cables' responses and then measures the cable tension using the cables' geometric conditions and the modal frequencies. In this study, ambient vibration tests were conducted on a suspension bridge in use to verify the validity of the image-based back analysis method, which can estimate the tension of remote hanger cables using the modal frequencies as a parameter. The tension estimated through back analysis, which was conducted to minimize the difference between the modal frequencies calculated using finite element analysis of the hanger cables and the measured modal frequencies, was compared with that measured using the vibration method. It was confirmed that reliable tension estimation is possible even with low-order modal frequencies when the image-based back analysis method is used. © 2020 John Wiley & Sons, Ltd.","cable tension; hanger cable; image-based back analysis method; long-span bridge","Frequency estimation; Image analysis; Modal analysis; Suspension bridges; Vibration analysis; Ambient vibration test; Back analysis method; Cable tension; Geometric conditions; Indirect methods; Long-span bridge; Tension estimation; Vibration method; Bridge cables",,,,,"Ministry of Education, MOE: NRF‐2017R1D1A3B03035169; National Research Foundation of Korea, NRF","This research was supported by Basic Science Research Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Education (NRF‐2017R1D1A3B03035169).

The precise motion of the microgripper jaw is required to achieve high performance micromanipulation tasks. The parasitic motion of the microgripper reduces placement accuracy during pick and place tasks. This paper presents an asymmetric design of piezoelectric actuated microgripper. It investigates key characteristics including parasitic motion, output displacement, and displacement amplification ratio. The microgripper is designed with a single-stage displacement amplification mechanism to form a compact layout. The design of the microgripper integrates the bridge-type mechanism and the parallelogram mechanisms. The bridge-type mechanism amplifies the piezoelectric actuator output and the parallelogram mechanisms offer linear motion of the gripper jaw. The analytical modeling and finite element analysis were conducted to evaluate the characteristics of the microgripper. The design parameters of the microgripper were optimized through several finite element analysis. Further, experimental studies were conducted to verify the characteristics of the microgripper. The parasitic motion of the jaw was obtained as less than 0.18% of the microgripper jaw motion in the x-direction. The mechanism of the microgripper also achieves a high positioning accuracy. Further, a high displacement amplification ratio and large output displacement can be achieved. © 2020 IOP Publishing Ltd.",,"Bridges; Finite element method; Mechanisms; Piezoelectric actuators; Piezoelectricity; Advanced manufacturing technologies; Bridge-type mechanisms; Displacement amplification; Displacement amplification mechanisms; Experimental investigations; Micro/nano manipulation; Parallelogram mechanisms; Positioning accuracy; Grippers",,,,,,,,,,,,,,,,"Kim, K., Liu, X., Zhang, Y., Sun, Y., Nanonewton force-controlled manipulation of biomaterials using a monolithic MEMS microgripper with two-axis force feedback (2008) J.

This framework can provide bridge designers and engineering practitioners with a general platform to analyze the coupled system with high modeling efficiency and accuracy in modeling and outputting. Moreover, it has readily available nonlinear material/element models and nonlinear dynamic analysis functions for complex structures. This analysis framework was first validated with a classical VBI problem involving a sprung mass moving on a simply supported beam, whose closed-form solution is readily available. Validation for the application on complex structure was then presented with a typical 16-car Japanese high-speed train (Shinkansen) and a three-block bridge. The cars comprised car bodies, bogies and wheelsets, which were all modeled as rigid bodies and which were connected with springs and dashpots. The bridge was modeled with typical three-dimensional solid elements. Interaction between wheelsets and tracks was realized using the penalty method. Rail irregularity was also considered in the analysis. The consistency between calculated dynamic responses and field experiment data of certain pre-specified observation points validated the proposed method. Furthermore, ease in analyzing VBI problems involving nonlinear material properties and with high spatial resolutions was demonstrated with a classical cracked beam problem: a point mass moving on a simply supported cracked beam. Both linear and nonlinear crack models were employed. The former model assigned crack surfaces with a mechanical contact property and showed its accuracy in comparison to the reference model. The latter assigned a nonlinear material model in crack-prone zones and illustrated the potential applicability to dynamic crack propagation simulation in VBI problems. The present framework was further applied to seismic response analysis of a train-bridge interaction system involving material nonlinearity and separation between track and wheel under a strong earthquake. © 2020 World Scientific Publishing Company.","Cracked structure; finite element package; high-speed railway; nonlinear analysis; penalty method; vehicle-bridge interaction","ABAQUS; Automobile bodies; Commercial vehicles; Constrained optimization; Cracks; Earthquakes; Nonlinear analysis; Railroad bridges; Railroad cars; Railroad transportation; Railroads; Wheels; Cracked structures; Finite element packages; High - speed railways; Penalty methods; Vehicle-bridge interaction; Finite element method",,,,,"China Scholarship Council, CSC: 201606090201","Xuzhao Lu was sponsored by the China Scholarship Council No. 201606090201).",,,,,,,,,,"Zhang, N., Xia, H., Guo, W.W., De Roeck, G., A vehicle-bridge linear interaction model and its validation (2010) Int.

Previous studies on this topic are limited especially for thrust faults. It is necessary to examine the performances of fault-crossing bridges subjected to earthquake-induced surface fault rupture. This study investigates the seismic behavior of a recently proposed steel-concrete composite rigid-frame bridge (SCCRFB) with concrete-filled double skin steel tube (CFDST) piers subjected to the earthquake-induced surface rupture at a thrust fault. Shake table tests on a 1:10 scaled three-span SCCRFB subjected to across-fault ground motions were performed first. Detailed 3D finite element (FE) model of the bridge is then developed by using LS-DYNA and validated by the experimental results. The effects of the key parameters that influence the bridge responses to surface ruptures including the location of the fault, fault-crossing angle and fling-step are systematically investigated. Experimental and numerical results reveal that this novel bridge type has a very good seismic resistance capability. © 2019 Elsevier Ltd","Numerical simulation; SCCRFB with CSDST piers; Shake table test; Surface rupture; Thrust fault","Composite structures; Computer simulation; Concretes; Earthquake effects; Earthquake engineering; Piers; Rigidity; Seismic response; Tubular steel structures; 3D finite element model; Concrete filled doubleskin steel tube (CFDST); Experimental and numerical studies; Rigid-frame bridges; Shake table tests; Steel-concrete composite; Surface ruptures; Thrust faults; Faulting; bridge; concrete structure; dynamic response; finite element method; numerical model; seismic response; shaking table test; steel structure; thrust fault",,,,,"KYCX17_0128; National Natural Science Foundation of China, NSFC: 51678141; China Scholarship Council, CSC; National Key Research and Development Program of China, NKRDPC: 2017YFC0703405; Fundamental Research Funds for the Central Universities","This study was supported by the National Key Research and Development Program of China (No. 2017YFC0703405 ), and the National Natural Science Foundation of China (No. 51678141 ).

Most existing studies focus on numerical and experimental models. More studies on large-scale civil infrastructures based on field monitoring are still required. A case study on Bayesian FEM updating of the Runyang Suspension Bridge (RSB), a long-span suspension bridge with a main span of 1,490 m, is carried out in this paper. The Bayesian updating method is utilized to update the initial FEM of RSB, aiming to make the numerical modal properties match the field monitoring results. Two stochastic sampling algorithms, i.e., the Metropolis-Hastings (MH) algorithm and the Hybrid Monte Carlo (HMC) algorithm, are respectively investigated to show their advantages and limitations in Bayesian updating. Subsequently, based on the experimentalsamples generated by the Latin hypercube sampling algorithm, a Kriging predictor is established as a surrogate model to reduce the computational burden of model updating. Results show that the HMC algorithm could guarantee much higher acceptance rate of the sampled chain than the MH algorithm especially when the updating step size is large. In addition, combined with the Kriging predictor, Bayesian model updating method could serve as an effective and efficient tool to calibrate the FEM of large-scale civil infrastructures. © 2020, Korean Society of Civil Engineers.","Bayesian model updating; Finite element model; Hybrid monte carlo; Kriging predictor; Long-span bridges","Bayesian networks; Intelligent systems; Interpolation; Learning algorithms; Monte Carlo methods; Numerical methods; Stochastic systems; Suspension bridges; Bayesian model updating; Bayesian updating method; Finite-element model updating; Hybrid Monte Carlo; Hybrid monte carlo simulations; Kriging; Long span suspension bridges; Long-span bridge; Finite element method",,,,,"KYCX17_0127; National Natural Science Foundation of China, NSFC: 51722804, 51978155; National Postdoctoral Program for Innovative Talents: W03070080; Scientific Research Foundation of the Graduate School of Southeast University: YBJJ1761; Jiangsu Provincial Key Research and Development Program: BE2018120","The authors would like to gratefully acknowledge the support from the National Natural Science Foundation of China (51722804 and 51978155), the National Ten Thousand Talent Program for Young Top-Notch Talents (W03070080), the Jiangsu Provincial Key Research and Development Program (BE2018120).

Most of them were built as part of the post-World War II reconstruction effort, meaning that we, as society, are already facing the beginning of the end of their design life. This shows the necessity of efficient approaches, complementing visual inspections, for early detection of damage that might jeopardise structural integrity and ultimately might lead to loss of life. This work introduces a novel, pro-active structural health monitoring (SHM) approach to better identify and quantify representative damage types, on prestressed concrete bridges. Based on a numerical simulation of a comprehensive case study available in the literature: the Lezíria Bridge, the results show that damage can be identified with good accuracy for early stages of damaged bridges. Pier settlements and prestress losses are the damage types where the severity is quite accurately quantified even for lower damage severity levels. Once the damage type is identified, it is found that a pair of two vertical displacements reveals to be enough to quantify the damage extent. The results also show potential in the utilisation of the approach for a rational and efficient design of monitoring systems towards damage identification. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.","Bayesian statistics; bridge management; Bridges; damage; finite element modelling; measurement uncertainty; response surface modelling; structural health monitoring","Bayesian networks; Bridges; Chemical detection; Finite element method; Military operations; Prestressed concrete; Structural health monitoring; Uncertainty analysis; Bayesian statistics; Bridge management; damage; Finite element modelling; Measurement uncertainty; Response surface modelling; Damage detection",,,,,"European Cooperation in Science and Technology, COST: TU1402","This work was funded by European Cooperation in Science and Technology.

Their failure can be detrimental to the structure; therefore, various studies on predicting their mechanical characteristics have been conducted. However, explaining the mechanical characteristics of steel strands is difficult because of geometric complexity, difficulty in corrosion modeling, and various uncertain factors. This paper proposes a new method for the probabilistic prediction of the mechanical characteristics of corroded steel strands. First, finite element (FE) models are built for several types of corroded wires. Second, based on the FE analysis results, a nonparametric surrogate model is constructed using Gaussian process regression. Third, the ultimate strength and strain of the corroded steel strands are predicted probabilistically by conducting a Monte Carlo simulation with a theoretical strand model. As a result, the probabilistic ranges of 50% and 95% are estimated. Based on the prediction results, appropriate probabilistic distributions for the ultimate strength and strain are studied. The proposed method is applied to several specimens of corroded seven-wire strands. The prediction results are in good agreement with the test results. Additionally, a failure probability assessment is conducted as an application example based on the goodness-of-fit test. © 2019 Elsevier Ltd","Corroded steel strand; Mechanical characteristics; Monte Carlo simulation; Probabilistic prediction; Surrogate model","Corrosive effects; Forecasting; Intelligent systems; Mechanical properties; Monte Carlo methods; Probability distributions; Application examples; Gaussian process regression; Geometric complexity; Mechanical characteristics; Probabilistic distribution; Probabilistic prediction; Steel strand; Surrogate model; Steel corrosion; computer simulation; corrosion; finite element method; mechanical property; Monte Carlo analysis; prediction; probability; steel structure",,,,,"Ministry of Land, Infrastructure and Transport, MOLIT; Korea Agency for Infrastructure Technology Advancement, KAIA: 20SCIP-B128570-04","This study was supported by a grant from the Smart Civil Infrastructure Research Program funded by the Ministry of Land, Infrastructure and Transport (MOLIT) of the Korean government and the Korea Agency for Infrastructure Technology Advancement (KAIA) [ 20SCIP-B128570-04 ].

These factors lead to an increase in dynamic effects and necessitate the use of non-classical design schemes of artificial structures of the transport infrastructure. In the present study, it is proposed to use a three-span arch bridge crossing with a suspension central span structure as the basis for a unified bridge crossing; such an arrangement will allow changing the design length of the central span in a fairly wide range, reduce the total number of supports with an increase in the total length of the bridge crossing, and use such a design as a double-track railway, two- or four-lane road bridge. The calculations and the obtained results of assessing the displacements, internal forces and stresses in the nodes and elements of the proposed bridge crossing design allow us to conclude that the allowable limit magnitudes of the values found are sufficiently uniform load of all the main elements, the absence of pronounced large-scale stress concentrators. © 2020, Springer Nature Switzerland AG.","Bridge crossings; Finite element method; Overpasses; Railway devices crossings","Arch bridges; Crossings (pipe and cable); Finite element method; Highway bridges; Overpasses; Railroads; Reinforced concrete; Artificial structures; Bridge crossing; Dynamic effects; Internal forces; Movement speed; Span structures; Transport infrastructure; Transport line; Structural design",,,,,,,,,,,,,,,,"Alexey, A.L., Vadim, V.K., Irina, V.S., Dmitry, A.B., Modeling the dynamic behavior of the upper structure of the railway track (2017) Procedia Eng, 189, pp. 133-137. , https://doi.org/10.1016/j.proeng.2017.05.022, Transportation Geotechnics and Geoecology, TGG 2017, 17–19 May 2017, Saint Petersburg, Russia; Glusberg, B., Korolev, V., Shishkina, I., Loktev, A., Shukurov, J., Geluh, P., Calculation of track component failure caused by the most dangerous defects on change of their design and operational conditions (2018) MATEC Web Conf., 239. , https://doi.org/10.1051/matecconf/201823901054; Loktev, A.A., Korolev, V.V., Shishkina, I.V., High frequency vibrations in the elements of the rolling stock on the railway bridges (2018) IOP Conf.

As a result, the determination of parameters becomes an important issue from models to engineering practice. This paper aims to propose a straightforward method for parameters determination from standard laboratory tests. First, a recently developed simple critical state-based sand model is adopted with non-linear critical state line and some key parameters. Based on this model, the derivation of all constitutive equations is made to propose a straightforward procedure for determining parameters. The conventional drained triaxial tests performed on Toyoura sand are selected as example for clarifying and validating the procedure. Furthermore, the model is implemented into a finite element code, and numerical modelling of a series footing and pile penetration tests is performed using the straightforwardly determined parameters. Overall, the proposed procedure is validated as an efficient and reliable bridge from critical state-based constitutive modelling to finite element analysis. © 2017, © 2017 Informa UK Limited, trading as Taylor & Francis Group.","constitutive model; critical state; finite element; foundation; Sand; triaxial test","Constitutive equations; Constitutive models; Critical current density (superconductivity); Foundations; Piles; Sand; Critical state; Critical state lines; Determination of parameters; Drained triaxial tests; Engineering practices; Finite element codes; Parameters determination; Straight-forward method; Finite element method",,,,,"National Natural Science Foundation of China, NSFC: 41372285, 51579179","The work was supported by the National Natural Science Foundation of China [grant number 41372285], [grant number 51579179]; the Region Pays de la Loire of France [project RI-ADAPTCLIM].",,,,,,,,,,"Bauer, E., Conditions for embedding Casagrande’s critical states into hypoplasticity (2000) Mechanics of Cohesive-frictional Materials, 5, pp. 125-148; Been, K., Jefferies, M.G., A state parameter for sands (1985) Géotechnique, 35, pp. 99-112; Biarez, J., Hicher, P.Y., (1994) Elementary mechanics of soil behaviour: Saturated remoulded soils, , Rotterdam: AA Balkema; Chang, C., Yin, Z.Y., Hicher, P.Y., Micromechanical analysis for interparticle and assembly instability of sand (2010) Journal of Engineering Mechanics, 137, pp. 155-168; Fioravante, V., Giretti, D., Unidirectional cyclic resistance of Ticino and Toyoura sands from centrifuge cone penetration tests (2016) Acta Geotechnica, 11, pp. 953-968. , 4; Gajo, A., Muir Wood, D., A kinematic hardening constitutive model for sands: The multiaxial formulation (1999) International Journal for Numerical and Analytical Methods in Geomechanics, 23, pp. 925-965; (1998), Natick, MA 5, 333; (2001) Sorensen, , ABAQUS/explicit, User’s manual.

However, the fatigue damage of rib-to-deck welded joint in OSD is one of the most challenging issues. The notch stress intensity factors (NSIFs) that characterize the local mechanical properties of notch tips are major parameters for fatigue evaluation of rib-to-deck welded joint. This paper proposes formulae of the NSIFs of weld root for rib-to-deck welded joint under deck loading modes. First, parametric studies are conducted using a finite element model to establish a holistic understanding of the effects of the geometrical parameters on the NSIFs. The investigated parameters include the weld penetration rate, relative weld height, deck toe flank angle, and plate thickness ratio. Then, multi-parameter analysis is carried out based on the data generated from the parametric study. Finally, the proposed formulae of the NSIFs are evaluated and applied to evaluate the stress distribution and the averaged strain energy density of single-weld specimens for rib-to-deck welded joints. The maximum error of 9.5% indicates that the NSIFs predicted using the proposed formulae are in good agreement with the finite element analysis results. The proposed formulae provide useful tools for determining the stress distributions and the averaged strain energy density of single-weld rib-to-deck welded joint specimens. © 2019 Elsevier Ltd","Fatigue evaluation; Finite element analysis; Multi-parameter regression; Notch stress intensity factor; Weld root","Bridges; Fatigue of materials; Finite element method; Geometry; Parameter estimation; Strain energy; Stress analysis; Stress concentration; Stress intensity factors; Welding; Bridge engineering; Fatigue evaluation; Local mechanical properties; Multiparameters; Notch stress intensity factors; Orthotropic steel decks; Strain energy density; Weld penetrations; Welds",,,,,"2011BAG07B03; BHSKL18-01-KF; National Natural Science Foundation of China, NSFC: 51578455, 51778533, 51878561; China Scholarship Council, CSC: 201807000074; Department of Science and Technology, Hubei Provincial People's Government: 2017-538-2-4; Fundamental Research Funds for the Central Universities: 2682014CX078","This study was funded by the National Natural Science Foundation of China [grant numbers 51878561, 51778533, 51578455], Science and Technology Program of Hubei Transportation Department [grant number 2017-538-2-4], Fundamental Research Funds for the Central Universities [grant number 2682014CX078], National Science and Technology Support Program of China [grant number 2011BAG07B03], and Open Key Fund Sponsored Program of State Key Laboratory for Bridge Health and Safety [grant number BHSKL18-01-KF].

However, less is known about FCs in fibrous materials, such as the networks composing the extracellular matrix (ECM) of biological systems. Using a finite-element computational model, we simulated the contraction of a single cell and two nearby cells embedded in two-dimensional fibrous elastic networks and analysed the tensile FCs that developed in the ECM. The role of ECM nonlinear elasticity on FC formation was evaluated by considering linear and nonlinear, i.e. exhibiting ‘buckling’ and/or ‘strain-stiffening’, stress–strain curves. The effect of the degree of cell contraction and network coordination value was assessed. We found that nonlinear elasticity of the ECM fibres influenced the structure of the FCs, facilitating the transition towards more distinct chains that were less branched and more radially oriented than the chains formed in linear elastic networks. When two neighbouring cells contract, a larger number of FCs bridged between the cells in nonlinear networks, and these chains had a larger effective rigidity than the chains that did not reach a neighbouring cell. These results suggest that FCs function as a route for mechanical communication between distant cells and highlight the contribution of ECM fibre nonlinear elasticity to the formation of FCs. © 2019 The Author(s) Published by the Royal Society.

To this end, this work proposes a simplified analytical model for predicting the time-history of ship impact loading on bridges. To validate the FE modeling techniques used in capturing the impact loading, drop hammer impact tests are carried out using scaled steel boxes. Then FE models of 5 typical ships are developed and numerical simulations are conducted to generate the 45 benchmark impact force time-history curves which are used to determine the parameters introduced in the proposed simplified analytical model. The efficiency of the proposed model is evaluated by a case study involving two bridge models, as presented in this paper. It is shown that the proposed simplified analytical model is capable of predicting the time-history of impact loading with sufficient accuracy for ship-bridge collision events when the basic structural frequency of the bridge pier is within 3 Hz. © 2019","Dynamic amplification effects; Impact test; Numerical simulation; Ship-bridge collision; Simplified analytical model","Bridges; Computer simulation; Concrete bridges; Impact testing; Numerical models; Ships; Bridge design; Drop hammers; Dynamic amplification; Impact loadings; Ship bridge collisions; Ship collision; Static forces; Structural frequencies; Analytical models; amplification; analytical method; bridge; computer simulation; finite element method; numerical model; ship motion",,,,,"2018YFC1504306; National Natural Science Foundation of China, NSFC: 51438010, 51778498; Science and Technology Commission of Shanghai Municipality, STCSM: 17DZ1204300","The research is supported by the National Science Foundation of China (Grant Number: 51438010 , 51778498 ), the Research Program of Shanghai Science and Technology Committee (Grant Number: 17DZ1204300 ) and the National Key R&D Program of China (Grant Number: 2018YFC1504306 ).",,,,,,,,,,"AASHTO, Guide Specifications and Commentary for Vessel Collision Design of Highway Bridges (1991), American Association of State Highway and Transportation Officials Washington, DC; B02-01-2008, Guidelines for Seismic Design of Highway Bridges (2008), China Communications Press Beijing (in Chinese); Chopra, A.K., Dynamics of Structures: Theory and Applications to Earthquake Engineering (2012), Prentice Hall; Consolazio, G.R., Cook, R.A., Biggs, A., Cowan, D., Barge Impact Testing of the St. George Island Causeway Bridge.

This paper develops a theoretical analysis method, which is designated as PM analysis for analyzing shear lag phenomenon in thin-walled box-section beam with arbitrary width of cantilever flange. In this method, the introduction of initial shear rotation (or initial shear strain) γ 0i , due to the effect of web restraint on flanges, is innovatively proposed and further employed in describing the additional warping displacement in top lateral cantilever flanges, and a practical and straightforward procedure of coefficient α 3 is designed (DP) based on the proposed assumptions. In addition, a modified method to PM-DP analysis is developed for improving the defects of the hypothesis of shear-lag warping displacements in top lateral cantilever flanges, that is, PM-DP(M) analysis. The differential equations for generalized displacement w(x) and the standard magnitude of shear-lag warping displacement U(x) of the beam are deduced by means of the principle of minimum potential energy (MPE) and solved with the given boundary conditions. Numerous models of thin-walled box-section with arbitrary width of top lateral cantilever flanges under distributed load are chosen and built through a software program (ABAQUS). The results obtained from PM analysis (PM-LB, PM-DP and PM-DP(M)) are summarized into a series of curves indicating the distribution of normal stress and the displacements for various examples, and compared to those obtained from the finite element method (FEM). The study widely demonstrates the strong applicability and high precision of PM-DP(M) analysis, which can be considered as an ideal solution in predicting shear lag effect for thin-walled box-section beam with arbitrary width of cantilever flange and, possibly, be adopted as valuable reference for the design of related thin-walled structures. © 2019 Elsevier Ltd","Designed procedure; Finite element method; Initial shear rotation; Shear lag phenomenon; Theoretical analysis method; Thin-walled box-section beam","ABAQUS; Boundary conditions; Box girder bridges; Fasteners; Fiber optic sensors; Flanges; Nanocantilevers; Potential energy; Shear flow; Shear strain; Thin walled structures; Analysis method; Designed procedure; Shear lag; Shear rotation; Thin-walled box sections; Finite element method",,,,,"University of Houston, UH; National Natural Science Foundation of China, NSFC: 50078014; China Scholarship Council, CSC: 201606090145","Funds by the National Natural Science Foundation of China (Grant No.50078014) and China Scholarship Council (No.201606090145) to provide financial support for the first author to visit the University of Houston is gratefully acknowledged.","Funds by the National Natural Science Foundation of China (Grant No. 50078014 ) and China Scholarship Council (No. 201606090145 ) to provide financial support for the first author to visit the University of Houston is gratefully acknowledged.",,,,,,,,,"Reissner, E., Analysis of shear lag in box beams by the principle of minimum potential energy (1946) Q.

We effectively utilized these scissors mechanism features to develop a lightweight, deployable emergency Mobile Bridge (MB) based on optimization, and control of the folding structure. Here, we discuss the problems of optimal reinforcement layout for the MB by formulating and solving three optimization problems, namely: (a) the load capacity maximization problem, (b) the weight minimization problem, and (c) coupling the load capacity maximization problem and the weight minimization problem. The potential benefits resulting from the application of reinforcement were evaluated using a combination of finite element analysis and an optimization algorithm based on the differential evolution method. The results demonstrate the significant positive influence of the additional reinforcing members. In particular, the limit load was increased by over 10 times, while the weight was decreased to approximately half. The proposed methodology enabled the development of a substantially improved version of the MB characterized by a higher load capacity and lower weight in comparison to the initial bridge design. © 2019 Computer-Aided Civil and Infrastructure Engineering",,"Bridges; Evolutionary algorithms; Optimization; Reinforcement; Reusability; Safety engineering; Tools; Differential evolution algorithms; Differential evolution method; Maximization problem; Optimization algorithms; Optimization of reinforcement; Optimization problems; Reinforcement layout; Temporary structures; Problem solving; algorithm; bridge; design method; finite element method; optimization; reinforcement; transportation infrastructure; weight",,,,,"Japan Society for the Promotion of Science, JSPS; Polska Akademia Nauk","The Japan Society for the Promotion of Science (JSPS); Polish Academy of Sciences; Uragami scholarship foundation","The research was supported by the Bilateral Program between the Japan Society for the Promotion of Science (JSPS) and Polish Academy of Sciences (PAN) in 2016?2018 and by the Uragami scholarship foundation in 2014?2015.

Extending from traditional integer order IMs, this study assesses the performance of fractional order (FO, order of α) IMs on the probabilistic seismic demand modeling of extended pile-shaft supported bridges sited in liquefiable and laterally spreading ground. Uncertainties in structural and geotechnical material properties as well as geometric parameters of the bridges are considered in finite element models to achieve comprehensive scenarios. The FO IMs considered include peak ground response (PGR α ), cumulative absolute response (CAR α ) and its modified version (CAR 5α ), spectral acceleration at 2.0 s for a fractionally damped single degree of freedom (SDF) system (S ad-20α ) and for a conventional SDF system with fractional response (S ar-20α ), spectrum intensity for a fractionally damped SDF system (SI dα ), as well as for a conventional SDF system with fractional response (SI rα ). Metrics such as efficiency, practicality, proficiency and sufficiency are measured to assess the optimal α with respect to different demand parameters. Results show the advantages of FO IMs as they increase confidence in demand models compared to traditional integer order IMs. In particular, the proposed fractional spectrum intensities (SI dα and SI rα ) with their optimal α values produce significant improvements in practicality, efficiency and proficiency, while maintaining sufficiency. Therefore, FO IMs can provide more reliable demand models for probabilistic seismic demand analysis of extended pile-shaft supported bridges in liquefiable and laterally spreading ground. © 2019 Elsevier Ltd","Bridges; Extended pile shafts; Fractional order calculus; Liquefaction-induced lateral spreading; Seismic demand models; Seismic intensity measures","Bridges; Calculations; Degrees of freedom (mechanics); Earthquake effects; Earthquake engineering; Efficiency; Spectrometry; Fractional-order calculus; Lateral spreading; Pile shaft; Seismic demand models; Seismic intensity measures; Piles; bridge; earthquake intensity; finite element method; ground motion; liquefaction; modeling; pile; seismic response",,,,,"National Science Foundation, NSF: CMMI-1462177, CMMI-1462183; National Natural Science Foundation of China, NSFC: 51278375, 51778469; China Postdoctoral Science Foundation: 2018M640448","This study is supported by National Science Foundation of the United States ( CMMI-1462177 and CMMI-1462183 ), National Natural Science Foundation of China ( 51278375 and 51778469 ) and China Postdoctoral Science Foundation ( 2018M640448 ).

This is the main reason of the length limitation of railway bridge and an increase in the construction cost. Also, the track-bridge interaction analysis should be performed in order to examine the influence of track-bridge interaction. Several standards specifies analysis methods and limit values for TBI to guarantee the safety design of railway track. However, the interaction effects are not fully understood yet due to the uncertainty of ballasted track. Thus, the interaction effects should be investigated and verified based on the field test results. In this paper, the measurement and analysis method for the track-bridge interaction was proposed. For this, the measurement system was developed considering the parameters causing the track-bridge interaction, and the track-bridge interaction response caused by temperature change was measured and analyzed. From the results, the track-bridge interaction phenomenon can be fully analyzed and quantified through the measurement system presented in this study.

It is required to inspect fracture-critical bridges using “arms-length” approach, which is costly and time consuming. Structural health monitoring can be used as alternative approach for inspection providing both accuracy and economy. This paper investigates the feasibility of using a handful of self-powered wireless sensors for continuous monitoring and detection of fracture in steel plate girder bridges. A detailed finite element analysis was carried out on a multi-girder bridge using available traffic data. The time histories of displacement obtained for intact and fractured scenarios show that vibration amplitude was significantly increased for fractured girder, and strain variation was recorded especially in the vicinity of fracture, conditions that can be detected with relevant sensors. Moreover, the amplitude and frequency of the vibration was significant enough to provide the required power for typical sensor(s). © 2019 Taylor & Francis Group, London, UK.","Bridges; Damage Detection; Fracture Critical; Health Monitoring; Self-powered Sensor; Steel Girder","Bridges; Damage detection; Plate girder bridges; Railroad bridges; Steel beams and girders; Structural health monitoring; Continuous monitoring; Fracture-critical bridges; Health monitoring; Multi-girder bridges; Self-powered; Steel girder; Steel plate girders; Vibration amplitude; Fracture",,,,,,,,,,,,,,,,"(2017) AASHTO LRFD Bridge Design Specifications.

The generated third-harmonic component is used to achieve the brushless operation in a wound field synchronous machine (WFSM). Contrary to the traditional schemes used, i.e., dual inverter, single inverter with extra switches schemes, and single inverter with four transistor legs, the proposed scheme comprises a single inverter with three transistor legs that utilizes a modified third-harmonic injection pulse-width modulation. The brushless operation in WFSM requires two windings on the rotor periphery, i.e., harmonic winding and field winding that are interconnected through a rotating diode bridge rectifier. To maximize the usage of generated third-harmonic component, the selection of pole–slot combinations of the machine is carried out considering the winding factors. The proposed inverter scheme is verified in MATLAB, and a 2-D finite element analysis is used to validate the brushless operation of the machine along with its electromagnetic performance. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.","Brushless wound field synchronous machine (BL-WFSM); Harmonic winding; THI-PWM inverter; Third-harmonic magnetomotive force (MMF) component; Winding factor","Bridge circuits; Electric inverters; Harmonic analysis; Pulse width modulation; Rotors (windings); Voltage control; Winding; 2D finite element analysis; Diode bridge rectifiers; Electromagnetic performance; Field-synchronous machines; PWM inverter; Third harmonic; Third harmonic components; Winding factors; Synchronous machinery",,,,,,,,,,,,,,,,"Zhao, W., Xing, F., Wang, X., Lipo, T.A., Kwon, B.I., Design and analysis of a novel PM-assisted synchronous reluctance machine with axially integrated magnets by the finite-element method (2017) IEEE Trans Magn, 53 (6), pp. 1-4; Barcaro, M., Bianchi, N., Interior PM machines using ferrite to replace rare-earth surface PM machines (2014) IEEE Trans Ind Appl, 50 (2), pp. 979-985; Lipo, T.A., Du, Z.S., Synchronous motor drives-a forgotten option (2015) 2015 International Aegean Conference on Electrical Machines & Power Electronics (ACEMP), 2015 International Conference on Optimization of Electrical & Electronic Equipment (OPTIM) & 2015 International Symposium on Advanced Electromechanical Motion Systems (ELECTROMOTION), Side, 2015, pp. 1-5; Bash, M.L., Pekarek, S., Analysis and validation of a population-based design of a wound-rotor synchronous machine (2012) IEEE Trans Energy Convers, 27 (3), pp. 603-614; Laldin, O., Sudhoff, S.D., Pekarek, S., An analytical design model for wound rotor synchronous machines (2015) IEEE Trans Energy Convers, 30 (4), pp. 1299-1309; Chai, W., Zhao, W., Kwon, B.I., Optimal design of wound field synchronous reluctance machines to improve torque by increasing the saliency ratio (2017) IEEE Trans Magn, 53 (11), pp. 1-4; Inoue, K., Yamashita, H., Nakamae, E., Fujikawa, T., A brushless self-exciting three-phase synchronous generator utilizing the 5th-space harmonic component of magneto motive force through armature currents (1992) IEEE Trans Energy Convers, 7 (3), pp. 517-524; Hussain, A., Kwon, B., A new brushless wound rotor synchronous machine using a special stator winding arrangement (2018) Electr Eng, 100, p. 1797; Yao, F., An, Q., Sun, L., Lipo, T.A., Performance investigation of a brushless synchronous machine with additional harmonic field windings (2016) IEEE Trans Industr Electron, 63 (11), pp. 6756-6766; Yao, F., An, Q., Sun, L., Illindala, M.S., Lipo, T.A., Optimization design of stator harmonic windings in brushless synchronous machine excited with double-harmonic-windings (2017) 2017 International Energy and Sustainability Conference (IESC), pp. 1-6. , Farmingdale, NY; Qasim, A., Lipo, T.A., Kwon, B., Design and analysis of a novel brushless wound rotor synchronous machine (2015) IEEE Trans Magn, 51 (11); Jawad, G., Ali, Q., Lipo, T.A., Kwon, B.I., Novel brushless wound rotor synchronous machine with zero-sequence third-harmonic field excitation (2016) IEEE Trans Magn, 52 (7), pp. 1-4; Yao, F., An, Q., Gao, X., Sun, L., Lipo, T.A., Principle of operation and performance of a synchronous machine employing a new harmonic excitation scheme (2015) IEEE Trans Ind Appl, 51 (5), pp. 3890-3898; Houldsworth, J.A., Grant, D.A., The use of harmonic distortion to increase the output voltage of a three-phase PWM inverter (1984) IEEE Trans Ind Appl, 1 (5), pp. 1224-1228; Jose, J., Goyal, G.N., Aware, M.V., Improved inverter utilisation using third harmonic injection (2010) 2010 Joint International Conference on Power Electronics, Drives and Energy Systems & 2010 Power India, pp. 1-6. , New Delhi; Perales, M.A., Prats, M.M., Portillo, R., Mora, J.L., Franquelo, L.G., Three-dimensional space vector modulation for four-leg inverters using natural coordinates (2004) 2004 IEEE International Symposium on Industrial Electronics, 3, pp. 1129-1134; Ribeiro, R.L.A., Jacobina, C.B., Lima, A.M.N., da Silva, E.R.C., A strategy for improving reliability of motor drive systems using a four-leg three-phase converter (2001) APEC 2001.

Combining materials with different mechanical properties make composites more difficult to evaluate where the damage mechanisms for composites are more complex than traditional materials such as steel. A relatively new non-destructive testing (NDT) method known as the electromechanical impedance (EMI) technique has been studied by various researchers, but the damage detection performance of the method on composite structures still requires more investigations before it can be accepted for field application, especially in aerospace industry due to the high standard of safety. In this paper, the detection capabilities and performance of the EMI technique subjected to different PZT attachment methods have been investigated. To this end, glass fibre composite plates with various attachment methods for the sensor have been prepared and detection of common defects such as delamination and crack with the EMI technique under study has been performed. The performance of each attachment method for identifying different damage types has been analysed and finite element analysis (FEA) was carried out for verification of the experimental results. © 2019 by the authors.

To provide good crashworthiness and performance, an energy absorption structure consisted of thin-wall ‘U’ shape steel and filled composite honeycomb tubes was adopted. The present paper aims to assess the dynamical performance and energy absorption capacity of the designed protection structure under various vehicles collision for its application, in which the Ford Taurus, Chevrolet pickup and truck provided by NACA (National Crash Analysis Centre) are adopted in the numerical simulations. For obtaining reliable results, the FE (finite element) model of energy absorption structure and actual vehicles are separately calibrated by experimental results. Based on the validated FE modelling technology, the dynamical response and performance of the designed protection structure are investigated considering various influential parameters, including impact velocities, angles, and types of vehicle. © 2020 Elsevier Ltd","Bridge; Collision; Composite material; Finite element method; Vehicle","Accidents; Bridges; Crashworthiness; Energy absorption; Honeycomb structures; Piers; Dynamic performance; Dynamical performance; Dynamical response; Energy absorption capacity; Energy absorption structure; Honeycomb composite; Protection structure; Vehicles collision; Vehicle performance",,,,,"National Natural Science Foundation of China, NSFC: 51609192, 51679100; Fundamental Research Funds for the Central Universities: 2017IVB007, 2018KFYYXJJ014; Fundamental Research Funds for Central Universities of the Central South University","This work has been supported by the Natural Science Fund of China (Grant No. 51609192 , 51679100 ), the Fundamental Research Funds for the Central University ( 2017IVB007 , 2018KFYYXJJ014 ).","This work has been supported by the Natural Science Fund of China (Grant No. 51609192, 51679100), the Fundamental Research Funds for the Central University (2017IVB007, 2018KFYYXJJ014).",,,,,,,,,"Monique, C.H., Evaluation of the performance of bridge steel pedestals under low seismic loads [D] (2007), Doctor Thesis of Georgia Institute of Technology; Wardhana, K., Hadiprione, F.C., Analysis of recent bridge failures in the United States (2003) J.

RC thermal models derived from the well-known methods have some ability to predict the temperature. However, the accuracy is boundary condition specific; hence, these methods cannot be used in the reliability analysis. To make the thermal model more accurate and robust, the factors contributing to discrepancies need to be analyzed carefully. These are power-module-materials' nonlinear properties, thermal grease layer, and the cooling system (i.e., liquid-cooled cold plate). In this article, the estimation of accurate RC parameters from the FEA thermal model is demonstrated in COMSOL. The electrical model having temperature-dependent power loss model is coupled to a refined thermal model and solved in a circuit simulator, PLECS. The proposed method is applied in two applications: assessing thermal interaction between IGBTs and antiparallel diodes in a half-bridge power module and assessing thermal interaction among the discrete switches in an interleaved bidirectional dc-dc converter. Results show that the impact of material nonlinearity, thermal grease layer, and cooling boundary conditions are significant for accurate prediction of IGBT and diode temperatures. The proposed model is consistent with FEA results and differs by 2%-6.5% compared with the experimental results. © 1986-2012 IEEE.","Circuit simulator; Dc-dc converter; Electrothermal model; Finite-element analysis (FEA); IGBT power module","Boundary conditions; Circuit simulation; Forecasting; Insulated gate bipolar transistors (IGBT); Reliability analysis; Semiconductor diodes; Thermography (temperature measurement); Accurate prediction; Anti-parallel diodes; Bidirectional DC-DC converters; Electrical modeling; Material non-linearity; Nonlinear properties; Power electronics converters; Temperature dependent; DC-DC converters",,,,,"University of Greenwich; Engineering and Physical Sciences Research Council, EPSRC: EP/K034804/1","Manuscript received July 8, 2018; revised November 25, 2019; accepted January 11, 2020.

But with the dimension of the potential parameters during optimization increasing, it brings a challenge to present optimization methods. To improve the performance of convergence process and the probability of detecting global extremum, a combination model updating method of modified particle swarm optimization (MPSO) and response surface method was proposed herein. MPSO has less modification to PSO as only modifying the particle position with Gaussian white noise at a probability and the performance was significantly superior than PSO illustrated by testing functions. A beam model updating example based on the proposed method was tested, the convergence ability and accuracy were compared with genetic algorithm which is widely applied in bridge model updating. Finally, the proposed method was successfully applied to model updating of an existing bridge engineering structures with thirteen variables. © 2020 Elsevier Ltd","Existing bridge structure; Finite element model updating; Gaussian white noise; High dimensional parameter; Modified particle swarm optimization; Vibration excitation test","Finite element method; Gaussian noise (electronic); Genetic algorithms; Railroad bridges; White noise; Existing bridge; Finite-element model updating; Gaussian white noise; High-dimensional; Modified particle swarm optimization; Vibration excitation; Particle swarm optimization (PSO)",,,,,"National Natural Science Foundation of China, NSFC: 51438002; Suzhou University of Science and Technology: XKQ2018008; Natural Science Research of Jiangsu Higher Education Institutions of China: 19KJB560020, 19KJB560021; Fundamental Research Funds for the Central Universities: 30919011246; Priority Academic Program Development of Jiangsu Higher Education Institutions, PAPD; ZD1803","This study was jointly supported by National Natural Science Foundation of China (Grant No. 51438002), the research fund of Jiangsu Province Key Laboratory of Structure Engineering, China (Grant No. ZD1803), Natural Science Foundation of Suzhou University of Science and Technology (Grant No. XKQ2018008), the Fundamental Research Funds for the Central Universities (Grant No. 30919011246), Natural Science Foundation of Jiangsu Higher Education Institutions of China (Grant Nos. 19KJB560021 and 19KJB560020) and a Project Funded by the Priority Academic Program Development of Jiangsu Higher Education Institutions.","This study was jointly supported by National Natural Science Foundation of China (Grant No. 51438002 ), the research fund of Jiangsu Province Key Laboratory of Structure Engineering, China (Grant No. ZD1803 ), Natural Science Foundation of Suzhou University of Science and Technology (Grant No. XKQ2018008 ), the Fundamental Research Funds for the Central Universities (Grant No. 30919011246 ), Natural Science Foundation of Jiangsu Higher Education Institutions of China (Grant Nos. 19KJB560021 and 19KJB560020 ) and a Project Funded by the Priority Academic Program Development of Jiangsu Higher Education Institutions .",,,,,,,,,"Mashayekhi, M., Santini-Bell, E., Three-dimensional multiscale finite element models for in-service performance assessment of bridges (2019) Comput.-Aided.

In this study, experimental and numerical approaches were combined to investigate the dynamic properties of a steel–UHPC composite deck. A large-scale steel–UHPC composite deck specimen was fabricated and tested under hammer impacting. The effects of the impact force characteristics on structural vibrations and noise were evaluated, and the vibration transmission characteristics in the deck were explored. The experimental results revealed that the steel–UHPC composite deck with large U-ribs exhibited complicated dynamic properties in different frequency bands. A finite element (FE) model was built and validated through comparison with the experimental natural frequencies and frequency responses. FE analysis was then used to compare the steel–UHPC composite deck with two other bridge deck systems (a conventional orthotropic steel deck and a steel–concrete composite deck). The numerical results indicated that the thin UHPC layer guaranteed the stiffness of the steel deck plate in the low-frequency range. At frequencies above 200 Hz, the vibration energy of the conventional orthotropic steel deck was approximately 0.45 times that of the steel–UHPC composite deck. Two countermeasures for reducing vibration (i.e., adjusting the crossbeam spacing and filling the large U-ribs with plain concrete) were found to be effective. Based on the simulation results, filling the U-ribs with plain concrete was the most effective approach and reduced the vibration energy by an average of 285% in the center frequency range of 63–1600 Hz. © 2020 Elsevier Ltd","Dynamic properties; Finite element analysis; Large U-ribs; Model validation; Steel–UHPC composite deck","Bridge decks; Finite element method; Frequency response; Structural dynamics; Composite decks; Dynamic property; Large U-ribs; Model validation; Orthotropic steel decks; Structural vibrations; Ultra high performance concretes (UHPC); Vibration transmission; High performance concrete; composite; dynamic property; experimental study; finite element method; numerical model; reinforced concrete; steel structure; vibration",,,,,"National Natural Science Foundation of China, NSFC: 51778534, 51978580; Ministry of Science and Technology of the People's Republic of China, MOST: KY201801005; Southwest Jiaotong University, SWJTU","This study was supported by the National Natural Science Foundation of China [grant Nos. 51778534 and 51978580] and the Ministry of Science and Technology of China [grant No. KY201801005].

A three-dimensional nonlinear finite element model, developed in computer program ANSYS, is utilized to analyze the response of prestressed concrete box bridge girders under combined effects of fire exposure duration and simultaneous structural loading. The model validation is performed using a scaled prestressed concrete box girder exposed to ISO834 fire in furnace. Subsequently, the validated model is used to investigate fire performance of prestressed concrete box bridge girders through taking into consideration some variables, namely concrete cover thickness to prestressing strands, prestress degree, load level, fire exposure length, and position. Through a case study, results from numerical analysis show that concrete cover thickness to prestressing strands and load level has significant effect on fire resistance of prestressed concrete box bridge girders. Increasing prestress degree in prestressing strands can speed up the progression of deflection (sudden collapse) in prestressed concrete box bridge girder toward the final fire exposure stage. Reducing fire exposure length or preventing fire exposure on mid-span zone can highly enhance the fire resistance of simply supported prestressed concrete box bridge girders. Failure of prestressed concrete box bridge girder, under hydrocarbon fire exposure conditions, is governed by rate of deflection failure criterion in particular cases. © The Author(s) 2020.","bridge fires; failure criterion; finite element analysis; fire resistance; prestressed concrete box bridge girders","Box girder bridges; Composite beams and girders; Concrete beams and girders; Finite element method; Fire resistance; Highway bridges; Hydrocarbons; Plate girder bridges; Prestressed beams and girders; Prestressed concrete; Prestressing; Bridge girder; Concrete cover thickness; Failure criteria; Model validation; Prestressed concrete box girder; Prestressing strands; Structural loading; Three-dimensional nonlinear finite element model; Failure (mechanical)",,,,,"JKKJ-2018-14; Michigan State University, MSU; National Natural Science Foundation of China, NSFC: 51878057; Ministry of Transport of the People's Republic of China, MOT: 2011318812970; Natural Science Basic Research Program of Shaanxi Province: 2018JM5018","The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: The research described in this paper was financially supported by Ministry of Transport of the People’s Republic of China (Grant No. 2011318812970), Natural Science Foundation of China (Grant No. 51878057), National Science Basic Research Plan in Shaanxi Province of China (Grant No. 2018JM5018) and Technology Project in Anhui Transportation Holding Group (Grant No. JKKJ-2018-14), and Michigan State University.

Considering this attribute of open-winding patterns, a harmonic current field excitation technique for a wound rotor synchronous machine (WRSM) is proposed in this paper based on the control of time-harmonic magneto-motive force. Two inverters connected to both terminals of the stator winding are controlled so that the input armature current generates an additional third-harmonic current component. This third-harmonic component generates a vibrating magnetic field that induces a current in the specially designed rotor harmonic winding. The current is supplied as DC current to the rotor excitation winding to generate a rotor field by using a full-bridge diode rectifier in order to achieve brushless operation. The proposed dual-inverter-controlled brushless operation for a WRSM is executed in ANSYS Maxwell using 2-D finite element analysis to validate its operation and electromagnetic performance. © 2020 by the authors.","Brushless operation; Open-winding pattern; Third-harmonic MMF; Wound rotor synchronous machines","Electric inverters; Electric rectifiers; Harmonic analysis; Rotors (windings); Stators; Synchronous machinery; Winding; 2D finite element analysis; Armature currents; Electromagnetic performance; Harmonic currents; Open-winding machine; Third harmonic components; Three phase stator; Wound rotor synchronous machines; Electric machine control",,,,,"Ministry of Education, MOE: 2016R1D1A1B01008058; Ministry of Trade, Industry and Energy, MOTIE; Ministry of Science, ICT and Future Planning, MSIP: 2019H1D3A1A01102988; National Research Foundation of Korea, NRF; Korea Institute of Energy Technology Evaluation and Planning, KETEP; Ministry of Education and Human Resources Development, MOEHRD: 20184030202070","Funding: This research was supported in part by the National Research Foundation of Korea funded by the Ministry of Education (2016R1D1A1B01008058), Human Resources Development (No.20184030202070) of the Korea Institute of Energy Technology Evaluation and Planning (KETEP) grant funded by the Korea government Ministry of Trade, Industry and Energy, and by the Korea Research Fellowship Program through the National Research Foundation (NRF) of Korea funded by the Ministry of Science and ICT (2019H1D3A1A01102988).",,,,,,,,,,"Sun, L., Gao, X., Yao, F., An, Q., Lipo, T., A new type of harmonic current excited brushless synchronous machine based on an open winding pattern (2014) Proceedings of the 2014 IEEE Energy Conversion Congress and Exposition (ECCE), pp. 2366-2373. , Pittsburgh, PA, USA, 14-18 September; Yao, F., Sun, D., Sun, L., Lipo, T.A., Dual third-harmonic-current excitation principle of a brushless synchronous machine based on double three-phase armature windings (2019) Proceedings of the 2019 22nd International Conference on Electrical Machines and Systems (ICEMS), pp. 1-4. , Harbin, China, 11-14 August; Di Gioia, A., Brown, I.P., Nie, Y., Knippel, R., Ludois, D.C., Dai, J., Hagen, S., Alteheld, C., Design and demonstration of awound field synchronous machine for electric vehicle traction with brushless capacitive field excitation (2018) IEEE Trans.

The seismic performance of this new steel bridge column was investigated experimentally on eight unique steel-box pier samples with varying geometric and material features under vertical eccentric and horizontal cyclic loads. The experimental results were compared with numerical simulation results to validate the accuracy of the finite element method. The effects of fan-shaped stiffener spacing, eccentricity of vertical loading, ratio of axial compression, thickness of embedded shell, ratio of slenderness, and material strength of embedded shell plates and box wall plates on the seismic behaviour of the new steel-box bridge-piers are discussed. Results showed that installation of embedded energy-dissipating shell plates improved the ductility and strength capacity of the new type of steel bridge piers. The recommended fan-shaped stiffener spacing was one-third to half of the box cross-sectional dimension. If the spacing of the fan-shaped stiffeners is extremely small, the deformation of the embedded energy-consuming shells will be limited, resulting in a small fracture displacement of the specimen, accelerated stiffness degradation, and reduced deformation capacity and ductility. The eccentricity of the vertical loading results in asymmetrical skeleton curves. The decrease in axial compression ratio or the increase in embedded shell thickness can lead to a higher ultimate capacity and smoother post-yield hysteretic curve for the specimens, thereby affording better seismic performances. The increase in slenderness ratio can engender a reduced initial stiffness, ultimate load, and envelope area of the hysteresis loop for the specimen, thereby yielding a worse seismic performance. The increase in material strength in the box wall plates or embedded shell plates can yield a larger ultimate displacement and smaller stiffness degradation for the specimen, thereby suggesting an enhanced energy-consumption capacity and improved seismic performance for this new type of box bridge pier. © 2020, Springer Nature B.V.","Eccentric compression; Quasi-static test; Seismic behaviour; Steel-box bridge-pier column","Axial compression; Bridge piers; Columns (structural); Deformation; Ductility; Energy utilization; Hysteresis; Numerical methods; Seismic waves; Seismology; Steel bridges; Stiffness; Strength of materials; Deformation capacity; Eccentric compression; Fracture displacement; Quasi-static tests; Ratio of slenderness; Seismic behaviour; Steel box; Stiffness degradation; Shells (structures); compression; displacement; ductility; eccentricity; energy dissipation; fracture geometry; pier; seismic hazard; seismic response; spacing; steel structure; stiffness",,,,,"University of New South Wales, UNSW: 201807540009; National Natural Science Foundation of China, NSFC: 51778248; Natural Science Foundation of Fujian Province: 2018J01075; Huaqiao University, HQU: ZQN-PY312; China Scholarship Council, CSC; Guangxi Key Laboratory of Disaster Prevention and Engineering Safety","This research work was supported by National Natural Science Foundation of China (No. 51778248), Natural Science Foundation of Fujian Province (No. 2018J01075), Promotion Program for Young and Middle-aged Teacher in Science and Technology Research of Huaqiao University (No. ZQN-PY312), and Research Trained Fund for Outstanding Young Researcher in Higher Education Institutions of Fujian Province.

Information on displacement is particularly important for bridge state estimation, but it is difficult to measure. To obtain the required data at any position, a hybrid monitoring (HM) algorithm that combines the finite-element model (FEM) with the monitored data is proposed to extend these data from discrete points to the full structure. The aim of this study is to demonstrate the accuracy and adaptiveness of the algorithm by adopting a complex, large-scale bridge model and considering the modeling error and environmental noise. First, the basic idea and theoretical basis of HM is briefly introduced, and a multitype data-fusion method is proposed to improve the accuracy. Then the experimental equipment, FEM, and updating process are introduced. The influences of the global stiffness error and the boundary condition error are subsequently discussed, showing the algorithm robustness. Finally, the experimental results from two quasi-dynamic loading conditions confirm the HM accuracy using different data sources with high computational efficiency. The superiority of the HM method is also validated by comparing it with some existing methods. © 2020 American Society of Civil Engineers.","Deflection estimation; Hybrid monitoring; Inclination; Partial least-square regression; Strain","Computational efficiency; Data fusion; Dynamic loads; Errors; Strain; Continuous bridges; Data fusion methods; Environmental noise; Experimental equipments; Inclination; Large-scale bridges; Partial least square regression; Structural health monitoring (SHM); Structural health monitoring",,,,,"National Natural Science Foundation of China, NSFC: 51878482; Tongji University: SLDRCE15-A-02; State Key Laboratory for Disaster Reduction in Civil Engineering","The authors acknowledge support for the work reported in this paper from the National Natural Science Foundation of China (Grant No. 51878482) and the State Key Laboratory of Disaster Reduction in Civil Engineering, Tongji University (Grant No. SLDRCE15-A-02).",,,,,,,,,,"Alkayem, N.F., Cao, M., Zhang, Y., Bayat, M., Su, Z., Structural damage detection using finite element model updating with evolutionary algorithms: A survey (2018) Neural Comput.

To investigate the potential of using rubberized concrete as anti-collision cladding of bridge piers, a set of static and dynamic tests and finite element modelling were carried out. First of all, normal concrete and rubberized concrete with different crumb rubber particle sizes and volume fractions were fabricated and tested to obtain its mechanical properties, including compressive strength, elastic modulus and loss factor. Then these mechanical properties were used in three truck-pier collision models established by LS-DYNA. The difference among the three models is the cladding of the pier. One was a single concrete pier without cladding (SP) and the other two were with normal concrete cladding (NC) and rubberized concrete cladding (RC). It is found that with the increase of rubber particle size and content, the compressive strength and elastic modulus decrease but the loss factor increases. Rubberized concrete cladding is suitable for protecting the bridge pier since its high energy dissipation capacity. © 2019","Finite element modelling; Loss factor; Rubberized concrete; Truck-pier collision","Bridge piers; Cladding (coating); Collision avoidance; Compressive strength; Concrete aggregates; Concrete testing; Elastic moduli; Energy dissipation; Finite element method; Particle size; Rubber; Trucks; Energy dissipation capacities; Finite element modelling; ITS applications; Loss factor; Normal concretes; Rubber particles; Rubberized concrete; Static and dynamic tests; Concretes",,,,,"National Natural Science Foundation of China, NSFC: 51478030","The research is funded by National Science Foundation of China (grant no. 51478030 ).",,,,,,,,,,"Hassanli, R., Youssf, O., Mills, J.E., Seismic performance of precast posttensioned segmental FRP-confined and unconfined crumb rubber concrete columns (2017) J.

The study is divided into experiments on RC rectangular beams and scaled (1:12) T-beams, validation of numerical models for T-beams and training of corresponding artificial neural networks (ANNs). In the experimental work, Digital Image Correlation (DIC) was used as a virtual sensor for data extraction. Rectangular RC beams of size 1800 mm × 150 mm × 200 mm and scaled (1:12) RC T-beams were tested under four-point flexural loading on a 100-ton dynamic testing machine. The experimental stress-strain curves obtained from the compression test on prism specimens at 28 days were used as input data for material model parameters in finite element model (FEM) software SAP2000. To assess the condition of structural components, a local damage index (LDI) was developed. Validation of FEM results with experimental results enables derivation of moment-curvature backbone curve for full-scale bridge girders, which enables further quantification of damage and residual moment capacity of full-scale bridges designed by Ministry of Road Transport and Highways (MoRTH).

A finite element analysis was performed to verify the power increase mechanism of the ACBEH. The simulation model of the ACBEH comprises of three main components: Support, tip mass, and cantilever beam with a re-entrant hexagonal auxetic structure in which a piezoelectric element bonded to top of the auxetic region by using a thin elastic layer of epoxy. The performance of the ACBEH was computationally investigated and compared with an equivalent conventional energy harvester with a plain cantilever beam where they are attached to a bridge stay cable. The simulation result shows that the ACBEH excited by a harmonic acceleration of 1 m/s2 at 3 Hz is able to produce electric power of 427.22 μW, which is 2.51 times that of the power produced by the equivalent plain cantilever beam energy harvester (170.17 μW). This paper opens up a great potential of using auxetic cantilever beam applications for different energy harvesting systems in Metamaterials, Acoustics, Civil, Electrical, Aerospace, Biomedical, and Mechanical Engineering. © 2020 SPIE.","Auxetic cantilever beam; Cable-stayed bridge; Energy harvesting; Self-powered structural health monitoring; Smart bridge monitoring; Wireless sensor network","Cantilever beams; Energy harvesting; Industry 4.0; Smart city; Ambient vibrations; Auxetic structures; Bridge stay cables; Energy Harvester; Energy harvesting systems; Piezoelectric elements; Simulation model; Thin elastic layer; Nanocantilevers",,,,,,,,,,,,,,,,"HekmatiAthar, S., Taheri, M., Secrist, J., Taheri, H., Neural network for structural health monitoring with combined direct and indirect methods (2020) Journal of Applied Remote Sensing, 14 (1), p. 014511; Hasanian, M., Choi, S., Lissenden, C., Laser ultra sonics toward remote detection of stress corrosion cracking (2019) Materials Evaluation, 77 (9), pp. 1089-1098; Farhangdoust, S., Mehrabi, A., Non-destructive evaluation of closure joints in accelerated bridge construction using a damage etiology approach (2020) Applied Sciences, 10 (4), p. 1457; Farhangdoust, S., Mehrabi, A., Health monitoring of closure joints in accelerated bridge construction: A review of non-destructive testing application (2019) Journal of Advanced Concrete Technology, 17 (7), pp. 381-404; Cho, H., Hasanian, M., Shan, S., Lissenden, C.J., Nonlinear guided wave technique for localized damage detection in plates with surface-bonded sensors to receive Lamb waves generated by shear-horizontal wave mixing (2019) NDT & E International, 102, pp. 35-46; Hasanian, M., Choi, S., Lissenden, C., Laser ultrasonics toward remote detection of stress corrosion cracking (2019) Materials Evaluation, 77 (9), pp. 1089-1098; Farhangdoust, S., Mehrabi, A., NDT inspection of critical ABC details to assure life cycle performance and avoid future unforeseen excessive repairs (2019) Structures Congress 2019American Society of Civil Engineers, , April; Lee, J.L., Tyan, Y.Y., Wen, M.H., Wu, Y.W., Development of an iot-based bridge safety monitoring system (2017) 2017 International Conference on Applied System Innovation (ICASI), pp. 84-86. , (May). .

Severe Joule heating and current crowding effects on actual temperature, shear strength, damage and fracture behavior of the joints under coupled electromechanical loads were studied by theoretical formulation and experimental characterization, as well as finite element simulation. Results demonstrate that severe Joule heating and current crowding effects lead to significantly increased temperature in the joints, which is much higher than the ambient temperature. The shear strength of joints under coupled electromechanical loads shows strong dependence on current density, in terms of a relatively rapid monotonic decrease with the increasing current density. Moreover, a fully coupled finite element model was developed to characterize the degree of damage of joints under coupled electro-mechanical loads. The results show that electric current leads to aggravated damage in the joints, and damage occurs and accumulates much more easily in joints subjected to high density current stressing. The maximum viscoplastic dissipation energy density increases monotonically with current density. With increasing current density, there is a transition in fracture position (path) from the solder matrix to the solder/IMC interface of the joints, which corresponds to a shift in fracture mode from ductile fracture to brittle fracture. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.",,"Ball grid arrays; Bridge decks; Current density; Ductile fracture; Finite element method; Fracture mechanics; Joule heating; Current crowding effect; Electromechanical loads; Experimental characterization; Finite element simulations; Increased temperature; Shear strength of joint; Theoretical formulation; Viscoplastic dissipation; Shear flow",,,,,"201807010028; National Natural Science Foundation of China, NSFC: 51405162, 51775195; Science and Technology Planning Project of Guangdong Province: 2016A010103010","This research is supported by the National Natural Science Foundation of China under grant Nos. 51775195 and 51405162, the Science and Technology Planning Project of Guangdong Province under Grant Nos. 2016A010103010, and the Key Project of Guangzhou City Science and Technology Plan under Grant No. 201807010028.",,,,,,,,,,"Nah, J.W., Suh, J.O., Tu, K.N., (2005) J.

The fatigue reliability of a bridge is a function of the fatigue damage accumulation; a stochastic fatigue damage model (SFDM) with physical mechanism is introduced for deriving the fatigue damage process. In order to implement the probabilistic analysis, based on the probability density evolution method (PDEM), the generalised density evolution equation (GDEE) for the remaining fatigue life is developed. Finally, a prestressed concrete continuous beam bridge located in China is illustrated. The random fatigue load acting on the bridge is modelled as the compound Poisson process, and the simulation of the random load uses the stochastic harmonic function (SHF) method. To simplify the reliability analysis, an equivalent constant-amplitude (ECA) load process is introduced based on energy equivalence. By employing SFDM, the finite element analysis of the bridge under the fatigue loading is performed. Then, the fatigue damage accumulation process of the bridge under the fatigue loading is obtained. Through solving the probability density evolution equation for the remaining fatigue life, the probability density functions (PDFs) of the remaining fatigue life evolving with time is obtained. The fatigue reliability is then calculated by integrating the PDF of the corresponding remaining life. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.","concrete bridges; Fatigue reliability; probability density evolution method; stochastic fatigue damage model","Concrete bridges; Differential equations; Harmonic functions; Prestressed concrete; Probability density function; Random processes; Reliability analysis; Stochastic models; Stochastic systems; Compound Poisson process; Fatigue damage accumulation; Fatigue reliability; Probability density evolution equation; Probability density evolution method; Probability density evolution methods (PDEM); Probability density functions (PDFs); Stochastic fatigue damages; Fatigue damage",,,,,"University of California, Irvine, UCI; National Natural Science Foundation of China, NSFC: 51261120374, 51538010; Tongji University","This study was performed at the University of California, Irvine during the one-year that Ms Ruofan Gao spent as Visiting Scholar performing her doctoral dissertation for her Ph.D. degree at the Tongji University in Shanghai, China.

In this perspective, a novel computational approach is here proposed for both real-time and off-line parameter identification (PI). The system response is governed by a set of four partial differential equations (PDE) where the three displacement components and the electrical potential are the unknowns. Firstly, the finite element (FE) method is used to reduce the PDE problem into a set of ordinary differential equations (ODE). Then, a state-space model is derived with the aim to limit the PI problem to a subset of unknowns. After that, an identification error is introduced and the Lyapunov theory is used to derive the PI algorithm. The numerical implementation is based on a sensitivity analysis feedback block. The overall proposed computational strategy is robust and results in an exponential asymptotic convergence. The accuracy of the PI method is demonstrated by analysing the time-domain response of an array of piezoelectric bimorphs subjected to low-frequency structural random vibrations. The selected case-study is an existing cable-stayed bridge, for which an extensive dynamic monitoring campaign has provided the experimental data. Once time histories of the device response are obtained through time-dependent dynamic FE simulations, the PI algorithm is used to determine the unknown lumped coefficients of the state-space model. The comparison between FE method and lumped parameters model in terms of tip displacement and output voltage demonstrates the superior predictive capability of the new PI algorithm. As a result of the sensitivity analysis, guidelines to assess the optimal array configuration are also provided. © 2018 Elsevier Ltd","Energy harvesting; Finite element method; Parameter identification; Piezoelectric solid; Sensitivity analysis; State-space models","Cable stayed bridges; Computation theory; Energy harvesting; Identification (control systems); Ordinary differential equations; Parameter estimation; Piezoelectric devices; Piezoelectric materials; Piezoelectricity; Sensitivity analysis; State space methods; Structural health monitoring; Time domain analysis; Vibration analysis; Electromechanical systems; Lumped-parameters models; Numerical implementation; Ordinary differential equation (ODE); Partial differential equations (PDE); Piezoelectric solids; State - space models; Structural health monitoring (SHM); Finite element method",,,,,"Ministero dell’Istruzione, dell’Università e della Ricerca, MIUR: RBFR107AKG; Sapienza Università di Roma","Claudio Maruccio acknowledges the support from the Italian MIUR through the project FIRB Futuro in Ricerca 2010 Structural mechanics models for renewable energy applications (RBFR107AKG).

Two composite box bridge girders, a simply supported girder and a continuous girder respectively, were tested under simultaneous loading and fire exposure. The simply supported girder was exposed to fire over 40% of its span length in the middle zone, and the two-span continuous girder was exposed to fire over 38% of its length of the first span and full length of the second span. A measurement method based on comparative rate of deflection was provided to predict the failure time in the hogging moment zone of continuous composite box bridge girders under certain localized fire exposure condition. Parameters including transverse and longitudinal stiffeners and fire scenarios were introduced to investigate fire resistance of the composite box bridge girders. Test results show that failure of the simply supported girder is governed by the deflection limit state, whereas failure of the continuous girder occurs through bending buckling of the web and bottom slab in the hogging moment zone. Deflection based criterion may not be reliable in evaluating failure of continuous composite box bridge girder under certain fire exposure condition. The fire resistance (failure time) of the continuous girder is higher than that of the simply supported girder. Data from fire tests is successfully utilized to validate a finite element based numerical model for further investigating the response of composite box bridge girders exposed to localized fire. Results from numerical analysis show that fire resistance of composite box bridge girders can be highly influenced by the spacing of longitudinal stiffeners and fire severity. The continuous composite box bridge girder with closer longitudinal stiffeners has better fire resistance than the simply composite box bridge girder. It is concluded that the fire resistance of continuous composite box bridge girders can be significantly enhanced by preventing the hogging moment zone from exposure to fire. Longitudinal stiffeners with closer spacing can enhance fire resistance of composite box bridge girders. The increase of transverse stiffeners has no significant effect on fire resistance of composite box bridge girders.

The objective of the present paper is to apply the ultimate limit states as the structural design criteria of a box girder crane. For this purpose, a reference box girder crane structure which was originally designed and constructed based on the allowable working stress criteria and still in operation is selected. The structure is then redesigned applying the ultimate limit state criteria, where other types of limit states such as serviceability limit states and fatigue limit states are also considered. Nonlinear finite element method is applied to analyze the progressive collapse behaviour of the structure until and after the ultimate limit state is reached. While the ultimate strength or maximum load-carrying capacity of the structure has never been realized as far as the allowable working stress based design method is applied, this study starts with identifying it by the nonlinear finite element method. The structural weight was then attempted to minimize by changing structural member dimensions while the ultimate strength remains the same. It is concluded that the ultimate limit state based design method provides more economical, yet safe structures, compared with the allowable working stress based design method. Considerations for the serviceability limit states are addressed in the paper, while those for the fatigue limit states are presented in a separate article. © 2018","Allowable working stress; Box girder crane structures; Nonlinear finite element method; Serviceability limit states; Ultimate limit states","Box girder bridges; Cranes; Fatigue of materials; Finite element method; Structural dynamics; Structural loads; Crane structures; Fatigue limit state; Nonlinear finite element method; Progressive collapse; Serviceability limit state; Stress-based designs; Structural weight; Ultimate limit state; Occupational risks",,,,,,,,,,,,,,,,"Johansson, B., Velijkovic, M., Steel plated structures (2001) Progress.

To explore the strain behavior in the magnets, several cryogenic resistance strain gauges (CRSGs) and homemade polymer-fiber Bragg grating (FBG) sensors are used for measurements. The strain responses during excitation and quench training tests of the two LTS magnets are recorded to show that both measurement techniques have good precision and repeatability. Compared to the CRSG with complex compensation bridges, the polymer-FBG sensors exhibit more advantages like smaller size, noncircuit compensation, and insensitivity to electromagnetic interferences, and most important of all is that the polymer-FBG can be embedded in coils with good survival to measure the internal strain in the magnets. Based on FEM, we further calculated the electromagnetic field and deformation of the two magnets, and the predicted results show good agreement with the experimental data. © 2018 IEEE.","Cryogenic resistance strain gauge (CRSG); excitation and quench; fiber Bragg grating (FBG) sensor; strain response; superconducting magnet","Accelerator magnets; Bragg gratings; Cryogenics; Electromagnetic pulse; Fiber Bragg gratings; Fiber optic sensors; Polymers; Strain; Strain gages; Strain measurement; Superconducting coils; Temperature measurement; Temperature sensors; Deformation field; Fiber Bragg Grating Sensors; High field magnets; Internal strains; Measurement techniques; Mechanical characteristics; Resistance strain gauges; Strain response; Superconducting magnets",,,,,"National Natural Science Foundation of China, NSFC: 11327802, 11672120; China Postdoctoral Science Foundation: 2015T81071","Manuscript received March 13, 2018; revised August 9, 2018; accepted August 13, 2018.

However, there is neither unified standard nor complete evaluation system to evaluate the specific isolation effectiveness of FPB-isolated bridges with different pier heights. In this paper, the prototype bridge finite element models (FEM) of the typical simply supported girder bridges on the double-track railway in China, are established and studied. These bridge FEM differ in the pier height range of 4–60 m. Each FEM adopts two types of bearing: FPB (isolated bearing) and spherical steel bearing (non-isolated bearing). The nonlinear time history analysis is carried out to compare the seismic responses of FPB-isolated and non-isolated bridges. Based on the comparison results, the seismic isolation ratios of FPB are defined and obtained. In addition, a new criterion index is presented to quantifiably measure the effectiveness of the seismic isolation of FPB-isolated bridges with different pier heights, which is beneficial to the further popularization and application of FPB in the seismic design of bridge engineering. © 2020 Institution of Structural Engineers","Double-track railway; Friction pendulum bearing; Fuzzy logic control; Pier height; Seismic isolation ratio",,,,,,"National Natural Science Foundation of China, NSFC: 51778630, 51778635; Natural Science Foundation of Hunan Province: 2019JJ40386, KYY2018059; Department of Science and Technology of Sichuan Province, SPDST: 2019YFG0048","This research is jointly supported by the National Natural Science Foundations of China under grant No. 51778635 and 51778630, the Science and Technology Project of Sichuan Province under grant No. 2019YFG0048, the Natural Science Foundations of Hunan Province under grant No. 2019JJ40386, and the Research Program on Key Technology for the Seismic Design of Railway Bridge in Nine Degree Seismic Intensity Zone under grant No. KYY2018059.

Central to this study is the proposal of a simple static correlation formula for relating the dynamic deflections of the two vehicles's contact points on the bridge, via the displacement influence lines (DILs). With the aid of this relation, the roughness formula for estimating the bridge surface profile is derived using the responses of the leading and following vehicles. It does not require any prior knowledge of the dynamic properties of the bridge. The efficacy of the proposed procedure is validated for both the simple and three-span continuous beams by the finite element method (FEM). Also, a parametric study is conducted for various physical properties of the test vehicles. It is confirmed that the roughness profiles back-calculated from the proposed formula agree excellently with the assumed ones for both the simple and continuous beams. For use in practice, the two connected test vehicles should not be designed too heavy and not to move at too fast speeds, in order to reduce the impact on the bridge. © 2020 World Scientific Publishing Company.","contact point; displacement influence line; Roughness identification; vehicle response; vehicle scanning method","Automobile testing; Bridge decks; Vehicles; Bridge surfaces; Continuous beams; Correlation formulae; Dynamic deflections; Dynamic property; Following vehicle; Parametric study; Prior knowledge; Surface roughness",,,,,"cstc2019jcyj-bshX0115; K2019G036; National Natural Science Foundation of China, NSFC: 51678091","The senior author likes to thank the Fengtay Foundation for endowment of the Fengtay Chair Professorship.

However, little investigation has been carried out to indicate the influence of parameters affecting the mechanical properties of the bearings under large shear deformations (i.e., the seismic performance as an isolation system). A comparative parametric study was conducted herein through finite element modeling of SREBs. The implemented model was also verified by experimental test results. The hysteretic behavior was studied in both cases of bounded and unbounded, and under shear strains up to 125% of the bearing's total rubber height, which is far beyond that of service-load induced strains. Effects of critical parameters like shape factor, Shim thickness and vertical loading level were investigated. Meanwhile, the horizontal stiffness was kept constant to allow a rational comparative study. It was shown that shape factor and vertical load level have notable influence on the effective stiffness and equivalent viscous damping of the bearings. Ruptures were also seen in steel shims of both bounded and unbounded SREBs, which were categorized in flexural and slicing ruptures. Eventually, a bilinear model was derived from the finite element analyses results to predict the hysteretic behavior of SREBs, while considering the interactive effect of both shape factor and compressive stress. The proposed model can simply be implemented in macro modeling. © 2020 Institution of Structural Engineers","Base isolation; Bilinear model; Bounded; Bridge; Elastomeric bearing; Finite element modelling; Hysteretic behavior; Unbounded",,,,,,"529582; Sharif University of Technology","The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: This research was supported by Tehran Engineering and Technical Consulting Organization (TETCO).

In this paper, experimental and numerical investigation was conducted to study the degraded shear performance of reinforced concrete beam. The corrosion of reinforcements, crack patterns, and structural behaviors of corroded specimens with various corrosion levels accelerated by the impressed current method were analyzed. The test results indicated that the corrosion-induced crack patterns have a close relationship with the level of reinforcement corrosion. Moreover, an obvious degradation of shear performance of corroded RC beams in terms of initial stiffness, cracking loads, ultimate bearing capacity, post-peak behavior, and energy dissipation capacity was observed, which became more pronounced as the corrosion level increased. When a severe corrosion level (ηa ≥ 12%) was encountered, the failure mode could even be changed from the shear-compression failure into a much more brittle diagonal splitting failure. In parallel, to numerically simulate the propagation of the main diagonal crack faithfully, the extended finite element method (XFEM) specified with an exponential softening traction-separation relationship was adopted. Moreover, to investigate the effect of corrosion-induced bond degradation, a user-defined element (UEL) was also developed to represent the interfacial bond response. The reasonable agreement between the numerical simulation and experimental results proved the feasibility of the proposed approach. © 2020 Elsevier Ltd","Degradation; Reinforcement corrosion; Shear performance; UEL; XFEM","Bridge decks; Cathodic protection; Chlorine compounds; Concrete beams and girders; Crack propagation; Cracks; Degradation; Electrochemical corrosion; Energy dissipation; Failure (mechanical); Chloride induced corrosion; Corrosion of reinforcement; Energy dissipation capacities; Extended finite element method; Reinforced concrete beams; Reinforcement corrosion; Shear performance; XFEM; Reinforced concrete",,,,,"27204818; National Natural Science Foundation of China, NSFC: 51808475; National Basic Research Program of China (973 Program): 2015CB655103","The authors would like to thank the financial support from the Hong Kong Research Grants Council (Project number: 27204818 ), National Natural Science Foundation of China (Project number: 51808475 ), and National Basic Research Program (973 Program) (Project number: 2015CB655103 ).

The shape of permanent magnet (PM) shows great effect on cost, fabrication and magnetic flux density generation in the actuator. Axially magnetised disk shaped PMs are low cost and convenient for fabrication. Moreover, axially magnetised PMs generate high flux density in a specific direction compared to radial magnets. This paper investigates the design of axially magnetised moving magnet linear oscillating actuator (LOA) which operates on single phase alternating supply. Additionally, an alternative path is proposed for the return of magnetic flux from mover to the stator. Using finite element method (FEM) tools, all the parameters of LOA are optimised. Moreover, with the help of a specially designed experimental setup, FEM simulation results are validated. This actuator demonstrates great advancement in thrust force density, motor constant and output power compared to the size of proposed LOA. © The Institution of Engineering and Technology 2020.",,"Bridges; Finite element method; Linear actuators; Magnetic flux; Permanent magnets; Alternative path; FEM simulations; High flux density; Motor constant; Moving-magnet linear actuators; Oscillating actuators; Permanent magnets (pm); Thrust forces; Magnetic actuators",,,,,,,,,,,,,,,,"Bijanzad, A., Hassan, A., Lazoglu, I., 'Analysis of solenoid based linear compressor for household refrigerator' (2017) Int.

Reference is made to an Italian case study of a bridge pier to be founded on a well-characterized subsoil. Both a caisson and a 3×3 pile foundation are considered as suitable design options. For each foundation type, three different geometrical layouts satisfying Ultimate Limit State (ULS) checks are analysed. Equivalent-linear ground response analyses are preliminary performed to derive the mobilized soil stiffness and damping ratio. FE analyses of the complete soil-foundation-bridge pier model are then carried out. Results indicate that consideration of Soil-Structure Interaction effects strongly reduces the pier acceleration, especially for pile foundations, which allow for a higher dissipation of energy due to radiation damping. Further, the role of foundation type and layout is discussed by separating the kinematic and inertial components of interaction, with reference to both frequency and time domain response. Some considerations about possible simplifying assumptions to account for these effects in routine engineering are finally reported. © 2019 Elsevier Ltd","Bridge pier; Caisson foundation; Finite element modelling; Foundation impedances; Inertial interaction; Kinematic interaction; Pile foundation; Seismic performance; Soil-structure interaction","Bridge piers; Caissons; Damping; Kinematics; Pile foundations; Pressure vessels; Radiation effects; Seismic waves; Seismology; Soil structure interactions; Soils; Synchrotron radiation; Time domain analysis; Caisson foundations; Finite element modelling; Inertial interaction; Kinematic interaction; Seismic Performance; Piles; bridge; caisson; damping; finite element method; pile; seismic design; seismic response; soil-structure interaction; support structure",,,,,"Dipartimento della Protezione Civile, Presidenza del Consiglio dei Ministri, DPC","Part of this research was funded by the Department of Civil Protection through the ReLUIS (University Network of Seismic Engineering Laboratories) Consortium .",,,,,,,,,,"Gerolymos, N., Gazetas, G., Winkler model for lateral response of rigid caisson foundations in linear soil (2006) Soil Dyn Earthq Eng, 26 (5), pp. 347-361; Karapiperis, K., Gerolymos, N., Combined loading of caisson foundations in cohesive soil: finite element versus Winkler modeling (2014) Comput Geotech, 56, pp. 100-120; Mylonakis, G., Nikolaou, A., Gazetas, G., Soil–pile–bridge seismic interaction: kinematic and inertial effects.

These effects can also be important for monorail bridges on soft soil beds. The main aim of this study is to investigate the effects of Soil-Pile-Bridge-Train Interaction (SPBTI) on the Qom Monorail Bridge (QMB) responses. In spite of many studies on the effects of monorail train-bridge (fixed-base structure) interaction, very little information is available in the literature on the effects of monorail trains on SPB systems. In this paper, an advanced three-dimensional (3D) continuum finite element analysis of QMB subjected to train moving loads was developed. The SPBT models have been validated using three case studies (two bridge-monorail train studies and a soil-pile-structure study) available in the literature. The maximum displacements of the guideway beam at the different train speeds were obtained for various SPBT system conditions. The effects of the stiffness and thickness of the soil, the bridge span length, and the amplitude, length, and geometry of the train loading on the critical speed of the SPBT system are discussed in detail. Finally, the results have been synthesized into simple design charts to select the appropriate straddle-type monorail train and determine its critical speed for a particular soil-bridge condition. In addition, a new simple method for simulating the behavior of the finger-bands (as one of the excitation source of vertical bridge vibrations) in commercial software was presented. The results show that the position of a monorail train bogies plays an important role in determining critical speed so that with uniformity the spacing between the bogies decreases the critical speed in the vertical direction. © 2019 Elsevier Ltd","Finger-band equivalent;

This process therefore needs to be improved. The main aim of this paper is to analyse how to obtain a representative nominal cross-section (NCS) of members, and its influence on determination of the static modulus of elasticity (MOEsta). 21 150 × 200 × 11,000 mm3 Salzmann pine (Pinus nigra subsp. salzmannii (Dunal) Franco) timber rafters from the 18th century Royal Coliseum of Charles III theatre (in Aranjuez, Madrid, Spain) were acoustically tested (by ultrasound, stress wave and vibration). The MOEsta was determined by mechanical testing, and different criteria for determining the NCS were analysed. Good correlation was obtained between the MOEsta and NDT parameters, and the best criterion to assign NCS was proposed to improve the accuracy of the models obtained by reducing the number of NCS measurements. © 2019 Elsevier Ltd","Existing timber structures; Geometric variability; Non-destructive testing; Stress wave; Ultrasound; Vibration","Bridge decks; Elastic waves; Mechanical testing; Timber; Ultrasonic applications; Ultrasonics; Geometric variability; Non destructive testing; Stress wave; Timber structures; Vibration; Nondestructive examination; accuracy assessment; bending; dynamic response; finite element method; numerical model; stiffness; stress analysis; structural analysis; timber; ultrasonics; vibration; wave attenuation; Pinus nigra",,,,,"Ministerio de Economía y Competitividad, MINECO: BIA 2014-55089-P; Universidad Politécnica de Madrid, UPM","Ministerio de Economía y Competitividad [Spanish Ministry of Economy and Competitiveness].

Both of the effects of out-of-plane and in-plane deformations on stress characteristics around the stop-hole were analysed. The stress variation influenced by the stop-hole parameters was analysed by finite element analysis. On this basis, relative fatigue tests of nineteen working conditions were conducted to study the cracking characteristics of cracks initiating from the stop-hole. The effects on delaying crack propagation were compared to determine the optimal stop-hole parameters. The results show that drilling a stop-hole could delay crack propagation. There are multiple high stress sub-regions around the stop-hole, which might induce multiple cracks at the stop-hole edge. It is suggested that the stop-hole should be located on the crack extension line, and the edge of the stop-hole intersects exactly with the crack tip with the stop-hole diameter of 24 mm. © 2019","Crack; Diaphragm; In-plane deformation; Out-of-plane deformation; Stop-hole","Boreholes; Crack propagation; Crack tips; Cracks; Deformation; Diaphragms; Fatigue testing; Infill drilling; Welds; Crack extension; Cracking characteristics; In-plane deformation; Maintenance effect; Out-of-plane deformations; Stop hole; Stress characteristics; Stress variations; Fatigue of materials",,,,,"2017YFE0128700; National Natural Science Foundation of China, NSFC: 51678215, 51678216","The research reported herein has been conducted as part of the research projects granted by the National Key R&D Program of China ( 2017YFE0128700 ) and National Natural Science Foundation of China ( 51678215 , 51678216 ).

In the first step, a concrete short slab bridge was selected at Tehran-Qom old railway line at 168 + 100 km of Tehran. In continue, for measuring field data, the nominated bridge was evaluated under moving train dynamic loads in both presence and absence of TDA layer as a damper material, which was located between the deck slab and ballast layer. In the second step, a 3D finite element model of selected railway bridge was developed, and corresponding results were compared with those obtained from the field and consequently, the numerical model validity was approved. Afterwards, basing on the verified model, a comprehensive parametric study was conducted on train wheel load, train moving speed, and TDA layer thickness to investigate their effects on track–bridge dynamic behavior. © 2019 John Wiley & Sons, Ltd.","FEM modeling;

Therefore, three structures of the SHBD-TCL were proposed, and there are thermally conductive layers and heating cables embedded in different layers. Then, the finite element models corresponding to the above structures were developed. The energy utilization and the deformation caused by the thermal gradient were analyzed, and the embedded spacing and embedded depth were set as input factors. Also, the effective energy ratio and the maximal deformation were set as the optimization targets, and their prediction models were established based on the above input factors. Finally, to obtain greater effective energy ratio and less deformation, the multi-objective optimization was applied to achieve the optimum structure and rational parameters. The optimum structure was selected to conduct the laboratory experiments, which verified the reasonability of the finite element model of SHBD-TCL.

Therefore, the resulting rail stresses and relative rail-deck displacements are limited according to the European design codes. The main parameters to be assessed are the total bridge length and the existence and number of rail and deck expansion joints. In a parameter study of continuous girder pre-stressed concrete bridges, the bridge length limits for 9 different expansion joint combinations are determined by means of non-linear finite element analyses. The temperature changes have a fundamental effect and require that in bridges without rail expansion joints the maximum total bridge length is 144 m with one and 290 m with two deck expansion joints. For bridge lengths close to these values, an individual analysis should prove that rail stress from vertical deflection does not exceed the limit stress. In bridges with at least one rail expansion joint there is usually no length limit. The relative displacement limit between track and structure of 4 mm due to braking and traction force may only be exceeded if the load classification factor α is 1.33 or 1.46. © 2019 Elsevier Ltd","Non-linear analysis; Parametric study; Railway bridge; Track-structure interaction","Concrete bridges; Expansion; Expansion joints; Prestressed concrete; Railroad bridges; Railroads; Rails; Load classification; Non-linear finite-element analysis; Parametric study; Railway bridges; Relative displacement; Temperature changes; Track-structure interaction; Vertical deflections; Structural design; bridge construction; concrete structure; finite element method; nonlinearity; parameter estimation; railway transport; structural response",,,,,,,,,,,,,,,,"Cutillas, A.M., (2009) Track-bridge interaction problems in bridge design, pp. 19-28. , Taylor & Francis; Ruge, P., Birk, C., Longitudinal forces in continuously welded rails on bridge decks due to nonlinear track–bridge interaction (2007) Comput Struct, 85, pp. 458-475; Freystein, H., Track/bridge-interaction – state of the art and examples (2010) Stahlbau, 79 (3), pp. 220-231; Goicolea-Ruigómez, J.M., (2008) Service limit states for railway bridges in new design codes IAPF and Eurocodes, pp. 7-17. , CRC Press; Freystein, H., Geißler, K., Construction and calculation of railway bridges are significantly determined by the interaction track/bridge (2013) Stahlbau, 82 (2), pp. 78-86; Diachenko, L., Benin, A., Diachenko, A., “Track-Bridge” interaction problems in high speed bridge design (2018) Int J Eng Technol, 7, pp. 194-199; Papp, H., Liegner, N., Investigation of internal forces in the rail due to the interaction of CWR tracks and steel railway bridges with ballasted track superstructure (2016) Pollack Period, 11, pp. 65-74; Cuadrado, M., González, P., Track-structure interaction in railway bridges - Step-by-step calculation algorithms (2009) Revista de Obras Públicas, 156 (3499), pp. 38-48; (2001), Union International des Chemins de Fer, UIC Code 774-3-R, “Track/bridge interaction – Recommendations for calculations”, 2nd ed.;; Reguero, A., Types of viaducts on the Madrid-Barcelona-French border high speed railway line (2004) Revista de Obras Públicas, 151 (3445), pp. 109-114; (2008) Instrucción para el proyecto y la ejecución del hormigón estructural, , Ministerio de Fomento Spain; (2003), European Committee for standardization, EN1991-2, Actions on structures – Part 2: General actions – Traffic Loads on Bridges;; Zakeri, J.A., Abbasi, R., Field investigation of variation of rail support modulus in ballasted railway track (2012) Latin Am J Solids Struct, 9, pp. 643-656; Zakeri, J.A., Mosayeb, A., Study of ballast layer stiffness in railway tracks (2016) Gradevinar, 68, pp. 311-318; (2007), Ministerio de Fomento de España, Instrucción sobre las acciones a considerar en el proyecto de puentes de ferrocarril – IAPF-07;; Deutsches Institut für Normung, DIN-Fachbericht 101 Einwirkungen auf Brücken (2009), Beuth Verlag GmbH Berlin; Ruge, P., Widarda, D.R., Schmälzlin, G., Bagayoko, L., Longitudinal track–bridge interaction due to sudden change of coupling interface (2009) Comput Struct, 87, pp. 47-58","Schanack, F.; Institute of Civil Engineering, General Lagos 2086, Chile; email: frank.schanack@uach.cl",,,"Elsevier Ltd",,,,,01410296,,ENSTD,,"English","Eng.

The numerical model considers degree of hydration dependent heat rate, Young's modulus development, strength development and early age tensile and compressive creep behavior. The temperature and stress analyses were performed on two sections of a cast-in-place cap beam (with a cross section of 1.6 m × 2.1 m): one at mid-span of the cap beam and the other on top of the precast column. The results show that the section of the cap beam at the column had high tensile stresses at the mid-sides which exceeded the early age concrete tensile strength when not covered with insulation blankets during construction. Additionally, the use of insulation materials, reduction of initial concrete temperature and proper choice of casting time can significantly mitigate the thermal stress and cracking risk of the cap beam. The model can be conveniently programmed and be a useful tool to help engineers control concrete temperature and take measures to minimize the risk of early-age thermal cracking for cast-in-place pier caps and its connection to a precast column, or other similar concrete members/connections, thus accelerating construction schedules for bridge projects. © 2019 Elsevier Ltd","Cast-in-place cap beam; Casting time change; Early-age thermal cracking; Finite difference; Finite element modeling; Initial concrete temperature; Tensile/compressive creep; Thermal stress; “EACTSA”","Bridges; Casting; Cracking (chemical); Creep; Elastic moduli; Finite difference method; Finite element method; Precast concrete; Risk assessment; Tensile strength; Thermal insulation; Thermal stress; Cap beams; Compressive creep behavior; Concrete temperatures; Construction schedules; Temperature development; Thermal cracking; Thermally induced stress; Time change; Cast in place concrete",,,,,"National Foundation for Science and Technology Development, NAFOSTED: 107.02-2016.25","This research is funded by Vietnam National Foundation for Science and Technology Development (NAFOSTED) under grant number 107.02-2016.25 .",,,,,,,,,,"ACI, A., (2005), 207.1 R-05 Guide to Mass Concrete, American Concrete Institute; Gutsch, A., Rostasy, F.S., Young concrete under high tensile stresses—creep, relaxation and cracking (1995) Thermal Cracking in Concrete at Early Ages, , E & FN Spon London; Kapur, J., (2012), Best practices regarding performance of ABC connections in bridges subjected to multihazard and extreme events; Culmo, M.P., (2009), Connection details for prefabricated bridge elements and systems, No. FHWA-IF-09-010, Federal Highway Administration, United States, Office of Bridge Technology; Ballim, Y., A numerical model and associated calorimeter for predicting temperature profiles in mass concrete (2004) Cem.

The accelerations for the viaduct are hereinafter obtained and are compared between CRTS-III damping track system and conventional CRTS-III track system, and the structure-borne noises for near field and far field of the viaduct are assessed with finite element method (FEM). The acoustic contribution rates for the substructures of the viaduct to the near-field and far-field noises are analyzed. The results reveal that in comparison with the conventional CRTS-III system, the CRTS-III damping track system can mitigate the viaduct acceleration peak with 69.9%, and mitigate the average acceleration with 60.4%. The near field and far field noise measurement points are captured for the CRTS-III damping track system, the sound pressure levels decline by 8.15 dB and 8.36 dB, respectively. The acoustic contribution rates for the viaduct top plate reach 65.28% and 68.30%, respectively. The viaduct top plate thus becomes the major noise source and the damping track system can effectively mitigate the structure-borne noise of the viaduct. © 2019, Korean Society of Civil Engineers.","CRTS-III track system;

The welding process of a deck plate which is welded to a closed trapezoidal stiffener is simulated. A decoupled thermal-mechanical analysis is performed. During the thermal analysis, the temperatures introduced by the passage of the welding torch are calculated for different time steps. This temperature field is used during the thermal analysis to determine the residual welding stresses for the same time steps. The decoupled thermal-mechanical analysis gives the distribution of the residual stresses. For the transverse direction, there are tensile yield residual stresses on the deck plate near the weld region. In between the welded webs of the stiffener, there are compressive residual stresses. For the longitudinal stiffener, there are again tensile yield residual stresses near the weld which decrease at a greater distance and turn into compressive residual yield stresses. For the longitudinal direction, there are tensile yield stresses present near the weld and a compressive residual stress in the middle of the deck plate. The stiffener only shows a small tensile stress peak near the weld root and along the stiffener there are small tensile residual stresses. The results from the finite element analysis are validated by experimental measurements with the incremental hole-drilling method. A residual stress distribution for the top and bottom side of the deck plate and the longitudinal stiffener is determined for both the longitudinal and transverse direction. © 2019 Elsevier Ltd","Finite element modelling; Incremental hole-drilling method; Residual stresses; Welding simulation","Boreholes; Bridge decks; Computer software; Infill drilling; Orthotropic plates; Residual stresses; Thermoanalysis; Welded steel structures; Welding; Welds; Yield stress; Compressive residual stress; Finite element modelling; Incremental hole drilling method; Orthotropic bridge decks; Tensile residual stress; Thermal mechanical analysis; Three dimensional finite elements; Welding simulation; Finite element method",,,,,,,,,,,,,,,,"Wen, S.W., Hilton, P., Farrugia, D.C.J., Finite element modelling of a submerged arc welding process (2001) J.

This study incorporates microencapsulated PCMs as sand-replacement in concrete bridge decks and performs numerical simulation involving multiple interactive length scales to elucidate the influence of PCM-incorporation in concretes subjected to combined freeze-thaw and chloride ingress-induced deterioration. The simulations show significant increase in durability against combined freeze-thaw and chloride ingress-induced deterioration in concretes when microencapsulated PCMs are incorporated. In addition, a reliability-based probabilistic analysis shows significant increase in life expectancy of bridge decks with PCM-incorporation. The numerical approach presented here provides efficient means to develop design strategies to tune dosage and transition temperature of PCMs to maximize durability of concrete structures in regions that experience significant winter weather conditions. © 2019 Elsevier Ltd","Chloride ingress; Damage; Durability; Finite element; Freeze-thaw; Microstructure; Phase change materials (PCMs)","Bridge decks; Chlorine compounds; Concretes; Deterioration; Durability; Finite element method; Freezing; Microencapsulation; Microstructure; Numerical models; Reliability analysis; Thawing; Chloride ingress; Damage; Durability of concrete structure; Freeze-thaw; Microencapsulated phase change material; Numerical approaches; Probabilistic analysis; Winter weather conditions; Phase change materials",,,,,"University of Rhode Island, URI","The authors acknowledge the support from Department of Civil and Environmental Engineering (CVE) and College of Engineering (COE) at the University of Rhode Island (URI) towards this study.",,,,,,,,,,"Bentz, D.P., Turpin, R., Potential applications of phase change materials in concrete technology (2007) Cem.

A modified overlay is usually used to strengthen an orthotropic steel bridge deck, and the strengthening effect of the modified overlay is the primary focus of attention of this paper. To compare the mechanical property and stability of different strengthening solutions, a simply supported steel box girder bridge was strengthened using the sandwich plate system (SPS) and reactive powder concrete (RPC) solutions. Based on actual bridge data, the authors conducted a 7-year in situ mechanical performance test and follow-up investigation on the service conditions of the orthotropic composite steel bridge deck. Research results show that the mechanical performance and deformation of the longitudinal ribs and decks were both significantly improved. For SPS and PRC, the average stress on longitudinal ribs (decks) has been decreased by 52% (70%) and 81% (95%), respectively. Similarly, the deflection of longitudinal ribs (decks) was improved by 70% (75%) and 82% (86%), respectively. Moreover, no apparent degradation of mechanical performance was observed; the improving effects on the average stress of the SPS and PRC solutions were relatively stable. In addition, the stress and deformation of the SPS steel composite deck were positively correlated with temperature. Furthermore, serious damage in the initial overlay of the SPS solution were observed during the test. Based on a comparative analysis with a case in Germany and finite-element analysis, the effects of ambient temperature, the structure type of the deck, and the thickness of the SPS system should be taken into consideration when the SPS is applied to those bridges built in subtropical or tropical zones. © 2019 American Society of Civil Engineers.","Composite bridge deck system; Deflection; Field test; Orthotropic steel deck; Reactive powder concrete; Sandwich plate system; Stress","Box girder bridges; Composite bridges; Concretes; Deflection (structures); Deformation; Microalloyed steel; Orthotropic plates; Steel bridges; Strengthening (metal); Stresses; Tropics; Field test; Mechanical performance; Orthotropic composites; Orthotropic steel bridge decks; Orthotropic steel decks; Reactive powder concrete; Sandwich plate systems; Stress and deformation; Bridge decks",,,,,,,,,,,,,,,,"Buitelaar, P., Braam, R., Kaptijn, N., Reinforced high performance concrete overlay system for steel bridges (2004) Proc.

An experiment device is developed to measure the friction coefficients of three contact pairs within the tensioner. Statistic results of test data show that the friction coefficient is linearly dependent on normal forces, and thus a linear function is used to describe it. An exact mathematical model and an accurate three-dimensional finite element model are proposed in this study to calculate the relationship of friction torque and rotation angle as well as the damping characteristics of the tensioner. The mathematical model and three-dimensional finite element model are verified through an experiment. Comparison indicates that both the mathematical and finite element model can accurately predict the working torque of the tensioner during operation process, while the finite element model has better accuracy in predicting the damping characteristics than the mathematical model. © IMechE 2018.","damping characteristics;

These blocks can satisfy thermal performance requirements without the need of additional insulation. However, these requirements in the building regulations only consider thermal, but neglect moisture aspects. This paper presents a comparative analysis of steady-state numerical conjugated heat-and moisture transport FEM simulations of masonry walls. The hygrothermal material properties of the insulation filled masonry blocks were measured in laboratory. In the paper, besides a wall section, a wall corner joint is presented, both modeled in 2D from complex building elements, such as insulation filled blocks, and were tested using different fillers (aerogel, expanded perlite, expanded polystyrene, mineral wool and PUR foam), respectively. Monthly variation of the fillers’ thermal conductivity, thermal and moisture transmittance and effective water vapor diffusion resistance of the walls, as well as linear thermal and moisture transmittance of the wall corner joints were examined in details. A comparison between detailed and simplified modeling were also carried out. The evaluation of the results shows that there are noticeable differences in trends between thermal and moisture transmittances, latter show significantly greater variation and depends mainly on the hygrothermal behavior of the filler. Based on effective water vapor resistance factors, we showed that assuming the same vapor transmission properties for all type of filled masonry blocks is a mistake. © 2019, Budapest University of Technology and Economics.

Most of these bridges are several decades old and have been subjected to continuous dynamic loadings, due to the vehicular traffic, and in many cases their maintenance required structural modifications. The currently adopted health monitoring strategies are based on in situ inspections as well as structural assessments based on numerical models characterised by different levels of reliability according to the required purpose. Simplified approaches are generally adopted for fast structural evaluation, on the other hand more rigorous approaches are fundamental for a reliable structural assessment of these particular structures, often characterized by very complex geometrical layouts and structural alterations not always sufficiently documented. This paper presents an original Discrete Macro-Element Method (DMEM) that allows a reliable simulation of the linear and nonlinear response of masonry structures and masonry bridges characterised by a lower computational burden, compared to classical nonlinear FEM analyses, although maintaining a good accuracy. The method is applied to a real masonry bridges and the results are compared with those obtained from a more sophisticated three-dimensional nonlinear FEM model both in linear and nonlinear context. © 2019 IABSE.

The results from eight laboratory tests performed on both reinforced and unreinforced adobe arches are used to define the index. The arches are damaged up to collapse using pseudo-static test cycles carried out by applying progressive controlled displacements at third span. The test records allow to follow the stiffness degradation of each arch by plotting the relative force–displacement curves, as well as to track their frequencies variation during the damage evolution by means of dynamic identification tests performed at the end of each cycle. The new index considers the bending moment as the main cause of damage for the analysed arches; therefore, starting from the bending stiffness, a damage indicator was developed and experimentally validated, as function of the frequency reduction, respect to the undamaged scenario. Finally, the index is also validated for different types of arch collapse mechanisms through Finite Element Modelling. © 2020 Elsevier Ltd","Adobe arches; Damage detection; Dynamic identification; Finite Element Method; Operational Modal Analysis; Pseudo-static tests; Stiffness-frequency correlation","Arch bridges; Arches; Stiffness; Bending stiffness; Collapse mechanism; Displacement curve; Dynamic identification; Finite element modelling; Frequency reduction; Pseudo-static tests; Stiffness degradation; Damage detection",,,,,,,,,,,,,,,,"Valente, M., Milani, G., Seismic assessment of historical masonry towers by means of simplified approaches and standard FEM (2016) Constr.

In this paper, the temperature distribution at a particular segment of a prestressed concrete girder bridge from the John James Audubon Bridge Project in Louisiana is quantified for different days of the year. Computed temperatures, actual observed temperature at the bridge site, and AASHTO specified gradients are presented and compared. It was found that AASHTO temperature gradient matches the measured temperature well at the site with some exceptions. The restraint moment caused by the temperature gradient was quantified and compared with the cracking moment of girder ends. Primary and secondary thermally induced stresses were then calculated for different girders. It was found that temperature gradient alone does not produce stresses that exceed the girder section’s cracking limits for the investigated bridge. However, the cumulative effect of the primary thermal stresses and additional positive restraint moment due to thermal gradients and other long-term effects may well exceed the tensile strength of concrete and cause cracking. © 2020 Informa UK Limited, trading as Taylor & Francis Group.","concrete bridges; continuous bridges; diurnal and seasonal temperature variations; finite element method; prestressed concrete; structural behaviour; structural health monitoring; Thermal effects","Concrete beams and girders; Concrete bridges; Finite element method; Prestressed concrete; Structural health monitoring; Temperature distribution; Tensile strength; Thermal effects; Thermal gradients; Climatological conditions; Continuous bridges; Geographical locations; Measured temperatures; Seasonal temperature variations; Strength of concrete; Structural behaviour; Thermally induced stress; Atmospheric temperature",,,,,"Louisiana Transportation Research Center, LTRC: 08-1ST","Field data used in this study was generated as part of a research project sponsored by Louisiana Transportation Research Center (LTRC Project No. 08-1ST) with Dr. Walid Alaywan as Project Manager.

Seismic isolation is a strategy that protects the bridges from dynamic forces by increasing their natural periods. Despite the widespread use of seismic base isolation in conventional bridges, there are very limited reports on the use of this technique on monorail bridges. The seismic isolation technique can also be useful for the straddle-type monorail transportation systems. This study aims to investigate the nonlinear performance of the Qom Monorail Bridge (QMB), which is seismically isolated by an isolation system that takes the soil-pile-bridge-train interaction under strong earthquakes into consideration using the 3D finite element method. Results showed that the isolation system can eventually reduce the base shear by 60% and controls the distribution of the forces between the soil and piles. The dynamic monorail train system acts as a damper on the nonisolated QMB. However, the presence of the train on the isolated QMB with the pier height of 15 m or more can increase the base shear. © 2020 American Society of Civil Engineers.",,"Earthquakes; Soils; Urban transportation; 3-D finite element method; Bridge-train interaction; Seismic base isolation; Seismic Performance; Straddle type monorail; Strong earthquakes; Transportation system; Urban transportation networks; Piles",,,,,,"To investigate the effects of SPBTI, a monorail bridge project located in Qom, Iran was selected (Fig. 2). The Qom monorail project, which is the first straddle-beam monorail system in Iran, is designed to carry 12,000 passengers when it opens to the public in the first operation phase and 19,000 passengers in 2026. This monorail bridge system includes guideway beams, decks, piers, pile caps, and pile groups. According to Qom Urban Railway Organization (QURO), each pile cap is supported by four concrete piles. The cross-sections of the piles and the piers are circular with diameters of 1.2 and 1.6 m, respectively. The nominal length of the piles ranges from 7 to 10 m and hence a typical length of 8 m was adopted in this study. The nominal height of the piers varies from 9 to 15 m. The guideway structure comprises individually precast box concrete beams with a void in the middle to reduce the weight of the bridge. This study evaluated seismic responses of QMB with Fig. 2.

As a new structure, investigations into the static structural performance under the serviceability limit state are desired for examining the structural integrity of the developed bridge when subjected to unsymmetrical loadings characterized by combined torsion and bending. In this study, a full-scale experimental inspection was conducted on a fabricated bridge, and the combined flexural–torsional behavior was examined in terms of displacement and strains. The experimental structure showed favorable strength and rigidity performances to function as deployable bridge under unsymmetrical loading conditions and should be designed in accordance with the stiffness criterion, the same as that under symmetrical loads. In addition, a finite element model (FEM) with a simple modeling process, which considered the multi segments of the FRP members and realistic nodal stiffness of the complex unique hybrid nodal joints, was constructed and compared against experiments, demonstrating good agreement. A FEM-based numerical analysis was thereafter performed to explore the effect of the change in elastic modulus of different FRP elements on the static deformation of the bridge. The results confirmed that the change in elastic modulus of different types of FRP element members caused remarkable differences on the bending and torsional stiffness of the hybrid bridge. The global stiffness of such a unique bridge can be significantly enhanced by redesigning the critical lower string pull bars using designable FRP profiles with high elastic modulus.

The research aims are to design a monolithic mechanism with capability of working in three translational axes and having a high resonant frequency. As a result of being precise in rotation, circular flexure hinges are adopted in the structure of the proposed mechanism and its corresponding mathematical modeling is investigated. A finite element analysis (FEA) model is developed to perform analysis and predict the behaviour of the proposed mechanism and the utilized amplifier, and thus establish the computational Jacobian, workspace and amplification ratio. The stress-strain relationship of the proposed mechanism is investigated by applying safety factor and the results are presented. Finally, an experimental study is conducted to evaluate the dynamic and tracking performances of the proposed flexure-based spatial mechanism. A feedback Proportional-Integral (PI) control methodology is implemented to enhance the mechanism positioning performance and eliminate hysteresis effect inherent in piezoelectric actuators. Based on the designed parameters, the proposed manipulator can have a large workspace, high band-width frequency, and fine tracking resolution along each working axes. © 2020, Springer-Verlag GmbH Germany, part of Springer Nature.","Compliant parallel micromanipulator;

In this method, a dynamic bearing property definition is introduced to account for the temperature variation caused by the absorbed earthquake energy and the corresponding property variation of LRBs. Under low temperature conditions, the base isolation effect of LRBs which are well-designed for room temperature is significantly weakened, manifested by shorter fundamental structural natural periods and more damages and forces imposed to structure members, such as a 5–13% increment of shear force transferred by the LRBs, an increasing area of the hysteresis loop of the bending moment at the bottom of piers, and an increasing residual displacement at the top of piers. In addition, through jointed investigating the seismic responses under both long and short durations of earthquake motions, it is demonstrated that the heat production in LRBs over an earthquake can alleviate the detrimental effect of low temperature, and the extent of this alleviation is positively correlated to the earthquake duration. Therefore, the low temperature effect and the property variation of LRBs over an earthquake should be comprehensively considered for the designation of LRBs installed in bridge viaducts located in cold regions and the realization of an accurate seismic analysis of the bridge viaducts. © 2019 Elsevier Ltd","Bridge; Low temperature; LRB; Nonlinear dynamic analysis; Seismic isolation","Bearings (structural); Bridges; Dynamics; Earthquakes; Low temperature effects; Nonmetallic bearings; Numerical methods; Piers; Rubber; Seismic response; Shear flow; Temperature; Bearing properties; Earthquake motion; Lead rubber bearing; Low temperature conditions; Low temperatures; Residual displacement; Seismic isolation; Temperature variation; Low temperature production; bridge; cold region; dynamic analysis; dynamic response; earthquake engineering; low temperature; nonlinearity; road; seismic design; seismic isolation; seismic response; viaduct",,,,,,,,,,,,,,,,"Abdel-Salam, M.N., Heins, C.P., Seismic response of curved steel box girder bridges (1988) J Struct Eng, 114 (12), pp. 2790-2800; Desroches, R., Fenves, G.L., Evaluation of recorded earthquake response of a curved highway bridge (1997) Earthq Spectra, 13 (3), pp. 363-386; Hayashikawa, T., Otake, A., Nakajima, A., Nonlinear behavior of curved viaducts subjected to three-dimensional earthquake ground motions.

A nondestructive testing method using eddy current, however, exhibits remarkable capabilities in quantitatively monitoring the formation of these artificial defects in metal materials. Owing that the commonly appeared defect species in metal structures is slit defect instead of cylindrical defect, a deeper understanding of the magnetic testing signal correlated to slit defects in eddy current nondestructive method is required. In this paper, based on pervious investigation on cylindrical defect, a semi-analytical method for the magnetic field of a slit defect in eddy current testing system is proposed. Firstly, an analytical expression to the magnetic field for a cylindrical defect in metal is briefly introduced. Then, a model with an elliptical cylindrical defect is studied, and a semi-analytical method is deduced in details. Next, a semi-analytical formula is proposed to calculate the magnetic signals generated by slit defect. Finally, with a case study, the proposed semi-analytical method is applied to calculate the slit defect magnetic testing signal for slit defect in eddy current technique. The results indicated that the maximal relative errors between the semi-analytical solution and FEM are less than 2 % and the computation efficiency is higher than 10 times. With the support of these results, not only our proposed semi-analytical method can be readily used to investigate the forward problem due to the slit defects in eddy current technique, but also it can be further extended to seek the theoretical expression for defects with complex shapes, including those natural defects in conductive metal components (e.g. defects in oil pipe, rail track, iron bridge, oil tank, ocean ship). © 2019 Elsevier B.V.","Eddy current nondestructive technique; Magnetic potential vector; Metal; Semi-analytical method; Slit defect","Defects; Magnetic fields; Metals; Oil tanks; Eddy current techniques; Magnetic potentials; Non-destructive technique; Nondestructive methods; Nondestructive testing method; Semi-analytical formulae; Semi-analytical methods; Semi-analytical solution; Eddy current testing",,,,,"Natural Science Foundation of Guangdong Province: 2018A030313893; National Aerospace Science Foundation of China: 61527803; Fundamental Research Funds for the Central Universities: ZYGX2018J067","Th work is supported by the National Nature Science Foundation of Guangdong Province [grant number is 2018A030313893], the Fundamental Research Funds for the Central Universities [grant number is ZYGX2018J067] and the National Nature Science Foundation of China [grant number is 61527803].","Th work is supported by the National Nature Science Foundation of Guangdong Province [grant number is 2018A030313893 ], the Fundamental Research Funds for the Central Universities [grant number is ZYGX2018J067 ] and the National Nature Science Foundation of China [grant number is 61527803 ].

Due to the severity, generality and various safety and economic problems caused by this phenomenon, it is necessary to establish a model for predicting the stress corrosion cracking growth rates. This paper provides an overview of three main methods for predicting stress corrosion cracking growth rates in recent decades, i.e., empirical, deterministic and calculation methods, which are introduced in detail. Empirical models describe classical statistical analysis and emerging artificial neural network method, both of which are based on a large number of experimental test data mining. They are convenient and relatively accurate in predicting, but require extensive, time-consuming and expensive tests for different service environments. Deterministic models aim to establish a theoretical relationship between crack growth rate and various influencing parameters by studying the stress corrosion cracking mechanism. Many scholars have proposed different mechanisms to scientifically explain the stress corrosion cracking phenomenon and propose corresponding crack growth rate models. Calculation models reveal the mechanism of crack initiation and propagation in different layers of materials by means of finite element method based on fracture mechanics and multiscale method based on quantum mechanics. They provide new idea for future research on stress corrosion cracking and bridge the quantitative mechanism or model, but no specific stress corrosion cracking growth rate model is formed. The article concludes with the prospect, aim and direction for stress corrosion cracking mechanism and prediction model. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.",,"Backpropagation; Crack propagation; Cracks; Data mining; Forecasting; Growth rate; Light water reactors; Neural networks; Nuclear energy; Nuclear fuels; Nuclear power plants; Quantum theory; Residual stresses; Artificial neural network methods; Calculation models; Crack initiation and propagation; Deterministic models; Different mechanisms; Different services; Economic problems; Influencing parameters; Stress corrosion cracking",,,,,"Beijing Municipal Science and Technology Commission: Z181100005218005","The authors acknowledge the financial supports from the Beijing Municipal Science & Technology Commission (Z181100005218005).

Using the Oujiang River North Estuary Bridge which is a three-tower four-span suspension bridge under construction in China as an example, this paper investigates the mechanical performance of two sub-systems Ⅰ and Ⅱ of double-deck plate-truss composite steel girders. System Ⅰ is the main bridge system, with the steel plate deck and the longitudinal ribs acting as a part of the main carrying members of the bridge. System Ⅱ is the stiffened steel plate deck consisting of the longitudinal ribs, diaphragms and the deck plate as their common upper flange, acting as a bridge floor. Three-dimensional finite element models (FEM) are developed and different load cases are considered for System Ⅰ and System Ⅱ in the analysis. The results show that 60–80% of total load is carried by the deck plate and longitudinal ribs in System Ⅰ, and the mechanical response of System Ⅱ is susceptible to live load. Finally, a parametric study is conducted to investigate the influences of various structural parameters on the mechanical performance of double-deck plate-truss composite steel girders. The obtained analytical results lead to a better understanding of the complex mechanical performance of steel deck-truss composite system, particularly with respect to stress distribution and load carrying mechanism. © 2019 Elsevier Ltd","Component structural system; Mechanical performance; Plate-truss composite steel girders; Three-tower suspension bridge","Plates (structural components); Steel beams and girders; Suspension bridges; Trusses; Analytical results; Composite steel; Mechanical performance; Mechanical response; Steel plate decks; Structural parameter; Structural systems; Three dimensional finite element model; Suspensions (components); bridge; composite; finite element method; loading; mechanical property; steel structure; three-dimensional modeling; China; Oujiang Estuary; Zhejiang",,,,,"Ministry of Science and Technology of the People's Republic of China, MOST: SLDRCE19-B-09; National Key Research and Development Program of China, NKRDPC: 2018YFC0809600, 2018YFC0809601; Fundamental Research Funds for the Central Universities: 22120180316","This work presented herein has been supported by the National Key Research and Development Program of China under grant numbers 2018YFC0809600 and 2018YFC0809601 , the Ministry of Science and Technology of China under grant number SLDRCE19-B-09 and the Fundamental Research Funds for the Central Universities of China under grant number 22120180316 .

A deflection function and the energy method are adopted to build the nonlinear equilibrium formulae, by solving which, the analytical solution is expressed explicitly. Subsequently, a numerical simulation is established to track the load-displacement paths of equilibrium. The simulation results indicate the load drops significantly after its maxima (critical buckling load) and follows multiple branches characterized by load limits and displacement limits. A comparison is taken between the numerical and analytical results, and a good accordance is depicted. Moreover, parameters that may affect the buckling load are analyzed, with the inclusion of rotational stiffness supports, the central angle, as well as the normalized thickness on the load capacity. Finally, both the proposed theoretical formule and simulation results agree excellently with the test results and other closed-form expressions published elsewhere. © 2019, Korean Society of Civil Engineers.","circular arch; elastic buckling; finite element model; point load; rotational stiffness; stability","Arch bridges; Arches; Convergence of numerical methods; Finite element method; Stiffness; Thin walled structures; Circular arches; Closed-form expression; Critical buckling loads; Elastic buckling; Nonlinear buckling; Nonlinear equilibrium; Point load; Rotational stiffness; Buckling",,,,,,,,,,,,,,,,"(2013) User’s Manual: Version 6.12, , Simulia, Providence, RI, USA; Allen, H.G., Bulson, P.S., (1980) Background to buckling, , McGraw-Hill, London, UK; Bažant, Z.P., Cedolin, L., (2010) Stability of structures: Elastic, inelastic, fracture and damage theories, , World Scientific, Hackensack, NJ, USA; Belytschko, T., Glaum, L.W., Applications of higher order corotational stretch theories to nonlinear finite element analysis (1979) Computers & Structures, 10 (1-2), pp. 175-182; Boot, J.C., Elastic buckling of cylindrical pipe linings with small imperfections subjected to external pressure (1998) Trenchless Technology Research, 12 (1-2), pp. 3-15; Boot, J.C., Naqvi, M.M., Gumbel, J.E., A new method for the structural design of flexible liners for gravity pipes of egg-shaped cross-section: Theoretical considerations and formulation of the problem (2014) Thin-Walled Structures, 85, pp. 411-418; Bradford, M.A., Uy, B., Pi, Y.L., In-plane elastic stability of arches under a central concentrated load (2002) Journal of Engineering Mechanics, 128 (7), pp. 710-719; Chang, C.S., Hodges, D.H., Stability studies for curved beams (2009) Journal of Mechanics of Materials and Structures, 4 (7-8), pp. 1257-1270; Dickey, R.W., Roseman, J.J., Symmetric and unsymmetric buckling of circular arches (1996) Quarterly of Applied Mathematics, 54 (4), pp. 759-775; Dickie, J.F., Broughton, P., Stability criteria for shallow arches (1971) Journal of the Engineering Mechanics Division, 97 (3), pp. 951-965; Gambhir, M.L., (2004) Stability Analysis and Design of Structures, , Springer, New York, NY, USA; Gjelsvik, A., Bodner, S.R., Energy criterion and snap-through buckling of arches (1962) Journal of the Engineering Mechanics, 88, pp. 87-134; Kang, Y.J., Yoo, C.H., Thin-walled curved beams.

In this paper, an arm is regarded as a variable thickness beam that covers both lumped and distributed configurations, and thus a nonlinear closed-form model of compliant bridge-type mechanisms is developed through considering load effect. Then, application limitations, displacement amplification ratio, input compliance, and influence of actuator are discussed to quantitatively evaluate the influences of design parameters and capture the nonlinear characteristics of compliant bridge-type mechanisms. Finally, the analytical model is verified by finite element analysis (FEA) and experiments, and the results show that the proposed model can accurately predict the deformation of compliant bridge-type mechanisms. © 2019 Elsevier Inc.","Bridge-type mechanism; Displacement amplification ratio; Input compliance; Load effect; Nonlinear characteristics","Engineering; Precision engineering; Bridge-type mechanisms; Displacement amplification; Input compliance; Load effects; Nonlinear characteristics; Bridges",,,,,"National Natural Science Foundation of China, NSFC: 51605028, 51975022, 91748205","The authors gratefully acknowledge the financial support of National Natural Science Foundation of China (Grant Nos. 51975022 , 91748205 , 51605028 ).",,,,,,,,,,"(2013) Handbook of compliant mechanisms, , John Wiley & Sons Incorporated; Chen, C.M., Hsu, Y.C., Fung, R.F., System identification of a Scott–Russell amplifying mechanism with offset driven by a piezoelectric actuator (2012) Appl Math Model, 36 (6), pp. 2788-2802; Chen, G., Ma, Y., Li, J., A tensural displacement amplifier employing elliptic-arc flexure hinges (2016) Sens Actuators A Phys, 247, pp. 307-315; Lee, H.J., Kim, H.C., Kim, H.Y., Optimal design and experiment of a three-axis out-of-plane nano positioning stage using a new compact bridge-type displacement amplifier (2013) Rev Sci Instrum, 84 (11), p. 115103; Wang, F., Liang, C., Tian, Y., Design and control of a compliant microgripper with a large amplification ratio for high-speed micro manipulation (2016) IEEE ASME Trans Mechatron, 21 (3), pp. 1262-1271; Lee, H.J., Kim, H.C., Kim, H.Y., Optimal design and experiment of a three-axis out-of-plane nano positioning stage using a new compact bridge-type displacement amplifier (2013) Rev Sci Instrum, 84 (11), p. 115103; Abdelnaby, M.A., Arafa, M., Motion amplification using a flextensional compliant mechanism for enhanced energy harvesting (2016) Active and passive smart structures and integrated systems 2016.

This is important because while it is widely accepted that correct simulation of boundary conditions in a Finite Element (FE) model is crucial to the accuracy of the model, few researchers have actually attempted to measure bearing movement as part of their model updating strategy. To demonstrate the approach and the benefits of tracking bearing movement two separate updated FE models of the bridge were developed; (i) was updated using dynamic performance information, and (ii) was updated using response to quasi-static loading. The inclusion of bearing behaviour data proved to be very important, as in (i) it was found that during ambient vibration testing with low level dynamic response to light traffic, the friction on the bridge bearings was such that they were effectively behaving as ‘pinned-pinned’, as opposed to ‘pinned-roller’ as indicated by the bridge drawings. Using this observation it was possible to get the updated model (i) to match very closely with the experimentally measured frequencies and mode shapes. Without this information, conventional model updating optimisation would likely have driven the system parameters (e.g. Young's modulus, deck mass) to unrealistic values in order to get the FE predictions to match the experimentally observed frequencies. For the static model (ii) it was again observed that friction on the bearing was playing a significant role in the behaviour of the bridge and this was exploited to develop a simple but effective updated FE model that accurately predicted the bridge response during two separate static load tests. No single FE model could represent the bridge for both types of loading but in both cases the bearing performance data were critical in getting the relevant model to match the experimentally observed values. © 2019 Elsevier Ltd",,"Boundary conditions; Bridge bearings; Elastic moduli; Friction; Load testing; Ambient Vibration Testing; Bearing performance; Conventional modeling; Dynamic performance; Finite-element model updating; Low-level dynamics; Quasi-static loading; Static load tests; Finite element method; bearing capacity; boundary condition; bridge; dynamic response; finite element method; loading test; vibration",,,,,"Seventh Framework Programme, FP7: 330195; FP7 People: Marie-Curie Actions; Seventh Framework Programme, FP7","The research leading to these results has received funding from the People Programme (Marie Curie Actions) of the European Union's Seventh Framework Programme (FP7/2007-2013) under grant agreement n° 330195.

A three-dimensional solid finite element model has been established to carry out a parametric analysis of the main influences on the stress concentration factors for CHS K-joints using the general software MSC.MARC. A novel stress concentration factor method based on the CHS K-joint stiffness has been proposed by combining a theoretical derivation and a regression analysis. The results reveal that the hot spot stress of a CHS K-joint can be obtained with a linear extrapolation. The location of the maximum hot spot stress appears on the crown toe point of the chord and tensile brace intersection welding seam near the chord intersecting line. A fatigue crack in a CHS K-joint belongs to the opening Class I crack category. When the fatigue crack penetrates the full thickness of the chord, the fatigue crack develops rapidly; the fatigue failure of the CHS K-joint belongs to the brittle failure category in the elastic range. A coupling action caused by the geometric parameters is demonstrated to exist in the stress concentration factor of CHS K-joints. Given the current stress concentration factor method for CHS K-joints is based on a regression analysis using a single geometric parameter, this limitation impacts its application in accurately in developing bridge structures. The novel stress concentration factor method encompassing the CHS K-joint stiffness proposed in this paper considers the coupling action on the stress concentration factor caused by the joint geometric parameters, in addition to improving the conservativeness and accuracy in evaluating and calculating the stress concentration factors of CHS K-joints used in bridge structures. © 2019","Calculating method; Circular hollow section (CHS) K-joint; Fatigue failure mode; Fatigue performance testing; Full-scale model; Hot spot stress; Joint stiffness; Stress concentration factor (SCF)","Beams and girders; Cracks; Factor analysis; Fatigue crack propagation; Fatigue testing; Finite element method; Geometry; Joints (structural components); Regression analysis; Seam welding; Stiffness; Stress concentration; Calculating methods; Fatigue failure mode; Fatigue performance; Full-scale modeling; Hot spot stress; Joint stiffness; K-joint; Stress concentration factors; Fatigue of materials; experimental study; failure analysis; fatigue; finite element method; joint; research; stress analysis; three-dimensional modeling",,,,,"Natural Science Foundation of Fujian Province: 2019J06009; National Basic Research Program of China (973 Program): 2017YFE0130300","This research work was supported by the National Key Research and Development Program of China (No. 2017YFE0130300 ) and the Natural Science Foundation of Fujian Province , China (No. 2019J06009 ).

As an attempt, this study aims to propose a sparse regularization-based method for detecting the structural damage using structural responses caused by unknown moving forces. First, a transmissibility matrix between two sensor sets is constructed using a known bridge model and least square-based moving force identification algorithm. Second, the measured responses are used as inputs to estimate the reconstructed responses with the help of the transmissibility matrix. Then, the damage detection procedure can be regarded as an optimization problem trying to find a possible damage vector, which makes the difference between the measured and reconstructed responses minimum. Lp-norm (0 &lt; p ≤ 1) sparse regularization is adopted to improve the ill-conditioned SDD problem. To assess the feasibility of the proposed method, damaged bridges subjected to moving forces are taken as examples for numerical simulations. Differences between finite element model (FEM) used for model updating and the one applied to simulate the true damage conditions are considered. The illustrated results show that the proposed method can identify structural damages with a strong robustness. Some related issues, such as regularization parameters, finite element models, Lp-norm (0 &lt; p ≤ 1) penalty terms, noise levels and damage patterns, are discussed as well. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.","Sparse regularization; Structural damage detection (SDD); Structural health monitoring (SHM); Unknown moving force","Finite element method; Numerical methods; Structural analysis; Structural health monitoring; Moving force identification; Moving forces; Optimization problems; Regularization parameters; Sparse regularizations; Structural damage detection; Structural health monitoring (SHM); Structural response; Damage detection",,,,,"National Natural Science Foundation of China, NSFC: 51278226, 51678278","This work was jointly supported by the National Natural Science Foundation of China with Grant numbers 51678278 and 51278226.

Since most of the fjords are wide and deep, construction of traditional bridges with fixed foundations is not possible. Therefore, floating bridge concepts are proposed for the fjord-crossing project. Since the floating foundations of the bridges are close to the water surface, the concern of accidental ship collisions is raised. Considering the displacement and speed of the passing ships and the significant compliance of the bridge, interaction between the bridge and the ship can be significant should a collision occur. Many studies have been conducted on ship collision with bridge structures with a special focus on bridge piers. However, the research on ship collision with bridge girders is quite limited. The purpose of this study is to investigate the collision response of a floating bridge for ship-girder collision events. Both the local structural damage and the global dynamic response of the bridge are assessed. Local structural deformation and damage are first investigated by numerical simulations with detailed finite element (FE) models in LS-DYNA. Subsequently, the bridge global response to the collision loads is analyzed in USFOS using the force-deformation curves from the local analysis. By combining the local and global analysis results, a comprehensive overview of the bridge response during ship-girder collisions can be obtained. © 2019 by ASME.",,"Beams and girders; Damage detection; Deformation; Movable bridges; Public administration; Ships; Bridge structures; Collision events; Collision response; Floating foundations; Force - deformation curves; Local and global response; Structural damages; Structural deformation; Highway bridges; bridge construction; collision; compliance; damage; displacement; dynamic response; finite element method; fjord; floating offshore structure; foundation; public transport; velocity; vessel; Norway",,,,,"Senter for Autonome Marine Operasjoner og Systemer, AMOS: 223254","The Norwegian Public Roads Administration (Project No. 328002).

The core concept of the research, developed by the first author, is prefabrication of UHPC shell which acts as a stay-in-place formwork. In the proposed approach, after transporting the UHPC shell to site, the construction of structural elements is completed by placing reinforcing cage inside the UHPC shell and post-pouring with normal concrete. The superior properties of UHPC provide excellent means to enhance the service life of bridge elements, while eliminating the need for assembling or stripping of formwork. As a proof of concept, a combination of experimental and numerical studies was conducted, results of which are reported here. Before conducting experimental work, numerical study in the form of finite element analysis was carried out to investigate performance of shell during placement of the normal concrete. To provide a baseline comparison between UHPC shell formwork and conventional methods, two test specimens were constructed and tested under three-point load setup. The shell test specimen demonstrated flexural strength, 14% greater than an equivalent normal strength concrete specimen. The UHPC shell test specimen failure occurred by debonding of shell at the interface and development of a large crack in the shell. The shell test specimen exhibited improved levels of ductility before failure. The preliminary analysis demonstrated that the idea is feasible and useful for accelerated bridge construction applications. © National Academy of Sciences: Transportation Research Board 2019.",,"Bridges; Concrete placing; Shells (structures); Accelerated bridge constructions; Conventional methods; Experimental and numerical studies; Feasibility studies; Normal strength concretes; Preliminary analysis; Structural elements; Ultra high performance concretes; High performance concrete",,,,,"U.S. Department of Transportation, DOT; Florida International University, FIU","This project is supported by the U.S. Department of Transportation through the Accelerated Bridge Construction University Transportation Center (ABC-UTC) at Florida International University.

Vibration-based damage detection has several advantages compared to traditional methods of non-destructive evaluation, such as ground penetrating radar (GPR) or ultrasonic testing, since they give a global response and are feasible for large structures. Damage detection requires a comparison between two systems states, the baseline or “healthy state”, i.e., the initial modal parameters, and the damaged state. In this study, system identification (SI) was carried out on a pedestrian bridge by measuring the dynamic response using six low-cost triaxial accelerometers. These low-cost accelerometers use a micro-electro-mechanical system (MEMS), which is cheaper compared to a piezoelectric sensor. The frequency domain decomposition algorithm, which is an output-only method of modal analysis, was used to obtain the modal properties, i.e., natural frequencies and mode shapes. Three mode shapes and frequencies were found out using system identification and were compared with the finite element model (FEM) of the bridge, developed using the commercial finite element software, Abaqus. A good comparison was found between the FEM and SI results. The frequency difference was nearly 10%, and the modal assurance criterion (MAC) of experimental and analytical mode shapes was greater than 0.80, which proved to be a good comparison despite the small number of accelerometers available and the simplifications and idealizations in FEM. © 2019 by the authors.

To achieve the objective of this study six models are developed using ABAQUS with six different cable spacing ((8.04 m, 30 cables), (9.42, 25), (11.11, 22), (13.72, 18), (15.56, 16), and (16.67, 15)). Firstly, a non linear static finite-element analysis is performed on the models; then pre-tensioning forces are applied to cables, after that the shape modes for each model are presented. Secondly, a nonlinear dynamic analysis is performed on the models; the results obtained from the finite-element analysis are used in the optimization. The results show that the maximum vertical deflection decreased and the cable stress increased with the increasing of cable spacing for both static and dynamic analysis. As a result, the unsupported length increased with the cable spacing increasing; this will lead to larger deflection and greater stresses in the cables. Finally, the optimum cable spacing is 11.2 m based on static and dynamic deflection and cable stress. © Al-Rousan, Rajai, 2019.","Cable-stayed bridge; Civil engineering; Engineering; Structural concrete deck; Technology","Cable stayed bridges; Civil engineering; Engineering; Finite element method; Cable stress; Dynamic deflections; Nonlinear statics; Static and dynamic analysis; Structural concretes; Vertical deflections; Vertical deformation; Cables",,,,,"Jordan University of Science and Technology, JUST","The authors acknowledge the technical support provided by the Jordan University of Science and Technology.",,,,,,,,,,"Negrão, J., Simões, L., Optimization of cable-stayed bridges with three-dimensional modeling (1997) Computer & Structures, 64 (1-4), pp. 741-758; Simões, L., Negrão, J., Sizing and geometry optimization of cable-stayed bridges (1994) Computer & Structures, 52 (2), pp. 309-321; Simões, L., Negrão, J., Optimization of cable-stayed bridges with box-girder decks (2000) Advances in Engineering Software, 31, pp. 417-423; Ferreira, L., Simoes, L., Optimum design of controlled cable stayed bridge subject to earthquakes (2011) Structure Multidisc Optimization, 44, pp. 517-528; Baldomir, A., Hernandez, S., Nieto, F., Jurado, J., Cable optimization of a long span cable stayed bridge in La Coruña (Spain) (2010) Advances in Engineering Software, 41, pp. 931-938; Lute, V., Upadhyay, A., Singh, K., Genetic algorithms-based optimization of cable stayed bridges (2011) Journal Software Engineering and Applications, 4, pp. 571-578; Wilson, E.L., Kiureghian, A., Bayo, E.P., A replacement for the SRSS method in seismic analysis (1981) Earthquake Engineering and Structural Dynamics, 9, pp. 187-192; Ito, M., Cable-supported steel bridges: Design problems and solutions (1996) Journal of Construction Steel Research, 39, pp. 69-84; Freire, A.M.S., Negrão, J.H.O., Lopes, A.V., Geometrical nonlinearities on the static analysis of highly flexible steel cable-stayed bridges (2006) Computer Structures, 84 (31-32), pp. 2128-2140; Al-Rousan, R., Haddad, R.H., Al Hijaj, M.A., Optimization of the economic practicability of fiber-reinforced polymer (FRP) cable-stayed bridge decks (2014) Bridge Structures, 10 (4), pp. 129-143; Wang, P.H., Tseng, T.C., Yang, C.G., Initial shape of cable-stayed bridges (1993) Journal of Computers Structures, 46, pp. 1095-1106; Abdel-Ghaffar, A.M., Nazmy, A.S., 3-D nonlinear seismic behavior of cable-stayed bridges (1991) J Struct Eng, 117 (11), pp. 3456-3476; Abdel-Ghaffar, A.M., Khalifa, M.A., Importance of cable vibration in dynamics of cable-stayed bridges (1991) J Eng Mech, 117 (11), pp. 2571-2589; Soneji, B.B., Jangid, R.S., Influence of soil-structure interaction on the response of seismically isolated cable-stayed bridge (2008) Soil Dyn Earthq Eng, 28 (4), pp. 245-257; Caetano, E., Cunha, A., Gattulli, V., Lepidi, M., Cable-deck dynamic interactions at the International Guadiana Bridge: On-site measurements and finite element modelling (2008) Struct.

Natta,” Politecnico di Milano, Milan, Italy","Vertebral compression fractures are one of the most relevant clinical consequences caused by osteoporosis: one of the most common treatment for such fractures is vertebral augmentation through minimally invasive approaches (vertebroplasty or balloon-kyphoplasty). Unfortunately, these techniques still present drawbacks, such as re-fractures of the treated vertebral body with subsidence of the non-augmented portions or re-fracture of the non-augmented middle column at the junction with the augmented anterior column. A novel minimally-invasive augmentation technique, called Stent-Screw Assisted Internal Fixation, has been recently proposed for the treatment of severe osteoporotic and neoplastic fractures: this technique uses two vertebral body stents and percutaneous cannulated and fenestrated pedicular screws, through which cement is injected inside the expanded stents to achieve optimal stents’ and vertebral body’s filling. The role of the pedicle screws is to anchor the stents-cement complex to the posterior column, acting as a bridge across the middle column and preserving its integrity from possible collapse. In order to evaluate the potential of the new technique in restoring the load bearing capacity of the anterior and middle spinal columns and in reducing bone strains, a Finite Element model of an osteoporotic lumbar spine has been developed. Both standard vertebroplasty and Stent-Screw Assisted Internal Fixation have been simulated: simulations have been run taking into account everyday activities (standing and flexion) and comparison between the two techniques, in terms of strain distribution on vertebral endplates and posterior and anterior wall, was performed. Results show that Stent-Screw Assisted Internal Fixation significantly decrease the strain distribution on the superior EP and the cortical wall compared to vertebroplasty, possibly reducing the re-fracture risk of the middle-column at the treated level. © 2019 La Barbera, Cianfoni, Ferrari, Distefano, Bonaldi and Villa.","Finite element model (FEM); Osteoporosis; Screw-stent assisted internal fixation (SAIF); Spine biomechanics; Vertebral augmentation; Vertebral compression fractures (VCF)","Bone; Cements; Diseases; Fracture; Musculoskeletal system; Screws; Stents; Strain; Internal fixation; Osteoporosis; Spine biomechanics; Vertebral augmentation; Vertebral compression; Finite element method",,,,,"Fondazione IRCCS Ca' Granda Ospedale Maggiore Policlinico; Fondazione per la Ricerca Biomedica, FORB","This study was supported by Fondazione per la Ricerca Ospedale Maggiore (FROM, Bergamo, Italy).",,,,,,,,,,"Abudou, M., Chen, X., Kong, X., Wu, T., Surgical versus non-surgical treatment for thoracolumbar burst fractures without neurological deficit.

In civil engineering, curved elements are used to model tunnels, arch bridges, pipelines, and domes. Such structures provide a more efficient load transfer than their straight/flat counterparts due to the additional strength provided by their curved geometry. The load transfer is characterized by the bending, shear, and membrane actions. In this paper, a higher-order curved inverse beam element is developed for the inverse Finite Element Method (iFEM), which is aimed at reconstructing the deformed structural shapes based on real-time, in situ strain measurements. The proposed two-node inverse beam element is based on the quintic-degree polynomial shape functions that interpolate the kinematic variables. The element is C2 continuous and has rapid convergence characteristics. To assess the element predictive capabilities, several circular arch structures subjected to static loading are analyzed, under the assumption of linear elasticity and isotropic material behavior. Comparisons between direct FEM and iFEM results are presented. It is demonstrated that the present inverse beam finite element is both efficient and accurate, requiring only a few element subdivisions to reconstruct an accurate displacement field of shallow and deep curved beams. © 2020 by the authors.

The geometrical rail track condition is monitored in real-time using fiber optic sensors, providing early warning if pre-defined thresholds are exceeded in terms of longitudinal, horizontal and cross-level defects. The sensor reading units can be remotely located from the monitored zones, without requiring active elements on the tracks and ensuring high immunity to electromagnetic interference. The proposed technology has been first validated in railway laboratories and then in field trials confirming its capability to detect defects over pre-established thresholds and the absence of false alarms with regular train circulation. © 2000-2011 IEEE.","Bragg grating; finite element analysis; optical fiber sensors; railway engineering; railway safety; Raman scattering","Bridges; Defects; Electromagnetic pulse; Fiber optic sensors; Fiber optics; Fibers; Patient monitoring; Railroad transportation; Railroads; Rails; Temperature sensors; Active elements; Bridges , viaducts; Distributed temperature sensing; Early warning; Railway infrastructure; Railways infrastructures; Sensor readings; Sensor systems; Fiber Bragg gratings",,,,,,,,,,,,,,,,"Bernal, E., Spiryagin, M., Cole, C., Onboard condition monitoring sensors, systems and techniques for freight railway vehicles: A review (2019) Ieee Sensors J., 19 (1), pp. 4-24. , Jan; Jovanović, S., Bovžović, D., Tomivčić-Torlaković, M., Railway infrastructure condition-monitoring and analysis as a basis for maintenance management (2014) Gradevinar, 66 (4), pp. 347-358. , May; Hodge, V.J., O'Keefe, S., Weeks, M., Moulds, A., Wireless sensor networks for condition monitoring in the railway industry: A survey (2015) Ieee Trans.

The free vibration results as well as the deflection results due to a single moving load are compared with previous studies. A finite element MATLAB code is developed to offer an efficient solution for dynamic analysis of stiffened plated structures under single and multiple moving loads in which various types of stiffener are attached to the plate. Some of the example results have been verified with FEAST (Finite Element Analysis of STructures) software to show the efficacy of the method. The parametric study is carried out by attaching various types of stiffeners in the main load carrying direction to find out the maximum deflections under single and multiple moving loads and also for the moving loads passing in opposite directions on the bridge with different velocities. The central deflection due to moving loads on stiffened plates with fixed/floating transverse frames is also analyzed in this paper. © 2020 Institution of Structural Engineers","Bridge stuctures; Dynamic analysis; Finite element method; Moving loads; Stiffened plate",,,,,,,,,,,,,,,,,"Cox, H.L., Boxer, J., Vibration of rectangular plates point-supported at the corners (1960) Aeronaut Q, 11 (1), pp. 41-50; Chen, C.J., Liu, W., Chern, S.M., Vibration analysis of stiffened plates (1994) Comput Struct, 50 (4), pp. 471-480; Lee, H.P., Ng, T.Y., Effects of torsional and bending restraints of intermediate stiffeners on the free vibration of rectangular plates (1995) Mech Struct Mach, 23 (3), pp. 309-320; Barik, M., Mukhopadhyay, M., A new stiffened plate element for the analysis of arbitrary plates (2002) Thin Wall Struct, 40 (7-8), pp. 625-639; Ahmad, N., Kapania, R.K., Free vibration analysis of integrally stiffened plates with plate-strip stiffeners (2016) AIAA J, 54 (3); Nayak, A.N., Satpathy, L., Tripathy, P.K., Free vibration characteristics of stiffened plates (2018) Int J Adv Struct Eng, 10 (2), pp. 153-167; Sahoo, P.R., Barik, M., Free vibration analysis of stiffened plates (2020) J Vib Eng Technol; Wilson, E.N., Tsirk, A., (1967), Dynamic behavior of rectangular plates and cylindrical shells, National Aeronautics and Space Administration Report No. NGR-33-016-067; Raske, T.F., Dynamic response of plates due to moving loads (1967) J Acoust Soc Am, 42 (3), pp. 625-635; Dobyns, A.L., Analysis of simply-supported orthotropic plates subject to static and dynamic loads (1981) AIAA J, 19 (5), pp. 642-650; Wu, J.J., Lee, M., La, T.S., The dynamic analysis of a flat plate under a moving load by the finite element method (1987) Int J Numer Methods Eng, 24 (4), pp. 743-762; Taheri, M.R., Ting, E.C., Dynamic response of plate to moving loads: structural impedance method (1989) Comput Struct, 33 (6), pp. 1379-1393; Taheri, M.R., Ting, E.C., Dynamic response of plates to moving loads: finite element method (1990) Comput Struct, 34 (3), pp. 509-521; Humar, J.L., Kashif, A.H., Dynamic response analysis of slab-type bridges (1995) J Struct Eng, 121 (1), pp. 48-62; Henchi, K., Fafard, M., Dhatt, G., Talbot, M., Dynamic behaviour of multi-span beams under moving loads (1997) J Sound Vib, 199 (1), pp. 33-50; Henchi, J., Fafard, M., Talbot, M., Dhatt, G., An efficient algorithm for dynamic analysis of bridges under moving vehicles using a coupled modal and physical components approach (1998) J Sound Vib, 212 (4), pp. 663-683; Takabatake, H., Dynamic analysis of rectangular plates with stepped thickness subjected to moving loads including additional mass (1998) J Sound Vib, 213 (5), pp. 829-842; Wu, J.J., Whittaker, A.R., Cartmell, M.P., The use of finite element techniques for calculating the dynamic response of structures to moving loads (2000) Comput Struct, 78 (6), pp. 789-799; Sun, L., Dynamic displacement response of beam type structures to moving line loads (2001) Int J Solid Struct, 38 (48-49), pp. 8869-8878; Sasidhar, M.N.V., Talukdar, S., Non-stationary response of bridge due to eccentrically moving vehicles at variable velocity (2003) Adv Struct Eng, 6 (4), pp. 309-324; Wu, J.J., Dynamic analysis of a rectangular plate under a moving line load using scale beams and scaling laws (2005) Comput Struct, 83 (19-20), pp. 1646-1658; Kim, S.H., Cho, K.I., Choi, M.S., Lim, J.Y., Development of a generation method of artificial vehicle wheel load to analyze dynamic behavior of bridges (2009) Adv Struct Eng, 12 (4), pp. 479-501; Song, Q., Shi, J., Liu, Z., Wan, Y., Dynamic analysis of rectangular thin plates of arbitrary boundary conditions under moving loads (2016) Int J Mech Sci, 117, pp. 16-29; Shirmohammadi, F., Bahrami, S., Saadatpour, M.M., Dynamic response of rectangular plate subjected to moving loads using spectral finite strip method (2017) Asian J Civ Eng (BHRC), 18 (5), pp. 703-718; Yang, D.S., Wang, C.M., Pan, W.H., Further insights into moving load problem on inclined beam based on semi-analytical solution (2020) Structures, 26, pp. 247-256; Newmark, N.M., A method of computation for structural dynamics (1959) J Eng Mech Div, 85 (3), pp. 67-94; Mizusawa, T., Kajita, Y., Naruoka, M., Vibration of skew plates by using B-spline functions (1979) J Sound Vib, 62 (2), pp. 301-308; Siddiqui, H.R., Shivhare, V., Free vibration analysis of eccentric and concentric isotropic stiffened plate with orthogonal stiffeners using ansys (2015) Int J Signal Process Image Process Pattern Recognit, 8 (12), pp. 271-284; Khedmati, M.R., Ghavami, K., A numerical assessment of the buckling/ultimate strength characteristics of stiffened aluminium plates with fixed/floating transverse frames (2009) Thin-Wall Struct, 47, pp. 1373-1386","Sahoo, P.R.; Department of Civil Engineering, India; email: prakash.bitu@gmail.com",,,"Elsevier Ltd",,,,,23520124,,,,"English","Structures",Article,"Final","",Scopus,2-s2.0-85092687542

However, existing studies have only discussed the influence of a certain NF characteristic on the seismic response, rather than systematically discussing and comparing the influence of different NF characteristics. Furthermore, current research is only suitable for a specific structure while the influence of NF characteristics on structures with different dynamic characteristics has not been revealed. As an important lifeline project, the safety of a cable-stayed bridge (CSB) during earthquakes is of great concern. Therefore, this paper investigates the influence of NF ground motions on the seismic response of CSB. Firstly, three major characteristics (i.e., the hanging wall effect, rupture directivity effect and high velocity pulse) of NF ground motions are analyzed using NF records of the Chi–Chi earthquake. Secondly, a finite element (FEM) model for modeling a prototype CSB is developed and benchmarked. Then, the seismic responses of the prototype CSB subjected to NF ground motions with different characteristics are analyzed using the benchmarked FEM model. The analyses show that hanging wall effect, rupture directivity effect, and high velocity pulse affect the seismic demand of the CSB to varying degrees. Furthermore, the influences of NF characteristics on the displacement response of CSBs with different fundamental periods are investigated using SDOF systems. The analysis results show that different NF characteristics have various influences on the displacement response of CSBs with different fundamental periods. © 2020, Springer Nature B.V.","Cable-stayed bridge (CSB); Hanging wall effect; NF characteristics; Rupture directivity effect; Velocity pulse","Cable stayed bridges; Cables; Faulting; Seismic response; Displacement response; Dynamic characteristics; Fundamental period; Ground motions; Hanging-wall effects; Near fault ground motion; Rupture directivity; Seismic demands; Earthquakes; bridge; Chi-Chi earthquake 1999; displacement; ground motion; hanging wall; numerical model; rupture; seismic response",,,,,"National Natural Science Foundation of China, NSFC: 51308465, E51508102; China Postdoctoral Science Foundation: 2018M631292; Beijing Postdoctoral Science Foundation: 2018-ZZ-032","This research was supported by: (1) National Science Foundation of China (Award Nos: E51508102, 51308465), (2) Postdoctoral Science Foundation of China (Award No: 2018M631292), (3) Postdoctoral Science Foundation of Beijing (Award No: 2018-ZZ-032).

Public infrastructure networks contain numbers of bridges prone to accidental vehicular impact loading. This paper investigates the response of as-built and carbon fiber reinforced polymers (CFRP)-strengthened bridge piers struck with lightweight and medium-weight vehicles at a city speed limit of 56 km/h, a highway speed limit of 100 km/h, and a police chase speed of 150 km/h. The present study involves the development of three-dimensional (3D) complex nonlinear finite element analysis models of a 13.4 m 3-lane-wide and 7.9 m high AASHTO-LRDF-designed single hammerhead bridge pier. Two publicly available vehicle finite element models representing lightweight and medium-weight trucks were used in the study. An explicit 3D nonlinear finite element software program LS-DYNA was used to simulate vehicle pier collisions. The complete vehicle and single hammerhead bridge pier finite element model had a total of 140,577 elements and finite element analysis was performed at the Ohio Supercomputer Center. Full-scale experimental head-on collision data reported in literature and principles of energy conservation were used to validate the accuracy of the proposed finite element analysis models. Finite element analysis results revealed that CFRP composites contained impact-induced localized damages and peak dynamic impact force surpassed AASHTO design impact force. © 2020 American Society of Civil Engineers.","Bridge pier; Carbon fiber reinforced polymers (CFRP); Explicit finite element analysis; Impact load; LS-DYNA; Vehicle collisions","Bridge piers; Carbon fiber reinforced plastics; Supercomputers; Vehicles; 3D nonlinear finite elements; Carbon fiber reinforced polymer; Finite element analysis model; Head-on collision; Nonlinear finite element analysis model; Public infrastructures; Threedimensional (3-d); Vehicle collisions; Finite element method",,,,,,,,,,,,,,,,"(2003) LRDF Design Example for Steel Girder Superstructure Bridge, , AASHTO.

Based on the simplified model, a novel frequency-domain impedance measurement method based on the two-port network technique is proposed to extract the power loop inductances through direct measurement.

Based on the principle of stationary potential energy, the work derives an analytical expression for a mapping between the vertical deformation of continuous beam structure and rail deformation by considering the effect of the subgrade. Then, the mapping relation between the vertical deformation of various typical bridge structures and rail deformation was calculated using analytical method. The results were compared with those obtained using ANSYS finite element method. The effects of four factors on rail deformation were investigated, namely, pier settlement, staggered steps on girder, rotation angles on beam ends, and number of spans of simply supported beam. The calculation results obtained via analytical method and those obtained using finite element method fit well with each other, verifying the rationality and correctness of the analytical method. The expression for analytical method is concise and can easily obtain the mapping relation between the structural vertical deformation and rail deformation using the displacement boundary conditions. The vertical deformation of the rail was proportional to the vertical deformation of same typical structure. Both inside and outside the rail deformation area, the length of rail deformation section did not change with structural vertical deformation. When there were simply supported beams at both ends of the continuous beam, the number of spans of simply supported beams had no significant effect on the rail deformation caused by the vertical deformation of typical continuous beam structures. When there were no simply supported beams, the settlement of side pier of continuous beam caused rail deformation similar to the staggered step of girder. © 2020","Analytical model; Continuous beam of high-speed railway; CRTS Ι ballastless track; Mapping relation; Principle of stationary potential energy",,,,,,"2019RS3009; National Natural Science Foundation of China, NSFC: 51778630, U1934207; Fundamental Research Funds for Central Universities of the Central South University: 2018zzts189, 502501006","This research was financially supported by the National Natural Science Foundations of China (Grant Number U1934207 and 51778630); the Fundamental Research Funds for the Central Universities of Central South University (Grant Number 2018zzts189 and 502501006), and Hunan Innovative Provincial Construction Project (Grant Number 2019RS3009).","This research was financially supported by the National Natural Science Foundations of China (Grant Number U1934207 and 51778630 ); the Fundamental Research Funds for the Central Universities of Central South University (Grant Number 2018zzts189 and 502501006 ), and Hunan Innovative Provincial Construction Project (Grant Number 2019RS3009 ).",,,,,,,,,"Hu, N., Dai, G., Yan, B., Liu, K., Recent development of design and construction of medium and long span high-speed railway bridges in china (2014) Eng Struct, 74, pp. 233-241; Guo, Y., Zhai, W., Sun, Y., Pei, G., Jiang, J., Mechanical characteristics of modern tramcar-embedded track system due to differential subgrade settlement (2017) Aust J Struct Eng, 18, pp. 178-189; Jiang, L., Zhang, Y., Feng, Y., Zhou, W., Tan, Z., Dynamic response analysis of a simply supported double-beam system under successive moving loads (2019) Appl Sci, 9, p. 2162; Gou, H., Shi, X., Zhou, W., Cui, K., Pu, Q., Dynamic performance of continuous railway bridges: numerical analyses and field tests (2018) Proc Inst Mech Eng Part F-J Rail Rapid Transit, 232, pp. 936-955; Trong-Phuoc, H., Hwang, C., Limongan, A.H., The long-term creep and shrinkage behaviors of green concrete designed for bridge girder using a densified mixture design algorithm (2018) Cem Concr Compos, 87, pp. 79-88; Fahmy, M.F.M., Wu, Z., Wu, G., Sun, Z., Post-yield stiffnesses and residual deformations of rc bridge columns reinforced with ordinary rebars and steel fiber composite bars (2010) Eng Struct, 32, pp. 2969-2983; Toydemir, B., Kocak, A., Sevim, B., Zengin, B., Ambient vibration testing and seismic performance of precast i beam bridges on a high-speed railway line (2017) Steel Compos Struct, 23, pp. 557-570; Mia, M.M., Bhowmick, A.K., A finite element based approach for fatigue life prediction of headed shear studs (2019) Structures, 19, pp. 161-172; Alexander, N.A., Kashani, M.M., Exploring bridge dynamics for ultra-high-speed, hyperloop, trains (2018) Structures, 14, pp. 69-74; Mantawy, I.M., Thonstad, T., Sanders, D.H., Stanton, J.F., Eberhard, M.O., Reinforcing steel fracture identification for a high-performance bridge system (2019) Structures, 19, pp. 58-67; Jiang, L., Feng, Y., Zhou, W., He, B., Vibration characteristic analysis of high-speed railway simply supported beam bridge-track structure system (2019) Steel Compos Struct, 31, pp. 591-600; Domenech, A., Museros, P., Martinez-Rodrigo, M.D., Influence of the vehicle model on the prediction of the maximum bending response of simply-supported bridges under high-speed railway traffic (2014) Eng Struct, 72, pp. 123-139; Gou, H., Zhou, W., Bao, Y., Li, X., Pu, Q., Experimental study on dynamic effects of a long-span railway continuous beam bridge (2018) Appl Sci-Basel, 8; Wang, S., Xu, Z., Li, S., Dyke, S.J., Safety and stability of light-rail train running on multispan bridges with deformation (2016) J Bridge Eng, 21; Chen, Z., Sun, Y., Zhai, W., Mapping relationship between pier settlement and rail deformation of high-speed railways-part (i): the unit slab track system.

However, PSBCs could be severely damaged during an earthquake due to their limited seismic capacity. Rapid repair of the PSBCs and the seismic behavior of the repaired PSBCs are critical to the post-earthquake recovery of bridges with such columns. In this study, an original PSBC specimen is designed, constructed, and tested under cyclic loading. After the cyclic test on the original specimen is carried out, carbon fiber reinforced polymer (CFRP) sheets and sticky steel glue are used to repair the damaged specimen. The repaired PSBC specimen is then tested under the same loading protocol as the original specimen to compare their cyclic performance. Test results show that the concrete damage of the repaired specimen is reduced compared to the original specimen, and the repaired column has a relatively larger energy dissipation and residual displacement than those of the original column. To leverage the test results, detailed three-dimensional finite element models are developed and calibrated with the results from the experiments. Closely replicating the test results, the validated finite element models are used to replace the lab experiments for the parametric modeling of the seismic performance of bridges with PSBCs while capturing effects of CFRP. Specifically, the influence of CFRP design variables, including the CFRP cross-sectional area ratio and the CFRP height ratio, on the seismic performance of the repaired PSBCs is evaluated by using the validated finite element model. It is found that the CFRP cross-sectional area ratio has little effect on the seismic capacity of the repaired PSBCs, and the repaired PSBC with a CFRP height ratio of 2.0 is the most suitable for the repaired PSBCs investigated in this study. © 2020 Elsevier Ltd","CFRP wraps; Precast segmental columns; Quasi-static tests; Resilience; Seismic repair","Carbon fiber reinforced plastics; Cyclic loads; Earthquakes; Energy dissipation; Finite element method; Seismic design; Seismic waves; Steel fibers; Testing; Carbon fiber reinforced polymer sheets; Cross sectional area ratio; Pre-cast; Precast segmental bridge column; Quasi-static tests; Resilience; Seismic repair; Three dimensional finite element model; Repair",,,,,"National Natural Science Foundation of China, NSFC: 51508276; China Scholarship Council, CSC: 201806845051; Six Talent Peaks Project in Jiangsu Province; Project 333 of Jiangsu Province: 2019-JZ-013","The authors would like to acknowledge the financial support from the National Natural Science Foundation of China (Grant No. 51508276 ), the China Scholarship Council (Grant No. 201806845051 ), and the “Six-Talent Peaks” Project of Jiangsu Province (Grant No. 2019-JZ-013 ).","The authors would like to acknowledge the financial support from the National Natural Science Foundation of China (Grant No. 51508276), the China Scholarship Council (Grant No. 201806845051), and the ?Six-Talent Peaks?

The microgripper is based on a double-stair bridge-type mechanism and consists of a bridge-type mechanism for amplifying the input displacement and the integrated parallelogram mechanisms for linearizing the motion at the microgripper jaws. The displacement transmission, amplification, linearization are accomplished in a single-stage. Stiffness modeling is established to characterize the output displacement, the displacement amplification ratio, and the input stiffness of the mechanism. The right-angle flexure hinges are utilized in the displacement amplification and transmission mechanisms to maintain the input stiffness of the mechanism. The structural design of the microgripper is optimized in such a way that a large output displacement can be achieved. Finite element analysis and experiments are conducted on the microgripper to verify the results of the analytical modeling. The proposed microgripper achieves a large output displacement of 543.8 μm with a displacement amplification ratio of 19.3. The experimental results indicate that the microgripper will be able to accommodate a grasping/releasing task. © 2020, Springer-Verlag GmbH Germany, part of Springer Nature.","C ompliant mechanism; Microgripper;

However, it is hard to determine the mechanical properties of this design due to its complex geometries and nonlinear deformation configuration, thereby limiting its further applications. In this paper, we present a model for the postbuckling behavior of kirigami membranes through a combination of theoretical modeling, finite element analysis, and experiments. Scaling laws for elastic stretchability are developed, showing good agreement with numerical results and experimental images. Investigations on the critical height of post array are conducted to ensure the boundary condition of the kirigami membranes in the analytical model. These results can serve as design guidelines for kirigami structures and facilitate their applications in flexible/stretchable electronics.

Most of them were built more than 100 years ago taking into account only gravitational loads during the design phase without any seismic analysis. For this reason, a seismic vulnerability assessment has been appointed asmandatory regular activity from the Italian government in order to define the priority of seismic retrofit interventions. In this study, a multi-span slender masonry bridge considered as the most vulnerable typology of masonry bridges to seismic action will be assessed. Then, the results obtained from three different seismic assessment approaches will be discussed and compared. In particular, two approaches based on different FE modeling and the last one built on rigid blocks analysis are considered. Finally, a detailed 3D finite element analysis allowed representing all the collapse mechanisms (global and local) of the bridges are presented. Simplified approaches, even though cannot describe all the collapse mechanisms of the bridges due to seismic action can lead to reliable results. © 2020 Zampieri, Perboni, Tetougueni and Pellegrino.","Masonry arch bridges; Non-linear kinematic analysis; Non-linear static analysis; Rigid block analysis; Seismic vulnerability",,,,,,,,,,,,,,,,,"Baraldi, D., Reccia, E., Cecchi, A., In plane loaded masonry walls: DEM and FEM/DEM models (2018) A Critical Review.

To address this problem, high-strength steel framed-tube structures with replaceable shear links (HSS-FTS-RSLs) were proposed, which combine the advantages of replaceable shear links and high-strength steel (HSS). This paper presents an experimental research program including three 2/3-scale single-story single-span sub-structure specimens with three types of spandrel beam-to-link connections: bolted end-plate connection, bolted web connection, and bolted splice-plate connection. The global seismic response and replaceability of the specimens were evaluated. Nonlinear finite element models of the specimens were established and validated with the experimental results. Test results demonstrated that the three specimens developed the expected ductile failure of the shear links while the spandrel beams and columns were damage-free, showing excellent energy dissipation and deformation abilities. The usage of HSS effectively maintained the structural components in essentially linear elastic range. The specimen with bolted end-plate connection exhibited a stable hysteretic response and high resistance. This connection type possesses reliable force transmission, convenient construction, no-slippage property, and the shortest replacement time. The connection rotation as a result of bolt slipping and bolt bearing significantly contributed to the total shear link rotation for the specimens with bolted web connection and bolted splice-plate connection. This led to the increased deformation ability and ductility as well as the pinching of hysteretic loops. Post-earthquake recoverability can be achieved as expected. The acceptable residual story drifts θre that allow for easy replacement of the shear links were 0.41%, 0.31%, and 0.42% corresponding to the specimen with bolted end-plate connection, bolted web connection and bolted splice-plate connection, respectively. The detailed finite element models of the test specimens accurately predicted the experimental behavior. © 2020 Elsevier Ltd","Boltd connection; Cyclic behavior; High-strength steel; Replaceability; Shear link; Steel framed-tube","Bolts; Bridge decks; Deformation; Ductility; Earthquakes; Energy dissipation; Finite element method; High speed steel; Hysteresis; Plates (structural components); Boltd connection; Cyclic behavior; Replaceability; Shear link; Steel-framed; High strength steel; accuracy assessment; cyclic loading; dynamic response; earthquake engineering; experimental study; finite element method; seismic design; seismic response; shear strength; steel structure; structural response",,,,,"National Natural Science Foundation of China, NSFC: 51708444; Natural Science Foundation of Shaanxi Province: 2018JQ5074","This work was supported by the National Natural Science Foundation of China [Grant No. 51708444 ] and Shaanxi Natural Science Foundation [Grant No. 2018JQ5074 ].",,,,,,,,,,"Singh, Y., Nagpal, A.K., Negative shear lag in framed-tube buildings (1994) J Struct Eng, 120 (11), pp. 3105-3121; Rahgozar, R., Sharifi, Y., An approximate analysis of combined system of framed tube, shear core and belt truss in high-rise buildings (2009) Struct Des Tall Spec Build, 18 (6), pp. 607-624; Taranath, B.S., Structural analysis and design of tall buildings: steel and composite construction (2016), CRC Press; (2016), ANSI/AISC 358–16.

Due to seismic excitation, liquefied soil layers may result in substantial accumulated permanent deformation of sloping ground near the abutments. Ultimately, global response is dictated by the bridge-ground interaction as an integral system. However, a holistic assessment of such response generally requires a highly demanding full three-dimensional (3D) model of the bridge and surrounding ground. As such, in order to capture a number of the salient involved mechanisms, this study focuses on the longitudinal seismic performance of a simpler idealized configuration, motivated by details of an existing bridge-ground configuration. In this model, a realistic multilayer soil profile is considered with interbedded liquefiable/nonliquefiable strata. The effect of the resulting liquefaction-induced ground deformation is explored. Attention is given to overall deformation of the bridge structure due to lateral spreading in the vicinity of the abutments. The derived insights indicate a need for such global analysis techniques, when addressing the potential hazard of liquefaction and its consequences. © 2020 John Wiley & Sons, Ltd.","bridge; finite element; lateral spreading; liquefaction; seismic; soil-structure interaction","3D modeling; Abutments (bridge); Bridges; Deformation; Finite element method; Liquefaction; Seismology; Soil structure interactions; Soils; Full three-dimensional; Ground deformations; Lateral spreading; Liquefaction induced deformation; Permanent deformations; seismic; Seismic excitations; Seismic Performance; Soil liquefaction; bridge; deformation mechanism; earthquake engineering; liquefaction; seismic response; soil profile; soil-structure interaction; structural response; three-dimensional modeling",,,,,"California Department of Transportation, CT: 65A0548","This research was supported by the California Department of Transportation (Caltrans) under Contract No. 65A0548 with Dr Charles Sikorsky as the project manager.

The results showed that the failure mode of this type is different from that of conventional concrete specimens. During the failure of specimens, there are few cracks and the overall stiffness still maintain a high level, and reveal that a balance between the size of transverse rebar and the diameter of the hole. In addition, the basic form of the ultimate bearing capacity of existing PBL shearing bonds is summarized, and a new concept of steel fiber shearing in UHPC is proposed. Finally, based on the elastic foundation beam model, the full curve calculation formula of UHPC single-hole PBL shear bond is derived by using Timoshenko beam element. The formula calculation results are in good agreement with the experimental values. © 2020, Korean Society of Civil Engineers.","Finite-element analysis; Perfobond rib shear connector; Shear capacity; Timoshenko beam; Ultra high performance concrete","Aggregates; Bridges; Composite structures; Finite element method; Particle beams; Shearing; Shearing machines; Steel fibers; Structure (composition); Ultra-high performance concrete; Elastic foundation beam; Experimental and numerical analysis; Shear capacity; Shear connector; Timoshenko beam elements; Timoshenko beams; Ultimate bearing capacity; Ultra high performance concretes (UHPC); Structural design",,,,,"Nanjing Forestry University, NFU; National College Students Innovation and Entrepreneurship Training Program: 201710298024Z","The authors wish to express their sincere to the Innovation and Entrepreneurship Training Program for Students (201710298024Z) for their financial support.

In order to protect the sea environment and facilitate the sustainable development, a construction method of large cylindrical structures without dredging the intact marine clay was adopted for the first time. The stone column improvement method was used to strengthen the soft seabed soils in this project. However, the large cylindrical structures developed horizontal displacement up to 3–7 m which aroused suspicion of the safety of the artificial island in public. A three-dimensional finite-element method was developed to simulate the construction process of the structures step by step to seek consistency with the prototype. Results show that the horizontal displacement of the large cylindrical structures is 4 m under the design load. The obtained horizontal displacement agrees well with the field measurement. It is found that the earth pressure acting on the structures is a bit different with the Rankin's earth pressure. The load–horizontal displacement curve and earth pressure distribution were obtained considering the stone columns improvement method, which was further compared with the case without any improvement and the sand filling improvement method. The horizontal displacement with stone column improvement under the design load is 4 m, which is a bit smaller than that without any improvement (i.e., 4.8 m). More efficient improvement methods to strengthen the soft marine clay should be explored in the future. © 2020 Elsevier Ltd","Large cylindrical structures; Soft clay; Stone column improvement; Three-dimensional finite element method","Horizontal wells; Offshore structures; Pressure distribution; Retaining walls; Sustainable development; Construction process; Earth pressure distribution; Horizontal displacements; Improvement methods; Large cylindrical structures; Soft clays; Stone column; Three-dimensional finite element method; Finite element method",,,,,"KQJSCX20180328165808449; HESS-1811; National Natural Science Foundation of China, NSFC: 51539008, 51879187, 51979067","Funding: This work was supported by the Natural Science Foundation of China [grant number 51979067 , 51879187 , 51539008 ]; Shenzhen Peacock Technology Innovation Project [grant number KQJSCX20180328165808449 ]; State Key Laboratory of Hydraulic Engineering Simulation and Safety, Tianjin University Open Foundation [grant number HESS-1811 ].",,,,,,,,,,"Hu, Z.N., Xie, Y.L., Wang, J., Challenges and strategies involved in designing and constructing a 6 km immersed tunnel: a case study of the Hong Kong–Zhuhai–Macao bridge (2015) Tunn.

Glass and carbon filaments were overwrapped on the liner with a winding angle of [±11°/90°2]3 to obtain fully overwrapped composite reinforced vessel with non-identical front and back dome endings. The vessels were loaded with increasing internal pressure up to the burst pressure level. The mechanical performances of pressure vessels, (i) fully overwrapped with glass fibers and (ii) with additional two carbon hoop layers on the cylindrical section, were investigated by both experimental and numerical approaches. In numerical approaches, finite element analysis was performed featuring a simple progressive damage model available in ANSYS software package for the composite section. The metal liner was modeled as elastic–plastic material. The results reveal that the finite element model provides a good correlation between experimental and numerical strain results for the vessels, together with the indication of the positive effect on radial deformation of the COPVs due to the composite interlayer hybridization. The constructed model was also able to predict experimental burst pressures within a range of 8%. However, the experimental and finite element analysis results showed that hybridization of hoop layers did not have any significant impact on the burst pressure performance of the vessels. This finding was attributed to the change of load-sharing capacity of composite layers due to the stiffness difference of carbon and glass fibers. © The Author(s) 2019.","ANSYS; burst pressure; Composite overwrapped pressure vessels;

This new concept is based on an operational modal analysis (OMA) technique that uses dynamic displacement reconstructed from measured acceleration. The reconstructed displacement physically suppresses the high-mode components in measured acceleration data and leads to modal participant factors that are sequentially arranged from low- to high-frequency modes. Thus, compared with the conventional approach that utilizes acceleration data, the proposed procedure provides a more reliable and robust damping estimate regardless of the model order selection. Furthermore, the use of reconstructed displacement guarantees the equilibrium of the system all the time. The OMA adopts a natural excitation technique (NExT) combined with an eigensystem realization algorithm (ERA). A finite element method (FEM)-based finite impulse response filter is adopted to reconstruct the dynamic displacement. The effectiveness and accuracy of the proposed approach is demonstrated for low-frequency dominant structures by using the numerical simulation study of a 9-story shear building and an actual field test of a cable-stayed bridge under operation in Korea. These examples allow a comparison of modal damping ratio estimates using reconstructed displacement and accelerations. © 2019 Elsevier Ltd","Ambient vibration test; Cable-stayed bridge; Damping; Displacement; Operational modal analysis; Reconstruction","Cable stayed bridges; Cables; Damping; Image reconstruction; Impulse response; Vibration analysis; Ambient vibration test; Conventional approach; Displacement; Eigensystem realization algorithms; Model-order selection; Natural excitation techniques (NExT); Numerical simulation studies; Operational modal analysis; Modal analysis",,,,,"Ministry of Science, ICT and Future Planning, MSIP; National Research Foundation of Korea, NRF; Ministry of Science ICT and Future Planning, MSIP: 2017R1A2B4008973; Institute of Construction and Environmental Engineering, Seoul National University, ICEE, SNU","This work was supported by a National Research Foundation of Korea (NRF) grant funded by the Korean government (MSIP) (2017R1A2B4008973) through the Integrated Research Institute of Construction and Environmental Engineering at Seoul National University.

Harrisburg, Middletown, PA  17057, United States","In this paper, an analytical algorithm, based on the bilinear resistance model, was proposed to analyze the track-bridge interaction on long-span steel bridges under thermal action. Calculation results show that the proposed algorithm is more accurate than previous analytical algorithms and can achieve nearly the same accuracy as the finite-element method (FEM), but is more efficient than FEM. Based on the algorithm, this paper explained why the longitudinal force (LF) in the middle of the bridges doesn't increase as bridge length increases, then proposed a manual LF calculation formula. Researchers and engineers can use this formula to easily estimate the maximum LF on bridges which have rail expansion devices (REDs). A parametric study was performed. The result shows that LF is not a matter of concern on the bridges with REDs. Besides, the relationships between track resistance distribution, track-bridge relative displacement and boundary conditions were revealed, and the difference between LF on bridge and on embankment were discussed. The outcomes of this paper can be applied to long-span centrosymmetric continuous bridge as well as cable-stayed bridges. © 2019 American Society of Civil Engineers.","Continuous welded rail; High-speed railway; Long-span bridge; Longitudinal rail force; Rail expansion device; Thermal effect; Track-bridge interaction","Cable stayed bridges; Railroad plant and structures; Steel bridges; Thermal effects; Welded steel structures; Continuous welded rails; Expansion devices; High - speed railways; Long-span bridge; Longitudinal rail force; Track-bridge interactions; Railroad transportation",,,,,"2017G006-N; China Scholarship Council, CSC: 201706370112; Fundamental Research Funds for Central Universities of the Central South University: 2017zzts151","This work is supported by the China Railway Corporation (Project No. 2017G006-N), the Fundamental Research Funds for the Central Universities of Central South University (Project No. 2017zzts151), and China Scholarship Council (Fellowship No. 201706370112).

In the current chopping control mode, there exists a particularly uneven temperature distribution on converters due to not only the thermal coupling effects and dissipating boundary conditions, but also the different device losses in the same phase bridge. For the purpose of precise estimation for junction temperature, first, the power loss of converter is accurately calculated by the interpolation method with the help of Simulink and LTspice. Second, the thermal coupling effects and dissipating boundary conditions are analyzed in the three-dimensional finite-element method (FEM) model. According to the step power response extraction, a coupling impedance matrix is used to describe the nonnegligible thermal coupling effects between devices, and the complete heatsink can be decoupled into multiple subdivisions that represent the different heat dissipating boundary conditions. Then, with coupling impedances and subheatsink impedances in series, a compact RC network model can be built for junction temperature estimation. Consequently, analytical investigation in conjunction with FEM simulation and experiment measurements demonstrate the validity of the proposed model. © 1982-2012 IEEE.","Boundary conditions; finite-element method (FEM); junction temperature; switched reluctance motor (SRM); thermal modeling","Boundary conditions; Electric drives; Electric machine theory; Electric motors; Finite element method; Power converters; Temperature distribution; Analytical investigations; Current chopping controls; Half-bridge converters; Junction temperatures; Switched Reluctance Motor; Switched reluctance motor drive system; Thermal model; Three-dimensional finite element method; Reluctance motors",,,,,"2016YFE0132300; BE2018001-3; TD-XNYQC-004","Manuscript received June 14, 2018; revised November 22, 2018 and January 5, 2019; accepted January 23, 2019.

Propagation behaviours of representative fatigue cracks in vertical stiffener web gaps and horizontal gusset plate web gaps were analysed. Finite element models of welds connecting web, vertical stiffener and horizontal gusset plate were built, and the welding residual stresses of such details were analysed. Significant transverse welding residual tensile stresses exist at stiffener web weld toes for web gap details. Residual stress measurements were conducted, and the crack shape and the propagation direction path were basically the same with that in the numerical simulation, indicating that the numerical simulation results were relatively reliable. Furthermore, the welding residual stress fields were considered in the crack propagation analysis models. Representative fatigue cracks at web gaps are Mode I leading mixed-mode cracks of Modes I, II and III. Crack propagation considering welding residual stress has faster propagation rate and is more consistent with fatigue test results. The welding residual stress cannot be ignored for analysis and assessment of distortion-induced fatigue cracks in steel bridges. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.","distortion-induced fatigue; extended finite element method; fatigue crack; numerical fracture mechanics; Steel girder bridge; welding residual stress","Cracks; Data flow analysis; Fatigue crack propagation; Fatigue testing; Finite element method; Numerical methods; Numerical models; Residual stresses; Steel bridges; Welding; Welds; Distortion-induced fatigue; Extended finite element method; Fatigue cracks; Numerical fracture mechanics; Steel girder bridge; Welding residual stress; Fatigue of materials",,,,,"National Natural Science Foundation of China, NSFC: 51078039, 51578073; Chang'an University, CHD: 310821153501; Major State Basic Research Development Program of China: 2015CB057703","The authors wish to acknowledge the financial support provided by National Natural Science Foundation of China (Grant 51578073, 51078039), the Major State Basic Research Development Program of China (973 Program) and Sub-program (Grant 2015CB057703), the Special Fund for Basic Scientific Research of Central Colleges of the P.R.

Furthermore, a verification procedure for curved stiffened panels is proposed that gives a good estimation of the maximum loads obtained from experimental and numerical tests. The procedure is in line with the design methodology of EN 1993-1-5, accounting also for panel curvature. Nine large-scale tests were performed on longitudinally and transversally stiffened plates made of high strength steel, namely S500 and S700. They were subjected to compressive stresses up to collapse. The nine specimens comprised of flat and curved plates that differed in material grade and geometric parameters, such as panel thickness, aspect ratio, size and shape of stiffeners. The effects of different parameters on the plate's resistance to pure compression are discussed. Moreover, a numerical model built in the general-purpose code ABAQUS is presented and verified against the test results regarding initial stiffness, ultimate resistance and failure mode. Numerical simulations (FEA), based on the test panel geometry, the measured initial geometric imperfections and elasto-plastic material characteristics from tensile tests, demonstrate very good agreement with experimental results. © 2019 Elsevier Ltd","Experimental investigation; FEM; Initial imperfections; Steel bridges; Stiffened curved plates; Uniform compression","Aspect ratio; Finite element method; Geometry; Numerical models; Steel bridges; Tensile testing; Curved plates; Elastoplastic materials; Experimental and numerical analysis; Experimental investigations; Initial geometric imperfection; Initial imperfection; Ultimate resistance; Uniform compression; High strength steel",,,,,"RFCS-2015-709782; P2-0158; Javna Agencija za Raziskovalno Dejavnost RS, ARRS","The research was carried out under the financial support from the European Commission's Research Found for Coal and Steel through the research project OUTBURST ( RFCS-2015-709782) and national founds from Slovenian Research Agency ARRS within the project P2-0158 .

However, information that is directly extracted from monitored data is usually susceptible to uncertainties and not reliable enough to be used for structural investigations. Finite element model updating is an accredited framework that reliably identifies structural behavior. Recently, the modular Bayesian approach has emerged as a probabilistic technique in calibrating the finite element model of structures and comprehensively addressing uncertainties. However, few studies have investigated its performance on real structures. In this article, modular Bayesian approach is applied to calibrate the finite element model of a lab-scaled concrete box girder bridge. This study is the first to use the modular Bayesian approach to update the initial finite element model of a real structure for two states—undamaged and damaged conditions—in which the damaged state represents changes in structural parameters as a result of aging or overloading. The application of the modular Bayesian approach in the two states provides an opportunity to examine the performance of the approach with observed evidence. A discrepancy function is used to identify the deviation between the outputs of the experimental and numerical models. To alleviate computational burden, the numerical model and the model discrepancy function are replaced by Gaussian processes. Results indicate a significant reduction in the stiffness of concrete in the damaged state, which is identical to cracks observed on the body of the structure. The discrepancy function reaches satisfying ranges in both states, which implies that the properties of the structure are predicted accurately. Consequently, the proposed methodology contributes to a more reliable judgment about structural safety. © The Author(s) 2019.","Bayesian framework; box Girder bridge; finite element model updating; Gaussian process; structural health monitoring; vibration analysis","Bayesian networks; Box girder bridges; Bridge decks; Concrete bridges; Concretes; Gaussian distribution; Gaussian noise (electronic); Numerical models; Steel bridges; Structural health monitoring; Vibration analysis; Bayesian frameworks; Bayesian model updating; Civil engineering structures; Concrete box girder bridge; Finite-element model updating; Gaussian Processes; Probabilistic technique; Structural investigation; Finite element method",,,,,"Australian Research Council, ARC: DP160101764; Queensland University of Technology, QUT","The first author would like to express his sincere appreciation to Queensland University of Technology (QUT) for the financial support for his research.

Fatigue life was evaluated based on nominal stress method and hot-spot stress method. The results indicated that the length of the longitudinal influence line for detail stress to wheel loads approximately equalled to twice the diaphragm spacing. The wheel loading location of maximum stress was the front wheel of middle-axle group 0.3 m from the diaphragm, and the stress was dominated by in-plane stress. The nominal stress was hard to define at cutout detail for high stress concentration, and the hot-spot stress was preferred to fatigue assessment based on S-N curve of FAT125, also nominal stress should be extracted at the location 5.0 mm from cutout edge. Cutout shape of Highway Bridge in Eurocode was suggested, and diaphragm thickness should not be below 12 mm. The cutout cracking was caused by poor cutout shape, thin diaphragm, high truck traffic volume and overloaded wheel loads, while undesirable fabrication control and large residual stress might also contribute to the cracking. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.","cracking; cutout detail; fatigue; finite element analysis; hot-spot stress; Orthotropic steel deck","Bridge decks; Crack initiation; Cracks; Diaphragms; Finite element method; Front axles; Stress analysis; Suspension bridges; Suspensions (components); Wheels; cutout detail; Diaphragm cutouts; Fatigue assessments; High stress concentration; Hot spot stress; Nominal stress methods; Orthotropic steel decks; Self-anchored suspension bridge; Fatigue of materials",,,,,"201522; National Natural Science Foundation of China, NSFC: 51878269; National Basic Research Program of China (973 Program): 2015CB057701","The authors would like to acknowledge that this work was supported by the National Basic Research Program of China (973 Program) under Grant number 2015CB057701; the National Natural Science Foundation of China under Grant number 51878269; the Communication Science and Technology Project in the Hunan Province of China under Grant number 201522.",,,,,,,,,,"(2014) LRFD bridge design specifications, , 7th ed., Washington, DC: Author, with interims; (2010) Bridge welding code (AASHTO/AWS D1.5M/D1.5, , Washington, DC: Author; Battista, R.C., Pfeil, M.S., Carvalho, E.M.L., Fatigue life estimates for a slender orthotropic steel deck (2008) Steel Construction, 64 (1), pp. 134-143; (2005) Eurocode 3: Design for steel structures, Part 1-9: Fatigue, , CEN, Brussels: European Committee for Standardisation; (2006) Eurocode 3: Design for steel structures, Part2: Steel Bridges, , CEN, Brussels: European Committee for Standardisation; Connor, R., Influence of cutout geometry on stresses at welded rib-to-diaphragm connections in steel orthotropic bridge decks (2004) Transportation Research Record: Journal of the Transportation Research Board, 1892 (1), pp. 78-87; Connor, R.J., Fisher, J.W., Consistent approach to calculating stresses for fatigue design of welded rib-to-web connections in steel orthotropic bridge decks (2006) Journal of Bridge Engineering, 11 (5), pp. 517-525; De Corte, W., Parametric study of floorbeam cutouts for orthotropic bridge decks to determine shape factors (2009) Bridge Structures, 5 (2-3), pp. 75-85; Donato, A., Antonio, G., Fatigue behaviors of cutout at crossbeam of trapezoidal rib orthotropic deck (2008) Proceedings of the 2nd International Orthotropic Bridge Conference, Sacramento, California, USA, pp. 357-369. , Reston, VA: American Society of Civil Engineering, &; Fanjiang, G.N., Ye, Q., Fernandez, O., Taylor, L., Fatigue analysis and design of steel orthotropic deck for Bronx-Whitestone Bridge, New York City (2004) Transportation Research Record: Journal of the Transportation Research Board, 1892 (1), pp. 69-77; (2012) Manual for design, construction, and maintenance of orthotropic steel deck bridges (No. FHWA-IF, pp. 12-027. , Washington, DC: Federal Highway Administration; Fu, Z., Ji, B., Kong, X., Chen, X., Grinding treatment effect on rib-to-roof weld fatigue performance of steel bridge decks (2017) Journal of Constructional Steel Research, 129, pp. 163-170; Hobbacher, A.F., The new IIW recommendations for fatigue assessment of welded joints and components–a comprehensive code recently updated (2009) International Journal of Fatigue, 31 (1), pp. 50-58. , –,. 04.002; (2008) Recommendations for fatigue design of welded joints and components, [IIW-1823-07/XIII-2151r4-07/XV-1254r4-07, , France: International Institute of Welding Paris; Ji, B., Liu, R., Chen, C., Maeno, H., Chen, X., Evaluation on root-deck fatigue of orthotropic steel bridge deck (2013) Journal of Constructional Steel Research, 90 (5), pp. 174-183; Kozy, B.M., Connor, R.J., Paterson, D., Mertz, D.R., Proposed revisions to AASHTO-LRFD bridge design specifications for orthotropic steel deck bridges (2011) Journal of Bridge Engineering, 16 (6), pp. 759-767; Pfeil, M.S., Battista, R.C., Mergulhão, A.J.R., Stress concentration in steel bridge orthotropic decks (2005) Journal of Constructional Steel Research, 61 (8), pp. 1172-1184; Silla Sanchez, J., Noonan, J., Percy, R., (2014), https://www.arrb.com.au/admin/file/content, West Gate Bridge: management of fatigue cracking., Austroads Bridge Conference, 9th, 2014, Sydney, New South Wales, Australia.

One old welded steel bridge and one old riveted steel bridge are taken as examples for structural performance and safety evaluation. A large number of out plan deformation-induced long fatigue cracks were found at the connection plates connecting the bottom flange of end cross-frames and main girders of the two old steel bridges, and serious corrosion damage was found at such details of the old riveted steel bridge. Cold reinforcement techniques of drilling stop holes and bonding and bolting steel plates were adopted to strengthen the old steel bridges. Fracture mechanical models using the short-term monitoring data were established to assess the fatigue lives before and after the reinforcement, considering the coupling effect of fatigue and corrosion, and the evaluation results indicate that corrosion and fatigue coupling is very significant for old steel bridges. Monitoring and evaluation results show that bonding and bolting steel plates leads to about 90% reduction in the maximum tensile stress and about 8 times fatigue lives extension, while drilling stop holes can only temporarily arrest the crack growth. Additionally, the future maintenance strategies recommendations are provided. © 2019, © 2019 International Association for Bridge and Structural Engineering (IABSE).","cold reinforcement; corrosion fatigue; finite element model; out plan deformation-induced fatigue; steel bridges; structural health monitoring","Beams and girders; Boreholes; Corrosion fatigue; Cracks; Deformation; Failure (mechanical); Fatigue damage; Finite element method; Fracture mechanics; Infill drilling; Plates (structural components); Reinforcement; Steel corrosion; Structural health monitoring; Fatigue performance; Fracture mechanical model; Maintenance strategies; Monitoring and evaluations; Reinforcement technique; Riveted steel bridges; Short-term monitoring; Structural performance; Steel bridges",,,,,,,,,,,,,,,,"Wang, C.S., Chen, W.Z., Chen, A.R., Fatigue safety assessment of existing steel bridges in China (2009) Struct.

The usual fatigue assessment approach for riveted joints consists of using the fatigue class 71 S-N curve proposed in Eurocode 3, part 1–9. However, this approach may lead to excessive conservative predictions since it is applied indistinctly for different riveted connection geometries and materials. Riveted joints fatigue classification according to the proposal of Taras and Greiner produce more consistent description of the experimental data rather than the Class 71 S-N curve as proposed in the EC3. Local approaches are an alternative methodology to perform fatigue characterization of any type of joints, made of any material, providing that material fatigue properties are available as well as accurate numerical models of the joints. This paper presents an experimental campaign and a numerical analysis concerning down-scale riveted specimens. The fatigue behaviour of these riveted joints was also modelled using standard and extended finite element methods. The different models produced diverse predictions, depending on the failure modes considered. © 2019 Elsevier Ltd","Extended finite element method; Fatigue assessment; Finite element method; Local approaches; Riveted connection; S-N curves","Crack propagation; Curve fitting; Finite element method; Steel bridges; Extended finite element method; Fatigue assessments; Local approaches; Riveted connections; S-N curve; Fatigue of materials",,,,,"RFSR-CT-2009-00027, RFSR-CT-2015-00025, SFRH/BD/72434/2010, SFRH/BPD/107825/2015; European Commission, EC; Fundação para a Ciência e a Tecnologia, FCT; Instituto Nacional de Ciência e Tecnologia para Excitotoxicidade e Neuroproteção, INCT-EN: UID/ECI/04708/2019; Programa Operacional Temático Factores de Competitividade, POFC; Research Fund for Coal and Steel, RFCS; Institute of Research and Development in Structures and Construction","This work was financially supported by: Project POCI-01-0145-FEDER-007457 - CONSTRUCT - Institute of R&D In Structures and Construction funded by FEDER funds through COMPETE2020 - Programa Operacional Competitividade e Internacionalização (POCI) – and by national funds through FCT - Fundação para a Ciência e a Tecnologia; UID/ECI/04708/2019 - CONSTRUCT - Instituto de I&D em Estruturas e Construções funded by national funds through the FCT/MCTES (PIDDAC); RFCS Project called FADLESS - Fatigue Damage Control and Assessment for Railway Bridges (RFSR-CT-2009-00027); Ph.D. Scholarship (SFRH/BD/72434/2010) provided by FCT to the first author; and post-doctoral grant SFRH/BPD/107825/2015 provided by FCT to the second author.

It was selected as a case study of the FADLESS project, funded by the Research Fund for Coal and Steel [ 2 ]. This riveted bridge was opened to traffic on August 20th of 1956. Its construction was part of an investment project for replacing several bridges in the “Beira Alta” line carried out in the 50's of XX century, under the framework of Marshall Plan. The German House Fried Krupp conceived, manufactured and mounted 6 bridges which led to the demolition of the previous ones built by the Eiffel House. This bridge is a riveted metallic bridge with three spans of 39 m, 48 m and 39 m each, totalizing 126 m in length. The bridge deck is composed by two inverted Warren truss girders of 5.68 m height. The girder panels are 6.50 m wide in the central span and 6.00 m in the end spans. Two trapezoidal shape trusses acting as columns and two granite masonry abutments transmit the loads carried by the structure to the foundation. The bridge has a constant width of 4.40 m throughout its length. In the superstructure bearing supports composed by metallic elements allowing free rotations in the structure plane can be observed. At the east support, the longitudinal displacements are constrained while at the west support deformations caused by longitudinal horizontal forces (thermal actions, braking, etc.) are allowed. The cross girders, as well as the stringers resting on them, were built using “I-shaped” sections. The cross girders have 70 cm height and are connected to the lateral vertical elements with riveted plates as shown in Fig. 1 c). The chords and diagonals of the truss girders are formed by double “U-shape” sections.","Recently, scientific projects have been supported by the European Commission through the Research Fund for Coal and Steel, namely PROLIFE [ 1 ] (Prolonging Life Time of Old Steel and Steel-Concrete Bridges) and FADLESS [ 2 ] (Fatigue Damage Control and Assessment for Railway Bridge) aiming to understand the fatigue behaviour of steel connections and to formulate reliable fatigue-resistant design proposals for structures.",,,,,,,,"Lukic, M., Al-Emrani, M., Aygul, M., Bokesjo, M., Urushadze, S., Fryba, L., Skaloud, M., Pitsolis, A., Bridge Fatigue Guidance - Meeting Sustainable Design and Assessment (2013); Lippi, F., Salvatore, W., Braconi, A., Finetto, M., Wenzel, H., De Roeck, G., Peeters, B., Cunha, A., Fatigue Damage Control and Assessment for Railway Bridge - FADLESS, (Research Fund for Coal and Steel, Directorate-General for Research and Innovation, Grant Agreement RFSR-CT-2009-00027, 1 July 2009 to 30 June 2012); Akesson, B., Fatigue Life of Riveted Steel Bridges (2010), 1st ed CRC Press; Crocetti, R., On some Fatigue Problems Related to Steel Bridges (2001), PhD thesis Chalmers University of Technology Sweden; Mohammad, A., Fatigue in Riveted Railway Bridges (2002), PhD thesis Chalmers University of Technology Sweden; De Jesus, A.M.P., da Silva, A.L.L., Figueiredo, M.V., Correia, J.A.F.O., Ribeiro, A.S., Fernandes, A.A., Strain-life and crack propagation fatigue data from several Portuguese old metallic riveted bridges (2011) Eng.

The procedure, aimed at matching experimental frequencies and mode shapes, allows for fine-tuning the calculations of the free parameters in the model. The numerical method is briefly described, and some issues related to its robustness are addressed. The procedure is then applied to a simple case study and two historical structures in Tuscany, the Clock Tower in Lucca and the Maddalena Bridge in Borgo a Mozzano. © 2019 American Society of Civil Engineers.","Ambient vibration monitoring; Finite-element analysis; Masonry buildings; Model updating","Masonry construction; Masonry materials; Numerical methods; Structural analysis; Vibration analysis; Ambient vibration monitoring; Experimental frequencies; Fine tuning; Finite element codes; Free parameters; Historical structures; Masonry building; Model updating; Finite element method",,,,,"Istituto Nazionale di Alta Matematica ""Francesco Severi"", INdAM; Gruppo Nazionale per il Calcolo Scientifico, GNCS; Ministero dell’Istruzione, dell’Università e della Ricerca, MIUR; Regione Toscana","This research was partially supported by the Region of Tuscany and MIUR, the Italian Ministry of Education, Universities, and Research within the Call FAR-FAS 2014 (MOSCARDO Project: ICT technologies for structural monitoring of age-old constructions based on wireless sensor networks and drones, 2016–2018), and by the GNCS/INdAM project “Metodi numerici avanzati per equazioni e funzioni di matrici con struttura.” These supports are gratefully acknowledged.",,,,,,,,,,"Altunişik, A.C., Okur, F.Y., Fuat Genç, A., Günaydin, M., Adanur, S., Automated model updating of historical masonry structures based on ambient vibration measurements (2018) J.

The test variables considered are the compressive strength of geopolymer concrete (30 MPa and 35 MPa) and the shape of the cross section (square, circular and rectangular). All the glass fibre-reinforced polymer tubes had the same amount of fibres and similar fibre orientation together with the same aspect ratio. The failure of the square and rectangular columns initiated with the splitting of the corners and resulted in a lower load-carrying capacity compared to the circular columns whose failure was initiated by the crushing of glass fibre-reinforced polymer tube followed by the separation of glass fibre-reinforced polymer tube into strips. It can be concluded that axial load-carrying capacity of square and rectangular sections can be improved by a concrete filler with higher compressive strength. Adopted finite element analysis to simulate the behaviour of the columns is capable of predicting the stress–strain behaviour and the mode of failure. © The Author(s) 2019.","confinement; fibre-reinforced polymer column;

In order to address this issue, a 1/6 scale mock-up for the segmental beam of one practical cable-stayed composite bridge was precast and assembled. Long-term performance test of 390 days was performed on the assembled mock-up subjected to sustained loads. Moreover, shrinkage and creep tests were also conducted on concrete prisms for precast slabs and post-pouring joint of the assembled mock-up. Meanwhile, two types of finite element (FE) models were established by using Midas FEA. The first one adopted the proposed analysis strategy considering the influence of concrete age difference between the post-pouring joint and the precast slabs, and the other one adopted the traditional analysis strategy ignoring the influence of the new-old concrete age difference. The experimental results were compared with the numerical results calculated by these two FE models. The FEM results calculated by the proposed model agreed well with the experimental observations, while the traditional model severely underestimated the effect of creep and shrinkage of the post-pouring joint concrete. The effect of the long-term performance of the new-old concrete reduced the value of normal stress in the post-pouring joint, and tensile stress led by the shrinkage difference of the new-old concrete could appear the position adjacent to the post-pouring joint under the condition of insufficient axial force of the assembled concrete deck. Moreover, water curing of the whole concrete deck of the assembled composite beam after casting the concrete of post-pouring joint can reduce the tensile stress of the concrete deck. Much attention should be paid to the influence of concrete age difference between post-pouring joint and precast slabs, during the serviceability behavior analysis of the assembled steel-concrete composite bridge. © 2019 Elsevier Ltd","Age difference; Assembled; Composite beam; Creep; Experimental study; FEM analysis; Shrinkage","Composite beams and girders; Composite bridges; Creep; Finite element method; Microalloyed steel; Mockups; Precast concrete; Tensile stress; Age differences; Assembled; Composite beam; Experimental study; FEM analysis; Shrinkage",,,,,"National Natural Science Foundation of China, NSFC: 51378501, 51578547, 51778628; Fundamental Research Funds for the Central Universities; Fundamental Research Funds for Central Universities of the Central South University: 2018zzts184","This work was supported by the National Natural Science Foundation of China (grant numbers 51378501, 51578547 and 51778628) and the Fundamental Research Funds for the Central Universities of Central South University (grant number 2018zzts184).

This paper proposes an analytical method for the in-plane nonlinear elastic buckling and post-buckling of pin-ended parabolic multi-span continuous arches. There are four key parts in the proposed method. Firstly, the in-plane nonlinear equilibrium differential equations of each arch were derived based on the strain expression in the Cartesian coordinate system of non-circular arches and the virtual work principle. Secondly, the nonlinear equilibrium equation of continuous arches was proposed based on the deformation compatibility condition of each arch end, and three key coefficients were obtained. Thirdly, the buckling requirements were deduced according to the force balance condition in each arch end. Lastly, analytical solutions for buckling and post-buckling predictions were derived. Comparisons with the results of finite element method, including the load-displacement curve, buckling behavior and buckling predictions, demonstrate that the proposed analytical solution is equipped with high accuracy. The results of theoretical and parametric analysis show that the deformation shape of symmetric and asymmetric buckling of multi-span continuous arches is thoroughly different from the single arches, the mechanical effect of the unloaded arches is a nonlinear horizontal spring support acting on the loaded arch, and the stability parameter ratio has a significant influence on the buckling behavior of multi-span continuous arches. © 2019","Deformation compatibility condition; Force balance condition; Multi-span continuous arches; Nonlinear equilibrium equation; Parabola","Arches; Deformation; Differential equations; Nonlinear equations; Plates (structural components); Deformation compatibility; Force balances; Multi-spans; Non-linear equilibrium equation; Parabola; Arch bridges; analytical method; arch; bridge; deformation; displacement; elasticity; loading; strain",,,,,"National Natural Science Foundation of China, NSFC: 11772129, 51568020; China Scholarship Council, CSC: 201608360147; 5511 Science and Technology Innovation Talent Project of Jiangxi Province: 20141BBG70089","This work was financially supported by National Natural Science Foundation of China (No. 51568020 , No. 11772129 ), China Scholarship Council (No. 201608360147 ) and Science and Technology Plan in Jiangxi Province , China ( 20141BBG70089 ).","This work was financially supported by National Natural Science Foundation of China (No. 51568020, No. 11772129), China Scholarship Council (No. 201608360147) and Science and Technology Plan in Jiangxi Province, China (20141BBG70089).",,,,,,,,,"Jin, C., Jin, H., Reliability-based optimization of steel truss arch bridges (2017) Int J Steel Struct, 17, pp. 1415-1425; Chen, B.C., Wang, T.L., Overview of concrete filled steel tube arch bridges in China (2009) J Pract Period Struct Design Constr, ASCE, 14, pp. 70-80; Zheng, J.L., Wang, J.J., Concrete-filled steel tube arch bridges in China (2018) Engineering, 4, pp. 143-155; Serrano-Lopez, R., Urruchi-Rojo, J.R., Martinez-Martinez, J.A., The shallow arch: a step towards bridges styling in the early 19th century (2018) Eng Struct, 167, pp. 84-95; Timoshenko, S.P., Gere, J.M., Theory of elastic stability (1963), McGraw-Hill International Book Company; Simitses, G.J., An introduction to the elastic stability of structures (1976), Prentice-Hall Englewood Cliffs, N.

To reduce the tensile stress and control the crack width of the reinforced concrete (RC) slab, a new type of connector, called the uplift-restricted and slip-permitted (URSP) connector has been proposed and successfully applied in the area subjected to a negative bending moment in steel-concrete composite bridges. The feasibility of the URSP connector in steel-concrete composite frame buildings is investigated in this study based on a comprehensive parametric analysis. The effects of URSP connectors on the cracking behavior, as well as the stiffness and strength of composite frames, are systematically analyzed using an elaborate finite element model, which resembles a typical composite beam-column joint subjected to both lateral loads and vertical loads. In addition, an optimized arrangement length of URSP connectors is proposed for practical design. The research findings indicate that the application of URSP connectors greatly improves the crack resistance of RC slabs without an obvious reduction of the ultimate capacity and lateral stiffness of the composite frame. It is recommended that the distribution length of URSP connectors at each beam end should be 20-25% of the frame beam length. © 2019 by the authors.","Cracking performance; Distribution length; Finite element analysis; Steel-concrete composite frame; Uplift-restricted and slip-permitted connector",,,,,,"2018YFC0705704","Funding: This research was supported by the National Key Research Program of China (Grant No. 2018YFC0705704) and Key Research Program of China Railway Corp.

The typical solution is to use compliant orthogonal displacement amplification mechanism (such as bridge-type mechanism), in which the flexure hinges are generally axial load-dominated, whereas the deflection of traditional straight-axis flexure hinges is not related to the axial load under small deflection assumption. In this study, a bridge-type mechanism with circular-axis leaf-type (CALT) flexure hinges is designed, analyzed and validated. Through modeling the generalized displacements of CALT flexure hinge, the positive direction of its axis in the bridge-type mechanism is designed. The precise models of load relations for the CALT flexure hinges in the bridge-type DAM are established, and the multi-objective parametric optimization is further given. Small deflection-based static FEA results verify the generalized displacements’ models of CALT flexure hinge as well as the parametric optimization result. Compared with the corresponding bridge-type mechanism with the largest output displacement in the traditional researches, the output displacement of optimal result is improved effectively. For the design validation, the optimal design result is further applied to construct a piezoelectric-driven microgripper, which grasps parallelly and enlarges the output stroke simultaneously. © 2018, Springer-Verlag GmbH Germany, part of Springer Nature.",,"Axial loads; Bridges; Compliant mechanisms; Bridge-type mechanisms; Design validation; Displacement amplification mechanisms; Flexible manipulations; Generalized displacements; Parametric optimization; Piezoelectric-driven; Small deflection; Hinges",,,,,"2015AG10018; National Natural Science Foundation of China, NSFC: 51705076; Natural Science Foundation of Guangdong Province: 2015A030310181, 2016A030313481; Foshan University, FOSU: Gg07092; Science and Technology Planning Project of Guangdong Province: 2015B010101015","Acknowledgements This research is supported by the National Natural Science Foundation of China (Grant 51705076), the Natural Science Foundation of Guangdong Province (Grant nos. 2016A030313481, 2015A030310181), the Science and Technology Planning Project of Guangdong Province (Grant no. 2015B010101015), the Scientific and Technological Innovation Special Funding of Foshan (Grant no. 2015AG10018), the High-Level Talent’s Research Funding of Foshan University (Grant no.

Hybridization of less expensive basalt fibres with carbon fibres leads to more sustainable alternative to Basalt-FRP (BFRP) bars and more economically-efficient alternative to Carbon-FRP (CFRP) bars. The New-Developed HFRP bars were subjected to tensile axial loading to investigate its structural behaviour. The effect of hybridization on tensile properties of HFRP bars was verified experimentally by comparing the results of tensile test of HFRP bars with non-hybrid BFRP bars. It is worth to mention that the difference in obtained strength characteristics between analytical and numerical considerations was very small, however the obtained results were much higher than results obtained experimentally. Authors suggested that lower results obtained experimentally can be explained by imperfect interphase development and therefore attempted to improve the chemical cohesion between constituents by adding nanosilica particles to matrix consistency. © 2019 E.D.

Its conservation state is initially investigated by means of a thorough field and laboratory test campaign, comprising destructive and non-destructive tests. Two different methods are used to evaluate the bridge seismic vulnerability. The first method adopts a deterministic approach and corresponds to a single non-linear static analysis, performed as described in the Eurocodes. The second method employs a probabilistic approach and considers the variability of the involved mechanical parameters (structure geometry and properties of the building materials) and seismic parameters (intensity of the action and site conditions). This method associates the probabilistic values of ground acceleration exceedance to the estimated seismic vulnerability. This is shown by means of fragility curves, which allow to take into consideration the uncertainty of the various components involved in the definition of the seismic vulnerability and display the seismic damage scenarios. Currently no code requires to perform this calculation procedure. In addition, this work compares the values of masonry mechanical properties specified in the Eurocodes with those obtained in an extensive investigation campaign involving more than one hundred masonry bridges. Compressive strength and longitudinal elasticity modulus are the relevant mechanical parameters investigated. The outcomes of this research can contribute to the development of a more efficient maintenance system of the masonry bridges belonging to the railway network. This has an important role when it comes to establishing the priority order of assets intervention. © 2018 The Author","Bridge maintenance and conservation; Finite element analysis; Masonry mechanical parameters; Non-linear static analysis; Railway masonry arch bridge; Seismic fragility","Arches; Codes (standards); Compressive strength; Finite element method; Masonry bridges; Masonry construction; Masonry materials; Nondestructive examination; Railroads; Seismology; Static analysis; Structural analysis; Bridge maintenance; Masonry arch bridges; Mechanical parameters; Non-linear static analysis; Seismic fragility; Arch bridges",,,,,"Sapienza Università di Roma","This work was supported by a collaboration between Sapienza University of Rome and Standard Infrastructure Civil and Experimental , Italian Railway Network (RFI) .",,,,,,,,,,"Achenbach, J., (1984) Wave Propagation in Elastic Solids, 16. , North Holland Amsterdam; Aki, K., Richards, P., Quantitative Seismology (1980), first ed.

Instead, these systems and their connections are designed on a case-by-case basis by either conducting necessary testing or adopting the design criteria/procedures developed primarily for cast-in-place concrete deck systems. Shear pocket connections formed using steel hollow structural sections (HSS) provide a promising solution to connecting precast concrete deck panels to the supporting girders due to their superior structural performance and simplicity of panel fabrication. The main objective of this paper is to develop criteria/procedures for designing HSS formed shear pocket connections in full-depth precast concrete deck systems. These procedures will assist bridge designers in selecting pocket dimensions, HSS thickness, pocket anchorage and reinforcement necessary to maximize the connection capacity while allowing adequate construction tolerance. Experimental investigation (push-off testing) and finite element analysis (FEA) were performed to validate the developed design criteria/procedures. Analysis and testing results indicated that the developed design criteria/procedures for HSS formed shear pocket connections are satisfactory. © 2018 Elsevier Ltd","Bridges; Composite section; Full-depth deck panel; Precast; Shear pocket connection","Bridges; Cast in place concrete; Pile driving; Shear flow; Composite sections; Construction tolerance; Deck panel; Experimental investigations; Hollow structural sections; Pre-cast; Precast concrete deck; Structural performance; Precast concrete; bridge; composite; concrete structure; design",,,,,,,,,,,,,,,,"(2011), Accelerated bridge construction manual - experience in design, fabrication and erection of prefabricated bridge elements and systems.

In this paper, a master S-N curve-based fatigue life assessment approach for the welded joint with an open-rib in orthotropic steel bridge deck is proposed based on the finite element model (FEM) and field monitoring data from structural health monitoring (SHM) system. The case studies on fatigue life assessment by use of finite element analysis (FEA) for constant-Amplitude cyclic loading mode and field monitoring data under variable-Amplitude cyclic loading mode are addressed. In the case of FEA, the distribution of structural stress at fatigue-prone weld toe is achieved using 4-node shell element model and then transformed into equivalent structural stress by fracture mechanics theory. The fatigue life of the welded joint is estimated with a single master S-N curve in the form of equivalent structural stress range versus the cycles to failure. In the case of monitoring data-based fatigue life assessment, the daily history of structural stress at diaphragm to U-rib is derived from the raw strain data measured by the instrumented fiber Bragg grating (FBG) sensors and transformed into equivalent structural stress. The fatigue life of the investigated welded joint is calculated by cyclic counting method and Palmgren-Miner linear damage cumulative rule. The master S-N curve method provides an effective fatigue life assessment process, especially when the nominal stress is hard to be defined. A single master S-N curve will facilitate to solve the difficulty in choosing a proper S-N curve which is required in the traditional fatigue life assessment methods. © 2019 World Scientific Publishing Company.","fatigue life assessment; finite element analysis; master S-N curve method; Steel bridge; structural health monitoring; welded joint","Cyclic loads; Fiber Bragg gratings; Finite element method; Fracture mechanics; Monitoring; Steel bridges; Stresses; Structural health monitoring; Welded steel structures; Welding; Welds; Curve method; Fatigue life assessment; Fiber Bragg Grating Sensors; Field monitoring data; Fracture mechanics theory; Orthotropic steel bridge decks; Structural health monitoring (SHM); Variable amplitudes; Fatigue of materials",,,,,"National Natural Science Foundation of China, NSFC: 51778574; Ministry of Education, MOE; Harbin Institute of Technology, HIT; National Key Research and Development Program of China, NKRDPC: 2017YFC0806100; Fundamental Research Funds for the Central Universities: 2017QNA4024","The work described in this paper was jointly supported by the National Key R&D Program of China (Grant No. 2017YFC0806100), the National Science Foundation of China (Grant No. 51778574), the Fundamental Research Funds for the Central Universities of China (Grant No. 2017QNA4024), and the Key Lab of Structures Dynamic Behavior and Control (Harbin Institute of Technology), Ministry of Education, Harbin 150090, China.",,,,,,,,,,"Fisher, J.W., (1984) Fatigue and Fracture in Steel Bridges: Case Studies, , Wiley New York; Stephens, R.I., Fatemi, A., Stephens, R.R., Fuchs, H.O., (2001) Metal Fatigue in Engineering, , Wiley, New York; Ye, X.W., Ni, Y.Q., Wong, K.Y., Ko, J.M., Statistical analysis of stress spectra for fatigue life assessment of steel bridges with structural health monitoring data (2012) Eng Struct, 45, pp. 166-176; (1980) BSI BS5400: Steel, Concrete and Composite Bridges, Part 10: Code of Practice for Fatigue, , British Standards Institution, London; (1992), CEN.

The feasibility and method of performing shaking table tests are examined using a simplified half-bridge scale model. By taking advantage of the symmetry, it is possible to construct a scale model with a larger scale ratio than a full-bridge scale model. The main components of the scale model (i.e. tower, piers, girder, and cables) were fabricated using the same or similar materials as in the prototype. The design and construction of the scale model is presented. Longitudinal structural responses obtained from the finite element analysis and shaking table tests are compared.

Thus, the assumption commonly used in practical assessment that multi-span masonry viaducts behave as a series of independent single-span structures, may not be realistic for many configurations. While several experimental and numerical studies have been conducted to investigate single-span masonry arches and bridges, only limited research has been devoted to the analysis of the response of multi-span masonry bridges. This study investigates numerically masonry arch bridges with multiple spans subjected to vertical loading. For this purpose, an advanced finite element description, which is based upon a mesoscale representation for masonry and accounts for both material and geometric nonlinearities, is employed to shed some light on the actual behaviour of these structural systems. A validation study is first carried out to confirm that the adopted modelling strategy is capable to accurately simulate previous experimental results. Then, the influence of some critical geometrical and mechanical parameters that affect the bridge response is evaluated through a parametric study. The effects of pier settlements and brickwork defects are also investigated, as well as the interaction between adjacent spans through comparisons against the response of single-span counterparts. © 2020 Elsevier Ltd","Backfill; Masonry arch bridges; Mesoscale model; Multi-span","Arches; Masonry bridges; Masonry construction; Masonry materials; Piers; Traffic surveys; Experimental and numerical studies; Geometric non-linearity; Masonry arch bridges; Mechanical parameters; Mesoscale analysis; Modelling strategies; Structural systems; Vertical loadings; Arch bridges; arch; backfill; bridge; finite element method; geometry; loading; masonry; road traffic; structural analysis; structural response",,,,,"European Commission, EC: 657007","The financial support of the European Commission through the Marie Skłodowska-Curie Individual fellowship IF (“FRAMAB”, Grant Agreement 657007) for the first author is greatly acknowledged.

In this paper, the shear fracture evolution and failure mechanism of rock-like materials containing cross-flaws are first reported based on a developed CZM-FEM method. The laboratory uniaxial compression and corresponding numerical tests were initially performed to acquire the mechanical parameters of rock-like materials. Subsequently, the direct shear test of rock-like materials containing two sets of cross-flaws was conducted, the effect of the main flaw and secondary flaw angles were considered. At last, the mechanical properties and fracture behaviors, and the coalescence mechanism were investigated and concluded. The results indicate that four typical stages are observed during the shearing process of rock-like materials with cross-flaws, which are the linear elastic stage, crack strengthening stage, plastic softening stage, and residual strength stage, respectively. Note that the mechanical properties (i.e., peak, residual shear strength, and the crack initiation stress) and cracking behaviors are strongly dependent on the angles of the main and secondary flaws as well as the loading conditions (i.e., shear rates and constant applied normal stresses). In addition, the coalescence mechanism of rock bridge between the two cross-flaws can be classified into three types, which are the mixed shear tensile-tensile damage, shear-tensile damage, and tensile damage, respectively; Similarly, the coalescence paths can also be identified as three types, respectively, the connection between the main flaw and the secondary flaw, linkage by the two main flaws, and the penetration dominated by the coalescence of the main flaw and the secondary flaw. © 2020 Elsevier Ltd","Cohesive elements; Cross-flaws; CZM-FEM; Fracture evolution; Rock bridge","Coalescence; Cracks; Fracture; Shear flow; Shear strength; Shearing; Shearing machines; Stress analysis; Coalescence mechanisms; Linear elastic stages; Mechanical parameters; Plastic softening; Residual shear strength; Rock like materials; Underground tunnels; Uni-axial compression; Rocks",,,,,"Natural Science Foundation of Shandong Province: ZR2019BEE065","This research was funded by Shandong Provincial Natural Science Foundation, China (Grant No. ZR2019BEE065).",,,,,,,,,,"Wang, D.J., Tang, H.M., Derek, E., Wang, C.Y., Fracture evolution in artificial bedded rocks containing a structural flaw under uniaxial compression (2019) Eng.

Super-Resolution (SR) serves as a bridge to harmonize the need and demand. Recently, Convolutional Neural Network (CNN) based networks have demonstrated great property in image SR. However, most existing methods require large model capacity and consume expensive computation for high performance. Besides, most methods keep the upscaling part relatively simple compared with the feature extraction part. For feature fusion, some methods directly concatenate the features of multi-levels, which is suboptimal due to ignoring the importance of different features. In this work, we propose a recursive multi-stage upscaling network (RMUN) with multiple sub-upscaling modules (SUMs) and a discriminative self-ensemble module (SEM). Specifically, we extract local hierarchical features by using a novel feature extraction module (FEM) which is recursive to reduce the number of parameters. Then, we construct multiple sub-upscaling modules to produce various high-resolution features in forward propagation. This strategy enhances the upscaling part and provides multiple error feedback routes. Furthermore, we employ an SEM for global hierarchical feature recalibration, which can selectively emphasize informative features and surpass less useful ones. Extensive quantitative and qualitative evaluations on benchmark datasets show that our proposed method performs comparable with the state-of-the-art methods in terms of the balance of model size and model performance. © 1963-12012 IEEE.","Convolutional neural networks; discriminative fusion; self-ensemble; super-resolution","Backpropagation; Benchmarking; Convolution; Convolutional neural networks; Extraction; Feature extraction; Optical resolving power; Display technologies; Forward propagation; Hierarchical features; Multi-stage upscaling; Qualitative evaluations; self-ensemble; State-of-the-art methods; Super resolution; Deep learning",,,,,"MCM20190701; National Natural Science Foundation of China, NSFC: 61671077; Fundamental Research Funds for the Central Universities: 2019PTB-011","Manuscript received October 11, 2019; revised January 21, 2020; accepted February 3, 2020.

Building information modeling (BIM) is a technique used to federate essential data on engineering knowledge regarding cable-supported bridges. In this study, a BIM-based master digital model that uses a data-driven design for multiple purposes is proposed. Information requirements and common data environments are defined considering international BIM standards. A digital inventory for a suspension bridge is created using individual algorithm-based models, and an alignment-based algorithm is used to systematize them and generate the entire bridge system. After assembling the geometrical model, metadata and various BIM applications are linked to create the federated master model, from which the mechanical model is derived for further stages. During the construction stage, the advantage of this digital model lies in its capability to perform efficient revisions and updates with respect to varying situations during the erection process. Stability analyses of the bridge system can be performed continuously at each erection step while considering the geometric control simulation. Furthermore, finite element analysis models for any individual structural member can be extracted from the master digital model, which is aimed at estimating the actual behavior of bridge members. In addition, a pilot master digital model was generated and applied to an existing suspension bridge; this model exhibited significant potential in terms of bridge data generation and manipulation. © 2020 by the authors.

To overcome these limitations, we proposed a new analysis framework that integrates the meshfree analysis method into the Industry Foundation Classes (IFC)-based bridge model. We added the IFC entities to manage information for the bridge structures and meshfree analysis based on the IFC extension concept. We developed modules for generating the bridge model based on the proposed schema. The data required for meshfree analysis were presented through the extraction and conversion process from the IFC model. Finally, the proposed framework was applied to the stress analysis of the bridge structure to demonstrate the efficiency of the method. As a result, we confirmed the possibility of seamless information exchange and interoperability between the architectural and structural analysis models. © 2020 Elsevier B.V.","Building Information Modeling (BIM); IFC extension; IFC-based bridge model; IFC-based meshfree analysis; Industry Foundation Classes (IFC); Meshfree analysis","Architectural design; Stress analysis; Analysis frameworks; Building Information Model - BIM; Conversion process; Industry Foundation Classes - IFC; Information exchanges; Manage information; Meshfree analysis; Meshfree collocation; Information management",,,,,"Ministry of Education, MOE: 2016R1A6A3A11934917; National Research Foundation of Korea, NRF","This research was supported by Basic Science Research Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Education ( 2016R1A6A3A11934917 ).",,,,,,,,,,"Messner, J., Anumba, C., Dubler, C., Goodman, S., Kasprzak, C., Kreider, R., Leicht, R., Zikic, N., BIM Project Execution Planning Guide, Version 2.2, Computer Integrated Construction Research Program (2019), https://www.bim.psu.edu/bim_pep_guide/4, The Pennsylvania State University (Accessed 22 June 2020); Sanguinetti, P., Abdelmohsen, S., Lee, J., Lee, J., Sheward, H., Eastman, C.M., General system architecture for BIM: an integrated approach for design and analysis (2012) Adv.

The bridge, named Azzone Visconti bridge, was built in the 14th century and is placed in northern Italy. The bridge behaviour under static loads was checked by means of a sequence of acceptance load tests designed accordingly to the provisions of the Italian Code. A detailed 3D finite element model was built based on previous extensive geometric survey, historical data and mechanical characterization of both the soil constituting the riverbed and the stone masonry constituting the piers. Three different models describing the mechanical behaviour of the foundations have been implemented to include soil-structure interaction. A comparison between the experimental measures obtained during the acceptance load tests and the numerical results has allowed establishing the reliability of the models. Post-test nonlinear finite element analyses have allowed the evaluation of the bridge mechanical behaviour under vertical static loads. The influence of the different soil-structure interaction models adopted in the analyses on the evaluation of the bridge structural response is widely discussed. © 2020 Elsevier Ltd","3D FE model; Bearing capacity; Masonry arch bridge; On-site bearing load test; Soil-structure interaction (SSI)","Acceptance tests; Arches; Finite element method; Load testing; Masonry bridges; Masonry construction; Masonry materials; Soil structure interactions; Soils; 3D finite element model; Experimental and numerical studies; Masonry arch bridges; Mechanical behaviour; Mechanical characterizations; Non-linear finite-element analysis; Soil compressibilities; Three dimensional modelling; Arch bridges; compressibility; dynamic response; loading; masonry; soil dynamics; soil mechanics; soil-structure interaction; structural response; three-dimensional modeling; Italy",,,,,,"The Authors are in debt with the Municipality of Lecco and “Consorzio dell'Adda” for the precious historical and technical documents acquired with their help and with Arch.

Carbon and glass fiber reinforced polymer (FRP) bars are getting attention as an alternative to steel bars to enhance the overall performance of the concrete bridge deck slabs and minimize corrosion-induced deteriorations. This study presents a 3D nonlinear finite element analysis (NLFEA) simulating the response of full-scale concrete bridge deck slabs reinforced with FRP bars. A control slab model was developed initially and properly calibrated and validated against published independent experimental results. A parametric study was then conducted through creating 27 NLFEA models with different parameters: concrete compressive strength, reinforcement type (glass FRP, carbon FRP, and steel), and bottom transverse reinforcement ratio. Monotonic single concentrated load was applied at the center of the concrete deck slab over a contact area of 600 mm × 250 mm, simulating the footprint of sustained truck wheel load. The CFRP and GFRP bars reinforcement of bridge deck slabs had superior effects on the ultimate load, elastic stiffness, post cracking stiffness, elastic energy absorption and post cracking energy and a little impact on ultimate deflection compared with steel reinforcement. Punching shear failure with a very similar cracking pattern was observed almost in all slabs and the bottom transverse reinforcement ratio is the main parameter affecting the tensile strains. For all slabs reinforced with GFRP and CFRP bars, the maximum measured strains in the bars at failure were less than 50% of their ultimate strain. Increasing concrete compressive strength will increase the ultimate load capacity and corresponding deflection of the slab. © 2020 Institution of Structural Engineers","Bridge deck slabs; CFRP bars; GFRP bars; NLFEA",,,,,,"Jordan University of Science and Technology, JUST","The authors acknowledge the technical support provided by Jordan University of Science and Technology.",,,,,,,,,,"Yunovich, M., Thompson, N.G., Corrosion of highway bridges: Economic impact and Control methodologies (2003) Concr Int, 25 (1), pp. 52-57; (2006), Intelligent Sensing for Innovative Structures (ISIS).

The paper proposes a numerical model to analyse a coupled vehicle–bridge–soil system, taking into account the most important phenomena affecting the structure, while at the same time being comparatively computationally efficient. Such model is useful in the early design phases of a project, when analysing a range of possible configurations or conducting parametric analysis is required. A simplified vehicle model, nonlinear wheel–rail interaction, a bridge structure modelled using the finite-element method and a semi-analytical model for layered soil are all introduced in the model. A pure time-domain solution procedure is used, utilizing lumped-parameter models (LPMs) for the soil–foundation system. Representation of the dynamic stiffness matrix using LPMs is investigated by analysing the cross-coupling between footings and a novel procedure necessary for computationally stable LPMs is introduced and utilized. Further, pure time-domain solution is compared with an iterative mixed-domain solution. Finally, to illustrate the capabilities of the model, analyses are carried out to determine the resulting maximum and minimum excitation limits resulting from wheel–rail interaction on a number of randomly generated uneven track profiles. © 2020 Elsevier Ltd","High-speed railways; Lumped-parameter models; Multi-degree-of-freedom vehicle; Railway bridge; Soil–structure interaction; Wheel–rail interaction","Iterative methods; Soils; Stiffness matrix; Time domain analysis; Vehicles; Wheels; Computationally efficient; Dynamic stiffness matrix; Early design phasis; Foundation systems; Lumped parameter models; Parametric -analysis; Semi-analytical model; Time domain solution; Lumped parameter networks",,,,,"Interreg; European Regional Development Fund, ERDF","The research was carried out in the framework of the project “Urban Tranquillity” under the Interreg V programme.

A three-dimensional (3D) finite element (FE) model is built and a bond-slip model is incorporated into the simulation of interfacial bond between FRP and concrete. To validate the accuracy of the numerical model, experimental results from 42 dynamic single shear tests on FRP-concrete joints are employed. The debonding load and shear slip responses, FRP strain distributions, and interfacial bond-slip responses are compared between the numerical and experimental results. It is found that the numerical model is capable of predicting the debonding behaviours under various loading rates. In addition, an analytical dynamic bond strength model is proposed to predict the ultimate debonding strain and debonding load by incorporating the dynamic increase factor and strain rate. In addition, a semi-empirical model is proposed to predict the ultimate debonding strain and debonding load by incorporating the dynamic increase factor and strain rate. The semi-empirical model is validated against the numerical results and 119 experimental tests with a good correlation. © 2020 Elsevier Ltd","Finite element modelling; FRP-concrete interface; Interfacial bond; Strain rate","Bridge decks; Cladding (coating); Debonding; Fiber bonding; Fiber reinforced plastics; Forecasting; Numerical models; Polymer concrete; Reinforced concrete; Reinforcement; Strain rate; Analytical dynamics; Dynamic increase factor; Fibre reinforced polymers; Finite element codes; Finite element modelling; Numerical results; Semi-empirical modeling; Threedimensional (3-d); Finite element method",,,,,"Australian Research Council, ARC","The authors would like to acknowledge the financial support from the Australian Research Council .",,,,,,,,,,"Hao, H., Li, Z.-X., Shi, Y., Reliability analysis of RC columns and frame with FRP strengthening subjected to explosive loads (2015) J.

This is mainly to help engineers and researchers to better understand the behavior of BGST bridges during seismic excitations. Within this backdrop, this study fills the gaps in the current knowledge of assessing the combined effect of strong motion duration and spectral shape on the response of bridges using a comprehensive set of numerical simulations and statistical analyses. Three-dimensional finite element models of two real BGST bridges are analyzed using a large set of ground motions obtained from crustal sources and subduction sources. By means of Step-wise regression – and other statistical procedures – the sensitivity of bridge response parameters to various ground motion parameters including Arias Intensity (Ia), RotD50 spectral acceleration at the bridge's first natural period (Sa(T1)), Significant Duration (D5-95), mid-frequency (f), the derivative of the mid-frequency (f’) and time at 30% of cumulated Arias Intensity (tmid) are evaluated. Results indicate that in the case of ground motions arising from shallow crustal sources, Ia and Sa(T1) are the best predictors of the bridge response, and strong motion duration (D5-95) has no statistically meaningful impact on the response of bridges. However, it is observed that the D5-95 of the ground motions ascending from the subduction sources highly affects the bridge response; utilizing D5-95 alongside Sa(T1), or Ia, can significantly increase the accuracy of bridge response estimates. Hence, it is concluded that D5-95 is not an important ground motion intensity measure for ground motion selection for bridges located in areas with crustal earthquakes. In contrast, D5-95 is important in subduction zone ground motions and must be given proper consideration in the design and analysis of BGST bridges. © 2020 Elsevier Ltd","Crustal sources; Ordinary Box-Girder Seat-Type (BGST) bridges; Sensitivity analysis; Strong motion duration; Subduction sources","Earthquake effects; Statistical methods; Ground motion intensity measures; Ground motion parameters; Ground motion selections; Spectral acceleration; Stepwise regression; Strong motion duration; Subduction earthquakes; Three dimensional finite element model; Box girder bridges; bridge; computer simulation; earthquake engineering; finite element method; modeling; numerical model; regression analysis; seismic design; sensitivity analysis; statistical analysis; strong motion; subduction; United States; Anas",,,,,"California Department of Transportation, CT: 65A0647","This study is based on work supported by the California Department of Transportation (Caltrans) under Award No. 65A0647 .

The paper presents all research stages of bridge construction and considers the conclusions drawn from the results of laboratory tests, field measurements, and numerical calculations. The monitored structure is the largest extradosed bridge in Europe in terms of the span's length. Due to the considerable size and duration of the investment, it was beneficial to use an alternative method for estimating the compressive strength of concrete based on the maturity function. The bridge sections were investigated in three stages: in summer, autumn, and early spring (in June, September, and March). The monitoring of in-place concrete provided information on the actual temperature of the concrete and its gradients. Based on recorded temperatures and proposed numerical procedures, the actual strength of the cast-in-place concrete and the optimal dates of prestressing were determined. This contributed to shortening the work cycle and speeding up the work schedule. © 2020 The Authors","Augmented maturity method; Cast-in-place concrete; Early-age compressive strength; Extradosed bridge; Numerical simulations; Temperature of concrete","Bridge decks; Cast in place concrete; Compressive strength; Numerical methods; Numerical models; Actual temperature; Bridge constructions; Compressive strength of concrete; Extradosed bridge; Field measurement; Numerical calculation; Numerical procedures; Temperature monitoring; High performance concrete",,,,,,,,,,,,,,,,"Carino, N.J., Lew, H.S., The maturity method: from theory to application (2001) Proceedings of the Structures Congress & Exposition, May 21–23, Washington, D.C., , American Society of Civil Engineers Reston, Virginia; Freiesleben Hansen, P., Pedersen, E.J., Curing of Concrete Structures.

Different from previous methods based on classical continuum mechanics, the PD model does not require additional criteria to guide the growth of crack or damage. In particular, the influence of fatigue threshold value was considered in a systematic formula, and the response surface method was utilized to analyze fatigue failure probability. The proposed model was applied to complex fatigue phenomena such as spontaneous crack nucleation, crack branching, and fatigue failure under biaxial cyclic loadings where fatigue crack paths interact in complicated ways. The fatigue crack growth pattern, fatigue life, and fatigue reliability of specimens considering the biaxial or uniaxial fatigue loadings were analyzed. The accuracy of the fatigue model was verified through a series of comparisons with the experimental, analytical, and FEM results. The effectiveness of the proposed method was also demonstrated in the application to the fatigue reliability analysis of the Ting Kau Bridge. © 2020","Biaxial loading; Fatigue crack; Peridynamics; Reliability; Steel bridge","Continuum mechanics; Cracks; Fatigue crack propagation; Reliability analysis; Reliability theory; Steel bridges; Biaxial cyclic loading; Crack nucleation; Fatigue crack paths; Fatigue performance; Fatigue reliability; Fatigue threshold; Peridynamic theories; Response surface method; Fatigue of materials",,,,,"Hunan Provincial Innovation Foundation for Postgraduate: CX2018B221","Support for this work from Hunan Provincial Innovation Foundation for Postgraduate ( CX2018B221 ) is gratefully acknowledged.",,,,,,,,,,"Imam, B.M., Righiniotis, T.D., Fatigue evaluation of riveted railway bridges through global and local analysis (2010) Constr Steel Res, 66 (11), pp. 1411-1421; Helmerich, R., Kühn, B., Nussbaumer, A., Assessment of existing steel structures.

While varying concrete strength, amount of longitudinal reinforcing steel, and gravity load, the effect of applying an externally bonded steel fiber reinforced polymer (SFRP) wrapping was assessed. The presented approach uniquely quantifies column blast resistance in terms of charge weight. It was found that blast capacity was roughly linearly related to concrete strength and steel reinforcement ratio, the former of which is most influential. It was further found that a single layer of SFRP modestly increased blast resistance, while additional SFRP layers provided minimal benefit. © 2020 American Society of Civil Engineers.","Blast; Bridges; Columns; Concrete; Explosive load; Fiber reinforced polymer (FRP); Finite element analysis; Steel fiber reinforced polymer (SFRP)","Bridges; Fiber reinforced concrete; Fiber reinforced plastics; Steel fibers; Concrete strength; Externally bonded; Fiber reinforced polymers; Gravity loads; Material damages; Non-linear finite elements; Quantitative resistance; Steel reinforcements; Blast resistance",,,,,,,,,,,,,,,,"(2017) LRFD bridge design specifications, , AASHTO. 8th ed.

In order to support the structural assessment of concrete bridges better, a procedure has been proposed, based on successively improving the bridge analysis. A multilevel strategy for structural analysis has been combined with concepts for verification of the desired safety margin, thus providing tools for engineers to model the structural behavior of bridges more accurately when necessary. This paper describes the procedure as applied to a prestressed concrete girder bridge, with use of experiences from the previous failure tests and associated evaluations of the bridge. Initial structural assessment indicated the critical failure mode to be due to shear in one of the girders; however, the enhanced analysis showed a complex failure involving both the girder and the bridge deck slab. Improving the structural analysis using nonlinear FE analysis for the loading initially identified as critical, increased the permitted axle loads on the bridge to 12 to 14 times those given by traditional and standardized assessment methods, depending on the concept used for safety verification. The model uncertainty was crucial for the verification of the structural safety and has to be properly taken into account. However, there are few recommendations, with regard to model uncertainties, on the application of nonlinear FE analysis, and detailed guidelines should be used for the modeling procedure in order to reduce analyst-dependent variability in the results. The presented study demonstrates the applicability and the advantages of using the proposed procedure for successively improved analysis for bridge assessment. © 2019 fib.

In this procedure are incorporated three different creep constitutive relations, two recommended by national codes such as the ACI (North-American) and EC2 (European) building codes and one by the RILEM research association. The approximate expressions of the different creep functions with the corresponding Dirichlet series are generated using the continuous retardation spectrum approach based on the Post-Widder formula. The proposed rate-type formulation is implemented into a 3D finite element code and applied to study the long-term deflections of a prestressed concrete bridge built in Romania, which crosses a wide artificial channel that connects the Danube river to the port of Constanta in the Black Sea. © 2020 by the authors.","Concrete creep; Concrete shrinkage; Long-term behavior; Prestressed box girder bridge; Prestressed concrete; Tridimensional FEM analysis",,,,,,,"This research was funded by Italrom Inginerie Internationala S.r.l.

At this time, riveted construction was the method used for building up members and for the connection of one member to another. In this paper, field measurements were performed to find the actual dimension of an existing old riveted steel bridge (El-Ministerly Bridge, Egypt). The inspection of the steel bridge did not find any clear cracks. Finite element models were created to predict the response of the steel bridge. The finite element model was used to identify the location of the stress concentration. A static field test was performed using a 49-ton truck to evaluate actual strain measurements in different locations over the bridge. The strain measurement was used to validate the finite element model while was able to predict the experimental data closely. As an application of the use of the finite element model, evaluate the bridge was executed using AASHTO standards, Egyptian code (ECP) and S–N curves from the literature. It was observed that all stress ranges for this bridge were less than the ECP limits (Fsr) and the estimated remaining fatigue life is about 11 years if it is environmentally protected. © 2020, Springer-Verlag GmbH Germany, part of Springer Nature.","Field-testing; Finite element method; Riveted bridges","AASHTO standards; Automobile testing; Electric measuring bridges; Finite element method; Steel testing; Strain measurement; Egyptians; Field measurement; Field testing; Remaining fatigue life; Riveted steel bridges; Static fields; Stress range; Twentieth century; Steel bridges",,,,,,,,,,,,,,,,"Kulak, G.L., Smith, L., Analysis and design of fabricated steel structures for fatigue: A primer for civil engineers (1993) Structural Engineering Report, (190); Peter, J.M., (1995) Fatigue Tests of Riveted Bridge Girders, , M.Sc.

Static load test was carried out to determine the live load distribution factor (DF) and load-rating factor (RF) as well as serviceability by means of deflection limits. Modal characteristics in terms of structural frequencies and mode shapes and impact factor (IM) were identified from the dynamic load test for different truck-load and speed cases, and finite element (FE) model. The DF and rating factor (RF) were also compared with those calculated according to AASHTO standard and FE model. The results showed that the DF calculated by American Association of State Highway and Transportation Officials (AASHTO) standard gave more conservative results when compared with the experimental and FEM approaches. Similarly, the load-rating factor (RF) calculated by AASHTO standard yielded to more conservative results comparing with the experimental FEM approaches using practical DFs. Maximum deflections in static cases and dynamic cases were found to be within the limit calculated by (L/800) given in the AASHTO code. Impact factors among all the cases were obtained much smaller than the one recommended by AASHTO standard (33%). The modal properties were obtained to track changes in dynamic behavior due to stiffness and boundary effects as well as for finite element model calibration. The calibrated FE model of the bridge also indicated that the load carrying capacity of the bridge is adequate after repair. Finally, the results from the current study reveal that use of experimental data can be utilized to obtain load rating with minimum interruption to bridge operations through computer vision technology and methods. © Copyright © 2020 Dong, Bas, Debees, Alver and Catbas.","concrete bridge; distribution factor (DF); impact factor (IM); load rating (RF); load testing; modal characteristics",,,,,,"Türkiye Bilimsel ve Teknolojik Araştırma Kurumu, TÜBİTAK: 2219","The authors would like to acknowledge the input and field support by Mr. Manny Cabrera, PE throughout the study.

To this end, drift demand model as a fundamental ingredient of any probabilistic decision-making analyses is initially developed in terms of the two most common intensity measures, i.e., PGA and Sa (T1). Developing a probabilistic demand model requires a reliable database that is established in this paper by performing incremental dynamic analysis (IDA) under a set of 20 ground motion records. Next, by employing Bayesian statistical inference drift demand models are developed based on pre-collapse data obtained from IDA. Then, the accuracy and reasonability of the developed models are investigated by plotting diagnosis graphs. This graphical analysis demonstrates probabilistic demand model developed in terms of PGA is more reliable. Afterward, fragility curves according to PGA based-demand model are developed. © 2020 Techno-Press, Ltd.","Bayesian Interface; Finite Element Modeling (FEM); Fragility Function Methodology; Probabilistic Seismic Demand Analysis (PSDA)",,,,,,"South Carolina Department of Transportation, SCDOT: SPR 739","This research is partially supported by the South Carolina Department of Transportation (SCDOT) under Project SPR 739.",,,,,,,,,,"Alam, J., Kim, D., Choi, B., Uncertainty reduction of seismic fragility of intake tower using Bayesian Inference and Markov Chain Monte Carlo simulation (2017) Struct.

The following results were obtained. (a) The failure modes of the screw connectors underwent ductile failure caused by pressure deformation and tearing failure of the sheathing panels, and a few specimens experienced brittle failure caused by shearing-off of self-drilling screws. (b) The increase in the end distance or edge distance has less influence on the shear resistance of the screw connectors if either of them exceeds 15 mm. Besides, the increase in spacing of screws has less effect on the shear resistance of the screw connectors if the spacing of screws exceeds 100 mm. The thickness of the gypsum board did not have a distinct effect on the shear resistance of screw connectors. The diameter of the screws, thickness of the steel sheets and thickness of the studs had a significant effect on the shear resistance of screw connectors. (c) Two kinds of failure modes existed for the screw connectors obtained by the finite element simulation, namely, the shearing failure and the combination failure of bearing and tilting. The simulated failure modes were consistent with the experimental results, and the simulated load-displacement curves were close to the experimental results, which indicated the effectiveness of the finite element simulation method. © 2019 Elsevier Ltd","CFS shear wall; Gypsum board; Screw connectors; Shear performance; Steel sheet","Bridge decks; Failure modes; Finite element method; Gypsum; Infill drilling; Shear flow; Shear walls; Shearing; Shearing machines; Steel sheet; Failure of bearings; Finite element simulations; Gypsum board; Load-displacement curve; Monotonic loading; Pressure deformation; Shear performance; Shear resistances; Self drilling screws",,,,,"National Natural Science Foundation of China, NSFC: 51538002, 51978151; Priority Academic Program Development of Jiangsu Higher Education Institutions, PAPD: CE02-2-5; Scientific Research Foundation of the Graduate School of Southeast University: YBPY1963","This research was financially supported by the National Natural Science Foundation of China (Grant numbers: 51978151 , 51538002 ), the Scientific Research Foundation of Graduate School of Southeast University (Grant numbers: YBPY1963 ), and the Priority Academic Program Development of the Jiangsu Higher Education Institutions (Grant numbers: CE02-2-5 ).",,,,,,,,,,"Landolfo, R., Lightweight steel framed systems in seismic areas: current achievements and future challenges (2019) Thin-Walled Struct., 140, pp. 114-131; Peck, Q., Rogers, N., Serrette, R., Cold-formed steel framed gypsum shear walls: in-plane response (2012) J.

The latter contribution, typically neglected for shallow and pile foundations, should be considered for caisson foundations, much more massive and rigid than the foundation soil. In this paper, the inertial forces acting in caisson foundations during seismic shaking are extracted from the results of a parametric study where different caissons supporting bridge piers are subjected to severe ground motions. The parametric study was carried out in the time domain via 3D Finite Element (FE) dynamic analyses performed in terms of effective stresses but assuming an undrained response of the foundation soil. Non-linear and inelastic soil behaviour was described in the analyses by an elastic-plastic constitutive model with isotropic hardening. In the framework of a pseudo-static approach, the caisson inertia is represented by equivalent horizontal and rotational seismic coefficients, kh eq and krot eq, relating the generalised inertial forces to the caisson weight. The coefficient kh eq turns out to be always remarkably smaller than the maximum value computed at ground surface in free-field conditions, kh max (g.s.). The equivalent seismic coefficients kh eq and krot eq are expressed via empirical relationships as a function of the dynamic properties of the whole system and the seismic input, through dimensionless parameters. Calculation examples are finally given, where safety assessment of bearing capacity is made for different systems using the pseudo-static approach, showing that use of the seismic coefficients computed by the proposed relationships yields results consistent with the ones obtained from the dynamic analyses. © 2019 Elsevier Ltd","3D dynamic analyses; Bearing capacity; Bridge piers; Caisson foundations; Horizontal seismic coefficient; Pseudo-static approach; Rotational seismic coefficient; Soil-structure interaction","Bearing capacity; Bridge piers; Caissons; Elastoplasticity; Piles; Pressure vessels; Seismology; Soil structure interactions; Soils; Underwater foundations; 3-D dynamic analysis; Caisson foundations; Dimensionless parameters; Empirical relationships; Free field conditions; Isotropic hardenings; Pseudostatic; Seismic coefficient; Time domain analysis; bearing capacity; bridge; caisson; dynamic analysis; finite element method; foundation; ground motion; inertia; pier; seismic response; soil-structure interaction",,,,,"Dipartimento della Protezione Civile, Presidenza del Consiglio dei Ministri, DPC","The Authors would like to sincerely thank Prof. L.

Further, based on the Hamilton principle, the vibration differential equation and boundary conditions for CBBCW have been deduced. Finally, an IAM for calculating the dynamic characteristics of CBBCW was proposed. Based on the IAM developed in this study, the natural frequencies of multiple CBBCW cases with different spans, shear connection degrees and boundary conditions have been calculated. The results calculated by the IAM have been compared with those calculated by the finite element method and by the general beam theory. The comparison verifies the effectiveness of the IAM and obtains some conclusions that are meaningful to engineering design, i.e. the shear lag effect of CBBCW increases with increasing shear connection degree and also increases with increasing order of the vibration mode, the shear lag effect of the CBBCW is up to 6.2% in the first five orders of the vibration modes and the effect cannot be ignored. In the first- and second-order vibration modes of the CBBCW cases, the maximum interface slip effect of CBBCW is 28.42% and therefore cannot be ignored. On the other hand, the shear lag effect of CBBCW is usually lower than those of ordinary composite box beam with the same web thickness. © 2019, Korean Society of Steel Construction.","Analytical method; Composite box beam with corrugated webs; Dynamic characteristic; Interface slip; Shear lag","Boundary conditions; Box girder bridges; Fiber optic sensors; Analytical method; Box beam; Dynamic characteristics; Interface slip; Shear lag; Shear flow",,,,,"51778630; Fundamental Research Funds for Central Universities of the Central South University: 2018zzts189","The authors would like to thank the anonymous reviewers for their valuable comments and suggestions to improve the quality of the paper.

At present, for the study of vehicle–bridge coupling, it is difficult to reflect the mechanical response characteristics of the bridge pavement because the bridge pavement (road) is often considered as a load. In order to get closer to reality, we use the whole vehicle model and the bridge model to realize the dynamic coupling of highway vehicle–bridge. Moreover, the vehicle model can take into account tire characteristics, such as various linear and nonlinear suspension characteristics, and tire–ground contact characteristics. So, a new vehicle–road–bridge interaction method with higher computational efficiency is proposed. This method can be used not only to analyze the overall mechanical response of bridge structure such as deflection and stress but also to analyze the dynamic characteristics of driving vehicles and the coupling force between tires and pavement and then to analyze the dynamic deformation and stress of asphalt pavement layers on the bridge. First, according to the construction drawings of a steel–concrete bridge on a highway and a Dongfeng brand three-axle vehicle, a vehicle–road–bridge interaction rigid–flexible coupling model was established. Second, the correctness and effectiveness of the vehicle–road–bridge interaction model were verified by field testing. Finally, the dynamic response of the vehicle–road–bridge interaction rigid–flexible coupling model was analyzed. © The Author(s) 2019.","coupling model; dynamics; finite element; numerical simulation;

This paper summarized and selected highly relevant in-site photos of the collapsed bridge, carried out in-depth comparison and FE assessment. The authors discussed the initial crushed region in the concrete truss girder and concluded the reason of the accident. Firstly an investigation based on available photos, videos and other resources eliminated the possibility of failure in the joints and members including 9-10-deck, 10-11-canopy, 12-canopy, 11th member and the deck wherein. Secondly, FE numerical simulation showed, due to the difference on temporary hinges assigned on both ends of 1st member and 12th member, unwanted excessive bending moment appeared in the lower end of 11th and 12th members due to self-weight of the girder in simple-supported state after its placement finished. Resulted greater stress than tensile strength of concrete caused visible initial cracking. The re-tension operation on prestressing rods per the bridge design plans produced additional loading on the diagonal members and thus shear failure of 11-12-deck joint along the penetrated cracking on lower side of 11-deck joint, which was demonstrated by FE model employed by the initial cracking with the pattern shown in NTSB's investigation report. © 2019 Elsevier Ltd","ABC; Collapse; Concrete; Construction; Design; FIU pedestrian bridge; Investigation","Concrete beams and girders; Concretes; Construction; Design; Tensile strength; Bridge design; Collapse; FE model; Florida International University; Investigation; Self-weight; Shear failure; Strength of concrete; Footbridges; bending; bridge; collapse; comparative study; concrete structure; construction; design; finite element method; pedestrian; Florida [United States]; United States",,,,,"National Natural Science Foundation of China, NSFC: 51508053; National Key Research and Development Program of China, NKRDPC: 2016YFC0701202","This paper was sponsored by National Key Research and Development Program of China ( 2016YFC0701202 ) and project supported by National Natural Science Foundation of China ( 51508053 ), which were greatly appreciated by the authors.",,,,,,,,,,"(2015), MCM+FIGG Design-Build Team.

Most applied steel type in the composite piers are H-shaped steel and steel pipe, while seldom research or practice is associated with angle steel. This paper conducted parametric study on the composite column with equal-leg angle steel and aimed to investigate the ultimate load and displacement ductility of the composite columns with different parameters. The parameters include the type of shear connector (stud and perfobond connectors), the type of structural steel (H-shaped steel and angle steel), steel-plate hooping ratio, shear-span ratio, and axial compression ratio. Finite element analysis was conducted for each specimen, which incorporated the concrete confinement effect, as well as the inelastic behavior of concrete, structural steel, and longitudinal and transverse steel bars. The equal-leg angle steel composite column was found to have slightly higher strength and displacement ductility than H-shaped steel composite column. The increase of steel-plate hooping result in larger strength and displacement ductility for the composite column, and the increase of shear-span ratio and axial compression ratio decrease the displacement ductility. Research results suggest stud and perfobond shear connectors should be applied as axial compression ratio being larger than 0.2 and 0.3, respectively.

However, the asymmetric saturation in the bridges will cause the asymmetry distribution of the magnetic potential on the rotor surface, which will bring challenges to the accurate calculation of inductances. Excited by the armature current at different initial phase angles, the flux distributions in the bridges are analyzed. Meanwhile, the reason why the asymmetric saturation exists in the bridges is revealed theoretically. Based on the above analysis, the rotor magnetic potential (RMP) model for an IPM machine with the bridges is established and used to calculate the armature reaction magnetic field and inductances of the IPM machine. In this paper, the RMP distribution in the bridges is obtained by considering asymmetric saturation, so the RMP model can reflect the rotor surface magnetic potential distribution more accurately, which is evident from the adjacent degree between the calculation results and the finite-element analysis (FEA) ones. © 2019 IEEE.","Asymmetrical saturation of the bridges; inductance calculation; interior permanent magnet (IPM) machine; rotor magnetic potential (RMP)","Electric machinery; Inductance; Magnetism; Accurate calculations; Armature reaction; Calculation results; Flux distributions; Inductance calculation; Interior permanent magnet machine; Magnetic potentials; Permanent magnets (pm); Permanent magnets",,,,,"National Natural Science Foundation of China, NSFC: 51690183; Fundamental Research Funds for the Central Universities: 2019QNA4031","ACKNOWLEDGMENT This work was supported in part by the Major Program of National Natural Science Foundation of China under Grant 51690183 and in part by the Fundamental Research Funds for the Central Universities of China under Grant 2019QNA4031.",,,,,,,,,,"Xia, C., Guo, L., Zhang, Z., Shi, T., Wang, H., Optimal designing of permanent magnet cavity to reduce iron loss of interior permanent magnet machine (2015) IEEE Trans.

Paul Research Center at Whittier School, Lincoln, NE  68583, United States","Bridge designs are routinely developed using simplified 1D approximations of structural behavior and assume linear elastic behavior throughout the structure. More rigorous methods can reveal significant unquantified reserve capacity with 3D system behavior as ductile members experience yielding, but reserve capacity can be overestimated if cracking in a concrete deck is neglected. The primary objective of this study is to characterize the influence of concrete deck nonlinearity on 3D system behavior and capacity of skewed steel girder bridges. Structural behavior is examined throughout the range of potential applied loads, from initial linear elastic behavior to initial yielding and ultimate conditions. Additionally, this study provides a secondary benefit by comparing the applicability of two general load distribution characterization methods: response fractions (displacement, strain, or curvature ratios) versus extracted and integrated results from a rigorous analytical model. Analytical models, accounting for material inelasticity in the steel girders, are constructed for each of two experimentally tested bridges. Skew is varied parametrically from 0° to 60°. Concrete deck is modeled with a tension cracking stress limit consistent with typical design assumptions in United States practice. Results are also presented for the 60° case with linear elastic deck to directly compare the influence of cracking versus non-cracking deck. The analyses indicated that neglecting concrete cracking noticably affected capacity by overestimating slab plate flexure between abutments, resulting in increasingly unconservative reserve capacity evaluations with increasing skew. Bridges with small skews evaluated using only elastic analysis were found to be reasonably well characterized using response fractions feasibly obtained from diagnostic load tests. However, bridges with high skews and bridges evaluated using ultimate capacity from detailed finite element analysis, regardless of skew, will receive unnecessarily conservative flexural capacity ratings if response fractions are relied upon to represent analogous internal load effects. © 2019 Elsevier Ltd","Composite steel girder bridges; Concrete cracking; Inelasticity; Load distribution; Nonlinear finite element analysis (NLFEA); Skew; Ultimate capacity","Analytical models; Concretes; Electric power plant loads; Load testing; Plate girder bridges; Steel beams and girders; Composite steel; Concrete cracking; Inelasticity; Load distributions; Non-linear finite-element analysis; Skew; Ultimate capacity; Finite element method; bearing capacity; bridge construction; concrete; cracking (fracture); elasticity; finite element method; flexure; loading; nonlinearity; skewness",,,,,"University of Nebraska-Lincoln, UNL; Office of Research and Economic Development, University of Nebraska-Lincoln","This research was supported by startup funds provided by the College of Engineering and the Office of Research and Economic Development at the University of Nebraska-Lincoln.

However, girders with trapezoidal corrugated webs are susceptible to fatigue under inevitable repeated heavy traffic loads. This paper conducted a large-scale fatigue test of an inclined I-girder with corrugated web under four-point bending, given the scant fatigue test data for this kind of girder and the inadequate validation of relevant fatigue detail category (FAT). Test results show that the critical crack initiated in combined bending-shear region, though multi-cracks initiated at weld toe of the web-to-flange welded detail in constant moment region. The test girder failed almost simultaneously as the critical crack propagated through the flange plate thickness and extended to one side of the flange plate edge. The other two less critical cracks in the constant moment region approximate to be fatal in the final stage of crack propagation. The fatigue failure criterion of the test girder, therefore, is conservatively recommended as the worst case of two conditions, namely the critical crack reaches 1.6 times of flange plate thickness in length or propagates through flange plate thickness. The parametric finite element analysis (FEA) was also conducted to investigate the influence of the corrugation parameters on the stress conditions at fatigue sensitive spot. The FEA results indicate that the shear force prompted the transfer of the location of critical crack from the constant moment region to the combined bending-shear region, and shortened the fatigue life of test girder by 11.3%. In general, the evaluation results indicate that FAT of the web-to-flange welded detail under four-point bending can be recommended as FAT 90 for nominal stress approach, FAT 120 for structural hot spot stress approach and FAT 225 for effective notch stress approach. © 2019 Elsevier Ltd","Corrugated web girders; Effective notch stress; Fatigue test; Life assessment; Welded detail","composite; concrete structure; failure analysis; fatigue; finite element method; stress field; structural analysis; structural component; testing method",,,,,"Fundamental Research Funds for the Central Universities: 2018CDJSK03XK01","The research is supported by the Fundamental Research Funds for the Central Universities (Project No.2018CDJSK03XK01).",,,,,,,,,,"Heywood, P., Corrugated box-girder web lowers bridge weight and cost (1987) Eng News Rec, 219 (25), p. 32; Elkawas, A.A., Hassanein, M.F., El-Boghdadi, M.H., https://doi.org/10.1016/j.engstruct.2016.12.044, Numerical investigation on the nonlinear shear behaviour of high-strength steel tapered corrugated web bridge girders.

The serviceability evaluation of a rail fastening system on a slab track at railway bridge ends is based on the assumption that the stiffness of the rail fastening system is linear. The behavior of the rail fastening system on slab track at the railway bridge ends is studied in detail in this study. In the experimental model, the abutment and pier of the railway bridge were considered to be directly connected to two H-beams through a rail and rail fastening systems. A stiffness model of the rail fastening system for the finite-element analysis was established by performing a clamping-force test. In the finite-element analysis, the rail fastening system was considered as both linear and nonlinear stiffness models. The experimental and numerical results were very similar when the rail fastening system was considered as the nonlinear stiffness model. With the same uplift force acting on the rail fastening system, the displacement results of the nonlinear stiffness model were larger than those of the linear stiffness model. Therefore, it is necessary to employ the nonlinear behavior of the rail fastening system and investigate a displacement-based design method of the rail fastening system when evaluating the serviceability of the rail fastening system on the slab track at railway bridge ends. © 2019","Nonlinear behavior; Rail fastening system; Railway bridge; Serviceability evaluation method; Slab track","Finite element method; Railroad bridges; Railroad transportation; Railroads; Stiffness; Displacement-based design methods; Experimental modeling; Non-linear stiffness models; Nonlinear behavior; Numerical results; Railway bridges; Serviceability evaluation method; Slab tracks; Rails; bridge; displacement; experimental study; finite element method; nonlinearity; numerical model; railway transport",,,,,"Ministry of Land, Infrastructure and Transport, MOLIT","This research was supported by a grant (18CTAP-C129908-02) from the Infrastructure and Transportation Technology Promotion Research Program, funded by the Ministry of Land, Infrastructure and Transport of the Korean Government.",,,,,,,,,,"Kang, C., Schneider, S., Wenner, M., Marx, S., Development of design and construction of high-speed railway bridges in Germany (2018) Eng Struct, 163, pp. 184-196; Union Internationale des Chemins de fer, High speed lines in the world (2017), International Union of Railways Paris; Yan, B., Dai, G.L., Hu, N., Recent development of design and construction of short span high-speed railway bridges in China (2015) Eng Struct, 100, pp. 707-717; Gautier, P.E., Slab track: review of existing systems and optimization potentials including very high speed (2015) Constr Build Mater, 92, pp. 9-15; Giannakos, K., Deflection of a railway reinforced concrete slab track: comparing the theoretical results with experimental measurements (2016) Eng Struct, 122, pp. 296-309; Moelter, T., Closed and open joints for bridges on high speed lines (2008) Bridges for high-speed railways, pp. 191-197. , R.

A detailed inspection of the fire-exposed bridge was performed through visual checking, photo examinations, and hammer detection. Samples of the concrete cores and reinforcing bars were tested; the residual strengths of the building materials (concrete, reinforcing bars and prestressed strands) were estimated. Furthermore, the temperatures at various depths were estimated. The data from field studies were used to validate finite element models. The structural behaviors of the original bridge prior to fire exposure were obtained via instrumentation from a reference bridge not exposed to fire. The static proof load test deflection results indicate that the stiffness decreased by approximately 23% after fire exposure and no longer satisfied the design requirement. The measured fundamental frequency of the fire-exposed span was approximately 97% of that of the original span and the theoretical fundamental frequency, indicating that the fire had little influence on the frequency of the concrete structure. Based on this work, the repair requirements of the bridge were determined and undertaken, and the repairs were proven to be effective via a field loading test after strengthening. © 2019 Elsevier Ltd","Bridge fires; Field loading test; Finite element analysis; Materials testing; Prestressed concrete box girder bridge","Bars (metal); Box girder bridges; Bridge decks; Concrete beams and girders; Concrete bridges; Finite element method; Fires; Inspection; Load testing; Materials testing; Natural frequencies; Prestressed concrete; Reinforced concrete; Steel bridges; Structural design; Field loading test; Fundamental frequencies; Parametric finite elements; Prestressed concrete box girder; Residual strength; Structural behaviors; Test deflections; Visual checking; Concrete testing",,,,,"National Natural Science Foundation of China, NSFC: 51468019; China Scholarship Council, CSC: 201609795003","The authors would like to thank the Zhejiang Communications Investment Group Co., Ltd, which provided the engineering background and supported this study.

In practice, the retainers are usually designed and detailed as structural fuses to protect the substructure and foundation in high seismic zones. However, in low seismic zone, such as seismic zone 1 in AASHTO, they are designed elastic. In this paper, a parameter study was conducted to: (1)investigate the distribution of forces among the shear keys in skewed bridges and (2)evaluate AASHTO's provisions for the minimum connection force of shear keys in low seismic zone. Parameters of interest include skew angle and expansion gap size. An experimentally validated numerical model was employed to model the prototype bridges with exterior shear keys. Nonlinear response history analysis was performed. The results show that when the longitudinal gap is closed for small to moderate gaps, the forces in the keys at the acute corners can be much higher than those at the obtuse corners. This is most likely to occur since the keys should resist the transverse loading along with the impact and friction forces at the abutment-deck interface caused by longitudinal motion. These higher forces of the keys at the acute corners could exceed AASHTO's limit in low seismic zone. To reduce the forces in the keys, it is recommended that the gap be increased in size to avoid abutment pounding, which is an affordable solution in low seismic zone since the increase is expected to be small. Further, a Simplified Method is developed to estimate the maximum connection forces of skew bridges in low seismic zone. Good agreement was obtained between the Simplified Method and the FEM model. Therefore, the Simplified Method may be used for the preliminary design of shear keys. © 2019 Elsevier Ltd","Bridge abutment interaction; Dynamic analysis; Expansion gap; Girder unseating; Shear keys; Simplified method; Skew bridges","Abutments (bridge); Dynamic analysis; Friction; Longitudinal motion; Nonlinear response history analysis; Preliminary design; Seismic damage modes; Shear key; Simplified method; Skew bridges; Transverse loading; Seismology; bridge; building code; dynamic analysis; seismic design; seismic response; seismic zone; shear strength; structural analysis; structural response",,,,,"Federal Highway Administration, FHWA","Acknowledgment is made of the financial support provided by the Federal Highway Administration under Contract No. DTFH61-07-C-00031, and the expert guidance of Dr. Wen-huei (Phillip) Yen (COR), Mr. Fred Faridazar (COR) and Ms. Sheila Duwadi (COR).

It consists of the thermally conductive layer, the heating cable, the asbestos belt, and the reinforced concrete leveling course. The thermally conductive layer is proposed to replace the waterproof and cohesive layer in the traditional bridge deck. The material of the thermally conductive layer is thermally conductive cement-based composite, and it is helpful for heat transfer efficiency. Additionally, a 3D finite element heated bridge deck for snow-melting model, which was verified by field experiment, is developed to simulate the heating process of the heated bridge deck for snow-melting. According to the simulation results, the influences of insulated-conductive composite structure on the surface temperature and the damage of heated bridge deck for snow-melting were analyzed. Meanwhile, to consider both the surface temperature and damage, the structure evaluation method is proposed to recommend the optimal insulated-conductive composite structure.

However, they are not widely used in seismic regions because the understanding of confinement effect in hollow concrete columns is quite limited. To improve the understanding of confinement effect in square hollow concrete columns, this paper presents a systematic computational study using the confinement configuration, wall thickness, and confinement reinforcement amount as the primary investigated parameters. The computational results show that two layers of transverse reinforcement connected with cross-ties provide the best confinement effect for square hollow concrete columns. In addition, both wall thickness and confinement reinforcement amount are found to not significantly affect the confinement effect in square hollow concrete columns with a wall thickness ratio in the range of 0.1–0.2 and confined with a single layer of reinforcement. © 2019 Elsevier Ltd","Column; Concrete; Confinement; FE Modeling; Hollow; Seismic; Square","Bridges; Columns (structural); Concrete construction; Concretes; Plasma confinement; Reinforcement; Seismology; Computational studies; Confinement reinforcement; Effective section properties; FE model; Hollow; Seismic; Square; Transverse reinforcement; Reinforced concrete; bridge; column; concrete structure; finite element method; numerical model; seismic response",,,,,"California Department of Transportation, CT: 65A0412; National Natural Science Foundation of China, NSFC: 51808380; Natural Science Foundation of Tianjin Municipal Science and Technology Commission: 2017917AO","The authors wish to express their gratitude and sincere appreciation to the California Department of Transportation (Caltrans with the grant number of 65A0412 ), the National Natural Science Foundation of China (with grant number of 51808380 ), and the Natural Science Foundation of Tianjin Municipal Science and Technology Commission (with grant No. 2017917AO ) for financing this research work.",,,,,,,,,,"Mo, Y.L., Wong, D.C., Maekawa, K., Seismic performance of hollow bridge columns (2003) ACI Struct J, 100 (3), pp. 337-348; Kim, T.H., Seong, D.J., Shin, H.M., Seismic performance assessment of hollow reinforced concrete and prestressed concrete bridge columns (2012) Int J Concr Struct Mater, 6 (3), pp. 165-176; Lee, J.H., Choi, J.H., Hwang, D.K., Kwahk, I.J., Seismic performance of circular hollow RC bridge columns (2015) KSCE J Civ Eng, 19 (5), pp. 1456-1467; Hines, E.M., Seible, F., Priestley, M.J.N., Seismic performance of hollow rectangular reinforced concrete piers with highly-confined boundary elements Phase I: Flexural tests; Phase II: Shear tests.

It has been experimentally revealed that hot spot stress (HSS) of CFST K-joints is significantly lower than those of empty tubular K-joints in the reported researches. However, no parametric formulae on stress concentration factors (SCFs) of CFST K-joints have been established. In present study, three-dimensional FE models for determining the SCF distributions around the chord-brace intersections of CFST K-joints were developed first. The validity of the FE modelling has been examined by comparing with the published experimental results. Then 272 FE models of CFST K-joints with different geometric dimensions were prepared and provided for the parametric study to demonstrate the influence of four key geometric parameters, i.e. diameter ratio (β), diameter to thickness ratio of chord (2γ), thickness ratio (τ) and the angle (θ) between the axis of the chord and brace, on SCFs around the chord-brace intersection. The analysis was performed under three loading conditions, i.e. the basic balanced axial forces, axial compressive force in the chord and in-plane bending in the chord. Finally, parametric formulae to determine the SCFs in CFST K-joints were proposed by the multiple regression analysis, and their accuracy was demonstrated through the comparison of SCFs obtained by the proposed formulae and FEA. © 2019","CFST K-joints; Fatigue; Finite element analysis; Hot spot stress; Parametric formulae; Stress concentration factors","Arch bridges; Beams and girders; Concretes; Fatigue of materials; Finite element method; Joints (structural components); Microalloyed steel; Regression analysis; Stress concentration; Axial compressive forces; Concrete-filled steel tubular; Diameter-to-thickness ratios; Hot spot stress; K-joint; Multiple regression analysis; Parametric formulae; Stress concentration factors; Stress analysis; accuracy assessment; bridge; concrete; experimental study; fatigue; finite element method; loading; regression analysis; steel structure; stress analysis; structural component; China",,,,,"China Scholarship Council, CSC: 201506650004","This research was financially supported by China Scholarship Council (No. 201506650004 ).

In order to reduce the computational cost of the dynamic finite element analysis of the samples to gain the probability density function of structural responses, the response surface method was adopted to handle the sampling results. The stochastic pseudo excitation method combing response surface method is verified by comparing with Monte Carlo method in good agreement. As an example, the stochastic response of a super-high slender bridge tower subjected to the Davenport fluctuating wind excitations is evaluated taking into account the uncertainties of material properties and wind speed. Numerical results show that the effect of uncertainties of structure or excitations plays a constant role in the stochastic response at the different levels of external excitations. © The Author(s) 2019.","response surface method;

This study focuses on the transverse mechanical performance of bridge segments under vehicle loads; based on the fact the transverse bending stiffness of segmental box girders with CSWs is weaker than that of bridge girders with concrete webs. It is found from the experimental results that that bending failure of the top concrete flange occurs first instead of the shear buckling of the CSWs. In addition, the result of load testing indicate that the precast segmental box girder with CSWs has a high coefficient of safety margin and a good plastic deformability. This study also presents two improved schemes of structural design to enhance the structural transverse stiffness and reduce the accumulated deformation differences caused by the self-weight in the process of segmental precasting by the short-line method. © 2019 Elsevier Ltd","Corrugated steel webs; Full-scale model; Precast segment; Short-line method; Transverse analysis","Beams and girders; Concretes; Deformation; Finite element method; Safety testing; Steel testing; Stiffness; Structural design; Corrugated steel webs; Full-scale modeling; Line methods; Precast segments; Transverse analysis; Box girder bridges; bending; bridge; buckling; composite; deformation mechanism; design; finite element method; safety; steel structure; stiffness; structural analysis; testing method",,,,,"51808559; Natural Science Foundation of Shanghai","This study was supported by the National Natural Science Foundation of the People’s Republic of China (Grant 51808559 ).

For an accurate prediction of the main cable geometry of a suspension bridge, an innovative iterative method is proposed in this article. In the iteration process, hanger tensions and the cable shape are, in turns, used as inputs. The cable shape is analytically predicted with an account of the pylon saddle arc effect, while finite element method is employed to calculate hanger tensions with an account of the combined effects of the cable-hanger-stiffening girder. The cable static equilibrium state is expressed by three coupled nonlinear governing equations, which are solved by their transformation into a form corresponding to the unconstrained optimization problem. The numerical test results for the hanger tensions in an existing suspension bridge were obtained by the proposed iterative method and two conventional ones, namely, the weight distribution and continuous multiple-rigid-support beam methods. The latter two reference methods produced the respective deviations of 10% and 5% for the side hangers, respectively, which resulted in significant errors in the elevations of the suspension points. To obtain more accurate hanger tensile forces, especially for the side hangers, as well as the cable shape, the iterative method proposed in this article is recommended. © The Author(s) 2018.","cable shape; hanger tensile force; iterative method; pylon saddle; suspension bridge; tangent point; unconstrained optimization problem","Bridge cables; Finite element method; Mathematical transformations; Nonlinear equations; Numerical methods; Optimization; Suspension bridges; Cable shape; pylon saddle; Tangent point; Tensile forces; Unconstrained optimization problems; Iterative methods",,,,,"2017YFC0806009; National Natural Science Foundation of China, NSFC: 51678148; Natural Science Foundation of Jiangsu Province: BK20181277","The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: The research described in this article was financially supported by the NSFC under Grant 51678148, a project supported by the Natural Science Foundation of Jiangsu Province (BK20181277), and the National Key R&D Program of China (No. 2017YFC0806009), which are gratefully acknowledged.",,,,,,,,,,"Atmaca, B., Ates, S., Construction stage analysis of three-dimensional cable-stayed bridges (2012) Steel & Composite Structures, 12 (5), pp. 413-426; Cao, H.Y., Zhou, Y.L., Chen, Z.J., Form-finding analysis of suspension bridges using an explicit iterative approach (2017) Structural Engineering & Mechanics, 62 (1), pp. 85-95; Chen, D.W., Au, F.T.K., Tham, L.G., Determination of initial cable forces in prestressed concrete cable-stayed bridges for given design deck profiles using the force equilibrium method (2000) Computers & Structures, 74 (1), pp. 1-9; Chen, Z.J., Cao, H.Y., Zhu, H.P., An iterative calculation method for suspension bridge’s cable system based on exact catenary theory (2013) Baltic Journal of Road & Bridge Engineering, 8 (3), pp. 196-204; Hassan, M.M., Optimization of stay cables in cable-stayed bridges using finite element, genetic algorithm, and B-spline combined technique (2013) Engineering Structures, 49 (2), pp. 643-654; Huang, Y.H., Fu, J.Y., Gan, Q., New method for identifying internal forces of hangers based on form-finding theory of suspension cable (2017) Journal of Bridge Engineering, 22 (11). , (,): Article ID 04017096; Jung, M.R., Min, D.J., Kim, M.Y., Nonlinear analysis methods based on the unstrained element length for determining initial shaping of suspension bridges under dead loads (2013) Computers & Structures, 128 (5), pp. 272-285; Jung, M.R., Min, D.J., Kim, M.Y., Simplified analytical method for optimized initial shape analysis of self-anchored suspension bridges and its verification (2015) Mathematical Problems in Engineering, , 2015, : Article ID 923508; Karoumi, R., Some modeling aspects in the nonlinear finite element analysis of cable supported bridges (1999) Computers & Structures, 71 (4), pp. 397-412; Kim, H.K., Kim, M.Y., Efficient combination of a method and an initial force method for determining initial shapes of cable-supported bridges (2012) International Journal of Steel Structures, 12 (2), pp. 157-174; Kim, H.K., Lee, M.J., Chang, S.P., Non-linear shape-finding analysis of a self-anchored suspension bridge (2002) Engineering Structures, 24 (12), pp. 1547-1559; Kim, K.S., Lee, H.S., Analysis of target configurations under dead loads for cable-supported bridges (2001) Computers & Structures, 79 (29), pp. 2681-2692; Lu, P.Z., Chen, J.T., Zhong, J.R., Optimization analysis model of self-anchored suspension bridge (2014) Mathematical Problems in Engineering, 2014 (4). , (,): Article ID 403962; Thai, H.T., Choi, D.H., Advanced analysis of multi-span suspension bridges (2013) Journal of Constructional Steel Research, 90 (41), pp. 29-41; Zhang, W.M., Liu, Z., Xu, S.U., Jindong Bridge: suspension bridge with steel truss girder and prefabricated RC deck slabs in China (2018) Structural Engineering International, , (, a), Epub ahead or print 5 November; Zhang, W.M., Shi, L.Y., Li, L., Methods to correct unstrained hanger lengths and cable clamps’ installation positions in suspension bridges (2018) Engineering Structures, 171, pp. 202-213. , (, b","Zhang, W.-M.; The Key Laboratory of Concrete and Prestressed Concrete Structures of the Ministry of Education, China; email: zwm@seu.edu.cn",,,"SAGE Publications Inc.",,,,,13694332,,ASEDD,,"English","Adv.

The cantilever, which is operated in the fundamental in-plane resonance mode, is used as a microbalance with femtogram resolution. To maximize sensitivity and read-out signal amplitude of the piezo-resistive Wheatstone half bridge, the geometric parameters of the sensor design are optimized by finite element modelling (FEM). The electrical read-out of the cantilever movement is realized by piezo-resistive struts at the sides of the cantilever resonator that enable real-time tracking using a phase-locked loop (PLL) circuit. Cantilevers with minimum resonator mass of 1.72 ng and resonance frequency of ~440 kHz were fabricated, providing a theoretical sensitivity of 7.8 fg/Hz. In addition, for electrostatic NP collection, the cantilever has a negative-biased electrode located at its free end. Moreover, the counter-electrode surrounding the cantilever and a µ-channel, guiding the particle-laden air flow towards the cantilever, are integrated with the sensor chip. µ-channels and varying sampling voltages will also be used to accomplish particle separation for size-selective NP detection. To sum up, the presented airborne NP sensor is expected to demonstrate significant improvements in the field of handheld, micro-/nanoelectromechanical systems (M/NEMS)-based NP monitoring devices. © 2019 by the authors.

This ensures the adhesion of the oxidized protective layer as for aluminium. Therefore, the stable rust layer protects the raw material from further corrosion. This characteristic overcomes the need for painting and maintenance. These properties boost the exploitation of Cor-Ten in several civil applications, also where safety is a fundamental requirement, e.g. guard rails used, for example, in the South-Tyrolean region along the highways. With the aim of verifying or optimizing such safety applications, it is important to know the ductile behavior of the material. Indeed, during an impact, the main purpose of the structure is to absorb energy and this implies that large deformations will take place. Experimental quasi-static tests were performed on several sample geometries made of Cor-Ten. The same tests were also numerically reproduced, to retrieve the actual stress state, quantify the plastic strain at failure and calibrate a ductile damage model. The material model is based on both the classical incremental model of plastic response with isotropic hardening and the phenomenological concept of damage in continuum mechanics. © 2019 WIT Press.","Cor-Ten; Ductile fracture; Experimental; FEM; Fracture locus",,,,,,,,,,,,,,,,,"Decker, P., Brüggerhoff, S., Eggert, G., To coat or not to coat?

To investigate the mechanism of fatigue crack propagation and the influence of the welding residual stress on the propagation patterns of fatigue cracks, a multiscale modeling method was proposed, and the static analysis and the dynamic propagation analysis of fatigue crack were carried out in this paper. First, a multiscale finite element model was established, including whole bridge models with a scale feature of 102 m, orthotropic bridge deck models with a scale feature of 100 m, and crack models with a scale feature of 10-3 m. Then, a segmental model of the bridge deck was extracted, which is regarded as a critical location of the bridge, and the shell-solid coupling method is adopted in the segmental model in order to further analyze the crack propagation rule. Moreover, based on the extended finite element method (XFEM), the static crack and dynamic crack propagation in this critical position were analyzed. Finally, thermoelastoplastic analysis was carried out on the connection of the U-rib and deck with a length of 500 mm to obtain the residual stress, and then the results of residual stress were introduced into the segmental model to further study its influence on the evolution of fatigue crack propagation. The analysis of the welding process shows that near the weld region of the connection of the U-rib and deck, the peak value of the residual tensile stress can reach the material yield strength. The static analysis of fatigue cracks shows that under the single action of a standard fatigue vehicle load, the fatigue details at the weld toe of the deck cannot reach the tensile stress required for fatigue crack propagation, and only the fatigue details at the weld toe of the U-rib can meet the requirements of fatigue crack propagation. The dynamic analysis of fatigue cracks reveals that the crack in the weld toe of the U-rib is a mixed-mode crack with modes I, II, and III. The propagation of a fatigue crack without a residual stress field will be terminated until the crack length is extended to a certain length. Nevertheless, when the residual stress field was introduced, the growth angle and size of the fatigue crack would increase, and no crack closure occurs. For the crack in the weld toe of the deck, the crack is in the closed state under the standard fatigue vehicle load. When the residual stress field is introduced, the tensile stress of the fatigue details increases. Meanwhile, the fatigue crack will become a mixed-mode crack with modes I, II, and III that will be dominated by mode I and extend toward the weld at a slight deflection angle. The results of various initial crack sizes at the weld toes of the top deck are analyzed, which shows that the initial crack size has a certain effect on the fatigue crack growth rate, especially the initial crack depth. © 2019 Ying Wang et al.",,,,,,,"National Natural Science Foundation of China, NSFC: 51678135; Natural Science Foundation of Jiangsu Province: BK20171350; Six Talent Peaks Project in Jiangsu Province: JNHB-007; Fundamental Research Funds for the Central Universities: 2242016R30009; Priority Academic Program Development of Jiangsu Higher Education Institutions, PAPD","+e works described in this paper are substantially supported by the grant from the National Natural Science Foundation of China (grant no. 51678135); the Natural Science Foundation of Jiangsu Province (no.

A novel hybrid retrofitting procedure, including the application of inner steel profiles and outer peripheral CFRP sheets, has been proposed for strengthening purpose. Seven large-scale RC columns of a Girder Bridge have been tested in the laboratory under the influence of simultaneous application of constant axial load and the lateral cyclic displacements. Having verified the finite element modeling, using ABAQUS software, the effects of important parameters such as the corrosion percentage of steel rebars and the number of CFRP layers have been evaluated. Based on the results, retrofitting of RC columns of the bridge with the proposed technique was effective in improving some measures of structural performance such as lateral strength degradation and higher energy absorption capability. However, the displacement ductility was not considerably improved whereas the elastic stiffness of the specimens has been increased.

Research finds that fatigue cracks at cutout detail are highly related to wheel path. Biaxial compression at cutout detail implies high residual stress and it suffers severe out-of-plane distortion. Fatigue life can be evaluated based on category B with stress location 5 mm away from free edge of cutout. It is concluded that serious overweight trucks, significant stress concentration, too thin diaphragms, and poor finish condition jointly contribute to early cracking at cutout detail. © 2020 Elsevier Ltd","Cutout detail; Fatigue crack; FEM; Field measurement; Orthotropic bridge deck (OBD)","Fatigue damage; Finite element method; Biaxial compression; Damage investigation; Diaphragm cutouts; Field measurement; Orthotropic bridge decks; Out-of-plane distortions; Stress behavior; Stress location; Cracks",,,,,"201903; NTF18014; National Natural Science Foundation of China, NSFC: 51878269","This work was supported by the National Natural Science Foundation of China [grant number 51878269 ]; the STU Scientific Research Foundation for Talents of China [grant number NTF18014 ]; and the Open Foundation of Key Laboratory of Structure and Wind Tunnel of Guangdong Higher Education Institutes of China [grant number 201903 ], to which the writers gratefully appreciate.",,,,,,,,,,"US Department of Transportation Manual for Design, Construction, and Maintenance of Orthotropic Steel Deck Bridges (2012), February; Lwin, M., The FHWA manual for design, construction, and maintenance of orthotropic steel deck bridges (2015) ASCE/The 4th Orthotropic Bridge Conference Proceedings, September 21–24, pp. 125-136. , Tianjin, China; Wolchuk, R., Lessons from weld cracks in orthotropic decks on three European bridges (1992) J.

In the proposed concept, a modular multi-level converter (MMC) is used to step-down the three-phase medium voltage of 10 kV, and provide up to 1 MW of pure DC power to the load consisting of electrolyzers for hydrogen generation. Therefore, each module is extended by an LLC resonant converter to adapt to the specific electrolyzers DC voltage range of 142...220 V and to provide galvanic isolation. In order to achieve a high efficiencyfor a wide range of load conditions, the input voltage of the LLC converter is adjusted between 600V and 770 V while operating at resonance or close to resonance. The parameters of the 11 kW LLC resonant converter with an integrated leakage inductance are systematically optimized to maximize the efficiency for all loads while achieving zero-voltage switching. For a fast estimation of eddy current losses, a new method is proposed, which uses a single FEM simulation to fit newly developed loss equations. The calculated average efficiency is 97.8 %. The prototype of the LLC converter reaches a peak efficiency of over 98 % at resonance at half load which is similar to the precalculated value. © 2020 IEEE.","Full-bridge; High voltage power converters; LLC resonant converter; Multilevel converters; ZVS Converters","Design; Efficiency; Electrolysis; Electrolytic cells; HVDC power transmission; Hydrogen production; Resonance; Zero voltage switching; At resonance; Electrolyzers; Full bridge; High voltage power converters; Input voltages; LLC converter; LLC resonant converter; Modular multilevel converters (MMC); Multilevel converter; ZVS converters; Power converters",,,,,"Deutsche Forschungsgemeinschaft, DFG: 314461654","German Research Foundation (DFG) funded this research on modular-multilevel converters under the project number 314461654.",,,,,,,,,,"Pratt, A., Kumar, P., Aldridge, T.V., Evaluation of 400v dc distribution in telco and data centers to improve energy efficiency (2007) INTELEC 07-29th International Tel.

In this theoretical method, formulas for the equivalent area of stiffening bar and the shear flow in corrugated steel webs (CSWs) are derived by properly considering the mechanical properties of non-prismatic CBGCSWs. The governing differential equations for shear lag are formulated and solved with given boundary conditions. The feasibility of the proposed method is validated by the finite element (FE) method based on a non-prismatic cantilever beam under different loading conditions. In addition, the shear lag behavior of non-prismatic cantilever CBGCSWs is compared with that of corresponding concrete box girders, and the effects of width-span ratio, girder height ratio, changing curve of girder height and loading form on the shear lag effect of non-prismatic cantilever CBGCSWs are examined based on the modified bar simulation method. Results indicate that non-prismatic cantilever CBGCSWs exhibit more significant shear lag behavior than the corresponding concrete box girders under gravity. The distribution rule of shear flow in concrete flanges, which first increase and then decrease from the cantilever end to the fixed end, causes the transformation between negative and positive shear lag effects in non-prismatic cantilever beams. Increasing the width-span ratio or girder height ratio leads to more serious shear lag effect. The effect of loading form on the shear lag behavior is significant, while the changing curve of girder height has minimal influence. © 2020 Elsevier Ltd","Bar simulation method; Composite box girders with corrugated steel webs; Finite element analysis; Non-prismatic; Parametric study; Shear lag effect","Boundary conditions; Box girder bridges; Cantilever beams; Concrete beams and girders; Fiber optic sensors; Nanocantilevers; Shear flow; Composite box girder; Concrete box girders; Corrugated steel webs; Distribution rule; Governing differential equations; Non-prismatic cantilever; Shear lag analysis; Theoretical methods; Loading",,,,,"HMDDGC-D-03; National Natural Science Foundation of China, NSFC: 51978257; Natural Science Foundation of Hunan Province: 2020JJ4310; Natural Science Foundation of Shaanxi Provincial Department of Education: 18A202, 18C0311","This research is sponsored by the National Natural Science Foundation of China (Grant 51978257), the Science and Technology Program of Transportation Bureau of Huadu District, Guangzhou, China (Grant HMDDGC-D-03), the Natural Science Foundation of Hunan Province (Grant 2020JJ4310) and the Natural Science Foundation of Hunan Provincial Department of Education (Grants 18A202 and 18C0311).

The novel pre-pressure regulating mechanism is used to adjust pre-pressure along the axial direction of the stators simultaneously and homogeneously, so as to ensure the stability of the motor output. Using finite element method, the admittance circle is obtained by frequency domain analysis, which can estimate the resonance frequency and electrical parameters of the motor, and the coordinated driving trajectories of the three stators at different tilt angles are predicted by transient analysis. After the fabrication of a prototype, the admittance characteristics of piezoelectric stator are tested by LCR digital bridge measurement unit. Meanwhile, the mechanical output speed is measured. The rotational speeds of X-axis, Y-axis and Z-axis can reach 29 r/min, 17 r/min and 16 r/min respectively when the frequency matches, which verifies the feasibility and rationality of the multi-DOF movement of the motor. © 2020 Elsevier B.V.","Admittance circle; Mechanical output speed; Motion trajectory; Multi-DOF; Spherical ultrasonic motor","Degrees of freedom (mechanics); Piezoelectric devices; Piezoelectric motors; Piezoelectricity; Stators; Transient analysis; Ultrasonic devices; Ultrasonic machine tools; Electrical parameter; Frequency match; Multi degree-of-freedom; Piezoelectric-driven; Resonance frequencies; Rotational speed; Spherical ultrasonic motor; Ultrasonic motors; Frequency domain analysis",,,,,"ZD2018228; National Natural Science Foundation of China, NSFC: 51577048, 51877070; Anhui University: KFKT201901; Natural Science Foundation of Hebei Province: A201905008, E2018208155","This work is supported by the National Natural Science Foundation of China , grant No. 51877070 , 51577048 , the Natural Science Foundation of Hebei Province of China , grant No. E2018208155 , the Talent Engineering Training Support Project of Hebei Province , grant No. A201905008 , the National Engineering Laboratory of Energy-saving Motor & Control Technique, Anhui University , grant No. KFKT201901 , Hebei Province Higher Education Science and Technology Research Key Project , grant No. ZD2018228 .",,,,,,,,,,"Sashida, T., Kenjo, T., An Introduction to Ultrasonic Motors (1993), Clarendon Press Oxford, UK; Nakamura, K., Ultrasonic Transducers: Materials and Design for Sensors, Actuators and Medical Applications (2012), Woodhead Publishing Cambridge, UK; Zhao, C., Ultrasonic Motors: Technologies and Applications (2011), Science Press Beijing, China; Huang, Z., Shi, S., Chen, W., Wang, L., Wu, L., Liu, Y., Development of a novel spherical stator multi-DOF ultrasonic motor using in-plane non-axisymmetric mode (2020) Mech.

However, the segmental joints cause structural discontinuities, which generate more complicated mechanical behaviors than those observed with monolithic girders. Specifically, for PCSGs with external tendons, increasing attention is being paid to their structural analysis and design. In this paper, a new highly efficient numerical model is proposed for flexural behavior analysis of PCSGs over all the elastoplastic loading states. The proposed model is a beam-tendon element hybrid model comprising three components: the concrete box girder segment element, multi-node slipping tendon element and joint element. All of the elements are built considering the crucial mechanical behavior of PCSGs. A 10 degree-of-freedom (DOF) fiber beam element is proposed as the segment element to consider the shear lag effects, geometric and materially nonlinear behavior of the concrete box girder. A multi-node co-rotational slipping tendon element is proposed to model the slip effect and stiffness contribution of the un-bonded or external tendons. The discontinuous mechanical behavior between the segments is simulated using plain concrete joint elements with a modified constitutive relation based on the equivalent of the cracking and crushing energy. The finite element (FE) formulas and the modified method are deduced and presented in the paper and then implemented in OpenSees software as newly developed elements. Utilizing the developed procedure, the proposed model is thoroughly validated through comparisons with several scaled and full-scale experimental results, including structural deformations, ultimate capacity, traction increments of tendons and the width of the open joints. The results reveal the superior applicability and computational efficiency of the proposed model compared with previous models. Finally, the model is applied to a practice bridge for structural performance analysis under service and ultimate states. The applicability of the current design formulas is discussed based on the analytical results of the proposed model. © 2020 Elsevier Ltd","Flexural behavior; Joint; Numerical model; Precast concrete segmental box girders; Prestressed tendons","Box girder bridges; Computational efficiency; Degrees of freedom (mechanics); Numerical models; Precast concrete; Shear flow; Structural analysis; Tendons; Constitutive relations; Construction technologies; Degree of freedom (dof); Elasto-plastic loading; Structural analysis and designs; Structural deformation; Structural discontinuity; Structural performance analysis; Concrete beams and girders; concrete structure; elastoplasticity; experimental study; finite element method; flexure; numerical model; slip; software; stiffness; structural component",,,,,"2017-SF-139; National Natural Science Foundation of China, NSFC: 51608031, 51678030, 51708020; Hebei Province Science and Technology Support Program: QG2018-8","The authors would like to acknowledge the following financial supports to carry out the research: National Natural Science Foundation of China under Grant Nos. 51678030, 51608031 and 51708020 , the Science and Technology Foundation of Tsinghai Province (Grant No. 2017-SF-139 ), and the Transportation Science and Technology Program of Hebei Province (Grant No. QG2018-8 ).","The authors would like to acknowledge the following financial supports to carry out the research: National Natural Science Foundation of China under Grant Nos. 51678030, 51608031 and 51708020, the Science and Technology Foundation of Tsinghai Province (Grant No. 2017-SF-139), and the Transportation Science and Technology Program of Hebei Province (Grant No. QG2018-8).",,,,,,,,,"Yuan, A., He, Y., Dai, H., Cheng, L., Experimental study of precast segmental bridge box girders with external unbonded and internal bonded posttensioning under monotonic vertical loading (2015) J Bridge Eng, 20, p. 04014075; Jiang, H., Cao, Q., Liu, A., Wang, T., Qiu, Y., Flexural behavior of precast concrete segmental beams with hybrid tendons and dry joints (2016) Constr Build Mater, 110, pp. 1-7; Chai, S., Guo, T., Chen, Z., Yang, J., Monitoring and simulation of long-term performance of precast concrete segmental box girders with dry joints (2019) J Bridge Eng, 24, p. 04019043; Liu, T., Wang, Z., Guo, J., Wang, J., Shear strength of dry joints in precast UHPC segmental bridges: experimental and theoretical research (2019) J Bridge Eng, 24, p. 04018100; Yuan, A., Yang, C., Wang, J., Chen, L., Lu, R., Shear behavior of epoxy resin joints in precast concrete segmental bridges (2019) J Bridge Eng, 24, p. 04019009; Zhou, X., Mickleborough, N., Li, Z., Shear strength of joints in precast concrete segmental bridges (2005) ACI Struct J, 105, pp. 3-11; Jiang, H., Chen, L., Ma, Z.J., Feng, W., Shear behavior of dry joints with castellated keys in precast concrete segmental bridges (2015) J Bridge Eng, 20, p. 04014062; Iglesias, C., Long-term behavior of precast segmental cantilever bridges (2006) J Bridge Eng, 11, pp. 340-349; Malm, R., Sundquist, H., Time-dependent analyses of segmentally constructed balanced cantilever bridges (2010) Eng Struct, 32, pp. 1038-1045; Hindi, A., Macgregor, R., Kreger, M.E., Breen, J.E., Enhancing strength and ductility of post-tensioned segmental box girder bridges (1995) ACI Struct J, 92, pp. 33-44; Aparicio, A.C., Ramos, G., Casas, J.R., Testing of externally prestressed concrete beams (2002) Eng Struct, 24, pp. 73-84; Kim, J., Chung, W., Jay Kim, J.-H., Experimental investigation on behavior of a spliced PSC girder with precast box segments (2008) Eng Struct, 30, pp. 3295-3304; Saibabu, S., Srinivas, V., Sasmal, S., Lakshmanan, N., Iyer, N.R., Performance evaluation of dry and epoxy jointed segmental prestressed box girders under monotonic and cyclic loading (2013) Constr Build Mater, 38, pp. 931-940; Yuan, A., Dai, H., Sun, D., Cai, J., Behaviors of segmental concrete box beams with internal tendons and external tendons under bending (2013) Eng Struct, 48, pp. 623-634; Le, T.D., Pham, T.M., Hao, H., Haoc, Y., Flexural behaviour of precast segmental concrete beams internally prestressed with unbonded CFRP tendons under four-point loading (2018) Eng Struct, 168, pp. 371-383; Le, T.D., Pham, T.M., Hao, H., Yuan, C., Performance of precast segmental concrete beams posttensioned with carbon fiber-reinforced polymer (CFRP) tendons (2019) Compos Struct, 208, pp. 56-69; Takebayashi, T., Deeprasertwong, K., Leung, Y.W., A full-scale destructive test of a precast segmental box girder bridge with dry joints and external tendons (1994) Proc Inst Civil Eng Struct Build, 104, pp. 297-315; (1999), AASHTO.

However, because of the limitations of the parameters considered in previous tests and the difficulty of measuring the internal stress states of test specimens, the force transfer mechanisms of perfobond connectors in steel-concrete joints remain unclear. To clarify shear behavior of perfobond connectors in the steel-concrete joints of hybrid bridges, an effective finite element model of push-out testing is developed. Finite element analysis results indicated that: the dilatancy effect of concrete dowel causes concrete cracking, and the shear capacity of connectors is mainly controlled by the confinements of structural reinforcement in the y direction. In the case of weak confinements from structural reinforcement, the confinement effects of friction force at the bottom of a specimen significantly affects the mechanical properties of concrete dowels. Pressure fields can slightly enhance the shear capacity of connectors, whereas tension fields can significantly reduce the ultimate shear capacity of connectors. With an increase in confinements, the shear and tension forces of the perforating rebar in the ultimate state gradually shift toward pure shear forces. Because of the separation of steel-concrete interfaces caused by the dilatancy of concrete dowels, the contribution of interface bond friction to the shear capacity of connectors should be considered as a safety reserve. © 2020 Elsevier Ltd","Dilatancy; Finite element analysis; Perfobond connector; Shear behavior; Steel-concrete joints","Concrete beams and girders; Concrete testing; Fasteners; Finite element method; Friction; Reinforcement; Steel testing; Surface tension; Confinement effects; Force transfer mechanism; Properties of concretes; Steel concrete composite beam; Steel-concrete interface; Steel-concrete joints; Structural reinforcement; Ultimate shear capacities; Shear flow",,,,,"Chongqing Postdoctoral Science Foundation: cstc2019jcyj-bshX0067; National Natural Science Foundation of China, NSFC: 51608069","The authors express their sincere gratitude for the financial support provided by the Chongqing Postdoctoral Science Foundation ( cstc2019jcyj-bshX0067 ) and National Natural Science Foundation of China ( 51608069 ).",,,,,,,,,,"Oguejiofor, E.C., Hosain, M.U., Behaviour of perfobond rib shear connectors in composite beams: full-s...[J] (1992) Can.

Since then, tyre-derived products have been widely used in road applications. One of these applications is in tyre bales, comprising 100–140 car vehicle tyres compressed into a lightweight block and secured by galvanised steel tie wires running around the length and depth of the bale. In the scope of the project reported here, the authors conducted comprehensive laboratory and field tests on applying tyre bales and shreds as a backfill to integral bridges. In this paper, a full-scale experiment is described in which the pressure of a tyre-baled backfill supplemented with medium sand filling and a tyre shreds buffer layer has been evaluated. The experiment was prepared and conducted by means of a special full-scale trial built to simulate real bridge abutment conditions. Test results clearly revealed the efficiency of the backfill composed of tyre bales, tyre shreds and medium sand filling in terms of pressure reduction on a bridge abutment in comparison with pressure distribution of homogeneous soil pressure. A finite element 2D analysis was also conducted to model the behaviour of a waste tyre/sand backfill. Since there was pretty good agreement between numerical and experimental results, the validated FE analysis might be reliably adopted in further design for a sustainable bridge solution. The first Polish application of the abutment backfill from waste tyres has been briefly described as well. © 2020 The Authors","FE analysis; Full-scale experiment; Tyre bales; Tyre shreds bridge abutment; Waste tyres","backfill; bridge; computer simulation; design; experimental study; finite element method; numerical model; pressure field; recycling; sand; soil-structure interaction; tire; two-dimensional modeling; waste disposal; Poland [Central Europe]",,,,,"European Regional Development Fund, FEDER","This research has been carried out in the frame of the R&D project called “ ReUse—Innovative Recycling Materials, Enhancing the Sustainability of Bridge Facilities ” (Innotech No. K3/IN3/38/228116/NCBiR/15 ), co-financed by the European Regional Development Fund and the research & industry consortium of Promost Consulting Rzeszow (leader of consortium), Remost Debica, Geotech Rzeszow and Rzeszow University of Technology.",,,,,,,,,,"European Union.

ABAQUS FEA software has been adopted. Composite steel beams encased in fiber reinforced concrete are analyzed and a comparison is made with available experimental results. Good agreement with the experimental results is observed. Upwards camber of the steel section is introduced on the steel joist. It's found that the preflex section can increase the ultimate load capacity by 10% and decrease midspan displacement by 13% of the same beams without the preflex steel section. Steel fiber dosages, compressive strength, modulus of rupture are examined. The effect of cambering and mesh refinement is also investigated. The physical properties of SFRC are calculated through testing at the UTA Civil Engineering Laboratory Building. In total, nine (4″ x 8″) cylindrical specimens, nine (6″ x 12″) cylindrical specimens, and nine (6″ x 6″ x 20″) beam specimens were produced and tested for their compressive strength, tensile strength, and modulus of rupture after 28 days of curing. The addition of steel fiber will lead to a significant increase in tensile strength and modulus of rupture of concrete. Adding 1% steel fibers by volume can increase the load capacity by 33% and decrease the midspan displacement by 70% in comparison to the same beam using plain concrete. The increase in steel fibers and cambering shows an improvement to the flexural capacity and cracking point of the beam, which can provide mo re strength to structures such as long-span bridges. © 2020","Camber; Flexural capacity; Load capacity; Preflex; SFRC","ABAQUS; Bars (metal); Behavioral research; Composite beams and girders; Compressive strength; Concrete beams and girders; Concrete construction; Fiber reinforced concrete; Laboratories; Nonlinear analysis; Steel structures; Tensile strength; Cylindrical specimens; Engineering laboratories; Flexural behavior; Flexural capacity; Long-span bridge; Mid-span displacements; Modulus of rupture; Ultimate load capacity; Steel fibers",,,,,,,,,,,,,,,,"Lok, T.-S., Pei, J.-S., Flexural behavior of steel fiber reinforced concrete (1998) J.

In the present study, wind-induced response of an inclined smooth cable was studied through wind tunnel measurements using a flexible cable model for a better understanding of the vibration characteristics of structural cables in atmospheric boundary layer wind. For this purpose, in-plane and out-of-plane responses of a sagged and a non-sagged flexible cable were recorded by four accelerometers. Four cases with different yaw and inclination angles of a cable with approximate sag ratios of 1/10 were studied to investigate the wind directionality effect on its excitation mode(s) and response amplitude. Cable tension was also measured during all experiments to assess the correlation of wind speed, excitation vibration mode, and natural frequency of the cable with change in cable tension. Additionally, two inclined cables with no sag were tested to determine the influence of sag of a cable on its vibration characteristics. In the second part of this study, a series of finite element analyses were conducted to predict the wind-induced aerodynamic damping of an inclined bridge cable. Experimental results showed that excitation mode(s) of a cable depend on wind speed, inclination angle, and sag ratio and cable tension. First, second, and third vibration modes were observed at a low wind speed for different test cases, whereas higher vibration modes were observed to contribute to the cable response at high wind speeds. Moreover, it was seen that the cable tension significantly increased with wind speed resulting in increased value of the excited natural frequency. Numerical results obtained through finite element analysis of an inclined full-scale cable showed that the criteria that are based on section models can underestimate the critical reduced velocity for dry cable galloping. © 2020 Elsevier Ltd","Aerodynamic cable damping; Aeroelastic cable model; Dry galloping; FEA of cable; Inclined cable; Wind-induced vibration","Atmospheric boundary layer; Bridge cables; Failure (mechanical); Finite element method; Natural frequencies; Speed; Vibration analysis; Wind; Wind tunnels; Catastrophic failures; Correlation of wind speed; Flexible cable model; Large amplitude vibrations; Out-of-plane response; Vibration characteristics; Wind tunnel measurements; Wind-induced response; Cable stayed bridges; boundary layer; cable; damping; dynamic analysis; dynamic response; experimental study; finite element method; loading; numerical model; vibration; wind direction; wind stress; wind velocity",,,,,"National Science Foundation, NSF: 1537917, CMMI-1537917","The authors gratefully acknowledge the U.S. National Science Foundation (NSF) for financially supporting this research under grant # CMMI-1537917 .",,,,,,,,,,"Martins, F.A.C., Avila, J.P.J., Effects of the Reynolds number and structural damping on vortex-induced vibrations of elastically-mounted rigid cylinder (2019) Int J Mech Sci, 156, pp. 235-249; Xu, W., Ma, Y., Cheng, A., Yuan, H., Experimental investigation on multi-mode flow-induced vibrations of two long flexible cylinders in a tandem arrangement (2018) Int J Mech Sci, 135, pp. 261-278; Liu, M., Yang, W., Chen, W., Xiao, H., Li, H., Experimental investigation on vortex-induced vibration mitigation of stay cables in long-span bridges equipped with damped crossties (2019) J Aerosp Eng, 32, pp. 1-10; Li, H., Chen, W.L., Xu, F., Li, F.C., Ou, J.P., A numerical and experimental hybrid approach for the investigation of aerodynamic forces on stay cables suffering from rain-wind induced vibration (2010) J Fluids Struct, 26, pp. 1195-1215; Wang, J., Lu, P., Bi, J.H., Guan, J., Qiao, H.Y., Three-phase coupled modelling research on rain-wind induced vibration of stay cable based on lubrication theory (2016) J Fluids Struct, 63, pp. 16-39; Ge, Y., Chang, Y., Xu, L., Zhao, L., Experimental investigation on spatial attitudes, dynamic characteristics and environmental conditions of rain–wind-induced vibration of stay cables with high-precision raining simulator (2018) J Fluids Struct, 76, pp. 60-83; Jing, H., Xia, Y., Li, H., Xu, Y., Li, Y., Excitation mechanism of rain–wind induced cable vibration in a wind tunnel (2017) J Fluids Struct, 68, pp. 32-47; He, X., Cai, C., Wang, Z., Jing, H., Qin, C., Experimental verification of the effectiveness of elastic cross-ties in suppressing wake-induced vibrations of staggered stay cables (2018) Eng Struct, 167, pp. 151-165; Zhang, D., He, Z., Huang, Z., Jiang, W., Isogeometric collocation method for the galloping of an iced conductor (2017) J Eng Mech, 143, p. 04017009; Demartino, C., Ricciardelli, F., Assessment of the structural damping required to prevent galloping of dry HDPE stay cables using the quasi-steady approach (2018) J Bridg Eng, 23, pp. 1-17; Tokoro, S., Komatsu, H., Nakasu, M., Mizuguchi, K., Kasuga, A., Study on wake-galloping employing full aeroelastic twin cable model (2000) J Wind Eng Ind Aerodyn, 88, pp. 247-261; Matsumoto, M., Yagi, T., Hatsuda, H., Shima, T., Tanaka, M., Naito, H., Dry galloping characteristics and its mechanism of inclined/yawed cables (2010) J Wind Eng Ind Aerodyn, 98, pp. 317-327; Jafari, M., Sarkar, P.P., Parameter identification of wind-induced buffeting loads and onset criteria for dry-cable galloping of yawed/inclined cables (2019) Eng Struct, 180, pp. 685-699; Cheng, S., Irwin, P.A., Tanaka, H., Experimental study on the wind-induced vibration of a dry inclined cable-Part II: Proposed mechanisms (2008) J Wind Eng Ind Aerodyn, 96, pp. 2254-2272; Cheng, S., Larose, G.L., Savage, M.G., Tanaka, H., Irwin, P.A., Experimental study on the wind-induced vibration of a dry inclined cable-Part I: Phenomena (2008) J Wind Eng Ind Aerodyn, 96, pp. 2231-2253; Benidir, A., Flamand, O., Dimitriadis, G., The impact of circularity defects on bridge stay cable dry galloping stability (2018) J Wind Eng Ind Aerodyn, 181, pp. 14-26; Duy, H.V., Katsuchi, H., Yamada, H.N.M., Experimental study on dry-state galloping with various wind relative angles and its countermeasures (2014) J Struct Eng, 60A, pp. 428-436; Yeo, D.J.N., A mechanism for large amplitude, wind-induced vibrations of stay cables (2009) Proc. 11th Am.

Cracks could gradually initiate and propagate at structural details that might trigger failures of the structural members or the entire structural system. To predict the remaining fatigue life of slender coastal bridges, stochastic fatigue damage for structural details is quantified using machine learning (ML)-based methods, such as support vector machines (SVM), Gaussian process (GP), neural network (NN), and random forest (RF). Parametric probabilistic models for vehicles, defined based on long-term field measurements, and stochastic loadings from wind and waves, parameterized for various loading scenarios, serve as the input parameters. As for the output of ML models, equivalent fatigue damage accumulation is obtained based on the coupled vehicle-bridge-wind-wave (VBWW) system and stress analysis for complex structural details using multiscale finite-element analysis (FEA). With different training strategies, fatigue life for critical local details is obtained considering the ever-changing coastal environmental conditions. Training and testing results show that the GP algorithm outperforms other algorithms even though all algorithms exhibit the reasonable capability of predicting the fatigue damage accumulation. © 2020 American Society of Civil Engineers.","Gaussian process algorithm; Machine learning; Probabilistic fatigue damage assessment","Complex networks; Computer aided engineering; Decision trees; Fatigue damage; Learning systems; Stochastic models; Stochastic systems; Stress analysis; Support vector machines; Vehicles; Environmental conditions; Equivalent fatigue damage; Fatigue damage accumulation; Multiscale finite element; Parametric probabilistic model; Remaining fatigue life; Stochastic fatigue damages; Training and testing; Failure (mechanical)",,,,,"National Science Foundation, NSF","This material was based upon the work supported by the National Science Foundation under Grant No. CMMI-1537121.

In this study, an efficient probabilistic assessment framework for cross-sea bridges was developed by combining a wind-wave bridge (WWB) model with machine learning methods. The WWB model was first proposed based on finite element analysis (FEA) where the wind and wave parameters were obtained by structural health monitoring (SHM) and then correlated using copula models. The coupling effects in the wind-bridge and the wave-bridge were solved using the Newmark-β method. Taking a cable-stayed bridge as an example to illustrate the accuracy and efficiency of the proposed method, the WWB model was established and then performed to compute the dynamic response at different positions on the bridge. To deal with the time-consuming issues, a learning machine including support vector regression (SVR) and Latin hypercube sampling (LHS) was implemented to substitute further finite element calculations. The WWB model was simplified parametrically as response surfaces for stochastic wind and wave variables, and probabilistic simulations with a large number of samples were performed. The results show that the wind load controlled the displacement response of the girder, while the wave load dominated the base shear response of the foundation. The bridge response, considering when wind and waves were correlated, was 6%-25% lower than that when wind and waves were independent. Further response contour analysis demonstrated a direct relationship between the environmental parameters and the structural response to quickly estimate the bridge's maximum response in different return periods. © 2020 American Society of Civil Engineers.","Copula model; Cross-sea bridge; Machine learning; Stochastic response; Wind-wave bridge model","Cable stayed bridges; Machine learning; Stochastic models; Stochastic systems; Structural health monitoring; Support vector regression; Displacement response; Environmental parameter; Latin hypercube sampling; Machine learning methods; Probabilistic assessments; Probabilistic simulation; Structural health monitoring (SHM); Support vector regression (SVR); Shear flow",,,,,"National Natural Science Foundation of China, NSFC: 51525804","This work was supported financially by the National Natural Science Foundation of China (Grants No. 51525804).",,,,,,,,,,"An, Y., Pandey, M.D., The r largest order statistics model for extreme wind speed estimation (2007) J.

In this paper, a combination vibration reduction (CVR) strategy of hollow-closed-wall in-filled trench (HIT) and elastic bearing (EB) is proposed to decrease environmental vibration induced by HSR train, in which the depth of HIT could be well controlled to benefit the practical construction and economic cost. Based on the multi-body dynamics and finite element theory, HSR environmental vibration system is established and then divided into two sub-models including the ‘train-track-bridge’ vibration source sub-model and the ‘pile-soil’ vibration propagation sub-model. The two sub-models are connected via the force balance condition of the pier bottom. The verification of numerical models is conducted by comparing with the empirical formula and the ground data in the references. Then the attenuation law of environmental vibration is analyzed, and the vertical component is shown to be dominant in the HSR environmental vibration. On this basis, numerical simulations are performed to analyze the environmental vibration reduction under three strategies, namely the HIT, EB, and CVR. The results show that the HIT presents a distinct vibration reduction effect in the frequency range above 4 Hz and the vibration reduction becomes more obvious as the HIT's depth increases. However, the depth should be larger than 8 m to satisfy the code requirement; the EB presents an obvious reduction in the frequency range above 8 Hz; the CVR strategy not only further decrease the environmental vibration, but also effectively reduce the HIT's depth. By numerical analysis, the combination strategy of 6 m deep HIT and 2200 kN/mm vertical stiffness EB is recommended in the HSR environmental vibration reduction, which could also satisfy the limit of Chinese railway code. © 2020 Elsevier Ltd","Combination vibration reduction strategy;

However, the glued shafts showed numerous risks due to the instability of chemical glues. To avoid potential risks, filament winding with integrated flanges was proposed to prepare carbon fiber-reinforced composite (CFRP) drive shafts in this study. The natural frequency and damping of CFRP shafts were investigated by FEA and experiment. Results revealed that the natural frequency of CFRP shafts embedded in metal flanges is slightly lower than that of the glued CFRP shafts. The metal flanges did not affect the changing trend of the natural frequency with various fiber ply angles or thicknesses, and the damping had little effect on the natural frequency. The natural frequency of CFRP tubes and drive shafts was predicted using FEA and agreed well with the experimental results. The results of this study will be of great significance in the design and application of CFRP drive shafts. © 2019","CFRP drive shaft; Damping; Filament winding; Metal flange; Natural frequency","Bridge decks; Damping; Electric windings; Fiber reinforced plastics; Flanges; Glues; Gluing; Metals; Natural frequencies; Reinforcement; Carbon fiber reinforced composite; CFRP tubes; Changing trends; Design and application; Ply angles; Potential risks; Vibration characteristics; Winding technology; Filament winding",,,,,"Science and Technology Commission of Shanghai Municipality, STCSM: 16DZ112140, 18DZ1101003; Fundamental Research Funds for the Central Universities: 2232018A3-02","This work was supported by Fundamental Research Funds for the Central Universities (No. 2232018A3-02 ), Science and Technology Committee of Shanghai Municipality (No. 18DZ1101003, No.16DZ112140).",,,,,,,,,,"Kim, H.S., Park, S.W., Hwang, H.Y., Lee, D.G., Effect of the smart cure cycle on the performance of the co-cured aluminum/composite hybrid shaft (2006) Compos Struct, 75, pp. 276-288; Shokrieh, M.M., Hasani, A., Lessard, L.B., Shear buckling of a composite drive shaft under torsion (2004) Compos Struct, 64, pp. 63-69; Eksi, S., Kapti, A.O., Genel, K., Buckling behavior of fiber reinforced plastic-metal hybrid-composite beam (2013) Mater Des, 49, pp. 130-138; Rafiee, R., On the mechanical performance of glass-fibre-reinforced thermosetting-resin pipes: A review (2016) Compos Struct, 143, pp. 151-164; Eyer, G., Montagnier, O., Charles, J.P., Hochard, C., Design of a composite tube to analyze the compressive behavior of CFRP (2016) Compos A Appl Sci Manuf, 87, pp. 115-122; Sino, R., Baranger, T.N., Chatelet, E., Jacquet, G., Dynamic analysis of a rotating composite shaft (2008) Compos Sci Technol, 68, pp. 337-345; Kotynia, R., Cholostiakow, S., New Proposal for Flexural Strengthening of Reinforced Concrete Beams Using CFRP T-Shaped Profiles (2015) Polymers-Basel, 7, pp. 2461-2477; Khalid, Y.A., Mutasher, S.A., Sahari, B.B., Hamouda, A.M.S., Bending fatigue behavior of hybrid aluminum/composite drive shafts (2007) Mater Des, 28, pp. 329-334; Ding, Z., Weeger, O., Qi, H.J., Dunn, M.L., 4D rods: 3D structures via programmable 1D composite rods (2018) Mater Des, 137, pp. 256-265; Mutasher, S.A., Prediction of the torsional strength of the hybrid aluminum/composite drive shaft (2009) Mater Des, 30, pp. 215-220; Misri, S., Sapuan, S.M., Leman, Z., Ishak, M.R., Torsional behaviour of filament wound kenaf yarn fibre reinforced unsaturated polyester composite hollow shafts.

With the increase in the highway load, the shear capacity of hollow slab bridges constructed before the 1990s can no longer meet the requirements of new safety regulations. Further research on the shear capacity of PC hollow slabs is necessary to ensure their safety, as these bridges continue to be operational. In this study, twelve hollow slabs with spans of 20 m, 16 m, and 10 m were tested to determine the shear performance of existing PC hollow slabs. Some hollow slabs were reinforced with a 15-cm thick concrete layer on the top surface to determine its effect on the shear capacity. The load-displacement curve, web strain, cracking and ultimate loads, and cracking and failure mode of the hollow slab were experimentally determined. The finite element method was used to simulate the shear process. The results show that the 10-m hollow slabs exhibited bending-shear failure, the 16-m hollow slabs exhibited shear compression failure, and the 20-m hollow slabs exhibited diagonal compression failure. Abdominal shear oblique cracks occurred on the webs of the hollow slabs with spans of 16 m and 20 m, whereas bending shear oblique cracks were formed in the 10-m hollow slabs. With post-casting of the 15-cm thick concrete layer, the cracking loads of the hollow slabs with spans of 10 m, 16 m, and 20 m increased by 47%, 32%, and 8%, whereas the ultimate loads increased by 41%, 22%, and 18%, respectively. A comparison of the results calculated based on design specifications and the test results shows that the design provisions for specifications related to the shear capacity are highly conservative. Finally, the conventional formula for the shear capacity was modified, and new formulas were proposed based on the test results and numerical simulation results to predict the shear capacities of the 10-m and 16-m/20-m PC hollow slabs. For these hollow slabs, the mean ratios of the calculated value to the experimental/simulated value obtained using the proposed formulas are 0.993 and 0.956, and the variances are 0.005 and 0.013, respectively. © 2020 Elsevier Ltd","Bridge engineering; Experimental study; Modified formula; Numerical simulation; Prestressed concrete (PC) hollow slab; Shear performance","Bridge decks; Computer simulation; Failure (mechanical); Highway bridges; Numerical models; Prestressed concrete; Safety engineering; Specifications; Bridge engineering; Experimental study; Hollow slabs; Modified formula; Shear performance; Shear flow; bridge; computer simulation; concrete; crack; displacement; experimental study; performance assessment; shear; structural component; China",,,,,"2018B49; National Natural Science Foundation of China, NSFC: 51878099; Chongqing Basic and Frontier Research Project: cstc2015jcyjys0011","The authors express their sincere gratitude for the financial support provided by the National Natural Science Foundation of China ( 51878099 ), the Chongqing Basic and Frontier Research Projects of China ( cstc2015jcyjys0011 ) and the Shandong Traffic Science and Technology Projects of China ( 2018B49 ).","This work was supported by the National Natural Science Foundation of China ( 51878099 ), the Chongqing Basic and Frontier Research Projects of China ( cstc2015jcyjys0011 ) and the Shandong Traffic Science and Technology Projects of China ( 2018B49 ).",,,,,,,,,"CCCC Highway Consultants CO Ltd., (2015), http://product.dangdang.com/23808923.html, General specifications for design of highway bridges and culverts (JTG D60-2015).

However, the torsional stiffness of SBMC-CBGCSW is dramatically decreased due to the employment of thin corrugated steel webs (CSWs). Investigations of SBMC-CBGCSW under pure torsion are relatively limited, therefore, additional research is needed to investigated to guarantee the safety of such bridges. In this paper, an experimental study on four scaled specimens subjected to pure torsion is conducted to understand the effect of the number of cells and spacing of CSWs on the full torsional response of SBMC-CBGCSW. The failure mode, cracking patterns, and buckling patterns of specimens are presented, and a new shear strain relationship between CSWs obtained from experimental results is proposed to evaluate the contribution of inner CSWs to the torsional behavior of SBMC-CBGCSW. Then, finite element analysis (FEA) models are created to compare with experimental results, such as torque-twist curves, shear strains of CSWs and shear strains of concrete slabs. Finally, a parametric study is performed to examine the effect of geometric factors, such as the ratio of width to height, ratio of width to span length, ratio of width to thickness of slab, number of cells and spacing of CSWs, on such bridges under torsion. © 2020 Elsevier Ltd","Corrugated steel webs; Experiment; FEA; Parametric study; Single-box multi-cell; Torsional response","Cells; Concrete slabs; Cytology; Experiments; Finite element method; Shear strain; Steel beams and girders; Torsional stress; Composite box girder; Corrugated steel webs; Experimental and numerical studies; Multicell; Parametric study; Torsional behaviors; Torsional response; Torsional stiffness; Box girder bridges",,,,,"National Natural Science Foundation of China, NSFC: 51878151","This work was supported by the National Natural Science Foundation of China [grant 51878151 ].

Previous studies have shown that the fatigue behavior of hot-riveted connections depends on many factors; among these, the residual tensile force in the rivets that clamps the plates together, i.e. the clamping force, is one of the most prone to uncertainty and scatter. Investigations p in the past made use of specimens produced in controlled laboratory conditions, potentially leading to optimistic results. This paper presents an experimental investigation on the clamping force of as-built hot-driven rivets extracted from an old steel bridge. On average, the clamping stress was found to be ∼100 MPa and ∼60 MPa, but with large scatter, for two or three plates being clamped, respectively, and for grip length over diameter ratios close to unity. This significant dependency on the number of clamped plates, as well as the lower values observed as compared to earlier studies, are attributed to larger imperfections in rivets installed in-service, as compared to the controlled laboratory environment. In addition, a finite element model is presented that simulates the development of the clamping force following the installation of the rivet. The finite element model was validated on the basis of the experimental data and it appears able to predict the effect of the grip length on the clamping force. The larger the grip length over diameter ratio, the larger is the clamping force. © 2020 The Authors","Clamping force; Clamping stress; Hot riveting process; Iron and steel bridges; Steel rivets","Clamping devices; Finite element method; Rivets; Steel bridges; Clamping Force; Clamping stress; Controlled laboratories; Experimental investigations; Iron and steel; Old steel bridges; Riveted connections; Riveting process; Fatigue of materials",,,,,,,,,,,,,,,,"Collette, Q., Sire, S., Vermes, W.J., Mesler, V.J., Wouters, I., Experimental investigations on hot-driven structural rivets in historical French and Belgian wrought-iron structures (1880s–1890s) (2014) Constr.

Specifically, linear-elastic analysis can be sensitive to material properties, geometry, and support settlements, while also allowing the development of tensile stresses that may be unrealistic for masonry structures. However, even though linear-elastic methods remain appealing for their simplicity, it is rare to evaluate their output against experimental data. In this paper, detailed strain and displacement monitoring data for a masonry arch viaduct are used to evaluate a series of independently developed linear-elastic simulations of this structure. Although uncertainties in input parameters mean the magnitude of modeling results cannot be presumed accurate, the simulated response pattern was found to agree reasonably well with monitoring data in regions of low damage. However, more damaged regions produced a markedly different local response. Comparisons between the simulations revealed useful conclusions regarding common modeling assumptions, namely the importance of modeling backing material, spandrels, and foundation stiffness, to capture their influence on the arch response. © 2019 American Society of Civil Engineers.","Finite-element modeling; Masonry arch; Structural health monitoring","Arches; Masonry bridges; Masonry construction; Masonry materials; Monitoring; Structural health monitoring; Uncertainty analysis; Displacement monitoring; Foundation stiffness; Linear elastic analysis; Linear elastic finite element analysis; Masonry arch bridges; Masonry arches; Masonry structures; Simulated response; Finite element method",,,,,"Engineering and Physical Sciences Research Council, EPSRC: EP/I019308/1, EP/K000314/1, EP/L010917/1, EP/N021614/1; EPSRC Centre for Doctoral Training in Medical Imaging","This work forms part of a PhD, which is funded through an EPSRC Doctoral Training Partnership (Grant No. EP/M506485/1).

Single lap bonded joints with three different ply thicknesses of 200 μm, 100 μm and 50 μm were tested under quasi-static tensile loading. Acoustic Emission and Digital Image Correlation were used to monitor the damage and strain evolution of the overlap area during testing. 3D post-mortem failure analysis of the fracture surfaces were performed using a 3D profiling microscope. Experimental results show an increase of 16% in the lap shear strength and an increase of 21% in the strain energy when using the 50 μm instead of 200 μm ply thicknesses. However, Acoustic Emission measurements show that the damage initiation is postponed up to a 47% higher load when using 50 μm instead of 200 μm ply thicknesses. Moreover, the total amount of acoustic energy released from initiation up to final failure was significantly less with thin plies. A non-linear finite element analysis up to damage initiation indicates that with decreasing ply thickness, the damage onset inside the composite is postponed to higher loads and moves away from the adhesive interface towards the mid-thickness of the adherend. It is found that, decreasing the single ply thickness of laminated composite adherends in a single overlap bonded joint increases the maximum load and delays damage initiation of the joint, however the damage progression till final failure is more sudden. © 2019 The Authors","Acoustic emission; Damage tolerance; Joints/joining; Thin-ply composites","Acoustic emissions; Adhesive joints; Adhesives; Bridge decks; Carbon fiber reinforced plastics; Damage tolerance; Laminated composites; Polymers; Reinforcement; Strain energy; Tensile strength; Acoustic emission measurement; Adhesive interfaces; Carbon fiber reinforced polymer; Digital image correlations; Joints/joining; Non-linear finite-element analysis; Ply composites; Single-lap bonded joints; Acoustic emission testing",,,,,"Nederlandse Organisatie voor Wetenschappelijk Onderzoek, NWO: 14366","This work has been funded by the Netherlands Organisation for Scientific Research (NWO) , project number 14366 .","This work has been funded by the Netherlands Organisation for Scienti?c Research (NWO), project number 14366.",,,,,,,,,"Amacher, R., Cugnoni, J., Botsis, J., Sorensen, L., Smith, W., Dransfeld, C., Thin ply composites: experimental characterization and modelingof size-effects (2014) Compos Sci Technol, 101, pp. 121-132; Camanho, P.P., Dávila, C.G., Pinho, S.T., Iannucci, L., Robinson, P., Prediction of in situ strengths and matrix cracking in composites under transverse tension and in-plane shear (2006) Composites Part A, 37, pp. 165-176; Sihn, S., Kim, R.Y., Kawabe, K., Tsai, S.W., Experimental studies of thin-ply laminated composites (2007) Compos Sci Technol, 67, pp. 996-1008; Yokozeki, T., Aoki, Y., Ogasawara, T., Experimental characterization of strength and damage resistance properties of thin-ply carbon fiber/toughened epoxy laminates (2008) Compos Struct, 82, pp. 382-389; Arteiro, A., Catalanotti, G., Melro, A.R., Linde, P., Camanho, P.P., Micro-mechanical analysis of the in situ effect in polymer composite laminates (2014) Compos Struct, 116, pp. 827-840; Cugnoni, J., Amacher, R., Kohler, S., Brunner, J., Kramer, E., Dransfeld, C., Smith, W., Botsis, J., Towards aerospace grade thin-ply composites: effect of ply thickness, fiber, matrix and interlayer toughening on strength and damage tolerance (2018) Compos Sci Technol, 168, pp. 467-477; ASTM-D3039M, Standard test method for tensile properties of polymer matrix composite materials (2014), ASTM International, American Society for Testing and Materials West Conshohocken, PA, USA; ASTM-D3518M, Standard test method for in-plane shear response of polymer matrix composite materials by tensile test of a ±45° laminate (2013), ASTM International, American Society for Testing and Materials West Conshohocken, PA, USA; ASTM-D6641M, Standard test method for compressive properties of polymer matrix composite materials using a combined loading compression test fixture (2014), ASTM International, American Society for Testing and Materials West Conshohocken, PA, USA; (2017) Material datasheet: ThinpregTM 135, , NTPT; Teixeira de Freitas, S., Sinke, J., Failure analysis of adhesively-bonded metal-skin-to-composite-stiffener: effect of temperature and cyclic loading (2017) Compos Struct, 166, pp. 27-37; datasheet, M., (2009) Scotch-WeldTM structural adhesive film AF, vols. 163–2; Kaw, K., Mechanics of composite materials (2006), Taylor & Francis Boca Raton; ASTM-D5868, Standard test method for lap shear adhesion for fiber reinforced plastic (FRP) bonding (2014), ASTM International, American Society for Testing and Materials West Conshohocken, PA, USA; (1987) Ultraviolet-ozone surface treatment, , Three Bond Technical News; Poulis, J.A., Small cylindrical adhesive bonds.

Based on the beam element model accounting for warping and flexural–torsional coupling, analytical solutions for different boundary conditions are derived for higher free vibration modes in bending, torsion and flexural–torsional coupled modes. In the model, the effects of rotational inertial kinematic terms are considered. The finite element approach of the model is also investigated. Three-dimensional beams with seven degrees of freedom per node are adopted in the mesh process. Free vibration and forced vibration analyses are possible. In forced vibration, the behaviour of the beams is studied in the frequency domain using the steady-state method (modal analysis). Damping is considered using the Rayleigh model. The model is validated by comparing the results to benchmark solutions found in the literature and to other recent numerical and experimental results. Additional finite element simulations are performed by means of commercial softwares (Abaqus and Adina). In slender unrestrained beams, the vibration behaviour is predominated by torsion and lateral bending modes. In design, recourse to braces is a good compromise. This solution is discussed, and improvement of the vibration behaviour in the presence of intermediate braces is confirmed. Application of higher vibration modes in building and bridge design is outlined. The effects of the number and distribution of the intermediate braces to improve structural stability against vibration behaviour is outlined. © The Author(s) 2019.","arbitrary section; bracing; finite element method;

Several empirical relations have been used to calculate the vertical stiffness of the elastomeric bearing systems, although, in certain conditions such as the presence of rotation, these relations are not accurate enough. In this paper, by using a nonlinear finite element program, the effect of rotation on the vertical stiffness investigated. It was observed that the vertical stiffness of the isolator could be increased or decreased depending on the amount of rotation and the value of lateral displacement limit. © 2019 Elsevier Ltd","Bearing rotation; Elastomeric bearing; Finite element; Lateral displacement; Vertical stiffness","Bridge bearings; Finite element method; Rotation; Base isolation; Elastomeric bearing; Empirical relations; Lateral displacements; Nonlinear finite element program; Vertical stiffness; Stiffness",,,,,,,,,,,,,,,,"Staudacher, E., Habacher, C., Siegenthaler, R., Erdbebensicherung in Baum (1970), Neue Zürcher Zeitung.

The UHPC plate in the composite deck featured by the favorable tensile performance and small thickness helps achieving a light self-weight. However, it results to a limited short space for the shear connector to transfer the interlayer shear force. Therefore, this study proposed a kind of short steel channel-section connector for the composite deck with a thin UHPC plate, and investigated its mechanical behavior through push-out tests and parametric FEM analysis. The test results showed the deformation of the channel connector during the loading process generally included the elastic, elastic–plastic, and plastic stages, and the shear fracture of channel connector dominated in the failure mode. The shear stiffness of the specimen with embedded reinforcement was increased by 39%, but had little influence on the shear capacity. On the other side, the parametric analysis told that the shear strength of connector increased significantly as the connector height increased from 50 to 80 mm. Nevertheless, the connector arrangement direction was a sensitive factor to the uplift resistance of the connector. © 2019, Korean Society of Steel Construction.","Channel connectors; Composite deck; FEM analysis; Push-out test; Shear behaviors; UHPC","Bridge decks; Composite decks; FEM analysis; Push-out tests; Shear behavior; UHPC; High performance concrete",,,,,"18PJ1410300; National Natural Science Foundation of China, NSFC: 51478120","This research was funded by the National Natural Science Foundation of China (No. 51478120).

Medvedeva 14, Niš, 18000, Serbia","A characteristic engineering example of the model presented in this paper, which consists of a viscoelastically and nonlinearly coupled beam-arch system, can be found in the physical model of a bridge. Here, the beam analogue of von Kármán's nonlinear strain-displacement relationships is used. After that the p-version of the finite element method is employed for the coupled system's geometrically nonlinear responses. In order to investigate the features of the arch's curvatures, a nonlinear analysis is performed in the time domain by the Newmark method and in the frequency domain by harmonic balance and continuation methods. The main contribution of the work is the discovery that the upper excited beam (in a double-beam model) goes back to the amplitude-symmetric vibration regime (as in the case of an excited single beam model) only if the lower beam is curved for the same excited scenario. That phenomenon comes from the nonlinear couplings in the beam-arch system and cannot be detected in the linear regime, while its existence is not evident without the analysis presented in this paper. Therefore, the non-symmetric higher amplitude deviations in the steady state regime of vibrations of the upper beam are transferred to the lower beam, only if the latter is curved. The paper shows that this nonlinear phenomenon is a consequence of 1:3 and 1:5 internal resonances where the first and the third/fifth modes become coupled. The most important purpose of the study lies in the clear physical insight into the nonlinear stabilizing benefits and the appearance of the nonlinear dynamic absorption or decrease in the excited beam amplitudes with determined amplitude-frequency responses, time histories, phase plots and deformed shapes for each particular case. In addition, by applying the Richardson extrapolation method within the standard Newmark procedure, an improvement is also explained and presented. The results of all these analyses are very valuable and have a wider application in vibrations. © 2019 Elsevier Ltd","Beam-arch system; Curvature effect; Improved Newmark method; Nonlinear vibrations","Arch bridges; Arches; Frequency response; Nonlinear analysis; Vibration analysis; Amplitude frequency response; Arch systems; Curvature effect; Newmark methods; Non-linear strain-displacement relationships; Non-linear vibrations; P-version of the finite-element method; Richardson extrapolation; Time domain analysis",,,,,"Natural Sciences and Engineering Research Council of Canada, NSERC; Ministarstvo Prosvete, Nauke i Tehnološkog Razvoja, MPNTR: ON 174011, ON 174013","The authors would like to acknowledge the help provided by the Ministry of Education, Science and Technological Development of the Republic of Serbia through the grants ON 174011 and ON 174013 , and in part by the Natural Sciences and Engineering Research Council of Canada .",,,,,,,,,,"Petyt, M., Fleischer, C., Free vibration of a curved beam (1971) J.

This study was conducted to investigate the effect of human induced vibrations on common simply supported steel footbridges in Jordan, especially those with natural frequencies between 2 to 4 Hz. Such fundamental frequency is close to human movement frequency of walking, jumping and running. The ETABS software was utilized to develop a finite element model (FEM) in order to identify the footbridge dynamic properties including frequency, natural period, stiffness and the critical length at which the induced-vibrations become of great effect. The bridge was excited with multiple human walking and running loading scenarios. The response of the footbridge was evaluated and compared with and without integrating tuned mass dampers (TMD) tuned with the fundamental natural frequency of the footbridge in order to optimize appropriate mass, stiffness and damping coefficient. It was observed that after attaching the TMD, the fundamental vibration frequency decreased to stable value less than human excitation frequencies. Also, acceleration, velocity, and displacement responses were decreased significantly to be within acceptable limits. Finally, a recommendation and guidelines are given for considering the induced-vibrations in the design of common footbridges in Jordan. © 2020 The Authors.","Dampers; FEM; Footbridges; TMD; Vibrations",,,,,,,,,,,,,,,,,"(2019) Footbridge, , https://en.wikipedia.org/wiki/Footbridge, En.wikipedia.org (Accessed: 29 July 2019); Pat, D., London Millennium Bridge: Pedestrian-Induced Lateral Vibration (2001) Journal of Bridge Engineering.

Although such a perspective has been adopted to some extent for buildings and bridges, there is a gap in the body of knowledge concerning how this can be extended to the structures that support highway signs, luminaries, and traffic signals. This gap motivated the current study to investigate the fatigue performance of steel Dynamic Message Sign (DMS)-support structures under the effects of both diurnal temperature changes and natural wind excitations. Upon recording the necessary field data for one year, detailed information for a variety of parameters that contribute to the fatigue life of DMS-support structures was obtained. The parameters of interest included strain, temperature, and wind speed and direction. The field monitoring program was then paired with rigorous finite-element (FE) simulations. After the validation of the developed FE models, individual and combined effects of the contributing stressors were quantified to understand the vulnerability of DMS-support structures to fatigue under multiple stressors of different nature. This led to the identification of the most fatigue-critical elements, which vary based on temperature and wind load effects. The study was then extended to use historical temperature and wind data to evaluate long-term environmental effects.

Thermo-elasto-plastic and metallurgical analyses are carried out by developing two user-defined subroutines: one for applying the heat flux and the another one for considering phase transformation effects on welding residual stresses. The applied heat flux is simulated by a double ellipsoid model. Furthermore, the effects of volumetric change due to the solid-state austenite-martensite transformation are taken into account. The results obtained have revealed that volumetric change owing to the solid-state austenite-martensite transformation has a significant effect on the magnitude and distribution of welding residual stresses. The main contribution of the present work is providing helpful knowledge about welding residual stresses evolution after and before the post-weld heat treatment by considering the solid-state austenite-martensite transformation. In addition to reference to the time–temperature–transformation diagram, this study can result in safe selection of post-weld heat treatment parameters, which not only prevents sensitization to stress corrosion cracking and intergranular corrosion but also provides enough and more importantly controlled relaxation of welding residual stresses. © IMechE 2019.","austenite-martensite transformation;

There are two approaches to calculate the reliability curves as a function of the traditional/global factor of safety in the literature. However, it is not clear how these two approaches may be related and why. This paper is devoted to answering this question, through the aid of an implemented auto-search algorithm within the strength reduction method and the quantification of the potential sliding volumes in the various possible Monte Carlo realisations of the soil spatial variability. The equivalences and differences between the two approaches, and thereby their respective merits and disadvantages, are explained and discussed for the most commonly used distribution types of soil strength properties, that is, normal and lognormal distribution. Computational efficiency has also been addressed in the form of pseudocodes, which can be readily implemented. © 2019 by the authors.","Finite element; Probability of failure; Reliability; Slope stability; Spatial variability; Strength reduction method",,,,,,"National Natural Science Foundation of China, NSFC: 41807228; Ministry of Water Resources, MWR: YK319004; National Key Research and Development Program of China, NKRDPC: 2017YFC0405104, 51979173; Fundamental Research Funds for the Central Universities: 2652017071","This research was funded by the National Natural Science Foundation of China, grant number 41807228; the Fundamental Research Funds for the Central Universities, grant number 2652017071; and the Open Foundation of Key Laboratory of Failure Mechanism and Safety Control Techniques of Earth-Rock Dam of the Ministry of Water Resources, grant number YK319004.

However, an updated baseline finite element model (FEM) is normally required to quantify damages for such an approach. A two-stage damage detection procedure is presented for bridges by utilizing the mode shape estimated from a moving vehicle. Damage locations are first determined through a damage localization index (DLI) defined by regional mode shape curvature (RMSC). Then the relationship between the damage extents and the RMSC changes is investigated by FEM simulation. Finally, an equation set to quantify the single and multiple damages is deduced by combining the RMSCs and the relationship between the damage extents and the RMSC changes established by an un-updated FEM. Numerical and experimental examples are carried out to verify the validity and efficiency of the two-stage method. The results revealed that it can localize and quantify damages with satisfactory precision by using the response measured from one sensor only. © 2019 World Scientific Publishing Company.","Damage localization; damage quantification; mode shape; moving vehicle","Finite element method; Numerical methods; Structural analysis; Tunneling (excavation); Vehicles; Damage localization; Damage quantification; High spatial resolution; Mode shape curvatures; Mode shapes; Moving vehicles; Structural damage localization; Two-stage methods; Damage detection",,,,,"National Natural Science Foundation of China, NSFC: 51778204, 51878234; Fundamental Research Funds for the Central Universities: JZ2019HGPA0101, PA2017GDQT0022","This research is supported by the National Natural Science Foundation of China (Project Nos. 51878234 and 51778204) and Fundamental Research Funds for the Central Universities (Nos.

Analytical expressions for the displacement field of the track slab during the warping process are developed hereby based on equilibrium differential equations, and the expressions are verified through a numerical model by finite element method in ANSYS package. Through analyzing the factors such as types of temperature distribution, slab gravity, and rail weight, regulations of warping deformation for the track slab are systematically analyzed. Research shows that the displacements in the x and z directions are linearly related to the respective components during the warping deformation. The displacement in y direction has a quadratic relationship with x and z components. Temperature gradient is the pivotal factor to lead the warping of the track slab, and the type of temperature distribution has less effect on the warping displacement. If track slab remains unwarped under the effect of slab gravity, temperature gradient should be maintained in the range of –18°C/m–13°C/m. Rail weight has less influence on slab warping. © The Author(s) 2019.","ballastless track; equilibrium differential equations; longitudinally coupled prefabricated slab track; slab warping; temperature gradient","Box girder bridges;

For satisfying the robustness of the rotating body and improving the torque density, we propose a structure in which two types of cores with different shapes are cross laminated. The proposed rotor structure consists of a core with a bridge that is necessary to maintain the rigidity of the rotor assembly, and a rotor assembly by cross laminating the segment-type rotor cores necessary for minimizing the leakage flux as well as improving the torque density. The complex three-dimensional (3-D) magnetic circuit of the cross-laminated rotor assembly has been modeled as a two-dimensional (2-D) model on the mathematical basis of an equivalent magnetic circuit. Using the equivalent 2-D model, the design of the cross-laminated rotor shape and the electromagnetic characteristics were examined comprehensively. At the same time, mechanical stresses due to centrifugal force and torque transmission between rotor core and shaft were examined. Finally, after the prototype was fabricated, the analysis and design methods were verified through no-load and load tests. © 2019 IEEE.","Cross-laminated rotor; equivalent two-dimensional (2-D) model; ferrite magnet; finite element analysis; flux concentrated rotor; leakage flux; mechanical stress","Equivalent circuits; Ferrite; Finite element method; Magnetic circuits; Magnetic cores; Magnetic leakage; Structural design; Torque; Cross laminated; Cross-laminated rotor; Equivalent two-dimensional (2-D) model; Ferrite magnet; Finite element analyse; Flux concentrated rotor; Laminated rotors; Leakage flux; Mechanical stress; Two-dimensional (2-D) model; Permanent magnets",,,,,"TEC-01027-2018","Manuscript received October 11, 2018; revised January 8, 2019 and January 30, 2019; accepted February 1, 2019.

Timber is an anisotropic material and is not fire resistant. Also, moisture causes significant swelling. So, structural behavior should be carefully evaluated by experimental techniques before and after restoration and verified numerically using finite element models. This article presents a detailed study on the structural condition assessment of a restored historical timber mosque: its finite element analysis (FEA), ambient vibration tests, model updating to minimize the differences and reflect the current situation, and dynamic analyses before and after updating procedure. The Kuşluca historical timber mosque located in the Sürmene District of Trabzon, Turkey was selected as an application. The mosque was built in the early 20th century and includes two floors. Significant timber decorative elements are available in the entrance door, minbar, and mihrab. The restoration projects began in 2008, and the restored mosque was opened in 2011. Finite element modeling of the mosque was accomplished using SAP2000 software (Computers and Structures, Inc., Walnut Creek, California), considering the restoration project drawings. Modal analysis was performed using orthotropic material properties, considering literature review, to determine the initial dynamic characteristics. Nondestructive experimental measurements were conducted after construction to validate the numerical results using in situ testing. Ambient vibration-based system identification was employed using the Enhanced Frequency Domain Decomposition method in the frequency domain and Stochastic Subspace Identification method in the time domain. The first three natural frequencies were obtained between 5.160 Hz to 7.153 Hz and 3.960 Hz to 5.873 Hz numerically and experimentally, respectively. There is close agreement between mode shapes, but 30.0 % differences in natural frequencies. To minimize the differences, the finite element model of the timber mosque is updated using the manual model updating procedures, with a changing of material properties to reflect the real structural behavior. The maximum differences are reduced to below the acceptable limits as 5 %. To evaluate the structural behavior and determine the model updating effect, linear dynamic-time history analyses are performed, and displacements with internal forces are compared to each other. © 2019 ASTM International.

This study investigates dynamic responses of a long-span, rail-cum-road cable-stayed bridge under ship collision through finite element analysis. Three ship tonnages were investigated, which are 3000, 5000, and 8000 t, respectively. The displacement, velocity, and acceleration of the bridge under ship collision are analyzed. The collision process is simulated in two explicit steps to improve the computational efficiency. First, the collision force is determined through a collision simulation of the ship to a rigid body that simulates the massive bridge pier. The collision force is then applied to the bridge to analyze the dynamic responses of the bridge. The simulation results of the collision force are compared with four different design codes. Analysis results from different codes show significant discrepancies, demonstrating lack of reliability of the formula recommended by the codes. The results indicate that the maximum displacement and acceleration occur at the top of the bridge pylon. The bridge’s responses under ship collision decrease as the collision angle increases from 0° to 20°. © The Author(s) 2019.","collision angle; dynamic response; finite element method; long-span bridge;

When liquefaction occurs, the strength of the soil decreases, which may cause trains to derail during earthquakes. This study establishes a three-dimensional two-stage finite element procedure to analyze train derailment behavior during earthquakes under soil liquefaction conditions. In the first stage, a cuboid soil profile is used to simulate the displacement and water pressure fields. Then, the train derailment model using p-y, t-z, and Q-z curves for soil is analyzed, and the displacements obtained from the first stage are added into the p-y, t-z, and Q-z elements to simulate the earthquake motion. The capacities of the p-y, t-z, and Q-z elements are reduced due to excess pore water pressure. Thus, the derailment coefficient of each wheel of the train can be obtained appropriately. Finally, the finite element results indicate that the wheel derailment coefficients with soil liquefaction are greater than those without soil liquefaction for the most of the seismic load time periods. © 2019 Elsevier Ltd","Bridge; Derailment; Earthquake; Finite element method; Moving wheel axis element; Pore water pressure; Soil liquefaction; Train","Bridges; Derailments; Earthquakes; Finite element method; Pore pressure; Pressure distribution; Soils; Water; Wheels; Derailment coefficient; Earthquake motion; Excess pore water pressure; Finite element procedure; Moving wheel axis element; Pore-water pressures; Train; Wheel derailment; Soil liquefaction; bridge; earthquake engineering; finite element method; liquefaction; pore pressure; porewater; train",,,,,,,,,,,,,,,,"Mohanty, P., Dutta, S.C., Bhattacharya, S., Proposed mechanism for mid-span failure of pile supported river bridges during seismic liquefaction (2017) Soil Dynam Earthq Eng, 102, pp. 41-45; McGann, C.R., Arduino, P., Numerical assessment of the influence of foundation pinning, deck resistance, and 3D site geometry on the response of bridge foundations to demands of liquefaction-induced lateral soil deformation (2015) Soil Dynam Earthq Eng, 79, pp. 379-390; Franke, K.W., Rollins, K.M., Lateral Spread Displacement, Foundation, B., Case histories from the 1991 magnitude 7.6 earthquake near limon (2017), p. 143. , J Geotechnical and Geoenvironmental Eng Costa Rica (6):05017002; Mondal, G., Rai, D.C., Performance of harbor structures in andaman Islands during 2004 sumatra earthquake (2008) Eng Struct, 30 (1), pp. 174-182; Ju, S.H., A simple finite element for nonlinear wheel/rail contact and separation simulations (2014) J Vib Control, 20 (3), pp. 330-338; Yang, Y.B., Wu, Y.S., Dynamic stability of trains moving over bridges shaken by earthquakes (2002) J Sound Vib, 258 (1), pp. 65-94; Tanabe, M., Matsumoto, N., Wakui, H., Sogabe, M., Okuda, H., Tanabe, Y., A simple and efficient numerical method for dynamic interaction analysis of a high-speed train and railway structure during an earthquake (2008) J Comput Nonlinear Dyn, 3 (4). , 041002; Jin, Z.B., Pei, S.L., Li, X.Z., Liu, H.Y., Qiang, S.Z., Effect of vertical ground motion on earthquake-induced derailment of railway vehicles over simply-supported bridges (2016) J Sound Vib, 383, pp. 277-294; Wu, X.W., Chi, M.R., Gao, H., Post-derailment dynamic behaviour of a high-speed train under earthquake excitations (2016) Eng Fail Anal, 64, pp. 97-110; Ju, S.H., Improvement of bridge structures to increase the safety of moving trains during earthquakes (2013) Eng Struct, 56, pp. 501-508; Bessason, B., Haflidason, E., Recorded and numerical strong motion response of a base-isolated bridge (2004) Earthq Spectra, 20 (2), pp. 309-332; Jara, M., Casas, J.R., A direct displacement-based method for the seismic design of bridges on bi-linear isolation devices (2006) Eng Struct, 28 (6), pp. 869-879; Jangid, R.S., Equivalent linear stochastic seismic response of isolated bridges (2008) J Sound Vib, 309 (3-5), pp. 805-822; Jara, M., Jara, J.M., Olmos, B.A., Improved procedure for equivalent linearization of bridges supported on hysteretic isolators (2012) Eng Struct, 35, pp. 99-106; Zienkiewicz, O.C., Shiomi, T., Dynamic behavior of saturated porous-media - the generalized Biot formulation and its numerical-solution (1984) Int J Numer Anal Methods Geomech, 8 (1), pp. 71-96; Land, L., Dobry, R., Effect of liquefaction on lateral response of piles by centrifuge model tests (1995) NCEER Bull, 9 (1), p. 87; Brandenberg, S.J., Behavior of pile foundations in liquated and laterally spreading ground (2005), PhD thesis University of California Davis; Chang, B.J., Hutchinson, T.C., Experimental evaluation of p-y curves considering development of liquefaction, J Geotechnical and Geoenvironmental Engineering (2013) ASCE, 139 (4), pp. 577-586; Dash, S., Rouholamin, M., Lombardi, D., Bhattacharya, S., A practical method for construction of p-y curves for liquefiable soils (2017) Soil Dynam Earthq Eng, 97, pp. 478-481; Idriss, I., Sun, J.L., SHAKE91––a computer program for conducting equivalent linear seismic response analyses of horizontally layered soil deposits, Center for Geotechnical Modeling (1992), University of California at Davis CA; Ju, S.H., Wang, Y.M., Time-dependent absorbing boundary conditions for elastic wave propagation (2001) Int J Numer Methods Eng, 50, pp. 2159-2174; Recommended practice for planning, designing, and constructing fixed onshore platforms – working stress design, RP 2A-WSD (2000), twenty-first ed.

According to the controversial behavior of these members under Christchurch earthquakes and experimental tests, the ultimate failure mode of the links revealed as web fracture which was different from dominant web buckling mode observed previously. First, the finite element model was verified by results of nine experimental studies conducted by other researchers. Then, to reassess shear link design criteria, 135 finite element specimens were evaluated. The experimental results were utilized for calibration of ductile fracture criteria under low and high triaxiality ratio to resolve finite element incapability of fracture prediction. The experimental links data base (43 links), which mostly meet design criteria, and parametric finite element models were used to reassess the accuracy of the shear links design criteria suggested by AISC. However, most of the shear links over-strength demonstrates a slight moment-shear interaction, but this is not a rational reason to neglect its effect on web fracture strain (domain). The main results show that while design criteria are conservative for most low and intermediate-depth links, they might not be as accurate as in the case of high-depth ones. Finally, the cumulative plastic strain distributions of the parametric studies were utilized to develop the schematic patterns when different boundary conditions exist. © 2019","Design criteria reassessment; High-depth links; Moment-shear interaction; Plastic strain domain; Shear link","Bridge decks; Concrete beams and girders; Ductile fracture; Earthquakes; Finite element method; Plastic deformation; Design criteria; Different boundary condition; Ductile fracture criterion; Eccentrically braced frames; High-depth links; Moment-shear interaction; Parametric finite elements; Shear link; Shear flow",,,,,,,,,,,,,,,,"Roeder, C.W., Popov, E.P., Eccentrically braced steel frames for earthquakes (1978) J.

Site-specific vehicle loads monitored by the weigh-in-motion system can assist to obtain the operational cyclic stresses of hangers. Differing from most existing studies, herein, a framework for fatigue performance investigation for hangers of suspension bridges is proposed utilizing the full information of the weigh-in-motion data. This framework includes four steps: (1) generate influence surfaces for hangers, (2) reconstruct vehicular loading flows based on the weigh-in-motion data, (3) calculate time histories of hanger tension forces, and (4) evaluate fatigue damages and predict fatigue lives. Critical issues, such as the loading configuration of trucks, the threshold of the gross vehicle weight, and the time step for stress calculation, have been studied and discussed in detail. Based on 8-month weigh-in-motion data of a prototype suspension bridge, it is shown that the fatigue damage of hangers can be evaluated day by day, and subsequently the fatigue lives can be predicted. The correlation between the fatigue damages and vehicular loads is also investigated in this study. © The Author(s) 2018.","fatigue damage; finite element analysis; hanger; influence surface; structural health monitoring; Suspension bridge; weigh-in-motion","Automobile suspensions; Fatigue damage; Finite element method; Loads (forces); Stress analysis; Structural health monitoring; Suspension bridges; Suspensions (components); Weigh-in-motion (WIM); Fatigue performance; Gross vehicle weight; hanger; Influence surfaces; Loading configuration; Stress calculations; Weigh-in-motion datum; Weigh-in-motion systems; Fatigue of materials",,,,,"National Natural Science Foundation of China, NSFC: 51308073, 51438002; Beijing University of Civil Engineering and Architecture, BUCEA: X18004","This work was supported by the National Natural Science Foundation of China (51438002 and 51308073) and the Fundamental Research Funds for Beijing University of Civil Engineering and Architecture (X18004).",,,,,,,,,,"Li, S., Zhu, S., Xu, Y.L., Long-term condition assessment of suspenders under traffic loads based on structural monitoring system: application to the Tsing Ma Bridge (2012) Struct Control Health Monit, 19, pp. 82-101; Chen, B., Li, X., Xie, X., Fatigue performance assessment of composite arch bridge suspenders based on actual vehicle loads (2015) Shock Vib, 2015, p. 659092; Takena, K., Miki, C., Shimokawa, H., Fatigue resistance of large-diameter cable for cable stayed bridges (1992) J Struct Eng: ASCE, 118 (3), pp. 701-715; Suh, J.I., Chang, S.P., Experimental study on fatigue behaviour of wire ropes (2000) Int J Fatigue, 22, pp. 339-347; Li, S., Xu, Y., Zhu, S., Probabilistic deterioration model of high-strength steel wires and its application to bridge cables (2015) Struct Infrastruct E, 11 (9), pp. 1240-1249; He, J., Zhou, Z., Ou, J., Optic fiber sensor-based smart bridge cable with functionality of self-sensing (2013) Mech Syst Signal Pr, 35, pp. 84-94; Bao, Y., Shi, Z., Beck, J.L., Identification of time-varying cable tension forces based on adaptive sparse time-frequency analysis of cable vibrations (2017) Struct Control Health Monit, 24, p. e1889; Feng, D.M., Scarangello, T., Feng, M.Q., Cable tension force estimate using novel noncontact vision-based sensor (2017) Measurement, 99, pp. 44-52; Guo, T., Frangopol, D.M., Chen, Y., Fatigue reliability assessment of steel bridge details integrating weigh-in-motion data and probabilistic finite element analysis (2012) Comput Struct, 112-113, pp. 245-257; Liu, Y., Zhang, H., Liu, Y., Fatigue reliability assessment for orthotropic steel deck details under traffic flow and temperature loading (2017) Eng Fail Anal, 71, pp. 179-194; Liu, Z., Guo, T., Chai, S., Probabilistic fatigue life prediction of bridge cables based on multiscaling and mesoscopic fracture mechanics (2016) Appl Sci, 6, p. 99; Liu, Z., Guo, T., Huang, L., Fatigue life evaluation on short suspenders of long-span suspension bridge with central clamps (2017) J Bridge Eng: ASCE, 22 (10), p. 04017074; Petrini, F., Bontempi, F., Estimation of fatigue life for long span suspension bridge hangers under wind action and train transit (2011) Struct Infrastruct E, 7 (7-8), pp. 491-507; Deng, Y., Liu, Y., Chen, S., Long-term in-service monitoring and performance assessment of the main cables of long-span suspension bridges (2017) Sensors, 17, p. 1414; Liu, Y., Deng, Y., Cai, C.S., Deflection monitoring and assessment for a suspension bridge using a connected pipe system: a case study in China (2015) Struct Control Health Monit, 22, pp. 1408-1425; (2015) General code for design highway bridges and culverts JTG D60-2015, , Beijing, China, China Communications Press; (2010) LRFD bridge design specifications, , Washington, DC, AASHTO; Ma, L., Han, W.S., Ji, B., Study of vehicle-bridge coupling vibration under actual traffic flow (2012) China J Highw Trans, 25 (6), pp. 80-87. , (,):, –, (in Chinese; Downing, S.D., Socie, D.F., Simplified rainflow cycle counting algorithms (1982) Int J Fatigue, 4, pp. 31-40; Miner, M.A., Cumulative damage in fatigue (1945) J Applied Mechanics, 12, pp. 159-164; Faber, M.H., Engelund, S., Rackwitz, R., Aspects of parallel wire cable reliability (2003) Struct Saf, 25 (2), pp. 201-225; Zeng, Y., Chen, A.R., Tang, H.M., Fatigue assessment of hanger wires of suspension bridges in its operation life based on in-situ traffic flow (2014) J Disaster Prev Mitig Eng, 34 (2), pp. 185-191. , (,):, –, (in Chinese; Hosford, W.F., (2005) Mechanical behavior of materials, , Cambridge, Cambridge University Press","Deng, Y.; Beijing Advanced Innovation Center for Future Urban Design, China; email: dengyang@bucea.edu.cn",,,"SAGE Publications Ltd",,,,,14759217,,,,"English","Struct.

The bridge was built at the end of the 19th century using the available technology of its time. It is composed of six spans, each 30 m long, with a total length of 180 m. It is slightly curved in the horizontal plane with a radius of 300 m, and has a vertical grade of 2.5%. Modal parameters of the bridge were estimated using two different output-only system identification methods. The identified results obtained under different temperature conditions were compared in assessing the effects of temperature variation in the identification results. A comparative study in assessing method-to-method and test-to-test variability was also conducted. A three-dimensional finite-element model of the bridge was developed. In order to match the experimentally obtained modal parameters with the numerical ones, a trial-and-error-based model updating study was conducted. This way, a benchmark model of the 199+325 steel railway bridge was obtained for future capacity assessment, prediction, and sensitivity-based model updating work. © 2019 American Society of Civil Engineers.","Ambient vibration tests; Finite-element model updating; Output-only system identification; Steel railway bridge; Temperature effects","Composite beams and girders; Finite element method; Modal analysis; Railroad bridges; Railroads; Religious buildings; Temperature; Thermal effects; Vibration analysis; Ambient vibration test; Effects of temperature; Finite-element model updating; Modal parameter estimation; Output only; Steel railway bridge; System identification methods; Three dimensional finite element model; Parameter estimation",,,,,"214M029","The authors greatly acknowledge the financial support provided by the Scientific and Technological Council of Turkey (TUBITAK) under Grant No. 214M029.

There exists complex cutting deformation, higher cutting temperature, higher cutting force and formation of serrated chip in the machining process. However, the formation time of every saw tooth unit in serrated chip is very short. It is difficult to use traditional method to analyze the chip at any time. Simulation analysis, integrated with the experimental results, was used to study the whole process of cutting deformation. The Johnson–Cook (JC) constitutive model of Inconel718 under high speed and high strain rate is established through split Hopkinson pressure bar (SHPB) test. The finite element method was used to study the deformation process. Combining the analysis of metallographic pictures which were obtained in the cutting experiment, the plastic behavior evolution of material in the cutting zone is deeply studied to further reveal the forming mechanism of serrated chip. The results showed that the local temperature in the cutting zone increased rapidly. The appearance of thermal softening of materials led to the change of stress distribution in the cutting zone. The thermoplastic shear instability further appeared which resulted in the shear localization, subsequently leading to the uneven deformation of chip and then serrated chip formed. © 2018 Politechnika Wrocławska","Adiabatic shear; Johnson–Cook model; Serrated chip; Split Hopkinson pressure bar (SHPB) test","Bridge decks; Constitutive models; Cutting; Deformation; Machining; Nickel alloys; Strain rate; Adiabatic shear; Cutting deformations; Deformation mechanism; Deformation process; Serrated chip; Shear localizations; Simulation analysis; Split Hopkinson pressure bars; Mechanical testing",,,,,"National Natural Science Foundation of China, NSFC: 51505038, 51605043; Education Department of Jilin Province: JJKH20170564KJ","This work is supported by National Natural Science Foundation of China ( 51505038 , 51605043 ) and Project of Jilin Provincial Education Department ( JJKH20170564KJ ).",,,,,,,,,,"Zhu, D.H., Zhang, X.M., Ding, H., Tool wear characteristics in machining of nickel-based superalloys (2013) Int.

However, the behavior of field-cast UHPC connections under temperature effects is not yet fully understood. Furthermore, the temperature distribution that produces the largest thermally induced stresses in UHPC connections is unknown. In this study, the thermally induced stresses in field-cast UHPC shear key connections in an adjacent precast prestressed concrete box beam bridge were investigated using field data as well as a three-dimensional finite-element (FE) model. The FE model was validated using field data and exhibited the ability to capture the behavior of the bridge. A new temperature distribution was noticed based on the data analysis. This temperature distribution has not yet been considered by professional bridge design specifications, although it produced the largest thermally induced stresses in UHPC connections and at the beam-key interface. The observed temperature distribution should be considered in the design of UHPC shear keys for these types of bridges. © 2018 American Society of Civil Engineers.","Adjacent box beam; Finite-element (FE) model; Shear key connection; Temperature; Thermal stress; Ultrahigh-performance concrete (UHPC)","Bridge decks; Compressive strength; Concrete beams and girders; Precast concrete; Prestressed concrete; Shear flow; Temperature; Temperature distribution; Tensile strength; Thermal stress; Box beam; Bridge connections; Concrete box beams; Shear key; Thermally induced; Thermally induced stress; Three dimensional finite elements; Ultra high performance concretes (UHPC); Finite element method",,,,,,,,,,,,,,,,"Aaleti, S., Honarvar, H., Sritharan, S., Rouse, M., Wipf, T., (2014) Structural Characterization of UHPC Waffle Bridge Deck and Connections, , IHRB Project TR-614.

In this study, a new design method of BPS was proposed based on the force analysis of supporting rings and bridges during stent implantation, and a novel BPS called open C-shaped stent (OCS) with superior comprehensive mechanical properties was developed accordingly. The key mechanical properties including radial force, radial recoil, and axial foreshortening of the OCS have been comprehensively studied and compared with those of the Abbott BVS using finite element analysis (FEA). In addition, the effects of the stent geometries on these mechanical properties have also been discussed in detail. Besides, in vitro mechanical tests including stent expansion and planar compression experiments have been performed to verify the simulation results. Based on the FEA results, it is found that the radial force and radial recoil of the designed OCS are 30% higher and 24% lower than those of the BVS, respectively. Meanwhile, the OCS is not shortened during expansion. Radial force and radial recoil are mainly dependent on the supporting ring structure, and the utilization of designed unequal-height supporting ring (UHSR) can effectively improve these two properties. Axial foreshortening is mainly determined by the bridge geometry as well as the connecting position of the bridge with the adjacent supporting rings. It is feasible to improve the axial foreshortening by using the bridges with a curved structure and locating the connecting position in the middle of the straight section of the supporting elements. The rationality of the proposed OCS and the effectiveness of the finite element method have been verified by in vitro experiments. © 2019 Yunbo Wei et al.",,"Biodegradable polymers; Finite element method; Mechanical properties; Stents; Structural design; Bridge geometry; Compression experiments; Curved structure; Design method; Force analysis; Ring structures; Stent geometry; Stent implantation; Bridges",,,,,"National Natural Science Foundation of China, NSFC: 51675079","This study was funded by the National Natural Science Foundation of China (51675079)",,,,,,,,,,"McKavanagh, P., Zawadowski, G., Ahmed, N., Kutryk, M., The evolution of coronary stents (2018) Expert Review of Cardiovascular Therapy, 16 (3), pp. 219-228. , 2-s2.0-85042142090; Tan, H., Ananthakrishna, R., A review of bioresorbable scaffolds: hype or hope?

The Bayesian framework for model parameter estimation, model selection, and robust predictions of output quantities of interest is first presented. Bayesian asymptotic approximations and sampling algorithms are then outlined. The framework is implemented for updating linear and nonlinear finite element models in structural dynamics using vibration measurements consisting of either identified modal frequencies or measured response time histories. For asymptotic approximations based on modal properties, the formulation for the posterior distribution is presented with respect to the modal properties of the reduced-order model. In addition, analytical expressions for the required gradients with respect to the model parameters are provided using adjoint methods. Two applications demonstrate that drastic reductions in computational demands can be achieved without compromising the accuracy of the model updating results. In the first application, a high-fidelity linear finite element model of a full-scale bridge with hundreds of thousands of degrees-of-freedom (DOFs) is updated using experimentally identified modal properties. In the second application, a nonlinear model of a base-isolated building is updated using acceleration response time histories. © 2019, Springer Nature Switzerland AG.",,"Approximation algorithms; Degrees of freedom (mechanics); Structural dynamics; Asymptotic approximation; Degrees of freedom (DoFs); Finite-element model updating; Linear finite element model; Model parameter estimation; Non-linear finite element model; Posterior distributions; Quantities of interests; Finite element method",,,,,,,,,,,,,,,,"Angelikopoulos, P., Papadimitriou, C., Koumoutsakos, P., Bayesian uncertainty quantification and propagation in molecular dynamics simulations: A high performance computing framework (2012) J.

The stress characteristics of welded details are analyzed using the finite element method. Based on the fatigue performance, the structural parameters of the orthotropic steel decks (OSDs) are optimized using the combination BP (back propagation) neural network and genetic algorithms (GA). The calculated results demonstrate that the weld stresses at the deck plate-to-rib, deck plate-to-rib-to-diaphragm welded details are mainly bending stress while those at the rib-to-rib welded details are mainly membrane stress. The fatigue stress of each weld is deeply affected by the transverse and longitudinal direction positions. The local effect of stress distribution of all welded details is remarkable. The calculated results obtained using the proposed model are in good agreement with those obtained using ANSYS and the errors are within 5%. The optimal structural results are highly influenced by the applied wheel loadings, while the optimal results for the deck thickness and the U-rib opening size are highly influenced by temperature. Especially on the ordinary lane, temperature has a great effect on the fatigue performance for all welded details. © 2019, Korean Society of Civil Engineers.","fatigue performance; orthotropic steel bridge decks; structural optimization; temperature; welded details","Backpropagation algorithms; Beams and girders; Box girder bridges; Bridge decks; Genetic algorithms; Plates (structural components); Structural optimization; Temperature; Welding; Welds; BP (back propagation) neural network; Fatigue performance; Longitudinal direction; Orthotropic steel box girders; Orthotropic steel bridge decks; Orthotropic steel decks; Stress characteristics; Welded details; Fatigue of materials",,,,,,,,,,,,,,,,"Zolfaghari, A., Bidar, S.A., Maleki Javan, M.R., Haftani, M., Mehinrad, A., Evaluation of rock mass improvement due to cement grouting by Q–system at Bakhtiary dam site (2015) International Journal of Rock Mechanics and Mining Sciences, 74, pp. 38-44; (1990) Guide specification for fatigue evaluation of existing steel bridge, American Association of State Highway and Transportation Officials; Chang, K.O., Bae, D., Proposed revisions to fatigue provisions of orthotropic steel deck systems for long span cable bridges (2014) International Journal of Steel Structures, 14 (4), pp. 811-819; Connor, R., Fisher, J., Gatti, W., Gopalaratnam, V., Kozy, B., Leshko, B., McQuaid, D.L., Paterson, D., (2012) Manual for design, construction, and maintenance of orthotropic steel deck bridges, Report No; (2005) Design of steel stuctures−Part 1–9.

With superior mechanical characteristics, this new material reduced the structural self-weight and extended the span of modern bridges. A series of tests should be conducted to establish reliable design rules for UHPFRC structures. This paper aimed at determining the compressive behavior of UHPFRC for thin-walled arch section design and a comparison was made with a normal concrete (NC) arch. Eighteen axial compression columns for arch section design and arches under asymmetric load were tested in this paper. Behaviors of the arches were assessed using various mechanical properties, including the failure pattern, load-deflection relationship, strain analysis, and analytical investigation. A finite element model (FEM) considering the material and geometric nonlinearity was developed to predict the behavior of the UHPFRC arch. Results indicated that a wall thickness of 50 mm with stirrups effectively restrained instability failure of the thin-walled compression columns. The cracking load and the ultimate load of the UHPFRC arch increased by 60% and 34%, respectively, when comparing with the NC arch. It showed the UHPFRC arch had higher load capacity and outstanding durability. The failure mode of the UHPFRC arch was similar to that of the NC arch, which belonging to the destruction of multihinges. However, the appearance of the plastic hinges was delayed, and a better elastic-plastic performance was obtained when using UHPFRC. The analytical formula for calculating the ultimate load of the UHPFRC arch was derived with high precision by using the limit equilibrium method. The results of the FEM showed good agreement with test results, and they were able to predict the behavior of the UHPFRC arches. © 2019 Jun Yang et al.",,,,,,,"National Natural Science Foundation of China, NSFC: 51808081; National Key Research and Development Program of China, NKRDPC: 2017YFC0806007; National Science Fund for Distinguished Young Scholars: 51425801","+e authors acknowledge the support of the National Key Research and Development Program of China (2017YFC0806007), the National Science Fund for Distinguished Young Scholars (51425801), and the National Natural Science Foundation of China (51808081).","The authors acknowledge the support of the National Key Research and Development Program of China (2017YFC0806007), the National Science Fund for Distinguished Young Scholars (51425801), and the National Natural Science Foundation of China (51808081).",,,,,,,,,"Zhou, M., Lu, W., Song, J., Lee, G.C., Application of ultrahigh performance concrete in bridge engineering (2018) Construction and Building Materials, 186, pp. 1256-1267;

In a high-energy impact scenario, such protective structures can absorb a large amount of energy through plastic deformation. Many previous studies are based on empirical static analysis which ignores important dynamic effects involved in an impact event. Finite-element simulation serves as an alternative approach which is commonly used for dynamic analysis of vessel collisions. However, finite-element simulation is expensive regarding both calculation time and computing resources. To conquer these problems, a simplified impact model considering soil-pile interactions and geometric non-linearity is developed in this paper based on the coupled multi-degree-of-freedom model previously proposed by the authors. The computational cost can be remarkably reduced by the simplified models. The influences of pile cross-section diameter, pipe thickness, pile length, free span of pile and soil properties on the energy dissipation capacity of pile-supported protective structures are investigated in this paper using the simplified models. © 2018","Coupled multi-degree-of-freedom model; Geometric non-linearity; Protective structures; Simplified impact model; Soil-pile interactions","Degrees of freedom (mechanics); Energy dissipation; Finite element method; Gears; Soils; Steel pipe; Ultrasonic devices; Geometric non-linearity; Impact model; Multi degree-of-freedom; Protective structures; Soil-pile interactions; Piles; barge; collision; finite element method; nonlinearity; numerical model; pile; soil-structure interaction",,,,,"China Scholarship Council, CSC","The authors wish to thank the China Scholarship Council for providing the scholarship for the first author of this paper.",,,,,,,,,,"Saul, R., Humpf, K., Patsch, A., The Rosario-Victoria cable-stayed bridge across the river Paran in Argentina and its ship impact protection system (2001) Proceedings of the first international conference on steel and composite structures, pusan, korea, pp. 1011-1018; Morgenthal, G., Saul, R., Die Geh- und Radwegbruecke Kehl - Strasbourg (2005) Stahlbau, 74 (2), pp. 121-125. , (in German); Knott, M., Pier protection system for the sunshine skyway bridge replacement (1986) Proceedings at 3rd annual international bridge, pittsburghn, PA, pp. 56-61; Rao, S.N., Ramakrishna, V.G.S.T., Raju, G.B., Behavior of pile-supported dolphins in marine clay under lateral loading (1996) Journal of Geotechnical Engineering, ASCE, 122 (8), pp. 607-612; Patsch, A., Gerbaudo, C.F., Prato, C.A., Analysis and testing of piles for ship impact defenses (2001) Journal of Bridge Engineering, ASCE, 7 (4), pp. 236-244; Zhu, B., Chen, Y.M., Zhang, Z.H., Impact model tests and simplified analysis for flexible pile-supported protective structures withstanding vessel collisions (2012) Journal of Waterway, Port, Coastal, and Ocean Engineering, ASCE, 138 (2), pp. 86-96; Sun, Z., Wang, J.J., Numerical simulations of pile supported protective system subjected to ship impact (2006) Trans Tianjin Univ, 12 (z1), pp. 243-247; Fan, W., Yuan, W.C., Numerical simulation and analytical modeling of pile-supported structures subjected to ship collisions including soilstructure interaction (2014) Ocean Eng, 91, pp. 11-27; Consolazio, G.R., Cowan, D.R., Numerically efficient dynamic analysis of barge collisions with bridge piers (2005) Journal of Structural Engineering, ASCE, 131 (8), pp. 1256-1266; Yuan, P., Harik, I.E., One-dimensional model for multi-barge flotillas impacting bridge piers (2008) Comput Aided Civ Infrastruct Eng, 23 (6), pp. 437-447; Yuan, P., Modeling, simulation, and analysis of multi-barge flotillas impacting bridge piers (2005), Ph.D. thesis Department of Civil Engineering, University of Kentucky Lexington, Kentucky; Sha, Y.Y., Hao, H., A simplified approach for predicting bridge pier responses subjected to barge impact loading (2014) Adv Struct Eng, 17 (1), pp. 287-296; Wang, W., Morgenthal, G., Development and assessment of efficient models for barge impact processes based on nonlinear dynamic finite element analyses (2018) Eng Struct, 175, pp. 617-627; Wang, W., Morgenthal, G., Dynamic analyses of square RC pier column subjected to barge impact using efficient models (2017) Eng Struct, 151, pp. 20-32; Wang, W., Morgenthal, G., Novel crashworthy device for pier protection from barge impact (2018) Adv Civ Eng, 2018, p. 9385643; Wang, W., Morgenthal, G., Reliability analyses of RC bridge piers subjected to barge impact using efficient models (2018) Eng Struct, 166, pp. 485-495; Cao, C.H., Simplified static and dynamic analysis for barge-bridge collision (2010), Master's thesis Department of Bridge Engineering, Tongji University Shanghai, China (in Chinese); Sha, Y.Y., Hao, H., Nonlinear finite element analysis of barge collision with a single bridge pier (2012) Eng Struct, 41, pp. 63-76; American Petroleum Institute, Washington, D.C., recommended practice for planning, designing and constructing fixed offshore platforms-working stress design (2002); Consolazio, G.R., Cook, R.A., Biggs, A.E., Cowan, D.R., Barge impact testing of the st.

Such an effect becomes more severe in the case of the aged structures, specifically masonry arch bridges. This research initially provides a probabilistic estimation for the impact factor based on the ratio of the dynamic to static loads by using Weigh-In-Motion data. Then, the research is followed by proposing a new finite elements approach for a more precise estimation of the structure response pattern and a more rigorous evaluation of the masonry arch bridges. It uses optimization techniques for updating the model and results in the probabilistic estimation of the impact factor by using field measurements. Through these two methods and by using data from continuous monitoring of an 80-year-old masonry arch bridge with a length of 100 m and a span of 66 m, the impact factor is surveyed. The outputs prove to be 50% more accurate compared with the already established methods. The rate of variations of the impact factor within the first proposed method is 1.6 times more compared with the second approach. This emphasizes the uncertainties in the available approaches and the probabilistic nature of the impact factor. Therefore, the assumption of the absolute certainty for the impact factor becomes questionable. This survey reveals that for the best cases, the available certainty-based methods can only cover 17% of the probabilistic domain of the impact factor. © 2020 John Wiley & Sons, Ltd.","dynamic amplification factor;

But the relatively short available space between rivets requires the use of adhesively-bonded CFRP laminates with short bond lengths, which needs to be deeply studied as most previous research works have focused on large bond lengths. To study the bond behaviour between CFRP laminates and steel plates in such strengthened structures, a series of tests has been carried out in double-strap joints under tensile loading, evaluating the influence of CFRP stiffness and adhesive ductility on the strength and failure mode of short bond length adhesive joints. Based on the experimental results of the present work, together with a large database collected from literature, a fracture-mechanics model based on interfacial fracture energy in shear GII is calibrated, and a simple expression is developed to be used in design for the strength prediction of such adhesive joints. Finally, double-strap joint specimens are simulated using cohesive zone models (CZM) for the adhesive layers, and the results are compared to the analytical model and experimental tests. © 2020 Elsevier Ltd","Carbon fibre reinforced polymer; CFRP-steel adhesive joints; Cohesive zone models; Finite element analysis; Fracture mechanics; Mechanical testing","Adhesive joints; Bond length; Carbon fibers; Ductility; Elasticity; Fracture mechanics; Laminates; Rivets; Steel corrosion; Steel fibers; Stiffness; Structural design; Adhesively bonded; Cohesive zone model; Double strap joints; Experimental test; Fracture mechanics model; Interfacial Fracture energy; Simple expression; Strength prediction; Adhesives",,,,,"Horizon 2020 Framework Programme, H2020: 730841; European Commission, EC","The research leading to these results has received partial funding from the European Union's Horizon 2020 Programme in the framework of the research project IN2TRACK under grant agreement n° 730841.",,,,,,,,,,"Hosseini, A., Ghafoori, E., Al-Mahaidi, R., Zhao, X.L., Motavalli, M., Strengthening of a 19th-century roadway metallic bridge using nonprestressed bonded and prestressed unbonded CFRP plates (2019) Constr.

The novel current profile is initially developed from the harmonic current injection method and is then modified into a unipolar waveform to allow the application of an asymmetric bridge inverter. It is found that, neglecting the magnetic saturation, the optimal current profile for the maximum torque per ampere operation in an SRM is close to a pulse with high-order harmonics. However, an optimized current with relatively low-order harmonics can provide better performance in the practical situation. Based on the analytical and the finite element results, the proposed method is proved to be able to enhance the torque density by 20% at the light load condition and by 15% at the rated condition compared with the conventional SRM excitation. Also, the large torque ripple and core loss in SRMs are suppressed and the efficiency is improved. More importantly, unlike many other current profiling techniques, the proposed current profile has fixed parameters and is easily adaptable to different machine specifications. The effectiveness of the proposed method is verified by both the finite-element analyses and the experiments. © 1982-2012 IEEE.","Current profile; harmonic current injection method; reluctance machine; torque density","Harmonic analysis; Torque; Harmonic current injection; High order harmonics; Low order harmonics; Low-speed applications; Maximum Torque per Ampere; Optimal current profiles; Switched Reluctance Machine; Torque density enhancements; Finite element method",,,,,,,,,,,,,,,,"Lawrenson, P.J., Stephenson, J.M., Blenkinsop, P.T., Corda, J., Fulton, N.N., Variable-speed switched reluctance motors (1980) Inst.

These forces lead to contact loss and thus an increase in the derailment probability. In this paper, experimental and analytical data are employed to study the impact force as the wheel crosses over a broken rail. In the experimental tests, the wheel-rail impact forces were measured using a Wheatstone bridge circuit. Prior to the field tests, the calibration factor of the Wheatstone bridge was determined by lab experiments. A three-dimensional finite element model (3D FEM) of the wheel and rail was developed and verified using the experimental test results. Using the numerical model, the effects of the distance between the breakage location and the adjacent sleeper, temporary repair of broken rails, and sleeper spacing on the wheel-rail impact forces were studied. The developed numerical model provided acceptable estimations of wheel-rail impact loads, as the difference of estimated and measured impact load is limited to 17%. According to the results of the numerical model, if the rail breakage is positioned between the two adjacent sleepers, impact forces are almost half of that of when the rail breakage occurs close to a sleeper. Moreover, the wheel-rail contact is not lost for any crossing speed of the vehicle. Also, by increasing the sleeper spacing from 60 cm to 70 cm, the impact load increases by an average of 20%, while reducing the sleeper spacing from 60 cm to 50 cm can decrease the impact loads by an average of 13%. © 2020","Contact-impact forces; Dynamic analysis; Finite element; Rail breakage; Wheel-rail interaction","3D modeling; Bridge circuits; Numerical models; Calibration factors; Experimental test; Numerical experimental; Three dimensional finite element model; Wheatstone bridge circuits; Wheatstone bridges; Wheel-rail contacts; Wheel-rail impacts; Vehicle wheels",,,,,,,,,,,,,,,,"Mandal, N.K., Finite element analysis of the mechanical behavior of insulated rail joints due to impact loadings (2016) Proc.

Thus, there have been number of studies concentrated on the behavior of in-plane beam-column sub-assemblages under a single column removal scenario. However, the effect of possible multicolumn loss scenarios due to severe vehicular impact or terrorist attacks has been neglected in the previous CAA calculation models. This paper develops analytical models to estimate CAA capacity of 3D beam-column sub-assemblages under failure of one or two adjacent interior columns. Due to shortage of relevant data, the proposed formulas are validated through comparisons with the numerical results of a full-scale sub-assemblage. Evaluating the response of sub-assemblages extracted from sample buildings with various frame span lengths, it is shown that the failure of two adjacent interior columns along shorter spans of the floor is more likely to reduce CAA capacity than loss along longer spans. The contributions of the bridging beams over removed columns to arch action capacity are also compared. © 2020 Elsevier Ltd","Failure mechanism; Finite element analysis; Stress analysis; Stress distribution; Structural failures","Analytical models; Arch bridges; Arches; Reinforced concrete; Calculation models; Column removal; Load bearing mechanism; Numerical results; Progressive collapse; Reinforced concrete frames; Terrorist attacks; Vehicular impacts; Failure (mechanical)",,,,,,,,,,,,,,,,"(2013), Abaqus Analysis User's Manual 6.13.

Three sizes of samples for carbon fiber needled felt reinforced composites were designed and prepared. The tensile properties were investigated by experiments and theoretical methods, and the influences of sample size on tensile modulus were discussed. The results showed that, the longitudinal tensile moduli of carbon fiber needled felt reinforced composites decreased with the increase of sample size. Compared with the rule of mixtures and the inclusion theory, the longitudinal tensile moduli obtained by finite element method were closer to the experimental values. In addition, the transverse tensile moduli obtained by finite element method were greater than that obtained by the rule of mixtures and the inclusion theory. That was due to the orientation of some fibers had a proportion along the thickness. It was concluded that, these three-dimensional finite element models can be used to investigate the elastic properties of carbon fiber needled felt reinforced composites with different sizes. © The Author(s) 2019.","finite element method; modeling; Short fiber-reinforced composites; tensile properties","Carbon fibers; Composite bridges; Elastic moduli; Felt; Felts; Fiber reinforced plastics; Mixtures; Models; Reinforcement; Tensile properties; Elastic properties; Experimental values; Longitudinal tensile; Reinforced composites; Short-fiber-reinforced composites; Theoretical methods; Three dimensional finite element model; Transverse tensile; Finite element method; Carbon Fibers; Mixtures; Models; Reinforcement; Tensile Properties",,,,,,,,,,,,,,,,"Li, Y., Chen, Z., Su, L., Stochastic reconstruction and microstructure modeling of SMC chopped fiber composites (2018) Compos Struct, 200, pp. 153-164; Chen, X., Chen, L., Zhang, C., Three-dimensional needle-punching for composites—a review (2016) Compos Part A, 85, pp. 12-30; Neisiany, R.E., Khorasani, S.N., Naeimirad, M., Improving mechanical properties of carbon/epoxy composite by incorporating functionalized electrospun polyacrylonitrile nanofibers (2017) Macromol Mater Eng, p. 302; Salimian, S., Malfait, W.J., Zadhoush, A., Fabrication and evaluation of silica aerogel-epoxy nanocomposites: fracture and toughening mechanisms (2018) Theoret Appl Fract Mech, 97, pp. 156-164; Zadhoush A, Reyhani R and Naeimirad M.

This paper presents a detailed experimental investigation on CHS beams made of 6082-T6 aluminum alloys. The effects of length and section slenderness on the ultimate strength and buckling behaviour were investigated. Seventeen extruded CHS specimens were subjected to four-point bending tests, with the diameter-to-thickness ratio (D/t) ranging from 16.4 to 29.1. The failure modes observed included overall buckling and the coupling of local and overall buckling. The initial geometric imperfections were measured prior to the bending tests. Subsequently, fine finite-element (FE) models were developed using the nonlinear analysis program ABAQUS and validated against the experimental results. An extensive parametric study involving 600 numerical results was performed to evaluate the effects of D/t, the section dimensions, and the slenderness ratio on the mechanical responses and bending strength of the CHS beams. The test results, together with the obtained FE analysis results, were utilised to assess the accuracy of the bending-strength provisions in the current design codes GB 50429 (China), Eurocode 9 (Europe), and AA-2015 (America), as well as optional design approaches, i.e. the direct strength method (DSM) and continuous strength method (CSM). The results indicated that all five design provisions provided conservative predictions of the ultimate moment capacities; the predicted results of DSM and CSM were more accurate than the three design specifications. The reliability levels of the bending-strength provisions were confirmed and compared using statistical parameters from the corresponding specifications. © 2020 Institution of Structural Engineers","6082-T6 aluminum alloy; Bending strength; Circle hollow section; Continuous strength method; Direct strength method; Finite element analysis; Reliability analysis",,,,,,"National Natural Science Foundation of China, NSFC: 51978208; Harbin Institute of Technology, HIT","This research program is financially supported by National Natural Science Foundation of China (Grant no. 51978208).

Engineering practice in the scaffolding industry, however, does not have a rational structural reliability basis as that used for buildings and bridges. The implementation of design clauses for scaffold systems in the current standards partially relies on judgement suffering from the lack of data. With this regard, a reliability-based limit state design approach is developed in this study, making full use of the advanced finite element (FE) method and the recently accumulated statistical data of scaffolding resistance and construction loads. A stochastic finite element method is used to obtain the probabilistic characteristics of the ultimate load-carrying capacities of typical scaffolding frames, accounting for the uncertainties associated with structural geometry, material and stiffness properties. The latest construction load survey data is utilized. System reliability assessment is then performed to develop new design criteria which are consistent with generally accepted structural reliability targets. © 2020 Elsevier Ltd","Construction loads; Nonlinear frame analysis; Reliability-based design; Steel scaffold; Structural reliability; System-based design","Bridges; Finite element method; Load limits; Scaffolds; Stochastic systems; Catastrophic consequences; Engineering practices; Probabilistic characteristics; Scaffolding systems; Stiffness properties; Stochastic finite element method; Structural reliability; Ultimate load-carrying capacity; Reliability; carrying capacity; construction method; design method; limit analysis; loading; reliability analysis; stiffness",,,,,"Australian Research Council, ARC: DP190103737","This research has been supported by Australian Research Council under Discovery Project Grant DP190103737 .

A literature case regarding a closed box section of a suspended bridge was selected since it is of practical relevance. An OpenFOAM implementation of a Spalart–Allmaras local correlation based transition model for Reynolds Averaged Navier–Stokes (RANS) equations was used as flow model. Locally-formulated RANS transition models were coupled with the Spalart–Allmaras (SA) model to reduce the computational cost with respect to the SST k − ω model. This model, named γ−Rθ,t˜-SA, was successfully applied on airfoil sections and results are given by literature. In this paper, we present a set of computations of the flow field around a bluff body in order to stress the need to take into account transition effects in these kind of applications. The measure of the proposed model reliability was attested comparing experimental pressure coefficients and aerodynamic forces on the bridge section; besides, the effects of the model predictions on the critical flutter velocity, estimated by FEM and 2DOF Scanlan model of a pedestrian bridge structure, was examined as case of study. © 2020 Elsevier Ltd","Bridge aerodynamics; CFD; Fluid mechanics; Spalart–Allmaras; Wind tunnel","Aerodynamics; Fluid mechanics; Footbridges; Navier Stokes equations; Wind tunnels; Aerodynamic forces; Bluff body aerodynamics; Bridge aerodynamics; Computational costs; Computational fluid dynamics simulations; Computational studies; Laminar to turbulent transitions; Pressure coefficients; Computational fluid dynamics",,,,,,,,,,,,,,,,"Bai, Y., Sun, D., Lin, J., Three dimensional numerical simulations of long-span bridge aerodynamics, using block-iterative coupling and DES (2010) Comput Fluids, 39, pp. 1549-1561; Das, S.N., Shiraishi, S., Das, S.K., Mathematical modeling of sway, roll and yaw motions: order-wise analysis to determine coupled characteristics and numerical simulation for restoring moment's sensitivity analysis (2010) Acta Mech, 213 (3-4), pp. 305-322; Parolini, N., Quarteroni, A., Mathematical models and numerical simulations for the America's cup (2005) Comput Meth Appl Mech Eng, 194 (9-11), pp. 1001-1026; Ankush Rainaa, G.A., Haqa, H.M.I.U., Numerical investigation of flow around a 3D bluff body using deflector plate (2017) Int J Mech Sci, 131-132, pp. 701-711; Jung, S.Y., Kim, J.J., Park, H.W., Lee, J.S., Comparison of flow structures behind rigid and flexible finite cylinders (2018) Int J Mech Sci, 142-143, pp. 480-490; Martins, F.A.C., Avilla, J.P.J., Effects of the Reynolds number and structural damping on vortex-induced vibrations of elastically-mounted rigid cylinder (2019) Int J Mech Sci, 156, pp. 235-249; Menter, F.R., Langtry, R.B., Volker, S., Transition modelling for general purpose CFD codes (2006) Flow Turbul Combust, 77, pp. 277-303; Menter, F.R., Langtry, R., Likki, S., Suzen, Y., Huang, P., Volker, S., A correlation based transition model using local variables – part 1: model formulation (2006) J Turbomach, 128, pp. 413-422; Walters, D.K., Cokljat, D., A three-equation eddy-viscosity model Reynolds-Averaged Navier-Stokes simulations of transitional flow (2008) J Fluids Eng Trans ASME, 130 (12), pp. 1214011-12140114; Cid Montoya, M., Nieto, F., Álvarez, A.J., Hernández, S., Á., J.J., Sánchez, R., Numerical simulations of the aerodynamic response of circular segments with different corner angles by means of 2D URANS.

This paper investigates and compares reliability assessments of stay cables by using identified cable tension forces and monitored bridge loads. One-year monitoring data from a cable-stayed bridge was used to characterize the probability distributions of cable forces and pertinent bridges loads including temperature of the cable, wind load, and vehicle load. The results show that, for the bridge under study, the cable temperature, the wind load, and the vehicle weight obey the Beta distribution, whereas the axle weight obeys the lognormal distribution, indicating deviations from the design codes. Subsequently, two performance functions are proposed to compute the cable reliability index, where one directly uses the monitored cable forces and the other is based on the monitored loads and the finite element method simulation of the bridge. The computed index based on the monitored cable forces and the performance function I is larger than that based on the monitored loads and the performance function II. The reasonings attributed to the differences and the implication of the present findings in structural design and optimization are discussed. © 2020 American Society of Civil Engineers.","Performance function; Probability distributions; Reliability analysis; Stay cables; Structural health monitoring; Structural optimization","Aerodynamic loads; Cable stayed bridges; Monitoring; Probability distributions; Reliability analysis; Robustness (control systems); Structural design; Structural optimization; Wind stress; Beta distributions; Cable reliability; Cable temperatures; Design and optimization; Finite element method simulation; Log-normal distribution; Performance functions; Reliability assessments; Bridge cables",,,,,"51478347; State Key Laboratory for Disaster Reduction in Civil Engineering; National Basic Research Program of China (973 Program): 2017YFC1500605","The research described in this paper was supported by the National Nature Science Foundation of China (Grant No. 51478347), the National Key Research and Development Program of China (Grant No. 2017YFC1500605), and the State key Laboratory of Disaster Reduction in Civil Engineering (Grant No. SLDRCE15-A-02), which is greatly appreciated.",,,,,,,,,,"(2017) AASHTO LRFD Bridge Design Specifications, , AASHTO. 8th ed.

This study investigates the mechanical behavior of a diaphragm-blister integrated anchorage system (DBIAS) used in UHPC box-girder bridges through the full-scale model test. Parametric analyses were also conducted using test-validated finite-element models. Experimental results show that no visible cracks have emerged when the applied load reaches 4,700 kN, which is 1.36 times the design value. Although the strain in some local areas has entered into the tensile strain-hardening domain of UHPC under the prestressing force, the whole structure still works well. The contribution of strain-hardening behavior of UHPC to the loading capacity of anchorage blister is 8.7%, based on nonlinear finite-element analysis. Therefore, the tensile strain capacity of UHPC may be taken into consideration in the design so as to fully make use of the material strength. Compared with the conventional independent blister anchorage system, the local effects on the anchorage zone are significantly reduced by setting anchorage diaphragms and transverse ribs in a DBIAS. The increase in the width and longitudinal spacing of adjacent diaphragms shows effectiveness in relieving the stress concentration in the anchorage zone. However, local effects will not be continuously reduced when the width of the diaphragm is more than six times that of the anchorage blister or the spacing between the diaphragm and the transverse rib exceeds a certain distance (2 m in the present study case). © 2020 American Society of Civil Engineers.","Anchorage zone; Full-scale model test; Parametric analysis; Prestressed concrete bridges; Thin-walled box girder; Ultra-high performance concrete","Anchorages (foundations); Beams and girders; Box girder bridges; Finite element method; High performance concrete; Prestressed concrete; Prestressing; Steel bridges; Strain hardening; Tensile strain; Full-scale model tests; Non-linear finite-element analysis; Numerical investigations; Parametric -analysis; Strain hardening behavior; Structural behaviors; Tensile strain capacities; Ultra high performance concretes (UHPC); Anchorage zones",,,,,,,,,,,,,,,,"Aaleti, S., Petersen, B., Sritharan, S., (2013) Design Guide for Precast UHPC Waffle Deck Panel System, including Connections, , Publication No. FHWA-HIF-13-032.

An algorithm of the PVCE method considering serial crack extensions and quasi-static analysis is proposed, and the modified PVCE method is further introduced to reduce the computational error. As validation and application examples, the developed PVCE method is applied to compute the energy release rates of single edge-notched tension (SENT), double cantilever beam (DCB), and end loaded split (ELS) tests, and the results are compared with the existing analytical solutions and numerical finite element analysis. The new PVCE method builds a natural “bridge” for peridynamic fracture analysis between the peridynamics and classical fracture mechanics, and it is capable of accurately and effectively computing the energy release rates for both mode I and mode II fracture cases as well as predicting the critical load and displacement in fracture analysis. © 2020 Elsevier B.V.","Energy release rate; Fracture analysis; Peridynamics; Virtual crack extension","Cantilever beams; Energy release rate; Fracture mechanics; Joints (structural components); Numerical methods; Application examples; Double cantilever beam; Fracture analysis; Numerical implementation; Peridynamics; Quasi static analysis; Single edge notched tensions; Virtual crack extension; Cracks",,,,,"National Natural Science Foundation of China, NSFC: 11972224, 51678360, 51679136","The partial financial support from the National Natural Science Foundation of China (NSFC Grant Nos. 11972224 , 51679136 and 51678360 ) to this study is acknowledged.",,,,,,,,,,"Watwood, V.B., The finite element method for prediction of crack behavior (1969) Nucl.

Recent design standards specify that intermediate diaphragms, which prevent deformation of the box section, need to be installed to control these distortional warping normal stresses. In addition, the maximum ratio requirements between distortional warping normal stress and bending normal stress should not exceed 5 and 10%, respectively. However, the design standards do not provide specific formulae for use in determining the appropriate intermediate diaphragm spacing; therefore, an accurate structural analysis is required from the design stage and the iterative structural analysis time-consuming. In this study, to simplify the structural analysis steps required in the design phase, a parametric study was conducted using 3D finite element analysis (FEA) to estimate the intermediate diaphragm spacing required for composite simple span single-cell box girder bridges. In the parametric study, the box girder bridges were modeled using actual bridge data relating to the cross-sectional aspect ratio, span length, and flange thickness. The FEA results show that the coupling effects of the cross-sectional aspect ratio, the ratio of the distortional warping constant to the moment of inertia, span length, and eccentricity, have a significant effect on the diaphragm spacing and normal stress ratio. Based on these FEA results, efficient intermediate diaphragm spacing was determined in consideration of the cross-sectional aspect ratio, span length, and flange thickness. © 2019","Distortion; Intermediate diaphragm; Single span; Spacing; Steel box girder","Aspect ratio; Composite beams and girders; Distortion (waves); Flanges; Steel bridges; Steel structures; Structural analysis; 3D-finite element analysis; Distortional warping; Intermediate diaphragm; Longitudinal direction; Moment of inertia; Single span; Spacing; Steel box girders; Box girder bridges",,,,,"Ministry of Education, MOE: 2019R1I1A1A01059684; National Research Foundation of Korea, NRF","This research was supported by the Basic Science Research Program through the National Research Foundation of Korea ( NRF ), funded by the Ministry of Education (Grant No. 2019R1I1A1A01059684 ).",,,,,,,,,,"American Association of State Highway and Transportation Officials, AASHTO LRFD Bridge Design Specifications (2017), 8th Ed American Association of State Highway and Transportation Officials; Steel Structure Study Committee of Hanshin Expressway Public Corporation, Guidelines for the Design of Horizontally Curved Girder Bridges (1988), Hanshin Expressway Public Coporation; Dabrowski, R., Curved Thin-Walled Girders.

First, two existing analytical methods for calculating the stress on rotor iron bridges were investigated using a flat-type IPMSM model. The calculations of centroid radii required by these methods were simplified by taking advantage of the symmetry. Then, an accurate function of the stress concentration factor (SCF) was developed to calculate the maximum mechanical stress (MMS) on the iron bridge from its reference stress. The trends of SCF and MMS changing with geometrical parameters were obtained during the statistical analysis of SCF. Using the proposed analytical method, MMS on the bilateral iron bridges of both flat- and V-type IPMSMs can be calculated accurately. Finite element analysis (FEA) shows that the proposed method has improved accuracy and generality in calculations of the MMS. The reliability of the FEA model and the proposed analytical method were further investigated in a plastic deformation experiment. Based on the experimental results, the limits of the stress models, selection of the failure criteria, and safety factor were discussed for high-speed IPMSM design. © 1972-2012 IEEE.","Finite element analysis (FEA); high-speed motor; interior permanent-magnet synchronous machine (IPMSM); maximum stress; mechanical stress; permanent magnet machine; stress concentration factor (SCF)","Electric current regulators; Finite element method; Geometry; Iron; Robustness (control systems); Safety factor; Stress concentration; Synchronous machinery; High speed motors; Interior permanent magnet synchronous machine; Maximum stress; Mechanical stress; Permanent-magnet machine; Stress concentration factors; Permanent magnets",,,,,"Australian Research Council, ARC: 2019-EMC-0612, DP170102288","Manuscript received July 12, 2019; revised September 23, 2019 and November 13, 2019; accepted November 14, 2019.

This technical note presents a protocol for determination of the model parameters of the Hardening Soil model from a set of triaxial compression tests. The technical note also describes details about how to determine the Mohr-Coulomb strength parameters c and ϕ for well-compacted fills (with and without cohesion), of which the failure envelopes are typically curved. The motivation for preparing this technical note came from a study on analysis of field-scale soil–geosynthetic composites in which the soil model and model parameters deduced from triaxial tests were able to predict with very good accuracy “all” measured results of five field-scale soil–geosynthetic composites under increasing applied vertical loads up to 1000 kPa (approximately five times the load level commonly used in design of reinforced soil bridge abutments). The model parameters were determined by a well-defined protocol. The protocol should be of value to researchers and engineers who use the soil model for sophisticated finite element analysis and design of earth structures. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.","Curved failure envelope; Finite element analysis; Hardening Soil model; Model parameters; Mohr-Coulomb strength parameters; Plaxis",,,,,,"Federal Highway Administration, FHWA",,,,,,,,,,,"Gaur, A., Sahay, A., Comparison of different soil models for excavation using retaining walls (2017) SSRG International Journal of Civil Engineering, 4 (3), pp. 43-48; Morrison, K.F., Harrison, F.E., Collin, J.G., Dodds, A., Arndt, B., (2006) ""Shored mechanically stabilized earth (SMSE) wall systems design guidelines.""

In order to address this issue, the multiscale finite element (FE) modeling was developed in this work to analyze the burrs formation mechanism. The proposed model combined the microscopic fiber and matrix phases with the macroscopic equivalent homogeneous material (EHM). Meanwhile, 3D Hashin-type damage initiation criteria were proposed to characterize the differences between the tensile and compressive strength of the EHM and fiber and their anisotropy feature. The cutting of the fiber and matrix phases under all cutting angles were divided into two simulation processes to improve the computational efficiency. With the help of this model, the thrust force was accurately predicted where the distribution of burrs was successfully simulated compared with the experimental measurements. In addition, the evolution process from the failure of the fiber and matrix phases towards formation of the burrs was clarified. It could be seen that in the drilling of the CFRPs at the hole exit, the matrix was removed while the fibers deformed out-of-plane under the push of the drill firstly rather than got removed and then bent with the rotation of the drill. Specifically, the fibers under acute cutting angles bent outward the hole radially, which made them more difficult to be removed and hence resulted in the burrs eventually. The revealed formation mechanisms would be the crucial contribution and guidance for helping to suppress the burrs. © 2020, Springer-Verlag London Ltd., part of Springer Nature.","Burrs; CFRPs; Cutting angle;

This study is focussed on understanding the mechanics of chip formation in orthogonal cutting of unidirectional (UD) carbon-fibre-reinforced polymer (CFRP) laminates through development of FE models. Machining responses of UD CRFP laminates with fibre orientation of 45°(measured with respect to the cutting direction) are assessed. Modelling of material removal in the form of fragmented chips is considered. Damage initiation is determined using the Hashin stress criterion for the fibre component, while matrix failure predicted using Puck criteria. Subsequent damage evolution events are modelled using a strain-based softening approach to degrade relevant material properties linearly. Primary numerical results compared with experimental data revealed that developed FE models are able to predict global machining responses (i.e. cutting forces) and characterise various discrete damage modes associated with machining response of quasi-brittle CFRP laminates successfully. The models also provide a valuable insight into variation in chip morphology. © 2nd CIRP Conference on Composite Material Parts Manufacturing,CIRP-CCMPM 2019.

In this study, a complete bridge analysis model is proposed to investigate the dynamic responses of offshore bridges in the Bohai Sea subjected to stochastic ice loads by floating sea ice. Based on a real stochastic ice load spectrum, a simulation methodology to generate the stochastic ice load process is proposed. The soil resistance is modelled utilising the American Petroleum Institute-based cyclic p-y, t-z, and Q-z springs. A dynamic analysis is conducted in the time domain utilising the finite element method and considering stochastic ice loads. The influences of undrained soil strength and water depth on the dynamic behaviours of the bridge are systematically investigated. The results show that the dynamic responses of bridges in deep water are much larger than those in shallow water, and the soil–structure interaction (SSI) can substantially affect the structural vibrations. The result from the method can also be used to identify the most critical condition for bridge design under ice loads. © 2019 Elsevier Ltd","Bridges; Dynamic analyses; SSI; Stochastic ice loads","Bridges; Dynamic analysis; Dynamic response; Offshore oil well production; Offshore structures; Piles; Sea ice; Soil structure interactions; Soils; Stochastic models; Stochastic systems; Structural dynamics; American Petroleum Institute; Bridge analysis; Critical condition; Dynamic behaviours; Ice loads; Simulation methodology; Structural vibrations; Supported bridges; Time domain analysis; bridge; dynamic response; ice mechanics; loading; numerical model; pile; soil-structure interaction; stochasticity; water depth; Bohai Sea; Pacific Ocean; Yellow Sea",,,,,"National Natural Science Foundation of China, NSFC: 51778108","This work was sponsored by the National Natural Science Foundation of China ( 51778108 ).

The problem is complicated by the multimode and dispersive behaviour of the guided waves. This paper describes a unified Global-Local (GL) approach that is computationally efficient in cases that can be very complex in terms of geometry and/or material properties. One example of this is a composite built-up structure. The proposed GL procedure discretizes the “local” region with the scattering discontinuity by regular finite elements, and utilizes the efficient Semi-Analytical Finite Element solutions in the “global” region away from the scatterer. The GL formulation that is presented includes the dispersive unforced solutions for each applicable mode, the mode tracking, the scattered spectra (reflection and transmission), and the energy balance calculations. The algorithm is applied to the case of a composite skin-to-stringer assembly used in modern aircraft construction. Various representative defects in this assembly are modelled, and transmission spectra are calculated for both axial or flexural guided wave modes used in excitation. The resulting scattered spectra (which are the broadband transfer functions of the structure) can be useful to either select suitable wave mode-frequency combinations or to identify specific defects in guided-wave NDT or SHM tests of these components. © 2019 Elsevier Ltd","Composite structures; Global-Local method; Guided elastic waves; Non-destructive testing; Scattering; Semi-analytical finite element method; Structural health monitoring","Bridge decks; Composite structures; Defects; Dispersion (waves); Elastic waves; Guided electromagnetic wave propagation; Nondestructive examination; Plates (structural components); Scattering; Structural health monitoring; Structure (composition); Computationally efficient; Defect characterization; Energy balance calculations; Global-local methods; Non destructive testing; Reflection and transmission; Semi-analytical finite element; Semi-analytical finite element methods; Ultrasonic testing",,,,,"Federal Aviation Administration, FAA: E0584038","Part of this work was funded by the Federal Aviation Administration Joint Center of Excellence for Advanced Materials (FAA Cooperative Agreement 12-C-AM-UCSD ).

The current calculation method of Part 1.5 of Eurocode 3 is based on the concept that the behaviour can be superposed from plate-like and column-like behaviours. Recent results indicate uncertainties in the application of the current method, e.g., if applied to plates with closed stiffeners. It is also known that the critical buckling stress is dependent on how it is calculated: by using a shell finite element model or by using the equations from Annex A of the relevant code part. The two calculation methods can lead to significant differences in the critical stress, which then mirrored in the resistance. Some results indicate that shell finite element calculation of the critical stresses can lead to resistance overestimation, especially when closed stiffeners are used. However, the reasons of the differences between the numerically and analytically calculated critical stresses are not yet fully clarified. Therefore, in the current paper the elastic critical buckling stress and buckling resistance of longitudinally stiffened plates are discussed. The paper presents the results of an extensive numerical research program focusing first on the critical buckling stress, then on the buckling resistance of plates with closed stiffeners. Reasons of the experienced differences between the critical stresses are explained in full detail. Moreover, possible enhancement of the resistance prediction is indicated. © 2019 Elsevier Ltd","Constrained finite element method; Longitudinal stiffeners; Plate-like buckling; Stiffened plates; Trapezoidal stiffeners","Bridges; Codes (standards); Finite element method; Orthotropic plates; Buckling resistance; Critical buckling stress; Critical stress; Longitudinal stiffener; Numerical research; Shell finite elements; Stiffened plate; Trapezoidal stiffeners; Buckling",,,,,"Magyar Tudományos Akadémia, MTA; Emberi Eroforrások Minisztériuma, EMMI; Nemzeti Kutatási Fejlesztési és Innovációs Hivatal, NKFIH","The presented work was conducted with the financial support of the K119440 project of the Hungarian National Research, Development and Innovation Office.

For each dome, the structural responses, including the joint displacement and member strain of the remaining components, were recorded after four key members were abruptly removed in succession. The effects of the rise-to-span ratio on the progressive collapse resistance of the K6 single-layer latticed domes were examined after constructing and validating finite element (FE) models. The experiments and FE analysis yielded the following results: 1) K6-6 and K6-8 domes have identical collapse modes; the joint loads were transferred via surrounding localised arch action, and the collapse of the arch following member failure led to the progressive collapse of the latticed domes. 2) Compression mechanisms served to inhibit progressive collapse of the K6-6 and K6-8 domes. 3) For the K6-6 dome, there was a 1-s transient equilibrium state following the structural vibration prior to the final collapse; this transient state was not observed in the K6-8 dome. 4) The K6-6 dome collapsed more slowly and demonstrated better progressive collapse resistance than the K6-8 dome. 5) The progressive collapse resistance and steel consumption were optimised under the condition of a rise-to-span ratio of 1/5. © 2019 Elsevier Ltd","Finite element analysis; Kiewitt-6 single-layer latticed dome; Progressive collapse; Rise-to-span ratio; Steel consumption","Arch bridges; Arches; Finite element method; Structural dynamics; Compression mechanism; Progressive collapse; Remaining component; Single-layer latticed dome; Span ratios; Steel consumption; Structural response; Structural vibrations; Domes",,,,,"2016KTZDSF04-02-02; 2019KJXX-040; National Natural Science Foundation of China, NSFC: 51608433; Natural Science Foundation of Shaanxi Province: 2018JQ5052; Science and Technology Innovation as a Whole Plan Projects of Shaanxi Province","This research was supported by the National Natural Science Foundation of China (Grant No. 51608433 ), the Science and Technology Co-ordination and Innovation Fund Project of Shaanxi Province of China (Grant No. 2016KTZDSF04-02-02 ), the Shaanxi Province Youth Science and Technology New Star Program ( 2019KJXX-040 ), and the Natural Science Foundation of Shaanxi Province of China (Grant No. 2018JQ5052 ).

It has been hypothesized that this negative pressure may cause cavitation of cerebrospinal fluid (CSF) and possibly lead to brain tissue damage from cavitation bubble collapse. The cavitation pressure threshold of human CSF is presently unknown, although existing FE studies in the literature have assumed a value of −100 kPa. In the present study, the cavitation threshold of degassed porcine CSF at body temperature (37 °C) was measured using a unique modified Polymeric Split Hopkinson Pressure Bar apparatus, and compared to thresholds of distilled water at various conditions. The loading pulse generated in the apparatus was comparable to experimentally measured pressures resulting from blast exposure, and those predicted by an FE model. The occurrence of cavitation was identified using high-speed imaging and the corresponding pressures were determined using a computational model of the apparatus that was previously developed and validated. The probability of cavitation was calculated (ISO/TS, 18506) from forty-one experimental tests on porcine CSF, representing an upper bound for in vivo CSF. The 50% probability of cavitation for CSF (−0.467 MPa ± 7%) was lower than that of distilled water (−1.37 MPa ± 16%) under the same conditions. The lesser threshold of CSF could be related to the constituents such as blood cells and proteins. The results of this study can be used to inform FE head models subjected to blast exposure and improve prediction of the potential for CSF cavitation and response of brain tissue. © 2019","Cavitation; Mild traumatic brain injury; Negative intracranial pressure; Polymeric split Hopkinson pressure bar; Porcine cerebrospinal fluid","Blood; Brain; Bridge decks; Cavitation; Polymers; Tissue; Cavitation pressure; Cavitation thresholds; Cerebro spinal fluids; Computational model; Intra-cranial pressure; Mild traumatic brain injuries; Split Hopkinson pressure bars; Split-hopkinson pressure bar apparatus; Cerebrospinal fluid; polymer; polymer; animal tissue; Article; brain tissue; cerebrospinal fluid; collapse; evaluation study; finite element analysis; in vivo study; mathematical computing; mathematical model; nonhuman; pig; priority journal; pulse rate; traumatic brain injury; animal; blast injury; cerebrospinal fluid; chemistry; computer simulation; head; head injury; male; pathophysiology; pressure; probability; temperature; Animals; Blast Injuries; Brain Injuries, Traumatic; Cerebrospinal Fluid; Computer Simulation; Craniocerebral Trauma; Finite Element Analysis; Head; Male; Polymers; Pressure; Probability; Swine; Temperature",,"Polymers",,,"Natural Sciences and Engineering Research Council of Canada, NSERC; Defence Research and Development Canada, DRDC","The authors would like to acknowledge: the Defence Research and Development Canada , Suffield Research Centre for supplying materials; the Natural Sciences and Engineering Research Council of Canada for financial support; and Compute Canada and Sharcnet for providing the necessary computing resources.",,,,,,,,,,"Ahmed, F., Gyorgy, A., Kamnaksh, A., Time-dependent changes of protein biomarker levels in the cerebrospinal fluid after blast traumatic brain injury (2012) Electrophoresis, 33, pp. 3705-3711; Alley, M.D., Schimizze, B.R., Son, S.F., Experimental modeling of explosive blast-related traumatic brain injuries (2011) Neuroimage, 54, pp. S45-S54; Altman, P.L., Blood and Other Body Fluids : Analysis and Compilation (1961), Federation of American Societies for Experimental Biology Washington, DC; Bauman, R.A., Ling, G., Tong, L., An introductory characterization of a combat-casualty-care relevant swine model of closed head injury resulting from exposure to explosive blast (2009) J.

A vibration table experiment and simulation of the finite element model (FEM) of a three-span continuous bridge with equal height piers were conducted. Then, the aseismic effect and aseismic mechanism of safe-belt device were studied by taking a five-span continuous bridge with equal height piers as an example. Finally, parameters of safe-belt device were optimized. The results show that the safe-belt device can effectively reduce the seismic responses of the fixed pier in a continuous bridge with equal height piers, but it can greatly increase the seismic responses of the sliding pier at the same time. The acceleration threshold, the tensile stiffness of the brace and the ultimate tension of the brace had great impacts on the aseismic effect of the safe-belt device, so they should be optimized according to the structural characteristics of the bridge and site conditions to obtain a better aseismic effect. The initial gap and the locking gap had little impacts on the aseismic effect of the safe-belt device. © 2019 Elsevier Ltd","Aseismic effect; Continuous bridge; Parametric analysis; Safe-belt device","Locks (fasteners); Seismic response; Acceleration threshold; Aseismic capability; Aseismic effect; Continuous bridges; Parametric -analysis; Safe-belt device; Structural characteristics; Tensile stiffness; Piers; acceleration; bridge; finite element method; parameter estimation; pier; safety; seismic response; sliding; stiffness",,,,,"National Natural Science Foundation of China, NSFC: 51778022; Natural Science Foundation of Beijing Municipality: 8172008","This work was supported by the National Natural Science Foundation of China (grant number 51778022 ) and Beijing Natural Science Foundation (grant number 8172008 ).",,,,,,,,,,"Japan Road Association, Specifications for highway, Part V, Seismic Design.

Although a three-dimensional finite element method (3-D FEM) can be used to estimate the axial leakage magnetic flux, it requires a significant amount of time for analysis. In this article, a calibration coefficient is proposed to estimate the axial leakage magnetic flux using the two-dimensional finite element method (2-D FEM) instead of 3-D FEM. This calibration coefficient is expressed in terms of the major geometric parameters of a motor and can be calculated using the material information of the permanent magnet and the bridge of the rotor core in 2-D FEM. The validity of the proposed equation is verified through 3-D FEM and other tests. © 1972-2012 IEEE.","Axial leakage magnetic flux; calibration coefficient; spoke type permanent magnet synchronous motor (spoke PMSM)","Calibration; Finite element method; Magnetic leakage; Synchronous motors; Axial leakage; Calibration coefficients; Material information; Motor performance; Permanent Magnet Synchronous Motor; Rotor structures; Three-dimensional finite-element method (3-D FEM); Two dimensional finite element method; Permanent magnets",,,,,"Gachon University: GCU-2017-0207; National Research Foundation of Korea, NRF: 2019R1C1C1011266","Manuscript received March 10, 2019; revised June 5, 2019; accepted August 21, 2019.

Based on the results of notched round bar tensile tests and finite-element analyses for Q345 steel base metal, weld metal (transverse and longitudinal), and heat-affected zone specimens, the parameters of the void growth model, stress-modified critical strain model, and cyclic void growth model were calibrated. The parameters of characteristic length in the previous models were determined by scanning electron microscope tests. The results indicated that the toughness parameters of the four materials are significantly different, and the cyclic growth capacity of the voids in weld metal and heat-affected zones deteriorates severely under cyclic loading. The toughness parameters of the two oriented weld metals are similar; therefore, the fracture toughness of the weld metal is less affected by the material orientation. The coefficients of variation of the toughness parameters of the four materials were small, and the distributions of the fracture indexes of the specimens with different notch radii were the same, which proved the effectiveness of the microscopic mechanism fracture model in predicting the initiation of ductile cracks of the members with different geometric shapes and stress states. The results of this paper provide the required material data and model parameters to predict the ductile fracture of welded joints made of Q345 steel using existing micromechanical fracture models. © 2019 American Society of Civil Engineers.","Ductile fracture; Material property; Micromechanical fracture model; Parameter calibration; Structural steel; Weld metal","Building materials; Cyclic loads; Ductile fracture; Forecasting; Fracture mechanics; Heat affected zone; Materials properties; Metal testing; Metals; Scanning electron microscopy; Tensile testing; Welded steel structures; Welding; Coefficients of variations; Micromechanical fracture modeling; Micromechanical fracture models; Microscopic mechanisms; Monotonic and cyclic loading; Parameter calibration; Structural steels; Weld metal; Fracture toughness; calibration; crack propagation; fracture; fracture toughness; micromechanics; modeling; steel; China",,,,,"National Natural Science Foundation of China, NSFC: 51421005, 51578022","This research is funded by the National Natural Science Foundation of China (NSFC) (Grants Nos. 51421005 and 51578022).

A Split Hopkinson Pressure Bar (SHPB) setup for three-point bending tests was used. Data of 20 tests were considered to be comprehensible for experimental characterization, thereby, showing an influence of strain rate on both time for fracture and amplitudes of force response. A three-dimensional porcine rib model was generated from the DICOM (Digital Imaging and Communication in Medicine) images of High-Resolution peripheral Quantitative Computed Tomography (HR-pQCT) scans. Material properties having been fitted by power law regression equations based on apparent density were assigned to the numerical rib. A modified elastic-plastic constitutive law, capable of considering the effects of strain rate was adopted. An incremental and stress-state dependent damage law, capable of considering effects of strain rate on fracture propagation, non-linear damage accumulation and instabilities was coupled to the constitutive law. The Finite Element (FE) model shows high efficiency in predicting both force-displacement curve and the fracture patterns of tested ribs. Predictions prove the ability of the proposed model to investigate the fracture behavior of human ribs under dynamic loads. © 2019","Blunt impact; Finite element simulations; Fracture; HR-pQCT; Porcine ribs; Split Hopkinson pressure bar","Behavioral research; Bending tests; Bridge decks; Computerized tomography; Dynamic loads; Elastoplasticity; Finite element method; Fracture; Fracture mechanics; Medicine; Blunt impacts; Finite element simulations; HR-pQCT; Porcine ribs; Split Hopkinson pressure bars; Strain rate; animal experiment; animal model; Article; behavior; computer assisted tomography; controlled study; cortical bone; digital imaging and communications in medicine; dynamics; experimental study; finite element analysis; force; geometry; nonhuman; oscillation; pig; prediction; priority journal; quantitative study; rib fracture; time; trabecular bone; velocity; Young modulus; animal; biomechanics; diagnostic imaging; elasticity; materials testing; physiology; rib; weight bearing; x-ray computed tomography; Animals; Biomechanical Phenomena; Elasticity; Finite Element Analysis; Materials Testing; Ribs; Swine; Tomography, X-Ray Computed; Weight-Bearing",,,,,,,,,,,,,,,,"Abdel-Wahab, A.A., Silberschmidt, V.V., Numerical modelling of impact fracture of cortical bone tissue using X-FEM (2011) J.

Remarkably, the authors explain the Resal effect in tapered beams with TCSWs, which can produce both positive and negative influences on the effective shear forces carried by the TCSWs. The Resal effect is positively correlated with the bending moment and inclined angles, and the inclined bottom flange receives a considerable proportion of the shear force near the supports with larger bending moment due to the Resal effect. Thus, the traditional calculation hypothesis that the TCSWs bear the entire vertical shear force on the cross section for prismatic cases is no longer applicable to tapered beams; the shear capacity of the concrete flanges (especially the inclined bottom flange) should not be considered negligible. Accordingly, a new theoretical formula to calculate the shear stress in a tapered beam with TCSWs is proposed by considering the Resal effect. The validity of the proposed formula is verified by comparing the theoretical predictions with the experimental and finite element (FE) analysis results. In addition, the distribution of shear stress on the top concrete flange, TCSW and inclined bottom concrete flange and the changing regularity of their respective shear bearing ratios along the span direction are experimentally and numerically analysed in this study. © 2019 Elsevier Ltd","Resal effect; Shear performance; Tapered beam; Trapezoidally corrugated steel webs","Bending moments; Bridge decks; Concretes; Fasteners; Flanges; Shear stress; Changing regularity; Concrete flange; Corrugated steel webs; Resal effect; Shear performance; Tapered beam; Theoretical formula; Variable cross section; Shear flow; finite element method; performance assessment; reinforcement; shear strength; shear stress; shear test; steel; structural component",,,,,"2019JJ50770; National Natural Science Foundation of China, NSFC: 51808559; Natural Science Foundation of Hunan Province","This study was supported by the National Natural Science Foundation of China (Grant 51808559 ).

In the heat pipe, the vapor momentum can be used to drive a mechanical structure to generate electricity. To bridge this gap, this study experimentally designed an energy harvester on the basis of a vapor-induced vibration for the innovative heat pipe application. The energy harvester, comprising a cantilever beam and polyvinylidene fluoride (PVDF), was designed using finite element method and the genetic algorithm (GA) to reach the resonance point. Copper, aluminum, and polyethylene (PE) were used as the material of the cantilever beam for the energy harvester. The optimized energy harvester was examined using a shocker, and obtained the output voltage. The output power of the harvester was affected by the vapor velocity, cantilever beam material, and natural frequency. The output voltages of the PVDF with the cantilever beam are better than the one of PVDF without the cantilever beam and it increased 367%, 393%, and 470%ascantilever beam is copper, aluminum, and polyethylene, respectively. The theoretical and practical implication, limitations of the present study for future studies are presented and studied. © 2019 Elsevier Ltd","Energy harvester; Genetic algorithm; Heat pipe; Optimization; Vapor-induced vibration","Bridges; Cantilever beams; Copper; Fluorine compounds; Genetic algorithms; Heat pipes; Nanocantilevers; Optimization; Polyethylenes; Thermoacoustics; Vibrations (mechanical); Energy Harvester; Generate electricity; Induced vibrations; Mechanical structures; Piezoelectric energy harvesters; Polyvinylidene fluorides; Resonance point; Vapor velocities; Energy harvesting",,,,,"Ministry of Science and Technology of the People's Republic of China, MOST: 107-2221-E-024-010, MOST106-2218-E-167 -002-MY2","This work was supported by the Ministry of Science and Technology of the Republic of China (MOST 107-2221-E-024-010 and MOST106-2218-E-167 -002-MY2).",,,,,,,,,,"Gupta, R.K., Shi, Q., Dhakar, L., Wang, T., Heng, C.H., Lee, C.K., Broadband energy harvester using non-linear polymer spring and electromagnetic/triboelectric hybrid mechanism (2018) Sci.

Under the effects such as earthquake, flood and wind, the most vulnerable structural elements of bridges against out-of-plane seismic motions are spandrel walls. Increasing length and height of spandrel walls increases the vulnerability of the bridge under loads in vertical and transverse directions. The aim of this research is to examine the in-plane and out-of-plane non-linear structural responses of the spandrel walls of a historical masonry bridge. For this purpose, a historical masonry arch bridge with built in 1787 in Bartın-Turkey was chosen as the subject structure. The 3D finite element model and nonlinear seismic analyses of the bridge were performed with ABAQUS. Initially, the backfill-spandrels and backfill-arch interfaces of the bridge were modeled with and without cohesive contact. The nonlinear material responses of the spandrel walls and the arch units were defined using Concrete Damage Plasticity material model and those of the backfill unit were defined with Mohr-Coulomb material model. The east-west component of 17 August 1999 Kocaeli Earthquake’s acceleration records was used in the analyses. The east-west acceleration component was applied on the bridge in-plane and out-of-plane directions during the time-history non-linear seismic analysis of the bridge. The results obtained from the analyses with and without the consideration of cohesive contact were compared to evaluate the seismic responses of the spandrel walls. As a result, cohesive interface behavior was found to significantly affect the spandrel wall response under in- plane and out-of-plane seismic forces. © 2019, Budapest University of Technology and Economics.

This current work investigates the stability behaviour of prestressed stayed steel box section columns under eccentric loading by using finite element analysis. It was demonstrated that the load carrying capacity could be decreased by the load eccentricity. A reduction factor that quantitatively denotes the effect of load eccentricity on the load carrying capacities was defined, and approximate formulae calculating the reduction factor have also been proposed. Further, it has been found that the effect of eccentricity on the load carrying capacity is significantly affected by the critical buckling modes of prestressed stayed steel columns. In addition, the effects of slenderness ratio, crossarm length, and stay diameter have also been presented in this work. The results will be of great assistance when designing this type of column under eccentric loading. © 2019 Elsevier Ltd","Approximate formulae; Eccentric loading; Finite element analysis; Prestressed stayed column","Behavioral research; Box girder bridges; Load limits; Loads (forces); Microalloyed steel; Steel construction; Approximate formulas; Eccentric loading; Effect of eccentricities; Load eccentricity; Numerical investigations; Reduction factor; Slenderness ratios; Stayed columns; Finite element method",,,,,"National Natural Science Foundation of China, NSFC: 51808070; Fundamental Research Funds for the Central Universities: 2019CDXYTM0032; Fundamental and Frontier Research Project of Chongqing: cstc2018jcyjAX0535","The research was supported by the Fundamental Research Funds for the Central Universities (No. 2019CDXYTM0032), the National Natural Science Foundation of China (No. 51808070), and the Fundamental and Frontier Research Project of Chongqing (No. cstc2018jcyjAX0535).

The static scheme of the bridge is asymmetric with one tower and three pairs of stays. The maximum span length is 21.26 m and the useful width is 2.50 m. According to the proposed design, the bridge deck will be made of glass fibre-reinforced polymer pultruded profiles; the tower and stays will be of ordinary steel; stainless steel bolts and plates will be used for the connections. A finite element model of the bridge was developed to analyse its structural behaviour during construction, service life, and maintenance operations. Construction stages – with particular attention to the cable stringing procedure – were carefully studied to help reduce the overall deformability of the bridge. Structural verifications were carried out according to the EuroComp Design Code, Italian CNR instructions, and German DIBt specifications. The calculated total weight of the bridge deck is about 11 t, including non-structural elements. Thanks to the low self-weight of the deck, a 3 kW electric motor will be sufficient for movement, with savings in both installation and operational costs with respect to a full steel bridge. © 2019 Elsevier Ltd","Cable-stayed bridge; Fibre-reinforced polymer; Pedestrian bridge; Pultruded profile; Swing bridge","Bridge decks; Cable stayed bridges; Cables; Composite structures; Fiber reinforced plastics; Footbridges; Planning; Reinforced plastics; Reinforcement; Steel fibers; Swing bridges; Feasibility studies; Fibre reinforced polymers; Glass fibre reinforced polymers; Maintenance operations; Non-structural elements; Pultruded profiles; Structural behaviour; Structural verification; Steel bridges; bridge; cable; deformation; design; feasibility study; finite element method; polymer; steel structure; Italy; Pisa [Tuscany]; Tuscany",,,,,,,,,,,,,,,,"Bank, L.C., Composites for Construction (2006), John Wiley & Sons Hoboken, NJ; Hollaway, L.C., A review of the present and future utilisation of FRP composites in the civil infrastructure with reference to their important in-service properties (2010) Constr Build Mater, 24, pp. 2419-2445; Zhao, X.-L., Zhang, L., State-of-the-art review on FRP strengthened steel structures (2007) Eng Struct, 29, pp. 1808-1823; Gholami, M., Sam, A.R.M., Yatim, J.M., Tahir, M.M., A review on steel/CFRP strengthening systems focusing environmental performance (2013) Constr Build Mater, 47, pp. 301-310; Aslam, M., Shafigh, P., Jumaat, M.Z., Shah, S.N.R., Strengthening of RC beams using prestressed fiber reinforced polymers – A review (2015) Constr Build Mater, 82, pp. 235-256; Talreja, R., Singh, C.V., Damage and failure of composite materials (2012), Cambridge University Press Cambridge, UK; Fairuz, A.M., Sapuan, S.M., Zainudin, E.S., Jaafar, C.N.A., Polymer composite manufacturing using a pultrusion process: A review (2014) Am J Appl Sci, 11 (10), pp. 1798-1810; Huo, R., Liu, W., Wan, L., Fang, Y., Wang, L., Experimental study on sandwich bridge decks with GFRP face sheets and a foam-web core loaded under two-way bending (2015) Adv Mater Sci Eng, 2015, pp. 1-12; Tuwair, H., Volz, J., ElGawady, M.A., Mohamed, M., Chandrashekhara, K., Birman, V., Testing and evaluation of polyurethane-based GFRP sandwich bridge deck panels with polyurethane foam core (2016) J Bridge Eng, 21 (1), p. 04015033; Smits, J., Fiber-reinforced polymer bridge design in the netherlands: architectural challenges toward innovative, sustainable, and durable bridges (2016) Engineering, 2 (4), pp. 518-527; Chróścielewski, J., Miśkiewicz, M., Pyrzowski, Ł., Sobczyk, B., Wilde, K., A novel sandwich footbridge - Practical application of laminated composites in bridge design and in situ measurements of static response (2017) Compos Part B-Eng, 126, pp. 153-161; Siwowski, T., Kaleta, D., Rajchel, M., Structural behaviour of an all-composite road bridge (2018) Compos Struct, 192, pp. 555-567; Siwowski, T., Kulpa, M., Rajchel, M., Poneta, P., Design, manufacturing and structural testing of all-composite FRP bridge girder (2018) Compos Struct, 206, pp. 814-827; Pyrzowski, Ł., Miśkiewicz, M., Modern GFRP Composite Footbridges (2017) 10 th International Conference on Environmental Engineering (10 th ICEE) (Vilnius, Lithuania, 27–28 April 2017), , D.

The existing uses of simple equivalent circuit models and lumped cell-level parameters are insufficient to understand the behaviors of different shunting types. This study demonstrates how the reciprocity theorem, which bridges the relationship between the terminal differential changes and local responses of a solar cell, for the current transport efficiency can be used to spatially identify ohmic and nonohmic shunt defects exemplified in CdTe solar cells. Differential electroluminescence imaging and three-dimensional finite element modeling are used to determine the current transport efficiency images. Due to the specific local differential conductance behaviors, the application of current transport efficiency imaging for the detailed analysis of different shunt defects is successfully verified in both experimental and simulation methods. In addition, the influences of two types of shunt defects on the electrical potentials and current flow of a cell are discussed. The modeling results indicate that a nonohmic shunt defect with a larger junction voltage dip and leakage current is more detrimental than an ohmic shunt defect within the cell. © 2019 WILEY-VCH Verlag GmbH & Co.

The vibration energy can be collected and converted into electric energy by installing the piezoelectric cantilever beam (PCB) harvesters on the transportation infrastructure. The resonance frequency and the resonance number of the PCB harvesters within the low frequency range play critical roles. This paper presents an analysis of four types of PCB harvesters designed according to the characteristics mentioned above to evaluate the influence of three different shapes (rectangle, trapezoid and triangle) on the power generation capacity of the piezoelectric cantilever beams. The results show that the triangular PCB harvesters are more suitable for the low-frequency vibration environment of transportation infrastructure, and they usually have higher voltage outputs. In order to widen the resonant frequency of the triangular cantilever to better adapt to the random vibration environment of the transportation infrastructure, the performance of a hollow triangular piezoelectric cantilever beam (HTPCB) was also assessed. Through modeling and analysis, the resonant frequency of the HTPCB has a broader low frequency range. In practical applications, deployment of the HTPCB harvesters on transportation infrastructures such as pavements and bridges can collect more energy in the random and low-frequency vibration environment of the transportation infrastructures. © 2019, Higher Education Press Limited Company.","Energy harvester; FEM analysis; Piezoelectric cantilever beam; Triangular","Bridges; Cantilever beams; Nanocantilevers; Natural frequencies; Organic pollutants; Piezoelectricity; Polychlorinated biphenyls; Energy Harvester; FEM analysis; Low-frequency vibration; Piezoelectric cantilever beams; Power generation capacities; Resonance frequencies; Transportation infrastructures; Triangular; Vibration analysis",,,,,,,,,,,,,,,,"Edwards, L., Bell, H.P., Comparative Evaluation of Nondestructive Devices for Measuring Pavement Thickness in the Field (2016) Inter.

This paper aims to investigate the seismic behaviour of four-legged square CFST latticed members. A total of eight latticed specimens, i.e., six with square CFST chords and circular hollow section (CHS) braces while another two with square hollow section (SHS) chords and CHS braces, were tested under combined axial compression and lateral cyclic loading. The main experimental parameters included: 1) axial compression ratio, from 0.05 to 0.5; and 2) width-to-thickness ratio of the square chord tubes, taken as 55.6 and 28.6. The experimental results clarify that the four-legged square CFST latticed specimens outperform the reference hollow steel ones in terms of hysteretic behaviour. It has also been revealed that, the well-known inward and outward buckling of chord tubes are observed for the hollow steel latticed specimens, whilst for the CFST latticed specimens, outward tube buckling at the bottom of the chords combined with cracking at the front K-shaped chord-brace connections are found to be the main failure patterns. Bearing capacity and ductility index of CFST latticed specimens increase with the decrease of axial compression ratio and chord tube width-to-thickness ratio, and the initial stiffness of CFST latticed specimens also increase with the decrease of the abovementioned two ratios. Finally, a finite element analysis (FEA) model was developed to investigate the hysteretic performance of four-legged square CFST latticed specimens, the feasibility of which was validated by comparison with the experimental results. © 2019 Elsevier Ltd","Concrete-filled steel tube (CFST); Finite element analysis (FEA); Four-legged latticed members; Hysteretic behaviour; Square hollow section (SHS)","Arch bridges; Axial compression; Beams and girders; Cyclic loads; Hysteresis; Stiffness; Tubes (components); Tubular steel structures; Circular hollow section; Concrete-filled steel tubes; Experimental parameters; Finite element analysis modeling; Four-legged latticed members; Hysteretic behaviour; Square hollow sections; Width-to-thickness ratio; Finite element method",,,,,"National Natural Science Foundation of China, NSFC: 51421064, 51678105","The financial support from the National Natural Science Foundation of China (Projects 51678105 and 51421064 ) are gratefully acknowledged.

High compressive strength, low permeability and high ductility are some of the characteristics that render UHPFRC an excellent material for repairing existing aged infrastructure. UHPFRC is most commonly applied as a surface layer for strengthening and rehabilitating concrete structures such as bridge decks or building slabs. However, its implementation with steel structures has so far been limited. In this work, the UHPFRC strengthening of a steel bridge is investigated both in simulation as well as in the laboratory, by exploiting a real-world case study: the Buna Bridge. This Croatian riveted steel bridge, constructed in 1893, repaired in 1953, and decommissioned since 2010, was removed from its original location and transported to laboratory facilities for testing prior to and after rehabilitation via addition of UHPFRC slab. The testing campaign includes static and dynamic experiments featuring state-of-the-art monitoring systems such as embedded fiber optics, acoustic emission sensors and digital image correlation. The information obtained prior to rehabilitation serves for characterization of the actual condition of the structure and allows the design of the rehabilitation solution. The UHPFRC slab thickness was optimized to deliver optimal fatigue and ultimate capacity improvement at reasonable cost. Once the design was implemented, a second round of experiments was conducted in order to confirm the validity of the solution, with particular attention allocated to the interface between the steel substrate and the UHPFRC overlay, as the connection between both materials may result in a weak contact point. A detailed fatigue analysis, based on updated FEM models prior to and after strengthening, combined with the results of a reliability analysis prove the benefits of adoption of such a solution via the significant extension of the structural lifespan. © 2019 Martín-Sanz, Tatsis, Damjanovic, Stipanovic, Sajna, Duvnjak, Bohinc, Brühwiler and Chatzi.","Fatigue; Modal analysis; Performance indicators; Reliability; Strengthening; System identification; UHPFRC",,,,,,"TU1406; Schweizerischer Nationalfonds zur Förderung der Wissenschaftlichen Forschung, SNF: 154060","The authors would like to gratefully thank the Swiss National Science Foundation (SNSF) within the context of project 154060 and the Cost Action TU1406 for their financial support.",,,,,,,,,,"(2005) Eurocode 1: Actions on Structures-Part1-4: General Actions-Wind Actions; bs en 1991-1-4: 2005, , European Committee fof Standardization; (2006) Eurocode 4: Design of Composite Steel and Concrete Structures, , European Committee for Standardization; Sia 2052. ultra-hochleistungs-faserbeton (uhfb) (2016) Baustoffe, Bemessung und Ausführung, Swiss Society of Architects and Engineers, SIA Zurich; (2011) Swiss Standards: SIA 269/3-2011 Existing Structures-Steel stuctures, , Swiss Society of Enginners adn Architects; Bajic, A., Peros, B., Meteorological basis for wind loads calculation in croatia (2005) Wind Struct, 8, pp. 389-406; Blatman, G., Sudret, B., An adaptive algorithm to build up sparse polynomial chaos expansions for stochastic finite element analysis (2010) Probabil.

Fatigue assessment of deck-to-rib welded joints under long-term train loads is an important concern for engineers. Using the stress range-number of cycles (S-N) curves that are recommended by existing specifications, it is difficult to consider welding residual stress. As a type of initial stress, welding residual stress reduces structural fatigue life by influencing the mean stress of the external cyclic load. However, the effect of mean stress is often overlooked by traditional welding fatigue theory. In this paper, a full-range S-N curve model of steel fatigue resistance integrating welding residual stress is proposed by adopting the Soderberg formula to equivalently transform the stress amplitude and mean stress. The Nanjing Dashengguan Bridge, a six-line railway steel arch bridge and the longest steel arch bridge in the world, is used as an example to demonstrate the fatigue life evaluation procedure of the proposed model in detail. First, the distribution of the welding residual stress of deck-to-rib welded details is obtained based on a refined finite-element model (FEM), and its accuracy is verified experimentally. Second, the partial welded joint model is embedded into the whole multiscale FEM of the steel deck. The structural/real stress spectrum of the welded details under a passenger/freight train is obtained by integrating the coupling effect of the train load stress and residual stress. Finally, fatigue life evaluation of the deck-to-rib welded details of the Dashengguan Bridge is carried out based on the proposed S-N curve model, integrating the residual stress and annual train volume. The results show that (1) the longitudinal residual stress (σZ) on the top and bottom surfaces of the deck vary with its welding direction respectively (perpendicular or parallel); (2) the maximum value of the real stress under the coupling effect of train load stress and residual stress is less than the yield strength (fy), so the influence of mean stress on the fatigue life of welded joints should still be considered; and (3) the fatigue life calculated by the proposed model is more accurate and conservative than a common standard. In summary, the proposed model provides a basis for determining whether the Dashengguan Bridge can allow freight trains to pass. © 2018 American Society of Civil Engineers.","Fatigue lifetime assessment; Finite-element model (FEM); Full-range stress range-number of cycles (S-N) curve; Orthotropic steel deck (OSD); Welding residual stress","Arch bridges; Arches; Bridge decks; Finite element method; Railroad transportation; Railroads; Residual stresses; Steel bridges; Welded steel structures; Welding; Welds; Complicated structures; Fatigue assessments; Fatigue life evaluation; Fatigue lifetime; Longitudinal residual stress; Number of cycles; Orthotropic steel decks; Welding residual stress; Fatigue of materials",,,,,"National Natural Science Foundation of China, NSFC: 51438002, 51508251, 51578138, 51608258; National Key Research and Development Program of China, NKRDPC: 2015CB060000; Fundamental Research Funds for the Central Universities: 2242016K41066; Scientific Research Foundation of the Graduate School of Southeast University: YBJJ1819","The authors gratefully acknowledge the National Basic Research Program of China (973 Program; Grant No. 2015CB060000), the Key Program of the National Natural Science Foundation (Grant No. 51438002), the National Natural Science Foundation (Grant Nos. 51578138, 51508251, and 51608258), the Fundamental Research Fund for the Central Universities (Grant No. 2242016K41066), and the Scientific Research Foundation of the Graduate School of Southeast University (Grant No. YBJJ1819).",,,,,,,,,,"(2004) Guide Specifications for Fatigue Evaluation of Existing Steel Bridges, , AASHTO.

In zero gravity, the static problem depends on the contact angle of the fluid segment on the solid support, and two geometric parameters: the radius ratio and the dimensionless distance between the cylinder centres. For both non-wetting and wetting liquids, we find regions of geometric parameter space where only occluding configurations occur, a bistable region where either configuration can occur, and a region where only the non-occluding bridging configuration can occur. For the non-occluding cases, we applied a large-aspect-ratio free-energy minimization approach to predict the cross-sectional shape of the liquid, and a finite element method was used to compute the interface shape of the occluding cases. A Surface Evolver model was used to simulate the three-dimensional shape of both occluding and non-occluding configurations. The simulation results support the theoretical predictions well. The fractional open area of the conduit was determined for both highly wetting and highly non-wetting minority phases. Optimization of the geometric parameters for a given wetting condition could facilitate the segregation and transport of two fluid phases in applications involving large aspect ratios and small pressure driving forces. © 2019 Cambridge University Press.","drops; liquid bridges","Contact angle; Cylinders (shapes); Drops; Free energy; Liquids; Transport properties; Wetting; Cross-sectional shape; Eccentric annuli; Equilibrium configuration; Free energy minimization; Large aspect ratio; Liquid bridge; Three-dimensional shape; Wetting conditions; Aspect ratio; bubble; droplet; eccentricity; equilibrium; fluid dynamics; optimization; simulation; wetting; Gastropoda",,,,,,,,,,,,,,,,"Blackmore, W., Weislogel, M.M., Chen, Y., Kiewidt, L., Klatte, J., Bunnell, C.T., The capillary flow experiments (CFE-2) on ISS: Status (2011) 49th AIAA Aerospace Sciences Meeting, , American Institute for Aeronautics and Astronautics; Bostwick, J.B., Steen, P.H., Stability of constrained capillary surfaces (2015) Annu.

Boyd St., Room 334, Norman, OK  73019-1024, United States","Currently, there is a limited amount of published information on failures of prestressed concrete bridges subjected to shear and moment. A scale prestressed concrete bridge was constructed to investigate the ultimate behavior of the bridge with particular focus on load distribution after cracking and on contribution of full-depth diaphragms to structural capacity. A point load was applied at the quarter-span point of the bridge over an interior girder. As the loaded girder failed, the diaphragm-girder connection cracked. Torsion was observed to cause cracking in the exterior girder and the end diaphragm rotated away from the bridge as the deck deformed. A punching shear failure ended the test, however damage indicative of two-way slab behavior was observed in the deck. This failure suggests that post girder failure, the diaphragms provide an important means of load transfer, allowing moment redistribution in the deck and potentially increasing capacity. Testing in the elastic range compared favorably with respect to deflections and shear distribution factors from a grillage model, a 2-D finite element model and a 3-D finite element model. © 2019 Elsevier Ltd","Bridges; Destructive; Distribution factors; Prestressed concrete; Shear; Two-way slab","Bridges; Computer testing; Concrete beams and girders; Concrete bridges; Concrete testing; Diaphragms; Finite element method; Shearing; 3D finite element model; Destructive; Distribution factor; Increasing capacities; Moment redistribution; Shear distributions; Structural capacities; Two-way slab; Prestressed concrete; bridge; concrete structure; cracking (fracture); damage; deformation; elasticity; finite element method; shear stress; testing method",,,,,"Oklahoma Department of Transportation, ODOT","This research was funded by the Oklahoma Department of Transportation (ODOT) .

This paper presents the framework and application of Level 2 safety evaluation of CFST arch bridges, incorporating structural health monitoring (SHM) and inspection information. In contrast with the traditional inspection-based qualitative assessment and direct measurement-based quantitative assessment for SHM, Level 2 safety evaluation considers the inevitable resistance deterioration and site-specific loading under normal operation conditions. For such safety evaluations, the most important element is using the well-established finite element modelling for representing the actual conditions as accurately as possible. Thus, in this study, component and global finite element model (FEM) updating techniques are employed to ensure the local and global behaviour of the updated FEM, through which several types of common CFST arch bridge defects are investigated and updated. Measured site-specific live loads experienced by CFST arch bridges are considered and transformed into design loads for comparison. Unfavourable load patterns are applied to the updated FEM for structural reanalysis, to evaluate the component safety status, and gradually increasing unfavourable load patterns are applied to the FEM to perform an ultimate load-bearing analysis to obtain the global safety reservation. Level 2 safety evaluation is conducted by considering modal parameters, displacements, fatigue damage, and component and global safety status. Level 2 safety evaluation is applied to a typical CFST arch bridge, to demonstrate the entire evaluation process and the effectiveness of the proposed safety evaluation framework. © 2018 John Wiley & Sons, Ltd.","CFST arch bridge;

The concept consists of two clamped structures: 1) a press-pack power stage accommodating SiC power switch dies and 2) perpendicularly clamped press-pack heatsinks, in which the heatsinks are in contact with electrically insulated case plates of the power stage. The concept enables bondless package with symmetric double-sided cooling of the dies and allows for an order of magnitude higher clamping force on the heatsinks than what can be applied on the dies. The concept has been evaluated in a first demonstrator (half-bridge configuration with 10 paralleled SiC dies in each position). The experimental methodologies, setups, and procedures have been presented. The commutation loop inductance is approximately 9 nH at 78 kHz. The junction-to-case thermal resistance is approximately 0.028 K/W. Furthermore, a simplified 3-D finite-element thermomechanical model representing the center unit of the demonstrator has been established for the purpose of future optimization. The accuracy of the simulated temperatures is within 4% compared to the measurements. Finally, a 3-D thermomechanical stress distribution map has been obtained for the simplified model of the demonstrator. © 2011-2012 IEEE.","Computational fluid dynamics (CFD); electromagnetic analysis; finite-element analysis (FEA); inductance; measurement techniques; power electronics; power electronics packaging; press-pack technology; silicon carbide (SiC); thermal resistance; thermomechanical simulation","Carbide dies; Computational electromagnetics; Computational fluid dynamics; Electric power systems; Electronics packaging; Heat resistance; Heat sinks; Inductance; Power electronics; Power semiconductor devices; Presses (machine tools); Silicon carbide; Electromagnetic analysis; Experimental methodology; High power applications; Measurement techniques; Press pack; Silicon-carbide power devices; Thermo-mechanical stress; Thermomechanical simulation; Finite element method",,,,,"Energimyndigheten","Manuscript received June 9, 2018; revised September 16, 2018; accepted September 21, 2018.

Visual inspection and load testing of this double tee structure indicated a severely deteriorated deck, undamaged girder stems, and partially effective transverse connections at the longitudinal joints. At the time of testing, the bridge was load-posted at 35.6 kN (total gross vehicle weight) with a maximum speed of 8 km/h due to conservative rating assumptions. After a detailed analysis, a truck that was 7.5 times the posted weight was used for a load test. A shell-based finite-element model was created that used variable spring elements to model the deteriorated flange-to-flange connections, which accurately replicated the behavior of the bridge from the load test and validated the modeling technique. The model was used to perform a parametric study, using idealized flange-to-flange connections, to compare the calculated girder distribution factors to the finite-element model-estimated girder distribution factors, and poor agreement was found (R2=0.449 and 0.237 for moment and shear, respectively). A multivariable linear regression analysis was used to develop moment and shear girder distribution factor equations for double tee bridges similar to the one investigated in this study, with a much better correlation of R2=0.86 and 0.83 for moment and shear, respectively. © 2018 American Society of Civil Engineers.","Double tee bridge; Girder distribution factor; Multivariable linear regression; Parametric study","Automobile testing; Beams and girders; Deterioration; Flanges; Highway bridges; Load testing; Regression analysis; Analytical investigations; Double-tee; Girder distribution factors; Gross vehicle weight; Live-load behavior; Multi-variable linear regression; Parametric study; Significant deteriorations; Finite element method",,,,,"DTFH61-08-C-00005","This publication was partially supported by a subcontract from Rutgers University, Center for Advanced Infrastructure & Transportation, under DTFH61-08-C-00005 from the U.S. Department of Transportation—Federal Highway Administration (USDOT-FHWA).

Taking three different representative volume elements into account, the geometric description of 3D braided preform is established with the assumptions that the braided yarns with the circle cross-section keep straight in the interior, bend and change linearly to other directions at the surface and corner regions. After that, all yarns are divided into segments and classified into eight groups according to centreline of segment orientations, which leading to easily assign material orientations and properties for transversely isotropic constitutive of yarns. Considering the different yarns jamming effect in different regions, the model involves the various diameters for yarns in the three regions, which also can ensure no interpenetrations among yarns. What's more, a mesoscale finite element model involving matrix pockets is developed for 4-step three-dimensional rectangular braided composites subjected to a steel ball with an initial velocity of 200 m/s in LS-DYNA to validate its practicality. © 2018 Elsevier Ltd","3D braided composites; Automatically; Finite element model; Mesoscale structure","Composite materials; Preforming; Yarn; 3-d braided composites; Automatically; Geometric description; Meso-scale finite element models; Mesoscale structure; Representative volume element (RVE); Three-dimensional braided composites; Transversely isotropic; Finite element method",,,,,"National Natural Science Foundation of China, NSFC: 51475227, 51605218; Nanjing University of Aeronautics and Astronautics, NUAA: 180902DF02; Fundamental Research Funds for the Central Universities: NS2016029","The authors wish to thank Shanying Xu and Hailang Hu for assisting MATLAB study and gratefully acknowledge the financial support by the National Natural Science Foundation of China General under number 51475227 ; the National Natural Science Foundation of China under Grant number 51605218 ; the Fundamental Research Funds for the Central Universities under Grant number NS2016029.

In this study, we analyzed the dynamic response of different types of concrete-beam bridges (continuous beam and simply supported beam) with different cross-sectional designs (T-beam and hollow-slab beam) under vibratory compaction of bridge deck asphalt pavement. The dynamic response patterns of the dynamic deformation and acceleration of bridges under pavement compaction were obtained by performing a series of field experiments and a three-dimensional finite element simulation. Based on the finite element model, the dynamic responses of bridge structures with different spans and cross-sectional designs under different working conditions of vibratory compaction were analyzed.

The structural behavior was investigated through the failure modes and cracking patterns to show the anchorage zone resistance enhancement with an increase of the strength in concrete. Since the anchorage failure is usually initiated from the local zone in the case of ultra-high-performance concrete beams that have compressive strength of more than 80 MPa, the placement of reinforcements can effectively be used to enhance the strength and ductility for the local zone. However, ultra-high-performance concrete requires a smaller amount of reinforcement than normal-strength concrete. Parametric analyses are carried out to show the effect of the spiral reinforcement on the strength of the anchorage zone, and comparison with the design guidelines in NCHRP Report 356 is made. Finally, improved guidelines are suggested to cover the design of ultra-high-performance concrete. © The Author(s) 2018.","anchorage zone; design guideline; local zone; ultimate strength; ultra-high-performance concretes","Anchorage zones; Anchorages (foundations); Box girder bridges; Compressive strength; Concrete beams and girders; Concrete reinforcements; Design; Finite element method; Local zones; Normal strength concretes; Resistance enhancement; Spiral reinforcements; Strength and ductilities; Three dimensional finite element analysis; Ultimate strength; Ultra high performance concretes; High performance concrete",,,,,"Ministry of Land, Infrastructure and Transport, MOLIT; National Research Foundation of Korea, NRF; Korea Agency for Infrastructure Technology Advancement, KAIA; Ministry of Science and ICT, South Korea, MSIT: 13SCIPA02, 2017R1A5A1014883","The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This work was supported by the National Research Foundation of Korea (NRF) Grant funded by the Korean Government (MSIT; No. 2017R1A5A1014883), by a grant (13SCIPA02) from Smart Civil Infrastructure Research Program funded by Korea Agency for Infrastructure Technology Advancement (KAIA), and by Korea Ministry of Land, Infrastructure and Transport (MOLIT) as ‘‘U-City Master and Doctor Course Grant Program.’’",,,,,,,,,,"(2012) AASHTO LRFD Bridge Design Specifications, , Washington, DC, American Association of State Highway and Transportation Officials; Axson, D.P., (2008) Ultimate Bearing Strength of Post-Tensioned Local Anchorage Zones in Lightweight Concrete, , Master’s Thesis, Virginia Polytechnic Institute and State University, Blacksburg, VA; Bonetti, R., Roberts-Wollmann, C.L., Santos, J.T., Bearing strength of confined concrete (2014) ACI Structural Journal, 111, pp. 13-17; Breen, J.E., Burdet, O., Roberts, C., (1994) Anchorage Zone Reinforcement for Post-Tensioned Concrete Girders, , Washington, DC, Transportation Research Board; (1993) CEB-FIP Model Code 1990: Design Code, , London, Thomas Telford Ltd; Cervenka, V., Ganz, H.R., Validation of post-tensioning anchorage zones by laboratory testing and numerical simulation (2014) Structural Concrete, 15, pp. 258-268; (2010) Documentation A and manual U (version 6.10), , Vélizy-Villacoublay, Dassault Systèmes; (2002) Guideline for European Technical Approval of Post-Tensioning Kits for Prestressing of Structures, , Brussels, European Organisation for Technical Arovals; (2004) Design of concrete structures part 1-1: general rules for buildings; Graybeal, B., (2011) Ultra-High Performance Concrete, , New York, Portland Cement Association; Kim, J.S., Choi, Y.S., Stress analysis of PS anchorage zone using ultra high performance concrete (2013) Journal of the Korean Society of Civil Engineers, 33, pp. 1349-1360; Kim, J.S., Kwark, J.W., Joh, C.B., (2011) Development of Design Guide of PS Anchorage Using Ultra High Performance Concrete, , Seoul, Korea, Seokyeong University; (2016) Design Recommendations for Super Concrete, , Seoul, Korea, Ministry of land, Infrastructure and Transport; Kwon, Y.S., Kim, J.K., Kwak, H.G., Ultimate strength of anchorage zone according to geometric parameters of post-tensioning anchorage using a finite element method (2015) Journal of Computational Structural Engineering Institute of Korea, 28, pp. 317-324; Lee, I., (2002) Complete Stress-Strain Characteristics of High Performance Concrete, , Newark, NJ, New Jersey Institute of Technology; Lee, J., Fenves, G.L., Plastic-damage model for cyclic loading of concrete structures (1998) Journal of Engineering Mechanics, 124, pp. 892-900; Leutbecher, T., Fehling, E., (2004) Structural behaviour of UHPC under tensile stress and biaxial loading, pp. 435-446. , Proceedings of the international symposium on ultra high performance concrete, Kassel, Kassel, Kassel University Press GmbH, In; Niyogi, S.K., Concrete bearing strength-support, mix, size effect (1974) Journal of the Structural Division, 100, pp. 1685-1702. , PTI (Post-Tensioning Institute) (2006) Post-tensioning manual.

Previous experimental and numerical studies revealed that the damages of this bridge type under across-fault ground motions mainly concentrate on the two CFDST piers.This paper investigates the effectiveness of damage mitigation measures for the SCCRFB with CFDST piers by using numerical simulations. Three detailed three-dimensional (3D) finite element (FE) bridge models are developed by using the explicit FE code LS-DYNA, in which Model A represents a reference SCCRFB with CFDST piers, and Models B and C employ different stiffeners at the two ends of the CFDST piers aiming to mitigate the damages induced by the effect of across-fault ground movements. Two pairs of across-fault ground motions with thrust and strike-slip mechanisms are considered, and the influence of fling-step is parametrically investigated. Numerical results including structural damages and responses are presented and the damage mechanisms are analyzed. Numerical results indicate that the strengthening measure used in Model C can effectively restrain local buckling of the steel tubes under both types of across-fault ground motions and is a practical option for SCCRFB with CFDST piers to mitigate the potential fault-crossing hazard. This study provides useful references for the seismic design of SCCRFB with CFDST piers crossing active faults. © 2020, Springer Nature B.V.","Across-fault ground motions; Damage mitigation; Fling-step effect; Numerical simulation; SCCRFB with CFDST piers; Seismic response","Composite structures; Piers; Rigidity; Seismic design; Seismic waves; Seismology; Strike-slip faults; Tubular steel structures; Bridge constructions; Concrete filled doubleskin steel tube (CFDST); Damage mitigation measure; Experimental and numerical studies; Rigid-frame bridges; Strike-slip mechanism; Structural solutions; Threedimensional (3-d); Concretes; active fault; bridge; buckling; composite; concrete; damage mechanics; fault; finite element method; ground motion; numerical method; performance assessment; seismic design; seismicity; steel; three-dimensional modeling",,,,,"KYCX17_0128; National Natural Science Foundation of China, NSFC: 51678141; China Scholarship Council, CSC; National Key Research and Development Program of China, NKRDPC: 2017YFC0703405; Fundamental Research Funds for the Central Universities","This study was supported by the National Natural Science Foundation of China (No. 51678141) and the National Key Research and Development Program of China (No. 2017YFC0703405).

Field tests were performed, analyzing accelerations, velocities and displacements in the track and subgrade. Based on the field test results, the influences of the train types, driving direction and running speed on the dynamic response in the transition zone were investigated. A 3D finite element model considering vehicle-track-subgrade coupled interactions was presented, and the results from the model were compared with the measured responses. Based on the model, the distribution of the vertical dynamic stress in the subgrade was analyzed, and the running quality for the comfort of passengers on the train and the dynamic response along the DBPPS transition zone with alternative fillings in the subgrade, such as graded gravel and AB group filling (well graded coarse-grained soil with less than 30% fine-grained soil), were discussed.

In this paper, a simplified forward isolated converter topology with an integrated planar transformer is proposed, which eliminates the need of output filter inductor while rearranging the clamp circuit for reduced components ratings and voltage stress in a cost-effective solution. The proposed single-switch forward converter topology employs switch protection and transformer core demagnetization with Zener diode voltage-clamped circuit. Through the converter analysis, the switching frequency has been selected in relationship to the transformer inductance and the equivalent circuit capacitance for the benefit of soft-switching devices transitions. The converter features multiple isolated secondaries necessary for independent gate-driver voltage supplies in multi-level converters. Specifically, the proposed converter provides voltage supplies for a gate-driver power devices pair, such as half-bridge SiC devices. The integrated solution reduces the total number of gate-drivers transformers necessary in multilevel-based 1500V converters. The simulation and experimental results are obtained from a gate-drive application platform to demonstrate the validity of the proposed isolated dc-dc converter design with integrated planar transformer. © 2020 IEEE.","Finite element analysis (FEA); gate-driver power supply; inductorless forward converter topology; isolated forward planar transformer; reinforced isolation for 1500V converters","Capacitance; Cost effectiveness; DC transformers; Energy conversion; Equivalent circuits; Frequency converter circuits; Power semiconductor devices; Silicon carbide; Silicon compounds; Switching frequency; Topology; Transformer protection; Wide band gap semiconductors; Application platforms; Cost-effective solutions; Gate-driver power supplies; High-performance operation; Isolated dc-dc converters; Multilevel converter; Output filter inductors; Single-switch forward converters; DC-DC converters",,,,,,,,,,,,,,,,"Serban, E., Ordonez, M., Pondiche, C., Dc-bus voltage range extension in 1500 v photovoltaic inverters (2015) Ieee J.

Many of them did not take into account the sensitivity of the updating parameters to the model outputs. Therefore, in this paper, optimization algorithms and sensitivity analysis are applied for model updating of a real cable-stayed bridge, i.e., the Kien bridge in Vietnam, based on experimental data. First, a global sensitivity analysis using Morris method is employed to find out the most sensitive parameters among twenty surveyed parameters based on the outputs of a Finite Element (FE) model. Then, an objective function related to the differences between frequencies, and mode shapes by means of MAC, COMAC and eCOMAC indices, is introduced. Three metaheuristic algorithms, namely Gravitational Search Algorithm (GSA), Particle Swarm Optimization algorithm (PSO) and hybrid PSOGSA algorithm, are applied to minimize the difference between simulation and experimental results. A laboratory pipe and Kien bridge are used to validate the proposed approach. Efficiency and reliability of the proposed algorithms are investigated by comparing their convergence rate, computational time, errors in frequencies and mode shapes with experimental data. From the results, PSO and PSOGSA show good performance and are suitable for complex and time-consuming analysis such as model updating of a real cable-stayed bridge. Meanwhile, GSA shows a slow convergence for the same number of population and iterations as PSO and PSOGSA.

The evaluation of the behavior of masonry arch bridges has drawn a great deal of attention over the past years due to the increase in the speed of railway fleet, need for augmentation of trains axle loads, and increase in the number of vehicles. These critical structures have been designed for service loads demanded at past times and since service loads are different in the present time, their behavior crucially needs to be assessed. Various analytical, experimental, approximate, and numerical methods have been proposed so far to estimate the residual capacity of masonry arch bridges. The present paper aims to predict the maximum service load of railway plain concrete arch bridges using a new approach with the aid of stress intensity factor in the fracture mechanics. Since stress intensity factor is solved analytically only for highly simple problems, a numerical approach and the finite element method were used in the present paper to calculate this parameter. Finally, given the stress intensity factor and proposing a relation for concrete toughness based on a statistical study, the maximum service load of these vital structures is obtained. To validate the results, two plain concrete arch bridges —located at kilometer 23 and 24 of Tehran-Qom Old Railway— were used. The results revealed that the proposed method has agreed well with the field observations. © 2020 Institution of Structural Engineers","Concrete fracture toughness; Cracked structures; Old railway arch bridges; Safety evaluation; Service load capacity; Statistical study; stress intensity factor (SIF)",,,,,,,,,,,,,,,,,"Mohammadi, S., Extended finite element method: for fracture analysis of structures (2008), John Wiley & Sons; Liebowitz, H., Moyer, E.T., Jr, Finite element methods in fracture mechanics (1989) Comput Struct, 31, pp. 1-9; Moës, N., Dolbow, J., Belytschko, T., A finite element method for crack growth without remeshing (1999) Int J Numer Meth Eng, 46, pp. 131-150; Portela, A., Aliabadi, M.H., Rooke, D.P., Dual boundary element incremental analysis of crack propagation (1993) Comput Struct, 46, pp. 237-247; Saleh, A.L., Aliabadi, M.H., Crack growth analysis in concrete using boundary element method (1995) Eng Fract Mech, 51, pp. 533-545; Sukumar, N., Moës, N., Moran, B., Belytschko, T., Extended finite element method for three-dimensional crack modelling (2000) Int J Numer Meth Eng, 48, pp. 1549-1570; Cox, J.V., An extended finite element method with analytical enrichment for cohesive crack modeling (2009) Int J Numer Meth Eng, 78, pp. 48-83; Rajagopal, S., Gupta, N., Meshfree modelling of fracture—a comparative study of different methods (2011) Meccanica, 46, pp. 1145-1158; Yang, Z., Fully automatic modelling of mixed-mode crack propagation using scaled boundary finite element method (2006) Eng Fract Mech, 73, pp. 1711-1731; Khaji, N., Yazdani, M., Determination of stress intensity factors of 2D fracture mechanics problems through a new semi-analytical method (2016) Fatigue Fract Eng Mater Struct, 39, pp. 467-478; Yazdani, M., Khaji, N., Khodakarami, M.I., Development of a new semi-analytical method in fracture mechanics problems based on the energy release rate (2016) Acta Mech, 227, pp. 3529-3547; Henshell, R.D., Shaw, K.G., Crack tip finite elements are unnecessary (1975) Int J Numer Meth Eng, 9, pp. 495-507; Wang, J., Melbourne, C., Mechanics of MEXE method for masonry arch bridge assessment (2010) Proc Inst Civ Eng – Eng Comput Mech, 163 (3), pp. 187-202; Heyman, J., The safety of masonry arches (1969) Int J Mech Sci, 11, pp. 363-385; Crisfield, M., Packham, A., (1987), A mechanism program for computing the strength of masonry arch bridges, in; Choo, B.S., Coutie, M.G., Gong, N.G., Finite-element analysis of masonry arch bridges using tapered elements (1991) Proc – Inst Civ Eng.

Then, selected solution is directly tested in a mandatory fire-test. Unfortunately, few pieces of information could be retrieved either if the test succeeds or fails, which makes both improvements in the design and use of innovative materials difficult. Thus, in this work, a self-consistent finite element method (FEM) analysis is developed and assessed against experimental fire-test results, highlighting the critical parameters affecting the numerical simulations. Using this tool, a new fiberglass-containing foam, with improved acoustic and mechanical properties, as compared to the rock-wool, is studied as a potential insulating material for on-board fire-doors. The assessment of the performance of the new material demonstrates that, contrary to common believe, the effective thermal insulation capacity is not necessarily the critical factor in determining the fire-resistance of a fire-door. Using the validated FEM analysis, it has been proven that the reduction of the thermal bridges originated at the door edges allows, firstly, for the attainment of a fire-door 37% thinner and 61% lighter with respect to a traditional one, and, secondly, the use of new material as insulator in fire-doors that, even if less thermally capable, could improve other properties of the door, as an example its soundproofing. © 2020 by the authors.","Finite element analysis; Fire-resistance test; Innovative insulator; Marine fire-doors; Thermal bridges; Thermo-mechanical analysis",,,,,,,,,,,,,,,,,"(2010) Annex 1, Part 3, , International Maritime Organization (IMO): London, UK; Moro, L., De Bona, F., Gasparetto, A., Novak, J.S., Boscariol, P., Innovative design of fire doors: Computational modeling and experimental validation (2017) Fire Technol., 53, pp. 1833-1846; Asdrubali, F., D'Alessandro, F., Schiavoni, S., A review of unconventional sustainable building insulation materials (2015) Sustain.

Firstly, photos and videos regarding the collapse site were collected to analyze the possible causes of the collapse. Secondly, the three-dimensional FEM of Heyuan Dongjiang Bridge were established based on the information and videos of the collapse. Thirdly, the collapse process of Heyuan Dongjiang Bridge was inversely analyzed based on the finite element model (FEM); finally, the site data, collapse videos and finite element simulation results were combined to comprehensively analyze the causes for the collapse of Heyuan Dongjiang Bridge. The results showed: the performance degradation of main arch ring's material and the foundation displacement were the major causes of the collapse of Heyuan Dongjiang Bridge. Accordingly, it was recommended to test and evaluate the performance of the main arch ring materials of deck type arch bridges on service for a long time; and check the displacement of the piers (abutment) in segments of rushing water. © 2020 Elsevier Ltd","Collapse simulation; Finite element analysis; Masonry arch bridge; Nonlinearity","Accidents; Arch bridges; Arches; Disasters; Arch rings; Finite element simulations; Foundation displacement; Inversion analysis; Performance degradation; Site investigations; THREE-DIMENSIONAL FEM; Finite element method",,,,,"National Natural Science Foundation of China, NSFC: 51408453; Natural Science Foundation of Shaanxi Province: 2020JM-475; Education Department of Shaanxi Province: 15JK1422","The financial support of National Natural Science Foundation of China (Grant Nos. 51408453 ) and Provincial Natural Science Foundation of Shaanxi (Grant Nos. 2020JM-475 ) and Science Research Program of Education Department of Shaanxi Province (Grant Nos. 15JK1422 ).

In this paper, the lateral-torsional buckling is analytically studied for a simplified S-shaped serpentine structure that consists of five straight components rigidly connected at point joints. Simple analytic scaling laws between the dimensionless critical buckling load and the aspect ratio of the serpentine structure are newly derived and uniformly expressed in terms of generalized hypergeometric series for various types of boundary conditions, which can serve as the benchmark of numerical simulations. These scaling laws, fully verified by finite element analysis, may well capture the implied connection between stretching- and compression-induced buckling, the strong dependence of buckling modes on end conditions, and the monotonic/asymptotic properties of the critical load with respect to the aspect ratio of serpentine structures.

Based on this, this paper proposes an improved artificial fish school algorithm. By combining the niche technology with the artificial fish school algorithm, the improved algorithm can systematically find multiple global optimal solutions and local optimal solutions of the objective function. Aiming at the difficulty of determining the niche radius, an adaptive niche radius mechanism is proposed. The improved algorithm is used to study the multi-alternatives problem of finite element model updating after verifying its feasibility through numerical simulation analysis. In the case of benchmark framework model updating, it is confirmed that multi-alternative problems exist and the global optimal solution of the objective function does not necessarily represent the true parameters of the structure. In case 2, the improved algorithm combined with the Kriging model is applied to the model updating of a cable-stayed footbridge, and 15 sets of solutions are obtained, in which the error objective function values of the measured and theoretical values of the bridge modes are close but the solutions are completely different. Combining with the actual bridge condition and reanalysis technology, the author takes the suboptimal solution 2 as the most representative solution of the bridge parameters, which reduces the possibility of misjudgment of structural parameters. © 2020 by the authors.

The computational efficiency of some current methods for determining the critical angle needs to be improved and their applicability in practical engineering projects remains to be examined. For this reason, a resultant response-based (RRB) method is developed herein for assessing the critical excitation direction of curved bridges. To validate the feasibility of this method in an actual seismic design context, a 1/62.5-scale model of a three-span curved bridge is designed and a multi-angle shaking table test is implemented. Meanwhile, the finite-element model of the test specimen is set up, and the RRB method as well as the linear response-history analysis (LRHA) are comparatively assessed. The results indicate that the RRB method can capture the critical excitation direction of curved bridges with sufficient precision (error does not exceed 10% compared to LRHA). The associated computational effort is also substantially reduced given that RRB requires analysis solely along two orthogonal directions as the incidence angles, compared to standard response history analyses where ground motion excitation is applied at multiple ground motion orientations. The above observation is further verified by a well-designed experimental campaign, which demonstrates the accuracy and practicability of the RRB method for the case of realistic bridge configurations. © 2020 Elsevier Ltd","Critical excitation directions; Curved bridges; Response spectrum; Resultant response; Shaking table","Computation theory; Computational efficiency; Seismic design; Seismology; Computational effort; Experimental campaign; Experimental verification; Ground-motion excitation; Orthogonal directions; Practical engineering; Response history analysis; Response-based method; Bridges; bridge; finite element method; ground motion; seismic design; seismic response; shaking table test; theory",,,,,"2016C0006; National Natural Science Foundation of China, NSFC: 51778471, 51978512; Ministry of Science and Technology of the People's Republic of China, MOST: SLDRCE19-B-19; China Scholarship Council, CSC","This research was supported by the National Natural Science Foundation of China under Grant No. 51778471, 51978512; the Ministry of Science and Technology of China under Grant No. SLDRCE19-B-19; and Science and Technology Project of Communications Department of Jiangxi Province under Grant No. 2016C0006.

Based on the case of the Lezíria Bridge in Portugal, one of the most comprehensive case studies available in the literature, a set of good practices to achieve reliable assessments on the long-term behavior is outlined. Spanning the construction phase, the loading test (at the end of construction) and the operation phase, the behavior of the bridge is well predicted for several physical parameters. Nevertheless, the extrapolation of creep and shrinkage models, the influence of interior and exterior environments, and significant thickness variations along cross-sections are key issues that deserve special attention. The role of advanced FE modeling supported by monitoring data is showed to be one of the most robust approaches for supporting the management of large civil infrastructures in this era of digitalization (Industry 4.0). © 2020 fib.

Unfortunately, this bending behavior has been barely investigated which limits the design of BMCVSs with optimal structures. Herein, six BMCVSs were designed and their bending process were simulated using finite element analysis (FEA). Then, the effects of the stent bridge connection type and structure on the bending behavior were systematically analyzed and an universal mathematical model was further established, in which the influence of the structure parameters of the stent bridge on the flexibility of stents was considered. After that, the bending mechanism of the high-stress zone of the bridge was investigated. Finally, the causes and effects of the self-contacting phenomenon as well as the inner-stent protrusion phenomenon in the bending state were analyzed theoretically, and corresponding solutions were proposed to optimize the design of stents. The numerical results show that the stents with the dislocation-line W-shaped unit have better flexibility than the other stents. The flexibility is positively correlated to the cube of the length of linear part and to the square of the curvature of curved part. The self-contacting phenomenon of the bridge during bending can constrain the formation of inner-stent protrusion, which can eliminate the negative effects of the implanted stents on the hemodynamics in blood vessels. This study is expected to provide practical guidance for the structural design of BMCVSs for clinical applications. © 2020 Elsevier Ltd","Bending behavior; Biodegradable; Cerebral vascular stent; Finite element analysis; Flexibility","Blood; Blood vessels; Finite element method; Stents; Structural optimization; Bending mechanism; Biodegradable metals; Bridge connections; Clinical application; Corresponding solutions; Optimal structures; Practical guidance; Structure parameter; Structural design; Article; brain blood vessel; correlational study; finite element analysis; force; mathematical model; physical parameters; priority journal; process optimization; stress; finite element analysis; hemodynamics; mechanical stress; prosthesis design; stent; theoretical model; Finite Element Analysis; Hemodynamics; Models, Theoretical; Prosthesis Design; Stents; Stress, Mechanical",,,,,"MMT2017-03; National Natural Science Foundation of China, NSFC: 11502044; National Key Research and Development Program of China, NKRDPC: 2018YFA0703000; Fundamental Research Funds for the Central Universities: DUT17RC (3)104, DUT19ZD202","The authors greatly appreciate the financial support by the National Key Research and Development Program of China ( 2018YFA0703000 ), the National Natural Science Foundation of China ( 11502044 ), the Fundamental Research Funds for the Central Universities ( DUT17RC (3)104 , DUT19ZD202 ) and Open Project Fund of National Center for International Research of Micro-Nano Molding Technology & Key Laboratory for Micro Molding Technology of Henan Province (MMT2017-03).",,,,,,,,,,"Alherz, A.I., Tanweer, O., Flamini, V., A numerical framework for the mechanical analysis of dual-layer stents in intracranial aneurysm treatment (2016) J.

The American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) provides a formula for calculating the load distribution factor (LDF), which is a key parameter in determining the internal force distribution in multi-girder bridges under live loads. To evaluate the performance of the AASHTO LRFD formula, the rigid-jointed girder (RJG) method is employed to obtain the transverse distribution influence line of each girder by considering the influence of the transverse connection beams, which is validated by field tests and finite element analysis. Based on the traversal algorithm composed of rough and refined calculations, LDF for moment can be obtained using the transverse distribution influence lines. In addition, information on 120 bridges, including 99 bridges in the literature and 21 actually built bridges designed or recommended by our research group, is collected for parametric analysis. On the basis of the parametric analysis, the relationship between LDF and the key parameters is determined, which helps derive an improved formula to calculate the LDF. Moreover, approximately 58% bridges’ errors exceed 10% based on the AASHTO formula, some of which even reach 30%. Compared with the AASHTO formula, only 5% bridges remain whose error exceeds 10% based on the improved formula for exterior girders. The improved formula for interior girders is the same as the former which is safe and precise because more than 80% bridge bridges’ errors are less than 10%. To sum up, the improved formula is found to be superior with higher accuracy and solid physical foundation. © 2020 Elsevier Ltd","AASHTO LRFD; Composite bridges; Evaluation and improvement; Load distribution factor; Multi-box; Rigid-jointed girder method","Beams and girders; Box girder bridges; Bridge decks; Composite bridges; Electric power plant loads; Errors; Internal force distributions; Load and resistance factor designs; Load distribution factor; Mechanical behavior; Multi-girder bridges; Parametric -analysis; Transverse distribution influence lines; Traversal algorithms; Structural dynamics; algorithm; bridge; composite; concrete structure; finite element method; steel structure",,,,,"K2018G018; National Natural Science Foundation of China, NSFC: 51878378; National Science Fund for Distinguished Young Scholars: 51725803","This research is funded by the National Science Fund for Distinguished Young Scholars (Grant No. 51725803 ), National Natural Science Foundation of China (Grant No. 51878378 ) and Key Research Program of China Railway Corp.

Corrosion at the surface of WHSJs has significantly different influences on the compression capacity of WHSJs, depending upon its location. Pit corrosion is a typical corrosion type for steel structures, but the influence of pit corrosion at different locations on the loading capacity of WHSJs has not been quantified. This study determined the influence of corrosion located in different places on the compression capacity of WHSJs. The influence of corrosion location on compression capacity was systematically investigated. The accuracy of the finite-element (FE) model was validated. The influence of corrosion and geometrical parameters on the random distribution of compression capacity was analyzed. A simplified method to predict the compression capacity is proposed. © 2020 American Society of Civil Engineers.","Artificial corrosion; Compression capacity; Corrosion location; Experiment; Welded hollow spherical joints","Bridge decks; Experiments; Geometry; Location; Welding; Compression capacity; Corrosion types; Loading capacities; Pit corrosion; Random distribution; Reticulated shell structure; Simplified method; Welded hollow spherical joints; Steel corrosion; accuracy assessment; compression; corrosion; experimental study; finite element method; geometry; loading; quantitative analysis; structural analysis",,,,,"China Postdoctoral Science Foundation: 2017M621156","The work described in this paper was financially supported by the Project funded by China Postdoctoral Science Foundation (No. 2017M621156).",,,,,,,,,,"Ding, Y., Qi, L., Li, Z.X., Mechanical calculation model for welded hollow spherical joint in spatial latticed structures (2011) Adv.

Traditional sensitivity-based updating methods cannot support updating based on static and dynamic measurement data at the same time. The finite element model is required in every optimization iteration which limits the efficiency greatly. A convenient but accurate Kriging surrogate model for updating of the finite element model of cable-stayed bridge is proposed. First, a simple cable-stayed bridge is used to verify the method and the updating results of Kriging model are compared with those using the response surface model. Results show that Kriging model has higher accuracy than the response surface model. Then the method is utilized to update the model of a long-span cable-stayed bridge in Hong Kong. The natural frequencies are extracted using various methods from the ambient data collected by the Wind and Structural Health Monitoring System installed on the bridge. The maximum deflection records at two specific locations in the load test form the updating objective function. Finally, the fatigue lives of the structure at two cross sections are calculated with the finite element models before and after updating considering the mean stress effect. Results are compared with those calculated from the strain gauge data for verification. © 2020 Techno-Press, Ltd.","Cable-stayed bridge; Fatigue life; Health monitoring; Mean stress effect; Model updating; Surrogate model","Buffeting; Cable stayed bridges; Cables; Interpolation; Iterative methods; Load testing; Strain gages; Structural health monitoring; Surface properties; Uncertainty analysis; Finite element modelling; Finite-element model updating; Kriging surrogate model; Long span cable stayed bridges; Response surface modeling; Static and dynamic behaviours; Structural configurations; Structural health monitoring systems; Finite element method",,,,,"National Natural Science Foundation of China, NSFC: 51608162","The authors gratefully acknowledge the Highways Department of the Hong Kong Government for assistance received in producing this paper as well as permission of its publication.

The simulation includes a three dimensional transient and nonlinear sequentially coupled thermal and mechanical analyses in ANSYS commercial code using an element birth and death technique to model the addition of welding metal to the specimen. A typical fillet-welded joint is studied and the simulation results are compared with experimental data for a gas metal arc welding process. The effect of eight welding sequences on the magnitude and shape of distortion in the plate on six lines is investigated. Finally, it is found the significant features of occurred distortion for various welding sequences in which not only the magnitudes but also the deformed shapes of the welding distortion are obviously different. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.","distortion;

The uniqueness of the harvester lies in the fact that the energy of 2-D excitation is scavenged by a single piezoelectric stack transducer, which can reduce the loss of harvestable energy. The harvester is constructed by the integration of permanent magnets, position protection plates, and multistage force amplification frame. The input force and input displacement are restricted to guarantee the device's safety. The reported multistage force amplification frame with leverage mechanism and bridge-type amplifier enlarges the force acting on the piezoelectric stack, which further improves the power output. A linear guiding mechanism based on leaf flexure is applied to minimize the impact of input forces in other than moving directions. Through analytical modeling, the main architectural parameters of the device are determined. Simulation study with finite-element analysis is conducted to optimize the device parameters for achieving the largest force amplification ratio with a high safety factor. A prototype harvester is fabricated for experimental study. Results demonstrate the feasibility of the developed 2-D piezoelectric stack-based energy harvester. © 1986-2012 IEEE.","Compliant mechanism; energy harvester; force amplification frame; permanent magnets; piezoelectric stack","Compliant mechanisms; Energy harvesting; Mechanisms; Permanent magnets; Safety factor; Architectural parameters; Energy Harvester; Force amplification; Mechanical energies; Piezoelectric energy harvesters; Piezoelectric stack; Position protection; Simulation studies; Piezoelectricity",,,,,"National Natural Science Foundation of China, NSFC: 51575545; Universidade de Macau, UM: MYRG2018-00034-FST, MYRG2019-00133-FST; Fundo para o Desenvolvimento das Ciências e da Tecnologia, FDCT: 143/2016/A, 179/2017/A3","Manuscript received June 11, 2019; accepted November 25, 2019.

ANSYS nonlinear finite element analysis (FEA) software was employed to model RC beams which were validated using the data from an existing experimental study in the literature. Parameters considered were rod length and NSM rod material type under three prestressing levels 20, 30 and 40%. The influence of these parameters on the beams’ load carrying capacity, midspan displacement, ductility index, and failure mode were determined. The results showed that at higher levels of rod prestressing, cracking, yielding, and ultimate load capacities of the beam were improved. However, the displacement was decreased and consequently, the ductility index reduced as prestressing level increased. Furthermore, the Fe-SMA material was able to provide significant ductility. The optimum prestressing level could be identified based on the primary RC beams’ design criteria to either improve load or displacement capacity or both. © 2020","CFRP; Coupled CFRP-Fe-SMA; GFRP; Hybrid; Iron-Based Shape Memory Alloy (Fe-SMA); Prestressing; Shape Memory Alloy (SMA)","Bridge decks; Carbon fiber reinforced plastics; Concrete beams and girders; Ductility; Fiber reinforced plastics; Iron alloys; Polymers; Prestressing; Shape-memory alloy; Coupled CFRP-Fe-SMA; GFRP; Hybrid; Iron-based shape memory alloys; Shape memory alloys(SMA); Reinforced concrete; alloy; displacement; ductility; finite element method; iron; polymer; reinforced concrete; structural component",,,,,,,,,,,,,,,,"www.aslanfrp.com, Aslan FRP; Rezazadeh, M., Costa, I., Barros, J., Influence of prestress level on NSM CFRP laminates for the flexural strengthening of RC beams (2014) Compos Struct, 116, pp. 489-500; You, Y.C., Choi, K.S., Kim, J., An experimental investigation on flexural behavior of RC beams strengthened with prestressed CFRP strips using a durable anchorage system (2012) Compos B, 43, pp. 3026-3036; Hajihashemi, A., Mostofinejad, D., Azhari, M., Investigation of RC beams strengthened with prestressed NSM CFRP laminates (2011) J Compos Constr, 15 (6), pp. 887-895; Peng, H., Zhang, J., Cai, C.S., Liu, Y., An experimental study on reinforced concrete beams strengthened with prestressed near surface mounted CFRP strips (2014) Eng Struct, 79, pp. 222-233; Shahverdi, M., Czaderski, C., Annen, P., Motavalli, M., Strengthening of RC beams by iron-based shape memory alloy bars embedded in a shotcrete layer (2016) Eng Struct, 117, pp. 263-273; Kim, Y.J., Shi, C., Green, M.F., Ductility and cracking behavior of prestressed concrete beams strengthened with prestressed CFRP sheets (2008) J Compos Constr, 12 (3), pp. 274-283; Barros, J.A.O., (2009), Prestress technique for the flexural strengthening with NSM-CFRP strips.

However, currently available load resisting systems for rocking frames rely on sacrificial yielding components that accumulate damage during strong dynamic action. To address this shortcoming, this study proposes a novel thoroughly damage-avoidance solution by means of bracing elements with carefully controlled buckling behaviour. To this end, a proof-of-concept study is presented, whereby the elastic buckling response of buckling-enabled composite bracing (BECB) elements with circular-arc shaped cross-section is numerically investigated. Varying geometric properties are considered and validated against analytical approximations. Besides, a finite element study of a single-storey steel post-tensioned frame under static and dynamic actions is performed.

Beneath it is the subgrade which also has a considerable influence on the track support stiffness. Although quasi-static measurements of track stiffness are reasonably common, the dynamic stiffness at higher frequencies is required for noise and vibration modelling. Here, a distinction is made between the dynamic stiffness of the ballast layer itself and the dynamic support stiffness which includes the underlying ground. The dynamic transfer stiffness of a ballast layer is required for ground vibration and bridge noise predictions. Two different methods for measuring this are presented, one in the laboratory and the other in the field. The laboratory method is limited to a maximum frequency of about 600 Hz due to limitations of the test rig. The field measurement, which relies on identifying the wavespeed within the medium, gives results up to 2 kHz. These methods give broadly consistent results, with a stiffness per rail seat for a 300 mm thick ballast layer of approximately 300–500 MN/m, increasing in proportion to the square root of the preload, and a damping loss factor in the range 0.15–0.3. The corresponding Young's modulus is between 200 and 700 MPa, depending on the preload. The dynamic stiffness increases above about 300 Hz with a first peak due to standing wave effects occurring at about 700 Hz. The dynamic support stiffness beneath the sleeper, on the other hand, is required for rolling noise modelling. This has been measured using two methods: a direct method for frequencies 50–500 Hz and an indirect method based on a modal analysis of a sleeper embedded in the ballast. A clear shift in natural frequencies is seen which is associated with the support stiffness. This support stiffness is strongly frequency-dependent, with the value per rail seat increasing from about 100 to 200 MN/m at 100 Hz to 2000 MN/m at 1 kHz. The support damping corresponds to a loss factor of around 1 for frequencies above 200 Hz, or a damping coefficient of 100–200 kN/m per rail seat. This damping is due to the radiation of energy into the ground rather than internal losses in the ballast. It strongly affects the modal damping of the sleeper and thus its radiated noise. The dynamic support stiffness increases roughly in proportion to the cube root of the preload. Comparison with a finite element model indicates that the underlying ground is responsible for the support stiffness and damping at low frequencies. However, above about 500 Hz it is independent of the ground and is only affected by the ballast layer. The results from the finite element model imply behaviour similar to a viscous damper. The sleeper vibration obtained using either a viscous damping or a constant loss factor is similar. © 2019 Elsevier Ltd","Damping models; Dynamic stiffness; Ground vibration; Railway ballast; Rolling noise","Acoustic noise measurement; Ballast (railroad track); Damping; Elastic moduli; Modal analysis; Railroads; Rails; Stiffness; Damping model; Dynamic stiffness; Ground vibration; Railway ballasts; Rolling noise; Finite element method",,,,,"Engineering and Physical Sciences Research Council, EPSRC: EP/H044949/1, EP/M025276/1; University of Southampton","The work described here has been supported by the EPSRC under the programme grants EP/H044949/1 , ‘Railway Track for the 21 st Century (Track 21)’ and EP/M025276/1 , ‘The science and analytical tools to design long life, low noise railway track systems (Track to the Future)’.

This paper focuses on energy efficiency instead of nominal load efficiency and demonstrates that energy efficiency of Phase shifted full bridge can be improved by reducing the ZVS range slightly. This proposed design requires a transformer with low inductance. However there are practical limitations to how far the leakage inductance could be minimized with conventional transformers. Hence this paper highlights that planar transformers are necessary over conventional transformers for the proposed design in order to meet the desired low leakage inductance. Several planar winding strategies are studied to present their effects on leakage inductance and the associated parasitic capacitance to optimize the design for energy efficiency. The results show how compactness could be achieved along with efficiency improvements. Experimental results of PSFB and a comparison between the conventional and proposed planar transformer using finite element model (FEM) is presented. © 2020 IEEE.",,"Bridges; Capacitance; Energy efficiency;

The thin bridges closing the rotor slots saturate highly as a function of the rotor current. The impedance of the rotor bars also varies much as a function of the rotor current frequency. An extended dynamic model, which takes into account the slot-bridge saturation and the deep-bar effect, is developed. The model extensions can be plugged into a standard machine model and parametrized easily. The proposed model can be applied to time-domain simulations, real-time control, and identification. The model is validated by means of finite-element analysis and experiments using a four-pole 5.6-kW induction machine. The results show that the accuracy of the proposed model is superior to the standard model, particularly under transient excitation typically used in standstill self-commissioning tests of induction motor drives. © 2019 IEEE.","Closed rotor slots; deep-bar effect; dynamic model; induction motor; magnetic saturation; standstill identification","Dynamic models; Induction motors; Real time control; Saturation magnetization; Time domain analysis; Deep-bar effect; Induction machines; Induction motor drive; Rotor slots; The standard model; Three-phase induction machine; Time-domain simulations; Transient excitation; Electric machine theory",,,,,"ABB","Manuscript received May 3, 2019; revised September 27, 2019; accepted October 23, 2019.

The bridge structure is modelled as an Euler-Bernoulli beam and the train is modelled as a series of axles in the form of sprung-mass with an unknown weight. Since the bridge-vehicle system is time-variant, the finite element model updating procedure is used as a response-based method. The effect of model and measurement uncertainties on identificationresults is investigated. The efficiency of the reliability-based method is compared with the deterministic and traditional probabilistic methods. In addition, the effect of critical parameters such as damping, speed and mass ratio on the accuracy of the proposed method is also discussed. It is observed in numerical models that the reliability-based method is the most accurate method for simultaneous identification of railway bridges in the presence of uncertainty. In addition to the damage index (DI), which indicates the location and the extent of damaged elements, the proposed method provides the probability and reliability of identified damages (RI) as well as the extent of unknown moving loads accurately. © 2020, Korean Society of Civil Engineers.","Finite element model updating; Railway bridge; Reliability analysis; Simulation; Simultaneous identification","Damage detection; Numerical methods; Railroad bridges; Railroads; Reliability analysis; Uncertainty analysis; Bridge-vehicle systems; Euler Bernoulli beams; Finite-element model updating; Modeling and measurement; Railway bridges; Response-based method; Simulation; Simultaneous identification; Finite element method",,,,,,,,,,,,,,,,"Bicanic, N., Chen, H.P., Damage identification in framed structures using natural frequencies (1997) International Journal for Numerical Methods in Engineering, 40 (23), pp. 4451-4468; Cavalagli, N., Comanducci, G., Ubertini, F., Earthquake-induced damage detection in a monumental masonry bell-tower using long-term dynamic monitoring data (2018) Journal of Earthquake Engineering, 22, pp. 96-119; Choi, S.K., Grandhi, R., Canfield, R.A., (2006) Reliability-based structural design, , Springer Science & Business Media, Berlin, Germany; Choi, H.G., Thite, A.N., Thompson, D.J., Comparison of methods for parameter selection in Tikhonov regularization with application to inverse force determination (2007) Journal of Sound and Vibration, 304 (3-5), pp. 894-917; Chopra, A.K., (2012) Dynamics of structures: Theory and applications to earthquake engineering, , Prentice-Hall, Upper Saddle River, NJ, USA; Doebling, S.W., Farrar, C.R., Prime, M.B., Shevitz, D.W., (1996) Damage identification and health monitoring of structural and mechanical systems from changes in their vibration characteristics: A literature review.

This study proposes a dynamic analysis framework by integrating the wind–wave–bridge system with Bayesian regularized back propagation neural network, and then investigates stochastic response of a cross-sea cable-stayed bridge under extreme wind and wave parameters. The wind–wave–bridge system involving wind–bridge and wave–bridge interactions is constructed to calculate dynamic response of the bridge by Newmark-β method, considering stationary fluctuating wind fields and multidirectional random wave fields. To reduce the calculation cost, a Bayesian regularized back propagation neural network model is introduced, and the model evaluation is carried out to illustrate its accuracy and efficiency. After performing small-scale finite element analyses, the response statistics are obtained and later used as the known samples for training the neural network. The power spectrum analyses of the deterministic results are performed to investigate the contribution mechanism of the wind and wave. Finally, the correlation between the bridge response and the single wind–wave parameter is given by uncertainty analysis of the Bayesian regularized back propagation neural network model. The results show that the proposed framework is capable of capturing the nonlinear bridge response resulting from nonlinear wind and wave loads, which, however, is significant different from that under wind alone. The bridge response receives significant contribution from wind and waves relative to the vibration characteristic of the bridge at smaller wind and wave loads. The contribution from vibration characteristic of the bridge becomes significant at larger wind and wave loads. The uncertainty analyses illustrate the significant effects of four wind and wave parameters on girder, tower, and submerged structure. © The Author(s) 2019.","Bayesian regulation; cross-sea bridge; multiple factors;

Since FRP has lower elastic modulus compared to steel, the serviceability aspect of FRP reinforced concrete (FRP-RC) members should be particularly considered in the structural analysis and design. This study addresses the deformation analysis of FRP-RC flexural members with thorough consideration of the tension-stiffening phenomenon in post-cracking state. The approaches for analyzing the tension-stiffening flexural response of FRP-RC beams are presented. These include the use of empirical or theoretical models to compute effective flexural stiffness, the use of finite element method in conjunction with nonlinear constitutive material models, and the use of tensile stress block in combination with member analysis. Among them, the latter is a relatively simple analysis approach. Aiming for serviceability assessment of FRP-RC beams in structural engineering practice to circumvent sophisticated theoretical approaches and constitutive models, parametrized tensile stress block is derived based on tension stress fields computed from finite element analysis, and is proposed for use in member analysis for prediction of deflections. Four FRP-RC beam specimens tested in the literature are analyzed to verify the proposed tensile stress block. Close agreement between the experimental and analytical results is achieved, thereby endorsing the applicability and reliability of the proposed method. © 2019 The Authors","Deflection; Fibre-reinforced polymer; Finite element method; FRP reinforcement; Member analysis; Serviceability; Tensile stress block; Tension-stiffening","Bridge decks; Concrete beams and girders; Deflection (structures); Deformation; Fiber reinforced plastics; Finite element method; Polymers; Steel corrosion; Steel fibers; Tensile stress; Fibre reinforced polymers; FRP reinforcement; Member analysis; Serviceability; Tension stiffening; Reinforced concrete",,,,,"Lietuvos Mokslo Taryba; European Social Fund, ESF: 09.3.3-LMT-K-712-01-0145","This project has received funding from European Social Fund (Project No. 09.3.3-LMT-K-712-01-0145) under a grant agreement with the Research Council of Lithuania (LMTLT).","This project has received funding from European Social Fund (Project No. 09.3.3-LMT-K-712-01-0145 ) under a grant agreement with the Research Council of Lithuania (LMTLT).",,,,,,,,,"Abrishambaf, A., Barros, J.A.O., Cunha, V.M.C.F., Tensile stress–crack width law for steel fibre reinforced self-compacting concrete obtained from indirect (splitting) tensile tests (2015) Cem Concr Compos, 57, pp. 153-165; ACI Committee 318, Building Code Requirements for Structural Concrete and Commentary, ACI 318M-14 (2014), p. 473. , American Concrete Institute Michigan, USA; ACI Committee 440, Guide for the Design and Construction of Structural Concrete Reinforced with FRP Bars, ACI 440.1R-15 (2015), p. 44. , American Concrete Institute Michigan, USA; Achillides, Z., Bond Behaviour of FRP Bars in Concrete (1998), p. 355 pp.. , (Ph.D Thesis) University of Sheffield Sheffield, UK; Al-Sunna, R., Pilakoutas, K., Waldron, P., Al-Hadeed, T., Deflection of FRP reinforced concrete beams (2005) Proceedings, Fourth Middle East Symposium on Structural Composites for Infrastructure Applications, Alexandria, Egypt; Baena, M., Torres, L., Turon, A., Barris, C., Experimental study of bond behaviour between concrete and FRP bars using a pull-out test (2009) Compos B Eng, 40 (6), pp. 784-797; Baena, M., Torres, L., Turon, A., Miàs, C., Analysis of cracking behavior and tension stiffening in FRP reinforced concrete tensile elements (2013) Compos B, 45 (1), pp. 1360-1367; Bangash, M.Y.H., Manual of Numerical Methods in Concrete: Modelling and Applications Validated by Experimental and Site-Monitoring Data (2001), p. 918. , Thomas Telford London, U.K; Barros, J.A.O., Behavior of Fibre Reinforced Concrete.

The internal thermal boundary conditions can be simulated by inputting the convection heat transfer coefficient and the temperatures inside the cavities or by establishing air elements in the FEM. In order to analyze the influence of different simulation methods for the internal thermal boundary conditions on temperature distributions for concrete closed girder cross-sections, the temperature distributions on the cross-sections of a box girder, small box girders, and adjacent box girders were monitored, and the corresponding FEMs were implemented. By comparing the temperature data obtained from the field test and FEMs, the numerical hourly temperature curves calculated by using the measured temperatures inside the cavities provide the closest agreement with the measured results; however, the measurements of the temperatures on site are cost-and time-prohibitive. When there is a lack of measured temperatures inside the cavities, the numerical hourly temperature curves calculated by establishing air elements in the FEM provide the closest agreement. The influences of different simulation methods for the internal thermal boundary conditions on the highest hourly average effective temperatures and the trends of the vertical temperature gradients for concrete closed girder cross-sections were small. The FEM with air elements can be adopted to analyze the temperature distributions on concrete closed girder cross-sections under historically extreme temperature conditions. It can be predicted that the longitudinal thermal movement of concrete closed girders would be underestimated by considering variations in the one-year measured average effective temperature of the cross-sections or the Chinese-code-specified design effective temperature for the highway bridge structures, which are thus unconservative for engineering applications. The Chinese-code-specified design vertical temperature gradients are conservative for the bridge deck surface and unconservative for the bottom flange. © 2020 by the authors.","Air element; Average effective temperature; Concrete closed girder cross-section; Finite element simulation; Historically extreme temperature condition; Hourly temperature curve; Internal thermal boundary condition; Vertical temperature gradient",,,,,,"National Natural Science Foundation of China, NSFC: 51508103, 51578161","This research was funded by the National Natural Science Foundation of China grant number 51508103 and the National Natural Science Foundation of China grant number 51578161.

There are many pre-1950s bridges still in use today. In recent years, great resources have been devoted to the restoration of historical timber bridges to preserve and pass them to the next generations. Because wood is an orthotropic, hygroscopic, and biodegradable material, structural behavior of timber bridges should be evaluated numerically using finite-element (FE) methods before and after restoration and systematic controlled in situ, or nondestructive experimental measurements should be made. This paper considers a historical timber bridge, using numerical modeling and modal testing to determine the structural modal parameters and FE model updating for approximation of numerical results to experimental results. As an application, the Buzluplnar historical timber bridge located in the Çayeli District of Rize, Turkey, is selected. The historical Buzluplnar Bridge was built in the middle of the nineteenth century, restored at different times for different reasons such as fire and wind effects, among others, and restored in 2014-2017. The FE model of Buzluplnar Bridge was formed using commercially available software to detect the initial modal parameters referenced on relief and restoration drawings. The orthotropic material properties are selected according to the laboratory material tests. Results of nondestructive experimental measurements, ambient vibration-based system identification was obtained using the enhanced frequency domain decomposition (EFDD) method (frequency domain) and stochastic subspace identification (SSI) method (time domain). The frequency values and mode shapes obtained by the FE model and experimental measurements are compared. According to these results, six natural frequencies are obtained between 2.0 and 20.0 Hz. Although the mode shapes are compatible with each other, there is a 34.55% difference between the frequency values. In order to reduce the differences, the FE model of the historical timber bridge is updated with a manual update method. Thanks to the model updating, the maximum differences are decreased to below 1% except the fourth mode. To evaluate the influence of FE model update, time-history analyses are applied, and internal forces and displacements are presented. © 2019 American Society of Civil Engineers.","Experimental modal analysis; Finite-element method; Historical timber bridge; Modal parameters; Model updating","Bridge components; Composite beams and girders; Domain decomposition methods; Electric measuring bridges; Frequency domain analysis; Modal analysis; Nondestructive examination; Restoration; Stochastic systems; Timber; Time domain analysis; Wind effects; Wooden bridges; Enhanced frequency domain decompositions; Experimental modal analysis; Finite-element model updating; Modal parameters; Model updating; Orthotropic material properties; Stochastic subspace identification; Timber bridge; Finite element method",,,,,,,,,,,,,,,,"Altunlşlk, A.C., Adanur, S., Genç, A.F., Günaydln, M., Okur, F.Y., An investigation of the seismic behaviour of an ancient masonry bastion using non-destructive and numerical methods (2017) Exp.

The common methods of predicting the train-induced vibrations in large-scale IBBS are implemented in the time domain and can have prohibitively long computation times. This paper presents a frequency domain model for the vibration analysis of large-scale IBBS, with the aim of reducing the computation time while retaining sufficient accuracy. The model consists of three coupled subsystems: train, track, and IBBS. The train and track subsystems are investigated analytically, and the IBBS subsystem is solved numerically using a finite element method. The receptance technique is introduced to obtain the wheel/rail force. The force transmitted to the floor slab is treated as the vibration source of the IBBS subsystem. The simulated vibration levels in the IBBS subsystem are compared with those obtained from in situ measurements, and a good agreement is observed in terms of both magnitude and frequency dependence. The vibration responses of the IBBS subsystem at different locations of the track floor and the waiting floor are compared, and the influence of the track position is investigated. Finally, a parametric analysis is conducted with the aim of formulating anti-vibration measures, in which the carbody acceleration, rail displacement, and ballast acceleration are considered as key indicators. The force transmission, vibration transmission and IBBS vibrations are also investigated. The results indicate that using a ballast mat and enlarging the column cross-section are the two most promising measures for reducing the vibration levels. © IMechE 2019.","integrated building–bridge structure; modelling; Railway station; vibration; vibration isolation","Ballast (railroad track); Floors; Frequency domain analysis; Models; Railroad stations; Railroad transportation; Railroads; Rails; Time domain analysis; Bridge structures; Frequency domain model; High-speed railway stations; Integrated buildings; Railway stations; vibration; Vibration isolations; Vibration transmission; Vibration analysis",,,,,"National Natural Science Foundation of China, NSFC: 51778534, 51878565",,,,,,,,,,,"Lombaert, G., Degrande, G., François, S., Ground-borne vibration due to railway traffic: A review of excitation mechanisms, prediction methods and mitigation measures Proceedings of the 11Th International Workshop on Railway Noise, 126, pp. 253-287. , Nielsen J, Anderson, D, Gautier PE, et al, Uddevalla, Sweden, 9–13 September 2013.

Specifically, an elastic-damage traction-separation model for ITZ is constructed, and an anisotropic plastic-damage model distinguishing the strength-difference under tension and compression for mortar matrix is proposed as well. In this anisotropic plastic-damage model, the weakening effect of micro voids is reflected by introducing initial isotropic damage, the distinct characteristic of tension and compression which described by decomposing damage tensor into tensile and compressive components, and the plastic yield surface which established on the effective stress space. Furthermore, by tracking the damage evolution of concrete specimens suffering uniaxial tension and compression, the effects of imperfect status of ITZ and volume fraction of initial voids on the concrete mechanical properties are investigated. © 2020 Tech Science Press.

To that end, an associated analysis concept is proposed in this paper. The applied smeared crack model allows one to realistically reproduce characteristic damage patterns observed at existing bridge structures of this type. By using the proposed analysis concept, load-bearing reserves may be revealed and possible causes for existing damage may be identified. The concept includes appropriate failure criteria and corresponding safety margins. The latter approximately conform to valid design codes, but also account for the specifics of nonlinear analyses. In parametric studies, the objectivity of the analysis results and influences of different material parameters on the load-bearing behavior were investigated. Furthermore, two examples of the safety evaluation of existing masonry arch bridges are presented. In both cases, observed damage patterns could be reproduced in the numerical simulations. Destructive load tests at a disused bridge provided an additional opportunity to validate the proposed analysis concept. © The Author(s) 2019.","arch bridge; finite elements; Masonry; safety evaluation; smeared cracking","Arch bridges; Arches; Load testing; Masonry bridges; Masonry construction; Masonry materials; Nonlinear analysis; Masonry; Masonry arch bridges; Material parameter; Non-linear finite-element analysis; Nonlinear finite element simulation; Safety evaluations; Smeared crack model; Smeared crackings; Finite element method",,,,,,,,,,,,,,,,"Audenaert, A., Fanning, P., Sobczak, L., 2-D analysis of arch bridges using an elasto-plastic material model (2008) Engineering Structures, 30 (3), pp. 845-855; Bretschneider, N., Franck, S., Slowik, V., Load tests of a masonry bridge: Nonlinear finite element simulations of the load tests (2018) Mauerwerk-Kalender 2018, pp. 139-168. , Brücken im Bestand.

In evaluating the reliability of bridge, the load-resistance model has been used to express the bridge failure functions. Calculating the RI requires the definition of loads effects on the structure and structure resistance. The load and resistance implicit functions are evaluated by stochastic finite element method and the Monte Carlo method has been used for laboratory simulation. The sampling method is the Latin hypercube sampling. The innovations in this paper is to use the functions dependent on parameters, modulus of elasticity, Poisson ratio, density of materials, and traffic load of bridge deck. The number of random parameters is 19. These random parameters are defined by the Log-normal distribution function. In this paper, the reliability status of bridge is investigated in the ultimate limit state under gravitational loading. The constitutive law of the bridge material is considered to be linear elastic. Three types of compressive, tensile, and allowable deflection are considered as limit states of the present research. The case study of the Pole Kheshti Langroud HMAB showed that the required safety is not provided for the ultimate limit state and the bridge is at risk of failure. The RI of bridge in the tensile limit state is lower than the target RI. The sensitivity analysis of random variables of the load and resistance implicit functions to the deflection and tensile responses is investigated, and random parameters with more impact are specified. In the stress limit state and deflection limit state, the modulus of elasticity and weight per unit volume of the sidewalls have the greatest impact on safety, respectively. © 2019, Springer Nature Switzerland AG.","Deterministic finite element (DFE); Epistemic uncertainty; Monte Carlo; Random variable (RV); Sensitivity analysis (SA); Stochastic finite element (SFE)",,,,,,,,,,,,,,,,,"Altunışık, A.C., Kanbur, B., Genç, A.F., The effect of arch geometry on the structural behavior of masonry bridges (2015) Smart Struct Syst, 16 (6), pp. 1069-1089; da Silva Brandão, F., Diógenes, A., Fernandes, J., Mesquita, E., Betti, M., Seismic behavior assessment of a Brazilian heritage construction (2018) Frattura ed Integrità Strutturale, 12 (45), pp. 14-32; Fathi, A., Sadeghi, A., Emami Azadi, M.R., Hoveidaie, N., Assessing seismic behavior of a masonry historic building considering soil–foundation–structure interaction (case study of Arge-Tabriz) (2019) Int J Archit Herit; Güllü, H., Jaf, H.S., Full 3D nonlinear time history analysis of dynamic soil–structure interaction for a historical masonry arch bridge (2016) Environ Earth Sci, 75 (21), p. 1421; Hradil, P., Žák, J., Novák, D., Lavický, M., Stochastic analysis of historical masonry structures (2001) Historical Constructions.

The material properties are assumed to vary longitudinally. The variation is described by a polynomial. Secondary deformations, resulting from the angle of twist, are considered. The transfer matrix method serves as the analysis tool. The transfer relations are derived and used for establishing finite element equations for twisted FGM beams in local coordinate systems. The warping part of the first derivative of the twist angle, caused by the bimoment, is considered as an additional degree of freedom at the nodes of the beam elements. The numerical investigation is performed with or without consideration of the Secondary Torsional Moment Deformation Effect (STMDE). It is focused on elastostatic analysis of straight cantilever FGM beams with doubly symmetric open as well as closed cross-sections. The influence of the longitudinal variation of the material properties and of the secondary torsion moment on the deformation and stress state is investigated. The results are compared with the ones obtained by a very fine mesh of standard solid and shell as well as warping beam finite elements. © 2019 Elsevier Ltd","Finite element method; Functionally Graded Material beams; Longitudinally varying material properties; Non-uniform torsion; Secondary torsion moment deformation effect","Beams and girders; Box girder bridges; Deformation; Degrees of freedom (mechanics); Finite element method; Functionally graded materials; Thin walled structures; Torsional stress; Deformation effects; Finite element equations; Functionally graded material (FGM); Local coordinate system; Longitudinal variations; Non-uniform; Numerical investigations; Secondary torsional moment deformation effects; Transfer matrix method; composite; deformation; finite element method; stress field; structural component; torsion",,,,,"1/0102/18, No.","The authors gratefully acknowledge financial support by the Slovak Grant Agency of the project VEGA No. 1/0102/18 .

Experiments in compression were conducted in order to understand the failure modes including global and local buckling, load-bearing capacities, load-displacement curves and load-strain responses. Accordingly the effects of different connection methods and different spacing values between the SHS sections were clarified. Sudden debonding failure between GFRP panels and inner SHS columns was found on adhesively bonded specimens; while mechanically bolted specimens showed evident lateral deformation and progressive failure until the ultimate junction separation failure on the GFRP SHS columns. Local buckling was found on GFRP thin-walled panels of specimens with a larger spacing between the two SHS sections. Finite element analysis and analytical modelling were performed to estimate the load-displacement curves and the critical stress for the local buckling on GFRP thin-walled panels, where consistent agreements with experimental results were received. © 2019 Elsevier Ltd","Buckling; Compression; Glass fibre reinforced polymer; Sandwich structures; Square hollow sections; Thin-walled panels","Adhesives; Bridge decks; Buckling; Compaction; Fiber reinforced plastics; Glass bonding; Glass fibers; Reinforcement; Sandwich structures; Glass fibre reinforced polymers; Global and local buckling; Lateral deformation; Load-bearing capacity; Load-displacement curve; Progressive failure; Square hollow sections; Thin-walled panels; Thin walled structures",,,,,"Australian Research Council, ARC: DP180102208, IC150100023; National Natural Science Foundation of China, NSFC: 51778286","The authors acknowledge supports from the ARC Training Centre for Advanced Manufacturing of Prefabricated Housing (IC150100023) and the ARC Discovery project (DP180102208).

This study proposed a novel acoustic optimization method for declining the structure-borne noise in viaduct-like structures by separating the acoustic contribution of each structural component in the measured acoustic field. The structural vibration and related acoustic sourcing, propagation, and radiation characteristics for the viaduct box girder under passing vehicle loading are studied by incorporating Finite Element Method (FEM) with Modal Acoustic Vector (MAV) analysis. Based on the Modal Acoustic Transfer Vector (MATV), the structural vibration mode that contributes maximum to the structure-borne noise shall be hereinafter filtered for the acoustic radiation. With vibration mode shapes, the locations of maximum amplitudes for being ribbed to mitigate the structure-borne noise are then obtained, and the structure-borne noise mitigation performance shall be eventually analyzed regarding to the ribbing conduction. The results demonstrate that the structural vibration and structure-borne noise of the viaduct box girder mainly occupy both in the range within 100 Hz, and the dominant frequency bands both are [31.5, 80] Hz. The peak frequency for the structure-borne noise of the viaduct box girder is mainly caused by 16th and 62th vibration modes; these two mode shapes mainly reflect the local vibration of the wing plate and top plate. By introducing web plate at the maximum amplitude of main mode shapes that contribute most to the acoustic modal contribution factors, the acoustic pressure peaks at the field-testing points are hereinafter obviously declined, this implies that the structure-borne noise mitigation performance is relatively promising for the viaduct.

This is because these parts are very large in size and the crack size is very small, i.e. in microns. Hence, there is an important need to locate the crack and to find its severity before it starts to propagate and also to detect these parameters by on-site non-destructive testing methods. This paper aims to develop and test the methodology to locate an unknown single open crack in steel cantilever beam along with its severity. Design/methodology/approach: This study covers analytical, numerical and experimental analysis for healthy and cracked beams. Vibration-based approach and finite element analysis (FEA) approach is used for analytical and numerical study respectively. Own designed and dedicated experimental set-up is used for testing purpose along with fast fourier transform analyzer. An anti-resonance technique is used to locate and to find the severity of unknown crack. The statistical approach helps to validate the results. Findings: The comparison of the natural frequency of healthy and cracked steel cantilever beam shows that the crack in the beam reduces its natural frequency. The accuracy of results is achieved by finding actual density and Young's modulus of steel specimen under consideration. It is helpful to verify the health of the non-cracked beam by applying dye testing. The study of natural frequency and anti-resonance gives the location of crack and its depth also. The FEA approach proved to be an important tool for numerical analysis of cracked beam. Research limitations/implications: The research is limited to steel material and surface cracks only. Practical implications: Practically, this study highlights how to locate a surface crack in steel beam along with its depth, i.e. severity with great accuracy. Identification of the factors such as location and depth of a crack provide the severity of damage in airplane wings, turbine blades, bridges and many more, and thereby, it helps in safety at working vicinity. Social implications: The identification and solutions of current research helps to predict the operational life of machine elements such as airplane wings, turbine blades, bridges and many more, and thereby, it helps in the safety of people in working vicinity of such structures. Originality/value: The work presented, is based on original research and experimentation. This work is valued contribution in the field of methodologies applied for fault detection in structures and also determining its correctness by numerical and experimental work. © 2019, Emerald Publishing Limited.","Antiresonance; Crack; FFT analyzer; Finite element analysis; Steel beam; Vibration","Aircraft; Cantilever beams; Damage detection; Elastic moduli; Fast Fourier transforms; Fault detection; Finite element method; Nanocantilevers; Natural frequencies; Nondestructive examination; Occupational risks; Steel beams and girders; Steel research; Supersonic aerodynamics; Surface defects; Turbine components; Turbomachine blades; Vibration analysis; Wings; Anti-resonance; Design/methodology/approach; Fast Fourier transform analyzers; FFT analyzers; Nondestructive testing method; Numerical and experimental analysis; Steel beams; Vibration; Cracks",,,,,,"The author is greatly thankful to Nath Wire Cut Pvt.

This consideration is related to the fact that a structural system subjected to cyclic loadings may suffer from plastic collapse even when the loading magnitude is less than the instantaneous collapse load of single excursion. This paper first evaluates the shakedown limit state of a box girder model with and without the consideration of buckling. Nonlinear finite element analyses are also performed to investigate the structural behaviours of a case study model under six different cyclic loading protocols. The rationality of a shakedown limit state is discussed and an energy-based characterisation of limit state is suggested. The study shows that, whilst the use of shakedown limit state assessment may be overly conservative, the safety margin based on an ultimate limit state approach might be considerably reduced. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.","cyclic loading; ductile collapse; Shakedown limit state; ship hull girder; ultimate strength","Beams and girders; Box girder bridges; Cyclic loads; Hulls (ship); ductile collapse; Longitudinal strength; Non-linear finite-element analysis; Shakedown limit; Ship hull girder; Structural behaviour; Ultimate limit state; Ultimate strength; Loading",,,,,,,,,,,,,,,,"(2000), Ultimate Strength.

Seawater dry-wet cycles test was conducted on 20 NRBs and 63 rubber sheets for 60 days to investigate the influence of seawater dry-wet cycles on basic NRB performance. The change laws that govern the NRBs’ horizontal and vertical stiffness were obtained via seawater dry-wet cycles test. In addition, the proposed constitutive parameters of the rubber material were used to establish a finite-element model of the NRBs to simulate and analyze the bearings’ performance and time-varying law. The test results were then compared with the fitted and simulated results. Finally, the performance deterioration law of the NRBs was predicted over a 120-year lifespan based on the extrapolation of the 60-day test results, and the finite element analysis of the performance for NRB within 120-year service life was done to verify the reliable of the prediction result. The 60 days test results show that the NRBs’ horizontal and vertical stiffness increased by 23% and 7%, respectively, after test for 60 days, and horizontal and vertical stiffness increased linearly as the seawater dry-wet cycles test time increased.

This involves the solution of the incompressible Stokes equations coupled to an advection diffusion equation for the temperature, a Boussinesq approximation that governs the dependence of the density on the temperature, and an advection equation for a marker indicating two initial (constant) density states, that are passively advected in the underlying flow field. The Volume-of-Fluid method in ASPECT is fully parallelized and fully integrated with ASPECT's adaptive mesh refinement algorithm. We present the results of several interface tracking benchmarks in order to demonstrate the accuracy of the method, as well as the results of several benchmarks commonly used in the computational mantle convection community. Finally, we present the results of computations with and without adaptive mesh refinement of a model problem involving thermochemical convection in a computationally stratified fluid designed to provide insight into how thermal plumes, that eventually reach the Earth's surface as ocean island basalts, originate at structures near the core-mantle boundary known as Large Low Shear wave Velocity Provinces or “LLSVPs”. LLSVPs are structures in parts of the lowermost portion of the Earth's mantle, characterized by slow shear wave velocities and higher density than the surrounding mantle, which were discovered by seismic tomography of the deep Earth. © 2019 Elsevier Ltd","Adaptive mesh refinement; Compositionally stratified fluid; Large low shear wave velocity provinces; Rayleigh Taylor Instability; Rayleigh–Bénard problem; Thermochemical convection; Volume-of-Fluid method","Acoustic wave velocity; Advection; Bridge piers; Computational fluid dynamics; Diffusion in liquids; Mesh generation; Open systems; Seismology; Shear flow; Shear waves; Slow wave structures; Wave propagation; Adaptive mesh refinement; Rayleigh; Rayleigh-Taylor instabilities; Shear wave velocity; Stratified fluid; Volume of fluid method; Finite element method",,,,,"0949446, 1550901; National Science Foundation, NSF: 1440811; Cryptobranchid Interest Group, CIG","This work was supported by the National Science Foundation ’s (NSF) SI2-SSE Program under Award number 1440811 .

Moreover, PMs ending through stator yoke cause serious issues of flux leakages which deteriorate electromagnetic performance. In order to reduce PM usage and suppress flux leakage, Consequent Pole SFPMM (CPSFPMM) is developed that successfully suppress flux leakage and reduce PMs volume effectively. Moreover, Finite Element Analysis (FEA) is accomplished utilizing commercially available FEA package JMAG designer v.18.1 for performance evaluation of six different topologies of SFPMM and CPSFPMM with E-Core and C-Core. Various key performance indicators such as open-circuit flux linkage, cogging torque, torque ripples, Total Harmonic distortion (THD), electromagnetic torque and PM cost and weight are analyzed and compared. Based on Finite Element (FE) analysis developed CPSFPMM with E-Core and C-Core successfully suppress PMs leakages form stator and reduced PMs volume by 22.98% and PM cost by 22.49%. Thus, reduces overall machine cost and weight. Moreover, the proposed designs have successfully reduced cogging torque, torque ripples, THD, and improve torque capability under higher current density. © 2019 IEEE.","Consequent Pole; Finite Element Analysis; Flux Barriers; Flux Bridges; Flux switching machines; Permanent Magnet","Benchmarking; Cost reduction; Finite element method; Permanent magnets; Rare earths; Stators; Torque; Consequent-pole; Electromagnetic performance; Flux barrier; Flux-switching; Key performance indicators; Permanent-magnet machine; Rare earth permanent magnet; Total harmonic distortion (THD); Cost benefit analysis",,,,,,,,,,,,,,,,"Ullah, N., Khan, F., Ullah, W., Basit, A., Umair, M., Khattak, Z., Analytical modelling of open-circuit flux linkage, cogging torque and electromagnetic torque for design of switched flux permanent magnet machine (2018) Journal of Magnetics, 23 (2), pp. 253-266; Ullah, N., Khan, F., Ullah, W., Umair, M., Khattak, Z., Magnetic equivalent circuit models using global reluctance networks methodology for design of permanent magnet flux switching machine (2018) 2018 15th International Bhurban Conference on Applied Sciences and Technology (IBCAST), pp. 397-404. , Islamabad; Jusoh, L.I., Sulaiman, E., Kumar, R., Bahrim, F.S., Design and performance of 8S1ot-12Pole permanent magnet flux switching machines for electric bicycle application (2017) International Journal of Power Electronics and Drive Systems (IJPEDS), 8 (1), pp. 248-254; Shen, J.-X., Fei, W.Z., Permanent magnet flux switching machines-Topologies, analysis and optimization (2013) Proc.

In addition, the few engineers who carry out dynamic analysis do not usually consider the interaction between the bridge and vehicles. Thus, in this article, a simple methodology to consider the interaction between the bridge and vehicles in the dynamic analysis of bridges is proposed. The proposed method allows determining the dynamic response of road bridges due to the dynamic loads caused by vehicles traveling on rough pavement, taking into account the bridge-vehicle interaction. For illustration purposes, the proposed methodology is applied to a concrete bridge built on the Rio-Santos highway (Rio de Janeiro, Brazil). The bridge was modeled as a simply supported highway box girder bridge without balances divided into beam elements according to the FEM, the pavement-roughness profiles were obtained according to the ISO 8608 standard, four simplified models of vehicles were used, and the dynamic analysis was performed through the Newmark method. The results show that the proposed method is able to determine the dynamic response of the bridge, taking into account the bridge-vehicle interaction. Therefore, the proposed methodology can be recommended as an effective tool to improve bridge design. © 2019 American Society of Civil Engineers.","Dynamic response; Pavement roughness; Road bridges; Vehicle-bridge interaction","Box girder bridges; Dynamic loads; Dynamic response; Pavements; Steel bridges; Vehicles; Bridge-vehicle interaction; Effective tool; Equivalent static analysis; Newmark methods; Pavement roughness; Road bridge; Simply supported; Vehicle-bridge interaction; Highway bridges",,,,,"Coordenação de Aperfeiçoamento de Pessoal de Nível Superior, CAPES; Conselho Nacional de Desenvolvimento Científico e Tecnológico, CNPq","The authors acknowledge the financial support of CNPq and CAPES.",,,,,,,,,,"(2003) Technical Norm: Projeto e Execução de Pontes de Concreto Armado e Protendido, , ABNT (Associação Brasileira de Normas Técnicas).

The inherent variations in a bridge's constituent materials, its deterioration over time and other types of damage directly affect the structural response of these heritage structures. In order to characterise the structural components and behaviour of a masonry arch bridge in Korea, a series of full-scale experiments including dynamic measurements, non-destructive tests and advanced geomatics techniques were conducted. Three-dimensional (3D) models of Hongye-gyo Bridge were created using commercial finite-element (FE) software and various modifications were also made to enhance the computer model. Using experimental and numerical results obtained with advanced technologies, a rational definition of the material properties and structural geometry was simulated with a 3D FE model. It was found that, despite the complexity of masonry stone arch bridges, reasonable assumptions of material properties and the friction angle between the voussoir's interfaces enable a good prediction of a bridges' actual performance with a margin of 12%. © 2018 ICE Publishing: All rights reserved.",,"3D modeling; Arches; Deterioration; Masonry bridges; Masonry materials; Nondestructive examination; Constituent materials; Dynamic measurement; Full-scale experiment; Heritage structures; Masonry arch bridges; Non-destructive test; Structural component; Three-dimensional (3D) model; Arch bridges; bridge; damage; dynamic analysis; experimental study; finite element method; nondestructive testing; numerical model; software; structural response; Korea",,,,,"National Research Foundation of Korea, NRF","This research was supported by a grant (2016R1A2B4014186) from the National Research Foundation of Korea.",,,,,,,,,,"Altunisik, A.C., Bayraktar, A., Genc, A.F., Determination of the restoration effect on the structural behavior of masonry arch bridges (2015) Smart Structures and Systems, 16 (1), pp. 101-139; Altunisik, A.C., Kanbur, B., Genç, A.F., The effect of arch geometry on the structural behavior of masonry bridges (2015) Smart Structures and Systems, 16 (6), pp. 1069-1089; (2017) Ansys Academic Research, Release 17, , Ansys 0.

Starting from the analysis of a simply supported Euler–Bernoulli beam model subjected to moving loads, a three-dimensional multi-body (soil–abutment–bridge–ballast–sleeper–rail) model formulated in the time domain to study the vibrations induced due to the passage of moving concentrated loads was analysed using the direct finite element method of soil–structure interaction analysis. The high-speed train was considered to be a set of concentrated loads, the rail was modelled as a Euler–Bernoulli beam (frame element), and the sleepers, ballast, bridge, abutments and soil were modelled using eight-node solid (brick) elements. Layered soil stratum’s effects on the dynamic response of the bridge deck and variation of stresses were studied. From this study, it was observed that the direct method of FE analysis can be an effective tool to solve the complex dynamic soil–structure interaction problems. © 2018, Shiraz University.","3D continuum model; Dynamic soil–bridge interaction; Layered soil; Moving loads; Newmark-β integration",,,,,,,,,,,,,,,,,"Biondi, B., Muscolino, G., Sofi, A., A substructure approach for the dynamic analysis of train-track-bridge system (2005) Comput Struct, 83 (28-30), pp. 2271-2281; Cheng, Y.S., Au, F.T.K., Cheung, Y.K., Vibration of railway bridges under a moving train by using bridge-track-vehicle element (2001) Eng Struct, 23 (12), pp. 1597-1606; Chopra, A.K., (2008) Dynamics of structures theory and applications to earthquake engineering, , 3, Prentice Hall of India, New Delhi; Cook, R.D., Malkus, D.S., Plesha, M.E., Witt, R.J., (2004) Concepts and applications of finite element analysis, , 4, Willey, Hoboken; Delgado, R.M., Cruz, S., Modelling of railway bridge–vehicle interaction on high-speed tracks (1997) Comput Struct, 63 (3), pp. 511-523; Doménech, A., Museros, P., Influence of the vehicle model on the response of high-speed railway bridges at resonance.

The model can be implemented in commercial finite element software and allows performing inertial soil-structure interaction analyses of structures considering the coupled roto-translational, vertical and torsional behaviour of the soil-foundation system. Pile groups arranged in a square layout are considered; the soil profile is constituted by a homogeneous deformable soil layer overlying a bedrock where piles are socked for a fixed length. Formulas are calibrated with a nonlinear least square procedure, based on data provided by an extensive non-dimensional parametric analysis of the soil-foundation systems, performed with a Winkler's type model, previously developed by the authors, which assumes soil and piles to behave linearly. Firstly, the suitability of the adopted numerical tools in capturing the dynamic stiffness of end-bearing foundations is proven. Then, capabilities of the proposed formulas in estimating parameters of the best lumped systems are shown, and, for some case studies, comparisons of non-null terms of the impedance matrix obtained through the best lumped system, the one computed through the formulas, and the impedances resulting from the dynamic analyses, are presented. Finally, some applications of the proposed formulas in the framework of the seismic soil-structure interaction analysis of bridges are shown to demonstrate the capability of the adopted lumped system and the formula efficiency in assuring a reliable evaluation of the superstructure seismic response, with respect to that obtained from a more rigorous approach. © 2019 Elsevier Ltd","End-bearing pile groups; Foundation impedances; Inertial analysis; Lumped parameter model; Soil-structure interaction","Parameter estimation; Pile foundations; Piles; Seismology; Soil structure interactions; Soils; Stiffness; End-bearing piles; Estimating parameters; Finite element software; Frequency dependent; Inertial analysis; Lumped parameter modeling; Non-linear least squares; Parametric -analysis; Lumped parameter networks; dynamic analysis; finite element method; inertia; pile group; seismic response; soil-structure interaction; stiffness; torsion",,,,,,,,,,,,,,,,"Hassani, N., Bararnia, M., Amiri, G.G., Effect of soil-structure interaction on inelastic displacement ratios of degrading structures (2018) Soil Dyn Earthq Eng, 104, pp. 75-87; Ghandil, M., Behnamfar, F., Ductility demands of MRF structures on soft soils considering soil-structure interaction (2017) Soil Dyn Earthq Eng, 92, pp. 203-214; Stefanidou, S.P., Sextos, A.G., Kotsoglou, A.N., Lesgidis, N., Kappos, A.J., Soil-structure interaction effects in analysis of seismic fragility of bridges using an intensity-based ground motion selection procedure (2017) Eng Struct, 151, pp. 366-380; Behnamfar, F., Banizadeh, M., Effects of soil–structure interaction on distribution of seismic vulnerability in RC structures (2016) Soil Dyn Earthq Eng, 80, pp. 73-86; Anastasopoulos, I., Sakellariadis, L., Agalianos, A., Seismic analysis of motorway bridges accounting for key structural components and nonlinear soil-structure interaction (2015) Soil Dyn Earthq Eng, 78, pp. 127-141; Carbonari, S., Morici, M., Dezi, F., Gara, F., Leoni, G., Soil-structure interaction effects in single bridge piers founded on inclined pile groups (2017) Soil Dyn Earthq Eng, 92, pp. 52-67; Capatti, M.C., Tropeano, G., Morici, M., Carbonari, S., Dezi, F., Leoni, G., Implications of non-synchronous excitation induced by nonlinear site amplification and soil-structure interaction on the seismic response of multi-span bridges founded on piles (2017) Bull Earthq Eng, 15 (11), pp. 4963-4995; Carbonari, S., Dezi, F., Leoni, G., Non-linear seismic behaviour of wall-frame dual systems accounting for soil-structure interactions (2012) Earthq Eng Struct Dyn, 41 (12), pp. 1651-1672; Elgamal, A., Yan, L., Yang, Z., Conte, J.P., Three-dimensional seismic response of Humboldt Bay bridge-foundation-ground system (2008) J Struct Eng ASCE, 134 (7), pp. 1165-1176; Maheshwari, B.K., Truman, K.Z., El Naggar, M.H., Gould, P.L., Three-dimensional nonlinear analysis for seismic soil–pile-structure interaction (2004) Soil Dyn Earthq Eng, 24, pp. 343-356; Wolf, J.P., Dynamic soil-structure interaction (1985), Prentice-Hall, Inc.

The slabs were constructed at one third scale and strengthened with basalt fibre reinforced polymer (BFRP) or carbon fibre reinforced polymer (CFRP) bonded in place using the near surface mounted (NSM) technique. As the research was representative of existing floor slabs within reinforced concrete building frames, all test specimens were constructed with normal strength concrete (∼40 N/mm 2 ) and 0.15% steel reinforcement. One tenth of one percent fibre reinforced polymer (FRP) was used to strengthen samples which were compared with unstrengthened control specimens. The London University Structural Analysis System (LUSAS) finite element analysis software package was used to model all test samples using experimentally derived material test values. Experiments and NLFEA models were compared with the Queen's University Belfast (QUB) arching theory which showed that LUSAS was slightly more accurate than the QUB arching theory in predicting slab capacity. However, the QUB arching theory was found to be slightly more consistent in estimating slab capacities compared with LUSAS.

However, the strength and serviceability of this type of bridge can frequently be compromised by the reductions in efficiency of load transfer and shear resistance due to joint degradation at the shear keys. Because of its superior mechanical properties and improved durability, ultra-high performance concrete (UHPC) has been proposed as an alternative grout material to eliminate shear key degradation. In this project, a single-span adjacent box-girder bridge was instrumented and monitored to investigate the performance of the UHPC shear keys under truck loads. The parameters of primary importance to shear key performance were identified from the response data. A finite element (FE) model of the bridge was developed to evaluate the efficiency of the load transfer mechanism at the UHPC joints. The UHPC shear key and transverse shear reinforcement bars fully transferred the load through the joints due to high bond strength of UHPC. The maximum relative displacement for all load cases was 0.151 mm (0.00594 in.) insufficient to cause damage to the UHPC shear key interface. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.","adjacent box-girder; bridge connection; finite element model; load-transfer mechanism; Precast concrete bridge; ultra-high performance concrete","Beams and girders; Box girder bridges; Bridge decks; Concrete bridges; Durability; Efficiency; Finite element method; Mechanical properties; Precast concrete; Steel bridges; Box girder; Bridge connections; Field investigation; Load transfer mechanism; Maximum relative displacements; Shear resistances; Transverse shear; Ultra high performance concretes; High performance concrete",,,,,,,,,,,,,,,,"(2012) Bridge design specifications, , 6th ed, Washington, DC: Association of State Highway and Transportation Officials; (2016) ABAQUS software version 6.12-3, , Providence, RI: Dassault Systèmes Simulia; (2011), Building code requirements for structural concrete and commentary.

However, limited work has been done on their shear behavior. In this paper, the corrugated steel web (CSW) in horizontally curved girders (HCGs) is treated as an orthotropic cylindrical shallow shell, and the analytical formula for the elastic global shear buckling stress is deduced by the Galerkin method. Calculation tables for the global shear buckling coefficient for a four-edge simple support, for a four-edge fixed support, and for the two edges constrained by flanges fixed and the other two edges simply supported are given. Then, a parametric study based on a linear buckling analysis is performed to analyze the effect of the curvature radius and girder span on the shear buckling stress. Analytical and numerical results show that the difference of shear buckling stress of CSWs between curved girders and straight girders is small, so the shear design formulas for straight girders can be applied for curved girders. Finally, a series of tests were performed on three curved box girders with CSWs. Similar to CSWs in straight girders, the shear strain distributions of CSWs in HCGs are almost uniform along the direction of the web height and the principal strain direction angles are close to 45°. For the three specimens, CSWs carry about 76% of the shear force. In the destructive test, shear buckling after yielding occurred in all specimens which is in good agreement with the theoretical prediction, which means that the analytical formulas provide good predictions for the shear buckling stress of CSWs in HCGs and can be recommended for design purposes. © 2019 by the authors.","Corrugated steel webs; Experimental work; Finite element analysis; Galerkin method; Horizontally curved girder; Shear buckling stress",,,,,,"National Natural Science Foundation of China, NSFC: 51378106; China Scholarship Council, CSC","Funding: This research was funded by the National Natural Science Foundation of China, grant number 51378106 and the China Scholarship Council.

An example RC solid-slab bridge is proposed and analyzed using an elastoplastic two-dimensional FE model. The bridge abutment is supported on a strip foundation. A multistage numerical technique is used to simulate the construction of the bridge, backfilling process, and alternate cycles of expansion and contraction of the bridge. The earth pressures on the abutment and the changes in these pressures, as well as the internal forces in the abutment, due to the cyclic thermal changes are predicted for different bridge lengths. The bridge is analyzed for a number of temperature change ranges. A comparison between the results obtained and those due to the embedded abutment counterpart structure is held. The results of analyses have shown that the design earth pressures may be appreciably affected by the bridge length, design temperature change range, the number of temperature increase/decrease cycles, type of abutment (frame/embedded), and the stiffness of the backfill material. The findings of this study may be beneficial to the enhancement of the present design guidelines of integral abutment bridges (IABs). © 2019 American Society of Civil Engineers.","Earth pressure; Finite-element (FE) analysis; Integral frame abutment bridge; Nonlinear soil model; Temperature variations","Expansion; Finite element method; Pressure distribution; Retaining walls; Temperature distribution; Abutment bridges; Earth pressure; Expansion and contraction; Integral abutment bridge; Non-linear finite-element analysis; Nonlinear soils; Seasonal temperature variations; Temperature variation; Abutments (bridge)",,,,,,,,,,,,,,,,"(2012) LRFD Bridge Design Specifications., , AASHTO. 6th ed.

Lack of an appropriate design to resist the forces caused by unevenly distributed temperatures may be one of the main reasons for these failures. In design practice, only vertical temperature differences are accounted for in the design, and transverse temperature difference effects on curved bridges have been ignored. In order to achieve deeper understanding of temperature effects on curved concrete bridges with single-column piers, the authors studied solar radiation effects on a curved bridge, investigating the transverse and vertical temperature differences in the box girder using three-dimensional finite-element analysis. Then, the stresses and displacements of a curved bridge with different support arrangements were calculated and compared. The results show that the displacements and stresses caused by transverse temperature differences are comparable with those from vertical temperature differences in the curved box girder, which indicates that displacements and stresses are significantly underestimated by only considering vertical temperature differences for curved bridges. After comparing the stresses and displacements for different support layouts, it is concluded that the use of two pinned connected supports in the middle piers significantly reduces the vertical displacement by 46.2% under transverse temperature differences and by 55.6% under vertical temperature differences, whereas the thermal stresses do not vary with a change of support layouts. © 2019 American Society of Civil Engineers.","Curved bridge; Finite-element model; Maximum solar radiation; Support arrangements; Temperature difference","Concretes; Finite element method; Piers; Radiation effects; Solar radiation; Steel bridges; Temperature; Concrete box girder bridge; Curved bridge; Displacements and stress; Temperature differences; Three dimensional finite element analysis; Transverse temperature; Vertical displacements; Vertical temperature differences; Box girder bridges",,,,,"AHGS 2014-18; 2014H27; National Natural Science Foundation of China, NSFC: 11502100, 51108152","The authors are grateful for the joint support of the National Natural Science Foundation of China (Nos. 51108152 and 11502100), Project of the Science Research Program, Transportation Department of Zhejiang Province of China (2014H27), and Traffic Science and Technology Project of Anhui Province Traffic Holding Group Co.

Under the working condition, 8 tires and 2 outriggers support on the ground. The supporting load of outrigger is much bigger than the tire, because of the stiffness distribution. After about six months in service, cracks tend to appear in the sub frame of bridge inspection vehicle, near the connection area between sub frame and front outrigger. To identify the cause of the crack failure and propose an approach to improve the design, a practical method using finite element analysis (FEA) and tests is carried out. The FEA model is established by the test of supporting load, and 5 load scenarios are considered. FEA and corresponding stress test of original sub frame are used to analyze the cause of the cracking. Analysis results indicate that the stresses are concentrated in the sub frame at the area of crack failure. Then, a solution for improvement of the sub frame is proposed by FEA. As the crack occurs near the weld seam, the fatigue assessment of welded joint is more scientific for the welded structure, so the fatigue of welded structure is discussed. According to BS 7608, the process of fatigue life assessment is proposed. Dynamic stress test is implemented to acquire the stress spectrum. By use of the software Ncode, the fatigue of the sub frame is calculated. The results indicate that the improved sub frame is much better than the original in the expected fatigue life. The improved sub frame has been in service for more than 15 months and no cracks appear up to date. © 2019 Elsevier Ltd","Bridge inspection vehicle; Crack; Failure; FEA; Sub frame","Automobile frames; Bridges; Computer system recovery; Cracks; Finite element method; Inspection; Welding; Welds; Bridge inspection; Bridge maintenance; British Standards; Fatigue assessments; Fatigue life assessment; Months in services; Stiffness distributions; Sub-frame; Fatigue of materials",,,,,,"This work is supported by Xuzhou construction machinery group for the promotion of innovation and industrialized application.",,,,,,,,,,"Grbovic, A., Rasuo, B., FEM based fatigue crack growth predictions for spar of light aircraft under variable amplitude loading (2012) Eng.

Fundamental vibration period or frequency is a key parameter to provide adequate information pertinent to dynamic characteristics and performance assessment of a structure. This parameter enables to assess seismic demand of a structure. It is possible to find an empirical formulation related to reinforced concrete structures, masonry towers and slender masonry structures. Calculated natural vibration frequencies suggested by empirical formulation in the literatures has not suits in a high accuracy to the case of rest of the historical masonry bridges due to different construction techniques and wide variety of material properties. For the listed reasons, estimation of fundamental frequency gets harder. This paper aims to present an empirical formulation through Mean Square Error study to find ambient vibration frequency of historical masonry bridges by using a non-linear regression model. For this purpose, a series of data collected from literature especially focused on the finite element models of historical masonry bridges modelled in a full scale to get first global natural frequency, unit weight and elasticity modulus of used dominant material based on homogenization approach, length, height and width of the masonry bridge and main span length were considered to predict natural vibration frequency. An empirical formulation is proposed with 81% accuracy. Also, this study draw attention that this accuracy decreases to 35%, if the modulus of elasticity and unit weight are ignored.

The concept has been developed firstly by Prof. Per Tveit during his Ph.D. Several network arch bridges have been built around the world due to the advantage this type of bridge presents. However, Network arch bridges as to conventional arch bridges are sensitive to lateral displacement under vertical loads. In this study, lateral structural response of network arch bridges against traffic loads has been analyzed through extensive non-linear analyses. The structural response of the arch showed a relationship between the lateral displacement and applied stress. In addition, it is observed that lateral arch’s bracing changes the development of plastic hinges in the arch. © 2019 The authors.","Critical loads; Finite element analysis; Lateral deflection; Traffic loads","Arches; Computational methods; Earthquake engineering; Engineering geology; Finite element method; Geophysics; Structural dynamics; Applied stress; Critical load; Lateral deflection; Lateral displacements; Network arch bridges; Structural behaviour; Structural response; Traffic loads; Arch bridges",,,,,,,,,,,,,,,,"Tveit, P., The design of network arches (1966) The Structural Engineer, 44 (7), pp. 249-259; Tveit, P., Bogebruer med skrå krysstilte hengestenger (1959) Arch Bridges with Inclined Intersecting Hangers, , Norwegian.

The problem of testing materials above this number of cycles is that most testing equipment operates well below 150 Hz, making testing up to 1 billion (1E9) cycles or above is an impracticality. The recent developments of ultrasonic testing machines where frequencies can go as high as 20 kHz or above enabled tests to be extended to these ranges in just a few days. This is known as very high cycle fatigue (VHCF). On the other hand, critical components used in engineering applications are usually subjected to multi-axial loads, as is the case of the fuselage and wings of aircrafts which are subjected to biaxial states of stress. In this paper, VHCF cruciform test specimens purposely designed to develop orthogonal biaxial stresses with different biaxiality ratios will be analysed. The specimens are composed from Aluminium 6082-T651, a medium strength alloy used in many highly stressed engineering applications, including trusses, cranes, bridges and transportation. The specimens work as tuning forks with determined mode shapes at 20±0.5 kHz, where maximum principal stresses are developed at the centre of the specimen. Finite element analysis (FEA) is used to assess the dynamic behaviour of the specimens. The framework on how to design and manufacture cruciform specimens with different biaxiality ratios will be explained in a clear way so it can be used by other engineers in the field. © 2019 WIT Press","Biaxial Stresses; Cruciform Specimens; Ultrasonic Testing; Very High Cycle Fatigue",,,,,,,,,,,,,,,,,"Suryanarayana, C., (2011) Experimental Techniques in Materials and Mechanics, , CRC Press: Boca Raton; Anes, V., Montalvão, D., Ribeiro, A., Freitas, M., Fonte, M., Design and instrumentation of an ultrasonic fatigue testing machine (2011) Proceedings of the 5th International Conference on Very High Cycle Fatigue, , Berlin, Germany; Freitas, M., Anes, V., Montalvão, D., Reis, L., Ribeiro, A., Design and assembly of an ultrasonic fatigue testing machine (2011) Proceedings of the 28th Encuentro Del Grupo Español de Fractura (Anales de Mecânica de La Fractura), , Gijón, Spain; Wycisk, E., Siddique, S., Herzog, D., Walther, F., Emmelmann, C., Fatigue performance of laser additive manufactured Ti-6Al-4V in very high cycle fatigue regime up to 109 cycles (2015) Frontiers in Materials, 2. , https://doi.org/10.3389/fmats.2015.00072, article; Bathias, C., There is no infinite fatigue life in metallic materials (1999) Fatigue and Fracture of Engineering Materials and Structures, 22, pp. 559-566. , https://doi.org/10.1046/j.1460-2695.1999.00183.x; Pyttel, B., Schwerdt, D., Berger, C., Very high cycle fatigue - Is there a fatigue limit?

The proposed methodology extends the established simplified progressive collapse method, which is only capable of simulating the monotonic bending moment-curvature relationship. However, the actual hull girder collapse can involve multiple load cycles, such as that caused by a series of storm waves. During these load cycles, the onset of plasticity and local buckling can reduce the overall strength and stiffness of the hull girder. Hence, a cyclic progressive collapse method is proposed to predict the ship hull girder structural response under cyclic bending. This method follows the major assumptions and procedure embedded in the original Smith method with an extended capability to re-formulate the load-shortening curve of structural element under cyclic loading. The proposed methodology is applied to predict the cyclic bending responses of two box girder models. Nonlinear finite element analysis is performed as a validation. The present study shows the feasibility of the proposed cyclic progressive collapse method, but also suggests the need to develop an enhanced model to predict the cyclic behaviour of structural components. © 2019 Taylor & Francis Group, London.",,"Box girder bridges; Curve fitting; Cyclic loads; Forecasting; Ocean structures; Structural design; Moment-curvature relationship; Non-linear finite-element analysis; Progressive collapse; Ship hull girder; Strength and stiffness; Structural component; Structural elements; Structural response; Hulls (ship)",,,,,,,,,,,,,,,,"(2000) Ultimate Strength.

It consists of a planar spring, a magnetoelectric transducer with an annular magnetic circuit, and a coil assembly with a ferrite bobbin inside. Based on these, a nonlinear magnetic force between the ferrite bobbin and permanent magnet arrays can be generated when the relative displacement changes, which can broaden the operating frequency bandwidth of the harvester. The nonlinear magnetic force makes the harvester demonstrate some special dynamic behaviors including the inter-well and chaotic motions, which are performed by the finite element analysis. And, the experimental validations are also carried to verify the performance of the proposed harvester. The results show that the output power can reach 10 mW in a relatively wide operating frequency range with a 90 Ω resistance load under 1 g harmonic excitation. In addition, a real vehicle road's vibration signals from a highway bridge are acquired to estimate the practical energy harvesting performance of the harvester. The results show that the RMS output voltage and load power of the harvester can reach 3.16 V and 110.95 mW under 10× road spectrum excitations, respectively. © 2019 IOS Press and the authors.

This research shows the use of finite element method in order to analyze factors that have effect on the bearing capacity such as the changes in the soil properties C and Ø where C and Ø are the cohesion and the friction of angle of soil, respectively and changes in the geometry of model, angle of slope β and the ratio b/B where b is the distance between footing and the point on the crest slope and B is the footing width. The results show that the increase in the ratio value b/B leads to an increase in the bearing capacity and it reduces the vertical settlement. The closeness of the footing to the edge of the slope leads to a reduction in its bearing capacity, the values of the lateral stress and lateral settlement are small when the ratio value is b/B>2.5. The bearing capacity decreases and the vertical settlement increases with the increase of the value of the angle of slope β; the decrease in the bearing capacity becomes significant when the value of slope angle increases more than 25º. The increase in the friction angle has a higher effect than the one in the soil cohesion on the bearing and displacement.

Therefore, unlike the DFT system in general concrete tracks, the track support stiffness (TSS) of the DFT system on the YGB cannot be evaluated with only the displacement of the rail. The actual TSS of the DFT system supported by the flexible track girders was lower than that of the DFT system supported by the general substructure. For this reason, field measurements and a finite element analysis that reflects the actual operating speed of railroad vehicles on the YGB (i.e., Airport Railroad Express (AREX), nonstop Airport Railroad Express (AREX Express), and Korea Train Express (KTX)) were conducted in this study to determine the interactions between the rail and the track girder. The results indicated that the DFT system on the YGB is supported by track girders that exhibit relatively flexible behavior. As a result, the TSS is directly influenced by the bending stiffness of the track girder. © 2019 Jung-Youl Choi et al.",,"Beams and girders; Railroads; Stiffness; Bending stiffness; Concrete tracks; Field measurement; Flexible behaviors; Long span railway bridges; Operating speed; Railroad vehicles; Track-bridge interactions; Railroad bridges",,,,,,"0e present study was conducted with funding from the Airport Railroad Co., Ltd.

Structures of this type are commonly used as elements of composite floors and primary carrying girders in bridge structures. Two-dimensional models used to date did not enable analysis of all eigenmodes, specifically torsional, flexural horizontal, and distortional. A discrete computational model was developed in the convention of the rigid finite element method, the so-called RFEM model. It was assumed that the concrete slab and the steel I-section would be modelled separately. This approach realistically reflects the actual performance of the connection, comprising studs connecting the concrete slab and the steel section. The model was used to analyse two steel–concrete composite beams with different connector spacings. The paper presents the results of experiments conducted on the two composite beams. Their dynamic characteristics, including frequency and vibration modes, were determined with impulse response methods.

In the design of a steel fender, detailed finite element (FE) models are usually employed. However, detailed FE analysis involves complicated modeling and substantial computation time. This method is often not applicable, particularly during preliminary design iterations. For this reason, a simplified analytical method was developed in this paper with the aim to efficiently design steel fenders under vessel collisions. For primary individual members of steel fenders, the deformation mechanisms and models as well as participations during various collision scenarios were discussed in detail. By combining the contributions of primary members, a general analytical procedure was presented to rapidly estimate the force-deformation relationship of steel fenders under various bow impacts. For the fixed and floating steel fenders, several collision scenarios were simulated by FE models to verify the accuracy of the developed analytical method. The crushing resistances and energy dissipation capacities estimated by the developed analytical method were in good agreement with those obtained from the FE simulations. Based on the analytical method, an energy-based design approach was proposed for the efficient design of steel fenders. The developed design approach was demonstrated to be capable of predicting the crush depth and peak impact force of a steel fender with good accuracy. © 2020 Elsevier Ltd","FE simulations; Simplified analytical method; Steel fender; Vessel collision","Deformation; Energy dissipation; Analytical procedure; Collision scenarios; Crushing resistance; Deformation mechanism; Energy dissipation capacities; Energy-based design; Preliminary design; Simplified analytical methods; Fenders (boat); collision; deformation mechanism; design method; finite element method; steel; vessel",,,,,"National Natural Science Foundation of China, NSFC: 51978258; Natural Science Foundation of Hunan Province: 2020JJ4186; Science and Technology Department of Guangxi Zhuang Autonomous: AD19245058","This research is supported by the National Natural Science Foundation of China (Grant Number: 51978258), the National Natural Science Foundation of Hunan Province (Grant Number: 2020JJ4186) and the Science and Technology Base and Talent Special Project of Guangxi Zhuang Autonomous (Grant Number: AD19245058).","This research is supported by the National Natural Science Foundation of China (Grant Number: 51978258 ), the National Natural Science Foundation of Hunan Province (Grant Number: 2020JJ4186 ) and the Science and Technology Base and Talent Special Project of Guangxi Zhuang Autonomous (Grant Number: AD19245058 ).",,,,,,,,,"AASHTO, Guide specifications and commentary for vessel collision design of highway bridges (2009), second ed. ed Washington, D.C; van Manen, S.E., Frandsen, A.G., Ship Collision with Bridges, Review of Accidents (1998); Yan, B., Dai, G.L., Investigation and countermeasures of ship-bridge collision accidents in China in recent years.

In this paper, the model of a continuously welded rail and a bridge with longitudinal nonlinear stiffness has been considered. The detailed mechanics equation of the rail on the bridge and the embankment with longitudinal nonlinear stiffness has been presented using the finite element analysis. The validity of the presented model and the compiled program is illustrated. The influences of nonlinear stiffness, span number of the bridge, constant longitudinal restoring force, bridge bearing arrangement, and the span length of the bridge on the additional longitudinal stress and displacement of rails are investigated for multispan simply supported bridges. The results show that (1) the responses of rails for the nonlinear stiffness are less than those for the linear stiffness; (2) when the bridge span reaches a certain number, the maximum additional longitudinal stress and the displacement of the rail tend to be constant; (3) with the increase of the value of the constant longitudinal restoring stress, the maximum additional longitudinal stress and the displacement of the rail increase; (4) the maximum additional longitudinal stress of the rail on multispan simply supported bridges can be reduced by using alternate bearings on one pier; and (5) the maximum additional longitudinal stress and displacement of the rail increase with the increase of the span length of the bridge. © IMechE 2019.","continuously welded rail; finite element method; nonlinear stiffness; simply supported bridge; Thermal interaction","Bearings (machine parts); Nonlinear equations; Railroad tracks; Rails; Stiffness; Welded steel structures; Welding; Alternate bearing; Compiled programs; Continuously welded rails; Longitudinal stress; Mechanics equation; Non-linear stiffness; Simply supported bridge; Thermal interaction; Finite element method",,,,,"National Natural Science Foundation of China, NSFC;NNSF;NNSFC: 51578552, U1334203; National Basic Research Program of China (973 Program): 2017YFB1201204",,,,,,,,,,,"Frýba, L., Thermal interaction of long welded rails with railway bridges (1985) Rail Int, 16, pp. 5-24; Frýba, L., (1996) Dynamics of railway bridges, , London, Thomas Telford Ltd; Esveld, C., (2001) Modern railway track, , Turkey, MRT Production; Jiang, J.Z., Additional longitudinal forces in continuously welded rails and their transmission on railway bridges (1998) China Railw Sci, 19, pp. 67-75; Cai, C.-B., Calculation of additional longitudinal forces in continuously welded rails on supper-large bridges of high-speed railways (2003) J Southwest Jiaotong Univ, 38, pp. 609-614; Ruge, P., Birk, C., Longitudinal forces in continuously welded rails on bridge decks due to nonlinear track-bridge interaction (2007) Comput Struct, 85, pp. 458-475; Ruge, P., Widarda, D.R., Schmälzlin, G., Longitudinal track–bridge interaction due to sudden change of coupling interface (2009) Comput Struct, 87, pp. 47-58; Okelo, R., Olabimtan, A., Nonlinear rail-structure interaction analysis of an elevated skewed steel guideway (2010) J Bridge Eng, 16, pp. 392-399; Yan, B., Dai, G., Zhang, H., Beam–track interaction of high-speed railway bridge with ballast track (2012) J Central South Univ, 19. , 1447–1153; Zhang, J., Wu, D.J., Li, Q., Loading-history-based track–bridge interaction analysis with experimental fastener resistance (2015) Eng Struct, 83, pp. 62-73; Strauss, A., Karimi, S., Šomodíková, M., Monitoring based nonlinear system modeling of bridge–continuous welded rail interaction (2018) Eng Struct, 155, pp. 25-35; Strauss, A., Šomodíková, M., Lehký, D., Nonlinear finite element analysis of continuous welded rail-bridge interaction: monitoring-based calibration (2018) J Civil Eng Manage, 24, pp. 344-354; Yun, K.-M., Park, B.-H., Bae, H.-U., Suggestion for allowable additional compressive stress based on track conditions (2018) Proc IMechE, Part F: J Rail and Rapid Transit, 232, pp. 1309-1325; Yun, K.-M., Bae, H.-U., Moon, J.H., Quantification of ballasted track-bridge interaction behavior due to the temperature variation through field measurements (2019) NDT Int, 103, pp. 84-97; De Backer, H., Outtier, A., Ferdinande, B., Application limits for continuously welded rails on temporary bridge decks (2017) Proc IMechE, Part F: J Rail and Rapid Transit, 231, pp. 482-497; Zhang, J., Wu, D.J., Li, Q., Experimental and numerical investigation of track-bridge interaction for a long-span bridge (2019) Struct Eng Mech, 70, pp. 723-735; (2001) Track/bridge interaction, , Recommendations for calculations, Paris; (2012) Code for design of railway continuous welded rail, , Beijing, CNS","Xu, Q.-Y.; School of Civil Engineering, China; email: xuqingyuan1972@163.com",,,"SAGE Publications Ltd",,,,,09544097,,PMFTE,,"English","Proc Inst Mech Eng Part F J Rail Rapid Transit",Article,"Final","",Scopus,2-s2.0-85077429522

Unlike cable-supported bridges with fixed towers, floating cable-supported bridges show relatively large displacements and rotations under the same load because of floating towers; moreover, the difference in the support stiffness causes differences in the behavior of the superstructures. In addition, the risk of overturning is greater than in conventional floating offshore structures because the center of gravity of the tower is located above the buoyancy center of the floater. A floating cable-supported bridge in which the tether supports the floating main tower is directly influenced by the tether arrangement, which is very important for the stability of the entire structure. In this study, according to the inclined tether arrangement, the outer diameter of the floater, and the buoyancy vertical load ratio (BVR), the static behavioral characteristics of the long-span cable-stayed bridges with floating tower are evaluated through nonlinear finite-element analysis. When the intersection of the tension line of the tether and a pivot point of the tower coincide, the tethers can no longer resist the tower’s rotation. For this reason, a large displacement occurs to equilibrate the structure, and further increases as it approaches the specific slope, even if it is not exactly the specific tether slope. The analytical model of this study indicates that, in terms of increasing the rotational stiffness of the main tower, it is advantageous to increase the floater diameter until a BVR of 1.8 is reached and to increase the axial stiffness of the tether from a BVR of 2.0 or higher. © 2020 by the authors.

The stress distribution due to flexure and shear of corrugated girders is different from that of the flat girders. Generally, due to the accordion effect, it is assumed that the web contribution is negligible to the bending moment resistance. Further, the use of slender flanges poses stability problems that require investigation. The current study evaluates the adverse effect of slender flange buckling on the moment of resistance of the corrugated web girders through the stability and strength analysis of the steel I-girders with corrugated webs. Extensive parametric studies on buckling co-efficient and moment capacities are carried out using a validated numerical model to develop a better understanding of the flexural capacities of slender (Class 4) cross-section corrugated girders. Also, various design models proposed over three decades from the literature are compared. Based on numerical results, an empirical equation is presented for the determination of the ultimate moment of resistance of slender flanges for corrugated girders. © 2020 Institution of Structural Engineers","Corrugated web; FEM analysis; Flange buckling; Flexural capacity; Nonlinear behaviour",,,,,,,,,,,,,,,,,"(2005), EN 1993-1-5: Eurocode3.

Not to mention, the evaluation of scour mechanism sheds light on pile foundation design and helps to prevent scour induced structural deficiencies. Thus, the scouring mechanism around bridge pile foundations should be extensively evaluated in order to predict the bridge safety under critical multi-hazard environment. In this study, the local scour mechanism around bridge piles was appraised considering discrete element methods (p-y curves) in order to reflect the nonlinear nature of soil structure interaction (SSI). Following that, bridge seismic behavior and relevant failure mechanism was evaluated with regard to nonlinear time history analyses (THA). In the conducted research, river crossing 7 – span Boğaçay Bridge located in Antalya, Turkey was selected as the case study. After SAP2000 finite element modeling (FEM), the bridge was exposed to twelve incremental scour depths up to six meters at all piers and was subject to subsequent seismic effects as concordant to the site that mimics a probable earthquake occurs after scouring regarding the Turkish Earthquake Code (TEC-2018). The modal responses indicated a simultaneous increase in natural periods with augmenting scour depth. In the analyses, the influence of scouring on pier displacement demands, pier accelerations and the internal forces at piers and piles were investigated. The analysis results indicated a significant increase in pier displacement demands with increasing scour depth especially in the transverse direction of the bridge. Further, due to the migration and spreading of plastic hinging from piers to piles due to scouring, the internal forces that were resisted by the strong axis of the pier columns decreased significantly. This fact led to the increase in pile bending moments and rotations in both orthogonal directions of the bridge. Thus, it was concluded that the probable multi-hazard effects of scouring and earthquake in river crossing bridges should be considered in bridge substructure design. © 2020","Concrete bridge; FEM; Nonlinear SSI; Nonlinear THA; Scour","Bridge piers; Concretes; Earthquakes; Hazards; Piers; Pile foundations; Piles; Scour; Soil structure interactions; Structural design; Bridge infrastructure; Bridge substructures; Displacement demand; Failure mechanism; Nonlinear nature; Nonlinear time history analysis; Orthogonal directions; Pile foundation design; Failure (mechanical)",,,,,"FYL-2018-3407","This work was supported by the Akdeniz University Scientific Research Project (AU-BAP) Project No: FYL-2018-3407.",,,,,,,,,,"AASHTO, L.R.F.D., (2014), AASHTO LRFD Bridge Design Specifications, Sixth Edition, American Association of State Highway and Transportation Officials, Washington, DC; Maddison, B., (2012), pp. 39-52. , Scour Failure of Bridges, Forensic Eng., 165 (1); (2012), FHWA, Evaluating Scour at Bridges, Fifth Edition, HEC-18, Federal Highway Administration, US Department of Transportation, Washington, DC; Ghosn, M., Moses, F., Wang, J., (2003), Design of Highway Bridges for Extreme Events, NCHRP Report 489, National Cooperative Research Program, Transportation Research Board, National Academy Press, Washington, DC; Banerjee, S., Prasad, G.G., (2011), Analysis of Bridge Performance under the Combined Effect of Earthquake and Flood induced Scour, Proc.

This work outlines the actual situation of complex degradation by ASR and salt damage of road bridge reinforced concrete slab in the Hokuriku district and introduces the history of the research and development of high-durability precast prestressed concrete (PCa PC) slab deck using fly ash concrete and examples of social implementation in this region. Moreover, full-size PCa PC slab specimens with and without fly ash content are constructed and subjected to both bending and pushing shear loading tests to investigate the differences in their bending and punching shear resistance. Numerical models are then developed using finite element method to evaluate the experimental results. Analyses elicited good agreement between simulations and experimental data and validated the numerical models. Based on the obtained results, this study clarified the mechanical properties of PCa PC slab using fly ash concrete, and then its practical use in the renewal project of highway was discussed. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.","bending loading test; fly ash concrete; Highly durable precast prestressed concrete slab; punching shear loading test; renewal project of highway","Bending tests; Calcium compounds; Deterioration; Fly ash; Highway bridges; Numerical methods; Numerical models; Precast concrete; Prestressed concrete; Reinforced concrete; Roads and streets; Silica; Bending loading; Fly ash concretes; Pre-cast; Punching shear; Renewal projects; Concrete slabs",,,,,"Japan Science and Technology Agency, JST","This research was promoted by the Cross-Ministerial Strategic Innovation Promotion Program [Resolution of Early-Aged Deterioration Mechanisms in Concrete Bridges and Development of Total Management System Based on Evaluation for Material and Structure Quality Performance, Kanazawa University] from the Japan Science and Technology Agency (JST).

In this study, the coupled vehicle-bridge model was established through SIMPACK and ANSYS; the 3D model of the bridge was established in ANSYS, and the vehicle model with 35 degrees of freedom (DOFs) was established in SIMPACK. The influence of the vehicle speed, pier height, track irregularity, and vehicle load on riding comfort was studied. Overall, straddle-type monorails had a good running stability, and the lateral comfort of the vehicle was better than the vertical comfort, due to symmetrical horizontal wheels. As the vehicle speed increased, the acceleration of the bridge and vehicle increased accordingly. Track irregularity had a substantial influence on riding comfort. Three types of track irregularity were simulated, and this factor should be strictly controlled to be smoother than the Chinese national A-level road roughness. The bridge pier height had a notable influence on the lateral riding comfort. In addition, this study attempted to improve riding comfort from the perspective of increasing the bridge stiffness, which could be achieved by increasing the cross-beam thickness or the track beam height. © 2020 by the authors.","Dynamic response; Riding comfort; Straddle-type monorail; Vehicle-bridge coupling vibration",,,,,,"National Natural Science Foundation of China, NSFC: 51778194; China Postdoctoral Science Foundation: 2017M621282; Fundamental Research Funds for the Central Universities: 2019056","Funding: This research was funded by the National Natural Science Foundation of China (grant No. 51778194), the China Postdoctoral Science Foundation (grant No. 2017M621282), and the Fundamental Research Funds for the Central Universities (grant No. HIT.

The proposed algorithm uses adaptive prior-based approach, which helps to generate the intermediate pdfs. Numerical analysis is carried out with different coefficient of variations of the prior for model updating. Guidelines for their proper selection procedure are also prescribed in this work. The efficiency of the proposed method is demonstrated using synthetic experiments and actual test data for updating the finite element model of a steel truss bridge.

The magnetic coupling test research was carried out for different grades of structural building and bridge steel specimens to establish the magnetic stress flux mathematical model, and the fitting equation of the magnetic flux changes with the positions of different sections of specimens was analyzed. Furthermore, a practical formula for stress detection was obtained through the experiments. Meanwhile, on these bases, the typical steel truss structure model of a Bailey beam was designed and manufactured under different working conditions, nondestructive online stress testing was carried out, and the stress of the model structure and its members was measured by strain and magnetic flux tests to obtain the curves of the test results for the stress–strain and magnetic stress flux, respectively. The results of these two methods are in good agreement with each other. The stress of the steel truss model structure was analyzed and calculated using the finite element method. The results agreed well with the experimental results from the magnetic stress sensing system—the maximum error was about 5%, which meets the requirements of engineering applications. © 2020 by the authors.

From a surveying or civil engineer's point of view, vibration-based SHM can be conducted by inspecting the changes in the global dynamic behaviour of a structure, such as natural frequencies (i. e. eigenfrequencies), mode shapes (i. e. eigenforms) and modal damping, which are known as modal parameters. This research work aims to propose a robust and automatic vibration analysis procedure that is so-called robust time domain modal parameter identification (RT-MPI) technique. It is novel in the sense of automatic and reliable identification of initial eigenfrequencies even closely spaced ones as well as robustly and accurately estimating the modal parameters of a bridge structure using low numbers of cost-effective micro-electro-mechanical systems (MEMS) accelerometers. To estimate amplitude, frequency, phase shift and damping ratio coefficients, an observation model consisting of: (1) a damped harmonic oscillation model, (2) an autoregressive model of coloured measurement noise and (3) a stochastic model in the form of the heavy-tailed family of scaled t-distributions is employed and jointly adjusted by means of a generalised expectation maximisation algorithm. Multiple MEMS as part of a geo-sensor network were mounted at different positions of a bridge structure which is precalculated by means of a finite element model (FEM) analysis. At the end, the estimated eigenfrequencies and eigenforms are compared and validated by the estimated parameters obtained from acceleration measurements of high-end accelerometers of type PCB ICP quartz, velocity measurements from a geophone and the FEM analysis. Additionally, the estimated eigenfrequencies and modal damping are compared with a well-known covariance driven stochastic subspace identification approach, which reveals the superiority of our proposed approach. We performed an experiment in two case studies with simulated data and real applications of a footbridge structure and a synthetic bridge. The results show that MEMS accelerometers are suitable for detecting all occurring eigenfrequencies depending on a sampling frequency specified. Moreover, the vibration analysis procedure demonstrates that amplitudes can be estimated in submillimetre range accuracy, frequencies with an accuracy better than 0.1 Hz and damping ratio coefficients with an accuracy better than 0.1 and 0.2 % for modal and system damping, respectively. © 2020 Walter de Gruyter GmbH, Berlin/Boston 2020.","Automatic modal parameters identification; Bridge monitoring; Double integration; EM algorithm; FEM analysis; MEMS accelerometer; Robust parameter estimation; Vibration analysis","Acceleration measurement; Accelerometers; Composite beams and girders; Cost effectiveness; Damping; Electric measuring bridges; Finite element method; MEMS; Modal analysis; Parameter estimation; Polychlorinated biphenyls; Sensor networks; Stochastic models; Stochastic systems; Structural health monitoring; Time domain analysis; Auto regressive models; Automatic procedures; Bridge infrastructure; Expectation-maximisation; Micro electromechanical system (MEMS); Sampling frequencies; Stochastic subspace identification; Structural health monitoring (SHM); Vibration analysis; automation; bridge; electrochemistry; electronic equipment; geophone; health monitoring; maintenance; PCB; quartz; vibration",,,,,,,,,,,,,,,,"Dawson, B., Vibration condition monitoring techniques for rotating machinery (1976) Shock Vib Dig, 8 (12), p. 3; Alvandi, A., Cremona, C., Assessment of vibration-based damage identification techniques (2006) J Sound Vib, 292 (1), pp. 179-202; Wenzel, H., (2009) Health Monitoring of Bridges, , United Kingdom John Wiley and Sons Ltd; Peeters, B., Maeck, J., De Roeck, G., Vibration-based damage detection in civil engineering: Excitation sources and temperature effects (2001) Smart Mater Struct, 10 (3), pp. 518-527; Rohrmann, R.G., Baessler, M., Said, S., Schmid, W., Ruecker, W.F., (2000) Proc. 18th Int.

However, most fatigue cracks which originate from the edge of cutouts are in fact detected in the diaphragms. Therefore, a retrofit technology on cracked cutouts at the diaphragm is proposed and applied to the orthotropic steel box girder of a suspension bridge. Firstly, the stress concentration on the cutout is analyzed through refined finite element analyses. Furthermore, the fatigue cracked cutouts are retrofitted by changing their geometrical parameters. Thereafter, an optimized geometry and the size of diaphragm cutouts were confirmed and applied in the rehabilitation of a suspension bridge. On-site wheel load tests were carried out before and after retrofitting of the diaphragm cutout. The stress distributions along the edges of the cutouts and at the side of a diaphragm were measured under a moving vehicle. The stress spectra at two critical locations on the edge of a cutout was obtained under longitudinally and laterally moving vehicles. Finally, the fatigue life of the cutouts is assessed by the modified nominal stress method. The analytical and test results indicate that the wheel loads on the deck transmit stress to the diaphragms through the U-ribs, during the load transmission process, the stress flow is obstructed by diaphragm cutouts, resulting in local stress concentrations around the cutouts. In addition, the overall size of the cutouts should be small, but the radius of the transition arc should be large, thus the stress flow will not be obviously obstructed. After the retrofitting of the cutouts by improved geometry, the maximum stress decreases by 87.6 MPa, which is about 40% of the original stress. The equivalent constant amplitude stress is reduced by 55.2% when the lateral position of the wheel loads is taken into consideration. Based on the stresses obtained by finite element analysis (FEA) and experimental tests, the fatigue lives of the original cutouts are 1.7 and 4.9 years, respectively, which increase to 78.1 and 155.5 years, respectively, after the cutouts were retrofitted, which indicates that the improved geometry and retrofit technology can enhance the fatigue performance and extend the fatigue life of diaphragm cutouts with fatigue cracks. © 2020 by the authors.","Diaphragm cutout; Fatigue assessment; Fatigue rehabilitation; Orthotropic steel deck; Stress spectrum",,,,,,"18ZDXK11, 19B013; European Commission, EC: 793787; National Natural Science Foundation of China, NSFC: 51708047, 51778069, 51978081; Natural Science Foundation of Hunan Province: 2019JJ50670","Funding: This research was funded by National Natural Science Foundation of China through Grant No. 51708047, 51778069 and 51978081; Horizon 2020-Marie Skłodowska-Curie Individual Fellowship of European Commission (REUSE: 793787); the Natural Science Foundation of Hunan Province through Grant No. 2019JJ50670; the Excellent youth project of Hunan Provincial Department of Education through Grant No. 19B013, and the Innovative projects in key disciplines through Grant No.18ZDXK11.",,,,,,,,,,"Li, C., He, J., Zhang, Z., Liu, Y., Ke, H., Dong, C., Li, H., An improved analytical algorithm on main cable system of suspension bridge (2018) Appl.

The accurate detection of the damage location using this index in a force system is dependent on the degree of accuracy in determining the structure deformation function before and after damage. The use of modal-based methods to identify damage in complex bridges is always associated with problems due to the need to consider the effects of higher modes and the adverse effect of operational conditions on the extraction of structural modal parameters. In this paper, the deformation of the structure was determined by the concept of influence line using the Betti-Maxwell theory. Then two damage detection indicators were developed based on strain energy variations. These indices were presented separately for bending and torsion changes. Finite element analysis of a five-span concrete curved bridge was done to validate the stated methods. Damage was simulated by decreasing stiffness at different sections of the deck. The response regarding displacement of a point on the deck was measured along each span by passing a moving load on the bridge at very low speeds. Indicators of the strain energy extracted from displacement influence line and the strain energy extracted from the rotational displacement influence line (SERIL) were calculated for the studied bridge. The results show that the proposed methods have well identified the location of the damage by significantly reducing the number of sensors required to record the response. Also, the location of symmetric damages is detected with high resolution using SERIL. © 2020, Higher Education Press.","complex bridges; damage detection; influence line; rotation displacement; strain energy","Deformation;

For the purpose of easy implementation of the present theory and the convenience of interested readers, we utilize the dynamic variational principles under the same framework of the (extended) Hamilton's principle to develop finite-element (FE) formulations for the dynamic responses of composite beams with Timoshenko's beam theory. The forced vibrations of composite beams are focused with a transverse point load, a moving mass, or a moving mass-spring-damper system, respectively, some of which are important in the consideration of the vehicle-bridge (structure) interaction. The explicit expressions of the local FE expressions are also given in the appendixes. The developed dynamic FE theoretical framework is validated against numerical results in the literature with excellent agreement. We believe that the present work provides a solid theoretical foundation for the future research of vehicle/load-composite beam interactions that have seldom been studied. © 2020 American Society of Civil Engineers.","Explicit finite elements; Forced vibrations; Mass-spring-damper; Partial-interaction composite beams; Vehicle-composite beam interaction","Finite element method; Variational techniques; Vibrations (mechanical); Explicit finite elements; Finite element formulations; Hamilton's principle; Partial interaction; Theoretical foundations; Theoretical framework; Timoshenko's beam theory; Variational principles; Composite beams and girders; damping; dynamic analysis; dynamic response; finite element method; loading; structural component; vibration",,,,,"16BS403, 51478422; National Natural Science Foundation of China, NSFC: 51608211; Natural Science Foundation of Fujian Province: 2017J05083; Fundamental Research Funds for the Central Universities: ZQN-711","The first author gratefully acknowledges the support by the National Natural Science Foundation of China (No. 51608211), the National Natural Science Foundation of Fujian Province (No. 2017J05083), the Fundamental Research Funds for the Central Universities (No. ZQN-711), and the Scientific Research Funds of Huaqiao University (No. 16BS403).

An analytical method considering axial equilibrium and shear deformation, which is referred to as PM, is proposed for overcoming the defect of the conventional method. The longitudinal displacement of the web is introduced to satisfy the axial equilibrium condition and locate the neutral axis automatically. The shear deformation is considered according to the Timoshenko beam theory. Three independent shear lag functions are adopted for describing different shear lag intensities of the top, bottom and cantilever slabs. The governing differential equations for the displacement variables are deduced by means of the virtual work theorem and solved with the relevant boundary conditions. The analytical solution is then derived for the distance from the neutral axis to the top fiber of the cross section. The accuracy of the proposed method is validated by comparisons with the available experimental data as well as the finite element analysis results. Moreover, the distances from the neutral axis to the top fiber, axial forces, and stress difference ratios are analyzed for typical thin-walled box girders to quantify the influence of the axial equilibrium condition. Finally, an extensive parametric study is conducted to examine the effects of various geometric parameters on the stress difference ratio under different load types. The results show that the proposed method can provide good predictions for both deflections and axial stresses, and neglecting axial equilibrium leads to considerable underestimations of axial stresses especially at the top flange-web junctions over the interior support of the continuous box girder. © 2020 Elsevier Ltd","Axial equilibrium; Axial force; Neutral axis; Shear lag; Stress difference ratio; Thin-walled box girder","Axial flow; Boundary conditions; Box girder bridges; Fiber optic sensors; Shear deformation; Thin walled structures; Axial forces; Neutral axis; Shear lag; Stress difference; Thin walled box girder; Beams and girders",,,,,"National Natural Science Foundation of China, NSFC: 51178416","The authors would like to gratefully acknowledge the financial support from the National Natural Science Foundation of China (No. 51178416 ).",,,,,,,,,,"Cheng, X.L., Chen, H., Gong, Y.Q., Yang, Y.B., Stocky thin- or thick-walled beams: theory and analysis (2018) Eng.

If the walls have flanged sections, substantial influences of the shear lag effect could be expected. This paper investigates the portion of shear deformation and influences of the shear lag effect in non-rectangular composite structural wall with different design parameters by finite element method. Methods for calculating the portion of shear deformation and shear lag effect in design are proposed based on a truss analogy. The study shows that a large portion of shear deformation exists for steel-concrete composite walls, which could account for more than 40% of the total deformation while vertical strain of the steel profiles at end of the flange of SRC walls is significantly smaller than assumed by plane section assumption. These effects can be captured reasonably by the proposed methods. © 2020","Composite steel and reinforced concrete; Shear deformation; Shear lag effect; Structural wall; Truss analogy method","Box girder bridges; Composite structures; Fiber optic sensors; Shear deformation; Shear flow; Trusses; Composite steel; Design parameters; Shear lag effects; Steel reinforced concrete; Steel-concrete composite; Strength and stiffness; Structural walls; Truss analogy; Reinforced concrete",,,,,,,,,,,,,,,,"Xu, P., Xue, Y., Xiao, C., Wang, C., Sun, H., Xu, Z., Gu, R., Experimental study on seismic performance of high-rise SRC hybrid structures (2005) Build.

To ensure antislip safety, the frictional resistance must be greater than the unbalanced cable tension. This study presents an innovative saddle to accommodate two main cables and analyzes the frictional resistance through mechanical analyses that were validated by finite-element analysis. A nonlinear finite-element model of a double-cable three-tower suspension bridge is established to determine the maximum unbalanced cable tension. The effects of key design parameters on antislip safety are investigated. The results reveal that the proposed saddle structure increases the frictional resistance. Strategies to enhance antislip safety include increasing the flexural stiffness of the middle tower, the ratio of dead load distribution, and the sag of the top cable. Decreasing the sag of the bottom cable helps improve the antislip safety of the top cable but compromises the safety of the bottom cable. This study provides new insights into the design and evaluation of multispan suspension bridges. © 2020 American Society of Civil Engineers.","Antislip safety; Double-cable suspension bridge; Friction resistance; Innovative saddle; Mechanical analyses; Nonlinear finite-element model","Finite element method; Friction; Stiffness; Suspension bridges; Design and evaluations; Friction resistance; Frictional resistance; Innovative saddle; Key design parameters; Mechanical analysis; Multi-span suspension bridges; Non-linear finite element model; Cables",,,,,"2011BAG07B03; BHSKL18-01-KF; 2017-538-2-1, 2017-538-2-4; National Natural Science Foundation of China, NSFC: 50908192, 51178394, 51378431, 51408506, 51578455, 51778533, 51878561","This study was funded by the National Natural Science Foundation of China (Grant numbers 51578455, 51878561, 51778533, 51378431, 51408506, 50908192, and 51178394), the Science and Technology Program of Hubei Transportation Department (Grant numbers 2017-538-2-1 and 2017-538-2-4), Open Key Fund Sponsored Program of State Key Laboratory for Bridge Health and Safety (Grant number BHSKL18-01-KF), and the National Science and Technology Support Program of China (Grant number 2011BAG07B03).",,,,,,,,,,"Chai, S., Xiao, R., Li, X., Longitudinal restraint of a double-cable suspension bridge (2014) J.

It is critical to ensure that the bridge will have adequate capacity to prevent collapse until the next cycle of inspection discovers the damage. It is realized that once one of the bridge girders is fractured, vertical loads need to be distributed through an alternative path to the intact girder(s). In this case, cross-frames can play an important role in transferring the loads and preventing from sudden collapse. This paper investigates the impact of cross-frames on load distribution after a fracture is occurred in one girder. Bridge configurations with different cross-frame spacing were studied using finite element modeling and simulation of the bridge behavior with a fractured steel plate girder. Nonlinear and dynamic solution methods were used for these analyses. Results of this investigation demonstrated the important role cross-frames can play in providing some reserved capacity for the bridge with fractured girder to enhance the bridge redundancy. The contribution of the cross-frames and the behavior of the bridge after fracture in one girder however depends on the configuration of the bridge. A study of the variation of the effect of cross-frames with respect to the number of girders is also included in this paper. © 2020 by the authors.","Cross-Frame; Finite element analysis; Fracture; Load distribution; Redundancy evaluation; Steel bridges",,,,,,,"Acknowledgments: The authors greatly acknowledge the internal support by the Department of Civil and Environmental Engineering at Florida International University.

A dynamic flexibility method (DFM) is adopted to decouple the multilayer substructures, which allows the interface forces among the substructures to be directly solved using a linear equation of deformation compatibility. The structural vibrations and power flows into each substructure can then be calculated. To illustrate the use of the DFM, a coupled train-Track-bridge system for urban rail transit traffic is investigated as a case study. Two infinite plate models are used to model the U-shaped bridge substructure to improve the computing efficiency compared with the finite element models in calculating high-frequency vibration. The applicability of the infinite plate models is discussed in terms of various rail positions on the bridge, the thickness of the rail support blocks, and multiple wheels that interface with the rail. The results show that the Mindlin plate model has similar accuracy but much greater computing efficiency than the finite element models. With the vibration results from the DFM, the associated wheel-rail noise and structure-borne noise from the bridge are then calculated together with a 2D acoustic model. Good agreement is observed between the predicted noises and the measured data. © 2020 World Scientific Publishing Company.","dynamic flexibility method; infinite plate; Multilayer structure; noise; train-Track-bridge system; vibration","Efficiency; Finite element method; Light rail transit; Mindlin plates; Multilayers; Structural dynamics; Wheels; Bridge substructures; Deformation compatibility; Discrete connections; High frequency vibration; Mindlin plate models; Multilayer structures; Structural vibrations; Structure-borne noise; Vibration analysis",,,,,"2017YFB1201302; National Natural Science Foundation of China, NSFC: 51878501, 51922080","The study was supported by the National Natural Science Foundation of China (Grant Nos. 51878501 and 51922080) and National Key Technologies Research and Development Program of China (Grant No. 2017YFB1201302).",,,,,,,,,,"Tsai, S., Taylor, A.C., Vibration behaviours of single/multi-debonded composite sandwich structures with nanoparticle-modified matrices Compos Struct, 210 (2019), pp. 590-598; Tomasin, M., Domaneschi, M., Guerini, C., Martinelli, L., Perotti, F., A comprehensive approach to small and large-scale effects of earthquake motion variability Comput.

However, the evaluation cannot be typically carried out by means of destructive tests on prototype or reduced scale structures. In this regard, the numerical models that adequately represent the prototype structures can be alternatively used. Specifically, both the nonlinearities and randomness as well as their coupling effect of materials need to be represented in a unified manner in structural analysis. The present paper aims at providing an effective approach to incorporate the stochastic nature of damage constitutive relationships in collapse analysis and assessment of concrete structures subjected to earthquake ground motions. Within the framework of stochastic damage mechanics, the spatial variability of concrete is represented by a two-scale stationary random fields. The concept of covariance constraint is introduced to bridge the two-scale random fields such that the scale-of-fluctuation of the random material property is satisfied at both scales. Random damage evolution induced structural collapse analysis is achieved via the nonlinear stochastic finite element method. To address the randomness propagation across scales, the probability density evolution method is employed. By exerting the absorbing boundary condition associated with an energy-based collapse criterion on the generalized probability density evolution equation, the anti-collapse reliability of concrete structures can be evaluated with fair accuracy and efficiency. Numerical investigation regarding an actual high-rise reinforced concrete frame-shear wall structure indicates that the random damage evolution of concrete dramatically affects the structural nonlinear behaviors and even leads to entirely different collapse modes. The proposed method provides a systematic treatment of both uncertainties and nonlinearities in collapse assessment of complex concrete structures. © 2020 Elsevier Ltd","Anti-collapse reliability; Energy-based collapse criterion; Multi-scale random fields; Probability density evolution method; Spatial correlation; Stochastic damage model","Concrete buildings; Concrete construction; Random processes; Reinforced concrete; Stochastic models; Stochastic systems; Structural analysis; Damage model; Energy-based; Probability density evolution method; Random fields; Spatial correlations; Damage detection",,,,,"National Natural Science Foundation of China, NSFC: 51538010, 51908224; China Postdoctoral Science Foundation: 2018M640783","Financial support from the National Natural Science Foundation of China (Grant Nos. 51908224 and 51538010 ) is gratefully appreciated.

Considering the damping effect, a local fine finite-element model is established to analyze the dynamic response of a typical continuous girder bridge. The displacements of the key points and the shear forces of the key components are both evaluated after taking into account the different earthquake ground motion characteristics and incident angles. The differences between the damping effects of these two devices are quantitatively analyzed. Then, each factor that potentially causes this difference is discussed to realize bidirectional control of vibrations in the seismic design of the bridge structure. © 2020 American Society of Civil Engineers.","Direction of ground motion; Friction coefficient; Gap; Local fine finite-element model; Predictability; Quasistatic test","Damping; Earthquakes; Friction; Seismic design; Continuous girder bridge; Control of vibrations; Earthquake ground motions; Friction coefficients; Ground motions; Material quantities; Predictability; Quasi-static tests; Finite element method",,,,,"National Natural Science Foundation of China, NSFC: 51438010, 51778498; Science and Technology Commission of Shanghai Municipality, STCSM: 17DZ1204300; National Key Research and Development Program of China, NKRDPC: 2018YFC1504306","This research was supported by the National Key Basic Research Program (Grant Number: 2018YFC1504306), National Science Foundation of China (Grant Number: 51438010, 51778498), and the Research Program of the Shanghai Science and Technology Commission (Grant Number: 17DZ1204300).

A near-surface mounted strengthening system has been adopted to protect the fibre-reinforced polymer bars from external hazards. To make up the lower stiffness and ductility of fibre-reinforced polymer bar compared to steel rebar, this study proposed to use a pre-stressed near-surface mounted steel–basalt-fibre-reinforced polymer composite bar. The steel–basalt-fibre-reinforced polymer composite bar is manufactured through wrapping a steel rod by a basalt-fibre-reinforced polymer cover. A total of nine reinforced concrete beams, including one control or calibration and eight others strengthened by pre-stressed near-surface mounted steel–basalt-fibre-reinforced polymer composite bars, are fabricated and tested. Results show that the proposed steel–basalt-fibre-reinforced polymer composite bar strengthening method can improve both the strength and ductility of the reinforced concrete beams. Pre-stressing of the steel–basalt-fibre-reinforced polymer composite bars further increases substantially the beams’ load-carrying capacity by restraining crack propagation in concrete. Standard-based load analysis correctly predicts the cracking load, however, underestimates the ultimate strength of the beams. Finite element method modelling is conducted to provide a more effective load-carrying capacity prediction and a case study is carried out with regard to the amount of the strengthening steel–basalt-fibre-reinforced polymer composite bars. © The Author(s) 2019.","basalt-fibre-reinforced polymer; composite bar; concrete beam; load-carrying capacity; near-surface mounted; pre-stressed bar","Bars (metal); Basalt; Bridge decks; Concrete beams and girders; Corrosion resistance; Cracks; Ductility; Fiber reinforced plastics; High performance concrete; Load limits; Loads (forces); Polymers; Prestressed concrete; Steel fibers; Strengthening (metal); Tensile strength; Concrete beam; Fibre reinforced polymer bars; Fibre reinforced polymers; Fibre-reinforced polymer composites; Near surface mounted; Pre-stressed; Reinforced concrete beams; Strength and ductilities; Reinforced concrete",,,,,"Australian Research Council, ARC: DP160100119, IH150100006",,,,,,,,,,,"Al-Bayati, G., Al-Mahaidi, R., Kalfat, R., Experimental investigation into the use of NSM FRP to increase the torsional resistance of RC beams using epoxy resins and cement-based adhesives (2016) Construction and Building Materials, 124, pp. 1153-1164; Al-Mahmoud, F., Castel, A., François, R., Strengthening of RC members with near-surface mounted CFRP rods (2009) Composite Structures, 91 (2), pp. 138-147; Almassri, B., Al Mahmoud, F., Francois, R., Behaviour of corroded reinforced concrete beams repaired with NSM CFRP rods, experimental and finite element study (2016) Composites Part B: Engineering, 92, pp. 477-488; Almassri, B., Kreit, A., Al Mahmoud, F., Mechanical behaviour of corroded RC beams strengthened by NSM CFRP rods (2014) Composites Part B: Engineering, 64, pp. 97-107; Aslam, M., Shafigh, P., Jumaat, M.Z., Strengthening of RC beams using pre-stressed fiber reinforced polymers – a review (2015) Construction and Building Materials, 82, pp. 235-256; Atutis, M., Valivonis, J., Atutis, E., Experimental study of concrete beams pre-stressed with basalt fiber reinforced polymers.

For a specific multi-tower suspension bridge, the midtower longitudinal stiffness must be controlled within a certain range to meet the requirements of sliding resistance coefficient and deflection-to-span ratio. This study presents a numerical method to divide different types of midtower and determine rational range of longitudinal stiffness for rigid midtower. In this method, influence curves of midtower longitudinal stiffness on sliding resistance coefficient and maximum vertical deflection-to-span ratio are first obtained from the finite element analysis. Then, different types of midtower are divided based on the regression analysis of influence curves. Finally, rational range for longitudinal stiffness of rigid midtower is derived. The Oujiang River North Estuary Bridge which is a three-tower four-span suspension bridge with two main spans of 800m under construction in China is selected as the subject of this study. This will be the first three-tower four-span suspension bridge with steel truss girders and concrete midtower in the world. The proposed method provides an effective and feasible tool for engineers to design midtower of multi-tower suspension bridges.

Institute for Research in Technology (ETSI-ICAI), Madrid, 28015, Spain","Vibration-based damage identification of large and complex structures requires a huge computational effort to solve an ill-posed inverse problem with a large number of unknowns. Moreover, due to the limited number of measurement sensors, the capability to detect damage is quite limited. To mitigate these disadvantages, a two-stage model updating method based on the proposed novel localised damage function approach called roaming damage method (RDM) is proposed. The roaming damage method has the ability to identify a wide range of damage types, from large areas of low damage to individual beams which have been severely damaged. The approach can be applied to complex and refined 3D finite element models in only two steps. To enhance identification, the optimization procedure is formulated in a multi-objective context dependent on a spectrum-driven feature that is based on the Power Mode Shapes (PMS) from measured responses. Unlike conventional mode shapes, PMSs contain information from the entire frequency range. The well-known case study of the I-40 bridge in New Mexico is chosen to apply and further investigate this technique with the aim of testing its reliability. The simulated dynamic data obtained from random vibrations are employed to evaluate the performance of the method. Two additional features to improve the proposal, the ANN enhanced PMS RMD and RDM with adaptive radius, have also been explored. © 2020 Elsevier Ltd","Adaptive method; Large structures; Multistage damage identification; Neural networks; Power mode shapes; Roaming damage method","Complex networks; Finite element method; Inverse problems; Neural networks; Well testing; Adaptive methods; Damage Identification; Large structures; Power modes; Roaming damage method; Damage detection; algorithm; artificial neural network; bridge; finite element method; identification method; reliability analysis; shape; structural analysis; three-dimensional modeling; vibration; New Mexico; United States",,,,,"Ministry of Economy, Trade and Industry, METI: BIA2017-84975-C2-1-P; Ministerio de Economía, Industria y Competitividad, Gobierno de España, MINECO","We are grateful to the Spanish Ministry of Economy, Industry and Competitiveness (project BIA2017-84975-C2-1-P) for supporting the work reported in this paper.","We are grateful to the Spanish Ministry of Economy, Industry and Competitiveness (project BIA2017-84975-C2-1-P ) for supporting the work reported in this paper.",,,,,,,,,"Ko, J.M., Ni, Y.Q., Technology developments in structural health monitoring of large-scale bridges (2005) Eng.

Corrugated web girders are widely used in bridge construction and as a result, are subjected to patch loads especially during the construction stage and are prone to buckling. Patch load capacity of corrugated webs is found to be sensitive to the static systems of the girder. In this paper, an extensive parametric study on different static forms, loading, and geometric parameters is carried out using a validated numerical model to develop a better understanding of the structural behavior of corrugated web girders subjected to patch loading. Furthermore, previous design proposals from the literature have been summarized. Based on numerical studies, an empirical model is prescribed for the determination of the ultimate patch load capacity of girders having cantilever spans. © 2019 Elsevier Ltd","Corrugated web; FEM analysis; Non-linear behavior; Patch load; Static forms; Ultimate load behavior","Beams and girders; Bridges; Bridge constructions; Construction stages; Corrugated web; Corrugated web girders; FEM analysis; Nonlinear behavior; Structural behaviors; Ultimate loads; Loading",,,,,,,,,,,,,,,,"Yokota, T., Junichi, S., Yutaka, H., Taisuke, U., The structural planning and design of the Aigawa Bridge on new Meishin expressway, proceedings of the 23th symposium on developments in prestressed concrete (2014) Japan Prestressed Concrete Institution (JPCI), pp. 503-506; Luo, R., Edlund, B., Ultimate strength of girders with trapezoidally corrugated webs under patch loading (1996) Thin-Walled Struct., 24, pp. 135-156; EN 1993-1-5: Eurocode3, Design of Steel Structures, Part 1–5: Plated Structural Elements (2005); Yi, J., Gil, H., Youm, K., Lee, H., Interactive shear buckling behavior of trapezoidally corrugated steel webs (2008) Eng.

Model updating of nonlinear mechanics-based Finite Element (FE) models using input and output measurement data with advanced Bayesian inference methods is an effective way of constructing a digital twin. In this regard, the nonlinear FE model updating of a full-scale reinforced-concrete bridge column subjected to seismic excitations applied by a large shake table is considered in this paper. This bridge column, designed according to US seismic design provisions, was tested on the NEES@UCSD Large High-Performance Outdoor Shake Table (LHPOST). The column was subjected to a sequence of ten recorded earthquake ground motions and was densely instrumented with an array of 278 sensors consisting of strain gauges, linear and string potentiometers, accelerometers and Global Positioning System (GPS) based displacement sensors to measure local and global responses during testing. This heterogeneous dataset is used to estimate/update the material and damping parameters of the developed mechanics-based distributed plasticity FE model of the bridge column. The sequential Monte Carlo (SMC) method (set of advanced simulation-based Bayesian inference methods) is used herein for the model updating process. The inherent architecture of SMC methods allows for parallel model evaluations, which is ideal for updating computationally expensive models. © 2020, The Society for Experimental Mechanics, Inc.","Bayesian inference; Digital twin; Earthquake; Finite element; Full-scale structural systems; Model updating; Sequential Monte Carlo; Structural health monitoring","Bayesian networks; Earthquakes; Finite element method; Global positioning system; Inference engines; Reinforced concrete; Seismic design; Structural health monitoring; Voltage dividers; Bayesian inference; Bridge columns; Earthquake; Finite element modelling (FEM); Finite-element model updating; Full-scale structural system; Model updating; Non-linear finite element modeling; Sequential Monte Carlo; Structural systems; Monte Carlo methods",,,,,"Engineer Research and Development Center, ERDC: W912HZ-17-2-0024; U.S. Army Corps of Engineers, USACE","Acknowledgements Funding for this work was provided by the U.S. Army Corps of Engineers through the U.S. Army Engineer Research and Development Center Research Cooperative Agreement W912HZ-17-2-0024.",,,,,,,,,,"Kadry, S., Diagnostics and prognostics of engineering systems: Methods and techniques (2012) Diagnostics Prognostics of Engineering Systems: Methods and Techniques, pp. 1-433. , pp., IGI Global, Hershey; Farrar, C.R., Worden, K., An introduction to structural health monitoring (2007) Math Phys Eng Sci, 365, pp. 303-315; Farrar, C.R., Worden, K., (2012) Structural Health Monitoring: A Machine Learning Perspective, , Wiley, Chichester; Astroza, R., Ebrahimian, H., Conte, J.P., Material parameter identification in distributed plasticity FE models of frame-type structures using nonlinear stochastic filtering (2015) J.

When a NSPMSM is operating at or below the rated speed, the id is flux-intensifying current, which can improve the flux density of permanent magnets (PM). First, a NSPMSM is proposed and compared with a positive-salient permanent magnet synchronous motor (PSPMSM). The d-axis and q-axis equivalent magnet circuits of the NSPMSM are then established. According to the limitation of the equivalent magnet circuit, the PM dimensions formula and optimization of the finite element method (FEM), PM dimensions are determined, and the constant power speed ranges of the two motors are calculated. Second, the influence of the saliency ratio on the internal power factor angle and the average flux density of PM at different internal power factor angles are calculated. Third, the flux density of PM in two motors are calculated when the windings are short-circuited. Finally, the bypass function of the NSPMSM magnetic bridges during the flux-weakening state is analyzed. The results show that the flux-weakening magneto motive force (MMF) of the NSPMSM is smaller at high speed, the short-circuit current (SCC) is smaller when the windings are short-circuited, and the magnetic bridges protect the PM in the flux-weakening state, so the flux density of PM is larger. © 2020 Institute of Electrical and Electronics Engineers Inc..

In order to clarify the mechanism of temperature-induced deformation and its impact on structural stress distribution, this article reports on the temperature distribution and its effect on the deformation of concrete truss combination arch bridge based on bridge health monitoring on a proto bridge with 138 m main span. The temperature distribution and deformation characteristics of the bridge structure in deep valley area are studied. Both of the daily and yearly temperature variation and structural deformation are studied based on bridge health monitoring. Using the outcome of monitoring data, three-dimensional solid finite element models are established to analyze the mechanism of temperature-induced deformation of the whole bridge under different temperature fields. The influence of temperature-induced effect is discussed on local damage based on the damage observation of the background bridge. The outcome of comparisons with field observation validates the analysis results. The relevant monitoring and simulation result can be referenced for the design and evaluation of similar bridges. © The Author(s) 2020.","Arch bridge; deflection; finite element method; health monitoring;

The assessment of ageing reinforced concrete bridge stock may need to consider corrosion and cracks, as the likelihood of deterioration increases with age. This work accordingly investigates the incorporation of pre-existing anchorage zone corrosion cracks into the finite element modelling of reinforced concrete beam structural behaviour. Three methods of accounting for cracks were applied: (1) modifying the bond stress–slip relation, (2) weakening elements at the position of the crack, and (3) weakened discrete crack elements. The results show that modifying the bond stress–slip relation results in accurate predictions of the ultimate capacity when one-dimensional reinforcement bars are used in the model. Weakening elements at the position of the crack provides reasonable results when the anchorage is modelled with three-dimensional reinforcement bars and a frictional bond model. The implementation of discrete cracks was found to be unsuitable for the studied load situation, as compressive stresses formed perpendicular to the crack. It was concluded that the capacity of the studied case could be well estimated based on visual measurements, without knowledge of the exact corrosion level. © 2020, © 2020 The Author(s).

Vibration analysis of these types of columns is essential to understand the failure modes of such columns. In that aspect, this study aims to analyze a concrete-encased built-up column made by configuring cold-formed steel angle sections connected by means of battens encased by normal weight and lightweight concrete with and without the inclusion of basalt fibre. Eight columns with battens were simulated, and it is encased with four different types of concrete and subjected to axial cyclic loading. The experimental results were correlated with the numerical investigation performed using FEA. The results indicated that the type of concrete dramatically influences the behaviour of columns. Higher ultimate strength and ductility was observed for all specimens, which is due to lower shear capacity of the battens. It was observed that the intensity of the axial cyclic load has a significant effect on the ultimate strength and deflection of columns, but it is less influential on the yield strength. It was concluded the results of experimental and FEA shows good compatibility between each other and depicts an error of 7.48%. © 2020.","Basalt Fibre; Battened built-up Column; Deformation; FEA; Sintered Fly ash lightweight concrete; Strain Behaviour","Bridges; Columns (structural); Cyclic loads; Steel fibers; Tall buildings; Vibration analysis; Cold-formed steel; Composite column; Concrete-encased; Design and analysis; Experimental and numerical analysis; Good compatibility; Numerical investigations; Ultimate strength; Light weight concrete",,,,,,,,,,,,,,,,"(2001) Load and Resistance Factor Design Specification for Structural Steel Buildings, , Chicago, IL: American Institute of Steel Construction; Aslani, F., Goel, S.C., Analytical criterion for buckling strength of builtup compression members (1991) Engineering Journal, American Institute of Steel Construction, 28, pp. 159-168; Aslani, F., Goel, S.C., Stitch spacing and local buckling in seismic resistant double-angle braces (1991) Journal of Structural Engineering Division ASCE, 117 (8), pp. 2442-2463; Astaneh-Asl, A., Goel, S.C., Hanson, R.D., Cyclic out-of-plane buckling of double angle bracing (1985) Journal of Structural Engineering, 111 (5), pp. 1135-1153; Hashemi, B.H., Bonab, A.P., Experimental investigation of the behavior of laced columns under constant axial load and cyclic lateral load (2013) Engineering Structures, 57, pp. 536-543; (2007) Code of Practice for General Construction in Steel, , New Delhi: Bureau of Indian Standards; (1975) Code of Practice for Use of Cold Formed Light Gauge Steel Structural Members in General Building Construction, , New Delhi: Bureau of Indian Standards, (Reaffirmed 2001); Bleich, F., (1952) Buckling Strength of Metal Structures, , 2nd edition.

The main tests to be conducted for the homologation of the vehicle tank is the burst pressure, which is a quasi-static test. This method aims to reduce the finite element model development time by the integration between the computational software MATLAB and the FEA tool Abaqus. Since the dome shape has fundamental influence on the mechanical performances of the composite pressure vessel, the presented procedure allows the designer to quickly import the suitable dome geometry into Abaqus, without the need of going through CAD software. The first step of the method here reported is the definition of all the geometric and operational parameters necessary to the construction of the dome meridian profile. The second step is to enter those parameters in a MATLAB script, which is able to integrate the dome profile differential equation, to generate the whole tank profile and to import this profile into Abaqus. Once the geometry has been imported, a FE model of the high-pressure vessel can be built and virtual simulations can be performed. This approach could be implemented in a dome optimization process to find which dome meridian profile gives the best tank performances. © 2020 CAD Solutions, LLC,.","Composite Vessels; Filament Winding; Virtual Prototyping","ABAQUS; Bridge decks; Design; Differential equations; Domes; Geometry; MATLAB; Pressure vessels; Tanks (containers); Virtual prototyping; Composite pressure vessels; Composite vessels; Computational software; Design of composites; High-pressure vessel; Mechanical performance; Methodological approach; Operational parameters; Filament winding",,,,,,,,,,,,,,,,"Barthelemy, H., Weber, M., Barbier, F., Hydrogen storage: Recent improvements and industrial perspectives (2017) International Journal of Hydrogen Energy, 42, pp. 7254-7262. , https://doi.org/10.1016/j.ijhydene.2016.03.178; Castorani, V., Landi, D., Mandolini, M., Germani, G., Design optimization of customizable centrifugal industrial blowers for gas turbine power plants (2019) Computer-Aided Design and Applications, 16 (6), pp. 1098-1111. , https://doi.org/10.14733/cadaps.2019.1098-1111; Cicconi, P., Landi, D., Germani, M., A virtual modelling of a hybrid road tractor for freight delivery (2016) ASME International Mechanical Engineering Congress and Exposition, Proceedings (IMECE); Cronin, J., Mallick, K., Lake, M., Warner, M., Munshi, N., (2011) Damage and Leakage Barrier in All-Composite Pressure Vessels and Storage Tanks, , U.S. Patent 8,074,826 B2, December 13; Hong, J.-H., Han, M.-G., Chang, S.-H., Safety evaluation of 70 MPa-capacity type III hydrogen pressure vessel considering material degradation of composites due to temperature rise (2014) Composite Structures, 113, pp. 127-133. , https://doi.org/10.1016/j.compstruct.2014.03.008; Hua, T.-Q., Roh, H.-S., Ahluwalia, R.-K., Performance assessment of 700-bar compressed hydrogen storage for light duty fuel cell vehicles (2017) International Journal of Hydrogen Energy, 42, pp. 25121-25129. , https://doi.org/10.1016/j.ijhydene.2017.08.123; Johnosn, K., Veenstra, M., Gotthold, D., Simmons, K., Advancements and opportunities for on-board 700 bar bompressed hydrogen tanks in the progression towards the commercialization of fuel cell vehicles (2017) SAE International Journal of Alternative Powertrains, 6 (2), pp. 201-218. , https://doi.org/; Kerviel, A., Pesyridis, A., Chalet, D., Boosting system options for high efficiency fuel cell electric vehicles, 4th Biennal International Conference on Powertrain Modelling and Control Testing (2018) Mapping and Calibration; Koussios, S., (2009) Design of Cylindrical Composite Pressure Vessels: Integral Optimization, , 17th International Conference on Composite Materials, Edinburgh, UK; Koussios, S., Lei, Z., Tapeinos, I.G., Beukers, A., Sippel, M., Kopp, A., Some observations on the influence of the classic failure criteria on the optimal design of pressure vessels (2017) Proceedings of the American Society for Composites, 4 (11), pp. 617-625; Parmar, K.-R., Khan, A.-A., Khiraiya, K.-B., Comparative FE analysis of pressure vessel of hemispherical, ellipsoidal and torospherical end connection (2014) International Journal of Engineering Development and Research, 3, pp. 46-50; Peters, S.-T., (2011) Composite Filament Winding, , ASM International; Ramirez, J.P.-B., Halm, D., Grandidier, J.-C., Villalonga, S., Nony, F., 700 bar type IV high pressure hydrogen storage vessel burst – Simulation and experimental validation (2015) International Journal of Hydrogen Energy, 40 (38), pp. 13183-13192. , https://doi.org/10.1016/j.ijhydene.2015.05.126; Roh, H.-S., Hua, T.-Q., Ahluwalia, R.-K., Optimization of carbon fiber usage in Type 4 hydrogen storage tanks for fuel cell automobiles (2013) International Journal of Hydrogen Energy, 38 (29), pp. 12795-12802. , https://doi.org/10.1016/j.ijhydene.2013.07.016; Villalonga, S., Thomas, C., Nony, F., Thiebaud, F., Geli, M., Lucas, A., Kremer-Knobloch, K., Maugy, C., Application of full thermoplastic composite for type IV 70MPa high pressure vessel (2011) 18Th International Conference on Composite Materials, , August; Xu, P., Zheng, J.-Y., Liu, P.-F., Finite element analysis of composite hydrogen storage vessel (2009) Materials and Design, 31 (7), pp. 2295-2301. , https://doi.org/10.1016/j.matdes.2009.03.006; Yamashita, A., Kondo, M., Goto, S., Ogami, N., Development of high-pressure hydrogen storage system for the Toyota “Mirai” (2015) SAE Technical Paper, 1, pp. 1169-1181. , https://doi.org/; Zheng, J., Liu, X., Xu, P., Liu, P., Zhao, Y., Yang, J., Development of high-pressure gaseous hydrogen storage technologies (2012) International Journal of Hydrogen Energy, 37 (1), pp. 1048-1057. , https://doi.org/10.1016/j.ijhydene.2011.02.125","Landi, D.; Ancona Università politecnica delle MarcheItaly; email: d.landi@univpm.it",,,"CAD Solutions, LLC",,,,,16864360,,,,"English","Comput.-Aided Des.

Owing to the unique temperature conditions in Tibet, there have been no large-scale experimental studies on the thermal load design of CFST bridges in this area. Therefore, to determine the thermal load calculation parameters and thermal effects of Zangmu Bridge, a long-term continuous field test was conducted to measure the temperature variations in a test arch with the same pipe diameter. The test results were then compared with current design specifications and relevant literature. Finally, the thermal effects in a CFST arch bridge were analysed using the finite element method. According to the results, the following recommendations were made: (1) the average temperature of concrete in the pipe after the formation of concrete strength should be used to calculate the closure temperature of CFST arch bridges in Tibet; however, the standard calculation formula was still applicable; (2) the daily average temperature in extreme weather should be taken as the maximum and minimum effective temperature; (3) we presented recommended values for the influence range and gradient temperature for a single large-diameter pipe; and (4) a refined finite element model that included the arch base should be used to verify the temperature effects during bridge design. © 2020 Tuo Shi et al.",,"Arch bridges; Arches; Concrete pipe; Extreme weather; Finite element method; Thermal load; Tubular steel structures; Closure temperatures; Concrete-filled steel tube arch bridge; Concrete-filled steel tubes; Effective temperature; Large diameter pipes; Temperature conditions; Temperature variation; Thermal load calculations; Concretes",,,,,"National Natural Science Foundation of China, NSFC: 51738004, 51868006, 51878186; Science and Technology Major Project of Guangxi: AA18118029","The authors would like to thank China Railway Guangzhou Engineering Group Co., Ltd, for the materials used for experiments and Editage (http://www.editage.cn) for the English language editing.

This article proposes an analytical solution for the lateral-torsional buckling (LTB) of concrete-filled tubular flange steel girders with torsional bracing under a concentrated load. The modal trial functions of lateral displacement and the torsional angle are expressed by the first six terms of the trigonometric function. By introducing dimensionless parameters, the variational solution of energy for the buckling equation of the LTB of the girders is obtained, and the formula for the dimensionless critical moment of its LTB is derived using 1stOpt based on 32,550 data sets. Compared with the finite element method, the proposed critical formula is highly accurate and can be applied to engineering design. Finally, parametric studies were conducted on the effects of the stiffness of torsional bracing, the span of the girder, and the flange steel ratio. © 2020 Yingchun Liu et al.",,,,,,,,,,,,,,,,,,"Sause, R., Kim, B.-G., Wimer, M.R., Experimental study of tubular flange girders (2008) Journal of Structural Engineering, 134 (3), pp. 384-392. , 2-s2.0-39449089193; Kim, B.-G., Sause, R., Lateral torsional buckling strength of tubular flange girders (2008) Journal of Structural Engineering, 134 (6), pp. 902-910. , 2-s2.0-43949129430; Dong, J., Sause, R., Flexural strength of tubular flange girders (2009) Journal of Constructional Steel Research, 65 (3), pp. 622-630. , 2-s2.0-58149127841; Hassanein, M.F., Kharoob, O.F., Shear strength and behavior of transversely stiffened tubular flange plate girders (2010) Engineering Structures, 32 (9), pp. 2617-2630. , 2-s2.0-77955511214; Hassanein, M.F., Kharoob, O.F., Flexural strength of hollow tubular flange plate girders with slender stiffened webs under mid-span concentrated loads (2013) Thin-Walled Structures, 69, pp. 18-28. , 2-s2.0-84877818602; Sause, R., Innovative steel bridge girders with tubular flanges (2015) Structure and Infrastructure Engineering, 11 (4), pp. 450-465. , 2-s2.0-84919663743; Shao, Y., Wang, Y., Experimental study on static behavior of I-girder with concrete-filled rectangular flange and corrugated web under concentrated load at mid-span (2017) Engineering Structures, 130, pp. 124-141. , 2-s2.0-84992038045; Wang, C.S., Zhu, J.W., Zhai, X.L., Wang, X.P., Liu, H., Flexural behavior experiment of steel and concrete composite girder with double tubular flanges (2017) China Journal of Highway Transport, 30 (3), pp. 147-158; Pan, J., Wang, P., Zheng, Y., Wang, Z., Liu, D., An analytical study of square CFT columns in bracing connection subjected to axial loading (2018) Advances in Civil Engineering, 2018, p. 15. , 8618937 2-s2.0-85058818741; Tong, G.S., Chen, S.F., Buckling of laterally and torsional braced beams (1988) Journal of Constructional Steel Research, 11 (1), pp. 41-55; Valentino, J., Pi, Y.-L., Trahair, N.S., Inelastic buckling of steel beams with central torsional restraints (1997) Journal of Structural Engineering, 123 (9), pp. 1180-1186; Khelil, A., Larue, B., Simple solutions for the flexural-torsional buckling of laterally restrained I-beams (2008) Engineering Structures, 30 (10), pp. 2923-2934. , 2-s2.0-52749093716; Nguyen, C.T., Moon, J., Le, V.N., Lee, H.-E., Lateral-torsional buckling of I-girders with discrete torsional bracings (2010) Journal of Constructional Steel Research, 66 (2), pp. 170-177. , 2-s2.0-71849110353; Nguyen, C.T., Joo, H.-S., Moon, J., Lee, H.-E., Flexural-torsional buckling strength of I-girders with discrete torsional braces under various loading conditions (2012) Engineering Structures, 36, pp. 337-350. , 2-s2.0-84862797522; Mohammadi, E., Hosseini, S.S., Rohanimanesh, M.S., Elastic lateral-torsional buckling strength and torsional bracing stiffness requirement for monosymmetric I-beams (2016) Thin-Walled Structures, 104, pp. 116-125. , 2-s2.0-84960863208; Zhang, W.F., (2018) Out-of-Plane Stability Theory of Steel Structures, , Wuhan, China Wuhan University of Technology Press in Chinese; Tong, G.S., (2006) Out-Plane Stability of Steel Structures, , Beijing, China China Architecture and Building Press in Chinese; Chen, J., (2014) Stability of Steel Theory and Design, , 6th Beijing, China Science Press in Chinese; Achref, H., Foudil, M., Cherif, B., Higher buckling and lateral buckling strength of unrestrained and braced thin-walled beams: Analytical, numerical and design approach applications (2019) Journal of Constructional Steel Research, 155, pp. 1-19. , 2-s2.0-85059350139; Zhang, W.F., New Engineering Theory for Torsional Buckling of Steel-concrete Composite I-columns, 12, pp. 225-232. , Proceedings of the 11th International Conference on Advances in Steel and Concrete Composite Structures 2012 Beijing, China; Zhang, W.F., Energy Variational Model and Its Analytical Solutions for the Elastic Flexural-torsional Buckling of I-beams with Concrete-filled Steel Tubular Flanges, pp. 1100-1108. , Proceedings of the 8th International Symposium on Steel Structures 2006 Jeju, South Korea; Zhang, W.F., New Engineering Theory for Mixed Torsion of Steel-concrete-steel Composite Walls, 12, pp. 705-712. , Proceedings of 11th International Conference on Advances in Steel and Concrete Composite Structures 2010 Beijing, China; Chen, K.S., (2017) Theoretical Research on Combined Torsion and Flexural-Torsional Buckling of the I-Shaped Beams with Concrete-Filled Steel Tubular Flange Based on the Plate-Beam Theory, , Daqing, China Northeast Petroleum University Master dissertation; Chen, W.F., Lui, E.M., (1987) Structural Stability-Theory and Implementation, , 1st New York, NY, USA Elsevier Science Publishing Co.

The glass fibre-reinforced polymer–metal emergency bridge is intended to be lightweight, structurally sound, with a long span and modular feasibility, and associated with a faster construction bridging system. In this study, the detailed conceptual design of the new bridge is described first. A large-scale static bending loading test was carried out on a fabricated bridge to examine its actual flexural performance under the serviceability limit state. The experimental emergency bridge exhibited a satisfactory overall stiffness and loading-carrying capacity in terms of its intended applications. Its linear-elastic flexural behaviour implies that the structural design of such a unique emergency bridge subjected to positive flexural moment is stiffness-driven instead of strength-driven. Furthermore, structural computational models, including three-dimensional finite element models and a simplified analytical planar model, were constructed and validated by comparing with the experimental results. The elicited comparisons indicated that the realistic nodal stiffness of the hybrid pre-tightened teeth connection and its adjacent steel planar gusset plates ought to be considered in numerical and analytical modelling. Correspondingly, during the preliminary design phase and calculations, the flexural behaviour of this unique emergency bridge can be predicted using the validated numerical and simplified analytical models. © The Author(s) 2019.","bridge engineering; fibre-reinforced polymer; finite element analysis; flexural performance; hybrid structure; non-destructive static test; string structure; truss","Analytical models; Bridge decks; Conceptual design; Concrete beams and girders; Fiber reinforced plastics; Finite element method; Glass fibers; Polymers; Reinforcement; Stiffness; Trusses; Bridge engineering; Fibre reinforced polymers; Flexural performance; Hybrid structure; Static tests; Structural design",,,,,"National Natural Science Foundation of China, NSFC: 51708552; China Postdoctoral Science Foundation: 2017M623401; Natural Science Foundation of Jiangsu Province: BK20170752","The author(s) disclosed receipt of the following financial support for the research, authorship and/or publication of this article: Financial supports from the National Natural Science Foundation of China (51708552), the Natural Science Foundations of Jiangsu Province (BK20170752), the Postdoctoral Science Foundation Grant of China (2017M623401) and the Young Elite Scientist Sponsorship are gratefully acknowledged.",,,,,,,,,,"Alampalli, S., Field performance of an FRP slab bridge (2006) Composite Structures, 72 (4), pp. 494-502; Aparicio, A.C., Ruiz-Teran, A.M., Two new types of bridges: under-deck cable-stayed bridges and combined cable-stayed bridges – the state of the art (2007) Canadian Journal of Civil Engineering, 34 (8), pp. 1003-1016; Bai, Y., Yang, X., Novel joint for assembly of all-composite space truss structures: conceptual design and preliminary study (2013) Journal of Composites for Construction, 17 (1), pp. 130-138; Bao, S.H., Gong, Y.Q., (2006) Structural Mechanics, , Wuhan, China, Wuhan University of Technology Press; Chen, R.Y., Dong, S.L., Design of exhibition hall steel roof at Guangzhou international convention & exhibition center (2002) Spatial Structures, 8 (3), pp. 29-34; Correia, J.R., Bai, Y., Keller, T., A review of the fire behaviour of pultruded GFRP structural profiles for civil engineering applications (2015) Composite Structures, 127, pp. 267-287; Feng, P., Tian, Y., Qin, Z.P., Static and dynamic behavior of a truss bridge made of FRP pultruded profiles (2013) Industrial Construction, 43 (6), pp. 36-41; Foss, C.F., Gander, T.J., (2001) Jane’s Military Vehicles and Logistics, , London, Jane’s Information Group; Gand, A.K., Chan, T.M., Mottram, J.T., Civil and structural engineering applications, recent trends, research and developments on pultruded fiber reinforced polymer closed sections: a review (2013) Frontiers of Structural and Civil Engineering, 7 (3), pp. 227-244; (1992) General code for military bridge design, , China National Military Standard, Beijing, China, Technical report; (1988) General code for design load for military bridges, , China National Military Standard, Beijing, China, Technical report; Hu, Y.P., (2008) Structural Design and Erection Methods for Military Bridges, , Beijing, China, PLA Press; Iwao, S., Itaru, N., (2010) Load-bearing properties of an FRP bridge after nine years of exposure, pp. 474-477. , Proceedings of the CICE 2010 – the 5th international conference on FRP composites civil engineering, Beijing, China, 27–29, September, Berlin, Springer, In; Ji, H.S., Song, W.C., Ma, Z.G.J., Design, test and field application of a GFRP corrugated-core sandwich bridge (2010) Engineering Structures, 32 (9), pp. 2814-2824; Keller, T., Bai, Y., Vallée, T., Long-term performance of a glass fiber-reinforced polymer truss bridge (2007) Journal of Composites for Construction, 11 (1), pp. 99-108; Kostopoulos, V., Markopoulos, Y.P., Vlachos, D.E., Design and construction of a vehicular bridge made of glass/polyester pultruded box girders (2005) Plastics Rubber and Composites, 34 (4), pp. 201-207; Lee, C., Sam, L., Development of FRP bridges in the UK – an overview (2010) Advances in Structural Engineering, 13, pp. 5823-5835; Li, F., Zhang, D.D., Zhao, Q.L., A simple analytical solution for predicting deflection of a hybrid FRP-aluminum modular space truss bridge (2015) Journal of Central South University, 22 (11), pp. 4414-4425; Qin, J., Chen, X., Xu, R., Design and experimental study on the joints of nation gymnasium (2007) Industrial Construction, 37 (1), pp. 12-15; Robinson, M.J., Kosmatka, J.B., Development of a short-span fiber-reinforced composite bridge for emergency response and military applications (2008) Journal of Bridge Engineering, 13 (4), pp. 388-397; Roik, K., Composite road and railway bridges in Germany (2011) Composite Construction in Steel and Concrete, pp. 286-301. , Leon R.T., (ed), New York, ASCE, In:, (eds; Ruiz-Teran, A.M., Aparicio, A.C., Structural behaviour and design criteria of under-deck cable-stayed bridges and combined cable-stayed bridges.

Based on Rules for The Classification of Trimarans, seven structural strength checking conditions are designed. Stress distribution of trimaran bulkhead structure and reinforcement before and after optimization under different conditions are calculated by using finite element method and variable density topology optimization method. The results show that: The maximum stress distribution area of bulkhead and reinforcement occurs near the connecting bridge and the large opening. When the volume constraints are changed, the stress distribution and maximum stress of the optimized bulkhead and reinforcement will change accordingly. There is no positive correlation between the maximum stress and the volume reduction ratio of reinforcement. The maximum bulkhead stress cannot be reduced by increasing the volume retention ratio of the reinforcement. The distribution of the optimized reinforcement is similar to that of the real bulkhead. On the premise that the bulkhead has sufficient structural strength, the lightweight design of trimaran structure can be realized based on the topological optimization method. © 2019 Elsevier Ltd","Bulkhead reinforcement; Finite element method; Lightweight design; Topology optimization; Trimaran","Bulkheads (retaining walls); Design; Finite element method; Reinforcement; Strength of materials; Stress concentration; Topology; Lightweight design; Positive correlations; Structural strength; Topological optimization; Topology Optimization Method; Trimaran; Volume constraint; Volume reductions; Shape optimization; design method; finite element method; optimization; reinforcement; ship design; strength; structural analysis; topology",,,,,,,,,,,,,,,,"Allaire, G., Jouve, F., Toader, A.M., A level-set method for shape optimization (2002) Compt.

The finite element method has been broadly used for more than three decades to model the different components of the railroad system such as rails, sleepers (cross ties), and substructure and has been used to investigate a variety of problems associated with rail mechanics. Different multibody systems dynamics software programs have also been developed to investigate the dynamic performance and contact behaviour between the rails and the wheels and to determine the contact forces. In this work, a full three-dimensional model that couples both the finite element method and the multibody systems dynamics has been used to study the railroad system. The main focus of this study is to model the bridge approach problem under dynamic load. The bridge approach problem arises from the sudden change in the foundation's stiffness under the rails at the bridge entry and exit, leading to high levels of stress and settlement that can also cause further problems over time. The effect of using a concrete slab at the bridge entry is also investigated in this study, using two slab designs: rectangular and inclined. The results show the effectiveness of the three-dimensional model and slab implementation on the forces and the vertical deformation, especially the inclined slab that applies a gradual change in the stiffness rather than a sudden change. © IMechE 2019.","bridge approach; finite element method; modal analysis; multibody dynamics; Train–track–soil model","Bridge approaches; Concrete slabs; Dynamic loads; Dynamics; Modal analysis; Railroad plant and structures; Railroads; Stiffness; Dynamic performance; Full three-dimensional; Multi-body dynamic; Multi-body systems dynamics; Software program; Soil model; Three-dimensional model; Vertical deformation; Finite element method",,,,,"U.S. Department of Transportation, DOT: University Transportation Center","The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This project was supported by the National University Rail (NURail) Center – a US DOT OST-R University Transportation Center.",,,,,,,,,,"Xiao, X.B., Wen, Z.F., Jin, X.S., Effects of track support failures on dynamic response of high speed tracks (2007) Int J Nonlinear Sci Numer Simul, 8, pp. 615-630; Xiao, X., Jin, X., Deng, Y., Effect of curved track support failure on vehicle derailment (2008) Vehicle Syst Dyn, 46, pp. 1029-1059; Chebli, H., Clouteau, D., Schmitt, L., Dynamic response of high-speed ballasted railway tracks: 3d periodic model and in situ measurements (2008) Soil Dyn Earthquake Eng, 28, pp. 118-131; Kumaran, G., Menon, D., Krishnan Nair, K., Dynamic studies of railtrack sleepers in a track structure system (2003) J Sound Vib, 268, pp. 485-501; Koskinen, M., Modeling of soil-structure interaction between railway bridge and soil (2005) ABAQUS Users' Conference; Tutumluer, E., Huang, H., Hashash, Y.M.A., Discrete element modeling of railroad ballast settlement (2007) AREMA Conference; Wu, Y.S., Yang, Y.B., Yau, J.D., Three-dimensional analysis of train-rail-bridge interaction problems (2001) Vehicle Syst Dyn, 36, pp. 1-35; Shabana, A.A., Tobaa, M., Sugiyama, H., On the computer formulations of the wheel/rail contact problem (2005) Nonlinear Dyn, 40, pp. 169-193; Shabana, A.A., Sany, J.R., A survey of rail vehicle track simulations and flexible multibody dynamics (2001) Nonlinear Dyn, 26, pp. 179-212; Galvín, P., Romero, A., Domínguez, J., Fully three-dimensional analysis of high-speed train–track–soil-structure dynamic interaction (2010) J Sound Vib, 329, pp. 5147-5163; Tanabe, M., Wakui, H., Sogabe, M., A combined multibody and finite element approach for dynamic interaction analysis of high-speed train and railway structure including post-derailment behavior during an earthquake (2010) IOP Conf Ser Mater Sci Eng, 10, p. 012144; Ambrósio, J., Pombo, J., Rauter, F., A memory based communication in the co-simulation of multibody and finite element codes for pantograph-catenary interaction simulation (2009) In: Bottasso CL (ed.)Multibody dynamics: computational methods and applications, pp. 231-252. , Dordrecht, Springer; El-Ghandour, A.I., Hamper, M.B., Foster, C.D., Coupled finite element and multibody system dynamics modeling of a three-dimensional railroad system (2016) Proc IMechE, Part F: J Rail and Rapid Transit, 230, pp. 283-294; Briaud, J.L., James, R.W., Hoffman, S.B., (1997) Settlement of bridge approaches: (the bump at the end of the bridge), vol 234. , Washington, DC, National Academy Press; Monley, G., Wu, J., Tensile reinforcement effects on bridge approach settlement (1993) J Geotech Eng, 119, pp. 749-762; Helwany, S.M.B., Wu, J.T.H., Froessl, B., GRS bridge abutments – an effective means to alleviate bridge approach settlement (2003) Geotext Geomembr, 21, pp. 177-196; Li, D., Davis, D., Transition of railroad bridge approaches (2005) J Geotech Geoenviron Eng, 131, pp. 1392-1398; Dahlberg, T., Railway track stiffness variations consequences and countermeasures (2010) Int J Civil Eng, 8, pp. 1-12; Zhang, J., Zheng, J.J., Lu, Y., Evaluation of the new technique of geogrid-reinforced and pile-supported embankment at bridge approach (2014) J Bridge Eng, 19, p. 06014001; Paixao, A., Fortunato, E., Calada, R., Design and construction of backfills for railway track transition zones.

Ultrasonic horn is the core component of ultrasonic equipment, which has an important influence on ultrasonic equipment. The traditional design of ultrasonic horn is designed by the traditional analytical method, and then revised repeatedly to guide the application requirements.

It consists of a silicon membrane and transistors, which are designed and manufactured using 1.0 μm-XC10 technology from X-Fab. The transducers for sensing mechanical stress are placed on the edges with the maximum stress. Furthermore, the position is optimized by using FEM simulations (Ansys). Different variances of transistors and the impact on their electrical properties are investigated. Transistors are manufactured with different parameters such as channel lengths, widths, and alignments of the channel current to the direction of the mechanical stress, as well as connecting transistors in Wheatstone-like quarter and half bridges to generate a read-out voltage that is amplified using an integrated operational amplifier on the same chip. The bridge consists of p-MOSFETs as transducers on the membrane and n-MOSFETs as reference transistors (active loads). Transistors bridges are optimized on sensitivity, linearity and temperature behavior by varying channel length (L) and width (W). The influence of the membrane size and deposited technology layers is also investigated. The focus of this publication is presenting an analysis of the electrical behavior of the designed and manufactured transistors for different applied pressures. An experimental setup with a temperature and pressure calibrators is used for characterizing the transducers between 25 and 75 °C and up to 1 bar differential pressure. © 2018 WILEY-VCH Verlag GmbH & Co.

Its construction technology has been inscribed on the List of Intangible Cultural Heritage in Need of Urgent Protection by UNESCO in 2009, and twenty-two bridges of this kind have been listed in the tentative list of the Chinese World Cultural Heritage since 2012. Made by longitudinal and transverse straight logs woven together with mortises and tenon joints, the main arch is not a planar structure nor a general three-dimensional spatial one, and its mechanical behavior cannot be computed by the traditional structural analysis method. In this study, loading tests and FE analyses on the woven arch, and field tests and FE analyses on a really bridge are carried out. For the woven arch, two joint types, rigid and hinged joints are considered in the tests and analyses. The results show that: (1) the deflection shapes of woven arch models with rigid joints and hinged joints are similar; (2) the deflection of a hinged woven arch is larger than that of a rigid one; (3) the two systems of a woven arch can work together simply by the contact between them, but in some loading cases, some portions of them will separate and no force is transferred between them; (4) the mechanical behavior of the woven arch is similar to that of the two-hinged arch. In other words, it is also subjected to horizontal thrusts under vertical loads, but the compression force is the dominant one; and (5) the modeling method of the woven arch is applicable to Chinese timber arch bridges. © 2019 Elsevier Ltd","Deformation; Dual system; Field test; Internal force; Mechanical behavior; Two-hinged arch; Woven timber arch","Arches; Deformation; Timber; Weaving; Dual system; Field test; Hinged arches; Internal forces; Mechanical behavior; Arch bridges; bridge; deformation; finite element method; force; heritage conservation; loading test; mechanical property; timber",,,,,"2017I0009; National Natural Science Foundation of China, NSFC: 51408129","The authors would like to express their sincere gratitude to National Natural Science Foundation of China (No. 51408129 ), and the foreign cooperation projects of science and technology agency in Fujian Province (No. 2017I0009 ) for providing the necessary funds for this research work.",,,,,,,,,,"Knapp, R.G., Peter Bol, A., Ong, C., Bridges, C., Living architecture from China's past (2008), Tuttle Publishing America; Yang, Y., Nakamura, S., Chen, B., Nishikawa, T., A survey on existing China timber arch bridges (2012) Journal of Civil Structure and Material, 28, pp. 61-68. , Kyushu Association for Bridge and Structural Engineering (KABSE); Tang, H., China ancient bridges (1987), Cultural Relics Publishing House Beijing [in Chinese]; Tang, H., History of science and technology of China: bridge volume (2000), Science Publishing House [in Chinese]; Yang, Y., Chen, B., Gao, J., Timber Arch Bridges in China (2007) Proceedings of the fifth international conference on Arch Bridge, Portugal, Sept 12–14, 2007, pp. 171-178; Yang, Y., Nakamura, S., Chen, B., Nishikawa, T., The origin of timber Arch Bridges in China (2014) J JSCE (Jpn Soc Civil Eng), 2, pp. 54-61; Ceraldi, C., Ermolli, E.R., (2004) Timber Arch Bridges: a Design by Leonardo.

Impact of five types of imperfections most frequently encountered in experimental practice and the resulting errors in the position of the specimen in relation to the axis of the bars on the reflected and the transmitted wave profile and on the shape of the stress-strain curve was analysed. The problem was considered based on numerical analyses using a finite element method. It was found that imperfections disturb mainly the beginning and end portions of the reflected and transmitted pulses, which is reflected in the stress-strain curve profile. However, for ductile materials, influence of specimen geometrical imperfections is small, and therefore the SHPB experiments results can be considered reliable from a practical point of view. In the case of all the analysed imperfections, it can be assumed that for imperfection angles α ≤ 0.3°, errors in determination of the stress-strain curves can be omitted. © 2018, The Author(s).","High-strain-rate testing; Numerical simulation; Specimen geometrical imperfection; Split Hopkinson pressure bar","Bridge decks; Computer simulation; Ductility; Geometry; Mechanical testing; Numerical methods; Strain rate; Ductile materials; Geometrical imperfections; High strain-rate testing; Sample geometry; Specimen geometry; Split Hopkinson pressure bars; Transmitted pulse; Transmitted waves; Stress-strain curves",,,,,"Wojskowa Akademia Techniczna: PBS 23-937","The support from the Military University of Technology grant PBS 23-937 is gratefully acknowledged.",,,,,,,,,,"Chen, W., Song, B., (2011) Split Hopkinson (Kolsky) bar: design, testing and applications, , Springer, Berlin; Follansbee, P.S., The Hopkinson bar in mechanical testing (1985) ASM handbook vol 8 9th edn, mechanical testing, pp. 198-217. , Newby JR, (ed), ASM International, Metals Park; Frantz, C.E., Follansbee, P.S., (1984) Experimental techniques with the split Hopkinson pressure bar, pp. 229-236. , Press Vessel and Piping Div, ASME, San Antonio; Lu, Y.B., Li, Q.M., Appraisal of pulse-shaping technique in Split Hopkinson pressure bar tests for brittle materials (2010) Int J Prot Struct, , (,),.,., https://doi.org/10.1260/2041-4196.1.3.363; Bekker, A., Cloete, T.J., Chinsamy-Turan, A., Constant strain rate compression of bovine cortical bone on the split-Hopkinson pressure bar (2015) Mater Sci Eng C, 46, pp. 443-449; Kariem, M.A., Beynon, J.H., Ruan, D., Misalignment effect in the split Hopkinson pressure bar technique (2012) Int J Impact Eng, 47, pp. 60-70; Gray, G.T., III, Classic split-Hopkinson pressure bar technique (2000) ASM handbook, mechanical testing and evaluation vol. 8, , Kuhn H, Medli(eds), ASM International, Metals Park; Owens, A.T., Tippur, H.V., A tensile split Hopkinson bar for testing particulate polymer composites under elevated rates of loading (2008) Exp Mech, 49, pp. 799-811; Field, J.E., Walley, S.M., Proud, W.G., Goldrein, H.T., Siviour, C.R., Review of experimental techniques for high rate deformation and shock studies (2004) Int J Impact Eng, 30, pp. 725-775; Cadoni, E., Solomos, G., Albertini, C., Mechanical characterization of concrete in tension and compression at high strain rate using a modified Hopkinson bar (2009) Mag Concr Res, 61, pp. 221-228; Gerlach, R., Kettenbeil, C., Petrinic, N., A new split Hopkinson tensile bar design (2012) Int J Impact Eng, 50, pp. 63-67; Mohr, D., Gary, G., M-shaped specimen for the high-strain rate tensile testing using a split Hopkinson pressure bar apparatus (2007) Exp Mech, 47, pp. 681-692; Panowicz, R., Janiszewski, J., Traczyk, M., Strain measuring accuracy with splitting-beam laser extensometer technique at split Hopkinson compression bar experiment (2017) Bull Pol Ac Tech, , https://doi.org/doi.https://doi.org/10.1515/bpasts-2017-0020; Panowicz, R., Analysis of selected contact algorithms types in terms of their parameters selection (2013) J KONES Powertrain Transp, 20, pp. 263-268; Hallquist, J.O., (2006) Ls-Dyna.

The results obtained show that, compared with the stress response of a fixed node at the midspan, the response of stress extremes of the BDP not only reflect the stochastic characters of vehicle loads but also directly reflect the most disadvantageous response of the structure. In addition, it was found that the amplification coefficients of different control stresses were very close for a certain international roughness index, the stress response of the BDP considering roughness was significantly greater than that of smooth surfacing and when vehicles are travelling on a bridge with a rough surface, speed should be controlled to be neither too fast nor too slow. © ICE Publishing: All rights reserved.","bridges; dynamics; pavement design","Bridge decks; Bridges; Dynamic response; Dynamics; Pavements; Stochastic systems; Surface roughness; Vehicles; Amplification coefficient; Bridge deck pavements; Coupling vibration; International roughness index; Pavement design; Three dimensional finite elements; Vehicle bridges; Vehicle velocity; Vibrations (mechanical); bridge; design; dynamic analysis; dynamic response; finite element method; loading; pavement; surface roughness; three-dimensional modeling; vibration",,,,,"National High-tech Research and Development Program: 2014AA110402; National Key Research and Development Program of China, NKRDPC: 2017YFF0205605","This work was supported by the National Key R&D Program of China (2017YFF0205605), State High-Tech Research and Development Plans (863) (2014AA110402), the Shanghai Urban Construction Design Research Institute project ‘Bridge safe operation big data acquisition technology and structure monitoring system research’ and the Ministry of Transport Construction Science and Technology project ‘Medium–small span bridge structure network level safety monitoring and evaluation’.",,,,,,,,,,"Bilodeau, J.P., Gagnon, L., Doré, G., Assessment of the relationship between the international roughness index and dynamic loading of heavy vehicles (2017) International Journal of Pavement Engineering, 18 (8), pp. 693-701; Bocci, E., Canestrari, F., Analysis of structural compatibility at interface between asphalt concrete pavements and orthotropic steel deck surfaces (2012) Transportation Research Record, 2293, pp. 1-7; Bocci, E., Canestrari, F., Experimental evaluation of the mechanical contribution of two special materials (or techniques) to the shear resistance of steel-asphalt interfaces (2013) Transportation Research Record, 2370, pp. 145-150; Bryce, J., Rada, G., Thyagarajan, S., Sivaneswaran, N., Validation of the pavement remaining service interval concept using highway agency models and data (2017) Proceedings of the World Conference on Pavement and Asset Management, , Milan, Italy; (2004) JTG D60-2004 General Code for Design of Highway Bridges and Culverts, , CCCC Highway Consultants Co., Ltd.China Communications Press, Beijing, China; Chen, T.T., Factors in bridge failure, inspection, and maintenance (2017) Journal of Performance of Constructed Facilities, 31 (5), p. 04017070; Cheng, Y., Cheung, K., Effects of random road surface roughness and long-term deflection of prestressed concrete girder and cable-stayed bridges on impact due to moving vehicles (2001) Computers and Mechanics, 79 (8), pp. 853-872; Da, W., Han, W.S., Huang, P.M., Jian, L., Influence of bridge surface roughness on vehicle-bridge coupled vibration of long-span suspension bridge (2009) Journal of Changan University, 29 (4), pp. 53-58; Duan, M.H., Shi, F., Xie, F., Zhang, K.B., A survey of road roughness study (2009) Journal of Vibration and Shock, 28 (9), pp. 95-101; Hammarström, H., Karlsson, R., Sörensen, H., Yahya, M.R., (2012) Coastdown Measurement with 60-tonne Truck and Trailer: Estimation of Transmission, Rolling and Air Resistance, , Vti Notat, Linköping, Sweden; Hassan, R., Evans, R., Road roughness characteristics in car and truck wheel tracks (2013) International Journal of Pavement Engineering, 14 (8), pp. 736-745; Huston, D., Cui, J., Burns, D., Hurley, D., Concrete bridge deck condition assessment with automated multisensory techniques (2011) Structure and Infrastructure Engineering, 7 (7-8), pp. 613-623; Kargah-Ostadi, N., Stoffels, S.M., Tabatabaee, N., Network-level pavement roughness prediction model for rehabilitation recommendation (2010) Transportation Research Record, 2155, pp. 124-133; Li, J.H., He, J., Li, X.H., Dynamic response of pavement under vehicle random load and moving constant load (2015) Journal of Changan University, 35 (2), pp. 38-45; Lu, P., Tolliver, D., Pavement pre-and post-treatment performance models using LTPP data (2013) Journal of the Transportation Research Forum, 51 (3), pp. 67-81; Paterson, W.D., Watanatada, T., Relationships between vehicle speed, ride quality, and road roughness (1985) Measuring Road Roughness and Its Effects on User Cost and Comfort, pp. 89-110. , (Gillespie TD and Sayers M (eds)).

Due to the overestimation of the capacity of the cylindrical specimens, segment specimens were designed to investigate the mechanical behavior of large-diameter grouted connections. A test program involving 10 specimens was executed to explore the behavior of grouted connection when subjected to lateral pressure and vertical loads. The test parameters include grout thickness, lateral pressure, and shear key spacing. The number of shear keys were also considered. The failure modes, bearing capacity and longitudinal strain distribution of grouted connections are studied. Test results showed that all tested specimens failed in a ductile way and diagonal cracks between shear keys were observed in the final failure modes. In addition, the nonlinear finite element analysis (FEA) models were established to predict the behavior of grouted connections. The concrete damaged plasticity model available in ABAQUS was adopted, and the FEA models were verified using the test results. An extensive parametric study was conducted to identify the effect of steel yield strength, grout compressive strength, lateral pressure, grout thickness, shear key spacing, and the thickness of steel plates on the bearing capacity of grouted connections. Results indicated that the bearing capacity increased with the lateral pressure or grout compressive strength but decreased with the grout thickness. © 2019 Elsevier Ltd","Grout thickness; Grouted connections; Lateral pressure; Numerical analysis; Shear keys","ABAQUS; Bearing capacity; Bridge decks; Compressive strength; Concrete construction; Grouting; Numerical analysis; Offshore oil well production; Offshore wind turbines; Shear flow; Software testing; Strain; Cylindrical specimens; Damaged plasticities; Grouted connection; Lateral pressures; Longitudinal strain; Mechanical behavior; Nonlinear finite element analyses (FEA); Shear key; Mortar",,,,,"2017YFC1500704","This project was supported by the National Key R&D Program of China ( 2017YFC1500704 ).

According to the magnetic field distribution, the iron cores are divided into tooth, yoke, bridge, and shoe. Based on the boundary conditions of the subdomain model, the bridge is equivalent to the fan-shaped region with constant permeability. Then, the no-load and on-load magnetic fields in the air gap, tooth, yoke, bridge, and shoe are analytically calculated. The impacts of slotting and bridge saturation are considered. On the basis of the analytical expression of the magnetic fields, the iron losses of the tooth, yoke, bridge, and shoe are obtained by the Bertotti model. The analytical results in the no-load and on-load conditions are compared with that of the finite-element analysis. The validity is verified by the finite-element analysis. © 1965-2012 IEEE.","Analytical calculation; bridge saturation; iron losses; magnetic field distribution (MFD); spoke-type permanent magnet synchronous in-wheel motor (STPMSIWM)","Electric losses; Electric machine theory; Iron; Magnetic fields; Permanent magnets; Traction motors; Wheels; Analytical calculation; Analytical expressions; Analytical results; Constant permeabilities; In-wheel motor; Iron loss; Magnetic field distribution; Permanent magnet synchronous; Finite element method",,,,,"Fundamental Research Funds for the Central Universities: 31020180QD137","ACKNOWLEDGMENT This work was supported by the Fundamental Research Funds for the Central Universities under Grant 31020180QD137.",,,,,,,,,,"Jaguemont, J., Boulon, L., Dubé, Y., Martel, F., Thermal management of a hybrid electric vehicle in cold weather (2016) IEEE Trans.

Cracking is one of the main distresses for a reinforced concrete (RC) bridge, which also reduces the safety and service life of the structure. The existing calculation methods of crack width, which are used to evaluate the crack width induced by the external loads, are not suitable to calculate the early-age crack width. To evaluate the early-age crack width, a calculation method of early-age crack width was presented. The finite element analysis (FEA) model of the PC box girder being built was used to analyze two affecting parameters of early-age cracking by ABAQUS 2017 program. Through the nonlinear FEA model of the PC box girder, the calculation formula of early-age crack width was used to evaluate the crack width. The validity of the nonlinear FEA method has been verified by comparing the simulation results with the measured results. © 2019, Korean Society of Civil Engineers.","calculation method of crack width; concrete placement; early-age cracking; finite element analysis; hydration heat effect; reinforced concrete bridge; shrinkage effect","ABAQUS; Box girder bridges; Cast in place concrete; Concrete bridges; Concrete placing; Nonlinear analysis; Prestressed concrete; Railroad bridges; Reinforced concrete; Shrinkage; Concrete placement; Crack width; Early age cracking; Hydration heat; Shrinkage effects; Finite element method",,,,,,,,,,,,,,,,"Bernardi, P., Ferretti, D., Michelini, E., Sirico, A., Evaluation of crack width in RC ties through a numerical “range” model (2016) Procedia Structural Integrity, 2 (2), pp. 2780-2787; Chen, M., Zhang, T.J., Lu, Y.M., Xing, G., Comparative study on several shrinkage formulas of commercial concrete (2004) Buildings of Posts and Telecommunications, 6, pp. 53-56; Elnashai, A.S., Di Sarno, L., (2008) Fundamentals of earthquake engineering, , John Wiley & Sons Ltd., Chichester, UK; ElSafty, A., Abdel-Mohti, A., Jackson, M., Lasa, I., Paredes, M., Limiting early-age cracking in concrete bridge decks (2013) Advances in Civil Engineering Materials, 2 (1), pp. 379-399; ElSafty, A., Graeff, M.K., El-Gharib, G., Abdel-Mohti, A., Jackson, N.M., Analysis, prediction, and case studies of early-age cracking in bridge decks (2016) International Journal of Advanced Structural Engineering, 8 (2), pp. 193-212; (2005) Eurocode 2: Design of concrete structures—Concrete bridges—Design and detailing rules buildings, , EN 1992–2, EN 1992–2:2005, European Committee for Standardization, Brussel, Belgium; (2009) Code for Construction of Mass Concrete, , GB 50496–2009, China National Standards GB 50496–2009, Ministry of Housing and Urban-Rural Development of the People’s Republic of China, Beijing, China; Ghatefar, A., El-Salakawy, E., Bassuoni, M.T., Early-age restrained shrinkage cracking of gfrp-rc bridge deck slabs: Effect of environmental conditions (2015) Cement & Concrete Composites, 64 (11), pp. 62-73; Gilbert, R.I., Cracking caused by early-age deformation of concrete–prediction and control (2017) Procedia Engineering, 172 (3), pp. 13-22; Hendy, C.R., Smith, D.A., (2007) Designers’ guide to EN 1992–2.

The existing procedures for structural assessment often under-estimate the load capacity of bridge deck slabs and therefore further investigation is needed to check if enhanced methods are more accurate. The aim of this study was to investigate the effect of redistribution of shear forces on the load-carrying capacity of cantilever bridge deck slabs subjected to concentrated loads. A Multi-level Assessment Strategy including analytical structural analysis methods as well as linear and non-linear FE methods was adopted. The study also aimed at understanding the effect of some geometric and support parameters on the structural response of the bridge deck slabs. The parameter study, including the influence of support stiffness, effective depth, reinforcement ratio and edge beams, helped to understand their impact on the load distribution, load-carrying capacity and failure modes. A new method for determining the effective width for one-way shear based on the nonlinear analysis and experimental evidence was proposed. © 2019 Elsevier Ltd","Cantilever slabs; FE analysis; Load distribution; Multi-level assessment; One-way shear","Bridge decks; Electric power plant loads; Load limits; Nanocantilevers; Nonlinear analysis; Shear flow; Structural analysis; Cantilever slabs; Experimental evidence; FE analysis; Load distributions; Multi-level assessment; Reinforcement ratios; Structural assessments; Structural response; Loads (forces); bridge; carrying capacity; finite element method; reinforced concrete; stiffness",,,,,"Chalmers Tekniska Högskola; Syddansk Universitet, SDU; Trafikverket","The authors would like to gratefully acknowledge the support and funding from the Swedish Transport Administration (Trafikverket).

This article aims to better understand the influencing factors of stress distribution on the steel shims and the effect of steel shim thickness on the critical behaviour of elastomeric bearings. First, theoretical analysis is conducted for investigating the influencing factors of the bearing’s critical load capacity and stress distribution on the steel shim thickness. Then, a series of finite element models is employed to study the influence of steel shim thickness on the global performance of bearings, the stress distribution on steel shims at different locations and the effect of steel shim thickness on stress distribution. Combining the results of theoretical analysis and finite element analysis, we conclude that steel shim thickness has little obvious effect on the mechanical properties of the bearing under normal working conditions, but it has a significant influence on the distribution and change of the local stress. Especially, when the vertical load and the horizontal displacement of the bearing increases, the growth rate of stress on the upper steel shims is very fast and may enter the yield state first or even resulting in local damage. © The Author(s) 2019.","elastomeric bearing; finite element analysis; horizontal displacement; steel shim thickness; stress distribution","Bearings (machine parts); Bridge bearings; Finite element method; Seismic design; Stress concentration; Thermoelectricity; Critical behaviour; Effect of parameters; Elastomeric bearing; Finite-element study; Global performance; Horizontal displacements; Seismic isolation devices; Vertical load; Shims",,,,,"2017YFC0703600","The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This research was supported by the National Key R&D Program of China (no. 2017YFC0703600).",,,,,,,,,,"(2008) Abaqus Analysis User Manual Version 6.8, , Providence, RI, Dassault Systèmes Simulia Corp; Bergström, J.S., Boyce, M.C., Constitutive modeling of the large strain time dependent behavior of elastomers (1998) Journal of the Mechanics and Physics Solids, 46, pp. 931-954; Buckle, I., Nagarajaiah, S., Ferrell, K., Stability of elastomeric isolation bearings: experimental study (2002) Journal of Structural Engineering-ASCE, 128 (1), pp. 3-11; Buckle, I.G., Kelly, J.M., Properties of slender elastomeric isolation bearings during shake table studies of a large-scale model bridge deck (1986) Joint Sealing and Bearing Systems for Concrete Structures (ACI), 1, pp. 247-269; Buckle, I.G., Liu, H., (1993) Stability of elastomeric seismic isolation systems, , ATC Seminar on Seismic Isolation, Passive Energy Dissipation and Control, San Francisco, CA, 11–12, March, Redwood City, CA, Alied Technology Council, In; Cardone, D., Perrone, G., Critical load of slender elastomeric seismic isolators: an experimental perspective (2012) Engineering Structures, 40, pp. 198-204; Chalhoub, M.S., Kelly, J.M., Effect of compressibility on the stiffness of cylindrical base isolation bearings (1990) International Journal of Solids and Structures, 26 (7), pp. 743-760; Forcellini, D., Mitoulis, S.A., Kalfas, K., (2017) Study on the response of elastomeric bearings with 3D numerical simulations and experimental validation, , COMPDYN 2017; 6th International Conference on Computational Methods Structural Dynamics and Earthquake Engineering, Rhodes, Greece, 15–17 June, In; Han, X., Warn, G.P., Mechanistic model for simulating critical behavior in elastomeric bearings (2014) Journal of Structural Engineering, 139 (12), p. 04014140; Imbimbo, M., Kelly, J.M., Stability of isolators at large horizontal displacements (1997) Earthquake Spectra, 13, pp. 415-430; Kalfas, K., Mitoulis, S.A., Performance of steel-laminated rubber bearings subjected to combinations of axial loads and shear strains (2017) Procedia Engineering, 199, pp. 2979-2984; Kalfas, K.N., Mitoulis, S., Katakalos, K., Numerical study on the response of steel-laminated elastomeric bearings subjected to variable axial loads and development of local tensile stresses (2017) Engineering Structures, 134, pp. 346-357; Kelly, J.M., Konstantinidis, D.A., Steel shim stresses in multilayer bearings under compression and bending (2009) Journal of Mechanics of Materials and Structures, 6 (4), pp. 1109-1125; Koh, C.G., Kelly, J.M., (1987) Effects of axial load on elastomeric bearings, , Berkeley, University of California, Earthquake Engineering Research Center Report no.

In order to avoid such clinical complications, the implant stiffness needs to be appropriately adapted. In this study, hollow channels were virtually introduced within the designed implant screws for reduction of the overall stiffness of the prototype. In particular, two opposing radial gradients of increasing hollow channel diameters, i.e., outside to inside (Channel 1) and inside to outside (Channel 2) were considered. Two clinical situations of edentulism were addressed in this finite element-based study, and these include a) loss of the first molar, and b) loss of all the three molars. Consequently, two implantation approaches were simulated for multiple teeth loss - individual implantation and implant supported dental bridge. The effects of implant length, approach and channel distribution on the biomechanical response were evaluated in terms of the von Mises stress within the interfacial periprosthetic bone, under normal masticatory loading. The results of our FE analysis clearly reveal significant variation in periprosthetic bone stress between the different implant designs and approaches. An implant screw length of 11 mm with the Channel 2 configuration was found to provide the best biomechanical response. This study also revealed that the implant supported dental bridge approach, which requires lower bone invasion, results in favorable biomechanical response in case of consecutive multiple dental loss. © 2019 Elsevier Ltd","Dental bridge; Finite element; Implant; Stress/strain","Biomechanics; Bone; Finite element method; Implants (surgical); Screws; Stiffness; Stress analysis; Biomechanical response; Channel distributions; Clinical complications; Clinical situations; Functional gradation; Implant loosening; Overall stiffness; Stress/strain; Dental prostheses; Article; biomechanics; bone density; bone remodeling; bone stress; controlled study; finite element analysis; first molar; mastication; osseointegration; periodontal disease; porosity; priority journal; prosthesis design; temporomandibular joint; third molar; tooth implantation; von Mises stress; biomechanics; diagnostic imaging; human; mechanics; molar tooth; periodontal disease; tooth implant; x-ray computed tomography; Biomechanical Phenomena; Dental Implants; Finite Element Analysis; Humans; Mechanical Phenomena; Molar; Porosity; Tomography, X-Ray Computed; Tooth Loss",,"Dental Implants",,,"DSTO1303; Science and Engineering Research Board, SERB; Department of Science and Technology, Government of Rajasthan, DST; Department of Biotechnology, Government of West Bengal, DBT-WB: DBTO0455","The authors thank “Translational Center on Biomaterials for orthopaedic and dental applications” sponsored by Department of Biotechnology (DBT), Govt. of India.

It is important to analyze and understand the evolution rule of circular saw blade's dynamic characteristics after laser shock tensioning process. Therefore, for a more systematic study of laser shock tensioning process, a theoretical model for tensioning stress field and natural frequency was built based on finite element method, reasonable simplifications and assumptions. By comparing theoretical analysis and measured results, the theoretical model was proved to be correct. Theoretical analysis results show that beneficial tangential tensile tensioning stress with a certain value is produced in the outer edge of circular saw blade after laser shock tensioning process. Natural frequencies of circular saw blade for nodal circle Nc = 0 and nodal diameter Nd ≥ 2 are increased obviously with impact zone radius and peak pressure of laser shock wave, which means that the dynamic stability of circular saw blade is improved after laser shock tensioning process. © 2019 Elsevier Ltd","Circular saw blade; Laser shock; Natural frequency; Stress; Tensioning","Bridge cables; Computational efficiency; Metal working saws; Natural frequencies; Sawing; Shock waves; Stresses; Circular saw blade; Dynamic characteristics; Finite element simulations; Laser shock waves; Laser shocks; Tensioning; Tensioning process; Theoretical modeling; Finite element method",,,,,"National Natural Science Foundation of China, NSFC: 31600458; Fundamental Research Funds for the Central Universities: CAFYBB2017SY039, CAFYBB2019QB006","We gratefully acknowledge the financial support of Fundamental Research Funds for the Central Non-profit Research Institution of CAF (No. CAFYBB2017SY039 and CAFYBB2019QB006 ) and National Natural Science Foundation of China (No. 31600458 ).",,,,,,,,,,"Li, S., Wang, C., Zheng, L., Wang, Y., Xu, X., Feng, D., Dynamic stability of cemented carbide circular saw blades for woodcutting (2016) J.

Physical reconstructions are often used in concussive research, using the recorded kinematics to load finite element models of the brain to obtain better information of real-life head injuries. For children, scaling adult models is a common method used to study the youth population. However, this method does not capture age-dependent material properties or the unique geometry of the developing brain. To address these deficiencies, a novel three-dimensional finite element model of a 6-year-old child was developed and compared to a scaled adult model, for use with physical reconstructions. With the lack of intracranial validation data for the youth population, adult cadaveric data for brain motion was used for comparison. The new brain model showed unique responses in motion and strain compared to the scaled adult model. Using the normalized integral square error method, the new model was classified to have ‘fair’ to ‘excellent’ biofidelity. The new model is proposed as more appropriate for conducting concussion and brain injury research in young children near 6 years of age. © IMechE 2019.","biomechanics; brain injury; child; concussion; Finite element modelling; head impact","Biomechanics; Brain models; Composite bridges; Population statistics; Repair; Three dimensional computer graphics; Brain injury; child; concussion; Finite element modelling; Head impact; Finite element method",,,,,"National Operating Committee on Standards for Athletic Equipment, NOCSAE; Natural Sciences and Engineering Research Council of Canada, NSERC","The authors would like to thank the two granting agencies, the Natural Sciences and Engineering Research Council of Canada and the National Operating Committee on Standards for Athletic Equipment.

A nonlinear fiber section element model is constructed in OpenSees to simulate the hysteretic behavior of a UHPSFRC bridge pier. Experimental data from a UHPSFRC column is utilized to verify the accuracy of the nonlinear numerical model. Based on the nonlinear fiber section element model, a new technique of nonlinear finite element model updating involving two updating stages is developed. This new method is designed to incorporate the maximum and minimum strains of section fibers as the updating parameters. By forming the objective function from the modal information, the damage parameters related to the nonlinear material model can be updated by solving the constrained optimization problem. To validate the efficiency of this updating approach, it has been applied to a numerically simulated UHPSFRC pier. With using the updated nonlinear finite element model, the residual axial loading capacity and post-seismic performance of the UHPSFRC pier are examined. The numerical results indicate that the updated nonlinear finite element model can be used not only to assess the current damage state of the UHPSFRC pier but also to predict its future performance after an earthquake. Finally, the noise effect on the proposed method is also investigated. The results reveal that the post-earthquake evaluation approach for UHPSFRC piers based on this study's updating algorithm is robust to noise. © 2019 Elsevier Ltd","Fiber section element model; Finite element model updating; OpenSees; Post-earthquake performance; UHPSFRC pier","Constrained optimization; Earthquakes; Fiber reinforced materials; Hysteresis; Piers; Reinforced concrete; Steel fibers; Constrained optimi-zation problems; Earthquake performance; Element models; Finite-element model updating; Non-linear finite element model; Non-linear numerical model; Nonlinear material models; Opensees; Finite element method",,,,,"Australian Research Council, ARC: DP160104661","The authors would like to acknowledge the financial support from Australian Research Council DP grant DP160104661 .",,,,,,,,,,"Xu, S., Wu, C., Liu, Z., Han, K., Su, Y., Zhao, J., Li, J., Experimental investigation of seismic behavior of ultra-high performance steel fiber reinforced concrete columns (2017) Eng.

Proper pulse shaping is vital for achieving stress equilibrium and a constant strain rate within the dynamically tested sample. A systematic method based on two-dimensional finite element (FE) analysis was developed to design an optimized single material pulse shaper for SHPB testing of two stainless steel alloys. The tested alloys exhibit high strain-hardening, but have significantly different mechanical properties: Lean Duplex Stainless Steel 2101 (LDSS 2101) and austenitic stainless steel 316L. Results show that pulse shapers made of LDSS 2101 are capable of satisfying stress equilibrium and constant strain rate conditions for the studied materials at different strain rates regimes. The outlined FE analysis workflow is an effective approach to define the optimal dimensions of pulse shapers without the need for costly pulse-shaper-development experimental trials. © 2019, Society for Experimental Mechanics, Inc.","Austenitic stainless steel; Finite element analysis; Lean duplex stainless steel; Pulse shaping; Split-hopkinson pressure bar; Strain-hardening","Alloy steel; Austenitic stainless steel; Bridge decks; Duplex stainless steel; Finite element method; Mechanical testing; Nickel steel; Steel testing; Strain hardening; Strain rate; Austenitic stainless; Constant strain rate; Effective approaches; Experimental trials; Integral components; Lean duplex stainless steel; Pulse shaping techniques; Split Hopkinson pressure bars; Pulse shaping",,,,,"Air Force Office of Scientific Research, AFOSR: FA2386-17-1-4095","Acknowledgements Authors would like to thank Mr. Shameem Ahmed at the School of Engineering and Information Technology, UNSW Canberra for providing austenitic stainless steel material 316L.

However, the no-load magnetic coefficient will be increased, which would reduce the utilization rate of the PM. The structure parameters of the rotor should be designed reasonably, especially the bridge. This paper calculates the no-load leakage coefficient by establishing the analytical model of the no-load magnetic coefficient. It shows that, the bridge size has an important effect on the no-load magnetic coefficient. The analysis results are verified by the two-dimensional finite element analysis and tests. © 2019 IEEE.","FSCW; IPMSM; iron bridge; V-type magnets","Bridges; Magnetic leakage; Synchronous motors; Winding; Fractional slot concentrated windings; FSCW; Interior permanent magnet synchronous motor; IPMSM; Leakage coefficient; Permanent magnet motor; Structure parameter; Two-dimensional finite element analysis; Permanent magnets",,,,,"National Natural Science Foundation of China, NSFC: 51577125","Manuscript received July 26, 2018; accepted January 12, 2019.

However, no guidance is given on how to protect these critical elements, nor how to identify them. Further, slender steel web plates have been shown to be vulnerable to shear buckling in fire events and recent research that indicates that the load path of shear forces in thin web plates is not well understood. The overall objective of this paper is to examine the effectiveness of stiffeners for enhancing the shear capacity of slender plates at ambient and elevated temperatures. Specifically, evaluations are made regarding the effectiveness of stiffeners for increasing the shear buckling capacity through various stiffener orientations, providing lateral restraint, and providing a load path for shear forces. In particular, the elastic shear buckling load, Vcr, and the ultimate shear postbuckling load, Vu, of the steel plate are examined. Finite element analyses, which have been validated with experimental data, are used as a basis for the study. The temperatures studied range from ambient to 1100 °C. This study provides some important insights on the behavior of plates under shear loads. For example, results indicate that the stiffener's role is not that of a load path for the shear forces, but one of lateral restraint, regardless of its geometric orientation. Further, it is shown that for lower temperatures a stiffener oriented along the compression diagonal (opposite to a tension field) provides the most improvement in postbuckling strength. © 2018 Elsevier Ltd","Elevated temperature; Plate girder; Postbuckling; Stiffener; Web shear buckling","Beams and girders; Fire hazards; Fire protection; Fires; Plates (structural components); Surface tension; Elevated temperature; Plate girder; Postbuckling; Shear buckling; Stiffener; Loads (forces); buckling; shear; steel; strength; structural component; temperature effect",,,,,"National Science Foundation, NSF: CMMI-1068252; U.S. Department of Defense, DOD; Air Force Office of Scientific Research, AFOSR; National Defense Science and Engineering Graduate, NDSEG: 32 CFR 168a","This research was made with Government support under and awarded by DoD , Air Force Office of Scientific Research , National Defense Science and Engineering Graduate (NDSEG) Fellowship , 32 CFR 168a, provided to Dr. Glassman.

Conversely, since the construction of Musmeci's shell supported bridge in Potenza, few shell bridges have been constructed. This paper explains how to design a curved footbridge supported by an anticlastic shell by shaping the shell via a thrust network analysis (TNA). By taking advantage of the peculiar properties of anticlastic membranes, the unconventional method of shaping a shell by a TNA is illustrated. The shell top edge that supports the deck has an assigned layout, which is provided by the road curved layout. The form of the bottom edge is obtained by the form-finding procedure as a thrust line, by applying the thrust network analysis (TNA) in a non-standard manner, shaping the shell by applying the boundary conditions and allowing relaxation. The influence of the boundary conditions on the bridge shape obtained as an envelope of thrust lines is investigated. A finite element analysis was performed. The results indicate that the obtained shell form is effective in transferring deck loads to foundations via compressive stresses and taking advantage of concrete mechanical properties. © 2018 The Authors","Anticlastic shell; Cantilevered deck; Concrete; Shell footbridges; Thrust network analysis (TNA)","Arch bridges; Boundary conditions; Footbridges; Military operations; Shells (structures); Anticlastic; Cantilevered deck; Concrete mechanical property; Curved bridge; Form finding; Second World War; Supported bridges; Thrust network analysis (TNA); Concretes",,,,,"JA150743; National Natural Science Foundation of China, NSFC: 51508103, 51778148; Fuzhou University, FZU; Recruitment Program of Global Experts: TM2012-27","The research was supported by the Recruitment Program of Global Experts Foundation (Grant No. TM2012-27 ), the National Natural Science Foundation of China (Grant No. 51778148 and 51508103 ) and the Fujian Provincial Education Department Research Foundation for Young Teacher (Grant No. JA150743 ).

The retrofitting technique consists of placing unbonded vertical bars with steel end plates or torque controlled expansion end anchorages in pre-drilled holes of existing thick members. To study the behaviour of these members, loading tests as well as numerical analyses were carried out. Shear capacities were compared to the predictions using the shear design approach in the Canadian Highway Bridge Design Code. The design equations which are intended for traditional stirrups reinforcement overestimates the shear capacities of the members strengthened with unbonded transverse reinforcement. However, numerical analyses provided very accurate predictions of the shear capacities. A finite element parametric study examines the effects of the shear span-to-depth ratio, vertical prestressing, shear reinforcement ratio and the stiffness of the vertical reinforcement. The stiffness of the shear strengthening system and the effects of prestressing significantly affect the shear capacity. The shear capacities were predicted well when a minimum amount of vertical prestressing was provided. © 2018 Elsevier Ltd","Finite element modeling; Reinforced concrete; Shear behaviour; Shear strength; Shear strengthening; Unbonded bars","Bridges; Finite element method; Highway bridges; Highway planning; Numerical analysis; Prestressing; Reinforced concrete; Shear strength; Stiffness; Strengthening (metal); Canadian highway bridge design codes; Shear behaviour; Shear reinforcement; Shear span-to-depth ratios; Shear strengthening; Torque-controlled expansion; Transverse reinforcement; Vertical reinforcement; Shear flow; accuracy assessment; bridge; building code; finite element method; reinforced concrete; shear strength",,,,,"Natural Sciences and Engineering Research Council of Canada, NSERC; Fonds de recherche du Québec – Nature et technologies, FRQNT","The research reported in this paper was made possible by funding from the Natural Sciences and Engineering Research Council of Canada (NSERC, CREATE-INFRA) and the “Fonds de Recherche du Québec – Nature et Technologies” (FRQNT) .

However, fatigue remains as the predominant problem for OSDs. Many researchers have investigated fatigue issues of welded joints through experiments but is not a cost-effective solution. Therefore, it is necessary to combine experimental data with numerical approaches. Fracture mechanics approach has already shown its reliability and can be used to model and analyze fatigue crack propagation. In this paper, a numerical simulation is performed to predict the fatigue crack propagation using extended finite element method (XFEM). Two numerical models were considered namely CT-specimen and OSD, to evaluate the modelling efficiency. To verify the simulation, the results were compared with the experimental data. In predicting the fatigue crack propagation rate using two-dimensional CT-specimen, numerical results provided a good agreement with a maximum difference of 0.03% in the slope (m) and 1.48% in the intercept (C) of the power law equation. Furthermore, a simulation was performed on three-dimensional OSD structure to predict the fatigue crack growth. © 2019 The Authors.","Compact-Tension specimen; Crack propagation; Fatigue; Orthotropic bridge; XFEM",,,,,,,,,,,,,,,,,"Abaqus, V., (2014) 6.14 Documentation., 651. , Dassault Syst Simulia Corp; Bignonnet, A., Carracilli, J., Jacob, B., (1991) ÉTUde en FATIGUE des PONTS MÉTALLIQUES Par un MODELE de MÉCANIQUE de la RUPTURE., , Retrieved from; Bozkurt, F., Schmidová, E., (2018) Fracture Toughness Evaluation of S355 Steel Using Circumferentially Notched Round Bars.; De Backer, H., (2006) Optimalisatie Van Het Vermoeiingsgedrag Van Het Orthotrope Brugdekconcept Door Verbeterde Dispersie Van de Verkeersbelasting, , (in Dutch).

One uniqueness of the handrail energy harvester is that it has two working modes for collecting the energy excited by both vibration and pulling force during the operation. In order to enable good stability and anti-jamming ability for the energy harvester, a compound bridge-type compliant force amplifier is adopted and its parameters are optimized based on multi-objective genetic algorithm with finite-element analysis simulation. Analytical dynamic model is established for the piezoelectric device and the output power is calculated. A prototype harvester is fabricated for experimental investigation. Experimental results verify the effectiveness of the derived analytical model. Moreover, results show that the maximum power output is up to 150μW under vibration excitation and 15 mW under random pulling force input. A series of the designed energy harvesters can be used to scavenge the energy generated by passengers in a bus or subway under different motion states. © 2013 IEEE.","compliant mechanism; dynamics model; Energy harvesting; piezoelectric device; vibration and force input","Compliant mechanisms; Genetic algorithms; Mechanisms; Piezoelectric devices; Piezoelectricity; Railings; Anti-jamming ability; Dynamics modeling; Experimental investigations; Force input; Maximum power output; Multi-objective genetic algorithm; Piezoelectric energy harvesting; Vibration excitation; Energy harvesting",,,,,"MYRG2018-00034-FST, MYRG2019-00133-FST; National Natural Science Foundation of China, NSFC: 51575545; Fundo para o Desenvolvimento das Ciências e da Tecnologia, FDCT: 179/2017/A3","This work was supported in part by the National Natural Science Foundation of China under Grant 51575545, in part by the Macao Science and Technology Development Fund under Grant 179/2017/A3, and in part by the Research Committee of University of Macau under Grant MYRG2018-00034-FST and Grant MYRG2019-00133-FST.",,,,,,,,,,"Shirvanimoghaddam, M., Shirvanimoghaddam, K., Abolhasani, M.M., Farhangi, M., Barsari, V.Z., Liu, H., Dohler, M., Naebe, M., Towards a green and self-powered Internet of Things using piezoelectric energy harvesting (2019) IEEE Access, 7, pp. 94533-94556; Hendrowati, W., Guntur, H.L., Sutantra, I.N., Design, modeling and analysis of implementing a multilayer piezoelectric vibration energy harvesting mechanism in the vehicle suspension (2012) Engineering, 4 (11), p. 728. , Nov; Xie, X., Wang, Q., Energy harvesting from a vehicle suspension system (2015) Energy, 86, pp. 385-392. , Jun; Pellegrini, S.P., Tolou, N., Schenk, M., Herder, J.L., Bistable vibration energy harvesters: Areview (2012) J.

However, their long-term behavior is not well understood, especially in the case of large-span bridges. In order to study the time-dependent performance, a large three-span PC bridge with corrugated steel webbing was compared to a similar conventional PC bridge to examine their respective time-dependent characteristics. In addition, a three-dimensional finite element method with step-by-step time integration that takes into account cantilever construction procedures was used to predict long-term behaviors such as deflection, stress distribution and prestressing loss. These predictions were based upon four well-established empirical creep prediction models. PC bridges with a corrugated steel web were observed to have a better long-term performance relative to conventional PC bridges. In particular, it is noted that the pre-cambering for PC bridges with a corrugated steel web could be smaller than that of conventional PC bridges. The ratio of side-to-mid span has great influence on the long-term deformation of PC bridges with a corrugated steel web, and it is suggested that the design value should be between 0.4 and 0.6. However, the different creep prediction models still showed a weak homogeneity, thus, the further experimental research and the development of health monitoring systems are required to further progress our understanding of the long-term behavior of PC bridges with corrugated steel webbing.

An accurate nonlinear 3D model of the bridge is developed. The elastic properties of the model are calibrated based on both material tests and an experimental campaign carried out for the dynamic identification (in terms of vibration frequencies and modal shapes) via operational modal analysis of the remaining part of the bridge. A numerical simulation of the scour hole progression is performed in order to identify the collapse mechanism of the bridge under the first major flood and estimate the level of scour that caused the bridge failure. © 2019 IABSE.

This paper introduces the possibility to control the fatigue life of existing bridges by using a vibration control system. Based on a dynamic optimization analysis, the stresses from traffic on the bridge are obtained. Subsequently, a plate finite element (FE) model of the whole bridge is developed. The equation of motion is presented for a case study bridge, equipped with different tuned mass damper system, and the combination of external loads and train/track interaction with or without the TMD system is developed through own-developed routines and FEM software. The procedure is showcased for a case study bridge. After gaining the stress states at the critical hotspot, the fatigue crack life is evaluated by using the linear cumulative damage theory. The different TMD solution presented is demonstrated to be able to diminish the stress level in critical hotspots, improving the overall fatigue life of the bridge over an established lifetime. © 2019 Alessio Pipinato.",,,,,,,,,,,,,,,,,,"Committee on fatigue and fracture reliability of the committee on structural safety and reliability of the structural division.

This dynamometer can replace different cutter heads using flange connections. In order to improve the strain effect of the dynamometer, the strain film sensor is fixed on the regular octagonal connection plates on both ends of the elastomer by vacuum brazing, and the stepped groove structure is also designed inside the elastomer. The dynamometer model is simplified as a four-segment cantilever beam which has different sections. The measurement mechanism model of the dynamometer system is established by the transformation relationship between deflection and strain, under external force. The standard turning tool of 20 mm square is used as a reference. The influence of the structural dimensions of the dynamometer on its strain sensitivity coefficient K is studied. The applicability of the theoretical model of dynamometer strain is verified by finite element analysis. Finally, the dynamometer with the largest K value is subjected to the bending test and compared with a standard turning tool. The experimental results show that the measurement sensitivity of the dynamometer is 2.32 times greater than that of the standard turning tool. The results also show that this dynamometer can effectively avoid the influence of the pasting process on strain transmission, thus indicating its great potential for measuring cutting force in the future. © 2019 by the authors.","Dynamometer; Film sensor; Strain sensitivity coefficient; Structural dimensions","Cutting; Elastomers; Thin film circuits; Thin films; Turning; Vacuum brazing; Design and analysis; Measurement mechanism; Measurement sensitivity; Strain sensitivity coefficient; Strain transmission; Structural dimensions; Theoretical modeling; Thin film resistors; Dynamometers",,,,,"National Natural Science Foundation of China, NSFC: 51875533","This work is supported by the National Natural Science Foundation of China (51875533), the International Exchange and Cooperation Project, Shanxi, China (2015081018), Shanxi Provincial Natural Science Foundation (201701D121079)",,,,,,,,,,"Uquillas, D.A.R., Yeh, S.S., Tool holder sensor design for measuring the cutting force in CNC turning machines (2015) Proceedings of the 2015 IEEE International Conference on Advanced Intelligent Mechatronics (AIM), pp. 1218-1223. , Busan, Korea, 7-11 July; Öztürk, E., Kemal, Y., A new static calibration methodology for strain gage integrated dynamometers (2016) Int.

The flanges of the GFRP deck panel were reinforced with uniformly spaced steel wires to increase the flexural stiffness of the panel. A total of nine full size GFRP deck panel specimens were tested under static and fatigue loadings. The load-deflection behavior and ultimate strength of the deck specimens were compared with those of the unreinforced specimens. The test results were also compared with the results of finite element analysis. The steel reinforcement of the steel reinforced GFRP panels was only 2.5% of the cross-sectional area of the GFRP composite. The test results indicated that, at the design load level, the flexural stiffness of the steel reinforced GFRP panels was approximately 12.3% greater than that of the unreinforced GFRP panels. The test results further revealed that the fatigue loading up to 120% of the design load did not influence the stiffness of the steel reinforced GFRP deck panel. © 2018 Elsevier Ltd","Bridge deck; Fatigue; FRP deck; Glass fibers; Mechanical testing","Beams and girders; Bridge decks; Fiber reinforced plastics; Glass fibers; Mechanical testing; Reinforcement; Steel testing; Stiffness; Wire; Cross sectional area; Fatigue loadings; Flexural stiffness; FRP deck; Glass fiber reinforced polymer; Load deflection behavior; Steel reinforcements; Ultimate strength; Fatigue of materials",,,,,,"The authors would like to acknowledge financial support from Yooho Construction Co.

First, the structural performance of the deck under static loading is evaluated experimentally. Then the results are validated by a finite element program. Results of the numerical analysis are in good agreement with those of the experiments. The load–displacement relationship, ultimate flexural resistance, failure mode, neutral axis, and strain distribution on glass fiber-reinforced polymer layer and concrete slab are examined during the test. Final results revealed that the ultimate failure of the composite deck initiates by longitudinal cracking on the top surface of the concrete slab. No debonding occurs at the interface between concrete slab and steel boxes which indicates that perfobond ribs could be effectively used for shear connection. The results of experimental and numerical analysis demonstrated that the bridge deck possesses desirable strength and meets the stiffness requirements. © The Author(s) 2017.","Composite structures; experiment; finite element analysis; glass fiber-reinforced polymer; mechanical behavior","Bridge decks; Composite bridges; Composite structures; Concrete slabs; Cost effectiveness; Experiments; Fiber reinforced plastics; Finite element method; Glass fibers; Polymers; Reinforced plastics; Reinforcement; Steel fibers; Experimental and numerical analysis; Finite element programs; Flexural resistance; Glass fiber reinforced polymer; Longitudinal cracking; Mechanical behavior; Strain distributions; Structural performance; Reinforced concrete",,,,,"18672","The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This research is supported by Mazandaran Road and Urban Department of Iran and the Housing and Urban Development Research Center (grant no. 18672).

All presented considerations are based on a MATLAB-SIMULINK platform. The nonlinear mathematical model of the analyzed SRM drive was obtained as a combination of the two dimensional (2D) finite element model (FEM) of the motor and the nonlinear model of the electrical network of the power supply circuit. The main model and its seven sub-modules, such as the controller module, one phase simulation module, rotor position angle transformation module, power system module, phase current operation module, “subsystem” module, and electromagnetic torque of one phase operation module, are described. MATLAB functions store the magnetization curves data of the motor obtained by the 2D FEM electromagnetic field calculations, as well as the data of magnetic co-energy curves of the motor calculated from the magnetization curves. The 2D specimen insert method is adopted in MATLAB functions for operating the flux linkage and the magnetic co-energy at the given phase current and rotor position. The phase current waveforms obtained during simulations match with the tested experimentally phases current waveforms at the same rotor speed and the same load basically. The simulated rotor speed curves also agree with the experimental rotor speed curves. This means that the method of suggested nonlinear simulation models of the analyzed SRM drive is correct, and the model is accurate. © 2020 by the authors.

An existing model is considered to validate the present results. A convergence study is carried out to decide the optimum mesh size. An exhaustive parametric study is carried out in which the effect of skewness and curvature on the maximum bending moment, shear force, torsional moment and vertical deflection in both the girders of a single-cell RC skew-curved box-girder bridge is investigated and the results are presented in comparison to a straight bridge. The curve angle varies from 0° to 60° at an interval of 12° and the skew angle varies from 0° to 60° at an interval of 10°. The highly skew-curved bridge is found to be more beneficial than the curved bridge because the bending moment and deflection are less in the skew-curved bridge than that in the curved bridge. The present study may be useful to the engineers in designing the skew-curved RC box-girder bridges. © 2020 Institution of Structural Engineers","Curve angle; FEM; IRC class-70R track load; Single-cell; Skew angle; Skew-curved box-girder bridge",,,,,,"Motilal Nehru National Institute of Technology Allahabad, MNNIT","The authors acknowledge Motilal Nehru National Institute of Technology Allahabad for providing financial support under TEQIP- III.",,,,,,,,,,"Sisodiya, R.G., Cheung, Y.K., Ghali, A., Finite element analysis of skew, curved box-girder bridge (1970) Publ Kajima Inst Constr Technol Jpn, 30, pp. 191-199; Jawanjal, V.S., Kumar, M., Finite element analysis of skew-curved RC box girder bridges (2006) Adv Bridge Eng, pp. 183-190; Khaloo, A., Mirzabozorg, H., Load distribution factors in simply supported skew bridges (2003) J Bridge Eng, 8 (4), pp. 241-244; Menassa, C., Mabsout, M., Tarhini, K., Frederick, G., Influence of skew angle on reinforced concrete slab bridges (2007) J Bridge Eng, 12 (2), pp. 205-214; Khaloo, A., Kafimosavi, M., Enhancement of flexural design of horizontally curved prestressed bridges (2007) J Bridge Eng, 12 (5), pp. 585-590; Kim, W., Laman, J., Linzell, D., Live load radial moment distribution for horizontally curved bridges (2007) J Bridge Eng, 12 (6), pp. 727-736; Fangping, L., Jianting, Z., The deformation analysis of the curved box girder bridges under different radius (2012) Mod Appl Sci, 6 (4), pp. 71-76; Mohseni, I., Rashid, A., Transverse load distribution of skew cast-in-place concrete multicell box-girder bridges subjected to traffic condition (2013) Lat Am J Solids Struct, 10, pp. 247-262; Wilson, T., Mahmoud, H., Chen, S., Seismic performance of skewed and curved reinforced concrete bridges in mountainous states (2014) Eng Struct, 1 (70), pp. 158-167; Miner, L.R., Effect of abutment skew and horizontally curved alignment on Bridge reaction forces (2014), Master's thesis California State University Sacramento, Spring; Deng, Y., Phares, B.M., Greimann, L., Behavior of curved and skewed bridges with integral abutments (2015) J Construct Steel Res, 30 (109), pp. 115-136; Gupta, T., Kumar, M., Flexural response of skew-curved concrete box-girder bridges (2018) Eng Struct, 163, pp. 358-372; Gupta, T., Kumar, M., Reaction response of horizontally curved and skewed concrete box-girder bridges (2019) Recent Adv Struct Eng, 1, pp. 49-60; Gupta, N., Agarwal, P., Pal, P., Free vibration analysis of RCC curved box girder bridges (2019) Int J Tech Innov Modern Eng Sci, 5, pp. 1-7; Agarwal, P., Pal, P., Mehta, P.K., Analysis of RC skew box girder bridges (2019) Int J Sci Innov Eng Tech, 6, pp. 1-8; Agarwal, P., Pal, P., Mehta, P.K., Finite Element Analysis of Skew Box-Girder Bridges.

Finite element models have been proposed as suitable tools for analyzing the complex link between the local tissue structure and the fracture resistance of cortical bone. However, previous models that could capture realistic crack paths in cortical bone were due to the required computational effort limited to idealized osteon geometries and small (&lt;1 mm2) model domains. The objective of this study was therefore to bridge the gap between experimental and numerical analysis of crack propagation in cortical bone by introducing image-based models at the mesoscale. Tissue orientation maps from high-resolution micro-CT images were used to define the distribution and orientation of weak interfaces in the models. Crack propagation was simulated using the extended finite element method in combination with an interface damage model, previously developed to simulate crack propagation in microstructural osteon models. The results showed that image-based mesoscale models can be used to capture interactions between cracks and microstructure. The simulated crack paths predicted the general trends seen in experiments with more irregular patterns for cracks propagating perpendicular compared to parallel to the osteon orientation. In all, the proposed method enabled an efficient description of the tissue level microstructure, which is a necessity to predict realistic crack paths in cortical bone and is an important step towards simulating crack propagation in bone models in 3D. © 2020 Elsevier Ltd","Micro-CT; Microstructural orientation; Toughness; XFEM","Bone; Computerized tomography; Crack propagation; Finite element method; Microstructure; Tissue; Computational effort; Experimental and numerical analysis; Extended finite element method; Image-based models; Interface damages; Meso-scale models; Micro-structural; Toughening mechanisms; Cracks; article; controlled study; cortical bone; extended finite element method; Haversian canal; micro-computed tomography; simulation; tissue level; biological model; bone; cortical bone; diagnostic imaging; fracture; human; mechanical stress; Bone and Bones; Cortical Bone; Fractures, Bone; Haversian System; Humans; Models, Biological; Stress, Mechanical",,,,,"Stiftelsen för Strategisk Forskning, SSF: IB2013–0021; Lunds Universitet","This work was supported by the Swedish Foundation for Strategic Research [Grant Number IB2013–0021 ].

Fatigue damage readily occurs because it is directly subjected to repeated load. In this paper, fatigue and static loading tests were conducted on modular bridge expansion joint (MBEJ). This is an innovative type of shallow-buried modular bridge expansion joint, and the anchoring depth is reduced by 40%-50% compared with traditional ones. The reduced overall height can well adapt to the slide shutter rapid construction method in practical engineering. A loading device was designed to simulate vertical and horizontal load. The load-deflection relationship after fatigue loading were discussed. The fatigue crack types, crack initiation locations, failure criteria, and fatigue failure modes of MBEJs were also studied. Following that, a finite element model was established to calculate the internal force of welded connections. Structural analysis on MBEJs was used to calculate the stress range within center beam and support bars under the test conditions. A theoretical fatigue performance assessment method on MBEJs was introduced, which is based on the nominal stress method and a linear Miner damage accumulation rule. The theoretical prediction agreed well with the experimental observations. © 2020 Elsevier Ltd","Bridge engineering; Failure modes; Fatigue crack; Modular bridge expansion joint; Nominal stress","Composite bridges; Damage detection; Expansion joints; Fatigue damage; Loads (forces); Bridge expansion joints; Damage accumulation rule; Fatigue failure mode; Fatigue performance; Load-deflection relationships; Nominal stress methods; Practical engineering; Static loading test; Cracks; bridge construction; buried structure; failure mechanism; fatigue; finite element method; innovation; loading test; stress; structural component",,,,,"201620; 2019RS2035, 2019SK2171; National Natural Science Foundation of China, NSFC: 51778068; Natural Science Foundation of Hunan Province: 2019JJ30024; Hunan Provincial Innovation Foundation for Postgraduate: CX20190672; Training Program for Excellent Young Innovators of Changsha: kq1802012","This work is conducted with the financial support from Hunan Transportation Technology Project of China ( 201620 ), the National Natural Science Foundation of China ( 51778068 ), the Special Funds for the Construction of Innovative Provinces in Hunan Province of China ( 2019RS2035 , 2019SK2171 ), the Natural Science Foundation of Hunan Province ( 2019JJ30024 ), the Training Program for Excellent Young Innovators of Changsha ( kq1802012 ), and Hunan Provincial Innovation Foundation for Postgraduate ( CX20190672 ).

First, the machine topology and drive system configuration of the proposed design is illustrated. The design specifications and requirements are introduced. Some key design parameters on torque performance are investigated, including the effect of iron bridges, effect of rotor pole shaping, and rotor skewing. The demagnetization risk of the proposed design is also evaluated. Finally, the open-circuit electromagnetic characteristics and on-load torque capability are predicted by finite element analysis. The performance of the proposed design is compared to the rare-earth interior permanent magnet motor and synchronous reluctance motor. The toque density is competitive to that of rare-earth permanent magnet motor with fractional slot concentrated windings. More importantly, the proposed dual three phase spoke-type ferrite traction motor offers several advantages, including low-cost, non-rare-earth magnets, and fault tolerant. © 2020 IEEE.","Dual three phase; electric vehicles; ferrite; permanent magnet; rare-earth free; spoke-type; traction","AC motors; Energy conversion; Ferrite; Permanent magnets; Rare earths; Reluctance motors; Design specification; Ferrite permanent magnets; Fractional slot concentrated windings; Key design parameters; Permanent magnet synchronous; Rare earth permanent magnet; Rotor-pole-shaping; Synchronous Reluctance motor; Traction motors",,,,,,,,,,,,,,,,"Levi, E., Multiphase electrical machines for variable-speed applications (2008) IEEE Trans.

Owing to the tedious maintenance and replacement process, it is difficult to reduce maintenance costs and traffic impacts for conventional anchorage systems. To solve this problem, this paper presents the development of a novel prestressed anchorage system used in the Nansha Bridge. The novel anchorage system employs finite bundles of cluster cables with multiple anticorrosive coatings, enabling monitorability and durability and efficient replaceability without traffic interruption. A replaceability model test is performed to reveal the mutual interference characteristics of cluster cable tension and verify the replacement efficiency. Graded load tests are carried out on three specimens to investigate the stress distribution and load-carrying performance. Through elaborate 3D finite element analysis, the mechanical behaviour and stress diffusion characteristics of the crucial components under the anchors are further studied under three extreme scenarios. The results show that the novel anchorage system is reliable with a sufficient safety margin and uniform stress distribution and that the replacement process is efficient without incurring traffic interruption. © 2020 Institution of Structural Engineers","Cable anchorage system; Cluster cable; Model test; Replaceability; Suspension bridge",,,,,,"National Natural Science Foundation of China, NSFC: 51878059; China Postdoctoral Science Foundation: 2019M653519; Natural Science Foundation of Shaanxi Province: 2020JM-219; National Key Research and Development Program of China, NKRDPC: 2018YFB1600300","This work is supported by the Natural Science Foundation of Shaanxi Province , China [Grant No. 2020JM-219 ], the China Postdoctoral Science Foundation [Grant No. 2019M653519 ], the National Key Research and Development Project of China [Grant No. 2018YFB1600300 ], and the National Natural Science Foundation of China [Grant No. 51878059 ].",,,,,,,,,,"Frangopol, D.M., Soliman, M., Life-cycle of structural systems: recent achievements and future directions (2014) Struct.

To achieve this purpose, the geometric model of the bridge with a 90 m length including 42 numbers of steel piles was designed using CATIA software. Next, two different stress analyses including static analysis (in order to study the effect of motionless water) and transient dynamic analysis (in order to study the effect of sea waves clash) were performed for extracting the total deformation on the top part of the piles. The finite element results indicated that motionless water has no significant effect on the mechanical behavior of the bridge piles. But the sea waves clash with the piles caused a deformation on the piles. Eventually, the fatigue life of the H cross-section steel pile subjected to the sea waves clash was predicted using two different techniques (finite element simulation and probabilistic approach). The results reveal that the motionless water has no ability to cause fatigue damage to the different parts of an integral concrete bridge. Moreover, it is found that the useful lifetime of steel piles under variable amplitude loading caused by sea waves clash is 39 and 34 years based on the FE and probabilistic analyses, respectively. © 2020, ASM International.","Axial fatigue; Finite element analysis; H-steel piles; Integral concrete bridge; Sea waves; Variable amplitude loading","Concrete bridges; Concretes; Deformation; Piles; Static analysis; Transient analysis; Water waves; Fatigue life assessment; Finite element simulations; Geometric modeling; Mechanical behavior; Probabilistic analysis; Probabilistic approaches; Transient dynamic analysis; Variable amplitude loading; Fatigue of materials",,,,,,,,,,,,,,,,"Kashyzadeh, K.R., Arghavan, A., Study of the effect of different industrial coating with microscale thickness on the CK45 steel by experimental and finite element methods (2013) Strength Mater., 45 (6), pp. 748-757; Arghavan, A., Kashyzadeh, K.R., Asfarjani, A.A., Investigating effect of industrial coatings on fatigue damage (2011) Appl.

However, the design of this type of machine is a difficult task and there is no methodology to provide an explicit solution. This work aims to contribute for the solution of this problem with the proposal of a new procedure to design tubular linear switched reluctance generators (TLSRG). With the proposed procedure the TLSRG can be designed to develop a given linear force and to achieve better generation efficiency. The design is defined as a minimization problem where an optimization process is used to find the optimal solution for the dimensional parameters. Finite element method (FEM) analysis is applied to compute the relevant electromagnetic characteristics. The mathematical model of the generator conversion system is formulated to evaluate its dynamic performance. An H-Bridge asymmetric converter is adopted to control the energy flow in the generator. The electric currents in the generator phases are adjusted with a hysteresis controller. A TLSRG with a maximum mean force of 120 kN is designed by applying the proposed procedure, implemented in Matlab® and combined with MagNet® (FEM commercial software) to compute the electromagnetic characteristics of the machine. The system mathematical model is solved in Simulink®. The dynamic simulations are performed for a constant velocity of 1.3 m/s. For these operating conditions, the generator is characterised with an output power of 126.2 kW and an efficiency of 82.1%. The control proposed to drive the TLSRG is experimentally tested on a small-scale prototype. The experimental results show the effectiveness of the controller in keeping the phase current near the reference value. © 2020 Elsevier Ltd","Direct drive conversion; Ocean wave energy; Switched reluctance machine; Tubular linear generator","Bridge circuits; Controllers; Design; Hydroelectric generators; MATLAB; Oceanography; Synchronous generators; Water waves; Dimensional parameters; Electromagnetic characteristic; Electromagnetic designs; Finite element method analysis; Linear switched reluctance generators; Linear switched reluctance machines; Minimization problems; System mathematical modeling; Wave energy conversion",,,,,"Fundação para a Ciência e a Tecnologia, FCT: SFRH/BD/91626/2012; Instituto de Telecomunicações, IT: 19-29/01/2019 - UID/EEA/50008/2019","R.P.G.

The present study is to assess the buckling strength of a stiffened deck panel on an FPSO vessel using the nonlinear finite element code ADVANCE ABAQUS, where imperfection sensitivity work is also accounted for. The cases studied correspond to in-plane bi-axial compression in the two orthogonal directions. The findings are compared with the DNVGL PULS (Panel Ultimate Limit State) buckling code for the stiffened panels. It is found that the strength values from the ADVANCE ABAQUS and DNVGL PULS code are very close. The results and insights developed from the present work are discussed in detail. © 2020 Sciendo.

However, a holistic framework that efficiently incorporates monitored data into structural identification and, in turn, provides a realistic life-cycle performance assessment of structures is yet to be established. There are different sources of uncertainty, such as structural parameters, computer model bias and measurement errors. Neglecting to account for these factors results in unreliable structural identifications, consequent financial losses, and a threat to the safety of structures and human lives. This paper proposes a new framework for structural performance assessment that integrates a comprehensive probabilistic finite element model updating approach, which deals with various structural identification uncertainties and structural reliability analysis. In this framework, Gaussian process surrogate models are replaced with a finite element model and its associate discrepancy function to provide a computationally efficient and all-round uncertainty quantification. Herein, the structural parameters that are most sensitive to measured structural dynamic characteristics are investigated and used to update the numerical model. Sequentially, the updated model is applied to compute the structural capacity with respect to loading demand to evaluate its as-is performance. The proposed framework's feasibility is investigated and validated on a large lab-scale box girder bridge in two different health states, undamaged and damaged, with the latter state representing changes in structural parameters resulted from overloading actions. The results from the box girder bridge indicate a reduced structural performance evidenced by a significant drop in the structural reliability index and an increased probability of failure in the damaged state. The results also demonstrate that the proposed methodology contributes to more reliable judgment about structural safety, which in turn enables more informed maintenance decisions to be made. © 2020 World Scientific Publishing Company.","box girder bridge & modular Bayesian approach; Finite element model updating; Gaussian process; reliability analysis; structural dynamic","Box girder bridges; Finite element method; Gaussian distribution; Gaussian noise (electronic); Life cycle; Losses; Reliability analysis; Steel bridges; Structural analysis; Structural dynamics; Uncertainty analysis; Computationally efficient; Dynamic characteristics; Finite-element model updating; Probabilistic finite elements; Structural identification; Structural reliability analysis; Structural reliability indices; Uncertainty quantifications; Structural health monitoring",,,,,"Australian Research Council, ARC","The research herein is part of Discovery Project DP160101764 funded by the Australian Government through the Australian Research Council (ARC).

Moreover, the large negative bending moment and shear force in the box girder near the piers may lead to cracks in the top slabs and webs. To improve the structural performance and mitigate the long-term deflection of bridges, a novel type of open-web continuous reinforced-concrete rigid-frame bridge was developed during the design of the Beipan River Bridge with a 290-m main span. In this paper, the design and construction techniques of the novel bridge type are summarized first. Then, a structural analysis of the Beipan River Bridge is conducted. The results are compared with conventional rigid-frame bridges. Moreover, the long-term girder deflections are checked through the combined application of monitoring data and finite-element analysis. The results show that the bridge alignment is quite stable during the first 5 years in service and that the open-web design philosophy can effectively mitigate the long-term girder deflections. © 2020 American Society of Civil Engineers.","Continuous reinforced-concrete rigid-frame bridge; High pier; Long-span bridge; Long-term deflections; Open-web; Relaxation of prestressing tendons; Shrinkage and creep of concrete","Box girder bridges; Composite beams and girders; Concrete construction; Deflection (structures); Rigidity; Shrinkage; Wire; Design and construction; Design philosophy; Long-term deflections; Negative bending; Prestressing tendon; Rigid-frame bridges; Shrinkage and creep; Structural performance; Reinforced concrete",,,,,"KJFZ-2019-029","The authors would like to thank all the engineers, technicians, and researchers involved in the design and construction of the Beipan River Bridge.

In addition, flood-induced scour has been recognized as a leading cause of bridge failure. However, current bridge performance assessment often takes the original bridge configuration as the basis for analyzing such impact without considering the effects of scour depth. In this paper, high-resolution finite-element (FE) based modeling is conducted to investigate barge impact on the nonlinear response of a pile-supported bridge with variable scour depths. The significant findings are multifold. First, it is favorable to find that the peak impact force and the crush deformation in the bow of the barge generally do not change significantly as scour depth varies. However, it is cautious to note that the peak displacement at the pier and the local deformation in the piles significantly increases as scour depth increases. It is stated that these findings and the method in this paper can assist in the quantitative assessment of the performance of river-crossing bridges in service and may provide information for the development of the next-generation bridge design specifications regarding barge impact. © 2020 American Society of Civil Engineers.","Barge impact; Bridge; Finite-element method; Impact force; Scour depth","Barges; Bridge piers; Deformation; Failure (mechanical); Piles; Bridge configuration; Bridge performance; Local deformations; Non-linear response; Peak displacement; Peak impact forces; Quantitative assessments; Supported bridges; Scour",,,,,"University of Missouri, MU; National Natural Science Foundation of China, NSFC: 51708484; Natural Science Foundation of Jiangsu Province: BK20170511; Natural Science Research of Jiangsu Higher Education Institutions of China: 17KJB580010","The first author thanks the support from the National Natural Science Foundation of China through Grant No. 51708484, Natural Science Foundation of Jiangsu Province through Grant No. BK20170511, and Natural Science Foundation of the Higher Education Institutions of Jiangsu Province through Grant No. 17KJB580010.

Direct quantification of the material imperfections represents an extremely difficult task for this type of structure. On the other hand, the geometrical imperfections can be measured in more detail by using special scanners or high-accuracy surveying instruments. This contribution represents a beginning part of the research activities focusing on the real values of geometric imperfections of existing steel arch bridges using three-dimensional (3D) scanning. The possibility of using these data for further theoretical and numerical analysis based on the finite element method (FEM) and for further creating the building information modelling (BIM) of the bridges is proposed. When verifying the stability of bow-string arch bridges, much higher attention has to be paid to the out-of-plane stability of the arches. The numerical models of an existing bridge superstructure were developed to execute a nonlinear analysis with geometrical imperfections included. Both the theoretical and actual imperfections obtained by 3D scanning were taken into account. The obtained data, their comparison and the applicability of the presented method are finally discussed. © 2020 by the authors.

The ability of RC slabs to distribute concentrated loads due to the pressure of wheels in a transverse direction is an important property for their verification. The main goal of this paper is to investigate the effect of the redistribution of shear forces on the load-carrying capacity of RC slabs subjected to a concentrated load. Several methods and design models for the assessment of one-way shear capacity were tested and statistically evaluated according to the results of 43 experiments carried out in the last two decades. The analyses showed that the effective shear width method provides unsafe results for higher values of the clear shear span to effective depth ratio unless the same limits are not imposed. Limiting the distance of the critical section from the inner edge of the loaded area significantly improved the accuracy of the method. The best results were obtained for the ACI 318-14 and AASHTO LRFD models in combination with a French approach when the CoV reached values of 0.091 and 0.097, respectively.

However, there is a scarcity of shaking table tests validating the traveling wave resonance. A 1/70-scale pile-soil-cable-stayed bridge model was fabricated following the preliminary design of a cable-stayed bridge with a main span of 1400 m. Shaking table tests were performed to verify the traveling wave and mode shape resonances in the seismic response of the bridge model when separately subjected to two specific sine waves longitudinally. The vertical acceleration frequency spectra and seismic response of the bridge model were compared between uniform and non-uniform sine wave excitation. The results showed that the traveling wave and mode shape resonances were examined in the seismic response of the pile-soil-cable-stayed bridge model under non-uniform excitation of the specific sine waves. The traveling wave excitation increased the symmetric response at the symmetric girder location but decreased the antisymmetric responses of the towers and girder, compared to the uniform excitation regarded as antisymmetric input. Finally, a finite element model was developed in OpenSees that could capture the seismic response changes caused by the traveling wave effects of the specific sine waves and proximately reproduce the experimental results. Therefore, the traveling wave and mode shape resonances were verified by the numerical simulations. © 2020 Elsevier Ltd","Mode shape resonance; Non-uniform excitation; Pile-soil-cable-stayed bridge model; Shaking table testing; Traveling wave resonance","Cables; Electron resonance; Piles; Seismic design; Seismic response; Soil testing; Soils; Mode shapes; Non-uniform excitations; Shaking table testing; Shaking table tests; Traveling wave; Traveling wave effect; Traveling wave excitation; Vertical accelerations; Cable stayed bridges; bridge; finite element method; numerical model; pile; resonance; seismic design; seismic response; shaking table test; soil-structure interaction",,,,,"National Natural Science Foundation of China, NSFC: 51608282, 91515101-5; Tongji University; State Key Laboratory for Disaster Reduction in Civil Engineering","This study was supported by the National Natural Science Foundation of China [51608282, 91515101-5].

Strain gauges were attached with the mechanical rings to detect the deformation, during the machining process. Wheatstone bridge circuit was equipped with gauges to acquire the strain as voltage owing to the deformation of mechanical rings when machining takes place. The finite element analysis (FEA) was used to identify the location of maximum deformation and stress. The direction of rings and location of gauges were decided to increase the sensitivity and decrease the cross-sensitivity. Then, the cutting force was acquired through NI 6221 M series data acquisition (DAQ) card. The dynamometer had undergone a cycle of tests to verify its static and dynamic characteristics. The metrological characterization was performed according to the calibration procedure based on ISO 376 - 2011 standard. The cutting force was measured with both the dynamometers through milling experiments based on Taguchi's L9 orthogonal array and the results were recorded. The measured cutting force varied from 300 N to 550 N. The obtained results depicted that low-cost milling dynamometer was reliable to measure the three component machining force. Overall, the square ring based dynamometer provides the better static and dynamic characteristics in terms of linearity, cross-sensitivity (4%), uncertainty (0.054%), and natural frequency (362.41 rev/s). © The Authors 2020.","Cutting force; Milling dynamometer; Milling process; Octagonal ring; Square ring; Strain gauge; Uncertainty analysis",,,,,,"All India Council for Technical Education, अभातशिप: F No.11-33/RIFD/CAYT/POL-I/2014-15","This research is supported by the AICTE – Career award for Young Teachers research grant (F No.11-33/RIFD/CAYT/POL-I/2014-15).

However, no available methods are provided in current specifications for the thermal effect calculation. To fill this gap, large-scale temperature measurements and fine finite-element model (FEM) analysis were performed on an actual composite girder bridge. Based on the fully validated FEM, a comprehensive parametric study was carried out to establish the spatio-temporal pattern of hydration-caused temperature, including a vertical pattern and an evolutionary pattern. Finally, a simplified method was presented for the thermal stress calculation of composite girders, and a case study was also provided. Measurements showed that temperature differences of concrete deck varied below 5 °C, much smaller than the entire composite section. FEM analysis then suggested that the influence of solar radiation can be basically ignored compared with hydration heat. The spatio-temporal pattern in the form of the coefficient of temperature rise was proposed based on the above findings and parametric study, and the reliability was properly verified with experimental or FEM results. For the final simplified method, the case study demonstrated that it can effectively facilitate the thermal stress calculation of composite girders during hydration process by adopting the proposed spatio-temporal pattern. As such, preliminary curing schemes can be easily selected to control the concrete cracking risk before casting. © 2020, Wroclaw University of Science and Technology.","Coefficient of temperature rise; Cracking risk; Hydration heat; Spatio-temporal pattern; Steel–concrete composite girder; Temperature distribution","Composite beams and girders; Finite element method; Hydration; Temperature measurement; Thermal stress; Composite girder bridges; Composite sections; Concrete composites; Early age concrete; Spatiotemporal patterns; Temperature changes; Temperature differences; Thermal stress calculation; Concrete beams and girders",,,,,"National Natural Science Foundation of China, NSFC: 300102219310, 51978061","This work was supported by the National Natural Science Foundation of China, Grant No.: 51978061, and the Special Fund for Basic Scientific Research of Central College of Chang’an University, Grant No.: 300102219310.",,,,,,,,,,"Noorzaei, J., Bayagoob, K.H., Thermal and stress analysis of Kinta RCC dam (2006) Eng Struct, 28, pp. 1795-1802; Honorio, T., Bary, B., Benboudjema, F., Evaluation of the contribution of boundary and initial conditions in the chemo-thermal analysis of a massive concrete structure (2014) Eng Struct, 80, pp. 173-188; Xia, Y., Nassif, H., Su, D., Early-age cracking in high performance concrete decks of a curved steel girder bridge (2016) J Aerospace Eng, 30, p.

The two most common structures are hex and non-hex abutments. The non-hex abutment typically furnishes a larger contact area between itself and the implant than that provided by a hex structure. However, when a hex abutment is loaded, the position of its contact area may be deeper than that of a non-hex abutment. Hence, the purpose of this study is to determine the different biomechanical behaviors of an internal bone-level implant based on the abutment type—hex or non-hex—and clinical crown length under static and cyclic loadings using finite element analysis (FEA). The hex structure was found to increase the implant and abutment stability more than the non-hex structure among several criteria. The use of the hex structure resulted in a smaller volume of bone tissues being at risk of hypertrophy and fatigue failure. It also reduced micromovement (separation) between the implant components, which is significantly related to the pumping effect and possible inflammation. Both static and fatigue analyses, used to examine short- and long-term stability, demonstrated the advantages of the hex abutment over the non-hex type for the stability of the implant components. Moreover, although its impact was not as significant as that of the abutment type, a large crown-implant ratio (CIR) increased bone strain and stress in the implant components, particularly under oblique loading.

These structures are generally old and have historical value. Considering the increased axial load and passing speed from these bridges, an in-depth study of these structures and their potential is of paramount importance. In the present study, an old masonry arch bridge located in 475 km of Western Iranian railway is investigated. For the detailed modeling of this structure, a three-dimensional finite element method (3DFEM) was implemented to take into account the details of the bridge and the train passing over it. The developed model was calibrated and validated using the dynamic field test results. The obtained results showed that the increase in the axial load and train speed over the bridge must be done carefully because exceeding the travel speed of 90 km/h and increasing the axial load from 20 to 30 ton makes serious problems in the bridge and interrupts its performance. Furthermore, it was found that the adequacy factor of the bridge under the standard load of LM71 is over 2. © 2020, Budapest University of Technology and Economics.

This bridge is mainly used to connect the berth in Lamong gulf and the port in Java Island for the logistic purposes. The bridge was retrofitted 26 years into its life by adding two strips of carbon fiber reinforced polymer (CFRP) due to excessive cracks observed in the beams. Non-destructive field measurements were compared against a detailed finite element analysis of the structure to predict the performance of the girder in terms of deflection and moment capacity before and after the retrofitting work. The analysis was also used to predict the long-term deflections of the structure due to creep, crack distribution, and the ultimate moment capacity of the individual girder. Moreover, the finite element analysis was used to predict the deflection behavior of the overall bridge due to vehicle loading. Good agreement was obtained between the field measurement and the analytical study. Anew service life of the structure considering the corrosion and new vehicle demand is carried out based on field measurement using non-destructive testing. Not only are the specific results beneficial for the Indonesian port authority as the stakeholder to manage this structure, but the approach detailed also paves the way for more efficient evaluation of bridges more generally over their service life. © 2020 by the authors.","Bridge; Crack; Durability; FEM; Seaport",,,,,,,"This research was funded by Australian Indonesian Centre (AIC): Project Title: Structural Performance of Critical Infrastructures in Port Development, Infrastructure Cluster Strategic Projects, Strategic Research Project 2 (SRP2), 2016.

While the current studies on FHSB T-stub connections mainly focus on the structural behaviors under both shear and tensile force, no research has been reported on the mechanical responses of the connections under the combined effects of shear and compression. To make up for this gap, this paper presents a novel FHSB T-stub connection, which is simple in structure, definite in load condition, and easy to construct. Static load tests were carried out on 21 specimens under different shear-compression ratios, and the finite-element (FE) models were created for each specimen. The failure modes, initial friction loads and ultimate strengths of the specimens were compared in details. Then, 144 FE models were adopted to analyze the effects of the friction coefficient, shear-compression ratio, bolt diameter and clamping force on the initial friction load and ultimate strength. The results showed that the FHSB T-stub connection under shear and compression mainly suffers from bolt shearing failure. The load-displacement curve generally covers the elastic, yield, hardening and failure stage. If the shear-compression ratio is small and the friction coefficient is large, its curve only contains the elastic and failure stage. The friction coefficient and shear-compression ratio have great impacts on the initial friction load and ultimate strength. For every 1 mm increase in bolt diameter, the initial friction load increased by about 10%, while the ultimate strength increased by about 8.5%. For each 10% increase/decrease of the design clamping force, the initial friction load decreases/increases by 7.8%, while the ultimate load remains basically the same. The proposed formula of shear capacity and self-lock angles of FHSB T-stub connection can be applied to the design of CSS-enhanced prestressed concrete continuous box girder bridges (PSC-CBGBs) and diagonal bracing. © 2020 by the authors.

This inherent radial force can be properly utilized, if produced using an external power source and controlled actively using a controlled algorithm for bearingless operation of the motor. This paper presents a single set of stator winding called bridge configured winding, which has the ability to generate both torque and radial force. The winding structure forms two sets of terminal connections in each phase's winding, one for the torque production and one for generating controllable radial force for suspension of the motor. The potential paths and commutation period for the winding currents to produce both torque and radial forces are identified, and an analytical model is developed for a 12/8 bearingless switched reluctance motor. The principle and insight of the proposed single winding scheme and its behaviour with the incorporation of the power converter circuits coupled with a speed-current controlled drive system are analysed using a finite element model for both motoring and radial force production. The finite element–based results are validated with the analytical results obtained. © 2020 John Wiley & Sons Ltd","bearingless switched reluctance motor (BSRM); bridge configured winding (BCW); finite element model; radial force; switched reluctance motor (SRM)","Electric machine theory; Electric motors; Finite element method; Magnetic devices; Reluctance motors; Speed regulators; Torque; Winding; Analytical results; Bearingless switched reluctance motor; Bearingless switched reluctance motor (BSRM); Bridge configured winding; Converter circuits; Radial forces; Switched Reluctance Motor; Terminal connections; Electric machine control",,,,,,,,,,,,,,,,"Takemoto, M., Shimada, K., Chiba, A., Fukao, T., A design and characteristics of switched reluctance type bearingless motors (1998) Proc.

The cooling rates are related to the free opening of the furnace at 800 °C (extreme case) and the restricted opening when the restoration reaches 450 °C (slow case). The thermal expansion coefficients of the materials and the glass transition point of the ceramic were measured experimentally using a dilatometer test. The FEA was performed based on the ceramic temperature profile, which was determined experimentally by using thermocouples type K. When the dental ceramic reaches its transition temperature (Tg) at 510 °C, maximum principal stress at the grooves from the occlusal surface of the pontic are reported as 140 MPa for the slow and 400 MPa for the fast cooling rate. Additionally, it is demonstrated that stresses can be reduced by using low Young's modulus metals and with small differences in the material's thermal expansion coefficient (CTE). © 2020 Elsevier Ltd","Cooling phase; Flexural strength; Glaze treatment; Metal-ceramic","Bending strength; Cermets; Cooling; Dental materials; Elastic moduli; Expansion; Glass transition; Glazes; Metals; Stress analysis; Thermal expansion; Thermocouples; Accumulated stress; Comsol multiphysics; Cooling phase; Glass transition points; Low young's modulus; Maximum principal stress; Temperature profiles; Thermal expansion coefficients; Finite element method; metal; dental porcelain; Article; cooling; dental restoration; finite element analysis; furnace; priority journal; surface property; temperature sensitivity; temperature stress; thermal conductivity; transition temperature; Young modulus; ceramics; cold; dental procedure; finite element analysis; materials testing; mechanical stress; Ceramics; Cold Temperature; Dental Porcelain; Dental Stress Analysis; Finite Element Analysis; Materials Testing; Stress, Mechanical",,"Dental Porcelain",,,,"We would like to offer special thanks to Glidwell Dental labs for the support during the research work.

The current study examined stress concentration factors for non-90° (Y-type) joints. A total of 11 Y-joints were tested under axial tension, and the hot spot stresses were measured.

For traditional rear anchor girder anchorage system and pre-stressed anchorage system, problems such as local compression and inconvenient construction are inevitable. This paper presents the development of a novel PBL anchorage system used in the 4th Nanjing Yangtze River Bridge. This PBL anchorage system adopted grouped perfobond rib shear connectors (known as PBL shear connectors) in the independent perforated steel plate. Two full-scale specimens were extracted from the practical design. The load–slip curves and the strain developments were obtained. The results revealed the reliable load-carrying capacity and very slight residual slip after the cyclic unloading from the design load. The load carried by each row of PBL shear connectors proved the distributed load-carrying capacity. Finite-element analyses were conducted in ANSYS, which agreed well with the test results. Further parametric analyses focusing on the spacing and rows of PBL shear connectors were conducted. Based on the analysis results, the design methods of the PBL anchorage system were suggested. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.","full-scale test; load sharing proportion; numerical analysis; PBL anchorage system; Suspension bridges","Anchorages (foundations); Cables; Load limits; Loads (forces); Numerical analysis; Suspension bridges; Unloading; Anchorage systems; Critical structures; Full scale tests; Load sharing; Nanjing Yangtze river bridge; Parametric -analysis; Pbl shear connectors; Perforated steel plates; Suspensions (components)",,,,,"Sichuan Province Science and Technology Support Program: 2019YFH0139; National Natural Science Foundation of China, NSFC: 51708466","This work was completed under the support of the National Natural Science Foundation of China under Grant No. 51708466 and Sichuan Science and Technology Program under Grant No. 2019YFH0139.

The aim of this paper is to design a compact solid state transformer for microgrid application. The proposed transformer has four ports integrated on a single common core. Thus, it can integrate different renewable energy resources and energy storage systems. The transformer is operating at 50kHz switching frequency, and each port can handle 25kW rated power. In this paper, the ports are chosen to represent a realistic industrial microgrid model consisting of grid, energy storage system, photovoltaic system, and load. The grid port is designed to operate at 4160V AC, while the other three ports operate at 400V. Moreover, the grid, energy storage, and photovoltaic ports are active ports with dual active bridge topologies, while the load port is a passive port with full bridge rectifier one. In this paper, an extensive and complete design and modeling of the entire solid state transformer is presented. The proposed design is first validated with simulation results, and then the proposed transformer is implemented. Some preliminary experimental tests are also performed and the obtained results are reported. © 2020 IEEE.","Finite element analysis; high frequency; high power; medium voltage; microgrid multi-port transformer; solid state transformer","Energy storage; Microgrids; Photovoltaic cells; Power electronics; Switching frequency; Design and implementations; Design and modeling; Dual active bridges; Energy storage systems; Four-port transformers; Full bridge rectifier; Photovoltaic systems; Solid state transformer (SST); Renewable energy resources",,,,,"National Science Foundation, NSF: 1650470, 1939124; Türkiye Bilimsel ve Teknolojik Araştirma Kurumu, TÜBITAK","ACKNOWLEDGMENT This material is based upon work supported by the National Science Foundation under Grant No. 1650470.

The construction joints between the concrete cast at different stages reduce the torsional capacity and thus the load-carrying capacity of the slab. However, the present formulations for the torsional capacity, based on limit analysis, only consider monolithically cast slabs. In this paper, the load-carrying capacity of reinforced concrete slab bridges with construction joints are investigated using limit analysis of perfect plastic materials based on the lower bound theorem. New formulations for the torsional capacity of slabs with vertical construction joints and partial construction joints are presented. The load-carrying capacity of slabs is calculated using finite element limit analysis based on the lower bound theorem. For the analysis, a complete yield criteria for the bending moments and torsional moments are setup applying a layer model.

It is found that the wind turbulence parameters during the typhoon and monsoon conditions share a considerable amount of similarity, and they can be described as the input turbulence parameters for the current wind-induced vibration theory. While the longitudinal turbulence integral scales are consistent with those in regional structural codes, the turbulence intensities and gust factors are less than the recommended values. The wind spectra obtained via the field measurements can be well approximated by the von Karman spectra. For the buffeting response of the bridge under strong winds, its vertical acceleration responses at the extreme single-cantilever state are significantly larger than those in the horizontal direction and the increasing tendencies with mean wind velocities are also different from each other. The identified frequencies of the bridge are utilized to validate its finite element model (FEM), and these field-measurement acceleration results are compared with those from the FEM-based numerical buffeting analysis with measured turbulence parameters. © 2020 by the authors.

The aerodynamic lateral force will cause the vehicle sideslip and unsteady steering, which is extremely harmful to driving safety. In this paper, Xi-Han Expressway is taken as the research object to analyze the influencing factors of vehicle's lateral stability by combining the theoretical research of the finite element method, automobile aerodynamics, and speed limit with field investigation and simulation test. CarSim software is used for simulation to explore the influence of different positions of the circular curve on vehicle lateral stability. The results show that the wind level affects the tunnel exit's unfavorable section on the circular curve. The larger the wind level, the larger the proportion of the tunnel exit's unfavorable section on the circular curve. The proportions of tunnel exit's unfavorable section on the circular curve under 6-9 wind levels are 33.33%, 38.89%, 55.56%, and 66.67%, respectively. In addition, the lateral stability of vehicles under level 6-8 wind scale is the worst when the tunnel exit is located at 5° position on the circular curve. The results indicate the influence of strong wind on the lateral stability of vehicles in mountainous expressway. The research can optimize the design of the highway tunnel group and provide the basic theory and method basis for the quantitative management and scientific management of the road traffic management department. © 2020 Lu Wang et al.",,,,,,,,,,,,,,,,,,"Jackson, T.L., Sharif, H.O., Rainfall impacts on traffic safety: Rain-related fatal crashes in Texas (2016) Geomatics, Natural Hazards and Risk, 7 (2), pp. 843-860. , 2-s2.0-84955684874; Ibrahim, A.T., Hall, F.L., Effect of adverse weather conditions on speed-flow-occupancy relationships (1994) Transportation Research Record, 1457, pp. 184-191; Ewan, L., Al-Kaisy, A., Veneziano, D., Remote sensing of weather and road surface conditions (2013) Transportation Research Record: Journal of the Transportation Research Board, 2329 (1), pp. 8-16. , 2-s2.0-84880730968; Baker, C.J., Sterling, M., The calculation of train stability in tornado winds (2018) Journal of Wind Engineering and Industrial Aerodynamics, 176, pp. 158-165. , 2-s2.0-85044517635; Wan-Shui, H., Safety assessment of moving vehicles on a long-span bridge under crosswind and influence factors analysis (2008) Acta Aerodynamica Sinica, 4, pp. 466-472; Han, Y., Huang, J.W., Cai, C.S., Chen, S.R., He, X.H., Driving safety analysis of various types of vehicles on long-span bridges in crosswinds considering aerodynamic interference (2019) Wind and Structures, 29 (4), pp. 279-297; Guang-Jun, G., Hong-Qi, T., Jia, Z., Cross-wind affection on double container train (2004) Journal of Traffic and Transportation Engineering, 4 (2), pp. 45-48; Wang, L., Xu, T., Xue, H., Lu, D.W., A simulation analysis of driving stability in crosswind condition on expressway in mountain areas (2019) Journal of Transport Information and Safety, 37 (3), pp. 20-27; Avadiar, T., Bell, J., Burton, D., Cormaty, H., Li, C., Analysis of high-speed train flow structures under crosswind (2016) Journal of Mechanical Science and Technology, 30 (9), pp. 3985-3991. , 2-s2.0-84988526131; Giappino, S., Rocchi, D., Schito, P., Tomasini, G., Cross wind and rollover risk on lightweight railway vehicles (2016) Journal of Wind Engineering and Industrial Aerodynamics, 153, pp. 106-112. , 2-s2.0-84963612775; Zhang, X., Proppe, C., The influence of strong crosswinds on safety of different types of road vehicles (2019) Meccanica, 54 (9), pp. 1489-1497. , 2-s2.0-85070586381; Baker, C.J., The quantification of accident risk for road vehicles in cross winds (1994) Journal of Wind Engineering and Industrial Aerodynamics, 52, pp. 93-107. , 2-s2.0-0028431122; Xiang, H., Li, Y., Chen, S., Li, C., A wind tunnel test method on aerodynamic characteristics of moving vehicles under crosswinds (2017) Journal of Wind Engineering and Industrial Aerodynamics, 163, pp. 15-23. , 2-s2.0-85010903531; Batista, M., Perkovič, M., A simple static analysis of moving road vehicle under crosswind (2014) Journal of Wind Engineering and Industrial Aerodynamics, 128, pp. 105-113. , 2-s2.0-84898068464; Fuller, J., Best, M., Garret, N., Passmore, M., The importance of unsteady aerodynamics to road vehicle dynamics (2013) Journal of Wind Engineering and Industrial Aerodynamics, 117, pp. 1-10. , 2-s2.0-84877144010; Wang, L., (2014) Traffic Safety Study of Mountain Highway Bridge and Tunnel Connecting Segment under the Wind Environment, , Xi'an, China Chang'an University M.

During strong seismic actions, EB can be subjected to both axial and shear loads. The recent theoretical model [1] considers the effects of both loads to study large deformation stability of EB. The present paper investigates the accuracy of this theory by comparing the proposed results with numerical findings, aiming to extend the current linear elastic model with a more accurate non-linear advanced formulation that can consider the behaviour of elastomeric bearings captured by numerical findings. In particular, such improvement is necessary in designing strategic structures, such as bridges or nuclear power plants. The developed model may be implemented in existing Finite Element Model (FEM) platforms and be widely used by the practitioners. © 2020 European Association for Structural Dynamics.

The proposed motor combines a five-phase unipolar surface-mounted permanent-magnet (USPM) and a voice coil structure to simplify the motor structure, which motor can be named as rotary-linear surface-mounted permanent-magnet voice coil motor (RL-SVCM). And because of the characteristics of the rotary five-phase armature circuit and linear voice coil circuit, the proposed motor can provide low rotary ripple and smooth linear force. For designing the motor, the magnetic equivalent circuit (MEC) method is used to study the relationship between the linear force performance and motor structure parameters, and the effect of the flux bridges on the linear force and rotary torque. Due to uncertain variables in MEC, the FEM method is used to analyze the precise output result of rotary torque and linear force, and non-interaction between rotary and linear motions. © 2013 IEEE.","Rotary-linear motor; two-degree-of-freedom motion; voice coil motor (VCM)","Electric network analysis; Equivalent circuits; Permanent magnets; Position control; Air gap structures; Armature circuits; Magnetic equivalent circuit method; Rotary-linear motors; Structure parameter; Surface-mounted permanent magnet; Uncertain variables; Voice coil motors; Linear motors",,,,,"Ministry of Trade, Industry and Energy, MOTIE; National Research Foundation of Korea, NRF; Korea Institute of Energy Technology Evaluation and Planning, KETEP: 20154030200730","This work was supported in part by the Ministry of Trade, Industry and Energy, South Korea, through the Human Resources Program in Energy Technology of the Korea Institute of Energy Technology Evaluation and Planning (KETEP), under Grant 20154030200730; and in part by the National Research Foundation of Korea through the BK21PLUS Program within the Ministry of Education.",,,,,,,,,,"Zheng, Y., Duan, J., Materials and fabrication issues of micro V-groove for optoelectronics packaging (2011) Adv.

Likewise, we have also developed suitable materials with high thixotropy for layered extrusion and the gantry 3D-printing system, dealing with discontinuous geometry and multi-productions simultaneously. In this way, there have been a lot of studies particularly on material properties and printing processes so far. However, few studies have conducted structural performance testing on a large scale in a systematic manner. Hence, this structural concern is focused on and tackled in this study. The developed materials and printing system are used for the following experiments. As a preliminary test, specific characteristics such as anisotropy and creep of a layer-by-layer component are investigated for a structural design in addition to basic fresh and hardened properties. After the rational geometry is determined by topology optimization analysis, in which a practical scale pedestrian bridge under sidewalk loading is designed, its structural performance is evaluated for safety based on FEM (Finite Element Method) analysis, while considering the preliminary tests. The designed bridge structure consists of 44 segments with different complex shapes, which are printed separately, and all the segments are unified as a compression loaded structure through prestressed external reinforcement. Finally, it is confirmed whether the inherent behavior due to the laminar structure is observable in the full-scale bending test. © 2020, RILEM.","Anisotropy; Creep; Prestressed external reinforcement; Structural performance; Topology optimization method",,,,,,,,,,,,,,,,,"Kinomura, K., 3D-printing challenge with cementitious material Extended Abstracts of 1st International Conference on Concrete and Digital Fabrication, Digital Concrete 2018, Zurich, Switzerland, 10–12 September 2018, pp. 98-99. , (2018); Kinomura, K., Development of 3D-printing method for construction and its expectation toward the future (in Japanese) Annual Convention of Construction Technique on Civil Engineering, Japan Society of Civil Engineers, Technical Committee of Construction, Tokyo, Japan, 12 November 2019, pp. 69-75. , (2019); Asprone, D., Menna, C., Boss, F.P., Rethinking reinforcement for digital fabrication with concrete (2018) Cem.

Research in vibration-based damage identification has been rapidly expanding over the last few decades. The basic idea behind this technology is that modal parameters (notably frequencies, mode shapes, and modal damping) are functions of the physical properties of the structure (mass, damping, and stiffness). Therefore, changes in the physical properties will cause changes in the modal properties which could be obtained by structural health monitoring (SHM). Updating is a process fraught with numerical difficulties. These arise from inaccuracy in the model and imprecision and lack of information in the measurements, mainly taken place in joints and critical points. The motivation for the development of this technology is presented, methods are categorized according to various criteria such as the level of damage detection provided from vibration testing, natural frequency and mode shape readings are then obtained by using modal analysis techniques, which are used for updating structural parameters of the associated finite element model. The experimental studies for the laboratory tested bridge model show that the proposed model updating using ME'scope technique can provide reasonable model updating results. © 2020 Tech Science Press.

The test plate with diameter D = 300 mm has holes arranged at ten different radial spacings. The plate has holes with diameter d1 = 3.5 mm on the first inner circle, and holes on the tenth outside circle have a diameter d10 = 20.5 mm. The plate of the above geometry was free supported and loaded with different values of concentrated force. By means of numerical calculations using the finite element method, the coordinates of equivalent (von Mises) stress concentration zones in the perforated plate were determined. These zones were located on the plate bridges between perforation holes. The most hazardous place in the analysed perforated plate is associated with the outer circle, Z10, with the hole radius d1 = 3.5 mm at the circle radius R1 = 22.5 mm, where the highest stress concentration occurs. In this zone, the equivalent (von Mises) stress is σred max = 416.90 MPa (point with the coordinates x, y, z [mm], i.e. P10 [-69.9; 72.5; 0.0]).

First, the determination and implementation processes of reasonable completion state were introduced briefly, taking the Hunan Road Bridge as the background project, which is the widest concrete self-anchored suspension bridge in China currently. Then, the ANSYS beam-type finite element model and field monitoring data were integrated to investigate the cable system evolutions during system transformation. Finally, the global refined finite element model was established using solid element to consider the shear lag effects in extra-wide girder. The measured data show that the cable displacements in tensioned domains were characterized by weak coherence and contraflexure characteristics. The longitudinal and transverse stresses of extra-wide girder distributed unevenly along transverse direction. The maximum shear lag coefficients of girder at completion state reached to 1.3. Moreover, small transverse compressive stress, or even the transverse tensile stress reaching to 1.80 MPa, appeared in the top plate segments. The measures including the arrangement optimization of transverse prestressed tendons and monitoring point redistribution were given. The research can provide references for the structural designing and safety control of the similar bridges. © The Author(s) 2019.","concrete shrinkage and creep; extra-wide girder; safety evaluation; Self-anchored suspension bridge; shear lag; spatial behavior; system transformation","Cables; Concrete testing; Fiber optic sensors; Finite element method; Metadata; Shear flow; Shrinkage; Suspension bridges; Suspensions (components); Concrete shrinkage and creeps; Safety evaluations; Self-anchored suspension bridge; Shear lag; Spatial behaviors; system transformation; Concrete beams and girders",,,,,"cstc2017jcyjAX0187; 2011Y03; 12KJB560003, 51708074; National Natural Science Foundation of China, NSFC: 51278104; Fundamental Research Funds for the Central Universities: 30919011246; Chongqing Basic and Frontier Research Project; Specialized Research Fund for the Doctoral Program of Higher Education of China, SRFDP: 20133204120015","The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: The authors gratefully acknowledge the supports of Fundamental Research Funds for the Central Universities (No. 30919011246), National Natural Science Foundation of China (No. 51278104), Transportation Scientific Research Program of Jiangsu Province, China (No. 2011Y03), Research Fund for the Doctoral Program of Higher Education of China (No. 20133204120015), Universities Natural Science Foundation of Jiangsu Province, China (No. 12KJB560003), National Natural Science Foundation of China (No. 51708074), and Key Project of Foundation and Frontier Research of Chongqing (No. cstc2017jcyjAX0187).","In this study, we focused on the spatial mechanics characteristics of the self-anchored suspension bridge with extra-wide concrete girder during girder erection and system transformation. The numerical simulation and field monitoring for the Hunan Road Bridge, which is the widest concrete self-anchored suspension bridge in China currently, were integrated. Moreover, the global refined FE model was established using the solid element. The longitudinal and transverse stress evolutions of extra-wide girder during the whole construction process were studied. The significant contributions are summarized as follows: The maximum values of vertical and longitudinal cable displacements during the initial tensioning state reached to 0.603 and 0.189 m, respectively. The cable displacement was characterized by significant geometric nonlinear feature. The displacements of cable segments within the tensioned domains were characterized by weak coherence and contraflexure characteristics during side-span passive tensioning stages when the bridge has been provided with certain stiffness. Correspondingly, the hangers closest to the tensioned hanger were unloaded, while the internal forces of the farther hangers increased. The adjacent influence law of cable system can be utilized to optimize the hanger tensioning scheme considering the material strength limits of hanger and clamp. The compression-only link element has difficulty to produce convergent calculation results in simulating the scaffold system. Moreover, the calculation errors brought by the simulation method of cable system adopting the equivalent load application method were avoided. The results showed that the extra-wide girder plates at sections C7 and C2 were characterized by the negative and positive shear lag effects after the transverse and longitudinal prestress tensioning processes, respectively. The extra-wide girder was characterized by positive shear lag effect at the end of each hanger tensioning stage and bridge completion state. In addition, the shear lag coefficients of sections C7 and C2 at bridge completion state were within the ranges of 0.8–1.2 and 0.8–1.3, respectively. The transverse stress of girder basically did not change during the longitudinal prestress tensioning process and system transformation. In addition, the transverse compressive stress of the top plate close to road centerline at section C7 was relative small, which was only −1.0 MPa. Moreover, the transverse tensile stress appeared in the top plate at the injunction with outside web, which reached to 1.80 MPa. The arrangement and shapes of the transverse prestressed tendons in top plate should be optimized during the design processes for the similar bridges. The measuring points for the transverse girder stress of top plate at the injunctions with outside web and the road centerline of mid-span should be increased during the establishment of health monitoring system. The changes in the transverse girder stress should be monitored tightly during the uninstallation of girder scaffolds, which are the lessons learned from this article.

Using heterogeneous data can provide useful information to improve parameter identifiability in FEMU. It is worth noting that the useful information from the heterogeneous data may be diluted in the conventional FEM framework. The conventional FEMU framework in previous studies have used heterogeneous data at once to compute residuals in the objective function, and they are condensed to be a scalar. In this implementation, it should be careful to formulate the objective function with proper weighting factors to consider the scale of measurement and relative significances. Otherwise, the information from heterogeneous data cannot be efficiently utilized. For FEMU of the bridge, parameter compensation may exist due to mutual dependence among updating parameters. This aggravates the parameter identifiability to make the results of the FEMU worse. To address the limitation of the conventional FEMU method, this study proposes a sequential framework for the FEMU of existing bridges. The proposed FEMU method uses two steps to utilize static and dynamic data in a sequential manner. By using them separately, the influence of the parameter compensation can be suppressed. The proposed FEMU method is verified through numerical and experimental study. Through these verifications, the limitation of the conventional FEMU method is investigated in terms of parameter identifiability and predictive performance. The proposed FEMU method shows much smaller variabilities in the updating parameters than the conventional one by providing the better predictions than those of the conventional one in calibration and validation data. Based on numerical and experimental study, the proposed FEMU method can improve the parameter identifiability using the heterogeneous data and it seems to be promising and efficient framework for FEMU of the existing bridge. © 2019 by the authors.

For this aim, the finite element method analysis results of three closure methods were compared with experimental test results. Also, three more closure techniques are simulated numerically to study the effect of the number of wires used in the manubrium and xiphoid regions. A three-dimensional model of polyurethane sternum foam was created based on computed tomography images. Six different closure techniques using steel wire, steel bands and ZipFix bands were modeled on the sternum and transferred into a three-dimensional finite element model. The sternum was modeled as an isotropic bilinear-elasto-plastic material, and nonlinear contact conditions were applied. The models were analyzed under lateral distraction loading, and load-displacement curves were obtained from displacements at the incision line. Allowable loads and stiffness values of the methods were evaluated from these curves. The results showed the importance of the including material as well as geometric nonlinearities in the simulations to obtain realistic results from the numerical analyses. Also, the analyses showed that closures that include steel or ZipFix bands are superior to conventional wiring, and addition of a single wire at the manubrium and xiphoid regions significantly improved the efficiency of the closure techniques. © IMechE 2019.","biomechanics; image processing; median sternotomy; nonlinear finite element analysis; Sternum closure methods; thoracic surgery","Biomechanics; Composite bridges; Computerized tomography; Image processing; Nonlinear analysis; Wire; Computed tomography images; Finite element method analysis; Geometric non-linearity; Median sternotomy; Non-linear finite-element analysis; Sternum closure methods; Thoracic surgery; Three dimensional finite element model; Finite element method; anatomic model; anatomy and histology; biomechanics; diagnostic imaging; finite element analysis; nonlinear system; sternum; surgery; suture technique; weight bearing; x-ray computed tomography; Biomechanical Phenomena; Finite Element Analysis; Models, Anatomic; Nonlinear Dynamics; Sternum; Suture Techniques; Tomography, X-Ray Computed; Weight-Bearing",,,,,,,,,,,,,,,,"Dieselman, J.C., (2011) Comparison of alternative rigid sternal fixation techniques, , Worcester Polytechnic Institute, Worcester, MA, MS Thesis; Cheng, W., Cameron, D.E., Warden, K.E., Biomechanical study of sternal closure techniques (1993) Ann Thorac Surg, 55 (3), pp. 737-740; Serry, C., Bleck, P.C., Javid, H., Sternal wound complications, management and results (1980) J Thorac Cardiovasc Surg, 80 (6), pp. 861-886; Hendrickson, S.C., Koger, K.E., Morea, C.J., Sternal plating for the treatment of sternal nonunion (1996) Ann Thorac Surg, 62 (2), pp. 512-518; Zacharias, A., Habib, R.H., Factors predisposing to median sternotomy complications: deep vs superficial infection (1996) Chest, 110 (5), pp. 1173-1178; Trumble, D.R., McGregor, W.E., Magovern, J.A., Validation of a bone analog model for studies of sternal closure (2002) Ann Thorac Surg, 74 (3), pp. 739-744; Di Marco, R.F., Lee, M.W., Bekoe, S., Interlocking figure-of-8 closure of the sternum (1989) Ann Thorac Surg, 47 (6), pp. 927-929; Casha, A.R., Yang, L., Kay, P.H., A biomechanical study of median sternotomy closure techniques (1999) Eur J Cardio-Thorac, 15 (3), pp. 365-369; Khasati, N., Sivaprakasam, R., Dunning, J., Is the figure-of-eight superior to the simple wire technique for closure of the sternum?

In the present study, a preliminary forensic analysis of this incident was carried out using limited evidence collected from the collapse scene videos recorded by bystanders. This study is limited in its scope in that it is confined to the examination of how the sequence of failures unfolded by interpreting the rough measurements extracted from the videos through the prism of a physics-based (finite element) model of the bridge. The study does not attempt to explore why this incident may have happened. Nevertheless, by identifying how the collapse occurred, it may be possible to better understand the root causes of this unfortunate incident by combining this information with other, more detailed forensic data.

The live load distribution for continuous concrete multicell box-girder bridges varies according to bridge configuration, so when designing such bridges, it is important to determine the maximum negative stress at the piers, the midspan positive (tensile) stress and the deflection of the bridge when subjected to live loads. This paper reports an extensive parametric study to determine the maximum stress, deflection, and moment distribution factors for two span multicell box-girder bridges based on a finite element analysis of 120 representative numerical model bridges. Bridge parameters were selected to extend the parameters and ranges of current live load distribution factors defined by AASHTO LRFD specifications. The results indicate that the span length, number of boxes, and the number of lanes all significantly affect the positive (tensile) and the negative (compression) stress distribution factors.

Four loading modes including single load, double load, four-load, and twenty-load were simulated in a finite element analysis to observe their influence on ground vibrations. Four load moving speeds of 60, 80, 100, and 120 m/s were adopted to investigate the influence of train speed to the ground vibrations. The results demonstrated that the loading mode in a finite element analysis is reliable for train-induced vibration simulations. Additionally, a three-dimensional finite element model (3D FEM) was developed to investigate the dynamic responses of a track-ballast-embankment-ground system subjected to moving loads induced by high-speed trains. Results showed that vibration attenuations and breaks exist in the simulated wave fronts transiting through different medium materials. These tendencies are a result of the difference in the Rayleigh wave speeds of the medium materials relative to the speed of the moving train. The vibration waves induced by train loading were greatly influenced by the weakening effect of sloping surfaces on the ballast and embankment. Moreover, these tendencies were significant when the vibration waves are at medium and high frequency levels. The vibration waves reflected by the sloping surface were trapped and dissipated within the track-ballast-embankment-ground system. Thus, the vibration amplitude outside the embankment was significantly reduced. © 2019 Techno-Press, Ltd.","Fast Fourier transform; Finite element model; Moving train load; Track-embankment-ground system; Vibration response","3D modeling; Ballast (railroad track); Composite bridges; Dynamic response; Embankments; Fast Fourier transforms; Geometry; Railroad cars; Railroad transportation; Railroads; Speed; Vibration analysis; Wavefronts; Dynamic response analysis; Finite-element approach; Ground systems; Medium and high frequencies; Moving train; Three dimensional finite element model; Three dimensional finite elements; Vibration response; Finite element method",,,,,"National Natural Science Foundation of China, NSFC: 51438004, 51908152, 51908153; Guangzhou Science and Technology Program key projects: 201904010278; National Basic Research Program of China (973 Program): 2016YFC0800205","A part of the work was supported by National Key Research and Development Program of China (2016YFC0800205), National Natural Science Foundation of China (51908152, 51908153, Key Project 51438004), Guangzhou city Technology and Science Program (201904010278).",,,,,,,,,,"Auersch, L., The effect of critically moving loads on the vibrations of soft soils and isolated railway tracks (2008) J.

In order to understand the influence of this initial stress on the strength of the concrete-filled steel tubular arch bridge, a total of four single tubular arch rib (bare steel first) specimens (concrete-filled steel tubular last) with various initial stress levels were constructed and tested to failure. The test results indicate that the initial stress has a large influence on the ultimate load-carrying capacity and ductility of the arch structure. The high preloading ratio will reduce significantly the strength and ductility that the maximum reductions are over 25%. Then, a finite element method was presented and validated using the test results. Based on this finite element model, a parametric study was performed that considered the influence of various parameters on the ultimate load-carrying capacity of concrete-filled steel tubular arches. These parameters included arch slenderness, rise-to-span ratio, loading method, and initial stress level. The analysis results indicate that the initial stress can reduce the ultimate loading capacity significantly, and this reduction has a strong relationship with arch slenderness and rise-to-span ratio. Finally, a method for calculating the preloading reduction factor of ultimate load-carrying capacity of single concrete-filled steel tubular arch rib structures was proposed based on the equivalent beam–column method. © The Author(s) 2019.","arch rib;

The structural stress approach is an important approach for fatigue life evaluation of welded structures. Firstly, two parameters and the mesh sensitivity of the stress-based integration equivalent structural stress approach (stress integration approach for short) are analyzed in this paper. Then, the applicability of the master S-N curve is verified based on experimental data of the deck-rib welding details in OSDs. Finally, the multi-scale finite element model (FEM) of Jiangyin Bridge is established, and the bridge fatigue life calculation steps based on the stress integration approach are given. The influence of the slope of the master S-N curve at high cycles on the bridge fatigue life is discussed. Further, the weld parameter influences on the bridge fatigue life are analyzed, as including the following: (1) The determination of the influence of the weld size changes caused by weld manufacturing errors on the bridge fatigue life; (2) the proposal of a new grinding treatment type, and the analysis of influence of the grinding radius on fatigue life; and (3) a comparison of the fatigue life of the deck-rib welding details under 80% partial penetration and 100% full penetration. The results show that the structural stress calculated by the stress integration approach does not change significantly with the parameters of the isolation body width w and the distance δ between the crack propagation surface and the reference surface. To simplify the calculation, δ is set as 0, and w can be set as the mesh size along the weld length direction. The mesh size of the stress integration approach is recommended as 0.25 times the deck thickness. The slope of the master S-N curve at high cycles significantly affects the bridge fatigue life, and a slope of 5 is reasonable. The weld parameter studies for the deck-rib welding details in the OSD of Jiangyin Bridge show that the change of weld size caused by manufacturing errors can obviously affect the bridge fatigue life, and the fatigue life of five different weld types varies from 51 years to 113 years. The new grinding treatment type, without weakening the deck, is beneficial to improving the bridge fatigue life. The fatigue life increases by approximately 5% with an increase of the grinding radius of 2 mm. The fatigue life of 80% partial penetration is slightly higher than that of 100% full penetration. © 2019 by the authors.","Deck-rib; Equivalent structural stress; Fatigue evaluation; Grinding treatment; Master S-N curve; Penetration rate; Steel bridge; Weld size",,,,,,"KYLX16_0250; National Natural Science Foundation of China, NSFC: 51438002, 51578138, 51608258; National Key Research and Development Program of China, NKRDPC: 2015CB060000; Fundamental Research Funds for the Central Universities: 2242016K41066; Priority Academic Program Development of Jiangsu Higher Education Institutions, PAPD: 1105007002","The authors gratefully acknowledge the National Basic Research Program of China (973 Program) (no. 2015CB060000), the Key Program of National Natural Science Foundation (no. 51438002), the Program of National Natural Science Foundation of China (no. 51578138, 51608258), the Fundamental Research Fund for the Central Universities (no. 2242016K41066), the Fundamental Research Funds for the Central Universities and graduates' Science and Innovation Foundation of Jiangsu Province (no.

In order to investigate the flexural behavior of the composite beams, four-point bending tests and push-out tests were conducted. First, GFRP-concrete-steel composite beams with different interface types were fabricated and tested. Experimental results indicated the concrete ultimate strain and the ultimate deflection were increased because of the confining effect provided by GFRP plates. The GFRP-concrete interface had no obvious effect on flexural stiffness and flexural capacity. The slip effect of GFRP-concrete-steel beams was similar to that of steel-concrete beams. The failure process of GFRP-concrete-steel beams was different from that of steel-concrete beams due to the effect of the GFRP plate. Then, push-out specimens were tested to investigate the slip effect between GFRP-concrete decks and steel beams. The effect of GFRP plates on the studs was insignificant because of the large stud hole, and a regression formula of load-slip relationship was presented based on the experimental results. Finally, finite element model and theoretical model were employed to analyze the deflection calculation method and the flexural capacity calculation method, respectively. © 2019, Korean Society of Civil Engineers.","composite beam; confining effect; finite element; flexural capacity; GFRP-concrete; stud shear connector","Bending tests; Composite beams and girders; Concrete beams and girders; Concrete testing; Fiber reinforced plastics; Finite element method; Shear flow; Steel beams and girders; Steel fibers; Steel testing; Studs (fasteners); Studs (structural members); Composite beam; Confining effect; Deflection calculations; Flexural capacity; Four-point bending test; Glass fiber reinforced polymer; Stud shear connector; Theoretical modeling; Reinforced concrete",,,,,"271400140114","The authors would like to express their acknowledgments to the financial support provided by China Communications Construction Company Ltd.

However, existing conventional SFPMM utilizes more Permanent Magnet (PM) volume results in overall increase of machine cost and weight. Moreover, high PM usage enhance interaction with rotor core that ultimately generate cogging torque (no load torque) which introduce vibration and acoustic noise. In additional, conventional SFPMM exhibits flux leakages from the PMs end which effects electromagnetic performance. In this paper, a novel consequent pole SFPMM (CPSFPMM) with flux bridges, flux barriers and reduced partition PMs is introduced which leads in reduction of total machine cost, weight and decrease of the cogging torque. Moreover, rotor pole analysis is carried out for optimal combination of the rotor poles number combination for initial optimal design of CPSFPMM with key performance indicators such as open-circuit flux linkage, cogging torque, mechanical torque, Total harmonic distortion (THD), torque ripple ratio, average torque and average power characteristics. Based on Finite Element Analysis (FEA) on commercial FEA package JMAG v. 14, CPSFPMM with 12-stator slot and 13 rotor poles is searched out to be optimal design with comparatively best electromagnetic performance. Moreover, proposed novel CPSFPMM is compared with existing conventional SFPMM. Analysis reveals that proposed CPSFPMM utilized 77% PM volume, which reduce machine cost, weight, and offer 124.06% peak to peak open-circuit flux linkage, 52.74% peak to peak cogging torque, 99.2% average torque, 34.67% THD and 77.64% torque ripple ratio when compared with existing conventional SFPMM. © 2019 IEEE.","AC Machines; Consequent Pole; Finite Element Analysis; Flux Switching; Low cost; Permanent Magnet; Rotor pole combination","AC machinery; Acoustic noise; Benchmarking; Cost benefit analysis; Cost reduction; Finite element method; Optimal systems; Torque; AC machine; Consequent-pole; Flux-switching; Low costs; Rotor poles; Permanent magnets",,,,,,,,,,,,,,,,"Zhu, Z.Q., Switched flux permanent magnet machines-Innovation continues (2011) Proc.

They are employed for bridges as well, but their application in this respect is limited. BRBs can also be used as a function of the individual damper rather than the structural component or the bracing, in which case the device may be called a Buckling Restrained Damper (BRD). Yet, such application has not been explored much. There are quite a few bridges designed according to the old design codes in Japan. Their seismic resistance may not be satisfactory for the current seismic design codes. Against this background, the behavior of a steel truss bridge under a large seismic load was investigated by nonlinear dynamic finite element analysis. Some members were indeed found to be damaged in the earthquake. Retrofitting is needed. To this end, the application of BRD was tried in the present study: a parametric study on the seismic behavior of the truss bridge with BRD was conducted by changing the length, the cross-sectional area, the location and the inclination of BRD. The effectiveness of BRD was then discussed based on the numerical results thus obtained. In all the analyses, ABAQUS was used. © 2019 by the authors.","Buckling restrained damper; Energy absorption; Nonlinear dynamic analysis; Retrofit; Seismic behavior; Truss bridge",,,,,,,"Acknowledgments: P.S. thanks to Mongolia-Japan higher Engineering Education Development project (MJEED), the Government of Mongolia for the financial support.",,,,,,,,,,"Jun-ichi, H., Guangfeng, Z., Performance of seismic retrofitted highway bridges based on observation of damage due to the 2011 Great East Japan Earthquake (2013) J.

Hollow reinforced-concrete bridge columns have been used in the past in place of their solid counterparts in the construction of bridges. These hollow columns have several benefits over solid columns, including the reduction of vertical load applied to the foundation as well as the reduction of seismic mass. Two circular and two rectangular hollow reinforced-concrete bridge columns were tested under a constant axial load and a cyclically reversed horizontal load. A computer program, RCAHEST (Reinforced Concrete Analysis in Higher Evaluation System Technology), is used to analyse reinforced-concrete structures. Novel damage indices aim to provide a means of quantifying numerically the performance level in cast-in-place and precast hollow reinforced-concrete bridge columns sustained under earthquake loading. The proposed numerical method for the seismic performance assessment of hollow reinforced-concrete bridge columns is verified by comparison with the experimental results. © 2018 ICE Publishing: All rights reserved.","finite element methods; modelling; structural analysis","Columns (structural); Concrete bridges; Damage detection; Finite element method; Models; Numerical methods; Railroad bridges; Reinforced concrete; Seismic design; Seismic waves; Seismology; Structural analysis; Design criteria; Earthquake loadings; Hollow columns; Horizontal loads; Performance level; Reinforced concrete bridge columns; Seismic Performance; Seismic performance assessment; Cast in place concrete",,,,,,,,,,,,,,,,"(2012) AASHTO LRFD Bridge Design Specifications, , 6th edn.

Göderni historical masonry two-span arch bridge which is located in Kulp town, Diyarbakır, Turkey is selected as a numerical application. The bridge takes part in bowless bridge group and built in large measures than the others. The restoration projects were approved and rehabilitation studies have still continued. Finite element model of the bridge is constituted with special software to determine the static and dynamic behavior. To demonstrate the arch curvature effect, the finite element model are reconstructed considering different arch curvature between 2.86 m-3.76 m for first arch and 2.64 m-3.54 m for second arch with the increment of 0.10 m, respectively. Dead and live vehicle loads are taken into account during static analyses. 1999 Kocaeli earthquake ground motion record is considered for time history analyses. The maximum displacements, principal stresses and elastic strains are compared with each other using contour diagrams. It is seen that the arch curvature has more influence on the structural response of historical masonry arch bridges. At the end of the study, it is seen that with the increasing of the arch heights, the maximum displacements, minimum principal stresses and minimum elastic strains have a decreasing trend in all analyses, in addition maximum principal stresses and maximum elastic strains have unchanging trend up to optimum geometry. © 2019 Techno-Press, Ltd.","Arch bridge; Curvature effect; Dynamic behavior; Finite element model; Masonry","Arches; Earthquakes; Elasticity; Finite element method; Masonry bridges; Masonry construction; Masonry materials; Soil structure interactions; Static analysis; Strain; Structural design; Curvature effect; Dynamic behaviors; Earthquake ground motions; Masonry; Maximum principal stress; Numerical applications; Static and dynamic behaviors; Time history analysis; Arch bridges",,,,,,,,,,,,,,,,"Altunisik, A.C., Bayraktar, A., Genc, A.F., Determination of the restoration effect on the structural behavior of masonry arch bridges, Smart Struct (2015) Syst., 16 (1), pp. 101-139. , https://doi.org/10.12989/sss.2012.10.2.131; Altunisik, A.C., Bayraktar, A., Genc, A.F., A study on seismic behaviour of masonry mosques after restoration (2016) Earthq.

A new PC deck system was developed and implemented in the construction of the Kearney East Bypass project in Nebraska. The new system consists of full-depth full-width PC panels with covered shear pockets to minimize deck surface penetrations and eliminate deck overlay. Deck panels are pretensioned in the transverse direction and posttensioned in the longitudinal direction using a new approach that is ductless and easy to install. The study presents the live load testing of the twin bridges constructed in that project: the southbound bridge constructed using CIP concrete deck and the northbound bridge constructed using the new system. Two loaded trucks were used to evaluate and compare the performance of the two deck systems. Relative displacements between adjacent deck panels, and between deck panels and girders, were measured. Testing results indicated that the new system behaves as fully composite with the girders, and its posttensioned system is satisfactory. Finite-element analysis (FEA) was conducted to model the new deck system and compare measured and predicted strains and deflections. © 2019 American Society of Civil Engineers.","Bridge; Composite; Concrete; Deck-panel; Finite-element analysis (FEA); Live load test; Precast","Bridge decks; Bridges; Composite materials; Concretes; Finite element method; Load testing; Precast concrete; Bridge constructions; Construction duration; Deck panel; Live loads; Longitudinal direction; Pre-cast; Relative displacement; Surface penetration; Cast in place concrete",,,,,"Nebraska Department of Transportation, Nebraska DOT","The research project was sponsored by Nebraska DOT (NDOT).

Hot-rolled profiles are generally resistant to local buckling; however, long-term exposure to the aggressive environment of a mine shaft leads to high corrosive loss of the material and reduction of the wall thickness. Some industrial regulations on shaft steelwork design and maintenance allow more than 50% corrosion loss for guides; however, they do not require local buckling calculations. This study investigated the buckling resistance of box-section beams welded from hot-rolled channel sections under bending, in terms of uniform corrosion loss. Laboratory bending tests were conducted on five beams for three levels of web thickness reduction achieved by etching and the results were compared with those obtained from finite element (FE) simulations. Linear modal analyses and nonlinear Riks simulations with imperfections were performed. The hot-rolled box-sections, which are generally resistant to local buckling, were found to be susceptible to local buckling at 46 and 60% corrosion losses in the plastic state and at 71% corrosion loss in the elastic state. This study highlights the need to consider local buckling when using hot-rolled closed profile beams at high corrosion loss. © 2019 Elsevier Ltd","Bending test; Corroded profile; FEM analysis; Hot-rolled profiles; Local buckling","Bending tests; Box girder bridges; Composite beams and girders; Corrosion; Mine shafts; Modal analysis; Welding; Aggressive environment; Buckling resistance; Corroded profile; FEM analysis; Finite element simulations; Hot-rolled; Local buckling; Long term exposure; Hot rolled steel",,,,,,,,,,,,,,,,"(2005) EN-1993-1-1 Eurocode 3: design of steel structures - Part 1-1: general rules and rules for buildings; AISC, Specification for Structural Steel Buildings (2016), American Institute of Steel Chicago ANSI/AISC 360-16; (2008) BS 5950-1:2000 structural use of steelwork in building.

Thermal ground plane (TGP), known as vapor chamber or two-dimensional flat heat pipe, is a promising solution for the thermal management of foldable smartphones. There are two approaches to designing a TGP for foldable smartphones. One approach uses two TGPs connected by a graphite bridge and the other approach uses a single, large, and foldable TGP. In this study, different thermal management solutions are simulated for a representative foldable smartphone with screen dimensions of 144 × 138.3 mm2 (twice the screen of iPhone 6 s with a 10 mm gap). In addition, the simulation includes two heat sources representing a main processor with dimensions of 14.45 × 14.41 mm2 and power of 3.3 W (A9 processor in iPhone 6S) and a broadband processor with dimensions of 8.26 × 9.02 mm2 and power of 2.5 W (Qualcomm broadband processor). For the simulation, a finite element method (FEM) model is calibrated and verified by steady-state experiments of two different TGPs. The calibrated model is then used to study three different cases: a graphite heat spreader, two TGPs with a graphite hinge, and a single, large, and foldable TGP. In the fully unfolded configuration, using a graphite heat spreader, the temperature difference across the spreader's surface is about 17 °C. For the design using two TGPs connected by a graphite bridge, the temperature difference is about 7.2 °C. Finally, for the design using a single large TGP with a joint region, the temperature difference is only 1-2 °C. These results suggest that a single foldable TGP or a configuration with two TGPs outperform the graphite sheet solution for the thermal management of foldable smartphones. © 2019 by ASME.",,"Graphite; Heat pipes; Heating equipment; Integrated circuit design; Smartphones; Spreaders; Temperature control; Broadband processors; Calibrated model; Finite element method model (FEM); Flat heat pipe; Graphite sheets; Heat spreaders; Screen dimensions; Temperature differences; Thermal management (electronics)",,,,,"University of Colorado Boulder","This research is supported by Kelvin Thermal Technologies, Inc., through a gift account established at the University of Colorado Boulder.",,,,,,,,,,"Seo, K., Ryu, S., (2018) International Patent Application, , Patent No; Seo, K., Ryu, S., Hyun, J., Lee, J., (2017) Tablet Computer, , U.S. Patent No; Zhang, Z., Yin, V.H., Liu, C.Y., Drzaic, P.S., Bae, S., Tung, C.H., Vakhshouri, K., Zhong, J.Z., (2017) Electronic Devices with Flexible Displays, , U.

The transformer size is largely reduced when operating at medium frequency compared with conventional power frequency transformer which provides the possibility for higher power density. However, there is a trade-off between the high power density and thermal performance. First of all, the exposed cooling surface is reduced accordingly. And the dissipated heat is proportional to the exposed cooling surface directly. Secondly with higher frequencies, effects such as skin and proximity and hysteresis losses are significantly increased compared to transformer operation at 50/60 Hz. Besides the design process should consider high isolation requirement. And this again defects the transformer thermal performance and this is because firstly insulation material adds extra losses to the system, secondly the construction of the insulation will block some cooling surfaces and thirdly those insulation materials normally have relatively low thermal conductivity. As a consequence, the thermal design should be carefully considered and evaluated. To solve this problem, only the high voltage side winding is impregnated in epoxy resin which reduces the insulation material. The stacked transformer cores are gapped from each other which have helped the transformer heat dissipation. Such that, a design with low thermal resistance and high power density is achieved. FEM models are developed to analyze the transformer electric and thermal performances. Finally prototypes are built and tested to verify our design concept. © 2019 The Korean Institute of Power Electronics (KIPE).","High voltage; Isolation design; Medium frequency transformer; Thermal analysis","Bridges; Cooling; DC-DC converters; Design; Economic and social effects; Electric inverters; Electric windings; Epoxy resins; HVDC power transmission; Insulating materials; Power electronics; Thermal conductivity; Thermal insulation; Thermoanalysis; Dual active bridges; High voltage; Insulation materials; Low thermal conductivity; Medium frequencies; Medium frequency transformer; Stacked transformer; Thermal Performance; DC transformers",,,,,,,,,,,,,,,,"Zhao, B., Song, Q., Liu, W., Sun, Y., Overview of dual-active-bridge isolated bidirectional DC-DC converter for high-frequency-link powerconversion system (2014) IEEE Trans.

Geometric parameters including cross-section shape, arch radius and number of arches were first optimised by the finite element (FE) method. A self-balancing prestressed basalt FRP (BFRP) shell system was proposed to resist the deformation under construction load and to enhance the integrated mechanical behaviour. The mechanical behaviour of the proposed FRP shell were examined under a simulated construction load. The stresses and deformations of the FRP shell were analysed during both prestress tensioning and construction loading. A static test was further conducted on the BFRP shell-concrete composited bridge deck to verify prestressing effect. The results show a corrugated cross-section with two arches on its lower flange further enhances the stiffness of FRP shell for a composite bridge deck. The prestressed FRP shell offsets the deformation under construction by the camber and exhibits more linear structural behaviour when compared to the non-prestressed BFRP shell. The stress monitored during loading indicates a superior integrated behaviour of the FRP shell and prestressing FRP laminates. Furthermore, the load-displacement relationship of prestressed composite bridge deck demonstrates a high loading capacity and small deflection at serviceability limit state. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.","Basalt fibre-reinforced polymer; composite bridge deck; construction load simulation; finite element method; optimisation; prestress","Arch bridges; Arches; Balancing; Basalt; Composite bridges; Concretes; Deformation; Fiber reinforced plastics; Finite element method; Polymers; Prestressing; Reinforced plastics; Reinforcement; Shells (structures); Stress analysis; Construction loading; Construction loads; Cross section shape; Fibre reinforced polymers; Mechanical behaviour; Optimisations; Serviceability limit state; Structural behaviour; Bridge decks",,,,,"National Natural Science Foundation of China, NSFC: 51508277, 51678139; Natural Science Foundation of Jiangsu Province: BK20150886","Science Foundation of China under Grant [numbers 51508277 and 51678139].","This work was supported by the Natural Science Foundation of Jiangsu Province under Grant [number BK20150886] and the National","This work was supported by the Natural Science Foundation of Jiangsu Province under Grant [number BK20150886] and the National Science Foundation of China under Grant [numbers 51508277 and 51678139].",,,,,,,,"(2004), Guide test methods for fiber reinforced polymers (FRPs) for reinforcing or strengthening concrete structures.

This paper presents an extensive study of stability performance during construction for the world longest steel truss deck cable-stayed bridge-Yachihe Bridge. Based on the finite element analysis, the Linear Elastic Stability (LES), Nonlinear Elastic Stability (NLES) and Nonlinear Inelastic Stability (NLIES) of the bridge have been investigated to identify the effects of geometry nonlinearity and material nonlinearity on the structural stability performance. In addition, the influences of temperature variations and static lateral winds on stability performance are also focused. The results show that: 1) Under design ambient temperature, the corresponding design of steel truss deck yields the minimum stability coefficients of LES, NLES and NLIES by 5.72, 4.64 and 2.96, respectively, corresponding to the completion of superimposed dead loads; 2) both the geometry nonlinearity and material nonlinearity have been identified to make negative effects on the stability performance and the material nonlinearity will reduce the structural stability coefficient largely; 3) during construction, the rise and drop in temperature will increase and decrease the stability coefficients, respectively. NLIES is the most sensitive one to variations of temperature; and 4) the lateral static winds slightly reduce the stability coefficients of LES, NLES and NLIES. © 2019, Korean Society of Civil Engineers.","cable-stayed bridge; geometry nonlinearity; material nonlinearity; stability analysis; static wind load; steel truss deck; temperature","Cables; Geometry; Stability; Temperature; Trusses; Design ambient temperatures; Long span cable stayed bridges; Material non-linearity; Non-linear elastic stability; Stability analysis; Static wind load; Steel truss; Structural stabilities; Cable stayed bridges",,,,,,,,,,,,,,,,"(2010), User manual version 13.0, ANSYS Inc., Canonsburg, USA; Bu, Y.Z., Zhao, L., Li, Q., Structural nonlinear stability analysis of Sutong Yangtze river bridge (2013) China Civil Engineering Journal, 46 (1), pp. 84-91; Chen, D.W., Li, C., Tan, M.J., Comparative analysis on structure of steel truss girder with steel box girder of super-longspan cable-stayed bridges (2017) China Civil Engineering Journal, 62 (3), pp. 84-90; Choi, D.H., Yoo, H., Shin, J.I., Park, S.I., Nogami, K., Ultimate behavior and ultimate load capacity of steel cable-stayed bridges (2007) China Civil Engineering Journal, 27 (4), pp. 477-499; Han, D.J., Zou, X.J., Nonlinear aerostatic stability analysis of a long span cable-stayed bridge (2005) China Civil Engineering Journal, 22 (1), pp. 206-210; Hassan, M.M., Nassef, A.O., Damatty, A.A.E., Determination of optimum post-tensioning cable forces of cable-stayed bridges (2012) Engineering Structures, 44 (6), pp. 248-259; Hastings, J.S., Zhao, Q.H., Burdette, E.G., Steel girder stability during bridge erection: AASHTO LRFD check on L/b ratios (2010) China Civil Engineering Journal, 15 (6), pp. 759-762; Kim, S., Won, D.H., Kang, Y.J., Ultimate behavior of steel cable-stayed bridges - I. rational ultimate analysis method (2016) China Civil Engineering Journal, 16 (2), pp. 601-624; Kim, S., Won, D.H., Kang, Y.J., Ultimate behavior of steel cable-stayed bridges - II. parametric study (2016) China Civil Engineering Journal, 16 (2), pp. 625-636; Kim, H.J., Won, D.H., Kang, Y.J., Kim, S., Structural stability of cable-stayed bridges during construction (2017) China Civil Engineering Journal, 17 (2), pp. 443-469; Kim, S., Won, D.H., Lee, K., Kang, Y.J., Structural stability of cable-stayed bridges (2015) China Civil Engineering Journal, 15 (3), pp. 743-760; Liu, Y., Qian, Z., Hu, J., Jin, L., Temperature behavior and stability analysis of orthotropic steel bridge deck during gussasphalt pavement paving (2018) China Civil Engineering Journal, 23 (1), p. 04017117; Miao, J.W., Xiao, R.C., Pei, M.S., Zhang, X.G., Summarized comparison study on global static stability of the Su-tong cable-stayed bridge (2006) China Civil Engineering Journal, 34 (7), pp. 869-873; Ren, W.X., Ultimate behavior of long-span cable-stayed bridges (1999) China Civil Engineering Journal, 4 (1), pp. 30-37; Shu, H.S., Wang, Y.C., Stability analysis of box-girder cable-stayed bridges (2001) China Civil Engineering Journal, 6 (1), pp. 63-68; Wang, P.H., Tang, T.Y., Zheng, H.N., Analysis of cable-stayed bridges during construction by cantilever methods (2004) China Civil Engineering Journal, 82 (4), pp. 329-346; Wu, J., Frangopol, D.M., Soliman, M., Geometry control simulation for long-span steel cable-stayed bridges based on geometricly nonlinear analysis (2015) China Civil Engineering Journal, 90 (2015), pp. 71-82; Xi, Y., Kuang, J.S., Ultimate load capacity of cable-stayed bridges (1999) China Civil Engineering Journal, 4 (1), pp. 14-22; Xi, Z., Xi, Y., Xiong, H., Ultimate load capacity of cable-stayed bridges with different deck and pylon connections (2014) China Civil Engineering Journal, 19 (1), pp. 15-33; Yoo, H., Na, H.S., Choi, E.S., Choi, D.H., Stability evaluation of steel girder members in long-span cable-stayed bridges by member-based stability concept (2010) China Civil Engineering Journal, 10 (4), pp. 395-410; Yu, X.M., Chen, D.W., Bai, Z.Z., Jin, B., Key techniques for construction of steel truss girder of Yachi River Bridge on Guiyang-Qian’xi expressway (2017) China Civil Engineering Journal, 47 (4), pp. 108-113; Yu, X.M., Chen, D.W., Xue, M.G., Yachihe bridge, China: Engineering the world’s longest cable-stayed steel truss (2018) China Civil Engineering Journal, 171 (1), pp. 29-36; Zhao, L., Sun, C.Z., Yang, X.W., Stability analysis of Edong Yangtze River Bridge during construction (2012) China Civil Engineering Journal, 47 (5), pp. 741-747","Bai, Z.-Z.; Dept. of Bridge Engineering, China; email: zzbai@tongji.edu.cn",,,"Springer Verlag",,,,,12267988,,,,"English","KSCE J.

During the overhang construction of the bridge, torsional loads are often induced due to the fresh concrete load and the use of a deck finishing machine located on the overhang formwork. These torsional moments sometimes cause excessive exterior girder rotation, resulting in many safety and maintenance issues during the construction and service stages. To prevent these issues, most states have specifications for limiting the rotation. Finite element analysis using shell or solid elements is usually recommended for analyzing bridge girders in overhang construction, which can be tedious and difficult in some cases. This study focused on developing a simple method with minimal calculation to evaluate the ratio of unbraced length to girder depth (B/D ratio). The stepwise variable selection method and a regression analysis were conducted to find the relationship between the exterior girder rotation and bridge geometries. A computer program for automatic finite element modeling in SAP2000 was developed using MATLAB, resulting in 4285 finite element models with different bridge geometries being developed to generate artificial data. By conducting a study of variable selection, three parameters were selected based on level of significance. After conducting a regression analysis based on the selected parameters, a method using the normal weight of girder, overhang width, and rotation limit to determine B/D ratio was developed. © 2019 Elsevier Ltd","Bridge deck construction; Exterior girder rotation; Finite element modeling; Parametric study; Regression analysis; Stepwise variable selection","Beams and girders; Bridges; MATLAB; Regression analysis; Rotation; Bridge deck construction; Finishing machines; Girder rotations; Parametric study; Simplified method; Three parameters; Variable selection; Variable selection methods; Finite element method; bridge construction; finite element method; loading test; numerical model; regression analysis; steel structure; United States",,,,,,,,,,,,,,,,"Clifton, S.P., Bayrak Oguzhan.

In the testing and simulating, the strong motion records with different frequency characteristics and durations, El Centro record from Ms6.7 Imperial Valley earthquake and Wolong record from Ms8.0 Wenchuan earthquake, were as the input motions. The dynamic property, vibration response, damage rule, and failure mode of the curved bridge were obtained preliminarily. The experimental results showed that the transverse stiffness of this soil-pile-bridge structure system was larger than the longitudinal stiffness; the obvious torsion effect of the model structure was observed in the tests under the input motion in uni-direction, and the larger was the input motion PGA, more obvious was the torsion effect; the seismic responses were more sensitive to input motions with relative low-frequency components; the damage degree of the pier bottom increased from short to high pier, and the rubber bearings at side piers appeared two different failure modes induced by the longitudinal slope. Compared with straight bridges, the curvature radius made curved bridges more prone to causing rotation and displacement. Furthermore, finite element analyses were conducted by using the plastic-damage model for concrete, and equivalent soil springs method for pile-soil interaction, respectively. The simulations were in agreement with the test results satisfactorily, moreover the differences between these results were discussed in detail and the errors were in an acceptable range. These studies would be used to provide insights for the further research and theoretical design of curves bridges. © 2018","Numerical simulation; Shaking table test; Small radius curved bridge; Soil-pile-structure interaction","Bridges; Computer simulation; Earthquakes; Finite element method; Numerical models; Piers; Soil structure interactions; Soil testing; Soils; Stiffness; Structural design; Torsional stress; Curved bridge; Longitudinal stiffness; Low-frequency components; Pile soil interaction; Plastic-damage models; Shaking table tests; Soil-pile-structure interactions; Strong motion records; Piles; bridge; computer simulation; earthquake damage; finite element method; numerical model; pile; shaking table test; Sichuan earthquake 2008; soil-structure interaction; strong motion; structural response; California; El Centro; Imperial Valley; United States",,,,,"National Natural Science Foundation of China, NSFC: 51421005; Beijing Municipal Natural Science Foundation: 8172049; National Key Research and Development Program of China, NKRDPC: 2017YFC1500400","This research is supported by the National Key Research and Development Program of China (No. 2017YFC1500400 ), Beijing Municipal Natural Science Foundation (No. 8172049 ) and the National Natural Science Foundation of China (No. 51421005 ).",,,,,,,,,,"Tseng, W.S., Penzien, J., Seismic analysis of long multiple-span highway bridges (1975) Earthq Eng Struct Dyn, 4 (1), pp. 1-24; Tseng, W.S., Penzien, J., Seismic response of long multiple-span highway bridges (1975) Earthq Eng Struct Dyn, 4 (1), pp. 25-28; Fenves, G.L., Ellery, M., Behavior and failure analysis of a multiple-frame highway bridge in the 1994 Northridge earthquake.

This paper analyses a series-series(SS) compensated IPT system using Boucherot bridge current source model to establish the relationship between magnetic pad parameters (mutual inductance) and power electronic system parameters (input and output voltages and currents). Analysis was used to design a 3.7 kW IPT system. The design is validated with the aid of finite element analysis software, ANSYS Maxwell and Simplorer. The proposed design is capable of transferring power at an efficiency of 95.88%. Furthermore, analysis shows that the mutual inductance requirement decreases with the increase in rated power for a SS compensated IPT system. © 2018 IEEE.","Boucherot bridge current source model; electric vehicles; finite-element modelling; inductive power transfer; series-series compensation","Automobile electronic equipment; Efficiency; Electric vehicles; Energy transfer; Inductance; Inductive power transmission; Power electronics; Critical performance indices; Current source modeling; Finite element analysis software; Finite element modelling; Inductive power transfer; Inductive powertransfer (IPT); Power electronic systems; Series compensation; Finite element method",,,,,"University of Cape Town","This work was supported by University of Cape Town and National Research Foundation of South Africa.",,,,,,,,,,"Hui, S.Y.R., Zhong, W., Lee, C.K., A critical review of recent progress in mid-range wireless power transfer (2014) IEEE Transactions on Power Electronics, 29 (9), pp. 4500-4511. , Sept; Bosshard, R., Kolar, J.W., Muhlethaler, J., Stevanovi, I., Wunsch, B., Canales, F., Modeling and $eta $ - $alpha $-pareto optimization of inductive power transfer coils for electric vehicles (2015) IEEE Journal of Emerging and Selected Topics in Power Electronics, 3 (1), pp. 50-64. , March; Sampath, J.P.K., Alphones, A., Vilathgamuwa, D.M., Figure of merit for the optimization of wireless power transfer system against misalignment tolerance (2017) IEEE Transactions on Power Electronics, 32 (6), pp. 4359-4369. , June; Lu, M., Ngo, K.D.T., A fast method to optimize efficiency and stray magnetic field for inductive-power-transfer coils using lumped-loops model (2018) IEEE Transactions on Power Electronics, 33 (4), pp. 3065-3075. , April; Icnirp guidelines for limiting exposure to time-varying electric magnetic and electromagnetic fields (1 Hz to 100 KHz) (2010) Health Phys., 99 (6), pp. 818-836. , International Commission on Non-Ionizing Radiation Protection, Dec; Zhang, W., Mi, C.C., Compensation topologies of high-power wireless power transfer systems (2016) IEEE Transactions on Vehicular Technology, 65 (6), pp. 4768-4778. , June; Safaee, A., Woronowicz, K., Time-domain analysis of voltage-driven series-series compensated inductive power transfer topology (2017) IEEE Transactions on Power Electronics, 32 (7), pp. 4981-5003. , July; Jiang, Y., Wang, L., Wang, Y., Liu, J., Li, X., Ning, G., Analysis, design and implementation of accurate ZVS angle control for EV's battery charging in wireless high power transfer IEEE Transactions on Industrial Electronics, PP (99), p. 1; Berger, A., Agostinelli, M., Vesti, S., Oliver, J.A., Cobos, J.A., Huemer, M., A wireless charging system applying phase-shift and amplitude control to maximize efficiency and extractable power (2015) IEEE Transactions on Power Electronics, 30 (11), pp. 6338-6348. , Nov; Woronowicz, K., Safaee, A., Dickson, T., Youssef, M., Williamson, S., Boucherot Bridge based zero reactive power inductive power transfer topologies with a single phase transformer (2014) 2014 IEEE International Electric Vehicle Conference (IEVC), pp. 1-6. , Florence; Kim, H., Coil design and measurements of automotive magnetic resonant wireless charging system for high-efficiency and low magnetic field leakage (2016) IEEE Transactions on Microwave Theory and Techniques, 64 (2), pp. 383-400. , Feb; Wireless Charging of Electric and Plug-in Hybrid Vehicles, , http://standards.sae.org/wip/j2954/, Society of Automotive Engineers, SAE Std.

Because of the complex constructional details, the stress distribution at the joint between the main arch and spandrel arch is very complicated. To explore the mechanical behavior of this new type of arch bridge, particularly the stress state at the joint of the arch, a 1:5-scaled model of a segment for a sunflower arch bridge was tested. The displacements and stresses at key locations of the tested model were recorded. The experimental results showed that the displacements of the main arch and spandrel arch under dead loads were notably small, which indicated that the global stiffness of the arch was sufficiently large. Moreover, the maximum tensile stress at the end of the spandrel arch subjected to dead loads was larger than the tensile strength of the concrete; therefore, the concrete in these regions is vulnerable to cracking. To avoid cracks at the end of the spandrel arch, an optimized design scheme was proposed for the joint using a steel I-beam to replace the concrete at the end of the spandrel arch. Design parameters were also suggested through a comprehensive parametric investigation based on finite-element analysis (FEA). © 2018 American Society of Civil Engineers.","Finite-element analysis (FEA); Mechanical behavior; Model test; Optimal design; Sunflower arch bridge","Arches; Cracks; Finite element method; Optimal systems; Reinforced concrete; Tensile strength; Concrete arch bridges; Design parameters; Displacements and stress; Mechanical behavior; Model tests; Optimal design; Optimized designs; Parametric investigations; Arch bridges",,,,,"National Natural Science Foundation of China, NSFC: 51678169; China Scholarship Council, CSC: 201708440154; Pearl River S and T Nova Program of Guangzhou: 201605061406434; Science and Technology Planning Project of Guangdong Province: 2016B050501004","This research was financially supported by the National Natural Science Foundation of China (51678169), the Pearl River S&T Nova Program of Guangzhou (201605061406434), the Technology Planning Project of Guangdong Province (2016B050501004), and the Scholarship of the Chinese Scholarship Council (201708440154).

Recent adoption of flexible filler materials in post-tensioning tendons in bridge construction – an alternative to the more typical cementitious grout which is currently common in the U.S. – has implications on member flexural behavior. This paper describes the development and experimental validation of a simplified, computationally inexpensive finite element modeling (FEM) approach for unbonded tendons. Flexural members containing both unbonded post-tensioned steel and bonded pretensioned steel, or “mixed tendons” were modeled. FEM results were then validated against experimentally obtained ultimate strength, tendon stress, and plastic hinge length data. The developed analytical approach described herein was found to predict the ultimate flexural strength, failure mode and tendon stress with good accuracy, within 5%. Prediction of the ultimate displacement was fairly accurately modeled (within 15%) for the mixed tendon beams. © 2018 Elsevier Ltd","Bridge; Finite element method; Flexible filler; Mixed tendons; Non-linear analysis; Plastic hinge; Post-tensioning; Prestressing; Unbonded tendons","Bridges; Corrosion protection; Fillers; Finite element method; Prestressed concrete; Prestressing; Steel corrosion; Wire; Experimental validations; Plastic hinges; Post-tensioned bridges; Post-tensioned concrete; Post-tensioned steels; Posttensioning; Ultimate flexural strength; Unbonded tendons; Tendons; bridge; concrete structure; finite element method; nonlinearity; numerical model; structural component; United States",,,,,"Florida Department of Transportation, FDOT: BDV31-977-15","The authors would like to thank Schwager-Davis for their donation of materials utilized in the laboratory testing.

Further, very few studies are available on the fatigue performance of FRP-strengthened reinforced concrete beams in bridges. Investigation of the fatigue performance of FRP bonded to concrete is important due to the fact that bridges are subjected to very high levels of cyclic loading throughout their lifetime. This paper focuses on a numerical and experimental investigation of the fatigue life of FRP laminates bonded to concrete. FRP-to-concrete joints were subjected to cyclic loading at various stress ratios and the number of cycles prior to failure was used to generate S-N curves which relate the stress ratio to the number of cycles. Further, numerical simulations using the finite element method were performed using a concrete material model capable of sustaining fatigue damage. The finite element results were found to be in good agreement with the experimental data and were used to provide further insights into the mechanisms of fatigue damage. Both the experimental and numerical results showed that no fatigue degradation occurred when the maximum stress ratio was less than 75% of the ultimate static capacity. © 2018 Elsevier Ltd","CFRP laminate; Crack propagation; Fatigue life; Maximum stress; Strengthening","Concrete beams and girders; Crack propagation; Cyclic loads; Fatigue of materials; Finite element method; Numerical methods; Paper laminates; Reinforced concrete; Strengthening (metal); Stress analysis; CFRP laminate; Concrete material models; Experimental investigations; Fatigue degradation; Fatigue performance; Finite element investigation; Maximum stress; Reinforced concrete beams; Fatigue damage",,,,,"Swinburne University of Technology","This first author would like to acknowledge the technical support provided by the staff of the Smart Structures Laboratory at Swinburne University of Technology for the conduct of the experimental work.

Moreover, the amplification ratio of the designed bridge-type nano-positioner is obtained by taking the guiding mechanism as the external load of bridge-type mechanism. Comparing with existing methods, the proposed model is more accurate, which is further verified by finite element analysis(FEA) and experimental test. The consistency of the results obtained from theoretical model, FEA and experimental testing indicates that the proposed model can accurately predict the amplification characteristics of nano-positioners, which helps the analysis and design of bridge-type nano-positioners in practical applications. © 2019 Copernicus GmbH.

The costs of these specific treatments and further maintenance can be reduced by exploiting weathering steel, the so-called CORTEN steel. The rust of this material forms a protective layer, adherent and self-regenerative, capable to stop the oxidation of the raw material. This characteristic, called self-passivation, is achieved by adding Cu, Cr and P in the alloy. Furthermore, its natural rust-color inspired architects, artists and civil engineers that start using CORTEN for bridges, building facades, artworks etc.. The harmony of CORTEN with natural environments boosts its application for guardrails (safety barriers) along the highway and alpine roads of the South-Tyrolean region. These components, in addition to aesthetic characteristics, have to fulfill safety requirements, especially during crash events. During an impact, the main goal of guardrails is to absorb and dissipate energy. Large deformations take place. Therefore, the most important mechanical characteristic for guardrails' materials is the tenacity related to the ductile behavior. However, despite CORTEN guardrails are homologated through experimental tests, in some specific conditions the passivation process could fail. Therefore, its energy absorption capabilities can be jeopardized by corrosion. In order to verify and/or optimize specific guardrails' geometries for safety applications, it is important to be able to model the ductile behavior and fracture locus of CORTEN within finite elements. The goal of this paper is to characterize the ductile behavior of CORTEN through experimental quasi-static tests with different geometries, thus different level of triaxiality. The test configurations were numerically reproduced, to retrieve the actual stress state, quantify the plastic strain at failure and calibrate a ductile damage model. © 2019 The Authors.

The analytical parameters were the hole positions that increased the shear strengths of RC beams in static loading experiments, the crack positions, and the widths. As a result of the analyses, for beams with holes arranged from near the loading points toward the positions of tensile rebars at the mid-shear span with no stirrups, when the beams had a horizontal crack, the strengths increased to the flexural capacities. However, when the beam had vertical cracks, the strength decreased to 80% for beams without holes. Meanwhile, for beams with holes arranged from the bottom side of the loading points toward the mid-height with no stirrups, the strength increased to between 110% and 160% compared with beams without holes regardless of the crack positions. Moreover, the shear behaviors of the beams did not change when the equivalent crack width exceeded 0.3 mm for each case, and changes in the behaviors of beams with stirrups were negligibly small regardless of the hole positions. It was made clear that changes in the behaviors were caused by the contributions of arch mechanisms enhanced by localizations and expansions of the minimum principal stress distributions owing to the multiple holes. © 2019 Japan Concrete Institute.",,"Arch bridges; Concrete beams and girders; Reinforced concrete; Shear flow; Analytical parameters; Analytical studies; Artificial cracks; Equivalent crack; Flexural capacity; Horizontal cracks; Non-linear finite-element analysis; Reinforced concrete beams; Loading",,,,,,,,,,,,,,,,"Aoyagi, Y., Yamada, K., Strength and deformation characteristics of reinforced concrete shell elements subjected to in-plane forces (1983) Proc.

In particular, a numerical model is implemented to evaluate initial configuration under dead loads and nonlinearities due to nonlinear geometric effects in bridge components arising from instability phenomena. The main aim of the paper is to identify the most relevant bridge components, which are affected out-of-plane instability behavior of the structure. The nonlinear behavior of tied arch bridges is evaluated by means of a three-dimensional finite element model, in which several wind bracing system layouts and cable system configurations are considered. A comparative analysis between Elastic Buckling Analysis and Nonlinear Elastic Analysis methodologies is developed to achieve a more accurate evaluation of the maximum capacity of the structure against instability phenomena. Comparisons in terms of buckling assessment between numerical evaluations and simplified methodologies reported in current codes on bridge structures are proposed. Results show that the simplified methodologies overestimate the instability capacity in most of the bridge configurations, which have been dimensioned according to the preliminary design rules commonly adopted in current applications. © 2019 The Authors.

In the proposed model, concrete is parted into four important phases: aggregates, cement matrix, interfacial transition zone (ITZ), and the initial defects. Aggregate particles were modelled as randomly distributed polygons with a varying size according to the sieve curve developed by Fuller and Thompson. With regard to initial defects, only voids are considered. Cohesive elements with zero thickness are inserted into the initial mesh of cement matrix and along the interface between aggregate and cement matrix to simulate the cracking process of concrete. The constitutive model provided by ABAQUS is modified based on Wang's experiment and used to describe the failure behaviour of cohesive elements. User defined programs for aggregate delivery, cohesive element insertion and modified facture constitutive model are developed based on Python language, and embedded into the commercial FEM package ABAQUS. The effectiveness and accuracy of the proposed model are firstly identified by comparing the numerical results with the experimental ones, and then it is used to investigate the effect of meso-structure on the macro behavior of concrete. The shear strength of concrete under different pressures is also involved in this study, which could provide a reference for the macroscopic simulation of concrete component under shear force.

During field loading, maximum moments of between 74% and 87% of the moment caused by AASHTO HL-93 loading with impact were applied to the structures. Strain readings indicated partial to full unintended composite action and significant restraint at the girder ends for all structures. HL-93 operating load ratings were modified using the strain measurements recorded during diagnostic load tests, leading to an average increase in moment rating factor of 52%. A novel approach of calibrating 3D FE models was developed that captures the observed full and partial composite action observed during testing, as well as restraint of the girder ends, giving good agreement between model-predicted and measured strains. The FE models were used to directly predict bridge capacities and rating factors while explicitly capturing girder yielding and load redistribution. The effects of unintended composite action, end restraint and concrete deck stiffness on capacity were examined using these models. The most conservative FE-estimated rating factors that ignored unintended composite action and end restraint - which are likely unreliable at large loads - were 54% higher than the conventional, code-based rating factors. © 2019 - IOS Press and the authors.

The ultimate capacity of such sections, which needs to be exactly predicted, is crucial to the safety of the whole bridge. A narrow type steel box section (NTSBS) with width to height ratio of 4.18 is deployed in Egongyan Rail Special Bridge, which is a railway self-anchored suspension bridge with 1120 m span in total. In order to comprehensively investigate the ultimate capacity of NTSBS, the behavior of NTSBS under the most unfavorable internal forces is herein studied by means of experiments and numerical simulations. Firstly, a representative steel box girder is selected to be an experimental rescale model and the most unfavorable internal forces are determined by computation analysis. Then, a load test is conducted on the rescale model of NTSBS girder. The experimental method is introduced, including the loading method and layout of measuring points. During this loading procedure, the prestress loss of the steel strands in the self-loading system is considered in order to improve the accuracy of the actual eccentric loading. Subsequently, a finite element (FE) model meshed by shell element is validated using the test results and is used to investigate effects of residual stress and geometric imperfections. Finally, the FE method is extrapolated to the full scale model, the actual ultimate capacity is obtained, and effect of geometric imperfections of mid webs and failure mechanism are investigated. © 2019 by The Hong Kong Institute of Steel Construction.

However, currently, there is a lack of studies on the mode I fracture under dynamic loads. The present programme consisted of two sets of experiments to bridge this gap and to obtain the principal interfacial properties of such fracture. Direct tension tests and notched three-point bending tests were used to determine tensile bond strength and fracture energy of the FRP-concrete interface bond, respectively. Digital image correlation (DIC) measurements were used to characterise the fracture process. It was found that the two bond properties were close to those of plain concrete in the quasi-static regime and showed significant dynamic enhancing effect at a loading rate of 20 mm/s. Dynamic increase factor (DIF) equations for the two bond properties were provided to predict the interfacial response of FRP-concrete bond under dynamic loads.

This paper presents a highly detailed numerical model of an actual bridge subjected to extreme seismic action which results in its collapse. Normally, nonlinear numerical models have high difficulties to achieve convergence when reinforced concrete is intended to be represented. The main objective of this work is to determine the efficiency of different passive control strategies to prevent the structural collapse of an existing bridge. Metallic dampers and seismic isolation by decoupling the mass were evaluated. The response is evaluated not only in terms of reduction of displacements, but also in increasing of shear force and axial force in key elements, which can be a negative characteristic of the systems studied. It can be concluded that the use of a metallic damper significantly reduces the horizontal displacements and ensures the integrity of the structure from extreme seismic actions. Moreover, the isolation of the deck, which in principle seems to be the most effective solution to protect existing bridges, proves inadequate for the case analysed due to its dynamic characteristics and its particular geometry and an unpredictable type of axial pounding in the columns. This unexpected effect on the isolation system would have been impossible to identify with simplified models.

Aeroelastic phenomena, good candidates to yield high energy performance in renewable wind energy harvesting (EH) systems, can play a pivotal role in providing sufficient power for extended operation with little or no battery replacement. In this paper, a numerical model and a co-simulation approach have been developed to study a new EH device for power generation. We investigate the problem focusing on a weakly aerodynamically coupled flutter-based EH system. It consists of two flexible wings anchored by cantilevered beams with attached piezoelectric layers, undergoing nonlinear coupled bending–torsion limit cycle oscillations. Besides the development of individual EH devices, further issues are posed when considering multiple objects for realizing a network of devices and magnifying the extracted power due to nonlinear synergies and constructive interferences. This work investigates the effect of various external conditions and physical parameters on the performance of the piezoaeroelastic array of devices. From the viewpoint of applications, we are most concerned about whether an EH can generate sufficient power under a variable excitation. The results of this study can be used for the design and integration of low-energy wind generation technologies into buildings, bridges, and built-in sensor networks in aircraft structures. © 2020 by the authors.

However, these methods struggle with rust removal in narrow areas, causing environmental problems such as dust scattering, and noise. In order to solve these problems, surface preparation, using a laser, has been researched and developed. In this study, we investigated the applicability of the clean laser system to the surface preparation of steel, experimentally, and analytically. The coating and rust removal experiments, using the clean laser system were performed with two types of specimens, both employing different coating systems. Furthermore, the coating thickness, surface observation using a microscope, and adhesion test were investigated during the tests. Subsequently, the thermal finite element analysis was performed under the same conditions as that of the experiments. It was revealed that the optimal condition for coating and rust removal was determined by the laser power, pulse width, scan width, and scan speed. © 2020, Korean Society of Steel Construction.","Clean laser; Coating; Repainting; Rust; Surface preparation","Thickness measurement; Applicability evaluation; Blasting method; Coating thickness; Environmental problems; Optimal conditions; Surface observation; Surface preparation; Thermal finite element analysis; Coatings",,,,,"18CTP-C143604-01","This research was carried out from the research support of the Ministry of Land, Infrastructure and Transport Construction Technology Research Project (18CTP-C143604-01).",,,,,,,,,,"(2016) ABAQUS theory manual, Ver. 6.12, , DSS, Providence; (1995), Eurocode 3: Design of steel structures, part 1.2: General rule -structural fire design (ENV 1993-1-2: 1995), Belgium; Hwang, H.T., Choi, H.W., Kim, J.D., A study on laser surface treatment characteristics of high carbon steel (HP4MA) for injection mold (2011) Korean Society of Manufacturing Technology, KSMTE, 20 (5), pp. 646-652. , (in Korean; Jujii, K., Kitane, Y., Nakano, T., Applicability of laser cleaning for surface preparation of steel (2018) Bridge and Foundation Engineering, Kensetutosyo, 52 (10), pp. 31-34. , (in Japanese; Kim, H.S., Shin, C.H., Dao, D.K., Jeong, Y.S., Kim, I.T., Evaluation on residual compressive strength of welded circular tubular members with locally corroded ends (2018) Journal of Korean Society of Steel Construction, KSSC, 30 (3), pp. 145-152. , (in Korean; Lee, C.Y., Jung, M., Park, J.W., Lee, I.Y., Jang, S.D., Case study on maintenance coatings for steel arch bridge considering corrosion environment of bridge members (2015) Magazine of the Korean Society of Steel Construction, KSSC, 27 (2), pp. 29-33. , (in Korean; (2003) Maintenance Manual for Corrosion Prevention of Steel Bridges, pp. 87-89. , MOCT, Sejong: (in Korean; Mo, Y.W., Yoo, Y.T., Shin, B.H., Shin, H.J., Welding characteristics on heat input changing of laser dissimilar metals welding (2006) Journal of Transactions of the Korean Society of Machine Tool Engineers, KSMTE, 15 (2), pp. 51-58. , (in Korean; Mun, J.M., Jeong, Y.S., Jeon, J.H., Ahn, J.H., Kim, I.T., Experimentally evaluating fatigue behavior of corroded steels exposed in atmospheric environments (2017) Journal of Korean Society of Steel Construction, KSSC, 29 (3), pp. 193-204. , (in Korean; Park, J.E., Kyung, K.S., Moon, M.G., Koh, K.H., Hong, Y.J., Experimental study on application of clean laser system in surface preparation on steel (2019) Journal of Korean Society of Steel Construction, KSSC, 31 (6), pp. 447-458. , (in Korean","Kyung, K.-S.; Department of Civil Engineering, Taejong-ro, Yeongdo-gu, South Korea; email: kyungks@kmou.ac.kr",,,"Korean Society of Steel Construction",,,,,15982351,,,,"English","Int.

The diversity between design and actual DFs may be varied as the bridge parameters changed. To study this diversity, this paper presents an evaluation of lateral load DFs for prefabricated hollow slab bridges. The response of the bridge was recorded during the field test. This field test was divided into two stages: a concentrated force loading test on the prefabricated girder that settled on the bridge supports before the girders were connected transversely and a vehicle loading test after the girders were connected transversely. The instruments used to record the response of the bridge were strain gauges and dial indicators. The measured data in the multi-stages of the field test could be used to calibrate the support condition of the bridge and transverse connection between adjacent girders in the finite element model (FEM) using beam and plate elements. From the FEM, DFs for this hollow slab bridge were determined and compared with the DFs in the AASHTO LRFD specification. A parametric study using the calibrated FEM was then used to investigate the effect of various parameters including span length, skew and bridge deck thickness on the DFs. It was found that AASHTO LRFD specification is conservative compared with the analysis in the FEM, while this conservatism decreased as the span length and skew of the hollow slab bridge increased. © 2020, The Author(s).","distribution factor; field test in multi-stage; hollow slab bridge; support condition; transverse connection","Beams and girders; Loads (forces); Specifications; Testing; Bridge supports; Concentrated force loading; Distribution factor; Hollow slab bridges; Lateral load distributions; Parametric study; Support conditions; Vehicle loading; Bridges",,,,,"National Natural Science Foundation of China, NSFC: 51678061, 51978063","Finical support by the key research platform open fund project of China No. 310821171121.

Its main span of 1074 m was originally designed to be suspended by inclined hangers; in 2015, the original inclined hangers were replaced by vertical ones. In-situ ambient vibration measurements were taken at different stages of this operation to gain an understanding of the effects of the hanger cable orientation on the overall dynamic behaviour of the bridge. Measurements were also recorded for various periods spanning several weeks to observe operational variations on the modal frequencies of vibration. Measurements were made on the tower, the deck and the hangers. It was observed that, as a result of the hanger replacement, frequencies of the modes involving predominant deck motion decreased on the order of 6 to 16% while the frequencies of the modes involving predominant tower motion showed almost no change. A finite element model of the Bridge was also developed to further investigate the physical reasons behind the observed changes in modal frequencies and similar trends were observed in the modal frequencies yielded by the finite element models developed for the inclined and the vertical hanger configurations. © 2020 Informa UK Limited, trading as Taylor & Francis Group.","Ambient vibration survey; Bosporus suspension bridge; finite element model; hanger replacement; long-term monitoring; modal identification","Cable stayed bridges; Finite element method; Suspension bridges; Ambient vibrations; Bosporus; hanger replacement; Long term monitoring; Modal identification; Electric measuring bridges",,,,,"15A04S3","The financial support of Bogazici University under the grant number of 15A04S3 is highly acknowledged.

The method can be used to analyze large-scale VTB systems accurately and efficiently. Based on the principle of virtual work, the equations of motion are derived for two separate subsystems, i.e. a small-scale of finely modeled VTB substructure and a coarsely meshed large main bridge subsystem using different level of refinement. Different from the conventional dynamic substructuring approaches, the bridge spans close to the vehicle are modeled in both the main and substructure models, and the contradiction of repeatedly modeling is solved using a ""nonlinear force corrector"". A special wheel-rail interaction (WRI) element is used to simulate the fast-moving interaction force between the vehicle and rail. In this way, the two models remain unchanged while the vehicle moves forward, and the computational accuracy is the same as the large-scale purely refined model, while the efficiency is significantly improved, particularly, for the large-scale long VTB systems. Two examples of realistic VTB systems with either smooth or un-smooth rails are used to verify the proposed method. The results demonstrate that the presented method has remarkable advantages of computational efficiency and accuracy, providing a practically useful tool for analysis of large-scale VTB systems. © 2020 World Scientific Publishing Company.","client-server; finite element method; OpenSees; substructure method; Vehicle-track-bridge system; wheel-rail interaction","Computational efficiency; Efficiency; Equations of motion; Numerical methods; Vehicles; Bridge systems; Computational accuracy; Dynamic substructuring; Interaction forces; Nonlinear force; Principle of virtual work; Refined model; Substructure method; Large scale systems",,,,,"National Science Foundation, NSF: 51261120376, 51578473, 51978591; National Key Research and Development Program of China, NKRDPC: 2016YFC0701106","The authors acknowledge Mr. Weiquan Li for his contribution to building the numerical models.

The interface was modeled with a proper nonlinear cohesive law which couples mode I (tension-crack) with mode II (shear-slip) behaviors. The input parameters of the FE simulation were provided by a new bond test which reproduces a realistic condition of cracking/debonding pattern. The FE simulations were accomplished by varying the overlay materials and the moisture levels of the substrate surface prior to overlay, since findings about their influence on the bond performances are still controversial. The proposed FE model proved to effectively predict the bond failure of composite NSC-HPFRC/UHPFRC members. © 2020 Elsevier Ltd","Bond tests; Composite structures; Contact problem; Debonding damage; Numerical modeling; Peeling stress; Shear stress; UHPFRC layer","Fiber reinforced concrete; High performance concrete; Cohesive finite element; Concrete elements; Input parameter; Nonlinear cohesive law; Normal strength concretes; Realistic conditions; Substrate surface; Ultra-high-performance fiber-reinforced concrete; Finite element method",,,,,"Ministero dell’Istruzione, dell’Università e della Ricerca, MIUR: 2017HFPKZY","Authors gratefully acknowledge the financial support provided by HEIG–VD (Haute Ecole d'ingénieurs et de gestion du canton de Vaud – Switzerland).

Among them, hollow-type sections are of more consideration in Japan that exhibit good performance in practice. The transfer of large stresses from strands to concrete causes these sections to undergo horizontal cracking at the ends of the girders. To avoid such problem, this paper presents the implementation of various methods to the ends of two specimens prepared physically. Horizontal end cracks could not be fully eliminated by either of the methods in the selected type girder, but the method of enhancing end-zone reinforcement alongside strand-debonding could considerably decrease the principal stress that resulted in minimizing the cracks to a negligible level. To validate the experimental program, numerical models of the girder with identical parameters were simulated using the Finite Element Analysis software. Results obtained numerically well-matched the experimental ones to the extent of showing even the cracks pattern and vicinity. © 2020, Springer Nature Switzerland AG.","Hollow pretensioned girders; Horizontal cracks; MIDAS FEA; Prestressed concrete","Prestressed concrete; Bridge design; Cracks patterns; Experimental and numerical studies; Experimental program; Finite element analysis software; Horizontal cracking; Pretensioned; Principal stress; Concrete beams and girders",,,,,,,,,,,,,,,,"Oliva, M.G., Pinar, O., (2011) Finite Element Analysis of Deep Wide-Flanged Pre-Stressed Girders to Understand and Control End Cracking, , Wisconsin Highway Research Program; Okumus, P., (2012) Nonlinear Analysis of Pretensioned Bridge Girder Ends to Understand and Control Cracking at Prestress Release, , Doctoral dissertation, The University of Wisconsin-Madison; Steensels, R., Vandewalle, L., Vandoren, B., Degée, H., A two-stage modelling approach for the analysis of the stress distribution in anchorage zones of pre-tensioned, concrete elements (2017) Eng Struct, 143, pp. 384-397; Ebrahimkhanlou, A., Athanasiou, A., Hrynyk, T.D., Bayrak, O., Salamone, S., Fractal and multifractal analysis of crack patterns in prestressed concrete girders (2019) J Bridge Eng, 24 (7), p. 04019059; Tadros, M.K., Badie, S.S., Tuan, C.Y., (2010) Evaluation and Repair Procedures for Precast/Prestressed Concrete Girders with Longitudinal Cracking in the Web, 654. , Transportation Research Board; Shaw, I., Andrawes, B., Repair of damaged end regions of PC beams using externally bonded FRP shear reinforcement (2017) Constr Build Mater, 148, pp. 184-194; Yapar, O., Basu, P.K., Nordendale, N., Accurate finite element modeling of pretensioned prestressed concrete beams (2015) Eng Struct, 101, pp. 163-178; Okumus, P., Oliva, M.G., Strand debonding for pretensioned bridge girders to control end cracks (2014) ACI Struct J, 111 (1), p. 201; Karimi, A.K., Jaheed, A.B., Aasim, B.A., Farooqi, J.A., Structural condition and deficiencies of present constructed bridges over Zahirshahi Canal and proposal of new design using AASHTO codes (2019) World J Eng Technol, 7 (2), pp. 325-332; Bruce, S.M., McCarten, P.S., Freitag, S.A., Hasson, L.M., Deterioration of prestressed concrete bridge beams.

The proposed structure is an improvement over single-bridge micromirrors in terms of aperture size, pull-in voltage, degrees of freedom, and fill factor. The two-axis symmetric rotation mechanism of the proposed micromirror is achieved by bending and twisting action of the suspended cantilevers which is contrary to the twisting cantilevers of a conventional one-axis torsional micromirror. The placement of anchor and cantilevers under the mirror plate results in a high fill factor when arranged in a 2-D array. The analytical modeling, design optimization, and static and dynamic analysis are done using finite-element method (FEM) in Coventorware. An optimized design is fabricated using a simple approach of surface micromachining and electroplating. For a micromirror of size $200\,\,\mu \text{m}\,\,\times 200\,\,\mu \text{m}$ and the actuation gap of $2.5~\mu \text{m}$ , the device exhibits a tilt angle of 1.5° at a pull-in voltage of 23.1 V, a switching time of $38~\mu \text{s}$ , and the resonance frequency of 35.23 kHz. A ${3} \times {3}$ array of the micromirror is demonstrated with a fill factor of more than 95%. The deflection range can be increased by simply increasing the thickness of the sacrificial layer and without any major process modification. © 1963-2012 IEEE.","Double-bridge micromirror; gold electroplating; multiobject spectroscopy (MOS); surface micromachining","Degrees of freedom (mechanics); Electrostatic actuators; Nanocantilevers; Surface micromachining; Design and Development; Design optimization; Multiobject spectroscopy; Process modifications; Resonance frequencies; Rotation mechanism; Static and dynamic analysis; Torsional micromirrors; Bridges",,,,,"Council of Scientific and Industrial Research, India, CSIR; Bangladesh Council of Scientific and Industrial Research, BCSIR","Manuscript received July 20, 2020; accepted August 11, 2020.

In particular, deck slabs of existing bridges often show significant deficits in design shear capacity, although no damage has been reported so far. A test series of 14 large-scale cantilever slabs subjected to concentrated loads was conducted and analysed at the Hamburg University of Technology. Varying the distance between the concentrated load and the support in a previously unexamined wide range led to new considerations regarding the shear capacity in RC slabs. The ultimate and residual loads of the test specimens, as in many other studies on this topic, clearly exceeded the values for vehicle load assumptions in the current standards. In contrast to previous studies, a large shear slenderness in the load arrangement could be realized in the tests. This was the basic requirement for one of the key findings: The critical shear crack occurs locally in the area of load application and not at the support. Thus, shifting the design section for shear close to the concentrated load is reasonable, while in many approaches a critical section close to the support is chosen. Furthermore, the often-used effective width beff, which depends on the distance of single loads to the support, does not seem justified. The shear forces should be determined by finite element analysis, a common method in practice, which can consider the spatial load transfer and the stiffness of the support in a realistic manner. The new design method presented here is therefore not primarily concerned with the shear resistance, as other investigations are, but first on the side of determining the relevant internal shear forces, which are initially higher in the design section proposed here. Only in a second step is a preliminary factor C*Rd,c for the calculated resistance determined by means of a well-founded statistical evaluation. For this purpose, a database with 45 tests on RC slabs has been established. The new design approach provides significant greater shear capacities than the current regulations. © 2020 Elsevier Ltd","Concentrated load; Concrete bridge; Design assisted by testing; Shear; Slab; Wheel load","Bridges; Concentration (process); Concrete construction; Concrete slabs; Concrete testing; Design; Loads (forces); Petroleum reservoir evaluation; Shear flow; Shear strength; Testing; Concentrated load; Critical sections; Current regulations; Design approaches; International researches; Shear reinforcement; Shear resistances; Statistical evaluation; Reinforced concrete; building code; design; floor; loading test; reinforced concrete; shear strength; stiffness; structural analysis; structural response",,,,,"Bundesanstalt für Straßenwesen, BASt; Deutsche Forschungsgemeinschaft, DFG: RO 793/13-1","At present, a similar approach for practical application in concrete bridge design is being developed as part of a research project funded by the German Federal Highway Research Institute (BASt).","The authors acknowledge the German Research Foundation (DFG) for the financial support of the project (project no.

The paper comprises measurements of the global response of the bridge to prepare a verified and validated FEM (Finite Element Method) model. A complex measuring system used for the tests consisted of two main parts: an interferometric IBIS-S (Image by Interferometric Survey-Structures) radar and a multichannel vibration and strain data logger. Next, structure-vehicle interactions were modelled, and non-linear numerical dynamic analyses were performed. As a result, the time histories of displacements of the structure from traffic effects were obtained. Their comparison with IBIS-S radar records proves that this method can be effectively used for assessing bridges subjected to common traffic loads. The results (measured accelerations) obtained by local tests in external pre-stressed cables are presented and a convenient method for acquiring the axial force in the cables is proposed. © 2020 by the authors.","Accelerations; Displacements; FEM model; In situ measurements; Non-linear dynamic analysis; Reinforced concrete bridge; Strains",,,,,,"Ministerstvo školstva, vedy, výskumu a športu Slovenskej republiky: 1/0749/19","Funding: This paper was supported by the Grant Agency of the Ministry of Education, Science, Research and Sports of the Slovak Republic VEGA No. 1/0749/19.",,,,,,,,,,"Strauss, A., Frangopol, D.M., Kim, S., Use of monitoring extreme data for the performance prediction of structures: Bayesian updating (2008) Eng.

Laying rail expansion regulators is an effective measure to reduce the additional force. The nonlinear finite element model is presented for a continuously welded rail track with a rail expansion regulator resting on the embankment and simple and continuous beams, considering the temperature change of the bridge. Then, a method is proposed to determine the locations of the rail expansion regulator and the fixed bearing of the continuous beam, corresponding to the maximum additional forces of rail reaching minimum values. Their appropriate matching locations are recommended based on the obtained influence laws of any locations of the rail expansion regulator and the fixed bearing of the continuous beam on the maximum additional forces of rail. The results can provide the theoretical basis for the design of the rail expansion regulator and the fixed bearing of long-span continuous bridges. © 2020 by the authors.","Continuous beam; Continuously welded rail; Finite element method; Nonlinear stiffness; Rail expansion regulator; Rail-bridge thermal interaction",,,,,,"P2018G047; National Natural Science Foundation of China, NNSFC: 51578552, U1334203","Acknowledgments: This research was supported by the National Natural Science Foundation of China (Nos. 51578552, U1334203) and China Railway Corporation Science and Technology Research and Development Project (P2018G047).",,,,,,,,,,"Frỳba, L., (1996) Dynamics of Railway Bridges, , Thomas Telford Ltd.: London, UK; Esveld, L.C., (2001) Modern Railway Track, , MRT Production: Kâgithane/Istanbul, Turkey; Cutillas, A.M., Track-Bridge Interaction Problems in Bridge Design (2009), pp. 19-28. , Taylor & Francis: Oxford, UK; Freystein, H., Track/bridge-interaction-State of the art and examples (2010) Stahlbau, 79, pp. 220-231; Chen, R., Wang, P., Wei, X.K., Track-bridge longitudinal interaction of continuous welded rails on arch bridge (2013) Math.

For this purpose, the present study investigates the effects of TGMs on the inelastic seismic response of continuous concrete box-girder highway bridges with seat type abutments. Three-dimensional finite element (3D FE) models of bridges with varying skew angles, number of bent columns, and column height-to-diameter ratios were developed using OpenSees, and a series of nonlinear response history analyses were conducted. Comparison of seismic response of bridges subjected to only translational and both translational and TGMs revealed that TGMs may result in uneven and asymmetric failure of the shear keys. Therefore, deck rotations are significantly amplified due to induced instantaneous eccentricity when deck comes in contact with shear key(s). The amplified impact forces due to TGMs further amplify the deck rotations, which in return result in higher inelastic displacement and force demand. Last but not the least, the induced torsion due to TGM combined with axial-flexure-shear interactions may result in complex failure modes, higher shear stresses, and reduction in lateral deformation and flexural capacity of the bridge columns. © 2020 Elsevier Ltd","Continuous box-girder bridge; Rotational ground motion; Seat-type abutment; Shear key; Skew bridge; Torsion","Box girder bridges; Concrete beams and girders; Seismic response; Shear stress; Steel bridges; Complex dynamic characteristics; Concrete box girders; Inelastic displacement; Inelastic seismic response; Nonlinear response history analysis; Strong ground motion; Three-dimensional finite element (3D FE); Torsional components; Highway bridges; bridge; dynamic response; finite element method; ground motion; numerical model; seismic response; structural response; torsion",,,,,,,,,,,,,,,,"Buckle, I.G., (1994), The Northridge, California earthquake of January 17, 1994: performance of highway bridges.

The precast bridge column adopting the connections was testified to be on a par with the monolithic concrete counterpart in terms of seismic performance in previous research. This paper aims to develop a numerical model to further investigate the seismic behavior of the proposed bridge column considering the bar-slip effect. A finite element model was established for the bridge columns considering deformation components of flexure, shear, and bar-slip. The bond behavior between the deformed bar and UHPC was defined using a new practical model, which was developed based on a pullout test including five specimens in this research. The established finite element model was verified by the cyclic loading test in literature in terms of the overall hysteretic curve and local responses. The validated model was used to conduct parametric analysis to study the contributions of the different deformation components to lateral deformation as well as the effects of large-diameter bars on seismic performance. Results show that all the pullout specimens have the tensile fracture of bars, which indicates that the development length of 5 times bar diameter is sufficient for deformed bars in UHPC when the bar diameter is no more than 32 mm. The practical model is effective to consider the effects of the slip between the deformed bar and UHPC. The finite element model can predict the overall hysteretic curve and local responses at different drift ratios. The bar-slip has a considerable even dominative contribution to the lateral deformation of the proposed bridge column. Larger bar diameter can enhance deformation capacity as well as reduce energy dissipation and residual drift ratio. © 2020, Springer Nature B.V.","Bar-slip effect; Bridge columns; Lap splice; Large-diameter bars; Precast construction; Seismic behavior; Ultra-high performance concrete","Cyclic loads; Deformation; Energy dissipation; Grouting; Hysteresis; Mortar; Seismic response; Seismic waves; Ultra-high performance concrete; Cyclic loading test; Deformation capacity; Deformation component; Lateral deformation; Monolithic concrete; Parametric -analysis; Seismic Performance; Ultra high performance concretes (UHPC); Finite element method; bridge construction; connectivity; energy dissipation; finite element method; grout; numerical method; parameterization; porous medium; seismic response; slip rate",,,,,"2017G006-C; KYY2019096; National Natural Science Foundation of China, NSFC: 51438003","The work described in this paper was financially supported by the National Natural Science Foundation of China (Grant No. 51438003), the Project of Science and Technology Research and Development Plan of China Railway Corporation (Grant No. 2017G006-C), and the Science and Technology Research Plan of China Railway Eryuan Engineering Group Corporation (KYY2019096(19-21)).",,,,,,,,,,"Ameli, M.J., Pantelides, C.P., Seismic analysis of precast concrete bridge columns connected with grouted splice sleeve connectors (2016) J Struct Eng ASCE, 143 (2), p. 04016176; Ameli, M.J., Parks, J.E., Brown, D.N., Pantelides, C.P., Seismic evaluation of grouted splice sleeve connections for reinforced precast concrete column-to-cap beam joints in accelerated bridge construction (2015) PCI J, 60 (2), pp. 80-103; Ameli, M.J., Brown, D.N., Parks, J.E., Pantelides, C.P., Seismic column-to-footing connections using grouted splice sleeves (2016) ACI Struct J, 113 (5), pp. 1021-1030; Bae, S., Bayrak, O., Plastic hinge length of reinforced concrete columns (2008) ACI Struct J, 105 (3), pp. 290-300; Billington, S.L., Yoon, J.K., Cyclic response of unbonded posttensioned precast columns with ductile fiber-reinforced concrete (2004) J Bridge Eng ASCE, 9 (4), pp. 353-363; Billington, S.L., Barnes, R.W., Breen, J.E., Alternate substructure systems for standard highway bridges (2001) J Bridge Eng ASCE, 6 (2), pp. 87-94; Binard, J.P., UHPC: a game-changing material for PCI bridge producers (2017) PCI J, 62 (2), pp. 34-46; Cheng, Z., Sritharan, S., Side shear strength of preformed socket connections suitable for vertical precast members (2019) J Bridge Eng ASCE, 24 (5), p. 04019025; Cheng, H., Li, H., Wang, D., Sun, Z., Li, G., Jin, J., Research on the influencing factors for residual displacements of RC bridge columns subjected to earthquake loading (2016) Bull Earthq Eng, 14 (8), pp. 2229-2257; Chopra, A.K., (2012) Dynamics of structures: theory and applications to earthquake engineering, , 4, Prentice-Hall, Upper Saddle River; Culmo, M.P., Connection details for prefabricated bridge elements and systems (2009) Report No. FHWA-IF-09-010.

However, several old CFST arch bridges in China use ordinary concrete, whose fluidity before initial setting produces cap gaps at the top of the transverse brace. Furthermore, harsh environments and concrete dry shrinkage enlarge the gaps, producing composite defects. Hence, using ultrasonic scanning, this study performs a scale-model experiment and finite-element analysis to determine the bearing capacity of a serviced CFST arch bridge transverse brace with cap gap and air void defects in the concrete core column under small eccentric axial compression. Parametric analyses were conducted to investigate the influence of the composite defects on the bearing capacity of the transverse brace. A new ultimate strength index of the brace with composite defects was proposed, including a simplified formula for estimating the effects of cap gap and air void defects on the ultimate strength of the CFST arch bridge transverse brace. Thus, this study can provide a strong foundation for the construction of reliable CFST arch bridges. © 2020 American Society of Civil Engineers.","Air void; Arch bridge; Cap gap; Concrete-filled steel tube; Finite element method","Arch bridges; Arches; Bearing capacity; Composite structures; Defects; Self compacting concrete; Shrinkage; Concrete core columns; Concrete-filled steel tube arch bridge; Concrete-filled steel tubes; Eccentric axial compression; Parametric -analysis; Scale model experiment; Simplified formula; Ultrasonic scanning; Tubular steel structures",,,,,"XLYC1907121; lnjc201904; Natural Science Foundation of Liaoning Province: 20180550442; National Key Research and Development Program of China, NKRDPC: 2018YFD1100404","This research was supported by the National Key Research and Development Program of China (No. 2018YFD1100404); Plan of Liaoning Province to revitalize Liaoning talents (No. XLYC1907121); Province Natural Science Foundation of Liaoning, China (No. 20180550442); and Scientific Research Project of Liaoning Provincial Department of Education (No. lnjc201904).",,,,,,,,,,"(2011) Building Code Requirements for Structural Concrete and Commentary, , ACI (American Concrete Institute).

Deterministic comparison of measurement results to the theoretical, FEM (finite element method)-based outcomes with possible further calibration is mostly applied. Sometimes, the data collected in the tests are also used to calibrate the reliability factors of bridge structures or their components. This work proposes to complement the stage of the load test design with the use of probabilistic tools. This approach is intended to provide a reliable and trustworthy limit range of measured values (e.g. displacements) instead of restrictive single values, streamlining the performance of in-situ tests. The proposed procedure is supported by an arch bridge example with the following uncertainty sources: random imperfections of the arch girder, random stiffness of the deck and random total weight of the applied load trucks. The presented calculations refer to global structural stiffness assessment. Both point estimate method (PEM) and response surface method (RSM) are applied here. It has been shown that the proposed procedure effectively supplements the deterministic approach, thus the suggested extension of application of probabilistic tools to bridge load test design is innovative and justified. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.","arch bridges; finite element method; Load tests; point estimate method; probabilistic methods; random variables; response surface method; structural response; uncertainty principles","Arch bridges; Arches; Load testing; Random variables; Stiffness; Surface properties; Testing; Uncertainty analysis; Point estimate method; Probabilistic methods; Response surface method; Structural response; Uncertainty principles; Finite element method",,,,,,,,,,,,,,,,"(2016) Manual for bridge evaluation, interim revisions, , 2nd ed., Washington, DC: American Association of State Highway and Transportation Officials,.

Based on their severity, these damages can compromise the integrity of the structure. External prestressing is often used as an effective strengthening or repair technique for vulnerable or damaged structures, respectively. However, applying external prestressing in local regions of the structure with limited space can be problematic and not feasible for conventional prestressing techniques. This study investigates an innovative method for applying external prestressing in local regions of bridge girders using externally mounted precast prestressing plate reinforced with shape memory alloy wires. A thin mortar plate with embedded curved shape memory alloy wire was experimentally tested to validate the proposed prestressing concept. Afterward, finite element analysis was performed on a concrete bridge girder to numerically investigate the performance of shape memory alloy precast prestressing plate in enhancing the shear and flexural behavior of the girder. Experimental and numerical results evidently demonstrated the feasibility and effectiveness of the innovative method in strengthening and repairing concrete structures through external local prestressing. © The Author(s) 2020.","concrete bridge girder; External prestressing; finite element analysis; repair; shape memory alloy; strengthening","Concrete beams and girders; Concrete bridges; Concrete buildings; Concrete construction; Disasters; Highway bridges; Numerical methods; Plate girder bridges; Plates (structural components); Prestressing; Shape-memory alloy; Concrete bridge girders; Damaged structures; Environmental conditions; External prestressing; Flexural behavior; Innovative method; Numerical results; Shape memory alloy wire; Repair",,,,,,,,,,,,,,,,"Abdulridha, A., Palermo, D., Behaviour and modelling of hybrid SMA-steel reinforced concrete slender shear wall (2017) Engineering Structures, 147, pp. 77-89; Andrawes, B., Shaw, I., Zhao, H., (2018) Repair & strengthening of distressed/damaged ends of prestressed beams with FRP composites, , University of Illinois at Urbana-Champaign, Champaign, IL, February, Report; Barros, J.A.O., Dias, S.J.E., Near surface mounted CFRP laminates for shear strengthening of concrete beams (2006) Cement and Concrete Composites, 28 (3), pp. 276-292; Bilotta, A., Ceroni, F., Nigro, E., Efficiency of CFRP NSM strips and EBR plates for flexural strengthening of RC beams and loading pattern influence (2015) Composite Structures, 124, pp. 163-175; Bonacci, J., Maalej, M., Behavioral trends of RC beams strengthened with externally bonded FRP (2001) ASCE Journal of Composites for Construction, 5 (2), pp. 102-113; Chahrour, A., Soudki, K., Flexural response of reinforced concrete beams strengthened with end-anchored partially bonded carbon fiber-reinforced polymer strips (2005) ASCE Journal of Composites for Construction, 9 (2), pp. 170-177; Chen, G.M., Zhang, Z., Li, Y.L., T-section RC beams shear-strengthened with anchored CFRP U-strips (2016) Composite Structures, 144, pp. 57-79; Chen, Q., Andrawes, B., Sehitoglu, H., Thermomechanical testing of FeNiCoTi shape memory alloy for active confinement of concrete (2014) Smart `Materials and Structures, 23 (5), p. 055015; (1993) CEB-FIB Model Code 1990 (CEB-FIB MC90), , Lausanne, CEB-FIB, Bulletin D’Information, No. 215; Czaderski, C., Shahverdi, M., Brönnimann, R., Feasibility of iron-based shape memory alloy strips for prestressed strengthening of concrete structures (2014) Construction and Building Materials, 56, pp. 94-105; (2013) ABAQUS 6.13 Documentation Collection, , Providence, RI, Dassault Systèmes; Deng, Z., Li, Q., Sun, H., Behavior of concrete beam with embedded shape memory alloy wires (2006) Engineering Structures, 28 (12), pp. 1691-1697; Dommer, K., Andrawes, B., Thermomechanical characterization of NiTiNb shape memory alloy for concrete active confinement applications (2012) ASCE Journal of Materials in Civil Engineering, 24 (10), pp. 1274-1282; Dong, J., Wang, Q., Guan, Z., Structural behaviour of RC beams with external flexural and flexural-shear strengthening by FRP sheets (2013) Composites: Part B, 44 (1), pp. 604-612; Dong, Z., Klotz, U.E., Leinenbach, C., A novel Fe-Mn-Si shape memory alloy with improved shape recovery properties by VC precipitation (2009) Advanced Engineering Materials, 11 (1-2), pp. 40-44; Duerig, T.W., Melton, K.N., Proft, J.L., Wide hysteresis shape memory alloys (1990) Engineering Aspects of Shape Memory Alloys, pp. 130-136. , Duerig T.W., Melton K.N., Stockel D., (eds), Oxford, Butterworth-Heinemann, In:, (eds; El-Hacha, R., Rizkalla, S.H., Near-surface-mounted fiber-reinforced polymer reinforcements for flexural strengthening of concrete structures (2004) ACI Structural Journal, 101 (5), pp. 717-726; El-Tawil, S., Ortega-Rosales, J., Prestressing concrete using shape memory alloy tendons (2004) ACI Structural Journal, 101 (6), pp. 846-851; Fang, C., Zheng, Y., Chen, J., Superelastic NiTi SMA cables: Thermal-mechanical behavior, hysteretic modelling and seismic application (2019) Engineering Structures, 183, pp. 533-549; Gangi, M., Jone, M., Liesen, J., (2018) Evaluation of repair techniques for impact-damaged prestressed beams, , Virginia Polytechnic Institute and State University, Blacksburg, VA, May,.

An inclined plane of curvature is also considered (with respect to the horizontal plane) in order to account for a slope in the cross-section plane. Additionally, a finite stiffness of diaphragmatic plates has been introduced in the formulation in order to compare with the beam models where rigid diaphragms are considered, as usually is assumed in practice. The numerical method employed for the 1D beam formulation is based on Isogeometric tools (NURBS) while the 3D shell or solid models are developed in Finite Element commercial software for composite cross sections with diaphragms. The influence of friction on the contact interaction between the concrete and steel parts is also considered. The number of intermediate diaphragms is determined according to commonly used bridge design guidelines and the results are compared to the developed arrangements in order to assess the overall structural behavior of bridge decks. Straight or curved beam models with open or closed composite cross sections of full (1D proposed beam) or partial material-bonding (3D solid/shell models) and various arrangements of intermediate diaphragms and materials have been studied. © 2020 Elsevier Ltd","Diaphragms; Distortion; Finite element method; Friction; Guidelines; Higher-order-beam-theories; Warping","Composite bridges; Design; Diaphragms; Distortion (waves); Friction; Numerical methods; Commercial software; Composite cross section; Contact interaction; Guidelines; Higher-order beam theories; Intermediate diaphragm; Structural behaviors; Warping; Finite element method",,,,,"Alexander von Humboldt-Stiftung","This work is part of a research project funded by Alexander von Humboldt Foundation .",,,,,,,,,,"Vlasov, V., Thin Walled Elastic Beams (1961), second ed.

The analysed structure is made of sandwich panels, which consist of glass fibre reinforced polymer (GFRP) multi-layered laminate faces and a PET foam (obtained from recycling) core. The dimensions of the segment cross-section are the same as for the target footbridge; however, span length was reduced to 3 m. The experimental tests were conducted in a laboratory of the Faculty of Ocean Engineering and Ship Technology at Gdansk University of Technology. A single vertical force was generated by a hydraulic cylinder and was applied to the platform of the structure. The experimental tests were supported by numerical analyses performed in Femap with NX Nastran software by means of the finite element method (FEM). Results obtained in the computational model were compared with results from experiments. Thus, the numerical model was validated and the obtained conclusions were used in the next step of the design process of a composite footbridge with a span length of 14.5 m. © 2020 Tomasz Ferenc et al., published by Sciendo.","GFRP laminates; numerical modelling; polymer composites; sandwich structure; Validation","Computation theory; Computational methods; Engineering education; Fiber reinforced plastics; Footbridges; Numerical methods; Numerical models; Ocean engineering; Polyethylene terephthalates; Software testing; Computational model; Design of composites; Experimental test; Glass fibre reinforced polymers; Hydraulic cylinders; Multi-layered laminates; Polymer composite; Validation process; Design",,,,,,,,,,,,,,,,"1.

The component model was established by ABAQUS, and the experiment was conducted to analyze stress amplitude of easily fatigue cracking areas of orthotropic steel box girder with and without the supporting member. In addition, the fatigue life was analyzed and predicted. The comparison results show that the finite element analytical results are in good agreement with the experimental results. The reduced proportion of stress amplitude of U rib, T rib grooves and mid-span of top plate of orthotropic steel box girder range from 40% to 60% and 20% to 40%, respectively. The analytical results show that the stress amplitude of orthotropic steel box girder can be reduced by the similar extent with the addition of the same supporting member under different loading pressure; The supporting member can improve the fatigue life of orthotropic steel box girder pertinently, which is simple in construction and low in cost, and can provide suggestions for solving fatigue problem of orthotropic steel box girder in engineering practice. © 2020, Korean Society of Civil Engineers.","Fatigue life; Orthotropic steel box girder; Reduced proportion of; Stress amplitude; stress amplitude; Supporting member","Box girder bridges; Cost engineering; Orthotropic plates; Steel structures; Stress analysis; Analytical results; Comparison result; Engineering practices; Fatigue cracking; Fatigue problems; Loading pressures; Orthotropic steel box girders; Stress amplitudes; Fatigue of materials",,,,,"National Natural Science Foundation of China, NSFC: 51078078","This study was supported by the National Natural Science Foundation of China (Grant No. 51078078).

The presented model is capable of capturing non-linearity in both the structure and soil, in addition to considering far-field soil response. The model is simple enough to be used for practical purposes. On the other hand, many aspects of seismic behaviour of IABs are unclear, due to complicated soil–structure interaction. Using the presented model, a parametric study is performed to identify the effects of bridge length, abutment type and soil type on seismic behaviour of IABs.

A 32-m simply supported box girder bridge used in the Beijing-Shanghai high-speed railway is selected as the prototype for designing and constructing a scaled model test with 10:1 geometric similarity ratio. Both experimental tests and finite element analyses were carried out to verify the similarity relationship between the model and prototype. The test result shows that the scaled model can predict the structural vibration and noise of the prototype, as long as the similarity constants between the prototype and scaled model are correctively determined. Furthermore, a standard finite element analysis model for the scaled model is built. Based on the sensitivity analysis, the model parameters for finite element analysis are updated by minimizing the errors between the measured and calculated modes. The computational results show that the updated model based on the local parameters partitioning works best, and the precision of the modal frequency calculated is noticeably improved after updating, with the average relative error reduced from 5.46% to 3.09%, and the difference of the peak values reduced from 0.358×103m/s2 to 0.189×103m/s2. The calculated dynamic response of the finite element model after updating is basically in line with experimental results, indicating that the updated model can better reflect the dynamic properties of the scaled box girder model. The updated finite element model is useful both for verification with the model test result and for reliable prediction of the dynamic characteristics of the prototype. © 2020 World Scientific Publishing Company.","box girder; high-speed railway; model updating; scaled model test; sensitivity analysis; Vibration prediction","Beams and girders; Box girder bridges; Forecasting; Railroad transportation; Railroads; Sensitivity analysis; Steel bridges; Structural dynamics; Testing; Average relative error; Computational results; Dynamic characteristics; High - speed railways; Simply supported box girders; Standard finite element; Structural vibrations; Vibration predictions; Finite element method",,,,,"National Natural Science Foundation of China, NSFC: 51868023, 51978264; Education Department of Jiangxi Province","This work was supported by the National Natural Science Foundation of China (Grant nos. 51868023 & 51978264) and the Major Project of the Education Department of Jiangxi Province (Grant no.

Here, two state-space equations for the left- and right-hand maglev vehicles are derived, considering the equations of motion of vehicles, governing equations of currents, linear feedback controls and state observers. By employing the conventional finite element method, the equation of motion for the variable cross-section continuous girder bridge with three spans is simulated. To solve these three coupled equations, this study adopted a new separated iterative approach based on the precise integration method and the Newmark-β method. The total virtual work conducted by the inertial loads, damping loads, elastic loads and fluctuating electromagnetic loads are calculated to conveniently assemble the global mass matrix, damping matrix, stiffness matrix and coefficient matrices of fluctuating electromagnetic forces in the maglev vehicles. The numerical studies indicate that the vertical interactions play dominant roles in the 3D maglev vehicles-bridge system, and the passing maglev vehicles on the bridge have little influence on the lateral motions of the vehicle on the other line due to the adequate lateral stiffness of the bridge. © 2020, Korean Society of Civil Engineers.","EMS-type maglev vehicles;

In this study, by using the split Hopkinson pressure bar (SHPB) technique, the dynamic compressive mechanical behavior of this material was experimentally investigated at four different temperatures of 25°C, 300°C, 500°C, and 700°C and three strain rates of 1,000, 3,000, and 5,000 s-1. Quasi-static compressive test under the strain rate of 0.001 s-1 was also carried out in the material test system at temperatures of 25°C, 300°C, 500°C, and 700°C. Test results showed that flow stress of ASTM A240/A240M 304 stainless steel decreases with temperature increase but increases with increase of strain rate. Moreover, temperature becomes the main factor affecting material performance at 700°C. Based on the measured stress-strain curves, the modified Johnson-Cook model was proposed as the constitutive stress-strain model for ASTM A240/A240M 304 stainless steel. It was shown that the proposed modified Johnson-Cook model is in good agreement with the experimental results. According to the proposed modified Johnson-Cook model, a user subroutine (VUMAT for Abaqus/Explicit) for ASTM A240/A240M 304 written in Fortran was developed and verified. The proposed constitutive model and user subroutine of ASTM A240/A240M 304 stainless steel can be used for structural analysis and finite-element analysis under high strain rates and elevated temperature. © 2020 American Society of Civil Engineers.","Modified Johnson-Cook model; Split Hopkinson pressure bar (SHPB); Strain rate effect; Structural stainless steel; Temperature effect","Austenitic stainless steel; Bridge decks; Dynamics; Stress-strain curves; Thermal effects; Compressive mechanical behavior; Dynamic mechanical behavior; Johnson-Cook model; Material performance; Split hopkinson pressure bar techniques; Split Hopkinson pressure bars; Strain rate effect; Temperature increase; Strain rate; civil engineering; compressive strength; dynamic response; finite element method; numerical model; steel structure; strain rate; structural response; temperature effect",,,,,"2015CB058001; National Natural Science Foundation of China, NSFC: 51678018","This research was supported by the National Natural Science Foundation of China (No. 51678018) and the National Key Basic Research and Development Program of China (No. 2015CB058001).",,,,,,,,,,"Baddoo, N.R., Stainless steel in construction: A review of research, applications, challenges and opportunities (2008) J.

Two methods of analysis are adopted. The first and second method is static and dynamic analysis respectively. The results of static analysis shown that HB-AH1 vehicle is the heavy vehicle, which was passed on the bridges structures and it can be caused higher bending moment and vertical displacement. Whereas, Hn-44 vehicle is the light vehicle comparing with other types of vehicles. Concrete slab bridge produced the maximum value of vertical displacement and concrete box girder bridge appeared minimum value of vertical displacement. The results of dynamic analysis illustrated that concrete slab bridge model had natural frequency (3.52 Hz), which was less than dynamic frequency (4.64 Hz), indicating that bridge model had not enough stiffness and elasticity. Therefore, this type of bridge structure was not suitable to carry heavy traffic loads. The dynamic frequency of steel bridge model was 4 Hz. This value was less than a natural frequency value (6.82 Hz), showing that the bridge model had suitable stiffness and elasticity. Concrete bridge model had 8.58 Hz of natural frequency, which was more than dynamic frequency (4.12 Hz), resulting that bridge structure has enough stiffness, elasticity, resistance for loads, and bearing capacity. This study recommended that using concrete box girder bridges model in the building of bridges structures. © School of Engineering, Taylor’s University","Bending moment; Frequency; Slab bridge; Steel bridge; Vehicles; Vertical displacement",,,,,,,,,,,,,,,,,"Naser, A.F., Three-dimensional analysis of girder cross-section shapes effects on static properties of bridges models (2017) Journal of Al-Qadisiyah for Engineering Science, 10 (3), pp. 244-258; Meshrama, S., Ramtekeb, P., Effect of vehicle velocity on the dynamic amplification factor for a simply supported T-beam bridge (2015) International Journal of Innovative and Emerging Research in Engineering, 2 (5), pp. 102-108; Mary, D., John, B., Anagha, S., (2012) Continuous Prestressed Concrete Girder Bridges, Vol. 1: Literature Review and Preliminary Designs, , Project performed in cooperation with the Texas Department of Transportation and the Federal Highway Administration; (2001) Bridge Detailing Manual, , Texas Department of Transportation TDT; Eriksson, J., Jonsson, A., (2017) Modeling Techniques for Post-Tensioned Concrete Slab Bridges, , Master Thesis.

Firstly, when a span-scale girder segment is temporarily stored in the open air, temperature gradients will significantly increase the maximum reaction force on temporary supports and cause local buckling at the bottom of the girder segment. Secondly, due to the temperature difference of the girder segments before and after girth-welding, some residual thermal deflections will appear on the girder segments because the boundary conditions of the structure are changed by the girth-welding. Thirdly, the thermal expansion and thermal bending of girder segments will cause movement and rotation of bearings, which must be considered in setting bearings. We propose control measures for these problems based on finite element method simulation with field-measured temperatures. The local buckling during open-air storage can be avoided by reasonably determining the appropriate positions of temporary supports using analysis of overall and local stresses. The residual thermal deflections can be overcome by performing girth-welding during a period when the vertical temperature difference of the girder is within 1 °C, such as after 22:00. Some formulas are proposed to determine the pre-set distances for bearings, in which the movement and rotation of the bearings due to dead loads and thermal loads are considered. Finally, the feasibility of these control measures in the placement of span-scale girder segments on a real continuous girder was verified: no local buckling was observed during open-air storage; the residual thermal deflections after girth-welding were controlled within 5 mm and the residual pre-set distances of bearings when the whole continuous girder reached its design state were controlled within 20 mm. © 2020, Zhejiang University and Springer-Verlag GmbH Germany, part of Springer Nature.","Construction process; Control measures; Span-scale girder segments; Steel box girder; Thermal effects; U445.467","Buckling; Steel bridges; Steel structures; Thermal expansion; Welding; Continuous girders; Finite element method simulation; Measured temperatures; Steel box girders; Temperature differences; Temporary support; Thermal deflections; Vertical temperature differences; Box girder bridges",,,,,"National Natural Science Foundation of China, NSFC: 51578496, 51878603; Natural Science Foundation of Zhejiang Province, ZJNSF: LZ16E080001","Project supported by the National Natural Science Foundation of China (Nos. 51578496 and 51878603) and the Zhejiang Provincial Natural Science Foundation of China (No. LZ16E080001)",,,,,,,,,,"Ding, Y.L., Li, A.Q., Temperature-induced variations of measured modal frequencies of steel box girder for a long-span suspension bridge (2011) International Journal of Steel Structures, 11 (2), pp. 145-155; Ding, Y.L., Zhou, G.D., Li, A.Q., Thermal field characteristic analysis of steel box girder based on long-term measurement data (2012) International Journal of Steel Structures, 12 (2), pp. 219-232; Emerson, M., (1979) Bridge Temperatures for Setting Bearings and Expansion Joints, SR479. , Technical Report, Transport and Road Research Laboratory, Wokingham, UK; Kim, S.H., Cho, K.I., Won, J.H., A study on thermal behaviour of curved steel box girder bridges considering solar radiation (2009) Archives of Civil and Mechanical Engineering, 9 (3), pp. 59-76; Kim, S.H., Park, S.J., Wu, J.X., Temperature variation in steel box girders of cable-stayed bridges during construction (2015) Journal of Constructional Steel Research, 112 (1), pp. 80-92; Kowalski, R., Głowacki, M., Wróblewska, J., Thermal bowing of reinforced concrete elements exposed to non-uniform heating (2018) Archives of Civil Engineering, 64 (4), pp. 247-264; Kromanis, R., Kripakaran, P., Harvey, B., Long-term structural health monitoring of the Cleddau Bridge: evaluation of quasi-static temperature effects on bearing movements (2016) Structure and Infrastructure Engineering, 12 (10), pp. 1342-1355; Lee, J.H., Jeong, Y.S., Kim, W.S., Buckling behavior of steel girder in integral abutment bridges under thermal loadings in summer season during deck replacement (2016) International Journal of Steel Structures, 16 (4), pp. 1071-1082; Li, C.X., Yang, N., Zhang, Y.P., The sunlight thermal gradient of the steel box girder and the deformation of the last girder in incremental launching construction of Hangzhou Jiangdong Bridge (2009) Journal of Transport Science and Engineering, 25 (1), pp. 39-44. , (in Chinese; Lucas, J.M., Berred, A., Louis, C., Thermal actions on a steel box girder bridge (2003) Proceedings of the Institution of Civil Engineers-Structures and Buildings, 156 (2), pp. 175-182; Malik, P., Kadoli, R., Ganesan, N., Effect of boundary conditions and convection on thermally induced motion of beams subjected to internal heating (2007) Journal of Zhejiang University-SCIENCE A, 8 (7), pp. 1044-1052; Miao, C.Q., Shi, C.H., Temperature gradient and its effect on flat steel box girder of long-span suspension bridge (2013) Science China Technological Sciences, 56 (8), pp. 1929-1939; (2003) Code for Design of Steel Structures, GB50017-2003.

In Louisiana, most of these culverts were constructed using old standard details. Following current load rating procedures for these culverts often yields unacceptable load rating factors, even though their performance is acceptable with no signs of distress. The discrepancy between calculated load rating and observed performance of the culverts is investigated for eight selected culverts by field live load testing and finite element modeling. Each culvert was instrumented using a 48-sensor structural health monitoring system before a loaded truck was driven on the culvert along three different load paths to collect field data. Three-dimensional (3D) finite element (FE) models were calibrated using the recorded field data, and an HL-93 design truck and 10 legal trucks such as Type 3-3 were used to load the calibrated FE models to obtain culvert specific load rating factors. Acceptable rating factors were obtained for all eight culverts. The rating methodology, rating factors, and recommendations for rating culverts are presented in this paper. © 2020 American Society of Civil Engineers.","Cast-in-place; Culvert; Load rating; Load test","Cast in place concrete; Concrete testing; Finite element method; Load testing; Reinforced concrete; Structural health monitoring; Trucks; Cast in place; Concrete box; Current loads; Load paths; Load ratings; Specific loads; Structural health monitoring systems; Threedimensional (3-d); Culverts",,,,,"Louisiana Transportation Research Center, LTRC: 16-3ST","This research is sponsored by the LTRC (Louisiana Transportation Research Center), under Project No. 16-3ST.

To simplify the analysis of such systems, general elastic and continuous structure theory is applied to the asphalt pavement on steel bridge decks to determine the magnitude of the strain. Large differences in mechanical results have been previously obtained in assessments of steel bridge deck pavements. Few studies have focused on the mechanical state and time-dependent response of a realistic steel bridge deck wearing surface because of the difficulty of measuring the strain of the pavement on a steel deck of a long-span bridge that is in service. This study performed static and dynamic loading tests on an actual long-span steel bridge and analyzed the characteristics of the time-dependent strain response of the bridge deck wearing surface. The results demonstrate that the asphalt wearing surface exhibited significant loading time and rate-dependent characteristics under both static and dynamic loading conditions. The test analysis results also revealed that the axle load, vehicle speed, and longitudinal slope of the bridge had significant effects on the mechanical responses of the bridge deck wearing surface. Based on a comparison between the finite element numerical simulation results and the measurements obtained from testing the actual bridge, the magnitudes of the mechanical strain responses of the wearing surface on a steel bridge deck under the dynamic wheel load of a vehicle were analyzed assuming that the wearing surface is elastic and that the elastic modulus can be determined from a four-point bending test. However, the cumulative effect of plastic deformation must be considered when analyzing the fatigue damage of a permanent wearing surface. © 2020 ASTM International.

To predict the response, the theory of viscoelasticity is employed and the computational framework is implemented into a 3D multilayer model to use in finite element method. Three asphalt depths have been assumed and laid under repeated loading. The load passes are kept to 500 pulses. Study on the goodness of cycle numbers shows 200 pulses are good enough and the response has been converged before 200. The simulations show that viscoelastic behaviour is more sensitive to thickness variations, and the tensile strain and compressive stress under the asphalt reduces faster than conventional designing assumptions; however, the viscoelastic final response is still greater. The results reveal that the base course is greatly influenced by asphalt thickness variations so that a 10 cm viscoelastic overlay causes basecourse to bear stress eight times greater than that of elastic assumption. The resulting compressive stress above the subgrade is significantly affected by asphalt thickness and stress-induced history. Moreover, the results show that the viscoelastic behaviour develops the stress overlapping zone. © 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group.","hot mix asphalt; overlapping zone; thickness variations; thin asphalt overlay; Viscoelasticity","3D modeling; Asphalt concrete; Bridge decks; Compressive stress; Computation theory; Concrete mixtures; Tensile strain; Viscoelasticity; Asphalt overlay; Computational framework; Hot mix asphalt; Overlapping zones; Rate-dependent behaviour; Thickness variation; Viscoelastic analysis; Viscoelastic behaviour; Finite element method",,,,,,,,,,,,,,,,"Abu Al-Rub, R.K., Masad, E.A., Graham, M., (2010) Physically-based model for predicting the susceptibility of asphalt pavements to moisture-induced damage, , Texas: Southwest University Transportation Center, SWUTC/09/476660-0012-1; Abu Al-Rub, R.K., Comparing finite element and constitutive modelling techniques for predicting rutting of asphalt pavements (2011) International Journal of Pavement Engineering, 13 (4), pp. 322-338; Al-Qadi, I., Dynamic analysis and in situ validation of perpetual pavement response to vehicular loading (2008) Transportation Research Record: Journal of the Transportation Research Board, 2087, pp. 29-39; Al-Qadi, I., Wang, H., Tutumluer, E., Dynamic analysis of thin asphalt pavements by using cross-anisotropic stress-dependent properties for granular layer (2010) Transportation Research Record: Journal of the Transportation Research Board, 2154, pp. 156-163; (1993) AASHTO guide for design of pavement structures, 1. , Washington: AASHTO; (1981) Thickness design–asphalt pavements for highways and streets (No. 1), , Asphalt Institute; Brinson, H.F., Brinson, L.C., (2015) Polymer engineering science and viscoelasticity, , Berlin: US Springer; Chehab, G.R., (2003) Characterization of asphalt concrete in uniaxial tension using a viscoelastoplastic continuum damage model, 72, pp. 315-355. , Association of Asphalt Paving Technologists Technical Sessions, Lexington: USA; Chen, Y., (2009) Viscoelastic modeling of flexible pavement, , Thesis (PhD), University of Akron; Chen, R.S., Tu, C.Y., Tsai, H.S., The effects of moisture upon the optimal temperature path of the viscoelastic symmetric composite laminates after post cure (1993) Journal of Composite Materials, 27 (16), pp. 1578-1597; Christensen, R., (2012) Theory of viscoelasticity: an introduction, , Cambridge, MA: Elsevier; Collop, A., Scarpas, A., Kasbergen, C., de Bondt, A., Development and finite element implementation of stress-dependent elastoviscoplastic constitutive model with damage for asphalt (2003) Transportation Research Record: Journal of the Transportation Research Board, 1832, pp. 96-104; Dai, Q., You, Z., Investigation of linear and damage-coupled viscoelastic properties of sustainable asphalt mixture using a micromechanical finite element approach (2007) Analysis of Asphalt Pavement Materials and Systems: Emerging Methods, 1, pp. 22-32; Darabi, M.K., Thermodynamic-based model for coupling temperature-dependent viscoelastic, viscoplastic, and viscodamage constitutive behavior of asphalt mixtures (2012) International Journal for Numerical and Analytical Methods in Geomechanics, 36 (7), pp. 817-854; Darabi, M.K., A thermodynamic framework for constitutive modeling of time-and rate-dependent materials.

The in-plane structural behaviour and strength of ten specimens with different local damages are investigated experimentally. A finite element (FE) model for damaged steel tubular arches is established and is validated by the test results. The FE model is then used to conduct parametric studies on effects of the damage location, depth and length on the strength of steel arches. The experimental results and FE parametric studies show that effects of damages at the arch end on the strength of the arch are more significant than those of damages at other locations of the arch, and that effects of the damage depth on the strength of arches are most significant among those of the damage length. It is also found that the failure modes of a damaged steel tubular arch are much related to its initial geometric imperfections. The experimental results and extensive FE results show that when the effective cross-section considering local damages is used in calculating the modified slenderness of arches, the column bucking curve b in GB50017 or Eurocode3 can be used for assessing the remaining in-plane strength of locally damaged parabolic steel tubular arches under uniform compression. Furthermore, a useful interaction equation for assessing the remaining in-plane strength of damaged steel tubular arches that are subjected to the combined bending and axial compression is also proposed based on the validated FE models. It is shown that the proposed interaction equation can provide lower bound assessments for the remaining strength of damaged arches under in-plane general loading.

Design/methodology/approach: A coupled, transient heat and moisture transfer analysis has been conducted to investigate the effect of panel connections in the hygrothermal behavior of facade panels. Governing partial differential equations for the coupled heat and moisture transfer were formulated. Four panel connections proposed by pre-cast/pre-stressed concrete institute were modeled for the ultra-high performance fiber-reinforced concrete facade panel as illustrations and a finite element method was used to solve the numerical models. Findings: The results of heat transfer analysis showed that steel connections could significantly reduce the thermal resistivity of facade panels by converging heat fluxes and acting as thermal bridges within facade panels. The results also showed that the maximum heat flux in the steel connector of the panel to foundation connection was 10 times higher compared to the other connections. Also, the results of moisture transfer showed that air gaps between the panels had higher moisture flux compared to the other layers in the models. The results show the significant importance of panel connections in the energy performance analysis of facade systems. They also highlight the importance of devising novel connection designs and materials that consider the transient, coupled heat and moisture transfer in the connections to effectively exploit the potential opportunities provided by innovative facade systems to improve building energy efficiency. Originality/value: This paper, for the first time, investigates the effect of panel connections in the hygrothermal performance of building facade systems using a coupled, transient heat and moisture transfer analysis. © 2020, Emerald Publishing Limited.","Coupled heat and moisture transfer;

To determine these reasons, a comprehensive site investigation and a wide variety of tests were implemented, which included geophysical tests, in situ tests, laboratory tests, pile integrity detection, and numerical analysis with the finite element method (FEM). The results revealed that the soil of the low-angle slope was the potentially low-expansive clay soil. The reduction in soil shear strength deriving from seasonal wet-dry cycles and river-level variations led to the instability and failure of the low-angle low-expansive soil slope, which triggered the collapses of the soil slope and lots of fractures in the piles of the bridge foundation. The typical characteristics of the instability and failure of the low-angle low-expansive soil slope were tractional detachment and slow sliding. © 2020 Yongzheng Qi et al.",,,,,,,"2018ZD093; Hohai University: 2019008","This work was supported by the Key Laboratory of Ministry of Education for Geomechanics and Embankment Engineering, Hohai University (2019008), and the Science and Technology Project for Construction System in Jiangsu Province (2018ZD093).",,,,,,,,,,"Donald, P., Hammes, C., Frami, J., (2001) Foundation Design: Principles and Practices, , Prentice Hall, Upper Saddle River, NJ, USA;

It includes dynamics, pseudo-dynamics regularization, elastic actuators and automatic stress calibration. Dynamics and pseudo-dynamics are used to perform transient structural analysis and the setting-up of very unstable structures. Elastic actuators allow pre-stressing structural members for the iterative structural design and cables natural length definition. Automatic stress calibration comprises continuous cables in complicated structures without sliding contact devices. The formulation is applied to model main cables of suspended bridges passing through saddle points. Inertial terms are introduced by an alternative mathematical way. Two simple examples are used to validate all aspects of the proposed formulation. Finally, a representative application is performed, i.e., the numerical design and analysis of a very long span suspension bridge by the proposed strategy. © 2020.

As an essential index of the structural performance, the residual load-carrying capacity of a damaged ship hull girder is particularly important for assessing the consequence of an accidental event. In this regard, considerable effort has been devoted to develop an efficient calculation methodology that can provide a reliable estimation of the residual ultimate bending strength of a damaged hull girder. However, the actual hull girder collapse can involve multiple load cycles, such as that experienced in a rough sea. The cyclic loading may lead to the onset of plasticity and local buckling, which can permanently reduce the overall strength of the ship hull. Hence a cyclic progressive collapse method is proposed. It follows the major assumptions and procedure embedded in the original Smith method with an extended capability to re-formulate the load-shortening curve of structural elements when an unloading or reloading is activated. A case study is carried out to predict the cyclic bending response of an asymmetrically damaged box girder model with various extents. The effect of the instantaneous neutral axis rotation is accounted for. Additionally, equivalent nonlinear finite element analysis is performed as a validation. © 2020 Taylor and Francis Group, London.",,"Accidents; Bending strength; Box girder bridges; Curve fitting; Cyclic loads; Offshore oil well production; Offshore structures; Unloading; Accidental event; Damaged ship hulls; Non-linear finite-element analysis; Progressive collapse; Residual load-carrying capacity; Structural elements; Structural performance; Ultimate bending strengths; Hulls (ship)",,,,,,,,,,,,,,,,"(2000) Ultimate Strength.

A typical structure of the system takes an H-bridge inverter with an inductor-capacitor-inductor (LCL) resonant filter to realize a constant track current supplying changeless energy to the second side. However, the output voltage total harmonic distortion (THD) of the inverter increases, which causes the increase of output current circulation, when using voltage width control method to eliminate source voltage fluctuating. Therefore, a two-stage converter is proposed to optimize the output current circulation. The two-stage IPT system is composed of a boost converter cascaded with an H-bridge resonant inverter. The boost converter is employed to provide a higher and stable DC bus voltage. The H-bridge resonant inverter operates in a fixed width with a constant switching frequency. With the proposed topology, the THD of the high frequency voltage maintains the minimum value to realize minimum output current circulation in the LCL filter. The soft switching is realized to reduce the losses. Furthermore, expressions of coil and track model are presented by combining the theoretical analysis and finite element analysis (FEA). The experimental results show that over 76.6% efficiency is demonstrated in conditions of an 800 W load at the 14% source voltage fluctuation and the maximum efficiency was 78.6 %. The range of efficiency variation was 2% compared to a full-bridge system with voltage pluse-width control of which was 4.6%. © 2013 IEEE.","finite element analysis (FEA); Inductive power transfer (IPT); material handling; soft switching; THD optimization","Bridge circuits; DC-DC converters; Electric inverters; Energy transfer; Harmonic distortion; Inductive power transmission; Materials handling; Wave filters; Constant switching frequency; High-frequency voltage; Inductive power transfer systems; Inductive powertransfer (IPT); Material handling; Power loss reduction; THD optimization; Total harmonic distortion (THD); Finite element method",,,,,"National Natural Science Foundation of China, NSFC: 51807057","The National Natural Science Foundation of China under Grant 51807057 (Theoretical Research on Key Points of Modular Combined DC Converter for Seafloor Observation Network).",,,,,,,,,,"Lu, F., Zhang, H., Zhu, C., Diao, L., Gong, M., Zhang, W., Mi, C.C., A tightly coupled inductive power transfer system for low-voltage and high-current charging of automatic guided vehicles (2019) IEEE Trans.

The compressive performance of PFRP tube depends on many factors such as fibre type, fibre content, and orientation of fibre layers, cross-section, thickness and height of the column member. In this study, concentric compressive testing was conducted using PFRP short columns. Based on the fibre orientation and thickness, the samples were divided into two groups of tubes in a square shape and two groups in a circular shape. The height of columns is designed to keep the slenderness ratio (length/lateral dimension) of 5. The axial behaviour of FRP columns was simulated using STRAND7 finite element software package. The laminate method was followed to define the mechanical properties of the FRP material. Failure was investigated by using the Tsai-Wu failure criterion. The experimental results show that the failure mode of the hollow square tube was either local buckling or corner splitting at the mid-height followed by buckling. Although both types of circular tubes failed in a similar way by crushing one end with high noise, followed by separation of the crushed end into strips, the stiffness and the load capacity of PFRP column was higher for the profiles with fibres oriented close to the axial direction. The numerical results are in close agreement with the peak value of the experimental results. This can be extended to study the effects of all factors that influence the axial behaviour of PFRP columns numerically. © 2020, Springer Nature Singapore Pte Ltd.","Axial behaviour; Buckling; Column; Finite element; Pultruded FRP tube","Bridge decks; Buckling; Columns (structural); Fiber reinforced plastics; Finite element method; Reinforcement; Tubes (components); Axial behaviour; Compressive performance; Fibre reinforced polymers; Finite element software; Frp tubes; Instability condition; Numerical investigations; Tsai-Wu failure criterion; Fibers",,,,,,,,,,,,,,,,"Abdelkarim, O.I., Elgawady, M.A., Analytical and finite-element modeling of FRP-concrete-steel double-skin tubular columns (2015) J Bridge Eng, 20 (8); Barbero, E., Tomblin, J., A phenomenological design equation for FRP columns with interaction between local and global buckling (1994) Thin-Walled Struct, 18 (2), pp. 117-131; Barbero, E.J., (2017) Introduction to Composite Materials Design, , 3rd edn.

This paper aims to evaluate the strength and ductility of thin-walled steel tubular circular columns with uniform thickness (BC) and graded thickness (BGC) under bidirectional cyclic lateral loading in the presence of constant axial force. The analysis is carried out using a finite-element model (FEM) which is substantiated based on the experimental results in the literature. Then, the proposed BGC column with size and volume of material equivalent to the BC column is investigated. As a part of this research, a comprehensive parametric study is carried out to investigate the effects of main design parameters including: radius-to-thickness ratio parameter (Rt), column slenderness ratio parameter (λ), magnitude of axial load (P/Py), and number of loading cycles (N) on the strength and ductility of both BC and BGC columns under bidirectional cyclic lateral loading. Finally, design formulae of ultimate strength and ductility of BC and BGC columns are derived. © 2019 Elsevier Ltd","Bidirectional cyclic loading; Buckling; Circular graded-thickness; Ductility; Strength; Thin-walled","Buckling; Cyclic loads; Ductility; Thin walled structures; Bi-directional cyclic loading; Circular graded-thickness; Column slenderness; Cyclic lateral loading; Radius-to-thickness ratio; Strength; Strength and ductilities; Thin-walled; Loading",,,,,,,,,,,,,,,,"Jaiswal, K., Bausch, D., Rozelle, J., Holub, J., McGowan, S., Hazus® Estimated Annualized Earthquake Losses for the United States (No. FEMA P-366) (2017); Miller, D.K., Lessons learned from the Northridge earthquake (1998) Eng.

A recurring problem with this type of bridge is cracking in the longitudinal joints between adjacent beams, which allows water and salt leakage through the joint and reflective cracks in the wearing surface. In this paper, a comprehensive review of the past literature is presented to identify potential reasons joint cracking is induced. An innovative connection was then designed with a wide joint, shrinkage-compensated concrete, a rough interface between the joint and box girder, and reinforcing steel that crosses the interface between the joint and box beam, to overcome the problems mentioned in the literature review. The design was evaluated on four small-scale specimens designed with different amounts of transverse reinforcement. The specimens were monitored for early-age joint behavior and then tested for ultimate capacity. A three-dimensional (3D) finite-element model (FEM) was developed to simulate early-age joint behavior and determine the stress distribution in the joint and at the interface between the joint and the box beam concrete. The shrinkage, temperature, and strain data collected during the early-age monitoring were used to validate the FEM. Both experimental and finite-element analysis results indicate that the innovative joint showed good performance in resisting joint cracking when subjected to joint material expansion and the heat of hydration. The results also indicate that the expansion of the joint material formed a compression-dominated joint, which would naturally inhibit crack formulation. The transverse reinforcing steel across the interface resisted the expansion of the joint material and resulted in some additional transverse compression in the joint. © 2019 American Society of Civil Engineers.","Adjacent box beam; Early-age joint behavior; Finite-element analysis; Shrinkage-compensated concrete","Box girder bridges; Expansion; Finite element method; Hydration; Joints (structural components); Reinforced concrete; Box beam; Joint behavior; Longitudinal joint; Material expansion; Reinforcing steels; Three-dimensional (3D) finite element models; Transverse compression; Transverse reinforcement; Shrinkage",,,,,,,,,,,,,,,,"(2012) AASHTO LRFD Bridge Design Specifications, , AASHTO.

Three principles, i.e. no collapse after earthquake, good self-centering capacity, and no shear failure at joints, were put forward to define the feasible region of PT force according to the ultimate state. A calculation procedure was developed to determine the ultimate state and verified by a validated finite element model. With the ultimate state known, an analytical method was established to calculate the feasible region of PT force according to the three principles. Parametric analysis was conducted to quantitatively study the effects of eight common design parameters on the feasible region of PT force. A noniterative calculation method was further given to determine the feasible region of PT force for designers. The results show that the calculation procedure can accurately predict the characteristic values at the ultimate state. There are significant effects of the eight design parameters on the feasible region of PT force, which is actually controlled by the two former principles. The gravity loading can provide sufficient shear resistance at joints without shear keys in general. The feasible region of PT force is mainly distributed between 0.10 and 0.20 for precast segmental UHPC bridge columns with an area ratio of energy dissipation (ED) bars of more than 1.00%. The feasible region of PT force does not exist when the ED bar ratio is more than a critical value (i.e., 2.83% in this research). A noniterative and conservative calculation method to determine the feasible region of PT force can be obtained when the compression zone height of the bottom section at the ultimate state is equal to the wall thickness of the hollow section. © 2019","Bridge column; Feasible region; Finite element model; Post-tensioning force; Precast concrete; Segmental construction; Self-centering; Ultra-high performance concrete","Bridges; Energy dissipation; High performance concrete; Precast concrete; Bridge columns; Feasible regions; Posttensioning; Segmental constructions; Self centering; Ultra high performance concretes; Finite element method; bridge; column; concrete; design; energy dissipation; feasibility study; finite element method; force; loading; structural analysis; tension",,,,,"2017G006-C; National Natural Science Foundation of China, NSFC: 51438003","The work described in this paper was financially supported by the National Natural Science Foundation of China (Grant No. 51438003 ), the Project of Science and Technology Research and Development Plan of China Railway Corporation (Grant No. 2017G006-C ), and the Science and Technology Research Plan of China Railway Eryuan Engineering Group Corporation (Grant No. (19-21 ).",,,,,,,,,,"Mander, J.B., Cheng, C.T., (1997), Seismic resistance of bridge piers based on damage avoidance design.

Among many applications, CLSMs can be used for rapid and sustainable construction of bridge abutments. A study was undertaken to investigate the allowable bearing pressures of bridge sills over an abutment backfilled with CLSMs referred to as a “CLSM bridge abutment.” The study was conducted by the finite element method of analysis. The capability of the finite element computer code for analyzing the performance of a CLSM bridge abutment has been evaluated prior to this study. A series of finite element analyses were carried out to examine the effect of facing type, sill width, CLSM stiffness/strength, and foundation stiffness/strength on the load-carrying capacity of CLSM abutments. The allowable bearing pressures of CLSM abutments were determined based on results of the analytical study and two performance criteria: a limiting displacement criterion and a limiting linear strain criterion. In addition, a recommended procedure for determining the allowable bearing pressure is provided. © 2019 Elsevier Ltd","Allowable bearing capacity; Bridge abutments; Controlled low strength material (CLSM); Finite elements; Parametric study","analytical method; bearing capacity; bridge; finite element method; loading; parameterization; stiffness; strain; strength",,,,,,,,,,,,,,,,"(2013), ACI (American Concrete Institute).

In this experiment, asymmetrical loading was used to simulate the bridge differential settlement caused by soil settlement. The experimental results showed that the entire process could be divided into three stages: elastic stage, cracks developing stage, and failure stage. During these stages, cracks appeared at the bottom of the UHPC slab. Then, many microcracks appeared at the side of the UHPC slab. These microcracks appeared in the form of microcrack clusters, and the width of these cracks increased slowly. It indicated that UHPC had good crack-control ability. Finally, the main crack appeared at the bottom of the UHPC slab, and the transverse reinforcements yielded. It indicated that the reinforcement layout met the requirements of the failure mode of the specimen. For further analysis, the finite-element model (FEM) was established. And the results showed that the bending resistance of the joints could be effectively enhanced by increasing the free length of the joint or reducing the thickness of the joint. Based on this experiment and analysis, a nonconnected joint form between slabs and girders was put forward. And the detailed reinforcement scheme of this nonconnected joint form was given. This reinforcement scheme could serve as a reference for similar projects. © 2019 fib.

Therefore, various standards and studies have suggested physics-based models for predicting the time-dependent deflection of railway bridges. However, these approaches may be limited by model errors caused by uncertainties in various factors, such as material properties, creep coefficient, and temperature. This study proposes a new Bayesian method that employs both a finite element model and actual measurement data. To overcome the limitations of an imperfect finite element model and a shortage of data, Gaussian process regression is introduced and modified to consider both, the finite element analysis results and actual measurement data. In addition, the probabilistic prediction model can be updated whenever additional measurement data is available. In this manner, a probabilistic prediction model, that is customized to a target bridge, can be obtained. The proposed method is applied to a pre-stressed concrete railway bridge in the construction stage in the Republic of Korea, as an example of a bridge for which accurate time-dependent deflection is difficult to predict, and measurement data are insufficient. Probabilistic prediction models are successfully derived by applying the proposed method, and the corresponding prediction results agree with the actual measurements, even though the bridge experienced large downward deflections during the construction stage. In addition, the practical uses of the prediction models are discussed. © 2019 by the authors.

Secondary stiffeners are incorporated into the plate or shell formulation. In the free vibration analysis, these elements ignore inertia induced local deformation of plating between the secondary stiffeners. Oscillating motion causes inertia induced body load that locally deforms the plate. This local deformation may have a significant effect on the global modal frequencies of a deck structure. This paper presents a method for correcting ESL modal frequencies by modifying generalised mass and stiffness of the modes. The modification is based on the kinetic and strain energies of the local deformations. Energy components are derived from local consideration of plate in cylindrical bending under enforced support vibration. The method is validated in a case study of ship deck structure against shell mesh results, and good agreement is found. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.","deck; equivalent element; equivalent single layer; finite element method; Free vibration; stiffened panel","Bridge decks; Decks (ship); Deformation; Finite element method; Plates (structural components); Structural panels; deck; Equivalent elements; Equivalent single layers; Free vibration; Stiffened panel; Vibration analysis",,,,,,"This study was funded by Meyer Turku Oy.

The rotational torque in SRM and the biased flux used for producing electromagnetic force in AMB are generated simultaneously when the MBSRM works on the traditional switched reluctance excitation mode. First, the structure and working principle of the MBSRM were introduced. Second, its theoretical formulas of suspending forces were given and validated with the finite element analysis. Third, the proposed half-bridge converter is shown, and currents in the biased winding and three-phase armature windings of MBSRM are obtained by the magnetic field-circuit coupling simulation.

To study the shearing behaviour of a non-prismatic girder bridge with CSWs with concrete encasement (CSWC), experimental and analytical models were investigated. Experimental results show that concrete encasement contributes to the prevention of local buckling in CSWs; moreover, shear stress was found to be reduced by approximately 45% with the help of concrete encasement. The results also reveal that the theoretical ratios of shear force are in good agreement with the experimental results in the elastic stage and that the shear ratio of the CSWs increases rapidly with load, while that of the concrete-encased structures decreases, owing to yielding of the CSWs after cracking of the concrete encasement; the shear ratio of the CSWs then decreases with an increase in load, while that of the concrete-encased structures increases again after the CSWs yield. Finally, a reasonably thick concrete encasement that can effectively resist shear force is recommended, based on the analytical equations examined in this study. © 2018 ICE Publishing: All rights reserved.","composite materials;

The structure and work principle of the SLB-EMR are described particularly. Based on the magnetic equivalent circuit (MEC) method, an analytical model of the eddy current braking torque considering magnetic flux leakage and end effect is established. The power generation and braking performance of the SLB-EMR are predicted by the finite element analysis (FEA). We carried out tests for the eddy current braking torque, the heat-fade of braking torque, the no-load loss torque, and natural characteristics of the SLB-EMR respectively. The test results showed that the eddy current braking torque reached 2592 N·m at 1000 r/min. The braking torque declined by 15.5 % after the braking 12 min continuously. The analytical model of eddy current braking torque, and FEA model of the generator and eddy current brake were verified by the test. Compared with the ECR, the SLB-EMR had no-power consumption and low head-fade. © 2019, KSAE.","Eddy current braking; Liquid-cooled; Magnetic equivalent circuit (MEC); Self-excited","Analytical models; Eddy currents; Electric power utilization; Equivalent circuits; Liquids; Magnetic circuits; Magnetic leakage; Torque; Eddy current retarder; Electromagnetic retarder; Liquid cooled; Magnetic equivalent circuit method; Magnetic equivalent circuits; Magnetic flux leakage; Performance analysis; Self - excited; Braking performance",,,,,"National Natural Science Foundation of China, NSFC: 51741701, 51777003; Natural Science Foundation of Beijing Municipality: 3182007","The authors acknowledge the financial support from the National Natural Science Foundation of China under Project 51777003, the National Natural Science Foundation of China under Project 51741701 and Beijing Natural Science Foundation under Project 3182007.",,,,,,,,,,"Anwar, S., A parametric model of an eddy current electric machine for automotive braking applications (2004) IEEE Trans.

The generalized and efficient method proposed in this paper can be used to study the dynamics of complicated cracked structures without much modification. First, a three-dimensional finite element model of the cracked rotor-bearing system is established in the rotating frame and a general contact model for modeling the breathing crack is proposed. A component mode synthesis is used to form a reduced-order model. Then, a procedure combining multi-harmonic balance method with arc-length method is used to search the response solution. To accelerate the calculation, the analytical formulations for calculating the tangent stiffness matrix are used. Finally, the gravity induced response and breathing mechanism of a cracked rotor-bearing system are obtained. Interesting result is that the rotational speed and the crack depth will influence the breathing mechanism even if the load remains unchanged. © IMechE 2019.","alternating frequency/time technique; arc-length method;

An important characteristic of bridges highly affecting their behavior is the skew angle. In this paper, a sensitivity analysis is performed to identify the effects of skew angle on train-track interaction for single- and double-sided crossings of a high-speed train. Comprehensive three-dimensional finite element models of the bridge and vehicle are developed, which are then calibrated using dynamic field test results. Effects of skew angle on shape modes and modal frequencies, acceleration values, and bridge displacement in various crossing speeds are studied. The results showed that if the bridge skew angle is more than 15°, it will affect the modal shape and frequency of the bridge. When the skew angle is less than 15°, the results of the bridge displacement are similar to those of the bridge with skew angle of zero. However, with the increase of the skew angle, the deformation value of the bridge decreases and the speed corresponding to the maximum displacement value also varies. Finally, the results of acceleration due to the speed and skew angle of the bridge are not the same in one-way and two-way passing states. © 2019, Budapest University of Technology and Economics.

In order to investigate the influence of a partial arc on electric field distribution along the catenary insulator string, a three-dimensional model of the cap-pin insulator string with partial arc was established in this paper. The electric field distribution along the insulator string when the arc extended on the insulator surface and bridged sheds was investigated based on the electric field analysis using the finite element method. The results showed that the occurrence of a partial arc caused obvious distortion of the electric field, which was a two-dimensional axis symmetrical field before arcing to a three-dimensional field. In the case of arc extension, the sudden rise of field intensity was mostly at the rib and the shed edge, which had the local maximum field intensity. The rib and the shed edge played a certain hindrance role in the extension of the arc. The main reason for promoting the development of the arc can be attributed to thermal ionization. In the case of arc bridge sheds, the highest field intensity appeared at the edge of the last bridged shed. As the number of sheds arc-bridged increased, the maximum field intensity also increased. As the arc length increased, the electric field intensity of the arc head also increased, which resulted in an accelerated arc development. The main factor to promote the development of the arc can be attributed to electrical breakdown. The measures to hinder the rapid development of partial arcs were proposed. © 2019 by the authors.","Electric field distribution; Electrified railway catenary; Finite element method; Insulator string; Partial arc","Electric current collection; Electric fields; Overhead lines; Railings; Railroads; Electric field analysis; Electric field distributions; Electric field intensities; Electrified railways; Insulator string; Maximum field intensity; Partial arcs; Three-dimensional model; Finite element method",,,,,"National Natural Science Foundation of China, NSFC: 51567014, 51767014, 51867013","Funding: This work was financially supported by the Natural Science Foundation of China (51567014; 51767014; 51867013).",,,,,,,,,,"(2014) The Technology of High-Speed Railway Catenary, pp. 1-6. , China Railway Corporation.

This paper presents a Two-Stage-Model for determining the fatigue life of steel structures. The model follows the distinction between crack initiation and crack propagation according to the phenomenological background. The first stage uses the local strain-life approach to predict the number of cycles for crack initiation Ni considering the cyclic material behaviour as well as the load-time history. The second stage calculates the crack propagation based on a linear-elastic fracture mechanics approach. Using X-FEM in combination with cyclic loading, an arbitrary, solution-dependent crack path is achieved to determine the number of cycles for propagation Np. The Two-Stage-Model was applied to butt welds to determine their total fatigue life Nf in terms of a proof-of-concept study. The study investigated the ability of the model to consider the influence of the weld geometry, i.e. plate thickness and weld imperfections (excess and vertical offset). The results are presented by means of S-N curves for initiation life, propagation life and total fatigue life. A comparison with experimental results provided in the literature shows that the Two-Stage-Model can reflect the weld quality of butt welds in terms of fatigue life. © 2019 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co.

To reduce the structural vibration response of lashing bridges, a structural improvement method was proposed based on the results of optimization. The adoption of design specifications, expertise and other knowledge accumulated in design have been ignored in the development of structure design and optimization. To face the increasingly fierce competition in the marine market, the optimal solution is establishing a knowledge base containing expertise, design specification and successful design cases. In addition, the advanced techniques for design and optimization shall be incorporated with Knowledge-Based Engineering to automate new designs and optimizations. Furthermore, finite element method is employed to carry out the strength analysis. Lightweight design and vibration damping design of the lashing bridge are deemed as two critical issues having nagged designers. The Knowledge-Based Engineering–based design and optimization approach not only ensure the performance of the lashing bridge structure to be reasonable but also minimize the weight target and evidently improves the design quality and efficiency. The functionally graded thickness structure is applied to the improved scheme, which not only makes the design of the lashing bridge structure more reasonable but also reduces the vibration response of the structure. © IMechE 2018.","functionally graded thickness; Knowledge-Based Engineering; lashing bridge design; optimization; structures","Fuel tanks; Knowledge based systems; Optimization; Shape optimization; Specifications; Structural dynamics; Structural optimization; Structure (composition); Bridge design; Design and optimization; Design specification; Functionally graded; Knowledge-based engineering; Structural improvements; Structural vibrations; Vibration damping designs; Bridges",,,,,"201335; Ministry of Industry and Information Technology of the People's Republic of China, MIIT","The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This present paper is supported by both the project of High-tech Ship Research Projects Sponsored by MIIT (NO [2016] and The Chinese Government Key Research Project KSHIP-II project (Knowledge-based Ship Design Hyper-Integrated Platform) no. 201335.",,,,,,,,,,"Wolf, V., Darie, I., Rathjed, H., Rule development for container stowage on deck, 1, pp. 715-722. , Proceedings of the 3rd international conference on marine structures, Hamburg, 28–30 March 2011, London, Taylor & Francis Group, In; Kirkayak, L., Suzuki, K., Numerical analysis of container stacks dynamics, 3, pp. 205-208. , Proceedings of the Third PAAMES and AMEC, Chiba, Japan, 20–22 October 2008, Japan, JASNAOE, In; Suzuki, K., Kirkayak, L., Sueoka, H., Model test of container lashing dynamic behavior, 8, pp. 465-466. , Proceedings of the conference of the Japan Society of Naval Architects and Ocean Engineers, 1–2 September 2009, Japan, JASNAOE, In; Kirkayak, L., Suzuki, K., Sueoka, H., Dynamic simulation of container lashing behavior, 8, pp. 467-468. , Proceedings of the conference of the Japan Society of Naval Architects and Ocean Engineers, 1–2 September 2009, Japan, JASNAOE, In; Aguiar de Souza, V., Kirkayak, L., Suzuki, K., Experimental and numerical analysis of container stack dynamics using a scaled model test (2012) Ocean Eng, 39, pp. 24-42; Zhou, X.H., Qiu, Y.J., Hua, G.R., A feasible approach to the integration of CAD and CAPP (2007) Comput Aided Design, 39, pp. 324-338; Sanya, I.O., Shehab, E.M., An ontology framework for developing platform-independent knowledge-based engineering systems in the aerospace industry (2014) Int J Prod Res, 52, pp. 6192-6215; Kulon, J., Mynors, D.J., Broomhead, P., A knowledge-based engineering design tool for metal forging (2006) J Mater Process Tech, 177, pp. 331-335; Van der Velden, C., Bil, C., Xu, X., Adaptable methodology for automation application development (2012) Adv Eng Inform, 26, pp. 231-250; Amadori, K., Tarkian, M., Ölvander, J., Flexible and robust CAD models for design automation (2012) Adv Eng Inform, 26, pp. 180-195; Baxter, D., Gao, J., Case, K., An engineering design knowledge reuse methodology using process modelling (2007) Res Eng Des, 18, pp. 37-48; Verhagen, W.J.C., Bermell-Garcia, P., van Dijk, R.E.C., A critical review of knowledge-based engineering: an identification of research challenges (2012) Adv Eng Inform, 26, pp. 5-15; La Rocca, G., Knowledge based engineering: between AI and CAD.

For this purpose, the Oujiang River North Estuary Bridge which is a three-tower four-span suspension bridge with two main spans of 800m under construction in China is taken as an example in this study. This will be the first three-tower suspension bridge with steel truss girders in the world. The mechanical performance study and parametric analysis are conducted based on a validated three-dimensional spatial truss finite element model established for the Oujiang River North Estuary Bridge using MIDAS Civil. It is found that a relatively small side-main span ratio seems to be quite appropriate from the perspective of mechanical performance. And decreasing the sag-to-span ratio is an effective way to reduce the horizontal force subjected to the midtower and improve the antiskid safety of the main cable, while the vertical stiffness of the bridge will be reduced. However, the girder stiffness is shown to be of minimal significance on the mechanical performance. The findings from this paper can be used for design of three-tower suspension bridges with steel truss girders.

The modeling is conducted by using the finite element method to obtain the electrical potential distribution and sensitivity map with the proposed capacitance sensor array. An experimental test setup, which is composed of an eight-electrode capacitance sensor array and a commercialized capacitance bridge instrument for measurement, is developed. Experiments regarding different leakage scenarios are carried out by using the test setup. Preliminary results standing for different water leakage cases, which are based on the experimental data obtained from the test setup, are presented and depicted as images reconstructed by using different algorithms including the linear back projection (LBP), the projected Landweber iteration, and the total variation regularization. These results demonstrate that the proposed capacitance sensor array is feasible and has a great potential for imaging of water leakage inside insulating slabs with porous cells. A cost-effective capacitance measurement circuit for practical applications is also proposed and simulated. © 2019 by the authors.

The screed machine and the fresh concrete loads acting on the overhang portion of the deck slab are very significant since they cause unbalanced eccentric loads, resulting in deflection of the overhang and rotation of the exterior girders. Moreover, as the concrete has not hardened yet, the deck slab formwork deflects, causing a non-uniform slab thickness, transversely. Other issues, such as a reduction in steel rebar cover, poor rideability, and local buckling in the girders, can occur from this. Many temporary bracing systems are currently used to prevent the rotation of the exterior girder due to construction loads, such as transverse and diagonal ties, timber blocks, and temporary cross bracing at the exterior panels. However, recent studies show that these bracing systems are not effective enough, and more efficient methods will be needed to solve this problem. The goal of this research is to find the most significant geometrical parameters that affect the rotation of the exterior girders under construction loads. Six parameters were considered in this study: the girder's section properties, the unbraced length, the overhang width, the number of girders, the girder spacing and the diaphragm's section properties. SAP2000 software was used to develop the Finite Element models to carry out the parametric study. The rotation of the exterior girders was recorded at the middle of the span at three locations (the top flange, the center of the web and the bottom flange). The results showed that the most significant variables to the rotation of the exterior girder were the girder's section properties, the unbraced length, and the overhang width. Based on these three parameters a regression model is developed to predict the rotation value with an average error of 9.7%. © 2019 Elsevier Ltd","Construction loads; Deck overhang construction; Design of Experiments (DOE); Exterior girder rotation; Finite Element Modeling; Linear regression; Parametric study","Bridge decks; Concretes; Design of experiments; Finite element method; Flanges; Geometry; Linear regression; Regression analysis; Rotation; Bridge constructions; Construction loads; Future performance; Girder rotations; Parametric study; Regression model; Significant variables; Temporary bracings; Beams and girders; bridge construction; concrete; design; finite element method; geometry; loading; parameterization; regression analysis; software",,,,,"U.S. Department of Transportation, DOT; Illinois Department of Transportation, IDOT","This publication is based on the results of ICT-R27-179, Effectiveness of Exterior Beam Rotation Prevention Systems for Bridge Deck Construction - Phase II.

This paper proposed a new method of modeling spatially varying ground motion due to ice-seawater layer. The reflection function was derived to evaluate the effect of ice-seawater layer on earthquake ground motion. Moreover, the coherence function and site transfer function were used to calculate the loss of spatial coherent and the corresponding local effects, respectively. Furthermore, the effects of water saturation on ground motion was considered. Taking the above factors into consideration, the spatial variance of seismic ground motions in an area with an ice-seawater interface was synthesized. The ground motion was assumed to consist of SH and P-SV waves, which included horizontal out-of-plane SH wave, horizontal in-plane P-SV waves and vertical in-plane P-SV waves. By comparing simulated ground motions with different site conditions, we observed that the vertical in-plane motion at the seafloor was noticeably attenuated when an ice-seawater interface was present. At the same time, the soil layer greatly amplified the acceleration of out-of-plane and in-plane ground motions. In order to verify the ability of the above method for synthesizing seismic time history, a three-dimensional seismic analysis of a large span cable-stayed bridge was conducted. Three of such case studies were used to investigate the effect of the ice-seawater interface on the bridge. Analysis of the displacement and bending moment of the bridge deck and tower demonstrated that the ice-seawater interface had a great effect on the seismic response of the cable-stayed bridge. In particular, the maximum vertical deck displacement with the ice-seawater interface present was 74% of the case in which the interface was absent. Likewise, the maximum longitudinal displacement of the bridge tower with the interface present was 70% of the case in which the interface was absent. © 2019 Elsevier Ltd","Cable-stayed bridge; Finite element analysis;

Three different methods are investigated in this paper, first method is the conventional method based on Asymmetrical H-Bridge converter providing fixed voltage in both magnetization and demagnetization instances. Second method is when demagnetization voltage is boosted compared to magnetization voltage but conventional control algorithm is used and it is shown that in this condition, the vibration intensity is too high. Third method uses a control algorithm to impose the boosted demagnetization voltage in a way that reduces vibrartion intensity of stator's frame. For all three methods firstly an electromagnetic finite element analysis is used to obtain radial forces and these forces are passed through motor's vibration transfer function and vibration waveforms are obtained. Finally a comparison between vibration response of these three methods is done. © 2019 IEEE.","finite element analysis; switched reluctance motor; Vibration and acoustic noise; vibration transfer function","Acoustic noise; Bridge circuits; Demagnetization; Finite element method; Magnetization; Power electronics; Reluctance motors; Transfer functions; Asymmetrical H-bridge converter; Conventional control; Conventional methods; Demagnetization voltage; Switched Reluctance Motor; Vibration reductions; Vibration transfer; Vibration waveforms; Vibration analysis",,,,,,,,,,,,,,,,"Krishnan, R., (2001) Switched Reluctance Motor Drives: Modeling, Simulation, Analysis, Design, and Applications, pp. 6-9. , CRC press, H.

To investigate the dynamic characteristics of a long-span concrete-filled steel tubular arch bridge, we chose a global navigation satellite systems-real-time kinematic (GNSS-RTK) to monitor its vibration responses under ambient excitation. A novel approach, the use of complete ensemble empirical mode decomposition with adaptive noise combined with wavelet packet (CEEMDAN-WP) is proposed in this study to increase the accuracy of the signal collected by GNSS-RTK. Fast Fourier transform (FFT) and random decrement technique (RDT) were adopted to calculate structural modal parameters. To verify the combined denoising and modal parameter identification methods proposed in this paper, we established the structural finite element model (FEM) for comparison. Through simulation and comparison, we were able to draw the following conclusions. (1) GNSS-RTK can be used to monitor the dynamic response of long-span bridges under ambient excitation; (2) the CEEMDAN-WP is an efficient method used for the noise reduction of GNSS-RTK signals; (3) after signal filtering and noise reduction, structural modal parameters are successfully derived through RDT and illustrated graphically; and (4) the first-order natural frequency identified by field measurement is slightly higher than the FEM in this work, which may have been caused by bridge damage or the inadequate accuracy of the finite element model. © 2019 by the authors.","CEEMDAN-WP; Dynamic deformation monitoring; Finite element simulation; GNSS-RTK; Long-span arch bridge; RDT",,,,,,"Tianjin University, TU","This research received no external funding.

New subroutines have been added to ANSYS via its UPF customization tool to implement viscoelastoplastic constitutive equations with cracking capability to model concrete’s structural behavior. This numerical implementation allowed the use of three-dimensional twenty-node quadratic elements (SOLID186) with the Element-Embedded Rebar model option (REINF264), conducting to a fast and efficient solution. These advantages are of fundamental importance when large structures, such as bridges, are modeled, since an increasing number of finite elements is demanded. After validating the subroutines, the bridge located in Rio de Janeiro, Brazil, and known as “Ponte do Saber” (Bridge of Knowledge, in Portuguese), has been numerically modeled, simulating each of the constructive phases of the bridge. Additionally, the data obtained numerically is compared with the field data collected from monitoring conducted during the construction of the bridge, showing good agreement.

However, this technique leads to a delami-nation problem, which is a failure mode that occurs between the FRP patch and the retrofitted structure and is caused by the interfacial stress concentration in the adhesive layer, thereby reducing the effectiveness of this reinforcement technique. Thus, the objective of this research is to investigate the taper effect of multilayer FRP patch on the reduction of the interfacial stresses, including fiber orientation and shear-lag effect, while thermo-mechanical loads are applied. An analytical model is developed to predict the interfacial stresses in the adhe-sively patched structures with FRP. A numerical simulation using finite element method is also employed to validate the results from the analytical analysis. Finally, a parametric study is carried out in order to determine the influence of each parameter and to determine the optimal configurations.

A CFRP drive shaft of a motor spindle and a CFRP lock nut are taken as examples for such parts and are further investigated. As CFRP drive shafts are usually manufactured by filament winding and reworked by grinding, it is consistent to manufacture the thread in the shaft by grinding, too. For the CFRP lock nut two concepts are developed that do not require grinding or reworking. They are simply manufactured by compression moulding. Both concepts are optimized for high strength at low weight. Specimens of both optimized lock nut concepts and the corresponding shafts are manufactured and tested regarding their eligibility to fix bearings on drive shafts. Subsequent tests proove the latter: At a weight of 48 grams the lock nuts could bear a load of 100 kN without damage. © 2018 Elsevier Ltd","C. Finite element analysis (FEA); D. Mechanical testing; E.

This paper deals with experimental investigations into out-of-plane ultimate resistance of fixed circular parallel twin-arch under uniform radial load. Seven parallel twin-arch consisting of two steel tubular arch ribs connected by lateral braces are tested under symmetric radial loading. A loading frame comprising a reaction beam, sliding supports and distribution beams is used to apply five-point radial loads over the full span of the arch ribs. Initial out-of-plane imperfections are generated by a push rod before loading. The test results show that all of the specimens fail in an out-of-plane symmetric C-shaped buckling mode, and the lateral displacements are much larger than the vertical displacements. It is also found that the stiffness of the lateral braces have great effects on the ultimate resistance of the parallel twin-arch. The ultimate resistance increases as the cross-section diameter of lateral braces increase. A finite element model is also developed. Comparisons of the FE results for the out-of-plane elasto-plastic behaviour of parallel twin-arch with the experimental ones indicate that the finite element model can predict the elasto-plastic out-of-plane buckling response of parallel twin-arch very well. © 2018 Elsevier Ltd","Experimental investigation; Finite element analysis; Out-of-plane buckling; Parallel twin-arch; Ultimate resistance","Arches; Elastoplasticity; Finite element method; Elasto-plastic behaviours; Engineering practices; Experimental investigations; Lateral displacements; Numerical investigations; Out of plane buckling; Ultimate resistance; Vertical displacements; Arch bridges",,,,,"National Natural Science Foundation of China, NSFC: 51678169; China Scholarship Council, CSC: 201708440154; Pearl River S and T Nova Program of Guangzhou: 201605061406434; Science and Technology Planning Project of Guangdong Province: 2016B050501004","This work has been supported by the National Natural Science Foundation of China (Grant No. 51678169 ), the Pearl River S&T Nova Program of Guangzhou (Grant No. 201605061406434 ) and the China Scholarship Council (Grant No. 201708440154 ) awarded to the first author, and the Technology Planning Project of Guangdong Province (Grant No. 2016B050501004 ) awarded to the second author.",,,,,,,,,,"(2011), JGJ/T 249-2011.

Based on the hyperbolic sinusoidal equation that included an Arrhenius term, a constitutive model of flow stress was established for the unidirectional solidification sheet of AZ31 magnesium alloy. Furthermore, discretized by the cellular automata (CA) method, a real-Time nucleation equation coupled flow stress was developed for the numerical simulation of the microstructural evolution during DRX. The stress and strain results of finite element analysis were inducted to CA simulation to bridge the macroscopic rolling process analysis with the microscopic DRX activities. Considering that the nucleation of recrystallization may occur at the grain and R-grain boundary, the DRX processes under different deformation conditions were simulated. The evolution of microstructure, percentages of DRX, and sizes of recrystallization grains were discussed in detail. Results of DRX simulation were compared with those from electron backscatter diffraction analysis, and the simulated microstructure was in good agreement with the actual pattern obtained using experiment analysis. The simulation technique provides a flexible way for predicting the morphological variations of DRX microstructure accompanied with plastic deformation on a hot-rolled sheet. © 2019 Ming Chen et al.",,"Cellular automata;

The long-term structural health monitoring responses are collected from the instrumented gusset-less connection at the Memorial Bridge to determine the nominal fatigue response using the collected strain responses. In addition, a global multi-scale finite element model of the bridge is created to effectively model the structural components of the bridge. A local sub-structure finite element model of the connection is created to determine the stress concentration factors that are applied for the hot-spot fatigue assessment method. The acquired stress concentration factors under the static and dynamic load test are applied for hot-spot fatigue assessment of the gusset-less connection. © 2019 - IOS Press and the authors.

For this purpose, a series of numerical simulations were carried out. First of all, the tsunami-induced flow speed, direction and tsunami height were determined by conducting a two-dimensional (2D) tsunami propagation analysis in a large area, and then these parameters obtained from tsunami propagation analysis were employed in a detailed three-dimensional (3D) fluid analysis to obtain tsunami-induced wave impact force. Furthermore, a fiber model, which is commonly used in the seismic analysis of steel bridge structures, was adopted considering material and geometric nonlinearity. The residual stresses induced by the earthquake were applied into the numerical model during the following finite element analysis as the initial stress state, in which the acquired tsunami forces were input to a whole bridge system. Based on the analytical results, it can be seen that the foundation sliding was not observed although the caisson foundation came floating slightly, and the damage arising during the earthquake did not expand when the tsunami-induced wave impact is applied to the steel bridge. It is concluded that the influence of tsunami-induced wave force is relatively small for such steel bridge with large caisson foundations. Besides, a numerical procedure is proposed for quantitatively estimating the accumulative damage induced by the earthquake and the tsunami in the whole bridge system with large caisson foundations.

The results show that supporting conditions and chambers have a significant impact on the shear-increased coefficient η, and end diaphragm must be set up in the 3D finite element model when calculating η. Nonlinear analysis shows that in the elastic phase, the shear-increased coefficient η basically does not change, but in the cracking stage, the coefficient η of each web changes with the degree of web cracking, and side-webs (S-Webs) reach the ultimate load first. The variation of the web thickness hardly affects the distribution of the shear force, so the method to adjust the web thickness of S-Web was proposed according to the result of shear-increased coefficient η to improve the shear resistance of the box girder. © 2019 Xingwei Xue et al.",,"Beams and girders;

The experimental results are linked with FEA predictions to explain failure and find the optimum design. The test samples used were three unit fixed partial dentures obtained by CAD/CAM using as starting point a clinical case. Design improvement attempt was to increase connector cross-section size and modify its shape. Four samples with circular and elliptical connector cross-sections and 5mm2 and 9mm2 area were tested in flexure. The models created for CAM were used to perform FEA and find the stress distribution, pinpoint the stress concentrators and link the results to experimental failure modes. The results showed that connector design plays an important role in restoration success and increasing connector cross-section area the stress is distributed in a uniform manner. It was concluded that increasing connector cross-section area and using a wider shape (ellipse) strongly decreases failure probability. © 2019 SYSCOM 18 S.R.L..

In addition, conventional design office load rating techniques cannot be used for bridges without structural plans, which indicates the need for a more advanced load rating procedure. This paper presents a methodology to compute the live load-carrying capacity of reinforced concrete T-beam bridges, which can be applied for bridges with structural plans or with missing or limited design information. The method involves modal identification of bridge using ambient vibrations and finite element model updating using vibration characteristics for capacity estimation. A simply supported T-beam bridge located in Virginia is selected for field-testing to verify the proposed method. The bridge is composed of five spans of the same length, 12.95, m for each, with a total length of 65.4, m and a width of 8.864, m. A total of nine accelerometers are installed to bridge to collect acceleration data for 15, min at a sampling rate of 500, Hz. The modal properties of the bridge are determined using enhanced frequency domain decomposition technique. The initial finite element model of the bridge is updated such that the modal properties of the bridge match the field measured parameters. The load effects and capacity of the bridge are determined and used to calculate the load rating factor. The rating factors obtained from the proposed method and traditional design office load rating procedures are compared. The results indicate that the proposed method can reveal the reserve capacity of bridges. © The Society for Experimental Mechanics, Inc 2019.","Dynamic testing; Load rating; Modal analysis; Vibrations","Bridges; Concrete beams and girders; Concrete construction; Concrete testing; Domain decomposition methods; Dynamic analysis; Frequency domain analysis; Modal analysis; Reinforced concrete; Structural dynamics; Vibration analysis; Ambient Vibration Testing; Dynamic testing; Enhanced frequency domain decompositions; Finite-element model updating; Load ratings; Modal identification; Vibration characteristics; Vibrations; Finite element method",,,,,"Virginia Department of Transportation, VDOT","Acknowledgements This material is based upon the work supported by the Virginia Department of Transportation.

A preliminary, simple and workable procedure of bridge damage detection is required to minimize maintenance costs. In the past, frequency is one of the most common indicators to detect damage occurrence. Recent research found that using frequency as a health indicator still has room to improve. Alternatively, dynamic displacement is used as an indicator in the current study. These dynamic displacements are reconstructed based on measured acceleration records from micro electro mechanical system (MEMS) sensors. The Newmark-beta method with Windows is proposed to acquire the reconstructed displacements of considered bridges. To demonstrate the accuracy and applicability of the proposed approach, three different experiments are carried out; (i) A small scale bridge with the implementation of MEMS acceleration sensors; (ii) a numerical complex finite element method (FEM) bridge model; (iii) an actual bridge with the implementation of MEMS acceleration sensors and narrow bandwidth Internet of things (NB-IoT) technology. The first experiment shows that the proposed method can successfully identify the difference between damaged/undamaged bridges and determine damage location. The second experiment indicates that the proposed method is able to identify the difference between stiffened/unstiffened bridges. The last experiment shows the applicability of the proposed method on an actual bridge health monitoring project. © 2020 by the authors.

However, there are few methods to determine the reasonable target reliability index for long-span cable-stayed bridges. In this work, an original approach to solve this problem is developed. In this approach, a concept of optimal structural parameter ratio is presented from the perspective of cost-benefit. Determination of structural target reliability index should meet the requirements of safety and economy. This approach includes two parts. First, based on the statistical parameters of load and resistance of the cable-stayed bridge's main girder and the most unfavourable bending moments obtained by finite element analysis, the structural reliability index was calculated by the JC method. Second, the reliability indexes with different structural parameter ratios were calculated, and the relational expression between the reliability index and structural parameter ratio was obtained by data fitting. Then the optimal structural parameter ratio was calculated from the perspective of cost-benefit. Finally, by substituting the optimal structural parameter ratio into the relational expression between the reliability index and structural parameter ratio, the optimal reliability index can be obtained. The optimal reliability index corresponding to the optimal structural parameter ratio can be regarded as the target reliability index. © 2020 Institution of Structural Engineers","Cable-stayed bridge; Cost benefit analysis; Main girder; Optimal structural parameter ratio; Target reliability index",,,,,,"19B020; National Natural Science Foundation of China, NSFC: 51678067, 51808054; Systematic Project of Guangxi Key Laboratory of Disaster Prevention and Structural Safety: 2016ZDK014","This work was jointly supported by the Research Project of the Educational Commission of Hunan Province (grant NO. 19B020), the National Natural Science Foundation of China (grant NO. 51678067 , 51808054 ) and the Systematic Project of Guangxi Key Laboratory of Disaster Prevention and Structural Safety (grant NO. 2016ZDK014).",,,,,,,,,,"Zhang, Z., Zhou, M., Hu, C., Liu, M., Research on reasonable value of target reliability index for steel main girder of cable-stayed bridge considering durability (2019) Struct Infrastruct Eng, 15 (10), pp. 1382-1391; Li, G., Cheng, G., Optimal decision for the target value of performance-based structural system reliability (2001) Struct Multidiscip Optim, 22 (4), pp. 261-267; Bairán, J.-M., Casas, J.R., Safety factor calibration for a new model of shear strength of reinforced concrete building beams and slabs (2018) Eng Struct, 172, pp. 293-303; Qin, Q., Zhao, G., Calibration of reliability index of RC beams for serviceability limit state of maximum crack width (2002) Reliab Eng Syst Saf, 75 (3), pp. 359-366; Huang, X., Zhou, Y., Xing, F., Wu, Y., Han, N., Reliability-based design of FRP flexural strengthened reinforced concrete beams: Guidelines assessment and calibration (2019) Eng Struct, 22, pp. 109-953; Ching, J., Phoon, K.-K., A quantile-based approach for calibrating reliability-based partial factors (2011) Struct Saf, 33 (4-5), pp. 275-285; Ching, J., Phoon, K.-K., Quantile value method versus design value method for calibration of reliability-based geotechnical codes (2013) Struct Saf, 44, pp. 47-58; Hong, J., Shen, G.Q., Li, Z., Zhang, B., Zhang, W., Barriers to promoting prefabricated construction in China: A cost–benefit analysis (2018) J Cleaner Prod, 172, pp. 649-660; Dong, Y., Frangopol, D.M., Probabilistic life-cycle cost-benefit analysis of portfolios of buildings under flood hazard (2017) Eng Struct, 142, pp. 290-299; Liu, S.C., Neghabat, F., A Cost Optimization Model for Seismic Design of Structures (1972) Bell Labs Tech J, 51 (10), pp. 2209-2225; Liu, S.C., Dougherty, M.R., Neghabat, F., Optimal Aseismic Design of Building and Equipment (1976) J Eng Mech Div, 102 (3), pp. 395-414; Ang, A.H.-S., Leon, D.D., Determination of optimal target reliabilities for design and upgrading of structures (1997) Struct Saf, 19 (1), pp. 91-103; Cho, H.N., Ang, A.H.S., Lim, J.K., Shim, S.T., Determination of cost-effective optimal target reliability for seismic design and upgrading of long span PC bridges (2000) ASCE Specialty Conference on Probabilistic and Structural Reliability; Zhang, Z., Liu, X., Zhang, Y., Zhou, M., Chen, J., Time interval of multiple crossings of the Wiener process and a fixed threshold in engineering (2020) Mech Syst Sig Process, 135, p. 106389; Wang, Y., Li, Z., Li, A., Combined use of SHMS and finite element strain data for assessing the fatigue reliability index of girder components in long-span cable-stayed bridge (2010) Theor Appl Fract Mech, 54 (2), pp. 127-136; Truong, V.-H., Kim, S.-E., An efficient method of system reliability analysis of steel cable-stayed bridges (2017) Adv Eng Softw, 114, pp. 295-311; Prenninger, P.H.W., Matsumoto, M., Shiraishi, N., Izumi, C., Tsukiyama, Y., Reliability of bridge structures under wind loading: Consideration of uncertainties of wind load parameters (1990) J Wind Eng Ind Aerodyn, 33 (1-2), pp. 385-394; Ge, Y., Xiang, H., Tanaka, H., Application of a reliability analysis model to bridge flutter under extreme winds (2000) J Wind Eng Ind Aerodyn, 86 (2-3), pp. 155-167; Ministry of Transport of P.

The stiffness matrix, damping matrix, mass matrix, wheel-rail contact force matrix and the equations of motion of the coupled system considering slip and shear-lag are derived based on energy theory. In addition, a solver for dynamic analysis of the coupled system considering slip and shear-lag is compiled by using the Newmark-β method. To verify the rationality of the dynamic analysis model, field-test data for this type of coupled system from literature is compared with the data calculated by the improved model, and good agreement is found. The influence of slip and shear-lag on the dynamic response of the coupled system is studied in detail through a case study. The analysis proves that these factors (slip and shear-lag) substantially affect the dynamic response of the coupled system.

The structure of the PTFTs was a simple circular plate of Pb(Zr,Ti)O3 (PZT) thin film on a Si layer with ring-dot top electrodes and it was suspended by four pantograph-shaped bridges. We estimated the performance of the PTFTs by finite-element method simulations. In accordance with the FEM simulation model, PZT thin films were deposited on silicon-on-insulator substrates and microfabricated into PTFTs with ring-dot structures. From the produced devices, an admittance circle measurement was carried out, enabling us to predict performance. The actual output characteristics of the PTFTs were clearly observed at a resonance frequency (f r) of 4.57 MHz. At this point, a voltage gain of 0.22 and a power density of 704 W cm-3 were measured, under a load resistance (R L) of 22 Ω. © 2020 The Japan Society of Applied Physics.",,"Finite element method; Piezoelectricity; Silicon on insulator technology; Structural design; Circular plates; Finite element method simulation; Load resistances; Output characteristics; Piezoelectric pzt thin films; Piezoelectric thin films; Resonance frequencies; Silicon-on-insulator substrates; Thin films",,,,,,,,,,,,,,,,"Priya, S., (2006) IEEE Trans.

Especially for surface-mounted permanent magnet synchronous motor (SPMSM) with similar number of poles and slots, because the zigzag leakage flux is big and varies with the relative positions between stator and rotor, selecting no-load leakage flux coefficient with experience may cause a big calculation error to electromagnetic parameters by equivalent magnetic circuit model. Finite-element method (FEM) can directly calculate the coefficient, but entire process is time-consuming. Focusing on this problem, an analytical model of no-load leakage flux coefficient is proposed including air-gap leakage flux model and zigzag leakage flux model. Then, an improved subdomain model for magnetic field calculation of SPMSM is established, and the air-gap magnetic flux density, inducing flux linkage and line no-load back electromotive force (EMF) are calculated considering no-load leakage flux. To verify the improved model, an external rotor type SPMSM with 20-poles and 24-slots for bridge crane is designed and manufactured. Finally, the validity of improved model is verified by experimental test. © 2020, The Korean Institute of Electrical Engineers.","Improved subdomain model; Leakage flux; Similar number of poles and slots; SPMSM","Electric motors; Loads (forces); Magnetic circuits; Magnetic fields; Permanent magnets; Air-gap magnetic flux densities; Back electromotive force; Electromagnetic parameters; Equivalent magnetic circuit model; Magnetic field calculations; Permanent magnet motor; Relative positions; Surfacemounted permanent magnet synchronous motors (SPMSM); Magnetic leakage",,,,,,,,,,,,,,,,"Wang, K., Gu, Z.Y., Zhu, Z.Q., Wu, Z.Z., Optimum injected harmonics into magnet shape in multiphase surface-mounted PM machine for maximum output torque (2017) IEEE Trans Magn, 64 (6), pp. 4434-4443; Nair, S.S., Wang, J.B., Chin, R., Chen, L., Sun, T.F., Analytical prediction of 3-D magnet eddy current losses in surface mounted PM machines accounting slotting effect (2017) IEEE Trans Energy Convers, 32 (12), pp. 414-423; Liu, Y., Zhu, Z.Q., Gan, C., Comparison of optimal slot/pole number combinations in fractional slot permanent magnet synchronous machines having similar slot and pole numbers (2019) IET J Eng, 2019 (17), pp. 4585-4589; Zhu, Z.C., Huang, Y.K., Dong, J.N., Investigation study of the influence of pole numbers on torque density and flux weakening ability of fractional slot concentrated winding wheel-hub machines (2019) IEEE Trans Access, 7 (17), pp. 1-6; Toudji, M., Parent, G., Duchesne, S., Determination of winding lumped parameter equivalent circuit by means of finite element method (2017) IEEE Trans Magn, 53 (6), pp. 1-4; Chen, Q., Liu, G.H., Zhao, W.X., Shao, M.M., Nonlinear adaptive lumped parameter magnetic circuit analysis for spoke-type fault-tolerant permanent-magnet motors (2013) IEEE Trans Magn, 49 (9), pp. 5150-5157; Wu, L.J., Zhu, Z.Q., Staton, D., Comparison of analytical models of cogging torque in surface mounted PM machines (2012) IEEE Trans Ind Electron, 59 (6), pp. 2414-2425; Golovanov, D., Gerada, C., An analytical subdomain model for dual-rotor permanent magnet motor with halbach array (2019) IEEE Trans Magn, 55 (12), pp. 1-4; Wu, L.J., Zhu, Z.Q., Staton, D.A., Comparison of analytical models of cogging torque in surface-mounted PM machines (2012) IEEE Trans Industr Electron, 59 (6), pp. 2414-2425; Liang, P.X., Chai, F., Li, Y., Pei, Y.L., Analytical prediction of magnetic field distribution in spoke-type permanent-magnet synchronous machines accounting for bridge saturation and magnet shape (2017) IEEE Trans Industr Electron, 64 (5), pp. 3479-3489; Boughrara, K., Lubin, T., Ibtiouen, R., General subdomain model for predicting magnetic field in internal and external rotor multiphase flux-switching ma-chines topologies (2013) IEEE Trans Magn, 498 (10), pp. 5310-5325; Fei, W., Luk, P.C.K., A generic approach to reduction of magnet motive force harmonics in permanent-magnet machines with concentrated multiple three-phase windings (2014) IEEE Trans Ind Appl, 50 (11), pp. 1-4; Liang, P.X., Chai, F., Yu, Y.J., Analytical model of a spoke-type permanent magnet synchronous in-wheel motor with trapezoid magnet accounting for tooth saturation (2019) IEEE Trans Industr Electron, 66 (2), pp. 1162-1171; Wu, L.J., Zhu, Z.Q., Staton, D., Subdomain model for predicting armature reaction field of surface-mounted permanent-magnet machines accounting for tooth-tips (2011) IEEE Trans Magn, 47 (4), pp. 812-822; Dubas, F., Espanet, C., Analytical solution of the magnetic field in permanent-magnet motors taking into account slotting effect: No-load vector potential and flux density calculation (2009) IEEE Trans Magn, 45 (5), pp. 2097-2109; Lee, J.K., Jung, D.H., Lee, K.D., A study on analysis of synchronous reluctance motor considering axial flux leakage through end plate (2019) IEEE Trans Magn, 55 (6), pp. 1-4; Ye, X., Zheng, S., Zhang, Y., Modeling and optimization of IRTMB for high-speed motor considering magnetic flux leakage effect (2019) 2019 22Nd International Conference on Electrical Machines and Systems (ICEMS); Zheng, M., Zhu, Z.Q., Cai, S., Influence of stator and rotor pole number combinations on the electromagnetic performance of stator slot-opening PM hybrid-excited machine (2019) IEEE Trans Magn, 55 (5), pp. 1-10; Qu, R.H., Lipo, T.A., Analysis and modeling of air-gap and zigzag leakage fluxes in a surface-mounted permanent-magnet machine (2004) IEEE Trans Ind Appl, 40 (1), pp. 121-127","Yu, Z.; Economic and Technological Development Zone, No. 111, Shenliao West Road, China; email: 1534377454@qq.com",,,"Korean Institute of Electrical Engineers",,,,,19750102,,,,"English","J.

A three-dimensional finite element model of mandibular molar section of the bone to receive implants was constructed. Three implant-supported fixed partial dentures, with null, moderate and wide tilting, of 0°, 15° and 30° implant inclinations, respectively, were modeled. A mechanical load of 10 MPa was applied in coronal–apical direction on bridge framework at the regions of crowns positions. The finite element analysis was performed, and von Mises stress levels were calculated. Peak stress concentration in the cortical bone was observed mostly around the implant necks, in inter-implants line. There was favorable stress distribution during loading, with peak stress being 90.04 MPa for 0°, which decreased to 54.33 MPa for 15° and 46.36 MPa for 30° inclination. The supporting implants inclination in fixed partial denture plays an important role in stress distribution and may be helpful in preventing bone loss and implant failure. This phenomenon is likely to be more pronounced in bones of poor quality. Within the limitation of this study, it seems that the inclination of implants in fixed partial denture has a favorable effect on stress distribution pattern values around the supporting implants. © IMechE 2020.","bone; dental biomechanics; finite elements analysis; Implant inclination; stress","Bone; Stress analysis; Stress concentration; Thermoelectricity; Cortical bone; Distribution patterns; Finite-element study; Fixed partial dentures; Implant failures; Mechanical loads; Three dimensional finite element model; Von Mises stress; Finite element method; dental procedure; finite element analysis; fixed partial denture; mandible; mechanical stress; molar tooth; tooth implant; Dental Implants; Dental Stress Analysis; Denture, Partial, Fixed; Finite Element Analysis; Mandible; Molar; Stress, Mechanical",,"Dental Implants",,,"University of Jordan, UJ","This study was conducted during the sabbatical leave of Dr Hashem Alkhaldi from The University of Jordan in the academic year 2018/2019, and hosted by Al-Zaytoonah University of Jordan.

The characteristics of the failure on the bottom plate were analysed and three typical failure models are identified. The failure mechanism was investigated and verified using a proposed 3D nonlinear FE model. Retrofit methods are proposed and implemented for the damaged bridges. The measured stress response and calculated stress response from the proposed 3D finite element model are compared. Satisfactory results are observed between field measurements and numerical simulations. Parametric studies are performed using the developed model to investigate several important parameters for the bridge design and construction.

Such tools will aid system designers in the optimization of capacitor discharge circuit (CDC) or EFI bridge material properties. The analytical elements of the approach developed support the requirement for the consideration of mass ejection variation with respect to initial capacitor voltage. The numerical elements of the approach developed demonstrate that EFI design alteration to increase flyer mass is less effective in reducing ToAD than supply voltage modulation via the CDC. This finding is of particular relevance for in situ control of functional performance characteristics. This work goes on to demonstrate that such control is impracticable when using hexanitrostilbene, since the initial capacitor voltages necessary to yield appropriate ToAD for deflagration deliver insufficient energy to instigate a response from the EFI. © The Author(s) 2019.","Exploding foil initiator;

Four girders were fabricated using two types of concrete (compressive strengths: 50 MPa and 70 MPa) and tested under four-point bending until failure. The measured parameters included the deflection, the stress and strain in concrete and steel bars, and cracks in concrete. The measurement results were used to analyze the failure mode, load-bearing capacity, and deformability of each girder. A finite element model is established to simulate the flexural behaviors of the girders. The results show that the use of high-performance concrete and reasonable combination of prestressed tendons could improve the mechanical performance of the box girders, in terms of the crack resistance, load-carrying capacity, stress distribution, and ductility.

In this study, the main equations (including those for the induced electromotive force of the active coils and the total damping force of the damper) were derived through magnetic circuit analysis using the main parameters of the electromagnetic damper model. Characteristic tests were performed on electromagnetic damper prototypes to analyze the hysteretic dynamics and derive characteristics according to their structure and excitation conditions. On the basis of the results, we proposed a regenerative hybrid electrodynamic damper with an oxygen-free copper tube and teeth structure. Its physical and electromagnetic behaviors were examined through an electromagnetic analysis of the finite element model of the proposed damper. The results confirmed that attenuation occurred via strengthened magnetic flows, and the estimated power production is suitable for energy harvesting applications. Therefore, we confirmed the feasibility of constructing a system that can simultaneously perform cable attenuation and vibration monitoring using the proposed damper. © 2020 by the authors.","Electromagnetic damper; Electromagnetic finite element analysis; Hysteresis loop; Stay cable damping; Vibration monitoring",,,,,,"National Research Foundation of Korea, NRF; Ministry of Science and ICT, South Korea, MSIT: 2017R1A5A1014883, NRF-2019R1A2C2007835","Funding: This work was supported by the National Research Foundation of Korea (NRF) grant funded by the Korean government (MSIT) (No. 2017R1A5A1014883 and NRF-2019R1A2C2007835",,,,,,,,,,"Kim, S., Park, J., Kim, H.K., Damping Identification and Serviceability Assessment of a Cable-Stayed Bridge Based on Operational Monitoring Data (2017) J.

In the past, assessment models have mainly been developed from laboratory studies that simplified real-world conditions. Large-scale or full-scale field experiments are needed to validate more recent improved models. The goal of this study is to calibrate improved models using data obtained from a full-scale bridge deck slab shear test; the objective is to exploit and share our findings and to make recommendations for the planning, design, and implementation of such a complex experiment. Full-scale destructive tests of a 55-year-old reinforced concrete bridge deck slab on prestressed concrete girders were conducted to calibrate a model used to assess existing bridges. Concrete properties were also tested to evaluate the condition of the bridge. Results show that both the load-carrying capacity of the bridge deck slab and the strength of the concrete were much greater than were assumed in design. Finite-element analysis of the parameters governing loading positions and prestress in the girders showed that arch action and boundary condition simplification had important effects on shear distribution. © 2020 American Society of Civil Engineers.","Field destructive test; Full-scale bridge; RC bridge deck slab; Shear and punching","Arch bridges; Bridge decks; Concrete beams and girders; Concrete bridges; Concrete construction; Concrete slabs; Concrete testing; Load limits; Loads (forces); Prestressed concrete; Railroad bridges; Shear flow; Assessment models; Bridge deck slabs; Concrete properties; Destructive testing; Destructive tests; Full-scale field experiment; Laboratory studies; Shear distributions; Reinforced concrete",,,,,"Luther Theological University, LTU; Chalmers Tekniska Högskola; Lunds Universitet; Kungliga Tekniska Högskolan, KTH; Lunds Tekniska Högskola, Lunds universitet, LTH; Trafikverket","The authors would like to acknowledge financial support from The Swedish Transport Administration (Trafikverket).

A simple design methodology to include the Litz wire configuration in the optimisation process is proposed. Based on the presented design methodology, the effects of the semiconductors blocking voltage and switching frequency on the ηρ-pareto optimisation are evaluated. First, an idealised optimisation is carried out to understand the general behaviour of the optimum point. Second, brute-force optimisation is utilised to find the practical optimum solution based on the market availability of MFT components. Designing MFTs for a 1 MW 10 kV/600 V ISOP-DAB converter is the subject of numerical studies. The best trade-off between ηρ and V f is selected as the final optimal solution and its design correctness is validated using three-dimensional finite-element analysis. Experimental tests on a 3 kW downscaled MFT prototype show that the proposed method is valid in practice. © The Institution of Engineering and Technology 2020",,"Economic and social effects; Multiobjective optimization; Pareto principle; Power converters; Switching frequency; Blocking voltage; Design Methodology; Dual active bridges; Experimental test; Medium frequency transformer; Optimal solutions; Pareto optimisation; Three dimensional finite element analysis; Constrained optimization",,,,,,,,,,,,,,,,"Hurley, W.G., Wölfle, W.H., (2013) Transformers and Inductors for Power Electronics: Theory, Design and Applications, , John Wiley & Sons, UK; Barrios, E.L., Ursua, A., Marroyo, L., Analytical design methodology for litz-wired high-frequency power transformers (2014) IEEE Trans.

The analysis is carried out using a finite element based software SAP 2000 v.14.0.0. An existing model is considered first to validate the present results with the reported one. A convergence study is then performed for the model, considered for investigation, to decide the mesh size for ensuring reliable results. Total 64 models, subjected to dead load and IRC class-A wheel load, are considered for investigation. An exhaustive parametric study is carried out in which the maximum bending moment, maximum shear force, maximum torsional moment, and reactions in girders are calculated. Further, stresses and vertical deflection of bridges are calculated. The results are presented in the form of force ratios between the skew bridge and the straight bridge. The skew angle effect, up to 30°, is almost negligible on forces and deflections, and thus such bridges can be analyzed as a straight one. The influence of other factors like span, span to depth ratio, and girder spacing are also considered for investigation. The results obtained in the syudy may be useful to the design of skew box-girder bridges. © 2020, Journal of Structural Engineering (India).

For the first time, an on-chip MEMS component has been used in the substrate integrated waveguide (SIW) structures to avoid discrete and non-integrated connection problems and high noise levels and affects the operating frequency of telecommunication systems. The behaviour of two capacitors with the fixed-fixed and supported membrane by special spiral arms is analysed and simulated using the finite element method. The MEMS bridges are implemented by a 6 μm gold layer and an air gap of 3 μm. It can be seen that using the new special arms, the movement of the membrane is more uniform than the clamped while the actuation voltage is up to 1.32 V and the tuning range of the capacitor is 29%. Then both the capacitors are placed on half-mode SIW structure and the electromagnetic simulation is done. Finally, the results comparison shows that the frequency tuning range of the MEMS variable capacitor is more significant than the other. © The Institution of Engineering and Technology 2020.",,"Electromagnetic simulation; MEMS; Tuning; Actuation voltages; Design and simulation; Frequency tuning range; High noise levels; MEMS variable capacitors; Micro electromechanical system (MEMS); Operating frequency; Supported membrane; Substrate integrated waveguides",,,,,"Babol Noshirvani University of Technology, BUT: BNUT/ 370557/98","The authors ac?nowledge the funding support of Babol Noshirvani University of Technology through grant program No. BNUT/ 370557/98.",,,,,,,,,,"Zou, J., Liu, C., Schutt-Aine, J., Development of a wide tuning range MEMS tunable capacitor for wireless communication systems (2000) Int.

Typically, the main cable of a long-span, multispan suspension bridge has hundreds of strands. It is essential to understand the frictional resistance between the main cable and saddle for the design and evaluation of the bridge. In order to understand the fundamental mechanism of formation of frictional resistance, this paper studies the frictional resistance between single strand and saddle through finite element analysis. A simple yet effective and efficient model is delivered as a tool for analyzing the frictional resistance between single strand and saddle. The model is validated against model test results, and then used to investigate the distribution of strand force, nominal coefficient of friction, and the friction components at the saddle's side and bottom surfaces. The strand tension distributions are nonuniform along the strand and in the radial direction of the saddle. The friction components at the saddle's side and bottom surfaces follow opposite trends as the relative slip between the strand and saddle increases. © 2020 American Society of Civil Engineers.","Contact; Finite element analysis; Frictional resistance; Multispan suspension bridges","Cables; Suspension bridges; Coefficient of frictions; Design and evaluations; Friction characteristics; Frictional resistance; Fundamental mechanisms; Multi-span suspension bridges; Radial direction; Tension distribution; Friction",,,,,"2011BAG07B03; BHSKL18-01-KF; National Natural Science Foundation of China, NSFC: 51578455, 51778533, 51878561, 51978579; Fundamental Research Funds for the Central Universities: 2682014CX078","This study was funded by the National Natural Science Foundation of China (Grant Numbers 51778533, 51878561, 51978579, and 51578455), the Fundamental Research Funds for the Central Universities (Grant Number 2682014CX078), the National Science and Technology Support Program of China (Grant Number 2011BAG07B03) and the Open Project Funds of State Key Laboratory for Health and Safety of Bridge Structures (Grant Number BHSKL18-01-KF).",,,,,,,,,,"Chai, S., Xiao, R., Wang, X., Ren, X., Analytical method for calculating anti-slip safety factor between main cable and saddle in multitower suspension bridge (2016) China J.

This paper presents a multiscale modeling framework linking four disparate length scales for studying eccentricity and texture evolution in the tube drawing process with standard as well as tilted dies. The main aim of using this methodology was to comprise the anisotropic elastic and plastic behavior of the material and the crystallographic orientations in the FEM model. This multiscale modeling framework starts with electronic scale calculations using the density functional theory approach to calculate the energy variation as a function of lattice parameters as well as the generalized stacking fault energy for copper. The calculated parameters are bridged to the next simulation scale, the atomic scale calculation. Where molecular dynamics simulations are performed to generate mobilities for dislocations and drag coefficients. The dislocation dynamics approach in the microscale then utilized the mobility values to compute the hardening parameters using the Palm-Voce hardening equation. The use of UMAT subroutine allowed to combine the crystal plasticity theory with the FEM model and calculated elastic and plastic parameters. These last ones were imported to the FEM simulations created for a two-step tube drawing process, performed with standard as well as tilted dies. The simulation results were validated using the measured eccentricity, texture, and mechanical properties: they were in a good agreement with the experimental results. © 2020 The Society of Manufacturing Engineers","Crystal Plasticity; Dislocation Dynamics; Molecular Dynamics; Multiscale simulation; Texture evolution; Tube drawing","Anisotropy; Copper; Electronic scales; Hardening; Lattice theory; Molecular dynamics; Textures; Anisotropic behaviors; Atomic-scale calculation; Crystal plasticity theory; Crystallographic orientations; Crystallographic textures; Generalized stacking fault energies; Molecular dynamics simulations; Multi-scale simulation; Density functional theory",,,,,"Deutsche Forschungsgemeinschaft, DFG: PA-837-38-1","We acknowledge the support of the DFG (German Research Foundation) , contract PA-837-38-1 and KME (Kabel Metal Europe) for kindly providing the copper tubes.",,,,,,,,,,"Ravi Kumar, B., Singh, A.K., Das, S., Bhattacharya, D.K., Cold rolling texture in AISI 304 stainless steel (2004) Mater Sci Eng A; Gardner, L., (2012) Tubular Structures XIV: Proceedings of the 14th International Symposium on Tubular Structures, London, UK, 12-14 September 2012, CRC Press/Balkema; Carradò, A., Brokmeier, H.-G., Pirling, T., Wimpory, R.C., Schell, N., Palkowski, H., Development of Residual Stresses and Texture in Drawn Copper Tubes (2013) Adv Eng Mater, 15, pp. 469-475; Foadian, F., Carradó, A., Palkowski, H., Precision tube production: Influencing the eccentricity and residual stresses by tilting and shifting (2015) J Mater Process Technol, 222, pp. 155-162; Carradò, A., Foadian, F., Palkowski, H., Tube Drawing with Tilted and Shifted Die. 60 Excell.

The new design consists of four detector bridges which are presented and optimized. At first, we used FEM simulations to find optimal detectors locations for maximum in-plane and out-of-plane sensitivities. Then, the design of detector bridges is optimized through the investigation of the effect of different designs on the sensitivity. The one using the minimum oxide volume offers the highest sensitivity. This latter is compared with values obtained from a structure using conventional square-shaped heater and detector bridges. Higher sensitivities are demonstrated along the three axes for different heating temperatures. The new structure offers maximum in-plane and out-of-plane sensitivities of 254 mK/g and 20 mK/g, respectively. The resistances of the detectors are designed for the AMS 0.35p.μm CMOS fabrication process and are implemented in an electronic conditioning chain. © 2020 IEEE.","CMOS; convective accelerometer; detector bridges; FEM; MEMS; out-of-plane sensitivity","Accelerometers; CMOS integrated circuits; Integrated circuit design; Bridge design; CMOS fabrication; FEM simulations; Heating temperatures; Micro accelerometers; New detectors; Optimal detectors; Thermal accelerometers; Bridges",,,,,,,,,,,,,,,,"Leung, A.M., Jones, J., Czyzewska, E., Chen, J., Pascal, M., Micromachined accelerometer with no proof mass (1997) International Electron Devices Meeting.

In this study, the fatigue performance of an RC bridge deck repairing technique using ultra-high performance fiber reinforcement concrete (UHPFRC) overlay is assessed experimentally with a wheel-type loading set-up as well as analytically based on finite element method (FEM) using a crack bridging degradation concept. In both approaches, an original RC slab is firstly preloaded to achieve a partly damaged RC slab which is then repaired with UHPFRC overlay and reloaded. The results indicate that the developed analytical method can predict the experimental fatigue behaviors including displacement evolutions and crack patterns reasonably well. In addition, as the shear stress in the concrete/UHPFRC interface stays relatively low over the calculations, this interface can be simply simulated as perfect. Moreover, superior to the experiments, the numerical method provides fatigue behaviors of not only the repaired but also the unrepaired RC slabs. Due to the high strengths and cracking resistance of UHPFRC, the repaired slab exhibited a decelerated deterioration rate and an extended fatigue life compared with the unrepaired slab. Therefore, the proposed repairing scheme can afford significant strengthen effects and act as a reference for future practices and engineering applications.

Transverse attachment joints formed by single-sided welding, similar to rib-to-deck connections in orthotropic steel bridge decks, were fabricated using an LTT welding consumable and conventional welding consumable. Fatigue tests were performed with out-of-plane bending loads using a vibration-type fatigue testing machine. The test results indicated that higher fatigue strength can be achieved in the joint with an LTT consumable compared with a conventional one. In addition, residual stresses around the weld bead were clarified by X-ray diffraction measurements and finite element analyses. The results revealed that the LTT consumable weld metal can reduce residual stress around the weld and also introduce compressive residual stress to the weld root, which can contribute to improved fatigue strength. © 2020, International Institute of Welding.","Fatigue strength; Low transformation temperature welding consumable; Residual stress; Single-sided arc weld; Transverse attachment steel joints; Weld root crack","Bending tests; Bridge decks; Electric welding; Fatigue testing; Residual stresses; Welds; Compressive residual stress; Fatigue strength; Low transformation-temperature; Orthotropic steel bridge decks; Out-of-plane bending; Steel joints; Welding consumables; X-ray diffraction measurements; Fatigue of materials",,,,,,,,,,,,,,,,"Maddox, S.J., (1974) Fatigue of welded joints loaded in bending, Supplementary Report 84UC, , Transport and Road Research Laboratory, Structures Department, Bridges Design Division, Crowthorne, Berkshire; (2012) Manual for design, construction, and maintenance of orthotropic steel deck bridges, , FHWA-IF-12-027; Hirohata, M., Effect of post weld heat treatment on steel plate deck with trough rib by portable heat source (2017) Weld World, 61 (6), pp. 1225-1235. , COI: 1:CAS:528:DC%2BC2sXhs1alsL3N; Ohta, A., Watanabe, O., Matsuoka, K., Siga, C., Nishijima, S., Maeda, Y., Suzuki, N., Kubo, T., Fatigue strength improvement by using newly developed low transformation temperature welding material (1999) Weld World, 43, pp. 38-42. , COI: 1:CAS:528:DC%2BD3cXht1ant7o%3D; Ohta, A., Maeda, Y., Nguyen, N.T., Suzuki, N., Fatigue strength improvement of box section beam by low transformation temperature welding wire (2000) Weld World, 44, pp. 26-30; Ohta, A., Watanabe, O., Matsuoka, K., Maeda, Y., Suzuki, N., Kubo, T., Fatigue strength improvement of box welds by low transformation temperature welding wire and PWHT (2000) Weld World, 44, pp. 52-56. , COI: 1:CAS:528:DC%2BD3cXmsVSktb8%3D; Ohta, A., Suzuki, N., Maeda, Y., Maddox, S.J., Fatigue strength improvement of lap welded joints by low transformation temperature welding wire—superior improvement with strength of steel (2003) Weld World, 47 (3-4), pp. 38-43. , COI: 1:CAS:528:DC%2BD3sXmvFGhsrc%3D; Lixing, H., Dongpo, W., Wenxian, W., Yufeng, Z., Ultrasonic peening and low transformation temperature electrodes used for improving the fatigue strength of welded joints (2004) Weld World, 48 (3-4), pp. 34-39. , COI: 1:CAS:528:DC%2BD2cXmtlyisLg%3D; Barsoum, Z., Gustafsson, M., Fatigue of high strength steel joints welded with low temperature transformation consumables (2009) Eng Fail Anal, 16, pp. 2186-2194. , COI: 1:CAS:528:DC%2BD1MXosFSqsL4%3D; Bhattia, A.A., Barsoum, Z., van der Mee, V., Kromm, A., Kannengiesser, T., Fatigue strength improvement of welded structures using new low transformation temperature filler materials (2013) Procedia Eng, 66, pp. 192-201; Harati, E., Karlsson, L., Svensson, L.E., Dalaei, K., Applicability of low transformation temperature welding consumables to increase fatigue strength of welded high strength steels (2017) Int J Fatigue, 97, pp. 39-47. , COI: 1:CAS:528:DC%2BC2sXkvFOlsw%3D%3D; Miki, C., Anami, K., Improving fatigue strength by additional welding with low temperature transformation welding electrodes (2001) Steel Struc, 1, pp. 25-32; Ohta, A., Suzuki, N., Maeda, Y., Extension of fatigue life by additional welds around box welds using low transformation temperature welding material (2003) High Performance Materials in Bridges.

The FSB system consists of shallow precast, prestressed concrete inverted-Tee beams that are placed adjacent to each other and then involve reinforcement and concrete being placed in the inner joints and deck all in one single cast. Ultra-high-performance concrete (UHPC) is becoming more widely used in bridge construction applications as a result of its remarkable structural performance. Many departments of transportation have tested and deployed the use of UHPC in bridges around the United States. Most of these applications have been to connect precast members (e.g., slabs to beams and slabs, adjacent beams, caps to columns, etc.). A modified FSB design is desired to eliminate the cast-in-place (CIP) deck and allow for UHPC to be used in the joint region, which will allow for accelerated construction and decrease the impact of construction on traffic. Different joint details and cross-section geometries were analyzed and experimentally evaluated to determine feasible joint details with UHPC for slab beam bridges used in accelerated construction. Results from numerical modeling, strength, and fatigue experimental testing of the transverse joint performance of four different UHPC joints in two different depth slab beam bridges are presented. Straight-side and shear-key UHPC joint details were found to behave similar to or better than the current FSB joint detail. © 2020 American Society of Civil Engineers.","Accelerated bridge construction; Non-linear finite-element analysis; Prefabricated elements and systems; Slab beam bridge; Ultra-high-performance concrete","Concrete beams and girders; Precast concrete; Prestressed concrete; Shear flow; Ultra-high performance concrete; Accelerated constructions; Bridge constructions; Cross-section geometry; Departments of transportations; Experimental testing; Florida Department of Transportation; Structural performance; Ultra high performance concretes (UHPC); Bridges",,,,,"Florida Department of Transportation, FDOT","The research presented in this project was supported by the Florida Department of Transportation (FDOT).

A nonlinear finite element model was first established and validated against experimental results. Subsequently, another 89 nonlinear finite element models with different connector quantities, connector arrangements, abutment widths, and shear-span ratios were studied. An analytical calculation method considering the moment contribution of perfobond connectors and the shear force distribution on perfobond connectors at ultimate was then proposed, verified against experimental and numerical results, and was compared with current calculation methods. Results show that, compared with current methods, the proposed method predicts the flexural strengths of the connections with better accuracy, with the average predicted-actual ratio being 0.96 and the coefficient of variation being 0.09. The flexural strengths of girder-abutment connections are significantly affected by girder embedded length, abutment width, and the quantity and arrangement of perfobond connectors. The flexural strengths are higher when connectors are set close to the girder end. When increasing the quantity of perfobond connectors, the flexural strengths of the connections could increase by 86% at most. With the same connector quantity, the flexural strengths could vary 20% with different connector arrangements. © 2020 Elsevier Ltd","Analytical study; Fully integral abutment bridge (FIAB); Girder-abutment connection; Perfobond connector; Ultimate behavior","Abutments (bridge); Bending strength; Concrete bridges; Finite element method; Numerical methods; Shear flow; Steel beams and girders; Analytical calculation; Coefficient of variation; Flexural behavior; Integral abutment bridge; Non-linear finite element model; Numerical results; Shear force distribution; Shear span ratio; Concrete beams and girders; bridge; concrete structure; finite element method; flexure; nonlinearity; numerical model; steel structure; strength; structural analysis; structural component",,,,,"China Scholarship Council, CSC: 201806260196, 201906260170","The first author and the third author would like to acknowledge the financial support provided by the China Scholarship Council (CSC) [Grant number: 201906260170 ; 201806260196 ].",,,,,,,,,,"Yang, F., Liu, Y., Xin, H., Negative bending capacity prediction of composite girders based on continuous strength method (2018) Thin-Walled Struct., 129, pp. 278-288; Marques Lima, J., de Brito, J., Inspection survey of 150 expansion joints in road bridges (2009) Eng.

Based on energy principles and variational principles, a vibration differential equation and the natural boundary conditions of a CBGCSW were developed. The analytical calculation formula for solving the vibration differential equation was then obtained. The results calculated using the ANM agreed well with previous experimental results, which validated the correctness of ANM. To demonstrate the superiority of the ANM, the vibration frequencies of several abstract CBGCSWs with varying ratios of span-width, obtained using the elementary beam theory (EBT) and the finite element method (FEM), were compared with those obtained by ANM. The efficacy of the ANM was verified and some meaningful conclusions were drawn which are helpful to relevant engineering design, such as the observation that a higher natural vibration frequency and smaller span-width ratio significantly magnified the shear lag effect of CBGCSW. The first five-order natural vibration frequencies of the CBGCSW were significantly lower than those of the composite box girder bridge with general steel web (CBGGSW), which indicates that the impact of the accordion effect is significant. © 2020 by the authors.","Accordion effect; Analytical method; Corrugated steel webs; Shear lag effect; Span-width ratios",,,,,,"2019RS3009; National Natural Science Foundation of China, NNSFC: 51778630, CLRQT-2015-010, U1934207; Central South University, CSU: 502501006; Fundamental Research Funds for Central Universities of the Central South University: 2018zzts189","Funding: This research was funded by the National Natural Science Foundations of China (U1934207 and 51778630), the Experimental Foundations of the New Railway from Chengdu to Lanzhou (CLRQT-2015-010), the Hunan Innovative Provincial Construction Project (2019RS3009), and the Innovation-driven Plan in Central South University (502501006), the Fundamental Research Funds for the Central Universities of Central South University (2018zzts189).","This research was funded by the National Natural Science Foundations of China (U1934207 and 51778630), the Experimental Foundations of the New Railway from Chengdu to Lanzhou (CLRQT-2015-010), the Hunan Innovative Provincial Construction Project (2019RS3009), and the Innovation-driven Plan in Central South University (502501006), the Fundamental Research Funds for the Central Universities of Central South University (2018zzts189).",,,,,,,,,"Liu, S., Ding, H., Taerwe, L., De Corte, W., Shear Strength of Trapezoidal Corrugated Steel Webs for Horizontally Curved Girder Bridges (2019) Appl.

The magnet is made of a single Nb3Sn wire and designed for a fourth-generation ECR ion source operating at frequency of 45 GHz. To effectively prevent the wires motion from performance degradations and a quench, a pre-stress is essential for the superconducting magnet winding and strengthening. Focusing on the sextupole magnet's assembly and the pre-load procedure, a combined support structure with temporary bladders, load pads, and load keys, as well an aluminum shell was designed and fabricated in this work. A whole assembly process was fulfilled with a dummy structure at room temperature and a cooling-down and warming-up cycle to show its validity. Some low-Temperature resistance strain gauges, together with a half-bridge compensation, were used to monitor strain of the aluminum shell during the pre-load control performance and thermal cycle process. A parametric study on the equivalent friction of the combined structure was carried out for the mechanical characteristics based on FEM simulation to show a reasonable agreement with the experiment measurements as a proper friction coefficient chosen. Finally, a real sextupole magnet was assembled with the combined support structure and tested for excitation. It was illustrated that a proper pre-load state realized by the support structure and a high excitation current about 800 A was reached so that the excited magnetic field gained 7 T as the designed value. © 2002-2011 IEEE.","Bladder and key technology; mechanical analysis; Nb3Sn magnets; strain measurements; support structure","Binary alloys; Excited states; Friction; Ground supports; Ion sources; Magnets; Niobium alloys; Solenoids; Strain measurement; Thermal cycling; Tin alloys; Excitation currents; Friction coefficients; Key technologies; Low-temperature resistance; Mechanical analysis; Mechanical characteristics; Performance degradation; Support structures; Superconducting magnets",,,,,"National Natural Science Foundation of China, NSFC: 11427904; Youth Innovation Promotion Association of the Chinese Academy of Sciences: 2019404","Manuscript received September 22, 2019; accepted February 24, 2020.

Firstly, a converter with motor phases grouped in pairs which share one common converter phase is introduced. This discrete-type converter is equivalent to the asymmetrical half-bridge converter (AHBC) in terms of the number of semiconductor components and functionality. The common converter phase concept enables modularization using two standard, commercially available six-pack IGBT modules, thus simplifying mass production. Compared to existing modular topologies, the proposed modular converter has the advantage of enabling an overlap of current pulses, which is a key feature for the SRM performance at elevated speeds while retaining a minimal number of standard power switch modules. In addition, owing to inherent operating regimes, the proposed modular converter enhances the motor performance over almost the entire range of the exploitation characteristics compared to AHBC and existing modular topologies. The advantages of the proposed modular topology were determined by means of finite element method (FEM) simulations. Experiments confirm the conclusions obtained from FEM analysis and verify the feasibility of the proposed modular converter. © 2020, Springer-Verlag GmbH Germany, part of Springer Nature.","Finite element method (FEM);

When load ratings result in rating factor values of less than one, bridges and culverts must often be posted to limit the speed and weight of vehicles traveling over them. In many cases, such restrictions could significantly limit or prevent traffic flow and are costly. To evaluate the dynamic response of a structure, a dynamic amplification factor (DAF) is applied to the response of the structure subjected to an equivalent static load. American Association of State Highway and Transportation Officials (AASHTO) guidelines specify the DAF for culverts as a function of only fill depth. Studies have shown that AASHTO-calculated DAFs can be overly conservative in many cases, thus resulting in the unnecessary posting of culverts. Though this issue is relatively widely recognized, a better alternative for determining DAFs has yet to be proposed and accepted. In the results reported in this paper, DAFs were calculated from the static and dynamic response of 83 unique pavement-soil-culvert models using three-dimensional (3D) finite element analyses (FEAs). Four parameters were chosen and varied across three values to assess their effect on the DAF. The parameters included the span length, the asphalt pavement thicknesses, the soil fill depth, and the elastic modulus used to characterize the soil. Two additional models, with intermediate fill depths, were also analyzed. The results of this study indicate that, compared with the other parameters, DAFs are most affected by changes in the fill depth. However, contrary to AASHTO’s guidelines, the DAF increases with increasing fill depth. © 2020, Springer Science+Business Media, LLC, part of Springer Nature.","Culvert; Dynamic load allowance; Finite element analysis; Infinite elements; Load rating",,,,,,,,,,,,,,,,,"AASHTO, Manual for bridge evaluation (2nd edition) with 2011, 2013, 2014, 2015 and 2016 interim revisions. 2011, American Association of State Highway and Transportation Officials (AASHTO), Washington, D.C; (2013) Interim Revisions, p. 2012. , American association of state highway and transportation officials, Washington, D.C; Bakhtpinjarkar, B.S.G., (1989) Review of Dynamic Testing of Highway Bridges, , in Structures research report SRR-89-01, Ontario Ministry of Transportation, Downsview, Canada; Beben, D., Dynamic amplification factors of corrugated steel plate culverts (2013) Eng.

In this study, four PCFST column specimens were tested under constant eccentrically loaded and out-of-plane horizontal cyclic loading. The elasto-plastic behaviour and failure mode of these specimens were investigated. Secondly, the FE models of these four experimental PCFST columns were established, through comparisons with the experimental results, the validity of the selected elements, mesh division, the contact relationship between the concrete and the steel pipe, and the boundary conditions of FE models were verified. Thirdly, 30 FE models of PCFST bridge piers were analyzed to ascertain the effects of slenderness ratio λ, radius-thickness ratio Rt, and vertical load eccentricity ratio e/L on ultimate strength and ductility. Finally, an empirical formula was proposed to describe the ultimate strength and ductility of such bridge piers for engineering application under complicated loading conditions. © 2020, Korean Society of Civil Engineers.","Concrete-filled;

The macro model represents the non-linear soil structure interaction (SSI) exemplified by a suspension bridge anchor-block. The model can be adjusted and used for other structures. The formulation uses an elasto-plastic framework to calculate the foundation response. A yield surface in the V – M - H (Vertical, Moment and Horizontal loading) load-space defines the yield and failure envelopes. A non-associated potential surface and a simple bi-linear hardening law describe the magnitude as well as the direction of the plastic displacements. Calibration of model parameters are performed through 2D and 3D finite element calculations. The model is suited for integration in a program for structural design. Compared to a full finite element model, the macro model simplifies the soil structure interaction analyses significantly. The yield and potential surfaces include the option to modify the shape in the H − V plane versus the M − V plane. Allowing for this flexibility in the formulation improves modeling of foundation uplift behavior. The paper demonstrates calibration of macro model parameters through a calculation example. Validation of the model by prototype testing in a sand bin is also performed and presented. © 2017 Elsevier Ltd",,"Calibration; Soil structure interactions; Soils; Structural design; 3-D finite elements; Failure envelope; Foundation uplift; Horizontal loading; Plastic displacement; Potential surfaces; Prototype testing; Shallow foundations; Finite element method",,,,,,,,,,,,,,,,"Terzaghi, K., Theoretical soil mechanics (1943), John Wiley = Sons New York, NY; Brinch-Hansen, J., (1970) A revised and extended formula for bearing capacity, vol.

In actual construction, the inner CFST is erected prior to the casting of the outer reinforced concrete part to support the construction preload, after which the whole composite member is under sustained service load. The complex loading sequence leads to highly nonlinear material interaction and consequently complicated structural performance. This paper studies the full-range behaviour of concrete-encased CFST columns with initial preload on inner CFST followed by sustained service load over the whole composite section. Validated against the reported data obtained from specifically designed tests, a finite element analysis model is developed to investigate the detailed structural behaviour in terms of ultimate strength, load distribution, material interaction and strain development. Parametric analysis is then carried out to evaluate the impact of significant factors on the structural behaviour of the composite columns. Finally, a simplified design method for estimating the sectional capacity of concrete-encased CFST is proposed, with the combined influences of construction preload and sustained service load being taken into account. The feasibility of the developed method is validated against both the test data and the simulation results.

A three-span highway bridge in Michigan is instrumented with a structural monitoring system to observe the flexural response of the spans to vehicular loads. The monitoring system is designed to offer data for quantitative assessment of the degree of composite action in composite and noncomposite sections of the bridge spans using the position of neutral axis and the magnitude of slip strain as key response parameters correlated to composite action. It is shown that unintended nonlinear partial composite action exists in negative bending regions of the bridge. A calibrated analytical model and a finite-element model are developed based on empirical observation allowing tensile strains in the deck to be estimated under load. Estimated surface strains are compared with those with the design assumption of no composite action at the slab-girder interface. It is concluded that the observed partial composite action results in higher tensile strains in the deck which is a likely culprit to accelerated deck deterioration. © 2020 American Society of Civil Engineers.","Composite action; Deck deterioration; Durability; Neutral axis; Slip strain; Structural health monitoring","Bridges; Concrete bridges; Deterioration; Durability; Monitoring; Structural health monitoring; Tensile strain; Composite action; Durability assessment; Long-term structural monitoring; Neutral axis; Quantitative assessments; Response parameters; Slip strains; Structural Monitoring Systems; Highway bridges; bridge; data; durability; finite element method; loading; strain; structural analysis; structural response; Michigan; United States",,,,,"National Science Foundation, NSF: ECCS-1446330, ECCS-1446521","This work was supported by the National Institute of Standards and Technology (NIST) Technology Innovation Program (Cooperative Agreement 70NANB9H9008) and the National Science Foundation (NSF) (Grants ECCS-1446521 and ECCS-1446330).

A recurring problem with this type of bridge is cracking in the longitudinal joints between adjacent beams. Many research results have indicated that efficient joint material should have small or zero shrinkage at an early age and achieve sufficient bond strength at the interface between the joint and the box beam. As the first part of a comprehensive study, two phases of material properties tests were conducted to select the best material for the joint between adjacent box beams to resist cracking. During Phase I work, four potential joint materials were tested and evaluated based on shrinkage, flexural tensile strength, and normal bond strength. During Phase II work, time-dependent material testing was conducted on the materials selected from Phase I to characterize the nonlinear changes in bond, compressive, and tensile strength with time. In addition, three-dimensional (3D) finite-element models (FEMs) were developed to calculate the early-age joint stress distribution and evaluate the structural performance of a Type IV joint grouted with epoxy grout and a Type V joint filled with shrinkage-compensated concrete. A finite-element modeling approach that is capable of simulating early-age joint behavior was illustrated, and models were developed for beam-joint-beam structures that were 1.2 m (4 ft) long. The analytical results indicated that a Type V joint filled with shrinkage-compensated concrete is expected to better resist joint cracking than a Type IV joint filled with epoxy. Although the FEM results indicated that a Type V joint filled with shrinkage-compensated concrete still induces tensile stress near the exterior of the interface, placing reinforcement near the edge will provide sufficient capacity to resist debonding at the interface during the early-age period when initial cracking has been found to occur. © 2020 American Society of Civil Engineers.","Adjacent-box-beam bridges; Early-age shrinkage-compensated concrete; Finite-element modeling; Joint cracking","Bond strength (materials); Concrete beams and girders; Concrete placing; Finite element method; Grouting; Mortar; Precast concrete; Tensile strength; Tensile testing; Analytical results; Box beam; Concrete box beams; Early age shrinkages; Longitudinal joint; Material selection; Structural performance; Three-dimensional (3D) finite element models; Shrinkage; concrete; cracking (fracture); finite element method; grout; material flow analysis; shrinkage; strength; structural component; time dependent behavior",,,,,,,,,,,,,,,,"(2014) AASHTO LRFD Bridge Design Specifications, , AASHTO. 3rd ed.

The two-layer experimental model were composed of 12 unit curtain walls, of which there are 2 beams at a distance of 1.2 m from the top and bottom in 9 unit curtain walls respectively, and there is only one beam at a distance of 1.2 m from the top in 3 unit curtain walls. The dimension of each unit curtain wall is 1.2 m × 4.0 m. The section shape of the experimental model is L-shaped. Firstly, the experimental investigation and analysis of the model with arrangement of one pair of hooks under positive and negative wind were carried out. Secondly, the experimental investigation and analysis of the model with no hooks under positive and negative wind were carried out. The out-of-plane deformation, in-plane deformation and the strain of the columns were collected and analyzed. Finally, finite element analysis model was established. The similarities and differences of the analysis results and the experimental results were analyzed. The results show that the beam has a small constraint on the columns whether the wind pressure is positive or negative when the number and position of hooks are reasonable. When the wind pressure is negative, the hook has little effect on the out-of-plane deformation and stability. Under the action of positive wind, the hooks can significantly reduce the in-plane deformation and restrain the lateral torsion deformation of the columns. © 2020, Korean Society of Civil Engineers.","Aluminum alloy column; Experimental study; Numerical simulation; Unit glass curtain wall; Wind resistance performance","Bridge cables; Computer simulation; Deformation; Glass; Hooks; Numerical models; Structural dynamics; Wind effects; Experimental investigations; Experimental study; Finite element analysis model; Glass curtain walls; Load-bearing performance; Numerical simulation analysis; Out-of-plane deformations; Wind resistance; Aluminum alloys",,,,,"20A560026; 2019GGJS147; Missouri University of Science and Technology, MST","This study is funded by the Key Scientific Research Project of Institution of Higher Education in Henan Province (20A560026) and Training Plan for Young Key Teachers in Institution of Higher Education in Henan Province (2019GGJS147).

This macromolecule shows two main age-related alterations, which are the decrease of both molecular diameter (due to the loss of hydration) and number of hydrogen bonds. In this work, it is proposed to investigate the influence of these two parameters (molecular diameter and number of hydrogen bonds) on the mechanical behavior of tropocollagen using finite element method. To this end, a novel three-dimensional finite element model of collagen molecule accounting for hydrogen bonds was developed. Then, a numerical design of experiments for the diameter of tropocollagen and variations in the number of hydrogen bonds has been established. The mechanical properties (“load–strain” curve and apparent Young’s modulus) of the collagen molecule were obtained by employing the proposed model to uniaxial tensile tests. The parametric study demonstrates that the mechanical properties of tropocollagen are slightly affected by the rate of hydration but considerably affected by variation of the number of hydrogen bonds. Finally, a fitted analytical function was deduced from the above results showing effects of the two parameters (hydration rate and hydrogen bonds) on the apparent Young’s modulus of tropocollagen. This study could be useful to understand the influence of structural age modifications of tropocollagen on the macroscopic mechanical properties of bone. © IMechE 2020.","Bone aging; design of experiments; hydrogen bonds; molecular diameter; response surface methodology; three-dimensional finite element modeling; tropocollagen","Collagen; Composite bridges; Design of experiments; Finite element method; Hydration; Molecules; Strain; Tensile testing; Analytical functions; Macroscopic mechanical properties; Molecular diameter; Molecular modification; Response surface methodology; Three dimensional finite element model; tropocollagen; Uniaxial tensile test; Hydrogen bonds; tropocollagen; water; biomechanics; chemistry; hydrogen bond; mechanical stimulus test; mechanics; metabolism; molecular model; tensile strength; Biomechanical Phenomena; Hydrogen Bonding; Mechanical Phenomena; Mechanical Tests; Models, Molecular; Tensile Strength; Tropocollagen; Water",,"water, 7732-18-5; Tropocollagen; Water",,,"Fondation pour la Recherche Médicale, FRM: DIC20161236439","The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: The authors acknowledge the financial support provided by the Fondation pour la Recherche Médicale (FRM) (Project: DIC20161236439)",,,,,,,,,,"Rho, J.Y., Kuhn-Spearing, L., Zioupos, P., Mechanical properties and the hierarchical structure of bone (1998) Med Eng Phys, 20 (2), pp. 92-102; Raspanti, M., Congiu, T., Guizzardi, S., Tapping-mode atomic force microscopy in fluid of hydrated extracellular matrix (2001) Matrix Biol, 20 (8), pp. 601-604; Habelitz, S., Balooch, M., Marshall, S.J., In situ atomic force microscopy of partially demineralized human dentin collagen fibrils (2002) J Struct Biol, 138 (3), pp. 227-236; Hambli, R., Katerchi, H., Benhamou, C.L., Multiscale methodology for bone remodelling simulation using coupled finite element and neural network computation (2011) Biomech Model Mechanobiol, 10 (1), pp. 133-145; Hambli, R., Apparent damage accumulation in cancellous bone using neural networks (2011) J Mech Behav Biomed Mater, 4 (6), pp. 868-878; Boskey, A.L., Coleman, R., Aging and bone (2010) J Dent Res, 89 (12), pp. 1333-1348; Wallace, J.M., Rajachar, R.M., Allen, M.R., Exercise-induced changes in the cortical bone of growing mice are bone and gender specific (2007) Bone, 40 (4), pp. 1120-1127; Chen, J.H., Liu, C., You, L., Boning up on Wolff’s law: mechanical regulation of the cells that make and maintain bone (2010) J Biomech, 43 (1), pp. 108-118; Currey, J.D., The relationship between the stiffness and the mineral content of bone (1969) J Biomech, 2 (4), pp. 477-480; Tommasini, S.M., Nasser, P., Schaffler, M.B., Relationship between bone morphology and bone quality in male tibias: implications for stress fracture risk (2009) J Bone Min Res, 20 (8), pp. 1372-1380; Nagaraja, S., Lin, A.S.P., Guldberg, R.E., Age-related changes in trabecular bone microdamage initiation (2007) Bone, 40 (4), pp. 973-980; Martin, G.M., Sprague, C.A., Epstein, C.J., Replicative life-span of cultivated human cells.

However, little research has been conducted on the transverse-moment distribution of the slab in TGCBC bridges and the slab moment prediction method capable of considering the effects of actual configurations and dimensions is not available in the current TGCBC bridge design practice. Recommendations by design codes for continuous slabs in steel or concrete bridges have not considered the structural characteristics of TGCBC bridges, which may result in an uneconomical or unsafe slab design for TGCBC bridges. In this paper, finite-element analyses were conducted on an existing TGCBC bridge to investigate the transverse-moment distribution of its concrete slab under external loads. A simplified method based on a frame model for predicting the transverse-moment distribution coefficients was then proposed. The effects of geometric parameters and cracking of concrete slabs on the transverse-moment distribution coefficients were also examined through a parametric analysis. The analysis results show that the transverse bending stiffness of steel plate girders, which is mainly determined by the layouts of web transverse stiffeners and crossbeams, has a significant influence on the transverse-moment distribution of the slab. Additionally, the distribution coefficients are also dependent on the geometric parameters of TGCBC bridges as well as the magnitude of external loads. The results also show that the transverse-moment distribution coefficients could be precisely estimated by the proposed simplified method. © 2020 American Society of Civil Engineers.","Finite-element analysis; Frame model; Steel plate girder; Transverse-moment distribution; Twin-girder crossbeam composite (TGCBC) bridge; Web transverse stiffener","Beams and girders; Box girder bridges; Composite bridges; Finite element method; Plates (structural components); Structural optimization; Cracking of concrete; Distribution coefficient; Frame models; Moment distribution; Parametric -analysis; Steel plate girders; Structural characteristics; Transverse stiffener; Concrete slabs",,,,,,,,,,,,,,,,"(2002) Standard Specifications for Highway Bridges, , AASHTO. 17th ed.

The uncertain finite element model updating method based on sequential optimization strategy is studied, and the uncertain modal parameter data obtained by health monitoring system are applied to upgrade the uncertain finite element model of cable-stayed bridges, which provides a more accurate finite element model for subsequent reliability analysis. Firstly, the finite element dynamic analysis of the main span structure of the bridge is carried out, and the natural frequencies and modes are obtained. Then the measured natural frequencies of the structure are obtained by estimating the power spectrum of the dynamic monitoring data, and the theoretical values are compared with the measured ones. The dynamic characteristics of the modified two-stayed bridge finite element model are verified by the load test results. The results show that the modified finite element model can simulate the dynamic characteristics of the actual structure well. Most of the measured and calculated displacement increments were within the margin of error. The error is within 5%, which can accurately reflect the true stress state of the structure. The uncertainty model based on the sequential optimization strategy is simple and can be applied to the uncertainty of the finite element model of the actual bridge structure. © 2020, Strojarski Facultet.

Three T-beam bridges were field tested under high bending moment and their strain response was recorded. The results allowed two of these bridges’ HL-93 flexural rating factors to be increased to above 1.0, suggesting their ability to carry larger loads than predicted. A novel, nonlinear proxy finite element analysis (PFEA) technique was developed which enables the computationally efficient prediction of bridge response up to failure while accounting for girder ductility and load redistribution in the three-dimensional structure. PFEA uses a genetic algorithm to optimize constitutive and geometric parameters assigned to a shell element discretization of each girder that possesses moment-curvature response equivalent to that of the solid reinforced concrete T-beam sections. The resulting elastic and elastic-plastic shell element discretization is straightforward to implement in a three-dimensional model of a complete bridge using commercial finite element software. Using PFEA, the three field-tested bridges were analyzed and load rated, with resulting ratings consistently greater than those calculated by AASHTO and consistent with or greater than those inferred from field testing. The PFEA technique accurately predicts the real bridges’ longitudinal and transverse load responses, and incorporates both girder ductility and load redistribution while also being able to assess bridges with non-uniform geometry. © 2019 Institution of Structural Engineers","Bridge load rating; Finite element analysis; Genetic algorithms; Live-load testing; Moment-curvature analysis",,,,,,"U.S. Department of Transportation, DOT; University of Maine: 69A3551847101; Maine Department of Transportation, MaineDOT","The research reported in this paper was conducted with financial and logistical support from the MaineDOT, whose assistance with field testing is greatly appreciated.

One of the most outstanding characteristics of the new temporary road was that it passed underneath the piers of a continuous reinforced concrete bridge. The additional loads caused by the road construction and later on operation with heavy trucks potentially jeopardized the safety of bridges. The objective of this study was to examine the influence of the road construction and operation on the behavior of bridge piers and foundation piles. In addition, the effectiveness of a retrofit countermeasure of using steel sheet walls for improving the stability of the bridge was studied. A detailed three-dimensional finite element (FE) model, capable of addressing the interactions between pier columns, pile foundations, surrounding soils, and heavy truckloads, was developed to facilitate the analyses. After validating the model with the common analytical M method, the developed model was employed to investigate the behavior of bridge under the combined effects from temporary road loads (i.e., soil excavation load, pavement weight, and heavy truckloads). Field measured data from a tilt health monitoring system were utilized to verify the performance of FE analyses and confirm the performance of the retrofit countermeasure for pier deformation control. The steel sheet walls were found to be effective in increasing the safety of existing bridge piers. © 2019 Elsevier Ltd","Bridge pier; Deformation control; Field Monitoring Validation; Finite Element Analysis; Pier-Pile-Soil Model","Bridge piers; Deformation; Finite element method; Land reclamation; Pile foundations; Piles; Reinforced concrete; Retrofitting; Road construction; Soils; Steel sheet; Temporary roads; Trucks; Additional loads; Deformation control; Field monitoring; Field-measured data; Health monitoring system; Pier piles; Surrounding soils; Three dimensional finite elements; Highway bridges",,,,,"2018YFC0809606; GJHZ20180418190651055, JCYJ20170811155517130; National Natural Science Foundation of China, NSFC: 51978215; Natural Science Foundation of Guangdong Province: 2017A030313290","This work is financially supported by the National Key R&D Program of China (No. 2018YFC0809606 ), National Natural Science Foundation of China (No. 51978215 ), Natural Science Foundation of Guangdong Province (No. 2017A030313290 ), Shenzhen S&T Projects (No. JCYJ20170811155517130 and GJHZ20180418190651055 ).

This paper presents an improved shape-finding method which can overcome the shortcomings of the previous shape-finding method. The improved method is based on the common finite element analysis and convenient to be widely used in normal engineering practice. The main step can be summarized as follows. First, the vertical force components of the hangers are determined according to the construction method. Second, in the midspan, the initial equilibrium state of the main cable is calculated iteratively based on the Newton–Raphson method. Third, in the side span, the shape finding for the main cable is executed according to the horizontal force equilibrium of the pylon. Finally, the full-bridge model is obtained and examined carefully. The improved method is demonstrated through one suspension bridge with a planar cable system and one with a spatial cable system. The results show that the improved method is more efficient and accurate compared with the previous shape-finding method. © 2019, Korean Society of Steel Construction.","Newton–Raphson method; Planar cable system; Shape-finding method; Spatial cable system; Suspension bridge","Cables; Iterative methods; Struts; Suspension bridges; Suspensions (components); Construction method; Engineering practices; Initial equilibrium state; Long span suspension bridges; Planar cable; Raphson methods; Shape finding; Spatial cable; Cable stayed bridges",,,,,"Natural Science Foundation of Shanghai: 14ZR1439000; National Natural Science Foundation of China, NSFC: 51378387","The authors gratefully appreciate the financial support from the National Natural Science Foundation of China (Grant Number 51378387) and the Natural Science Foundation of Shanghai (Grant Number 14ZR1439000).",,,,,,,,,,"Fulmer, S.J., Kowalsky, M.J., Nau, J.M., Grouted shear stud connection for steel bridge substructures (2015) Journal of Constructional Steel Research, 109, pp. 72-86; Gimsing, N.J., (1983) Cable supported bridges: Concepts and design, , Wiley, Chichester; Hanaor, A., Prestressed pin-jointed structures—Flexibility analysis and prestress design (1988) Computers & Structures, 28 (6), pp. 757-769; Jung, M.R., Min, D.J., Kim, M.Y., Nonlinear analysis methods based on the unstrained element length for determining initial shaping of suspension bridges under dead loads (2013) Computers & Structures, 128, pp. 272-285; Kim, H.K., Kim, M.Y., Efficient combination of a TCUD method and an initial force method for determining initial shapes of cable-supported bridges (2012) International Journal of Steel Structures, 12 (2), pp. 157-174; Kim, H.K., Lee, M.J., Chang, S.P., Non-linear shape-finding analysis of a self-anchored suspension bridge (2002) Engineering Structures, 24 (12), pp. 1547-1559; Kim, H.K., Lee, M.J., Chang, S.P., Determination of hanger installation procedure for a self-anchored suspension bridge (2006) Engineering Structures, 28 (7), pp. 959-976; Kim, K.S., Lee, H.S., Analysis of target configurations under dead loads for cable-supported bridges (2001) Computers & Structures, 79 (29-30), pp. 2681-2692; Kim, M.Y., Kim, D.Y., Jung, M.R., Attard, M.M., Improved methods for determining the 3 dimensional initial shapes of cable-supported bridges (2014) International Journal of Steel Structures, 14 (1), pp. 83-102; Li, J.H., Feng, D.M., Li, A.Q., Yuan, H.H., Determination of reasonable finished state of self-anchored suspension bridges (2016) Journal of Central South University, 23 (1), pp. 209-219; Luo, X., Xiao, R., Xiang, H., Cable shape analysis of suspension bridge with spatial cables (2004) Journal of Tongji University, 32 (10), pp. 1349-1354. , (in Chinese; Luo, Z.L., Dong, F.H., Statistical investigation of bearing capacity of pile foundation based on Bayesian reliability theory (2019) Advances in Civil Engineering; Rahnavard, R., Khaje, M.T., Hassanipour, A., Siahpolo, N., Parametric study of seismic performance of steel bridges pier rehabilitated with composite connection (2017) Journal of Structure and Construction Engineering; Such, M., Jimenez-Octavio, J.R., Carnicero, A., Lopez-Garcia, O., An approach based on the catenary equation to deal with static analysis of three dimensional cable structures (2009) Engineering Structures, 31 (9), pp. 2162-2170; Sun, B., Cai, C.S., Xiao, R.C., Analysis strategy and parametric study of cable-stayed-suspension bridges (2013) Advances in Structural Engineering, 16 (6), pp. 1081-1102; Tang, M., Qiang, S., Shen, R., Segmental catenary method of calculating the cable curve of suspension bridge (2003) Journal of the China Railway Society, 25 (1), pp. 87-91. , (in Chinese; Wang, X., Lei, X., Wang, C., Xu, Y., Spatial transformation control method of main cable alignment during construction process in suspension bridge with spatial cables (2017) Engineering Mechanics, 34 (4), pp. 187-195. , (in Chinese; Xiao, R.C., Chen, M.H., Sun, B., Determination of the reasonable state of suspension bridges with spatial cables (2017) Journal of Bridge Engineering; Zhang, J., Liu, A., Ma, Z.J., Huang, H., Mei, L., Li, Y., Behavior of self-anchored suspension bridges in the structural system transformation (2012) Journal of Bridge Engineering","Sun, B.; Department of Bridge Engineering, China; email: sunbin@tongji.edu.cn",,,"Korean Society of Steel Construction",,,,,15982351,,,,"English","Int.

A single row of steel H-piles (SHPs) is commonly used at the thin and stub abutments of IABs to form a flexible support system at the bridge ends to accommodate thermal-induced displacement of the bridge. Consequently, as the IAB expands and contracts due to temperature variations, the SHPs supporting the abutments are subjected to cyclic lateral (longitudinal) displacements, which may eventually lead to low-cycle fatigue (LCF) failure of the piles. In this paper, the potential of using finite element (FE) modeling techniques to estimate the LCF life of SHPs commonly used in IABs is investigated. For this purpose, first, experimental tests are conducted on several SHP specimens to determine their LCF life under thermal-induced cyclic flexural strains. In the experimental tests, the specimens are subjected to longitudinal displacements (or flexural strain cycles) with various amplitudes in the absence and presence of a typical axial load. Next, nonlinear FE models of the tested SHP specimens are developed using the computer program ANSYS to investigate the possibility of using such numerical models to predict the LCF life of SHPs commonly used in IABs. The comparison of FE analysis results with the experimental test results revealed that the FE analysis results are in close agreement with the experimental test results. Thus, FE modeling techniques similar to that used in this research study may be used to predict the LCF life of SHP commonly used in IABs.

Firstly, each group of replacement suspenders is separated from the pocket hanging system regardless of the constraint effect of the bridge deck on the suspenders, and the force analysis is carried out to obtain the displacement of the bridge deck under different cases; Then, the modified coefficient is obtained by using the measured displacement at the lower end of each suspender, and the modified coefficient is used to modify the displacement of the bridge deck, so that the calculation result can be applied to the case where the stiffness of the bridge deck cannot be ignored; Finally, the correctness of the method in this paper is verified by applying it to practical engineering. It can be concluded that the proposed method is simple, easy to operate and has high precision, which can be used in the removal of arch bridge suspenders through the verification results.

This is predetermined by that a given structure is the most common, simple, and technological. The result of the development of such electric machines is a possibility to build a combined series of induction motors and magnetoelectric synchronous machines. In these machines, replacing a short-circuited rotor by a rotor with permanent magnets and controlled working magnetic flux turns the induction machine into a magnetoelectric synchronous one. All existing generators with permanent magnets have a major drawback: there is almost no possibility to control output voltage and, in some cases, power. This is especially true for autonomous power systems. Known methods of output voltage control lead to higher cost, compromised reliability, deterioration of mass-size indicators. This paper reports the construction of a three-dimensional field mathematical model of a magnetoelectric synchronous generator with permanent magnets. The model has been implemented using a finite element method in the software package COMSOL Multiphysics. We show the distribution of the electromagnetic field in the active volume of the generator under control and without it. The impact of a control current in the magnetized winding on the external characteristics of the generator at a different coefficient of load power has been calculated. Applying the devised model has enabled the synthesis of a current control law in the magnetizing winding at a change in the load over a wide range. The results obtained demonstrate that it is possible to control output voltage of the generator with permanent magnets by using an additional magnetizing winding. The winding acts as an electromagnetic bridge for the main magnetic flux, which is created by permanent magnets. Our analysis of results has shown that it is possible to regulate the output voltage of the generator with constant magnets within –35 %, +15 %. © 2020 Vadim Chumack, Serhii Tsyvinskyi, Mykhailo Kovalenko, Alexej Ponomarev, Ihor Tkachuk.","generator voltage control; magnetizing winding; magnetoelectric excitation; permanent magnets",,,,,,,,,,,,,,,,,"Chumak, V.

Most previous studies were focused on the static behavior of CSWs and simple beams with CSWs. The calculation of deflection is an important part in the static analysis of structures. However, very few studies have been conducted to investigate the deflection of full PC girders or bridges with CSWs and no simple formulas are available for estimating their deflection under static loads. In addition, experimental work on full-scale bridges or scale bridge models with CSWs is very limited. In this paper, a formula for calculating the deflection of PC box girders with CSWs is derived. The longitudinal displacement function of PC box girders with CSWs, which can consider the shear lag effect and shear deformation of CSWs, is first derived. Based on the longitudinal displacement function, the formula for predicting the deflection of PC box girders with CSWs is derived using the variational principle method. The accuracy of the derived formula is verified against experimental results from a scaled bridge model and the finite element analysis results. Parametric studies are also performed, and the influences of shear lag and shear deformation on the deflection of the box girder with CSWs are investigated by considering different width-to-span ratios and different girder heights. The present study provides an effective and efficient tool for determining the deflection of PC box girders with CSWs. © 2020 Wei Ji et al.",,"Concrete beams and girders; Deflection (structures); Fiber optic sensors; Prestressed concrete; Shear deformation; Shear flow; Steel bridges; Corrugated steel webs; Derived formulae; Longitudinal displacements; Parametric study; Scaled bridge models; Shear lag effects; Static behaviors; Variational principles; Box girder bridges",,,,,,,,,,,,,,,,"Xiao, K., Ashiduka, K., Yoda, T., Sato, K., Sakurada, M., Hidaka, S., Loading tests of Hondani bridge (1998) Bridge and Foundation Engineering, 32 (10), pp. 25-34. , in Japanese; Hassanein, M.F., Kharoob, O.F., Shear buckling behavior of tapered bridge girders with steel corrugated webs (2014) Engineering Structures, 74, pp. 157-169. , 2-s2.0-84901976722; Nie, J.-G., Zhu, L., Tao, M.-X., Tang, L., Shear strength of trapezoidal corrugated steel webs (2013) Journal of Constructional Steel Research, 85, pp. 105-115. , 2-s2.0-84876137779; Gao, L., Liu, J.P., Chen, Y.F., Theoretical and numerical study on the natural frequencies of bridges with corrugated steel webs (2018) Structures, 15, pp. 224-231. , 2-s2.0-85050151691; Chen, Y., Dong, J., Xu, T., Xiao, Y., Jiang, R., Nie, X., The shear-lag effect of composite box girder bridges with corrugated steel webs and trusses (2019) Engineering Structures, 181, pp. 617-628. , 2-s2.0-85058783802; Feng, Y., Jiang, L., Zhou, W., Improved analytical method to investigate the dynamic characteristics of composite box beam with corrugated webs (2020) International Journal of Steel Structures, 20 (1), pp. 194-206. , 2-s2.0-85073986410; Abbas, H.H., Sause, R., Driver, R.G., Simplified analysis of flange transverse bending of corrugated web I-girders under in-plane moment and shear (2007) Engineering Structures, 29 (11), pp. 2816-2824. , 2-s2.0-35449006193; Elgaaly, M., Seshadri, A., Hamilton, R.W., Bending strength of steel beams with corrugated webs (1997) Journal of Structural Engineering, 123 (6), pp. 772-782. , 2-s2.0-0031163320; Kim, K.S., Lee, D.H., Choi, S.M., Choi, Y.H., Jung, S.H., Flexural behavior of prestressed composite beams with corrugated web: Part I.

The vibration signals obtained from Ambient Vibration Testing (AVT) campaigns were processed in order to obtain the modal parameters of the bridge during the two construction stages. Modal parameters experimentally obtained for the first stage were compared with those obtained from Finite Element (FE) models considering different construction loads scenarios. Finally, modal parameters experimentally obtained for the second stage were used to update its corresponding FE model considering two scenarios, before and after the installation of the asphalt pavement. The results presented in this paper demonstrated that a rigorous construction control is needed in order to effectively calibrate FE models during the construction process of segmental bridges. © 2020.

A coupling bridge between the micro-ion reaction system and the macroscopic multi-physical field was constructed by means of the electronic energy distribution function, which revealed the coupling mechanism in the process of corona charge. Moreover, it revealed the transport and accumulation mechanism of charge on the surface of insulating materials. 2D axisymmetric finite element model was built based on the multi-physical field coupling theory. 10 kV negative voltage was applied using a pin-plate electrode structure and polyimide film was taken as insulated surface to simulate the dynamic charge accumulation behaviors in the corona discharge process. The generation, migration and distribution laws of charged ions and electrons in different stages of corona discharge process were given. Charge distribution laws in different stages of charge process of polyimide were given and discussed. When corona discharge reached quasi-stationary state, the total charge number accumulated on the surface was at 10-10 Coulomb order of magnitude, and the drift current was at 10-7 ampere order of magnitude. An experimental platform was set up to test drift current and charge distribution under quasi-stable discharge state. The results show that the simulation results and the experimental data under quasi-stable state are consistent, thus indirectly verifying the correctness of the proposed numerical simulation algorithm and its simulation results. © 2013 IEEE.","Air gaps; charge transfer; finite element methods; surface charging","Charge distribution; Distribution functions; Electric corona; Electric field effects; Numerical methods; Polyimides; Accumulation mechanisms; Axisymmetric finite elements; Charge accumulation; Electronic energy distribution; Experimental platform; Multi-physical fields; Numerical simulation algorithms; Quasi-stationary state; Finite element method",,,,,"National Natural Science Foundation of China, NSFC: 51677009","This work was supported by the National Natural Science Foundation of China under Grant 51677009.",,,,,,,,,,"Mangelsdorf, C.W., Cooke, C.M., Bulk charging of epoxy insulation under DC stress (1980) Proc.

Therefore, this study carried out finite element analysis on the interface friction considering the influence of seasonal temperature and bolt fracture. Through finite element analysis, the simulation of interface friction under seasonal temperature revealed the distribution of temperature-induced interface friction in different areas and locations. Further simulation of fractured bolts revealed the influence of quantity and location of fractured bolts on the redistribution of interface friction. Finally, the interface frictions in the bolted joint were evaluated using limit state equations. The results showed that: 1) the quantity and location of fractured bolts cause obvious redistribution of interface friction in the bolt-fractured areas; 2) the quantity and location of fractured bolts have slight effect on the total interface friction in the whole splice plate; 3) the reduced interface friction in the bolt-fractured areas was transferred to the areas without bolt fracture, producing little change in the total interface friction;4) all the splice plates had abundant safety margin after analysis of their limit state equations. © 2020 The Author(s).

The plating and the flat bar stiffeners consist of mild steel with a certified yield strength. Furthermore, nonlinear Finite Element Analyses (FEA) are performed to simulate the collapse behavior of the box girder specimens in four-point bending.

In this paper, a bearingless PM motor has been proposed for axial blood pump applications. The finite-element method (FEM) is used to predict the electromagnetic characteristics of the designed motor with improved performance. Two topologies are investigated, namely the integral-slot and distributed-windings method and the fractional-slot and double-layer concentrated windings method. Both motors are analyzed and optimized. FEM reveals that, compared with the integral-slot motor, the fractional-slot motor offers significantly enhanced performance, including reduced cogging torque, improved back electromotive force (back EMF), and decreased magnetic flux leakage. Finally, hydraulic experiments have been conducted in a mock-circulation loop to validate the feasibility of the designed motor for an axial blood pump. The results show that the fractional-slot bearingless PM motor can drive the RBP to produce physiological blood flow with reasonable efficiency. © 2013 IEEE.","Blood pump; cogging torque; finite-element analysis; fractional slot; permanent magnet motors","Electric motors; Finite element method; Magnetic leakage; Permanent magnets; Pumps; Torque; Winding; Back electromotive force; Blood pump; Cogging torque; Concentrated winding; Electromagnetic characteristic; Fractional slot; Magnetic flux leakage; Permanent magnet motor; Blood",,,,,"SJCX18_0732; National Natural Science Foundation of China, NSFC: 31600794, 51677082","This work was supported in part by the National Natural Science Foundation under Project 51677082 and Project 31600794 and in part by the Jiangsu Postgraduate Practice and Innovation Program under Grant SJCX18_0732.",,,,,,,,,,"Moazami, N., Fukamachi, F., Kobayashi, M., Axial and centrifugal continuous-ow rotary pumps: A translation from pump mechanics to clinical practice (2013) J Heart Lung Transplantation, 32 (1), pp. 1-11; Soucy, K.G., Koenig, S.C., Sobieski, M.A., Slaughter, M.S., Giridharan, G.A., Fault detection in rotary blood pumps using motor speed response (2013) Asaio J., 59 (4), pp. 410-419. , Jul./Aug; Laruse, J.A., Tamez, D., Ashenuga, M., Reyes, C., Design concepts and principle of operation of the HeartWare ventricular assist system (2010) J.

In the design of these beams, the longitudinal stiffness of the corrugated web is assumed to be negligible and so the moment capacity is derived entirely from the flanges while the shear capacity of the beam is based on the shear strength of the web alone. The advantage of beams with corrugated webs is the increased resistance to shear buckling without the need to weld stiffeners to the web. Although beams with corrugated webs are mainly used to increase the shear capacity, flexural-torsional buckling is also an important failure mode. The flexural-torsional buckling strength very much depends on the torsion and warping constants of the beam. While these section properties can be easily calculated for conventional I beams with flat webs, the computation of these properties for beams with corrugated webs is not so well understood. In this paper, the torsion of beams with trapezoidal corrugated webs is investigated and the torsion and warping constants calculated for different corrugation geometries. A finite element analysis is used to analyse the beams under uniform and non-uniform torsion. The results are compared with the torsion and warping constants for conventional I beams with flat webs.

Such effect is mainly accounted for soil-pile interaction (SPI) driven by the deformation of pile and surrounding soil, and thus it can become significantly obvious due to large soil deformation during a severe earthquake. To capture this characteristic of simply supported bridge structure with pile foundations, a three-dimensional (3D) finite element (FE) model is developed using the computational platform OpenSees considering SPI. A two-span reinforced concrete bridge with a single pier located in multi-layered clay is employed as a test-bed. A variety of seismic responses of this coupled soil-pile-bridge system are systematically investigated. Furthermore, a parametric study is performed to explore the influences of SPI, multidirectional excitation and earthquake characteristic on the seismic responses of soil and structure. The results show that: (1) the seismic response of the bridge structure is significantly affected by its longitudinal and transversal different configuration; (2) the fixed-base support type noticeably influences the seismic response of bridge structure and (3) the direction and characteristic of base input earthquake motion greatly influence the seismic response of the bridge-soil system. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.","Bridges; finite element method; pile foundations; seismic analysis; soil lateral displacements; soil-pile interaction; soil-structure interaction","Bridges; Deformation; Earthquakes; Finite element method; Pile foundations; Reinforced concrete; Seismic response; Soil structure interactions; Soils; Computational platforms; Lateral displacements; Pile supported structures; Seismic analysis; Seismic response analysis; Simply supported bridge; Soil-pile interactions; Three dimensional finite elements; Piles",,,,,"National Natural Science Foundation of China, NSFC: 51808307, 51878235; Natural Science Foundation of Shandong Province: ZR2017QEE007; Taishan Scholar Project of Shandong Province: 2015-212; National Basic Research Program of China (973 Program): 2016YFE0205100","This research was financially supported by the National Natural Science Foundation of China (51808307 and 51878235), the National Key Research and Development Program of China (2016YFE0205100), the Special Project Fund of Taishan Scholars of Shandong Province, China (2015-212) and the Shandong Provincial Natural Science Foundation, China (ZR2017QEE007).",,,,,,,,,,"Alfach, M., Influence of soil plasticity on the seismic performance of pile foundation-a 3D numerical analysis (2012) Jordan Journal of Civil Engineering, 6 (4), pp. 394-409; Audemard, M.F.A., Gómez, J.C., Tavera, H.J., Orihuela, G.N., Soil liquefaction during the Arequipa Mw 8.4, June 23, 2001 earthquake, southern coastal Peru (2005) Engineering Geology, 78 (3), pp. 237-255; Aviram, A., Mackie, K.R., Stojadinovic, B., Effect of abutment modeling on the seismic response of bridge structures (2008) Earthquake Engineering and Engineering Vibration, 7 (4), pp. 395-402; Aygün, B., Dueñas-Osorio, L., Padgett, J.E., DesRoches, R., Efficient longitudinal seismic fragility assessment of a multispan continuous steel bridge on liquefiable soils (2011) Journal of Bridge Engineering, 16 (1), pp. 93-107; Badry, P., Satyam, N., DSSI for pile supported asymmetrical buildings: A review (2014) Civil Engineering and Urban Planning: An International Journal, 1 (2-3), pp. 45-63; Boulanger, R.W., Curras, C.J., Kutter, B.L., Wilson, D.W., Abghari, A., Seismic soil-pile-structure interaction experiments and analyses (1999) Journal of Geotechnical and Geoenvironmental Engineering, 125 (9), pp. 750-759; Boulanger, R.W., Idriss, I.M., Mejia, L.H., (1995) Investigation and evaluation of liquefaction related ground displacements at Moss Landing during the 1989 Loma Prieta Earthquake, , Davis, CA: Center for Geotechnical Modeling, Department of Civil & Environmental Engineering, University of California; Bowen, H., Cubrinovski, M., Effective stress analysis of piles in liquefiable soil: A case study of a bridge foundation (2008) Bulletin of the New Zealand Society for Earthquake Engineering, 41 (4), pp. 247-262; Casciati, S., Borja, R.I., Dynamic FE analysis of South Memnon Colossus including 3D soil-foundation-structure interaction (2004) Computers & Structures, 82 (20), pp. 1719-1736; Dezi, F., Carbonari, S., Leoni, G., Seismic response of bridges on pile foundations considering soil-structure interaction (2008) International fib Symposium 2008, pp. 891-897. , Amsterdam; Dou, H., Byrne, P.M., Dynamic response of single piles and soil-pile interaction (1996) Canadian Geotechnical Journal, 33 (1), pp. 80-96; Elgamal, A., Yan, L., Yang, Z., Conte, J.P., Three-dimensional seismic response of Humboldt Bay bridge-foundation-ground system (2008) Journal of Structural Engineering, 134 (7), pp. 1165-1176; Elnashai, A.S., Kwon, O.S., Distributed analytical modeling of bridges with soil-foundation-structure interaction (2007) 1st US-Italy Seismic Bridge Workshop, , Buffalo, New York:, &,.

Because of the limited space available for the car, the composite pressure vessel (Type II) has been applied to the CNG vehicles to reach large capacity and weight lightening vehicles. High pressure vessel (Type II) is composed of a composite layer and a metal liner. The metal liner is formed by the deep drawing and ironing (D.D.I.) process, which is a complex process of deep drawing and ironing. The cylinder part is reinforced by composite layer wrapped through the filament winding process and is bonded to the liner by the curing process. In this study, an integrated design method was presented by establishing the techniques for FE analysis of entire processes (D.D.I., filament winding and curing processes) to manufacture the CNG composite pressure vessel (Type II). Dimensions of the dies and the punches of the 1st (cup drawing), 2nd (redrawing-ironing 1-ironing 2) and 3rd (redrawing-ironing) stages were calculated theoretically, and shape of tractrix die to be satisfied with the minimum forming load was suggested for life improvement and manufacturing costs in the D.D.I. process. Thickness of the composite material was determined in the filament winding process, finally, conditions of the curing process (number of heating stage, curing temperature, heating rate and time) were proposed to reinforce adhesive strength between the composite layers. © 2019, The Author(s).","Curing process; D.D.I; FEM; Filament winding; Pressure vessel (Type II)","Adhesives; Automobile manufacture; Bridge decks; Compressed natural gas; Curing; Deep drawing; Design; Energy policy; Finite element method; Fossil fuels; Natural gas vehicles; Pressure vessels; Composite pressure vessels; Compressed natural gasses (CNG); Conventional gasoline; Curing process; D.D.I; Deep drawing and ironing; Filament winding process; Type II; Filament winding",,,,,"2019R1F1A1058521; M.S.I.

A vehicle model is presented, and the dynamic load on the bridge is quantified based on bridge road roughness. The vibration of a river bridge under a moving vehicle is recorded and analyzed. The Fourier spectrum of the bridge response due to vehicle loading exhibits complicated cluster bands in addition to multiple peaks, some of which are correlated with the bridge natural modes characterized by finite element method analysis and free decay testing, and some of which are correlated with the vehicle dynamic load spectrum. To characterize the unidentified narrow band in the bridge response spectrum, the Lyapunov exponent of the response is estimated, which is found to be a positive value indicating the nonlinear properties of the bridge’s large response under vehicle loading. This finding correlates with the bridge inspection, which shows that some supporting roller bearings do not properly contact the superstructure of the bridge. To elaborate this phenomenon, a model of beam with nonideal supporting condition is analyzed, and a narrow band spectrum is characterized using He’s variational-iteration method. This research offers insight to using the vehicle–bridge interaction to monitor the health status of a bridge by using nonlinear properties, as well as linear properties. © The Author(s) 2018.","bridge dynamics; bridge–vehicle interactions; nonlinear dynamics; Vehicle dynamical modeling","Bridges; Condition monitoring; Dynamic loads; Dynamics; Fourier series; Iterative methods; Lyapunov methods; Nonlinear analysis; Roller bearings; Spectrum analysis; Vehicles; Bridge dynamics; Dynamical model; Finite element method analysis; Nonlinear properties; Nonlinear vibration analysis; Supporting conditions; Variational iteration method; Vehicle interactions; Vibration analysis",,,,,"University of Alaska Anchorage, UAA","The authors wish to acknowledge the support of Nanjing University of Science and Technology, University of Alaska Fairbanks, University of Alaska Anchorage, and Alaska Native Science and Engineering Program.",,,,,,,,,,"Bao, T., Liu, Z., Vibration‐based bridge scour detection: a review (2017) Struct Control Health Monit, 24. , e1937; Zhu, X.Q., Law, S.S., Recent developments in inverse problems of vehicle–bridge interaction dynamics (2016) J Civil Struct Health Monit, 6, pp. 107-128; Malekjafarian, A., Mcgetrick, P.J., Obrien, E.J., A review of indirect bridge monitoring using passing vehicles (2015) Shock Vib, 2015, p. 286139; Yang, Y.B., Lin, C.W., Yau, J.D., Extracting bridge frequencies from the dynamic response of a passing vehicle (2004) J Sound Vib, 272, pp. 471-493; Lin, C.W., Yang, Y.B., Use of a passing vehicle to scan the fundamental bridge frequencies: an experimental verification (2005) Eng Struct, 27, pp. 1865-1878; González, A., Covián, E., Madera, J., Determination of bridge natural frequencies using a moving vehicle instrumented with accelerometers and a geographical positioning system.

Based on basic principle of pseudo excitation method (PEM), an optimized algorithm was proposed to be SPEM. The effects of the uncertainties of structure and excitations could be considered through SPEM, thus directly acquiring the whole sampling results of random vibration of uncertain structural system. To reduce the cost of computing the total number of required finite element analysis simulations, RSM was adopted to hold calculated sampling results to gain the probability density function (PDF) of random vibration. The proposed method can consider both the effects of random characteristics of power spectrum of random excitations and the uncertainties of target system. Neverthless, Since the proposed method is based on the pseudo excitation method, the SPEM-RSM can handle the stochastic vibration analysis of determine and uncertain structure. In order to verify the accuracy and efficiency of proposed method, taking a single degree of freedom linear uncertain oscillator and a pier construction as two verification cases, the PDF of responses computed by the hybrid method was verified by Monte Carlo method (MCM), and the efficiency of the proposed method was presented. Then, stochastic responses of the railway continuous bridge subjected to earthquake were calculated, several uncertainties are involved in the computation. In addition, sensitivity analysis was solved for uncertain parameters. © 2019","Random vibration; Response surface method; Sensitivity; Stochastic pseudo excitation method; Uncertainties","Degrees of freedom (mechanics); Earthquakes; Efficiency; Piers; Probability density function; Sensitivity analysis; Spectral density; Stochastic systems; Surface properties; Uncertainty analysis; Vibration analysis; Pseudo excitation methods; Random vibrations; Response surface method; Sensitivity; Uncertainties; Monte Carlo methods; algorithm; bridge; earthquake engineering; response surface methodology; sensitivity analysis; stochasticity; uncertainty analysis; vibration",,,,,"National Natural Science Foundation of China, NSFC: 51908076; Guizhou Science and Technology Department: [2016]2047","The writers are grateful for the financial supports from the National Natural Science Foundation of China ( 51908076 ), and the GuiZhou Province Science and Technology Department Funded Project ( [2016]2047 ).",,,,,,,,,,"Kareem, A., Sun, W.J., Dynamic response of structures with uncertain damping (1990) Eng Struct, 12, pp. 2-8; Marano, G.C., Morrone, E., Quaranta, G., Analysis of randomly vibrating structures under hybrid uncertainty (2009) Eng Struct, 31, pp. 2677-2686; Huang, M.F., Chan, C.M., Lou, W.J., Optimal performance-based design of wind sensitive tall buildings considering uncertainties (2012) Comput Struct, 98-99, pp. 7-16; Xu, Y., Bai, G., Random buckling bearing capacity of super-large cooling towers considering stochastic material properties and wind loads (2013) Probabilistic Eng Mech, 33, pp. 18-25; Ye, X.W., Xi, P.S., Su, Y.H., Chen, B., Han, J.P., Stochastic characterization of wind field characteristics of an arch bridge instrumented with structural health monitoring system (2018) Struct Saf, 71, pp. 47-56; Donghuang, Y., Yuan, L., Naiwei, L., Ming, Y., Beer, M., Fatigue stress spectra and reliability evaluation of short- to medium-span bridges under stochastic and dynamic traffic loads (2017) J Bridge Eng, 22, pp. 1-11; Mangalathu, S., Jeon, J.S., Desroches, R., Critical uncertainty parameters influencing seismic performance of bridges using Lasso regression (2018) Earthq Eng Struct Dyn, 47, pp. 784-801; Omrani, R., Mobasher, B., Sheikhakbari, S., Zareian, F., Taciroglu, E., Variability in the predicted seismic performance of a typical seat-type California bridge due to epistemic uncertainties in its abutment backfill and shear-key models (2017) Eng Struct, 148, pp. 718-738; Mannini, C., Bartoli, G., Aerodynamic uncertainty propagation in bridge flutter analysis (2015) Struct Saf, 52, pp. 29-39; Caprani, C.C., Application of the pseudo-excitation method to assessment of walking variability on footbridge vibration (2014) Comput Struct, 132, pp. 43-54; Rosa, S.D., Franco, F., Ciappi, E., A simplified method for the analysis of the stochastic response in discrete coordinates (2015) J Sound Vib, 339, pp. 359-375; Wei, D., Rahman, S., A multi-point univariate decomposition method for structural reliability analysis (2010) Int J Press Vessel Pip, 87, pp. 220-229; Zhang, X., Pandey, M.D., Structural reliability analysis based on the concepts of entropy, fractional moment and dimensional reduction method (2013) Struct Saf, 43, pp. 28-40; Balomenos, G.P.P., M.D, Finite element reliability and sensitivity analysis of structures using the multiplicative dimensional reduction method (2016) Struct Infrastruct Eng, 12, pp. 1-13; Rubinstein, R.Y., Simulation and the Monte Carlo method, NY (2008), John Wiley & Sons Publication New York; Frangopol, D.M., Probability concepts in engineering: emphasis on applications to civil and environmental engineering (2008) Struct Infrastruct Eng, 4, pp. 413-414; Sudret, B., Der Kiureghian, A., Comparison of finite element reliability methods (2002), p. 337. , Elsevier Science B.V.

Bancroft St., MS307, Toledo, OH  43606, United States","Deep pier caps possess additional shear strength due to the formation of the strut action which cannot be captured by the traditional sectional method. The strut-and-tie method (STM) is a suitable method for capturing the deep beam action. The application of the STM, however, has many challenges including creating and optimizing a valid truss model, performing an indeterminate truss analysis, calculation of nodal and elemental stress limits, etc. The objective of this study is to explore innovative strategies to reduce the complexity of the STM by developing a strut-and-tie methodology to rapidly and accurately predict the shear capacities of deep pier caps. A graphical solution algorithm and associated computer code is developed to generate and analyze efficient strut-and-tie models while intuitively educating engineers in the correct use of the methodology. The accuracy of the methodology is assessed by modeling eight existing bridge pier caps with a general-purpose strut-and-tie method. In addition, nonlinear finite element analyses of the same pier caps are performed for an in-depth investigation and comparisons of the governing behaviors, strengths, and modes of failure with those obtained from the proposed methodology. Although not valid for deep beams, the sectional method calculations are performed to demonstrate the consequences of using it. The relationship between the shear span-to-depth ratio and the shear strength predictions from all three methods are compared for twenty-one regions. The proposed methodology has general applicability for modeling deep pier caps and is shown to provide similar modeling time and effort to the sectional method with accuracies comparable to those obtained from the nonlinear finite element analysis. © 2019 Elsevier Ltd","Bent cap; Deep beam; Load rating; Nonlinear analysis; Pier cap; Rehabilitation; Sectional method; Shear capacity; Strengthening; Strut and tie","Bridge piers; Forecasting; Nonlinear analysis; Patient rehabilitation; Piers; Strengthening (metal); Trusses; Bent caps; Deep beam; Load ratings; Pier cap; Sectional methods; Shear capacity; Strut-and-tie; Finite element method; finite element method; loading; prediction; shear strength; structural component",,,,,"Ohio Department of Transportation, ODOT","The authors would like to thank the Ohio Department of Transportation, United States, (ODOT) for funding and supporting this research.

However, the mechanism of the compression therapy for chronic venous insufficiency is still unclear. To elaborate the mechanism of compression therapy, in recent years, the computational modelling technique, especially the finite element modelling method, has been widely used. However, there are still many unclear issues regarding the finite element modelling of compression therapy, for example, the selection of appropriate material models, the validation of the finite element predictions, the post-processing of the results. To shed light on these unclear issues, this study provides a state-of-the-art review on the application of finite element modelling technique in the compression therapy for chronic venous insufficiency. The aims of the present study are as follows: (1) to provide guidance on the application of the finite element technique in healthcare and relevant fields, (2) to enhance the understanding of the mechanism of compression therapy and (3) to foster the collaborations among different disciplines. To achieve these aims, the following parts are reviewed: (1) the background on chronic venous insufficiency and the computational modelling approach, (2) the acquisition of medical images and the procedure for generating the finite element model, (3) the definition of material models in the finite element model, (4) the methods for validating the finite element predictions, (5) the post-processing of the finite element results and (6) future challenges in the finite element modelling of compression therapy. © IMechE 2019.","chronic venous insufficiency;

The vibration differential equations and natural boundary conditions of TWBBs are deduced. On the basis of eight examples of TWBBs with different boundary conditions and span–width ratios, analytical results of this paper are compared with those of the ANSYS finite element method. Both results are in good agreement with each other, and the validity of the calculation method is verified. The effects of higher order shear deformations and shear lag on natural vibration characteristics of TWBBs are analyzed. And some meaningful conclusions are drawn: This theory shows the capability to accurately describe both higher order deformations and shear lag; when the span–width ratio is small, neglecting higher order web deformations will produce a large calculation error; under the action of shear lag, the natural vibration frequency of TWBBs decreases greatly, which cannot be neglected; and both the high-order shear deformations and shear lag effect increase with increasing mode order and increase with decreasing span–width ratio. © 2019 John Wiley & Sons, Ltd.","Hamilton's principle; higher order shear deformations; natural vibration; shear lag effect; thin-walled box beams","Boundary conditions; Box girder bridges; Fiber optic sensors; Shear deformation; Shear flow; Thin walled structures; Box beam; Hamilton's principle; Higher order shear deformation; Natural vibration; Shear lag effects; Vibration analysis",,,,,"National Natural Science Foundation of China, NSFC: 51408449, 51778630; Fundamental Research Funds for Central Universities of the Central South University: 2018zzts189","The research described in this paper was financially supported by the National Natural Science Foundation of China (51408449 and 51778630) and the Fundamental Research Funds for the Central Universities of Central South University (2018zzts189).",,,,,,,,,,"Liu, Y.-C., Lday, M., (2006) Int.

Various influential factors such as element size, constitutive relations, second order effects of structure and membrane effects in buckling area were discussed to achieve a better validation with experimental data. As load increasing, the plastic strain in the U-rib near the end stiffener increases gradually under the influence of initial imperfections and stress concentration. Local buckling occurs after yielding of the whole section. With the refined model, the sensitivity of stiffened structure to the residual stresses and imperfections are investigated, and parametric studies on the material properties, geometric dimensions are conducted. The results show that the initial imperfections have a major influence on the ultimate capacity while the residual compressive stresses govern the elastic capacity and the ductility. Proper values of the imperfections and residual stresses are suggested for FE stiffened plate simulations. HPS stiffened plates with short length is more sensitive to initial imperfections. The effects of length, thickness and spacing are similar to the ordinary steel plates. Both equations in American and Chinese standards are used to evaluate the ultimate capacity of stiffened HPS plates, and formulas in AASHTO provide a more accurate estimate on capacity and failure mode, while Chinese specification is more conservative comparatively. © 2019, Korean Society of Steel Construction.","Buckling; Finite element model; High strength steel; Imperfections; Residual stresses; Stiffened plates","Buckling; Defects; Finite element method; High strength steel; Microalloyed steel; Residual stresses; Steel bridges; Compressive behavior; Constitutive relations; High performance steel; Initial imperfection; Residual compressive stress; Stiffened plate; Three dimensional finite elements; Validation with experimental data; Plates (structural components)",,,,,"Fundamental Research Funds for the Central Universities: 2015B21314","The research reported herein has been conducted as part of the research projects granted by the Fundamental Research Funds for the Central Universities (No. 2015B21314).",,,,,,,,,,"(2010) LRFD-Bridge design specifications, , AASHTO, Washington, DC; (1963) Design Manual for Orthotropic Steel Plate Deck Bridges, , New York; (2015) Release 16.0.

A typical bearing consists of natural rubber sheets and bonded to steel plates. For an application of using rubber bearings, numerous isolated buildings have been constructed to resist an earthquake across the countries which experience earthquakes over decades. Another application might be used in the bridge structures of railways and highways, in order to suppress vibrations and dynamic actions. The key idea is to use rubber isolators attached beneath the superstructures for attenuating the damage potential of seismic responses. This means that the rubber provides the isolators flexible in the horizontal direction and the steel makes them strong in the vertical direction. Anyways, most bearings are made of natural rubber or synthetic compound. These materials are costly and cannot be durable over time. This paper aims to develop a new design of bearing using recycled materials and fibre reinforcement. The concept is to design two models using the finite element method (FEM) as a square and circular shape for the investigation into the static and dynamic behaviour. Through, the finite element method will be conducted to evaluate structural response and effectiveness of the novel low-cost bearing. Bearing models from the analytical method based on the theory are verified by the FEM. The overall results show that the fibre square model is less effective than the fibre circular model due to the different shape factors, S. The outcome of this project will help to enable more eco-friendly bearing materials for structural, highway and railway engineers. However, a further study of designing recycled rubber bearings with the fibre-reinforced polymer should be carried out by experimental tests. The study should be also compared with the performance between the fibre and steel bearing model, in order to verify the models created by FEA more effectively. © Published under licence by IOP Publishing Ltd.",,"Bearings (structural); Earthquakes; Fiber reinforced plastics; Finite element method; Memory architecture; Nonmetallic bearings; Railroad transportation; Railroads; Recycling; Reinforcement; Rubber; Steel fibers; Synthetic rubber; Urban planning; Fibre reinforced composites; Fibre reinforced polymers; Fibre reinforcements; Isolated buildings; Static and dynamic behaviours; Structural response; Suppress vibration; Synthetic compounds; Structural design",,,,,"University of Exeter; European Commission, EC: 730849, Shift2Rail","Authors would like to thank the technical staff at University of Exeter for their kind support, in order to allow the use of Abaqus FEA and support to complete the analysis.

However, the load-carrying capacity of concrete slabs can be limited by the shear capacity and the redistribution of shear forces when subjected to high-intensity loads such as tire pressure from heavy vehicles. In this paper, an optimised layer model is presented which include limitations on both shear and bending. The layer model is based on a sandwich model, which provides a simple way to determine a safe stress distribution for reinforced concrete slabs with shear reinforcement subjected to shear and bending. The yield criteria in the layer model are formulated as second-order cones which enables an efficient implementation in finite element limit analysis where general convex optimisation algorithms are used. The interaction of section forces is investigated for different combinations of shear forces, moments and torsion. The optimised layer model is used, in combination with finite element limit analysis, to evaluate concrete slabs subjected to different load configurations. The results show that the layer model performs very well with finite element limit analysis and it is possible to determine a safe distribution of shear forces, moments and torsion very efficiently. However, the model cannot handle local effects such as punching shear and concentrated loads near the support. © 2019 Elsevier Ltd","Concrete slabs; FELA; Layer model; Limit analysis; Shear-moment interaction; Strength-assessment; Ultimate capacity","Columns (structural); Concrete slabs; Convex optimization; Load limits; Loads (forces); Reinforced concrete; Shear flow; Torsional stress; FELA; Layer model; Limit analysis; Shear-moment interaction; Strength assessment; Ultimate capacity; Finite element method; assessment method; bearing capacity; concrete structure; finite element method; limit analysis; reinforcement; shear strength; shear stress",,,,,"5190-00036B; Innovationsfonden","The work described in this paper was financially supported by COWIfonden , Innovation Fund Denmark (Grant No. 5190-00036B ) and the Danish Road Directorate .","The work described in this paper was financially supported by COWIfonden, Innovation Fund Denmark (Grant No. 5190-00036B) and the Danish Road Directorate.",,,,,,,,,"Johansen, K.W., Brudlineteorier (English translation: Yield Line Theory) (1943) Gjellerups Forlag, 1943; Hillerborg, A., (1974), Strip method of design, no.

The various design methods of the multi-layer IPMSM have been presented, but the irreversible demagnetization is not considered during the design of the motor. In this paper, the multi-layer IPMSM is designed considering the irreversible demagnetization during the design. Because the occurrence of the local irreversible demagnetization can be confirmed by finite element analysis (FEA), the design of the motor proceeds using the FEA. The PM shape, the ratio of the PM thickness and core thickness, the number of PM layers, the pole-angle, the number of bridges, and the thickness of bridges are determined considering the mechanical and electrical characteristics. Improved design to expand the satisfactory area of the target power and reduce the irreversible demagnetization is performed. © 2019 IEEE.","Demagnetization ratio; Ferrite permanent magnet; High-speed multi-layer interior permanent magnet synchronous motor; Irreversible demagnetization; Mechanical stability",,,,,,,,,,,,,,,,,"Jung, Y., Lim, M., Yoon, M., Jeong, J., Hong, J., Torque ripple reduction of IPMSM applying asymmetric rotor shape under certain load condition (2018) IEEE Trans.

The finite-element method is adopted to explore the structural behaviour of a bridge affected by shrinkage and creep of the concrete stiffening girder. The results show that shrinkage and creep of the concrete stiffening girder have a major effect on the mechanical behaviour of the side towers and stiffening girder. A new main cable system consisting of a prefabricated parallel wire strand (PPWS) cable with a polyethylene jacket and cold-cast anchorage is proposed to allow the main cables to be tensioned and the bridge cable force to be adjusted at any time. The experimental results of the PPWS cable show that the design and manufacture of the largest cable in China are safe and reliable. Moreover, the numerical simulation results for a new cable clamp connecting two main cables to a single hanger indicate that its design is reasonable. Furthermore, the anti-corrosive properties of the special cable system are investigated.

The application of precast concrete deck to steel-concrete composite bridges can improve the strength of decks and reduce the shrinkage and creep effect on the long-term behavior of structures. How to ensure the connection between steel girders and concrete deck directly influences the composite behavior between steel girder and precast concrete deck as well as the behavior of the structure system. Compared with traditional multi-I girder systems, a twin-I girder composite bridge system is more simplified but may lead to additional requirements on the shear studs connecting steel girders and decks due to the larger girder spacing. Up to date, only very limited quantity of researches has been conducted regarding the behavior of shear studs on twin-I girder bridge systems. One convenient way for steel composite bridge system is to cast concrete deck in place with shear studs uniformly-distributed along the span direction. For steel composite bridge system using precast concrete deck, voids are included in the precast concrete deck segments, and they are casted with cast-in-place concrete after the concrete segments are erected. In this paper, several sets of push-out tests are conducted, which are used to investigate the heavier of shear studs within the voids in the precast concrete deck. The test data are analyzed and compared with those from finite element models. A simplified shear stud model is proposed using a beam element instead of solid elements. It is used in the finite element model analyses of the twin-I girder composite bridge system to relieve the computational efforts of the shear studs. Additionally, a parametric study is developed to find the effects of void size, void spacing, and shear stud diameter and spacing. Finally, the recommendations are given for the design of precast deck using void for twin I-girder bridge systems.

In highway bridges, tapered columns are usually used to reduce the amount of moments that are transferred from the column base to the foundation. This paper studies slender RC columns with a linear variation in the columns’ cross section in both the principal directions of the cross section. Two slenderness ratios of 70 and 40 have been investigated in this study for RC tapered columns. Computational analysis, using the finite element (FE) method, is conducted in this study after the calibration of the reference FE models with tests that were conducted by other researches in Jenkins (Improving the design of slender, concrete columns. Doctoral dissertation, Purdue University, West Lafayette, 2015). These FE models were extended to account for different degrees of column tapering. The paper found that a minor tapering of the column (where the tapering ratio is greater than 150) is just an esthetic feature and it does not contribute to the buckling load of RC columns. In case of slender columns with a slenderness ratio of 40, the increase in the tapering of the column causes a slight increase in the buckling load of roughly 15%, as compared with non-tapered columns that have the same slenderness ratio. On the other hand, the increase in the buckling load of columns that have a slenderness ratio of 70 is about 45%. Analytical solutions based on the eigenvalue problem have also been presented to estimate the buckling load of a variety of tapering ratios. © 2019, Iran University of Science and Technology.","Buckling load; Finite element; Slender columns; Tapered columns","Buckling; Columns (structural); Concrete construction; Eigenvalues and eigenfunctions; Finite element method; Buckling loads; Computational analysis; Doctoral dissertations; Nonlinear buckling analysis; Principal directions; Slender columns; Slender reinforced concrete columns; Tapered columns; Reinforced concrete",,,,,,,,,,,,,,,,"MacGregor, J.G., Breen, J.E., Design of slender concrete columns (1970) J Proc, 67 (1), pp. 6-28; Macgregor, J.G., Barter, S.L., Long eccentrically loaded concrete columns bent in double curvature (1966) Symposium on Reinforced Concrete columns—ACI Special Publication, 13 (1), pp. 139-156; Jenkins, R.W., (2015) Improving the Design of Slender, Concrete Columns, , Doctoral dissertation, Purdue University, West Lafayette; (2014) Building code requirements for structural concrete and commentary, , ACI 318-14, Farmington Hills; Mirza, S., Flexural stiffness of rectangular reinforced concrete columns (1990) ACI Struct J, 87 (4), pp. 425-435; Khuntia, M., Ghosh, S.K., Flexural stiffness of reinforced concrete columns and beams: experimental verification (2004) Struct J, 101 (3), pp. 364-374; Lloyd, N.A., Rangan, B.V., (1995) High Strength Concrete Columns under Eccentric Compression, , In, Doctoral dissertation, School of Civil Engineering Curtin University of Technology, Perth, Western Australia; Alavi, A., Rahgozar, R., A simple mathematical method for optimal preliminary design of tall buildings with peak lateral deflection constraint (2018) Int J Civil Eng, 6 (1), pp. 1-8; Hu, H.T., Huang, C.S., Wu, M.H., Wu, Y.M., Nonlinear analysis of axially loaded concrete-filled tube columns with confinement effect (2003) J Struct Eng, 129 (10), pp. 1322-1329; Takiguchi, K., An investigation into the behavior and strength of reinforced concrete columns strengthened with ferrocement jackets (2003) Cement Concrete Composites, 25 (2), pp. 233-242; Ozcan, O., Binici, B., Ozcebe, G., Improving seismic performance of deficient reinforced concrete columns using carbon fiber-reinforced polymers (2008) Eng Struct, 30 (6), pp. 1632-1646; Fitzwilliam, J., Bisby, L.A., Slenderness effects on circular CFRP confined reinforced concrete columns (2010) J Composit Construct, 14 (3), pp. 280-288; Marques, L., Da Silva, L.S., Rebelo, C., Rayleigh-Ritz procedure for determination of the critical load of tapered columns (2014) Steel Comp Struct, 16 (1), pp. 45-58; Li, Q.S., A stability of non-uniform columns under the combined action of concentrated follower forces and variably distributed loads (2008) J Construct Steel Res, 64 (3), pp. 367-376; Maiorana, E., Pellegrino, C., Linear buckling analysis of welded girder webs with variable thickness (2011) Steel Compos Struct Int J, 11 (6), pp. 505-524; Ermopoulos, J., Equivalent buckling length of non-uniform members (1997) J Construct Steel Res, 42 (2), pp. 141-158; Yossif, W.V., Elastic critical load of tapered members (2008) J Eng Dev, 12 (1), pp. 148-160; Coskun, S.B., Öztürk, B., Elastic stability analysis of euler columns using analytical approximate techniques (2012) Adv Comput Stabil Anal, 6 (1), pp. 115-132; Iremonger, M.J., Finite difference buckling analysis of non-uniform columns (1980) Comput Struct, 12 (5), pp. 741-748; Head, M.C., Aristizabal-Ochoa, J.D., Analysis of prismatic and linearly tapered reinforced concrete columns (1987) J Struct Eng, 113 (3), pp. 575-589; Gallagher, R.H., Lee, C.H., Matrix dynamic and instability analysis with non-uniform elements (1970) Int J Numer Meth Eng, 2 (2), pp. 265-275; (2011) Analysis user’s Manual Online Documentation, , Dassault Systèmes Simulia Corp, Providence; Chang, G.A., Mander, J.B., (1994) Seismic Energy Based Fatigue Damage Analysis of Bridge Columns: Part 1—evaluation of Seismic Capacity, , NCEER Technical Report No. NCEER-94-0006, State University of New York, Buffalo; (2012), The MathWorks, Inc, Natick","Alkloub, A.; Department of Civil Engineering, Queen Rania St, Jordan; email: a.kloub@ju.edu.jo",,,"Springer International Publishing",,,,,17350522,,,,"English","Int.

Hence, this paper presents a dual-layer substrate sandwiched bridge piezoelectric transducer which converts the mechanical energy into useful electricity to achieve a reliable power source. A dual-layer of thin substrate is added in order to shift away and reduce the stress concentration in the piezoelectric material as high stress concentration will lead to a mechanical failure of transducer such as cracking of piezoelectric plate or distorted end-cap structure. A coupled piezoelectric-circuit finite element model (CPC-FEM) was developed to predict the electric power output and stress concentration of the transducer. The optimum end-cap thickness and suitable material used are determined first within the failure stress criteria. Then, the CPC-FEM was used to study the effect of presence of substrate in reducing the stress concentration and the efficiency of substrate in increasing the load capacity as well as electric power output. The FEA results show that the voltage produced by the transducer is about 132 V with 0.4 mm thickness of titanium alloy end-caps and 0.3 mm stainless steel substrates, which could result in 0.18 mJ of electrical energy and about 3.56 mW potential power output at 20 Hz under the loading pressure of 0.7 MPa. © 2019 IEEE.","Asphalt pavement; Bridge structure; Dual-layer substrate; Energy harvesting; Piezoelectric transducer","Asphalt mixtures; Asphalt pavements; Energy harvesting; Failure (mechanical); Finite element method; Nanosensors; Nanotechnology; Outages; Piezoelectricity; Stress concentration; Substrates; Thermoelectric power; Titanium alloys; Transducers; Vibrations (mechanical); Wireless sensor networks; Bridge structures; Dual-layer substrates; Electric power output; High stress concentration; Mechanical energies; Mechanical failures; Piezoelectric plate; Stainless steel substrates; Piezoelectric transducers",,,,,"Universiti Malaya: GPF081A-2018","ACKNOWLEDGMENT This study was supported by University of Malaya Research University Grant (RU Faculty) under grant no.

Two constituent metals comprising the multilayered configurations were Al 6063-T6 and IS 1570. Multiple stack sequences of trilayered and bilayered configurations were evaluated at three different sets of strain rates, namely, 500, 800, and 1000 s-1. The experiments revealed that even with the same constituent volume fraction, a change in the stacking sequence alters the overall dynamic constitutive response. This change becomes more evident, especially in the plastic zone. The finite element analysis was performed using abaqus/explicit. A three-dimensional (3D) model of the SHPB apparatus used in the experiments was generated and meshed using the hexahedral brick elements. Dissimilar material interfaces were assigned different dynamic coefficients of friction. The fundamental elastic one-dimensional (1D) wave theory was then utilized to evaluate the stress-strain response from the nodal strain histories of the bars. Predictions from the finite element simulations along with the experimental results are also presented in this study. For most cases, finite element predictions match well with the experiments. © 2019 by ASME.","constitutive behavior; Dynamic compression; finite element simulations; heterostacked structures; high strain rate","3D modeling; ABAQUS; Bridge decks; Finite element method; Friction; Constitutive behaviors; Dynamic compression; Finite element simulations; Finite-element predictions; High strain rates; Multilayered configurations; Split Hopkinson pressure bars; Three dimensional (3-D) modeling; Strain rate",,,,,,,,,,,,,,,,"Lundberg, P., Renström, R., Lundberg, B., Impact of Metallic Projectiles on Ceramic Targets: Transition between Interface Defeat and Penetration (2000) Int.

The bridge consists of two major cables anchored at their ends and a series of pin-ended hangers attached to the cables supporting a lightweight deck whose stiffness can be neglected. Assuming the hangers can be replaced by a continuous inextensible diaphragm, it will be shown that under the action of lateral loads, the diaphragm exerts on the cables a restitution force that can be assimilated to a reaction density. Writing the equations of static equilibrium of the cables under these conditions leads to a Fredholm integral equation whose solution is actually the unknown reaction density. The solution of the equation obtained through numerical integration was found to be in good agreement with the finite element method across different configurations of lateral loads. The method was subsequently used to carry a parametric study on the effects of some important parameters such as the initial pre-stress adjustment in the deck cable, and self-weight on the stability of the bridge to lateral loads. The method is robust yet simple to use; a detailed example of its implementation is given as the Appendix. © 2019","Bi-concave cable truss; Continuous inextensible diaphragm; Finite element; Fredholm integral equation; Reaction density","Bridge cables; Diaphragms; Finite element method; Numerical methods; Trusses; Cable truss; Fredholm integral equations; Initial prestress; Lightweight deck; Numerical integrations; Simplified method; Static equilibrium; Statically indeterminate structure; Integral equations; bridge; finite element method; force; loading; parameterization; stiffness; stress",,,,,,,,,,,,,,,,"Fuller, R.B., (1962), Tensile-integrity structures.

The capacity in shear is especially critical as it was not considered in design recommendations before 1976. Therefore, experiments on a 1:2 scale model of a transversely prestressed concrete bridge deck cast between concrete girders were carried out to investigate the bearing (punching shear) capacity. The scale was selected based on the space available in the laboratory and the expected failure loads that would have to be applied. Also, a three-dimensional, solid, nonlinear finite element model was developed in the Finite Element Analysis software package TNO DIANA to study the structural behavior of deck slabs and is the focus of this paper. The results of the experimental and numerical analyses leads to the conclusion that existing bridges still have significant residual strength due to the presence of transverse prestressing and the membrane forces, and nonlinear finite element models can predict the load carrying capacity quite accurately. © 2019 fib.

However, the evolution of mineral density in the extant and new bone after nucleotomy and fixation techniques has to date not been investigated in detail. The main goal of this study is to determine possible mechanisms that may trigger the bone remodelling and formation processes. With that purpose, a finite element model of the L4–L5 spinal segment was used. Bone mineral density (BMD), new tissue composition, and endplate deflection were determined as indicators of lumbar fusion. A bone-remodelling algorithm and a tissue-healing algorithm, both mechanically driven, were implemented to predict vertebral bone alterations and fusion patterns after nucleotomy, internal fixation, and anterior plate placement. When considering an intact disc height, neither nucleotomy nor internal fixation were able to provide the necessary stability to promote bony fusion. However, when 75% of the disc height was considered, bone fusion was predicted for both techniques. By contrast, an anterior plate allowed bone fusion at all disc heights. A 50% disc-height reduction led to osteophyte formation in all cases. Changes in the intervertebral disc tissue caused BMD alterations in the endplates. From this observations it can be drawn that fusion may be self-induced by controlling the mechanical stabilisation without the need of additional fixation. The amount of tissue to be removed to achieve this stabilisation remains to be determined. © 2019 Elsevier Ltd","Bone healing; Bone remodelling; Internal fixation; Lumbar spinal fusion surgery; Nucleotomy","Disks (machine components); Implants (surgical); Stabilization; Tissue; Bone healing; Bone remodelling; Internal fixation; Nucleotomy; Spinal fusion; Bone; algorithm; Article; biomechanics; bone density; bone remodeling; bone tissue; controlled study; human; human tissue; intervertebral disk hernia; lumbar spine; nerve ending; nucleotomy; observational study; orthopedic surgery; ossification; osteophyte; osteosynthesis; priority journal; process model; spine stabilization; bone development; computer simulation; finite element analysis; intervertebral disk; lumbar vertebra; percutaneous discectomy; physiology; spine fusion; surgery; Algorithms; Bone Density; Bone Remodeling; Computer Simulation; Diskectomy, Percutaneous; Finite Element Analysis; Humans; Intervertebral Disc; Lumbar Vertebrae; Osteogenesis; Spinal Fusion",,,,,"Deutsche Forschungsgemeinschaft, DFG: SCHM 2572/4-1, SCHM 2572/5-1; Ministerio de Economía y Competitividad, MINECO: DPI2016-79302-R; Ministerul Educaţiei Naţionale: FPU13/01070","This work was supported by the Spanish Ministry of Education, Culture and Sports, Spain (Grant FPU13/01070) and by the Spanish Ministry of Economy and Competitiveness, Spain (DPI2016-79302-R), as well as by the German Research Foundation, Germany (SCHM 2572/4-1, SCHM 2572/5-1).","This work was supported by the Spanish Ministry of Education, Culture and Sports, Spain (Grant FPU13/01070)and by the Spanish Ministry of Economy and Competitiveness, Spain (DPI2016-79302-R), as well as by the German Research Foundation, Germany (SCHM 2572/4-1, SCHM 2572/5-1).","This work was supported by the Spanish Ministry of Education, Culture and Sports , Spain (Grant FPU13/01070 ) and by the Spanish Ministry of Economy and Competitiveness , Spain ( DPI2016-79302-R ), as well as by the German Research Foundation , Germany ( SCHM 2572/4-1 , SCHM 2572/5-1 ).",,,,,,,,"Antonacci, M.D., Hanson, D.S., Leblanc, A., Heggeness, M.H., (1997), pp. 2401-2. , Regional variation in vertebral bone density and trabecular architecture are influenced by osteoarthritic change and osteoporosis.

Based on the virtual work principle and dynamic finite element theory, the spatial element stiffness matrix, mass matrix and earthquake mass matrix of a thin-walled box girder having 9 freedom degrees at each node are deduced. The D’Alembert vibration equation is also established. Newmark-β method is used through MATLAB to solve the seismic response of a long-span continuous curved box girder bridge under El-centro seismic waves. Meanwhile the spatial finite element model of the whole bridge is established by ANSYS. The results indicate that the dynamic responses of pier columns exhibit spatiality. The dynamic response of a bridge structure under 2D coupling horizontal seismic excitation is much bigger than that under 1D horizontal seismic excitation. The critical angle of seismic waves is 50° for radial displacement response. Theoretical calculation results are in agreement with the finite element analysis results. The deduced element matrix not only can be used to calculate the seismic response of long-span curved beam bridge structures but also can provide significant references for the structures in vibration response caused by moving traffic. © 2019 Heng Cai, et al.","Element matrix; Finite element; Long-span curved box girder bridge; Newmark-β method; Seismic response","Box girder bridges; Finite element method; Seismic response; Seismic waves; Steel bridges; Stiffness matrix; Thin walled structures; Bridge structures; Curved box girder bridges; Element matrix; Finite element; Horizontal seismic excitation; Long span; Long-span curved box girde bridge; Mass matrices; Newmark-β method; Seismic excitations; Dynamic response",,,,,,,,,,,,,,,,"Reissner, E., Analysis of shear lag in box beams by the principle of the minimum potential energy (1946) Quarterly of Applied Mathematical, 4 (3), pp. 268-278; Dezi, L., Mentrasti, L., Nonuniform bending-stress distribution (Shear lag) (1985) Journal of Structural Engineering, 111 (12), pp. 2675-2690; Jonsson, J., Distortional theory of thin-walled beams (1999) Thin-Walled Structures, 33 (4), pp. 269-303; Xun, X., Shizhong, Q., Theoretical research on distortion analysis of thin-walled box girder (2013) Engineering Mechanics, 30 (11), pp. 192-201. , (in Chinese); Xie, X., Jianyuan, H., Three dimensional analysis for warping distortion and shear lag effect of thin-walled box girder bridge under restrained torsion (1995) China Civil Engineering Journal, 28 (4), pp. 3-14. , (in Chinese); Chenglong, W., Qinyuan, Z., A new element for thin-walled curved box girder analysis including warping distortion and shear lag effects (2000) China Civil Engineering Journal, 33 (6), pp. 82-87. , (in Chinese); Zhen, Z., Youqin, L., Flexure torsional analysis of curved box girders by stiffness method (1999) China Journal of Highway and Transport, 12 (4). , in Chinese; Deshan, C., Li, Q., An analytical method of vibration analysis for curved-girder bridges (2005) China Civil Engineering Journal, 38 (10). , in Chinese; Hugo, C., Paul, J., Maria, Q., Sungchil, L., Testing and long-term monitoring of a curved concrete box girder bridge (2011) Engineering Structures, 33 (11), pp. 2861-2869; Taysi, N., Ozack, M., Free vibration analysis and shape optimization of box-girder bridges in straight and curved planform (2002) Engineering Structures, 24 (5), pp. 625-637; Zhou, W.B., Jiang, L.Z., Yu, Z.W., Analysis of free vibration characteristics of steel-composite box -girder considering shear lag and slip (2013) Journal of Central South University, 20 (9), pp. 2570-2577; Ji, W., Deng, L., Liu, S.Z., Study of vertical bending vibration behavior of continuous prestressed concrete box girders with corrugated steel webs (2016) Advances in Structural Engineering, 19 (6), pp. 953-965; Chen, X., Guan, Z.G., Li, J.Z., Shake table tests of tall-pier bridges to evaluate seismic performance (2018) Journal of Bridge Engineering, 23 (9). , https://doi.org/10.1061/(ASCE)BE.19435592.0001264; Tubaldi, E., Tassotti, L., Dall'asta, A., Dezi, L., Seismic response analysis of slender bridge pier (2014) Earthquake Engineering and Structural Dynamics, 43 (10), pp. 1503-1519; Elkady, A.Z., Seleemah, M.A., Ansari, F., Structural response of a cable-stayed bridge subjected to lateral seismic excitation (2018) Journal of Civil Structural Health Monitoring, 8 (3), pp. 417-430; Maili, C., Li, Q., Lei, Y., Experimental study on seismic of irregular high piers curved bridges under multi-point excitation (2016) Journal of Vibration Engineering, 29 (5), pp. 874-880; Maili, C., Li, Q.N., Junhong, Y., Shaking table test of irregular curved bridges with high piers (2016) Journal of Vibration and Shock, 35 (2), pp. 24-30. , (in Chinese); Soyluk, K., Comparison of random vibration methods for multi-support seismic excitation an analysis of long-span bridges (2004) Engineering Structures, 26 (11), pp. 1573-1583; Nuti, C., Vanzi, I., Influence of earthquake spatial variability on differential soil displacements and SDF system response (2005) Earthquake Engineering and Structural Dynamics, 34 (11), pp. 1353-1374; Lupoi, A., Franchin, P., Pintop, E., Seismic design of bridges accounting for spatial variability of ground motion (2005) Earthquake Engineering and Structural Dynamics, 34 (4-5), pp. 327-348; He, F., The finite element method for thin-walled elastic curved beams (1981) Chinese Journal of Solid Mechanics, 2 (2), pp. 141-157. , (in Chinese); Bofang, Z., (2009) The Finite Element Method Theory and Applications, , Third Edition, China Water Power Press, Beijing, (in Chinese); (2015) General Specifications for Design of Highway Bridges and Culverts, , China Communication Press, Beijing, (in Chinese); Clough, R.W., Penzien, J., (2003) Dynamics of Structures, , Third Edition, Computers and Structures, Inc., Berkeley","Cai, H.; School of Civil Engineering, China; email: hengheng_hahei77@126.com",,,"EXTRICA",,,,,13928716,,,,"English","J.

Good bonding at their interface is essential for ensuring that steel and concrete can work well together. However, if interfacial slippage does occur it not only hinders the plasticity of a beam’s performance in full section but also weakens its strength and stiffness. To study the mechanism of slip occurrence and its impact, eight prestressed CFST rectangular beams were tested under monotonic loading. Slippage was measured during the entire loading procedure. Based on the elasto-plastic theory, a nonlinear finite element model, considering slippage is developed in this paper. The results show that slippage occurred when the concrete began to crack. This plays an important role in the overall performance of a beam after the steel has yielded. The maximum slip occurred near the section of quarter-span. To some extent, the slip curves generated by this model agreed with the test results, and it could be used to predict the bending capacity of prestressed CFST beams. © 2018, Iran University of Science and Technology.","Bond–slip relationship; Finite element model; Prestressed concrete-filled steel tubes","Bridges; Finite element method; Stiffness; Tall buildings; Tubular steel structures; Bending capacity; Concrete-filled steel tubes; Elasto-plastic theory; Monotonic loading; Non-linear finite element model; Pre-stressed; Rectangular beams; Strength and stiffness; Prestressed concrete",,,,,"2017GZ0369; Sichuan Province Science and Technology Support Program: 2018GZ0052; Ministry of Science and Technology of the People's Republic of China, MOST; National Basic Research Program of China (973 Program): 2016YFB1200401","Acknowledgements We gratefully acknowledge the support of the Sichuan Science and Technology Program (Grant 2018GZ0052), the National Key Research and Development Program of China (Grant 2016YFB1200401), and the Science and Technology Project of Sichuan Province (Grant 2017GZ0369) for the research reported in this paper.","Funding The Sichuan Science and Technology Program (Grant 2018GZ0052), Sichuan provincial science and Technology Department, China.

In this hybrid isolator, the friction–yielding part has an energy absorption feature, where the rubber pad has re-centering and vertical bearing capacity. For this purpose, an X-shaped metal damper with different number and thickness, and sliding surfaces with different friction coefficients is applied and the effect of vertical load variations on the results is assessed. Using the hysteresis force-displacement diagrams of different FYEB and lead rubber bearing (LRB) with the same dimensions at shear strains of 50, 100, and 150%, effective horizontal stiffness, energy dissipation, equivalent viscous damping, and lateral force at each loading cycle are assessed and compared. It can be concluded that the proposed isolator has a more suitable and stable performance at all shear strains than LRB. In addition, by changing FYEB parameters, a wide range of performance can be achieved. © The Author(s) 2019.","finite element analysis; Hybrid isolator; hysteresis behavior; lead rubber bearing; sliding isolator; X-shaped metal damper","Bridge bearings; Damping; Energy dissipation; Finite element method; Hysteresis; Nonmetallic bearings; Rubber; Shear strain; Hybrid isolator; Hysteresis behavior; Lead rubber bearing; sliding isolator; X-shaped metal damper; Friction",,,,,,,,,,,,,,,,"(2012) Abaqus/CAE User’s Manual, , http://xn-90ajn.xn-p1ai/library/abaqus_doc/Documentation/docs/v6.12/pdf_books/CAE.pdf; Abe, M., Yoshida, J., Fujino, Y., Multiaxial behaviors of laminated rubber bearings and their modeling.

Since inadequate liquid transfer can produce defects that are detrimental to printed products, electric fields are sometimes applied to enhance transfer, a method known as electrostatic assist (ESA). Because the physical mechanisms underlying ESA are not well-understood, we examine here the influence of electric fields on liquid transfer in two model geometries, both of which involve liquid bridges with moving contact lines. The bridges are axisymmetric and confined between two electrodes, one of which is flat and moves vertically upward, and the other which either is flat or has a cavity and is stationary. An electric field is applied in the axial direction, both perfect and leaky dielectric liquids are considered, and the governing equations are solved with the Galerkin finite-element method. For liquid transfer between two flat plates, application of an electric field stabilizes the liquid bridge. This allows more time for the contact line to retract on the less wettable surface and leads to an increase in liquid transfer to the more wettable surface. Tangential stresses due to surface charge can significantly enhance liquid transfer, even to the less wettable surface if the tangential stresses point toward that surface. For liquid transfer between a flat plate and a cavity, the electric field increases the pressure gradient near the contact line on the cavity wall, causing the contact line to slip and more liquid to be transferred from the cavity. Notably, the effect is more pronounced for a deep cavity, resulting in a larger percentage of liquid transferred compared to a shallow cavity. In contrast to the case of liquid transfer between two flat plates, surface charge does not have as significant an influence on liquid transfer due to the way the cavity and electric field modify the interface shape near the contact line. The results of this work illustrate the physical mechanisms through which electric fields can improve liquid transfer, and they provide guidance for optimizing ESA in industrial printing processes. © 2019 American Physical Society..",,"Dielectric liquids; Electric fields; Printing presses; Surface charge; Galerkin finite element methods; Governing equations; Industrial printing; Moving contact lines; Physical mechanism; Printed products; Provide guidances; Tangential stress; Electric lines",,,,,"University of Minnesota, UM","This work was supported through the Industrial Partnership for Research in Interfacial and Materials Engineering of the University of Minnesota.

To design for such loads, widely used bridge design standards use an approach in which impact loads are computed from the kinetic energy of either a single impacting barge or a multibarge flotilla. Within a flotilla, individual barges are arranged into columns and rows and are connected together with lashing elements, such as wire-rope cables. During impact these lashings elongate and may rupture, influencing the degree of overall flotilla mass that contributes to impact force generation. In this study, finite-element impact simulations are used to investigate lashing deformation and relative sliding between barge columns during flotilla impacts with bridge piers. After analytically quantifying the fraction of overall vessel mass, which contributes to impact load generation, an ""effective flotilla mass"" is formulated for use in bridge design. Importantly, the majority of impact simulation results indicate that the effective flotilla mass is nearly equal to total flotilla mass rather than the impacting-column mass presently assumed by bridge design standards. © 2019 American Society of Civil Engineers.","Barges; Bridge loads; Finite-element analysis; Impact energy; Nonlinear dynamics","Dynamics; Finite element method; Jack-up rigs; Kinetic energy; Kinetics; Loads (forces); Bridge design; Bridge loads; Impact energy; Impact force; Impact loads; Impact simulation; Relative motion; Barges",,,,,,,,,,,,,,,,"(2009) Guide Specification and Commentary for Vessel Collision Design of Highway Bridges., , AASHTO. 2nd ed.

This paper presents the results of advanced numerical studies of selected structural systems using a novel joint finite element and information gathered from an extensive experimental campaign of various types of joints commonly found in Cuplok falsework structures. Different hazardous scenarios identified as being critical to the structural performance of bridge falsework systems are analysed, such as ground settlements, bracing configurations and falsework systems using steel beam girders. For each considered hazardous scenario, structural behaviour and resistance are analysed and discussed. From the results, relevant practical information was obtained that can be used to reduce the risks associated with bridge falsework systems. For example, it was found that even a small value of isolated differential ground settlements could reduce the resistance of the system by more than 10%. In addition, for falsework systems using steel beam girders, it was found that inappropriate bracing of falsework towers could lead to a 50% reduction in system resistance. © 2018 ICE Publishing: All rights reserved.","safety and hazards; steel structures; temporary works","Cast in place concrete; Construction industry; Hazards; Settlement of structures; Steel beams and girders; Steel structures; Bracing configuration; Experimental campaign; Safety and hazards; Structural behaviour; Structural performance; Structural systems; Temporary structures; temporary works; Bridges; bridge; concrete; construction industry; finite element method; numerical model; safety; steel; structural component",,,,,"SFRH/BD/70993/2010","The authors acknowledge financial support from Fundação para a Tecnologia e a Ciência through a PhD scholarship (SFRH/BD/70993/2010) given to the first author.

To avoid using a trial-and-error method to determine the maximum moment section and unify the methods to determine the arm length of the maximum moment in the conventional Gergely-Sozen (G-S) model, a modified G-S model is proposed to calculate the spalling force in a pretensioned anchorage zone. A compression dispersion model (CDM) is developed and formulated for the pretensioned anchorage zone, and the extreme edge of isostatic lines is visualized mathematically with its geometric and physical boundary conditions, which can be used to accurately predict the arm length and spalling force of the horizontal moment at any horizontal section. Based on experimental and field observations and previous finite-element method (FEM) analysis results, the junction section between the bottom flange and the web, instead of the maximum moment section, is recommended as a critical control section to calculate the spalling force in the web. Compared with the numerical and experimental results, a good agreement was obtained confirming that the modified G-S model method not only can predict the arm length of the horizontal moment, but can also evaluate the magnitude of the spalling force. A case study illustrates how to apply the proposed method to calculate the spalling force at the junction section, and the results explain why horizontal cracks often occur at the junction section. © 2018 American Society of Civil Engineers.","Compression dispersion model (CDM); Modified Gergely-Sozen model; Spalling force","Anchorage zones; Anchorages (foundations); Box girder bridges; Dispersions; Highway bridges; Numerical methods; Plate girder bridges; Prestressed concrete; Prestressing; Dispersion modeling; Field observations; Finite element method analysis; Horizontal section; Model derivations; Prestressed bridge girders; Prestressing forces; Trial-and-error method; Spalling",,,,,,,,,,,,,,,,"(2013) Interim Revisions to the AASHto LRFD Bridge Design Specifications, , AASHTO. 6th ed.

In this study the critical load for distortional buckling is established based on the energy method and a beam on elastic foundation (BEF) approach. In the theoretical model the capacity is created by elastic bending of the chord faces in their own planes and elastic bending of the cross-section as a frame structure. The theoretical capacity of an X-joint is compared with numerical results obtained from finite element analyses (FEAs). Some discrepancy was found between theoretical model and numerical analysis, with the theoretical model slightly underestimating the load-carrying capacity. Experimental tests show that an X-joint can be prone to distortional buckling failure mode. However, detailed scrutiny of distortional buckling failure in X-joints is only legitimate for joints made of high-strength steel (HSS), because other failure mechanisms are more critical when conventional steels are used. Nevertheless, designers of X-joints with rectangular hollow section (RHS) members should be aware of this potential failure mode. © 2019 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co.

Conceptual aircraft design typically relies on empirical models and hand methods for initial sizing of aircraft structure. These methods have limited applicability to new aircraft configurations that diverge significantly from the historical configurations on which they are based. The ATLASS tool is intended to bridge the gap between conceptual and detailed design by implementing higher fidelity automated analysis tools earlier in the design process. The ATLASS tool includes fully automated modules for Outer Mold Line (OML) generation, internal structural layout, weights and C.G. generation, and Finite Element Model (FEM) generation for loads and structural analysis. The configuration and analysis model generation is performed in CATIA. Loads and structural sizing are performed in NASTRAN and HyperSizer respectively. Isight is then used to integrate the analysis modules and manage the higher level optimization and design space exploration. The framework of ATLASS is fully automated and parametric which enables structural trade studies to be conducted on any aircraft variable such as sweep, aspect ratio, etc. © 2019 by the American Institute of Aeronautics and Astronautics, Inc.

Except for assembling the equation of motion of vehicle only via the principle of virtual work, the fully computerized approach is further expanded to assemble the governing equation of fluctuating current via the equilibrium relation. A state-space equation couples the equation of motion of the vehicle and the governing equation of fluctuating current. The equation of motion of a real three-span space continuous girder bridge is established by using finite element methods. A separated iteration method based on the precise integration method and the Newmark method is introduced to solve the state-space equation for the maglev vehicle and the equation of motion for the bridge. Moreover, a new scheme to application of the pseudoexcitation method (PEM) in random vibration analysis is proposed to maximize the computational efficiency of the random vibration analysis of the maglev vehicle-bridge system. Finally, the numerical simulation demonstrates that the proposed framework can efficiently obtain the mean value, root mean square (RMS), standard deviation (SD), and power spectral density (PSD) of dynamic response for the coupled 3D maglev vehicle-bridge system. © 2019 Wei Liu and Wenhua Guo.",,,,,,,"National Natural Science Foundation of China, NSFC: 51078356","This research was supported by the National Natural Science Foundation of China (Project no. 51078356)",,,,,,,,,,"Plotkin, D., Kim, S., Maglev guideway cost and construction schedule assessment (1997) Journal of Transportation Engineering, 123 (3), pp. 195-198. , 2-s2.0-85001686686;

The fjord is c. 5 km wide with a maximum depth of 550 m at the proposed bridge crossing. The main geohazards of concern are submarine slope instabilities. To identify locations of instability, their susceptibility to failure, and their potential runout distances, we performed the following analyses: (1) static and pseudo-static limit equilibrium analyses for the entire fjord crossing area; (2) 1D seismic slope stability sensitivity analyses for different slope angles and soil depths; (3) 2D static and pseudo-static finite element analyses for selected profiles; (4) back-analysis of a palaeolandslide; and (5) quasi-2D and quasi-3D landslide dynamic simulations calibrated using results from the back-analysis. The workflow progresses from simplified to more advanced analyses focusing on the most critical locations. The results show that the soils in many locations of the fjord are potentially unstable and could be the loci of landslides and debris flows. The evidence of numerous palaeosubmarine landslides identified on geophysical records reinforces this conclusion. However, the landslide triggers and timing are currently unknown. This paper demonstrates the need for comprehensive and multidisciplinary geohazard analyses for any infrastructure projects conducted in fjords. © 2018 The Author(s).

In principle, nonlinear finite element modeling (FEM) can be rigorously applied for large monumental structures. However, these approaches still require high computational resources and specific expertise that limit their application to few academic studies or significant cases. For these reasons, several researches are currently involved in the formulation and validation of alternative numerical strategies to be efficiently applied for the structural assessment of masonry monumental structures. Among the simplified approaches, a widely used strategy is the so-called equivalent frame model (EFM), which has received several numerical and experimental validations. In this study, after a description of the recent evolutions of the EFM, an original discrete macroelement method, developed by the authors in the last decade, is presented. The method is based on a discrete macroelement discretization in which the interaction between the shear deformable elements is governed by zero-thickness interfaces that also rule the mechanical behavior of the corresponding adjacent elements according to a straightforward fiber discretization strategy. The approach requires a very low computational burden, compared to classical nonlinear FEM simulations, and allows efficient modeling of large masonry structures such as churches, monumental buildings, or masonry arch bridges. Several comparisons with numerical and experimental results show the ability of the proposed discrete macroelement method to efficiently simulate the nonlinear behavior of historical masonry structures. © 2019 Elsevier Ltd.

The longitudinal thermal movement of the superstructure is usually considered as the key parameter for designing jointless bridges. The average temperature of cross‐sections can be considered as the effective temperature of the superstructure. In order to accurately estimate the longitudinal thermal movement of the superstructure, the average temperature of cross‐sections should be obtained. The temperature distribution on cross‐sections of T‐shaped girders in one jointless bridge was monitored. A finite element model was implemented using the MIDAS‐FEA software, which is verified based on the monitoring results. Considering the historical extreme temperature conditions and the results of the parametric study, the peak values of the average temperature of T‐shaped girder cross‐sections for jointless bridges in different climate regions in China are recommended. Finally, the simplified formulae to predict the effective temperatures of T‐shaped girder cross‐sections for jointless bridges are proposed based on the correlation analysis. © 20th Congress of IABSE, New York City 2019: The Evolving Metropolis - Report.

A girder bridge constructed using high-performance, high-strength concrete has been instrumented and tested under controlled-load condition. AASHTO LRFD distribution factors were compared to the factors computed from girders measured strains. AASHTO LRFD distribution factors were on average 21% higher than computed factors. A detailed finite element model (FEM) was developed and calibrated to match the controlled load test results. Several variations of the FEM were created to account for the presence of end intermediate diaphragms, girders continuity, and bridge skewness. The addition of end diaphragms decreases distribution factors on average by 6% while addition of intermediate diaphragms redistributes the moments between interior and exterior girders. Effect of diaphragms was more evident for bridge with large skew angles and less significant for skew angles less than 20°. Bridges with skewness have decreased distribution factors which was evident for skew angle in excess of 20°; AASHTO LRFD has good estimates of skewness effect on distribution factors. Considering the continuity effect in the calibrated FEM revealed that AASHTO LRFD distribution factors are overestimated on average by 17%. © 2019 - IOS Press and the authors.

Therefore, it is very important to predict the bursting force to determine appropriate reinforcement details. In the present work, the existing equations of the bursting force for the anchorage zone were evaluated and an equation for the bursting force based on finite element analysis was proposed to improve the model's accuracy. Parametric analysis was performed considering the anchorage shape, tendon angle, and eccentric distance. The analytical results indicate that the existing equations underestimate or overestimate the bursting force.

Additionally, the stiffness of diaphragmatic plates has been introduced in the formulation in order to compare with the case where rigid diaphragms are assumed. Isogeometric tools (NURBS) are employed in order to obtain the results for the 1D formulation and 3D shell models are developed in FEM commercial software for composite cross sections with diaphragms. The number of intermediate diaphragms according to bridges design specifications is compared to the analyzed diaphragmatic arrangements in order to assess the overall structural behavior of bridges decks.

Current procedures used for classifying structural cracking of reinforced and prestressed concrete structures generally consist of various rating criteria comprised of pre-established concrete crack width and/or length limits. While concrete cracking data obtained from routine inspections of this type can aid in identifying elements that are degrading or are exhibiting signs of distress, these inspections typically provide very limited insight into the implications of the damage. Furthermore, inspection evaluation criteria are almost always independent of member-specific details; for example, properties such as reinforcement layout and volumes, material strengths, and member geometry are usually not considered when assessing the severity of measured concrete cracking. This paper presents an overview of a smeared fixed-crack reinforced concrete membrane element analysis procedure that employs visually-measured diagonal concrete cracking data (e.g., concrete crack widths, inclinations, etc.) as input to provide estimates of concrete member material stresses, in-service load levels, and residual shear strengths. Furthermore, transverse normal stresses that arise in disturbed regions of beams are investigated in a finite element analysis parametric study. Refinements to existing models for transverse stress proportions are proposed and implemented within the crack-based assessment procedure. The procedure is shown to provide meaningful estimates pertaining to the residual capacities of full-scale reinforced concrete bent cap test specimens and in forecasting “critical” diagonal crack widths for bridge monitoring purposes. It is envisioned that idealized cracked-continuum modelling approaches, such as the type presented in this paper, can supplement traditional inspection procedures and can be used to better assess structure safety and prioritize maintenance efforts associated with growing inventories of aging and degrading reinforced concrete infrastructure. © Federation Internationale du Beton (fib) - International Federation for Structural Concrete, 2019.","Bent cap; Bridges; Damage assessment; Deep beam; Shear modelling","Bridges; Composite bridges; Continuum mechanics; Damage detection; Data visualization; Prestressed concrete; Reinforced concrete; Assessment procedure; Bent caps; Damage assessments; Deep beam; Inspection procedures; Reinforcement layout; Residual shear strength; Transverse normal stress; Structural design",,,,,"Texas Department of Transportation, TxDOT; Federal Highway Administration, FHWA","The authors wish to acknowledge the support of the Dwight David Eisenhower Transportation Fellowship Program from the Federal Highway Administration and the Texas Department of Transportation, which made this research possible.",,,,,,,,,,"(2010) AASHTO Bridge Element Inspection Guide Manual, , AASHTO 1st ed; (2017) AASHTO LRFD Bridge Design Specifications, , AASHTO 8th ed.).

The use of Fiber Reinforced Polymer (FRP) strips plates and fabric for strengthening of reinforced concrete structures has well established design guidelines and standards. Research on the application of FRP composites to steel structures compared to concrete structures is limited, especially for shear strengthening applications. Whereas, there is a need for cost-effective system that could be used to strengthen steel high-way bridge girders to cope with losses due to corrosion in addition to continuous demands for increasing traffic loads. In this study, a parametric finite element study is performed to investigate the effect of applying thick CFRP strips diagonally on webs of plate girders on the shear strength of end-web panels. The study focuses on illustrating the effect of several geometric parameters on nominal shear strength. Hence, a formula is developed to determine the enhancement of shear strength gained upon the application of CFRP strips.

In addition, the influence of the small air-gap in the bridge lamination on a field-weakening range (FWR) of the machine is evaluated by three-dimensional finite-element analysis (3-D FEA).

The sag effects and wind-induced responses can be reduced with the proposed system because tie-down cables are short and aesthetic compared with traditional stiffening cables. The results show that the stiffening effect of tie-down cables is better than that of traditional stiffening cables in controlling the displacement and internal force of the bridge based on a static experiment and finite element analysis. Therefore, the proposed system can greatly improve the overall stiffness of a bridge, and its stiffening effect is better than that of traditional stiffening cables in controlling the displacement and internal force.

In view of the periodicity of the viaduct, the mass-viaduct interaction force is expanded into a Fourier series first, each term of which represents one component of the interaction force. By using the Fourier transform method and finite element method (FEM), the frequency domain response of the periodic viaduct to each interaction force component is obtained. The time domain response of the periodic viaduct to the force component can be recovered by applying the inverse Fourier transform to the corresponding frequency domain response. With the mass-viaduct coupling condition and the time domain response of the viaduct to the force component, the Fourier coefficients of the mass-viaduct interaction force are obtained. Superposing the responses of the periodic viaduct due to all the interaction force components yields the response of the periodic viaduct to the moving mass. Numerical results show that the force-weight ratio increases with increasing mass and speed of the mass, suggesting that the inertial effect of the moving mass should be taken into account for the large mass with high speeds. Also, it is found that for the case of the large moving mass with high speeds, the mass-viaduct interaction force may become negative, indicating that the mass has a tendency to separate from the viaduct in this case. © 2018","Inertial effect; Moving mass; Periodic viaduct; The finite element method (FEM); The Fourier transform","Finite element method; Fourier analysis; Fourier series; Frequency domain analysis; Inverse problems; Time domain analysis; Fourier coefficients; Fourier transform method; Frequency domain response; Inertial effect; Inverse Fourier transforms; Moving mass; Periodic viaduct; Time domain response; Bridges",,,,,"National Natural Science Foundation of China, NSFC: 11272137, 51878277; Government of Jiangsu Province: BK20150512","Financial support received from the National Natural Science Foundation of China (No. 11272137 , 51878277 ) and Jiangsu Province ( BK20150512 Youth Funding) is highly acknowledged by the authors.",,,,,,,,,,"Akin, J.E., Mofid, M., Numerical solution for response of beams with moving mass (1989) J.

Unlike land bearings that are to absorb high-frequency vibration during earthquakes, offshore elastomeric bearings are to support topside-module weight while efficiently absorbing wave-induced hull motions. The bearing is to receive three loads: Compression, shear, and bending, and providing sufficient stiffness to resist the loads by inserting an adequate number of reinforcing plates is a major design issue for marine bearings. The stiffness of elastomeric bearings is largely influenced by the ratio of height to the area of the bearing and the number of laminated reinforcing plates. In this study, for the given size of the elastomeric bearing, the effect of the number of reinforcing plates on its compression, shear, and bending stiffness is investigated by using ANSYS Mechanical APDL, a commercial structural FE (finite element) analysis program. First, full analysis is done for the compression, shear, and bending stiffness with increasing respective displacements and the number of reinforcing plates from 0 to 8. The numerical results are partly validated by authors’ experimental results. Based on the numerical results, several empirical formulas are suggested for the variation of the three stiffnesses as a function of the number of reinforcing plates. Next, the design of the elastomer bearing for a representative FPSO (Floating Production Storage and Offloading) operated in the North Sea is conducted according to the required load and displacement conditions. Then, the adequate number of reinforcing plates for the case is determined and the results are shown to satisfy all the required safety factors for various required loading conditions. © 2020 by the authors.

The influence of the key design parameters including; number of turns per phase, stack length, distance and angle between V-shaped magnets, rotor yoke thickness, magnetic bridge width and thickness and number of magnet segments on the flux-weakening (FW) performance characteristics are evaluated in detail. The influence of material of segmentation (material of bridge namely, air or iron) is also considered. A combination of analytical calculation-based program and a time-stepping 2D finite-element analysis based program are employed to evaluate the FW characteristics. The accuracy of the FW calculations, particularly the performance at high-speed regions, is verified over changes in torque components; namely reluctance and permanent magnet (PM), inductance components, PM flux coefficient and inverse saliency ratio due to the change in considered design parameter. The electromagnetic torque, torque ripple, output power and FW capability are investigated by parametric analyses. Moreover, the power losses and efficiency maps together FW curves are calculated for the optimal NSW IPM machine. The experimental measurements, taken from manufactured prototype, verify that the performed analyses and methods described in this study are accurate and reliable. © The Institution of Engineering and Technology 2020.",,"Bridges; Deflection yokes; Inverse problems; Permanent magnets; Analytical calculation; Design parameters; Design studies; Flux weakening; Interior permanent magnet machine; Key design parameters; Magnetic bridge; Parametric study; Performance; Performance characteristics; Winding",,,,,,,,,,,,,,,,"(2014) Synthesis Report, , hdl:10013/epic.45156; Soong, W.L., Ertugrul, N., Field-weakening performance of interior permanent-magnet motors (2002) IEEE Trans.

Despite the wide use of caissons in bridge engineering, until a few years ago this foundation typology has been less investigated than piles and shallow foundations in both static and dynamic field. In most of the published studies, the seismic design of bridge piers was carried out without accounting for soil-structure interaction or by means of an uncoupled approach in which the superstructure was solved independently from the soil-caisson subsystem. In this study, coupled systems made of soil, caisson, pier and deck were analyzed in the time domain by a 3D finite element approach, considering rigid and massive caissons embedded in linear viscoelastic soils. In addition to unravelling the contribution of kinematic and inertial interaction to the total response of the caisson-bridge-pier systems, the study focuses on a particular aspect of kinematic interaction, overlooked in practical design and in most of previous studies, represented by the kinematic bending arising in the bridge pier due to the pier-to-deck joint rigidity. For some critical combinations of soil compliance, caisson geometry, pier height and input motion characteristics, the pier-deck constraint could induce kinematic bending moments in the pier as important as the inertial ones. A closed-form equation was finally proposed to predict the maximum kinematic moment in the bridge pier as a function of the key model parameters identified through the parametric study. © 2020 Elsevier Ltd","Caissons; Dynamic soil-structure interaction; Finite element analysis; Kinematic interaction; Pier-to-deck joint stiffness","Bridge piers; Caissons; Embedded systems; Kinematics; Seismic design; Seismic response; Soil structure interactions; Soils; Viscoelasticity; 3-D finite elements; Bridge engineering; Closed-form equations; Kinematic interaction; Linear viscoelastic; Shallow foundations; Supported bridges; Viscoelastic soil; Pressure vessels; caisson; dynamic response; finite element method; kinematics; seismic response; soil-structure interaction; stiffness; structural component; viscoelasticity",,,,,"Dipartimento della Protezione Civile, Presidenza del Consiglio dei Ministri, DPC","This study was carried out within the framework of the 2019–2021 ReLUIS research programmes funded by the Italian Civil Protection Department (DPC) , as contribution to the geotechnical Work Package 16 coordinated by F.

While research is ongoing in this field, limited work has been done involving structures that are truly representative of real-world, aged civil infrastructure requiring assessment. Thus, this paper presents the results of an experimental program and subsequent numerical investigation into the performance of a diagonally cracked, RC bent cap that was removed from a 60-year-old bridge in Texas. Extensive work was done to document the cracking behavior and characterize the mechanical properties of the bent cap prior to ultimate load testing. The numerical investigation included both “conventional” methods and nonlinear finite element analysis (with and without consideration of existing damage). Ultimately, the results of the experimental and numerical investigations suggest that, while the bent cap was exhibiting large-width shear cracks in service, the damage was not indicative of an impending shear failure. © 2020 fib.

The Gaussian process response surface method in Bayesian principle is adopted to optimize and correct the model. Because Gaussian process is a non-parameter model with high sensitivity, reliable accuracy, and small calculation, it avoids repeatedly using finite element model. This makes the efficiency of finite element correction improve significantly. A continuous beam bridge is adopted as a study case. In sample selection, an improved uniform design method based on weighting is designed to improve the learning efficiency and prediction accuracy of the model while using ANSYS to analyze and predict the typical bridge. The analysis of the date of the bridge dynamic test is used to correct the finite element model, obtain the actual parameters of the bridge structure, and predict the measured data of the bridge static load test based on the modified finite element model. © 2020 fib.

Research and practical experience both showed that the smooth epoxy coating significantly reduces the bond between concrete and reinforcing steel, which often results in the early development of transverse cracks in bridge decks. To solve this problem, the Illinois Department of Transportation (IDOT) proposed a new type of textured epoxy-coated (TEC) reinforcing bars with applied roughness to improve the bond between concrete and steel while providing corrosion protection. This study investigates the surface roughness of six different types of TEC bars and how it impacts the bar's bond-slip behavior with concrete. First, the surface roughness of the TEC bars is compared with that of uncoated black bars (BLK) using 2-D parameters Ra, Rz, and 3-D parameters Sa and Sz. Second, direct pull-out tests are conducted on concrete specimens with embedded 1) BLK, 2) smooth epoxy-coated (SEC), and 3) all six TEC bars to compare their bond characteristics. Finally, a 3-D finite element model is developed and calibrated to simulate the bond-slip behavior of TEC bars embedded in concrete. The results show that the average surface roughness of TEC bars is 3–4 times that of the uncoated bars. Further, TEC bars generally exhibit higher slip resistance than the uncoated and smooth epoxy-coated bars. © 2020","Bond-slip; Finite element analysis; Pull-out test; Reinforcement; Roughness; Textured epoxy-coated","Bridge decks; Corrosion resistant coatings; Epoxy resins; Rebar; Steel corrosion; Surface roughness; Textures; 3D finite element model; Average surface roughness; Bond characteristics; Concrete specimens; Department of Transportation; Epoxy-coated reinforcing; Evaluation of surface roughness; Practical experience; Concretes",,,,,"Illinois Department of Transportation, IDOT: R27-197","This work was supported by the Illinois Center for Transportation and the Illinois Department of Transportation under Project No. R27-197 .",,,,,,,,,,"(2017), https://www.infrastructurereportcard.org/cat-item/bridges/, American Society of Civil Engineers.

However, two common uncertainty factors, namely manufacturing tolerance on the flux-bridge width and the BH-curve, may considerably affect rotor saliency. In this paper, a comprehensive sensitivity analysis based on 2D FEA, regarding these two uncertainty factors is carried out, considering in particular a SynRM prototype machine of 6kW with 3000rpm rated speed. The analysis results show that the influence of the manufacturing tolerance on flux-bridge width is negligible, but the impact of stator core magnetic permeability is obvious and considerable for the design of higher performance SynRMs. © 2020 The Institute of Electrical Engineers of Japan.","BH-curve; comprehensive sensitivity analysis; manufacturing tolerance; SynRM","Bridges; Fits and tolerances; Magnetic permeability; Manufacture; Sensitivity analysis; Uncertainty analysis; B-h curves; Manufacturing tolerances; Power factors; Prototype machine; Stator core; Synchronous reluctance machine; Torque density; Uncertainty factors; Synchronous machinery",,,,,"2019C01044, 51690182; National Natural Science Foundation of China, NSFC: 51837010; Natural Science Foundation of Zhejiang Province, ZJNSF: LQ20E070005","This work was supported in part by the Natural Science Foundation of China 51837010, in part by Zhejiang Provincial Natural Science Foundation of China LQ20E070005, in part by the Key R&D Program of Zhejiang 2019C01044, and in part by the Natural Science Foundation of China 51690182.",,,,,,,,,,"Lee, J.H., Design solutions to minimize iron core loss in synchronous reluctance motor using preisach model and FEM (2002) IEEE Trans.

This paper presents considerations for the viability of magnetoelectric composites for wireless power transfer in neural implantation. This is accomplished herein by studying different types of biocompatible encapsulants for magnetoelectric devices, their impact on the output voltage of the composites, and the rigidity of the materials in the context of tissue damage. Simulation results indicate that a polymer encapsulant, rather than creating a substrate clamping effect, increases the voltage output of the magnetoelectric, which can be further improved by careful polymer selection. These attributes are modelled using the finite element method (FEM) with COMSOL Multiphysics. The addition of a 0.2 mm poly(ethyl acrylate) encapsulating layer increases the piezoelectric voltage to 3.77 V AC output at a magnetic field strength of 200 Oe, as the magnetostrictive layer deforms inside the flexible outer polymer. Comparing voltage conditioning circuits, the output is sufficient for low-voltage neuronal stimulation when employing a simple bridge rectifier which boasts minimal charging time and ripple voltage around 1 mV. © 2020 IEEE.","Implantable electronics; Magnetoelectric; Polymer composites; Wireless power","Biocompatibility; Charging time; Energy transfer; Implants (surgical); Polymers; Wireless power transfer; Brain implantable devices; Magnetic field strengths; Magnetoelectric composites; Magnetoelectric devices; Magnetostrictive layers; Piezoelectric voltage; Poly (ethyl acrylate); Voltage conditioning; Electric rectifiers",,,,,"Engineering and Physical Sciences Research Council, EPSRC: 2279645","Eve McGlynn is supported by the Engineering and Physical Sciences Research Council (EPSRC), under grant No. 2279645.",,,,,,,,,,"Das, R., Moradi, F., Heidari, H., Biointegrated and wirelessly powered implantable brain devices: A review (2020) Ieee Trans Biomed Circ Sys, pp. 1-13; Das, R., Heidari, H., A self-tracked high-dielectric wireless power transfer system for neural implants (2019) 2019 26th Ieee International Conference on Electronics, Circuits and Systems (ICECS), pp. 111-112; Bichurin, M., Petrov, V., Srinivasan, G., Theory of lowfrequency magnetoelectric coupling in magnetostrictivepiezoelectric bilayers (2003) Physical Review B, 68 (5), p. 054402; Lanceros-Méndez, S., Martins, P., (2017) Magnetoelectric Polymerbased Composites: Fundamentals and Applications, , John Wiley & Sons; Lam, K., Lo, C., Chan, H.L., Frequency response of magnetoelectric 1-3-type composites (2010) Journal of Applied Physics, 107 (9), p. 093901; Zuo, S., Ultrasensitive magnetoelectric sensing system for pico-tesla magnetomyography (2020) Ieee Transactions on Biomedical Circuits and Systems; Nan, T., Acoustically actuated ultra-compact NEMS magnetoelectric antennas (2017) Nat Commun, 8 (296), pp. 1-8; Rupp, T., Truong, B.D., Williams, S., Roundy, S., Magnetoelectric transducer designs for use as wireless power receivers in wearable and implantable applications (2019) Materials, 12 (3), p. 512; Sun, T., Sun, L., Yong, Z., Chan, H.L., Wang, Y., Estimation of the magnetoelectric coefficient of a piezoelectricmagnetostrictive composite via finite element analysis (2013) Journal of Applied Physics, 114 (2), p. 027012; Jeong, C.K., Comprehensive biocompatibility of nontoxic and high-output flexible energy harvester using lead-free piezoceramic thin film (2017) Apl Materials, 5 (7), p. 074102; (2019) GitHub, , https://github.com/mattdesl/pack-spheres; Vopson, M., Fetisov, Y., Caruntu, G., Srinivasan, G., Measurement techniques of the magneto-electric coupling in multiferroics (2017) Materials, 10 (8), p. 963; Ramasubbu, R., Lang, S., Kiss, Z.H., Dosing of electrical parameters in Deep Brain Stimulation (DBS) for intractable depression: A review of clinical studies (2018) Frontiers in Psychiatry, 9, p. 302; Safety, I.I.C.O.E., Ieee standard for safety levels with respect to human exposure to electric, magnetic, and electromagnetic fields, 0 hz to 300 ghz (2019) Ieee Std C95.1-2019, pp. 1-312; Singer, A., Magnetoelectric materials for miniature, wireless neural stimulation at therapeutic frequencies (2020) Neuron; Lasheras, A., (2015) Energy Harvesting Device Based on a Metallic Glass/PVDF Magnetoelectric Laminated Composite "" Smart Materials and Structures",,,"Glasgow Convention Bureau;IEEE;IEEE Circuits and Systems Society (CAS)","Institute of Electrical and Electronics Engineers Inc.","27th IEEE International Conference on Electronics, Circuits and Systems, ICECS 2020","23 November 2020 through 25 November 2020",,166215,,9781728160443,,,"English","ICECS - IEEE Int.

In some cases, the shear stiffness of partial OHS connectors could be beyond the actual demand, resulting in the uneven distribution of connector shear force. Therefore, the authors proposed the Rubber-Sleeved Stud (RSS) connector to reduce the shear stiffness of OHS connectors and enhance the deformation ability of the steel–concrete interface. In order to investigate the shear mechanism of RSS connectors in the steel–concrete interface of cable-pylon composite anchorage, the segmental model test and Finite Element (FE) analysis were carried out. The connector shear force, steel–concrete relative slip and concrete pylon stress under typical RSS connector layouts were discussed. Research results show that the maximum shear force of stud connectors in the actual pylon could be decreased by 20% when RSS connectors are adopted in the steel–concrete interface. RSS connectors possess better deformation ability so that the strain difference between two shank sides of the RSS connector is significantly greater than that of the OHS connector. Furthermore, the shear mechanism of RSS connectors is affected by their layouts in the steel–concrete interface. The peak connector shear force can be respectively reduced by 14.3%, 28.8% and 33.7% when RSS connector ratio λ (i.e. ratio of RSS connector number to total connector number) equals to 0.28, 0.50 and 0.72 compared with λ = 0. The shear force range of stud connectors is simultaneously decreased. When the RSS connector ratio equals 0.72, the longitudinal and vertical slip ability are respectively raised by 22.5% and 25.0% compared with λ = 0. © 2020 Elsevier Ltd","Cable-pylon composite anchorage; Connector layouts; Rubber-Sleeved Stud connector; Segmental model test; Shear mechanism; Steel-concrete composite bridge; Steel-concrete interface","Anchorages (foundations); Cables; Connectors (structural); Deformation; Rubber; Stiffness; Studs (structural members); Concrete interface; Deformation abilities; Maximum shear forces; Research results; Shear mechanisms; Shear stiffness; Steel-concrete interface; Stud connectors; Concretes; composite; concrete; deformation; finite element method; interface; shear strength; steel; stiffness; structural component",,,,,,,,,,,,,,,,"Viest, M., Investigation of stud shear connectors for composite concrete and steel T-beams (1956) J Am Concr Inst, 27, pp. 875-891; Ollgaard, J.G., Slutter, R.G., Fisher, J.W., Shear strength of stud connectors in lightweight and normal-weight concrete (1971) AISC Eng J, 8, pp. 55-64; Oehlers, D.J., Coughlan, C.G., The shear stiffness of stud shear connections in composite beams (1986) J Constr Steel Res, 6, pp. 273-284; Pallarés, L., Hajjar, J.F., Headed steel stud anchors in composite structures, Part I: Shear (2010) J Constr Steel Res, 66, pp. 198-212; Liu, R., Liu, Y., Analysis of auxiliary ribs in steel-concrete joint of hybrid girder (2015) J Constr Steel Res, 112, pp. 363-372; Kim, S.E., Nguyen, H.T., Evaluation of the connection efficiency of hybrid steel-concrete girder using finite element approach (2012) Int J Mech Sci, 61, pp. 8-23; Lin, Z., Liu, Y., He, J., Static behaviour of lying multi-stud connectors in cable-pylon anchorage zone (2015) Steel Compos Struct, 18, pp. 1369-1389; Shuangjie Zheng, Yuqing Liu, Haijun Xu, Connection behavior of cable-pylon anchorage with steel bracket and anchor beam.

The respective algorithms for natural vibration frequency and vibration mode are established through the separation of variables. In the case of the three-pylon suspension bridge, the effect of the along-bridge bending vibration of the middle pylon on the vertical bending vibration of the entire bridge is considered. The impact of torsional vibration of the middle pylon about the vertical axis on the torsional vibration of the entire bridge is also analyzed in detail. The feasibility of the proposed method is verified by two engineering examples. A comparative analysis of the results obtained via the proposed and more intricate finite element methods confirmed the former feasibility. Finally, the middle pylon stiffness effect on the vibration frequency of the three-pylon suspension bridge is discussed. It is found that the vibration frequencies of the first- and third-order vertical bending and torsional modes both increase with the middle pylon stiffness. However, the increase amplitudes of third-order bending and torsional modes are relatively small with the middle pylon stiffness increase. Moreover, the second-order bending and torsional frequencies do not change with the middle pylon stiffness.

Finally, the analytical models of natural frequencies of the bridge-type amplifier and the compliant platforms were verified using the finite element analysis (FEA) method.

For these structures, structural analysis using FEM requires a reliable definition of the main mechanical properties of the materials constituting them and, in particular, a description of the actual damage state, which is a product of the damage they have suffered over the years. A general representation of material properties, including damage effects, can be performed by investigating the ""global modulus (E)""of a structure. This can be determined by experimental determination of fundamental frequencies with an experimental analysis and the use of Rayleigh expressions. In this paper, referring to a practical case of a reinforced concrete Gerber beam with an advanced state of degradation, a static checkup was made using dynamic characterization. The state of the structure and its degradation due to corrosion and carbonation effects was analyzed using nondestructive and partially destructive tests. Moreover, dynamic tests were also performed to determine the fundamental frequencies (environmental trembling) to be used, through the Rayleigh method, to determine the global modulus of the structures, necessary for structural analysis. Then, a retrofitting design was designed and applied with partial reconstruction of the concrete deck by using high-performance concrete and by externally wrapping the main and secondary RC beams with carbon fiber-reinforced plastic (FRP) strips and wraps. Finally, a dynamic test was carried out to verify the efficiency of the retrofitting system adopted. © 2020 American Society of Civil Engineers.","Bridge retrofitting; Damage detection; Dynamic identification; In situ tests; Rayleigh's method","Bridges; Carbon fiber reinforced plastics; Concrete beams and girders; Corrosion; Graphite fibers; High performance concrete; Natural frequencies; Retrofitting; Structural analysis; Degradation analysis; Dynamic characterization; Experimental analysis; Experimental determination; Experimental investigations; Fundamental frequencies; Partially destructive tests; Rayleigh expression; Fiber reinforced concrete",,,,,,,,,,,,,,,,"(2013) Aci Concrete Practices Non Destructive Testing: Covermeters, , ACI (American Concrete Institute).

Such systems offer several system-level advantages such as participation in demand response programs, demand charge reduction, arbitrage to maximize time-of-use rates, and increase resilience. For efficient and cost-effective integration of ES with RES, a Multi-Port Converter (MPC) is highly desirable. An isolated Triple Active Bridge (TAB) converter for Solar Photovoltaic (PV) and battery (ES) integration is discussed in this paper. Multi-objective optimization of this topology, for interfacing 10 kVA PV-ES system with 240 V AC grid, is conducted with the objectives to reduce losses and overall volume of the MPC.

The DAB converter is the key component of the SST. In this study, a new loosely coupled resonant DAB (LCR-DAB) that utilizes loosely coupled inductive power transfer (IPT) coils instead of the high frequency (HF) transformers of the conventional DABs is proposed. Unlike the HF transformers, a large air-gap between the primary and secondary coils enables easier packaging and high voltage insulation of the LCR-DAB. Series-series (SS) compensated symmetric resonant tanks are selected for the proposed IPT system. The dependences of the input impedance, efficiency, and power transfer direction of the proposed LCR-DAB on the phase-shift angle and the circuit parameters are investigated. Using the theoretical analysis, a circuit parameter design method for the LCR-DAB is proposed. Also, a new design approach for low-loss coils of the LCR-DAB are investigated using finite element analysis results. The proposed LCR-SST topology was evaluated using circuit simulation results. The simulated coil-to-coil efficiency of the LCR-DAB was 99 % over a 3-cm air-gap and the DC-to-DC efficiency of a 4-level LCR-SST was 94.5 %. © 2020 IEEE.","DAB converter; Inductive power transfer; Solid-state transformer; Wireless power transfer","Circuit simulation; DC-DC converters; Electric network parameters; Energy conversion; Energy transfer; Fading (radio); HVDC power transmission; Circuit parameter; Design approaches; Dual active bridge converter; Dual active bridges; High frequency HF; High voltage insulation; Loosely coupled inductive power transfer; Solid state transformer (SST); DC transformers",,,,,"Ministry of Land, Infrastructure and Transport, MOLIT","ACKNOWLEDGMENT This work was supported by a grant (20RTRP-B146050-03) from the Railroad Technology Development Program funded by Ministry of Land, Infrastructure and Transport (MOLIT) of Korean Government.",,,,,,,,,,"Abad, G., (2016) Power Electronics and Electric Drives for Traction Applications, , Wiley; Falcones, S., Mao, X., Ayyanar, R., Topology comparison for solid state transformer implementation (2010) Ieee Pes General Meeting, pp. 1-8. , Providence, RI, USA, Jul; Shi, J., Gou, W., Yuan, H., Zhao, T., Huang, A.Q., Research on voltage and power balance control for cascaded modular solid-state transformer (2011) Ieee Trans.

To investigate the causes, three main factors associated with structural design, material design, and construction are reviewed. Specifically, the bridge performance under thermal and construction loading is investigated by conducting a nonlinear finite-element analysis. The analysis parameters include bridge deck geometry, boundary conditions, bearing details, and skew angles. The loading conditions mainly include thermal and differential deck movements induced during an SPMT move. The results are compared to a crack map created from two site visits. It is concluded that skewed decks are more susceptible to cracking than straight decks due to an asymmetric expansion and contraction. Additionally, semi-integral abutment designs in a skewed bridge increase the extent of cracking in the skewed corners of the abutment ends. It is recommended that a semi-integral abutment design be carefully considered when designing a skewed bridge and that bearing and expansion joint details need careful attention for accelerated bridge construction. © 2020 American Society of Civil Engineers.","Accelerated bridge construction (ABC); Bearing; Cracking; Finite-element analysis; Self-propelled modular transporters (SPMT); Skewed bridge; Thermal","Expansion; Structural design; Accelerated bridge constructions; Bridge performance; Construction loading; Expansion and contraction; Loading condition; Material designs; Non-linear finite-element analysis; Semiintegral abutments; Abutments (bridge)",,,,,,,,,,,,,,,,"Anusreebai, S., Krishnachandran, V., Effect of reinforcement pattern on the behaviour of skew slab (2016) Int.

Fatigue damage evaluations of bridge weldments for the OSBs have been performed by many researchers for different loading scenarios and environmental conditions. During an extreme flooding event after many years of scour effects on bridge foundation, the foundation might fail and trigger the failure of the entire bridge. Many researchers have evaluated the effects of scour on the modal frequencies to monitor the depth of the foundation scour. For different dynamic characteristics of the bridges considering different soil and foundation conditions, it is not clear how the local stresses at the weld joints might be affected. In the present study, fatigue damage assessments of the bridge weld joints for the OSBs are conducted with the consideration of foundation scour of the bridges. First, a short span OSB is modeled in multiple length scales to balance computational costs and accuracy. The bridge welds are simulated in detail to capture the possible dynamic effects at these local structural details under different vehicle loadings. Soil springs are applied for the pile foundation, and the scour is simulated by releasing the soil springs. Using the hotspot stress method and the effective notch stress method, the revised equivalent stress ranges at the toe-deck crack, deck panel crack, floor beam crack, trough web crack, and root-deck crack are calculated. Based on the accumulated fatigue damages, reliability assessments of these cracks at different scenarios are performed. The fatigue life of the OSB is controlled by the cracks initiated at the floor beam-to-deck joints and the floor beam-to-rib joints. Considering foundation scour, the fatigue life of the weld joints is reduced by 22% at the maximum. The deterministic approach proposed in the specification is also used to predict the fatigue life of the weld joints. By introducing the effects of foundation scour, the fatigue life of the OSBs can be estimated more accurately. © 2020 American Society of Civil Engineers.","Deterministic approach; Effective notch stress method; Fatigue reliability analysis; Finite element analysis; Foundation scour; Hotspot stress method; Orthotropic steel bridges","Cracks; Damage detection; Fatigue damage; Floors; Foundations; Life cycle; Piles; Soils; Soldered joints; Springs (components); Steel bridges; Welds; Accumulated fatigue damage; Deterministic approach; Dynamic characteristics; Effective notch stress; Environmental conditions; Fatigue damage accumulation; Fatigue damage assessment; Reliability assessments; Scour",,,,,,,,,,,,,,,,"(2012) AASHTO LRFD Bridge, , AASHTO.

This article presents a methodology for the selection of sensors and their arrangement for detecting seismic damage in an in-service steel plate girder bridge system. In this study, a detailed span-based model was developed for the finite element simulation including the effect of the rubber bearing and piers, and the damage control by the side blocks. The finite element dynamic simulation was carried out with input earthquake acceleration to investigate the seismic behavior and grasp the damageable parts during an earthquake. Based on the results of finite element dynamic simulation, a fault tree analysis was carried out to reveal more about the bridge behavior, the failure modes, and the occurrence of damage. It was found that the side block, the bearing stiffener, and the horizontal bracing on the fixed side of the bridge are most important to be monitored for the evaluation of soundness of a plate girder bridge immediately after an earthquake. Finally, a sensor arrangement for the bridge was proposed based on the analysis results. © The Author(s) 2020.","earthquake damage; fault tree analysis; Plate girder; rubber bearing; seismic response analysis; sensor placement","Bearings (structural); Bridge components; Damage detection; Fault tree analysis; Faulting; Finite element method; Nonmetallic bearings; Plate girder bridges; Rubber; Seismic response; Structural analysis; Earthquake damages; Plate girder; Rubber bearing; Seismic response analysis; Sensor placement; Earthquakes",,,,,,,,,,,,,,,,"Aye, M.N., Kasai, A., Shigeishi, M., An investigation of damage mechanism induced by earthquake in a plate girder bridge based on seismic response analysis: case study of Tawarayama bridge under the 2016 Kumamoto earthquake (2018) Advances in Civil Engineering, 2018, pp. 1-19; Bruneau, M., Performance of steel bridges during the 1995 Hyogoken-Nanbu (Kobe, Japan) earthquake-a North American perspective (1998) Engineering Structures, 20 (12), pp. 1063-1078; Cho, S., Yun, C.B., Lynch, J.P., Smart wireless sensor technology for structural health monitoring of civil structures (2008) Steel Structures, 8, pp. 267-275; Christensen, R.M., Observations on the definition of yield stress (2008) Acta Mechanica, 196 (3-4), pp. 239-244; Filipov, E.T., Revell, J.R., Fahnestock, L.A., Seismic performance of highway bridges with fusing bearing components for quasi-isolation (2013) Earthquake Engineering & Structural Dynamics, 42 (9), pp. 1375-1394; Hsu, Y.T., Fu, C.C., Seismic effect on highway bridges in Chi Chi earthquake (2004) Journal of Performance of Constructed Facilities, 18 (1), pp. 47-53; Ishihara, K., Matsumura, M., Yoshida, M., Knock-off effect of steel side block as displacement restrainers on dynamic response of isolated bridge structure (2011) Procedia Engineering, 14, pp. 2341-2349; Itani, A.M., Bruneau, M., Carden, L., Seismic behavior of steel girder bridge superstructures (2004) Journal of Bridge Engineering, 9 (3), pp. 243-249; (2018) Bridges Yearbook Database, , www.jasbc.or.jp/kyoryodb/index.cgi, (accessed 3 December 2018; (2004) Handbook of Road Bridge Bearing, , Tokyo, Japan, Japan Road Association; (2012) Specifications for Highway Bridges Part 5 Seismic Design, , Tokyo, Japan, Japan Road Association; Jara, J.M., Raya, G., Olmos, B.A., Applicability of equivalent linearization methods to irregular isolated bridges (2017) Engineering Structures, 141, pp. 495-511; Kawashima, K., Unjoh, S., The damage of highway bridges in the 1995 Hyogo-ken Nanbu earthquake and its impact on Japanese seismic design (1997) Journal of Earthquake Engineering, 1 (3), pp. 505-541; Koto, Y., Konishi, T., Sekiya, H., Monitoring local damage due to fatigue in plate girder bridge (2019) Journal of Sound and Vibration, 438, pp. 238-250; Kozak, D.L., LaFave, J.M., Fahnestock, L.A., Seismic modeling of integral abutment bridges in Illinois (2018) Engineering Structures, 165, pp. 170-183; Matsumoto, K., Bridge monitoring system for Tokyo Gate Bridge (2012) Bridge Foundation Engineering, 46 (9), pp. 37-40; Matusevich, A.E., Massa, J.C., Mancini, R.A., Computation and uncertainty evaluation of offset yield strength (2013) Journal of Testing and Evaluation, 41 (2), pp. 217-230; Monzon, E.V., Buckle, I.G., Itani, A.M., Seismic performance and response of seismically isolated curved steel I-girder bridge (2016) Journal of Structural Engineering, 142 (12), p. 04016121; Murakoshi, J., Takahashi, M., Yoshioka, T., A study on application of FEM analysis to the design of steel girder bridge (2004) Steel Construction Engineering, 11 (43), pp. 131-145; Mustafa, S., Matsumoto, Y., Yamaguchi, H., Vibration-based health monitoring of an existing truss bridge using energy-based damping evaluation (2018) Journal of Bridge Engineering, 23 (1), p. 04017114; Nazmy, A.S., Seismic analysis and design evaluation of continuous plate-girder bridges: a case study (2003) International Journal of Structural Stability and Dynamics, 3 (1), pp. 91-106; Overschee, P.V., Moor, B.D., Subspace algorithms for the stochastic identification problem (1993) Automatica, 29 (3), pp. 649-660; Ren, W.-X., Zatar, W., Harik, I.E., Ambient vibration-based seismic evaluation of a continuous girder bridge (2004) Engineering Structures, 26 (5), pp. 631-640; Siringoringo, D.M., Fujino, Y., System identification applied to long-span cable-supported bridges using seismic records (2008) Earthquake Engineering & Structural Dynamics, 37 (3), pp. 361-386; Takahashi, Y., Hoshikuma, J.-I., Damage to road bridges induced by ground motion in the 2011 Great East Japan earthquake (2013) Journal of JSCE, 1 (1), pp. 398-410; Usami, T., Lu, Z., Ge, H., Seismic performance evaluation of steel arch bridges against major earthquakes.

But its superiority is not fully utilized in some occasions, where the operating ambient temperature is high, the cooling system is constricted, the high power density and decreased size is needed. In this paper, the thermal coupling effect which is vital to further improving the SiC power module in mentioned occasions is investigated by physical analytical derivation and finite element method (FEM) analysis at first. Several designing guidelines for SiC power module are presented at the view of attenuating thermal coupling effect. According to designing guidelines, a SiC-based, half bridge power module using the novel packaging structure called interleaved double-sided packaging structure is proposed. Due to the low thermal coupling effect and more balanced temperature distribution, this module features excellent thermal performance. © 2020 IEEE.","double-sided cooling; high temperature; power module; SiC device; Thermal coupling; thermal performance","Bridges; Electric power systems; Energy gap; Silicon; Silicon carbide; Silicon compounds; Double sided; Finite element method analysis; High power density; Packaging structure; Power module; Silicon devices; Thermal coupling; Thermal Performance; Wide band gap semiconductors",,,,,,,,,,,,,,,,"Neudeck, P.G., Okojie, R.S., Chen, L.Y., High-temperature electronics-A role for wide bandgap semiconductors?

Compared to the extensive research that has been conducted on the dynamic behavior of cable-supported bridges, the approach used by the mathematicians appears too simplistic. This is due to the fact that the dynamic force considered by the mathematicians is approximate compared to actual dynamic loadings on bridges, especially those originating from wind. However, they raise a point that is not considered in the wind design of cable-supported bridges, i.e., a possible nonlinear structural coupling between the modes of vibration that could be detrimental to the bridge performance. Therefore, this paper presents a preliminary investigation of nonlinear vertical-torsional coupling in long-span bridges using a simplified practical approach. The proposed method relies on the finite element method and nonlinear pushover analyses. Using this approach, the nonlinear structural coupling is assessed for the numerical models of five suspension bridges and two cable-stayed bridges. The method allows determining the nonlinear stiffness parameters of equivalent systems having between one and three degrees of freedom (lateral, vertical and torsional). Since the proposed technique relies on the modes of vibration and can account for the interaction between the vertical and torsional effects, it can be used to judge which ones of the bridges considered are likely to be the most susceptible to nonlinear mode coupling under wind loads. The analysis results for the seven bridges shows that the suspension bridge system has a greater nonlinear vertical-torsional coupling in comparison to the cable-stayed system. Additionally, it is demonstrated that the span length has an influence on the vertical-torsional coupling. The results also show that the nonlinear coupling is slightly affected by lateral effects. © 2020 Elsevier Ltd","Cable-stayed bridge; Cable-supported bridge; Finite element analysis; Geometric nonlinearities; Modes of vibration; Nonlinear static analysis; Structural dynamics; Suspension bridge","Cables; Degrees of freedom (mechanics); Dynamic loads; Structural dynamics; Suspension bridges; Suspensions (components); Vibrations (mechanical); Cable-supported bridges; Geometric non-linearity; Mathematical representations; Non-linear pushover analysis; Non-linear stiffness; Nonlinear mode coupling; Nonlinear structural couplings; Three degrees of freedom; Cable stayed bridges; bridge; dynamic response; loading; stiffness; torsion; vibration",,,,,"Università degli Studi Roma Tre; Compute Canada; Natural Sciences and Engineering Research Council of Canada, NSERC; Fonds de recherche du Québec – Nature et technologies, FRQNT; Mitacs","The financial support of the Natural Sciences and Engineering Research Council of Canada (NSERC), the Fonds de recherche du Québec - Nature et technologies (FRQNT), the ministère des Transports du Québec and Mitacs was greatly appreciated for the realization of this research project.

Through detailed discussion on existing research, influence factors of the ultimate shear capacity of the keyed dry joint are analyzed, a new shear capacity formula was proposed and evaluated. The feasibility and correctness of the FE simulation method were verified by comparison with the existed experimental results. Concrete tensile strength at the key root is critical to the ultimate bearing capacity of the single-keyed dry joint under the direct shear loading. Friction on the joint interface and dimension parameters of the key do not have much effect on the ultimate shear capacity. However, reasonable key inclination (tan?) would be suggested as 0.7~0.9. In comparison with the predicted results obtained by other existed formulas, the proposed formula is demonstrated to be in perfect consistency with both tests and the FE simulation results. © 2020 by the authors.","influencing factors; nonlinear finite element analysis; segmental precast bridge; shear capacity; single-keyed dry joint",,,,,,"2019JJ40385; University of Tennessee, UT","This research was funded by Natural Science Foundation of Hunan Province, Grant number 2019JJ40385.

There are six key parts in this paper. Firstly, the approximate analytical solution for funicular axis of arches subjected to the multi-pattern distributed load is derived from the approximations of linear elastic bending moment and horizontal reaction force in the arch end. Secondly, the numerical solution of the in-plane non-linear elastic equilibrium equation is solved by using the shooting method and the bisection method simultaneously. Thirdly, the approximate analytical solutions for the in-plane non-linear elastic equilibrium are derived according to the approximate analytical solution for funicular arch axis obtained from the first part, the simplified strain-displacement expression in Cartesian coordinate system and the virtual work principle. Fourthly, a key parameter is proposed to transform the approximate analytical solutions into the corresponding equations of catenary and parabolic arches. Fifthly, the in-plane non-linear elastic symmetric and asymmetric buckling of arches under the multi-pattern distributed load is derived analytically. Lastly, the in-plane non-linear elastic buckling behaviors of arches subjected to multi-pattern distributed load are deduced based on the obtained analytical solutions. The multi-pattern distributed load with the uniformly distributed load along the span and the uniformly distributed load along the arch is selected as example to verify the proposed method. Comparisons with numerical solutions demonstrate that the proposed approximate analytical solutions for the funicular arch axis and linear elastic horizontal reaction force agree well with the results of Runge-Kutta method and the proposed approximate buckling predictions have sufficient accuracy compared with the results of finite element method in different rise-to-span ratios, relative slenderness and arch axis parameters. © 2020 Elsevier Ltd","Cartesian coordinate system; Funicular arch axis; Multi-pattern distributed load; Non-linear elastic buckling; Non-linear strain-displacement expression","Arches; Buckling; Differential equations; Horizontal wells; Loads (forces); Numerical methods; Runge Kutta methods; Approximate analytical methods; Approximate analytical solutions; Cartesian coordinate system; Horizontal reaction forces; Non-linear elastic stability; Numerical solution; Strain displacement; Virtual work principle; Arch bridges",,,,,"20141BBG70089; National Natural Science Foundation of China, NSFC: 11772129, 51568020","This work was financially supported by National Natural Science Foundation of China (No. 51568020 , No. 11772129 ) and Science and Technology Plan in Jiangxi Province ( 20141BBG70089 ).",,,,,,,,,,"Chen, B.C., Wang, T.L., Overview of concrete filled steel tube arch bridges in China (2009) Journal of Practice Periodical on Structural Design and Construction, ASCE, 14, pp. 70-80; Zheng, J.L., Wang, J.J., Concrete-filled steel tube arch bridges in China (2018) Engineering, 4, pp. 143-155; Pi, Y.-L., Bradford, M.A., Uy, B., In-plane stability of arches (2002) Int.

Although continuing operation without inspection may be dangerous for motorway users, unnecessary interruption may have adverse consequences, especially with respect to rescue operations. This calls for development and implementation of a RApid REsponse (RARE) system, which will facilitate rationalized decisions. Such system requires real-time assessment of the seismic damage of motorway infrastructure, including which bridges are arguably the most vulnerable. This study addresses the issue by combining nonlinear finite element (FE) simulations with advanced econometric modeling. Based on a published simplified modeling approach and classification schemes, simplified FE models of characteristic bridge categories are developed, accounting for key structural components (pier, deck, abutment bearings, abutment stoppers) and soil-structure interaction. Employing the three-stage least squares (3SLS) approach, the data from the FE analyses are used to develop a relationship among the seismic damage (using the maximum and residual drift ratio, and the ratio of maximum ductility demand over ductility capacity as damage indices) of the bridge and the statistically significant intensity measures. The proposed 3SLS approach accounts for (1) both simultaneous equation bias and cross-equation contemporaneous correlation of the disturbances (error terms) caused by shared unobserved effects across the damage indices; (2) endogeneity among the damage indices with the use of instrumental variables; and (3) unobserved heterogeneity and panel effects, through the use of fixed effects. The 3SLS approach is compared to a traditional ordinary least squares (OLS) regression, and the comparison depicts the superiority of 3SLS in terms of explanatory power and forecasting accuracy. © 2020 American Society of Civil Engineers.","Bridges; Finite element simulations; Nonlinear; Seismic damage; Three-stage least squares","Abutments (bridge); Ductility; Earthquake effects; Highway bridges; Soil structure interactions; Structural analysis; Classification scheme; Instrumental variables; Non-linear finite elements; Ordinary least squares; Seismic damage assessment; Simultaneous equations; Three-stage least squares; Unobserved heterogeneity; Damage detection; bridge; earthquake damage; finite element method; least squares method; real time; risk assessment; structural component",,,,,,,,,,,,,,,,"Agalianos, A., Sakellariadis, L., Anastasopoulos, I., Simplified method for the assessment of the seismic response of motorway bridges: Longitudinal direction-Accounting for abutment stoppers (2017) Bull.

Taking into account geometric and material nonlinearity, nonlinear finite-element analysis of a simple supported truss bridge was carried out to exhibit effects of different types of initial imperfections. A half-wave of initial imperfection was proved to be effective in the nonlinear buckling analysis. And a parameter analysis of initial imperfections was also conducted to reveal that the upper chords have the greatest impact on the buckling, followed by the bottom chords, vertical and diagonal web members. Yet initial imperfections of transverse beams have almost no effect on the buckling. Moreover, using influence surface method, the combinatorial effects of initial imperfections were compared to demonstrate that initial imperfections of the upper chords play a leading role. Furthermore, the equivalent effective length coefficients of the upper chord were derived to be 0.2-0.28 by different methods, which implies vertical and diagonal web members still provide effective constraints for the upper chord despite a lack of the upper transverse connections between the two upper chords. Therefore, the geometrical and material nonlinear finite-element method is effective in the buckling analysis due to its higher precision. Based on nonlinear analysis and installation deviations of members, initial imperfection of l/500 is recommended in the nonlinear analysis of half-through truss bridges without initial imperfection investigation. © 2020 Techno-Press, Ltd.","Aluminum alloy bridge; Half-through truss bridge; Influence surface; Nonlinear; Stability","Buckling; Finite element method; Trusses; Diagonal web member; Effective constraints; Effective length coefficient; Geometric and material nonlinearities; Initial imperfection; Non-linear finite-element analysis; Non-linear stabilities; Nonlinear buckling analysis; Nonlinear analysis",,,,,"Fundamental Research Funds for the Central Universities: 2017XKQY050","The authors wish to express their gratitude and sincere appreciation to Fundamental Research Funds for the Central Universities (2017XKQY050) for financing this research work.",,,,,,,,,,"(2014) AASHTO LRFD Bridge Design Specifications, , AASHTO (7th Ed), American Association of State Highway and Transportation Officials; Washington DC, USA; (2010) Specification for Structural Steel Buildings, , ANSI/AISC 306-10 American Institute of Steel Construction; Chicago, USA; Birajdar, H.S., Maiti, P.R., Singh, P.K., Strengthening of Garudchatti bridge after failure of Chauras bridge (2016) Eng.

In design codes of most of the countries, impact factor is provided as a function of bridge length or fundamental natural frequency. However, many studies recently conducted on bridge vehicle dynamics found other influencing parameters for the impact factor. In the present paper, the dynamic amplification factor of the steel truss girder bridge has been found out taking bridge–vehicle dynamics using finite element method. An uncoupled iterative scheme interfacing the finite element software has been proposed to implement vehicle induced pavement force.

Previous studies on intermediate anchorages have two major limitations: improper adoption of results obtained from studies on end anchorages and neglecting to account for the beneficial effect from lateral stress overlapping. Through load path modeling, finite-element modeling, and experimental testing, this study provides new insight into this common problem. For the single-load case, a load path model is established to capture the flow of forces in the intermediate anchorage zone, from which an explicit equation for the distribution of transverse stresses is derived. For the multiple-load case, an analytical method is proposed to evaluate the splitting effects in slabs with different load spacings. The analytical method is applied to predict slab splitting in prefabricated composite beams. Four prefabricated composite box girders with different spacings of stud clusters were tested and used to verify the proposed analytical method. Furthermore, the analytical method was applied to predict the splitting effect in pylon anchorages of cable-stayed bridges, and the results compared with results of finite-element analysis using shell elements. It is found that the splitting force equation for the end anchorage zone would significantly overestimate the splitting effect in slabs with closely spaced intermediate loads. In composite girders with precast concrete deck, only the front halves of transverse rebars in intervals between shear pockets are effective to protect the slab from longitudinal splitting failure. © 2020 American Society of Civil Engineers.","Concrete slab; Intermediate anchorage; Splitting; Transverse stress","Anchorage zones; Anchorages (foundations); Box girder bridges; Cable stayed bridges; Cables; Composite beams and girders; Concrete beams and girders; Loads (forces); Precast concrete; Beneficial effects; Composite box girder; Engineering structures; Experimental testing; Explicit equations; Multiple load case; Precast concrete deck; Steel-concrete composite girders; Finite element method",,,,,"2017YFC0703402","This study was supported by the National Key R&D Program of China (Grant No. 2017YFC0703402)",,,,,,,,,,"(2017) AASHTO-LRFD bridge design specifications, , AASHTO. 8th ed.

The one-dimensional model is favoured over the three-dimensional model due to its simplicity and cost-effectiveness during the initial design and analysis phase of the box-girder bridge. The complex structural actions of thin-walled box-girders such as torsional warping and cross-sectional distortion are taken into consideration in addition to extension, bending and torsion. Keeping in mind these complex actions, the beam element incorporates three extra degrees of freedom in addition to the familiar six degrees of freedom per node. MATLAB coding is done to obtain various response parameters for single as well as double cell box girders. Furthermore, the variation of different response parameters due to changes in radius, span length, load position, varying cross-section and various combinations of Indian rail loads has also been studied. The finite element approach used in this study is validated by solving two numerical examples which are in excellent agreement with the results of previous studies. © 2020, Springer Nature Switzerland AG.","Box-girder bridge;

Carbon fiber-reinforced polymer (CFRP) laminate external retrofit is a viable option for regaining such bent cap capacity and serviceability. In this study, a three-dimensional numerical modeling of significantly deteriorated bent caps from a 78-year old cast-in-place bridge in Forney, Texas, was performed. The purpose was to determine the effectiveness of the repair and strengthening process. Numerical models of the bent caps in the original undamaged, damaged, epoxy mortar repaired and CFRP strengthened states were created and calibrated using strain data obtained from full-scale live load testing. The calibrated model strains showed good agreement with those from the load testing. With short span lengths and deep sections, the model strains were small and the effect of the repair/strengthening at modest levels. The neutral axes of the bent cap sections, found from numerical modeling, moved slightly downward after the repair/strengthening process. The model with no section loss showed the highest tensile capacity, and subsequent levels of concrete spalling resulted in progressively smaller capacity. After the first crack initiation, inelastic behavior set in along with crack opening, which explains the increased rate of strains. Truck live loads were adequately represented in the developed numerical models. © 2020, Springer Nature Switzerland AG.","Bridge bent caps; CFRP strengthening; Deep beams; Finite element analysis; Numerical modeling",,,,,,"Texas Department of Transportation, TxDOT: 0896543245; University of Texas at Arlington, UTA","The study reported herein was performed at UT Arlington under a contract from the Texas Department of Transportation (TxDOT) (Grant Number 0896543245).",,,,,,,,,,"(2014) Version 6.14, vol I–III.

First, laboratory investigations were conducted to calibrate the material models of durable concrete. Second, the material models were utilized in several member level FEM models and the simulation procedure was verified regarding early age volume changes calibrating parameters for expansion energy and reduction factors for creep. Third, thermal and volumetric changes in RC slab were monitored and the simulation procedure was further validated in structural level utilizing full-scale FEM model of the real bridge. The simulated maximum tensile stress along bridge axis in RC slab signify the risk of early age transverse cracking where the accumulated stepping construction stress is comparatively large. The effectiveness of expansive additive in reducing the risk of transverse cracking is revealed from the simulation. However, parametric studies of the validated model indicate that the RC slab on the permanent form of seven span steel box girder bridge is vulnerable to early age thermal cracking regardless of ambient conditions and placing temperatures when coefficient of thermal expansion of concrete is larger than 6 × 10-6/℃. © 2020 Japan Concrete Institute",,"Additives; Beams and girders; Box girder bridges; Concrete placing; Cracking (chemical); Expansion; Slag cement; Slags; Steel bridges; Steel structures; Thermal expansion; 3d-fem simulations; Ambient conditions; Expansive additives; Laboratory investigations; Simulation procedures; Thermal stress simulation; Transverse cracking; Volumetric changes; Concretes",,,,,"Ministry of Land, Infrastructure, Transport and Tourism, MLIT","This research was carried out collaborating with “Tohoku Regional Development Bureau of MLIT, Japan” as “Research development on quality and durability attainment system for concrete structures in various regions utilizing curing techniques and admixtures”, the commissioned research of “National Institute for Land and Infrastructure Management” under technology research and development system of “The Committee on Advanced Road Technology” established by MLIT, Japan.",,,,,,,,,,"(2001) Control of cracking in concrete structures (ACI 224R-01), , ACI, Farmington Hills, MI: American Concrete Institute; Altoubat, S., Lange, D., Creep, shrinkage and cracking of restrained concrete at early age (2001) ACI Materials Journal, 98 (4), pp. 323-331; Alger, M.

Finite element analysis was carried out to compare theoretical strains with the experimental values and to finalize the location of strain gauges. The thrust force and torque were measured by eight strain gauges, each forming a Wheatstone bridge circuit, converting the deflections of elastic strain rings to proportional electrical signals. A suitable data acquisition system was used for recording the thrust and torque in a computer system. Calibration curves were plotted by applying known thrust and torque repeatedly.

The evaluation of the mechanical stress in the rotor is one crucial part of the design process for this type of machines. It is insufficient to evaluate just the static mechanical stress at maximum speed. The dynamic mechanical stress between the state of standstill and maximum speed needs to be considered as well to evaluate the high fatigue strength of the rotor.One criterion that is commonly used to analyze the dynamic load in a material is the Smith diagram. In this work, a new methodology is introduced to evaluate both, the dynamic and the static mechanical stress, in the rotor of an high speed electric machine. First, the von Mises stress criterion is used to examine the static mechanical stress in the rotor core. Then, the Smith diagram is used to evaluate the dynamic mechanical stress and the high fatigue resistant of the rotor.The methodology is then applied to a high speed electric machine with buried magnets in v-shape for analyzing the state of stress. Therefore, the state of stress is calculated using an FEM simulation model. It can be seen that high dynamic stress occurs at the bridges in the rotor.

High skew can also lead to stresses or displacements that adversely affect service performance. This paper demonstrates the effects of skew on bridges through finite element analyses, bridge inspections, and statistical analyses. Five deck-girder type bridges with and without skew were inspected. A database of more than 1,400 deck-girder type bridges was analyzed to seek relationships between skew and National Bridge Inventory (NBI) ratings. Practices of Departments of Transportation (DOT) were compared with each other and to provisions of AASHTO LRFD Bridge Design Specifications (BDS). Acute deck corner cracking and bridge movements were documented on some high-skew bridges. Field inspections and database analyses showed that not all high-skew bridges have performance issues, and NBI ratings are in general not sensitive to skew. This is likely because of many factors affecting performance and certain details mitigating skew effects. © National Academy of Sciences: Transportation Research Board 2020.",,"Inspection; Bridge inspection; Bridge movements; Bridge performance; Database analysis; Departments of transportations; Field inspection; Performance issues; Service performance; Bridges",,,,,"Federal Highway Administration, FHWA: 0092-16-05; State University of New York, SUNY; Wisconsin Department of Transportation, WisDOT","The authors would like to thank the Project Oversight Committee, Mr. John Bolka, Mr. Dale Weber of WisDOT, and Dr. Michael Oliva, professor emeritus of University of Wisconsin, Madison for their input.

There is a lack of knowledge on the long term performance and structural integrity of fire damaged and fiber reinforced polymer (FRP) laminate retrofitted bridges. One such rare in-service bridge was selected for this study. The fire damaged cast-in-place non-prestressed girders were previously repaired with mortar and strengthened with FRP wrapping. The girders were instrumented with strain gages and displacement transducers, and a non-destructive live load test was carried out to evaluate the structural response. The results from the load testing were used to compare two identical girder spans with and without CFRP strengthening. A full-scale non-linear finite element model of the overall bridge superstructure was created, and the test results used to calibrate the model. The carbon (CFRP) strengthened girder exhibited similar stiffness compared to the undamaged girder as evidenced by almost equivalent mid-span deflection. The girder moment capacity decreased significantly due to fire damage, and the CFRP strengthening plus mortar repair was successful in restoring the moment capacity. The finite element model provided good correlation with load test results. © 2020 American Concrete Institute.

The paper aims to discuss this issue. Design/methodology/approach: In this paper, the thermal bridge problem of special-shaped column structures is studied, T-shaped column composed of concrete-filled square steel tubes is taken as an example, the finite element thermal bridge model is established by ANSYS software, the heat treatment is calculated by the software and the results are output. Findings: According to the finite element results, it can be found that in the thermal bridge model, the temperature distribution is uniform, the heat flux density is small and the heat dissipation where the steel plate locates is serious. The lowest temperature of the thermal bridge is greater than the air condensation temperature, and the affected area is about 0.2 m, which is larger than the thickness of the wall and will not cause too much impact on the wall. It will help to suppress heat dissipation and achieve energy-saving and heat preservation inside the buildings. Originality/value: The experimental results prove the effectiveness of the special-shaped column structure for building energy-saving buildings. This study provides some theoretical basis for further application of special-shaped column structures in architecture. © 2019, Emerald Publishing Limited.","Finite element analysis; Heat dissipation; Heat preservation; Special shaped columns composed of concrete-filled square steel tubes; Thermal bridge effect","Bridges; Energy conservation; Heat flux; Historic preservation; Intelligent buildings; Tubular steel structures; Walls (structural partitions); Broad application; Building energy saving; Concrete-filled square steel tube; Design/methodology/approach; Heat flux densities; Heat preservation; Special-shaped column; Steel structure residential buildings; Concretes",,,,,,,,,,,,,,,,"Hajjar, J.F., Concrete-filled steel tube columns under earthquake loads (2015) Progress in Structural Engineering & Materials, 2 (1), pp. 72-81; Heidrich, O., Kamara, J., Maltese, S., Cecconi, F.R., Dejaco, M.C., A critical review of the developments in building adaptability (2017) International Journal of Building Pathology and Adaptation, 35 (4), pp. 284-303; Hu, Y., Zhao, P., Yang, B., Dai, G.X., Numerical study on temperature distribution of high-strength concrete-filled steel tubes subjected to a fire (2016) International Journal of Steel Structures, 16 (4), pp. 1057-1069; Huang, G.P., Study on macroseismic response of an special-shape concrete-filled-steel-tube arch bridge (2014) Applied Mechanics and Materials, 711, pp. 454-460; Ibrahim, M., Biwole, P.H., Wurtz, E., Achard, P., Limiting windows offset thermal bridge losses using a new insulating coating (2014) Applied Energy, 123, pp. 220-231; Larbi, A.B., Couchaux, M., Bouchair, A., Thermal and mechanical analysis of thermal break with end-plate for attached steel structures (2017) Engineering Structures, 131, pp. 362-379; Li, B., Guo, L., Li, Y., Zhang, T., Tan, Y., Thermal bridge effect of aerated concrete block wall in cold regions (2018) IOP Conference Series: Earth and Environmental Science, Vol. 108, p. 22041; Li, W.F., The study on promotion of chinese green energy-saving buildings (2014) Applied Mechanics and Materials, 672-674, pp. 1847-1850. , Vols; Lu, M.J., Thermal optimization strategy of external wall in low-rise light steel keel structure based on the theory of thermal bridge (2013) Advanced Materials Research, 671-674 (2), pp. 2150-2153. , Vols; Lu, M.J., Zheng, L.L., Analysis on exterior wall conformation of low-rise light steel structure residence based on thermal theory (2014) Applied Mechanics and Materials, 587-589, pp. 384-388. , Vols; Pi, F., Liu, Z., Yang, H., Research on seismic control of high rise steel frame building structure (2016) Journal of Computational and Theoretical Nanoscience, 13 (12), pp. 9898-9903; Rong, B., Feng, C.X., Zhang, R.Y., You, G.C., Liu, R., Compression-bending performance of L-shaped column composed of concrete filled square steel tubes under eccentric compression (2017) International Journal of Steel Structures, 17 (1), pp. 325-337; Tao, Z., Song, T.Y., Uy, B., Han, L.H., Bond behavior in concrete-filled steel tubes (2016) Journal of Constructional Steel Research, 120, pp. 81-93; Vladulescu, F., Structural-thermal analysis of welded joints using the ANSYS workbench platform (2018) Advanced Materials Research, 1146, pp. 17-21; Wang, W., Zhang, S.J., Pasquire, C., Factors for the adoption of green building specifications in China (2018) International Journal of Building Pathology and Adaptation, 36 (3), pp. 254-267; Wang, Y.W., Chen, Z.H., Zhou, T., Li, Y.B., Wang, X.D., Parametric analysis of special-shaped column composed of concrete-filled square steel tubes under cyclic loading (2014) Earthquake Engineering and Engineering Dynamics, 34 (3), pp. 126-132; Xie, Y.F., Li, C.X., Li, Z.H., Smart building materials of BIM and RFID in LifeCycle management of steel structure (2016) Key Engineering Materials, 723, pp. 736-740; Yazdian, N., Mohammadpour, M., Kong, F., Kovacevic, R., Hybrid laser/arc girth welding of 304L stainless steel tubes, part 1-pore mitigation, thermal analysis and mechanical properties (2018) International Journal of Pressure Vessels and Piping, 163, pp. 75-93; Zhou, T., Jia, Y.M., Xu, M.Y., Wang, X.D., Chen, Z.H., Experimental study on the seismic performance of L-shaped column composed of concrete-filled steel tubes frame structures (2015) Journal of Constructional Steel Research, 114, pp. 77-88; Zhou, T., Xu, M.Y., Wang, X.D., Chen, Z.H., Qin, Y., Experimental study and parameter analysis of L-shaped composite column under axial loading (2015) International Journal of Steel Structures, 15 (4), pp. 797-807","Wang, Z.; Luoyang Institute of Science and TechnologyChina; email: wzjzijing@yeah.net",,,"Emerald Group Holdings Ltd.",,,,,23984708,,,,"English","Int.

This bridge is located in the hinterland of the Qinling Mountains, Shaanxi Province, where the terrain is complicated. The excavation of the south abutment foundation broke the local rock masses and caused a few unloaded joints. Composite pile foundation and anchor cables combined with shotcrete anchor technology were proposed to strengthen the foundation. The displacements of the foundation before and after the reinforcement were calculated and compared using the finite element method. A layer-by-layer construction scheme was adopted to construct the arch ring because its cross-section was too large. Finally, the additional forces and displacement of the rail tracks were investigated through bridge–track interaction analyses. The effects of long-term shrinkage and creep on the longitudinal stress and displacement of the rail tracks were revealed for different construction schemes. The results provide significant engineering experience for the construction of solid-web reinforced concrete arch bridges. © 2019, © 2019 International Association for Bridge and Structural Engineering (IABSE).","bridge–track interaction; finite element method; High-speed railway bridge; layer-by-layer construction scheme; solid-web reinforced concrete arch bridge","Anchor cables; Arch bridges; Arches; Concrete construction; Finite element method; Pile foundations; Piles; Railroad bridges; Railroad tracks; Railroads; Rails; Reinforced concrete; Shrinkage; Composite pile foundations; Concrete arch bridges; Construction scheme; Construction technologies; High - speed railways; High-speed railway bridges; Interaction analysis; Shrinkage and creep; Railroad transportation",,,,,,"Muhe Bridge is a long-span solid-web RC arch bridge.

The entire construction process is simulated by the A-FEM with the mesh-separation-based approximation technique, while the degenerated plate elements are constructed based on 3D isoparametric elements, making it suitable for analysis of a thin-walled structure. This method significantly improves computational efficiency by avoiding numerous degrees of freedom (DoFs) when analyzing complex structures. With characteristics of the full-span erection technology, the end-face angle of adjacent girder segments, the preset distance of girder segments from the design position, and the temperature difference are selected as control parameters, and they are calculated through the structural response of each construction stage. Engineering practice shows that the calculation accuracy of A-FEM is verified by field-measured results.

However, little research has been conducted on the performance of the additional negative reinforcing steel. Requirements for the termination of the additional negative moment reinforcing steel have largely been based upon the engineering judgement, previous performance, and existing practice. The main objective of the research is to evaluate the effect of different amounts of b2 bars on resisting the negative moment over the pier on a continuous prestressed concrete girder bridge when it subject to the live load generated moment and secondary moment. To achieve this objective, a live load field test was performed on a bridge designed with different amounts of b2 bars to allow for comparison of the varying levels of negative moment reinforcement present. A full-scale finite element model was developed and validated against the field-collected data to study the b2 bar performance subjected to live loads. An evaluation was performed, utilizing an analytical approach by calculating the time-dependent secondary moment using mRESTRAINT and loading the beam-line FE model with the maximum negative moment. It was found that the negative moment induced by the live load and secondary moment does appear through the service life of the bridge. The high differential shrinkage rate between the fresh deck concrete and the girder concrete is the main source of the negative moment over the supports. The magnitude of the secondary moment was found to be highly influenced by the time when the continuity established. The results also indicated that the additional longitudinal reinforcing steel provides minimal effect on resistance to the negative moment prior to the formulation of deck cracking, regardless of whether the negative moment was induced by live loads or secondary moment. The current design approach determines the b2 bars requirement for the strength level based on the live load, it may be necessary to include the secondary moment in the design. © 2020 Elsevier Ltd","Additional negative moment reinforcing steel (b2 bar); Field test; Finite element modeling; Secondary moment","Concrete beams and girders; Finite element method; Prestressed concrete; Reinforcement; Shrinkage; Structural dynamics; Analytical approach; Differential shrinkage; Engineering judgement; Field test; Intermediate support; Longitudinal reinforcement; Reinforcing steels; Secondary moments; Bridges; bridge; concrete structure; cracking (fracture); finite element method; numerical model; reinforcement; structural response",,,,,,,,,,,,,,,,"(2012), AASHTO.

The finite element analysis of the wall pier is carried out by using the layered shell element, and its accuracy is verified through the comparison with the experimental results. A series of wall pier samples are generated based on the survey data, and the corresponding finite element models are established. The hysteresis analysis is implemented to obtain the displacement drift ratio of each seismic performance point. A candidate capacity model with various factors is proposed, and the unknown parameters are estimated and filtered by the Bayesian method. One hundred and twenty bridge samples of a benchmark bridge are generated by considering the uncertainty of parameters, and the finite element models are established. The bridge samples and ground motions were matched by one-to-one correspondence for the nonlinear time history analysis, and seismic vulnerability models of bridge components and system are obtained. The results showed that the in-plane capacity of wall piers is mainly affected by axial compression ratio, shear span ratio, and vertical reinforcement ratio. The wall pier shows excellent behavior in the earthquakes. The capacity models of wall piers can be used for evaluating the damage states of wall piers, and obtaining the seismic vulnerability model of wall piers bridges to be used for future seismic risk assessment and retrofit prioritization. © 2020 by the authors.","Bayesian method; Capacity model; Seismic vulnerability; Uncertainty; Wall pier bridge",,,,,,"National Natural Science Foundation of China, NSFC: 51308125; China Postdoctoral Science Foundation: 2014M561855","This research were funded by National Natural Science Foundation of China (grant number 51308125) and China Postdoctoral Science Foundation (grant number 2014M561855).

The study is performed with Ansys finite element software, which reads in batch mode programming a previously generated mesh data file and computes the transient dynamic solution for each time-step iteration within an analysis time range. Design/methodology/approach: The approach itself is applied on a bridge structure which can be potentially subjected to damage zones due to severe loads cases and or earthquakes vibrations. The ideal Von Mises failure criterion ellipsoid envelope is applied for the detection of overstepped computed stresses and strains. Findings: This numerical analysis allows computing, for each time-step iteration, the dynamic displacements at each degree of freedom and the corresponding stresses and strains inside the elements under the action of several times dependent loads cases. Practical implications: Several simulations are considered to quantify the external loads. Originality/value: The material properties of reinforced concrete RC are calculated for an existing specific bridge structure case. The RC strength is then introduced from the basic compounds material properties using the corresponding volumes fractions. © 2019, Emerald Publishing Limited.","Cracks; Damage zones detection; Finite element method; Mixture rules of materials; Reinforced concrete material properties; Strengths","Bridges; Concrete construction; Concrete mixtures; Cracks; Damage detection; Degrees of freedom (mechanics); Elasticity; Iterative methods; Reinforced concrete; Structural design; Ansys finite elements; Damage zones; Design/methodology/approach; Dynamic displacements; Mixture rules; Strengths; Structural monitoring; Transient dynamics; Finite element method",,,,,"Ministry of Higher Education and Scientific Research, MHE&SR; Ministry of Higher Education and Scientific Research, MHESR","The project presented in this paper is supported by the Built Environmental Research Lab., USTHB, Ministry of Higher Education and Scientific Research of Algeria.","The project presented in this paper is supported by the Built Environmental Research Lab., USTHB, Ministry of Higher Education and Scientific Research of Algeria.",,,,,,,,,"Bathias, C., (2009) Materiaux Composites, , Du; Chatelain, J.L., Guillier, B., Gueguen, P., Frechet, J., Sarrault, J., Ambient vibration recording for single-station, Array and building studies made simple, CityShark II (2012) International Journal of Geosciences, 3, pp. 1168-1175; Cook, R.D., (1989) Concepts and Applications of Finite Element Analysis, , John Wiley, New York, NY; Golgoon, A., Sadik, S., Yavari, A., Circumferentially-symmetric finite eigenstrains in incompressible isotropic nonlinear elastic wedges (2016) International Journal of Nonlinear Mechanics, 84, pp. 116-129; (2009) RCPR code: rules defining the loads to be applied for the calculation of the bridges roads trials, , MDTP; Moussaoui, M.L., Structural damage zones detection by finite elements (2018) FRACT’4 Conference, , Chlef: 26-29 November; Moussaoui, M.L., Chabaat, M., Kibboua, A., Damage detection in bridges using a mathematical model by an updating method (2013) The 4th Canadian Conference on Nonlinear Solid Mechanics, CanCNSM2013, , Montreal: 23-26 July; Moussaoui, M.L., Chabaat, M., Kibboua, A., Dynamic detection of reinforced concrete bridge damage by finite element model updating (2014) Journal of Mechanics Engineering and Automation, 4 (1), pp. 40-45. , doi:, David Publishing Company; Moussaoui, M.L., Kibboua, A., Chabaat, M., Contribution to bridge damage analysis (2015) Applied Mechanics and Materials Journal, 704, pp. 435-441. , doi:, Trans Tech Publications; (2005) Plans No 1 to 6 OA on Oued Oumazer over cw 109 EPE SAPTA, , DTP of Tipaza, MDTP; Geradin, M., (1993) Theorie des Vibrations, , Masson, Paris","Moussaoui, M.L.; Department of Mechanical Construction and Production, Algeria; email: mmoussaoui@usthb.dz",,,"Emerald Group Holdings Ltd.",,,,,17579864,,,,"English","Int.

The effectiveness of the 2D CSMM-based NLFE model has been compared with the widely used one-dimensional (1D) fiber-based NLFE models. Design/methodology/approach: Three reinforced concrete (RC) hollow rectangular bridge piers tested under reversed cyclic uniaxial bending and sustained axial loads at the National Centre for Research on Earthquake Engineering (NCREE) Taiwan have been simulated using both 1D and 2D models in the present study. The non-linear behavior of the bridge piers has been studied through various parameters such as hysteretic loops, energy dissipation, residual drift, yield load and corresponding drift, peak load and corresponding drift, ultimate loads, ductility, specimen stiffness and critical strains in concrete and steel. The results obtained from CSMM-based NLFE model have been critically compared with the test results and results obtained from the 1D fiber-based NLFE models. Findings: It has been observed from the analysis results that both 1D and 2D simulation models performed well in predicting the response of flexure critical bridge pier. However, in the case of shear critical bridge piers, predictions from 2D CSMM-based NLFE simulation model are more accurate. It has, thus, been concluded that CSMM-based NLFE model is more accurate and robust to simulate the complete non-linear behavior of shear critical RC hollow rectangular bridge piers. Originality/value: In this study, a novel attempt has been made to provide a rational and robust FE model for analyzing shear critical hollow RC bridge piers (with walls having aspect ratios greater than 2.5). © 2020, Emerald Publishing Limited.","Bridge pier; Cyclic softened membrane model; Load displacement curves; Non-linear finite element analysis; Reversed cyclic load","Aspect ratio; Bridge piers; Earthquake engineering; Energy dissipation; Forecasting; Reinforced concrete; Steel beams and girders; Stiffness; Textile fibers; Cyclic softened membrane models; Design/methodology/approach; Load-displacement curve; Non-linear finite elements; Non-linear finite-element analysis; Non-linear response; Robustness evaluation; Two Dimensional (2 D); Finite element method",,,,,,,,,,,,,,,,"(1995) Building Code Requirements for Reinforced Concrete (ACI 318-95) and Commentary, , American Concrete Institute, International Organization for Standardization; Bairan, J.M., Mari, A.R., Coupled model for the non-linear analysis of anisotropic sections subjected to general 3D loading, Part 1: theoretical formulation (2006) Computers and Structures, 84 (31), pp. 2254-2263; Bairan, J.M., Mari, A.R., Coupled model for the non-linear analysis of anisotropic sections subjected to general 3D loading, Part 2: implementation and validation (2006) Computers and Structures, 84 (31), pp. 2264-2276; Bathe, K.J., (2014) Finite Element Procedures, , PHI Learning, Delhi; Baumann, T., Zur frage der netzbewehrung von flachentragwerken (1972) Der Bauingenieur, 46 (6), pp. 367-377; Bazant, Z.P., Oh, B.H., Microplane model for progressive fracture of concrete and rock (1985) Journal of Engineering Mechanics, 111 (4), pp. 559-582; Bazant, Z.P., Ozbolt, J., Nonlocal microplane model for fracture, damage, and size effect in concrete structures (1990) Journal of Engineering Mechanics, 116 (11), pp. 2484-2504; Bazant, Z.P., Prat, P.C., Microplane model for brittle-plastic material, Parts I and II (1988) Journal of Engineering Mechanics, 114 (10), pp. 1672-1702; Belarbi, A., Hsu, T.T.C., Constitutive laws of concrete in tension and reinforcing bars stiffened by concrete (1994) Structural Journal of the American Concrete Institute, 91 (4), pp. 465-474; Belarbi, A., Hsu, T.T.C., Constitutive laws of softened concrete in biaxial tension- compression (1995) Structural Journal of the American Concrete Institute, 92 (5), pp. 562-573; Bentz, E.C., (2000) Sectional analysis of reinforced concrete members, , PhD. thesis, University of Toronto, Toronto; Brunesi, E., Nascimbene, R., Extreme response of reinforced concrete buildings through fiber force-based finite element analysis (2014) Engineering Structures, 69, pp. 206-215; Cassese, P., Ricci, P., Verderame, G.M., Experimental study on the seismic performance of existing reinforced concrete bridge piers with hollow rectangular section (2017) Engineering Structures, 144, pp. 88-106; Ceresa, P., Petrini, L., Pinho, R., Flexure-shear fiber beam-column elements for modeling frame structures under seismic loading – state of the art (2007) Journal of Earthquake Engineering, 11 (1), pp. 46-88; Ceresa, P., Petrini, L., Pinho, R., Sousa, R., A fibre flexure–shear model for seismic analysis of RC‐framed structures (2009) Earthquake Engineering and Structural Dynamics, 38 (5), pp. 565-586; Chang, G.A., Mander, J.B., (1994) Seismic Energy Based Fatigue Damage Analysis of Bridge Columns: Part I-Evaluation of Seismic Capacity, , National Center for Earthquake Engineering Research, Buffalo, New York, NY; Choi, E., Jeon, J.S., Lee, J.H., Park, S.H., Ha, S., Assessment of probabilistic seismic performance of RC columns jacketed by FRP winding wires using analytical models (2018) Engineering Structures, 171, pp. 629-646; Collins, M.P., Torque–twist characteristics of reinforced concrete beams (1973) Inelasticity and Non-Linearity in Structural Concrete, Study No. 8, pp. 211-232. , University of Waterloo Press, Waterloo, Ontario; Collins, M.P., Towards a rational theory for RC members in shear (1978) Journal of the Structural Division, 104 (4), pp. 649-666; Cook, R.D., Malkus, D.S., Plesha, M.E., Witt, R.J., (2002) Concepts and Applications of Finite Element Analysis, , 4th Ed., John Wiley and Sons publishers, NJ; Feng, D.C., Wu, G., Sun, Z.Y., Xu, J.G., A flexure-shear timoshenko fiber beam element based on softened damage-plasticity model (2017) Engineering Structures, 140, pp. 483-497; Ferreira, D., Bairán, J., Marí, A., Faria, R., Nonlinear analysis of RC beams using a hybrid shear-flexural fibre beam model (2014) Engineering Computations, 31 (7), pp. 1444-1483; Guedes, J., Pegon, P., Pinto, A.V., A fibre/timoshenko beam element in CASTEM 2000 (1994) Special Publication Nr.

The failure modes, hysteretic load-displacement loops, dissipated energy, and residual displacement were observed and analyzed. In addition, the seismic performance of proposed construction method with and without energy dissipation rebar, different level of posttensioning were studied. The test results were used to verify the Finite Element Model (FEM) developed in this study. Tested specimens were modeled using the ABAQUS platform under quasi-static loading. The analytical model considered interaction between precast elements, unbonded strands, and surrounding concrete and bond slip between column main reinforcement and concrete. Developed FEM for monolithic bridge pier showed comparable results with the experimental tests. FEM was able to predict the hysteretic behavior of modeled bridge piers with high degree of accuracy. In addition, FEM confirmed the experimental observations and showed that precast self-centering hammer head bridge piers system is capable of withstanding any large lateral displacements before achieving the peak lateral strength. Sensitivity analyses was conducted to investigate the effect of mesh size and bond-slip interaction. Finally a parametric study was conducted to study the effect of construction method, energy dissipation rebar ratio and socket depth on the hysteretic response of the modeled bridge piers. This study reveals that FE analysis using the proposed model is validated to be used in determining the appropriate range of applied posttensioning force; energy dissipation rebar ratio and recess depth. © 2020 The Author(s).

The elastomeric material of bearing pads is a synthetic rubber reinforced with carbon black particles and subjected to a process of vulcanization, also represented by hyperelastic material models based on strain energy density functions. The objective of the present paper is to use the finite element analysis software Abaqus® to select the most appropriate hyperelastic model, as well as its constants, applying them to a bearing pad installed in an existing viaduct, evaluating its behavior and the displacements resulting from the application of usual loads. A data fitting procedure is performed through the finite elements analysis software to obtain the Neo-Hooke, Arruda-Boyce and Yeoh model constants. The proposed methodology presents results that are coherent when compared to technical specification limits for available bearing pads products. © 2020.

This paper presents a half-bridge module integrating two GaN HEMTs with their gate drive stages and the DC-link capacitance on a multilayer AlN-substrate. The small layer distance of 10 µm achieved on the GaN half-bridge module allows for minimization of layout-related parasitic inductances. The parasitic circuit elements are evaluated and compared to conventional 4-layer PCB design using 3D-FEM field simulation and measurements. Due to a lateral commutation loop design, the GaN half-bridge module achieves notably lower parasitic capacitances but also a smaller commutation loop inductance. The thermal characterization of the fabricated half-bridge module validates the high cooling capability introduced by the AlN-substrate. The switching characteristics of the proposed GaN half-bridge module are studied in hard-switched mode. © VDE VERLAG GMBH · Berlin · Offenbach",,"Aluminum nitride; Capacitance; Cooling systems; Electronic cooling; Gallium nitride; High electron mobility transistors; III-V semiconductors; Inductance; Multilayers; Power HEMT; Printed circuit boards; Substrates; DC-link capacitance; High-efficiency operations; Parasitic capacitance; Parasitic circuit elements; Parasitic inductances; Power electronic systems; Switching characteristics; Thermal characterization; Wide band gap semiconductors",,,,,,,,,,,,,,,,"Teulings, W., Schanen, J., Roudet, J., MOSFET switching behaviour under influence of PCB stray inductance (1996) Conference Record of the 1996 IEEE Industry Applications Conference Thirty-First IAS Annual Meeting, , und; Chen, J.

New requirements are in force from 1 January 2015, when Road and Bridge Research Institute informed that each pole liable to a direct vehicle impact has to meet Standard PN-EN 12767. The article presents the design of a novel, safe lighting pole. The novelty lies in the pole simplicity, which results in the manufacturing technology the cost of which is comparable to that of the conventional pole. Compared to the conventional poles of thickness 3 mm and greater, this one is made of thin-walled steel sheet of increased strength parameters and specially designed sleeve that is fixed to the base plate. The crash tests carried out on the track for the impact experiments proved that the requirements of the standards in the driver highest safety class and in the high vehicle kinetic energy absorption were satisfied both for the speed impact 35 km/h and 100 km/h. The numerical model for simulations of the vehicle behaviour during and after the impact was implemented in software Ansys LS-Dyna. The simplifications of some elements were of negligible influence on the analysed phenomena. The comparative parameters were ASI, THIV and exit velocity of the vehicle. The numerical results were close to the empirical ones, therefore they confirmed that finite element analysis can be successfully applied at the stage of elaborating of the initial concepts of the road lightning poles. It follows that the number of expensive crash tests can be reduced. © 2020, Poznan University of Technology.

To investigate the seismic performance of skew bridges considering the sliding behavior of laminated-rubber bearings, the Duxiufeng Bridge located in Sichuan, China, was used as a prototype bridge. This bridge is a skew bridge that suffered seismic damage during the 2008 Wenchuan earthquake. The possible seismic response of this skew bridge under the Wenchuan earthquake was simulated, and the postearthquake repair methods were analyzed considering the effects of bearing types and cable restrainers. Parametric studies, using the finite element method, were also performed to investigate the effects of the skew angle and friction coefficient of the bearings on the seismic response of the skew bridge. The results indicate that pin-free bearings could effectively control the seismic displacement of the bridge, and the cable restrainers with an appropriate stiffness could significantly reduce the longitudinal residual displacements. The effect of skew angles is less significant on skew bridges with laminated-rubber bearings than on rigid-frame skew bridges because of the sliding between the girders and bearings. The residual displacements of the bearings were more sensitive to the variation in the friction coefficient between the laminated-rubber bearings and the girders compared to the maximum seismic displacements. © 2020 Xueshan Liu et al.",,,,,,,,,,,,,,,,,,"Seible, F., Priestley, M.J.N., Lessons learned from bridge performance during Northridge earthquake (1999) Special Publication, 187, pp. 29-56; Hashimoto, S., Fujino, Y., Abe, M., Damage analysis of Hanshin Expressway viaducts during 1995 Kobe earthquake.

The results show that the temperature distribution in the concrete box girder (CBG) is strongly influenced by its size, and the temperature distribution in the girder changes along the longitudinal direction of the bridge. To clarify the temperature distribution in the long-span PCBG bridge, a two-dimensional (2D) temperature prediction model, validated by the measured data, was proposed, and the effect of the girder size on the temperature distribution of the CBG was studied using the model. Based on the results of the studies, simplified vertical and transverse temperature gradient models that could consider changes along the longitudinal direction of the bridge were proposed and validated by using the measured data and three-dimensional (3D) mechanical finite element model (FEM) of the bridge. Then, the deformations and stresses derived from the proposed temperature gradient models and the models according to different codes were studied and compared. Finally, conclusions and recommendations for future bridge design are provided. © 2020 B.

To reduce the number of variables to be optimized, a discrete phases approach for structural optimization is developed in this study. The approach couples the finite element method with the genetic algorithm optimization approach. The design variables are divided into two categories: (i) main variables: Number of stay cables, I-girder inertia, concrete slab thickness, and tower dimensions; and (ii) secondary variables: I-girder dimensions, stay-cable areas, and pre-tensioning forces. Two design objectives are tested: (i) lightest deck mass; and (ii) lowest material cost. Three load cases are considered: (i) dead and truck plus lane live loads; (ii) dead and lane live loads; and (iii) dead load. The results show the importance of considering the truck loads in structural optimization and the efficacy of the phases approach for different objectives. © 2020, Canadian Science Publishing.

A three-dimensional finite element analysis of a multispan continuous concrete girder bridge with FPB was established using the nonlinear time-history method to verify the accuracy of analytical modelling. The influence of the friction coefficient and isolation period of the FPB on the energy response of isolated bridge was then investigated under multihazard source excitations (e.g., El Centro and Taft waves) with different dominant periods and durations. The variations of structural response energy, sliding displacement, energy dissipation ratio, and acceleration of the isolated bridges are plotted. The results of analytical modelling and finite element simulation show good agreement. In addition, there exist particular values of the friction coefficient and isolation period of FPB, for which the structural response energy of the isolated bridges attains the minimum value. The optimal parameters of FPB are greatly influenced by seismic waves, and the friction coefficient of FPB should be increased with the increase of seismic fortification intensity. In addition, the energy dissipation capacity of FPB used in isolated bridge is excellent.

Corrugated steel plates are widely utilized as web members of bridge girders for pre-stressed concrete bridges. In the lifetime of such a structure, performance and stability will degrade due to the effects of many factors. This process is usually accompanied by the development of corrosion and loss of thickness in the affected region. This paper aimed to study the vibration characteristics of corrugated web and flanges of bridge girder undergoing corrosion and loss of section problem. The finite element analysis utilizing ABAQUS CAE software has been adapted to model and solve this problem. First, the baseline model of undamaged and healthy corrugated plate was modelled to determine its natural frequency and mode shape. The baseline model results were further used to compare with the damage model. The size of the damage area was fixed, while the position, orientation, and depth of loss of thickness varied for different damage cases. A significant reduction in natural frequency can be observed in the presence of damage to corrugated web bridge girders. © Universiti Tun Hussein Onn Malaysia Publisher's Office.","Corrugated plate; Finite element analysis; Modal analysis; Natural frequency",,,,,,"Ministry of Higher Education, Malaysia, MOHE; Universiti Teknologi MARA, UiTM: RACER/1/2019/TK01/UITM/2","The authors wish to acknowledge the Ministry of Higher Education Malaysia and Universiti Teknologi MARA, Shah Alam for supporting this publication process via research grant RACER/1/2019/TK01/UITM/2.",,,,,,,,,,"Metwally, A.E., Loov, R.E., Corrugated steel webs for prestressed concrete girders, materials and structures (2003) Materiaux et Constructions, 36, pp. 127-134; Ikeda, S., Sakurada, M., Development of hybrid prestressed concrete bridges with corrugated steel web construction (2005) Proceedings of the 30th Conference on Our World in Concrete and Structures, , Singapore; Mutsuyoshi, H., Hai, N., Perera, S., Development of modern prestressed concrete bridges in Japan (2013) Jupiter Civil Saitama, 38, pp. 18-25; Cheyrezy, M., Combault, J., Composite bridges with corrugated steel webs-achievements and prospects (1990) IABSE Reports, 60, pp. 479-484; Su, Z., Ye, L., (2009) Identification of Damage Using Lamb Wave, , Heidelberg: Springer; Lifshitz, J.M., Rotem, A., Determination of reinforcement unbonding of composites by a vibration technique (1969) Journal Composite Materials, 3 (3), pp. 412-423; Kudus, S.A., Suzuki, Y., Matsumura, M., Sugiura, K., Vibration-response due to thickness loss on steel plate excited by resonance frequency (2018) IOP Conference Series: Earth and Environmental Science, 140 (1), p. 012123; Kudus, S.A., Suzuki, Y., Matsumura, M., Sugiura, K., Damage assessment based on modal analysis of pipe structure (2018) Jurnal Teknologi, 80 (5), pp. 10-20; Hassanein, M.F., Kharoob, O.F., Behavior of bridge girders with corrugated webs: (I) real boundary condition at the juncture of the web and flanges (2013) Journal of Engineering Structures, 57, pp. 554-564; Kudus, S.A., Suzuki, Y., Matsumura, M., Sugiura, K., Damage assessment based on sensitivity of modal parameter in plated structure (2018) Malaysian Construction Research Journal, 24 (1), pp. 65-82","Kudus, S.A.; Faculty of Civil Engineering, Malaysia; email: sakhiah@uitm.edu.my",,,"Penerbit UTHM",,,,,2229838X,,,,"English","Int.

The explicit dynamic FE software, LS-DYNA, was employed to conduct the simulation of over-height truck collision with bridge under 17 cases, which various vehicle impact speeds, vehicle impact masses, over heights of vehicle, thicknesses of carriage, positions of collision and concrete strengths were included in the analysis. The damage of impacted girder under different vehicle velocities was analyzed and the vertical bearing capacity of damaged girder was calculated to investigate its severity of damage. The results indicated that the vertical bearing capacity declined slightly in all cases if the prestressed bars work properly after collision. However, the vertical bearing capacity decreased by 56% once the prestressed bars all failed on the impact side after collision. As the same time, the characteristics of simplified collision force were analyzed and the sensitivity of vital indicators to all load cases were investigated. The results showed that vehicle velocity and carriage thickness exert a non-negligible effect on peak force, and the average force and duration time are mainly influenced by vehicle velocity, vehicle mass, collision height and carriage thickness. © 2020 IEEE.","Collision force; Numerical simulation; Over-height truck; Prestressed concrete box bridge","Bearing capacity; Big data; Computer software; Prestressed concrete; Smart city; Trucks; Velocity control; Collision forces; Concrete strength; Duration time; Explicit dynamics; Simply supported bridge; Vehicle impact; Vehicle velocity; Vertical bearing capacity; Finite element method",,,,,,,,,,,,,,,,"Yi, J.Y., Zhou, R.F., Huang, Q., The causes and risk analysis of domestic bridge collapse accidents in recent 15 years[J] (2015) Journal of Highway and Transportation Research and Development, 5, pp. 61-64; Lu, X.Z., Zhang, Y.S., Ye, L.P., Failure modes and load calculation of collision between over-height truck and bridge superstructure[J] (2009) China Journal of Highway and Transport, 22 (5), pp. 60-67; Lu, X.Z., Zhang, Y.S., He, S.T., Collision between over-height truck and bridge superstructures: Damage mechanism and impact loads[J] (2009) Engineering Mechanics, 26 (2), pp. 115-125; Zhang, Y.S., Lu, X.Z., Ning, J., Simulation for the impact between over-height truck and steel-concrete composite bridge[C] (2007) Proceedings of the 9th International Conference on Steel Space & Composite Structures; Tian, L., Feng, Z.N., Dynamic response of collision between over-height truck and prestressed box girder bridge superstructure] (2016) Journal of Southwest Jiaotong University, 4, pp. 632-638; Peng, W.B., Dai, F., Analysis of a collapsed pedestrian bridge impacted by over-height vehicle[EB/OL], , https://mp.weixin.qq.com/s/uHG8q4iptAJW29iaWs22sQ; (2015) LS-DYNA keyword user's manual R8. 0[M|, , Livermore Software Technology Corporation.

To account for the increase in structural response due to the dynamic application of loads, amplification factors are prescribed by the codes. These amplification factors have been derived from extensive large-scale laboratory testing on model concrete and steel bridges, carried out in the 1970s. Analytical solutions to the dynamic response of an undamped simply supported beam to moving loads demonstrate general agreement with these tests, and form the basis of the formulae used to determine dynamic amplification factors. This paper investigates the suitability of applying the dynamic amplification formulae to masonry arches. In particular, the critical role of determinant length and the chosen vibration mode and frequency is considered. To achieve this, the dynamic response of a damped two-hinged circular arch due to a moving point load is evaluated using Galerkin’s method. Solutions are compared to classical solutions and finite element analysis results for an instrumented single span arch, to highlight the limitations of codified formulae. © Springer Nature Switzerland AG 2020.","Analytical dynamics; Dynamic amplification; Galerkin’s method; Masonry arch bridges; Railways",,,,,,,,,,,,,,,,,"(2006) NR_GN_CIV_025, Structural Assessment of Underbridges, , Network Rail; Timoshenko, S.P., (1940) Strength of Materials, , Part I, II, 2nd edn.

To validate the approach, fatigue analysis of the panel RC slab is conducted using a finite element method (FEM) based numerical model with the bridging stress degradation concept. Both the proposed approximate boundary conditions, and those that have been typically employed in past studies, are used. The numerical results demonstrate that the panel RC slab with approximate boundary conditions experiences the same bending moment distribution and deformations around the loading locations as the load moves along the slab axis, similar to those of a real bridge RC slab. Moreover, the approximate boundary conditions reproduce the extensive grid crack pattern in the panel RC slab, which is similar to that generally observed in a real bridge RC slab. The results of this study establish that panel RC slab with approximate boundary conditions behaves in a similar manner to a real bridge RC slab, which results in a more realistic fatigue life estimation.

Due to economic and other constraints, replacement of all these deteriorating structures is not feasible. Therefore, their effective rehabilitation is paramount. One of the effective ways to rehabilitate steel structures is with the use of fibre-reinforced polymers (FRP). This paper explores the effectiveness of rehabilitating corroded webs in steel I-shaped beams with unidirectional basalt fibre reinforcement polymer (BFRP) fabric. The structural deficiency was induced to the web of the beam by cutting a circular shaped area out of the web. The section loss was repaired with BFRP fabric using the wet lay-up technique. Overall, seven beams were tested utilizing a 4-point test setup, including a control (undamaged) beam, control corrosion (damaged) beam, and five rehabilitated specimens. Two patterns of rehabilitation were performed by attaching BFRP fabrics in horizontal and vertical orientations. The study concluded that the BFRP fabrics were effective in restoring elastic stiffness, yield load, and ultimate load capacity of rehabilitated beams to that of an undamaged steel beam. The tests also showed that there was a direct correlation between the improvement of structural behaviour and thickness and orientation of the BFRP fabric. Nonlinear finite element analysis was successfully used in this study to determine the optimum pattern of rehabilitation with BFRP fabrics. © 2020 American Society of Civil Engineers.",,"Basalt; Deterioration; Fiber reinforced plastics; Polymers; Reinforcement; Steel fibers; Steel structures; Basalt fibre reinforcements; Deteriorating structures; Elastic stiffness; Fibre reinforced polymers; Non-linear finite-element analysis; Steel I-shaped beams; Structural behaviour; Ultimate load capacity; Steel corrosion",,,,,"Ontario Centres of Excellence, OCE","This study was financially supported by MEDA Ltd. located in Windsor, ON, Canada and Ontario Centres of Excellence located in Toronto, ON, Canada.

The beam4 element is used to simulate the main beam to establish the ""spine beam"" model of the Taizhou Yangtze River Bridge. The calculated low-order vibration mode frequency of the FEM is in good agreement with the completion test results. The model can simulate the overall dynamic response of the bridge. Based on the vehicle load survey, the Monte Carlo method is applied to simulate the traffic load flow. Then the overall dynamic response analysis of FEM is carried out. Taking the bending moment of the main beam as the control index, the fatigue sensitive section in the steel box girder of FEM is analyzed. Based on the strain time history data of steel box girder recorded by the structural health monitoring system (SHM), the true stress response of steel box girder under vehicle load is extracted. Taking the cumulative fatigue damage increment as the evaluation index, the fatigue performance evaluation of the steel box girders is conducted based on the collected health monitoring data. The fatigue effect of the beam section near the steel tower, especially the first section of the middle tower, is the key section of the fatigue analysis by health morning system, which is consistent with the calculation results of FEM. © 2020 Tech Science Press.

This difficulty results in problems, such as stress concentration and screw corrosion and loosening, and weakens structural bearing capacity, stiffness, and integrity. In this study, an experimental model of glued timber T-section beams formed by gluing between bridge decks and rectangular beams and a calculation method for T-beam shear stress were proposed to improve the bearing capacity, stiffness, and integrity of the structure for ensuring that the bridge deck and the rectangular beam jointly bear stress. Three sets of beams, namely orthogonal T-beams, parallel T-beams, and rectangular beams were made using Larix gmelinii larch boards and structural glue to perform static bending bearing capacity test for examining the strain, deflection, and ultimate bearing capacity of the members and observe the destruction pattern. During the test, the bending shear strength was calculated following the principle of equivalent stiffness and the shear strength formula proposed by Rammer. Furthermore, a finite element model of glulam beams based on elastoplastic theory was established using structural analysis software. The displacement, strain, and failure mechanism of the members under the test loads were simulated and analysed using the model to verify the test results. Results demonstrate that, when the three types of beams are bent, they are sheared along the grain near the central axis of the section. The bonding surface between the wing plate and rib of the T-beam is undamaged, and the bonding is reliable with strong structural integrity. Compared with those of rectangular beams, the bearing capacity (limit load), bending stiffness, and ductility coefficient of the parallel T-beams are increased by 71%, 189%, and 23%, respectively. Compared with those of rectangular beams, the bearing capacity, bending stiffness, and ductility coefficient of the orthogonal T-beams are increased by 33%, 28%, and 25%, respectively. Compared with those of rectangular beams, the bearing capacity, bending stiffness, and ductility coefficient of the glulam T-beams are greatly improved. By considering the principle of equivalent stiffness and using the Rammer formula, the shear strength test values of orthogonal T-beams and rectangular beams of glulam deviate from the calculated values by 8.0% and-5.6%, respectively, which indicates good agreement. However, the shear strength test value of the parallel T-beams deviates from the calculated value by 19.2%, which indicates slightly lower calculation accuracy. The finite element analysis is consistent with the results of the experiment. This study provides certain references for the engineering design of glulam T-beams. © 2020 School of Science, IHU.","Finite element; Flexural bearing capacity; Glulam T-beam; Larch wood; Longitudinal shear","Bearing capacity; Bearings (machine parts); Bending strength; Bridge decks; Corrosion; Ductility; Elastoplasticity; Finite element method; Glues; Gluing; Plates (structural components); Shear stress; Stiffness; Wooden beams and girders; Ductility coefficient; Experimental modeling; Flexural bearing capacity; Larch woods; Longitudinal shear; Structural analysis softwares; T beams; Ultimate bearing capacity; Failure (mechanical)",,,,,"2014DFA53120","This work was supported by the International S&T Cooperation Program of China (Grant No.2014DFA53120) and the Special Research Program for Public-welfare Forestry of China (Grant No.201304504-3).",,,,,,,,,,"Liu, W.Q., Yang, H.F., Research Progress of Modern Wood Structures (2019) Journal of Building Structures, 40 (2), pp. 16-43; Wang, J.J., Yang, T., Zhang, X.S., Static and Stability Analysis of Glulam Continuous Beam Corridor Bridge (2018) Journal of Central South University of Forestry and Technology, 38 (7), pp. 103-109 and 122; Gao, J., Dong, W.W., Huang, S.Y., Zhong, Y., Ren, H.Q., Research progress on influencing factors of nail joint performance in wooden structures (2016) Forest Products Industry, 43 (4), pp. 7-11; Andrew, J.B., Corrosion of nails in CCA-and ACA-treated wood in two environments (1992) Forest Products Journal, 42 (9), pp. 39-41; Hiroshi, Y., Toshifumi, F., Shear strengths of wood measured by various short beam shear test methods (2003) Wood Science and Technology, 37 (3), pp. 189-197; Roberto, T., Maria, A.P., Maurizio, P., Ductile design of glued-laminated timber beams (2009) Practice Periodical on Structural Design and Construction, 14 (3), pp. 113-122; Rammer, D.R., Soltis, L.A., Experimental shear strength of Glulam-laminated beams (1994) Forest Products Laboratory, Research Paper: FPL-RP-527, pp. 1-38. , Madison WI, USA: USDA; Cao, L., Zhang, Z.F., Zeng, D., He, G.J., Study on fatigue properties of larch beams (2016) Journal of Building Structures, 37 (10), pp. 27-35; Zhou, J.L., Feng, X., Experimental study on mechanical properties of larch glued wood (2016) Journal of Central South University of Forestry and Technology, 36 (8), pp. 125-130; Klapalek, P., Melzerpva, L., Effect of distribution of Knots on the strength of the glued laminated timber beam (2015) Applied Mechanics and materials, 732, pp. 365-368; Danielsson, H., Serrano, E., Cross laminated timber at in-plane beam loading-Prediction of shear stresses in crossing areas (2018) Engineering Structures, 171, pp. 921-927; Sikora, K.S., McPolin, D.O., Harte, A.M., Effects of the thickness of cross-laminated timber (CLT) panels made from Irish Sitka spruce on mechanical performance in bending and shear (2016) Construction and Building Materials, 116, pp. 141-150; Lu, Y., Xie, W.B., Wang, Z., Shear Stress and Interlaminar Shear Strength Tests of Cross-laminated Timber Beams (2018) Bioresources, 13 (3), pp. 5343-5359; Gong, Y.C., Wu, G.F., Xu, J.H., Ren, H.Q., Study on flexural properties of Japanese larch orthogonal glulam (2018) Journal of Northwest A & F University (Natural Science Edition), 46 (11), pp. 1-6; Julio, S., Bruno, P.P., Nilson, T.M., Mechanical performance of glued-laminated timber beams symmetrically reinforced with steel bars (2016) Composite structures, 150, pp. 200-207; Yang, X.H., Xue, W., Guo, N., Bending resistance of steel plate reinforced glulam beams (2017) Journal of Jilin University (Engineering & Technology Edition), 47 (2), pp. 468-477; Zhang, J., Wang, W.C., Chou, R.G., Shen, H., Xu, Q.F., Gao, S., Experimental study on short-term bending performance of prestressed glulam beams in vivo (2019) Journal of Civil Engineering, 52 (5), pp. 23-34; Ewa, S., Maciej, S., Lukasz, P., A Numerical Analysis of the Resistance and Stiffness of the Timber and Concrete Composite Beam (2015) Civil And Environment Engineering Reports, 15 (4), pp. 139-150; Chen, Q., Lang, J.K., Wang, J.J., Flexural Properties of Bamboo-Log Composite Beam (2018) Journal of Engineering Science and Technology Review, 11 (3), pp. 104-112; McConnell, E., McPolin, D., Taylor, S., Post-tensioning of glulam timber with steel tendons (2014) Construction and Building Materials, 73, pp. 426-433; Yahyaei-Moayyed, M., Taheri, F., Experimental and computational investigations into creep response of AFRP reinforced timber beams (2011) Composite Structures, 93, pp. 616-628; Long, W.G., Yang, X.B., (2005) Wood Structure Design Manual (Third Edition), pp. 16-18. , Beijing: China Construction Industry Press, China","Wang, J.; School of Civil Engineering, China; email: wangjiejun2011@126.com",,,"Eastern Macedonia and Thrace Institute of Technology",,,,,17919320,,,,"English","J.

The proposed MHP has been designed for low power consumption and uniform temperature distribution throughout the active area of 240 µm × 240 µm. To validate our simulation, we compared the results with the experimental data, reported by Iwata et al. The power consumption of the heater is approximately corresponded to 13.5 mW for heating to 300°C (heat transfer coefficients calculated), we noticed a reduction of power consumption by more than 8 mW compared to our first simulation (standard heat transfer coefficient parameters) which proves the impact of heat transfer coefficients on power consumption. Also, overheating problem in the heater center is analyzed, several modifications on the MHP center design have been established to keep the best temperature homogeneity, results show that temperature gap between extremities and the center of the active area is reduced by less than 15 °C. © 2020, S.C.

Numerical analysis based on the finite element method (FEM) and theoretical analysis showed that the AASHTO formula gives relatively accurate stress values when the effect of duct holes is neglected. However, it was found that the formula can significantly overestimate the stresses in the actual prestressed concrete member with spaces occupied by ducts. Therefore, an improved equation was proposed for the existing AASHTO equation to consider the effect of the duct holes on the stress distribution. This resulted in relatively accurate prediction of the distribution and magnitude of the compressive stresses even with the presence of the duct holes. The proposed equation was also validated by comparing with the stresses measured in the test of a posttensioned full-scale specimen. This study is expected to contribute to the design of the anchorage zone in prestressed concrete structures by suggesting a more reasonable way to assess the appropriateness of anchorage devices. © 2020 Young-Ha Park et al.",,,,,,,,,,,,,,,,,,"Nilson, A.H., (1987) Design of Prestressed Concrete, , 2nd New York, NY, USA Wiley;

These parameters are used to obtain high-fidelity numerical models through FEM model updating by fine-tuning mass, stiffness and boundary conditions and matching the numerical and observed modal parameters. This study investigated sensitivity of modal parameters to changes in boundary conditions (soil-structure interaction effect) and pier column inelasticity (stiffness effect) through more than 450 non-linear dynamic time-history analysis of an ordinary multi-span bridge. The bridge system was founded on shallow foundations in five rock profiles and on pile foundations in five soil profiles and was subjected to 21 seismic ground motions of varying intensity (0.036 to 0.61g). Modal frequencies showed sensitivity to the SSI and pier column inelasticity effects for low and higher levels of seismic excitations respectively. Mode shapes, on the contrary, were insensitive to SSI as well as pier column inelasticity for all levels of seismic excitations. © 2020, Brazilian Association of Computational Mechanics.

In our work, NiTi/Si micro-bridge with a design of tunable resonance based sensor was successfully fabricated using Xe+ plasma focused ion beam (FIB). Before fabricating the microbridge, an influence of various Xe+ FIB currents on the transformational behavior of NiTi films was tested. In the other part of the present study, the effect of temperature on the vibrating NiTi/Si microbridge was examined in a broad range of frequencies. It is suggested that the NiTi film can work as a frequency tuning element in resonance based mass sensors. The shift of the first resonant frequencies of NiTi/Si bilayer micro-bridge with the length, width, thickness and the NiTi/Si thickness ratio being 200 μm, 40 μm, 5.8 μm and 0.29, respectively, is up to 7% with temperature ranging from 25 °C to 100 °C during heating up. The finite element analysis of the micro-bridge is done in order to calibrate the NiTi/Si micro-bridge resonator sensor. © 2019 IOP Publishing Ltd","AFM; MEMS; NiTi film; Resonant ultrasound spectroscopy; Sensor fabrication; Xe+ FIB","Binary alloys; Ion beams; MEMS; Natural frequencies; Resonators; Silicon; Effect of temperature; Frequency-tuning; NiTi films; Resonant frequency shift; Resonant Ultrasound Spectroscopy; Sensor fabrication; Thickness ratio; Tunable resonances; Bridges",,,,,"Grantová Agentura České Republiky, GA ČR: FUNBIO CZ.2.16/3.1.00/21568, GA17–05360, GA18–03834, LM2015088, LO1409","This work has been supported by the Czech Science Foundation, within project GA17–05360 S (acknowledged by DV and JN), GA18–03834 S (acknowledged by LK and LH) and FUNBIO CZ.2.16/3.1.00/21568, LO1409 and LM2015088.",,,,,,,,,,"Fu, Y.Q., Huang, W.M., Du, H.J., Huang, X., Tan, J.P., Gao, X.Y., Characterization of TiNi shape-memory alloy thin films for MEMS applications (2001) Surf.

It helps maintain the accessible area of the road when repairs occur. Collapse has occurred sometimes at frame when bending load exceeds the yield strength. In addition to increase the ability of the structure and avoid buckling added a link as damper. Parameters of the absorber are stiffness rate, and elongation of link. A simple square tube beam model supported by a link was created to investigate the bending behavior using finite element analysis. The analysis result showed that beam supported by a link able to reduce buckling moreover provides longer curvature than beam without a link. © 2020 by authors, all rights reserved.","Finite Element; Flexible Bridge",,,,,,,,,,,,,,,,,"Kecman, D., Bending Collapse of Rectangular and Square Section Tubes (1983) International Journal of Mechanical Science, 25 (9-10), pp. 623-636. , Volume, No, pp; Wierzbicki, T., Recke, L., Abramowicz, W., Gholami, T., Huang, J., Stress Profiles In Thin-Walled Prismatic Columns Subjected to Crush Loading-II Bending (1994) Computer and Structures, 51 (6), pp. 625-641. , Volume, No, pp; Shi, W., Li, X., Wang, F., C, Y., Bending Of Rectangular Plate With Rotationally Restrained Edges Under A Concentrated Force (2016) Applied Mathematics and Computational, Volume, 286, pp. 265-278. , pp; Wang, J., Afshan, S., Schillo, N., Theofanous, M., Feldmann, M., Gardner, L., Material properties and compressive local buckling response of high strength steel square and rectangular hollow sections (2017) Engineering Structures, 130, pp. 297-315. , Volume, pp; Kim, T.H., Reid, S.R., Bending Collapse of Thin-Walled Rectangular Section Columns (2001) Computer and Structures, 79, pp. 1897-1911. , Volume, pp; Abramowicz, W., Simplified Crushing Analysis of Thin-Walled Columns and Beams (1983) Engng Trans, Volume, 29, pp. 3-27. , pp; Goncalves, R., Gamotim, D., Buckling Behaviour of Thin-Walled Regular Polygonal Tubes Subjected to Bending or Torsion (2013) Thin-Walled Structures, 73, pp. 185-197. , Volume, pp; Chen, D.H., Masuda, K., Rectangular hollow section in bending: Part I-Cross Sectional Flattening Deformation (2016) Thin-Walled Structures, 106, pp. 495-507. , Vol., pp; Haruyama, S., Oktavianty, O., Darmawan, Z., Kyoutani, T., Kaminishi, K., Study on Energy Absorption Characteristic of Cab Frame with FEM (2016) International Journal of Mechanical, Aerospace, Industrial, Mechatronic and Manufacturing Engineering, 10 (3), pp. 570-576. , Vol., No:, pp; Johnson, A.F., Bending and Torsion of Anisotropic Beams (1973) International Journal Solids Structures, 9, pp. 527-551. , Volume, pp; An, X., Gao, Y., Fang, J., Sun, G., Li, Q., Crashworthiness Design for Foam-Filled Thin Walled Structures with Functionally Lateral Graded Thickness Sheets (2015) Thin-Walled Structures, 91, pp. 63-71. , Volume, pp; Ziao, Z., Fang, J., Sun, G., Li, Q., Crashworthiness Design for Functionally Graded Foam-filled Bumper Beam (2015) Advances in Engineering Software, 85, pp. 81-95. , Volume, pp; Guarracino, F., Walker, A., (1999) Energy Methods in Structural Mechanics: A Comprehensive Introduction to Matrix and Finite Element Methods of Analysis, p. 307. , London: Thomas Telford, pp","Oktavianty, O.; Department of Industrial Engineering, Indonesia",,,"Horizon Research Publishing",,,,,23321091,,,,"English","Civil Engi.

During their use in operation, they are exposed to different environmental influences. These include, in particular, climatic factors such as air oxygen, high temperatures, light (UV radiation) and the influence of media (e.g. oils, fuels). A very important result of these factors is the chemical ageing of elastomers. In this case, the elastomer degenerates and changes its chemical structure in the aged regions, which leads to an irreversible change in the material properties in connection with the reduction in its usability. In this paper, chemical ageing of nitrile butadiene rubber (NBR) is investigated. Especially in case of thermo-oxidative ageing at elevated operating temperatures, the ageing processes run inhomogeneously. These effects are known as diffusion-limited oxidation (DLO) and are associated with the diffusion–reaction behaviour of atmospheric oxygen with the elastomer network. For these reasons, NBR samples are artificially aged in air and subjected to different experimental methods, which are presented and discussed. Additional results from inhomogeneous mechanical tests and permeation tests indicate the causes of the DLO-effect, show the influence of chemical ageing and are subsequently used for parameter identification in relation to the diffusion–reaction equation. A continuum-mechanical modelling approach is also presented here, which describes the finite hyperelasticity, diffusion–reaction processes as well as chemical degradation and reformation of the elastomer network. This multifield problem leads to a system of partial and ordinary differential equations and constitutive equations and is solved within the finite element method. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.","Chemical ageing; DLO; Hyperelasticity; NBR","Constitutive equations; Continuum mechanics; Cyanides; Degradation; Diffusion; Elasticity; Ordinary differential equations; Oxygen; Parameter estimation; Plastics; Polymer blends; Chemical ageing; Diffusion limited oxidation; Environmental influences; Experimental investigations; Hyper-elasticity; Nitrile butadiene rubber; Operating temperature; Thermo-oxidative ageing; Rubber",,,,,"Deutsche Forschungsgemeinschaft, DFG: JO 818/3-1","The financial support of the project by the Deutsche Forschungsgemeinschaft (DFG) under the Grant Number JO 818/3-1 is gratefully acknowledged.

In this paper, a strain-displacement conversion method for reconstructing the deformed shape of rectangular plate with typical boundary conditions is presented. This method overcomes the above shortcomings for small deflection nonlinear vibration in linear elastic range. Strains measuring points are uniformly and regularly distributed in the middle area of the plate. Unmeasurable boundary strains will be estimated using the new derived formula according to quadratic interpolation of strains and boundary conditions. The principle of the proposed method is to bridge the orthogonal deflection curves by translating and rotating them. In this way, framework of displacement field can be formed. First, curvature integral method is employed to shape the orthogonal deflection curves of deformed plate. Then, the rotating angles and translating displacements are deduced according to boundary conditions. For some special boundary plates, it even needs to solve nonlinear optimization problem to get the rotating angles. The displacement field reconstructed by the proposed method shows great agreement with the finite element analyses results, which verifies the effectiveness of the methodology. © 2019 John Wiley & Sons, Ltd.","boundary strains; bridging; curvature integration; deflection curves; displacement field reconstruction; thin rectangular plate","Boundary conditions; Deflection (structures); Nonlinear programming; Strain; Wave effects; bridging; Curvature integration; Deflection curves; Displacement field; Thin rectangular plate; Vibrations (mechanical)",,,,,"National Natural Science Foundation of China, NSFC: 11502050, 11672072","This work was supported by the National Natural Science Foundation of China (Grant 11672072, 11502050).

The test design for concrete samples is based on finite element analysis for a prestressing process. For end anchorage specimens, the relative location of the reinforcement centroid with respect to the bursting force center was investigated. The test results indicate that the specimen with the coincident reinforcement centroid shows the best performance in resisting the tension load. The presence of spiral reinforcement in the region below the bearing plate results in a redistribution of internal stresses in the anchorage zone. Therefore, Mörsch’s model should be refined by moving the STM configuration down by a distance of a quarter of the anchor size. For the interior anchorage zone, the test results confirm that the modified International Federation for Prestressing model offers a safe but economical STM scheme for the interior anchorage zone.

In addition, the analytical methods based on simplified geometries and models are not sufficiently detailed for the study of complex structures and phenomena. The virtual prototyping, and its different capabilities, can be a powerful method for instrument makers and museum curators as a decision support tool. Nevertheless, the accuracy of the model is an important matter to assess good predictions. In the case of antique and unique instruments, it is sometimes hard to obtain exhaustive geometrical properties. Similarly, it is also difficult to evaluate the material properties of full instruments, and this uncertainty may have a strong impact on the output features of the numerical models. In this study, a numerical model of cello is developed using finite element method. It is used to evaluate the impact of a modification of a geometrical property on dynamical features. It is shown that the lack of knowledge on the arching height of the top and back plates of a cello has a strong impact on the computed dynamical properties of the cello. Secondly, the model is considered with and without repair cleats and defects like galleries excavated by wood-boring insects. It is observed that the bridge admittance exhibits discrepancies above 220 Hz which is in the low frequencies domain of the model and quantify the impact of repairs. This model capability is a starting point for further simulations accounting for material and geometrical uncertainties and to assess the confidence level of a model for restoration issues. © Society for Experimental Mechanics, Inc. 2020.","Cultural heritage conservation; Dynamical modelling; Finite element model; Musical acoustics; Virtual prototyping","Decision support systems; Geometry; Historic preservation; Musical instruments; Numerical methods; Numerical models; Restoration; Structural dynamics; Uncertainty analysis; Virtual prototyping; Cultural heritage conservation; Decision support tools; Decision supports; Dynamical features; Dynamical properties; Geometrical property; Geometrical uncertainty; Musical acoustics; Finite element method",,,,,,,,,,,,,,,,"Knott, G.A., (1987) A Modal Analysis of the Violin Using MSC/NASTRAN and PATRAN, , Naval Postgraduate School, Monterey, CA; Pyrkosz, M.A., Reverse engineering the structural and acoustic behavior of a Stradivari violin (2013) Dissertation, Michigan Technological University; Gough, C., Vibrational Modes of the Violin Family (2013) SMAC 13 Stockholm, pp. 66-74; Viala, R., Placet, V., Cogan, S., Foltête, E., Model-based effects screening of stringed instruments (2016) Conference Proceedings of the Society for Experimental Mechanics Series, 3, pp. 151-157. , vol., pp; Viala, R., Towards a model-based decision support tool for stringed musical instrument making (2018) Dissertation, Université Bourgogne Franche-comté; van den Bulcke, J., van Loo, D., Dierick, M., Masschaele, B., van Hoorebeke, L., van Acker, J., Nondestructive research on wooden musical instruments: From macro-to microscale imaging with lab-based X-ray CT systems (2015) J.

Despite the low torsional stiffness that this particular deck configuration exhibits, several structures of this type do exist in both conventional and high-speed railway lines in Spain. Even though railway administrators recommend the construction of transverse or end beams bracing the longitudinal girders at the supports in girder bridges, in several occasions these elements are not built in order to accelerate the construction process. The aim of this study is to evaluate the beneficial effect of installing these transverse beams on the vertical dynamic response of the aforementioned structures and to determine what particular bridges are most affected by the presence of these elements. To this end, a representative ensemble of girder bridges covering a range of span lengths L between 10 m and 25 m has been predimensioned and their dynamic behaviour has been predicted by a finite element model that adopts common assumptions in engineering practice. Conclusions show that installing these elements is particularly relevant in the case of short (10–12.5 m) oblique bridges with a low number of longitudinal girders for a particular deck bending stiffness, leading to an important increase of the first torsion and first transverse bending natural frequencies and to a reduction of the structural response. Finally, experimental measurements on a real bridge belonging to the Madrid-Sevilla high-speed line are included in the final section to illustrate the theoretical derivations. © 2019 Elsevier Ltd","Bracing beams; Bridge dynamics; Finite elements; Railway bridges; Vertical acceleration","Concrete beams and girders; Dynamic response; Finite element method; Prestressed concrete; Railroad transportation; Railroads; Stiffness; Vibration analysis; Bracing beams; Bridge dynamics; Construction process; Engineering practices; High speed railway lines; Railway bridges; Theoretical derivations; Vertical accelerations; Bridges; bending; bridge; civil engineering; concrete structure; construction method; dynamic analysis; dynamic response; finite element method; railway; stiffness; structural analysis; structural component; structural response; vibration; Spain",,,,,"BIA2016-75042-C2; Universitat Jaume I, UJI: UJI-A2018-06","The authors would like to acknowledge the financial support provided by (i) the Spanish Ministry of Economy and Competitiveness under the research project [ BIA2016-75042-C2 ], (ii) the Andalusian Scientific Computing Centre (CICA) and (iii) Universitat Jaume I under the research project [ UJI-A2018-06 ].",,,,,,,,,,"Ponts Rails pour vitesses > 200km/h.

Performance of the machine depends on direct and quadrature axis inductances. The ratio of these inductances, saliency ratio, affect the torque density and power factor. Therefore, evolution of the rotor structure is presented to achieve high saliency ratio. So, to improve machine performance, ferrite magnets are introduced in the rotor such that polarity is along the maximum reluctance path of the rotor. For further increment of the saliency ratio, diamagnetic material is placed between the bridges to oppose quadrature axis flux and to reduce leakage flux. For validation, SynRM models, with and without ferrite magnets and diamagnetic material, are defined on FEA based ANSYS Maxwell platform to observe magnetic flux distribution. Also, saliency ratio for all the three are compared. Finally, comparisons of developed torque is presented for further verification. © 2019 IEEE.",,"Ferrite; Ferrite devices; Inductance; Magnetic polarity; Magnets; Power electronics; Reluctance motors; Ferrite magnet; Machine performance; Magnetic flux distribution; Quadrature axis; Rotor structures; Synchronous reluctance machine; Torque density; Vehicle applications; Rotors (windings)",,,,,,,,,,,,,,,,"Srinivas, B., Sashidhar, S., Fernandes, B.G., Multi-barrier twopole line-start synchronous reluctance motor with high saliency for a bore-well submersible pump (2018) 2018 IEEE International Conference on Industrial Technology (ICIT).IEEE; Lipo, Thomas, A., Synchronous reluctance machines-A viable alternative for ac drives (1991) Electric Machines and Power Systems, 19 (6), pp. 659-671; Musuroi, S., Low-cost ferrite permanent magnet assisted synchronous reluctance rotor an alternative solution for rare earth permanent magnet synchronous motors (2013) IECON 2013-39th Annual Conference of the IEEE Industrial Electronics Society.IEEE; Hui, H., Research of parameters and antidemagnetization of rare-earth-less permanent magnet-Assisted synchronous reluctance motor (2015) IEEE Transactions on Magnetics, 51 (11), pp. 1-4; Ramu, K., (2001) Switched Reluctance Motor Drives: Modeling, Simulation, Analysis, Design, and Applications, , CRC press; Nicola, B., Electric vehicle traction based on synchronous reluctance motors (2016) IEEE Transactions on Industry Applications, 52 (6), pp. 4762-4769; Payza, O., Demir, Y., Aydin, M., Investigation of Losses for a Concentrated Winding HighSpeed Permanent Magnet-Assisted Synchronous Reluctance Motor for Washing Machine Application (2018) IEEE Transactions on Magnetics, 54 (11), pp. 1-5; Kerdsup, B., Takorabet, N., Nahidmobarakeh, B., Design of Permanent Magnet-Assisted Synchronous Reluctance Motors with Maximum EfficiencyPower Factor and Torque per Cost (2018) 2018 XIII International Conference on Electrical Machines (ICEM).IEEE; Liu Huai, C., Design of permanent magnet-Assisted synchronous reluctance motor for maximized backEMF and torque ripple reduction (2017) IEEE Transactions on Magnetics, 53 (6), pp. 1-4; Srinivas, B., Sashidhar, S., Fernandes, B.G., Design and Optimization of a TwoPole LineStart Ferrite Assisted Synchronous Reluctance Motor (2018) 2018 XIII International Conference on Electrical Machines (ICEM).IEEE; Peyman, N., Toliyat, H.A., Goodarzi, A., Robust maximum torque per ampere (MTPA) control of PM-Assisted SynRM for traction applications (2007) IEEE Transactions on Vehicular Technology, 56 (4), pp. 1538-1545; Sawhney, K.A., Chakrabarti, A., Electrical machine design (2006) DhanpatRai and Co.; Krause, Paul, C., Analysis of Electric Machinery and Drive Systems, 2. , New York: IEEE press, 2002",,,,"Institute of Electrical and Electronics Engineers Inc.","2019 National Power Electronics Conference, NPEC 2019","13 December 2019 through 15 December 2019",,158564,,9781728144283,,,"English","National Power Electronics Conf., NPEC",Conference Paper,"Final","",Scopus,2-s2.0-85083073866

The nature of welding induces a variation in the geometric properties of the joint that connects the core to the faces. The geometric properties of the joint are the weld width, weld misalignment, and plate gap between the core and the faces. This paper aims to investigate the impact of the variation of the production-dependent geometric properties of the joint on the fatigue-relevant stresses. A secondary aim of this paper is to investigate the impact of contact between the core and the faces on the weld region stresses. Within this paper, the production of four sandwich panels is documented and the manufacturing-dependent geometric properties of their joints are quantified. In order to investigate the impact of the natural variation of the parameters, a parametric study based on finite element analyses is executed. The result of the parametric study shows, among several other findings, that misalignment of the weld line in relation to the core direction can lead to considerable increases in stresses, determinant for the fatigue life of the panel. © 2019, The Author(s).","Corrugated core; Fatigue; Joint geometry; Laser weld; Steel sandwich panel","Alignment; Geometry; Honeycomb structures; Manufacture; Sandwich structures; Welding; Welds; Corrugated core; Geometric properties; Joint geometry; Laser welds; Natural variation; Parametric study; Sandwich panel; Steel sandwich panels; Fatigue of materials",,,,,"VINNOVA","Regarding the manufacturing of the four sandwich panels, special acknowledgements are directed to Kleven Verft AS, Swerea KIMAB, and all partners in the research project INNODEFAB founded by VINNOVA and LIGHTer.

A novel method of non-destructive testing and evaluation of these pipes, while in service, is proposed in this paper. The method enables early detection of the root causes and pinpoints the location of the impending failure due to excess vibration as a result of cyclic force induced by the flow prior to condition-based maintenance procedures. The technique relies on the combined application of Operating Deflection Shapes (ODS) analysis and computational mechanics utilizing Finite Element Analysis (FEA), i.e. linear elastic stress analysis. The effect on vibration levels on the in-service pipes is assessed and verified. The effect of any change in the forces corresponding to changes in the Differential Pressure (DP) at a constant flow rate through the pipes can then be estimated. It was concluded that maintaining the differential pressure above some “critical” threshold ensures the pipe operates under the allowable dynamic stress for a theoretically “indefinite” life cycle. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.","Modal analysis; non-destructive testing; ODS; pipe; stress; vibrations","Bridge decks; Computational mechanics; Computer aided engineering; Condition monitoring; Life cycle; Modal analysis; Nondestructive examination; Pipe; Stress analysis; Stresses; Condition based maintenance; Dynamic characteristics; Flow induced vibrations; Non destructive evaluation; Non destructive testing; Non-destructive testing and evaluations; Operating deflection shapes; vibrations; Vibration analysis",,,,,,,,,,,,,,,,"Blevins, R.D., (1990) Flow-induced vibration, , 2nd, New York: Van trand Reinhold, ed; Chen, S.-S., (1987) Flow-induced vibration of circular cylindrical structures, , Washington: Hemisphere Pub.

Both distributed binary sensors and distributed fiber optic sensors are capable of detecting cracks that are wider than 0.2 mm in steel girders. The objective of this paper is to report the optimum placement of these sensors on the girder to detect smallest possible length of the crack. In this work, the optimized placement of crack sensors was studied using FEM of two typical medium-span simply supported steel girder bridges (Girder A, 30-m–long span, and Girder B, 22-m–long span). Using loads estimated from field monitoring data and FEM, a map of crack opening along the length of the crack was calculated for stable crack lengths. Using these maps and given the detectable crack opening of 0.2 mm, the optimum place to position a distributed crack sensor to detect the smallest crack length was determined. For Girder A, the sensor should be placed at 150 to 250 mm above flange at midspan and at one third from the support, and for the rest of the length of the girder, it should be placed at 200–300 mm above the bottom flange. For Girder B, the optimum placement for installation of binary sensor is estimated to be at 150 to 220 mm above the tension flange. The proposed method of calculation of placement can be used for installation of distributed sensors on other types of bridges. © 2019 John Wiley & Sons, Ltd.","binary crack sensor; crack detection; placement of distributed sensors;

A new model of high-order statically indeterminate structure was established with three orthogonal redundant forces acting at the junction between the girder and diaphragms. Emphasis is put onto the interaction between the girder and diaphragms, where a hypothetical bi-moment Bpi indicating all longitudinal redundant force components for diaphragm was proposed besides the moment Mpi for in-plane shear component. Simplified initial parameter method solutions for distortional angle and distortional warping stresses and displacements were derived based on the in-plane and out-of-plane compatibilities between the girder and diaphragms. Taking box girders with three and five intermediate diaphragms as an example, the proposed initial parameter method solutions have good agreement with the finite element analysis ones. Finally, distortional behavior under moving eccentric loads is investigated, resulting in a bowl-shaped curve for moment Mpi and an approximate trigonometric function for bi-moment Bpi. Results show that diaphragms have a stronger resistance on in-plane distortional shear for the loads in midspan than on ends. Plus, the thick diaphragm holds a stronger restraint on distortional warping deformations and stresses than the thin one. © The Author(s) 2019.","bi-moment; box girders; compatibility condition; diaphragms;

First, the cable anchorage system and cable measurement device were designed. Then, a series of model tests under the conditions of different preloading angles and different tensioning forces for hangers were carried out. Finally, the regularity of the torsional properties was revealed on the basis of the measured twist angle of the main cable. The experimental study shows that the transverse pre-deflected angle of the cable clamp has a decisive influence on the torsional angle of the main cable sections near the cable clamp, but for the main cable sections far from the pre-deflected cable clamp, this influence can almost be negligible. The torsional angle changes linearly within adjacent cable clamps. When inclined angle of the hanger is larger than the pre-deflected angle of the cable clamp, the cable clamp will cause the main cable section to twist in the positive direction, otherwise, the result is reverse. With the increase in the hanger force, the direction of hanger force passes through the cross-sectional center of the main cable, resulting in an unchanged twisting angle. In addition, a three-dimensional finite element model of the test specimen was established and used to analyze the influence of pre-deflected angle of a cable clamp on the torsion angle of the main cable, the same results can be found in finite element analyses in comparison with the test results. Therefore, a reasonable pre-deflected angle of cable clamp can be determined by the finite element model in the primary design state before the construction stage. © The Author(s) 2019.","main cable;

Porous ceramics with a sea urchin stereom structure on a micrometre scale and a nacre mineral bridge structure on a submicron scale have been fabricated via organic foam impregnation and controlled crystallisation. The microstructure and mechanical properties of biomimetic ceramics are, respectively, characterised using scanning electron microscopy and universal testing machine. Moreover, the porosity, reliability and grain boundary stress of biomimetic ceramics are calculated via Archimedes method, Weibull theory and finite element method, respectively. Results show that the ceramic produced in this work has a porosity of 88.16% and an average pore size of 284.65 μm. Mineral bridges of Al2TiO5 with a thickness of 30–230 nm are widely and randomly distributed in the grain boundary glass phase of Al2O3 and improved the compressive strength (2.32 MPa) and Weibull modulus (7.85) of ceramics by the multi-mechanisms of crack deflection, reducing maximum stress and homogenising stress on the grain boundary. These investigations would be of great value to the design and synthesis of novel biomimetic materials. © 2019","Biomimetic ceramic; Compressive property; Finite element method; Mineral bridge; Stereom; Weibull modulus","Alumina; Aluminum oxide; Biomimetic materials; Ceramic materials; Compressive strength; Finite element method; Gems; Grain boundaries; Mammals; Mechanical properties; Minerals; Pore size; Reliability theory; Scanning electron microscopy; Shellfish; Titanium compounds; Weibull distribution; Biomimetic preparation; Compressive properties; Microstructure and mechanical properties; Mineral bridge; Randomly distributed; Stereom; Universal testing machines; Weibull modulus; Biomimetic processes",,,,,"National Natural Science Foundation of China, NSFC: 51662006","The work is supported by the National Natural Science Foundation of China (NO. 51662006 ).",,,,,,,,,,"Chen, P.Y., Po, Y., Mckittrick, J., Meyers, M.A., Biological materials: functional adaptations and bioinspired designs (2012) Prog.

The proposed FSPM machine has the same rotor, PMs, and winding structure, but different stator yoke configuration with the conventional FSPM machine. In the proposed FSPM machine, the flux bridges are placed at the top of stator yoke as Cshaped, which can increase the main working harmonic field and reduce the flux barrier effect. First, the operational principle and influence of pole ratio on flux barrier effect are introduced. Then, three proposed FSPM machines with different pole ratios are investigated in torque characteristics considering the effects of split ratio and flux bridge width factor. Finally, the electromagnetic performances of the conventional and proposed FSPM machines are compared by finite element analysis (FEA) in terms of flux density, back-electromotive force (EMF), torque characteristics and overload capability. © 2019 IEEE.","C-shaped flux bridge; Compare; Flux bridge width factor; Flux switching permanent magnet (FSPM) machine; High pole ratio",,,,,,,,,,,,,,,,,"Zhu, Z.Q., Howe, D., Electrical machines and drives for electric, hybrid, and fuel cell vehicles (2007) Proceedings of the IEEE, 95 (4), pp. 746-765. , April; Cao, R., Cheng, M., Mi, C., Hua, W., Wang, X., Zhao, W., Modeling of a Complementary and Modular Linear Flux-Switching Permanent Magnet Motor for Urban Rail Transit Applications (2012) IEEE Trans. on Energy Conv., 27 (2), pp. 489-497. , June; Li, D., Qu, R., Li, J., Topologies and analysis of flux-modulation machines (2015) Proc.

The rotor topology is evolved from the conventional flat-type to a structure with long and smoothly curved iron-bridge edges on which the mechanical stress is distributed more evenly. The reduction of the maximum mechanical stress (MMS) could loosen the boundaries of optimization in the mechanical aspect, and hence, allowing the algorithm to explore a broader feasible region. A multi-objective optimization algorithm is combined with the proposed model in the design of a laminated 5kW, 50krpm high-speed IPMSM to achieve high-efficiency, low material cost, wide constant power speed range with practicable MMS. The optimization results show significant improvement in both electromagnetic and mechanical performances comparing to the case of using traditional flat-type model. © 2019 IEEE.","FEA; High speed; IPMSM; Mechanical stress; Multiphysics analysis; Optimization; Parametric model",,,,,,"Australian Research Council, ARC","This work is supported by the Australian Research Council Discovery Project Grant and the Research Training Program Scholarship.",,,,,,,,,,"Binder, A., Schneider, T., Klohr, M., Fixation of buried and surface mounted magnets in high-speed permanent magnet synchronous motors (2005) Fourtieth IAS Annual Meeting.

Normally, way of the precision of the crankshaft is to increase the blank diameter or the bridge size of flash, which result in high forging load, low service life of die, and material utilization. Therefore, a preformed dressing is designed in the balance slider of the pre-forging die. During the pre-forging period, a dressing will be formed in the balance slider, which is used to ensure the precision of the three-cylinder crankshaft in the final forging period. First, CAD models of the die and billet are established, then which are simulated by the Deform-3D software. The forging load and die wear depth are analyzed, and the area of the balance slider is under-filling. Second, a new pre-forging die is designed with a preformed dressing by the CAD software. Third, response surface analysis (RSA) and finite element technology are combined to optimize the pre-forging die of the three-cylinder crankshaft. According to variance analysis, the preformed dressing is not a significant influence factor on the die wear depth and load. Optimized factors’ R, D, H of the pre-forging die are 19 mm, 84 mm, and 6 mm, respectively. Fourth, the flash height of the final forging die is optimized, and the balance slider is filled well, and the die wear depth is reduced. Finally, physical experiment and practice forging are carried out to verify the optimal scheme of the finite element method (FEM), and the results of the experimental and finite element have a good consistency. © 2019, Springer-Verlag London Ltd., part of Springer Nature.","A preformed dressing;

In this study, an optimum first-order indeterminate strut-and-tie model that reflects all characteristics of the failure behavior is proposed for the rational design of reinforced concrete corbels with a shear span-to-effective depth ratio of less than 1.0. A load distribution ratio that transforms the indeterminate strut-and-tie model into a determinate model is also developed to help structural designers design reinforced concrete corbels using the strut-and-tie model methods of current design codes. For the development of the load distribution ratio, a material nonlinear finite element analysis of the proposed first-order indeterminate strut-and-tie model was conducted repeatedly by changing the combination of primary design variables of the corbels. To examine the validity of our results, the ultimate strengths of 294 reinforced concrete corbels tested to failure by other investigators were predicted using the proposed strut-and-tie model with the load distribution ratio, the existing determinate strut-and-tie models representing arch and truss load transfer mechanisms, and the American Concrete Institute 318 conventional design method based on a shear friction theory. The ultimate strengths predicted by the proposed strut-and-tie model agreed fairly well with the experimental results. The ratio of the experimental strength to the predicted strength (and coefficient of variation) was 1.09 (28.0%), implying that the proposed strut-and-tie model can represent the load transfer mechanisms of corbels most appropriately. © The Author(s) 2019.","corbel; load distribution ratio; reinforced concrete; strut-and-tie model; ultimate strength","Arch bridges; Concrete beams and girders; Electric power plant loads; American Concrete Institute; Coefficient of variation; Conventional design methods; corbel; Load distributions; Reinforced concrete corbels; Strut-and-tie model; Ultimate strength; Reinforced concrete",,,,,"Ministry of Education, MOE: NRF-2018R1D1A1B06041177; National Research Foundation of Korea, NRF","The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This research was supported by Basic Science Research Program through the National Research Foundation of Korea (NRF) funded by the Ministry of Education (NRF-2018R1D1A1B06041177).",,,,,,,,,,"Abdulhaleem, K.N., Gulsan, M.E., Cevik, A., Mechanical behavior of steel fiber-reinforced self-compacting concrete corbels after exposure to elevated temperatures (2018) Structural Concrete, 19 (6), pp. 1881-1894; (2010) Further Examples for the Design of Structural Concrete with Strut-and-Tie Models (SP-273), , Farmington Hills, MI, American Concrete Institute; Ali, M.A., White, R.N., Consideration of compression stress bulging and strut degradation in truss modeling of ductile and brittle corbels (2001) Engineering Structures, 23, pp. 240-249; (2018) AASHTO LRFD Bridge Design Specifications, , 8th ed., Washington, DC, AASHTO; (2014) Building Code Requirements for Structural Concrete (ACI 318–14) and Commentary (ACI 318R-14), , Farmington Hills, MI, ACI; Bergmeister, K., Breen, J.E., Jirsa, J.O., (1993) Detailing in structural concrete, , Austin, TX, The University of Texas at Austin,.

The scope is restricted to micromachined devices featuring a square-shaped membrane incorporating central symmetric thin-film devices. A microthermistor array probed spatial excess temperature variations while the main heat supply was alternatively established by optional heating resistors or by pronounced self-heating of the thermistor devices. Proper device designs enable leading edge transducer performance without sophisticated signal conditioning schemes. We found that a high azimuthal uniformity of flow magnitude transduction is tantamount to a precise azimuthal accuracy. The most advanced result gave a maximum azimuthal aberration of 0.17 and 1.7 degrees for 1 m/s and 10 m/s, respectively, while the corresponding magnitude uniformity amounted to 0.07% and 0.5%. Such excellent specifications exceed the need of ordinary meteorological applications by far. However, they are essential for, e.g., precise non-contact measurements of 2D relative movements of two quasi-planar surfaces via the related Couette flow in intermediate air gaps. The simulations predicted significantly better device characteristics than achieved by us in first experiments. However, this gap could be attributed to imperfect control of the flow velocity field by the measurement setup. © 2019 by the authors.

As the output of PEAs is limited to their sizes, a new kind of three stage motion amplification mechanism (MAM) is proposed to achieve a large workspace. Three kinds of MAMs, namely Scott-Russell mechanism, leverage mechanism, and half bridge-type mechanism are arranged in series or parallel to form a compact structure. The kinematic modeling of the XY stage is carried out using the pseudo rigid body model approach. Further, finite element analysis is conducted to evaluate its workspace and dynamic performance. The maximum displacements in x- and y-axes can reach 126.54 μm and 126.92 μm, respectively. The results show that the amplification ratio can reach around 12.7, which demonstrates the effectiveness of the three stage MAM. Moreover, the first natural frequency reaches 157.9 Hz. Hence, the simulation results demonstrate that the proposed nano positioning stage has a large workspace and a good dynamic performance. © 2019 IEEE.","Compliant mechanism; Flexure hinge; Motion amplification mechanism;

However, the real characteristics of the HFT such as magnetic inductance, leakage inductance and stray capacitance would influence the operation conditions of power converters. This paper analyzes the inductance characteristics of the HFT, focusing on the variation of the leakage inductance. To evaluate the magnitude of the leakage inductance, HFT samples wounded by nanocrystalline cores under 600 V/10 kW with various winding structures and air gap positions are simulated by finite element analysis (FEA) and tested by experimental measurements. The results show that the leakage inductance with the concentric windings is negligibly small, whereas the leakage inductance with the separate windings is so much larger that is even within the range of the phase-shift inductance required in DAB converters. On the other hand, the influence of air gaps on the leakage inductance is not evident not only in the concentric windings but also in the separate windings. A DAB prototype of 600 V/10 kW is designed and established, where the HFT with the separate windings has a leakage inductance adjusted to the magnitude of the phase-shift inductance required. The measurement results validate the feasibility that the phase-shift inductance could be substituted by the leakage inductance of the HFT. © 2019 IEEE.","high-frequency transformer; leakage inductance; magnetic integration; nanocrystalline","Electric machinery; Electric power distribution; Electric traction; Electric windings; High frequency transformers; Magnetic devices; Magnetic leakage; Nanocrystals; Separation; Winding; Concentric windings; Dual active bridge converter; Leakage inductance; Magnetic inductance; Magnetic integration; Nanocrystalline cores; Nanocrystallines; Operation conditions; Inductance",,,,,"National Natural Science Foundation of China, NSFC: 51877114","This work was supported by the National Natural Science Foundation of China under Grant 51877114.",,,,,,,,,,"Zhao, B., Song, Q., Liu, W., Sun, Y., Overview of dual-active- bridge isolated bidirectional DC-DC converter for high-frequency- link power-conversion system (2014) IEEE Transactions on Power Electronics, 29 (8), pp. 4091-4106. , Aug; Islam, M.R., Guo, Y., Zhu, J., A high-frequency link multilevel cascaded medium-voltage converter for direct grid integration of renewable energy systems (2014) IEEE Transactions on Power Electronics, 29 (8), pp. 4167-4182. , Aug; She, X., Huang, A.Q., Burgos, R., Review of solid-state transformer technologies and their application in power distribution systems (2013) IEEE Journal of Emerging and Selected Topics in Power Electronics, 1 (3), pp. 186-198. , Sept; Chen, Y., Zhao, S., Li, Z., Wei, X., Kang, Y., Modeling and control of the isolated DC-DC modular multilevel converter for electric ship medium voltage direct current power system (2017) IEEE Journal of Emerging and Selected Topics in Power Electronics, 5 (1), pp. 124-139. , March; Zhao, C., Power electronic traction transformer-medium voltage prototype (2014) IEEE Transactions on Industrial Electronics, 61 (7), pp. 3257-3268. , July; Shen, W., Wang, F., Boroyevich, D., Tipton, C.W., Loss characterization and calculation of nanocrystalline cores for high- frequency magnetics applications (2008) IEEE Transactions on Power Electronics, 23 (1), pp. 475-484. , Jan; Ouyang, Z., Zhang, J., Hurley, W.G., Calculation of leakage inductance for high-frequency transformers (2015) IEEE Transactions on Power Electronics, 30 (10), pp. 5769-5775. , Oct; Bahmani, M.A., Thiringer, T., Kharezy, M., Design methodology and optimization of a medium-frequency transformer for high- power DC-DC applications (2016) IEEE Transactions on Industry Applications, 52 (5), pp. 4225-4233. , Sept. -Oct; Mogorovic, M., Dujic, D., Medium frequency transformer leakage inductance modeling and experimental verification (2017) 2017 IEEE Energy Conversion Congress and Exposition (ECCE), pp. 419-424. , Cincinnati, OH; Mogorovic, M., Dujic, D., Sensitivity analysis of medium- frequency transformer designs for solid-state transformers (2019) IEEE Transactions on Power Electronics, 34 (9), pp. 8356-8367. , Sept; Cougo, B., Kolar, J.W., Integration of leakage inductance in tape wound core transformers for dual active bridge converters (2012) 2012 7th International Conference on Integrated Power Electronics Systems (CIPS), pp. 1-6. , Nuremberg",,,,"Institute of Electrical and Electronics Engineers Inc.","22nd International Conference on Electrical Machines and Systems, ICEMS 2019","11 August 2019 through 14 August 2019",,155694,,9781728133980,,,"English","Int.

In this study, a piezo-driven flexible actuator was developed based on a bridge-type mechanism as a vibrator for such a micropump film. The model of the flexible actuator under an external load is built based on an elastic model, and the displacement, driving force, and work efficiency are formulated in terms of the external loads, materials, and geometric parameters. The finite element method was used to verify this analytical model. An increase in the compliance of flexure hinges was found to improve the performances of the flexible actuator. The Young's modulus of materials decides force performances and the effects of external loads. Based on the elastic analysis, the proposed flexible mechanism, made of silicon, was optimized to realize optimal output displacement in a compact size and employed in the prototype of a micropump sucker with a weight of 1.3 g that produced a maximum negative pressure of 2.45 kPa. It can hold on a weight of 1.4 g. When the inlet of the proposed sucker is open, it has the maximum flow rate of 4 ml/min.

Those guidelines were based on field testing and finite element analysis conducted on existing RRFC bridges both in the field and in the lab. However, load rating is only one of the issues related to RRFCs as the main components are often classified as fracture critical members (FCMs)since there are only two flatcars in the cross section in most instances. Classifying the individual RRFCs as FCMs requires a rigorous hands-on inspection as per the Code of Federal Regulations, which greatly increases the long-term costs associated with these structures. Hence, while they are attractive to many owners due to their low initial costs and considerable strength, long-term costs due to inspection have deterred some owners from utilizing this viable and renewable alternative for low-volume applications. This paper presents the results of laboratory testing and non-linear finite element analysis of a railroad flatcar bridge specimen constructed with a composite reinforced concrete deck. The results confirm that RRFCs have considerable reserve strength and adequate load redundancy in a severely faulted state and need not be classified as FCMs if certain requirements are met. The paper also presents recommendations for load redistribution factors between primary members of RRFCs obtained through the experimental and verified by numerical studies. © 2019 Elsevier Ltd",,"Fracture; Railroads; Redundancy; Reinforced concrete; Analytical evaluation; Bridge specimens; Code of Federal Regulations; Laboratory testing; Load redistribution; Non-linear finite-element analysis; On-field testing; Reinforced concrete decks; Finite element method",,,,,,"This research was sponsored by the Indiana Local Technical Assistance Program (LTAP) .

Many finite element models have been developed to predict this failure mode. Research shows that the accurate modeling of interfaces between concrete and either internal steel or external fiber-reinforced polymer reinforcements is very important. This article presents a three-dimensional finite element model based on the smeared crack approach for predicting intermediate crack debonding failure of fiber-reinforced-polymer-strengthened reinforced concrete beams (including preloaded beams). In this model steel-to-concrete and fiber-reinforced-polymer-to-concrete interfaces are more expediently modeled. The finite element results agree well with experimental results on crack patterns, fiber-reinforced polymer strain distribution, and the variation of strain and deflection with load. This model can also simulate the fiber-reinforced polymer debonding process of the beam and the response of the residual beam after the fiber-reinforced polymer reinforcement has separated from the reinforced concrete beam. In addition, parameters’ analyses are further conducted to find the differences between the two-dimensional and three-dimensional models. Simulations of fiber-reinforced polymer-plated slabs or beams with additional anchors are mostly three-dimensional problems, and their focus is also on intermediate crack debonding. This model can be used to simulate fiber-reinforced-polymer-plated slabs or beams with additional anchors such as U-jacket strips or mechanically fastened fiber-reinforced polymer strengthening systems in future research. © The Author(s) 2019.","bonding; concrete beams; fiber-reinforced polymer; finite element method; preloaded beams","Anchors; Bonding; Composite bridges; Concrete beams and girders; Cracks; Debonding; Fiber bonding; Fiber reinforced plastics; Finite element method; Polymers; Reinforced plastics; Steel fibers; Concrete beam; Fiber reinforced polymers; preloaded beams; Reinforced concrete beams; Strengthening systems; Three dimensional finite element model; Three-dimensional model; Three-dimensional problems; Reinforced concrete",,,,,"National Natural Science Foundation of China, NSFC: 51878664; National Key Research and Development Program of China, NKRDPC: 2017YFC0703506","The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: The authors are grateful for the financial support received from the National Natural Science Foundation of China (Grant No. 51878664) and the National Key R&D Program of China (National Key Project No. 2017YFC0703506).

The purpose of this study includes investigating inelastic buckling behavior of a cylindrical shell under uniaxial compression at an elevated temperature and considering geometrically and materially non-linear analysis with imperfections. Selected parameters of the analytical model include fire exposure condition, slenderness ratio, and D/t (diameter/thickness ratio); compressive buckling behavior characteristics of a cylindrical shell were obtained using ABAQUS (a commercial FE Program). The critical buckling strength and mode shape of the cylindrical shell were analyzed through 3D modeling to present basic data for reasonably efficient design.

The strips were bonded to the concrete surface and additionally fixed with fan-type carbon-fibre-reinforced polymer anchors. The model was developed using the results of 14 pull tests on concrete blocks strengthened with variously sized and anchored strips. The anchors were represented by increasing the bonding strength in the anchor contact area. The numerical results were compared with experimental results and showed good correlation. The model was then used to investigate the influence of strip width and length, number of anchors and concrete strength on load-transfer behaviour. Finally, a mathematical model was proposed for calculating the bond strength between concrete and a bonded and anchored carbon-fibre-reinforced polymer strip. © ICE Publishing: All rights reserved.","anchors & anchorages; composite structures; concrete structures","Anchors; Bridge decks; Carbon fiber reinforced plastics; Composite structures; Concrete construction; Concretes; Fiber reinforced plastics; Polymers; Reinforced plastics; Reinforcement; Tensile strength; Bonding strength; Carbon fibre reinforced polymer; Concrete strength; Concrete surface; Finite element software; Good correlations; Load transfer mechanism; Numerical results; Carbon fibers; analytical framework; anchor; composite; concrete structure; finite element method; loading; numerical model; polymer; software",,,,,,,,,,,,,,,,"ACI (American Concrete Institute) (2002) ACI 318M-02/318RM-02: Building code requirements for structural concrete and commentary.

But for hangers with shock absorber, the existing tension estimation methods are not suitable because they are based on a single cable model and cannot consider the effect of shock absorbers. To this end, the effect of the shock absorber is taken into account by using the degree-of-freedom condensation method, and a finite element method for tension estimation of hangers with shock absorber is proposed in this paper. Finally, the proposed method is applied in the Aizhai Bridge and Huangpu Pearl River Bridge to estimate the tension of hangers with shock absorber, the tested results show that as compared with other methods, the proposed method is a more accurate and convenient method for engineering application. © 2019 Quan Gan, et al.","Finite element method;

Concrete bearing strength is depending on ratio of unloaded-to-loaded area and compressive strength of concrete. However, the effect of concrete block height on bearing strength of concrete is not included. Hence, the effect of different heights on concrete bearing strength were investigated using numerical modelling. The three-dimensional finite element model (FEM) for nonlinear analysis of concrete bearing were developed and analyzed in ABAQUS/Explicit. The FE models were validated based on pre-existing experimental results. The confinement effect and structural ductility of concrete blocks with different heights were evaluated. The FE results indicate that the level of internal confinement and the structural ductility of concrete blocks were affected significantly as increasing of concrete block heights. The bearing force for the concrete block with 150mm high was significantly dropped to 55% as compare to control specimen of 50mm high. © Published under licence by IOP Publishing Ltd.",,"ABAQUS; Bridges; Compressive strength; Ductility; Nonlinear analysis; Numerical models; Structural design; Tensile strength; Bearing strengths; Compressive strength of concrete; Confinement effects; Design characteristics; Different heights; Structural ductility; Structural support; Three dimensional finite element model; Concretes",,,,,"Universiti Teknologi MARA, UiTM: 126/2017, 600-IRMI/DANA KCM 5/3/LESTARI","The authors gratefully acknowledge the financial supports from Universiti Teknologi MARA (UiTM) Shah Alam, Selangor, Malaysia under Research Grant 600-IRMI/DANA KCM 5/3/LESTARI (126/2017).

When cast-in-place concrete decks are used with staged construction, the concrete deck must cure while subjected to loads and displacements caused by the adjacent traffic using the same structure. Traffic-induced displacements and vibrations may damage the freshly placed concrete, its bond with the embedded reinforcement, or the integrity of the concrete joint. To determine the effects, if any, of staged construction practices on long-term bridge performance, this research examined bridge decks in Wisconsin that were constructed or widened using staged construction through visual inspection, field monitoring, and finite-element modeling. Some minor defects were observed in the field inspections of slab-on-girder bridges, such as underconsolidated concrete in the construction joint region and leakage through the joint itself. The inspected haunched-slab bridges showed severe deterioration at the construction joints. Field-measured differential displacements were small, with a maximum of 1.1 mm (0.043 in.), both during construction and several weeks after. Finite-element modeling confirmed these observations. Modeling results indicated that as long as nominal stiffness was provided by the deck or even the formwork between girders adjacent to the longitudinal joint, these deflections were unlikely to cause deterioration. Longer-span bridges may experience larger differential displacements across the joint, but these may be controlled by preventing larger vehicles from using the lane adjacent to the fresh concrete for approximately one day. © 2019 American Society of Civil Engineers.","Bridge decks; Field inspections; Staged construction","Beams and girders; Bridge decks; Deterioration; Finite element method; Inspection; Bridge performance; Construction joints; Differential displacements; Embedded reinforcements; Field inspection; Longitudinal joint; Slab-on-girder bridge; Staged construction; Cast in place concrete",,,,,,,,,,,,,,,,"(2012) AASHTO LRFD Bridge Design Specifications, , AASHTO. 6th ed.

In the present paper, some fundamental numerical studies are carried out for the structural analysis of the trimaran using the whole ship model, particularly focusing on the strength of the cross deck. First, the hydrodynamic pressure for wave loads acting on the trimaran hulls is predicted based on the potential theory. These are input loads on the structure analysis of the trimaran, and the validity of the present approach is discussed with results of towing tank tests. Additionally, the load transfers should be done appropriately for the structure analysis. This is because the difference between the grid size of the hydrodynamic analysis and that of structure analysis, for example, finite-element (FE) analysis, may lead to a drop of computational accuracy. Next, the global strength of the target trimaran is discussed using the design loads by the rules. Finally, the local strength analysis using FE model is studied and the elastic behavior of the cross-deck structure is investigated to collect the useful properties for the cross-deck design. © 2018, JASNAOE.","Cross-deck structure; FEM; Splitting and torsional deformation; Stress analysis; Trimaran","Bridge decks; Computation theory; Decks (ship); Finite element method; Hydrodynamics; Ship models; Stress analysis; Structural loads; Computational accuracy; Deck structures; Fundamental studies; Hydrodynamic analysis; Hydrodynamic pressure; Qualitative knowledge; Torsional deformations; Trimaran; Structural design",,,,,,,,,,,,,,,,"Branchard, T., Chunhua, T., Rule for the classification of trimarans (2007) J Naval Eng, 44 (1), pp. 1-51; Shehzad, K., Huilong, R., Zhen, C., Khurram, A., Global strength assessment of trimaran structure (2012) Adv Mater Res, 538-541 (4), pp. 2860-2863; Huilong, R., Shehzad, K., Chunbo, Z., Khurram, A., Fatigue assessment of trimaran structure based on simplified procedure (2012) Key Eng Mater, 525-526, pp. 333-336; Fuentes, D., Salas, M., Tampier, G., Troncoso, C., (2015) Structural design and optimization of an aluminium trimaran, analysis and design of marine structures, , Taylor & Francis Group, London; Zhen, C.B., Ren, H.L., Feng, G.Q., Li, C.F., Study on fatigue strength of trimaran cross-deck structure based on spectral method (2012) Appl Mech Mater, 148-149, pp. 393-396; Fang, M.C., Chen, T.Y., A parametric study of wave loads on trimaran ships traveling in waves (2008) Ocean Eng, 35, p. 749762; Xu, M., Zhang, S.L., A numerical study on side hull optimization for trimaran (2011) J Hydrodyn, 23 (2), pp. 265-272; Register, L., (2015) Rules for the Classification of Trimarans, , Lloyd’s Register; Dobashi, J., Resistance characteristics of the high speed multihull ships.

This approach utilizes the recursive formats of impulse-response-function expressions for bridge's aeroelastic forces. Nonlinear dynamic equilibrium equations are iteratively solved by using the restart technique in ANSYS, which enable the equilibrium state of system to get back to last moment absolutely during iterations. The condition for the onset of flutter instability becomes that, at a certain wind velocity, the amplitude of vibration is invariant with time. A long-span suspension bridge was taken as a numerical example to verify the applicability and accuracy of the proposed method by comparing calculated results with wind tunnel tests. The proposed method enables the bridge designers and engineering practitioners to carry out time-domain flutter analysis of bridges in commercial FE package ANSYS.

Therefore. a structure design and optimization method for crossbeam based on orthogonal experimental design. improved fuzzy comprehensive evaluation and size sensitivity analysis was proposed. According to the multi-factor and multi-level characteristics of crossbeam structure design, eight kinds of representative parameter combinations were selected as the structure design scheme of crossbeam by orthogonal experimental design. The improved fuzzy comprehensive evaluation method was used to process the finite element simulation data. so that the optimum selection scheme of crossbeam with parameters combination “box in box - well - 20 mm - linear guideway” was determined. And the sensitivity analysis and optimization of its key design sizes were carried out to obtain the specific of crossbeam structure design size. After optimization, the static performance and anti-vibration performance of crossbeam were improved obviously while the lightweight design of crossbeam was also realized, which played a guiding role in the actual manufacture of machine tool crossbeam.

In this work, we develop a continuum mechanics framework to explore the conformational states of MscS during the gating transition. A complete gating transition trajectory from the closed to the open state along with partially open intermediates is obtained, and the open structure is close to the available structural model from crystallographic studies. The computational efficiency of the modeling framework makes it possible to explore the roles of various structural elements (e.g., loops that connect transmembrane helices) and specific interactions in the gating transition. It is observed that removing either the Asp62-Arg131 salt bridge or the Phe68-Leu111 non-polar interaction leads to essentially non-conducting structures even with a membrane tension close to the lysis limit. The loop connecting TM2 (the second transmembrane helix) and TM3 is found to be essential for force transmission during gating, while the loop connecting TM1 and TM2 does not make any major contribution. Based on the different structural evolutions observed when the TM3 kink is treated as a loop or a helical segment, we propose that the helical propensity of the kink plays a central role in inactivation; i.e., under prolonged sub-threshold membrane tension, transition of the initially flexible loop to a helical segment in TM3 may lead to MscS inactivation. Finally, the gating transition of MscS under different transmembrane voltages is explored and found to be essentially voltage independent. Collectively, results from the current continuum mechanics analysis provide further insights into the gating transition of MscS at structural and physical levels, and specific predictions are proposed for further experimental investigations. © 2018 Elsevier Ltd","Continuum mechanics; Gating mechanism; Inactivation; Mechanobiology; Mechanosensitive channel of small conductance","Computational efficiency; Escherichia coli; Flowcharting; Threshold voltage; Crystallographic studies; Escherichia coli (E. coli); Experimental investigations; Gating mechanisms; Inactivation; Mechano-biology; Mechanosensitive channel; Transmembrane helices; Continuum mechanics; arginine; aspartic acid; ion channel; leucine; phenylalanine; Escherichia coli protein; ion channel; MscS protein, E coli; Article; channel gating; conceptual framework; conductance; conformational transition; electric potential; molecular interaction; molecular mechanics; molecular model; pore size; priority journal; structural model; tension; alpha helix; cell membrane; chemistry; cytology; electrophysiology; Escherichia coli; finite element analysis; mechanotransduction; metabolism; Cell Membrane; Electrophysiological Phenomena; Escherichia coli; Escherichia coli Proteins; Finite Element Analysis; Ion Channel Gating; Ion Channels; Mechanotransduction, Cellular; Models, Molecular; Protein Conformation, alpha-Helical",,"arginine, 1119-34-2, 15595-35-4, 7004-12-8, 74-79-3; aspartic acid, 56-84-8, 6899-03-2; leucine, 61-90-5, 7005-03-0; phenylalanine, 3617-44-5, 63-91-2; Escherichia coli Proteins; Ion Channels; MscS protein, E coli",,,"2018ZDXM-GY-131; National Natural Science Foundation of China, NSFC: 11572238, 11872302","X.

Vulnerable response of steel diaphragms in recent strong ground motions has encouraged the researchers to work on their application as seismic force reducing devices for design and retrofitting of bridges. This study is an attempt to achieve a ductile diaphragm behavior under seismic actions by using existing internal end plate diaphragm of steel tub girder bridges. Considerable elastic stiffness and dominant shear behavior of the end diaphragm has made it a suitable choice for such behavior under seismic actions. Nonlinear quasi-static analyses using nineteen different finite element models were conducted to evaluate the internal end diaphragm behavior with different configurations and boundary elements. Moreover, plastic analyses using tension strips theory were used to derive formulations for design base shear and tension field inclination of different models. The calculated values were in agreement with the results of finite element models. As a result, remarkable response modification factor was derived for the proposed ductile system. In addition, nonlinear time history analyses were used to prove the ductile behavior of the selected models under real moderate and strong ground motions. © 2018 Elsevier Ltd","Ductile diaphragm; Internal end diaphragm; Seismic design; Tub girder bridge","Bridges; Earthquakes; Finite element method; Seismic design; Surface tension; Boundary elements; Design base shears; Elastic stiffness; Girder bridges; Nonlinear time history analysis; Quasi static analysis; Response modification factors; Strong ground motion; Diaphragms",,,,,,,,,,,,,,,,"Guide Specification for LRFD Seismic Bridge design (2011), 2nd edition Washington, D.C; Seismic Retrofitting Manual for Highway Structures; Part 1- Bridges.

However, local buckling, global buckling, or a combination of both are considered a main reason for a significant loss of strength and ductility in these columns, or possibly a full collapse under severe earthquakes. This paper investigates the hysteretic behavior of circular thin-walled steel columns with uniform and graded thickness under constant axial and bidirectional cyclic lateral loading. The paper's analysis is carried out using a finite-element model (FEM) which considers both material and geometric nonlinearity. The accuracy of the employed FEM is validated based on experimental results. Then, five different configurations of graded-thickness thin-walled columns with the size and volume of material equivalent to a uniform column are investigated. The graded-thickness columns are found to make significant improvements in ultimate strength, ductility, and post-buckling behavior as compared to their counterpart uniform column, emphasizing the sectional configuration in the graded-thickness columns. © 2019 American Society of Civil Engineers.",,"Buckling; Ductility; Hysteresis; Bi-directional cyclic loading; Cyclic lateral loading; Geometric non-linearity; Hysteretic behavior; Postbuckling behavior; Speed of constructions; Structural advantage; Thin walled column; Thin walled structures",,,,,,,,,,,,,,,,"Al-Kaseasbeh, Q., Mamaghani, I.H.P., Buckling strength and ductility evaluation of thin-walled steel tubular columns with uniform and graded thickness under cyclic loading (2018) Journal of Bridge Engineering, 24 (1), p. 04018105; Anderson, E.L., Mahin, S.A., An evaluation of bi-directional earthquake shaking on the provisions of the aashto guide specifications for seismic isolation design (2004) Proc. 13th World Conf.

However, the use of AM to produce Fibre Reinforcement Thermoplastics (FRTP) parts means that structural applications with safety requirements are envisaged, demanding reliable NDT methods. This paper presents experimental results and numerical simulation by Finite Element Method (FEM) of the NDT inspection of different parts of polymeric and RFTP composite materials. The parts were produced by FDM Additive Manufacturing and different delamination defects were introduced at different positions and with different dimensions and morphologies. Two different NDT techniques were used, exploiting different inspection parameters: air-coupled ultrasound, using frequencies between 50 and 400 kHz and active transient thermography, in both reflection and transition modes. The influence of the curvature of the parts was analysed, from the experimental point of view, and the results were compared with different numerical simulation strategies. It was shown that, both NDT techniques can detect the defects, with good spatial resolution, being the thermography reflection mode the fastest and expedite for curvature parts. The numerical simulation corroborates the experimental results allowing a deeper insight on the physical phenomena involved. Copyright © British Institute of Non-Destructive Testing, NDT 2019.

Bridges that are compiled of single span prestressed girders, appear to have insufficient resistance to diagonal tension cracking. This concerns bridges that do not contain sufficient stirrups. Consequently, diagonal tension cracking could result in an abrupt brittle failure. However, the assessments are performed using the Eurocode model and there is doubt about its accuracy. In this research the accuracy of the Eurocode model is determined by comparing predicted resistances with experimentally found resistances. Moreover the stress distribution according to the Eurocode model is compared with the stress distribution of a linear elastic finite element analysis. Based on the comparison, an alternative model is suggested, that predicts the resistance to diagonal tension cracking more accurately. © 2019 Taylor & Francis Group, London, UK.",,"Codes (standards); Prestressed beams and girders; Stress concentration; Structural design; Brittle failures; Diagonal tension; Eurocodes; Existing bridge; Linear elastic finite element analysis; Netherlands; Prestressed girder; Traffic loads; Cracks",,,,,,,,,,,,,,,,"(2018) Building Code Requirements for Structural Concrete (ACI 318-08) and Commentary, pp. 318R-08R. , Farmington Hills, American Concrete Institute; (2005) Eurocode 2: Design of Concrete Structures-Part 1-1: General Rules and Rules for Buildings; Choulli, Y., (2005) Shear Behaviour of Full-Scale Prestressed I-Beams Made with Self Compacting Concrete; Elzanaty, A.H., Nilson, A.H., Slate, F.O., Shear capacity of prestressed concrete beams using high strength concrete (1986) Journal of the American Concrete Institute, 83, pp. 359-368; Hanson, J.M., Hulsbos, C.L., Ultimate Shear tests of prestressed concrete I-beams under concentrated and uniform loadings (1964) PCI Journal, pp. 15-28; Hussein, A.A., (1998) Behaviour of High-Strength Concrete Ubder Bi-Axial Loading Conditions; Reineck, K.H., Kuchma, D.A., Fitik, B., (2012) Erweiterte Datenbanken Zur Überprüfung Der Querkraftbemessung für Konstruktionsbetonbauteile Mit Und Ohne Bügel, , DAfStb-Heft",,"Zingoni A.",,"CRC Press/Balkema","7th International Conference on Structural Engineering, Mechanics and Computation, 2019","2 September 2019 through 4 September 2019",,236239,,9781138386969,,,"English","Adv.

Many efforts have been made to strengthen and repair RC structures using Fiber Reinforced Polymers (FRP). A lot of studies have been done on Columns and beam or beam/columns join to enhance the efficiency of FRP for seismic strengthening. But few research concern the join between wall and slab. The aim of this study is to create a FE model able to predict the mechanical behavior of RC wall/slab connections by using Carbon Fiber Reinforced Polymers. Chalot et al. [1] investigate experimentally the mechanical behavior of 4 large scale specimens with a reference join and 3 strengthened by FRP. The numerical analyses is conducted utilizing the FE software ABAQUS. The 3D FEM model geometry reproduced the actual geometry of the experiments, as well as the simulation used the same boundary conditions and loading as in the experimental program. We focus our study on a set of systematic procedures for finite element model calibration and parametric evaluation that enable robust simulation of the RC wall/slab connections under monotonic loading with high fidelity using explicit time-stepping time-history analysis methods. The obtained results reveal the overall mechanical behavior of the RC wall/slab connections reinforced by using Carbon Fiber Reinforced Polymers. Copyright © 2019 COMPDYN Proceedings.

In this study, firstly, the analytical formulas for the global and interactive shear buckling stresses of CSWs are deduced by the Galerkin method. Simplified formulas for the global shear buckling coefficient kg for a four-edge simple support, for a four-edge fixed support, for two edges constrained by flanges fixed and the other two edges simply supported, and an interactive shear buckling coefficient table are given. Secondly, an elastic finite element analysis is carried out to verify the analytical formulas and to study the influence of geometric parameters on the shear buckling stress of CSWs. Finally, a design formula for the shear strength of CSWs which adopts the formulas for the global and interactive shear buckling stresses proposed in this paper is assessed. From a comparison between the shear strength calculated by this design formula, calculated by four previous design formulas and measured in a series of published test results, it is found that the considered design formula provides good predictions for the shear strength of CSWs and can be recommended. © 2019 by The Hong Kong Institute of Steel Construction.","Corrugated steel web; Finite element analysis; Galerkin method; Global shear buckling; Interactive shear buckling; Shear strength","Finite element method; Galerkin methods; Shear strength; Analytical formulas; Corrugated steel webs; Design formulae; Shear buckling; Shear buckling coefficients; Simplified formula; Simply supported; Trapezoidal corrugated steel webs; Buckling",,,,,"National Natural Science Foundation of China, NSFC: 51378106; China Scholarship Council, CSC","The supports from the National Natural Science Foundation of China (grant no.51378106) and the China Scholarship Council are gratefully acknowledged.",,,,,,,,,,"Hamilton, R.W., (1993) Behavior of Welded Girders with Corrugated webs”, , Ph.D. Thesis, Orono, USA; Leblouba, M., Junaid, M.T., Barakat, S., Altoubat, S., Maalej, M., Shear buckling and stress distribution in trapezoidal web corrugated steel beams (2017) Thin-Walled Structures, 113, pp. 13-26; Eldib, M.H., Shear buckling strength and design of curved corrugated steel webs for bridges (2009) Journal of Constructional Steel Research, 65 (12), pp. 2129-2139; Timoshenko, S.P., Gere, J.M., (1961) Theory of Elastic Stability, , 2nd ed., McGraw-Hill Book Company, New York, USA; Aggarwal, K., Wu, S., Papangelis, J., Finite element analysis of local shear buckling in corrugated web beams (2018) Engineering Structures, 162, pp. 37-50; Easley, J.T., McFarland, D.E., Buckling of light-gage corrugated metal shear diaphragms (1969) Journal of the Structural Division, 95 (7), pp. 1497-1516; Easley, J.T., Buckling formulas for corrugated metal shear diaphragms (1975) Journal of the Structural Division, 101 (7), pp. 1403-1417; Bergman, S., Reissner, H., Neuere probleme aus der flugzeugstatik–über die knickung von wellblechstreifen bei schubbeanspruchung (1929) Zeitschrift für Flugzeugtechnik Und Motorluftschiffahrt, 20 (18), pp. 475-481; Hlavacek, V., Shear instability of orthotropic panels (1968) Acta Technica CSAV, 1, pp. 134-158; Peterson, J.P., (1960) Investigation of the Buckling Strength of Corrugated Webs in Shear, , National Aeronautics and Space Administration, New York; Bergfelt, A., Edlund, B., Leiva, L., Trapezoidally corrugated girder webs: Shear buckling, patch loading (1985) Ing.

This study put forward an analysis model of reinforced concrete T-shaped girder carriageway plate girders to reveal the law of the influences of internal factors, such as length-width and thickness-width ratios of two-and one-way slabs, on the fatigue performance of carriageway plates. The physical girder space model was established using the Midas/FEA finite element software. The correlation between the fatigue stress level, length-width ratio, and thickness-width ratio of carriageway plates and the fatigue performance of carriageway plates of ribbed-girder bridges was analyzed using traditional fatigue analysis methods based on the S-N curve and Miner linear cumulative damage theory. The fatigue life and rupture areas were determined. The change rules of fatigue life and damage degrees of structure girders under different influencing factors were determined. Results show that a significant negative correlation exists between the length-width ratio and fatigue life of carriageway plate when the length-width ratio of one-way slabs ranges from 4.0 to 6.0. The fatigue life decreases linearly with the increase in the length-width ratio when the length-width ratio of two-way slabs ranges from 1.0 to 1.9. The anti-fatigue performance of two-way slabs is stronger than that of one-way slabs. In addition, setting the thickness-width ratio of a carriageway plate between 0.07 and 0.08 is economically reasonable. This study provides a certain reference value for the further perfection of the anti-fatigue design of carriageway plates of reinforced concrete ribbed-girder bridges. © 2019 School of Science, IHU.

To this end, the upper-bound semi-empirical relationships proposed in [1] are considered for the estimation of the seismic performance, expressed in terms of the maximum and permanent values of the deck drift ratio attained during and at the end of the seismic event. These drifts were related to the period ratio Teq/T0 between the fundamental periods of the deck-pier-caisson-soil system and of the soil column in free-field conditions. The deck drift and the period ratios were extracted from the results of an extensive parametric study, where 14 different systems were subjected to 6 real high-intensity seismic records. In the parametric study, 3D dynamic analyses were performed with the Finite Element Method in the time domain, in terms of effective stresses but assuming undrained conditions and adopting an elastic-plastic constitutive model to reproduce the irreversible soil behaviour under cyclic loading. As 3D dynamic numerical analyses are not expected to become an every-day design tool, the period ratios Teq/T0 are evaluated through empirical and analytical relationships available in the literature as well and then compared with the ratios obtained from the parametric study, to assess the possibility of using simplified relationships while still getting a reliable estimate of the deck drift ratio. It is shown that these relationships can be profitably adopted provided that a fair estimate of the equivalent shear wave velocity, depending on the intensity of the seismic inputs, is used.

Indeed, any damage in adhesives will affect the efficiency and the performance of the repaired structure by composite patches. In this paper, two different adhesive shapes were numerically investigated, using finite element method in order to estimate the damage zone area on the adhesive bonded composite repair in 5083 marine grade aluminum alloy and its effect on the efficiency and performance of the repaired structure. The obtained results proved that the circular shape causes less damage than the rectangular one for the three crack lengths chosen. Moreover, both shapes of adhesive maintain their performance repair without disband risk and without reaching the critical value defined by Ban and co-authors (Dr=0.2474). Furthermore, it is concluded that the damage zone increases with the increase of the adhesive thickness and the decrease of the patch thickness and the use of circular shape is more effective than the rectangular one for the configurations and loading conditions studied. © 2019 Trans Tech Publications Ltd, Switzerland.","Adherence; Aluminum alloy; Composite patch; Damage zone; FEM","Adhesives; Efficiency; Fiber optic sensors; Finite element method; Repair; Stress intensity factors; Adherence; Adhesive thickness; Aluminum structures; Bonded composite repairs; Composite patches; Damage zones; Efficiency and performance; Numerical investigations; Aluminum alloys",,,,,,,,,,,,,,,,"Thakur, S.K., Gupta, M., Improving mechanical performance of Al by using Ti as reinforcement (2007) Compos Part A Appl.

However, the simulation results from an FE model are usually different from an as-built structure. To improve the accuracy of the FE model, selected structural parameters are to be updated, which is known as FE model updating. This paper discusses the updating of an FE model based on a steel pedestrian bridge on Georgia Tech campus. By setting structural parameters as optimization variables, FE model updating is formulated as optimization problems to minimize the difference between experimental and simulated frequency-domain modal properties. Two modal property difference formulations are presented, one using modal assurance criterion (MAC) values and the other using direct difference between mode shapes. For each updating formulation, derivative Jacobian of the objective function is derived in detail.

The box girder is a scaled model of a ship hull with large-span deck. The results obtained by three methods shows that the finite element method produces an ultimate bending moment slightly (1.8%) larger than the experimental one, while the Smith method gives a smaller (7.5%) one as compared to experiment. In addition, based on the Smith method, the collapse behavior of the cross section is analyzed to provide more detailed information for the collapse process. The failure stresses of a typical component, the deck girder located in the middle of target deck area, are obtained from experiment and Smith method, and are compared, showing good agreement. The research work of this paper shows that Smith method has been applied successfully on large-span deck structures in order to provider collapse sequence and identify the weakest local component in ship design process. © 2019 Taylor & Francis Group, London.",,"Beams and girders; Box girder bridges; Decks (ship); Hulls (ship); Iterative methods; Ocean structures; Structural design; Collapse behavior; Deck structures; Failure stress; Nonlinear finite element method; Progressive collapse analysis; Scaled modeling; Ship design process; Ultimate strength; Finite element method",,,,,,,,,,,,,,,,"Andrić, J., Kitarović, S., Bičak, M., IACS incremental-iterative method in progressive collapse analysis of various hull girder structures (2014) Brodogradnja, 65 (1), pp. 65-77; Bass, D.W., Molyneux, W.D., McTaggart, K., (2004) Simulating Wave Action in the Well Deck of Landing Platform Dock Ships Using Computational Fluid Dynamics, , Warship.

This paper focuses on finding the most influential distortion parameter that dictates the fatigue strength at the butt weld of a laser-hybrid welded 4 mm thin ship deck panel. A FEA based sensitivity analysis method is employed to identify the influence of the distortion parameters. The results from the experimental validation showed that the distortions of the distorted deck plate on either side of the butt weld could be simplified with 4-point and 3-point splines on longitudinal and transversal direction, respectively. The most important distortion parameters are local angular misalignment, the distortion magnitude and location of local maximum distortion close to the butt weld. The distortion parameters further away from the weld has a minor influence on the structural stress at the butt weld. Furthermore, the results showed that the local angular misalignment can independently provide a better estimate of stress magnification factor km compared to any other distortion parameters. © 2019 Taylor & Francis Group, London.",,"Alignment; Bridge decks; Butt welding; Decks (ship); Ocean structures; Plates (structural components); Sensitivity analysis; Welds; Angular misalignment; Distortion parameters; Experimental validations; Fatigue behavior; Fatigue strength; Magnification factors; Structural stress; Transversal directions; Fatigue of materials",,,,,,,,,,,,,,,,"(2016) Guidelines for Fatigue Assessment of Steel Ships and Offshore Units, pp. 98-103; (2015) DNVGL-CG-0129: Fatigue Assessment of Ship Structures, , https://rules.dnvgl.com/docs/pdf/DNVGL/CG/2015-10/DNVGL-CG-0129.pdf; Eggert, L., Fricke, W., Paetzold, H., Fatigue Strength of Thin-Plated Block Joints with Typical Shipbuilding Imperfections (2012) Welding in the World; Fricke, W., Feltz, O., Consideration of Influence Factors between Small-Scale Specimens and Large Components on the Fatigue Strength of Thin-Plated Block Joints in Shipbuilding (2013) Fatigue and Fracture of Engineering Materials and Structures, 36 (12), pp. 1223-1231. , https://doi.org/10.1111/ffe.12058; Fricke, W., Remes, H., Feltz, O., Lillemäe, I., Tchuindjang, D., Reinert, T., Nevierov, A., Fatigue Strength of Laser-Welded Thin-Plate Ship Structures Based on Nominal and Structural Hot-Spot Stress Approach (2015) Ships and Offshore Structures, 10 (1), pp. 39-44. , https://doi.org/10.1080/17445302.2013.850208; Lloyd, G., (1996) Comparison of No.47 Shipbuilding and Repair Quality Standard Production Standard of the German Shipbuilding Industry Part a – Shipbuilding and Repair Quality Standards for New Construction 1.

This study focuses on the flexural behavior of timber beams externally reinforced with carbon fiber reinforced polymer (CFRP) composites at the tension face and the responses of the fundamental principal compression arch because of confinement from end anchorage. Beams of three different types of timber are studied. All the beams had the same length, width, and span length and were tested under four-point loading. Different CFRP lamination techniques were adopted, with and without U-clamp confinement as end anchorage, to investigate the flexural capacity enhancement of CFRP strips as reinforcement for timber beams. The profile of the principal compression arch is estimated experimentally from fundamental flexural strain-along-depth phenomena by post-processing high definition images extracted from test videos employing digital image correlation technique (DICT) in the MATLAB R2011a framework. Similar responses were found from finite element analysis using ANSYS 11.0. Effective confinement of the principal compression arch produced significant enhancements of flexural capacities and stiffness in the strengthened timber beams. © National Academy of Sciences: Transportation Research Board 2019.",,"Anchorages (foundations); Arch bridges; Arches; Fiber reinforced plastics; Laminating; Reinforced plastics; Reinforcement; Timber; Wooden beams and girders; Carbon fiber reinforced polymer composite; Digital image correlation technique; Effective confinements; Flexural behavior; Flexural capacity; High definition; Post processing; Structural elements; Carbon fiber reinforced plastics",,,,,,,,,,,,,,,,"Khelifa, M., Celzard, A., Oudjene, M., Ruelle, J., Experimental and Numerical Analysis of CFRP-strengthened Finger-jointed Timber Beams (2016) International Journal of Adhesion and Adhesives, 68, pp. 283-297; Ghanbari Ghazijahani, T., Jiao, H., Holloway, D., Composite Timber Beams Strengthened by Steel and CFRP (2017) Journal of Composites for Construction, 21 (1). , p. 04016059; Khelifa, M., Celzard, A., Numerical Analysis of Flexural Strengthening of Timber Beams Reinforced with CFRP Strips (2014) Composite Structures, 111, pp. 393-400; Jasieńko, J., Nowak, T.P., Solid Timber Beams Strengthened with Steel Plates–Experimental Studies (2014) Construction and Building Materials, 63, pp. 81-88; Nadir, Y., Nagarajan, P., Ameen, M., Flexural Stiffness and Strength Enhancement of Horizontally Glued Laminated Wood Beams with GFRP and CFRP Composite Sheets (2016) Construction and Building Materials, 112, pp. 547-555; Zhang, J., Xu, Q.F., Xu, Y.X., Zhang, M., Research on Residual Bending Capacities of Used Wood Members Based on the Correlation between Non-destructive Testing Results and the Mechanical Properties of Wood (2015) Journal of Zhejiang University Science A, 16 (7), pp. 541-550; Heiduschke, A., Haller, P., Fiber-reinforced Plastic-confined Wood Profiles under Axial Compression (2010) Structural Engineering International, 20 (3), pp. 246-253; Biscaia, H.C., Cruz, D., Chastre, C., Analysis of the Debonding Process of CFRP-to-Timber Interfaces (2016) Construction and Building Materials, 113, pp. 96-112; Fernando, D., Frangi, A., Kobel, P., Behaviour of Basalt Fibre Reinforced Polymer Strengthened Timber Laminates under Tensile Loading (2016) Engineering Structures, 117, pp. 437-456; (2011), The Math Works, Inc., Natick, MA; (2011), Swanson Analysis Systems, Houston, PA; Dinwoodie, J.M., (2000) Timber: Its Nature and Behaviour, , 2nd edition, London, E & FN Spon; Hasnat, A., Islam, M.M., Amin, A.F.M.S., Enhancing the Debonding Strain Limit for CFRP-strengthened RC Beams Using U-Clamps: Identification of Design Parameters (2015) Journal of Composites for Construction, 20 (1). , p. 04015039","Islam, M.M.; Department of Civil Engineering, Bangladesh; email: mashfiq7777@gmail.com",,,"SAGE Publications Ltd",,,,,03611981,,TRRED,,"English","Transp Res Rec",Article,"Article in Press","",Scopus,2-s2.0-85067837565

In particular, duplex grades, with a balanced austenite ferrite microstructure, show greater proof strength and ductility than that of standard austenitic stainless steel groups. Over the last decade, those grades were often used in bridges in corrosive environments. The increased interest in stainless steel is also due to recent research demonstrating the good fatigue resistance of duplex welded components, raising an even higher interest in bridges made of these grades. The EN 1.4162 and 1.4062 duplex grades are characterized by a lower Nickel and Molybdenum content which results in a more stable cost, but at the same time more prone to pitting corrosion. In mildly corrosive environments, they can be a good alternative to protected carbon steel (regarding maintenance) or austenitic grades (regarding initial price). Additionally, reference research today exists proving that those grades have comparable corrosion resistance to the austenitic stainless steel grades EN 1.4307 and EN 1.4404. The ultimate objective of this study is to calculate the possible weight reduction in an existing carbon steel girder bridge, when lean duplex welded components are used. The benefit from the greater mechanical properties of the latter are considered according to the latest version of EN 1993-1-4 (2015). The fatigue design is made using the hot-spot stress method combined with finite element models to assess the local stress distribution, considering eight critical details along the girder. The fatigue life of all the considered details were found to be satisfactory with a higher number of loading cycles than the design value proposed by EN 1993-1-9 (2005). Conclusions were also drawn upon the influencing finite element parameters on the evaluation of hot spot stress via sensitivity analysis.

Appling a compressive force of 350N on Z direction, quite normal for mastication, was analyzed the behavior of the dental bridge. Zirconia, although having a high mechanical strength, is fragile when rotation or bending movements occur. The analysis reveals some bridge deficiencies, which may be due either to inaccuracies in the prosthetic abutment construction (especially in relation to their inclination), to the technique of realization or to insufficient dental support. In our study, the most vulnerable elements are the crowns on teeth 2.4 and 2.7. Finite element analysis, highlighting possible structural and design deficiencies, may be a solution to improve dental bridges. The only disadvantage of the finite element analysis that was performed before the actual restoration is related to the fact that performing the simulations involves a time-consuming phase. © 2019 SYSCOM 18 S.R.L.

The shear lag effect (SLE), an essential aspect of T-WBG which governs the stress and the deformation, is rather necessary to be revealed properly. The extraordinary issue of T-WBG analysis nowadays is the SLE impact on its dynamical response to external load. This paper proposes an improved finite element method (FEM) to obtain the realistic vibration characteristics of the T-WBG considering the SLE by theory analysis and formula derivation. Firstly, based on the classical plate and shell theory as well as beam theory, the T-WBG was divided into shell subunit for the roof and beam subunit for web and floor, respectively. Secondly, a 3-order polynomial which is consistent with the experiment results was adopted as the axial-displacement interpolation function of the roof subunit, whose nodal displacements parameters were also taken as the basic. Thirdly, the nodal displacement parameters of the web subunit and floor subunit were deduced by the basic according to the principle of deflection consistency. It is shown through a numerical example that the proposed method is much more economical to achieve reasonable accuracy than traditional FEM analysis software when dealing with the free vibration problem of the T-WBG considering the SLE. Besides, it is also observed that the natural frequency values considering the SLE have a trend of decreasing markedly in general, and the influence of SLE on higher-order frequency is more significant than on the lower one under the boundary condition of cantilever supported, while a contrary effect under the boundary condition of simple supported. © 2019 Zuolong Luo et al.",,,,,,,"Key Laboratory of Highway Construction and Maintenance Technology in the Loess Region of Shanxi Transportation Research Institute: KLTLR-Y12-9","*is work was supported by the Open Fund of Key Lab of Highway Construction and Maintenance Technology in Loess Region of Shanxi Transportation Research Institute (KLTLR-Y12-9). *is support is appreciated.",,,,,,,,,,"Visnjic, G., Nozak, D., Kosel, F., Kosel, T., Shear-lag influence on maximum specific bending stiffness and strength of composite I-beam wing spar (2011) Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, 225 (G5), pp. 501-511;

By using finite element analysis (FEA), stress and strain could be plotted in (a) graphs to produce stress-strain relationship. Based on the deflection formula, result from the FEA was compared with the calculation and the percentage of error was determined. Besides that, the comparison between the deflection behaviour of precast SBG with a variety of transversal slope or (so-called) crossfall gradient is also discussed in this chapter. A single span of precast SBG bridge model with constant span length, depth, thickness of top and bottom flange, width of top and bottom flange, thickness of web and few variables are tested for comparison of results.

This assumption is only true if the connections allow the rotation between elements, which in reality is not the case. There are always certain forces transmitted depending on the stiffness of the connection. The following work is intended to determine the rotational stiffness in the connections of a historical steel railway bridge. Different configurations of connections are modeled using component based finite element method (CBFEM) to obtain the real value of the stiffness in the joints. As a result of this analysis, a linear correlation between the value of the rotational stiffness and the number of rivets in the connections is observed. Similarly, there is a linear correlation with the stiffness of the element that is connected in the joint. These results can help to provide an estimate of the rotational stiffness to be considered in a more realistic approach for the assessment of historical railway bridges. © 2019, RILEM.","Bridge; Connections; Rotational stiffness; Steel",,,,,,"European Commission, EC","Acknowledgments.

An 8/6 pole 4 phase SRM configuration, is favored because of low cost, elementary mass production suitability, and robust design. The magnetic circuit is analyzed for an unaligned and aligned positions, which helps to determine the unaligned and aligned inductances. Further, the geometrical and electrical dimensions are used to analyze the motor's electrical and magnetic performance by FEA. The results obtained from the FE analysis are quite close to the analytic value. The motor is operated under certain (aligned, unaligned and intermediate positions with different excitations) conditions to obtain the motor magnetization and performance characteristics. Moreover, the fluxes at different positions with different excitations is obtained from the FE analysis and is used to build a MATLAB/Simulink model. The designed ceiling fan motor's performance using an asymmetric bridge converter is simulated and analyzed for satisfactory operation for fan application. © 2020 IEEE.","Ceiling Fan; Finite element analysis (FEA); Magnetic Circuit; Outer rotor; Switched Reluctance Motor","Finite element method; Magnetic circuits; MATLAB; Power electronics; Reluctance motors; Asymmetric bridge converters; Magnetic performance; Mass production; Matlab/Simulink modeling; Performance characteristics; Robust designs; Simulation-based modeling; Switched Reluctance Motor; Electric machine theory",,,,,,,,,,,,,,,,"http://www.indianfan.org/about_IFMA.html; Humphries, M., Rare earth elements: The global supply chain (2013) Congressional Research Service, Library of Congress, , Washington, DC, CRS Report for Congress; Krishnan, R., (2001) Switch Reluctance Motor Drives: Modelling, Simulation, Analysis, Design and Applications, , New York: CRC Press; Miller, T.J.E., (1993) Switched Reluctance Motors and Their Control.

Hearing aids are used as representative hearing rehabilitation devices. Bone conduction hearing aids are recommended for problems in the eardrum and middle ear. Bone conduction is classified according to the driving method into two types, electromagnetic and piezoelectric. Electromagnetic bone conduction causes skin disease and aesthetic problems due to transplantation, high power consumption, and external interference. Piezoelectric bone conduction converts electrical energy into mechanical vibrations, and the characteristics change linearly with size. However, the driving force of ear canal insertion of the piezoelectric body is limited because of the ear canal anatomy. In this paper, a piezoelectric actuator with a bridge structure inserted into the ear canal is proposed. The proposed method is that the displacement amplification ratio was derived using the formula of a bridge-type structure, and the displacement and resonance frequency were derived by finite element analysis (FEA) using different variables. The piezoelectric actuator was fabricated on the basis of FEA simulation results and verified through an artificial mastoid for stimulation in the ear canal. It is expected that the proposed piezoelectric actuator can be used in the various fields for sound and precision control. © 2020 The Author(s).","Actuator; bone conduction; displacement; finite element analysis; piezoelectric; resonance frequency","Audition; Hearing aids; Piezoelectricity; Vibrations (mechanical); Bridge structures; Displacement amplification; Electrical energy; External interference; High power consumption; Precision control; Rehabilitation devices; Resonance frequencies; Piezoelectric actuators",,,,,"HI18C1892; Ministry of Science, ICT and Future Planning, MSIP: NRF-2017M3A9E2065284, NRF-2018R1A2B2001434, NRF-2019R1C1C1009013; Korea Health Industry Development Institute, KHIDI; National Research Foundation of Korea, NRF","This study was supported by the National Research Foundation of Korea (NRF) grant funded by the Korean Government (MSIP) (Nos.

The structure forms a vital regional link together with the adjacent Brynglas tunnel and River Usk Bridge. A particular feature of the structure is the inclusion of half-joints which are hidden critical elements. The structure was suffering from early signs of structural deterioration as a result of chloride contamination. This paper offers an overall review of the rehabilitation programme, from condition inspection, to structural assessment and finally concrete repairs and corrosion protection. The structural assessment utilised non-linear finite element methods and aimed at firstly assessing the current load carrying capacity of the viaduct and secondly develop a detailed concrete repair sequence which negated the requirement of extensive temporary supports while maintaining full traffic and load carrying capacity on the M4. The rehabilitation strategy incorporated the design and installation of an innovative hybrid corrosion protection electrochemical system to extend the service life of the hidden critical elements by 30 years. The system is the first of its kind in half-joints and offers targeted corrosion protection that passivates the reinforcement from residual chloride contamination and the simplicity and low maintenance of galvanic anodes. © 2020 ICE Publishing: All rights reserved.",,"Bridges; Cathodic protection; Chlorine compounds; Concrete construction; Deterioration; Galvanic corrosion; Load limits; Loads (forces); Reinforced concrete; Chloride contamination; Electrochemical systems; Nonlinear finite element method; Rehabilitation strategy; Structural assessments; Structural deterioration; Structural rehabilitation; Temporary support; Repair",,,,,,,,,,,,,,,,"Andrade, C., Alonso, C., Test methods for on-site corrosion rate measurement of steel reinforcement in concrete by means of the polarization resistance method (2004) Materials and Structures, 37 (273), pp. 623-643; Angst, U.M., A critical review of the science and engineering of cathodic protection of steel in soil and concrete (2019) Corrosion Journal, 75 (12), pp. 1420-1433; (2009), ASTM, C876-09: Standard test method for corrosion potentials of uncoated reinforcing steel in concrete.

Notably, HSB460, which has a minimum yield strength of 460 MPa, does not exhibit a yield plateau beyond yielding and exhibits strain hardening. Such characteristics could provide advantages by absorbing the greater strain energy of steel members and increasing the local buckling strength, which may help develop more economic bridge designs. However, the current KDS for compression members of steel tubular columns was established based on the results of axial load tests for conventional structural steel having yield strengths from 250 to 350 MPa, which exhibits a yield plateau. Three-dimensional finite element analyses adopting actual stress-strain curve of HSB460 were subsequently carried out to evaluate the buckling strength, by considering the ovality, welding residual stresses, and the cross-section sizes. It was confirmed that HSB460 steel tubular columns could have larger margins compared to the current KDS, primarily due to advantages from strain hardening with no yield plateau. As such, with regards to local buckling, the proposed design guidelines for HSB460 steel is expected to enable a more economic bridge design. © 2020, Korean Society of Steel Construction.","finite element analysis; HSB steel; local buckling strength; slenderness; Steel tubular column","Buckling; Building materials; Load testing; Strain energy; Strain hardening; Stress-strain curves; Yield stress; Buckling strength; Compression member; Design standard; High performance steel; Structural steels; Three dimensional finite element analysis; Tubular columns; Welding residual stress; Steel bridges",,,,,"Ministry of Land, Infrastructure and Transport, MOLIT; Institute of Construction and Environmental Engineering, Seoul National University, ICEE, SNU","This research was partially supported by a Grant (20SCIP-B128568-04) from the Smart Civil Infrastructure Research Program funded by the Ministry of Land, Infrastructure and Transportation of the Korean Government via the Institute of Construction and Environmental Engineering at Seoul National University.",,,,,,,,,,"(2008) AISI D100-08 The cold-formed steel design manual, , American Iron and Steel Institute, Washington, DC; (2016) ANSI/AISC 360 – 16: Specification for structural steel buildings, , American Institute of Steel Construction, Chicago; (2014) ASTM Standard A370-14: Standard test methods and definitions for mechanical testing of steel products, , ASTM International, West Conshohocken; (2018) ASTM Standard A572/A572M-18: Standard specification for high-strength low-alloy columbium-vanadium structural steel, , ASTM International, West Conshohocken; (2012) Eurocode 3: Design of Steel Structures - Part 1–1: General Rules and Rules for Buildings; Chen, W.F., Ross, D.A., Tests of fabricated tubular columns (1978) Fritz Laboratory Reports.

The authorities of the bridge (Railways of the Slovak Republic and National Motorway Company) cannot afford to close it. In the case of closure, traffic in Bratislava would be paralyzed, as up to 100,000 vehicles pass the bridge daily. Because of that, only dynamic tests during operation are possible, but the mentioned companies do not possess a sophisticated measurement system for structural health monitoring purposes. Therefore, a preliminary proposal of a measuring system has been prepared, in accordance with the fact that the bridge is one of the most complex structures in Slovakia. An initial and subsequent validated and verified FEM model have been used for numerical calculations. Time history analysis has also been used for verification and validation of the FEM model.

The seal is 13.2 m long, 5.9 m wide, and 6.8 m deep and thus is considered mass concrete. The concrete mixture contains a 45% cement replacement with Class F fly ash. The seal is evaluated to identify the causes of cracking. The heat of hydration (HoH) and temperature rise are experimentally evaluated. Subsequently, a finite-element analysis model is developed using input from the experimental study. The modeling approach is validated with results from sizeable specimens. A coupled thermal-structural analysis is performed to evaluate the temperature-Time history and extent of cracking. The results indicate internal temperature in the seal slightly exceeds the allowable temperature of 70°C, which is known for exposing concrete to the risk of delayed ettringite formation. The gradient temperature exceeds the allowable limit of 19.4°C, leading to increased tensile strain. A sensitivity analysis indicates that two mixtures that contain a 70% cement replacement with slag, metakaolin, and/or fly ash are recommended for reducing the internal temperature below 70°C. However, it is concluded that the differential temperature requirement (19.4°C) cannot be met by altering material designs alone. Therefore, active cooling is necessary to control temperature when placing underwater seal structures with a volume-To-surface-Area ratio greater than 4.0. © 2020 American Society of Civil Engineers.","Bridge seal; Coupled analysis; Crack; Finite-element analysis; Mass concrete structure; Numerical; Strain; Temperature; Thermal; Validation","Bridges; Cements; Concrete mixtures; Fly ash; Holmium compounds; Hydration; Mixtures; Seals; Sensitivity analysis; Slags; Tensile strain; Cement replacement; Control temperatures; Coupled thermal-structural; Delayed ettringite formation; Finite element analysis model; Internal temperature; Underwater inspections; Volume-to-surface-area ratio; Structural design",,,,,,,,,,,,,,,,"(1997) Mass Concrete, , ACI (American Concrete Institute).

The emphasis is on evaluating the effect of the passive earth pressure for gravity-type anchorages under pullout loading. Three-dimensional FE analyses were performed for different types of bedrock and embedded depths. Based on this study, it is found that the displacement of the gravity-type anchorage decreased with increasing embedded depth due to the increase in the passive resistance in front of the anchorage. It is also found that the resistance due to passive earth pressure in front of the anchorage accounts for approximately 10–30% of the total resistance and thus represents a significant improvement in the prediction of the realistic resistance for gravity-type anchorages subjected to pullout loads. © 2020, The Author(s).","Embedded depth; Finite element analysis; Gravity-type anchorage; Passive earth pressure; Suspension bridge",,,,,,"Ministry of Land, Infrastructure and Transport, MOLIT","This research was supported by a Grant (20SCIP-B119947-05) from Construction Technology Research Program funded by Ministry of Land, Infrastructure and Transport of Korean government.",,,,,,,,,,"(2014) ABAQUS/Explict Version 6.14, , Dassault Systemes, Providence; Adanur, S., Gunaydin, M., Altunisik, A.C., Sevim, B., Construction stage analysis of Humber suspension bridge (2012) Appl Math Model, 36, pp. 5492-5505; Acharyya, R., Finite element investigation and ANN-based prediction of the bearing capacity of strip footings resting on sloping ground (2019) Int J Geo-Eng, 10 (1), pp. 1-19; Day, R.A., Potts, D.M., Modelling sheet pile retaining walls (1993) Comput Geotech, 15 (3), pp. 125-143; Han, Y., Liu, X., Wei, N., Li, D., Deng, Z., Wu, X., Liu, D., A comprehensive review of the mechanical behavior of suspension bridge tunnel-type anchorage (2019) Adv Mater Sci Eng, 2019, pp. 1-9; Hoek, E., Brown, E.T., Practical estimates of rock mass strength (1997) Int J Rock Mech Mining Sci, 34 (8), pp. 1165-1186; Jeong, S.S., Seo, D.H., Analysis of tieback walls using proposed p–y curves for coupled soil springs (2004) Comput Geotech, 31 (6), pp. 443-456; Li, J.P., Li, Y.S., Ground modification and seismic mitigation (2006) ASCE, GSP, 152, pp. 207-214; Naseer, S., Sarfraz Faiz, M., Iqbal, S., Jamil, S.M., Laboratory and numerical based analysis of floating sand columns in clayey soil (2019) Int J Geo-Eng, 10 (1), pp. 1-16; ","Chung, M.; Korea Institute of Civil Engineering and Building Technology, 283 Goyang-daero, Ilsanseo-gu, South Korea; email: mkchung@kict.re.kr",,,"Springer",,,,,20929196,,,,"English","Intl.

The bridge is modeled by using ANSYS 15.0 program with solid and shell elements to represent concrete and steel members, respectively. AASHTO HL-93 truck is idealized as 3D non-linear model consisting of five lumped masses connected by rigid beams and supported by spring-dampers. The separation between the tires and road surface and surface roughness condition are simulated by Gap and actuator elements, respectively. The road surface roughness profiles are generated from power spectral density (PSD) and cross spectral functions. The models used are capable to take all bridge and vehicle responses into consideration with no limitations on the complexity of the models. The dynamic responses of the multi I-girder bridge are investigated under conditions of various loading positions, roughness classes, vehicle speeds, and bump height. The dynamic behaviors are presented in terms of Dynamic Amplification Factors (DAF). The results show the girder that itself supporting the moving vehicle has lower value of DAF because of higher static responses. A 45 km/hr vehicle speed provides higher DAF value. The bump heights have significant effect on DAFs for bridge with short span. © Published under licence by IOP Publishing Ltd.",,,,,,,,,,,,,,,,,,"Yang, Y.B., Liao, S.S., Lin, B.

Three different Sille stone types that were used in various parts of the bridge were defined petrographically, despite their similar look from the outside. Samples were obtained from regional stone quarries with similar characteristics with these defined stones. Geochemical, physical, and mechanical tests were conducted on these samples. In addition to these tests, a group of samples were subjected to freeze-thaw cycles, and their mechanical features were defined after freeze-thaw. A numerical model of the bridge was built using the characteristic of the obtained material, and the structural situation before and after the freeze-thaw was analyzed on this model under the current loads. The results indicated that stress distributed normally over the bridge under current loads before freeze-thaw, displaced more compared to the other model while the displacement level remained limited after conducting freeze-thaw, losing its bearing capacity very soon. On the other hand, the stresses distribution on the bridge was spread over the entire surface before freeze-thaw while they were concentrated in a local area after freeze-thaw. Furthermore, the maximum compressive strain values of stones used in the bridge were determined and it was observed that the values were larger than the result obtained from before the freeze-thaw model. In particular, the landscape work carried out in recent years caused water to be retained underneath the bridge. Due to this, freeze-thaw is expected to intensify around the bridge piers, which leads us to assess the necessity to build the bridge using Sille stones with high mechanical durability. © 2020 Elsevier Ltd","Bridge; Damage; Failure; Finite element analysis; Freeze-thaw; Sille stone","Finite element method; Thawing; Central anatolia; Current situation; Finite elements analysis; Freeze-thaw cycles; Maximum compressive strain; Mechanical durability; Mechanical feature; Stresses distribution; Freezing",,,,,,"This study has been drawn from the master’s degree thesis of Murat SAYDAN, and supported by the Project No.2013 – ÖYP – 080 of the Turkish Council of Higher Education Lecturer Trainee Program.",,,,,,,,,,"Cessford, C., A new dating sequence for Catalhoyuk (Anatolia) (2001) Antiquity, 75 (290), pp. 717-725. , (in English); Orton, D., A tale of two tells: dating the Çatalhöyük West Mound (2018) Antiquity, 92 (363), pp. 620-639; Eyice, S., Konya ile Sille Arasında Akmanastır (1966) Şarkiyat Mecmuası, 6, pp. 135-160; Keller, J., Burgath, K., Jung, D., Wolff, F., Geologie und Petrologie des neogenen Kalkalkali-Vulkanismus von Konya (Erenler Dag-Alaca Dag-Massiv, Zentral-Anatolien) (1977) Schweizerbart'sche Verlagsbuchhandlung; Besang, C., FJ, E., (1977), Radiometrische-Altersbestimmungen an Neogenen Eruptivgesteinen der Tuerkei; Gençoğlu Korkmaz, G., Asan, K., Kurt, H., Morgan, G., 40 Ar/ 39 Ar geochronology, elemental and Sr-Nd-Pb isotope geochemistry of the Neogene bimodal volcanism in the Yükselen area, NW Konya (Central Anatolia, Turkey) (2017) J.

Corrosion has been believed to be one of the main reasons for reducing the load carrying capacity and the service life of structural steel, especially for the structures in harsh service environments. To mitigate corrosion for structural steel, coatings have been widely applied. On the other hand, to monitor corrosion in real time, embedding fiber Bragg grating (FBG) inside the coatings becomes a potential solution for coated steel structures. However, due to the fact that FBG sensors are local point sensors, the localization of pitted corrosion based on these sensors is very challenging. In this study, a methodology based on a three-sensor network was set up to detect the location and severity of the pitted corrosion on steel structures in two dimension (2D). The 2D simply supported plate theory together with the numerical simulation based on finite element analysis (ANSYS software) was used to derive the transfer function of the pitted corrosion location to the FBG sensor reading. Depending on the parametric study through numerical analysis, a pitted corrosion location exhaustion algorithm was successfully programmed. To verify the feasibility of this algorithm, laboratory experiments were carried out using a steel pipe with three FBG sensors and a temperature compensation sensor embedded inside a layer of epoxy coating (Duralco 4461). The experimental results indicated that the proposed methodology has potential to locate and assess the pitted corrosion on steel structures. © 2020, Springer-Verlag GmbH Germany, part of Springer Nature.","Algorithm;

A typical 7.94-mm thick deep corrugated structural plate can normally span up to 19.8 m for typical bridge design loads. In order to achieve longer spans, it is necessary to increase the flexural stiffness of the plate. The new strengthening system consists of wide flange beams connected to the corrugated structural plate using rigid brackets. Several tests were conducted at the University of Cincinnati Large Scale Testing Facility to evaluate the behavior and stiffness of the beam-plate system. Tests were carried out using a number of different reinforcing beam sizes and bracket spacings. Equations for determining the cross-sectional properties and capacity of the stiffened system were developed. Design case studies were conducted using a special finite element program called CANDE (Culvert ANalysis and DEsign). Different plate gauges in combination with a number of wide flange beams were used in the finite element analyses. The efficiency of the strengthened system was evaluated. In this paper, recommendations are made for design and analysis of strengthened long-span buried bridges, i.e., culverts. This study has found that it is possible to design lighter, longer, and more cost-effective structures through the use of stiffened plates. © 2020 American Society of Civil Engineers.",,"Bridges; Cost effectiveness; Culverts; Finite element method; Flanges; Stiffness; Analytical evaluation; Beam-plate systems; Design and analysis; Design case studies; Flexural stiffness; Large scale testing; Special finite elements; Strengthening systems; Plates (structural components)",,,,,,,,,,,,,,,,"(2000) Classification of Soil and Soil-aggregate Mixtures for Highway Construction Purposes, 91, pp. 1-4. , AASHTO, Washington, DC: AASHTO; Abdel-Sayed, G., Bakht, B., Jaeger, L.G., (1993) Soil-steel Bridges: Design and Construction, , New York: McGraw-Hill; (2016) AISC Specification for Structural Steel Buildings, , AISC.

Further, in an FRM, the Permanent Magnets (PMs) are placed on the stator, and hence the magnets are not subjected to centrifugal forces. However, the major drawbacks of FRM are low power factor, voltage regulation and significant leakage flux. In this paper, a novel ring outer rotor FRM with Inner Bridge (IB) is proposed to address these limitations for a direct-drive roof-top wind generator. A Magnetic Equivalent Circuit (MEC) has been developed for a ring FRM to account for the leakage flux. Further, the proposed FRM is compared with a conventional 6/14 outer rotor FRM using 2-D Finite Element (FE) analysis and the results are presented. © 2020 IEEE.","Finite Element Analysis; Flux Reversal Machine (FRM); Permanent Magnets; Reluctance Machines","Equivalent circuits; Fault tolerance; Industrial electronics; Magnetic leakage; Permanent magnets; Roofs; Voltage regulators; Aircraft generators; Centrifugal Forces; Fault-tolerance capability; Flux-reversal machines; High power density; Magnetic equivalent circuits; Permanent magnets (PMs); Wind generator systems; Electric generators",,,,,,,,,,,,,,,,"Sharma, A., Sashidhar, S., Comparison of wind turbine generators for roof-Top wind power: Case study, issues and challenges (2019) Proc. 39th Annual IEEE Region 10 Tencon Conf, pp. 592-597. , Kochi, India; Deodhar, R.P., Andersson, S., Boldea, I., Miller, T.J.E., The flux-reversal machine: A new brushless doubly-salient permanent-magnet machine (1997) IEEE Trans.

The analysis is specifically interesting in the case of variable magnetic components. In general, the core temperature varies as a function of several parameters, such as the ambient temperature, the excitation current applied to the inductor windings -which causes core and winding losses and results in heating of the magnetic material- and finally the thermal conductivity of the magnetic material. To decouple the different factors affecting the inductance, Finite Element Analysis simulations are carried out for a variable inductor as a case study. Reinforced by this analysis, a final lookup table/map is proposed to accurately scale the inductance variation range predicted by the analytical design methods in order to match the practical measurements under different excitation currents. © 2020 IEEE.","design; FEA; temperature effect; variable magnetics","Electric windings; Energy conversion; Inductance; Magnetic devices; Magnetic materials; Magnetism; Power converters; Table lookup; Temperature; Winding; Analytical design method; Excitation currents; Inductance computation; Inductance variation; Magnetic components; Operating temperature; Operation conditions; Power electronic converters; Thermal conductivity",,,,,"864459, UE-19-TALENT-864459; ENE2016-77919, PID2019-111051RB-100; Gobierno del Principado de Asturias: BP16-133, FC-GRUPIN-IDI/2018/000241, UID/EEA/50008/2019","The present work has been partially supported by the European Union's H2020 Research and Innovation programme under Grant Agreement No. 864459 (UE-19-TALENT-864459).

The low weight / capacity characteristics of composite materials make it possible to accommodate much more loads. Because of the great importance of the floating bridges for both military and civilian purposes especially in crises, the evolution of floating bridges is necessary. The traditional transportation steel ferry is composed of floating steel pontoons to accommodate the MLC-70 (Tank load) of weight equals (63.5 t). In this study, the steel floating pontoon is replaced with composite pontoon simulated for both carbon fibres polymers and glass fibres polymers with the laminate configuration. The finite element analysis is performed using ANSYS software. The capacity of the ferry is increased to reach (90 t) instead of (70 t). The total deformation is determined under the applied load. The failure criteria is investigated for both composite models (Tsai-Wu, Tsai-Hill, maximum stress and maximum strain). The nonlinear buckling analysis is also, investigated. The optimization process is designed and performed to get the optimum number of layers and angles orientation of the composite layers as well as possible. © Published under licence by IOP Publishing Ltd.",,,,,,,,,,,,,,,,,,"Vinson, J R, (1993) The Behavior of Shells Composed of Isotropic and Composite Materials ed, , (Springer);

Orabona, St., Bari, Italy","– This paper reports the design of a patch antenna that uses of graphene-based shorting elements to implement advanced functionalities, such as multi-band and beam-steering, which make it extremely attractive for the future Fifth-Generation (5G) wireless networks. The proposed structure has 36.75×29.25 mm2 size and it has been designed on a Rogers RT/duroid 5880 substrate, 1.58 mm thick. It is composed by an external slotted rectangular patch that contains an internal circular shape. The internal shape is separated from the external one by a circular slot but it is linked to it by four copper bridges short-circuited to the underlying ground plane through a thin metal pin, one for each bridge. It has been shown that the multi-band and the beam-steering functionalities are strongly affected by the geometric location of the shorting pins. By controlling the connection of the bridges perpendicular to the antenna length, the direction of the antenna main lobe can be changed. By using the Finite Element Method (FEM), the geometric location of the shorting pins has been optimized so that the antenna resonates at 3.5 GHz frequency, exhibiting a 6.6 dBi maximum gain and a-17.55 dB S11 parameter. Moreover, by controlling electronically the connection of the shorting elements using graphene foils, three distinct beams, steering between-22 to +22 degrees, have been obtained. The beams show about 1.4 dBi theoretical antenna gain using graphene foils with 20 Ω/sq sheet resistance. Copyright ©. © 2020 The Authors.

In CFT columns, the bearing capacity of columns is inversely related to buckling, therefore, buckling is of particular importance at these sections, the AISC Code uses effective bending rigidity (EIeffective) to calculate the critical buckling load in concrete filled steel columns, to apply the effect of reducing concrete confinement, the AISC code provides a maximum value of 0.9 of the reduced concrete confinement coefficient for the equation. Effective bending rigidity (EIeffective), this relationship is provided in AISC code for circular and square sections, therefore, the effect of the column shape geometry on the core concrete confinement is very influential and changes the effective bending rigidity (EIeffective) of the section. The AISC code does not provide a coefficient to consider the type of cross-sectional geometry in CFT columns, therefore, in this study, three groups experimental, numerical (FEM) and theoretical were used to provide critical buckling load correction, finally, it was concluded that the critical buckling load for the cross-section (L) shape due to the lower confinement of the concrete core is 20.07% lower than the AISC code equation, also with a 67% increase in slenderness ratio, the critical buckling load decreased by 14.52%. © 2020, Korean Society of Steel Construction.","Composite column;

Many specifications adopt the theory of elastic stability as a means to obtain the critical buckling force of the upper chord. In these specifications, the axial force in the upper chord is simplified to parabolic or equivalent force distribution in the span. However, the calculation results of these simplified models can not always satisfy calculation precision in practical projects. To obtain a critical buckling load of the upper chord, using energy method, a mechanical model with trapezoidal axial force distribution is put forward to establish an elastic theoretical model with higher precision. Three bridges with different span are analyzed and theoretical results are in good agreement with buckling analysis by use of finite element method. The trapezoidal axial force distribution model has higher precision than equivalent and parabolic axial force distribution models used in the current specifications. Meanwhile, the effective length coefficient of the upper chord is derived by use of Euler's Formula, and a simplified table based on TAFDM is presented to obtain aluminum half-wave number and the effective length coefficient of the upper chord. © 2020 Institution of Structural Engineers","Buckling load; Compression member; Elastic; Energy method; Half-through truss bridge",,,,,,"Fundamental Research Funds for the Central Universities: 2012QNB28","The authors wish to express their gratitude and sincere appreciation to Fundamental Research Funds for the Central Universities ( 2012QNB28 ) for financing this research work.",,,,,,,,,,"Wen, Q., Qi, Y., Research on design of aluminum truss bridge (2010) Adv Mater Res, 168-170, pp. 1776-1779; Wang, T.L., Impact in railway truss bridge (1993) Comput Struct, 49 (6), pp. 1045-1054; Birajdar Harshad Subhashrao, Maiti Pabitra Ranjan, and Singh Pramod Kumar, Strengthening of Garudchatti bridge after failure of Chauras bridge (2016) Eng Fail Anal, 62, pp. 49-57; Ruiqi, L., Xinzhe, Y., Wancheng, Y., Xinzhi, D., Guoyu, S., Seismic analysis of half-through steel truss arch bridge considering superstructure (2016) Struct Eng Mech, 59 (3), pp. 387-401; Liangmou, L., Guanyao, X., Testing study on the global stability of “321” prefabricated highway steel bridge (2007) Steel Constr, 4, pp. 59-61; Iwicki, P., Stability of trusses with linear elastic side-supports (2007) Thin-Walled Struct, 45 (10), pp. 849-854; Lee, S.L., Clough, R.W., Stability of pony truss bridges (1958) Bridge Struct Eng, 18, p. 91; Bleich, F., Buckling Strength of Metal Structures (1952), McGraw-Hill New York; Hu, L.S., The Instability of Top Chords of Pony Trusses, dissertation (1952), University of Michigan Ann Arbor, MI; Holt, E.C., (1952), Buckling of a Pony Truss Bridge, in Stability of Bridge Chords without Lateral Bracing, Rep.

These bridges are critical in shear when analyzed using EN 1992-1-1:2005; however, in reality, they show no significant signs of distress, possibly because of residual bearing (punching shear) capacity arising from compressive membrane action. Since these bridges are old, it is an astute approach to check whether they can be used for a few more decades, provided they are safe and reliable against modern traffic loads. The results could then be applied to a wider range of structures, especially in developing countries facing economic constraints. A prototype bridge was selected and experimental, numerical and theoretical approaches were used to investigate its bearing capacity. Respective coefficients of variation of 11% and 9% were obtained when the experimental and the finite element analysis punching loads were compared with the theoretical results. This led to the conclusion that the existing transversely prestressed concrete bridge decks still have sufficient bearing capacity and considerable cost savings can be made if compressive membrane action is considered in the analysis. © 2020 International Association for Bridge and Structural Engineering (IABSE).","bridge decks; compressive membrane action; nonlinear analysis; punching shear; transverse prestressing","Bearing capacity; Bridge decks; Concrete beams and girders; Concrete bridges; Developing countries; Nonlinear analysis; Coefficients of variations; Compressive membrane action; Economic constraints; Prototype bridges; Punching shear; Theoretical approach; Traffic loads; Transverse prestressing; Prestressed concrete",,,,,"University of Engineering and Technology, Lahore, UET; Ministerie van Infrastructuur en Milieu, IenM; Rijkswaterstaat, RWS","The authors wish to express their gratitude and sincere appreciation to Rijkswaterstaat, Ministry of Infrastructure and the Environment, The Netherlands, and the University of Engineering and Technology, Lahore, Pakistan, for financial contributions during the course of this research.",,,,,,,,,,"(2005) Eurocode 2—Design of Concrete Structures—Part 1-1: General Rules and Rules for Buildings, p. 229. , Comité Européen de Normalisation (CEN), Brussels, Belgium; (1995) Regulations for Concrete: Structural Requirements and Calculation Methods, , Dutch Normalisation Institute (NEN), (in Dutch).

A moving wheel/rail axis element that couples two wheels and rails together is first developed to generate a train finite element model with 12 cars, while the sliding, sticking, and separation modes of the wheels and rails are accurately simulated. The finite element results indicate that the base shear of the bridge with lead rubber bearings is much smaller than that without lead rubber bearings. Similar to the base shear, the train derailment coefficients for the bridge with lead rubber bearings are much smaller than those without lead rubber bearings because yield lead rubber bearings during large seismic loads can change the bridge natural frequency to avoid resonance. For earthquakes with a very long dominant period, the lead rubber bearing effect to reduce the train derailment may not be obvious because the natural period of the bridge due to the full yield of lead rubber bearings can approach the dominant period of the earthquake. © The Author(s) 2020.","Bridge;

Over the past ten to fifteen years, research efforts have been undertaken to improve understanding of storm surge effects on bridges and explore how best to mitigate these effects. This paper documents development and assessment of a finite element analysis framework named AMBUSH that calculates forces applied to bridges subjected to storm surge loading. AMBUSH was shown to be capable of calculating reaction forces for a Biloxi Bay Bridge span for 14 storm events representing 5 storm categories. Simulation results compared favorably to American Association of State Highway and Transportation Officials (AASHTO) Guide Specifications that were released relatively soon after Hurricane Katrina. Deviations of AMBUSH could be applied to other bridge or structural engineering problems with manageable reconfiguration. © 2020 American Society of Civil Engineers.",,"Bridges; Floods; Hurricane effects; Storms; Element analysis; Guide specifications; Hurricane katrina; Hurricane storm surge; Paper documents; Reaction forces; Research efforts; Structural engineering problems; Finite element method",,,,,"U.S. Department of Homeland Security, DHS","This paper investigates storm surge on existing coastal highway bridges with concrete girders and diaphragms supporting a concrete deck where cavities are formed due to girder and diaphragm intersection using finite element modeling following the Fig. 1 flow chart.

In this method, the scale gap between the geometrical information of motor cells in the small-scale and mechanical behaviors of the cellular structures at the macroscale is bridged through a multiscale framework named multiscale finite element method. The heterogeneous information of the microstructure is then equivalent to the macroscopic coarse elements through the multiscale base functions about the displacements for the solid matrix as well as the fluid pressure. Combined with the “element-independent” corotational algorithm, both the tangent stiffness matrix of the coarse grid elements and their nodal forces can be directly deduced, which will be utilized to decompose the geometrically nonlinear motions of equivalent coarse grid elements at the macroscale level. Consequently, the initial geometrically nonlinear behaviors of the 3D fluidic cellular structures could be simulated by the iteration procedures on the coarse-grid meshes, which will greatly reduce the computation time and memory cost. At the same time, the mechanical responses of the motor cells in the microscale could be easily computed from the obtained macroscopic solutions by the downscaling technique of the multiscale method. To verify the proposed nonlinear multiscale method, some numerical examples are presented. The results demonstrated that the developed nonlinear multiscale formulation for the 3D problems could provide high precision solutions as well as acceptable numerical efficiencies. © 2020, Springer Nature B.V.","3D planted inspired cellular structures; Extended multiscale finite element method; Geometrically nonlinear problems; Multiscale co-rotational technique","Cellular automata; Iterative methods; Nonlinear analysis; Numerical methods; Stiffness matrix; Cellular structure; Geometrical informations; Geometrically non-linear analysis; Geometrically nonlinear problem; Heterogeneous information; Multiscale co-rotational technique; Multiscale finite element method; Tangent stiffness matrix; Finite element method",,,,,"Dalian High-Level Talent Innovation Program: 2015R046; National Natural Science Foundation of China, NSFC: 11672062, 11772083, 11872133; Aeronautical Science Foundation of China: 2017ZA63003; Fundamental Research Funds for the Central Universities: DUT17LK26","The supports of this investigation by the National Natural Science Foundation of China (11772083, 11672062, 11872133), the Fundamental Research Funds for the Central Universities (DUT17LK26), Dalian High Level Talent Innovation Support Program (2015R046) and Aeronautical Science Foundation of China (2017ZA63003) are gratefully acknowledged.",,,,,,,,,,"Barrett, R., Barrett, C., Biomimetic FAA-certifiable, artificial muscle structures for commercial aircraft wings (2014) Smart Mater.

The purpose of this paper is to investigate a finite element methods approach for the inclusion of a simplified structural design method into floodway design procedures. Design/methodology/approach: This research uses a three-dimensional finite element method to investigate numerically the different parameters, geometric configurations and loading combinations which cause floodway vulnerability during extreme flood events. The worst-case loading scenario is then used as the basis for design from which several structural design charts are deduced. These charts enable design bending moments and shear forces to be extracted and the cross-sectional area of steel and concrete to be designed in accordance with the relevant design codes for strength, serviceability and durability. Findings: It was discovered that the analysed floodway structure is most vulnerable when impacted by a 4-tonne boulder, a 900 mm cut-off wall depth and with no downstream rock protection. Design charts were created, forming a simplified structural design process to strengthen the current hydraulic design approach provided in current floodway design guidelines. This developed procedure is demonstrated through application with an example floodway structural design. Originality/value: The deduced structural design process will ensure floodway structures have adequate structural resilience, aiding in reduced maintenance and periods of unserviceability in the wake of extreme flood events. © 2020, Emerald Publishing Limited.","Bridge failure; Floods; Floodways; Impact load; Infrastructure; Resilience","design flood; design method; extreme event; finite element method; loading; three-dimensional modeling; vulnerability",,,,,,"The authors would like to acknowledge the Lockyer Valley Regional Council for providing information relating to floodways and the support of the Commonwealth of Australia through the Cooperative Research Centre program; Bushfire and Natural Hazard CRC and the Research Training Program (RTP) Scholarship.

In order to accurately and effectively analyze the characteristics of low-frequency noise, a prediction model of vibration of box girder was established based on the hybrid FE-SEA method. When the train speed is 140 km/h, 200 km/h and 250 km/h, the vibration and noise of the box girder induced by the vertical wheel-rail interaction in the frequency range of 20-500 Hz are analyzed. Detailed analysis of the energy level, sound pressure contribution, modal analysis and vibration loss power of each slab at the operating speed of 140 km /h. The results show that: (1) When the train runs at a speed of 140km/h, the roof contributes more to the sound pressure at the far sound field point. Analyzing the frequency range from 20 to 500 Hz: The top plate plays a very important role in controlling sound pressure, contributing up to 70% of the sound pressure at peak frequencies. (2) When the train is traveling at various speeds, the maximum amplitude of structural vibration and noise generated by the viaduct occurs at 50 Hz. The vibration acceleration of the box beam at the far field point and near field point is mainly concentrated in the frequency range of 31.5-100 Hz, which is consistent with the dominant frequency band of wheel-rail force. Therefore, the main frequency of reducing the vibration and noise of the box beam is 31.5-100 Hz. (3) The vibration energy level and sound pressure level of the box bridge at different speeds are basically the same. The laws of vibration energy and sound pressure follow the rules below: web <wing plate <top plate. (4) When the train is running at a higher speed, the noise and vibration of the bridge structure are larger. (5) The hybrid FE-SEA method is used to predict the structural noise of the box beam, which not only improves the efficiency, but also improves the calculation accuracy, thereby expanding the frequency range of the structural noise and improving the prediction accuracy.

This oxide, unlike rust, has the same specific volume of the pure metal. This characteristic allows overcoming the need of protecting treatments like galvanization, etc. While its properties promote its exploitation in civil applications, there are also some examples of application where safety is a fundamental requirement. In the northern part of Italy, Cor-Ten is used for safety barriers (guard rails) along the highways. It is, therefore, fundamental to know the ductile behavior of this material, for which few data are available in literature. Quasi-static experimental tensile tests have been performed on eight samples having different shapes. Numerical simulations carried out with an open-source code (Code_Aster) reproduced the experimental setup. In this way, it was possible to calculate the stress state and the plastic strain at failure needed for the calibration of the ductile damage model. The material model is based on classical incremental plastic response with isotropic hardening and phenomenological concept of damage. © 2020 WIT Press.","Code_Aster; Cor-Ten; Ductile fracture; Experiments; FEM; Fracture locus",,,,,,,"ACKNOWLEDGEMENT The authors would like to thank AERRE [35] for the financial support.",,,,,,,,,,"Decker, P., To coat or not to coat?

In this type of generator which comprises one exciter as exciter and the main machine, rotating parts such as rectifier bridge, exciter armature, and their connections are more likely to defect. Therefore, considering the relevant literature, the exciter armature open-circuit fault is taken into account for the investigation. Consequently, the brushless generator model is developed for two states, including healthy and exciter armature open-phase fault under no-load condition. Then, an analytical approach is proposed for the terminal voltage harmonic analysis which is utilized for the two states. Thus, the harmonic spectrum can be achieved for these states. These harmonic components are compared for healthy and faulty states, and the major distinctive components are determined. Hence, the occurred exciter fault can be detected using these components. In order to evaluate the model and its efficiency, finite element analysis, and experimental results are utilized. © 2020 IEEE.","Brushless synchronous generator; Fault detection; Finite element analysis","Fault detection; Harmonic analysis; Spectrum analysis; Synchronous generators; Analytical approach; Brushless generators; Brushless synchronous generators; Harmonic components; Harmonic spectrum; No-load conditions; Open circuit faults; Terminal voltages; Electric machine theory",,,,,,,,,,,,,,,,"Salah, M., Bacha, K., Chaari, A., Benbouzid, M.E.H., Brushless three-phase synchronous generator under rotating diode failure conditions (2014) IEEE Transactions on Energy Conversion, 29 (3), pp. 594-601. , Sep; Mohammad-Alikhani, A., Rahnama, M., Vahedi, A., Neighbors class solidarity feature selection for fault diagnosis of brushless generator using thermal imaging (2020) IEEE Transactions on Instrumentation and Measurement, p. 1. , Feb; Wei, Z., Liu, W., Zhang, Z., Jiao, N., Peng, J., Meng, T., Rotating rectifier fault detection method of wound-rotor synchronous startergenerator with three-phase exciter (2018) The Journal of Engineering, 2018 (13), pp. 524-528. , Jan; Wu, Y., Cai, B., Ma, Q., An online diagnostic method for rotary diode open-circuit faults in brushless exciters (2018) IEEE Transactions on Energy Conversion, 33 (4), pp. 1677-1685. , Dec; Ahmadi, A., Mahbubi, S., Shahnazari, M., Rotating rectifier fault detection in brushless excitation system of synchronous generators (2019) ICEE 2019-27th Iranian Conference on Electrical Engineering, 2019, pp. 787-791. , January; Cui, J., Shi, G., Zhang, Z., Fault detection of aircraft generator rotating rectifier based on sae and svdd method (2017) 2017 Prognostics and System Health Management Conference (PHM-Harbin), pp. 1-5; Cui, J., Tang, J., Shi, G., Zhang, Z., Generator rotating rectifier fault detection method based on stacked auto-encoder (2017) 2017 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD), pp. 256-261; Liu, J., Gao, K., Liu, P., Design and application for fault monitoring circuit of rotating rectifier in aviation brushless ac generator (2015) 2014 IEEE Chinese Guidance, Navigation and Control Conference, CGNCC 2014; Sun, C., Liu, W., Wei, Z., Jiao, N., Pang, J., Open-circuit fault diagnosis of rotating rectifier by analyzing the exciter armature current (2020) IEEE Transactions on Power Electronics, 35 (6), pp. 6373-6385. , Jun; Pang, J., Liu, W., Wei, Z., Sun, C., Jiao, N., Han, X., Online diode fault detection in rotating rectifier of the brushless synchronous starter generator (2020) IEEE Transactions on Industrial Informatics; Rahnama, M., Vahedi, A., Alikhani, A.M., Takorabet, N., Diode open-circuit fault detection in rectifier bridge of the brushless synchronous generator (2018) 2018 XIII International Conference on Electrical Machines (ICEM); Rahnama, M., Vahedi, A., Application of acoustic signals for rectifier fault detection in brushless synchronous generator (2019) Archives of Acoustics, 44 (2), pp. 267-276. , Apr; Mohammad-Alikhani, A., Vahedi, A., Rahnama, M., Barzegari Bafghi, M.H., A wrapper-based feature selection approach for accurate fault detection of rotating diode rectifiers in brushless synchronous generators (2020) IOP Conference Series: Materials Science and Engineering, 671 (1); Rahnama, M., Vahedi, A., Alikhani, A.M., Montazeri, A., Machine-learning approach for fault detection in brushless synchronous generator using vibration signals (2019) IET Science, Measurement and Technology, 13 (6), pp. 852-861. , Apr; Li, X.Y., Malik, O.P., A microprocessor-based fault monitor for rotating rectifiers of brushless ac exciters using a pattern-recognition approach (1996) Electric Machines and Power Systems, 24 (2), pp. 189-198. , Mar; Zhang, C., Xia, L., A novel online diagnosis of brushless generator rotary rectifier fault (2008) Proceedings of the 11th International Conference on Electrical Machines and Systems, ICEMS 2008; Sottile, J., Trutt, F.C., Leedy, A.W., Condition monitoring of brushless three-phase synchronous generators with stator winding or rotor circuit deterioration (2006) IEEE Transactions on Industry Applications, 42 (5), pp. 1209-1215. , Sep",,,"IEEE Industrial Electronics Society (IES);The Institute of Electrical and Electronics Engineers (IEEE)","Institute of Electrical and Electronics Engineers Inc.","2020 International Conference on Electrical Machines, ICEM 2020","23 August 2020 through 26 August 2020",,165584,,9781728199450,,,"English","Proc. - Int.

Based on a theoretical approach to reduce the stress calculation time at the early design stage, inclined bridges and core edges are applied to reduce the stress of the bridges. The derived equations function as a guideline to design mechanically strong bridges, even when the shape of each pole is different. Stress analysis by FEM demonstrates the validity of the theoretical formula. Finally, the electrical characteristics of a conventional machine and our developed one, both of which had the same mechanical strength, are compared. The comparison clarifies that the no-load induced back EMF of our developed machine increases by 40%, and its copper loss under rated conditions decreased by 24% due to reduction of the magnetic flux leakage. © 2020 IEEE.","Asymmetric rotor; Bridge; Magnetic flux leakage; Permanent magnet machine","Bridges; Electric machinery; Magnetic leakage; Stress analysis; Conventional machines; Early design stages; Electrical characteristic; Magnetic flux leakage; Rotor structures; Stress calculations; Theoretical approach; Theoretical formula; Structural design",,,,,,,,,,,,,,,,"Lee, T.-G., Kim, D.-J., Hong, J.-P., Performance improvement by making holes of interior permanent magnet synchronous motor (2009) Proc.

Moreover, the mathematical model is established, the analysis of the torque coefficient and levitation coefficient is employed, then, the accuracy of the model is verified by finite element method. In order to eliminate the axial and radial levitation. average current control is implemented. Furthermore, the asymmetric half-bridge type is adopted as the power converter of the BSRM control.

This leads to some production problems such as difficult feeding and surface scratching in subsequent processes. Based on the principle of elastic mechanics, the mechanism of transverse bending in the process of uncoiling is studied and an analytical model is established. Then the relationship between transverse bending and influence factors, including the curvature radius of longitudinal bending, strip width and strip thickness, is obtained. The study indicates that the transverse bending is caused by longitudinal bending before uncoiling. And the strip width and the curvature radius of longitudinal bending have a great influence on the transverse bending but the strip thickness has little influence. The transverse bending diminishes nonlinearly with the increase of curvature radius of longitudinal bending and increases nonlinearly with the increase of strip width. © 2019 Institute of Materials, Minerals and Mining.","analytical model; elastic mechanics; finite element model; hot-rolled strip; longitudinal bending; temper mill; Transverse bending; uncoiling process","Analytical models; Finite element method; Hot rolling; Strip metal; Curvature radii; Elastic mechanics; Hot-rolled strip; Production problems; Quantitative study; Strip-widths; Temper mills; Transverse bending; Box girder bridges",,,,,"National Natural Science Foundation of China, NSFC: 51674028; Ministry of Science and Technology of the People's Republic of China, MOST: 2016IM010300; Guangxi Innovation-Driven Development Project: GKAA17202008","This work was supported by the National Natural Science Fund of China [No.51674028]; the Innovative Method Project of Ministry of Science and Technology of China [2016IM010300]; and the Guangxi Special Funding Program for Innovation-Driven Development [GKAA17202008].",,,,,,,,,,"Mücke, G., Karhausen, K.F., Pütz, P.D., Methods of describing and assessing shape deviations in strips (2002) Metal Plant Technol Int, 25 (3), pp. 58-60; Zheng, X.T., Li, H.B., Zhang, J., C-shaped warp control of hot-rolled thin strip coiling process // Proceedings of Chinese Society for Metals Annual Meeting of Young Scientists.

In this article, the structure of the ferromagnetic bridge is optimized by analyzing the magnetic circuit structure of Numerical anlysis of an axial-radial flux type fully superconducting synchronous motor (ARFTFSSM). The three-dimensional finite-element model of the motor is established by using the finite-element method, and the changes of air gap flux density and back electromotive force are compared through the finite-element prediction. The results show that the optimized ferromagnetic bridge has better magnetic regulation performance. On this basis, the eddy current distribution and eddy current loss of two kinds of ferromagnetic bridge structures are further compared and analyzed.

Therefore, it is vital to examine the impact of cracks on the behavior of bridges. To this end, in this paper, the effect of parameters, such as the crack's depth, magnitude and speed of the moving force, and its inertial effects on the dynamic behavior of a simply-supported Euler-Bernoulli beam, representing the bridge girder, are scrutinized. The results are obtained by the Galerkin Method (GM) and Finite Element Method (FEM) and are validated with those achieved by Finite Element Analysis in ANSYS software. Finally, the parameters that affect the dynamic behavior of the cracked beam are normalized and the analyses are performed by adopting the Galerkin Method. The results of this study revealed that in the case of a moving mass, the stiffness reduction due to the presence of a crack has a marginal impact on altering the beam response in comparison with the moving load model. It is also demonstrated, for certain values of the crack's depth, the response of the structure under a moving mass is not always greater than that of a moving load, especially for the relatively large moving forces with high velocities. On the other hand, existence of the cracks is proved to be crucial as it may cause a complete elimination of the inertial effects for some certain values of the moving force weight and velocity. © 2020","Euler-Bernoulli beam; Finite element method (FEM); Galerkin method (GM); Local stiffness reduction (LSR) method; Moving force","Beams and girders; Galerkin methods; Dynamic behaviors; Effect of parameters; Euler Bernoulli beams; Inertial effect; Moving load models; Simply supported; Static and dynamic response; Stiffness reduction; Finite element method",,,,,,,,,,,,,,,,"Christides, S., Barr, A.D.S., One-dimensional theory of cracked Bernoulli-Euler beams (1984) Int.

These specimens were designed to have reinforcement details that had similar features to two different types of pier cap beams used in the Champlain Bridge in Montréal, Canada. The objectives were to examine the behavior of variable-depth cap beams at service loading and at failure to analyze the effectiveness of crack control reinforcement and inclined reinforcement, as well as to investigate the influence of added external horizontal post-tensioning. The observed cap beam responses were compared with two prediction models: sectional analyses and nonlinear finite-element analyses. The amount of crack control reinforcement was important in controlling crack widths at the service load level. The inclined shear reinforcement was found to be effective in resisting shear. Horizontal post-tensioning was effective in reducing crack widths and increasing the overall stiffness of the cap beams but did not lead to significant increases in shear strength. Failure shears predicted by the sectional analyses were conservative. Nonlinear finite element analyses gave good predictions of the complete behavior and strength of the cap beams. © 2020 American Society of Civil Engineers.",,"Bridges; Finite element method; Horizontal wells; Piers; Reinforced concrete; Controlling crack; Non-linear finite-element analysis; Overall stiffness; Prediction model; Reinforced concrete pier; Sectional analysis; Service loading; Shear reinforcement; Concrete beams and girders",,,,,,,,,,,,,,,,"(2014) AASHTO LRFD Bridge Design Specifications, , AASHTO. 7th ed.

This research aims to develop mathematical models for the optimal design of crane bridge girders by minimizing their weight and thus reducing the operating energy. I- and H-shaped crane girders with compact sections of A36 steel are studied according to the American Institute of Steel Construction-Allowable Stress Design method. A code was written to optimize girder sectional dimensions for spans of 5–50 m with crane capacities of 50–500 kN. The design criteria are the allowable bending, shear stresses and deflections. The obtained dimensions were utilized as target values to propose neural models for girder design using a back-propagation network method. The models were validated using two network training performance parameters: the mean square error and regression plots. The obtained results of the mathematical models were used as input for finite-element analysis of double crane girders. The generated models should aid crane designers in efficiently selecting the lightest girders and crane manufacturers in providing cost-effective design solutions for a variety of crane configurations to suit the different needs of end users. © 2020, Springer Nature Switzerland AG.","Crane bridge girder neural model; Crane girder mathematical model; H-crane girder section; I-crane girder section; Lightest girder section",,,,,,,,,,,,,,,,,"Abid, M., Akmal, M., Wajid, H., Design optimization of box type girder of an overhead crane (2015) Iranian Journal of Science and Technology, Transactions of Mechanical Engineering, 39 (M1), pp. 101-112; Ahmid, A., Le, V., Dao, T., Optimization procedure for an I-beam crane subjected to yield and buckling criteria (2017) 2017 World Congress on Advances in Structural Engineering and Mechanics (ASEM17), pp. 1-12. , Ilsan, Seoul, Korea, ASEM; (1989) AISC Manual of Steel Construction: Allowable Stress Design (AISC 316-89), , 9th edn; Warrendale, P.A., (2003) Guide for the Design and Construction of Mill Buildings (AIST TR-13); Warrendale, P.A., (2018) AIST Specification for Electrical Overhead Traveling Cranes for Steel Mill Service (AIST TR- 06); (2007), Eurocode 3: Design of steel structures-crane supporting structures.

The mining of the longwall panel No. 1307 may damage the Majiagou Bridge. In this study, we predicted the mining-induced bridge movements using the finite element method (FEM) to examine whether the progressive mining of the longwall panel will pose a negative impact on the Majiagou Bridge. We reconstructed detailed three-dimensional models of the four sub-bridges by considering the superstructures and substructures. The input mechanical properties of the strata are estimated by calibrating with available field monitoring data. Effect of traffic load on the bridge subsidence is also accounted. The numerical predictions are: (1) after the panel No. 1307 is mined, the maximum vertical and horizontal displacements of the four bridges are 61.2 mm and 84.8 mm respectively, which occur on the sub-bridge D that is closest to the longwall panel, (2) traffic load has much less pronounced effect on the Majiagou Bridge than that due to mining, and (3) the maximum tilt and horizontal strain of the sub-bridges are 3.42e−5 m/m and 2.19e−5 m/m, which occur on sub-bridge B and sub-bridge A, respectively. In terms of tilt, the Majiagou Bridge is safe whereas it is to be damaged in terms of horizontal movement that is more critical in causing structural damage.

Five geometric and structural key parameters that influence (APJs) responses under thermal movements are studied: (1) joint length; (2) joint thickness; (3) joint width; (4) anti-bonding mat; (5) movement-aid spring. The viscoelastic computational finite element models are based on properties determined with a special cyclic coaxial shear test (CAST) and validated by an integrated approach incorporating cold temperature repeated movement capacity tests with a special Joint Movement Simulator (JMS) and a 3-Dimensional Digital Image Correlation system (3D DIC). It was found that the increase of joint width significantly reduces the stress at the interface between the mastic asphalt and APJ. The results also showed, that thin joints generate lower stress levels in APJ under thermal condition. Moreover, peak stresses in APJ appeared controlled mainly by the total size of the debonded region and the horizontal movement applied. The main findings are considered valuable for superior structural design, geometry selection and construction guidelines for APJ. © 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group.","bridge; cracking; debonding; expansion joint; finite element; pavement; thermal movement","Asphalt pavements; Bridges; Crack initiation; Debonding; Expansion; Expansion joints; Mastic asphalt; Pavements; Structural design; Coaxial shear tests; Cold temperatures; Digital image correlations; Finite element modelling; Horizontal movements; Integrated approach; Structural response; Thermal movements; Finite element method",,,,,,,,,,,,,,,,"(2005), Fahrbahnubergange aus Polymerbitumen, Bundesamt fur Strassen.

The analysis of the influence of moving load on bridges is carried out numerically or experimentally and can be traced in the literature since the year 1849. The first impulse was the collapse of the Chester Rail Bridge in England in the year 1847. The present paper analyses the effect of the moving load on a two-span bridge, both numerical and experimental way. The planar model of the vehicle and the bridge is adopted. The bridge is modeled as Bernoulli-Euler beam. The heavy vehicle is modeled as a discrete computational model with 8 degrees of freedom. Two approaches are used in numerical modeling. For the first time, the task is solved by the finite element method in the environment of the program system ADINA. The Newmark's method is used for the solution of equations of motion. The classic approach is used for the second time. A discrete computational model of a bridge with two degrees of freedom is used. Equations of motion are solved numerically in the environment of program system MATLAB by the Runge-Kutta 4th order method. The influence of vehicle speed on vertical deflections in the middle of individual bridge fields is analyzed in the speed range from 0 to 130 km/h with a step of 5 km/h. The detailed comparison of both numerical approaches is made at a vehicle speed of 70 km/h. The deflections of the bridge and the deflection of the vehicle are compared with each other. The correctness of the assumptions used in the numerical solutions was verified by measurement on a model beam in the laboratory. The results of the experimental tests were compared with the results of the numerical solution. © 2020 Veronika Valašková, et al.","Bridge; Dynamic response; Experimental test; Moving load; Numerical simulation; Vehicle","Bridges; Computation theory; Computational methods; Degrees of freedom (mechanics); Equations of motion; MATLAB; Numerical models; Runge Kutta methods; Computational modelling; Equation of motion; Experimental approaches; Experimental test; Moving load; Numerical approaches; Numerical solution; Program systems; Two span bridge; Vehicle speed; Vehicles",,,,,"Vedecká Grantová Agentúra MŠVVaŠ SR a SAV, VEGA: 1/0006/20","The project was performed with the financial support of the Slovak Grant National Agency VEGA 1/0006/20.",,,,,,,,,,"Appendix, Willis R., (1849) Report of the Commissioners Appointed to Inquire into the Application of Iron to Railway Structures, , Stationary Office, London; Stokes, G.

Specifically, in solenoid valves, an imprecised roller crimping (or forming) adversely affect the desired magnetic performance of the valves. Furthermore, in-depth evaluations of the formed shape using hardware and lab testing are extremely challenging cost wise and time consuming as well. However, utilizing simulation technique such as finite element analysis (FEA) to understand the in-sights of roller formed assemblies of a solenoid valve (or other products) could be an effective way to minimize overall cost and time involved in the product development. Therefore, a three-dimensional non-linear FEA model of roller crimping simulation was established in ANSYS Workbench Mechanical, and the predicted results were correlated with real hardware data to prove the technique & process adopted. Then the design was improved computationally to eliminate the magnetic core's flux-bridge distortion issue of a solenoid valve, and finally the design was validated through hardware testing. © 2020 SAE International.

This paper conducted a numerical study to investigate the static behavior of damaged stud shear connectors that were embedded in ultra high performance concrete (UHPC). Parameters included damage degree and damage location. The material nonlinear behavior was characterized by multi-linear stress-strain relationship and damage plasticity model. The results indicated that the shear strength was not sensitive to the damage degree when the damage occurred at 2/3d (d is the stud diameter) from the stud root. An increased stud area would be engaged in resisting shear force as the distance of damage location from stud root increased and the failure section becomes inclined, resulting in a less reduction in the shear strength and shear stiffness. The reduction factor was proposed to consider the degradation of the shear strength of the damaged stud. The reduction factor can be calculated using two approaches: a linear relationship and a square relationship with the damage degree corresponding to the shear strength dominated by the section area and the nominal diameter of the damaged stud. It was found that the proposed method is preferred to predict the shear strength of a stud with initial damage. © 2020 Techno-Press, Ltd.","Composite bridges; Finite element analysis; Initial damage; Shear strength; Stud shear connector; Ultra high performance concrete (UHPC)",,,,,,"2018-ZJKJ-02; National Natural Science Foundation of China, NSFC: 51908122; Fundamental Research Funds for the Central Universities; Jilin Province Key R&D Plan Project: 2017YFC07034","This study was supported by the National Natural Science Foundation of China (Grant No. 51908122), the National Key R&D Plan (2017YFC07034), “Zhishan” Scholars Programs of Southeast University, the Technology R&D Project of China Communications Construction Company (Grant No. 2018-ZJKJ-02), and the Fundamental Research Funds for the Central Universities.

This research study evaluated the structural behavior of bolted lap shear connections with such materials by means of experimental load testing and finite element (FE) modeling. The main focus of this study is the ultimate strength of the connection, but the slip critical behavior was studied as well to give a more complete understanding of the connection response. Eight specimens having steel and polypropylene (PP) filler plates of various thicknesses were tested in the laboratory and the collected measurements were utilized for numerical validation of a FE model. Subsequently, three parametric studies were conducted using the validated FE models to provide insight into the general behavior of connections with a variety of filler plates that could be used as thermal breaks. In addition, an extreme notional case of filler plates having no strength and stiffness was also considered. This paper presents the experimental program and the FE model, discusses the parametric study evaluating a range of potential filler plate materials, and compares them with existing design code and other equations proposed in the literature.

Although significant research efforts during the last two decades have resulted in an extensive number of parametric identification algorithms, most of them are certainly not directly applicable for modal parameter extraction. So, based on this, the aim of the present work is to develop a technique for modal parameter extraction from the measured signal. Design/methodology/approach: A survey and classification of the different modal analysis methods are made; however, the focus of this thesis is placed on modal parameter extraction from measured time signal. Some of the methods are examined in detail, including both single-degree-of-freedom and multi-degree-of-freedom approaches using single and global frequency-response analysis concepts. The theory behind each of these various analysis methods is presented in depth, together with the development of computer programs, theoretical and experimental examples and discussion, in order to evaluate the capabilities of those methods. The problem of identifying properties of structures that possess close modes is treated in particular detail, as this is a difficult situation to handle and yet a very common one in many structures. It is essential to obtain a good model for the behavior of the structure in order to pursue various applications of experimental modal analysis (EMA), namely: updating of finite element models, structural modification, subsystem-coupling and calculation of real modes from complex modes, to name a few. This last topic is particularly important for the validation of finite element models, and for this reason, a number of different methods to calculate real modes from complex modes are presented and discussed in this paper. Findings: In this paper, Modal parameters like mode shapes and natural frequencies are extracted using an FFT analyzer and with the help of ARTeMiS, and subsequently, an algorithm has been developed based on frequency domain decomposition (FDD) technique to check the accuracy of the results as obtained from ARTeMiS. It is observed that the frequency domain-based algorithm shows good agreement with the extracted results. Hence the following conclusion may be drawn: among several frequency domain-based algorithms for modal parameter extraction, the FDD technique is more reliable and it shows a very good agreement with the experimental results. Research limitations/implications: In the case of extraction techniques using measured data in the frequency domain, it is reported that the model using derivatives of modal parameters performed better in many situations. Lack of accurate and repeatable dynamic response measurements on complex structures in a real-life situation is a challenging problem to analyze exact modal parameters. Practical implications: During the last two decades, there has been a growing interest in the domain of modal analysis. Evolved from a simple technique for troubleshooting, modal analysis has become an established technique to analyze the dynamical behavior of complex mechanical structures. Important examples are found in the automotive (cars, trucks, motorcycles), railway, maritime, aerospace (aircrafts, satellites, space shuttle), civil (bridges, buildings, offshore platforms) and heavy equipment industry. Social implications: Presently structural health monitoring has become a significantly important issue in the area of structural engineering particularly in the context of safety and future usefulness of a structure. A lot of research is being carried out in this area incorporating the modern sophisticated instrumentations and efficient numerical techniques. The dynamic approach is mostly employed to detect structural damage, due to its inherent advantage of having global and location-independent responses. EMA has been attempted by many researchers in a controlled laboratory environment. However, measuring input excitation force(s) seems to be very expensive and difficult for the health assessment of an existing real-life structure. So Ambient Vibration Analysis is a good alternative to overcome those difficulties associated with the measurement of input excitation force. Originality/value: Three single bay two storey frame structure has been chosen for the experiment. The frame has been divided into six small elements. An algorithm has been developed to determine the natural frequency of those frame structures of which one is undamaged and the rest two damages in single element and double element, respectively. The experimental results from ARTeMIS and from developed algorithm have been compared to verify the effectiveness of the developed algorithm. Modal parameters like mode shapes and natural frequencies are extracted using an FFT analyzer and with the help of ARTeMiS, and subsequently, an algorithm has been programmed in MATLAB based on the FDD technique to check the accuracy of the results as obtained from ARTeMiS. Using singular value decomposition, the power Spectral density function matrix is decomposed using the MATLAB program. It is observed that the frequency domain-based algorithm shows good consistency with the extracted results. © 2019, Emerald Publishing Limited.","Modal analysis; Modal parameter; Mode shape; Natural frequency; Parameter extraction","Automotive industry; Composite beams and girders; Damage detection; Degrees of freedom (mechanics); Domain decomposition methods; Extraction; Fast Fourier transforms; Finite element method; Frequency division multiplexing; Frequency response; MATLAB; Natural frequencies; Offshore oil well production; Offshore structures; Parameter estimation; Parameter extraction; Singular value decomposition; Soil structure interactions; Space platforms; Space shuttles; Spectral density; Structural analysis; Structural frames; Structural health monitoring; Ultrasonic devices; Vibration analysis; Design/methodology/approach; Experimental modal analysis; Frequency domain decomposition; Frequency response analysis; Modal parameters; Mode shapes; Parametric identification algorithms; System identification methods; Modal analysis",,,,,,,,,,,,,,,,"Asmussen, J.C., Brincker, R., (1996) Estimation of Frequency Response Function by Random Decrement, , Department of Building Technology and Structural Engineering Aalborg University; Bendat, J.S., Piersol, A.G., (1986) Random Data, Analysis and Measurement Procedures, , John Wiley & Sons; Brincker, R., Andersen, P., Cantieni, R., (2001) Identification and level 1 damage detection of the Z24 highway bridge by frequency domain decomposition; Brincker, R., Zhang, L., Andersen, P., Output-only modal analysis by frequency domain decomposition (2000) Proceedings of ISMA 25, Vol. 2; Cremona, C.F., Brandon, J.A., Modal identification algorithm with unmeasured input (1992) Journal of Aerospace Engineering, 5 (4), pp. 442-449; Giraldo, D.F., Song, W., Dyke, S.J., Caicedo, J.M., Modal identification through ambient vibration: comparative study (2009) Journal of Engineering Mechanics, 135 (8), pp. 759-770; James Hu, S.-L., Li, P., Vincent, H.T., Li, H., (2011) Journal of waterway, port, coastal, and ocean engineering, 137 (5), pp. 234-245; Juang, J.N., Pappa, R.S., An eigensystem realization algorithm for modal parameter identification and modal reduction (1985) Journal of Guidance, Control and Dynamics, 8 (5), pp. 620-627; Randall, R.B., Zurita, G., Wardrop, T., Extraction of modal parameters from response measurements (2004) Investigation & Desarrollo, (4), pp. 5-12; Zhang, D.-W., Wei, F.-S., Extracting modes of constrained structure with elastic supports from free test data (2007) Journal of Aerospace Engineering, 20 (1), pp. 1-9; Zhang, L., Brincker, R., Andersen, P., (2002) An unified approach for two-stage time domain modal identification; Bendat, J.S., Piersol, A.G., (1993) Engineering Applications of Correlation and Spectral Analysis, , John Wiley & Sons; Brincker, R., Zhang, L., Andersen, P., Modal identification from ambient responses using frequency domain decomposition (2000) Proceedings of the 18th International Modal Analysis Conference, pp. 625-630. , San Antonio, TX; Felber, A.J., (1993) Development of a hybrid bridge evaluation sytem, , PhD thesis, Department of Civil Engineering, University of British Columbia, Vancouver; Ibrahim, S.R., Milkulcik, E.C., The experimental determination of vibration test parameters from time responses (1976) The Shock and Vibration Bulletin, 46 (5), pp. 187-196; Rodrigues, J., Brincker, R., Andersen, P., Improvement of frequency domain output-only modal identification from the application of the random decrement technique; Van Overshcee, P., De Moor, B., (1996) Subspace Identification for Linear Systems, , Kluwer Academic Publishers; Vold, H., Kundrat, J., Rocklin, G.T., Russel, R., (1982) A multi-input modal estimation algorithm for mini-computer, , SAE Technical Paper Series, 820194","Kaium, S.A.; Department of Civil Engineering, India; email: sakaium@hotmail.com",,,"Emerald Group Holdings Ltd.",,,,,17579864,,,,"English","Int.

In addition, the response spectrum and dynamic time history methods were used to analyze and compare its seismic performance. The results show that the transverse stiffness of the bridge’s main truss was relatively low. After the reinforcement, the vertical and the torsional frequencies of the bridge significantly increased by 24% and 32%, respectively. under the same condition, the axial force at the fixed end of the top chord of the strengthened bridge was reduced by roughly 29%, and the transverse and the vertical displacement at the middle of the top chord span were reduced by roughly 10% and 20%, respectively. Thus, the reinforcement measures significantly improved the vertical stiffness of the bridge. For this bridge, the dynamic time history analysis played a more controlling role in the seismic design. Among the three types of seismic waves, the El Centro wave yielded the largest transverse displacement result and hence, should preferably be used to assess the deflections. © 2020, © 2020 The Author(s).

However, current studies barely focus on the redistribution of interface friction after bolt fracture. Therefore, this paper will specifically carry out finite element analysis on the redistribution of interface friction caused by fractured bolts. Firstly, the refined finite element model of friction-type high-strength bolted joint is used to investigate the variation of interface friction under uniform temperature as well as the distribution of interface friction in different areas. Furthermore, random selection method is introduced to explain how the quantity and location of fractured bolts influence the redistribution of interface friction. Finally, the mathematical model of friction redistribution is built to describe the redistribution of interface friction in the high-strength bolted frictional steel connection after bolt fracture. After validation, the mathematical model can well describe the redistribution of interface friction caused by fractured bolts, which can provide useful reference for the frictional steel connection design of high strength bolts. © 2020 University of Kuwait.

The floating deck structures of HTABs and TABs will commonly produce longitudinal deformation and rotate under the effect of temperature and the temperature gradient, which will cause bending deformation at anchorages of fixed-end hangers. This bending deformation can generate adverse bending stress for hangers and decrease the strength and fatigue properties of the seven-wire strands in the hangers. Firstly, theoretical derivation and finite element analysis are conducted to study the bending stress of hangers that is caused by bending deformation. We find that bending stress of hangers is mainly generated by lateral bending caused by the difference in longitudinal displacement at both ends of the hangers under the effect of temperature. Subsequently, the ultimate tensile strength of the seven-wire strands under lateral bending is obtained by FEM and an experimental study. The ultimate tensile strength of the seven-wire strands could decrease by 23.3% when lateral bending is considered. Moreover, the relationship between the fatigue properties of the seven-wire strands and lateral bending is obtained based on observing the ultimate tensile strength under lateral bending. Lateral bending significantly influences the fatigue properties of the seven-wire strands. When the lateral bending angle reaches about 50 mrad, the fatigue resistance of the seven-wire strands drop by almost 40%. The considerable decrease in the strength and fatigue properties of the seven-wire strands indicates that lateral bending has a significant adverse influence on hangers that consist of seven-wire strands. Finally, it is advised to use the tied arch structure for HTABs and TABs to mitigate the adverse influence of lateral bending on hangers. © 2020 by the authors.","Fatigue properties; Hangers; Lateral bending; Seven-wire strands; Strength",,,,,,,,,,,,,,,,,"Liu, J.F., Li, Y.B., Zhang, Q.W., Mechanical behavior of damaged strand suspender with asymmetric broken wires in arch bridges (2019) J.

Additionally, the finite element model of the part where the collapse initiated was created and loaded in accordance with the operation procedures of the gantry during the incident. Finally, on-site investigation and finite element analysis results revealed that collapse of the gantry occurred by exceeding the shear capacity of the bolts in the connections. Moreover, the exceedance of the shear capacity was the consequence of unexpected operating practices used by the workers during the incident, which caused unforeseen shear stress concentration in the bolts. © 2020 Elsevier Ltd","Accident investigation; Gantry failure; Metro crossing bridge; Underdeck maintenance gantry","Bolts; Disasters; Failure (mechanical); Finite element method; Maintenance; Occupational risks; Shear stress; Accident investigation; Istanbul , Turkey; On site investigations; Operating practices; Operation procedure; Shear capacity; Underdeck maintenance gantry; Bridges",,,,,,,,,,,,,,,,"Mahmoud, K.M., Advances in Cable-Supported Bridges (2006), pp. 57-85. , Taylor & Francis Group plc London; Witts, C., The Severn Estuary Crossings (2017), Amberley Publishing Limited United Kingdom; Royal Academy of Engineering, Accidents & Agenda: An examination of the processes that follow from accidents or incidents of high potential in several industries and their effectiveness in preventing further accidents (2005), The Royal Academy of Engineering London; Kassabian, P.E., McCall, M., Dusenberry, D.O., Konicki, W.P., (2011), Collapse of the I-280 Maumee River Bridge Launching Gantry in Toledo Ohio, ASCE 2011 Structures Congress, Las Vegas, Nevada, 14–16 April; Furtner, P., Stöger, M., Wenzel, M., (2016), SHM of Golden Horn Metro Crossing Bridge in Istanbul – Initial Assessment Permanent Monitoring and Data Analysis, Proceedings of Ibridge 2016, Istanbul, 08–10 August; HKS, (2017), ABAQUS/Standard CAE, Hibbit Karlsson Sorenson Inc., Version. 2017; (2003), DOT/FAA/AR-MMPDS-01, Metallic materials properties development and standardization, Office of Aviation Research, Virginia, USA; Scheider, I., Brocks, W., Cornec, A., Procedure for the determination of true stress-strain curves from tensile tests with rectangular cross-section specimens (2004) J.

The bridge deck is composed of three parts: the central deck, and two extensions, one at each side. These extensions can rotate around hinges placed at the central deck edges. The central deck and the extension decks are supported by their respective cable system. Performing a sectional test of a rigid bridge section only two DOF should be considered. However, here, 6 DOF should be considered in the modelling of the elastic problem. This is a reduced model based on a FEM model of the whole bridge, and is the base for the design of the wind tunnel tests. Aeroelastic tests have been performed in the IDR ACLA-16 wind tunnel. The influence of the angle of attack of the windward extension deck on the bridge stability has been studied. The complexity of the bridge deck motion is described considering both the oscillation frequencies and the modal shapes. Stability ranges are presented in terms of reduced wind speed and compared to other long span bridges. In a configuration, the stability range achieved is more than twice that of a similar bridge. © 2020 Elsevier Ltd","Aeroelasticity; Articulated cross section bridge; Stability; Wind tunnel tests","Aeroelasticity; Angle of attack; Bridge decks; Cable stayed bridges; Cables; Convergence of numerical methods; Stability; Testing; Wind stress; Aerodynamic instability; Bridge section; Elastic problems; Experimental investigations; Long-span bridge; Oscillation frequency; Reduced model; Wind tunnel tests; Wind tunnels",,,,,,,,,,,,,,,,"Astiz, M.Á., Wind-induced vibrations of the Alconétar bridge, Spain (2010) Struct.

In this study, 378 finite element models were analyzed to reveal the quantitative influence of local and overall initial deflections on load-bearing capacity. In the parametric analyses, nine combinations of the amplitude of the local and overall initial deflections were considered. In addition, normalized width-thickness and slenderness ratios were varied with ranges from 0.3 to 1.8 and from 0.3 to 1.5, respectively. As a result, the initial deflection influence coefficient was proposed to describe the quantitative influence on load-bearing capacity and formulated as functions of the local and overall initial deflections, normalized width-thickness and slenderness ratios. The accuracy of the proposed formula was verified through the comparison with the FEA results including additional 108 FEA results with normalized slenderness ratio of 0.9 and 1.2. © 2019 Elsevier Ltd","Axial compression; Coupled buckling; Initial deflections; Load-bearing capacity; Parametric formulae; Unstiffened square welded box section","Axial compression; Bearing capacity; Box girder bridges; Loads (forces); Welding; Box section; Coupled buckling; Initial deflection; Load-bearing capacity; Parametric formulae; Deflection (structures)",,,,,"China Scholarship Council, CSC: 201606650012","The research described in this paper is financially supported by China Scholarship Council (No. 201606650012 ).

Most of the current research on SHM focuses on developing either purely experimental models or stays on purely numerical data without real application validation. The potential of SHM methods however could be unlocked, having accurate enough numerical models and classifiers that not only recognize but also locate or quantify the structural damage. The present study focuses on the implementation of a methodology to bridge the gap between SHM models with numerically generated data and correspondence with measurements from the real structure to provide reliable damage predictions. The methodology is applied in a composite carbon fiber tube truss structure which is constructed, using aluminum elements and steel bolts for the connections. The composite cylindrical parts are produced on a spinning axis by winded carbon fibers, cascaded on specified number of plies, in various angles and directions. 3D FE models of the examined cylindrical parts are developed in robust finite element analysis software simulating each carbon fiber ply and resin matrix and analyzed against static and dynamic loading to investigate their linear and nonlinear response. In addition, experimental tests on composite cylindrical parts are conducted based on the corresponding analysis tests. The potential damage to the structure is set as loose bolts defining a multiclass damage identification problem. The SHM procedure starts with optimal modeling of the structure using an updated Finite Element (FE) model scheme, for the extraction of the most accurate geometrical and physical numerical model. To develop a high-fidelity FE model for reliable damage prediction, modal residuals and mode shapes are combined with response residuals and time-histories of strains and accelerations by using the appropriate updating algorithm. Next, the potential multiclass damage is simulated with the optimal model through a series of stochastic FE load cases for different excitation characteristics. The acceleration time series obtained through a network of optimally placed sensors are defined as the feature vectors of each load case, which are to be fed in a supervised Neural Network (NN) classifier. The necessary data processing, feature learning and limitations of the NN are discussed. Finally, the learned NN is tested against the real structure for different damage cases identification. © 2020, The Society for Experimental Mechanics, Inc.","Damage identification; Modal identification; Neural networks; Optimal modeling; Structural health monitoring","Carbon fibers; Cost engineering; Cost reduction; Damage detection; Data handling; Dynamic loads; Machine learning; Neural networks; Numerical methods; Numerical models; Spinning (fibers); Steel fibers; Stochastic models; Stochastic systems; Structural dynamics; Structural health monitoring; Structural optimization; Damage Identification; Damage prediction; Finite element modelling (FEM); Identification of structures; Machine learning techniques; Modal identification; Model validation; Neural-networks; Optimal model; Real structure; Finite element method",,,,,"T6YBII-00478","Acknowledgments This research has been co-financed by the European Union and Greek national funds through the Operational Program Competitiveness, Entrepreneurship and Innovation, under the call INDUSTRIAL MATERIALS (project code: T6YBII-00478).",,,,,,,,,,"Soutis, C., Carbon fiber reinforced plastics in aircraft construction (2005) Mater.

However, the reactions from the approach slab can influence the mechanical behaviors of jointless bridges. The most common type of approach slab in jointless bridges is the Grade Flat Approach Slab (GFAS). The length of the approach slab, the sliding material and the subgrade material can affect the stresses of the approach slabs and the girders. The influence of the approach slabs was usually neglected. In this paper, one Deck-Extension Bridge (DEB) was chosen as the case study. The finite element models of the girders and the GFAS was built. Based on the force-displacement curve and friction coefficient obtain from the lab test, the horizontal and vertical springs were used to simulate the friction in the sliding materials and the supports under the GFAS. The results show that the simulation method of simplified spring is more constrained than the simulation method of shell element, the influence laws of the two connection structures of hinged and fixed are different. The influence of the parameters on the side span is greater than that of the mid span. © 2021 Taylor & Francis Group, London.",,"Beams and girders; Bridges; Approach slabs; Case-studies; Finite element modelling (FEM); Force-displacement curves; Friction coefficients; Jointless bridges; Mechanical behavior; Sliding materials; Subgrade materials; Temperature variation; Friction",,,,,"National Natural Science Foundation of China, NSFC: 51508103, 51578161, 51778148","This research was supported by the National Natural Science Foundation of China (grant numbers 51508103, 51778148, and 51578161).

However, the conventional Reinforced Concrete (RC) link slab tends to produce cracks that cause leakage and deterioration. In order to improve the crack resistance of RC link slab, Ultra-High Performance Concrete (UHPC) link slab is proposed. Based on the test results of UHPC link slab under monotonic tensile loading, the validity and accuracy of the Finite Element Model (FEM) built by ABAQUS was verified. The parametric analyses based on the verified FEM were carried out to study the influence of different parameters on the tension behaviors of UHPC link slab. The results indicate that with an increase in rubber sheet length or reinforcement ratio, the maximum concrete stress at top fiber decreased by 13.8% and 17.9%, respectively. The tension stiffness is mainly influenced by the rubber sheet length and link slab thickness. © 2021 Taylor & Francis Group, London.",,"ABAQUS; Bridges; Cracks; Deterioration; High performance concrete; Life cycle; Rubber; Crack resistance; Deck joints; Finite element modelling (FEM); Jointless bridges; Link slabs; Monotonics; Multi-spans; Rubber sheet; Sheet lengths; Simply-supported girder bridges; Reinforced concrete",,,,,"National Natural Science Foundation of China, NSFC: 51508103, 51578161, 51778148","This research was supported by the National Natural Science Foundation of China (grant numbers 51508103, 51778148, and 51578161).

In-situ tests of a two-span post-tensioned bridge loaded with three vehicles of 38-ton mass each formed the input of this study. On the basis of the results of these measurements an advanced FEM model of the structure was developed for which the sensitivity analysis was performed for chosen uncertainty sources. Three uncorrelated random variables representing material uncertainties, imperfections of positioning and total mass of loading vehicles were indicated. Afterwards, two alternative FE models were created based on a fully parametrised geometry of the bridge, differing by a chosen global parameter – the skew angle of the structure. All three solid models were subjected to probabilistic analyses with the use of second-order Response Surface Method in order to define the features of structural response of the models. It was observed that both the ranges of expected deflections and their corresponding mean values decreased with an increase of the skewness of the bridge models. Meanwhile, the coefficient of variation and relative difference between the mean value and boundary quantiles of the ranges remain insensitive to the changes in the skew angle. Owing to this, a procedure was formulated to simplify the process of load testing design of typical bridges differing by a chosen global parameter. The procedure allows - if certain conditions are fulfilled - to perform probabilistic calculations only once and use the indicated probabilistic parameters in the design of other bridges for which calculations can be performed deterministically. © 2020 Sciendo.

The sensor element is interpreted as mechanical transducer element focusing on the two most prominent readout principles, capacitive and piezoresistive. A capacitive sensor is analytically assessed for a first dimensioning, and the relevance of finite element method simulations is emphasized. An exemplary process integration scheme is presented, and the impact of chip-package interaction due to mechanical stress is discussed. Package-induced stress effects can be significantly reduced using reference elements in a differential bridge configuration. The capacitive sensor part concludes with a calibration flow to achieve the targeted sensor performance. Piezoresistive sensors are discussed in a similar approach. In addition, a discussion of scaling effects, a review of the piezoresistive effect, and specifics of piezoresistor positioning are given. © 2020 Elsevier Inc.

The SiC module is consisted with 8 self-designed 3.3 kV30A SiC Schottky diodes (SBDs), in which each bridge arm is connected by double SBD chips to achieve 60A current. Q3D software is used to establish simulation model of 3.3 kV 60A high-voltage H-bridge SiC diode module. The parasitic parameters are extracted from the current circuits. By establishing the geometric model and finite element model, finite element analysis software ANSYS is used to calculate steady-state thermal conduction, and the for med temperature gradient distribution shows that the distribution of the temperature field is reasonable. Under the condition of the test at room temperature and static, the module voltage drop is about 2.1 V, the leakage current is less than 5 uA, and the breakdown voltage is more than 3700 V, respectively. The fabricated 3300 V devices exhibit large safety margin. The insulation voltage exceeds 7000V,thus ensure the safety of the system. The thermal resistance of the chip is about 0.21 K/W, which is basically consistent with the simulation results. © 2020 Trans Tech Publications Ltd, Switzerland.","SiC Power SBD Modules; SiC SBD; Silicon carbide","Bridge circuits; Computer software; Diodes; Finite element method; Schottky barrier diodes; Silicon carbide; Temperature; Finite element analysis software; Geometric modeling; Insulation voltage; Parasitic parameter; SiC Schottky diode; Simulation model; Temperature gradient distribution; Thermal conduction; Power semiconductor diodes",,,,,,"The research and development work is undertaken by Yangzhou Guoyang Electronics Co., Ltd., researchers from the State Key Laboratory of Wide Band Gap Semiconductor Power Electronics and Nanjing Institute of Electronic Devices, and I would like to express my gratitude to the relevant personnel.",,,,,,,,,,"Friedrichs, P., SiC power devices for industrial applications (2010) International Power Electronics Conference, pp. 3241-3248. , [C]; Fujii, K, Noto, Y, Oshima, M, 1-MW solar inverter with boost converter using all SiC power module[C] (2015) 17th European Conference on Power Electronics & Applications, pp. 1-10; SiC power devices for industrial applications [C] (2010) International power Electronics conference, pp. 3241-3248. , Fricdrichs; Chen, Y., Tan, J., Bai, S., Development of 6.5kV 50A 4H-SiC JBS diodes IEEE IFWS 2017, , [C] Shen Zhen; TAKAKU, T, WANG, H, MATSUDA, N, Development of 1 700 V hybrid module with Si-IGBT and SiC SBD for high efficiency AC 690 V application (2015) 9th ICPE-ECCE Asia, pp. 844-849. , [C]; LUECHINGER, C., Ribbon Bonding-A Scalable Interconnect for Power QFN Packages [C] (2007) 9th Electronics Packaging Technology Conference, pp. 47-54. , Singapore","Fengbin, H.; Yangzhou Guo Yang Electronics.

In recent decades, however, they have been replaced by bars made from Carbon Fiber Reinforced Polymer (CFRP), as a material with high tensile strength and corrosion resistance, to address several concerns with steel bars such as their application costs and difficulties, and also their durability. Post-tensioning these sheets can be a new efficient method in strengthening the beams and utilizing the high strength of these material.This study has focused on the flexural behavior of beams reinforced by Post-tensioned non-bonded CFRP sheets. 15 beams were categorized in 3 groups of 5m-, 10m-, and 15m-span in order to evaluate the effect of some parameters such as level of post-tensioning, sheet length, and beam span on its load capacity, failure mode, ductility, and cracks behavior. The results indicate that even though the increase in posttensioning levels improves the effectiveness of the method, but this capacity improvement is much more for small span beams especially when CFRP sheets are 90% of the beam span, compared to long span beams. There has been a noticeable capacity increase around 50% in the beams when decreasing the sheet length from 90% to 45% of the beam span and also causing 11-14% increase in ductility in various conditions. © 2020, Faculty of Civil Engineering, Semnan University.

These structures are difficult to characterise in terms of real structural geometry and material mechanical characteristics and in many cases have been subjected to structural retrofitting or modifications that are not sufficiently documented. The continuous upgrading of the railway network implies the need to provide a structural assessment of each existing masonry bridge under static and dynamic loading conditions. A reliable structural assessment of old masonry arch bridges is, however, a very complex task. Spatial geometric consistency, assignment of proper mechanical properties and the need to consider several load combinations, associated to all possible positions of train loading, are important requirements for performing a reliable numerical model. The use of ‘General purpose’ three-dimensional nonlinear Finite Element (FEM) software, although accurate, is extremely time consuming in terms of model implementation and computational effort and requires expert judgement. In this paper a Discrete Macro-Element Method (DMEM) approach, previously applied to model the behaviour of different masonry structural typologies, is applied for the structural assessment of a masonry bridge. The computational cost of the proposed numerical approach is greatly reduced in comparison to that involved in nonlinear FEM simulations or Discrete Element Method (DEM) strategies based on a meso-scale discretisation. The discrete DMEM approach is applied for the structural assessment of a particular masonry arch bridge characterised by larger central span about twice the size of the other identical arches. The results show how the proposed DMEM can be successfully used for performing the structural assessment of masonry bridge with a reduced computational burden, compared to the nonlinear finite element simulations, and an easy and straightforward interpretation of the numerical results. © 2020, University of Cantabria - Building Technology R&D Group.

Corrosion-induced damage in aging bridge columns subjected to service loads can lead to significant reduction in their structural capacity and premature failure. This research presents a 3D numerical model using ABAQUS software to evaluate the structural response of large-scale RC columns subjected to eccentric load and reinforcement corrosion. The 3D numerical model evaluates and predicts RC structural behaviour for two different patterns of corrosion exposure: (i) corrosion of two ties at the mid-section of the column with cover stiffness reduction, (ii) corrosion in the compression rebar and cover stiffness reduction. The numerical model is validated with experimental work conducted on smallscale RC columns at the University of China. Results of the models are analyzed in terms of concrete and reinforcement response in addition to the lateral displacement at the mid-section of the column. © 2020, University of Cantabria - Building Technology R&D Group.

The method is applied on designing of the power transformer for a full bridge dc-dc converter used for power conversion in an automotive application. The dc-dc converters used in automotive applications must ensure stable and reliable operation in extreme operating conditions like wide input/output voltage range and elevated temperatures. Improper design of transformer may lead to poor converter performance and thermal issues which may require additional design iterations. The best approach is to construct a virtual prototype of the transformer. Thus, it can be used to perform simulations and optimizations until the desired performance is reached.

The same identification proves very challenging when nonstationary vibrations are measured as a train traverses the bridge. Despite the numerous attempts, nonstationary signals with low modulating frequencies are still difficult to be processed. This paper attempts to evaluate the bridge-vehicle first bending resonance by a method known as Wavelet Synchro-Squeezed Transform (WSST). The significant advantage of this signal processing method is to deal with low-frequency modulations, which are typical of long bridges. This research focusses on a Finite Element Model (FEM) of a bridge simulating the nonstationary vibration responses exerted by a spring-mass model traversing the bridge. The paper sets two objectives, and the first one is to investigate how the WSST analyses nonstationary signals generated by the FE model. The instantaneous frequency trace of the bridge-vehicle system will be compared to a similar frequency trace, that is created by performing several modal analyses at different locations of the bridge. The second objective of the paper is to investigate if the instantaneous frequency obtained from WSST is suitable for damage detection, as the FE model is fitted with damages. Both objectives are met, and the results will be presented. The trace of the first natural frequency matches well the one calculated by the WSST, and the instantaneous frequency shows to be capable of detecting damages included in the model. © 2020 European Association for Structural Dynamics.

Besides being a common part of the cultural heritage, many of them are still in service. As an example, we can cite the case of riveted bridges, railway stations, exhibition pavilions, or industrial buildings. The maintenance of these ancient constructions is crucial since they are prone to have suffered significant damage over time due to effects such as corrosion, human actions, or the exposure to heavy loads for which they were not originally conceived. Further, in many cases, these steel structures have to be strengthened in order to adapt them to new uses. HBIM (Historical Buildings Information Modeling) is a new methodology in structural design and construction that could be used as the ideal tool for the maintenance management of these historical structures. HBIM technology is adopted in this paper for structural engineering purposes. Departing from the geometric survey carried out by terrestrial laser scanning, a 3D model is obtained which apart of gathering the main dimensions and details regarding the composition of the structure, it allows collecting all the information concerning the deterioration grade or the different inspections and retrofitting actions performed over time. Thus, by introducing different time stages in the 3D model, the evolution of the structural health over time can be analyzed, which allows the decision-making regarding maintenance and, if required, the undertaking of repairing works. The proposed methodology will be applied to the case study of the Lapela Bridge, in Portugal. © 2020, Avestia Publishing.

Webb School of Construction, Arizona State Univ., Tempe, AZ, United States","Inspection on curved continuous rigid frame bridges (CRFBs) is necessary but challenging due to the complexity of bridge structures. Revealing the ""true""condition of CRFBs requires accurate field observations and reliable interpretation method to interpret the observed spatial changes. Non-contact vision-based systems (e.g., LiDAR) offer a promising alternative for structure change detection. Unfortunately, appropriate interpretations of the detected changes of CFRBs is challenging due to coupling deformations of connected bridge elements. Unreliable interpretations of change correlations of bridges can profoundly affect the effectiveness of maintenance planning. Finite element models (FEMs) developed based on the as-designed conditions could help explain how structural changes influence each other. Updating parameters of FEMs could simulate how deteriorations of structural elements influence the patterns of correlated structural changes. Unfortunately, FEM updating can be a multiple-solution problem - multiple possible structural properties and boundary conditions could produce similar geometric shapes of the structure under the same loading condition. In many cases, the combinations of FEM parameter values that form the solution search space can be exponentially large. Examining the exponentially large number of combinations of FEM parameter updates is computationally intractable for large structural systems. As a result, existing studies that use field data for updating FEM and interpreting structural changes could only handle structures with a few elements in controlled environments. This study established a method for FEM updating based on vision-based correlated change analysis. The method focuses on integrated used of change correlation analysis and FEM simulations for reducing the computational complexity. The results indicate that the correlated change analysis provides the potential of eliminating possibilities of certain combinations when updating the FEM for improved computational efficiency. © 2020 American Society of Civil Engineers.",,"Computational efficiency; Rigidity; Structural analysis; Structural properties; Sustainable development; Controlled environment; Correlation analysis; Curved continuous rigid-frame bridges; Finite-element model updating; Interpretation methods; Maintenance planning; Non-contact visions; Solution-search space; Finite element method",,,,,,,,,,,,,,,,"Castellazzi, G., D'Altri, A.M., Bitelli, G., Selvaggi, I., Lambertini, A., From laser scanning to finite element analysis of complex buildings by using a semi-automatic procedure (2015) Sensors (Switzerland), 15 (8), pp. 18360-18380; Chen, H., Zheng, S., Seismic response of ultra high-pier railway bridge under spatially varying site conditions of earthquake excitations (2015) Journal of Highway and Transportation Research and Development, 9 (2), pp. 61-68; Conte, J.P., Zhang, Y., Performance based earthquake engineering: Application to an actual bridge-foundation-ground system (2007) 12th Italian National Conference on Earthquake Engineering, pp. 1-18. , Pisa, Italy; Feng, J., Dong, J., (2014) Study on the Seismic Behavior of the Large-Span, Curved, Continuous, Rigid Frame Bridge under Different Curvature Radius.; Holland, J.H., (1975) Adaptation in Natural and Artificial Systems: An Introductory Analysis with Applications to Biology, Control, and Artificial Intelligence, , Ann Arbor University of Michigan Press; Kasireddy, V., Akinci, B., Challenges in generation of as-is bridge information model: A case study (2015) 32nd International Symposium on Automation and Robotics in Construction; Kirkpatrick, S., Gelatt, C.D., Vecchi, M.P., Optimization by simulated annealing (1983) Science; Li, X., Li, Z.X., Crewe, A.J., Nonlinear seismic analysis of a high-pier, long-span, continuous rc frame bridge under spatially variable ground motions (2018) Soil Dynamics and Earthquake Engineering, 114, pp. 298-312. , Elsevier Ltd April 2017; Pan, Z., Fu, C.C., Jiang, Y., Uncertainty analysis of creep and shrinkage effects in long-span continuous rigid frame of sutong bridge (2011) Journal of Bridge Engineering, 16 (2), pp. 248-258; Posenato, D., Lanata, F., Inaudi, D., Smith, I.F.C., Model-free data interpretation for continuous monitoring of complex structures (2008) Advanced Engineering Informatics, 22 (1), pp. 135-144; Raphael, B., Smith, I.F.C., (2003) Global Search through Sampling Using A PDF.; Sun, Z., Shi, Y., Xiong, W., Tang, P., Knowledge-based registration for reliable correlated change detection on high-pier curved continuous rigid frame bridge (2019) EG-ICE 2019 Workshop on Intelligent Computing in Engineering; Sun, Z., Tang, P., Shi, Y., Xiong, W., Visual-semantic alignments for automated interpretation of 3D imagery data of high-pier bridges (2019) Proceeding of the 2019 ASCE International Conference On.

To reduce this conservatism, the ASME WG-EFEM has proposed the development of an improved assessment methodology for environmental fatigue based on a Total Life Prediction approach that would be adequately, but not excessively, conservative. Such an approach necessitates the development of analytical methods for the various stages of crack nucleation, short crack growth and long crack growth. Hence, there is a requirement to undertake testing within the short crack growth regime that would bridge the gap between fatigue nucleation and long crack growth (Paris Law) enabling better prediction of total life measured by fatigue endurance. A test methodology has been developed by Wood to enable short crack growth testing with in-situ monitoring using DCPD. Testing has been undertaken in both high temperature air (300ºC) and simulated end-of-cycle primary water chemistry at 300ºC on cold-worked stainless steel specimens, which were subject to a range of load ratios and rise times. FEA modelling has been undertaken to determine the effective stress intensity factors applied under the loading conditions based on the specific material properties. This paper presents the results from a testing program conducted with EPRI, to measure fatigue crack growth data for short cracks from 0.15 mm to 1.0 mm. Crack growth rates have been compared to those predicted in ASME, Code Case N-809 and results from material specific in-house testing to assist the understanding of the behaviour of mechanically short cracks. © 2020 ASME","Corrosion; Fatigue; Metals; Reactor/Nuclear; Structural Integrity; Testing","Austenitic stainless steel; Crystallization; Fatigue crack propagation; Fatigue testing; Nucleation; Plastic deformation; Pressure vessels; Software testing; Steel research; Stress analysis; Thermal fatigue; Assessment methodologies; Effect of environments; Effective stress intensity factor; Environmental fatigue; Fatigue endurances; High temperature air; In- situ monitoring; Short crack growth; Cracks",,,,,"Electric Power Research Institute, EPRI","The authors gratefully acknowledge the financial support from the Electric Power Research Institute Inc for the funding of this project.",,,,,,,,,,"Chopra, O., Shack, W.J, (2007) Effect of LWR Coolant Environments on the Fatigue Life of Reactor Materials, , U.S. Nuclear Regulatory Commission.

In order to solve the difficulty of cleaning the debris at the bottom of the well, a kind of wellbore cleaning tool is proposed based on the principle of negative jet pressure and liquid-solid two-phase flow theory. e finite element analysis method and laboratory test were used to verify the function of cleaning tools: The finite element method can effectively reflect the principle and process of dredging bottom debris with cleaning tools. In order to improve the applicability and fishing ability of wellbore cleaning tools, factors influencing the performance of cleaning tools were analyzed as follows: Choosing high-density and low-viscosity working fluid is beneficial to improve the negative pressure effect of cleaning tools. Under the conditions of wellbore safety and economy, increasing pump pressure and displacement and reducing annular pressure can effectively increase the fishing performance of cleaning tools.

A phase shift control dual active bridge converter base on integrated magnetics is proposed, in which one transformer and one inductor are integrated in an EE core. The size of the inductance can be accurately controlled. The transformer and the inductor are decoupled and integrated so that the two operating states do not affect each other. The weight and volume of the magnetic elements are reduced accordingly. The finite element analysis and magnetic circuit simulation of the integrated magnetics are carried out.

Design/methodology/approach: To achieve the purpose of this study, a thermal-elastic-plastic finite element (TEP FE) model is developed to analyze the thermal-mechanical behavior of the T-welded joint during the welding process. Experimental measurements have verified the validity of the established TEP FE model. Using the effective model, a series of numerical experiments are performed to obtain the inherent deformations under the conditions of different influencing factors, and then the calculation results are discussed based on the relevant data obtained. Findings: Through numerical simulation analysis, it is found that the longitudinal and transverse inherent deformations decrease with the increase of welding speed and plate thickness, whereas as the nominal heat input increases, the inherent deformations increase significantly. The longitudinal shrinkage presents a quasi-linear and nonlinear distribution in the middle and end of the weld, respectively. The plastic strains in the cross section of the T-joint also vary greatly because of the process parameters and plate thickness, but the maximum value always appears near the location of the welding toe, which means that this point faces a relatively large risk of fatigue cracking. The inherent deformations are closely related to the plastic strains remaining in the weld zone and are also affected by many influencing factors such as process parameters and plate thickness. Research limitations/implications: In this study, relatively few influencing factors such as welding current, voltage, speed and plate thickness are considered to analyze the inherent deformations in the T-welded joint. Also, these influencing factors are all within a certain range of parameters, which shows that only limited applicability can be provided. In addition, only in-plane inherent deformations are considered in this study, without considering the other two out-of-plane components of inherent deformations. Originality/value: This study can help to expand the understanding of the relationship between the inherent deformations and its influencing factors for a specific form of the welded joint, and can also provide basic data to supplement the inherent deformation database, thereby facilitating further researches on welding deformations for stiffened-panel structures in shipbuilding or steel bridges. © 2020, Emerald Publishing Limited.","Finite element method; Influential factors; Inherent deformations; Process parameters; T-joint fillet weld; Welding experiment","Elastoplasticity; Plastic deformation; Plates (structural components); Structural panels; Thermal fatigue; Welded steel structures; Welding; Design/methodology/approach; Elastic-plastic finite element; Longitudinal shrinkage; Non-linear distribution; Numerical simulation analysis; Out-of-plane components; Stiffened panel structures; Thermal-mechanical behavior; Welds",,,,,"National Natural Science Foundation of China, NSFC: 51708346","The authors would like to thank the support from the National Natural Science Foundation of China under Grant no. 51708346.",,,,,,,,,,"Atabaki, M.M., Nikodinovski, M., Chenier, P., Ma, J., Liu, W., Kovacevic, R., Experimental and numerical investigations of hybrid laser arc welding of aluminum alloys in the thick T-joint configuration (2014) Optics and Laser Technology, 59, pp. 68-92; Brickstad, B., Josefson, B.L., A parametric study of residual stresses in multi-pass butt-welded stainless steel pipes (1998) International Journal of Pressure Vessels and Piping, 75 (1), pp. 11-25; Chen, B.Q., Soares, C.G., Effects of plate configurations on the weld induced deformations and strength of fillet-welded plates (2016) Marine Structures, 50, pp. 243-259; Chen, Z., Chen, Z., Shenoi, R.A., Influence of welding sequence on welding deformation and residual stress of a stiffened plate structure (2015) Ocean Engineering, 106, pp. 271-280; Deng, D., Murakawa, H., FEM prediction of buckling distortion induced by welding in thin plate panel structures (2008) Computational Materials Science, 43 (4), pp. 591-607; Deng, D., Murakawa, H., Shibahara, M., Investigations on welding distortion in an asymmetrical curved block by means of numerical simulation technology and experimental method (2010) Computational Materials Science, 48 (1), pp. 187-194; Deng, D., Murakawa, H., Liang, W., Numerical simulation of welding distortion in large structures (2007) Computer Methods in Applied Mechanics and Engineering, 196 (45-48), pp. 4613-4627; Deng, D., Liang, W., Murakawa, H., Determination of welding deformation in fillet-welded joint by means of numerical simulation and comparison with experimental measurements (2007) Journal of Materials Processing Technology, 183 (2-3), pp. 219-225; Deng, D., Murakawa, H., Liang, W., Prediction of welding distortion in a curved plate structure by means of elastic finite element method (2008) Journal of Materials Processing Technology, 203 (1-3), pp. 252-266; Deng, D., Sun, J., Dai, D., Jiang, X., Influence of accelerated cooling condition on welding thermal cycle, residual stress, and deformation in SM490A steel ESW joint (2015) Journal of Materials Engineering and Performance, 24 (9), pp. 3487-3501; Deng, D., Kiyoshima, S., Ogawa, K., Yanagida, N., Saito, K., Predicting welding residual stresses in a dissimilar metal girth welded pipe using 3D finite element model with a simplified heat source (2011) Nuclear Engineering and Design, 241 (1), pp. 46-54; Fu, G., Lourenço, M.I., Duan, M., Estefen, S.F., Influence of the welding sequence on residual stress and distortion of fillet welded structures (2016) Marine Structures, 46, pp. 30-55; Huang, H., Wang, J., Li, L., Ma, N., Prediction of laser welding induced deformation in thin sheets by efficient numerical modeling (2016) Journal of Materials Processing Technology, 227, pp. 117-128; Jung, G.H., Tsai, C.L., Fundamental studies on the effect of distortion control plans on angular distortion in fillet welded T-joints (2004) Weld.

Cold-formed square hollow cross-sections of steel grade S355J2H with dimensions 80 mm × 4 mm, 90 mm × 4 mm and 40 mm × 4 mm were selected for the top and bottom chords and bracing elements of the truss with 12.56 m span, correspondingly. Five FEM models were developed using software Dlubal RFEM. The main specific feature of the models is the difference in modelling of joint behaviour considering plastic behaviour and stiffness of truss connections. It was shown that the FE model of the truss where the members were modelled by the truss type finite elements and the joints modelled by the shell type ones allows predicting behaviour of the truss with precision of up to 3.9%. It was shown that precision of the suggested FEM model grows 4.36 to 4.62 times in comparison with the traditional FEM models where the members were modelled by the truss finite elements with the pinned and rigid joints in case of plastic joint behaviour. Precision of the suggested FEM model is identical to that of the traditional FEM models regarding the case of elastic joint behaviour. © 2020 The Author(s).

However, the degrees of freedom in the dimensioning of these metal substrates with regard to area, thickness, symmetry and chip positioning are large and optimization towards minimum thermal resistance results in unnecessarily large and unmanufacturable leadframes with high parasitic inductance, which hinders fast switching. In this paper the influence of geometric parameters of the leadframe on the thermal performance is investigated based on thermostatic 3D FEM simulations of a half-bridge with symmetrical losses.

Static analysis results showed that the straight model had the minimum values of static internal forces. Therefore, this model gave higher resistance to effects of applied loads and the horizontal layout straight of this type of bridges was suitable for design. © 2006-2020 Asian Research Publishing Network (ARPN).","Box girder; Bridge; Dynamic; Finite element; Horizontal layout; Static",,,,,,,,,,,,,,,,,"Naser, A.F., Lin, W.Z., Damage Monitoring and Field Analysis of Dynamic Responses of HaShuang Prestressed Concrete Box Girder Oblique Bridge before Strengthening (2011) Advanced Materials Research, 255-260, pp. 1102-1106; Chassiakos, A.P., Vagiotas, P., Theodorakopoulos, D.D., A knowledge-based System for Maintenance Planning of Highway Concrete Bridge (2015) Advances in Engineering Software, 36, pp. 740-749; Kanth, S.N., Prasad, V.A., Design and Analysis of Bridge Design Using Staad pro (2015) International Journal of Research Sciences and Advanced Engineering, 2 (12), pp. 211-224; Balasubramanian, A., Bridges and Their Types (2017), https://www.researchgate.net/publication/315662977_Bridges_and_their_Types, Technical Report, Centre for Advanced Studies in Earth Science, University of Mysore, Mysore; Troitsky, M.S., (1994) Planning and Design of Bridges, , John Wiley & Sons, INC, Canada; Arthur, H., (1987) Design of Pre-Stressed Concrete, p. 592. , 2nd Edn, Wiley, New York, USA; Lian, D., (2008), Highway Bridges, McGraw-Hill's Access Science; Fundamentals of Pre-Stressed Concrete Design (1968), p. 133. , 2nd Edn.

In this study, based on the numerical simulation, finite element analysis was carried out on the concrete T beam through the ANSYS software, and the selection of elements and the constitutive relationship of materials in the numerical simulation were introduced. It was found from the results of numerical simulation that the cracks of T beam continued to develop under the action of load, the concrete entered the plastic state from the elastic state and the mid-span deflection increased with the increase of load. In the case of the change of cracks, the larger the crack height, the larger the crack range of the beam. With the increase of load, the structural rigidity continued to degenerate, and the compressive stress of the concrete also increased. The research in this paper proves the validity of numerical simulation in the study of nonlinear mechanics of beam bridge and also makes some contributions to the study of crack damage of beam bridge. © 2020, North Atlantic University Union.

Using nonlinear dynamic time history analysis method, the seismic mitigation performance of the bearings on high-speed railway bridges is studied. The parameters of the seismic isolation bearing, including the friction coefficient of the sliding surface and the radius of curvature, are optimized. Numerical analysis results show that: (1) Hyperboloid spherical seismic isolation bearings provide very good mitigation effect. (2)The bending moment at the bottom of the main pier and the displacement of the pier top both decrease first and then increase with the increase of the friction coefficient. The shear force at the bottom of the pier and the pier-beam relative displacement both decrease with the increase of the friction coefficient; The internal forces of the side pier bottom, the displacement of the pier top and the relative pier-beam displacement both decrease with the increase of the friction coefficient. (3)The internal force and the top displacement of each pier have a tendency to increase slowly with the increase of the radius of curvature. The change value is not obvious, and the pier-beam relative displacement increases with the increase of the radius of curvature. The bearing parameters should be determined both on the numerical analysis results and the requirements of the bearing structure size. © 2020 IEEE.","Continuous girder bridge; Friction coefficient; High-speed railway; Hyperboloid spherical seismic isolation bearing; Optimization; Radius of curvature","Bearings (structural); Big data; Curve fitting; Friction; Piers; Railroad bearings; Railroads; Seismology; Smart city; Spheres; Continuous girder bridge; Friction coefficients; High - speed railways; High-speed railway bridges; Nonlinear dynamic time-history analysis; Radius of curvature; Relative displacement; Seismic isolation bearings; Railroad transportation",,,,,,,,,,,,,,,,"Zhuang, J.-S., (2012) Bridge Isolation Bearings and Devices [M], , Beijing: China Railway Publishing House; Penu, T.-B., Li, J.-Z., Fan, L.-C., Development and application of double spherical aseismic bearing[J] (2007) Journal of Tongji University (Natural Science Edition), 35 (2), pp. 176-180; Xu, Y.-Q., Seismic analysis on long continuous unit and multi-span bridge &research on seismic mitigation and isolation application[J] (2016) Special Structures, 33 (1), pp. 53-61; Zheng, X.-L., Jin, Y.-X., Design and seismic isolation performance analysis of friction pendulum bearings[J] (2014) Journal of Railway Engineering Society, (4), pp. 81-87; Gu, Z.-W., Zhong, T.-Y., Zhang, Z.-G., Seismic isolation of curved continuous bridge with double spherical aseismic bearing[J] (2011) China Railway Science, 32 (3), pp. 47-51; Jiao, C.-Y., Hu, S.-D., Guan, Z.-G., Comparison study on analysis models of fps seismic isolation support[J] (2007) Journal of Vibration and Shock, 26 (10), pp. 1l3-117; Wei, B., Liu, Y.-W., Jiang, L.-Z., He, W.-K., Fu, Y.-J., Dynamic behaviors of double spherical isolation bearing in simply-supportedrailway bridges under earthquakes[J] (2019) China Civil Engineering Journal, 52 (6), pp. 1l0-118; Zhan, Y.-L., Zhang, L., Zhang, Q., Jiang, Z.-X., Effects of parameters of friction pendulum bearings on seismic responses of seismically isolated bridge[J] Bridge Construction, 2018vol, 48 (3), pp. 45-49; Li, Y., Yu, L.-S., Xia, X.-S., Optimal placement of the viscous dampers combined with double spherical seismic bearings in large span continuous girder bridge[J] (2018) Journal of Railway Science and Engineering, 15 (11), pp. 2867-2874; Murat, E., Reginald desrochesjhe influence of design parameters on the response of bridges seismically isolated with the friction pendulum system(fps)[J] (2013) Engineering Structures, 56, pp. 585-599","Quan, W.; School of Architecture and Civil Engineering, China; email: 24633047@qq.com",,,"Institute of Electrical and Electronics Engineers Inc.","2020 International Conference on Intelligent Transportation, Big Data and Smart City, ICITBS 2020","11 January 2020 through 12 January 2020",,160946,,9781728166971,,,"English","Proc. - Int.

In addition, through the lever principle formed by three auditory ossicle structure, the sound was concentrated and amplified to the inner ear. However, the sound transmission function of the middle ear will be decreased by disease, genetic, or trauma. Hence, using middle ear prosthesis to replace the damaged ossicles can restore the conduction function. The function realization of middle ear prosthesis depends on the vibration response of the prosthesis from the tympanic membrane to the stapes plate on the human auditory perception frequency, which is affected by the way the prosthesis combined with the tympanic membrane, the material, and the geometric shape. In this study, reasonable prosthetic structures had been designed for different types of ossicular chain injuries, and the frequency response characteristics were analyzed by the finite element method then. Moreover, in order to achieve better vibration frequency response, a ball structure was designed in the prosthesis to simulate its amplification function. The results showed that the middle ear prostheses constructed by different injury types can effectively transfer vibration energy. In particular, the first- and second-order resonant frequencies and response amplitudes are close to each other when ball structure models of different materials are added. Instead, the resonance frequency of the third stage formed by aluminum alloy ball materials is larger than that of the other two, which showed good response features. © 2020 Wu Ren et al.",,"Aluminum alloys; Architectural acoustics; Audition; Frequency response; Natural frequencies; Structural design; Vibrations (mechanical); Amplification functions; Auditory perception; Frequency response characteristic; Resonance frequencies; Response amplitudes; Vibration characteristics; Vibration frequency; Vibration response; Prosthetics; aluminum; titanium; Article; auditory ossicle; auditory system function; biomechanics; device comparison; ear injury; energy transfer; finite element analysis; frequency; human; middle ear; middle ear deafness; priority journal; prosthesis design; prosthetic replacement; simulation; vibration",,"aluminum, 7429-90-5; titanium, 7440-32-6",,,,,,,,,,,,,,"Katilmis, H., Songu, M., Aslan, H., Ozkul, Y., Basoglu, S., Kulduk, E., Eren, E., Alqahtani, A., Outcomes with gold wire and hydroxyapatite partial ossicular replacement prostheses in type 2 tympanoplasty: A preliminary study (2015) Journal of Laryngology and Otology, 129 (2), pp. 142-147. , 2-s2.0-84923553372 25695277 Total ossicular replacement prosthesis of the middle ear: a biomechanical analysis Journal of Mechanics in Medicine and Biology 2015 15 2 10.1142/S0219519415400060 2-s2.0-84928389803 Effect of bacterial biofilm on hearing restoration with titanium partial ossicular prosthesis replacement Journal of Medical Biomechanics 2015 30 3 238 242 First results of a novel adjustable-length ossicular reconstruction prosthesis in temporal bones Laryngoscope 2016 126 11 2559 2564 10.1002/lary.25901 2-s2.0-84960924679 26972795 Long term results of the titanium clip prosthesis European Archives of Oto-Rhino-Laryngology 2016 273 12 4257 4266 10.1007/s00405-016-4174-3 2-s2.0-84976427933 27356555 Long-term results of the cartilage shoe technique to anchor a titanium total ossicular replacement prosthesis on the stapes footplate after type III tympanoplasty JAMA Otolaryngology-Head & Neck Surgery 2016 142 11 1094 1099 10.1001/jamaoto.2016.2118 2-s2.0-84997283855 27541000 Parameters for novel incus replacement prostheses European Archives of Oto-Rhino-Laryngology 2016 273 9 2411 2417 10.1007/s00405-015-3810-7 2-s2.0-84946140363 Finite element simulation of human ears Noise And Vibration Control 2016 36 2 61 64 Research on middle ear mechanics Chinese Journal of Otology 2016 14 3 353 359 Dynamics of the middle ear ossicles with an SMA prosthesis International Journal of Mechanical Sciences 2017 127 163 175 10.1016/j.ijmecsci.2016.10.004 2-s2.0-85006115569 Surgical reconstruction of the ossicular chain with custom 3D printed ossicular prosthesis 3D Printing in Medicine 2017 3 1 7 10.1186/s41205-017-0015-2 29782607 Systematic review of ossicular chain anatomy: strategic planning for development of novel middle ear prostheses Otolaryngology and Head and Neck Surgery 2017 157 2 190 200 10.1177/0194599817701717 2-s2.0-85026764071 28463590 Anatomical and functional results of ossiculoplasty using titanium prosthesis Acta Otorhinolaryngologica Italica 2018 38 4 377 383 10.14639/0392-100X-1700 2-s2.0-85051371724 30197429 Total ossicular replacement prosthesis: a new fat interposition technique Clinical Medicine Insights: Ear, Nose and Throat 2018 11 8 10.1177/1179550617749614 The benefit of trans-attic endoscopic control of ossicular prosthesis after cholesteatoma surgery The Laryngoscope 2019 129 12 2754 2759 10.1002/lary.27848 2-s2.0-85061044897","Ren, W.; School of Medical Engineering, China; email: renwu88@126.com",,,"Hindawi Limited",,,,,11762322,,,,"English","Appl.

The process includes an initial phase of geotechnical and structural investigations, used to evaluate the minimum risk indicator among all the possible collapse mechanisms of each bridge, by specific analyses. In particular, the structural capacity is assessed by kinematic analyses for simple single span bridges otherwise by pushover analyses applied to 3D FEM models. After that, for those structures that show a lower structural capacity than the seismic demand defined by the Italian standards, the seismic improvement intervention is designed, considering the usage requirements of the Infrastructure. © Springer Nature Switzerland AG 2020.","Masonry arch bridges; Non-linear analysis; Seismic capacity",,,,,,,,,,,,,,,,,"(2003) Ordinance N. 3274 Initial Elements on the General Criteria for Classifying National Seismic Zones and Technical Standards for Constructions, , Official Gazette of the Italian Republic, no. 105; (2018) Update of the Technical Standard for Constructions, , Official Gazette of the Italian Republic, no. 42; Circular 21/01/2009, No. 7.

Although these innovative bridges present several advantages in terms of cost and structural performance with respect to the conventional tied-arch bridges, they remain vulnerable under certain loading condition. Indeed, due to the large compressive force that may arise in steel arches of the bridge under service, they are prone to deflect out of his plane resulting in the degradation of the aesthetic aspect often praised of bridges of this type and later its service disablement. For this reason, the lateral behaviour of such kind of bridges should be investigated carefully. In this study, lateral structural response of network arch bridges against traffic loads has been analyzed through extensive non-linear analyses. Firstly, a calibration is useful to validate the numerical model. Then, initial geometric imperfections are assigned to the arch member before the analysis in order to take into consideration defects from the manufacturing process. Finally, non-linear analyses are performed on a full 3D numerical model to capture the behaviour of the arch bridge. The results showed that the lateral displacement of the arch member increase with the increase of the traffic loads up to a certain value. In addition, it is observed that the lateral arch’s bracing changes the development of plastic hinges in the arch. © Springer Nature Switzerland AG 2020.","Finite element analysis; Out of plane buckling; Vertical loads",,,,,,,,,,,,,,,,,"Tveit, P., The design of network arches (1966) Struct.

This paper proposes a reinforcement method by adding cable tower at the two ends abutments of the arch bridges and the inclined cables to improve behavior of the multi-rib arch bridge. The main idea is that additional bridge towers are set on both sides of the single span ribbed arch bridge abutment to hang stayed cables. Taking a typical reinforced concrete multi-rib arch bridge-Baibu Bridge as engineering background, the design of strengthening project was given. The analysis and field load test of the bridge were finished. The comparison between spatial finite element analysis results and field bridge test values of strengthened bridge has good agreement.

The United Kingdom, with most of its motorway network having been built during the 1960s, is a typical example of this. This paper focuses on the inspection and detailed structural assessment that Mott Macdonald’s A3M (Advanced Analysis for Asset Management) team was commissioned to undertake on this rather unique reinforced concrete arch bridge. With a total span of circa 50 m and built in 1968, this arch bridge is located in an area of outstanding natural beauty in South Wales and presently owned and managed by a Water Company. Aspects relating to the inspection and survey techniques employed, such as point cloud surveys derived from site laser scans and live load monitoring using wireless strain gauges are covered in detail in the first part of the paper. The second part of the paper focus on the aspects related to the static and dynamic modelling of the structural behaviour of the bridge using the finite element method emphasizing some of the techniques developed by the authors to establish comparisons between the experimental and numerical results.

Some of their component elements such as bridge approaches, inclined parking ramps and stadium beams are exposed to a simultaneous combination of high axial loads and bending moments. A relatively new solution for heavily loaded composite members are concrete-filled tubular flange girders (CFTFGs) which are unconventional I-shaped girders where one or both of the steel flanges are replaced with a hollow section and then filled with concrete to increase the strength and stiffness. These are complex members and their behaviour is governed by a number of inter-related parameters. This work aims to investigate the ultimate strength of CFTFGs with a stiffened web under the combined effects of various levels of axial tension and positive (sagging) bending moment. Nonlinear three-dimensional finite element (FE) analyses using the ABAQUS computer software package are employed to conduct parametric studies. Several influential parameters are examined and conclusions are discussed.

The experimental and theoretical results were compared in an example of loading the control section. The stress value of the cable tension area of the main beam upper edge was found to markedly change when tensiling the cable force and was accompanied by prominent shear lag effect. After a hanging basket load was applied, the main beam of certain sections showed alternating positive and negative shear lag characteristics. The shear lag distribution law in the box girder of the single-cable-plane prestressed concrete cable-stayed bridge along the longitudinal direction was determined in order to observe the stress distribution of the girder. The results show that finite element analysis of the plane bar system should be conducted at different positions in the bridge under construction; the calculated shear lag coefficient of the cable force acting at the cable end of the cantilever reflects the actual force. In the beam segments between the cable forces, the shear lag coefficient determined by the ratio of the bending moment to the axial force reflects the actual stress at the cable force action point. In the midspan beam section between the action points of cable forces, the shear lag coefficient of the bending moment reflects the actual stress. The section shear lag coefficient can be obtained by linear interpolation of the beam section between the cable action point and the middle of the span. © 2020 Yan-feng Li et al.",,"Beams and girders;

This paper presents the procedure followed during the analysis and design process of a pile supported fender system protecting a new major multi span bridge with several piers in the waterway. The design of any fender system is an iterative process based on energy absorption as per AASHTO specifications. In this case the total kinetic energy for the impact was calculated based on the vessel parameters to be a total of 44,200 kip-ft. There are two approaches used for the design of these fender systems: one is based on strength and the other is based on ductility. In the strength design method, the impact force is resisted while keeping the structural elements within the material elastic range limiting any permanent structural damage and deformation. This results in insignificant system deflections. The other procedure takes advantage of the ductility of the system to absorb the impact energy by allowing material yielding to occur while maintaining global stability. Since the fender system is designed as a sacrificial system, a decision was made to go with the ductility design approach to achieve considerable construction cost savings. A finite element analysis model (FEM) is developed using ANSYS APDL software. In this model, the piles are modeled using 3D beam line elements supported on non-linear spring elements representing the soil (Beam on Winkler foundation). The spring behavior is derived using Ensoft L-PILE analyses. This method of representing the soil is used instead of the computationally demanding solid continuum elements that require sophisticated calibrated material models. The FEM considers the full non-linear stress-strain behavior of steel, P-delta effects, pile-soil interaction, and global buckling of the piles. Local buckling analysis is also performed separately and explained in detail throughout the paper. After validating the single pile model with L-PILE, a full FEM model for the entire fender system is built. Push over analysis is performed and the total energy absorbed is calculated by integrating the area under the load-deflection curve. Different load cases are considered for different impact angles and vessel speeds. The performance acceptance criterion of the system is established to ensure that enough energy is absorbed to avoid any contact between the fender system and the bridge pier under vessel collision loading. To reduce P-delta effects, the final design is comprised of a hollow pre-cast 12 ft x 12 ft box pile cap supported on twelve 48 inch diameter 1.5 inch thick steel piles filled with low grade concrete to prevent the piles' local buckling. This paper also addresses the structural detailing aspects implemented to ensure satisfactory performance of the system in the post yield stage. Construction challenges associated with the erection of this system is also discussed. © 2020 American Society of Civil Engineers.",,"Bridges; Buckling; Ductility; Fenders (boat); Iterative methods; Kinetic energy; Kinetics; Offshore structures; Piers; Soils; Structural analysis; Acceptance criteria; Finite element analysis model; Integral components; Load-deflection curve; Non-linear stress-strain behavior; Pile soil interaction; Structural analysis and designs; Total kinetic energy; Piles",,,,,,,,,,,,,,,,"(2018) Ansys mechanical APDL structural analysis, release V19.1, , http://www1.ansys.com, ANSYS Inc; (2014) American Association of State Highway and Transportation Officials, , AASHTO LRFD Bridge Design Specifications; Crawford, S.F., Kulak, G.L., (1968) Behavior of Eccentrically Loaded Bolted Connections, Studies in Structural Engineering, Department of Civil Engineering, , The university of Texas at Austin, Austin; (2011) LPILE v6.0: A program for the analysis of piles and drilled shafts under lateral loads, , Ensoft Inc.

However, the safety of steel bridges is influenced by the fatigue performance of welded details. So, cope-hole details with flange and web subjected to axial loads were selected as the research object. Based on the basic theory of linear elastic fracture mechanics and the Finite Element Method, the stress intensity factors of cope-holes details were calculated. The influences of geometry size and crack size of the detail on the stress intensity factors were then investigated. The Paris model of fatigue crack propagation predicted the crack propagation life of cope-hole details. Besides, the fatigue limit-state equation was also established to analyse the effect of random variables (such as initial crack size, critical crack size, crack propagation parameter) on the fatigue reliability index. Finally, the recommended value of the detection period was present. The results show that the stress intensity factor gradually increases with the increase of the cope-hole radius, the weld size, the flange plate thickness, the crack length and the web thickness. However, it gradually decreases with the increase of the ratio of the long and short axle to the crack. The predicted number of fatigue cyclic loading required by the fatigue crack depth propagating from 0.5 mm to 16 mm under nominal stress amplitude of 63 MPa is 122.22 million times. The fatigue reliability index decreases with the fatigue growth parameter, the crack shape ratio and the mean of initial crack size increasing, which is relatively sensitive. However, the variation coefficient of the initial crack size has little effect on it. The detection period of cope-hole details is the service time corresponding to the fatigue accumulated cyclic loading of 198.3 million times. © 2020 The Author(s).

As such, it becomes difficult for the beam and the slab to bear the force together. Moreover, the bearing capacity, rigidity, and integrity of the structure weaken. This study presents the experimental and shear stress calculation models of the T-beam formed by gluing the bridge deck and the rectangular beam together to improve the bearing capacity and rigidity of the structure and the overall mechanical performance of the beam and the slab. Two groups of six parallel glued T-beams were designed and manufactured using Larixgmelinii as raw material. The T-beam was reversed into an inverted T-beam, which was loaded in the middle of the span under the condition of simple support at both ends, so that the rib plate was compressed and the wing plate was tensioned. In this way, the mechanical performance of the negative bending moment of the supporting section of the continuous T-beam was simulated. Results of strain, deflection, flexural rigidity, ultimate bearing capacity, and ductility of the two groups of specimens were measured and analyzed. The failure mode and mechanism of glued wood beam were also observed and evaluated. The glued wood inverted T-beam model was established by the ABAQUS finite element software. Furthermore, the midspan deflection, measuring point displacement, strain, and failure mechanism of the component under the same load level were simulated and investigated, and the test results were verified. Results demonstrate that shear failure occurs along the grain of the beam. In comparison with those of group A, the yield load, yield displacement, ultimate bending capacity, ultimate displacement, flexural rigidity, and ductility coefficient of group B decrease by 9.7%, increase by 27.5%, decrease by 10.4%, increase by 42.7%, decrease by 36%, and increase by 22.4%, respectively. The unfavorable area of the shear stress of the simulated beam under the ultimate load coincides with the position where crack in the test beam developed. The deflection curve of midspan load and the transverse distribution curve of flange strain were in good agreement with each other. The deviation between the simulated and the test values of the midspan deflection and the maximum tensile compression strain did not exceed 15%.

To find the damage present in a system is becoming one of the important research topics in today’s civil and mechanical engineering field. This topic of research can mainly be used in bridges, offshore platforms, plates, shells, beams, aerospace and composite structures and other large civil structures to detect structural damages by analyzing the dynamic features of the system. It has been observed due to any slight physical change, the stiffness of the system changes which changes the modal responses of the system. The aim of this research work is to derive a simple method for estimating the failure parameters (crack depth and crack location) in structures based on a data-driven subspace identification technique. These changes in the modal parameters can be used as the input variables to find out the damage severity. The responses (natural frequencies) were obtained using finite element analysis, and then, the differential evolution algorithm (a type of evolutionary algorithm) is used to detect and characterize these defects. This work proposes a robust computational application of the differential evolution algorithm that more accurately takes into account the natural evolution with initial point and produces a good converging result. © 2020, Springer Nature Singapore Pte Ltd.","Damage; Differential evolution algorithm; Natural frequencies","Bridges; Cracks; Damage detection; Evolutionary algorithms; Modal analysis; Offshore oil well production; Optimization; Damage; Differential evolution algorithms; Dynamical parameters; Engineering fields; Machine element; Offshore composites; Offshore platform structure; Research topics; Rotating machine; Structural elements; Natural frequencies",,,,,,,,,,,,,,,,"Jaiswal, N.G., Pande, D.W., Sensitizing The mode shapes of beam towards damage detection using curvature and wavelet transform (2015) Int J Sci Technol Res, 4 (4), pp. 266-272; Tada, H., Paris, P.C., Irwin, G.R., (1973) The Stress Analysis of Cracks Handbook, , Del.

In this paper, a modelling approach that shows the healing potential of a blended cementitious system will be provided that consists of original cementitious particles mixed with so-called Dissoluble Encapsulated Particles (DEPs). DEPs are represented by a range of predefined fractions of original cementitious particles, but with its surface covered with a thin membrane. The self-healing principle of this system is based on the most basic healing process, where a delayed hydration of the DEP fractions may occur initiated by a crack. The crack actually triggers the membrane to open and exposes the still unhydrated DEP particles to water, after which the delayed hydration of the DEP system will take place, while closing the crack. The proposed model will demonstrate the healing potential of DEP inside a concrete and analyse the most dominant parameters affecting the mechanism. The membrane is considered to decapsulate by it's dissolution or cracking whenever being triggered by cementitious crack formation, which either lowers pH-conditions due increased CO2 ingress, or induces mechanical stresses. The results show the potential of the healing mechanism to bridge a certain crack width, and shows, which fractions of a regular cement should be replaced in order the DEP system being most efficient. The numerical predictions also show that multi fraction DEP systems are more efficient then single fraction DEP, and that the addition of DEP does not affect the properties but may lead to a delay in the property development of cementitious systems. copyright © Crown copyright (2018).All right reserved.","Cement; Cracking; DEP; Encapsulation; Micro-scale; Self-healing; X-FEM","Cements; Computational fluid dynamics; Computational mechanics; Crack initiation; Cracks; Encapsulation; Grading; Hydration; Self-healing materials; Sols; Cementitious systems; Colloidal suspensions; Mechanical stress; Micro-scale; Mineral particles; Numerical predictions; Property development; Self-healing; Suspensions (fluids)",,,,,"645704, ITA-1185040-HFST-P; Alexander von Humboldt-Stiftung","The third author wishes to acknowledge the Alexander von Humboldt-Foundation for funding his position at the WiB – TU Darmstadt under the research grant ITA-1185040-HFST-P (2CENENRGY project).

Compared to traditional continuous jointed bridges, integral abutment and jointless bridges (IAJBs) have better lateral stability because there are no expansion devices. The mechanical performance of Shangban IAJ bridge, located in Fujian, China, is thoroughly investigated by Finite Element Analysis (FEA). The numerical model is created and validated based on experimental results obtained from static load tests performed on the bridge. A detailed parametric analysis is carried out to assess the correlation between the flood-resistant performance and a number of parameters: skew angle, water-blocking area, span number, pile section geometry, and abutment height. Except for the abutment height, other parameters significantly affect the bridge performance. Furthermore, the change in the span number has a meaningful impact only when fewer than four spans are modeled. Finally, pushover analyses estimate the maximum transverse displacement and the sequence of plastic hinge creation as well as the mechanical behaviour of the structure under lateral flood loads. The analysis results show that IAJBs have better flooding-resistant performance than conventional jointed bridges. © 2020 Yizhou Zhuang et al.",,,,,,,,,,,,,,,,,,"Ghorbani, B., A field study of scour at bridge piers in flood plain rivers (2008) Turkish Journal of Engineering and Environmental Sciences, 32 (4), pp. 189-199;

Unfortunately, the real behavior of bridges in the nonlinear range is difficult to evaluate and a sound basis for the nonlinear FE analysis is not available. In addition, a nonlinear FE analysis is not feasible for practitioners to use. To tackle this problem, a new simplified approach based on linear FE analysis and field load testing is introduced in this paper to address the particular structural feature and topology of adjacent precast concrete box-beam bridges for the assessment of structural redundancy. The approach was first experimentally analyzed on a model bridge and then validated by a case study. The approach agrees well with the existing recognized method while reducing the computation complexity and improving the reliability. The analysis reveals that the level of redundancy of the bridge in the case study does not meet the recommended standard, indicating that the system factor recommended by the current bridge evaluation code for this bridge is inappropriate if considering the field condition. Further research on the redundancy level of this type of bridges is consequently recommended. © 2020 Yanling Leng et al.",,"Load testing; Nonlinear analysis; Precast concrete; Redundancy; Structural analysis; Bridge evaluation; Computation complexity; Concrete box beams; Non-linear finite-element analysis; Nonlinear fe analysis; Nonlinear ranges; Structural feature; Structural redundancy; Concrete beams and girders",,,,,,,,,,,,,,,,"Hulsbos, C.L., (1962) Lateral Distribution of Load in Multibeam Bridges, , Washington, DC, USA Transportation Research Board Highway Research Board Bulletin 339; Russell, H.G., (2009) Adjacent Precast Concrete Box Beam Bridges: Connection Details, , Washington, DC, USA Transportation Research Board NCHRP Report Synthesis 393; Leng, Y., Zhang, J., Jiang, R., He, H., (2013) Experimental Research on Transverse Load Distribution of Prefabricated Hollow Slab Concrete Bridges with Shear Key Cracks, 99. , Zürich, Switzerland International Association for Bridge and Structural Engineering IABSE Symposium Report; Leng, Y., Zhang, J., Jiang, R., He, H., Zhou, J., Experimental Research on Strengthening Transverse Connections of Prefabricated Concrete Hollow Core Slab Beam Bridges, , Proceedings of Transportation Research Board 94th Annual Meeting January 2015 Washington DC; Leng, Y., (2017) System Safety and Reliability Assessment for Adjacent Precast Concrete Box Beam Bridges, , Las Cruces, NM, USA New Mexico State University Doctorate dissertation; Aashto, (2017) Aashto Lrfd Bridge Design Specifications, , 7th Washington, DC, USA AASHTO; Aashto, (2018) Aashto Manual for Bridge Evaluation, , 3rd Washington, DC, USA AASHTO; Ghosn, M., Moses, F., (1998) Redundancy in Highway Bridge Superstructures, , Washington, DC, USA Transportation Research Board NCHRP Report 406; Ghosn, M., Yang, J., (2014) Bridge System Safety and Redundancy, , Washington, DC, USA NCHRP Report 776; Pinjarkar, S.G., An Overview of Current Worldwide Practices for Nondestructive Load Testing for Bridge Rating and Evaluation, , Proceedings of the 5th Annual International Bridge Conference 1988 Pittsburgh, PA, USA; Gb/j50283-1999, (1999) Unified Standard for Reliability Design of Highway Engineering Structures, , Beijing, China China Plan Press in Chinese; Moses, F., Dhirendra, V., (1987) Load Capacity Evaluation of Existing Bridges, , Washington, DC, USA Transportation Research Board NCHRP Report 301; Pedro, M., Eduardo, N., Assessment of the Shear Strength between Concrete Layers, , Proceedings of the 8th Fib Ph.D. Symposium in KGS June 2010 Lyngby, Denmark; Gb50010-2010, (2010) Code for Design of Concrete Structures, , Beijing, China China Plan Press in Chinese; Hambly, E.C., (1991) Bridge Deck Behaviour, , New York, NY, USA CRC Press","Jiang, R.; New Mexico State UniversityUnited States; email: rjiang@nmsu.edu",,,"Hindawi Limited",,,,,16878434,,,,"English","Adv.

Two modern antifriction polymers were considered as sliding layer materials: modified PTFE and antifriction composite material based on PTFE with spherical bronze inclusions and molybdenum disulfide. The physicomechanical and frictional properties of the antifriction spherical layer materials were obtained experimentally by the scientific team of Alfa-Tech LLC and Institute of Continuous Media Mechanics of the Ural Branch of Russian Academy of Science. The approximation of the experiments results the dependence of friction coefficient on the pressure was performed and functions approximating the experiments results with a maximum error of 2.3% were obtained. The approximating functions were used to determine the friction coefficient at pressures > 54 MPa acting on the spherical bearing. A series of numerical experiments aimed at identifying the qualitative and quantitative patterns of the deformation behavior of the spherical thin sliding layer materials was carried out as part of the work: contact pressure, contact tangential stress, contact status. Comparison of settlement of numerical models of spherical bearing with a modified PTFE layer and experiments data was performed in the work. It is established that the model taking into account grooves with a lubricant has a minimum settlement error under the frictional properties of the interlayer material declared by the manufacturer, which is approximately 8.44%. The settlement error for all considered bearing models is more than 15% with considering frictional properties of antifriction materials obtained experimentally. © 2020, Springer Nature Switzerland AG.","Composite antifriction material; Contact; Elements of transport and logistics systems; FEM; Friction; Lubrication; Modified PTFE; Polymer properties; Spherical bearing","Bearings (machine parts); Contacts (fluid mechanics); Deformation; Errors; Finite element method; Layered semiconductors; Lubrication; Molybdenum compounds; Polytetrafluoroethylenes; Spheres; Sulfur compounds; Antifriction materials; Friction coefficients; Frictional properties; Logistics system; Numerical experiments; Polymer properties; Russian Academy of Sciences; Spherical bearings; Friction",,,,,"Russian Science Foundation, RSF: 18-79-00147","The study supported by a grant of Russian Science Foundation (project No. 18-79-00147).",,,,,,,,,,"Xue, J.Q., Briseghella, B., Chen, B.C., Zhang, P.Q., Zordan, T., Optimal design of pile foundation in fully integral (2016) Dev.

The numerical model was implemented in the well-known FEM software CSIBridge. The isolated bridge has been analyzed using nonlinear time history analysis method with seven pairs of earthquake records and the results are compared for the two isolation systems.

The road roughness is assumed by a stationary random process. The bridge has three spans which is modeled by FEM. The moving vehicle has three axles and is idealized by 6-DOFs. Monte-Carlo method is used to create the random road roughness input. The governing equation of dynamic vehicle-bridge interaction is established by means of d’Alembert’s principle. Galerkin method and Green theory are applied to discrete the governing equation in the space domain. In this paper, Runge-Kutta methodology was used to solve the governing equation in the time domain. After analyzing with a series profile of road roughness input, it is going to obtain the response of bridge output which is also the random process. The FEM analysis totally agrees with the test results of KhueDong Bridge. Furthermore, the road roughness also was investigated to clarify the effects on dynamic impact factor. Finally, when road roughness condition changes from the type A to type E, dynamic impact factor has risen considerably. © 2020, Springer Nature Singapore Pte Ltd.","Dynamic impact factor (DIF); Monte-Carlo method; Road roughness; Runge-Kutta methodology; Super T Girder Bridge; Truck","Galerkin methods; Monte Carlo methods; Random processes; Road vehicles; Roads and streets; Runge Kutta methods; Time domain analysis; Trucks; Dynamic impact factor; FEM analysis; Governing equations; Moving vehicles; Road roughness; Stationary random process; T-girders; Vehicle-bridge interaction; Highway bridges",,,,,,,,,,,,,,,,"(2012) LRFD Bridge Design Specifications, , AASHTO, Washington, DC, USA; Coussy, O., Said, M., van Hoore, J.P., The influence of random surface irregularities on the dynamic response of bridges under suspended moving loads (1989) Journal of Sound and Vibration, 130 (2), pp. 13-320; Lombaert, G., Conte, J.P., Random vibration analysis of Dynamic Vehicle-Bridge interaction due to Road Roughness (2012) Journal of Engineering Mechanics, 816, p. 825; Nguyen, X.-T., Tran, V.-D., Hoang, N.-D., A Study on the Dynamic Interaction between Three-Axle Vehicle and Continuous Girder Bridge with Consideration of Braking Effects (2017) Journal of Construction Engineering, 2017; Sun, L., Simulation of pavement roughness and IRI based on power spectral density (2003) Mathematics and Computers in Simulation, 61, pp. 77-88; Mechanical Vibration – Road Surface Profiles – Reporting of Measured Data; Ray, W.C., Joseph, P., (1995) Dynamics of Structures, , 3rd Ed.

In these methods, the non-destructive test has a widespread application thanks to its feasibility and effectiveness. The vibration-based approach determines the cable tension based on natural frequency. In fact, there are many factors that can influence the tension values. Some of them are derived from objective factors, others from subjective factors. In this paper, a subjective issue, so-called measurement technique, is studied. A cable, without fillings between the HDPE duct and strands, is the main object of this study. In the first step, some scenarios related to the placement of sensors are conducted. The former considers the tension between different positions of sensors, directly and indirectly contact conditions with strands, under the ambient and pulling-rope excitation. The latter takes into account the directions, out-of-plane and in-plane, of sensor placement on the strands or HPDE duct. In the next step, the relationship between the force and frequency is utilized to identify the mean tension of the cable. In the finally step, results of cable tension estimation are compared with the real-time monitoring and finite element (FE) simulation. From the comparison, the effects of measuring technique in situ are discussed in the conclusion. © Springer Nature Singapore Pte Ltd 2020.","Cable tension; Dynamic measurement; Finite element analysis; Kien bridge; Non-destructive test; Vibration",,,,,,"VN2018TEA479A103; Vlaamse regering","Acknowledgements.

This method borrows ideas from fictitious domain methods, where the geometry is immersed into a non-body-fitted background mesh, but is able to produce a computational mesh that can be used for both classical FEM and fictitious domain methods, as shown in the numerical results. The key point is to transfer the B-rep geometry into an implicit representation using level-set functions and use this implicit description to reconstruct Lagrangian elements that accurately match the given domain boundary. copyright © Crown copyright (2018).All right reserved.","CAGD; Embedded domain methods; Fictitious domain methods; Higher-order FEM; NURBS","Bridges; Computational fluid dynamics; Computational mechanics; Finite element method; Mesh generation; CAGD; Embedded domain methods; Fictitious domain method; Higher order FEM; NURBS; Numerical methods",,,,,,,,,,,,,,,,"Marussig, B., Hughes, T.J.R., A review of trimming in isogeometric analysis: Challenges, data exchange and simulation aspects (2017) Archive Comp.

Findings: The results from parametric analyses offer a clear perspective about the buckling capacity but also about the post-buckling behavior and strength of the models. Research limitations/implications: This makes possible to compare the response of the different fiber-reinforced polymers used in the computational model. Originality/value: Furthermore, this investigation leads to useful conclusions for the material design optimization of the load-carrying box girder, as significant advantages derive not only from the combination of different fiber-reinforced polymers in hybrid material structures, but also from Kevlar-fiber blades. © 2019, Emerald Publishing Limited.","Composite materials; Finite element analysis","Beams and girders; Box girder bridges; Buckling; Composite materials; Fiber reinforced plastics; Finite element method; Hybrid materials; Polymers; Reinforcement; Turbine components; Turbomachine blades; Wind turbines; Computational model; Design/methodology/approach; Fiber reinforced polymers; Material structure; Nonlinear buckling analysis; Parametric -analysis; Postbuckling behavior; Wind turbine blades; Structural design",,,,,,,,,,,,,,,,"(2007) User’s Manual, , Swanson Analysis System, Houston, TX; Ashwill, T.D., Materials and innovations for large blade structures: research opportunities in wind energy technology (2009) 50th AIAA Structures, Structural Dynamics & Materials Conference Palm Springs, , CA: May 4-6; Burton, T., Sharpe, D., Jenkins, N., Bossanyi, E., (1991) Wind Energy Handbook, , Wiley, NJ; Chen, X., Zhao, W., Zhao, X.L., Xu, J.Z., Failure test and finite element simulation of a large wind turbine composite blade under static loading (2014) Energies, 7 (4), pp. 2274-2297; Cox, K., Echtermeyer, A., Structural design and analysis of a 10MW wind turbine blade (2012) Energy Procedia, 24 (2), pp. 194-201; Gaudern, N., Symons, D., Comparison of theoretical and numerical buckling loads for wind turbine blade panels (2010) Wing Engineering, 34 (2), pp. 193-206; Griffin, D.A., (2001) WindPact Turbine Design Scaling Studies Technical Area 1 – Composite Blades for 80- to 120-Meter Rotor, , NREL, Washington, DC; Grujicic, M., Arakere, G., Subramanian, E., Sellappan, V., Vallejo, A., Ozen, M., Structural-response analysis, fatigue–life prediction, and material selection for 1MW horizontal-axis wind turbine blades (2009) Journal of Materials Engineering and Performance, 19, pp. 790-801; Haselbach, P.U., Bitsche, R.D., Branner, K., The effect of delaminations on local buckling in wind turbine blades (2016) Renewable Energy, 85 (3), pp. 295-305; Jensen, F.M., Falzon, B.G., Ankersen, J., Stang, H., Structural testing and numerical simulation of a 34m composite wind turbine blade (2006) Composite Structures, 76, pp. 52-61; Mutkule, S.K., Gorad, P.P., Raut, S.R., Nikam, A.H., Optimum and reliable material for wind turbine blade (2015) International Journal of Engineering Research & Technology, 4 (2), pp. 624-627; Praveen Shaju, C., Manikandan, T., Sai Balaji, S., Experimental study on environmental exposure of Kevlar Epoxy composites (2013) International Journal of Emerging Technology and Advanced Engineering, 3 (10), pp. 116-124; (2015) Renewables 2015 global status report, , Renewable Energy Policy Network for the 21st Century, Paris; Sorensen, B.F., Jorgensen, E., Debel, C.P., Jensen, F.M., Jensen, H.M., Jacobsen, T.K., Halling, K.M., (2004) Improved design of large wind turbine blade of fiber composites based on studies of scale effects (phase 1) – summary report, , Risø-R-1390(EN), Risø National Laboratory, Roskilde; Theotokoglou, E.E., Balokas, G.A., A micro-scale structural response comparison between GFRP and CFRP wind turbine blades (2015) Proceedings of the 8th GRACM International Congress on Computational Mechanics, , Volos: July 12–15; Theotokoglou, E.E., Balokas, G.A., Computational analysis and material selection in cross-section of a composite wind turbine blade (2015) Journal of Reinforced Plastics and Composites, 34 (2), pp. 101-115; Thomsen, O.T., Sandwich materials for wind turbine blades – present and future (2009) Journal of Sandwich Structures and Materials, 11 (1), pp. 7-27; Zimmer, J.E., Cost, J.R., Determination of the elastic constants of a unidirectional fiber composite using ultrasonic velocity measurements (1970) Journal of the Acoustical Society of America, 47 (6), pp. 795-803","Theotokoglou, E.E.; School of Applied Mathematical and Physical Sciences, Greece; email: stathis@central.ntua.gr",,,"Emerald Group Holdings Ltd.",,,,,17579864,,,,"English","Int.

The relationship between the stress concentration and the compliance of corner-filleted flexure hinges is first analyzed. Considering the stress concentration, coupled with a wide range of geometrical parameters, empirical compliance equations for conventional flexure hinges, are then obtained by using the exponential model. Subsequently, the proposed equations are unified. To verify the validity and accuracy of these equations, the characteristics of a bridge-type flexure-based mechanism are then analyzed by the proposed equations and finite element analysis, respectively. The results of compliances and displacement amplification ratios obtained by these two methods are in good agreement. It demonstrates that the empirical compliance equations could be obtained by exponential model, and these equations can be unified. © 2019, Springer Nature Switzerland AG.","Compliance; Compliant mechanism; Empirical compliance equations; Exponential model; Flexure hinge","Geometry; Stress concentration; Bridge-type; Displacement amplification; Exponential models; Flexure hinge; Flexure-based mechanism; Single-axis; Hinges",,,,,"Natural Science Foundation of Beijing Municipality: 3194044; Postdoctoral Research Foundation of China: 2017-ZZ-034","This work was supported by Beijing Natural Science Foundation (3194044), and Beijing Postdoctoral Research Foundation of China (2017-ZZ-034).",,,,,,,,,,"Lobontiu, N., (2010) Compliant mechanisms:design of flexure hinges, pp. 2-15. , CRC Press, Boca Raton; Wan, S., Zhang, Y., Xu, Q., Design and development of a new large-stroke XY compliant micropositioning stage (2017) Proc IMechE Part C J Mech Eng Sci, 231, pp. 3263-3276; Liu, M., Zhang, X., Fatikow, S., Design and analysis of a multi-notched flexure hinge for compliant mechanisms (2017) Precis Eng, 48, pp. 292-304; Clark, L., Shirinzadeh, B., Pinskier, J., Topology optimization of bridge input structures with maximal amplification for design of flexure mechanisms (2018) Mech Mach Theory, 122, pp. 113-131; Hopkins, J.B., Vericella, J.J., Harvey, C.D., Modeling and generating parallel flexure elements (2014) Precis Eng, 38, pp. 525-537; Li, T.M., Zhang, J.L., Jiang, Y., Derivation of empirical compliance equations for circular flexure hinge considering the effect of stress concentration (2015) Int J Precis Eng Manuf, 16, pp. 1735-1743; Elgammal, A.T., Fanni, M., Mohamed, A.M., Design and analysis of a novel 3d decoupled manipulator based on compliant pantograph for micromanipulation (2017) J Intell Robot Syst, 87, pp. 43-57; Pinskier, J., Shirinzadeh, B., Clark, L., Design, development and analysis of a haptic-enabled modular flexure-based manipulator (2016) Mechatronics, 40, pp. 156-166; Verma, S., Kim, W.J., Shakir, H., Multi-axis maglev nanopositioner for precision manufacturing and manipulation applications (2015) IEEE Trans Ind Appl, 41, pp. 1159-1167; Hao, G.B., Li, H., Kavanagh, R., Design of decoupled, compact, and monolithic spatial translational compliant parallel manipulators based on the position space (2016) Proc IMechE Part C J Mech Eng Sci, 230, pp. 367-378; Choi, K.B., Lee, J.J., Kim, G.H., Amplification ratio analysis of a bridge-type mechanical amplification mechanism based on a fully compliant model (2018) Mech Mach Theory, 121, pp. 355-372; Clark, L., Shirinzadeh, B., Zhong, Y., Design and analysis of a compact flexure-based precision pure rotation stage without actuator redundancy (2016) Mech Mach Theory, 105, pp. 129-144; Huang, H., Fu, L., Zhao, H., Note: a novel rotary actuator driven by only one piezoelectric actuator (2013) Rev Sci Instrum, 84, p. 096105; Yong, Y.K., Lu, T.F., Comparison of circular flexure hinge design equations and the derivation of empirical stiffness formulations (2009) IEEE/ASME International Conference on Advanced Intelligent Mechatronics, IEEE, pp. 510-515. , Singapore, 14–17 July 2009; Schotborgh, W.O., Kokkeler, F.G.M., Tragter, H., Dimensionless design graphs for flexure elements and a comparison between three flexure elements (2005) Precis Eng, 29, pp. 41-47; Acer, M., Sabanovic, A., Comparison of circular flexure hinge compliance modeling methods (2011) IEEE International Conference on Mechatronics, IEEE, pp. 271-276. , Istanbul, Turkey, 13–15 Apr 2011; Paros, J.M., How to design flexure hinges (1965) Mach Des, 37, pp. 151-156; Smith, S.T., Badami, V.G., Dale, J.S., Elliptical flexure hinges (1997) Rev Sci Instrum, 68, pp. 1474-1483; Tian, Y., Shirinzadeh, B., Zhang, D., Three flexure hinges for compliant mechanism designs based on dimensionless graph analysis (2010) Precis Eng, 34, pp. 92-100; Lobontiu, N., Garcia, E., Hardau, M., Stiffness characterization of corner-filleted flexure hinges (2004) Rev Sci Instrum, 75, pp. 4896-4905; Meng, Q., Li, Y., Xu, J., New empirical stiffness equations for corner-filleted flexure hinges (2013) Mech Sci, 4, pp. 345-356; Yong, Y.K., Lu, T.F., Handley, D.C., Review of circular flexure hinge design equations and derivation of empirical formulations (2008) Precis Eng, 32, pp. 63-70; Li, T.M., Du, Y.S., Jiang, Y., Empirical compliance equations for constant rectangular cross section flexure hinges and their applications (2016) Mathematical Problems in Engineering","Du, Y.; College of Mechanical Engineering and Applied Electronics Technology, China; email: duyunsongwei@163.com",,,"Springer Nature",,,,,25233971,,,,"English","SN Appl.

To clarify the mechanism of the assembly process, we apply PNIPAM to thin rectangular bilayers with another hydrophobic polymer polycaprolactone (PCL), which can turn into self-bending curved bridges in 25 °C aqueous environment. This simple bilayer geometry makes it possible from 2D to 3D automatically and can be applied to thermally responsive actuation of micro-devices. Then we proposed a self-folding table-like structure which is thermally responsive. Moreover, the finite element analysis (FEA) and experiments are employed to validate the assembly process.

FEA course is normally offered as one of the engineering subjects. Nowadays, many softwares are available with so many features and variations of analysis when it comes to FEA. And, it has always been a challenge for educators, in finding suitable examples and tutorials to deliver the course concept. Hence, the planned project in this course is expected to familiarize the students with the various important tools and fundamental concept in understanding the subject. Truss analysis is purposely chosen to accomplish this task. Not only the structural engineering analysis concept is applied, but it will also be used in Truss Bridge Model Competition. This project is also one of the examples to show the linkage between academic knowledge and industrial needs. Thus, it is also hoped that, the skills gathered from this subject can enhance the marketability of the students upon graduation. © 2019 IEEE.","Finite Element Analysis (FEA); Project; Structural Engineering","Bridges; Education computing; Engineering education; Structural analysis; Structural design; Students; Trusses; Fundamental concepts; Project; Truss analysis; Truss bridge; Finite element method",,,,,"Universiti Teknologi MARA, UiTM","ACKNOWLEDGMENT The authors would like to acknowledge the financial support from Institute for Infrastructure Engineering and Sustainable Management (IIESM) and Faculty of Civil Engineering (FCE) of Universiti Teknologi MARA (UiTM), Shah Alam, Selangor, Malaysia.

In addition to the block shear failure mode to which most gusset plates in bridge trusses and those in braced building frames are subject, a narrow tapered gusset plate may also fail in the inclined net section fracture mode. The inclined net section fracture mode has been observed in failed gusset plates, but to the authors' knowledge no explicit formula has been proposed in the literature for use in engineering practice. This paper first demonstrates that, for a rectangular bolted gusset plate failing in net section fracture, the ultimate capacity can be determined accurately using the net section across the whole width, without any reference to the Whitmore concept. It then shows through finite-element analysis that the outer net section fractures of a tapered plate are inclined rather than normal to the loading direction. A practical design equation is proposed to determine the net section tension capacity of a tapered gusset plate, and is shown to reasonably match the ultimate loads of specimens tested by independent workers. The existing resistance factor can be applied conservatively to the design equation. This paper includes examples illustrating the governing failure modes of rectangular and tapered bolted gusset plates in tension. © 2019 American Society of Civil Engineers.","Block shear; Bolted connection; Connection design; Tapered gusset plate; Tension capacity; Whitmore section","Fracture; Joints (structural components); Block shear; Bolted connections; Connection designs; Gusset plates; Tension capacity; Whitmore section; Bolts",,,,,"University of Wollongong, UOW","This research was conducted with the support of the Australian Government Research Training Program Scholarship for the first author, administered by the University of Wollongong.

In the proposed method, only some of the concrete members of the bridge are cast in place and then joined with precast concrete copings with internal connectors or precast concrete girders. This method enhances constructability by facilitating field assembly and minimizing the field casting work. Furthermore, in the case of a bridge exposed to ocean loads, the structural stability can be improved by integrating steel piers with the precast concrete copings. To analyze the connection behavior of a bridge constructed via the proposed method, a full-scale specimen with a span of 3.0 m was fabricated and tested under lateral loading. A finite element analysis model was also developed for theoretical analysis. The experimentally and theoretically determined lateral behaviors of the bridge during each loading step were compared. The final failure mode of the bridge yielded to the reinforcement in the joint between a precast coping and a cast-in-place member. Nevertheless, the proposed method was found to offer improved structural performance, increasing the maximum lateral load of the bridge to 210% of the design value. © 2019","Coping; Finite element analysis; Internal connector; Lateral load; Marine structure; Precast; Structural behavior","Bridges; Cast in place concrete; Concrete beams and girders; Finite element method; Ocean structures; Offshore structures; Piers; Stability; Structural analysis; Bridge constructions; Coping; Finite element analysis model; Lateral loads; Pre-cast; Structural behaviors; Structural performance; Structural stabilities; Precast concrete; bridge construction; concrete structure; finite element method; loading; reinforcement; steel structure; structural component",,,,,"Kyung Hee University: KHU-20190979","This work was supported by a grant from Kyung Hee University , Republic of Korea in 2019 ( KHU-20190979 ).",,,,,,,,,,"(2017), Korea Culture and Tourism Institute.

For this purpose, experimental and numerical studies were carried out on the five post-tensioned balanced cantilever bridges constructed in the city of Artvin, Turkey. First, the experimental and theoretical dynamic characteristics of the selected five bridges were determined using the ambient vibration-based Operational Modal Analysis and Finite Element Method, respectively. Then, the bridge model, which is given the highest correlation between the experimental and theoretical frequencies, was selected to determine the most important parameters that affected the modal behavior of the bridges. The most important parameters were determined as bridge length and pier height. Theoretical modal analyses were carried out for a series of bridge models with different lengths and heights. Finally, a simplified fundamental frequency formula was developed for the post-tensioned balanced cantilever bridges using the method of least squares considering the frequency values obtained from the theoretical modal analyses of the bridge models. The developed formula was checked with the experimentally obtained values, and it was observed that both sets of results were close to each other. © 2019, Springer Nature Switzerland AG.","Ambient vibration tests; Finite element method; Operational modal analysis method; Post-tensioned balanced cantilever bridges; Simplified natural fundamental frequency formula",,,,,,,"The authors would like to express their gratitude to the General Directorate of State Hydraulic Works, DOLSAR Engineering Co.

Based on actual engineering project, the plate-beam finite element method is used to study the shear lag effect of the three-span continuous-curve steel box-girder bridge under the variety conditions of the curve radius, and the width span ratio, and the distribution of the shear lag effect in the longitudinal and horizontal direction under the symmetrical load are summarized in this paper, providing references for design of steel box-girder bridge. The results show that the shear lags of steel box girders are all positive shear lags under symmetrical loads. Under the conditions of three parameters, the curve radius and the width-span ratio have a great influence on the shear lag effect of steel box girders, and the high-span ratio change has no obvious effect on the shear lag effect, and the shear lag effect of bottom plate is far less severe than the top plate. © 2019 Published under licence by IOP Publishing Ltd.","curvature radius; shear lag effect; steel box girder","Bridge decks; Composite beams and girders; Curved beams and girders; Fiber optic sensors; Shear flow; Steel bridges; Steel structures; Beam finite elements; Box section beam; Curvature radii; Curve steel box girders; Engineering project; Shear lag effects; Steel box girders; Three parameters; Box girder bridges",,,,,"National Natural Science Foundation of China, NSFC: 11502172; Guangdong Science and Technology Department, GDSTC: 2016A040403125","The paper supported by the Special Funds of the National Natural Science Foundation of China (11502172) and Guangdong Science and Technology Department Project (2016A040403125).",,,,,,,,,,"Zhang, Y., Su, Y., Lin, L., Finite Beam Element Analysis on Shear Lag Effect of Skewly Supported Continuous Box Girder (2010) Journal of the China Railway Society, pp. 44-50; Li, Y., Zhang, Y., Fan, J., Shear lag effect study of cracked steel-concrete continuous beams (2010) Journal of Building Srtuctures, pp. 390-397; Li, X., Wan, S., Chen, J., Mo, Y., Analysis on shear lag effect in thin-walled box girders based on modified warping displacement function (2018) Journal of Southeast University, pp. 851-856; Chen, S.S., Aref Amjad, J., Methee, C., Il-Sang, A., Proposed Effective Width Criteria for Composite Bridge Girders (2007) Journal of Bridge Engineering, pp. 325-338; Aref Amjad, J., Methee, C., Chen Stuart, S., Ahn Il-Sang.

One is running at a uniform speed in a straight line, the other is running at an assumed speed with a minimum turning radius.

Ltd, Guangzhou, China","The high-voltage dis-connector, as a key substation equipment in the power grid structure, is vitally important to the quality of the power grid operation. Due to the geographic location of Guangdong Province of China, many strong typhoons have caused great damage to power facilities in recent years. And the loss of the dis-connector is the most serious, which severely affects the reliability of the power supply. However, the research on the wind resistance of the dis-connector is still few, so the improvement work of the device is quite difficult. The phenomenon of strong typhoon destroying the dis-connector mainly includes the fracture of post insulator and the conductive arm. In the study of the mechanical properties of post insulator and the conductive arm, almost all wind loads are treated as a concentrated force, but the surfaces of the post insulator and the conductive arm are actually subjected to a continuous wind pressure distribution. The magnitude of the wind load and the error of its application method will inevitably lead to inaccurate stress and strain data obtained in the calculation of the strength of the post insulator and the conductive arm, so that the post insulator and the conductive arm cannot be accurately designed. In this paper, the wind resistance of the dis-connector are studied by using the fluid-structural coupling analysis method. Firstly, the hydrodynamic RNG k-ϵ turbulence model is used to simulate the wind field around the dis-connector, so as to obtain the accurate result of the wind pressure distribution on the surface of the dis-connector. Then the surface pressure of the dis-connector calculated by hydrodynamics simulation is introduced into the structural module of Ansys software as the applied load. The finite element method is used to simulate and calculate the stress and strain of the dis-connector, so as to obtain the mechanical characteristics of the dis-connector under strong wind. In addition, this paper analyzes the effects of different wind speeds and different wind directions on the wind load applied to the surface of dis-connector, and provide a basis for wind resistance design of dis-connector. © 2019 IEEE.","dis-connector; fluid-structural coupling.; wind resistance","Aerodynamic loads; Bridge cables; Computer software; Hurricanes; Hydrodynamics; Mechanical properties; Pressure distribution; Structural dynamics; Turbulence models; Wind stress; Geographic location; Hydrodynamics simulations; Mechanical characteristics; Power grid operations; Structural coupling; Substation equipment; Wind pressure distribution; Wind resistance; Electric power transmission networks",,,,,"China Southern Power Grid, CSPG: GDKJXM20180153"," This work is supported by Technical Project of China Southern Power Grid Project (Project Number: GDKJXM20180153)",,,,,,,,,,"Suhua, P., (2013) Numerical Simulation and Failure Mechanism Analysis of Stress Distribution of Rod-shaped Porcelain Insulators [ D], , Hunan University; Wang, S., Qi, J., Niu, J., Stress analysis of 160kn rod-shaped suspension porcelain insulators (2002) Electric Porcelain Arrestors, 3, pp. 3-7; Sun, T., Xiao, H.-N., Finite element simulation analysis of bending stress of rod-shaped porcelain insulator (2007) Electric Porcelain Arrestors, 2, pp. 19-21; Cai, Y., Jing, H., Fan, L., Stress analysis of 110 kv rod-shaped suspension porcelain insulators (2005) Insulation Materials, 38 (4), pp. 32-35; Liu, X., Feng, T., Calculation of wind loads of post insulators in isolation switches (2015) High Voltage Apparatus, 5, pp. 83-88; Gui, C., Baojiang, C., Gui, C., Research on the wind-resistant structure of composite insulators for overhead contact system cantilever used based on fluid-structure interaction method (2016) IEEE International Conference on High Voltage Engineering & Application.

For the cable-stayed bridge, the cable receives the load from the bridge deck and transfer it to the pylon. As the ambient temperature change, the internal force in bridge element including stayed cable will change. This research investigate the ambient temperature effect to the tension force of stayed cable of cable-stayed bridge by comparing the result of finite element model analysis with the field measurement form electromagnetic sensor data. The finite element model of Merah Putih Cable-Stayed Bridge has been developed based on detailed engineering design data. The finite element model is validated using the natural frequency data from dynamic load test of the bridge. The ambient temperature and bridge elements temperature were measured for 24 hours. The finite element analysis were conducted based on field measurement data and the contribution of pylon and girder temperature to the cable tension forces variation was investigated. The output of finite element analysis then compared to the actual cable tension as measured by an electromagnetic sensor. It was found that the ambient temperature will affecting the magnitude of tension force at stay cable and the variation of cable tension has similar pattern of both from the finite element model and electromagnetic data. As the temperature of bridge element increases or decreases, the bridge will experience a deformation. Since the stay cable connected to the pylon at one side and to the girder at the other side, its will make the stay cable elongated or contracted which in turn will affecting the tension force at stay cable. When evaluating the bridge condition based on the tension force at stay cable, the effect of temperature variation need to be considered. © BEIESP.","Cable; Cable tension; Cable-stayed bridge; Electromagnetic sensor; Finite element method; Temperature",,,,,,"Binus University: 12/AKM/PNT/2019","This work is supported by the Directorate General of Strengthening for Research and Development, Ministry of Research, Technology, and Higher Education, Republic of Indonesia as a part of Penelitian Terapan Unggulan Perguruan Tinggi Research Grant to Binus University entitled “Pengaruh Suhu Terhadap Perubahan Gaya di Kabel Jembatan” or “Temperature Effect to Cable Force Variation of Bridge” with contract number: 12/AKM/PNT/2019 and contract date: 27 March 2019.",,,,,,,,,,"Chen, C., Wu, W., Liu, C., Effects of temperature variation on cable forces of an extradosed bridge (2012) 6Th European Workshop on Structural Health Monitoring; Vairo, G., Montassar, S., Mechanical modelling of stays under thermal loads (2012) Mechanics, Models and Methods, LNACM, 61, pp. 481-498; Suangga, M., Hidayat, I., Yuliastuti, C., Temperature effect on cable tension forces of cable-stayed bridge (2018) The 2Nd International Conference on Eco Engineering Development, , 2018; Wang, L., Wu, Y., Thermal effect on damaged stay-cable (2014) Journal of Theoretical and Applied Mechanics, 52 (4), pp. 1071-1082; Zhao, Y., Zhao, Y., Sun, C., Wang, Z., Temperature effect on tension forces and frequencies of suspended cables (2014) Proceedings of the 9Th International Conference on Structural Dynamics; Zhou, Y., Sun, L., Sun, S., Temperature field and its effect on a long-span steel cable-stayed bridge based on monitoring data (2013) The Thirteenth East Asia-Pacific Conference on Structural Engineering and Construction, pp. EASEC-13",,,,"Blue Eyes Intelligence Engineering and Sciences Publication",,,,,22498958,,,,"English","Int.

Base pipe pins are composed of two steel pipes: one pipe is embedded in the column and the other in the adjoining member. Shear force is transferred through contact of the pipes and friction. The uplift force is resisted by a tension member and welded studs on the surface of the column pipe. To investigate the behavior and failure mode of base pipe pins under direct tension and to determine the ultimate tensile capacity of the pins, two scaled pipe pin connections were tested under direct tension. Elaborate nonlinear finite element (FE) studies of the pipe pins were also conducted to explore the effects of different parameters on the response of the pins. There are many possible failure modes that could occur under tension. Test results depicted that rupture of the pin tension member with no damage to the connection was the dominant failure mode in pure tension. The FE models accurately estimated the response of the test models and the observed failure mode. The analytical results showed that decreasing the pipe height alters the failure mode but does not affect the ultimate capacity of the connection significantly. Furthermore, reducing the pipe height or increasing the number of stud layers has a small effect on the ultimate capacity and stiffness of the connections. © 2019 Elsevier Ltd","ABAQUS; Direct pull test; FE model; Pipe pin; Stud; Tension; Threaded rod","ABAQUS; Studs (fasteners); Studs (structural members); Tensile strength; Direct pull; FE model; Stud; Tension; Threaded rods; Failure modes; analytical framework; experimental study; failure mechanism; finite element method; numerical model; pipe; pullout test; stiffness; tensile strength; tension",,,,,"California Department of Transportation, CT: 65A0423","The study presented in this paper was funded by Caltrans under grant No. 65A0423 .

Multi-steel girder bridges experience differential deflection between adjacent girders when subject to vertical loads resulting in a driving force in cross-frame diaphragms. The driving force developed in the cross-frame legs leads to out-of-plane distortion of the web-gap which results in high stress concentrations at the area, following by fatigue damages. This paper introduces an innovative method to retrofit web-gap distortion cracking, upgrade existing retrofits, and compare its effectiveness with two common retrofit techniques. The method involves cutting the existing connection plate and using angles to attach the disconnected part of the connection plate to the web. The method intends to eliminate the local high stresses at the connection plate end with considering minimal interference in original connection design and load path. Also, two other conventional repair methods were investigated, slot method and top-angle measure, to use as a basis for comparing the methods effectiveness. Laboratory testing was performed on a small-scale steel bridge bay by applying a vertical displacement to the free end of a cross-frame diaphragm to simulate the differential deflection between two adjacent girders in real bridges. The results from the testing were compared to findings from finite element analyses (FEA). Test results as well as FEA results for all investigated retrofit techniques are presented herein. Results showed that the newly developed slot-angle technique has significant potential for effectively reducing the stress concentrations in the web-gap region by removing the location of initial stress concentrations and redistributing those stresses over a wider area. © 2019, The Author(s).","Distortion-induced; Repair; Secondary cracking; Steel bridge",,,,,,,,,,,,,,,,,"Alavi, A.H., Hasni, H., Jiao, P., Borchani, W., Lajnef, N., Fatigue cracking detection in steel bridge girders through a self-powered sensing concept (2017) J Constr Steel Res, 128, pp. 19-38; Alemdar, F., Nagati, D., Matamoros, A., Bennett, C., Rolfe, S., Repairing distortion-induced fatigue cracks in steel bridge girders using angles-with-plate retrofit technique.

Free vibration tests of a lifting girder segment of a kilometer-span cable-stayed bridge were carried out in a wind tunnel to study its aerodynamic performance. Large aerostatic displacements were observed in the wind velocity range of concern. Large-amplitude limit cycle oscillations (LCOs) around the horizontal axis perpendicular to the bridge span occurred when the full-scale velocity exceeded 25.3 m/s. The analytical expression of the eigenfrequency of the dangerous mode of a lifting girder segment was derived, and the analytical result was compared with those determined by using the finite-element analysis (FEA) and testing results. The characteristics of the large-amplitude LCOs under different conditions were thoroughly analyzed. For various testing cases, the influences of the angle of attack, wind velocity, and vibration amplitude on the vibration frequency and aerodynamic damping ratio were comprehensively investigated and the parameter identification accuracies were verified. It was demonstrated that more attention should be paid to assessing the wind-resistance of lifting girder segments to ensure the construction safety of long-span bridges. The results of the present work can provide beneficial reference for evaluating the wind-resistance performances of similar types of lifting girder segments. © 2019 American Society of Civil Engineers.","Aerodynamic damping ratio; Bridge girder segment; Frequency; Large-amplitude limit cycle oscillation; Lifting construction; Wind tunnel test","Angle of attack; Bridge cables; Cable stayed bridges; Damping; Highway bridges; Plate girder bridges; Wind stress; Wind tunnels; Aerodynamic damping ratio; Bridge girder; Frequency; Limit Cycle Oscillation (LCO); Wind tunnel tests; Lift",,,,,"National Natural Science Foundation of China, NSFC: 51478087; National Basic Research Program of China (973 Program): 2015CB057705; Fundamental Research Funds for the Central Universities: DUT17ZD228","The research presented here was jointly supported by the Fundamental Research Funds for the Central Universities (DUT17ZD228), the National Program on Key Basic Research Project (973 Program, 2015CB057705), and the National Science Foundation of China (51478087), all of which support is gratefully acknowledged.",,,,,,,,,,"Abdel-Rohman, M., Spencer, B.F., Control of wind-induced nonlinear oscillations in suspended cables (2004) Nonlinear Dyn., 37 (4), pp. 341-355. , https://doi.org/10.1023/B:NODY.0000045545.87106.cc; Andrianne, T., Vincent, D.V.D.G., (2016) Mitigation of the Torsional Flutter Phenomenon of Bridge Deck Section during A Lifting Phase, , Proc. 8th International Colloquium on Bluff Body Aerodynamics and Applications.

To study the flexibility of stent, the following work was carried out by using the finite element method: Four mechanical models were adopted to simulate the bending deformation of stents, and comparative studies were conducted about the distinction between cantilever beam and simply supported beam, as well as the distinction between moment-loading method and displacement-loading method. A complete process as implanting a stent including compressing, expanding and bending was also simulated, for analyzing the effects of compressing and expanding deformation on stent flexibility. At the same time, the effects of the arrangement and the number of bridges on stent flexibility were researched. The results show that: 1. A same flexibility index was obtained from cantilever beam model and simply supported beam model; displacement-loading method is better than moment-loading for simulating the bending deformation of stents. 2. The flexibility of stent with compressing and expanding deformation is lower than that in the initial form. 3. Crossly arranging the neighboring bridges in axial direction, can effectively improve the stent flexibility and reduce the flexibility difference in various bending directions; the bridge number, has proportional non-linear correlation with the stent rigidity as well as the maximum moment required for bending the stent. © 2018 The Society of Theoretical and Applied Mechanics.","Bridges;

The objective of this research was to monitor the initial in-service behavior of the precast-prestressed concrete primary elements of Bridge A7957 and to obtain the load distribution of the bridge using field and finite element models (FEM) data. An initial series of diagnostic load tests was conducted on the bridge superstructure. Embedded sensors recorded strain variations at different section of the instrumented girders for different load configurations. An automated total station (ATS) collected the vertical deflection of the girders at several locations during the application of different test loads. The load distribution for moment was obtained experimentally (using deflection and strain data), FEMs, and using the AASHTO LRFD Bridge Design Specifications. The distribution factors for moment estimated with the AASHTO LRFD equations resulted in larger values compared to field test and FEM results. No difference was observed between the response of the SCC and conventional concrete members during the first series of field load tests. © Copyright © 2019 Hernandez and Myers.","diagnostic load test; girder distribution factors; lateral load distribution; load distribution factors; SCC prestressed concrete girders",,,,,,"00040350, ISBN:978-2-35158-156-8, TRyy1236; U.S. Department of Transportation, DOT: DTRT06-G-0014; Missouri Department of Transportation, MoDOT; Missouri University of Science and Technology, MST","The authors gratefully acknowledge the financial support provided by the Missouri Department of Transportation (MoDOT), the National University Transportation Center (NUTC) at the Missouri University of Science and Technology (Missouri S&T), and the U.S. Department of Transportation.

However, to the knowledge of the authors, the analysis and the performance comparison between the two amplifiers was not frequently reported, which is instrumental in realizing and selecting the displacement amplifiers in the practice application. To this end, the two types mechanisms are analyzed and compared with a compliance matrix based model. Via the analysis and comparison, some interesting results which are significant for the amplifiers are founded: 1).

Back filling of foam concrete behind abutment is a good method of treatment. In this study, a kind of high-strength foam concrete was designed for back filling of transition section of road and bridge, and the mechanical properties of the transition section of road and bridge were analyzed using finite element analysis method. It was found that only a large number of micro cracks grew in high-strength concrete under a large number of load cycles, and structural damage did not happen, indicating the high-strength foam concrete had high strength and long service life; the static base pressure was about 40 kPa, indicating a small burden on the structure. Under the vehicle load, the vertical displacement of the transition section of road and bridge with back filling of high-strength foam concrete behind abutment was about 0.7 m and the maximum vertical stress was about -40 kPa, which was significantly lower than that of the ordinary concrete, and the stability was favourable and the settlement was small, indicating that the high-strength foam concrete had good vibration absorption effect. The analysis results verifies the value of the high-strength foam concrete as the backfill material of the transition section of road and bridge and proves that it can effectively solve the problem of differential settlement of the transition segment of road and bridge, providing some theoretical bases for its application and popularization. © 2019, Gruppo Italiano Frattura.

Material characterization studies have quantified fracture behavior, while large-scale experimental tests have demonstrated large critical crack lengths. Early testing focused on demonstrating the extreme potential of high-toughness materials. Recently, a test program utilizing large-scale specimens aimed to identify the toughness level appropriate for steel bridge design of structures traditionally classified as fracture critical. The work resulted in the concept of an integrated fracture control plan (FCP), combining the intent of the original AASHTO FCP from 1978 with modern advances in steel production, analysis, and understanding of fracture mechanics. An integrated FCP prevents fracture through a series of interrelated components, which influence each other in a rational and quantifiable way. The project was comprised of material characterization, full-scale fracture testing of steel bridge components, three-dimensional finite-element analysis (FEA), and an analytical parametric study. Large-scale flexure test results, which included both traditional and high-toughness materials, are presented. Results suggest historical large-scale fracture testing practices may result in critical crack lengths larger than would be expected in service due to the generation of high compressive residual stresses at the crack tip after unsuccessful fracture attempts on a given specimen. Further, fracture toughness demands calculated using FEA compared well with material characterization testing. Results indicated that fracture toughness values indirectly obtained from large-scale experiments should be calculated using FEA. Ultimately, the high-toughness steels tested demonstrated greatly improved fracture performance. High-toughness material, examined at a Charpy V-notch (CVN) impact energy of 170 J (125 ft-lbf), exhibited a 285% increase in critical fracture toughness as compared with a material with over twice the impact resistance of the current specification. © 2019 American Society of Civil Engineers.","Charpy V-notch (CVN); Fracture; Fracture critical; High-performance steel; Toughness","Bridge components; Crack tips; Fatigue crack propagation; Fracture; Fracture testing; Microalloyed steel; Residual stresses; Scale (deposits); Software testing; Steel bridges; Steel testing; Steelmaking; Toughness; Charpy v notches; Critical fracture toughness; Fracture toughness values; High compressive residual stress; High performance steel; Large-scale experimental tests; Material characterizations; Three dimensional finite element analysis; Fracture toughness",,,,,,,,,,,,,,,,"(1978) Guide Specifications for Fracture Critical Non-redundant Steel Bridge Members, , AASHTO.

A dynamic load coefficient of aircraft loading was first developed considering deck pavement roughness and aircraft lift force. The in situ responses of taxiway bridges under 10 aircraft were collected using instrumentation system with acceleration sensor, strain sensor, and inclinometer. The modal frequency, strain influence lines, and deflections of taxiway bridge were obtained from FE analysis and in situ test. An optimization objective function in terms of fundamental frequency and strain influence lines was formulated to ensure convergence and effectiveness in the model updating process, wherein the bending stiffness, density and boundary conditions of the structures are selected as the design variables. The weighted-average method of model updating parameters was proposed considering the differences in the obtained parameters under different loading conditions. The analysis results of updated FE model were validated using static loading test conducted on taxiway bridge. Finally, the proposed virtual load rating method was applied to Taxiway Bridge V in Guangzhou Baiyun International Airport (CAN). © 2019, Korean Society of Civil Engineers.","aircraft operation; finite element updating;

However, the increase in frequency makes the leakage inductance parameter of the transformer in the switching power supply more and more important to the performance of the circuit. In this paper, the leakage inductance and winding loss of high frequency transformer in LLC resonant converter are analyzed in detail. An optimized design scheme of high frequency transformer based on winding structure is introduced, which can effectively reduce the leakage inductance and winding losses of high frequency transformer, and improve stability and efficiency of the transformer resonant converter.

The magnetic bus is used to couple energy systems through the magnetic flux, similar to the capacitive bus widely used in DC microgrids. In systems connected to the distribution grid, galvanic isolation is indispensable and the magnetic coupling brings in addition to this advantage the possibility of interconnecting energy sources with different voltage levels. Its applications range from microgrids to solid-state transformers, with multi-port converters, derived from Dual Active Bridge, as the primary choices for powering systems with high-frequency magnetic coupling. Four pot-core based geometries were proposed and the results obtained by finite element method, showed that they have as advantages compared to core geometries commonly used (shell type, core type and matrix type). These advantages are a lower leakage inductance, higher coupling factor, higher magnetizing inductance and lower core losses. © 2019 IEEE.","MAB converters; Magnetic bus; Magnetic cores; Solid state transformer","Distributed power generation; Electric power system interconnection; Geometry; Inductance; Magnetic cores; Magnetic couplings; Power electronics; Different voltages; Dual active bridges; Galvanic isolation; High frequency HF; High frequency operation; Leakage inductance; Magnetizing inductance; Solid state transformer (SST); Magnetism",,,,,"Coordenação de Aperfeiçoamento de Pessoal de Nível Superior, CAPES; Conselho Nacional de Desenvolvimento Científico e Tecnológico, CNPq; Financiadora de Estudos e Projetos, FINEP","ACKNOWLEDGMENT The authors would like to thank the Brazilian agencies CNPq, CAPES and FINEP for the financial support, and the INEP - Power Electronics Institute for the technical support.

The new generation of young research workers is capable to contribute to the solution of the problem with new findings. The contribution is devoted to the modeling of the vehicle motion along a two-span bridge in the environment of the program system ADINA. The task is solved as a plane problem. It described the creation of a discrete computational model of vehicle with 8 degrees of freedom. The bridge is modeled using beam elements. It is assumed that the vehicle enters the bridge already vibrant. The vehicle and bridge response is modeled when vehicle driving at the speed of 70 km/h. The time course of oscillation of vehicle model's characteristic points and the oscillation of mid spans of individual bridge fields are shown graphically. Important results are given in numerical form.

Many previous studies have highlighted the effects of single in-plane loads on plate buckling but only a few works concentrated on the combined effects. For this reason, the stability of steel plates subjected to the combined action of patch loading, bending moment, and shear stress was studied through parametric analysis in this work. In particular, the effect of patch loading length combined with bending and shear stress was investigated. Other parameters like patch loading magnitude, panel aspect ratio, and plate slenderness have also been considered to characterize the plate stability. Through an intensive finite element method (FEM) analysis, new design equations have been defined to describe the influence of plate and load parameters on critical buckling loads of plates subjected to combined loads, with regard to plates subjected to patch loading. A comparison with the FEM results offers good accuracy, with a maximum deviation equal to 5%. To validate the analytical equations, a practical example is given. © 2019, Zhejiang University and Springer-Verlag GmbH Germany, part of Springer Nature.","Elastic stability; Finite element method (FEM) analysis; Patch loading; Steel bridges erection; TU39","Aspect ratio; Bending moments; Finite element method; Loads (forces); Plates (structural components); Shear flow; Shear stress; Steel beams and girders; Stress analysis; Analytical equations; Critical buckling loads; Elastic stability; Finite element method analysis; Parametric -analysis; Patch loadings; Plate slenderness; TU39; Loading",,,,,,,,,,,,,,,,"Alinia, M.M., A study into optimization of stiffeners in plates subjected to shear loading (2005) Thin-Walled Structures, 43 (5), pp. 845-860; Alinia, M.M., Moosavi, S.H., Stability of longitudinally stiffened web plates under interactive shear and bending forces (2009) Thin-Walled Structures, 47 (1), pp. 53-60; Basler, K., New Provisions for Plate Girder Design.

This NA shift occurs due to non-linear material behaviour (softening, cracking, etc.). The proposed formulation is based upon a modified corotational approach. It has been developed specifically for structures subjected to severe fires, although it is also applicable to the non-linear analysis of structures such as wind towers and bridge decks where the position of the neutral axis in a beam section changes due to material nonlinearity. The analysis formulation results in lower computational effort relative to contemporary analysis methods employing shell or volume elements, while providing comparable results. Four case studies that include material nonlinearity, large deflections and geometric nonlinearity are included to validate the proposed formulation, and results are compared to shell element models analysed using Abaqus. The contributions of this paper are: (a) the application of standard Euler beam theory in a novel manner to allow for adjusted position of neutral axes in beams, (b) the presentation of simple case studies that can be used for validating finite element methods, but which incorporate material, geometric and cross-sectional non-linearity, and (c) illustrating the influence of cross-sectional discontinuity and how it may influence results when using beam elements. © 2019 Elsevier Ltd","Centroid; Composite stiffness; Finite element; Non-linear; Variable neutral axis","Computation theory; Application of standards; Centroid; Composite stiffness; Corotational approach; Geometric non-linearity; Material non-linearity; Neutral axis; Non linear; Finite element method; composite; finite element method; nonlinearity; stiffness; structural component",,,,,,,,,,,,,,,,"(2014), BS EN 1993-1-1:2005 + A1:2014 - Eurocode 3: Design of steel structures - Part 1-1: General rules and rules for buildings.

The Al load cell was designed with a rectangular shape, and the load was concentrated in the lower beam part of the load cell because of the anisotropic thickness. From the static analysis, we identified the appropriate location for a Wheatstone bridge circuit consisting of four strain gauges. In addition, the modal and harmonic analyses showed that the vibrational frequencies of the hospital environment do not seriously interfere with the output voltage of the Al load cell. However, random vibrations generated by the movement of the WRMA system on various surfaces severely increase the standard deviation of the measured solution weight by ± 10 g or more. Such vibrational error is too large because the average weight of Ringer’s solution is 30–40 g at the time of replacing Ringer’s solution.

Finite-element analysis (FEA) is a numerical method that is widely applied to concrete structures based on the use of the nonlinear behavior of materials. The challenge of modeling prestressed concrete structures lies in the treatment of the interface between concrete and prestressing tendons. The FEA-modeling technique discussed in this study is based on general-purpose finite-element packages. This study describes FEA of full-scale high-strength self-compacting concrete, HSSCC pre-tensioned T-girders and its comparison with experimental results. Three 9 m length fully pre-tensioned bridge girders, PHSSCC were designed and cast using HSSCC. The girders were instrumented to monitor deflection, pre-tensioned losses, tendon, steel bar, and concrete strains. The girders were then load tested (until failure), predominantly under flexure, and their service and ultimate results including cracking, flexural stiffness, flexural strength, and different ductility indexes were investigated and compared with FEA results. The software package ABAQUS was used to simulate girders and their bonding conditions to verify the accuracy of FEA. A very good agreement was achieved for numerical and experimental crack patterns. The comparison of finite-element modeling (FEM) and experimental results of load-upward and downward deflections indicated satisfactory agreement throughout the load history of the beams until failure. Comparing FEM and experimental results, reasonable agreement was observed for the two methods of ductility indexes. Finite-element modeling tends to overestimate stress in prestressed tendons at the ultimate state of specimens. © 2018, Iran University of Science and Technology.","ABAQUS; Ductility; FEA; Flexural; High-strength self-compacting concrete; Pre-tensioned","ABAQUS; Concrete beams and girders; Concrete buildings; Concrete construction; Ductility; High performance concrete; Numerical methods; Prestressed concrete; Self compacting concrete; Wire; Experimental investigations; Finite element packages; Flexural; High strength; Numerical approaches; Pre-tensioned; Prestressed tendons; Software package ABAQUS; Finite element method",,,,,,"Acknowledgements The authors would like to thank Kerman Province State Highway and Transportation officials for their financial support and Arash Ali Heshmati for assisting in the construction of the specimens.

The standard fatigue testing methods are time-consuming and expensive to perform, as a large number of specimens is needed to obtain valid results. The purpose of this paper is to examine a fatigue stress-life predication model of RC beams that are developed with an accelerated fatigue approach. This approach is based on the hypothesis of linear accumulative damage of the Palmgren-Miner rule, whereby the applied cyclic load range is linearly increased with respect to the number of cycles until the specimen fails. A three-dimensional RC beam was modeled and validated using ANSYS software. Numerical simulations were performed for the RC beam under linearly increased cyclic loading with different initial loading conditions. A fatigue stress-life model was developed that was based on the analyzed data of three specimens. The accelerated fatigue approach has a higher rate of damage accumulations than the standard testing approach. All of the analyzed specimens failed due to an unstable cracking of concrete. The developed fatigue stress-life model fits the upper 95% prediction band of RC beams that were tested under constant amplitude cyclic loading. © 2019 by the authors.","Accelerated fatigue; Bridges; Finite element analysis; RC beams; S-N model",,,,,,,,,,,,,,,,,"Badawi, M., Soudki, K., Fatigue behavior of rc beams strengthened with nsm cfrp rods (2009) J.

In order to fulfill the design requirement and to improve the compactness and output directionality of the stage, a series of design processes are presented. In particular, an orthogonal compound bridge-type (OCBT)amplifier is introduced to amplify the displacement of the PEA. It can significantly reduce the height of the stage, leading to a compact design. The design variables are determined by analyzing the mechanism. These design variables are optimized by multi-objective genetic algorithm (MOGA)based on finite-element analysis (FEA). The optimal design results in the stage dimension of 58 × 20 × 15.5 mm3. Performance evaluation is conducted by FEA analysis. Results show that the 1-DOF stage is able to provide a maximum displacement of 181.18 μm, which is more than 12 times the input displacement of PEA. Payload testing results indicate the stage can support a maximum load of about 80 N. © 2018 IEEE.",,"Genetic algorithms; Intelligent systems; Piezoelectric actuators; Compact designs; Compliant stages; Design process; Design variables; Flexure stages; Maximum displacement; Multi-objective genetic algorithm; Vertical direction; Design",,,,,"51575545; Fundo para o Desenvolvimento das Ciências e da Tecnologia, FDCT: 143/2016/A","This work was supported in part by the National Nature Science Foundation of China under Grant 51575545, and the Macao Science and Technology Development Fund under Grant 143/2016/A.",,,,,,,,,,"Tian, Y., Liu, C., Liu, X., Wang, F., Li, X., Qin, Y., Zhang, D., Shirinzadeh, B., Design, modelling and characterization of a 2-dof precision positioning platform (2015) Transactions of the Institute of Measurement and Control, 37 (3), pp. 396-405; Shimizu, Y., Peng, Y., Kaneko, J., Azuma, T., Ito, S., Gao, W., Lu, T.-F., Design and construction of the motion mechanism of an xy micro-stage for precision positioning (2013) Sensors and Actuators A: Physical, 201, pp. 395-406; Ren, G., Zhang, Q., Li, C., Zhang, X., Research on a 3-dof compliant precision positioning stage based on piezoelectric actuators (2017) Intelligent Robotics and Applications, pp. 346-358. , Y.

The vibrations occurred at certain wind speed in the first asymmetric torsional mode. Vibration on the hanger is a phenomenon that often occurs especially if the hanger is I-shaped. There are 3 possible reason of the vibration including Vortex Induced Vibration (VIV), Galloping and Flutter. To investigate the phenomena, a finite element analysis of the hanger was conducted by considering the effect of the axial force to the natural frequency of the hanger. The results of the analysis obtained in the form of the natural frequency of the structure in the first asymmetric torsional mode then compared with the frequency of vortex vibrations. It was found that the natural frequency of the structure corresponds to the vortex vibration frequency, and therefore, the hanger vibrated because of Vortex Induced Vibration (VIV). Several alternative solutions to increase Vortex Induced Vibration (VIV) wind speed were considered including improving the shape of the hanger and increasing the hanger’s stiffness by using cable struts. © BEIESP.","Aerodynamic; Hanger; Natural frequency; Steel arch bridge; Vortex induced vibration",,,,,,,,,,,,,,,,,"Simiu, E., Scanlan, R.H., (1986) Wind Effects on Structures, pp. 198-247. , 2nd edition, John Wiley & Sons; Liu, M.G., Mou, T.M., Hua, X.G., Chen, Z.Q., Flutter, galloping, and vortex induced vibrations of h-section hangers (2012) China: ASCE Journal of Bridge Engineering, pp. 1-9; Xu, Y.L., (2013) Wind Effects on Cable Supported Bridges, pp. 83-103. , China: Wiley",,,,"Blue Eyes Intelligence Engineering and Sciences Publication",,,,,22498958,,,,"English","Int.

This article proposes an appropriate simplified method for static analysis of bi-cable triple-pylon suspension bridges in the conceptual design phase. First, theoretical analysis was performed considering the elastic extension of hangers. And the analytical solutions to cable extension under live-load, dead-load intensity, and the static characteristics were obtained. Second, verification of the accuracy of the analytical solutions was conducted by establishing FEM model of triple-pylon steel-box-girder suspension bridges with main spans from 1500 to 2500 m. The comparative analysis shows that the results of the analytical solutions are in good agreement with the Finite Element Models and of great reference value in the conceptual design phase. © The Author(s) 2018.","analytical solution; bi-cable system; Finite Element Models; geometric non-linear analysis; triple-pylon suspension bridge","Analytical models; Box girder bridges; Cable stayed bridges; Cables; Conceptual design; Static analysis; Suspension bridges; Suspensions (components); Cable systems; Comparative analysis; Conceptual design phase; Elastic extension; Geometric non-linear; Horizontal forces; Static characteristic; Steel box girders; Finite element method",,,,,"National Natural Science Foundation of China, NSFC: 18ZR1441700","The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: Project (51878488) supported by National Natural Science Foundation of China: Study on Bending Effect and Anchorage Performance of CFRP Main Cable of Super Long Span Suspension Bridge.

Although plenty of steel bars with various boundary condition caused huge computation load in numerical simulation, most of them were in different geometric locations while their other configuration was similar, such as temperature, moisture, and concrete composition. In this article, shape-based estimation approach was introduced for simplifying assessment of durability of concrete structures regarding numerical simulation. Based on the same penetration condition and diffusing media, the similarity of geometric configuration was the primary consideration of shape-based estimation and a mathematic model regarding the length of involving outline within a circular region with given radius was proposed. The crossbeam of an aged reinforced concrete arch bridge in coastal area was assessed, based on which shape-based estimation was proved to be applicable by comparing with finite element analysis. An evaluating tools called Weighed Corrosion Index in terms of corrosion degree of rebar in the whole concrete section was proposed and discussed in the application on degradation of concrete members. Moreover, for the purpose of modeling and post-processing, designed rebar within concrete section might not be exactly occupied by the nodes of meshed section and thus, content of aggressive agent cannot be directly obtained. An approach for identifying of rebar position and interpolating the content at rebar position was introduced. © The Author(s) 2019.","Concrete; corrosion; durability; interpolation; shape-based estimation",,,,,,"National Natural Science Foundation of China, NSFC: 51508053, 51608069; National Key Research and Development Program of China, NKRDPC: 2016YFC0701202; Fundamental Research Funds for the Central Universities: 106112014CDJZR200016","The author(s) disclosed receipt of the following financial support for the research, authorship, and/or publication of this article: This article was sponsored by National Key Research and Development Program of China (2016YFC0701202), project supported by the National Natural Science Foundation of China (51508053), project supported by the National Natural Science Foundation of China (51608069), and project support by the Fundamental Research Funds for the Central Universities (106112014CDJZR200016), which were greatly appreciated by the authors.",,,,,,,,,,"Zhu, W., Francois, R., Effect of corrosion pattern on the ductility of tensile reinforcement extracted from a 26-year-old corroded beam (2013) Adv Concrete Construct, 1, pp. 121-136;

In this inverse assessment problem, soil-foundation compliance is often not explicitly considered rigorously during design and/or purely numerical assessment. The present work aims to investigate the correlation between subsoil-foundation stiffness and modal characteristics of bridges, as a means to identify a threshold beyond which rigorous subsoil modelling is a prerequisite for reliable model updating. The second Kavala Ravine Bridge, in Greece, serves as the case study for this purpose for which a reasonably reliable finite element (FE) model is developed and updated based on ambient vibration measurements. Alternative soil profiles and subsequently redesigned foundation systems are then used to examine the effect that the correspondingly variable soil compliance would have on the natural frequencies of the bridge. It is shown that soil stiffness alone is not an adequate proxy to decide on the necessity for subsoil modelling, as the foundation stiffness (particularly in cases of softer soil profiles) tends to balance the dynamic properties of the holistic soil-foundation system. The soil-foundation stiffness is therefore the key parameter that dictates the need for refined modelling of soil–structure interaction in the framework of SI-based model updating. © 2018, © 2018 Informa UK Limited, trading as Taylor & Francis Group.","Bridges; calibration; finite element method; identification; monitoring; soil dynamics","Bridges; Calibration; Finite element method; Foundations; Identification (control systems); Inverse problems; Monitoring; Soil mechanics; Soil surveys; Stiffness; Dynamic characteristics; Dynamic property; Foundation stiffness; Foundation systems; Modal characteristics; Reliable models; Soil dynamics; Soil foundation; Soils",,,,,,,,,,,,,,,,"Pawtucket, RI: Simulia; (2010) Minimum design loads for buildings and other structures, , Reston, VA: ASCE/SEI 7-10, American Society of Civil Engineers; Brincker, R., Ventura, C.E., (2015) Introduction to operational modal analysis, , Germany: Wiley Blackwell; Brincker, R., Zhang, L., Andersen, P., Modal identification of output-only systems using frequency domain decomposition (2001) Smart Materials and Structures, 10 (3), pp. 441-445; Caetano, E., Cunha, A., Gattulli, V., Lepidi, M., Cable-deck dynamic interactions at the International Guadiana bridge: On-site measurements and finite element modelling (2008) Structural Control and Health Monitoring, 15 (3), pp. 237-264; Cauberghe, B., (2004), Applied frequency-domain system identification the field of experimental and operational modal analysis, (PhD thesis).

Step-path failure is a typical type of instable mode of man-made and natural rock slopes. The continuum finite element method was applied to work on deeper insight into the propagation of tensile cracks which developing in the intact rock bridges that can finally coalesce to form step-path failure. In this paper, based on the intact rock fracturing hypothesis, two selected slope simulations from the Handlebar Hill open - pit mine near Mt. Isa in Queensland, Australia, modeled the process of fracturing and step-path failure through different pre-existing discontinuities. The empirical models of Bobet and Einstein (1998) and the progressively cracks development are observed within crack initiation, propagation and coalescence in the intact rock bridges. Proposed slope models of the mine included four joint-net distributions through the rock masses considering the geometry of structures (dip angles, spacing, lengths and orientation) illustrated the extension cracks from the flaw tips and propagated to the slope surface. Modes of intact rock bridges fracturing (shear, tensile and a combination of shear and tensile) have been observed. Tensile fracture is usually generated when the rock bridge angle is sub-vertical. Shear fracture can be initiated in less steep rock bridge angles. A combination of shear and tensile failure is normally generated in slopes with. Slope with explicit large-scale structures of steeper dip angles increased the yielding. Larger structures show much higher potential for yielding as the tensile stresses increasing. Major joint plane spacing resulted in less potential for relative deformations between neighboring structures and consequently reduced slope instability. The changes of length and spacing have more influence on slope stability than a change in the dip angle of the structures. © 2019, Springer Nature Switzerland AG.","Rock bridges; Rock slope stability; Shear cracks; Step-path failure; Tensile cracks","Coalescence; Cracks; Fracture; Open pit mining; Rock mechanics; Slope stability; Soil structure interactions; Soils; Instability modes; Large scale structures; Modelling and analysis; Net-distribution; Relative deformation; Slope instability; Tensile failures; Tensile fractures; Rocks",,,,,,,,,,,,,,,,"Baczynski, N.R.P., STEPSIM4 “Step-path” method for slope risks.

Sometimes this torsional moment can create excessive rotation on the exterior girder in the transverse direction, leading to thin deck, reduced concrete cover, and potential maintenance problems in the service stage. Permanent and temporary diaphragms are widely used in wide flange steel girder bridges to resist these loads and subsequent transverse rotation of the exterior girders. However, those diaphragms are generally designed for resisting lateral wind loads, improving vertical loads distribution, and creating lateral stability during construction, which often results in insufficient bracing for reducing the exterior girder rotation. In this study, the effective diaphragm depth, which is determined based on the size of diaphragm and the type of girder to diaphragm connection, was introduced to determine the minimum diaphragm size in order to limit the distortion of the girder web during the bridge overhang construction. A parametric study was conducted to evaluate the significance of different bridge geometries using finite element analysis. The result shows that the diaphragm depth and spacing, as well as girder section, and overhang width, are the most important parameters that affect the exterior girder rotation. To evaluate the relationship among those parameters, around three thousand finite element models were built in SAP2000 using the bridge modeling computer program developed in this study. Finally, a simple method to determine the maximum diaphragm spacing to limit the exterior girder rotation was developed. This method uses the combination of primary curves and modification coefficients based on the girder section and overhang width. © 2019 American Society of Civil Engineers.",,"Beams and girders; Bridges; Construction equipment; Finite element method; Rotation; Structural dynamics; Well spacing; Diaphragm design; Finishing equipment; Girder rotations; Lateral stability; Maintenance Problem; Modification coefficient; Steel girder bridge; Unbalanced loads; Concretes",,,,,,,,,,,,,,,,"Ashiquzzaman, M., Calvo, C.M., Hui, L., Ibrahim, A., Lindquist, W., Hindi, R., Effectiveness of different bracing systems to prevent exterior girder rotation during bridge deck construction (2017) Engineering Structures; Ashiquzzaman, M., Hui, L., Schmeltz, J., Merino, C., Bozkurt, B., Ibrahim, A., Lindquist, W., Hindi, R., Effectiveness of exterior beam rotation prevention systems for bridge deck construction (2016), 16, p. 112. , FHWA-ICT-16-015; Fasl, J.D., The influence of overhang construction on girder design (2008) University of Texas at Austin; Illinois Department of Transportation.

Recently, structural health monitoring (SHM) has obtained a significant contribution in preparing information related to structural behavior during functional life. Though, determining real infrastructure's behavior is intricate, since it relies on structural parameters that cannot be obtained directly from observed data and such identification is prone to uncertainties. Finite element model updating (FEMU) is an approach to address this issue. The current study employs a Modular Bayesian approach (MBA) to update a finite element model (FEM) of a lab-scaled box girder bridge applying natural frequencies. This approach is performed in two stages as undamaged and damaged. These stages can be denoted as the change in structural parameters due to incidences such as impact or fatigue effect. The performed MBA deals with uncertainties thoroughly in all steps. In this study, a discrepancy function is applied to detect the discrepancy in natural frequencies between the FEM and the experimental counterpart. A Gaussian process (GP) is used as a metamodel for the simulated model and the model discrepancy function. In this research, updating the initial FEM of the lab-scale Box Girder Bridge (BGB) by calibrating multi parameters is highlighted. Results specify a considerable drop in stiffness of concrete in damaged phase which is well matched with the cracks observed on the structure's body. Also, discrepancy records reach satisfying range in both stages which implies the structure's properties are predicted accurately. © 2019 9th International Conference on Structural Health Monitoring of Intelligent Infrastructure: Transferring Research into Practice, SHMII 2019 - Conference Proceedings.

This paper presents a parametric investigation of the influence of railing stiffness on the wheel load distribution in simply-supported, two-equal-span, and one- and two-lane reinforced concrete slab bridges using the finite-element analysis (FEA). A total of 160 bridge cases were modeled and bridge parameters such as span lengths and slab widths were varied within practical ranges. Various railing stiffness were investigated by assuming railings built integrally with the bridge deck and placed on both edges of the bridge. The FEA wheel load distribution and longitudinal bending moments were compared with reference bridge slabs without railings as well as to the AASHTO design procedures. Accordingly, the presence of railings reduced the FEA negative moments by a range of 54% to 72% and the FEA positive moments by a range of 40% to 61% depending on the railing stiffness. This reduction in slab moments due to the presence of railings could be considered an increase in the bridges load carrying capacity. The results of this investigation will assist bridge engineers in better designing and/or evaluating concrete slab bridges in the presence of railings. This could also be considered an alternative for strengthening existing concrete slab bridges.

However, steel tub girders possess a relatively low torsional stiffness during construction due to the thin-walled open section that is susceptible to stability issues. Top flange lateral bracing, in the form of a horizontal truss, is installed along the entire length of the steel tub girder to increase the torsional stiffness of the girder. Internal K-frames are placed to control cross-sectional distortion.

Typical steel structures are bridges, transmission line towers, and conveyer-supporting frames. As corrosion-related problems and accidents have been frequently reported in recent years, the need for identifying the health condition of structures has increased. In this context, the axial compressive strength of corroded steel shapes is investigated with experiments and non-linear finite element analyses. The results indicate that the behavior of the corroded members depends strongly on the degree of corrosion and shows global flexural buckling, local buckling, section yielding, and combined failure modes. A strength formula considering the interaction between global and local buckling is proposed, showing that it can reasonably be used for estimating the strengths of corroded steel shapes. © SDSS 2019 - International Colloquium on Stability and Ductility of Steel Structures.",,"Atmospheric corrosion; Buckling; Compressive strength; Ductility; Steel structures; Axial compressive strength; Degree of corrosion; Global and local buckling; Global flexural buckling; Improper maintenance; Non-linear finite-element analysis; Strength formulas; Transmission line towers; Steel corrosion",,,,,,,,,,,,,,,,"(2016) North American Specification for the Design of Cold-Formed Steel Structural Members, , AISI American Iron and Steel Institute Washington, D.C.: AISI; Beaulieu, L.V., Legeron, F., Langlois, S., Compression strength of corroded steel angle members (2010) Journal of Constructional Steel Research, 66, pp. 1366-1373; Oszvald, K., Dunai, L., Effect of corrosion on the buckling of steel angle members - Experimental study (2013) Periodica Polytechnic, Civil Engineering, 56 (2), pp. 63-75; Oszvald, K., Tomka, P., Dunai, L., The remaining load-bearing capacity of corroded steel angle compression members (2016) Journal of Constructional Steel Research, 120, pp. 188-198; Hisazumi, K., Kanno, R., Tominaga, T., Imafuku, K., Axial compressive strength of severely corroded channel and angle members used in truss structures (2014) The 7th European Conference on Steel and Composite Structures: EUROSTEEL'2014, pp. 393-398. , Naples, Italy; Hisazumi, K., Kanno, R., Tominaga, T., Local buckling strength of corroded angle and channel steel shapes and its evaluation using effective width theory (2018) The Ninth International Conference on Advances in Steel Structures: ICASS2018, , Hong Kong, China",,,,"Structural Stability Research Council (SSRC)","2019 International Colloquium on Stability and Ductility of Steel Structures, SDSS 2019","11 September 2019 through 13 September 2019",,152491,,,,,"English","SDSS - Int.

During subsequent inspections, it was found that the material properties of these bridge girders are unclear. There are several bridges in Alberta that have the similar structural design, so the scope of this project is to investigate the damage and give a good understanding of why this bridge�s girders deteriorated so quickly. The first stage of this project is to use the original properties of the damaged girder to calculate moment capacity of the �as new girder�. VecTor2 is used to calculate the moment capacity of the original girders. This finite element modeling program can give reaction forces as an output with a corresponding failure mode. Later on, experimental testing will be carried out on these 9 damaged girders to assess the failure modes. Each girder tested using a flexure cracking test to determine the actual capacity. All girders are simply supported on 4 steel pedestals with electrometric bearing pads. In order to achieve 4-point bending, a spreader beam is placed on top of the experimental girder to distribute the forces from hydraulic actuator. The experimental result will be compared with the modeling data to see how the deterioration affected the capacity of these girders. The finite element modelling method showed a capacity of 1358 KNm for the ""as new girder"". The girder fails in flexure and concrete crushed after steel yields. This capacity data provided by VecTor2 gives a good understanding of how these girders will perform under testing. � 2019 Canadian Society for Civil Engineering.

This paper presents a method to calculate the dynamic bow crushing forces using simplified analytical procedures taking into account the variation of the crushing velocity during impact. Firstly, a non-linear finite element method is applied to simulate the dynamic as well as the quasi-static crushing process of the large scale quasi-static bow crushing experiments performed by Yamada and Endo (2005). The dynamic crushing force-displacement relations, the strain rates and the energy absorption of the bow models are evaluated. An empirical relation is derived between the actual crushing velocity and the strain rates in the bow structure. For different ship impact velocities and impact masses, the dynamic impact results are compared with the experimental static crushing results. It is observed that for realistic velocities and masses the crushing forces and energy absorption of the bulbous bow structure is increased significantly due to the dynamic effects. Secondly, an analytical procedure is presented which is based on a quasi-static simplified calculation method modified by the derived relation between actual deformation velocity and the strain-rates. The varying crushing velocity is determined by an energy based procedure to give consistent estimates of the dynamic bow crushing forces. Finally, the simulated numerical non-linear finite element dynamic and static crushing responses are compared with the results of the presented simplified analytical method. © 2019 by the International Society of Offshore and Polar Engineers (ISOPE).","Bulbous bow; Crushing force; Dynamic and static crushing; Finite element method; Ship collision; Simplified analytical method","Arctic engineering; Energy absorption; Finite element method; Numerical methods; Offshore oil well production; Ships; Strain rate; Velocity; Bulbous bow; Force-displacement relations; Non-linear finite elements; Nonlinear finite element method; Offshore installations; Ship collision; Simplified analytical methods; Simplified calculation method; Crushing",,,,,,,,,,,,,,,,"Abramowicz, W., Crushing Resistance of T, Y and X Sections (1994) Mit-Industry Joint Program on Tanker Safety, , Massachusetts Institute of Technology, USA, Report No. 24; Amdahl, J., (1983) Energy Absorption in Ship-Platform Impacts, , phD Thesis.

The viaduct is located in Central Italy and is founded on piles in an eluvial-colluvial soil deposit. Experimental modal properties are evaluated by means of the operational modal analysis on accelerometric data from ambient excitation and the role of soil-structure interaction in the interpretation of tests is investigated by means of a refined finite element model of the viaduct. In the soil-structure interaction models the local site condition in correspondence of each bridge piers (resulting from geotechnical and geophysical investigations) are considered in the definition of the soil-foundations compliance. Comparison between the experimental and numerical results highlight the role of the pile-soil-pile interaction, the radiation problem, the pile cap embedment and the variability of the soil stratigraphy along the longitudinal direction of the viaduct in the interpretation of the experimental data. © 2019 The authors.","Dynamic identification; Finite element model; Operational Modal Analysis; Reinforced concrete viaduct; Site response; Soil-Structure Interaction","Computational methods; Earthquake engineering; Engineering geology; Finite element method; Geophysics; Modal analysis; Reinforced concrete; Soil structure interactions; Soil testing; Soils; Stratigraphy; Structural dynamics; Ambient excitation; Dynamic behaviours; Dynamic identification; Local site condition; Longitudinal direction; Operational modal analysis; Pile-soil-pile interaction; Site response; Piles",,,,,,,,,,,,,,,,"Omenzetter, P., Beskhyroun, S., Shabbir, F., Chen, G.W., Chen, X., Wang, S., Zha, A., (2013) Forced and Ambient Vibration Testing of Full Scale Bridges, , A report Earthquake Commission Research Foundation Project UNI/578; Zonta, D., Glisic, B., Adriaenssens, S., Value of information: Impact of monitoring on decision-making (2014) Struct.

Hence, it is necessary to consider the soil and structure interaction when we design a bridge subjected to dynamic loading. In this study, the ABAQUS finite element program is used to analyze the performance of bridge pier under soil and structure interaction. The finite element model of soil adapted the soil spring built upon the empirical equation proposed by API. To verify the feasibility of the soil spring model, the results of the nature frequency between the sandbox test and ABAOUS analysis are compared. It has been demonstrated that ABAQUS can solve the natural frequencies and vibration modes of bridge piers reliably. In addition, the displacement responses under earthquake between the sandbox test and soil spring model are compared and good agreement is obtained. Finally, a realistic highway bridge in Taiwan subjected to earthquake is analyzed and important conclusions are given. © 2019 by the International Society of Offshore and Polar Engineers (ISOPE).",,"ABAQUS; Arctic engineering; Bridge piers; Dynamic loads; Earthquakes; Offshore oil well production; Soils; Displacement response; Dynamic loadings; Empirical equations; Finite element programs; Nature frequency; Non-linear finite-element analysis; Soil and structure interactions; Static and dynamic loading; Finite element method",,,,,,,,,,,,,,,,"(2014) Planning, Designing, and Constructing Fixed Offshore Platforms-Working Stress Design, , 22nd Edition; Baguelin, F., Jezequel, J.F., Shields, D.H., (1978) The Pressuremeter and Foundation Engineering, , Transtech Publications, Clausthal, Germany; Chang, Y.L., (1937) Discussion on “Lateral Pile-Loading Tests” by Feagin, LB, Trans.

It is a fully printed pressure sensor fabricated using a combination of digital light processing (DLP)-based printing and screen-printing technologies, with the advantages of high manufacturing efficiency and low cost. The pressure sensor consists of a sensor substrate with a circular diaphragm and a Wheatstone bridge on the surface. First, the pressure sensor was theoretically analyzed and then verified using the finite element method (FEM). During fabrication, the sensor substrate was made from a transparent high-temperature resin, which was printed by a DLP-based 3D printer. The resistors and leads of the Wheatstone bridge were made from carbon paste and silver paste, respectively, and printed by screen-printing technology. Then, the resistors were characterized to find the gauge factor and the print consistency between different resistors. Next, the experimental setup was established for the characterization of the pressure sensor. Three loops of pressurization and depressurization from 0 kPa to 2.4 kPa were applied to the pressure sensor continuously, and the output voltage was recorded. The experimental results show that the gauge factor of the carbon resistor is 17.01 ± 1.85, the sensitivity of the sensor is 4.5522 mV/kPa/5 V, the linearity error is 2.077% FS, the hysteresis error is 6.327% FS and the repeatability error is 5.708% FS. Also, it is very convenient to obtain pressure sensors with different sensitivities and measurement ranges by changing the thickness of the circular diaphragm. All these results prove that the proposed sensor provides a low cost and high sensitivity approach for micro-pressure measurement, and that 3D printing can be applied to the production of personalized sensors. © 2019 IOP Publishing Ltd.","3D printing; digital light processing; micro-pressure sensor; screen printing","Bridge circuits; Carbon; Costs; Errors; Gages; Microsensors; Pressure sensors; Resistors; Screen printing; Substrates; 3-D printing; Circular diaphragms; Depressurizations; Digital light processing; Manufacturing efficiency; Micro pressure sensors; Screen printing technology; Wheatstone bridges; 3D printers",,,,,,,,,,,,,,,,"Eaton, W.P., Smith, J.H., Micromachined pressure sensors: Review and recent developments (1997) Smart Mater.

Owing to its special structure and motion forms, coupling magnetic fields are generated inside the motor, which links with the main magnetic field and results in low speeds and high fluctuations. In this paper, a three-dimensional finite element model of the two-degree-of-freedom direct drive induction motor is developed to determine the rotary coupling magnetic field and its effect on the motor. The distribution of the rotary coupling magnetic field is calculated qualitatively based on a simplified model, and its variation law is investigated based on the changes of the induced voltages in a special coupling model. Moreover, the relationship between the rotary coupling magnetic field and the motor speed is determined by the rotary coupling coefficient. A test platform is applied to verify the coupling model and its results. © ACES","Coupling magnetic field; Induced voltages; Three-dimensional finite element model; Two-degree-of-freedom","Composite bridges; Degrees of freedom (mechanics); Electric drives; Finite element method; Magnetic fields; Coupling coefficient; Direct-drive induction motors; Induced voltages; Magnetic field characteristic; Main magnetic fields; Special structure; Three dimensional finite element model; Two-degree of freedom; Induction motors",,,,,"National Natural Science Foundation of China, NSFC: 51277054, 51777060; Natural Science Foundation of Henan Province: 162300410117","The authors thank the National Science Foundation of China under Grant No. 51777060 and No. 51277054, and the Henan Natural Science Foundation of China under Grant No. 162300410117 for supporting this work.",,,,,,,,,,"Sato, Y., Development of a 2-degree-of-freedom rotational/linear switched reluctance motor (2007) IEEE Transactions on Magnetics, 43 (6), pp. 2564-2566. , June; Li, S.Y., Cheng, K.W.E., A new two-degree of freedom switched reluctance motor for electric vessel (2015) Proceedings of 2015 6th International Conference on Power Electronics Systems and Applications (PESA), pp. 1-6. , Hong Kong,.

The finite element method is adopted to analyze the interaction between ship and floating ice including the coupling effect between ice and water. Based on the comparison between the sea ice test data and the numerical simulation of the ice model, it is verified that the numerical method can successfully simulate the characteristics of sea ice materials. The accuracy of the numerical method is validated against ice tank model test. By using this method, the resistances of a polar ship navigating in floating ice region with different ice coverage rate (60%, 70%, 80% and 90%) at different speeds are calculated. The results show that the ice coverage rate has a great influence on the ice resistance, and the ice resistance varies with ship speeds. © 2019 ASME.",,"Arctic engineering; Arctic vehicles; Bridge piers; Offshore oil well production; Sea ice; Ships; Coupling effect; Coverage rate; Different speed; Floating ice; Ice materials; Ice model; Ice resistances; Ship speed; Numerical methods",,,,,,,,,,,,,,,,"Yousefi, R., Shafaghat, M., High-speed planning hull drag reduction using tunnels (2014) Ocean Engi-neering, 84, pp. 54-60; Von Bock und Polach, R.U.F., Impact of heave and pitch motions on ships in ice 20th IAHR International Symposium on Ice, 2010 (IAHR2010-101), , in Which City This Symposium Was Held, and the Dates; Karulin, E.B., Karulina, M.M., Numerical and physical simulations of moored tanker behavior (2011) Ship and Offshore Structures, 6 (3), pp. 179-184; Su, B., Riska, K., Moan, T., Numerical study of ice-induced loads on ship hulls (2011) Cold Regions Science and Technology, 24, pp. 132-152; Huang, Y., Li, W., Wang, Y., (2016) Experiments on the Resistance of a Large Transport Vessel Navigating in the Arctic Region in Pack Ice Conditions, 15 (3), pp. 1-6; Ehlers, S., Kujala, P., Optimization-based material parameter identification for the numerical simulation of sea ice in fourpoint bending (2014) Proceedings of the Institution of Mechanical Engineers, Part M: Journal of Engineering for the Maritime Environment, 228 (1), pp. 70-80; Riska, K., (2011) Design of Ice Breaking Ships, , Course Material NTNU; Yang, L., Ma, J., Numerical simulation analysis of collision between ship and ocean platform under ice medium (2008) China Ocean Platform, 23 (2), pp. 29-33; Su, B., Riska, K., Moan, T., A numerical method for the prediction of ship performance in level ice (2010) Cold Regions Science and Technology, 60 (3), pp. 177-188; Timco, G., The mechanical and morphological properties of doped ice: A search for a better structurally simulated ice for model ice basins (1979) Proceeding of the Port and Ocean Engineering under Arctic Conditions (POAC 79), 1, pp. 719-739","Qian, Y.; College of Shipbuilding Engineering, China; email: ntqianyuan@163.com",,"Ocean, Offshore and Arctic Engineering Division","American Society of Mechanical Engineers (ASME)","ASME 2019 38th International Conference on Ocean, Offshore and Arctic Engineering, OMAE 2019","9 June 2019 through 14 June 2019",,154931,,9780791858875,PIOSE,,"English","Proc Int Conf Offshore Mech Arct Eng - OMAE",Conference Paper,"Final","",Scopus,2-s2.0-85075950642

These codes provide specific recommendations for modelling of the welded joints, using simple weld geometries. In this paper, experimental hot-spot strain range results from a full-scale automatically welded K-node test are compared to corresponding finite element models. As part of investigating the automatically welded K-joint, 3D scans of the weld surfaces have been made. These scans are included in the FE models to determine the accuracy of the FE models. The results are compared to an FE model with a simple weld geometry based on common offshore design codes and a model without any modelled weld. The results show that the FE model with 3D scanned welds is more accurate than the two simple FE models. As the weld toe location of the 3D scanned weld is difficult to locate precisely in the FE model and as misplacement of strain gauges are possible, stochastic finite element modelling is performed to analyse the resulting probabilistic hot-spot stresses. The results show large standard deviations, showing the necessity to evaluate the hot-spot stress method when using 3D scanned welds.

To carry out the bridge-radiated noise analysis in assessing environmental impacts, the bridge vibration is regarded as an acoustic source of noise radiation so that the finite element (FE) bridge model combined with the acoustic boundary element (BE) method of spatial noise radiation is adopted in performing acoustical computations. For verification, an in-situ experimental noise measurement of rail box-shaped bridge on the selected metro line of Nanchang Metro is used to evaluate the feasibility of the present hybrid FE-BE approach. In addition, the method of panel acoustic contribution analysis is proposed to assess the noise levels radiated from a single/multi-span box-shaped bridges, respectively. With the present investigations, the multi-span bridges may result in larger structure-borne radiated sound pressure levels at far-fields than a single-span.

This paper describes a high-resolution coupled Eulerian-Lagrangian (CEL) finite element model to evaluate the vulnerability of coastal bridges to wave-induced forces during large storms. The modeling technique was calibrated and shown to be in good agreement with experimental results from a reduced-scale bridge structure tested at the O.H. Hinsdale Wave Research Laboratory at Oregon State University. The high-resolution bridge model was used to simulate the response of common types of bridge structures to hydrodynamic loads under hurricane conditions (i.e. surge height, wave height, and frequency) expected in the Texas-Louisiana coast. Results show that superstructure-substructure connection demands for bridges under wave impact loading are sensitive to the flexibility of the substructure, which has historically been modeled as rigid in flume experiments and computer simulations used to develop current design provisions. © 2019-IOS Press and the authors.

This type of crane is located inside the reactor building of a BWR Nuclear Power Plant. It is important to mention that this analysis complies with the requirements for the renewal of an operating license of a Nuclear Power Plant. The Finite Element Method (FEM) was done with the ANSYS code. The alternating stresses were determined with the equations of Goodman, Gerber, Morrow and Walker. The Miner rule was used to estimate the CUF projected to 60 years. The results showed two critical cases in the bridge girders. These are the test of the crane at the end of an outage and the handling of waste casks. The CUF was calculated for 60 years of operation and its range is between 0.003 to 0.016. This complies with the 10 CFR 54.21 (c) (1) (ii) standard. It shows that the CUF remains less than one. This ensures that the integrity of the structural girders is maintained during an extended period of the operating license. © 2019 The Authors.

In recent years, the bond slip behavior of reinforcing bars in UHPC has received extensive attention. In the previous pull-out tests, it was found that the classical splitting theory still plays role in bond failure modes. In this paper, the pull-out test is simulated by finite element analysis, and it is found that unlike ordinary concrete, UHPC can still hold the load for a period of time after the tensile stress on splitting surfaces reaches the critical value, due to the ductility of the material. It is found from the numerical results that the bonding stresses are not evenly distributed along the steel bar when the pull-out failure occurred. Through theoretical analysis and experimental verification, the maximum bonding force of ribbed reinforcing bars in UHPC is closely related to the material ductility. Based on this, a new theoretical model for calculating the bonding strength of ribbed steel reinforcing bars in UHPC is proposed, and can be used for the design method of urban bridge built with UHPC. © 20th Congress of IABSE, New York City 2019: The Evolving Metropolis - Report.

To obtain the mathematical model, a nonlinear cantilever beam with a tip mass was used. The mathematical model incorporates a nonlinear stiffness matrix of the element due to the nonlinear curvature effect of the beam. To validate the mathematical model, the numerical results were compared with experimental data obtained on a machine adapted from cam test. Five different circular cam profiles with eccentricities of 0.25, 0.5, 0.75, 1.25, and 1.5 mm were used. Vibration data were collected through three accelerometers arranged along the sample.

Many of these are more than a century old, and experience much higher live loads than originally designed. Due to age and new live load criteria, it is often necessary to evaluate the existing load capacity. Despite masonry’s wide use, it is only recently that scientific approaches to design and analysis have been developed, but there is a lack of consensus on the conservativeness, simplifications used, and modelling rigor required. The primary purpose of this study is to compare various analysis methods, evaluating the results from the point of view of structural response, modelling efficiency, and variations in the inputs and assumptions used. The techniques considered include limit analysis using hand calculations, rigid-block analysis, finite element analysis using a smeared crack model, and finite element analysis using a discrete crack model. To demonstrate the methods, a 19th-century two-span stone masonry arch in Troy, NY, USA is used as a case study. The bridge underwent a significant intervention in 1986 in which the infill and spandrel walls were removed and replaced. At the time, the bridge was rated by idealizing the bridge as a series of elastic beams. The compressive stress and percent contact area were limited to allowable design values. A secondary purpose of this research was to compare the results of the elastic analysis with the results of the modern analyses, and to provide an updated load rating. © 2019, International Masonry Society.

Based on the field monitoring data obtained from the load test, the stress response test of the orthotropic steel box girder under wheel loads is performed and the correctness of the vehicle test data obtained from the field monitoring data also have been verified by the numerical results of the finite element model. Based on the Miner linear cumulative damage theory, the S-N curve of the Eurocode3 specification is referenced, and the fatigue life calculation formula of the welded details is determined according to the actual structural features. The fatigue life evaluation of the four typical welded details is obtained. The results indicate that: The load test data is compared and verified by the numerical result of finite element model. The local effect of stress distribution is remarkable. The stress measurement points on the four typical welded details are mainly based on low amplitude stress cycles. Most of the stress ranges are 2-10 MPa, among which the stress range of the welded details at the U-rib butt joint is larger. The fatigue life of welded details in the 14 mm thick top plate is smaller than that of the 16 mm thick top plate corresponding to the fatigue life of the welded details. The rib-to-rib butt welded joints and the openings of the diaphragms were prone to fatigue failure. Among them, the welding details of the 14 mm thick U-rib butt joints first appeared fatigue failure. The arrangement of the diaphragm can effectively increase the fatigue life of the top-U rib weld and improve the fatigue performance at this detail.

In order to minimise the damages brought to the environment, human health and the economic issues, rapid non-destructive detection of pipeline leakage is imperative. In recent works, number of non-destructive testing (NDT) methods was used in detecting this defect in pipeline systems such ultrasonic, magnetic particle inspection, pressure transient and acoustic wave methods. In this study, the acoustic wave method and a modal frequency technique are used to detect leakage in pipeline system. Finite element analysis (FEA) was employed to simulate acoustic wave propagation in fluid-filled pipes with leakage. Furthermore, experimental testing was conducted to validate some of the numerical results. The experiment performed consisted of the measurement of acoustic wave propagation in a straight fluid-filled pipe. The FEA analysis of fluidfilled pipe can be used to simulate the acoustic wave propagation and acoustic wave reflectometry of a fluid-filled pipe with leakage of different using the ACAX element in order for accurate predictions. Also, the measured signal of acoustic wave propagation in pipeline from the experiment can be decomposed and de-noised to identify and locate leakages of different sizes. © 2019 SPIE.","Acoustic Reflectometry; Acoustic Wave Propagation; FEA; Leakage Detection; NDT; Non-Destructive Testing; Time of Flight","Acoustic wave propagation; Acoustic waves; Acoustics; Biological systems; Bridge decks; Damage detection; Finite element method; Health; Leak detection; Nondestructive examination; Particle size analysis; Pipelines; Piping systems; Reflection; Reflectometers; Structural health monitoring; Water pipelines; Acoustic reflectometry; Acoustic wave method; Experimental testing; Leakage detection; Magnetic particle inspection; Non destructive testing; Nondestructive detection; Time of flight; Ultrasonic testing",,,,,"Petroleum Technology Development Fund, PTDF","This research was funded by the Petroleum Technology Development Fund (PTDF), Nigeria.",,,,,,,,,,"(2012) Abaqus 6. 10 User's Documentation, , Getting Started with Abaqus Interactive Edition; Abdullahi, M., Oyadiji, S., Acoustic wave propagation in air-filled pipes using finite element analysis (2018) Applied Sciences, 8 (8), p. 1318; Raichel, D.R., The science and applications of acoustics (2006) Springer Science and Business Media, , Second Edi.

In this study, numerical method for temperature-induced structural strains analysis based on a long-span suspension bridge is investigated. The finite element (FE) models for transient thermal analysis and structural analysis of the long-span suspension bridge are developed, respectively. The variations and distributions of structural temperatures are calculated by applying the thermal boundary conditions on the thermal FE models. Then, structural temperatures are loaded on the structural FE models for structural analysis to obtain the structural strains. The temperature-induced strains of box girder, main cables and towers of the suspension bridge are calculated and analyzed. The results indicated that the temperature effects on the main components of suspension bridge are significant. The structural temperature variations exactly explicate the changes of environmental conditions. The strains of temperature effects not only caused by temperatures of itself, but also the impact of other components. This numerical method can conveniently and effectively calculate the structural temperatures and temperature-induced strains of suspension bridge. © 2019 SPIE.

The heated area undergoes compressive plastic strain and the part gets deformed. This method is usually applied as trial and error for straightening shafts, bridge components, ship structures, etc. The conventional straightening mechanism in industries involves creating thermal gradient mechanism (TGM) and shortening. Many studies have been conducted for bending of thin pipes (at a maximum thickness of 2 mm) with the induction of ""shortening"" by laser. Spot Heating, despite its simplicity, results in very small deformations. The present study aims to increase the deformation in the Spot Heating method so as to extend its use in pipe straightening. To meet this goal, the shortening mechanism is developed through a thick pipe wall by optimizing the heating parameters. CFD analysis of flame flow is carried out to determine the heat flux distribution over the pipe surface. Also, the finite element method and optimization are used to analyze and raise the pipe deformation mechanism. The results indicate a considerable increase in the pipe bending which reduces the stages necessary for the pipe straightening in industries. Furthermore, the appropriate distance for combining the hot spots is also obtained. To evaluate the results, the Spot Heating test is performed, showing appropriate agreement with the simulation results. © AFM, EDP Sciences 2019.","Finite element method; Flame bending; Pipe straightening; Spot Heating","Bridge components; Computational fluid dynamics; Deformation; Heat flux; Heating; Laser beams; Strain; Appropriate distances; Compressive plastic strain; Deformation mechanism; Heat flux distributions; Phase change temperature; Shortening mechanisms; Spot heating; Thermal gradient mechanisms; Finite element method",,,,,,,,,,,,,,,,"Van Gestel, R., Mattheij, S., ASME 1994 International Gas Turbine and Aeroengine Congress and Exposition, pp. 1-9. , Rotor repairs, The American Society of Mechanical Engineers, The Hague, Netherlands, 13-16 June 1994; Poursaeidi, E., Yazdi, M.K., Application of the hot spotting method for the straightening of a large turbine rotor (2017) Int.

Employment of magnetorheological (MR) dampers to realize the vibration smart-control of cable-stayed bridges has become a considerable research topic in recent decades. In this paper, the plane truss finite element model (FEM) of a cable-stayed bridge with MR dampers is established. Fluctuating wind field is generated using the weighted amplitude wave superposition (WAWS) method and Kaimal spectrum, and then the time-history sample curve of wind speed is obtained. Fluctuating wind-induced vibration of the long-span cable-stayed bridge installed with MR dampers is analyzed by linear quadratic regulator (LQR) classical optimal control strategy and LQR tri-state control strategy. After the optimal control force is calculated by LQR classical optimal control strategy, control parameters and the input currents of MR dampers can be determined according to the wind-induced vibration by LQR tri-state control. Results show that longitudinal and vertical wind-induced vibration responses of the box girder of the cable-stayed bridge are reduced obviously when MR dampers are arranged between the box girder and pylons. © 2019 International Institute of Acoustics and Vibrations.

If bridge replacement is not necessary, additional girders are installed. Sometimes, due to erection convenience, the added girders do not replicate the static scheme of the refurbished structure. Such an arrangement requires special attention to preserve structural durability. An example of the inappropriate arrangement of the widening of a Reinforced Concrete Gerber-girder road bridge is presented together with an alternative concept of refurbishment based on the addition of the continuous steel-concrete girders as the outermost ones. The added deck slab connects the added and the existing parts of the structure. Attention is drawn the static analysis of the added deck slab and the inf luence of the added outermost girders that do not replicate the static scheme of the existing ones. Due to different static schemes of the existing and the added girders, the traditional method of the deck slab analysis is inappropriate. The Finite Element 3D model is to be applied to access bending moments in the deck slab spans correctly. It is shown that: a) the analysis of the distribution of the bending moments in the existing and the added slab spans, especially near Gerber-hinges, should be based on the Finite Element 3D modelling; b) the analysis should consider live loads acting on the whole width of the Gerber-hinge span; c) the bending moment distribution in the widened deck slab is sensitive to the distance to the Gerber hinge. © 2019 The Author(s).

The obtained prediction models and the Finite Element Models were used to simulate the long-term behaviour and stress redistribution of the concrete arch bridge. Three-dimensional beam elements simulated the stiffened skeleton and surrounding concrete. Then, a parameters study was carried out to analyse the time-dependent behaviour of the arch bridge influenced by different concrete creep and shrinkage models. The simulation results demonstrate that concrete creep and shrinkage have a significant influence on the time-dependent behaviour of the concrete arch bridge. After the bridge completion, the Comite Euro-International du Beton mean deviation of displacements obtained by 1990 CEB-FIP Model Code: Design Code model and fib Model Code for Concrete Structures 2010 model are 3.4%, 31.9% larger than the results predicted by the modified fib Model Code for Concrete Structures 2010 model. The stresses between the steel and the concrete redistribute with time because of the concrete long-term effect. The steel will yield if the fib Model Code for Concrete Structures 2010 model is used in the analysis. The stresses in a different part of the surrounding concrete are non-uniformly distributed. © 2019 The Author(s).","Analysis; Concrete arch bridge; Creep; Deformation; Finite element; Stress; Time-dependent behaviour","Arch bridges; Arches; Beams and girders; Codes (symbols); Concrete buildings; Concrete construction; Creep; Deformation; Finite element method; Musculoskeletal system; Reinforced concrete; Shrinkage; Stresses; Analysis; Concrete arch bridges; Concrete-filled steel tubular; Long term behaviours; Long-term effects; Stress redistribution; Three dimensional beam; Time-dependent behaviour; Structural design",,,,,"National Natural Science Foundation of China, NSFC: 51778531; Applied Basic Research Key Project of Yunnan: 201801D221223","The China Railway Eryuan Engineering Group Co.

The FEM updating technique is an effective way to obtain the accurate FEM of bridges by minimizing the differences between the measured and analytical features of structure. In this study, the FEM updating technique is implemented to obtain the baseline FEM of a practical bridge oriented to the bearing capacity improvement. Firstly, the detailed damages of this actual bridge were investigated by visual inspections, and the static and dynamic structural characteristics were obtained by carrying out the loading tests. Secondly, the updating parameters were determined by considering the practical damages of this bridge. Finally, the baseline FEM of this bridge, considering the stiffness reduction of structure, was obtained by using the measured structural characteristics. The generated baseline FEM is suitable for the stiffness strengthening of this bridge. © 2019 SPIE.","bearing capacity improvement; Bridges; Finite element model updating; loading tests of bridge; structural optimization","Bearing capacity; Bridges; Stiffness; Structural optimization; Capacity improvement; Evaluation and improvement; Existing bridge; Finite-element model updating; Loading tests; Stiffness reduction; Structural characteristics; Visual inspection; Finite element method",,,,,,,,,,,,,,,,"Mottershead, J.E., Friswell, M.I., Model updating in structural dynamics: A survey (1993) Journal of Sound and Vibration, 162, pp. 347-375; Friswell, M.I., Mottershead, J.E., (1995) Finite Element Model Updating in Structural Dynamics, , Kluwer Academic Publishers; Duan, Z.D., Spencer, B.F., Yan, G.R., Ou, J.P., An improved optimal elemental method for finite element model updating (2004) Journal of Earthquake Engineering and Engineering Vibration, 3 (1), pp. 67-74; Kim, G.H., Park, Y.S., An improved updating parameter selection method and finite element model updating using multi-objective optimization technique (2004) Mechanical System and Signal Processing, 18, pp. 59-78; Linderholt, A., Abrahamsson, T., Parameter identifiability in finite element model error localization (2003) Mechanical Systems and Signal Processing, 17 (3), pp. 579-588; Friswell, M.I., Penny, J.E.T., Garvey, S.D., Parameter subset selection in damage location (1997) Inverse Problems in Engineering, 5 (3), pp. 189-215; Friswell, M.I., Mottershead, J.E., Ahmadian, H., Finite element model updating using experimental test data: Parameterization and regularization (2001) Transactions of the Royal Society of London, Series A: Mathematical, Physical and Engineering Sciences, Special Issue on Experimental Modal Analysis, 359, pp. 169-186","Tan, Z.; Hunan Provincial Communications Planning, 158 Furongbei Road, China; email: shinan_lan@163.com","Lynch J.P.Huang H.Sohn H.Wang K.-W.","OZ Optics, Ltd.;Polytec, Inc.;The Society of Photo-Optical Instrumentation Engineers (SPIE)","SPIE","Sensors and Smart Structures Technologies for Civil, Mechanical, and Aerospace Systems 2019","4 March 2019 through 7 March 2019",,148997,0277786X,9781510625952,PSISD,,"English","Proc SPIE Int Soc Opt Eng",Conference Paper,"Final","",Scopus,2-s2.0-85068323278

Under live load, the longitudinal deflection of the mid-pylon is an important control parameter for a multi-pylon suspension bridge design. It is important to establish a simplified method of calculating pylon deflection for the preliminary design and selection of a multi-pylon suspension bridge. Based on deflection theory and deformation compatibility condition, considering main cable horizontal constraints and the interaction among pylons and girders with the methods of equivalent stiffness and moment distribution, the simplified calculation formulas of pylon displacement at the top for three-, four-, and five-pylon suspension bridges are derived. The validity of the formulas are verified by model experiment, real bridge testing, and finite-element analysis. For a floating system, the error between the simplified formula and the finite element method is less than 10%, and that of the model experiment is within 25%. For a consolidation system, the error between the simplified formula and the finite element method is within 16%, and that of the real bridge testing is less than 11%. As the number of pylons increases, the simplified formulas tend to be less accurate. © National Academy of Sciences: Transportation Research Board 2019.",,"Suspension bridges; Suspensions (components); Control parameters; Deformation compatibility; Equivalent stiffness; Moment distribution; Preliminary design; Simplified calculation formula; Simplified calculations; Simplified formula; Finite element method",,,,,,,,,,,,,,,,"Zhang, J.Q., Qu, Z.L., Song, J.Y., Yang, Y., Overview of Multi-Pylon Multi-Span Suspension Bridge (2011) Journal of Highway & Transportation Research & Development, 28 (9), pp. 30-34; Zhang, J.Q., Zhong, J.C., Yang, Y., (2013) Final Report on the Structural System and Structural Performance of Multi-Tower Suspension Bridge, , Research Institute of Highway, Ministry of Transport, Beijing; Jokilehto, J., (2007) History of Architectural Conservation, , Routledge, London; Yoshida, O., Okuda, M., Moriya, T., Structural Characteristics and Applicability of Four-Span Suspension Bridge (2004) Journal of Bridge Engineering, 9 (5), pp. 453-463; Zhong, J.C., Taizhou Yangtze River Bridge – The First Kilometer Level Three-Pylon Two-Span Suspension Bridge in the World (2011) Engineering Sciences, 9 (2), pp. 2-8; Gao, K.P., Zhang, Q., Tang, H.Q., Yang, G.W., Study of Middle Tower Stiffness of Three-Tower Suspension Bridge of Maanshan Changjiang River Highway Bridge (2011) Bridge Construction, 33 (5), pp. 1-5; Li, C.X., Design of Towers of Yingwuzhou Changjiang River Bridge in Wuhan (2014) Bridge Construction, 44 (5), pp. 94-98; Gao, Z.Y., Shi, F.H., Key Techniques of Design of Main Bridge of Oujiang River North Estuary Bridge in Wenzhou (2017) Bridge Construction, 47 (5), pp. 1-5; Jennings, A., Gravity Stiffness of Classical Suspension Bridges (1983) Journal of Structural Engineering, 109 (1), pp. 16-36; Sato, K., Deflection Theory of Multispan Suspension Bridges Considering Deflection of Towers and Its Numerical Examples of Various Influence Lines (1971) Proc., Japan Society of Civil Engineers, pp. 11-22. , Japan; Wollmann, G.P., Preliminary Analysis of Suspension Bridges (2001) Journal of Bridge Engineering, 6 (4), pp. 227-233; Luo, X.H., Parameter Analysis of 3-Tower Suspension Bridges using Deflection Theory (2008) Building Structure, 38 (9), pp. 100-101. , +60; Luo, X.H., Han, D.Z., Wan, T.B., Deflection Theory and Its Programming for Multi-Tower Suspension Bridges (2008) Bridge Construction, 38 (2), pp. 41-44; Choi, D.H., Gwon, S.G., Yoo, H., Na, H.S., Nonlinear Static Analysis of Continuous Multi-Span Suspension Bridges (2013) International Journal of Steel Structures, 13 (1), pp. 103-115; Jin, B.H., Wang, L.B., Wang, H., Guo, X.Y., Analysis of Static Characteristic Triple-Tower-Four-Span Suspension Bridge by Deflection Theory (2016) Journal of Nanjing Forestry University, 40 (3), pp. 143-148; Wollmann, G.P., Preliminary Analysis of Suspension Bridges (2001) Journal of Bridge Engineering, 6 (4), pp. 227-233; Choi, D.H., Gwon, S.G., Na, H.S., Simplified Analysis for Preliminary Design of Towers in Suspension Bridges (2014) Journal of Bridge Engineering, 19 (3). , p. 04013007","Li, P.; Research Institute of Highway, China; email: pf.li@rioh.cn",,,"SAGE Publications Ltd",,,,,03611981,,TRRED,,"English","Transp Res Rec",Article,"Article in Press","",Scopus,2-s2.0-85067857968

P. 08034, Spain","Currently, one of the most used steel bridge assembly methods is the Incremental Launching Method (ILM). Its practical application consists in passing the bridge assembly through a launching shoe as well as over each support pile. For steel plate girders, a concentrate vertical reaction also known as patch loading is generated over one the flanges when ILM is employed, and depending on the geometrical and material properties of the girder, buckling failure in the web panel may occur. To overcome this type of failure, plate girders are reinforced with longitudinal stiffeners. Therefore, this paper aims at investigating the effect of the bearing length on the elastic buckling behavior of longitudinally stiffened girder webs subjected to patch loading. Buckling coefficients of longitudinally stiffened girder webs are calculated by means of linear finite element analysis. Furthermore, a parametric analysis is performed to study the influence of other geometric parameters such as the panel aspect ratio and the geometrical properties of the longitudinal stiffener on the buckling coefficient. The results show that for longitudinally stiffened girder webs the buckling coefficient increases with the loading length. However, this conclusion is considerably affected by other factors such as the position of the stiffener, and panel aspect ratios. © 2018 Revista Facultad de Ingenieria -redin.","Buckling; Coefficient; Finite element analysis; Longitudinal; Patch loading; Plate girders; Stiffeners",,,,,,,,,,,,,,,,,"(2006) Part 1-5: General rules, , supplementary rules for planar plated structures without transverse loading, ENV 1993-1-5; (2016), Specification for Structural Steel Buildings, ANSI/AISC 360-16 An American National Standard; Rockey, K.C., Bagchi, D.K., ""Buckling of plate girder webs under partial edge loading,"" (1970) International Journal of Mechanical Sciences, 12 (1), pp. 61-76. , Jan; Chin, C.K., Al-Bermani, F.G.A., Kitipornchai, S., ""Finite element method for buckling analysis of plate structures,"" (1993) J.

With the current trend of high-pressure, high-temperature (HPHT) development, the industry is migrating to an era of modern analysis methods with complex material testing programs to assess potential fatigue life impacts due to such high-pressure and -temperature exposures as well. This paper presents an approach and an example of a multiaxial strain-life analysis method that meets the provided HPHT design guidelines of API Technical Report 17TR8. The paper bridges the gap between theory and practicality in strain-life-based fatigue analysis and presents a robust process developed for HPHT nickel alloy components, which are part of the subsea 20,000-psi vertical monobore subsea tree. The endeavor includes strategizing for required material tests in environment, actual material testing, followed by material data processing, which includes statistical corrections and extraction of parameters necessary for efficient fatigue analysis. The components are then analyzed in finite-element analysis (FEA) with typical loading sequences as seen in its life of field. Finally, the FEA results are postprocessed using the critical plane approach for all nodes in the model. The governing equations are presented throughout the analysis to enable readers to develop their own results. The 20,000-psi vertical monobore tree fatigue analysis depends on the operations forecasted for its life cycle. Using the expected load histogram, a series of pressure and thermal analyses were executed to produce cycles to failure. Implementing the Palmgren-Miner's rule enabled obtaining the total damage produced by factory acceptance tests total field life shut-ins, and flow-in pressure cycles. This not only serves as verification that the required safety factor is met per API Technical Report 17TR8 but also enables making engineering assessments of ""what-if"" operations. In this sense, a change or addition of an operation will lead to a simple recalculation of fatigue damage without requiring performing the analysis from the ground up. The method also allows for computation of cycles to failure for a pressure range when the other pressure ranges and conditions don't change. In addition to the life cycle calculation, the method evaluates the damage of all nodes, which produces full-contour plots. The contour plots, in addition to displaying the hot-spot locations, when used with structural analysis results, enable the engineer to assess areas of improvement and product optimization. The method proposed gives an effective way to communicate and recommend the design life capabilities of a product to the operator to predict life expectancy for combinations of expected load scenarios.

A thermo-mechanical analysis is set up for the simulation of the welding procedure and the residual stresses are determined. The finite element model is validated with experimental residual stress measurements with the incremental hole-drilling method and a good agreement is found. Only the transverse direction (perpendicular to the welding direction) is discussed. There are tensile yield stresses present on top of the deck plate and on the longitudinal stiffener in the region near the weld seam which diminish at a greater distance from the welding line.

First, models of probabilistic corrosion due to chloride-induced corrosion are briefly reviewed. Then, FE modeling methods for corroded RC structures are presented, followed by validation with reference to experimental tests. In the methods, concrete and reinforcing steels are separately modeled, and the degradation in mechanical behavior of both components is considered. Finally, as an illustrative case study for the proposed FE analysis, the time-variant structural safety of a box-girder bridge is calculated over its lifetime of 50 yrs.

In particular, the change that the probability of failure undergoes due to changes in the distribution parameters of the uncertain model parameters is utilized as a sensitivity measure. A simulation-based approach that corresponds to a simple post-processing step of an advanced sampling-based reliability analysis is used to perform the sensitivity analysis. In particular, subset simulation, introduced in the previous chapter, is applied in the present formulation. The analysis does not require any additional system response evaluations. The feasibility and effectiveness of the approach is demonstrated on a finite element model of a bridge under stochastic ground excitation. The sensitivity analysis is carried out in a reduced space of generalized coordinates. The computational effort involved in the reliability sensitivity analysis of the reduced-order model is significantly decreased with respect to the corresponding analysis of the full finite element model. The reduction is accomplished without compromising the accuracy of the reliability sensitivity estimates. © 2019, Springer Nature Switzerland AG.",,"Dynamical systems; Finite element method; Probability distributions; Reliability analysis; Stochastic models; Stochastic systems; Uncertainty analysis; Computational effort; Distribution parameters; Generalized coordinates; Probability of failure; Reliability sensitivity; Reliability sensitivity analysis; Sensitivity measures; Simulation based approaches; Sensitivity analysis",,,,,,,,,,,,,,,,"Au, S.K., Reliability-based design sensitivity by efficient simulation (2005) Comput.

The concept is based on nonlinear finite element simulations to evaluate the cracking behavior of reinforced concrete structures. Here, the crack width at the reinforcement layers is used as an indicator for corrosion vulnerability. The structural durability is optimized by minimizing the exposed lateral surface of reinforcement bars.Within the optimization, uncertain a priori parameters (structural loading, material properties) and uncertain design parameters (concrete cover) are considered by means of stochastic distributions and intervals, respectively. To solve the optimization task, the finite element model is substituted by a numerical efficient surrogate model. As an example, the cracking behavior of a reinforced concrete bridge structure is optimized considering the accepted failure probability with respect to the load bearing capacity as constraint. © 2019 Taylor & Francis Group, London.",,"Concrete buildings; Concrete construction; Corrosion; Durability; Finite element method; Life cycle; Reinforced concrete; Stochastic systems; Uncertainty analysis; Durability simulation; Failure Probability; Load-bearing capacity; Nonlinear finite element simulation; Reinforcement layers; Stochastic distribution; Structural durability; Uncertain design parameters; Structural design",,,,,"Deutsche Forschungsgemeinschaft, DFG: SPP 1886","This research is supported by the German Research Foundation within Subproject 6 of the Priority Programme (SPP 1886) “Polymorphic uncertainty modelling for the numerical design of structures”, which is gratefully acknowledged by the authors.",,,,,,,,,,"Carol, I., Rizzi, E., Willam, K., On the formulation of anisotropic elastic degradation.

Proof load testing is one of the method to test the capacity of bridges by applying loads on the existing concrete bridges with small spans. Because of the fact that neither the actual traffic load nor the design traffic load required by Eurocode can be directly applied on the target bridge in real-life proof load testing, an equivalent wheel load has to be applied instead. The magnitude and the location of the equivalent wheel load is determined in such a way that it generates the same magnitude of inner forces in the cross section. Such calculation is usually done by linear finite element analyses (FEA). Whereas, different bridges have different geometry such as length, width, thickness, skewness, number of spans and lanes etc. For each configuration, FEA has to be done first to determine the loading position. The main aim of this paper is to study the relation between bridge geometry and unfavourable loading positions. Based on that, a guidance tool is developed for the determination of the critical proof load testing locations for the practice. To achieve this goal, a Python script has been developed using the general purpose FEM platform DIANA FEA. The script enables the automatic generation and analysis of a bridge model with different geometries and loading conditions. By applying the Eurocode Load Model 1 (LM1) at variable locations, the most unfavourable loading positions for the proof load are obtained at the corresponding boundary conditions. The output of the study provides a convenient tool for future proof load testing. © 2019 Taylor & Francis Group, London.",,"Codes (standards); Concrete bridges; Concrete testing; Concretes; Finite element method; Geometry; Life cycle; Load testing; Loads (forces); Location; Wheels; Automatic Generation; Bridge geometry; Different geometry; Equivalent wheel loads; Existing bridge; Existing concrete bridge; Linear finite element analysis; Loading condition; Bridges",,,,,,,,,,,,,,,,"Lantsoght, E.O.L., Van Der Veen, C., De Boer, A., Walraven, J.C., Recommendations for the Shear Assessment of Reinforced Concrete Slab Bridges from Experiments (2013) Structural Engineering International, 23 (4), pp. 418-426; (2011), Eurocode 1: Actions on structures Part 2: Traffic loads on bridges; Koekkoek, R.T., Lantsoght, E.O.L., Yang, Y., Hordijk, D.A., (2016) Analysis Report for the Assessment Ofviaduct De Beek by Proof Loading, p. 125. , Stevin Report 25.5-16-01, Delft University of Technology, Delft, the Netherlands; Manie, J., Kikstra, W.P., (2017), DIANA User’s Manual, 10.2, Ed; Casas, J.R., Gmez, J.D., Load Rating of Highway Bridges by Proof-loading (2013) KSCE Journal of Civil Engineering, 17 (3), pp. 556-567; Val, D., Stewart, M.G., Safety factors for assessment of existing structures.

Current design approaches of estimating foundation stiffness include advanced dynamic finite element, distributed spring approach, and lumped spring approach. The aim of this paper is to overview the different methods for computing the foundation stiffness and to check their applicability. This has been done by considering an example: Saraighat Bridge supported on double D shaped caisson foundation. Advanced three dimensional finite element analysis is performed to extract the stiffness (Lateral, rotational, and coupling) of double D foundations and the results are compared to the representative circular foundations. It has been concluded that the stiffness of foundation can be significantly affected by its geometry. Furthermore, the stiffness functions are utilized in computing the fundamental frequency of the bridge and also compared with the frequency obtained from different approaches. The frequency estimated using the present study matches satisfactorily well with the monitored data testifying the validation of the work. © 2019, Springer International Publishing AG, part of Springer Nature.","Caisson Foundations; Circular Shaft; Dimensional Finite Element Analysis; Stiffness Estimation; Stiffness Function","Caissons; Climate change; Pressure vessels; Soil structure interactions; Springs (components); Stiffness; Sustainable development; Underwater foundations; Caisson foundations; Circular foundations; Foundation stiffness; Fundamental frequencies; Soil-Structure Interaction effects; Stability analysis; Stiffness function; Three dimensional finite element analysis; Finite element method",,,,,"Commonwealth Scholarship Commission, CSC: INCN-2016-214; University of Surrey","Acknowledgements.

HCB consists of self-consolidating concrete (SCC) that is poured into classical arch shape and tied at the ends by steel tendons. Both the concrete and the steel are tucked inside a durable fiberglass shell, and the voids are filled with polyiso foam. This paper aims to examine the flexural behavior of an in-service HCB, evaluate the current methodology and assumptions, and propose modifications to that methodology. To achieve these goals, the strains induced in HCB elements due to different loading stages were experimentally measured. Numerical predictions of the strains were performed via the existing methodology, the modified procedure, and a finite element model (FEM) that was constructed using ANSYS V14. The linear FEM predicted the strains with acceptable accuracy. The model clarified that the foam achieves partial composite action between the HCB elements, resulting in a strain incompatibility between them. The current methodology was found to be unable to predict the maximum compressive strain in the concrete arch. The modified procedure is based on the strain compatibility assumption. However, it models the HCBs as curved beam rather than a straight one, using a simplified spring model to represent the beam supports. These modifications achieved significant enhancements in estimating the strains under service loads. © 2019 Mohamed A. Aboelseoud and John J.

In this research, the effect of load distribution factors on the design parameters of bridge superstructures are studied by a numerical semi-continuum method. Three different case studies are carried out in the research to compare the accuracy and performance of the method. The objective of the first case is to control the outcomes of the method with the results of finite element method as well as AASHTO LRFD method. The second case is presented to study the effect of design parameters on load distribution factors between longitudinal girders through the three methods. Finally, a field test investigation is studied in the last case to compare all three methods with an actual field test study. It has been shown that the AASHTO LRFD method is not precise enough in comparison with the present method. The AASHTO LRFD formulas for live load distribution are quite unreliable and can give design parameters far too low or far too high. Moreover, minimum calculation time, convenient performance and high accuracy in the solution process are the other advantages of the method proposed in this research. © 2019, Korean Society of Civil Engineers.","AASHTO LRFD; finite element method; flexural and torsional stiffness; load distribution factors; semi-continuum method","Bridges; Electric power plant loads; Factor analysis; Highway planning; Numerical methods; AASHTO-LRFD; Bridge superstructure; Calculation time; Continuum method; Design parameters; Load distribution factor; Solution process; Torsional stiffness; Finite element method",,,,,,,,,,,,,,,,"(2003) Standard Specifications for Highway Bridges (17Th Edition), , AASHTO, Washington, D.C; (2007) LRFD Bridge Specifications (4Th Edition), , AASHTO, Washington, D.C; Bakht, B., Jaeger, L.G., (1989) Bridge analysis simplified, , McGraw-Hill, New York, NY, USA; Barr, P.J., Woodward, C.B., Najera, N., Amin, M.N., Long-term structural health monitoring of the San Ysidro Bridge (2006) Journal of Bridge Engineering, 20 (1), pp. 14-20; Cai, C., Discussion on AASHTO LRFD load distribution factors for slab-on-girder bridges (2005) Pract.

These properties make them a favorable reinforcement for nanocomposites. Since experimental studies on nanocomposites are time-consuming, costly, and require accurate implementation, finite element analysis is used for nanocomposite modeling. In this work, a representative volume element (RVE) of epoxy/BNNT nanocomposites based on multi-scale modeling is considered. The bonds of BNNT are modeled by 3D beam elements. Also non-linear spring elements are employed to simulate the van der Waals bonds between the nanotube and matrix based on the Lennard-Jones potential. Young’s and shear modulus of BNNTs are in ranges of 1.039-1.041 TPa and 0.44-0.52 TPa, respectively. Three fracture modes (opening, shearing, and tearing) have been simulated and stress intensity factors have been determined for a pure matrix and nanocomposite by J integral. Numerical results indicate that by incorporation of BNNT in the epoxy matrix, stress intensity factors of three modes decrease. Also, by increasing the chirality of BNNT, crack resistance of shearing and tearing modes are enhanced, and stress intensity factor of opening mode reduced. BNNTs bridge the crack surface and prevent crack propagation. © 2019 Polish Society of Theoretical and Allied Mechanics.

These structural members have lesser positive bending moment because of which it has lesser maximum deflection as compared to simply supported beam. Due to advancement in technologies, the continuous beams in bridges have to carry heavy loads, but due to restriction for the depth of the beam, it is required to use reinforced high-performance concrete (HPC) beam instead of normal RC beam. Therefore, the use of HPC beams in these types of structures is beneficial. As compared to simply supported beams, very few experimental studies have been investigated on the behaviour of continuous HPC beams. The objectives of this research are to investigate the behaviour of continuous high-performance concrete beams under flexure and to provide design guidelines to predict the failure load and to compare the experimental values with the analytical and theoretical values. This paper presents the experimental results of two reinforced HPC beams with the rectangular cross section of 230 mm × 150 mm continuous over two spans of 1500 mm each. The beams are designed using ACI-318 and are tested under concentrated monotonic loads applied at the midpoint of each span. Further, the same beams are analysed by finite element method (FEM) using ANSYS software. © Springer Nature Singapore Pte Ltd. 2019.","FEA; Flexural behaviour; HPC two-span","Finite element method; High performance concrete; Reinforced concrete; Experimental values; Flexural behaviour; HPC two-span; Maximum deflection; Rectangular cross-sections; Reinforced concrete beams; Simply supported beams; Theoretical values; Concrete beams and girders",,,,,,,,,,,,,,,,"Aıẗcin, P.C., The durability characteristics of high performance concrete: A review (2003) Cement and Concrete Composites, 25 (4-5), pp. 409-420. , https://doi.org/10.1016/S0958-9465(02)00081-1; Hassan, K.E., Cabrera, J.G., Maliehe, R.S., The effect of mineral admixtures on the properties of high-performance concrete (2000) Cement and Concrete Composites, 22 (4), pp. 267-271. , https://doi.org/10.1016/S0958-9465(00)00031-7.

This damage reduces ultimate strength of the main girders significantly (e.g., in the case of 50%-corroded upper flanges, approximately 30 percent reduction in bending strength). This paper presented a simple evaluation method for estimating the remaining strength of the plate girders that have local corrosion damage under sleepers. Remaining strength of the damaged plate girders can be calculated by taking into account both the remaining strength for local load (hereinafter referred to as “patch load”) that acts directly on the upper flanges under the sleepers, and the remaining strength for bending load that acts on the main beam itself. This new evaluation method using the equations proposed in this paper, is based on the idea that the remaining strength under pure bending load can be obtained as the minimum value of strengths calculated in light of the various buckling modes of the compression flange, while taking the thickness reduction due to corrosion into account. Thereafter, the remaining strength under patch load only can be calculated by using an equation which is further simplified based on Takimoto’s original equation. Finally, the remaining strength of the plate girder as a whole is obtained from the strength interaction curve between patch and bending loads. In addition, by comparing the estimated remaining strengths obtained through this method with those obtained from nonlinear Finite Element Method (FEM) analyses using full-scale beam models, it could be concluded that the simple evaluation method by using both new and original equations can estimate the remaining strength of plate girders with corroded flanges under sleepers with around 95 percent accuracy. © 2019, Korean Society of Civil Engineers and Springer-Verlag GmbH Germany, part of Springer Nature.","bending load; buckling mode; local corrosion; patch load; railway bridge; sleeper","Beams and girders; Compressive strength; Fasteners; Flanges; Localized corrosion; Nonlinear equations; Railroad bridges; Railroads; Steel bridges; Steel corrosion; Bending load; Buckling mode; Local corrosion; Railway bridges; sleeper; Bending strength",,,,,,,,,,,,,,,,"(2010) Abaqus/Cae 6.10 user’s Manual, , https://www.sharcnet.ca/Software/Abaqus610/Documentation/docs/v6.10/pdf-books/CAE.pdf; Basler, K., Thurlimann, B., Strength of plate girders in bending (1961) Proc. of ASCE, 87 (ST6), pp. 153-181; Bergfelt, A., Studies and tests on slender plate girders without stiffeners shear strength and local web crippling (1971) International Association for Bridge and Structural Engineering, pp. 67-83; Bergfelt, A., Hovik, J., Shear failure and local web crippling in thin walled plate girders (1970) Chalmers Univ. of Technology.

Therefore, it has a potential to decrease the life-cycle cost of bridges. To realize the economic benefit of the SHM systems, a bridge management system (BMS) integrating big data of SHM collected continuously from the bridges is proposed in this paper. The BMS includes four modules: Structural inventory, inspection/SHM/finite-element model (FEM), bridge condition assessment, and maintenance decision. The SHM data is utilized in module of bridge condition assessment, which derives a three-dimensional bridge condition rating system. The proposed methodology is expected to assist priority ranking of bridge management activities throughout the bridge’s life time. © Springer Nature Switzerland AG 2019.",,"Big data; Bridges; Condition based maintenance; Costs; Data integration; Information management; Life cycle; Bridge management; Bridge management system; Condition assessments; Economic benefits; Finite element modelling (FEM); Loading response; Management activities; Structural health monitoring systems; Structural response; Uncertainty; Structural health monitoring",,,,,,,,,,,,,,,,"Abe, M., Fujino, Y., (2009) Bridge Monitoring in Japan, , Encyclopedia of structural health monitoring.

This bridge is a strategic access point for the village of Campana both for the common use and for the heavy trucks involved in the construction activities due to seismic event. This ancient bridge was built in order to carry smaller load than current ones. The Campana village Major asked for performing the assessment of the bridge real carrying capacity. The structure is a multi-span arch bridge with 6 arches with a total length of 33 m. The evaluation process is based on CNR guidelines “DT 213/2015” in agreement with the current Italian Technical Code DM 14.01.2008, starting with the experimental testing program in order to get information about the geometric dimensions and the masonries’ mechanical parameters. Two different analysis methods were used in the carrying capacity analysis: (1) Computational limit analysis methods (also known as ‘plastic’ or ‘mechanism’ methods) based on the Heyman hypothesis; (2) Finite element methods “FEM” with 3d FE model discretized with “bricks” elements. The results of the two methods were compared and the “AF” Adequacy Factor was defined.

Because of this fact and the normal decay and damage presented by historical structures, the need of strengthening arises and gives place to proposals such as the one presented in this paper. The objective of this paper is to present the evaluation of the feasibility of the use of an external post-tensioning arrangement to strengthen historical stone masonry bridges. The arrangement proposed is an alternative to those already existent and developed by other authors. To verify the assumed hypothesis, the proposal was analyzed with a general-purpose finite element method software, ANSYS. A qualitative assessment of this and other strengthening techniques available and used nowadays is also presented to evaluate its application suitability to historical structures. The results obtained via simple non-linear FEM models show that the proposal effectively increases the ultimate load capacity of the arch ring. It is also shown that the external post-tensioning arrangement can contain at certain level the horizontal thrust at the abutments. The proposed technique is deemed to be sympathetic and has great potential to be used to repair, strengthen and retrofit historical stone masonry bridges. © 2019, RILEM.","ANSYS; Historical stone masonry bridges; Non-linear FEM; Post-tensioning; Strengthening",,,,,,"Trinity College Dublin, TCD","The authors would like to acknowledge Trinity College Dublin and the Department of Civil, Structural and Environmental Engineering for the support that allowed the completion of this paper.",,,,,,,,,,"O’Dwyer, D., Handouts from the Postgraduate Diploma in Applied Building Repair and Conservation (2017) Trinity College Dublin, Department of Civil, Structural and Environmental Engineering, Dublin, Ireland; Jurina, L., Experimental tests on consolidation of masonry bridges using “RAM-Reinforced Arch Method” (2016) 8Th International Conference on Arch Bridges, Wroclaw, Poland; D’Ayala, D., Fodde, E., (2008) Structural Analysis of Historic Construction: Preserving Safety and Significance: Proceedings of the Sixth International Conference on Structural Analysis of Historic Construction, 2 (19), p. 1574. , 2–4 July, Bath, United Kingdom.

It also helps in making cost effective decision on existing structure regarding replacement or rehabilitation in time. In this study deterministic approach is used for the estimation of fatigue life of a plate girder railway bridge. Finite element analysis is carried out using software to find the critical region of fatigue failure and the stress developed there. Number of cycles of different stress range during the movement of train is evaluated with the help of S-N curve. The S-N curve is selected based on type of welds and type of stress considered. Rain flow counting method is used for evaluating the number of cycles corresponding to each stress range. The fatigue damage is then evaluated by using Palm Miner damage accumulation rule and corresponding fatigue life is evaluated. The fatigue life corresponding to different velocity of train ranging from 30 kmph to 140 kmph is generated similarly and compared to find the influence of velocity of moving load on fatigue life of structure. © Published under licence by IOP Publishing Ltd.",,,,,,,,,,,,,,,,,,"Ajmal, P C, Mohammed, A, Finite element analysis-based fatigue life evaluation approach for railway bridges: a study in Indian scenario (2018) Structural Monitoring and Maintenance, 5, pp. 429-443; Alavala, C R, (2008) Finite Element Methods: Basic Concepts and Applications, , (New Delhi, India: PHI Learning Pvt.

The cofferdams protected the area of the excavation pit mainly against the effects of flowing water. The paper includes analysis of the cofferdam for the foundation of the main central pillar of the asymmetrical bridge. The cofferdam has the ground plan dimensions of 44 x 20 m. It’s constructed of the double-row sheet pile walls. The stability of the cofferdam was analysed using numerical modelling based on the finite element method using Plaxis geotechnical software. The level of backfilling inside the cofferdam, required for construction of the foundations, was 6 m above the bottom of the river. The depth of the excavation pit of the cofferdam was about 4 m below the river bottom. The numerical model included 15 construction phases, which corresponded to the procedure of the construction. The analysis were focused mainly on construction phases, such as, e.g., the total backfill of the cofferdam, the loading from the piling rig, creating the excavation pit inside the cofferdam and installation of struts, and the load from the maximum level of the Danube River. The analysis showed that there are two critical phases. The first critical phase represents the situation when the piling rig works near the edge of the cofferdam, and the Danube River is at a minimal level. The second critical phase occurs when the full excavation pit created, and the Danube River is at a maximum level. © 2020 Institute of Physics Publishing.

From the perspective of improving the accuracy of composite damage detection, this paper proposes a scanning four-electrode electrical impedance nondestructive test method based on five different electrode radius measurement modes. The finite element analysis software COMSOL is used to construct an anisotropic CFRP laminate model, and the five measurement modes are compared and evaluated from the perspective of measurement accuracy, and three different types of structural damage are simulated to compare and analyze the detection results. In order to verify the validity of the model, by scanning the detection model, the structure damage information is obtained for image reconstruction, and a model suitable for CFRP damage detection is obtained. The research results show that the 0.7mm electrode radius measurement mode is better when detecting scratch damage; the 1.3mm electrode radius measurement mode is better when detecting impact and delamination damage. This research improves the measurement electrode structure, improves the detection accuracy of composite material non-destructive testing, and provides a reliable technical foundation for aircraft maintenance personnel. © 2020 IEEE.","carbon fiber composite; four-electrode; Measurement mode; non-destructive testing","Aircraft; Bridge decks; Carbon fiber reinforced plastics; Carbon fibers; Damage detection; Image reconstruction; Nondestructive examination; Structural health monitoring; Structural optimization; Carbon fibre composites; Composites damages; Electrical impedance; Electrode radii; Four-electrode; Measurement modes; Radius measurements; Real- time; Safe operation; Structure optimization; Electrodes",,,,,,,,,,,,,,,,"Xing, L., Jiang, S., Zhou, Z., Advances in manufacturing technology of advanced resin matrix composites[J] (2013) Journal of Composite Materials, 30 (2), pp. 1-9; Shaojie, C., Composite material technology and large aircraft[J] (2008) Acta Aeronautica Sinica, (3), pp. 605-610; Daijun, L., Yali, C., The application of advanced resin-based composite materials in the aviation industry [J] (2008) Materials Engineering, (Zl), pp. 194-198; Feng, S., BMW i3 pure electric vehicle-full carbon fiber composite body[J] (2012) Fiber Composite Materials, (3), p. 19; Shanyi, D., Advanced composite materials and aerospace[J] (2007) Journal of Composite Materials, (1), pp. 1-12; Ning, Z., Liu, R., Liu, H., Micro-modeling of thermal resistance change of fiber-containing fractured composites[J] (2017) Journalof Composite Materials, 34 (1), pp. 112-120; Minghui, L., Jundong, W., Yiping, Z., Peirui, L., Xuesong, Z., Shanpu, Z., Shuling, J., Ultrasonic characterization and analysis of macroscopic defects in rtm carbon fiber composites[J] (2017) FRP/Composite Materials, (4), pp. 70-74; Songping, L., Feifei, L., Enming, G., Ultrasonic imaging technology of interlayer defects in carbon fiber reinforced composites[J] (2009) Nondestructive Testing, (11), pp. 868-872",,"Li S.Dai Y.Ma J.Cheng Y.","et al.;Hunan University;Hunan University of Humanities, Science and Technology;Swinburne University of Technology;Wayne State University;Xiamen University","Institute of Electrical and Electronics Engineers Inc.","7th International Conference on Information Science and Control Engineering, ICISCE 2020","18 December 2020 through 20 December 2020",,171872,,9781728164069,,,"English","Proc. - Int.

As a perfect combination of beam bridges and arch bridges, the long-span deck-type BACRF bridge boasts a light structure, a strong bearing capacity, and a powerful spanning capability. From the perspective of mechanical system evolution, this paper theoretically analyzes the structural mechanics of the beam-arch composite system, establishes a half-bridge model for BACRF bridge, and derives the expressions of the internal force and displacement of the beam-arch composite system. Next, finite-element analysis was conducted to analyze how the variation of a single parameter, e.g., rise-span ratio, open web ratio, and side-to-middle span ratio, affects midspan displacement, arch-beam junction displacement, main beam bending moment, and main arch axial force.

To facilitate the interval arithmetic operation, two different strategies are proposed in this paper to transform the response-surface function into a corresponding interval response-surface function. These strategies minimize the inherent interval overestimation that can arise from the variable dependency of the surrogate model. In the first strategy, the natural extension and centered-form extension methods are used to mitigate the interval overestimation of the surrogate model, which may or may not contain interaction terms. In the second strategy, the natural extensión method is also adopted to realize the interval transformation of the surrogate model containing interaction terms but an affine arithmetic is further introduced to minimize the interval overestimation. To demonstrate the efficacy of the proposed method, model parameters are determined from an instrumented model of a cable-stayed bridge tested on a shaking table. Results show that the proposed updating method is feasible and effective for applications to finite element models of complex bridge structures. © 2020 World Scientific Publishing Company.","Finite element model updating; genetic algorithm; interval analysis; interval overestimation mitigation strategies","Cable stayed bridges; Surface properties; Uncertainty analysis; Affine arithmetic; Bridge structures; Extension methods; Interval arithmetic; Natural extension; Response surface functions; Structural parameter; Variable dependencies; Finite element method",,,,,"2016YFC0802202; National Science Foundation, NSF: 51678489, 51978577; Sichuan Province Science and Technology Support Program: 2016JY0130; Yunnan Provincial Science and Technology Department: SCMQ-201728-ZB; National Key Research and Development Program of China, NKRDPC","2016YFC0802202, National Science Foundation with 51678489&51978577, Sichuan Science and Technology Program with 2016JY0130, Science and Technology Program of Yunnan Provincial Communication Department with 2017(A)03, Science and Technology Project of Power China with SCMQ-201728-ZB.","The research reported in this paper was conducted as part of a series of research projects funded by the National Key Research and Development Plan with","The research reported in this paper was conducted as part of a series of research projects funded by the National Key Research and Development Plan with 2016YFC0802202, National Science Foundation with 51678489&51978577, Sichuan Science and Technology Program with 2016JY0130, Science and Technology Program of Yunnan Provincial Communication Department with 2017(A)03, Science and Technology Project of Power China with SCMQ-201728-ZB.",,,,,,,,"Çatbaş, F.

Nonetheless, losing soft-switching at high frequencies results in severe efficiency degradations along with excessive thermal and electrical stresses on the transistors. In a previous work, we have presented an enhanced-DAB (E-DAB) topology along with an adjustable-tap high-frequency transformer to extend soft switching over wider voltage gains. The E-DAB achieved a peak efficiency of 97.4% without any complex modulation techniques, enabling a power density of 10 kW/l (or 164 W/inch3) at 300 kHz. Here, we compare two different transformer geometries for their leakage inductance, quality factor and compatibility with the E-DAB. A theoretical gain-versus-power soft-switching characteristic for the E-DAB is verified by measurements of switching transients and amplitude spectrum analysis. The magnetic flux density and its distribution in the transformer core is analyzed using a finite-element analysis (FEA) method and the on-load operation of electromagnetic tap changers is presented. E-DAB converters are of great importance to renewable energy harvesting, Li-ion battery chargers, future dc distribution systems and smart grids due to their high efficiency, high power density and superior controllability. © 2020 IEEE.","DAB; electromagnetic relays; enhanced-DAB; GaN; matrix transformer; planar transformer; quality factor; soft switching; step up; tap changer; wide gain range","Electric power transmission networks; Energy harvesting; High frequency transformers; Lithium-ion batteries; Motion control; Power control; Power converters; Power electronics; Smart power grids; Spectrum analysis; Switching; Comprehensive designs; DC distribution system; Dual active bridges; Efficiency degradation; Leakage inductance; Li-ion battery chargers; Magnetic components; Switching transient; Electric power system control",,,,,,,,,,,,,,,,"Xue, L., Shen, Z., Boroyevich, D., Mattavelli, P., Diaz, D., Dual active bridge-based battery charger for plug-in hybrid electric vehicle with charging current containing low frequency ripple (2015) IEEE Trans.

However, the maximum switching frequency is limited by the transistor switching losses for both hard-switched and soft-switched converter topologies. To reduce the switching energy dissipation a half bridge design with low power loop inductance is required. This paper now presents an unequaled verification method that precisely determines the power loop inductance for PCB-based half-bridge circuits employing industry standard high-current transistor packaging. In such PCB designs, the minimization of power loop inductance is largely constrained by thermal vias required for enhanced heat dissipation. By detailed modeling of the transistor packaging and assembly technology maximum result convergence is achieved between Finite Element Analysis and a dedicated measurement environment. The high level of accuracy is finally used to predict the influenceof key design parameters on the power loop inductance value to conclude essential design guidelines. © 2020 IEEE.",,"Energy dissipation; Inductance; Organic pollutants; Polychlorinated biphenyls; Power converters; Switching; Timing circuits; Half-bridge; High currents; High-power-density; Loop inductance; PCB-based; Power; Power electronics converters; Soft-switched converters; Switching loss; Transistor switching; Bridge circuits",,,,,,,,,,,,,,,,"Ahmed, M.H., Fei, C., Lee, F.C., Li, Q., 48-V voltage regulator module with pcb winding matrix transformer for future data centers (2017) IEEE Transactions on Industrial Electronics, 64 (12), pp. 9302-9310. , Dec; Reusch, D., Biswas, S., Zhang, Y., System optimization of a high power density non-isolated intermediate bus converter for 48 v server applications (2019) IEEE Transactions on Industry Applications, 55 (2), pp. 1619-1627. , March; Su, G., Comparison of si, sic, and gan based isolation converters for onboard charger applications (2018) 2018 IEEE Energy Conversion Congress and Exposition (ECCE), pp. 1233-1239. , Sep; Zhang, W., Wang, F., Costinett, D.J., Tolbert, L.M., Blalock, B.J., Investigation of gallium nitride devices in high-frequency llc resonant converters (2017) IEEE Transactions on Power Electronics, 32 (1), pp. 571-583. , Jan; Kruse, K., Elbo, M., Zhang, Z., Gan-based high efficiency bidirectional dc-dc converter with 10 mhz switching frequency (2017) 2017 IEEE Applied Power Electronics Conference and Exposition (APEC), pp. 273-278. , March; Reusch, D., Strydom, J., Understanding the effect of pcb layout on circuit performance in a high-frequency gallium-nitride-based point of load converter (2014) IEEE Transactions on Power Electronics, 29 (4), pp. 2008-2015. , April; Krismer, F., Kolar, J., Accurate power loss model derivation of a high-current dual active bridge converter for an automotive application (2010) IEEE Transactions on Industrial Electronics, 57 (3), pp. 881-891. , March; Winter, C., Riedel, J., Mohzani, Z., Mencher, R., Butzmann, S., Enhancing inherent flux balancing in a dual-active bridge using adaptive modulation (2019) 2019 IEEE Applied Power Electronics Conference and Exposition (APEC), pp. 2202-2209. , March; Ibuchi, T., Funaki, T., A study on parasitic inductance reduction design in gan-based power converter for high-frequency switching operation (2017) 2017 International Symposium on Electromagnetic Compatibility-EMC EUROPE, pp. 1-5. , Sep; Zhang, X., Haryani, N., Shen, Z., Burgos, R., Boroyevich, D., Ultralow inductance phase leg design for gan-based three-phase motor drive systems (2015) 2015 IEEE 3rd Workshop on Wide Bandgap Power Devices and Applications (WiPDA), pp. 119-124. , Nov; Peng, H., Ramabhadran, R., Thomas, R., Schutten, M.J., Comprehensive switching behavior characterization of high speed gallium nitride e-hemt with ultra-low loop inductance (2017) 2017 IEEE 5th Workshop on Wide Bandgap Power Devices and Applications (WiPDA), pp. 116-121. , Oct; Letellier, A., Dubois, M.R., Trovao, J.P.F., Maher, H., Calculation of printed circuit board power-loop stray inductance in gan or high di/dt applications (2019) IEEE Transactions on Power Electronics, 34 (1), pp. 612-623. , Jan; Sun, B., Jorgensen, K.L., Zhang, Z., E.ersen, M.A., Multiphysic analysis for gan transistor pcb layout (2019) 2019 IEEE Applied Power Electronics Conference and Exposition (APEC), pp. 3407-3413. , March; Mechanical Case Outline hpsof8l, , https://www.onsemi.com/pub/Collateral/100CU.PDF, ON Semiconductor.

The dynamic behaviour is represented by the natural frequencies and damping which are subsequently used along with the considered dynamic actions in the design process. In regard of integral bridge concept, one of the consequences of the omission of joints and bearings is the substantial soil-structure interaction which in turn increases the sensitivity of the dynamic behaviour of the bridges to the surrounding soil characteristic. In this article, we extended our hybrid BEM-FEM steady-state dynamic numerical tool to the 3D regime, developed by utilizing an in-house BEM and the commercial FEM software ABAQUS and use it to analyse the dynamic interaction between the bridge and the underlying soil as well as the backfill. The numerical results from four typical integral bridges show that underlying soil characteristic has great effect on the resonant frequencies and the damping. The backfill material properties tend to have less significant role due to the abutment wingwalls dominating the force transfer between the soil and the superstructure. The results also show that the degree of influence of the soil-structure interaction on the coupled system is affected by the type of load pattern in addition to the flexural stiffness of the superstructure. © 2020, VDI Fachmedien GmBbH & Co..

Some concrete members fell into the river, causing significant changes in the structural behaviour of the bridge. Thereafter, the administration department has done some emergency detection, strengthening design and strengthening construction to the bridge. A field load test and simulation of the bridge using the large-scale general finite-element analysis software Midas were performed. According to the comparative analysis and model validation of the field load test and the results of simulation analysis, the bridge bearing capacity after strengthening is evaluated, and a maintenance proposal for the bridge is given. The results of the research show that the results of static and dynamic load tests agree well with the theoretical value; the latter verifies the correctness of the theoretical analysis. Based on the field load test, comparative analysis and computational evaluation, the strengthening effect on the WanJiang Bridge is evaluated from the aspects of static performance and dynamic performance. © 2021 ICE Publishing: All rights reserved.",,"Bridge piers;

To meet these requirements, the design of island-bridge structure is adopted, so that the sensor network can be manufactured in a limited scale and expanded in a large scale. Theoretical analysis, finite element simulation and experimental verification have been carried out on the mechanical properties of island-bridge structures. However, theoretical analysis is difficult to analyze irregular shaped structures, and the existing simulation researches mainly focus on the island-bridge structures with one unit and lack the analysis of networks. In this work, the finite element simulation method of island-bridge structure networks based on ABAQUS has been proposed, which includes buckling mode analysis and postbuckling deformation analysis. The initial buckling deformation state of the structure is extracted by the buckling mode analysis, and the postbuckling deformation state of the structure can be obtained by the postbuckling deformation analysis. The simulation method is applied on the analysis of the mechanical properties and deformation patterns of different island-bridge structure networks, including serpentine, fractal and irregular island-bridge structure networks. This shows that the proposed simulation method can well guide the design of stretchable sensor networks. © 2020 IEEE.","aircraft smart skin; flexible and stretchable; island-bridge structure; sensor network; simulation method; structural health monitoring","ABAQUS; Aircraft; Aircraft manufacture; Airframes; Artificial intelligence; Buckling; Deformation; Mechanical properties; Sensor networks; Serpentine; Aircraft structure; Buckling and post-buckling; Deformation pattern; Finite element simulations; Lightweight sensors; Post buckling deformation; Shaped structures; Simulation research; Finite element method",,,,,"2018ZA52010; National Natural Science Foundation of China, NSFC: 51635007, 51921003, 51975292; Priority Academic Program Development of Jiangsu Higher Education Institutions, PAPD","ACKNOWLEDGMENT This work was supported by the National Natural Science Foundation of China (Grant No. 51635007, 51975292, and 51921003), the Aviation Foundation of China (Grant No. 2018ZA52010) and the Priority Academic Program Development of Jiangsu Higher Education Institutions.",,,,,,,,,,"Foote, P.D., Integration of structural health monitoring sensors with aerospace, composite materials and structures (2015) Mat.-wiss.

With regards to wind energy applications, the Outer-Rotor Flux-Modulated Permanent Magnet (OR-FMPM) generator with a spoke-type magnet arrangement offers improved torque capability and has emerged as a promising topology for direct-drive systems. However, the 'flux-barrier' effect associated with this configuration significantly increases the harmonic leakage flux and can effectively offset the improvement in torque capability. This paper presents a detailed comparative analysis of a conventional FMPM machine topology and the so-called improved topology - which has a flux bridge added to the outer-rotor to mitigate the flux barrier effect. Detailed Finite Element Analyses presented in this paper highlight how the addition of a suitably-sized flux-bridge can yield 120% higher effective airgap magnetic loading, and hence improved torque capability, albeit with a detrimental effect on the power factor characteristics. Consequently, this paper highlights the inherent trade-off between torque density and power factor of these FMPM machines. The paper also provides guidance on the sizing of the flux bridge as well as practical considerations for power factor improvement. © 2020 IEEE.","Flux-bridge; Flux-Modulation; Generator; Outer-rotor; Permanent Magnet; Spoke-array","Economic and social effects; Electric power factor; Energy conversion; Investments; Permanent magnets; Synchronous generators; Topology; Torque; Wind power; Comparative analysis; Direct-drive system; Energy applications; Magnetic loading; Permanent magnet generator; Power factor improvement; Renewable energy technologies; Torque capability; Electric generators",,,,,,"This work was supported in part by the South African government through the Department of Science and Technology and in part by the National Research Foundation.",,,,,,,,,,"Ishizaki, A., Tanaka, T., Takasaki, K., Nishikata, S., Theory and optimum design of pm vernier motor (1995) 1995 Seventh International Conference on Electrical Machines and Drives (Conf.

Presently, the system is generally adopted for newly constructed bridges and the seismic retrofitting of existing bridges. Cable type bridge restrainers are included in the system, and they are expected to prevent superstructures from exceeding the seat length of substructures. Although the bridge restrainer works during an earthquake, it is designed to be static in the current design. In addition, although the constituent elements of bridge restrainers include a rubber cushion to absorb energy during an earthquake, the effect is not included in the design. Thus, the current design lacks the dynamic effects of earthquakes and the cushioning effect of the rubber. Furthermore, in the case of a multi-span bridge, there is no particular decision as to where the restrainers should be placed or what kind of specifications they should have. Therefore, in this paper, a new design concept that considers the dynamic action of the earthquake and the cushioning effect of the rubber is proposed by coupling dynamic response analysis using a frame finite element (FE) model and a simple genetic algorithm (SGA). © 2020 by the authors.","Bridge restrainer; Cushion effect; Design concept; Dynamic finite element analysis; Optimization design; Simple genetic algorithm",,,,,,,,,,,,,,,,,"(1996) Specifications for Highway Bridges, 5; Specifications for Highway Bridges (2012), 5; Wright, T., DesRoches, R., Padgett, J.E., Bridge seismic retrofitting practices in the central and southeastern United States (2011) J.

The permanent magnets are disposed of in a way that increases the thrust force of a double-sided linear switched reluctance actuator of the same size. To achieve this objective, each phase of the actuator is powered by a single H-bridge inverter. To reduce the detent force, the upper and the lower stator were shifted. Finite element analysis was used to demonstrate that the proposed actuator has a high force density with low detent force. In addition, a comparative study between the proposed linear hybrid reluctance actuator, linear switched reluctance, and linear permanent magnet actuators of the same size was performed. Finally, experimental tests carried out in a prototype confirmed the goals of the proposed actuator. © 2020 by the authors","Detent force reduction; Finite element analysis; Linear electric actuators; Linear hybrid reluctance actuators; Linear switched reluctance actuators; Machine design; Permanent magnets","Actuators; Bridge circuits; Permanent magnets; Stators; Comparative studies; Experimental test; H-bridge inverters; High force density; Linear permanent magnet; Linear switched reluctance actuators; Reluctance actuator; Switched reluctance; Magnetic actuators",,,,,,,,,,,,,,,,"Amoros, J.G., Andrada, P., Sensitivity Analysis of Geometrical Parameters on a Double-Sided Linear Switched Reluctance Motor (2010) IEEE Trans.

The enhanced performance has been quantified through a number of material characterization studies and large-scale experimental research programs. Results from earlier studies conducted beginning in the late 1990s demonstrated the extreme potential of high-toughness materials for use in bridge applications. More recent studies have focused on identifying the toughness level required to potentially eliminate the concern of sudden brittle fracture in the presence of a small flaw in new structures fabricated with such materials. The research consisted of material characterization, full-scale fracture testing, three-dimensional finite-element analysis (FEA), and an analytical parametric study. From the work, the idea of an integrated fracture control plan (FCP) resulted. In an integrated FCP, the likelihood of brittle fracture is minimized through a series of interrelated components which interact in a rational and quantifiable manner. The current paper explores the results from large-scale experiments on axially loaded plates with reference to a separate material characterization study and large-scale flexure experimental results. Results of the study demonstrated fracture toughness demands calculated using FEA compared favorably with 1T single-edge bend [SE(B)] material characterization experiments and large-scale flexure experiments. © 2020 American Society of Civil Engineers.","Charpy V-notch; Fracture; Fracture critical; High-performance steel; Integrated fracture control plan; Toughness","Brittle fracture; Fracture testing; Bridge applications; Experimental research; Fracture experiments; Interrelated components; Large scale experiments; Material characterizations; Production techniques; Three dimensional finite element analysis; Fracture toughness",,,,,,,,,,,,,,,,"(2011) The Manual for Bridge Evaluation, , AASHTO.

Previous studies are mostly conducted by assuming that the bridge is under its own stability conditions, without considering the impact of construction error, changes of external condition and wind-induced vibration on the stability of the bridge, which poses serious challenges to the bridge construction process. This paper aims to analyze the extent to which static load and fluctuating wind effect influence structural stability and to test the credibility of the structure. Design/methodology/approach: A finite element calculation method is used to analyze a T-shaped rigid frame swivel bridge. A full bridge model was built, and a local model of the turntable structure established; the two are then combined means of node coupling. Subsequently, the three sensitivity indexes – deflection rate, stress change rate and the change rate of spherical hinges – are used to evaluate in what way the bridge stability is influenced under various factors. Findings: It is found that the stability of the swivel bridge is quite sensitive to unilateral overweight, steel beam tension and wind-induced vibration effects but less sensitive to the change of bulk density. Also found is that the change of elastic modulus exerts some effects on deflection but has negligible effects on other stability indexes. Furthermore, the transverse unbalanced torque on the bridge generated by wind-induced vibration is an important factor in determining the size of the turntable, indicating that it is not just controlled by the weight of the bridge. Originality/value: All factors affecting the stability of swivel construction are analyzed, and solutions to reduce the influence are proposed. The influence of wind-induced vibration effects on swivel construction is analyzed for the first time. It is pointed out that wind-induced vibration effects have great influence on the structure, and its influence could not be neglected. © 2020, Emerald Publishing Limited.","Finite element method; Numerical models; Sensitivity analysis; Swivel construction; Vibration analysis; Wind-induced vibration","Construction; Rigidity; Sensitivity analysis; Stability; Structural design; Vibration analysis; Wind effects; Bridge constructions; Construction method; Construction process; Design/methodology/approach; Parameter sensitivity analysis; Rigid-frame bridges; Structural stabilities; Wind induced vibrations; Bridges",,,,,"Fundamental Research Funds for the Central Universities: 2572017AB18","Supported by “the Fundamental Research Funds for the Central Universities”, The project number is 2572017AB18.",,,,,,,,,,"Che, X., Zhang, X., Overturning resistance of large tonnage T-shaped rigid frame bridge during turning (2014) Journal of China Highway, 27 (8), pp. 66-72; Davenport, A.G., Buffeting of a suspension bridge by storm winds (1962) Journal of Structural Division, ASCE, 88 (ST3), pp. 233-268; Du, J., Innovation and prospect of bridge rotation construction technology (2012) Journal of Railway Construction Technology, (4), pp. 7-11; Gao, R., Hu, Z., Gaotao, M., Analysis of influence of train-induced vibration on the stability of swivel construction bridge (2014) Railway construction, (5), pp. 16-18; Gharpure, D.R., Biyani, S.R., Poira bridge: construction of India's first horizontal swing bridge (2007) Indian Concrete Journal, 81, pp. 33-35; Gu, M., Chen, S., Practical method for aerodynamic coupling buffeting response analysis of long-span bridge (2004) China Civil Engineering Journal, (2), pp. 33-37+110; Huang, W., (2014) Study on Wind Resistance Performance of T-Shaped Rigid Frame Bridge in Swivel Construction, , Wuhan University of Technology, Wuhan; Lu, J., (2016) Research on Construction Control and Stability of Large Tonnage Continuous Rigid Frame Bridge, , Lanzhou Jiaotong University, Lan Zhou; Ma, S., (2014) Sensitivity Analysis of T-Frame Bridge Parameters for Large-Span Swivel Construction, , Wuhan University of Technology, Wuhan; Pang, L., (2015) 140m+240m+140m Research on Construction Monitoring Technology of Single Cable Plane Rotary Cable-stayed Bridge, , Shijiazhuang Railway University, Shijiazhuang; Sheng, L., (2006) Study on Structural Stability of Open Thin-Walled Box Arch Bridge during Swivel Construction, , Wuhan University of Technology, Wuhan; Siwowski, T., Wysocki, A., Horizontal rotation via floatation as an accelerated bridge construction for long-span footbridge erection: case study (2015) Journal of Bridge Engineering, 20, pp. 124-126; (2018) Specifications for Design of Highway Reinforced Concrete and Prestressed Concrete Bridges and Culverts, , China Architecture & Building Press, JTG 3362-2018; Sun, Y., Force analysis of characteristic components of rotary bridge (2013) Journal of Liaoning Communications College, 15 (2), pp. 4-7. , 11; Wang, L., Yuan, C., Sun, Y., Sensitivity analysis of parameters in construction control of swivel cable-stayed bridge (2007) Journal of Northeast Forestry University, (6), pp. 42-43+62; Wang, L., Wang, E., Sun, Y., Mechanical characteristics of 10,000-ton cable-stayed bridge during Swivel Construction (2015) Journal of Transportation Engineering, 15 (3), pp. 52-61; Watanabe, E., Maruyama, T., Tanaka, H., Takeda, S., Design and construction of a floating swing bridge in Osaka (2000) Marine Structures, 13, pp. 437-445; Yuan, B., Ying, H., Xu, J., Simulation of fluctuating wind speed based on linear filtering method and implementation of MATLAB program (2007) Structural Engineers, (4), pp. 55-61; Yuan, B., Zeng, M., Li, X., Computer simulation of fluctuating wind based on FFT technology and implementation of Matlab (2013) Sichuan Building Science, 39 (5), pp. 29-32+42; Zhai, P., (2008) The Problem of Unbalance and Wind-Induced Vibration in Swivel Construction, , Beijing Jiaotong University, Beijing; Zhai, J., (2018) Study on the Influence of Wind-Induced Effects on the Swivel Construction of T-Bridges, , Chongqing Jiaotong University, Chongqing; Zhang, L., (2011) Influence of Train-Induced Vibration on Stability of Large Cantilever Beam, , Beijing Jiaotong University, Beijing; Zhang, J., El-Diraby, T.E., Constructability analysis of the bridge superstructure rotation construction method in China (2006) Journal of Civil Engineering and Management, 132, pp. 353-360; Zhang, J., Zhong, Q., Achievements and development of bridge horizontal rotation construction (1992) Journal of Railway Standard Design, (6), pp. 19-28; Sun, Y., (2007) Study on the Stress of the Horizontal Rotation Stage of the Cable-Stayed Bridge over Suifen River, , Northeast Forestry University, Harbin","sun, Q.; Northeast Forestry UniversityChina; email: hrbsqs@126.com",,,"Emerald Group Holdings Ltd.",,,,,15736105,,,,"English","Multidiscip.

Equations of motion for the train-bridge interaction system were derived, where the track-wheel interaction was described by the Coulomb friction law. A full train-bridge finite element model incorporating nonslip and stick-slip interaction models was built using commercial finite element analysis software: Abaqus. Simulation results indicate that the slip phenomenon might occur under a moderate earthquake and that a conventional nonslip model with an infinitely large friction coefficient is inappropriate. A parametric study revealed that the braking-Train-induced slip friction little influenced the bridge response to moderate earthquake forces. The bridge's dynamic motions were dominated by ground motion irrespective of the values assigned as the train's initial speed and track-wheel friction coefficient. A computationally efficient method was proposed for calculating the longitudinal seismic responses of a bridge interacting with a braking train, following the linear superposition principle. As illustrated, this method could be helpful in reliability or uncertainty analysis when a great number of computationally expensive seismic analyses are required for train-bridge interaction systems. © 2020 American Society of Mechanical Engineers (ASME).

The temperature distribution model was incorporated into a simplified rut-depth prediction equation and a finite-element analysis (FEA) model. The prediction results based on the two methods were compared with the testing results. First, a generalized extreme value distribution function was chosen to describe the probability distribution of the pavement temperatures. With properly selected fitting parameters, it was found that the generalized extreme value distribution function fit the monitoring temperature data well. Then, an empirical rut-depth prediction formula was adopted considering effects of asphalt dynamic modulus, dynamic stability, temperature influence, vehicle speed and location, and annual average daily traffic. Thanks to the development of the pavement temperature distribution model, the sum of time duration for temperature above 40°C could be calculated and the temperature coefficient in the simplified rutting prediction equation could be obtained. On the other hand, the temperature duration was also incorporated into the three-dimensional (3D) FEA model based on the modified Burger's model, accounting for pavement's viscoelasticity, to make the rutting evaluation using FEA possible. It indicated that the simplified rutting prediction yielded a better result than the comprehensive FEA result, which suggests a fast and simple method for local practical engineers. It was suggested that more efforts be made to improve the accuracy of the FEA method in the future. © 2020 American Society of Civil Engineers.",,"Asphalt; Distribution functions; Forecasting; Monitoring; Steel bridges; Temperature distribution; Annual average daily traffics; Continuous monitoring; Finite element analysis modeling; Generalized extreme value distribution; Nanjing Yangtze river bridge; Temperature coefficient; Temperature monitoring; Threedimensional (3-d); Box girder bridges; asphalt; bridge; monitoring; pavement; prediction; temperature effect; viscoelasticity; China; Jiangsu; Nanjing [Jiangsu]; Yangtze River",,,,,"2014H27; National Natural Science Foundation of China, NSFC: 51108152","The authors are grateful for the joint support of the National Natural Science Foundation of China (No. 51108152), and the Project of Science Research Program Transportation Department of Zhejiang Province of China (2014H27).",,,,,,,,,,"Ameri-Gaznon, M., (1989) Permanent deformation potential in asphalt concrete overlays over portland cement concrete pavements, , Ph.D. thesis, Texas Transportation Institute, Texas A&M Univ; Arockiasamy, M., Reddy, D.V., Sivakumar, M., Fatigue loading and temperature distribution in single cell segmental box bridges (2008) Pract.

The construction of the columns to support the bridge at an alternate position caused the modification in span lengths was chosen to study in this research. This method must be also achieved with the least impact of traffic. The threespan prestressed concrete bridge was simulated and analyzed by the finite element method. The models were subjected to the vehicles according to the standard loadings of Thai truck loads. The moving loads were applied to the bridge models which have the existing spans and varied spans caused by the construction of replaced columns. The variations in bridge lengths were ranged from 5% to 25% with an interval of 5% and caused the shortening of the first span and lengthening of the middle span. The bridge lengths were varied from 26.25 to 43.75 meters respectively. The stress analyses were carried out to determine the stresses induced in concrete, tendons, and rebars and then compared to their allowable strength. The conclusions were made for the span lengths which could affect the serviceability of the bridge. © 2020 River Publishers.

In the same manner, structures subjected to vehicle impact load, such as bridge columns, could potentially take advantages of the P-I diagram if the dynamic characteristics of vehicle impact load and bridge columns are well considered. In the paper, the performance of bridge columns and hence the use of P-I diagram is evaluated under vehicle impact load. The main tasks of the paper are (1) to determine the dynamic characteristics of vehicle impact load through finite element method, and three simplified load shapes are obtained including isosceles triangle, right triangle, and rectangular shapes; (2) to investigate structural failure modes under various shear-bending ratios and impact loads; (3) to establish the damage index based on the residual axial capacity of bridge columns and to obtain P-I diagrams at different damage levels of bridge columns under vehicle impact load; (4) to parametrically analyze the effects on the impulse asymptotic and the peak load asymptotic of P-I diagrams, including column diameter, stirrup reinforcement ratio, longitudinal reinforcement ratio, and strength of the concrete. Finally, a simplified calculation method of P-I diagrams is proposed to evaluate the performance of bridge columns under vehicle impact load. © 2020 fib.

The Rivière-aux-Mulets bridge was one of them. Built in the early 1960s, this bridge experienced several disorders due to inadequate design criteria enforced at that time. Despite a structural strengthening in the late 1980s, a bridge behavior follow-up has been required to ensure reliability. The structural health monitoring program implemented to track structural disorders, along with results from modal analysis and diagnostic load tests, is presented with a focus on the instrumentation and the data analysis. A three-dimensional finite element model was developed and calibrated using the frequencies and mode shapes detected under ambient traffic conditions. Data analyses showed that the expansion bearings were frozen, causing bending of the associated piers, which generated axial forces in the deck and decompression of concrete in the area surrounding active cracks. This process enables premature failure of prestressing tendons in the vicinity of these cracks, especially those located in the top flange, which is a corrosion-friendly environment. Development of cracks and associated prestress loss caused a reduction in the bridge load-carrying capacity. Analyses of health monitoring data led to acute assessment of the overall bridge structural performance. © 2020 American Concrete Institute.

One particular ABC technology is the use of precast concrete members joined with mechanical connectors. However, there are concerns about these connections in moderate-to-high seismic regions. A study was carried out for the Idaho Transportation Department (ITD) on the seismic performance of precast columns with grouted couplers versus the conventional cast-in-place columns. Experimental data provided the necessary input to model the grouted couplers. Using the OpenSees finite element analysis program, selected bridges were subjected to the seismic conditions of the most seismically active location in Idaho. Under seismic conditions considered, the stresses in both the longitudinal reinforcing bars and the grouted coupler regions are found to be well within acceptable ranges. The study resulted in recommendations on allowable column drifts, a list of approved grouted rebar couplers, and typical detail drawings for inclusion in the ITD's Bridge Manual. © 2020 American Concrete Institute.

Bridge structures typically incorporate deep concrete elements, such as cap beams or bent caps, with higher shear strengths than slender elements. However, many in-service bridges did not account for the deep beam effects in their original design due to the lack of suitable analysis methods at that time. Nonlinear finite element analysis (NLFEA) can provide a better assessment of the load capacity of deep bridge bent beams while accounting for the deep beam action. However, there is little guidance on how to conduct a numerical strength evaluation using the NLFEA. This study presents a nonlinear modeling methodology for the strength evaluation of deep bridge bents while considering advanced concrete behavior such as tension stiffening, compression softening, and dowel action. Five existing bridge bent beams are examined using the proposed methodology. The effectiveness and advantages of the proposed methodology are discussed by comparing the numerical results, including the load-displacement responses, load capacities, cracking patterns and failure modes, with the strut-and-tie and sectional analysis methods. Important modeling considerations are also discussed to assist practitioners in accurately evaluating deep bridge bents. © 2020 American Concrete Institute.

It contains 50 concrete spans. The 10 ft (3.1 m) deep I-girders span 172 ft (52.4 m) and are post-tensioned. Because the prestressing steel has suffered from corrosion, it was necessary to use advanced techniques to evaluate the performance of these I-girders. Detailed twodimensional non-linear finite element modelling was used to determine the responses at service load and at ultimate. Three-dimensional finite element modelling was carried out to determine the loading for the two-dimensional modelling. The serviceability checks examined if cracking would occur and the strength requirements were evaluated using predicted demand-to-capacity ratios (D/C). These analysis tools also enabled the influence of a number of strengthening techniques to be assessed. The influence of different strengthening techniques on the predicted responses of the diaphragms was also studied. The combinations of strengthening measures were found to be effective in achieving the desired serviceability and strength requirements. © 2020 American Concrete Institute.

A large experimental program was carried out to test three decommissioned solid slab bridges to failure. In parallel, an extensive nonlinear finite element analysis study was performed with the aim of better understanding the failure mechanisms, the degree of load redistribution, and to gain insight into the ultimate shear capacity of these structures. A beam shear failure mode was expected for the first two bridge tests, but a flexural failure mode was observed. This paper focusses mainly on the last field test of a simply supported solid slab bridge having a 40 degree skew. The load position and the loading protocol were established with the objective of causing a shear failure at the obtuse corner of the slab where high shear forces develop. The main test motivation was to illustrate that simply supported solid slab bridges would normally not be prone to shear failure due to an intrinsic redundancy. The paper presents experimental techniques that could help bridge owners in assessing the performance of their bridges. The test results also provide valuable information for calibrating nonlinear element models that can be used for assessing the carrying capacity of existing concrete bridges. Although the actual bridge conditions were worse than anticipated, a global shear failure mode occurred near the obtuse corner at a maximum load of 1400 kN, which significantly exceeded the factored shear force due to the maximum traffic load. The failure was followed by a gradual load redistribution toward undamaged portions of the slab. This field test confirmed the assumption of non-fragility for this type of bridge, where support conditions enable development of an intrinsic redundancy. Despite these observations, nonlinear analyses carried out in parallel to the testing program indicated that this beneficial effect diminishes with an increase of slab thickness. © 2020 American Concrete Institute.

A total of 96 bridge cases were modeled using finite-element analysis (FEA) and bridge parameters such as span length, slab width, and skew angle are varied within practical ranges. Typical railings built integrally with the bridge were placed on both edges of the deck slabs. AASHTO HS20 truck loadings were positioned transversely and longitudinally to produce maximum longitudinal live load bending moments in the slabs. The FEA wheel load distribution and bending moments were compared with reference straight bridges without railings as well as to the AASHTO Standard Specifications for Highway Bridges and the AASHTO LRFD Bridge Design Specifications. AASHTO overestimates FEA moments for almost all bridge cases and this overestimation increases with the increase in the skew angle, and it is more significant in the presence of two railings. Also, it was found that the reduction in slab moment due to skewness and railings is cumulative. The presence of railings can be considered to be a possible method for strengthening and rehabilitating straight and skewed concrete slab bridges. © 2020, Int.

Cross-frames are also generally assumed to have important roles in live-load distribution. This work evaluates a novel means for considering the overall stress distribution throughout finite element models, in contrast to other contemporary methods that quantitatively analyze only isolated stresses. This method is used to evaluate different cross-frame designs, including the absence of cross-frames, for simply-supported composite skewed steel I-girder bridges. Considering all results, from both newly proposed and conventional metrics, it is demonstrated that the influence of cross-frame design often has a more significant influence than the presence or absence of cross-frames. Thus, the importance of cross-frames may be less than previously thought. Furthermore, the data reveals that the greatest differences between models were generally due to the use of staggered cross-frames, which also cause the most significant departures from traditional expectations of girder behavior. © 2020 Elsevier Ltd","Cross-frames; Data analysis; Finite element analysis; I-girder bridges; Steel bridges; Stress","Data reduction; Design; Finite element method; Stiffness; Stress concentration; Stresses; Cross-frames; I-girders; Live loads; Simply supported; Steel I-girder bridges; Steel bridges; bridge; finite element method; holistic approach; quantitative analysis; steel structure; stress analysis; structural component",,,,,,,,,,,,,,,,"American Association of State Highway and Transportation Officials.

We approximate the structure of freeze-cast PZT parallel laminae joined by links (or bridges) by a model that can be broken down into two directions along which the structure resembles a laminate. The effective coefficients obtained in the first step of the recursion are then used as input on the second step which gives the final effective moduli. The comparison of those with calculations via Finite Element Method (FEM) on a non-recursive model shows good agreement. Finally, we calculate the piezoelectric and pyroelectric figures of merit and compare them with experimental results. The proposed scheme is a good alternative since it relies only on known simple analytical formulae and has a very low computational cost with respect to other methods that may be applied to such a geometry. © 2020 Walter de Gruyter GmbH, Berlin/Boston 2020.","figures of merit; homogenization; piezoelectricity; porous ceramics; pyroelectricity","Computational geometry; Crystallography; Piezoelectric devices; Piezoelectricity; Pyroelectricity; Analytical formulas; Broken down; Effective property; Figure of merit; Homogenization; Porous ceramics; PZT; Recursions; Simple schemes; Two directions; Energy harvesting",,,,,"Consejo Nacional de Ciencia y Tecnología, CONACYT","Research funding: Financial support to this work was granted by the project PAPIIT-DGAPA-UNAM IA100919 and CONACyT (ROC’s Ph.D. scholarship).",,,,,,,,,,"Belytschko, T., Liu, W.K., Moran, B., (2000) Nonlinear Finite Elements for Continua and Structures, , Chichester John Wiley & Sons; Berlincourt, D.A., Curran, D.R., Jaffe, H., Piezoelectric and Piezomagnetical Materials and Their Function in Transducers (1964) Physical Acoustics, pp. 169-270. , New York Academic Press; Bowen, C.R., Taylor, J., Le Boulbar, E., Zabeka, D., Topolov, V.Yu., A Modified Figure of Merit for Pyroelectric Energy Harvesting (2015) Journal of Mathematical Analysis and Applications, 138, pp. 243-246. , https://doi.org/10.1016/j.matlet.2014.10.004; Brenner, R., Bravo-Castillero, J., Mesejo-León, D., Investigation of the Effective Response of 2-1-2 Piezoelectric Composites (2012) Procedia Iutam, 3, pp. 292-300. , https://doi.org/10.1016/j.piutam.2012.03.018; Bravo-Castillero, J., Rodríguez-Ramos, R., Mechkour, H., Otero, J.A., Hernández-Cabanas, Y., Sixto, L.M., Guinovart-Díaz, R., Sabina, F.J., Homogenization and Effective Properties of Periodic Thermomagnetoelectroelastic Composites (2009) Journal of Mechanics of Materials and Structures, 4, pp. 819-836. , https://doi.org/10.2140/jomms.2009.4.819; Caballero-Pérez, R.O., Bravo-Castillero, J., Pérez-Fernández, L.D., Rodríguez-Ramos, R., Sabina, F.J., Homogenization of Thermo-Magneto-Electro-Elastic Multilaminated Composites with Imperfect Contact (2019) Mechanics Research Communications, 97, pp. 16-21. , https://doi.org/10.1016/j.mechrescom.2019.04.005; Deutz, D.B., Pascoe, J.A., Schelen, B., Van Der Zwaag, S., De Leeuwa, D.M., Groen, P., Analysis and Experimental Validation of the Figure of Merit for Piezoelectric Energy Harvesters (2018) Materials Horizons, 5, pp. 444-453. , https://doi.org/10.1039/c8mh00097b; Guinovart-Díaz, R., Rodríguez-Ramos, R., Bravo-Castillero, J., Sabina, F.J., Otero-Hernández, J.A., Maugin, G.A., A Recursive Asymptotic Homogenization Scheme for Multi-phase Fibrous Elastic Composites (2005) Mechanics of Materials, 37, pp. 1119-1131. , https://doi.org/10.1016/j.mechmat.2005.02.003; Newnham, R.E., Skinner, D.P., Cross, L.E., Connectivity and Piezoelectric-Pyroelectric Composites (1978) Materials Research Bulletin, 13, pp. 525-536. , https://doi.org/10.1016/0025-5408(78)90161-7; Otero, J.A., Bravo-Castillero, J., Guinovart-Díaz, R., Rodríguez-Ramos, R., Maugin, G.A., Analytical Expressions of Effective Constants for a Piezoelectric Composite Reinforced with Square Cross-Section Fibers (2003) Archives of Mechanics, 55, pp. 357-371; Roscow, J., Zhang, Y., Taylor, J., Bowen, C.R., Porous Ferroelectrics for Energy Harvesting Applications (2015) Epj St, 224, pp. 2949-2966. , https://doi.org/10.1140/epjst/e2015-02600-y; Sebald, G., Seveyrat, L., Guyomar, D., Lebrun, L., Guiffard, B., Pruvost, S., Electrocaloric and Pyroelectric Properties of 0.75Pb(Mg1/3Nb2/3)O3 - 0.25PbTiO3 Single Crystals (2006) Journal of Applied Physics, 100, p. 124112. , https://doi.org/10.1063/1.2407271; Sebald, G., Lefeuvre, E., Guyomar, D., Pyroelectric Energy Conversion: Optimization Principles (2008) Ieee Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 55, pp. 538-551. , https://doi.org/10.1109/tuffc.2008.680; Sixto-Camacho, L.M., Bravo-Castillero, J., Brenner, R., Guinovart-Díaz, R., Mechkour, H., Rodríguez-Ramos, R., Sabina, F.J., Asymptotic Homogenization of Periodic Thermo-Magneto-Electro-Elastic Heterogeneous Media (2013) Computers & Mathematics with Applications, 66, pp. 2056-2074. , https://doi.org/10.1016/j.camwa.2013.08.027; Topolov, V.Y., Bowen, C.R., Bisegna, P., Piezo-Active Composites.

FEA was used to calculate the stress distribution in implant bridges. The 200 N loading was applied to simulate occlusal function. The stress distribution occurred at the gingival surface above the interface in all the groups. The peak stress of IPIB was lower than SIB and EPIB. Further, two porous cylinders with external and internal pore structure were precisely fabricated to better understand its structural responses, stress distribution patterns and micromotions. Results showed that the peak stress and total deformation of internal porous cylinder was much lower than external porous cylinder. This study indicated that IPIB design maintained the better geometric characteristics and exhibited better stress distribution than EPIB design. © 2020 IEEE.","FEA; Internal and external porous implant bridge; Static mechanical performance; Stress distribution patterns","Cylinders (shapes); Electron devices; Finite element method; Pore structure; Stress concentration; Distribution patterns; Geometric characteristics; Mechanical performance; Micro motion; Porous cylinders; Porous implants; Porous structures; Structural response; Structural design",,,,,"Guangzhou Science and Technology Program key projects: 201906010032","Acknowledgements This research was financially supported by 1) the Science and Technology Program of Guangzhou (No. 201906010032); 2) New Dental Implant and Clinical Application Engineering Technology Research Center of Guangdong.",,,,,,,,,,"Drago, C., Howell, K., Concepts for designing and fabricating metal implant frameworks for hybrid implant prostheses (2012) Journal of Prosthodontics Official Journal of the American College of Prosthodontists, 21 (5); Marianella, S., Vivas, J.L., Razzoog, M.E., Rui-Feng, W., Precision of fit of titanium and cast implant frameworks using a new matching formula (2012) International Journal of Dentistry, pp. 1-9; Ortorp, A., Jemt, T.T., Tord, J., Comparisons of precision of fit between cast and cnc-milled titanium implant frameworks for the edentulous mandible (2003) International Journal of Prosthodontics, 16 (2), pp. 194-200; Miyazaki, T., Hotta, Y., CAD/CAM systems available for the fabrication of crown and bridge restorations (2011) Australian Dental Journal, 56, pp. 97-106; Piconi, C., Maccauro, G., Muratori, F., Alumina and zirconia ceramics in joint replacements (2013) J Appl Biomat Biomec, 1, pp. 19-32; Lautenschlager, E.P., Monaghan, P., Titanium and titanium alloys as dental materials (1993) Int Dent J, 43, pp. 245-253; Ishigaki, S., Nakano, T., Yamada, S., Nakamura, T., Takashima, F., Biomechanical stress in bone surrounding an implant under simulated chewing (2003) Clin Oral Impl Res, 14, pp. 97-102; Natali, A.N., Pavan, P.G., (2003) Numerical Approach to Dental Biomechanics.

Such gaps can form because of different reasons, including settlement of soft soil, unsuitable construction of a concrete slab on loosely compacted soil, and drastic stiffness change in a transition zone between the bridge deck and embankment. The gaps underneath railway track slabs are not easily detectable by common nondestructive test methods. A nondestructive test (NDT) based on a wavelet time-frequency concept is proposed for the practical purpose of detecting gaps under track slabs. The method uses a microphone sensor to catch leaked Rayleigh acoustic waves in the air and an accelerometer to measure surface Rayleigh waves on the slab. In order to investigate the possibility of developing the test system, a finite element analysis (FEA) was performed to simulate Rayleigh wave generation on the concrete surface and in the air. A test system module composed of a microphone and an accelerometer, data acquisition system (DAQ), and an analyzer program was also assembled for a small backyard pilot test. It was verified that the new NDT test system could be successfully adapted for detecting gaps underneath railway track slabs and track bed soil. © 2020 by the authors.","FEA; Gap; Leaky rayleigh acoustic wave; Railway track slab; Wavelet",,,,,,"579 RTRP-B137848-04, RTRP-B137848-04","This research was funded by Korea Railway Corporation, KORAIL, grant number RTRP-B137848-04.

In this paper, an algorithm is proposed for calculating objective evaluation parameters of sound quality (including loudness, sharpness and articulation index), considering acoustic characteristics of human external ear, middle ear and inner ear to reflect auditory sensation. A sound quality simulation (SQS) module is coded according to the algorithm. The module is used for evaluating sound quality of road noise from an SUV in three steps. Firstly, interior noise is predicted by integrating finite-element method (FEM), hybrid FE-SEA method, and statistical energy analysis (SEA) for low frequency (20~315 Hz), medium frequency (315~500 Hz), and high frequency (>500 Hz) in 1/3 octave band, respectively. The predicted interior noise SPLs are compared with the measured results, with deviations less than 3dB in average. Secondly, the sound quality parameters are calculated using the predicted SPLs in the SQS module. The predicted and measured loudness, sharpness, and articulation index are compared, with average deviations less than 5%. Finally, the predicted interior noise is filtered by the SQS module in 1/3 octave band, to determine the dominant contribution bands for the sound quality parameters. Several optimized designs are implemented to optimize the sound quality parameters, and validated by experiments. © 2020 SAE International.

It results in variable rotational end restraint for cross-beams, thus variable bending moment distribution. This feature is captured in three-dimensional modelling of through truss bridge structure. However, for preliminary design or rapid assessment of service load effects such technique of analysis may not be available. So an analytical method of assessment of rotational end restraint for cross-beam of through truss bridges was worked out. Two cases – nodal cross-beam and inter-nodal cross-beam – were analyzed. Flexural and torsional stiffness of truss members, flexural stiffness of deck members and axial stiffness of wind bracing members in the vicinity of the analyzed cross-beam were taken into account. The provision for reduced stiffness of the X-type wind bracing was made. Finally, general formula for assessment of rotational end restraint was given. Rotational end restraints for cross-beams of three railway through truss bridges were assessed basing on the analytical method and the finite element method (three-dimensional beam-element modelling). Results of both methods show good agreement. The analytical method is able to reflect effects of some structural irregularities. On the basis of the obtained results the general values of rotational end restraint for nodal and inter-nodal cross-beams of railway through truss bridges were suggested.

However, the damage of the constructions is always a limitation. On the contrary, Non-Destructive Tests (NDT) are fast and cost-effective which make them attractive nowadays. Nevertheless, the results of Ultrasonic Pulse Velocity (UPV) test are highly dispersed. Therefore, it is necessary to combine them along with destructive tests. The purpose of this study is to investigate the feasibility to adopt the Sonic Resonance (SR) test to determine the strength parameters of the concrete. UPV and SR were used in conjunction with the Uniaxial Compression Test. Experimental and numerical analysis were conducted. More than 200 concrete cores from existing constructions were tested and more than 70 Finite Element Method (FEM) models were simulated. The results were correlated, and two empirical equations derived. It was observed that the dispersion of the of SR alone is smaller than the UPV, but also the UPV dispersion can be narrowed as long as the Poisson's ratio is known. © 2020 Vassilis G.

To investigate the live-load behavior of twin girder bridges, the State Highway 52 Bridge over the Snake River was instrumented and studied. The live-load response was monitored by attaching 62 strain gauges on girders, stringers, and intermediate diaphragms at nine cross-sectional locations. The live-load was applied with two trucks that were driven along three predetermined load paths. A finite-element model of the bridge was calibrated with the measured response from the live-load tests. The calibrated finite-element model was used to quantify moment distribution factors and load ratings for the bridge. The finite-element distribution factors were compared with those calculated according to methods provided in the AASHTO standard and LRFD specifications. The distribution factors from both specifications were found to be unconservative for the girders and overly conservative for the stringers. The model also was used to quantify the effect of the transverse diaphragm members on the live-load distribution. Distribution factors were calculated with and without the diaphragm members. The diaphragms were found to increase the distribution of moments by over 20% for both positive and negative moments. © 2020 American Society of Civil Engineers.",,"Beams and girders; Load testing; Specifications; Stringers; Distribution factor; Finite-element distributions; Intermediate diaphragm; Live-load behavior; Minimal redundancy; Moment distribution; Negative moments; Transverse diaphragms; Finite element method",,,,,,"The authors express their gratitude to the Utah Transportation Center (UTC) in partnership with the Mountain Plains Consortium, who provided the financial support for this study.

The experimental results show that compared with externally prestressed normal concrete (PC) box-girder with corrugated steel webs, the externally prestressed RPC box-girder with corrugated steel webs has higher ultimate bearing capacity, higher cracking strength, better anti-cracking performance and durability.

The parameters considered for this study are damage detection, localization, and quantification, for both single and multiple damage cases. The objective is to propose the most efficient method for both these cases. A beam of length 3.15m is analyzed using a self-developed finite element model-based program on MATLAB™ and damage is simulated by reductions in effective flexural rigidity. Based on the aforementioned parameters, it is found that the FC Method is most suitable for single damage detection while the MSECR method is most suitable for multiple damage detection. © 2020, Associated Cement Companies Ltd.

Although complex analysis of welded joints gives satisfactory results, factors that modify the endurance limit are common in industrial use. The endurance limit-modifying factors given in reference books are unable to generalize to all types of welded joints. Furthermore, cracks in fillet welded T-joints are likely to start from the toe of the weld bead; however, the weld throat thickness is considered in the calculation of the strength of a welded joint. In this study, we examined the stress concentrations of load-carrying welded T-joints considering bead shape and thickness via finite element analysis and verified the model experimentally. We utilized an electromechanical cylinder to carry out experiments to obtain stresses near the weld bead via strain gauges. The submodeling technique was implemented to obtain results in the regions of stress concentrations as accurately as possible. The results of finite element analysis were in good agreement with experimental results. The present study showed that the ratio of weld throat thickness to plate thickness significantly affects the stress concentration factors of load-carrying welded joints. The maximum stress decreased significantly depending on bead shape and thickness. Endurance limit-modifying factors gathered via analyses assuming the weld as a notch and considering plate thickness could be used in the fatigue strength calculations of welded joints. © 2020, The Brazilian Society of Mechanical Sciences and Engineering.","Fatigue strength; Finite element analysis; Notch effect; Steel; Submodeling; Welded joint","Bridges; Factor analysis; Finite element method; Steel; Stress concentration; Welded steel structures; Welding; Welds; Complex analysis; Fatigue strength; Machine construction; Modifying factors; Notch effect; Stress concentration factors; Sub-modeling technique; Submodeling; Fatigue of materials",,,,,"Akdeniz Üniversitesi; Firat University Scientific Research Projects Management Unit, FÜBAP: FBA-2017-1940","This work was supported by the Scientific Research Projects Coordination Unit of Akdeniz University (Project No.: FBA-2017-1940).","This work was supported by the Scientific Research Projects Coordination Unit of Akdeniz University (Project No.: FBA-2017-1940).

Finite-element analysis (FEA) was used to construct flexural strength-reduction curves for tub girders with various out-of-flatness magnitudes covering a range of girder cross sections and spans. Tub bottom flange slenderness ratios between 25 and 120 were modeled as covering the practical range. Models were built with coexisting out-of-flatness in both webs and flanges. The appropriate residual stress pattern was created using heat analysis. Models were laterally supported to ensure the local buckling limit state controls. Both 344.7-MPa (Grade 50 Steel) and 689.4-MPa (Grade 100 Steel) yield steel plates were considered with elastic-perfectly plastic material behavior. Large deflection theory was used to iteratively capture the secondary moments due to out-of-flatness. The current tolerance of D/150 out-of-flatness for the fascia web of an I-shaped plate girder was shown to implicitly accept a 20% strength reduction. Results showed that compressive flexural design formulas for tub girders in current standards conservatively reduce the strength to account for local buckling. Code adoption of bf/200 is recommended for the tub girder bottom flange out-of-flatness tolerance, where bf represents the bottom flange width. © 2019 American Society of Civil Engineers.","Box girders; Finite-element analysis; First buckling mode; Flexural strength; Imperfection; Out-of-flatness; Residual stresses; Strength reduction; Tub girders","Bending strength; Box girder bridges; Buckling; Defects; Fasteners; Finite element method; Flanges; Residual stresses; Structural panels; Box girder; Buckling mode; Elastic-perfectly plastic material; Flange local buckling; Out of flatness; Secondary moments; Slenderness ratios; Strength reduction; Beams and girders",,,,,,,,,,,,,,,,"(2002) AASHTO Standard Specifications for Highway Bridges, , AASHTO. 17th ed.

The bridge consists of prismatic separated dual box girders with an overall length of 136 m (1+40+54+40+1 m). The bridge was hit by a tanker on August 5, 2006, and three supporting brackets near Pier 5 were severely damaged. An attempt was made to repair the bridge to recover its original strength. This study evaluated the effectiveness of the repairs, the postrehabilitation properties, and the strength of the damaged brackets and the bridge using static and dynamic field load tests and finite-element method (FEM) analyses. The results show that the finite-element (FE) model and the load tests provide a comprehensive evaluation of the behavior of the bridge structure. The accuracy and reliability of the FE model was investigated and validated through a field loading test. The field loading test and the computer simulation indicated that the original performance of the Wanjiang Bridge was restored and its strength satisfies the design requirements so that any vehicle with load of less than 30 t would be allowed to cross. © 2019 American Society of Civil Engineers.","Analytical and experimental evaluation; Continuous prestressed concrete (PC) girder bridge; Finite-element method (FEM); Load-carrying capacity; Loading test; Ship collision; Structural safety; Supporting bracket","Bridges; Concrete beams and girders; Fasteners; Load limits; Load testing; Prestressed concrete; Experimental evaluation; Girder bridges; Loading tests; Ship collision; Structural safety; Supporting bracket; Finite element method",,,,,"LY17E080022; National Natural Science Foundation of China, NSFC: 51778147; China Postdoctoral Science Foundation: 2016M600352; Science and Technology Department of Zhejiang Province: 2015C33222","The authors appreciate the financial support from the Natural Science Foundation of China (Grant No. 51778147), the Provincial Natural Science Fund of Zhejiang (Grant No. LY17E080022), the China Postdoctoral Science Foundation (Grant No. 2016M600352), and the Science and Technology Agency of Zhejiang province (Grant No. 2015C33222).",,,,,,,,,,"Abdessemed, M., Kenai, S., Bali, A., Kibboua, A., Dynamic analysis of a bridge repaired by CFRP: Experimental and numerical modeling (2011) Constr.

The shift of pier is caused by the movement of soil under the substructure that has been indicated since 2012. P2 pier is constructed over clay shale. Clay shale has characteristics when in dry condition, the soil has high shear strength, but when the soil absorbs water or expose in open air, the soil loses its strength. P2 pier displacement results in extreme structural damage, so immediate handling is needed to stop the shifting of the pier. Analysis and reinforcement study are carried out using finite element method. Based on analysis, it is discovered that the existing slope stability safety factor of P2 pier is 1.09, indicating that the soil movement can occur if the clay shale is disrupted. Reinforcement is designed to mitigate the shift of the P2 pier by adding 38 pile foundations to the existing foundation configuration. Each pile has diameter of 1.2 meter with a depth of 30 meter across the existing slip circle. Reinforcement increases the slope stability safety factor to 1.25, indicating that the P2 pier after reinforcing is in safe condition. © Published under licence by IOP Publishing Ltd.",,,,,,,,,,,,,,,,,,"Atmaja, H.K., Kasyful, M., Pengaruh Peningkatan Infrastruktur Terhadap Pertumbuhan Ekonomi di Kota Sibolga (2015) Jurnal Ekonomi Dan Keuangan, 3; Sukwika, T., Peran Pembangunan Infrastruktur Terhadap Ketimpangan Ekonomi Antarwilayah di Indonesia (2018) Jurnal Wilayah Dan Lingkungan, 6 (2), pp. 115-130; Haris, A., (2005) Pengaruh Penatagunaan Tanah Terhadap Keberhasilan Pembangunan Infrastruktur Dan Ekonomi; Dorodjatoen, A.M.H., The Emergence of Jakarta-Bandung Mega-Urban Region and Its Future Challenges (2009) Jurnal Perencanaan Wilayah Dan Kota, 20, pp. 15-33; Jasamarga, (2019) Peta Ruas Tol Purbaleunyi (Purwakarta-Bandung-Cileunyi); Zarkasi, I., Irpanni, H., Ariefien, H., Penanganan Jembatan Cisomang Ruas Tol Cikampek-Padalarang: Pembelajaran Penanganan Jembatan Akibat Pergerakan Tanah Clay Shale (2018) Jurnal HPJI, 4, pp. 25-36; Imran, I., Budiono, B., Adhi, K., Aryanto, A., (2005) Sistem Jembatan Girder Menerus: Studi Kasus Pada Perencanaan Jembatan Cisomang; Nurhadi, M.D., Hendry, Somantri, A.K., (2017) Perancangan Perkuatan Struktur Bawah Jembatan Cisomang; Hardiyatmo, H.C., (2014) Tanah Ekspansif: Permasalahan Dan Penanganan; Hardiyatmo, H.C., (2010) Stabilisasi Tanah Untuk Pekerjaan Jalan; Irsyam, M., Sahadewa, A., Boesono, A., Soebagyo, Pengaruh Strength Reduction Tanah Clay Shale akibat Pelaksanaan Pemboran Terhadap Nilai Daya Dukung Pondasi Tiang di Jembatan Suramadu Berdasarkan Analisis Hasil Tes OC (2007) Jurnal Teknik Sipil ITB, 14, pp. 69-82; Shouman, M., Hendry, Yuswandono, M., Febriansya, A., Perancangan Perkuatan Fondasi Tiang Pasca Pelaksanan Jembatan Kalanggeta, Kabupaten Serang, Provinsi Banten (2018) 9th Industrial Research Workshop and National Seminar (IRWNS); Brinkgreve, R.B.J., Kumarswamy, S., Swolf, W.M., (2016) PLAXIS 2016; Nasional, B.S., (2017) Persyaratan Perancangan Geoteknik BSN","Hendry, H.; Department of Civil Engineering Department, Jln.

To allow the single stiffener to be considered instead of the plate requires an assumption that the stress in the structure is carried through the stiffeners and not the attached plate, and therefore the stresses in each member do not interact. However, this assumption is not completely realistic so effective breadth has been developed to calculate an area of plate, carrying a uniform stress ensuring that the stresses are close to those in the larger structure. It is commonly used to design uniformly loaded structures such as ships, bridges and aircraft; allowing the replacement of complex and computationally expensive structural units with smaller monodimensional elements. Despite the effective breadth having been widely investigated for metallic structures specific derivations for composites are still limited, as they are still based on these original definitions. Almost every study that has been performed leads to the creation of a new formula but these studies tend not to compare back to the original larger structural units. This paper investigates the use of effective breadth for composite top-hat stiffened structures by comparing a number of definitions of effective breadth. It is shown that there is a wide variation in the different definitions and that comparison to realistic structural units is important, to ensure that the individual beams are replicating the behaviour of the full structure. The position of the stiffener is important, with intersection stresses calculated accurately but edge stresses giving poorer results, and a new formula is proposed to account for this. © 2019","Composites; Finite element analysis; Grillage analysis; Rule development; Stiffened structures","Bridges; Composite materials; Finite element method; Structural design; Effective breadth; Grillage analysis; Loaded structures; Metallic structures; Rule development; Stiffened composite structure; Stiffened structures; Structural unit; Plates (structural components); accuracy assessment; bridge; finite element method; numerical model; stiffness; stress analysis; structural response",,,,,"ISO 12215 WG18; Ministry of Defence, MOD","The authors would like to thank the UK Ministry of Defence and ISO 12215 WG18 for their support and without whom this research would not have been possible.","The authors would like to thank the UK Ministry of Defence and ISO 12215 WG18 for their support and without whom this research would not have been possible.

Total length of the bridge is 606 m with a 188 m main span, one of the longest in Japan. In order to prepare for any future traffic lane expansion, the arrangement of stay cables with suspension in one plane was adopted. Two stay cables were arranged in parallel and fixed near the structure center. Therefore, wake galloping and wake-induced flutter was of concern as aerodynamic vibration phenomena particular to parallel cables. Then, after studying parameters such as stay cable interval and outside diameter, wind tunnel tests were carried out. A vibration-control damper was installed to satisfy the necessary structural damping for the suppression of vibrations caused by wake galloping, and also by rain vibration that occurs during rainfall. In addition, for the stay cable anchorage installed on the main girder of the suspension in one plane structure, steel shell structure was adopted to efficiently transmit the stay cable tension concentrated at anchorage to the main girder. Based on the actual design of existing bridges, the design method of each member such as bearing plate and guide pipe was determined, and finally the force flow was confirmed using three-dimensional FEM analysis. Furthermore, in the main tower, the saddle structure was adopted so stay cables can be exchanged one by one for easy maintenance. This is the first time the saddle structure was used in Japan. © fédération internationale du béton (fib).","Aerodynamic vibration phenomenon; Extradosed bridge; Saddle structure; Suspension in one plane; Vibrationcontrol damper","Anchorages (foundations); Beams and girders; Bridge cables; Concrete buildings; Concrete construction; Design; Rain; Suspensions (components); Suspensions (fluids); Vibration control; Wakes; Wind tunnels; Aerodynamic vibrations; Corrugated steel webs; Design and construction; Extradosed bridge; Outside diameter; Structural damping; THREE-DIMENSIONAL FEM; Wind tunnel tests; Cable stayed bridges",,,,,,,,,,,,,,,,"Hosotani, Construction of Intermediate Support on Pier of a Large Extradosed Bridge by Incremental Launching Method (2018) Proceedings for the 2018 Fib Congress, , Melbourne, Australia; (2012) Wind-Resistance Design Handbook for Highway Bridges","Naka, T.; Construction Engineering Department, Japan; email: nk-tks00@pub.taisei.co.jp","Zhao B.Lu X.",,"fib.

Firstly, based on genetic algorithm with better global optimization performance and nonlinear programming with better local optimization performance characteristics, a hybrid optimization algorithm based on genetic algorithm and nonlinear programming is proposed, which can ensure the local optimization as far as possible under the premise of global optimization. Then, in order to verify the feasibility of the algorithm, an improved genetic algorithm was used to update the finite element model of the prestressed concrete continuous rigid frame bridge with a health monitoring system: The real modal parameters of the bridge are obtained from the measured acceleration data and the measured frequency is taken as the objective function. Then the elastic modulus of the continuous rigid frame bridge is selected as the parameter to be updated, and the response surface model is constructed for optimization calculation, and the model updating of the continuous rigid frame bridge is realized. Finally, in order to verify the efficiency of the algorithm, the traditional genetic algorithm is used to update the bridge model and compared with the improved genetic algorithm. The results show that the improved genetic algorithm has significantly improved solution accuracy compared with traditional optimization algorithms, which can better reflect the real stress state of the structure and provide a new idea for concrete bridge finite element model updating and damage identification. © fédération internationale du béton (fib).","Bridge health monitoring; Continuous rigid frame bridge; Damage identification; Finite element model updating; Improved genetic algorithm","Concrete buildings; Concrete construction; Damage detection; Finite element method; Global optimization; Modal analysis; Parameter estimation; Prestressed concrete; Rigidity; Continuous rigid frame bridges; Finite-element model updating; Health monitoring system; Hybrid optimization algorithm; Optimization calculation; Performance characteristics; Response surface modeling; Traditional genetic algorithms; Genetic algorithms",,,,,,,,,,,,,,,,"Berman, A., Mass matrix correction using an incomplete set of measured modes (1979) AIAA Journal, 17, pp. 1147-1148; Huang, Q., Zhang, L.Z., Updating of bridge finite element model based on optimization design theory (2008) Journal of Harbin Institute of Technology, pp. 246-249; Kong, X.R., Qin, Y.L., Luo, W., GA-PSO algorithm model updating (2009) Mechanics in Engineering, 31, pp. 56-60. , (in Chinese); Kwon, K.S., Lin, R.M., Robust finite element model updating using Taguchi method (2005) Journal of Sound & Vibration, 280, pp. 77-99; Li, H.N., Gao, D.W., Yi, T.H., Research status and progress of structural health monitoring system in civil engineering (2008) Advances in Mechanics, pp. 151-166. , (in Chinese); Liu, Y., (2008) High Performance Optimization Algorithms and Model Updating of Structures, p. 152. , Harbin Institute of Technology.

Tensile forces can reduce the punching capacity of the slabs, however, few studies have been carried out to quantify this effect. An experimental, numerical and theoretical investigation has been carried out, in which 5 1.65x1.65x0.12 m slabs have been tested under a point load and different degrees of unidirectional tensile force. Numerical predictions were made with FEA software ABAQUS and, from the theoretical point of view, the Compression Chord Capacity Model (CCCM) was extended to take into account the effect of in-plane tensile forces in the punching strength of the slabs. The experimental results showed that the ultimate punching load decreases linearly with the applied tensile force, and if that tensile force cracks the slabs, such reduction is higher. Results obtained with FEA and CCCM are in agreement with the observations made at the laboratory. © fédération internationale du béton (fib).",,"ABAQUS; Box girder bridges; Shear flow; Steel bridges; Compression chords; Continuous box girders; In-plane compression; Intermediate support; Numerical predictions; Punching shear strength; Theoretical investigations; Theoretical points; Tensile strength",,,,,,,,,,,,,,,,"Abrams, J.H.

Newton iteration method is used to compile macro instructions, and the vehicle load in the finite element model is quickly and automatically loaded. GA algorithm and BP neural network were used to find the optimal parameters. Combined with BP algorithm, the function near the design point is reconstructed and the modified results of each parameter are calculated by Monte Carlo method. The joint correction framework combines the advantages of two algorithms. GA algorithm reduces optimization time and speeds up iterative convergence. BP network can extend a single correction to more parameters, making the objective function diversified and the correction more accurate. Combined with the data from the actual bridge load test, a more accurate objective function is obtained, and the optimal results and parameters are obtained iteratively. Results show that the combined GA algorithm and BP neural network have a significant effect on correcting the long-span nonlinear structure model, and the error is within 5%, which proves that the method can be extended to a variety of complex bridge types. © fédération internationale du béton (fib).","BP neural network; GA algorithm; Model modification; Suspension bridge","Backpropagation; Concrete buildings; Concrete construction; Genetic algorithms; Iterative methods; Load testing; Monte Carlo methods; Neural networks; Parameter estimation; BP neural networks; Bridge load tests; Iterative Optimization; Local Convergence; Model modification; Newton Iteration Method; Nonlinear structure; Objective functions; Finite element method",,,,,,,,,,,,,,,,"Deng, M.Y., Ren, W.X., Wang, F.M., Based on the finite element model of static response surface, the method is modified (2008) Experimental Mechanics, 23 (2), pp. 103-109. , (in Chinese); Han, W.S., Vehicle-bridge coupling vibration analysis system based on model modified grillage method (2011) China Journal of Highway, 24 (5), pp. 47-55. , (in Chinese); Shan, D.S., Finite element model modification of the bridge based on the test data (2014) Journal of Civil Engineering, 47 (10), pp. 88-95. , (in Chinese); Tian, Z.C., Peng, T., Cheng, Z.Q., Study on the static and dynamic stratified finite element model modification of Dongping bridge in foshan (2007) Vibration and Impact, 26 (6), pp. 162-165. , in Chinese; Xu, Z.B., Zheng, J.S., Zheng, Y.L., (2003) Bionics in Computational Intelligence: Theory and Algorithms, , Science Press, Beijing, China.

Firstly, the basic theory of model updating is expounded. The objective function is constructed by using deflection, frequency and Modal Assurance Criteria (MAC). The GA is introduced to encode the parameters into chromosomes and simulate the natural evolution process of subgroup selection, crossover and mutation to search for the optimal solution of multivariable problems. Secondly, the load test of the concrete-filled steel tube arch bridge is briefly described; the initial FEM is established, as well as the calculation and test data are compared. Finally, Monte Carlo method is used for sensitivity analysis to determine the updating parameters. The FEM updating is based on the MATLAB platform, and the updated responses are compared and analyzed. The results show that the GA based on MATLAB is effective in the model updating of concrete-filled steel tube arch bridge and has good global optimization ability. Compared with the traditional optimization algorithm, the GA combined with MATLAB is insensitive to the initial input of parameters, avoids the problem of local convergence and improves the efficiency of model updating. The updated calculated values are basically consistent with the test values, and all errors are within 5%. The maximum error of partial load is 11%, and the rests are all controlled within 10%. Compared with the model before updating, the vibration characteristics after updating are well improved. The errors of the first third order vertical bending are 9%, 12% and 5% respectively, which are in good agreement with the test values. © fédération internationale du béton (fib).","Bridge engineering; Genetic algorithm; Model updating; Static and dynamic characteristics; The objective function","Arch bridges; Arches; Chromosomes; Concrete buildings; Concrete construction; Concretes; Efficiency; Errors; Finite element method; Global optimization; Iterative methods; Load testing; MATLAB; Monte Carlo methods; Sensitivity analysis; Steel bridges; Tubular steel structures; Concrete-filled steel tube arch bridge; Crossover and mutation; Finite-element model updating; Iterative Optimization; Modal assurance criterion; Optimization algorithms; Static and dynamic tests; Vibration characteristics; Genetic algorithms",,,,,,,,,,,,,,,,"Cui, F., Yuan, W., Shi, J., Structural damage identification method based on static strain and displacement measurement [J] (2000) Journal of Tongji University (Natural Science Edition), (1), pp. 5-8. , (in Chinese); Fang, Z., Zhang, G., Tang, S., Chen, S., Dynamic finite element modeling and model updating of concrete cable-stayed bridges [J] (2013) China Journal of Highway and Transport, 26 (3), pp. 77-85. , (in Chinese); Han, W., Wang, T., Li, Y., Li, Y., Huang, P., A Practical Updating Method for Finite Element Model of Long-span Steel Truss Suspension Bridge [J] (2011) Journal of Transportation Engineering, 11 (5), pp. 18-27. , (in Chinese); Li, Y., (2010) Development and Verification of the Beam-Grid-Vehicle-Bridge Coupling Vibration Program Based on Model Updating [D], , Chang'an University.

Because the finite element model established according to the design parameters was adopted by engineers based on their own experience, various simplifications and assumptions. The finite element model calculated according to the design parameters does not reflect the actual bridge model. In order to obtain the finite model of the real bridge through the modification of the finite element software, the ANSYS optimization module is generally used to solve iteratively, but the unfriendly pre-processing module of the ANSYS is not suitable for the application of actual bridge structures. This paper proposes a method of modifying the static load test data of the finite element model based on the sensitivity coefficient to obtain the actual bridge model. This method provides optimization module through MTLAB, MIDAS provides structural stiffness matrix, and introduces sensitivity coefficient to establish the relationship between optimization module and structural stiffness matrix, so as to obtain a finite element model that reflects the actual bridge structure. The above method was used to verify the actual bridge, and the static deflection of a city bridge was corrected. The error between the corrected value and the measured value was within 5%.

The project background is a three-way intersection. The intersection has three road. A crossing bridge is designed to help people cross the streets. The example bridge’s dynamic characteristics and vibration serviceability need to be analysed. The finite element model of the bridge is established by the midas/Civil software and the analysis of the model is done. Finite element analysis and time history analysis are used to analyse the human-induced vibration and vibration serviceability. The results show that the pedestrian bridge has different dynamic characteristics compared to other normal bridges. Live load time history method can be used to calculate the dynamic response of the bridge. As the natural frequency increases, the dynamic response is increasing too. The vibration mode of different vibration mode is different. The maximum acceleration response satisfies the requirement of British specifications. If the load is applied to the straight-line part, the response curve has more cyclical changes compared to the condition that load is applied to the curved line part. Peak response value often appears in the middle part of the whole loading period and the peak acceleration value is 0.0319m/s2, which is far less than the limit of the specifications.

In the presented paper the digital twin method is used for making assessments of safety, durability and reliability of bridge structures. Although some numerical modelling is often done when an existing bridge is evaluated, it usually does not involve the simulation of real behaviour under service and environmental loads including chloride ingress, reinforcement corrosion and assessment of ultimate load carrying capacity. The digital twin concept in addition includes an important aspect of the digital twin calibration and validation using the real monitoring data. The paper presents a chemo-mechanical model covering initiation and propagation of chlorides or carbonation. This model is combined with the nonlinear modelling of cracking, bond failure and reinforcement yielding (Cervenka and Papanikolaou (2008). The paper extents the previously developed model by the authors Hájková et al. (2019), Jendele, Šmilauer and Červenka (2014). The models were implemented in ATENA software and are validated on experimental data. The developed models can be efficiently used in large scale analysis of real engineering problems as demonstrated on applications to an existing bridge structures in Germany.

For steel-concrete composite beams, shear studs are the key components to connect steel beams with concrete slabs. The main function of shear studs is to resist the longitudinal shear force, horizontal slip and lifting effect between the steel beam and the concrete slab, which makes them cooperative stress and cooperative deformation, so it is necessary to study the bearing capacity and mechanical behavior of the shear studs. Firstly, this paper describes the design and test results of shear stud push-out-tests, and analyzes the mechanical behavior and failure mode of shear stud. Then adopts the finite element software ABAQUS to simulate the shear stud push-out-tests. And the calculated results are compared with the test results to verify the rationality of the model. Through the analysis of the parameters, the influence factors on the ultimate shear bearing capacity of steel-concrete beam shear studs are explored. Finally, it is concluded that the effect of the diameter and height of shear studs as well as the strength grade of concrete on the bearing capacity of shear studs, which could provide a relatively reliable theoretical basis and reference for improving shear studs in practical engineering. © fédération internationale du béton (fib).","Numerical modeling; Parameter analysis; Shear bearing capacity; Shear studs; Steel-concrete composite beam","ABAQUS; Bearing capacity; Bearings (machine parts); Cable stayed bridges; Composite beams and girders; Composite structures; Concrete buildings; Concrete construction; Concrete slabs; Finite element method; Nails; Shear flow; Software testing; Steel beams and girders; Studs (structural members); Compression performance; Long span cable stayed bridges; Mechanical behavior; Practical engineering; Shear bearing capacity; Steel concrete composite beam; Steel-concrete beams; Tensile performance; Concrete beams and girders",,,,,,,,,,,,,,,,"Guezouli, Lachal, Numberical analysis of frictional contact effects in push-out tests (2012) Engineering Structures, 40, pp. 39-50; Liu, H., Geng, F., Study on shear bearing capacity of shear stud considering construction error (2019) Traffic Science and Engineering, 35 (3), pp. 72-78. , (in Chinese); Liu, M., Li, S., Zhang, Q., Study on the influence of shear performance parameters on clustered shear studs (2019) Journal of Huazhong University of Science and Technology (Natural Science Edition), 47 (7), pp. 19-23. , (in Chinese); Ollgaard, A., Slutter, A., Fisher, A., Shear strength of stud connectors in lighter-weight and normal-weight concrete (1971) AISC Engineering Journal, 8, pp. 55-64; Qin, B., Study on nonlinear finite element simulation of shear stud launch test (2018) Sichuan Architecture, 38 (6), pp. 199-201. , (in Chinese); Tong, Z., Zheng, Z., Peng, X., Measuring and calculating the shear stiffness of shear stud in the specimen (2011) Steel Structure, 26 (1), pp. 27-30. , (in Chinese); Zhou, Y., Pu, Q., Shi, Z., Liu, Z., Study on the group mechanical properties of shear connectors in steel-concrete composed section of cable bridge (2017) Journal of Railways, 39 (10), pp. 134-141. , (in Chinese)","Jiao, D.; School of Highway, China; email: 2750421362@qq.com","Zhao B.Lu X.",,"fib.

Crack formation may occur in the end zones of these elements due to tensile splitting, spalling and bursting actions. Investigation of these zones is typically done by means of analytical analysis, strut and tie modelling, 2D linear or nonlinear analysis, or full 3D nonlinear analysis. Especially challenging in this last approach is the modelling of the force transfer from the strands to the surrounding concrete as it defines the magnitude of the tensile stresses. This paper presents a 3D nonlinear analysis of three prestressed bridge girders, experimentally investigated by O'Callaghan et al., Material modelling, steel-concrete interaction properties, as well as convergence problems are addressed systematically. The comparison indicates that good agreement is obtained for the location, size and extent of the experimentally observed cracks. In addition, based on an assessment of measured strand rebar strains, a friction coefficient of 0.5 can be adopted, although the comparison for values up to 0.7 is practically equal. The results prove that 3D nonlinear analysis provides excellent insight in the behaviour of the end zones of pretensioned girders which opens perspectives for an end zone design based on this type of analysis. © fédération internationale du béton (fib).","End zone; Finite element analysis; Friction model; Pretensioned girder; Spalling","Concrete buildings; Concrete construction; Finite element method; Friction; Nonlinear analysis; Structural design; Analytical analysis; Convergence problems; Friction coefficients; Loadbearing structure; Pre-tensioned concrete; Prestressed bridge girders; Pretensioned concrete beams; Steel-concrete interactions; Concrete beams and girders",,,,,,,,,,,,,,,,"(2012) AASHTO LRFD Bridge Design Specifications, , AASHTO, USA: Department of Transportation; (2016) Abaqus 6.14 Analysis/Cae User’s Guide, , Abaqus, Providence: Dassault Systèmes; Abdelatif, A., Owen, J., Hussein, M., Modelling the prestress transfer in pre-tensioned concrete elements (2014) Finite Elements in Analysis and Design, 94, pp. 47-63; Arab, A., Badie, S., Manzari, M., A methodological approach for finite element modeling of pretensioned concrete members at the release of pretensioning (2011) Engineering Structures, 33, pp. 1918-1929; Ayoub, A., Filippou, F., Finite-Element Model for Pretensioned Prestressed Concrete Girders (2010) Journal of Structural Engineering, 136, pp. 401-409; Kannel, C., French, J., Stolarski, H., (1998) Release Methodolgy of Prestressing Strands, , Minnesota, USA: Minnesota Department of Transportation; (2010) CEB FIB Model Code for Concrete Structures 2010, , Model Code, Switzerland: Comité Européenne du Béton (CEB) - Fédération internationale du Béton (FIB); O’Callaghan, M., Bayrak, O., (2008) Tensile Stresses in the End Regions of Pretensioned I-Beams at Release, , Texas, USA: The University of Texas at Austin; Oliva, M., Okumus, P., (2011) Finite Element Analysis of Deep Wide Flanged Pre Stressed Girders to Understand and Control End Cracking, , University of Wisconsin-Madison; Steensels, R., Vandewalle, L., Vandoren, B., Degée, H., A two-stage modelling approach for the analysis of the stress distribution in anchorage zones of pre-tensioned, concrete elements (2017) Engineering Structures, 143, pp. 384-397; Taqieddin, Z., (2008) Elasto-Plastic and Damage Modeling of Reinforced Concrete, , Louisiana, USA: Louisiana State University; Van Meirvenne, K., De Corte, W., Boel, V., Taerwe, L., Non-linear 3D finite element analysis of the anchorage zones of pretensioned concrete girders and experimental verification (2018) Engineering Structures, 172, pp. 764-779; Yapar, O., Basu, P., Nordendale, N., Accurate finite element modeling of pretensioned prestressed concrete beams (2015) Engineering Structures, 101, pp. 163-178","De Corte, W.; Structural Engineering Department, Belgium; email: wouter.decorte@ugent.be","Zhao B.Lu X.",,"fib.

This type of failure is induced by the tensile forces through the electric cables to the adjacent poles and cause the consequent collapse. Due to the brittle behavior of concrete, the cracked positions were mostly found near the base of poles due to maximum bending moment. Because the tensile force induced in electric cables occurs from weight above the downed position of collapsed pole. Therefore, the proposed method to prevent this collapse was introduced by reducing the mass of pole above the snapped point, leading to the reduction in tensile force to the adjacent poles, then decreasing the number of collapsed poles respectively. The analytical finite element (FEM) models were employed to determine the optimum position on each type of poles in order that the weight induced above those parts would not be able to transfer adequate forces to topple adjacent poles. Carbon fiber reinforced polymer (CFRP) and steel plates were then introduced to strengthen the existing poles and the poles in future manufacturing process consecutively. The experiments were conducted and compared to the analytical results. It is indicated that the utility poles were strengthened and the tensile forces induced by the weight above the toppled positions could be reduced significantly. © 2022 River Publishers.",,"Accidents; Cable stayed bridges; Cables; Carbon fiber reinforced plastics; Concretes; Steel fibers; % reductions; Brittle behavior; Cable lines; Finite element modelling (FEM); Maximum bending moments; Optimum position; Reporting statistics; Storm line; Tensile forces; Thailand; Poles",,,,,,,,,,,,,,,,"(2017) The Instruction of Standard Drawing of Electric Prestressed Concrete Poles 12m (GW), , Metropolitan Electricity Authority, Products and Transportation Department, 12m (BM 3.5T-m), 12.35m (BM 6.5T-m); (2008) MorYorPhor.1508-51 The Standard of Structure Strengthening Reinforced Concrete Structures with Composite Fibre Materials, , Ministry of Interior, Department of Public Works and Urban Planning, Bangkok; Vivek, B., Sharma, S., Raychowdhury, P., Ray-Chaudhri, S., A Study on Failure Mechanism of Self-Supported Electric Poles through Full-Scale Field Testing (2016) Engineering Failure Analysis, 77, pp. 102-117. , August; Suchat, S., Atavit, S., The stress analysis is electric poles with CFRP to prevent the consecutive demolishing from car accidents (2018) The 4th International Conference on Engineering, Applied Sciences and Technology, ICEAST, pp. 1035-1038","Arthit, P.; Department of Civil Engineering, Thailand; email: art_arthit@hotmail.com

In this paper, the UHPFRC layer combined with cold connectors was developed on top of the orthotropic steel deck (OSD) as UHPFRC-OSD composite structure, expecting to reduce the stresses in critical fatigue details of OSD and improve the durability of pavement. The composite action between the UHPFRC layer and steel deck plate is realized by epoxy resin gluing of connectors on the steel plate or by epoxy glued at the interface between steel and UHPFRC, thus avoiding fatigue details of welding shear connectors used in the construction stage. Fatigue vulnerable welded details are avoided when the OSD plate is stiffened by the UHPFRC layer, leading to enhanced performance and longer fatigue duration. Based on material property test results, material laws of UHPFRC were determined in both compression and tension. Finite element model (FEM) was built for a full-scale UHPFRC-OSD composite bridge deck to analyze the stress level at fatigue vulnerable details and the improvement of local stiffness.

Corrugated steel web reduces the absorption of prestress by web due to its “fold (accordion)” effect. Therefore, the prestress can be introduced to the top and bottom flanges to a greater extent, which makes the mechanical behavior of the structure more reasonable. Taking a 440m curved box girder bridge with corrugated steel webs as a project case, this study deduces a calculation method of prestress introduction efficiency according to the sectional stiffness coordination characteristics, and establishes a model by using finite element analysis software. Combining theoretical analysis, numerical simulation and field measurement, the prestress introduction efficiency of the corrugated steel web composite curved beam bridge is calculated. Comparing the calculation results of the numerical simulation and the field measurement, it is found that the two are basically the same, thereby verifying the correctness of the calculation result of the prestress introduction efficiency. © 2021 Taylor & Francis Group, London.",,"Box girder bridges; Life cycle; Maintenance; Numerical models; Steel bridges; Beams (bridge); Calculation results; Corrugated steel webs; Curved box girder bridges; Curved girder bridges; Field measurement; Mechanical behavior; Prestressed composite beams; Project case; Sectional stiffness; Efficiency",,,,,"2019TD-022; W03020659; 2018-16","The authors gratefully acknowledge the financial support provided by the Program of National Ten Thousand People Plan Science and Technology Innovation Leading Talent (W03020659), Science and Technology Project of Gansu Provincial Department of Transportation (2018-16) and the Innovation Capability Support Program of Shanxi (2019TD-022).",,,,,,,,,,"Chen, Q.F., Xu, Z.D., Hao, T.Z, Prestressintroduction efficiency of composite beam with corrugated web and internal prestress (2017) China Civil Engineering Journal, 50 (12), pp. 72-79. , etal; Eldib, M.

Because of the spacing between every stud and stud in the group studs is too small under action of load, the stress interaction and overlapping influence among studs and the concrete makes the average shear bearing capacity and shear stiffness of every stud in group studs be lower than the calculated values of single stud. In this paper, aiming at the rapid construction steel-concrete composite small box girder and taking the diameter, depth of the studs, transverse and longitudinal spacing between the studs, number of the studs in the group studs and concrete strength grades as parameters, 22 push-out specimens with different stud group were analyzed by the finite element method. It was found that “stud group effect” could not be ignored. On this basis, according to analysis of the concrete stress distribution and mode in the arrangement of typical group studs, assuming the concrete stress to diffuse and transfer in the internal friction angle of concrete, the simplified calculation model for analyzing the “stud group effect” of the typical steel and concrete composite small box girder was proposed. The quantitative analysis of the proposed method and FEM and the comparison of their results were carried on, it shown there is in good agreement, the maximum error is among 11.4%. © 2021 Taylor & Francis Group, London.",,"Box girder bridges; Concretes; Shear flow; Steel bridges; Studs (fasteners); Box girder; Concrete stress; Construction steels; Rapid construction; Reduction effects; Shear performance; Steel-concrete composite; Steel-concrete composite bridges; Stress overlapping; Stud shear connector; Studs (structural members)",,,,,"Zhejiang University, ZJU; Fundamental Research Funds for the Central Universities","This work is financially supported by the Fundamental Research Funds for the Central Universities of China (2018 Zhejiang University).",,,,,,,,,,"Eurocode 4 - Design of Composite Steel and Concrete Structures-Part 1-1: General Rules and Rules for Buildings (2004) Technical Committee CEN TC Structural Eurocodes, , [S]; (2014) Mechanismpropertiesandexperimentalinvestigation of multi-beam steel concrete composite girder bridge, , HEY.L...

When pouring into the mold, liquid concrete causes some lateral pressure on the mold formwork, which can fix the mobility of fresh liquid, under the combination of pouring effect, concrete self-weight and vibration. The safety of mold formwork is very important to piers construction. Higher concrete pier needs more concrete than lower one. More liquid concrete is always poured at a time, which always induces the bigger lateral pressure. The structure of the mold formwork is always complex and cannot be analyzed theoretically, so finite element method (FEM) analysis may seem to be the only way to solve this problem. An example of high concrete piers in a crossing-sea bridge is conducted to analyze the mechanical behavior of the mold formwork under the effects of self-weight and lateral pressure, using plate elements and beam elements of FEM software.

In order to study the stability and bearing capacity of the cable-stayed bridge with double-sided girder, the finite element model was generated using ANSYS software. Firstly, the elastic stability analysis was carried out in construction and operation stages.

The assessment of fatigue life and, in particular, the prediction of residual service life in the existing buildings are a significant and current engineering problem. A number of studies have been conducted for the stochastic estimation of reliability and the subsequent prediction of the life of various carrying capacity elements and constructions. Numerous numerical methods, mostly based on the finite element method - FEM, have been developed to aid in the understanding of the behavior of the fatigue phenomena. The essential tools for these calculations are provided by fracture mechanics and the reliability theory. Some of approaches used for the fatigue crack prediction are based on stochastic methods. The paper focuses on the probabilistic analysis of fatigue damage of the supporting structure of the crane runway serving the steel warehouse operation of the Vitkovice Machinery Group, Czech Republic. For the prediction of fatigue damage over time, calibration functions for short edge cracks were derived based on the results of the experiment, and the acceptable size of the fatigue crack in damaged structural component under analysis was determined. The stochastic methodology for the prediction of fatigue crack propagation is based on linear fracture mechanics utilizing the Paris-Erdogan's law and Direct Optimized Probabilistic Calculation (DOProC).

In the past eight years, the authors experimentally and numerically investigated the ductile fracture of thick-walled steel structures. On one hand, at the material level, four important issues were studied in detail, including the ductile fracture of welded steels, the ductile fracture of steels at complex stress states, the ductile fracture of steels under cyclic loadings, the ductile fracture of steels after high temperatures, and so on. First of all, for welded steels, the ductile fracture behavior of the base metal, weld and HAZ was investigated based on the smooth flat bar, U-notch flat bars, and V-notch flat bars, and a three-stage and two-parameter ductile fracture model was developed. Therefore, for different and complex stress states, the ductile fracture behavior of steels was tested, including negative triaxiality, low stress triaxiality, medium and high stress triaxiality. One side U-notch and V-notch steel flat bars and shear steel specimens were tested in order to model different stress states. One novel ductile fracture model including the effect of complex stress states was developed. Later, the experiments and FEA results of steel specimens under cyclic loadings were reported. Besides, the post fire mechanical properties and ductile fracture behavior of Q460 and Q690 steels were obtained based on our experimental results and other researchers’ test results. On the other hand, the ductile fracture behavior of steel bridge piers, steel beam-to-columns, steel braces and other steel members were experimentally and numerically investigated in detail at the member level. The ductile crack initiation, propagation and final failure of steel members were obtained during tests. And the mesh size sensitivity during numerical study has been solved through a nonlocal model. Furthermore, a simplified method using fiber beam element model was developed to facilitate engineering application. This study provides abundant basis data and important method to evaluate the ductile fracture of steel structures. © 2020 Taylor & Francis Group, London.",,"Bridge piers; Cyclic loads; Fracture mechanics; Intelligent buildings; Steel bridges; Steel research; Steel testing; Sustainable development; Welded steel structures; Welding; After high temperature; Complex stress state; Ductile crack initiation; Engineering applications; Fiber beam elements; Fracture behavior; Simplified method; Strong earthquakes; Ductile fracture",,,,,,,,,,,,,,,,,,"Papadikis K.Chin C.S.Galobardes I.Gong G.Guo F.",,"CRC Press/Balkema","2nd International Conference in Sustainable Buildings and Structures, ICSBS 2019","25 October 2019 through 27 October 2019",,260199,,9780367430191,,,"English","Sustain.

The beam element model is to clarify that the influence of the residual out-of-plane deformation in main truss structures on the load bearing capacity from the viewpoint of whole bridge. Also, shell element model is to clarify that the influence of severe corrosion damages occurred in many structural members on the load bearing capacity as whole bridge. On the other hand, the influence of assumed support conditions in analytical models were discussed from the analytical results of both type of models, because it will be thought that the performance of shoes deteriorates gradually by long in-service period. The ultimate load bearing capacity was estimated by the critical live load magnification. From the analytical results, the residual out-of-plane deformation of main truss structures in this bridge had little influence on the ultimate load bearing capacity. Also, the ultimate load bearing capacity may decrease up to 20% due to aging deterioration of shoes including corrosion damages.

This paper performs a parametric investigation using finite element analysis (FEA) to study the effects of parapet stiffness on live load-carrying capacity of two-span, three-and four-lane concrete slab bridges. This study analyzed 96 highway bridge cases with varied parameters such as span-length, bridge width, and parapet stiffness within practical ranges. Reinforced concrete parapets or railings, built integrally with the bridge deck, were placed on one and/or both sides of bridge deck. The longitudinal bending moments calculated using the FEA results were compared with reference bridge cases without parapets, as well as AASHTO Standard and LRFD specifications. The FEA results presented in this paper showed that the presence of concrete parapets reduces the negative bending moments by 15% to 60% and the positive bending moments by 10% to 45%. The reduction in longitudinal bending moments can mean an increase in the load-carrying capacity of such bridges depending on the parapet stiffness. This investigation can assist engineers in modeling the actual bridge geometry more accurately for estimating the loadcarrying capacity of existing concrete bridges. Hence, new bridges can be designed by considering the presence of concrete parapets.

In this paper, the effect of size on punching shear has been quantified for transversely post-tensioned deck slabs cast between flanges of precast concrete girders. A 1:2 scaled model of the bridge was constructed in the laboratory, and experimental and numerical analyses were carried out. However, in order to apply these results on a real bridge, simply using the geometrical scale factors is not sufficient and a structural size effect has to be taken into account. Since a full-scale experimental study was not possible due to the costs involved, a numerical approach using finite element analysis software package TNO DIANA was used to model both the prototype and the real bridge, and a comparison was made to estimate the effect of size on the bearing capacity. It was found that increasing the transverse prestressing level had a positive effect on the punching shear strength of the deck slab. Furthermore, a lower size effect was observed with higher transverse prestressing levels. It is concluded that if a suitable size factor is used, either numerical or small-scale experimental studies can be reasonably used to investigate existing structures. © 2020 ISEC Press.","Bearing capacity; Numerical modeling; Punching shear; Scale factor; TNO DIANA; Transverse prestressing level",,,,,,,,,,,,,,,,,"Amir, S., (2014) Compressive Membrane Action in Prestressed Concrete Deck Slabs, 282. , PhD Thesis, Delft, the Netherlands; Bazant, Z.P., Cao, Z., Size Effect in Punching Shear Failure of Slabs (1987) ACI Structural Journal, 84, pp. 44-53; (2012) User’s Manual-Release 9.4.4, , Delft: TNO Building and Construction Research; EN 1991-2, Eurocode 1: Eurocode 1-Actions on Structures-Part 2.

In this study, the buckling strength analyses, including future forecast, were conducted for the vertical member, which has the combined cross-section in actual aging truss bridge. For constructing the analytical model, a simple corrosion progress model was applied to generating the corroded steel surface. In this corrosion progress model, it assumes that corrosion pits are generated by the attack factors which can be decided by some control parameters for corrosion environment, corrosion form and corrosion area. And, the constant number of the attack factors per year fall all over the discretized steel surface. The corrosion surface in the future can be generated numerically by repeating mentioned above. The average thickness calculated from the numerical corrosion surface was applied to the local corrosion area in each analytical model. From these analytical results, a future forecast method applying a corrosion progress model was discussed by focusing on the aging deterioration of the buckling strength. © 2020 ISEC Press.","Corrosion progress model; Elastic buckling; Finite element analysis; Local corrosion; Pitting corrosion; Remaining thickness",,,,,,,,,,,,,,,,,"Yamane, T., Kaita, T., Fukuda, H., Kawami, S., Hirahara, S.R., Kanou, Y., Fujii, T., Analytical Study of Ultimate Load Bearing Capacity for an Aging Pratt Truss Bridge Using FEM, , Proceedings of Bridge Engineering Institute Conference in 2019 (BEI-2019), Yail, J.

The assessment of fatigue life and, in particular, the prediction of residual service life in the existing buildings are a significant and current engineering problem. A number of studies have been conducted for the stochastic estimation of reliability and the subsequent prediction of the life of various carrying capacity elements and constructions. Numerous numerical methods, mostly based on the finite element method – FEM, have been developed to aid in the understanding of the behavior of the fatigue phenomena. The essential tools for these calculations are provided by fracture mechanics and the reliability theory. Some of approaches used for the fatigue crack prediction are based on stochastic methods. The paper focuses on the probabilistic analysis of fatigue damage of the supporting structure of the crane runway serving the steel warehouse operation of the Vitkovice Machinery Group, Czech Republic. For the prediction of fatigue damage over time, calibration functions for short edge cracks were derived based on the results of the experiment, and the acceptable size of the fatigue crack in damaged structural component under analysis was determined.

For the truss bridge, seismic performance evaluation was conducted and it was found that some members were damaged. In order to minimize retrofit work over the railway tracks, the isolation of truss girder was selected. For the truss girder isolation, the constraining effect of the long rail and the running safety of the train were studied. In the retrofit work, in order to minimize the impact on the expressway, railway tracks, and utility facilities, the structural change of the isolation rubber bearings and the displacement of truss girder caused by jacking up had to be studied. The support structure was adopted with a knock-off mechanism, and the effects of jacking up were confirmed by FEM analysis. © 2020 IABSE Congress, Christchurch 2020: Resilient Technologies for Sustainable Infrastructure - Proceedings.

By using new design technologies and durability concepts, through the refined spatial finite element analysis of a 100 m span concrete-filled steel tube arch bridge designed in 2003, the reduction of the load capacity caused by the change of loads and codes is calculated; the errors caused by the lack of design and calculation methods are compared; the decrease of load capacity caused by durability degradation in 10 and 20 years is estimated.

The bridge is immersed in a remote natural environment and is part of the Romanesque Route, which links buildings and structures built in the area during the Romanesque Period. The ""Ponte do Arco"" bridge is a fine example of this type of architecture and, therefore, it deserves devoted conservation and maintenance works. The geometry of the bridge, the internal structure of the pavement and the damage state were characterised by using two non-destructive techniques, photogrammetry and ground penetrating radar, and by performing a damage survey. The data collected was used to perform limit and finite element analyses in order to estimate the structural safety level of the structure.

Nonlinear finite element analysis (NLFEA) can provide a tool to assess safety to obtain a more realistic estimation of the existing safety. Guidelines, based on scientific research, general consensus among peers, and a long-term experience with nonlinear analysis, allow for a reduction of model and user factors. The guidelines have been developed with a two-fold purpose. First, to advice analysts on NLFEA of (P)RC structures. Second, to explain the choices made and to educate analysts, related to the responsibility of limiting model uncertainty. The updated 2017 NLFEA Guidelines can be used for the FE analysis of basic concrete structural elements. Existing concrete structures, like box-girder structures, culverts, cable-stayed bridges and bridge with composite bridge decks can be analysed. The paper contains an overview of the impact of extended validation simulations of tested RC girders with variations in dimensions of cross-sections, amount of reinforcement, strength of concrete. In this way NLFEA can be a reliable tool for re-analysis of existing RC structures. © 2020 IABSE Symposium, Wroclaw 2020: Synergy of Culture and Civil Engineering - History and Challenges, Report.

Taking the construction of a prestressed concrete girder bridge as an example, the development law of the temperature field of concrete hydration heat and the influence of environmental changes on the hydration heat effect are studied. The finite element software ADINA is used to simulate the solid, and the measured and theoretical values are compared and analyzed. The results show that the time-history curve of hydration heat temperature of concrete can be drawn from measured data. In the early stage, the temperature rises rapidly and reaches the peak value in about 7~9 hours, then the temperature drops rapidly and tends to be stable. The maximum difference in temperature between the internal and surface of beam is 10 °C, and the surface of web plate possibly crack. Environmental factors have great influence on the hydration heat effect of concrete, which should be paid attention to in the construction process. © Proceedings of the fib Symposium 2020: Concrete Structures for Resilient Society.

In the presented paper the digital twin method is used for making assessments of safety, durability and reliability of bridge structures. Although some numerical modelling is often done when an existing bridge is evaluated, it usually does not involve the simulation of real behaviour under service and environmental loads including chloride ingress, reinforcement corrosion and assessment of ultimate load carrying capacity. The digital twin concept in addition includes an important aspect of the digital twin calibration and validation using the real monitoring data. The paper presents a chemo-mechanical model covering initiation and propagation of chlorides or carbonation. This model is combined with the nonlinear modelling of cracking, bond failure and reinforcement yielding (Cervenka and Papanikolaou (2008). The paper extents the previously developed model by the authors Hájková et al. (2019), Jendele, Šmilauer and Cervenka (2014). The models were implemented in ATENA software and are validated on experimental data. The developed models can be efficiently used in large scale analysis of real engineering problems as demonstrated on applications to an existing bridge structures in Germany. The example simulation using the digital twin concept show time development of reinforcement corrosion due to chloride ingress, and their impact on the evolution of structural safety and reliability. © Proceedings of the fib Symposium 2020: Concrete Structures for Resilient Society.

Crack formation may occur in the end zones of these elements due to tensile splitting, spalling and bursting actions. Investigation of these zones is typically done by means of analytical analysis, strut and tie modelling, 2D linear or nonlinear analysis, or full 3D nonlinear analysis. Especially challenging in this last approach is the modelling of the force transfer from the strands to the surrounding concrete as it defines the magnitude of the tensile stresses. This paper presents a 3D nonlinear analysis of three prestressed bridge girders, experimentally investigated by O'Callaghan et al., Material modelling, steel-concrete interaction properties, as well as convergence problems are addressed systematically. The comparison indicates that good agreement is obtained for the location, size and extent of the experimentally observed cracks. In addition, based on an assessment of measured strand rebar strains, a friction coefficient of 0.5 can be adopted, although the comparison for values up to 0.7 is practically equal. The results prove that 3D nonlinear analysis provides excellent insight in the behaviour of the end zones of pretensioned girders which opens perspectives for an end zone design based on this type of analysis. © Proceedings of the fib Symposium 2020: Concrete Structures for Resilient Society.

Total length of the bridge is 606 m with a 188 m main span, one of the longest in Japan. In order to prepare for any future traffic lane expansion, the arrangement of stay cables with suspension in one plane was adopted. Two stay cables were arranged in parallel and fixed near the structure center. Therefore, wake galloping and wake-induced flutter was of concern as aerodynamic vibration phenomena particular to parallel cables. Then, after studying parameters such as stay cable interval and outside diameter, wind tunnel tests were carried out. A vibration-control damper was installed to satisfy the necessary structural damping for the suppression of vibrations caused by wake galloping, and also by rain vibration that occurs during rainfall. In addition, for the stay cable anchorage installed on the main girder of the suspension in one plane structure, steel shell structure was adopted to efficiently transmit the stay cable tension concentrated at anchorage to the main girder. Based on the actual design of existing bridges, the design method of each member such as bearing plate and guide pipe was determined, and finally the force flow was confirmed using three-dimensional FEM analysis. Furthermore, in the main tower, the saddle structure was adopted so stay cables can be exchanged one by one for easy maintenance. This is the first time the saddle structure was used in Japan. © Proceedings of the fib Symposium 2020: Concrete Structures for Resilient Society.

Newton iteration method is used to compile macro instructions, and the vehicle load in the finite element model is quickly and automatically loaded. GA algorithm and BP neural network were used to find the optimal parameters. Combined with BP algorithm, the function near the design point is reconstructed and the modified results of each parameter are calculated by Monte Carlo method. The joint correction framework combines the advantages of two algorithms. GA algorithm reduces optimization time and speeds up iterative convergence. BP network can extend a single correction to more parameters, making the objective function diversified and the correction more accurate. Combined with the data from the actual bridge load test, a more accurate objective function is obtained, and the optimal results and parameters are obtained iteratively. Results show that the combined GA algorithm and BP neural network have a significant effect on correcting the long-span nonlinear structure model, and the error is within 5%, which proves that the method can be extended to a variety of complex bridge types. © Proceedings of the fib Symposium 2020: Concrete Structures for Resilient Society.

Firstly, based on genetic algorithm with better global optimization performance and nonlinear programming with better local optimization performance characteristics, a hybrid optimization algorithm based on genetic algorithm and nonlinear programming is proposed, which can ensure the local optimization as far as possible under the premise of global optimization. Then, in order to verify the feasibility of the algorithm, an improved genetic algorithm was used to update the finite element model of the prestressed concrete continuous rigid frame bridge with a health monitoring system: the real modal parameters of the bridge are obtained from the measured acceleration data and the measured frequency is taken as the objective function. Then the elastic modulus of the continuous rigid frame bridge is selected as the parameter to be updated, and the response surface model is constructed for optimization calculation, and the model updating of the continuous rigid frame bridge is realized. Finally, in order to verify the efficiency of the algorithm, the traditional genetic algorithm is used to update the bridge model and compared with the improved genetic algorithm. The results show that the improved genetic algorithm has significantly improved solution accuracy compared with traditional optimization algorithms, which can better reflect the real stress state of the structure and provide a new idea for concrete bridge finite element model updating and damage identification. © Proceedings of the fib Symposium 2020: Concrete Structures for Resilient Society.

The project background is a three-way intersection. The intersection has three road. A crossing bridge is designed to help people cross the streets. The example bridge's dynamic characteristics and vibration serviceability need to be analysed. The finite element model of the bridge is established by the midas/Civil software and the analysis of the model is done. Finite element analysis and time history analysis are used to analyse the human-induced vibration and vibration serviceability. The results show that the pedestrian bridge has different dynamic characteristics compared to other normal bridges. Live load time history method can be used to calculate the dynamic response of the bridge. As the natural frequency increases, the dynamic response is increasing too. The vibration mode of different vibration mode is different. The maximum acceleration response satisfies the requirement of British specifications. If the load is applied to the straight-line part, the response curve has more cyclical changes compared to the condition that load is applied to the curved line part. Peak response value often appears in the middle part of the whole loading period and the peak acceleration value is 0.0319m/s2, which is far less than the limit of the specifications.

For steel-concrete composite beams, shear studs are the key components to connect steel beams with concrete slabs. The main function of shear studs is to resist the longitudinal shear force, horizontal slip and lifting effect between the steel beam and the concrete slab, which makes them cooperative stress and cooperative deformation, so it is necessary to study the bearing capacity and mechanical behavior of the shear studs. Firstly, this paper describes the design and test results of shear stud push-out-tests, and analyzes the mechanical behavior and failure mode of shear stud. Then adopts the finite element software ABAQUS to simulate the shear stud push-out-tests. And the calculated results are compared with the test results to verify the rationality of the model. Through the analysis of the parameters, the influence factors on the ultimate shear bearing capacity of steel-concrete beam shear studs are explored. Finally, it is concluded that the effect of the diameter and height of shear studs as well as the strength grade of concrete on the bearing capacity of shear studs, which could provide a relatively reliable theoretical basis and reference for improving shear studs in practical engineering. © Proceedings of the fib Symposium 2020: Concrete Structures for Resilient Society.

Firstly, the basic theory of model updating is expounded. The objective function is constructed by using deflection, frequency and Modal Assurance Criteria (MAC). The GA is introduced to encode the parameters into chromosomes and simulate the natural evolution process of subgroup selection, crossover and mutation to search for the optimal solution of multivariable problems. Secondly, the load test of the concrete-filled steel tube arch bridge is briefly described; the initial FEM is established, as well as the calculation and test data are compared. Finally, Monte Carlo method is used for sensitivity analysis to determine the updating parameters. The FEM updating is based on the MATLAB platform, and the updated responses are compared and analyzed. The results show that the GA based on MATLAB is effective in the model updating of concrete-filled steel tube arch bridge and has good global optimization ability. Compared with the traditional optimization algorithm, the GA combined with MATLAB is insensitive to the initial input of parameters, avoids the problem of local convergence and improves the efficiency of model updating. The updated calculated values are basically consistent with the test values, and all errors are within 5%. The maximum error of partial load is 11%, and the rests are all controlled within 10%. Compared with the model before updating, the vibration characteristics after updating are well improved. The errors of the first third order vertical bending are 9%, 12% and 5% respectively, which are in good agreement with the test values. © Proceedings of the fib Symposium 2020: Concrete Structures for Resilient Society.

Because the finite element model established according to the design parameters was adopted by engineers based on their own experience, various simplifications and assumptions. The finite element model calculated according to the design parameters does not reflect the actual bridge model. In order to obtain the finite model of the real bridge through the modification of the finite element software, the ANSYS optimization module is generally used to solve iteratively, but the unfriendly pre-processing module of the ANSYS is not suitable for the application of actual bridge structures. This paper proposes a method of modifying the static load test data of the finite element model based on the sensitivity coefficient to obtain the actual bridge model. This method provides optimization module through MTLAB, MIDAS provides structural stiffness matrix, and introduces sensitivity coefficient to establish the relationship between optimization module and structural stiffness matrix, so as to obtain a finite element model that reflects the actual bridge structure. The above method was used to verify the actual bridge, and the static deflection of a city bridge was corrected. The error between the corrected value and the measured value was within 5%. The results show that the method can reflect the actual bridge model. © Proceedings of the fib Symposium 2020: Concrete Structures for Resilient Society.

Its major purpose is enhancing the load carrying capacity, which may come from the stiffening behavior due to membrane action. The difference in behavior between the standard straight beams and the arched beams with different convexities is investigated numerically using Finite Element (FE) software package “ANSYS”. Moreover, according to the needs for making openings, the research studies the effect of opening on the ultimate load and deflection of beams, finally the research investigates the effect of strengthening the opening using Carbon Fiber Reinforced Polymers (CFRP) laminate externally or internally. Two different experimental models (straight, and arched beams) are used for verification with the FE model. And the results show a good agreement with an accepted error. Reinforced concrete semicircular arched beam is modeled with cross section of (150 * 250) mm2 with an inner and outer diameter 1500 and 2000 mm respectively. Full bond is assumed between the CFRP and concrete surface and between the steel reinforcement and concrete. Brick element SOLID65 and SOLID45 was used to represent concrete element and steel plate, respectively. While LINK8 and SHELL41 were used to represent steel reinforcement and CFRP sheets respectively. A parametric study is performed to study the effect of openings in the arched beam as well as its size and shape of opening, the curvature of arch, and the CFRP strengthening effect (number of layers, size and position of the fiber) on load-deflection response, cracking and ultimate loads. The results show that arched beams have better behavior than straight beams with the same span and cross section with and without opening. Deflection has decreased and the ultimate load has increased. The shape of the openings with the same area and different aspect ratios ranges from 1 to 3 in the mid span position have no significant effect on deflection and ultimate load. However, the circular opening has the minimal deflection and the maximum ultimate load. Increasing the height of the opening or its length decreases the ultimate load and rise the deflection. The external strengthening by CFRP laminates rise the ultimate load by various percentages according to CFRP scheme used. © Springer Nature Switzerland AG 2020.","Arched beams; CFRP; Finite element; Openings","Arch bridges; Arches; Aspect ratio; Carbon fiber reinforced plastics; Deflection (structures); Finite element method; Graphite fibers; Reinforced concrete; Soil structure interactions; Strengthening (metal); Carbon fiber reinforced polymer; Cfrp strengthening; Experimental models; External strengthening; Load-deflection response; Nonlinear finite element modelling; Size and position; Steel reinforcements; Concrete beams and girders",,,,,,,,,,,,,,,,"Al-Mutairee, H.M.K., Effect of non-uniform distribution of longitudinal reinforcement on the behavior of reinforced concrete horizontally curved beams with fixed-ends (2013) J.

To alleviate deterioration issues in the orthotropic steel deck (OSD), the steel-ultra high performance concrete (UHPC) lightweight composite deck (LWCD) was proposed for the SDTL Bridge. The LWCD is composed of a 12 mm OSD and a 45-mm UHPC layer, with the two components connected through headed studs. As the first time of LWCD to be used in the long-span flexible bridge, the constructional method of casting UHPC was carefully developed. Considering that the area of the bridge deck is about 65000 m2, the UHPC layer was divided in to 12 zones and the zones were cast step-by-step. Water tanks were deployed on the bridge deck prior to casting UHPC, and during the casting of each UHPC zone, the corresponding water tanks within the current zone were removed. By doing so, the deflection and rotation of the truss girder as well as the tensile stress in UHPC could be controllable. This paper validate the feasibility of the proposed construction method by Finite-element analysis. The maximum torsion angles of the truss girder in each construction stage are less than 0.60°. In addition, the strains of UHPC were recorded during construction to analyse the stress in the UHPC layer. The in-site test indicated that the longitudinal and transverse strain of the UHPC layer were stabilized at -50 PH ~ 50PH and -20 PH ~ -120 PH after steam curing respectively, which have no cracking risk. Thus, the studies in this paper reveal that the proposed constructional method should be suitable in the construction of UHPC on long-span flexible bridges. © Proceedings of the fib Symposium 2020: Concrete Structures for Resilient Society.

Nowadays, designers are implementing this technology to bridge and building special projects located in areas of high seismic risk to improve their performance under earthquake excitations. However, high cost, uncertainty and lack of knowledge in the design have limited its massive use, specially in developing countries. According to the mechanical behavior, BISs are clasiffied in elastomeric bearings, sliding bearings and roller bearings. In this work, the performance of a bi-directional roller bearings system was evaluated; thus, the main objective of this publication is to show the efficiency of a bi-directional roller bearing in improving the structural seismic response of multicolumn systems by means of reducing accelerations and displacements. A numerical code in Matlab was written to simulate the response of the structures under base excitations, the finite element method (FEM) in conjunction with frame elements was used to solve the governing equations. The validation of the numerical model was done by direct comparisons between experimental and numerical data. © 2020 European Association for Structural Dynamics.

Starting from a Finite Element (FE) analysis of a single period (sub-structure) we are able to derive the dynamic behaviour relative to the entire structure. Thanks to a reduction in the degrees of freedom (dofs) of the system and by decomposing the response of the structure on a wave basis, the calculation time is considerably reduced compared to the classic FEM. Numerous structures have been solved with this method but it can not deal easily on the boundary conditions. In this study, we develop a technique of WFE to deal with more general cases of structures constrained in a arbitrary manner as a multiple supported bridge. By using the WFE method, the vectors of dofs and loads will be decomposed on the wave basis in function of loads and reaction forces of the supports. Then, by substituting the boundary condition in this wave decomposition, we obtain a relation between the reaction forces and the loads which permits to calculate the structure response. The numerical applications show that the WFE and FEM agree well and the new method permits to reduce significantly the calculation time. © 2020 European Association for Structural Dynamics.

Forced and ambient vibration tests (AVTs) were carried out in year 2016 on the masonry arch bridge. High-sensitivity piezoelectric accelerometers, a laser vibrometer and a radar interferometer were used to record the structural response. The structure exhibited typical mechanical deterioration phenomena: longitudinal cracks below the vault, material detachment in the voussoir as well in the spandrel wall and damage of the abutments. The damage level of the masonry was even worsened by vegetation grown between the cracks of the stones. The Enhanced Frequency Domain Decomposition (EFDD) method was used to identify the experimental natural frequencies and mode shapes. The experimental modal properties were finally used to calibrate an accurate Finite Element (FE) numerical model developed using a photogrammetric survey based on high-resolution images provided by UAV (Unmanned Aerial Vehicle). In 2017 a restoration process was started aimed to strengthen the tested structure. The experimental tests were repeated at the end of the restoration process. In particular, AVTs were carried out using high-sensitivity accelerometers located in the same positions used before the restoration process. In this paper, the comparison of the natural frequencies and the vibration modes, obtained be-fore and after the restoration process, is presented in order to discuss the effect of severe dam-age on the masonry arch bridge. Furthermore, this comparison is used to gather information on the effect of the restoration activities on the dynamic properties of the masonry arch bridge. The obtained results are crucial for calibrating suitable numerical models in both the different stages using a multidisciplinary approach, which uses UAV technology and photogrammetry techniques. © 2020 European Association for Structural Dynamics.

It is important for bridge engineers to prevent the phenomenon, also called resonance, occurs to provide large amplitude vibrations when the bridge is being forced to vibrate at its natural frequency. This may lead to failure of the bridge structure under resonant vibrations. Common bridge bearings cannot well perform when vibrated large for example elastomeric bearings. This is because they do not have adequate mechanical properties to resist extremely various loads. Therefore, the concept of using metastrcutures to gain superior mechanical properties inspired us to generate a novel bridge bearing model. Because of the nature of dynamic forces on bridge structure, the vibration characteristics of a novel bridge bearing are crucial in analysis and design processes. This paper is the world's first to focus on the comprehension of vibration characteristics of a novel bridge bearing under free vibration. Through finite element method using Fusion 360 software, the numerical investigation of the modal parameters under dynamic condition was carried out for the novel bridge bearing. Also, there is a comparison of the free vibration results between the free-free and fixed boundary condition, in order to observe the influence of various boundary conditions responding to fundamental frequencies and mode shapes of a bridge structure. Additionally, to verify and develop a numerical model of bridge element, the free oscillation characteristics of the novel bridge bearing in different loads and boundary conditions are required. It is confirmed that vibration response measurements and parameters of a novel bridge bearing will be useful for bridge engineers to determine the vibration-based deterioration or to remotely monitor the bridge bearing health, since it is obvious that typical bridge bearing damage appears nearly at resonant frequencies of the bearings. © 2020 European Association for Structural Dynamics.

In the proposed novel methodology, numerically generated data from simulation models are integrated with measurements from the corresponding real structure to achieve high accuracy in identifying and predicting potential structural damages. A truss structure consisting of composite carbon fiber tubes, aluminum elements and steel bolts for the connections is used for the application of the proposed approach. The process begins with the three-dimensional finite element (FE) models of the examined cylindrical parts, developed in robust finite element analysis software simulating each carbon fiber ply and resin matrix. The real structure and FE models are analyzed in dynamic loading to identify their response. After, the complete assembly FE models are updated based on the data from experimental tests that correspond to the conducted analysis tests on composite cylindrical parts. The potential damage of the structure, set as loose bolts defining a multiclass damage identification problem, is then simulated with the optimal models through a series of stochastic FE load cases for different excitation characteristics. The simulated acceleration time series are then be fed in for the training of a supervised Convolutional Neural Network (CNN) classifier. The trained CNN is finally validated on experimentally measured structural states of the truss. Reliable results prove that optimal FE modeling may be used with machine learning techniques to synthesize a damage identification tool despite the uncertainties, which are tackled by the inherent advantage of numerical generated results to simulate arbitrary number of load cases in small amount of type and minimal effort. © 2020 European Association for Structural Dynamics.

As regard the seismic strength of the Cranes it has to be demonstrated via (mostly) a numeric analysis that in the case of the unlikely event of an earthquake the crane isn't breaking apart affecting thus the safety related neighboring equipment. The crane is required to maintain its integrity when subject to the Design Basis Earthquake when it is supposed to hoist the rated load. The goal of this article is to underline the procedure to be followed for nuclear industry cranes in order to obtain sound and credible results for equipment seismic qualification by using the unique analysis features of ANSYS 19. This study is meant to show how a complex structure of an overhead crane may be treated in order to have meaningful results for a decision whether or not such a structure is able to withstand the loads generated by a seismic event. The seismic event is not overloading the crane structure an in comparison with the hoisted load, the seismic stresses stay quite modest. By comparing the overall calculated equivalent stresses with the tensile yield strength we may pull the conclusion that the structure will resist. Based on all the above the crane is considered to be seismically qualified. © 2020 SPIE.","ANSYS 19 software; Crane; Finite elements analysis; Nuclear Industry; Seismic qualification","Bridge cranes; Earthquakes; Gantry cranes; Microelectronics; Nanotechnology; Nuclear fuels; Nuclear industry; Complex structure; Crane structures; Equivalent stress; Safety-Related; Seismic safety; Seismic stress; Structural strength; Tensile yield strength; Nuclear power plants",,,,,,,,,,,,,,,,"ANSYS 19 Documentation; Asme nog-1, rules for construction of overhead and gantry cranes (2002) American Society of Mechanical Engineers; Us nrc regulatory guide 1. 92 (2006) Combining Modal Responses and Spatial Components in Seismic Response Analysis, Rev. 2; Oh, J., Kwak, J., Jung, K., Lee, J., Structural Integrity Evaluation for Overhead Crane of a Research Reactor (2017) Transactions of the Korean Nuclear Society Autumn Meeting Gyeongju, , Korea, Oct 25-27","Stan, L.-C.; Engineering Sciences Department in Mechanical and Environment, Romania; email: liviustan14@yahoo.com","Vladescu M.Tamas R.Cristea I.","Maritime University of Constanta;Ministry of Research and Innovation;University Politehnica of Bucharest","SPIE","Advanced Topics in Optoelectronics, Microelectronics and Nanotechnologies X 2020","20 August 2020 through 23 August 2020",,166390,0277786X,9781510642713,PSISD,,"English","Proc SPIE Int Soc Opt Eng",Conference Paper,"Final","",Scopus,2-s2.0-85099372813

First, the finite element model of a reinforced concrete slab under near-field explosion is established by ANSYS/LS-DYNA software and compared with the experimental results, which verifies the effectiveness of the ALE (arbitrary Lagrangian-Eulerian) algorithm and the accuracy of the mesh size and material properties. Then, an ""explosive-air-pier""coupling analysis model is constructed using the finite element method, and the damage of the reinforced concrete pier under three types of car bombs is evaluated. Furthermore, a response surface model for the residual bearing capacity of the pier is utilized to calculate the failure probabilities of various damage levels of the pier under the three types of car bombs and to assess the traffic capacity of the bridge after near-field explosion. The established assessment method can be used to predict the probability of bridge structural damage at various levels under different types of car bombs and to provide a reference for exploring a probability-based safety assessment method of post-explosion bridges. © 2020 Jinghui Jiang et al.",,"Bearing capacity;

In order to reduce the serious losses caused by ship-bridge collision incidents, it is necessary to make a rapid estimation of ship collision forces. The simplified analytical formulas can be used to rapidly evaluate the collision force in ship collision accidents, but it is found that the existing simplified formulas are only applicable to bulb structures including small-angle inclined elements and not suitable for large-angle inclined elements which exist in ship-bridge collision. In this paper, the quasi-static crushing simulation of the bulbous structure with small-angle inclined angle elements is carried out, and the applicability of the simplified analytical formula of the intersection unit to the typical structure is verified. By comparing the simplified analytical results of the bow with the quasi-static simulation results and the ratio of the strength reduction factor to the effective crushing distance, it is found that the inclined angle of the inclined element will affect the impact force of the simplified analytical calculation. Then, finite element analysis of the truncated-type intersection structure with different element inclination angles are carried out, and the results show that the existing simplified analytical formula is no longer suitable for the calculation of collision force when the inclined angle is greater than 40°.

To overcomes the abovesaid demerits, In this paper alternate analytical sub-domain model (SDM) for magnetic field computation in Segmented PM switched flux consequent pole machine (SPMSFCPM) with flux bridge and flux barriers accounting boundary and interface conditions, radial magnetized PMs (RM-PMs) and circumferential magnetized PMs (CM-PMs), interaction between stator slots and inner/outer rotor topologies is proposed. Overall field domain is divided into air gap, stator slots and Permanent Magnet (PM) accounting influence of CM/RM-PMs under no-load and on-load conditions. Analytical expression of field domain is obtained by solving magnetic vector potential utilizing Maxwell&#x2019;s equations. Based on the magnetic field computation especially no-load and on-load condition, Magnetic Flux Density (MFD) components, open-circuit flux linkage, mechanical torque and cogging torque are computed utilizing Maxwell Stress Tensor (MST) method. Moreover, developed analytical SDM is validated with globally accepted Finite Element Analysis (FEA) utilizing JMAG Commercial FEA Package v. 18.1 which shows good agreement with accuracy of ~98%. Hence, authors are confident to propose analytical SDM for initial design of SPMSFCPM to suppress computation time and complexity and eliminate requirements of expensive hardware and software tools.

The main purpose of applying this elastomeric device in the base level of structures is Separating of ground vibrations from body of structures. Recent researches have indicated although EB is capable to decrease damages of buildings, especially in irregular buildings despite of torsion cause of increasing roof displacement total collapse of buildings is likely so multi-layer elastomeric bearings braced with steel cable (EBBSC)to control displacement has been introduced. In this study, three different models of EBs have been studied. The first model is Simple multi-layer elastomeric bearings (SEB), the second model is multi-layer elastomeric bearing with vertical steel cable (EBBVSC), and the third model is multi-layer elastomeric bearing with diagonal steel cable (EBBDSC). By applying the cyclic lateral displacement to top level of specimens, their hysteresis load- displacement behavior was achieved under finite element analysis. The results have indicated increasing strength and stiffness for multi-layer elastomeric bearing braced with steel cable. In other hand, the strength and stiffness value in the EBDSC model in compare with the EBVSC model has been increased 28% and 32%, respectively. © 2020 European Association for Structural Dynamics.

Classical procedure based on dynamic measurements able to detect flexibility changes are complemented with data predicting cracks and their evaluating by image processing. The procedure proposes first a damage index, the Stiffness Reduction Factor (SRF), evaluated on the basis of the error between the predictive truss model and the experimental modal model. Then, a nonlinear FEM model is used to determine fatigue cracks in the truss nodes which are compared with the observed ones determined by image processing.

It is employed for a bridge as well, but the application is very limited. The BRB device may also be used as a damper rather than the structural component or the bracing, in which case the device is called a buckling restrained damper (BRD). Yet, such application has not been explored much. There are quite a few bridges designed according to the old seismic design codes in Japan. Their seismic resistance may not be satisfactory for the current seismic design codes. Against this background, the behavior of a steel truss bridge under a large seismic load is investigated by nonlinear dynamic finite element analysis. Some members are indeed found possibly damaged in the earthquake. Retrofitting is therefore needed. To this end, the application of the BRD is tried in the present study. A parametric study on the seismic behavior of the truss bridge with the BRD is conducted by changing the length and the cross-sectional area of the yielding core of the BRD, to this end. The FEA show that the BRD surely improves the seismic performance of the truss bridge and with some BRDs, all the members could stay intact. The points to note for the application of the BRD are also revealed. © 2020 European Association for Structural Dynamics.

The torque density of a vernier machine can be enhanced by increasing the number of slots/pole/phase q, but as q increases the drastic increase in the reactance makes the power factor even worse. Therefore, it is general to choose low q, even if higher torque can be obtained with higher q. In this study, the idea of series compensation is applied to get vernier machine with high q without the low power factor problem. Series compensation is performed by supplying the desired reactive power to the machine from an additional inverter with a floating capacitor. To validate the theoretical analyses, three SPM vernier machines with different q (1 ∼ 3) are designed and then analyzed by using FEM. © 2020 - IOS Press and the authors.

Such bridges possess lower construction and maintenance costs, improved seismic performance, rapid construction procedures, and superior vehicular ride-ability. However, structural analysis of integral abutment bridges is not adequately covered in most bridge design specifications since the majority of the provisions address jointed structures. The purpose of this study is to check whether the current AASHTO LRFD bridge design specifications for live load effect are applicable to integral abutment bridges. To do so, typical single span monolithic bridges are models by finite elements with consideration of different girder spacing, free standing pile lengths and wing- wall lengths. The girder distribution factors for flexure and shear from the finite element investigation are compared with the corresponding formulas in the specifications. The approach utilized by AASHTO to compute the flexural live load effect in the deck slab by considering a unit strip of the slab on rigid supports is checked against the finite element results. In general, findings of the study showed that the AASHTO specifications can be safely used to compute the load effect in girders and slabs of integral abutment bridges. © 2020, Avestia Publishing.

In this paper, the effect of size on punching shear has been quantified for transversely post-Tensioned deck slabs cast between flanges of precast concrete girders. A 1:2 scaled model of the bridge was constructed in the laboratory, and experimental and numerical analyses were carried out. However, in order to apply these results on a real bridge, simply using the geometrical scale factors is not sufficient and a structural size effect has to be taken into account. Since a full-scale experimental study was not possible due to the costs involved, a numerical approach using finite element analysis software package TNO DIANA was used to model both the prototype and the real bridge, and a comparison was made to estimate the effect of size on the bearing capacity. It was found that increasing the transverse prestressing level had a positive effect on the punching shear strength of the deck slab. Furthermore, a lower size effect was observed with higher transverse prestressing levels. It is concluded that if a suitable size factor is used, either numerical or small-scale experimental studies can be reasonably used to investigate existing structures.

Piezoelectric energy harvesters are currently based on two types of external forces, namely pressure load and mechanical oscillation or vibration. A vibration energy harvesting (VEH) is a mechanical oscillation in a piezoelectric energy harvester that harvested electric energy. In the market, there is available energy harvesting device in good electric energy harvesting and very sensitivity. However, the price is too high and the fabrication process is too complex. Furthermore, one of the aimed of the research is to install the energy harvesting device at rotary compressor machine which has noise vibration frequency at 1 kHz to 10 kHz. This paper presented a cavity structure-based flexible piezoelectric vibration energy harvester (FPVEH) based on an IDE circuit for low-frequency vibration applications. A cavity structure (IDE circuity) combine with the flexible circuit (polyimide) and flexible membrane (polyvinylidene fluoride, PVDF) will increase the electric energy harvesting and sensitivity of the device. Therefore, the four designs (Design A to D) are used to investigate the effect of the electrode finger width and the gap between the electrode fingers (to investigate the cavity structure applying in the design). All designs have been characterized by FEA simulation using COMSOL Multiphysics 5.0 and experimental work using a sieve shaker vibration machine. A sieve shaker machine is worked as vibration frequency calibrator. However, the sieve machine can operate at 5 kHz and 7 kHz. Since these two vibration frequencies are in targeted vibration frequency. It is used as vibration frequency calibrator in this experimental work. The results from the FEA simulation and experimental work show the Design D has the highest electric energy harvesting compare to other designs. It has electric energy harvesting at 27.3 V for 1 minutes period. Design D has a wide electrode finger width and the wide gap between electrodes compare to other designs. The vibration frequency was also given the impact to energy harvesting whereby the vibration frequency at 5 kHz has the highest electric energy harvesting compare to vibration frequency at 7 kHz. © 2020 ASTES Publishers.

The device comprises a power electronics submodule which consists of three-phase full-wave bridge rectifier that uses Schottky diodes for AC-DC conversion, followed by a boost converter for DC-DC conversion. The sizing of both the permanent magnets arrays and the coil as well as the location where to place the system on the human body have been adequately set following extensive Finite Element Method (FEM) simulations, in addition of using Matlab and Pspice software tools. Particle Swarm Optimization (PSO) algorithm was used to determine the optimal sizing of the device corresponding to the lowest cost. A wireless accelerometer was placed at different locations of the body of an individual (e.g. lower and upper arms, elbow, ankle, and knee) moving on an indoor treadmill with different speeds to determine the best placement of the device corresponding to the highest power. © 2020 COPYRIGHT SPIE.",,"Biomagnetism; Computer aided software engineering; Electric generators; Electric inverters; Electric rectifiers; Energy harvesting; Infrared detectors; Infrared devices; MATLAB; Particle swarm optimization (PSO); Rectifying circuits; Schottky barrier diodes; AC-DC conversions; Dc-Dc conversion; Finite element method simulation; Full wave bridge rectifiers; Linear generators; Particle swarm optimization algorithm; Pspice software; Wireless accelerometers; DC-DC converters",,,,,,,,,,,,,,,,"(2011) Free Vibration of a Cantilever Beam (Continuous System, , IItg.vlab.co.in, .

Conventional method such as finite element method (FEM) for dynamic coupling analysis of vehicle-bridge system often requires separate iteration of vehicle system and bridge system, and the contact and coupling interactions between them are used as the link for convergence inspection, which is too computationally intensive and time-consuming. In addition, the dynamic response of the vehicle-bridge coupling system obtained by FEM cannot be expressed explicitly, which is not convenient for engineering application. To overcome these drawbacks mentioned above, the backpropagation (BP) neural network technology is proposed to the dynamic coupling analysis of the vehicle-bridge system of long-span suspension bridges. Firstly, the BP neural network was used to approximate the dynamic response of the suspension bridge in the vehicle-bridge coupling system, and the complex finite element analysis results were thus explicitly displayed in the form of a mathematical analytical expression. And then the dynamic response of the suspension bridge under vehicle load was obtained by using a dynamic explicit analysis method. It is shown through a numerical example that, compared with FEM, the proposed method is much more economical to achieve reasonable accuracy when dealing with the dynamic coupling problem of the vehicle-bridge system. Finally, an engineering case involving a detailed finite element model of a long-span suspension bridge with a main span of 1688 m is presented to demonstrate the applicability and efficiency under the premise of ensuring the approximation accuracy, which indicates that the proposed method provides a new approach for dynamic coupling analysis of the vehicle-bridge system of long-span suspension bridges. © 2020 Zuolong Luo et al.",,,,,,,"Chang'an University, CHD: 300102210515; Natural Science Foundation of Shanxi Province: 201901D211121; Fundamental Research Funds for the Central Universities","This work presented herein was supported by Shanxi Province Natural Science Foundation (201901D211121) and the Fundamental Research Funds for the Central Universities, CHD (300102210515).",,,,,,,,,,"Kwon, S.-D., Lee, J.-S., Moon, J.-W., Kim, M.-Y., Dynamic interaction analysis of urban transit maglev vehicle and guideway suspension bridge subjected to gusty wind (2008) Engineering Structures, 30 (12), pp. 3445-3456. , 2-s2.0-55949114410; Xu, Y.L., Li, Q., Wu, D.J., Chen, Z.W., Stress and acceleration analysis of coupled vehicle and long-span bridge systems using the mode superposition method (2010) Engineering Structures, 32 (5), pp. 1356-1368. , 2-s2.0-77950340381; Duan, M., Zhang, S., Wang, X., Dong, F., Mechanical behavior in perfobond rib shear connector with UHPC-steel composite structure with coarse aggregate (2020) Ksce Journal of Civil Engineering, 24 (4), pp. 1255-1267; Jiang, H.P., Wang, J.G., Qian, F., Analysis of vehicle-bridge coupling vibration of long span suspension bridge (2011) Journal of Hefei University of Technology (Natural Science), 34 (1), pp. 114-118; Li, H.Q., Zhao, M.S., Chen, Y.J., Research on vehicle-bridge coupling vibration response of single tower self-anchored suspension bridge (2015) Journal of Chongqing Jiaotong University (Natural Science, 34 (3), pp. 1-6; Ding, N.H., Lin, L.X., Qian, Y.J., Study on vehicle-bridge coupling vibration of double chain suspension bridge (2010) Journal of Lanzhou Jiaotong University, 29 (1), pp. 95-99; Li, X.Z., Liu, D.J., Jin, Z.B., Analysis of vehicle-line-bridge coupling vibration of long-span railway suspension bridge (2010) Steel Structure, 25 (12), pp. 6-12; Liu, Y., Kong, X., Cai, C.S., Driving effects of vehicle-induced vibration on long-span suspension bridges (2017) Structural Control & Health Monitoring, 24 (2). , e1873 2-s2.0-84973144120; Wang, S.Q., Ma, J., Ren, Y.R., Dynamic interaction analysis on wind-train-bridge system of long-span railway suspension bridge (2017) Journal of Railway Science and Engineering, 14 (6), pp. 1243-1250; Ahalt, S.C., Chen, P., Chou, C.-T., Kuttuva, S., Little, T.E., The neural shell: A neural network simulation tool (1992) Engineering Applications of Artificial Intelligence, 5 (3), pp. 183-192. , 2-s2.0-11644299002; Flood, I., Kartam, N., Neural networks in civil engineering.

The results indicated that: The stress at the rib-to-deck welded connection and the rib-to-rib welded connection are the bending stress and the membrane stress, respectively; the stress response of the two welded connection has strong local characteristics; the lateral stress influence line of the two welded connection is relatively short and the length of the lateral stress influence line is greatly affected by the longitudinal ribs; increasing the thickness of the roof and longitudinal ribs can reduce the stress response and improve the stress performance of the heavy lanes. For the two welded details, the fatigue damage increment of the ordinary lane is greater than the heavy lane. The thickened roof and longitudinal ribs at the position of the heavy lane still cannot balance the fatigue damage caused by the heavy truck. Therefore, it is necessary to strictly control the fatigue effect of overloaded vehicles on steel box girders. © 2020 Tech Science Press.

To date, there is no desirable calculation method for analyzing the caps. Based on the fifteen-pile thick cap of mixed passenger and freight railway, the influencing factors on cap bearing capacity were analyzed using finite element method (FEM). The variations of load-bearing capacity and mechanical behavior of thick cap were characterized by introducing rigid angle α. Results indicated that ultimate load-bearing value of the cap increased linearly with the increase of concrete strength grade, and an increasing load-bearing capacity of the reinforcement distributed in the pile diameter range was larger than that of the uniform reinforcement; when the reinforcement ratio was 0.15%, it increased by 9.3%. The cap showed punching failure when α < 45°. The reaction force at each pile top under vertical load was not equal; thereby, the cap was not absolutely rigid. The principal compressive stress trajectories in the concrete were distributed in the range of connecting the pile and the outer edge of the pier, and the effective tensile stresses in the reinforcement were mainly distributed in the diameter range of pile and pile connection, which is in accord with the stress mode of the ordinary spatial truss model. Based on this, a spatial truss model applicable to the design of railway caps is proposed, and a method for calculating reaction force at pile top and formulas for calculating the bearing capacity of strut and tie were presented. The feasibility of the proposed method was also verified by comparison with FEM results. © 2020 Hongmeng Huang et al.",,,,,,,"Fundamental Research Funds for the Central Universities: 31920200059","This work was partly supported by the Fundamental Research Funds for the Central Universities (31920200059).",,,,,,,,,,"Guo, H.L., Jiang, B., Study of pile cap failure type discrimination (2013) Engineering Mechanics, 30 (6), pp. 142-147; Souza, R., Kuchma, D., Park, J.W., Bittencourt, T., Adaptable strut-and-tie model for design and verification of four-pile caps (2009) ACI Structural Journal, 106 (2), pp. 142-150; Huang, X.B., Liu, C.Y., Hou, S., An analysis of the impact exerted on bearing capacity of pier and pile after increasing pile cap height (2018) Shock and Vibration, 2018, p. 9. , 2-s2.0-85049867931; Bloodworth, A.G., Cao, J., Xu, M., Numerical modeling of shear behavior of reinforced concrete pile caps (2012) Journal of Structural Engineering, 138 (6), pp. 708-717. , 2-s2.0-84862539548; Victoria, M., Querin, O.M., Martí, P., Generation of strut-and-tie models by topology design using different material properties in tension and compression (2011) Structural and Multidisciplinary Optimization, 44 (2), pp. 247-258. , 2-s2.0-80052613198; Chetchotisak, P., Teerawong, J., Reliability-based assessment of RC pile cap design methods and proposals for their strength resistance factors (2019) KSCE Journal of Civil Engineering, 23 (8), pp. 3372-3382. , 2-s2.0-85067919594; (2014) Building Code Requirements for Structural Concrete and Commentary, , Farmington Hills, MI, USA American Concrete Institute; (1997) Structural Use of Concrete, Part 1: Code of Practice for Design and Construction, , London, UK British Standards Institution; Abdul-Razzaq, K.S., Farhood, M.A., Design-oriented testing and modeling of reinforced concrete pile caps (2019) KSCE Journal of Civil Engineering, 23 (8), pp. 3509-3524. , 2-s2.0-85067783115; Park, J., Kuchma, D., Souza, R., Strength predictions of pile caps by a strut-and-tie model approach (2008) Canadian Journal of Civil Engineering, 35 (12), pp. 1399-1413. , 2-s2.0-57349133194; Guo, H.L., Spacial strut and tie model for punching load transfer mechanism analysis of pile-cap (2009) Journal of Building Structures, 30 (1), pp. 147-156. , in Chinese; Sun, C.F., Gu, Q., Peng, S.M., Experimental research on steel fiber reinforced concrete two-pile thick caps (2010) Journal of Building Structures, 31 (2), pp. 117-124. , in Chinese; Yun, Y.M., Ramirez, J.A., Strength of concrete struts in three-dimensional strut-tie models (2016) Journal of Structural Engineering, 142 (11). , 2-s2.0-84991721064; Zhou, Y., Dai, G.-L., Parameter study of a new strut-and-tie model for a thick cap with six piles (2016) International Journal of Geomechanics, 16 (1). , 2-s2.0-84954349155; Broms, C.E., Strut-and-tie model for punching failure of column footings and pile caps (2018) ACI Structural Journal, 115 (3), pp. 689-698. , 2-s2.0-85047292499; Yun, Y.M., Kim, B., Ramirez, J.A., Three-dimensional grid strut-and-tie model approach in structural concrete design (2018) Aci Structural Journal, 115 (1), pp. 15-26. , 2-s2.0-85042278849; Group, C., (2016) Canadian Highway Bridge Design Code, , Mississauga, Canada Canadian Standards Association; Communications Press, C., (2018) Specifications for Design of Highway Reinforced Concrete and Prestressed Concrete Bridges and Culverts, , Beijing, China China Communications Press Co.

The initial application and testing of the ATLASS framework for sizing and optimization of new aircraft and structural concepts is discussed along with corresponding improvements and additional functionality. The ATLASS tool is intended to bridge the gap between conceptual and detailed design by implementing higher fidelity automated analysis tools earlier in the design process with applicability to new or novel aircraft configurations. The ATLASS tool includes fully automated modules for Outer Mold Line (OML) generation, internal structural layout, weights and C.G. generation, and Finite Element Model (FEM) generation for loads and structural analysis. All geometric and finite element based models are generated in CATIA and exported to Nastran and Hypersizer for analysis. Analysis and optimization are managed by Isight. An initial study was conducted on a legacy wing configuration to validate the tool and make improvements. Initial results were promising however additional load cases were identified as well as analyses not currently available in Hypersizer to improve weight estimations. These enhancements were integrated then applied to a full aircraft validation study. © 2020, American Institute of Aeronautics and Astronautics Inc, AIAA.

Tensile forces can reduce the punching capacity of the slabs, however, few studies have been carried out to quantify this effect. An experimental, numerical and theoretical investigation has been carried out, in which 5 1.65x1.65x0.12 m slabs have been tested under a point load and different degrees of unidirectional tensile force. Numerical predictions were made with FEA software ABAQUS and, from the theoretical point of view, the Compression Chord Capacity Model (CCCM) was extended to take into account the effect of in-plane tensile forces in the punching strength of the slabs. The experimental results showed that the ultimate punching load decreases linearly with the applied tensile force, and if that tensile force cracks the slabs, such reduction is higher. Results obtained with FEA and CCCM are in agreement with the observations made at the laboratory. © Proceedings of the 2020 Session of the 13th fib International PhD Symposium in Civil Engineering.

Landslides or instability of the slopes is more common in the developing hilly terrain due to unscientific cutting of the toe of rock slope for the construction or widening of roads and/or bridges. The NH-44 in the Jaintia Hills district (Meghalaya, India) connecting Malidor to Sonapur (approx. 30 km), have experienced many landslide events causing huge loss of life and property. The two locations along the NH-44 are considered and different cut sections of slopes were studied to support the further extension of the NH-44. Kinematic analysis reveals that the possible type of failures such as wedge failure, planar failure and toppling failure occurs at the selected locations. The stability assessment of in situ rock slope and different cut slope sections were investigated to determine the effective cut slope.

This micro/nano positioning stage can be used to establish an atomic-force-microscope (AFM) measurement system. A kind of stacked parallel structure is adopted in order to realize a compact and relative symmetrical design. A novel concave-shape bridge amplifier is proposed and utilized in the positioning stage to amplify the stroke of PZT actuators. The amplifier can realize high lateral stiffness, which is an important factor in protecting PZT actuators. The amplifiers are integrated into decoupling mechanisms isolating the top plate motion in two directions. Finite-element analysis (FEA) and Multi-objective genetic algorithm (MOGA) are conducted on the proposed model to optimize and decide the value of the main design variables. The improved performances compared with the initial design are verified by FEA methodology. Results show that the stage can implement 2-DOF decoupled motion in a workspace of 100×100 μm2 with a mechanisim system surface of 100×100mm2.

The two 144-in. diameter discharge aqueducts needed to extend under a 45-ft high causeway embankment. Traditional analysis methods referenced from the American Water Works Association and the United States Bureau of Reclamation sources resulted in very costly trench and backfill methods for this deep pipe cover. A further analysis of external loadings beyond the traditional methods was warranted. To streamline the construction schedule, reduce risk, and reduce construction costs, a two-dimensional finite element analysis was preformed to better predict the deflection of the aqueducts through the causeway. Several simulations were run, along with sensitivity studies, to determine how the pipe zone material properties would impact the deflection and determine the best overall design. Detailed field measurements were taken during construction to assess the accuracy of the assumptions and calculations. This paper presents the traditional and non-Traditional design of these 144-in. diameter pipe sections, with results of actual field conditions. © 2020 American Society of Civil Engineers.",,"Bridges; Causeways; Hydraulic structures; Lakes; Pipelines; Risk assessment; Water levels; Water treatment; American Water Works associations; Bureau of reclamations; Construction costs; Construction schedules; Drought conditions; Field measurement; Sensitivity studies; Two-dimensional finite element analysis; Trenching",,,,,,,,,,,,,,,,"(2012) Steel Pipe-A Guide for Design and Installation-Manual of Water Supply Practices M11, , AWWA (American Water Works Association). 4thEdition.

The breathing mechanism (opening and closing) of the crack is achieved by the application of periodic loading in the transverse direction, in out of plane orientation to the crack and in parallel to the crack orientation of the beam. In this study, damage initiation (crack propagation) is neglected and the research is carried out only for the static crack. Using FEA, the higher order PDEs are converted into a set of coupled ODEs using Galerkin’s weak formulation. The refined mesh is adopted near the crack tip zone and intentionally increases the computational time. In order to reduce the simulation time without losing its accuracy, reduced-order modeling (ROM) approach is implemented in the cracked model to obtain the computationally efficient and equivalent model for the dynamic analysis. With this, we capture more than 99% of the system energy using subspace projection on to the full domain with two proper orthogonal decomposition (POD) modes. Additionally, the effective properties (mass, linear, and nonlinear stiffness, damping, and forcing amplitude) of the nonlinear dynamical system are obtained and incorporated into the Duffing oscillator’s equation of motion, with a cubical stiffness, which is identified from the static deflection of the beam and is solved using state-space approach using Matlab ode45 Algorithm. However, the parametric study is also conducted for different types of forcing amplitudes and frequencies to check the consistency of the ROM with the FEA Abaqus simulation and is in good agreement with its responses. The aperiodic behavior is identified in the linear range and the periodic doubling route to chaos is identified in the nonlinear range qualitatively in this model. © Springer Nature Singapore Pte Ltd 2020.","Breathing crack; Duffng oscillator; Nonlinear dynamics; Proper orthogonal decomposition; Reduced-order modeling",,,,,,,,,,,,,,,,,"Dimarogonas, AD, Vibration of cracked structures: state of art review (1996) Engg Frac Mec, 55 (5), pp. 329-344; Kerschen, G, Worden, K, Vakakis, AF, Golinva, JC, Past, present and future of nonlinear system identification in structural dynamics (2006) Mech System Signal Pro, 20 (3), pp. 505-592; Simon, M, Tomlinson, GR, Use of the Hilbert transform in modal analysis of linear and non-linear structures (1984) J Sound Vibr, 96 (4), pp. 421-436; Coherence, Rauch A, A powerful estimator of nonlinearity, theory and application (1992) Proceedings of 10th international modal analysis conference, pp. 784-795. , San Diego; Irwin, GR, Analysis of stresses and strains near the end of a crack traversing a plate (1957) J Appl Mech, 24, pp. 361-364; Rezaee, M, Hassannejad, R, A new approach to free vibration analysis of a beam with a breathing crack based on mechanical energy balance method (2011) Acta Mech Solida Sin, 24 (2), pp. 185-194; Qian, GL, Gu, SN, Jiang, JS, The dynamic behaviour and crack detection of a beam with a crack (1990) J Sound Vibr, 138, pp. 233-243; Lu, XB, Liu, JK, Lu, ZR, A two-step approach for crack identification in beam (2013) J Sound Vibr, 332, pp. 282-293; Maghsoodi, A, Ghadami, A, Mirdamadin, HR, Multiple-crack damage detection in multi-step beams by a novel local flexibility-based damage index (2013) J Sound Vibr, 332, pp. 294-305; Andreausa, U, Casinib, Vestroni F, Non-linear dynamics of a cracked cantilever beam under harmonic excitation (2007) Int J Non-Lin Mech, 42, pp. 566-575; Bovsunovsky, AP, Suraceb, C, Considerations regarding super harmonic vibrations of a cracked beam and the variation in damping caused by the presence of the crack (2005) J Sound Vibr, 288, pp. 865-886; Bouboulas, AS, Anifantis, NK, Three-dimensional finite element modelling of a vibrating beam with a breathing crack (2013) Arch Appl Mech, 83, pp. 207-223; Franco, E, Dotti, Victor H, Cortínez, Florencia R, Non-linear dynamic response to simple harmonic excitation of a thin-walled beam with a breathing crack (2016) Appl Mathemat Model, 40, pp. 451-467; Buffoni, MR, Telib, H, Iollo, A, Iterative methods for model reduction by domain decomposition (2009) Comp Fluids, 38, pp. 1160-1167; Kulkarni, AS, Pandey, M, Nonlinear dynamic analysis of cracked cantilever beam using reduced order model (2016) Procedia Eng, 144, pp. 1459-1468; Chatterjee, A, An introduction to the proper orthogonal decomposition (2000) Curr Sci, 78 (7), pp. 808-817","Krishnaswamy, V.; MEMS Dynamic Labs, India; email: vikkydesigns@gmail.com","Dutta S.Inan E.Dwivedy S.K.",,"Springer Science and Business Media Deutschland GmbH","13th International Conference on Vibration Problems, ICOVP 2017","29 November 2017 through 2 December 2017",,244639,21954356,9789811556920,,,"English","Lect.

In recent years, tsunamis in Indonesia (2004), Samoa (2009), Chile (2010) and Japan (2011) have caused severe damages to coastal structures including bridges, especially the 2011 Japan tsunami which destroyed over 300 bridges all of a sudden. Therefore, research on the interaction between tsunamis and coastal bridges have drawn attention world-wide in the engineering community. In order to get a better understanding on tsunami-induced destructions, this paper studies the wave loads and structural responses of coastal bridge structures caused by tsunami waves. Firstly, a self-developed numerical wave tank which solves the incompressible Navier-Stokes (N-S) equations is built based on the computational fluid dynamics (CFD) method. Validations on tsunami wave elevations and forces are conducted, the results of which are compared with previous literatures. Secondly, numerical simulations of the interaction between tsunami waves and a box girder bridge are carried out, from which the phenomena of the interaction process and tsunami-induced wave forces are obtained and analyzed. The finite element method (FEM) is used to model the box girder bridge to calculate the structural response of the bridge structure caused by the tsunami wave forces, including the stress distributions and structural displacements. Finally, the effects of two variables of different wave heights and different distances from the bridge bottom to the water surface on the stress at the box girder bridge supports are investigated. Most damages begin with the destruction of the bridge supports, which should be paid attention from an engineering point of view. © 2020 by the International Society of Offshore and Polar Engineers (ISOPE).","Box girder bridge; Bridge destruction; Structural response; Tsunami wave; Wave force","Arctic engineering; Computational fluid dynamics; Navier Stokes equations; Numerical methods; Ocean currents; Steel bridges; Tsunamis; Coastal structures; Computational fluid dynamics methods; Engineering community; Incompressible Navier-Stokes; Interaction process; Numerical wave tanks; Structural displacement; Structural response; Box girder bridges",,,,,"GDME-2018E001; GML2019ZD0604; Applied Basic Research Foundation of Yunnan Province: 2019A1515110738; National Key Research and Development Program of China, NKRDPC: 2018YFC0309601","This work was supported by the National Key Research and Development Program of China (Grant No. 2018YFC0309601), Guangdong Basic and Applied Basic Research Foundation (Grant No. 2019A1515110738), Key Special Project for Introduced Talents Team of Southern Marine Science and Engineering Guangdong Laboratory (Guangzhou) (Grant No. GML2019ZD0604), and the Guangdong Special Fund Program for Economic Development (Marine Economic) (Grant No. GDME-2018E001).",,,,,,,,,,"Bradner, C., Schumacher, T., Cox, D., Higgins, C., Large-scale laboratory measurements of wave forces on highway bridge superstructures (2009) Coastal Engineering 2008-31St International Conference, 5, pp. 3554-3566; Bihs, H., Kamath, A., Chella, M.A., Aggarwal, A., Arntsen, O.A., A new level set numerical wave tank with improved density interpolation for complex wave hydrodynamics (2016) Computers & Fluids, 140, pp. 191-208; Cuomo, G., Shimosako, K.I., Takahashi, S., Wave-in-deck loads on coastal bridges and the role of air (2009) Coastal Engineering, 56 (8), pp. 793-809; Chen, Q., Wang, L., Zhao, H., Hydrodynamic investigation of coastal bridge collapse during hurricane katrina (2009) Journal of Hydraulic Engineering, 135 (3), pp. 175-186; Guler, H.G., Baykal, C., Arikawa, T., Yalciner, A.C., Numerical assessment of tsunami attack on a rubble mound breakwater using openfoam (2018) Applied Ocean Research, 72, pp. 76-79; Greco, M., Colicchio, G., Faltinsen, O.M., Shipping of water on a two-dimensional structure.

However, no systematic study on floating wind turbine foundations is reported for the northern region of South China Sea. To bridge this gap, the current research is performed on the large deformations for bearing capacity of suction caisson in marine clay for southern part of China Sea. In this work, a two-dimensional axisymmetric finite element model (FEM) is established to study the behaviour of suction caisson foundations relative to the marine soft clay under undrained conditions against the pull-out loading by using commercial software ABAQUS/EXPLICIT. The Arbitrary Lagrangian-Eulerian (ALE) technique is adopted to simulate the large deformation of soil caused by pull out of anchors. The studied parameters include uplift loading, load point, cohesion, soil/caisson geometry and initial stress state (Ko). The friction contact interface and contact surfaces are the considered parameters for soil-caisson interaction. The variations in friction angle of soil along the Soil/Caisson surface are measured and present the rising effect on the pull-out capacity. The pull-out force with displacement curve is obtained by the finite element modeling. It is found that the pull-out capacity of suction caisson finite element model shows an increase trend with an increase in friction angle (Ɵ) of soil. Conclusively, the measured parameters are helpful for the effective and reliable geometry design of offshore wind turbine foundations. © 2020 by the International Society of Offshore and Polar Engineers (ISOPE).","Abaqus; Arbitrary Lagrangian-Eulerian; Floating wind turbines; Friction angle; Marine soft clay; Pull-out capacity; Suction caisson","ABAQUS; Arctic engineering; Bearing capacity; Bearings (machine parts); Caissons; Deformation; Foundations; Friction; Offshore oil well production; Offshore structures; Offshore wind turbines; Pressure vessels; Soils; Stress analysis; Arbitrary Lagrangian Eulerian; Axisymmetric finite elements; Floating wind turbines; Friction contact interfaces; Initial stress state; Large deformation finite elements; Suction caisson foundation; Undrained conditions; Finite element method",,,,,"China Scholarship Council, CSC","The authors are thankful to China Scholarship Council (CSC) for providing financial support for Master studies of Malik Faran at Dalian University of Technology, Dalian, China.

In ship and offshore structures, flat-bars, angle-bars, tee-bars and bulb flat-bars are generally used as stiffeners. For these stiffened plates, the effect of stiffeners to increase local bucking strength is well analysed and simple formulas are proposed to represent the effect of stiffeners. On the other hand, U-beam stiffeners are sometimes used in other structures such as bridges. However, they have become used also in ship and offshore structures recently. For example, U-beam stiffeners are now used in hatch covers of bulk carriers. In the present paper, characteristics of U-beam stiffeners are examined from the viewpoint of local buckling of stiffened plates based on the results of numerical calculation applying nonlinear FEM. © 2020 by the International Society of Offshore and Polar Engineers (ISOPE).","Simple formulas; Stiffened plates with U-beam stiffeners, Local buckling strength; Ultimate strength","Arctic engineering; Buckling; Offshore oil well production; Offshore structures; Ships; Buckling/plastic collapse; Bulk carrier; Local bucking; Local buckling; Nonlinear FEM; Numerical calculation; Stiffened panel; Stiffened plate; Plates (structural components)",,,,,,,,,,,,,,,,"Fujikubo, M., Yao, T., Elastic Local Buckling Strength of Stiffened Plate Considering Plate/Stiffener Interaction and Welding Residual Stress (1999) Marine Structures, 12, pp. 543-564; Kyokai, N.K., Rules for Survey and Construction of Steel Ships (2017) Part CSR-B & T Common Structural Rules for Bulk Carriers and Oil Tankers, pp. 450-451; Yao, T., Brunner E., Cho, S-.R., Choo, Y.S., Czujko, J., Estefen,, S.F., Goldo, J.M., Hess, P.E., Naar, H., Pu, Y., Rigo, P. and Wan, Z.Q.

In 1989, the San Francisco earthquake significantly damaged the San Francisco–Oakland Bay Bridge and caused serious disaster. It also caused serious damage to other bridges that affected the rescue efforts. Meanwhile, many of the old bridges in the world were built more than 30 years ago and are required to be strengthened to resist earthquakes and to extend their service life. In this study, the Abaqus finite element program is employed to analyze the nonlinear behavior of bridge piers under soil and structure interaction. The concrete pier and concrete pile are modeled by the concrete damage plasticity model. The reinforcing steel is modeled by the elastic-perfectly plastic model. The soil is also modeled by an elastic-perfectly plastic model with the Mohr-Coulomb yield criterion. In addition, infinite elements for soil are used to simulate the infinite domain of earth. Finally, fiber reinforced plastics (FRP) are modeled with the nonlinear stress-strain relations suggested by Hahn and Tsai and with the Tsai-Wu failure criterion. For the numerical analyses, nonlinear finite element analysis of RC bridge piers strengthened by FRP under the soil-pile interaction are carried out. Parametric studies are performed to study the effect of laminate layup of FRP, strengthening area of FRP, mono pile, group piles and scour depth of piles on the ultimate strength and failure behavior of bridge pier system and important conclusions are given. © 2020 by the International Society of Offshore and Polar Engineers (ISOPE).","Bridge structure; Composite material; Pushover; Seismic force","ABAQUS; Arctic engineering; Bridge piers; Concretes; Earthquakes; Fiber reinforced plastics; Finite element method; Nonlinear analysis; Offshore oil well production; Pile foundations; Piles; Safety engineering; Scour; Soils; Stress-strain curves; Toll bridges; Concrete damage plasticity models; Elastic perfectly plastic; Fiber reinforced plastic(FRP); Mohr Coulomb yield criterion; Non-linear finite-element analysis; Non-linear stress-strain; Soil and structure interactions; Tsai-Wu failure criterion; Failure (mechanical)",,,,,,,,,,,,,,,,"Corporation, D.S., (2019) SIMULIA Abaqus Analysis User’s Manuals, , Theory Manuals and Example Problems Manuals, France; Hahn, H.T., Tsai, S.W., Nonlinear elastic behavior of unidirectional composite laminae (1973) Journal of Composite Materials, 7 (1), pp. 102-118; Hu, H-T, Kuo, C-H, Chen, P-J, Liu, K-Y, Wu, K-M (2019). “Nonlinear finite element analysis of bridge pier under static and dynamic loading, the 29th International Ocean and Polar Engineering Conference, Honolulu, Hawaii, USA; Huang, W.-H., (2013) Influence of Riverbed Scour on Seismic Performance of Bridges, , M.S.

This facility at Queen’s University in Kingston, Ontario, is the first of its kind in Canada. ROLLS can apply cyclic loading in a controlled laboratory environment, under realistic highway scale ‘rolling wheel loads’, in lieu of the conventional‘pulsating stationary loads’. It has two half-axles of a large tandem, each comprising a dual 1140 mm diameter air-inflated tires spaced at either 1.2 or 2.4 m. Each half-axle can apply up to 125 kN, representing the heaviest half-axle load of the CL-625 design truck of the Canadian Highway Bridge Design Code (CHBDC). The maximum travel range and speed are 14.9 m and 6 m/s, respectively. A case study involving analysis of a bridge with eight adjacent B900 box girders of 27.6mspan was carried out prior to experimentally testing one of the girders using ROLLS. Load distribution analyses were conducted using both (i) a finite element model of the full bridge under various CL-625 truck loading configurations and (ii) the CHBDC load distribution method, and both agreed well. Scaling analysis of the girder load share was then conducted to account for shortening it to 16 m to fit in the laboratory, resulting in two-115 kN ROLLS design loads, 1.2 m apart. Multiple passes were conducted at various loads of 40%–100% of the design load, at speeds of 1–5 m/s to examine the machine and girder behaviours. It was found that the applied load fluctuates by less than 10% of full capacity and a 0.13 s/cycle time lag occurs. The measured girder deflection and elastic strains were 11%–20% lower than predicted theoretically. With the two half-axles assembly spaced at 1.2 m, the apparatus has the ability to complete three million cycles in approximately 4.5 months if ran continuously at 5 m/s. © 2020, Canadian Science Publishing.

Loading consisted, alternately, in a preloading of 10 N and 20 N of the sutures. The footprint coverage of the standard double-row, TOE, and PASTA techniques was estimated to represent 19%, 30%, and 35%, respectively, of the repair area. The average contact pressures followed an opposite trend, i.e., the largest was estimated for the standard double-row technique, whereas the lowest was estimated for the PASTA technique.

It is based on a multilevel modeling approach, where three different models are combined using simple linear elastic beam models for the reinforcement design, low fidelity nonlinear finite element models to compute the deformation at the full structural scale and finally high fidelity nonlinear finite element models to compute the crack widths at critical hot spots of the structure. The uncertainty of structural parameters is quantified by means of polymorphic uncertainty models combining stochastic and non-stochastic approaches. The multilevel approach is applied to the safety assessment and the crack widths prediction of a reinforced concrete beam structure.

The main aim of the paper is to assess if the arch rib inclination may be an effective strategy to enhance the structural integrity of the bridge structure against out-of-plane buckling mechanisms. The nonlinear behavior of the structure is investigated throughout an advanced 3D finite element model, which accurately reproduces nonlinear sources involved in the cable system and structural elements. An analysis that combines results obtained by traditional elastic buckling analysis and incremental nonlinear elastic analysis is employed to properly evaluate the maximum capacity of the structure. Comparisons between bridge structures with inclined and vertical ribs configurations are proposed focusing attention on both structural and economic aspects. Results show that rib inclination provides several structural benefits to the bridge while reducing overall construction costs. © 2020 Elsevier B.V..

The feasibility of this study was achieved by analyse and develop eighteen models twice using ABAQUS software; six different deck stiffness and three different girder profile. A nonlinear static finite element analysis was performed on the previous models. The results show that the maximum stress found at maximum deck stiffness and the maximum cable stress found at maximum girder cross section. Also, the deflection decreased dramatically with the increase of deck stiffness. Therefore, the relationship between the vertical displacement and deck stiffness is inverse. Referring to the data obtained and collected from these analytical models the concrete deck slab with 50 MPa grade is the optimum grade in terms of strength and serviceability requirements. © 2020 The Authors.","Bridges; Cable spacing; Cable-Stayed; Deck stiffness; Degradation; Optimization; Vertical deformation",,,,,,,,,,,,,,,,,"(2007) AASHTO LRFD Bridge Design Specifications, , American Association of State Highway and Transportation Officials; (2017) Documentation: ABAQUS Theory Manual, , ABAQUS Elements; Bannazadeh, B., Zomorodian, Z.S., Maghareh, M.R., A Study on Cable-Stayed Bridges (2012) Applied Mechanics and Materials, 193, pp. 1113-1118. , Trans Tech Publications; Bridge, L.M., Bridge, R.U., CABLE-STAYED BRIDGES of PRESTRESSED CONCRETE (1973) PCI Journal, 69; Mander, J.B., Priestley, M.J., Park, R., Theoretical stress-strain model for confined concrete (1988) Journal of Structural Engineering, 114 (8), pp. 1804-1826; Janjic, D., Pircher, M., Pircher, H., Optimization of cable tensioning in cable-stayed bridges (2003) Journal of Bridge Engineering, 8 (3), pp. 131-137; Leonhardt, F., Cable stayed bridges with prestressed concrete (1987) PCI Journal, 32 (5), pp. 52-80; Al-Rousan, R., Haddad, R.H., Al Hijaj, M.A., Optimization of the economic practicability of fiber-reinforced polymer (FRP) cable-stayed bridge decks (2014) Bridge Structures, 10 (4), pp. 129-143; Virlogeux, M., Recent evolution of cable-stayed bridges (1999) Engineering Structures, 21 (8), pp. 737-755; Tsai, W.T., Uniaxial compressional stress-strain relation of concrete (1988) Journal of Structural Engineering, 114 (9), pp. 2133-2136; Wang, P.H., Tseng, T.C., Yang, C.G., Initial shape of cable-stayed bridges (1993) Journal of Computers Structures, 46, pp. 1095-1106","Al-Rousan, R.; Department of Civil Engineering, Jordan; email: rzalrousan@just.edu.jo","Lagaros N.D.Abdalla K.M.Marano G.C.Phocas M.C.Al Rousan R.",,"Elsevier B.V.","1st International Conference on Optimization-Driven Architectural Design, OPTARCH 2019","5 November 2019 through 7 November 2019",,142428,23519789,,,,"English","Procedia Manuf.",Conference Paper,"Final","All Open Access, Gold",Scopus,2-s2.0-85088015113

Firstly, in order to improve the efficiency of model updating, the high-precision RBF is used as the surrogate model to replace the original finite element model. Secondly, the MODE algorithm is used to solve the global optimization of multiple objective functions, and the reasonable solution is selected from the Pareto optimal solution set to improve the model updating effect. Finally, the numerical simply supported beam calculation is used. The results show that the error between the 'measured response value' and the theoretical response value of the updated finite element model is significantly reduced, and the parameter values of the updated finite element model are close to those of the 'actual bridge model', which shows that the proposed method can better realize the correction of the bridge finite element model. © 2020 IEEE.","Bridge engineering; Finite element model updating; Multi-objective differential evolution; Radial basis function","Big data; Efficiency; Evolutionary algorithms; Global optimization; Pareto principle; Radial basis function networks; Smart city; Finite-element model updating; Model updating; Multi-objective differential evolutions; Multiple objective functions; Pareto optimal solutions; Radial Basis Function(RBF); Simply supported beams; Surrogate model; Finite element method",,,,,,,,,,,,,,,,"Zong, Z., Xia, Z., Finite element model updating method of bridge combined modal flexibility and static displacement (2008) China Journal of Highway and Transport, 21, pp. 43-49; Yuan, A., Dai, H., Sun, D., Finite element model updating for a cable-stayed bridge considering the boundary condition constraint and parameter sensitivity (2010) JOURNAL OF BASIC SCIENCE AND ENGNEERING, 18, pp. 900-909; Ren, W., Chen, H., Response-surface based on finite element model updating of bridge structures (2008) China Civil Engineering Journal, 41, pp. 73-78; Zong, Z., Gao, M., Xia, Z., Finite element model validation of the continuous rigid frame bridge based on structural health monitoring part i: Fe modal updating based on the response surface method (2011) China CIVIL ENGINEERING JOURNAL, pp. 90-98; Wei, J., Ren, W., Static and dynamic bridge finite element model updating based on response surface method (2015) Journal of Highway and Transportation Research and Development, 32, pp. 68-73; Batmaz, I., Tunali, S., Small response surface designs for metamodel estimation (2003) European Journal of Operational Research, 145, pp. 455-470; Baruch, M., Optimization procedure to correct stiffness and flexibility matrices using vibration tests (1978) Aiaa Journal, 16, pp. 1208-1210; Fei, Q., Zhang, L., Finite element model updating using radial basis function neural network (2004) Journal of Nanjing University of Aeronautics & Astronautics, 36, pp. 748-752; Zhou, L., Jinping, O.U., Finite element model updating of long-span cable-stayed bridge based on the response surface method of radial basis function (2012) China Railway Science, 33, pp. 8-15; Shabbir, F., Omenzetter, P., Particle swarm optimization with sequential niche technique for dynamic finite element model updating (2015) Computer-Aided Civil and Infrastructure Engineering, 30, pp. 359-375","Zhao, Y.; School of Highway, China; email: zhaoypl995@sina.com",,,"Institute of Electrical and Electronics Engineers Inc.","2020 International Conference on Intelligent Transportation, Big Data and Smart City, ICITBS 2020","11 January 2020 through 12 January 2020",,160946,,9781728166971,,,"English","Proc. - Int.

According to response surface models, the multi-objective optimization problem is transformed into a single-objective optimization problem by weight method, and the optimal solutions of parameters under different weights are found. The results show that the response surface model simulated by the response surface method has a high degree of fitting with the results of the finite element method.

The results show that under the longitudinal and transverse sunshine temperature, the concrete of the pier is mainly subjected to compression, and the maximum stress generally appears at the corners. Increasing the arc chamfer can effectively reduce the stress concentration phenomenon, the displacement of the pier top caused by the longitudinal sunshine temperature is small, and caused by the transverse sunshine temperature is large. under the load of cold wave, the outer wall of the pier is tensile stress and the inner is compressive stress, the maximum tensile stress at the outer wall exceeding the allowable tensile stress, in order to prevent concrete cracking, it is recommended to arrange sufficient horizontal and vertical steel bars on the outside.

The American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications for Highway Bridges and AASHTO LRFD Bridge Design Specifications procedures do not account for the presence of railings when evaluating the load-carrying capacity of highway bridges. This paper presents a parametric study using 3D finite element analysis to investigate the influence of railing stiffness on one-span, two-lane steel girder bridges. Railings of different sizes were placed on one or both sides of the bridge deck, in combination with various span lengths and girders spacing. AASHTO HS20 design trucks were placed longitudinally and transversally in order to produce maximum longitudinal bending moments in the steel girders. The wheel load distribution obtained from finite element analysis at the critical section of each bridge were compared with the AASHTO procedures and with reference cases for bridges without railing. This study confirmed that the presence of concrete railings modeled and built integrally with the deck tends to stiffen the bridge superstructure. Further, the study quantified the effect of railing in increasing the load-carrying capacity of steel bridges. The results of this research will therefore assist structural engineers in better designing new steel girder bridges and/or evaluating more precisely the load-carrying capacity of existing bridges with railings of different sizes. Bridge engineers can consider adding or stiffening railings/parapets as a practical method for strengthening existing steel girder bridges. © 2020 Int.

Although, such approach provides significant time and labour savings, it may lead to dangerous overestimation of the load carrying capacity of evaluated structures. Theoretical bases for this effect are being explained and illustrated by means of a comparison of two essentially different approaches to analysis of masonry arch bridges. Both of them are using Finite Element Method, however each with different material model for the arch barrel. One of them is based on an advanced nonlinear non-tensile-resistant constitutive model most properly representing masonry, while the other one is a linear-elastic model with unlimited compressive as well as tensile strength. In a parametric study of bridges with various geometries and mechanical properties all differences depending on the applied material model in the structures’ response to typical loading scenario are presented. Clear measures enabling numerical comparison of the approaches are given. Some diagrams are provided to describe and explain effectively the essence and causes of the appearing differences (including distribution of internal forces or cracking development) originating from the chosen material modelling techniques. General conclusions coming from the study are drawn. © Springer Nature Switzerland AG 2020.","Masonry arch bridge; Nonlinear analysis; Numerical modelling; The ultimate load",,,,,,,,,,,,,,,,,"(1995) Recommendations for the Assessment of the Load Carrying Capacity of Existing Masonry and Mass-Concrete Arch Bridges; Costa, C., Kamiński, T., Comparison of various modelling techniques applied in analysis of masonry arch bridges (2016) 8Th International Conference on Arch Bridges, pp. 835-842. , Wrocław, Poland, 5–7 October 2016, pp; Hojdys, Ł., Kamiński, T., Krajewski, P., Experimental and numerical simulations of collapse of masonry arches (2013) 7Th International Conference on Arch Bridges, pp. 715-722. , Trogir-Split, Croatia, pp; Kamiński, T., Tests to collapse of masonry arch bridges simulated by means of FEM (2010) 5Th International Conference on Bridge Maintenance.

Events were co-organised by members of a student scientific group “Young Bridge Builders” at Wrocław University of Science and Technology in Poland. The first initiative has been held as a part of the program “Bridges” organised by “Wrocław – European Capital of Culture 2016”. Project concerned design, construction and transport of a model of the Zwierzyniecki Bridge (steel arch bridge – one of the oldest and the most charming bridges in Wrocław) built in scale 1:4. Whole process of realization starting from concept, through calculations, choice of materials, construction and transport to the final destination will be described. The second event “Students’ Steel Bridge Competition” is being organised for seven yearsat Wrocław University of Science and Technology. The main topic of the 5th edition were “Arch Bridges”. The main competition principle is to be as much as possible similar to bridges investment process – from design, through construction, to proof-load tests. Five person students’ teams should calculate in advanced FEM programs, then built and test projects of 2.5 m long arch bridge models. In conclusion of this paper scientific benefits of organisation and participation in the university initiatives will be presented, as well as advantages of alternative methods used in young’s engineer education. © Springer Nature Switzerland AG 2020.","Arch bridges models; Construction; Designing; Scientific benefits; Testing; University initiatives",,,,,,,,,,,,,,,,,"Hawryszków, P., Galik, K., “Most Zwierzyniecki Kopiuj – Wklej” – projekt zrealizowany w ramach Europejskiej Stolicy Kultury (2018) Mosty, 2, pp. 76-78; Hawryszków, P., Galik, K., (2016) Projektuj – Buduj – Testuj, Czyli Studencki Konkurs Mostów Stalowych 2016, , Obiekty inżynierskie, mosty – wiadukty – tunele (4); Hawryszków, P., Czaplewski, B., Galik, K., Górniak, T., Marchel, A., Matyl, M., Przygoda, A., Teichgraeber, M., Konkursy mostowe dla młodzieży akademickiej – walory poznawcze, dydaktyczne i naukowe (2017) VIII Ogólnopolska Konferencja Mostowców Inframost 2017, Wisła, pp. 81-92. , pp","Hawryszków, P.; Faculty of Civil Engineering, 27 Wybrzeże Wyspiańskiego St., Poland; email: pawel.hawryszkow@pwr.edu.pl",,,"Springer",,,,,2522560X,,,,"English","Structur.

They are able to meet the design and safety requirements as for traditional bridges more rapidly and at a lower cost. Seismic excitations are completely different in comparison to the static and dynamic loads. Therefore, during the design of soil-steel bridges on the seismic areas, the appropriate structural solutions should be found to avoid an increase of the internal forces acting in such bridges. The paper presents the results of the numerical study of the soil-steel arch bridge under seismic excitation applying four models (1–4). The soil-steel arch bridge with span of 17.67 m and height of 6.05 m was selected for the numerical analysis. Calculations were conducted using the DIANA program based on a finite element method. The non-linear models with seismic excitation of El Centro form 1940 and Time-History analysis were applied. The conclusions from the study can be useful in making a decision regarding the design of the steel-soil bridges located in seismic zones. © Springer Nature Switzerland AG 2020.","Boundary condition; Corrugated plate; FEM analysis; Seismic excitation; Soil-steel bridge",,,,,,,,,,,,,,,,,"Maleska, T., Beben, D., Study on soil-steel bridge response during backfilling (2018) 9Th International Conference on Bridge Maintenance, Safety and Management, Melbourne, pp. 548-554. , Powers, N., Frangopol, D.M., Al-Mahaidi, R., Caprani, C.

The restoration and conservation of this type of structures has become one of the main challenges of bridge engineering. As a first step, any intervention strategy requires an early stage consisting in the assessment of the structural safety (in the actual condition) of the masonry bridge. Only after that stage is performed, it is possible to design, if required, optimal repair interventions to bring the bridge to adequate safety level. In the first part of this paper, the seismic vulnerability assessment of a slender multi-span masonry arch bridge is presented. Results show that it is required to increase the flexural capacity of the structure. In the second part, an innovative intervention technique intended to increase the capacity of masonry arches is discussed. The proposed intervention technique consists on applying a layer of steel fiber reinforced mortar (SFRM) on the arch intrados. The behavior of a masonry arch strengthened with this technique is discussed by means of experimental and analytical results. © Springer Nature Switzerland AG 2020.","Composites; Finite element analysis; Masonry bridges; Retrofitting; Seismic assessment",,,,,,,,,,,,,,,,,"Sarhosis, V., de Santis, S., de Felice, G., A review of experimental investigations and assessment methods for masonry arch bridges (2016) Struct.

A 500 μm long acoustic cavity, based on a four-hole SCF, is designed, simulated and evaluated by using the finite element method. The cavity is acoustically excited in the frequency range of 50 - 56 MHz and the induced displacements are integrated along the fibre. A standard single mode fibre is simulated under the same conditions for comparison. The results show strong Lamb acoustic modes oscillating in the silica bridges and overlapping in the SCF core at the resonance of 52.84 MHz. The induced displacement achieves a maximum in the core centre decaying to an almost null value in the cladding. The acoustic wave concentration in the SCF core is 13 times higher compared to the standard fibre, indicating a promising solution to overcome the frequency limitation of the current all-fibre acousto-optic devices. The modulation efficiency is increased without reducing the fibre diameter, making the devices more stable, fast and suitable to modulate all-fibre lasers. © COPYRIGHT SPIE.

In order to investigate the propagation behavior of distortion-induced fatigue cracks at web gaps in steel bridges, finite element models based on eXtended Finite Element Method (XFEM) were built to simulate the entire welding process of the vertical stiffener web gaps. The results of the welding process show that significant transverse welding residual tensile stress exists at the stiffener-to-web weld toes, and the peak value is close to the yield strength. Numerical fracture mechanical analysis results indicate that the initial crack angle has great influence on the crack propagation mode. Typical fatigue cracks at the vertical stiffener web gap are Mode I leading mixed mode cracks of Modes I, II and III. Dynamic crack propagation considering welding residual stress has faster propagation rate and is consistent with full-scale fatigue test results. The influence of welding residual stress cannot be neglected for analysis and assessment of distortion-induced fatigue cracks in steel bridges.

In this study, the formula for predicting in-plane global elastic buckling load of the SAWWO under pure axial compression has been initially derived, and it is validated by finite element analysis (FEA). By not considering local buckling for all components of the arch through limiting the slenderness of the chords and the height-to-thickness ratio of the webs, the normalized slenderness of the arch under pure axial compression, and the stability coefficient of the arch are introduced to account for the overall buckling and cross-sectional plasticity. Accordingly, a φ-λn curve of the arch for predicting its load resistance is then proposed. Moreover, the in-plane instability mechanisms, failure modes and load resistance of the arch under a uniform radial load, a full-span uniform vertical load (FSUVL), a half-span uniform vertical load (HFUVL) and their combined actions have been investigated respectively. As a result, a general strength design method is therefore established based on the research findings.

In this paper, finite element analysis of an actual composite bridge was conducted to study the transverse moment distribution of concrete slabs subjected to a linear uniform load. The impacts of the spacing of headed studs at the steel-concrete interface were also investigated. Then a frame model constrained by springs was introduced to explore the mechanism of the transverse moment distribution of concrete slabs. The results show that the transverse flexural stiffness of steel girders, mainly determined by the layout of crossbeams and the vertical stiffeners, is the major influencing factor on the moment distribution. The spacing of headed studs also slightly affects the moment distribution since the connectors could change the rotational constraints on slabs provided by steel girders. The comparison between FEA results and the frame model method proves that the proposed frame model could obtain accurate results for predicting the transverse moment distribution.

Produced by casting, the deck can be of any shape without welding and expected to have little possibility of fatigue crack. The deck would be light also, about a half of the RC deck slab, so that it could enhance the seismic resistance of a bridge. The deck was designed, following the Japanese design specifications for steel highway bridges. To that end, the design analysis was done by 3-D FEM to take local stress into account, making the maximum stress smaller than the allowable value. The first challenge in this research is to produce a ductile cast-iron deck with uniform material property: difficulty arises from the fact that it is not only quite large but also thin relative to the width. Through computational simulations and actual casting trials, the ductile cast-iron deck panel has been produced successfully. To investigate its structural behavior, the panel was loaded statically at its center. Ductile structural behavior has been confirmed. Fatigue test was then carried out. No fatigue cracks occurred even when the number of the loading cycles reached 10,000,000.

Numerous researchers highlighted and studied the advantages and favorable properties of the trapezoidally corrugated web girders in the past. However, there are only a limited number of available design proposals for the resistance calculation of trapezoidally corrugated web girders. The current research focuses on the authors' contribution to recover this lack of information and to improve the economic design of corrugated web girders. In frame of the research activity standard conform design procedures are developed providing both analytical resistance models and proposals for FEM based design approaches for the design of corrugated web girders. The design proposals are developed based on comprehensive experimental, analytical and numerical studies.

A structural type of curved continuous girder bridge with a double composite section in the negative moment region is proposed, consisting of a steel tub with a concrete top slab and a concrete bottom slab, which are connected to each other by shear connectors to carry load together. In order to investigate the mechanical properties of this structure, a parametric analysis was carried out on the effect of concrete bottom slab dimension and connector arrangement. Under the action of eccentric load, the longitudinal distortion stress and the distortion angle of the curved continuous double composite girder bridge was compared. Results show that the double composite action can reduce the longitudinal distortion stress and the distortion angle of the section, and only vertical studs are needed.

It may cause the failure of a bridge in various ways such as unseating of the deck, pier failure, bearing failure, and local damage to decks and girders. The damage level of bridge also depends on the distance of the bridge from the fault rupture because the properties of ground motion change with distance from the fault rupture. This paper focuses on pounding probability of a three-span highway bridge subjected to three different types of ground motions, namely, near-field ground motion with pulse, near-field ground motion without pulse, and far-field ground motion along the longitudinal direction of the bridge. Finite element analysis of the bridge was performed in OpenSees considering the nonlinear behavior of piers and bearings. Energy dissipation during pounding of decks was also considered. Incremental dynamic analysis (IDA) was performed to obtain the level of earthquake shaking (i.e., peak ground acceleration (PGA)) required for pounding between adjacent decks. Based on the IDA, fragility analysis was performed to obtain the pounding probability of decks. At a particular PGA level, it was found that far-field ground motions resulted in higher pounding probability as compared to near-field ground motions. When gap size was small, pounding probability for near-field ground motion with pulse was found to be smaller than that of near-field ground motion without pulse. However, when the gap size was large, near-field ground motion with pulse caused higher pounding probability as compared to near-field ground motions without pulse. © 2020, Springer Nature Singapore Pte Ltd.","Fragility curves; Incremental dynamic analysis (IDA); Near-Field and Far-Field ground motions; Pounding","Earthquakes; Energy dissipation; Faulting; Piers; Earthquake shaking; Far-field ground motion; Incremental dynamic analysis; Longitudinal direction; Near field ground motion; Peak ground acceleration; Relative displacement; Simply supported bridge; Probability",,,,,,,,,,,,,,,,"Billah, M., Alam, S., Bhuiyan, R., Fragility analysis of retrofitted multi-column bridge bent subjected to near-fault and far-field ground motion (2013) J Bridge Eng, 18 (10), pp. 992-1004; Brown, A.S., Saiidi, M.S., (2008), Investigation of near-fault vs. far field ground motion effects on a substandard bridge bent.

This wind tunnel test is often cumbersome and expensive and therefore should only be used for the final design stage. In this study, consideration is primarily focused on numerically determining the fluttering effect. The critical flutter wind speed of a bridge superstructure is computed through the use of computational fluid dynamics in conjunction with finite element analysis of the full bridge model. Upon evaluation of discrete vortex method, flutter derivatives are determined which are then used to describe the full dynamic equation. The quadratic complex eigenvalue solution of this response equation is solved to find the critical wind speed of the given cross section. This critical wind speed allows the engineer to have a preliminary justification of whether the chosen shape is within a reasonable aeroelastic response given wind design speeds at the project site. This is especially important because, for large bridge projects, the industry is trending towards design-build projects where it is beneficial to fast-track the design process. This study is focused on the Abraham Lincoln cable stay bridge in Louisville, Kentucky, with comparison to wind tunnel results done on the structure. © 2020 American Society of Civil Engineers.",,"Bridges; Computational fluid dynamics; Eigenvalues and eigenfunctions; Flutter (aerodynamics); Forestry; Speed; Wind; Wind tunnels; Aeroelastic response; Bridge superstructure; Complex eigenvalues; Critical structures; Critical wind speed; Design-build projects; Discrete vortex method; Flutter derivatives; Structural design",,,,,,,,,,,,,,,,"(2017) AASHTO LRFD Bridge Design Specifications, U.SbookCustomary Units, , 8th Edition.

The pavement force found from the vehicle response and road roughness has been given as input in 3-D FEM model created in CSI Bridge. Fatigue life of the bridge component at the critical location has been found out using Miner approach and the stress time history from coupled and uncoupled schemes has been used for comparison purpose.

Under the current logging road specification, temporary bridges are built with log stringer for temporary usage and are removed or left to deteriorate at the end of the use period. This situation leads to a problem to whoever needs to cross the stream for official or personal purposes. This road is customarily used only for a short period with a prolonged usage cycle, and this leads the management to close these roads whenever there are no logging activities. Most of the time upon completion of logging activities, these temporary bridges are not maintained and will deteriorate and collapse due to the high velocity of water flow, erosion, and sedimentation. Modular and mobile concepts of the bridge are recommended for easy transportation, installation, and removal for reuse at multiple sites. This modular mobile forest bridge consists of the segmented timber beams which are joined by aluminium connector. Therefore the critical part of this structure is at the joint where failure might occur when the loading is applied. Five connector designs had been recognised to join the segmented timber beams. Finite element analysis (FEA) was used under static stress analysis with five different load cases to carry out the simulation. Modulus of resilience was calculated to determine the capability of the material to store energy under the deflection. Deflection analysis and volume of connectors were also analysed for result comparison. © Springer Nature Singapore Pte Ltd 2020.","Aluminium; FEA; Girder; Segmented beam; Static stress; Timber","Aluminum; Beams and girders; Computer aided engineering; Flow of water; Logging (forestry); Roads and streets; Stress analysis; Stringers; Temporary bridges; Timber; Wooden beams and girders; Connector design; Deflection analysis; Forest harvesting; High velocity; Result comparison; Segmented beam; Static stress; Static stress analysis; Finite element method",,,,,,,,,,,,,,,,"Brinker, R.W., Taylor, S.E., (1997) Portable Bridges for Forest Road Stream Crossings.

Finite element is most often used method to analyze real bridges; we have various number of FE software available; Midas is one of its kind used to accurately simulate the real bridge. A very less effort has been done till now to analyze the tied-arch bridges for IRC loading conditions; this paper investigates the stability of 200 m span bridge under IRC loading cases. Efforts are made to find out the influence of straight, inclined, and network hanger arrangements on the structural behavior of bridge and also to justify the results; thickness of deck slab is varied for the above hanger arrangements. Objective of the work was to determine the most optimal arrangement of hangers along the deck slab for a road bridge, consisting of two steel arches using finite element analysis method. Nonlinear static analytical method was used for the analysis by using an FEM software Midas Civil. Validation of software for AASTO LRFD vehicle was done. 3D models of single span 200 m slab tied-arch bridges for different hanger arrangements have been done to determine maximum displacement, bending moment, and reactions. Deck slab was also varied for the different types of hanger arrangements that determine minimum displacement, minimum bending moment, and maximum support reaction to find the best combination of deck slab thickness and hanger arrangement. © Springer Nature Singapore Pte Ltd 2020.","Arch rib; Hangers; Midas civil; Nonlinear static analytical method; Tied-arch bridges","Arch bridges; Arches; Bending moments; Bridge decks; Finite element method; Arch rib; Hangers; Midas civil; Nonlinear statics; Tied arch bridges; Loading",,,,,,,,,,,,,,,,"https://simple.wikipedia.org/wiki/Arch_bridge, Wikipedia; https://en.wikipedia.org/wiki/Tied-arch_bridge, Wikipedia; Finke, J.E., (2016) Static and Dynamic Characterization of Tied Arch Bridges, , Missouri University of Science and Technology; Briseghella, B., Gallino, N., Gentile, C., Zordan, T., Finite element modelling of a tied arch bridge from operational modal analysis (2007) Proc. 5Th International Conference on Arch Bridges; Midas User Manual, , https://en.midasuser.com/product/civil_overview.asp; Smit, T.J.M., Design and construction of a railway arch bridge with a network hanger arrangement (2013) Journal of Civil Engineering Research 2013, p. 214. , Delft University of technology, pg 1; Namin, A.A., (2012) Structural Evaluation of Tiedarch and Truss Bridges Subjected to Wind and Traffic Loading, , Doctoral dissertation, Eastern Mediterranean University (EMU)); Rane, K., Structural evaluation of bow string and network arch bridge with different design parameters and bracings (2018) IJCIET, 9, pp. 671-689. , March; Koshi, K., Laju, K., Performance comparison of through arch bridge at different arch position (2016) IJSER, 7 (9). , September; Vlad, M., Kollo, G., Marusceac, V., A modern approach to tied-arch bridge analysis and design (2015) Acta Technica Corviniensisbulletin of Engineering, 8 (4), p. 33; Wang, Y., Dejin, T., Seismic response analysis of tied arch bridge (2016) 2016 International Conference on Civil, Structure and Environmental Engineering, , Atlantis Press; Krishnan, A.R., Leslie, R., Unnikrishnan, S., Damage detection in bowstring girder bridge using dynamic characteristics (2015) International Journal of Engineering Research & Technology (IJERT), pp. 168-171; Qiu, W.L., Kao, C.S., Kou, C.H., Tsai, J.L., Yang, G., (2010) Stability Analysis of Special-Shape Arch Bridge, 13 (4), pp. 365-373; Belevicius, R., Juozapaitis, A., Rusakevičius, D., Parameter study on weight minimization of network arch bridges (2018) Periodica Polytechnica Civil Engineering, 62 (1), pp. 48-55; Specifications, S., (1999) Code of Practice for Road Bridges.

The stress-strain curve of PUC shows that it is equally strong in tension and compression and is an elastic material. It can be used for retrofitting purposes due to their excellent strength properties, light weight and ease of application. PUC also exhibit great ductility and durability properties due to the formation of dense microstructure. It has the combined properties of polyurethane and Portland cement. There is no need for adhesives as it excellent bonding characteristics. The only practical application was in the strengthening of T-Beam Bridge in Harbin, China (2016). The possibility of PUC as a retrofitting technique has not been explored yet. In this paper the static and dynamic response of the structure retrofitted using PUC, due to seismic loading is analyzed using finite element method.

The developed crane exhibits considerable saving in construction time besides a large saving in manpower. This machine has been awarded the best technology NRDC Award. In this paper, the kinematic model of the mini climbing crane has been developed. Crane workspace and boom tip trajectory are evaluated using MATLAB programming by varying different geometrical and motion parameters. Modal analysis of the full-scale mini climbing crane is performed for its overall stability. Further finite element model (FEM) of the crane shows the load-carrying capacity of the existing design of the mini climbing crane. The full-scale 3D CAD model of the crane is used in the finite element analysis (FEA) using ANSYS software.

Once floodwaters recede, it is expected that the structure will return to normal service providing a vital link within the rural road network. The severity of the 2011 and 2013 flood events in Queensland severely damaged floodways causing a devastating impact on rural communities during the recovery and rehabilitation efforts. From these extreme flood events it was demonstrated that the resilience of these critical road structures is of great significance for the survival, safety and recovery stages of communities. Using Lockyer Valley Regional Council area as a case study, the authors have demonstrated that the majority of structural damage was sustained due to heavy impact loadings caused from boulders and logs being conveyed by floodwaters. Another aspect reviewed was the damage sustained to the floodway apron due to the excessive debris loading, this was of particular concern as concrete aprons are of a significant expense to road authorities to repair and/or replace. As a result of floodways encountering many forces throughout their serviceable life, thorough review and investigation of current design guidelines is required to improve floodway resilience. This paper utilises finite element methods and a detailed parametric analysis to investigate structural vulnerability of a single floodway type and reports the procedure used to develop structural design charts. Finally, the contribution that resulted from the structural analysis is linked with the methodology presented in current floodway design guidelines. © 2020, Springer Nature Singapore Pte Ltd.","Bridge failure; Floods; Impact load; Infrastructure; Resilience","Floods; Rural areas; Rural roads; Structural analysis; Bridge failures; Extreme flood events; Impact loads; Infrastructure; Parametric -analysis; Recurrence intervals; Resilience; Structural vulnerability; Failure (mechanical)",,,,,,,,,,,,,,,,"Drainage-Open Channels, Culverts and Floodway, 1st edn (2013) Austroads LTD, , Sydney, New South Wales; (2015) Report No. 2: Community Resililence to Flooding and Road Network Disruption.

An investigation was conducted to assess the viability of strengthening the web-cracked girders to extend their service life for the short-to-mid-term and avoid immediate replacement. The two main girders of a bridge supporting direct-fix transom-top track arrangement and bearing onto concrete piers and abutments. At the bearing locations of the abutment, both girders have developed longitudinal cracks in the webs near the bottom flange, extending from the ends of the girders past the bearing stiffeners. The investigation including engineering inspection, initial repair, ultrasound test of the initial repair, detailed Finite Element (FE) modelling and analysis of the BFB’s behaviour, strengthening design along with construction and installation are discussed and presented in this paper. Both global and local Finite Elements Analysis (FEA) of the defective BFB girders was carried out to establish the stress distribution patterns in the web and flanges, particularly in the vicinity of the cracking defects.

To ensure the quality of the results, all investigations are verified by numerical analysis.

FRP (fibre reinforced polymers). Therefore, in the frame of UE 7FP project PANTURA, three structural solutions of sandwich FRP bridge deck have been elaborated, fabricated and tested under static load. The panels are planned to form a deck slab in a vehicular girder bridge. The span of 2.4 m in a simply supported system was adopted as a typical span length. After the panels were manufactured by the vacuum assisted resin transfer molding method (VARTM) they were tested in the laboratory under static load. At the same time, a numerical model based on the finite element method was created to analyse panels’ behaviour under the test load.

For fretting wear test, both the pin and plate are made of Al–Si–Mg alloy. In fretting fatigue test, both the specimens and contact pads (bridge type) are made of Al–Si–Mg alloy. Fretting wear tests were conducted to get basic friction properties. Fretting fatigue tests were carried out at various contact pressures (100, 150 and 200 MPa). Finite element analysis was carried out to obtain the stresses at the contact, i.e., tangential stress and compressive stress. The relation between tangential stress, compressive stress, and fretting fatigue lives has been plotted for the Al–Si–Mg alloy. Based on the plot, the fretting fatigue strength prediction of Al–Si–Mg alloy was discussed. © 2020, Springer Nature Singapore Pte Ltd.","Al alloys; Contact pressure; Fretting fatigue; Fretting wear; Tangential stress","Aluminum alloys; Fatigue testing; Magnesium alloys; Al-alloy; Al-Si-Mg; Al-si-mg alloys; Contact pads; Contact pressures; Fatigue behaviour; Fretting fatigues; Fretting wear; Fretting wear test; Tangential stress; Compressive stress",,,,,,,,,,,,,,,,"Mutoh, Y., Xu, J.Q., Fracture mechanics approach to fretting fatigue and problems to be solved (2003) Tribol.

Updating mechanics-based nonlinear FE models allows for a complete and comprehensive damage diagnosis of large and complex structures. Recursive Bayesian estimation methods, such as the Unscented Kalman filter (UKF), have been used to update nonlinear FE models of civil structures; however, their use have been limited to models with a relatively low number of degrees of freedom and with a limited number of unknown model parameters, because it is otherwise impractical for computationally demanding models with many uncertain parameters. In this paper, a FE model of the Marga-Marga bridge, an eight-span seismically-isolated bridge located in Viña del Mar-Chile, is updated based on numerically simulated response data. Initially, 95 model parameters are considered unknown, and then, based on a simplified sensitivity analysis, a total of 27 model parameters are considered in the estimation. Different measurement sets, including absolute accelerations, relative displacements, strains, and shear deformations of the isolators, are analyzed to investigate the effects of considering heterogeneous responses on the estimation results. In addition, a non-recursive estimation procedure is presented and its effectiveness in reducing the computational cost, while maintaining accuracy and robustness in the estimation, is demonstrated. © Society for Experimental Mechanics, Inc. 2020.","High-dimensional parameter space; Model updating; Nonlinear finite element model; Parameter estimation","Bayesian networks; Damage detection; Degrees of freedom (mechanics); Nonlinear analysis; Parameter estimation; Sensitivity analysis; Shear flow; Structural dynamics; Structural health monitoring; Uncertainty analysis; Finite-element model updating; High-dimensional; Large and complex structures; Model updating; Non-linear finite element model; Number of degrees of freedom; Recursive Bayesian estimation; Structural health monitoring (SHM); Finite element method",,,,,"Comisión Nacional de Investigación Científica y Tecnológica, CONICYT; Fondo Nacional de Desarrollo Científico y Tecnológico, FONDECYT: 11160009","Acknowledgements R.

Straw bales, which constitute a waste product from cereals, are a sustainable solution employed for that purpose. The temperature distribution in a wall is influenced by the heterogeneity of the partition that comprises the elements characterised by higher thermal conductivity, i.e. timber frame. Thermal bridges (i.e. thermally weaker areas) in walls are conducive to the mould growth as well as condensation; thus, it is important to take these phenomena into account at the wall designing stage. The work describes a 2D heat-transfer analysis carried out with the finite element method by means of THERM software. The analysis involved several different variants of external walls and corners. The thermal parameters of the investigated straw were derived from our former research. The obtained results were shown as the values of thermal transmittance coefficient and linear thermal transmittance equivalent to timber construction. The temperature distribution for the investigated wall was presented in a graphical form. The study also involved examining the possibility of surface condensation. © Published under licence by IOP Publishing Ltd.",,"Cereal products; Computational methods; Condensation; Heat transfer; Temperature distribution; Thermal insulation; Timber; Graphical forms; Heat transfer analysis; Linear thermal transmittance; Surface condensation; Sustainable solution; Thermal parameters; Thermal transmittance; Timber construction; Thermal conductivity",,,,,,,,,,,,,,,,"Khan, T.S., Mubeen, U., (2012) Curr.

These railings are subject to deterioration due to accidents. This parametric study quantifies the effect of railing deterioration and its impact on load-carrying capacity of bridges. A total of 112 bridge cases were analyzed using finite element analysis (FEA). The FEA results for slab moments were calculated and compared to reference cases and AASHTO procedures. FEA moments for bridge cases with one railing fully deteriorated compared well with AASHTO, with the exception of one-lane bridges where the overestimation by AASHTO reaches 20% for 1 ft deteriorated length, and decreased to 10% as the deterioration length increased to 8 ft. Railing deteriorations also changed FEA edge moments significantly by underestimating moments by 40% for two-lane bridges.

Such collisions have resulted in human casualties and partial or full collapse of bridge structures. In the U.S., 15% of bridge failures were due to a vehicle collision. Increasing traffic volume resulted in an increase of collision events, especially with over-height trucks on highways. Innovative impact protection systems have become a point of interest to protect both structures and human lives. Metamaterial systems that have the ability to exhibit unusual properties such as negative stiffness behavior can dissipate high levels of energy. Such systems became a point of interest in base isolation, impact protection, and shock absorption applications. Bi-stable elements such as pre-buckled beams can be designed to exhibit negative stiffness behavior under transverse loading. Recent studies have shown that such systems can dissipate up to 70% of the input energy by transferring from one mode of buckling to another. The snap-through behavior of such elements remains in the elastic region of the material, which allows the system to recover the initial configuration after unloading. Finite element modeling (FEM) of bi-stable elements was carried out to address the bi-stability behavior and predict the force threshold as well as the amount of energy dissipated through such elements. FEM results were validated with experimental results. Key parameters that affect the behavior of bi-stable elements were investigated to study the different force thresholds and energy dissipation levels. The developed FEM can be used to predict the behavior of bi-stable elements and hence, design them in accordance with force thresholds and energy dissipation requirements. © 2019 - IOS Press and the authors.

A large number of experimental studies has been conducted to investigate the behaviour of FRP to concrete bonded joints under quasi static monotonic loading. Meso-scale finite element modelling approaches using dynamic explicit approach have also been successfully used to study the behaviour of FRP-to-concrete bonded joints. However, only few studies have been conducted on understanding the behaviour of FRP-toconcrete bonded joints under cyclic loading. This paper presents a finite element (FE) model to simulate the behaviour of FRP to concrete bonded joints under quasi static monotonic and cyclic loading. The ability of the model to predict the behaviour of FRP-to-concrete bonded joints was validated using existing experimental results.

The current review study focuses on the progressive fibre and matrix damage of FRP composite laminates using numerical modelling methods. Two finite element (FE) approaches have been investigated, namely, the bulk and discrete lamina models, on carbon fibre reinforced polymer (CFRP) and glass fibre reinforced polymer (GFRP) laminates under flexural loading. The numerical models were used to predict the elasto-plastic behaviour of the composite laminates. Energy-based constitutive models were adopted to represent the damage evolution of the composite laminates up to complete failure. The model predictions were compared with experimental data obtained from flexural tests up to failure. The suitability of the investigated FE models to predict the pre and post damage behaviour were greatly dependent on the structure and the fabrication method of the FRP composite. These numerical models offer a powerful analysis tool to accurately predict the progressive damage behaviour of the composite laminates manufactured by various processes. © APFIS 2019.

At high frequency high power conversion, providing compact and efficient transformer design solutions need to consider the magnetic, electric as well as thermal aspect thoroughly and carefully to ensure the reliability and efficiency of the whole system. Detailed design considerations for a HF isolation transformer in a DAB conversion system are presented in this paper taking into consideration the insulation, high frequency magnetics characteristics, skin-proximity effects at high switching frequency as well as the thermal-fluid interaction analysis. Special attention is paid to the leakage inductance since improper value leads to an undesirable overshoot on the device voltage which may cause the SiC failure.

Hearing aids are used as a hearing rehabilitation method for patients with hearing loss and can be classified as air conduction and bone conduction according to the sound transmission pathway. Bone conduction is advantageous over sound transmission as it does not affect the eardrum. Bone conduction systems are divided into BAHA, Bone Bridge and B81 according to the vibration transmission method. BAHA has disadvantages as it can result in skin diseases and has inconveniences, and patients are reluctant to accept Bone Bridge because it has to be implanted into the temporal bone. Due to its location on the skin, B81 can solve these problems; however, this method may reduce transmission efficiency. In this paper, we have proposed a resonance frequency analysis model of a curved beam diaphragm to solve these problems. The proposed method involved a natural frequency equation with derived parameters. An improved efficiency (vibration transmission) was confirmed using the fabricated diaphragm. In the future, the proposed method may be used in various fields. © 2019 World Scientific Publishing Company.","Actuator; diaphragm; displacement; finite element analysis; resonance frequency","Acoustic wave transmission; Actuators; Architectural acoustics; Curved beams and girders; Diaphragms; Efficiency; Finite element method; Hearing aids; Natural frequencies; Patient rehabilitation; displacement; Elderly populations; Rehabilitation methods; Resonance frequencies; Resonance frequency analysis; Sound transmission; Transmission efficiency; Vibration transmission; Audition",,,,,"HI18C1892; Ministry of Science, ICT and Future Planning, MSIP; Korea Health Industry Development Institute, KHIDI; National Research Foundation of Korea, NRF; Ministry of Science ICT and Future Planning, MSIP: 2017M3A9E2065284, 2018R1A2B2001434","This study was supported by the National Research Foundation of Korea (NRF) grant funded by the Korean government (MSIP) (Nos. 2017M3A9E2065284 and 2018R1A2B2001434) and the Korea Health Technology R&D Project through the Korea Health Industry Development Institute (KHIDI), funded by the Ministry of Health & Welfare, Republic of Korea (HI18C1892).

When typhoons have approached, bridge foundations have been broken due to the insufficient bearing capacity of the bridge column. The bridge bottoming method involves rebuilding the lower structure while keeping the bridge surface open, and transferring the load of the bridge temporarily to the temporary support frame to remove the bridge base or damaged part with insufficient strength. This is followed by replacing the removed bridge base with a new bridge foundation that meets the requirements of flood and earthquake resistance. Meanwhile, monitoring plans should be coordinated during construction using the bottoming method to ensure the safety of the bridge. In the case of this study, the No. 3 line Wuxi Bridge had a maximum bridge age of 40 years, where the maximum exposed length of the foundation was up to 7.5 m, resulting in insufficient flood and earthquake resistance. Consequently, a reconstruction plan was carried out on this bridge. This study took the reconstruction of Wuxi Bridge as the object and established a finite element model using the SAP 2000 computer software based on the secondary reconstruction design of the Wuxi Bridge. The domestic bridge design specification was used as the basis for the static and dynamic analyses of the Wuxi Bridge model. As a result of the analysis, the management value of the monitoring instrument during construction was determined. The calculated management values were compared with the monitoring data during the construction period to determine the rationality of the management values and to explore changes in the behavior of the old bridges and temporary support bridges. © 2019 by the authors.

Free vibration analyses using different modeling parameters showed that the natural frequencies increased when an anchorage was included or when the upper flange thickness was kept constant in the modeling. The maximum dynamic responses of the girder at different speeds of two trains [a high-speed train (KTX) and a freight train] were compared using different modeling parameters. Changes in the flange thickness did not have any significant effect on the maximum vertical displacement. However, the maximum acceleration of the girder for the flange modeled with the originally designed varying thickness was higher than that for the flange modeled with the average thickness as a constant. This difference became more significant as the train speed approached the critical speed of resonance. Regardless of whether the anchorage was modeled, no significant change was found in the maximum vertical displacement for both KTX and the freight train. The vertical accelerations for both the trains were generally lower when the anchorage was modeled. Particularly, the vertical acceleration for KTX near its critical speed of resonance showed larger differences among the finite element models. © 2019, Korean Society of Steel Construction.","Dynamic analysis; Fatigue; Finite element analysis; Parametric study; Railway bridges; Vibration","Anchorages (foundations); Concrete beams and girders; Dynamic analysis; Fatigue of materials; Flanges; Freight cars; Highway bridges; Plate girder bridges; Prestressed concrete; Railroad transportation; Railroads; Speed; Vibration analysis; Dynamic characteristics; Free-vibration analysis; High speed train (HST); Parametric study; Railway bridges; Vertical accelerations; Vertical displacements; Vibration; Finite element method",,,,,"Incheon National University, INU: 2016-2196","This work was supported by Incheon National University (International Cooperative) Research Grant (2016-2196).",,,,,,,,,,"(2012) ABAQUS, , Pawtucket, RI; Cheng, Y.-S., Au, F.-T.-K., Cheung, Y.-K., Vibration of railway bridges under a moving train by using bridge-track-vehicle element (2001) Engineering Structures, 23 (12), pp. 1597-1606; Chopra, A.K., (2001) Dynamic of structures, , 2, Pearson Higher Education, Upper Saddle River: 0130869732; Chu, K., Garg, V., Wang, T., Impact in railway prestressed concrete bridges (1986) Journal of Structural Engineering, 112 (5), pp. 1036-1051; (1995) Permissible Deflection of Steel and Composite Bridges for Velocities V > 160 Km/H, ERRI D 190 RP5; (1999) Rail Bridge for Speeds V > 200 Km/H, ERRI D 214; Frýba, L., A rough assessment of railway bridges for high speed trains (2001) Engineering Structures, 23 (5), pp. 548-556; Jo, J.R., Kim, D.S., Kim, Y.J., Kwak, J.W., Jang, S.Y., Three dimensional model for dynamic moving load analysis of a PSC-I Girder Railway Bridge (2013) The Korean Society for Railway, 16 (4), pp. 286-297. , (in Korean; Kang, D.M., Ahn, H.Y., Sung, D.R., Kim, S.I., Park, Y.G., Dynamic behavior analysis of Railway Bridge considering track structure, general meeting and conference (2009) The Korean Society for Railway, pp. 55-65. , in Korean; Kang, Y.J., Kim, J.H., Shin, J.H., Lee, M.S., (2011) Dynamic analysis for two plate girder Railway Bridge considering real high speed train loads, general meeting and conference, pp. 960-964. , The Korean Society for Railway (in Korean); (2016) General Requirements for Railway Bridge Design, , Korean Design Standard, KDS 47 10 45: 2016, Korea Construction Standards Center; Kwark, J.-W., Choi, E.-S., Kim, Y.-J., Kim, B.-S., Kim, S.-I., Dynamic behavior of two-span continuous concrete bridges under moving high-speed train (2004) Computers and Structures, 82 (4-5), pp. 463-474; Mao, L., Lu, Y., Critical speed and resonance criteria of railway bridge response to moving trains (2013) Journal of Bridge Engineering, 18, pp. 131-141; Mu, D., Choi, D.H., Dynamic responses of a continuous beam railway bridge under moving high speed train with random track irregularity (2014) International Journal of Steel Structures, 14, pp. 797-810; Park, J.G., Jang, P.G., Cha, T.G., Kim, C.W., Jang, I.Y., Dynamic response of PSC I shape girder being used wide upper flange in Railway Bridge (2015) Journal of the Korea Institute for Structural Maintenance and Inspection, 19 (4), pp. 125-135. , (in Korean; Shin, S.B., Kim, Y.H., Lee, H.K., Effect of prestressing on the natural frequency of PSC bridges (2016) Computers and Concrete, 17 (2), pp. 241-253; Yang, Y.B., Yau, J.D., Hsu, L.C., Vibration of simple beams due to trains moving at high speeds (1997) Engineering Structures, 19, pp. 936-944; Yoon, J.H., Choi, G.Y., Kwon, G.S., Jung, W.S., Effect of crossbeam on dynamic characteristic and safety of PSC-I Railway Bridge (2014) Korean Society of Hazard Mitigation, 12 (4), pp. 25-30. , (in Korean","Sim, H.-B.; Department of Civil and Environmental Engineering, South Korea; email: hbsim@inu.ac.kr",,,"Korean Society of Steel Construction",,,,,15982351,,,,"English","Int.

In this study, a method of FEM simulation is presented to estimate a suitable tightening torque of prosthetic. Torsion test has been carried out to find the ultimate torque secondly. The results of experimental are compared with simulation ones and shows a good agreement. A FEM modelling of occlusal loading with considering tightening torque is performed to investigate the influence of tightening torque under external loading subsequently. And the safety factor of 107 cycles is calculated based on the present modelling to judge the reliability in long-term using. The result shows that tightening torque not only affect the stress of prosthetic screw significantly but also the stress of screw-retained abutment. According to the study, a tightening torque less than 18N⋅cm is recommended to use ensure the functionality of implant system. © Published under licence by IOP Publishing Ltd.",,"Abutments (bridge); Manufacture; Prosthetics; Safety factor; Screws; Torque; External loading; FEM modelling; FEM simulations; Occlusal loading; Tightening torque; Finite element method",,,,,"Guangzhou Science and Technology Program key projects: 201906010032","This study is supported by 1) The Science and Technology Program of Nansha District, Guangzhou (Technology Development Program, No. 2017KF007); 2) The Science and Technology Program of Guangzhou (No. 201906010032);",,,,,,,,,,"Jung, R.E., Pjetursson, B.E., Glauser, R., Zembic, A., Zwahlen, M., Lang, N.P., A systematic review of the 5-year survival and complication rates of implant-supported single crowns (2008) Clin.

The developed sensor has a simple structure and can be effectively assembled into compact devices. Design/methodology/approach: A T-shaped plate, with both ends fixed on a base, is used as the substrate of the sensor. Eight strain gauges are placed in the root of the plate or near the sensor head, which can construct two full Wheatstone bridges on the upper and lower surfaces of the plate. When the x- or z-axes forces are applied to the sensor head, different deformation can be generated to the strain gauges. Therefore, the two Wheatstone bridges can be constructed with a different configuration for measuring the forces in x- or z-axes, respectively. Findings: A prototype was designed and constructed and experiments were carried out to test the basic performance of the sensor. It has been verified that the developed sensor could measure the x- and z-axes forces independently with a high resolution of 2.5 and 5 mN, respectively. Originality/value: Only one thin plate was used in the design, the forces in x- and z-axes could be measured independently and simultaneously, which made the sensor with a simple structure and compact size. Experiments were also verified that there was no crosstalk error occurred in one axis when the force was applied to the other axis. © 2019, Emerald Publishing Limited.","FEM; Force sensor; Strain gauge; T-shaped; Two-axis","Bridge circuits; Finite element method; Strain gages; Cross-talk errors; Design/methodology/approach; Force sensor; Simple structures; T-shaped; Two-axis; Two-axis force sensors; Wheatstone bridges; Plates (structural components)",,,,,,,,,,,,,,,,"Fontana, M., Marcheschi, S., Salsedo, F., Bergamasco, M., A three-axis force sensor for dual finger haptic interfaces (2012) Sensors, 12 (10), pp. 13598-13616; Haddab, Y., Chen, Q., Lutz, P., Improvement of strain gauges micro-forces measurement using Kalman optimal filtering (2009) Mechatronics, 19 (4), pp. 457-462; Huang, H., Zhao, H., Wu, B., Wan, S., Shi, C., A novel two-axis load sensor designed for in situ scratch testing inside scanning electron microscopes (2013) Sensors, 13 (2), pp. 2552-2565; Johnson, P.B., Drake, K.R., Eames, I., Wojcik, A., Remote monitoring of bi-axial loads on a lifting surface moving unsteadily in water (2014) Measurement Science and Technology, 25 (12), p. 125902; Liu, T., Inoue, Y., Shibata, K., Wearable force sensor with parallel structure for measurement of ground-reaction force (2007) Measurement, 40 (6), pp. 644-653; Ma, J.Q., Song, A.G., Development of a novel two-axis force sensor for Chinese massage robot (2012) Applied Mechanics and Materials, 103, pp. 299-304; Peng, Y., Ito, S., Shimizu, Y., Azuma, T., Gao, W., Niwa, E., A Cr-N thin film displacement sensor for precision positioning of a micro-stage (2014) Sensors and Actuators A: Physical, 211, pp. 89-97; Wang, D.H., Yang, Q., Dong, H.M., A monolithic compliant piezoelectric-driven microgripper: design, modeling, and testing (2013) IEEE/ASME Transactions on Mechatronics, 18 (1), pp. 138-147","Peng, Y.; Department of Physical Education and Sports Science, China; email: yxpeng@zju.edu.cn",,,"Emerald Group Holdings Ltd.",,,,,02602288,,SNRVD,,"English","Sens.

Research in stretchable electronics has uncovered ways to build stretchable systems with inorganic materials. Island-bridge layout and structured substrate are two effective methods to build stretchable systems. This work proposes a zigzag structured substrate for stretchable solar arrays to provide levels of stretchability.A zigzag structure serves as the device island of the solar array to absorb and isolate large deformation of the substrate. An analytic model is established to analyze the stretchability of a planar zigzag structure. A stretchable solar array with a zigzag structured substrate is analyzed by FEM.The solar array with a zigzag structured substrate enables high area coverage and stretchability.

Many bridges with large-span and attractive appearance emerge unceasingly due to the use of steel. A new structure of steel ring-web beam (SRWB) was presented, which has the similar appearance with castellated steel beam. SRWB whose top and bottom slabs are connected to circular steel rings by welding or bolting uses circular steel rings to form the web. First, the structure stress characteristics of SRWB were studied. To derive the equivalent flexural stiffness and equivalent shear stiffness for SRWB, the unit stiffness method based on the theory of Timoshenko Beam was proposed. Furthermore, the deflection formula of SRWB was derived, which was validated by finite element analysis (FEA) method. The detailed design of SRWB was completed for studying bending behavior of the structure through two scale model tests. The failure mode of the first specimen under four-point loading, reflecting the inadequacy of the design, was the local instability on the edge of top slab. The failure mode of the second specimen under three-point loading was due to the local buckling of the top slab. The loading and deformation progress of the structure were obtained through two bending tests. The yield loads, strains and test phenomena were also captured through two bending tests. The FEA models of two specimens whose results are compared with the tests were realized. The stress distribution of FEA models were analyzed in order to provide reference for further improvement of design. It can be concluded that SRWB with the rational design has good bending performance. © 2019 Elsevier Ltd","Bending behavior; Deflection formula; Finite element analysis (FEA); Load-deflection curve; Steel ring-web beam (SRWB)","Bending (deformation); Bending tests; Bridges; Finite element method; Stiffness; Bending behavior; Bending performance; Flexural stiffness; Load-deflection curve; Local instability; Structure stress; Three-point loading; Web beams; Structural design",,,,,,,,,,,,,,,,"ABAQUS, Computer Software (2017), Dassault Systemes Paris; Boyer, J.P., Castellated beams - new developments (1964) Eng.

At present, the finite element mechanical analysis model for the cable saddle is not accurate enough to analyse the real stress situation. A stress analysis method of concrete under the cable saddle based on the accurate finite element model is presented in this paper. In order to obtain the exact stress results of the concrete under the saddle, this paper modelled the filament dividers in the saddle one by one, and established the loading surface element on the surface of each filament divider layer to apply the equivalent surface force layer by layer. In addition, this paper also studied the stress characteristics of the lower tower column in the tower bridge, and put forward structural reinforcement suggestions for the force of the lower tower column. The results of this paper can provide reference for the design and construction control of pylons in extradosed cable-stayed bridge. © Published under licence by IOP Publishing Ltd.",,"Cables; Concretes; Finite element method; Numerical models; Stress analysis; Towers; Design and construction; Extradosed cable-stayed bridges; Loading surface; Mechanical analysis; Security problems; Stress characteristics; Structural reinforcement; Surface forces; Cable stayed bridges",,,,,"Systematic Project of Guangxi Key Laboratory of Disaster Prevention and Structural Safety: 2016ZDK004","This research was supported by Key Laboratory of Disaster Prevention and Structural Safety of Ministry of China (grant no. 2016ZDK004).",,,,,,,,,,"Zhang, H.W., Li, Y.D., Local stress analysis of cable saddle concrete in low tower cable-stayed bridge (2009) Railway Standard Design, 1, pp. 42-44; Tan, C.J., Zhu, B., Ji, W.H., Model test of cable saddle segment in low tower cable-stayed bridge (2008) J.

The first six natural frequencies and modes of an airborne four-claw spherical stabilized platform with new materials are obtained by modal analysis using ANSYS software. In the process of establishing the finite element model, different mesh generation methods are compared, and the mesh distortion is reduced from 0.74 to 0.38 by changing the mesh correlation and refinement.

It is concluded that in the welding process, the maximum temperature field does not appear at the center of the heat source, but around the heat source. The farther the free end is from the weld zone after welding, the larger the deformation is. After welding, the overall stress on the upper surface of the weld is larger than that on the middle and lower surface of the weld.

The results indicate that: an approximately linear relationship exists among the gasket contact stress, bolt preload and working medium load. When the pressure is gradually increasing, the flat end-plate's outward convex deformation results in the decreasing gasket stress in the center and even leakage. After locating the above leakage reason, the flange gasket structure is improved, and the bolt distribution and bolt preload is adjusted accordingly. The problem of leakage has been solved, approves that the calculating method of gasket sealing is an effective approach. © Published under licence by IOP Publishing Ltd.","Dry Evaporator; Finite Element Analysis; Non-axisymmetric Gasket; Static Sealing","Bolts; Bridge decks; Finite element method; Glass ceramics; Heat exchangers; Manufacture; Occupational risks; Axisymmetric; Calculating methods; Deformation result; Effective approaches; FEM (finite element method); Gasket contact stress; Linear relationships; Static sealing; Gaskets",,,,,,,,,,,,,,,,"Roos, E., Kockelmann, H., Hahn, R., Gasket characteristics for the design of bolted flange connections of metal-to-metal contact type [J] (2002) International Journal of Pressure Vessels and Piping, 79 (1), pp. 45-52; Ge, Y., Li, X., Zhang, J., Ma, S., Finite element analysis of diesel engine gasket seals[J] (2011) Railway Locomotive&Car, 31, pp. 184-187; Feng, X., Gu, B., Research on leakage model of Metallic gasket seal[J] (2006) Lubrication Engineering, 8, pp. 78-80; Chen, Y., Guan, K., Ma, K., Gasket stress analysis of bolted flanged joints based on metal to metal contact[J] (2015) Pressure Vessel, 32, pp. 36-41; Liu, Y., Research on the assembly pattern and leakage of bolted flange joint with Metal-to-Metal Contact [D] (2014) Journal of East China University of Science and Technology(Natural Science Edition); Du, K., Liu, M., Gasket stress analysis based on bolt flange connection system [J] (2013) Mechinery Design & Manufacture, 5, pp. 88-90; Liu, L., Gu, B., Li, C., The effect of maximum stress located at gasket outer periphery on leakage of bolted flanged connections[J] (2012) Machinery Design & Manufacture, 5, pp. 196-198; Bo-Qin, G., Ye, Z., Zhu, D., Prediction of leakage rates through sealing connections with nonmetallic gaskets[J] (2007) Chinese Journal of Chemical Engineering, pp. 837-841; Liu, T., Chen, J., Non-axisymmetric tube and shell heat etphanger 3D FEA[J] (2009) Pressure Vessel Technology, 26, pp. 27-31; Du, K., (2013) Non-asbestos Gasket Sealing Property and Failure Analyze[D]; Pu, L., Ji, M., (2006) Journal of Machine Design[M]","Zhang, X.; Zunyi Normal College Institute of TechnologyChina; email: zhangxu_xaut@163.com",,,"Institute of Physics Publishing","2019 6th International Conference on Advanced Composite Materials and Manufacturing Engineering, ACMME 2019","22 June 2019 through 23 June 2019",,153085,17578981,,,,"English","IOP Conf.

Impact of a rigid cylindrical projectile on a square fabric clamped along its four edges were simulated using commercially available software LS-DYNA. To reveal the role of friction in ballistic impact, comparative study was conducted in which projectile velocity, boundary condition, and material property are kept the same but friction between projectile and fabric and between yarns themselves are varied systematically. Results from the study show that the friction between projectile and fabric has little effect on fabric energy absorption but the friction between yarns themselves has apparent effect. Fabric has larger impact energy absorption capacity when friction coefficient between yarns are smaller. Smaller friction between yarns delays initiation of yarn failure, increases the duration of interaction between projectile and fabric and thus increases impact energy absorption capacity of fabric structure. © 2019 Published under licence by IOP Publishing Ltd.",,"Biomaterials; Bridge decks; Energy absorption; Fatigue crack propagation; Friction; Glass ceramics; Projectiles; Yarn; Comparative studies; Fabric structures; Friction coefficients; Impact energy absorption; Plain weave fabrics; Projectile impact; Projectile velocity; Three dimensional finite element analysis; Weaving",,,,,,,,,,,,,,,,"Bazhenov, S., Dissipation of energy by bulletproof aramid fabric (1997) Journal of Materials Science, 32 (15), pp. 4167-4173; Briscoe, B.J., Motamedi, F., The ballistic impact characteristics of aramid fabrics: The influence of interface friction (1992) Wear, 158 (1-2), pp. 229-247; Cheeseman, B.A., Bogetti, T.A., Ballistic impact into fabric and compliant composite laminate (2003) Composite Structures, 61 (1-2), pp. 161-173; Das, S., Determination of inter-yarn friction and its effect on ballistic response of para-aramid woven fabric under low velocity impact (2015) Composite Structures, 120, pp. 129-140; Duan, Y., Modeling friction effects on the ballistic impact behavior of a single-ply high-strength fabric (2005) International Journal of Impact Engineering, 31 (8), pp. 996-1012; Tabiei, A., Nilakantan, G., Ballistic impact of dry woven fabric composites: A review (2008) Applied Mechanics Reviews, 61 (1)","Guo, D.; School of Taiyuan University of TechnologyChina; email: 1224016371@qq.com",,,"Institute of Physics Publishing","2019 6th International Conference on Advanced Composite Materials and Manufacturing Engineering, ACMME 2019","22 June 2019 through 23 June 2019",,153085,17578981,,,,"English","IOP Conf.

To solve the problem of bending deformation of the motorized spindle, aiming at the traditional cam grinder, the structure of grinding spindle is designed with active control of electromagnetic bearing. Due to the influence of centrifugal inertia force on deformation, the equation of deformation of the rod is deduced, and the relationship between minimum distortion of the motorized spindle and the displacement of grinding wheel end and the electromagnetic loading force is obtained. The finite element method is used to analyze the relationship between the minimum bending deformation of motor The most suitable electromagnetic force to restrain the spindle is received at different rotational speeds due to the deflection of the motorized axis. The results show that the deviation of grinder spindle is effectively suppressed by applying appropriate electromagnetic force. Reduce the vertical displacement of the spindle grinding wheel end.

Domestic and foreign scholars have done a lot of calculations and experiments on this, and believe that when the support system of the roll neck (roll neck, bearing and bearing seat) suffers the roll bending force, the four-row cylindrical roller bearing suffering the radial bending force may be eccentric due to the hyperstatic structure of the mechanism in which the bearing block cannot be synchronously bent with the roller neck, thereby causing bearing damage. In this paper, the integrated model of the roll neck support system of the roll is established by SolidWorks, which is introduced into ANSYS-Workbench for contact surface setting, loading and constraint, and finally the roll neck bending deflection and bearing roller contact stress are analyzed and verified, which confirmed the validity of integrated deformation and mechanical analysis of roll neck support system by finite element method. © Published under licence by IOP Publishing Ltd.",,"Bending (deformation); Bending (forming); Bridge decks; Glass ceramics; Rollers (machine components); Stress analysis; Adhesion failures; Ansys workbenches; Bearing rollers; Bending deflection; Hyperstatic structures; Integrated modeling; Mechanical analysis; Support systems; Bearings (machine parts)",,,,,,"This work was financially supported by Suzhou Manakin Aluminum Processing Technology Co.

In order to make the photoelectric stabilization platform smaller and lighter, a four-claw spherical photoelectric stabilization platform is proposed. The four-claw spherical photoelectric stabilization platform is driven by piezoelectric motors with parallel structure. SolidWorks software is used to build the three-dimensional model of the stabilized platform. After reasonable simplification, the finite element model is built in ANSYS software. Comparing different mesh generation methods in the process of establishing finite element model, the mesh distortion is reduced from 0.74 to 0.38 by changing the mesh correlation and refinement. Different materials are used to design the platform, and the mass of the platform under different materials is compared. The platform mass of the new material is 30.3% and 66.4% less than that of the other two materials. The static characteristics of the platform with new materials are analyzed, and the maximum deformation and stress of the platform are analyzed.

Effective mechanical joint equivalent models are established to solve the practical problem of the dynamic model engineering. Equivalent models of joint surface in this study include spring damping method, virtual material method and Bond connection method. Firstly, the model is established by CATIA. Secondly, the physical properties of the model are assigned by ANSYS or Abaqus finite element simulation software. Then the modal analysis of the model carries out. By comparing the mode shapes and natural frequencies of the three methods, it is concluded that the mode shapes of the three methods are basically the same. Therefore, all three methods are reliable joint surface equivalent models. However, the natural frequency obtained by the virtual material method is significantly lower than the natural frequencies obtained by the other two methods.

The residual stress of the V-groove Q235 butt plate was measured by borehole method. The accuracy of the numerical simulation results was verified by experimental method. The influence of groove shape on welding is deduced by simulation. Because the V-groove fills the most metal during welding, the deformation of V-groove is the largest, while the deformation of K-groove and X-groove is much smaller due to the symmetrical distribution of filling metal. Considering the actual welding process and simulation results, the X-groove should be opened as far as possible if the thick plate is welded. In order to simplify the process, a V-shaped groove should be made for 12 mm thick steel plate, and a 60 degree groove should be made as far as possible. © 2019 Published under licence by IOP Publishing Ltd.",,"Biomaterials; Bridge decks; Deformation; Elastoplasticity; Glass ceramics; Manufacture; Numerical methods; Residual stresses; Borehole method; Elastic-plastic finite element method; Experimental methods; Stress field; Thick steel plates; V-shaped grooves; Welding process; Welding stress; Welding",,,,,,,,,,,,,,,,"Zeng, H., (2004) Materials Mechanics Experiments [M]; Liu, R., (2009) Experimental Study and Finite Element Analysis of Residual Stress of Welded Box Members with Excessive Width-thickness Ratio [D]; Nawwar, A.M., McLachlan, K., Shewchuk, J., A modified hole-drilling technique for determining residual stresses in thin plates (1976) Experimental Mechanics, 16 (6), pp. 226-232; Nawwar, A.M., Shewchuk, J., On the measurement of residual stress gradients in aluminum alloy speciments (1978) Experimental Mechanics, 18 (7), pp. 269-276; Ruud, C.O., A review of selected non-destructive Method for Residual Stress Measurment (1982) NDT Int., 15 (1), pp. 15-23",,,,"Institute of Physics Publishing","2019 6th International Conference on Advanced Composite Materials and Manufacturing Engineering, ACMME 2019","22 June 2019 through 23 June 2019",,153085,17578981,,,,"English","IOP Conf.

But the need is to develop a single unit which could perform both of these operations efficiently and simultaneously. The paper discusses about the development of dozer bucket mechanism as a single unit to perform dozing and loading operation and connected to the amphibious infantry combat vehicle. To develop the dozer bucket mechanism synthesis of mechanism (Linkages and Boom) has carried out and care has taken to fulfill the above stated functional requirement and satisfy the geometrical constraints. The synthesis of mechanism is done with the help of 'CATIA' software packages. The force calculation on various joints at the different position of mechanism has evaluated with the help of 'ADAMS' software. The finite element analysis has done using software 'ANSYS'. The developed mechanism combines the dozing and loading operation and connected to the tracked vehicle. © 2019 SAE International.

In horizontally curved and skew bridges, these braces can engage adjacent girders to act as a system to resist the potentially large forces and torques caused by the curved or skewed geometry. However, because of their role in laterally transmitting live load forces, they can produce fatigue cracks at their connections to the girders. This paper investigates a method for evaluating the distribution of fatigue stress ranges using finite element analysis (FEA), through user-defined subroutines in conjunction with commercial FEA software. Data from field testing under various load passes of a weighed load vehicle of a skewed steel girders bridge are used to validate the results. A case study of an intermediate cross-frame was adapted in order to show the advantage of using this stress analysis methodology, which locates the stress concentration regions where distortion-induced fatigue cracks may originate. This knowledge can then be applied in later work to assess and optimize the fatigue performance of typical bridges and connection details. © 2019 IEEE.","Cross-frames; Fatigue; Field-testing; Finite-element-analysis; Skew-bridges; Steel-bridge","Cracks; Fatigue crack propagation; Steel beams and girders; Steel bridges; Stress analysis; Subroutines; Concentration region; Connection details; Distortion-induced fatigue; Fatigue performance; Forces and torques; Steel girder bridge; Structural elements; Structural modeling; Fatigue of materials",,,,,,,,,,,,,,,,"(2017) Load and Resistance Factor Design Specifications, , AASHTO LRFD 8th Ed., Washington, DC: American Association of State Highway and Transportation Officials; Wang, W., Battistini, A., Helwig, T., Engelhardt, M., Frank, K., Staggered bracing in skewed steel bridge (2011) Proc., Annual Stability Conf.

However, existing thermal models cannot offer a complete explanation for the complex coupling phenomenon. In this paper, an improved lateral-coupling thermal impedance model (ILTIM) of a half-bridge IGBT module is proposed. In this model, the coupling behavior between IGBT and diode chip is asymmetric, which can get the chip's temperatures more accurately. Moreover, a simple parameter-extraction method for ILTIM based on the combination of finite element method (FEM) and circuit equations is employed. Finally, the experiments show that the ILTIM can predicate junction temperatures exactly in different inverter operations. © 2019 IEEE.","Power module; thermal cross-coupling; thermal impedance matrix; thermal impedance model","Electric inverters; Insulated gate bipolar transistors (IGBT); Circuit equation; Complex-coupling; Inverter operations; Junction temperatures; Lateral coupling; Parameter-extraction method; Thermal impedance; Thermal influence; Industrial electronics",,,,,"National Natural Science Foundation of China, NSFC: 51577074","This work is supported by the National Natural Science Foundation of China (Grant No. 51577074).","ACKNOWLEDGMENT This work is supported by the National Natural Foundation of China (Grant No. 51577074).",,,,,,,,,"Alhmoud, L., Reliability improvement for a high-power IGBT in wind energy applications (2018) IEEE Trans.

Dual Active Bridges (DAB) are often proposed for such integration since they can allow multiple sources and electrical isolation via a high-frequency transformer. In defined applications, DABs rely on the magnetizing and leakage inductance of their high-frequency transformers to achieve their performance requirement. In this paper, the inductance parameters of two types of two-winding transformers are investigated using the Finite Element Analysis (FEA) software ANSYS Maxwell. The variation of the inductance values due to the windings' distribution and core geometry was studied by establishing a parametric analysis. Prototypes were built and tested to compare the inductances actual measurements versus the simulation results. Exploring the possibility of characterizing the inductances of a transformer from a simulation standpoint is of interest in order to construct customized transformers with the optimal characteristic required in a specific DAB design. © 2019 IEEE.","dual-active bridge; FEA simulation; inductance; renewable energy integration; transformers","Electric transformers; Electric windings; Energy efficiency; High frequency transformers; Winding; Battery energy storage systems; Dual active bridges; Electrical isolation; FEA simulation; Parametric -analysis; Performance requirements; Renewable energy integrations; Two winding transformer; Inductance",,,,,"National Science Foundation, NSF: 1757207","ACKNOWLEDGMENT This work was partially supported by the US Department of Energy, Energy Storage Program (managed by Dr. Imre Gyuk), and by the NSF Grant #OIA-1757207.",,,,,,,,,,"De Doncker, R.W.A.A., Divan, D.M., Kheraluwala, M.H., A three-phase soft-switched high-power-density dc/dc converter for high-power applications (1991) IEEE Transactions on Industry Applications, 27 (1), pp. 63-73. , Jan.-Feb; Zhao, B., Song, Q., Liu, W., Sun, Y., Overview of dual-Active-bridge isolated bidirectional dc-dc converter for high-frequency-link power-conversion system (2014) IEEE Transactions on Power Electronics, 29 (8), pp. 4091-4106. , Aug; Dinesh, V., Shiva Prasad, E., Simulation of dual active bridge converter for energy storage system (2015) International Journal of Engineering Trends and Technology(IJETT), 27 (2), pp. 79-83. , September; Prapallapati, N., Ranade, S.J., Moonem, M.A., Atcitty, S., Distributed power processing based cell-level battery energy storage system (2018) 9th IEEE International Symposium on Power Electronics for Distributed Generation Systems (PEDG), , Charlotte, nc; Duncan Glover, J., Sarma, M.S., Overbye, T.J., (2012) Power System Analysis and Design, , Stamford, ct: Cengage Learning; Wittenbreder, E., Leakage inductance (part 1): Friend or foe?

Its structure and excitation load are complex. The health status of the air-cooled island has an impact on the safe operation of thermal power unit. In this paper, an optimal placement of health monitoring sensor for bridge structure of air-cooled island is proposed based on effective independence method. Through the finite element analysis, the main mode shapes of the bridge structure were obtained. Based on this, a given number of sensors were optimally arranged according to the Fisher information matrix. Then the optimal placement of the health monitoring sensor for the bridge structure of air-cooled island was obtained. The modal guarantee criterion was used to evaluate the placement scheme. The result shows that the sensor placement scheme can ensure the accuracy of modal identification and effectively reflect the structural characteristics of the bridge structure of the air-cooled island. The result can provide a reference for the health monitoring of the bridge structure of air-cooled island. © 2019 IEEE.","air-cooled island bridge; effective independence method; Fisher information matrix; health monitoring; sensor placement","Cooling systems; Fisher information matrix; Fossil fuel power plants; Health; Structures (built objects); Systems engineering; Bridge structures; Effective independence methods; Health monitoring; Modal identification; Optimal placements; Sensor placement; Structural characteristics; Thermal power units; Structural health monitoring",,,,,"2017YFC0805905","ACKNOWLEDGMENT The research was supported by the China National Key Research and Development Project(2017YFC0805905).",,,,,,,,,,"Hongxing, L., ChunLian, Z., XiaoHu, S., Air cooling fan trays harmonic response calculation and analysis (2008) Journal of Wuhan University (Engineering Science ), pp. 104-107; Xue, F., Ren, Z., Analysis of harmonic response of fan bridge truss and structural desigen (2010) Journal of Wuhan University (Engineering Science), 43, pp. 77-80; Qi, Z., Vibration characteristics analysis and contrast of bridge structures between two ACC Fans (2011) Electric Power Construction, (9), pp. 6-10; Zhao, F., Qu, T., Research on vibrational characteristics of fan bridge truss under multiple air cooling fans working condition (2012) North China University of Technology, 1 (24), pp. 68-71; Dou, R., (2010) Experimental Study on Vibration Characteristics of Air Cooling Fan System under Working Conditions, , North China University of Technology; Shao, Y., Vibration analysis of the bridge structures for the direct air cooling system (2016) Applied Energy Technology, (1), pp. 4-7; Zhou, C., Ma, Z., Song, Y., Teng, W., Hu, L., Modal analysis and test study of air-cooled island bridge (2016) Equipment Management and Maintenance, pp. 22-23; Kammer, D.C., Sensor placement for on-orbit modal identification and correlation of large space structures (1991) Journal of Guidance Control & Dynamics, 14 (2), pp. 251-259; Heo, G., Wang, M.L., Satpathi, D., Optimal transducer placement for health monitoring of long span bridge (1997) Soil Dynamics & Earthquake Engineering, 16 (7-8), pp. 495-502; Fu, Y.M., Yu, L., Optimal sensor placement based on MAC and SPGA algorithms (2012) Advanced Materials Research, 594-597, pp. 1118-1122; Poston, W.L., Tolson, R.H., Maximizing the determinant of the information matrix with the effective independence method (1992) Journal of Guidance, Control, and Dynamics, 15 (6), pp. 1513-1514; Chen, Y., Zixing, L.U., An interval effective independence method for optimal sensor placement based on non-probabilistic approach (2017) Science China(Technological Sciences), (2), pp. 16-28; Kim, T., Youn, B.D., Oh, H., Development of a stochastic effective independence (SEFI) method for optimal sensor placement under uncertainty (2018) Mechanical Systems & Signal Processing, 111, pp. 615-627",,"Guo W.Li S.Miao Q.","et al.;Key Laboratory of Aviation Technology for Fault Diagnosis and Health Management Research, AVIC SAMRI;Key Laboratory of Space Utilization, CAS;Qinda Technology Co., Ltd;Qingdao West Coast New Area Association for Science and Technology;Reliability Division of Operations and Research Society of China","Institute of Electrical and Electronics Engineers Inc.","10th Prognostics and System Health Management Conference, PHM-Qingdao 2019","25 October 2019 through 27 October 2019",,156405,,9781728108612,,,"English","Progn.

Modal identification provides mode shapes for physical quantities (acceleration strain, etc.) measured in specific directions at the location of the sensors. Besides, model updating involves the use of the mode shapes related to the nodal degrees-of-freedom of the finite element analytic model. Consequently, the mode shapes obtained by modal identification and the mode shapes of the model updating process do not coincide even for the same mode. Therefore, a method for constructing transform matrices that distinguish the cases where measurement is done by acceleration, velocity, and displacement sensors and the case where measurement is done by strain sensors was proposed to remedy such disagreement among the mode shapes. The so-constructed transform matrices were then applied when the mode shape residual was used as the objective function or for mode pairing in the model updating process. The feasibility of the proposed approach was verified by means of a numerical example in which the strain or acceleration of a simple beam was measured and a numerical example in which the strain of a bridge was measured. Using the proposed approach, it was possible to model the structure regardless of the position of the sensors and to select the location of the sensors independently from the model. © 2019 by the authors.","Measured data; Measured mode shape; Modal identification; Model updating",,,,,,,"This research was funded by the Korea Institute of Civil Engineering and Building Technology, grant from a Strategic Research Project (Smart Monitoring System for Concrete Structures Using FRP Nerve Sensor).",,,,,,,,,,"Brincker, R., Zhang, L., Andersen, P., In Modal identification from ambient responses using frequency domain decomposition (2000) Proceedings of the 18th International Modal Analysis Conference (IMAC), , San Antonio, TX, USA, 7-10 February; Juang, J.-N., Pappa, R.S., An eigensystem realization algorithm for modal parameter identification and model reduction (1985) J.

This method is based on a rational phenomenological analysis of the correspondence between the necking levels and the experimental variables (force and displacement) in plastic tension. Firstly, the definitions of the global and local inhomogeneity factors based on the statistical analysis of the radial change within the gauge section were introduced to assess the inhomogeneity degrees of post-necking specimens. In the proposed method, a number of tensile deformations with different necking levels are modeled through implanting different initial defects into specimen model in finite element analysis, respectively, outputting the corresponding simulated force–displacement curves. The inhomogeneity factors are calculated based on the intersected points between the experimental and simulated force–displacement curves. Through validation of optical measurement, it is proved that the proposed method has high accuracy and good reliability for investigating the inhomogeneous deformation with significant neck rather than those without significant neck and could exactly replace optical measurement, especially when the camera needs high resolution and acquisition frequency. This indicates it is feasible to utilize the force versus stroke curve in metal plastic forming to quantitatively analyze the localization behavior under general stress states besides uniaxial tension, concerning the contribution of initial defects. © 2019, The Brazilian Society of Mechanical Sciences and Engineering.","Finite element analysis; Force–displacement curve; Necking; Optical measurement; Tension","Bridge components; Defects; Deformation; Ductile fracture; Metal analysis; Numerical methods; Optical data processing; Optical variables measurement; Displacement curve; Force and displacements; Inhomogeneous deformation; Metal plastic forming; Necking; Optical measurement; Phenomenological analysis; Tension; Finite element method",,,,,"National Natural Science Foundation of China, NSFC: 51575230, U1810208; Department of Science and Technology of Jilin Province: 20190302059GX; National Basic Research Program of China (973 Program): SQ2018YFB130444/03","The National Key Research and Development Program of China (No. SQ2018YFB130444/03) and the Natural Science Foundation of China (Nos. 51575230 and U1810208) are greatly acknowledged.

The L-shaped plate is seen as an assembly of three rectangular portions connected by undetermined displacements and moments along the common boundary. Analytical functions for warping displacements of each rectangular portion are constructed according to elastic plate theory, and closed-form solutions are derived based on boundary conditions and compatibility between portions. Verifications are conducted by employing Finite Element Method and agreeable resultants are demonstrated for warping displacements and in-plane stress components, especially for the stress concentration around the corner of the cutout. Besides, a cutout ratio ρ is introduced to testify the feasibility of plate theory in solving the warping deformation of L-shaped plate. Results show that the rational range of cutout ratio for the model of L-shaped plate is identified 0.13<ρ < 0.25, and the variation of the shape of cutout hardly makes any significant influence on the warping deformation at loading corner for L-shaped plate. © 2019 Elsevier Ltd","Compatibility; Cutout; L-shaped plate; Perforated diaphragm; Plate theory; Warping","Box girder bridges; Curved beams and girders; Deformation; Diaphragms; Compatibility; Cutout; L-shaped; Plate theories; Warping; Perforated plates",,,,,"China Postdoctoral Science Foundation: 2017M620789; Beijing University of Technology, BJUT: 004000514118567, 004000514119060; China Scholarship Council, CSC: 201906545013","This work is supported by China Scholarship Council [Grand number: 201906545013 ], China Postdoctoral Science Foundation [Grand number: 2017M620789 ] and Beijing University of Technology [Grand number: 004000514118567 , 004000514119060 ].",,,,,,,,,,"Wright, R.N., Abdel-Samad, S.R., Robinson, A.R., BEF analogy for analysis of box girders (1968) J.

The validity is verified through comparison of the proposed method and FEM. Methods/Statistical analysis: The basic model was selected for the IPMSM with an output of 15 kW. The bridge reluctance is assumed to be 2T, ignoring the leakage reluctance of the basic model and the rotor and stator reluctance.The barrier form is finally derived using a equivalent magnetic circuitfor complementing and improving the gap flux density. Findings:Equivalent magnetic circuit is applied to IPMSM. The equivalent magnetic circuit shows the average of the relative permeability verified by FEM, the relative permeability of the saturated part of the barrier and the value of the stator relative permeability, the leakage magnetic resistance, the rotor magnetic resistance and the stator The assumption is made that magnetic resistance is ignored. In addition, assuming that the flux density of the barrier is 2T, an error occurs between the FEM and the equivalent magnetic circuit. As a result of confirming the equivalent magnetic circuit, the gap flux density is increased by increasing the length of the barrier. Comparing the characteristics of the basic model with the final model complemented by the equivalent magnetic circuit, it can be seen that the torque ripple decreases and the torque increases as the air gap flux density increases. Improvements/Applications: The air gap flux density is compared with FEM through a equivalent magnetic circuit to derive an improved the air gap flux density through the equivalent magnetic circuit. © 2019 SERSC.","Equivalent magnetic circuit; FEM; IPMSM; Saturation; The air gap flux density",,,,,,"Ministry of Trade, Industry and Energy, MOTIE: 20184030201900; Korea Institute of Energy Technology Evaluation and Planning, KETEP","This work was supported by the Korea Institute of Energy Technology Evaluation and Planning(KETEP) and the Ministry of Trade, Industry & Energy(MOTIE) of the Republic of Korea (NO.20184030201900).",,,,,,,,,,"Akaki, R., Takahashi, Y., Fujiwara, K., Matsushita, M., Takahashi, N., Morita, M., (2013) Effect of Magnetic Property in Bridge Area of IPM Motors on Torque Characteristics, 49 (5), pp. 2335-2338. , May; Lee, H.W., Lee, K.D., Kim, W.H., Jang, I.S., Kim, M.J., Lee, J.J., Lee, J., (2011) Parameter Design of IPMSM with Concentrated Winding considering Partial Magnetic Saturation, 10 (10), pp. 3653-3656; Kim, S.-I., Lee, G.-H., Hong, J.-P., Jung, T.-U., (2008) Design Process of Interior PM Synchronous Motor for 42-V Electric Air-Conditioner System in Hybrid Electric Vehicle, 44 (6), pp. 1590-1593. , May; Kim, D.-J., Hong, D.-K., Choi, J.-H., Chun, Y.-D., Woo, B.-C., Koo, D.-H., (2013) An Analytical Approach for a High Speed and High Efficiency Induction Motor considering Magnetic and Mechanical Problems, 49 (5), pp. 2319-2322. , May; Chen, L., Hopkinson, D., Wang, J., Cockburn, A., Sparkes, M., O’Neill, W., (2015) Reduced Dysprosium Permanent Magnets and Their Applications in Electric Vehicle Traction Motors, 51 (11); Jae-Hak Choi, D.-K.H., Yon-Do Chun, D.-J.K., Dae-Hyun Koo, B.-C.W., (2013) Development of a High Speed Induction Motor for Spindle Systems, 49 (7), pp. 4088-4091; Nair, D.G., Arkkio, A., Inverse Thermal Modeling to Determine Power Losses in Induction Motor (2017) IEEE Transactions on Magnetics, 53 (6); Mun, J.-M., Park, G.-J., Seo, S.H., Kim, D.-W., Kim, Y.-J., Jung, S.-Y., Design Characteristics of IPMSM With Wide Constant Power Speed Range for EV Traction (2017) June, 53 (6); Iyer, K.L.V., Lai, C., Mukundan, S., Dhulipati, H., Mukherjee, K., Kar, N.C., Investigation of Interior Permanent Magnet Motor With Dampers for Electric Vehicle Propulsion and Mitigation of Saliency Effect During Integrated Charging Operation (2019) Feb, 68 (2), pp. 1254-1265; Yang, Y., Castano, S.M., Yang, R., Kasprzak, M., Bilgin, B., Sathyan, A., Dadkhah, H., Emadi, A., Design and Comparison of Interior Permanent Magnet Motor Topologies for Traction Applications (2017) Mar, 3 (1), pp. 86-97; Mallick, P.K., Satapathy, B.S., Mohanty, M.N., Kumar, S.S., Intelligent technique for CT brain image segmentation (2015) 2015 2Nd International Conference on Electronics and Communication Systems (ICECS), pp. 1269-1277","Kim, K.-C.; Dept. of Electrical Engineering, South Korea; email: kckim@hanbat.ac.kr",,,"Science and Engineering Research Support Society",,,,,20054238,,,,"English","Int.

Piezoelectric patches are usually applied with other structures to form piezoelectric actuators to expand the capability and use of piezoelectric patches. In this paper, a new piezoelectric actuator based on the ancient Chinese arch structure is proposed. The piezoelectric actuator is mainly composed of a bow device and several piezoelectric plates. Firstly, the electromechanical coupling model of the cantilever beam structure is established based on the finite element method. The action characteristics of the bow-type piezoelectric actuator are studied. Then static analysis of the cantilever beam with the bow-type piezoelectric actuator is applied. The effect of the bow-type piezoelectric actuator on the cantilever beam under different parameters is analysed and compared, including actuation voltages, locations and physical dimensions of the bow-type structure. Especially, the thickness of the device and the span of the bow device are optimized to better capability. The simulation results show that the thickness and the span of the bow-type device in the bow-type piezoelectric actuator affect the action of the piezoelectric actuator on the cantilever beam remarkably. Additionally, the bow-type piezoelectric actuator is easy to install, simple to manufacture, and can be reused. The research in this paper will provide a reference for the active control or energy harvesting of structural vibration. © Published under licence by IOP Publishing Ltd.",,"Arch bridges; Cantilever beams; Electromechanical coupling; Energy harvesting; Nanocantilevers; Piezoelectric materials; Piezoelectricity; Structural dynamics; Actuation voltages; Design and simulation; Electrical energy; Mechanical energies; Physical dimensions; Piezoelectric patch; Piezoelectric plate; Structural vibrations; Piezoelectric actuators",,,,,"National Natural Science Foundation of China, NSFC: 11702162; Natural Science Foundation of Shandong Province","This research received financial support from National Natural Science Foundation of China (Grant No. 11702162) and Natural Science Foundation of Shandong Province (Grant No. ZR2018LE014 and ZR2016EEM12).",,,,,,,,,,"Wang, Q., Wang, C.M., Optimal placement and size of piezoelectric patches on beams from the controllability perspective (2000) Smart Materials and Structures, 9 (4), p. 558; Kumar, K.R., Narayanan, S., Active vibration control of beams with optimal placement of piezoelectric sensor/actuator pairs (2008) Smart Materials and Structures, 17 (5); Zhang, Z., Xu, Feng, M.B., Zhang, X., Research for a new actuator with variable step and large displacement (2010) International Journal of Applied Electromagnetics and Mechanics, 33 (1-2), pp. 597-604; Wang, W., Yang, Z., A compact piezoelectric stack actuator and its simulation in vibration control (2009) Tsinghua Science and Technology, 14 (S2), pp. 43-48; Luo, Y., Xie, S., Zhang, X., Vibration control of honeycomb sandwich panel using multi-layer piezoelectric actuator (2008) Computers & Structures, 86 (7-8), pp. 744-757; Bruant, I., Gallimard, L., Nikoukar, S., Optimal piezoelectric actuator and sensor location for active vibration control, using genetic algorithm (2010) Journal of Sound and Vibration, 329 (10), pp. 1615-1635; Roy, T., Chakraborty, D., Optimal vibration control of smart fiber reinforced composite shell structures using improved genetic algorithm (2009) Journal of Sound and Vibration, 319 (1-2), pp. 15-40; Mehrabian, A.R., Yousefi-Koma, A., Optimal positioning of piezoelectric actuators on a smart fin using bio-inspired algorithms (2007) Aerospace Science and Technology, 11 (2-3), pp. 174-182; Foutsitzi, G., Gogos, C., Hadjigeorgiou, E., Stavroulakis, G., Actuator location and voltages optimization for shape control of smart beams using genetic algorithms (2013) In Actuators, 2 (4), pp. 111-128; Vijaya, M.S., (2016) Piezoelectric Materials and Devices: Applications in Engineering and Medical Sciences; Ikeda, T., (1996) Fundamentals of Piezoelectricity; Jaffe, B., (2012) Piezoelectric Ceramics, 3; Moheimani, S.R., Fleming, A.J., (2006) Piezoelectric Transducers for Vibration Control and Damping",,,,"Institute of Physics Publishing","2nd International Conference on Modeling in Mechanics and Materials","29 March 2019 through 31 March 2019",,152402,17578981,,,,"English","IOP Conf.

Torsion of cylindrical and prismatic rods of various cross-section is of great practical utility and technical importance in engineering, structural design and mechanical work. Machine construction, steel bridges, ship buildings and brake systems are just some of the main areas of application. Calculation of the shear stress distribution due to a torsional moment is a complicated problem. Although several solutions have been formulated over time, only a few have analytical forms. In many situations the torsion problem was solved numerically using 2-dimensional Finite Element method.

These construction loads affect the global and local stability of the girders and produce permanent girder rotation after construction. In addition to construction loads, the skew angle of the bridge also contributes to girder rotation. To prevent rotation (in both skewed and non-skewed bridges), a number of techniques have been suggested to temporarily brace the girders using transverse tie bars connecting the top flanges and embedded in the deck, temporary horizontal and diagonal steel pipes placed between the webs of the exterior and first interior girders, and permanent cross frames. This study includes a rigorous three-dimensional finite element analysis to evaluate the effectiveness of several bracing systems for non-skewed and several skewed bridges. In this paper, skew angles of 0°, 20°, 30°, and 45° were considered for single- and three-span bridges. The results showed that permanent cross frames worked well for all bridges, whereas temporary measures have limited application depending on the skew angle of the bridge. © 2019 Techno Press.

The paper demonstrates the influence of corrosion on a stringer beam and on a cross-girder beam of a particular steel truss railway bridge in Slovakia. This is an important step in the assessment of the loading capacity and the residual lifetime of this bridge. A simple beam FEM model was refined by modelling the investigated members as plate elements. In such a way the real boundary conditions of the members were modelled most realistically by keeping the model as simple as possible at the same time. The stresses in the members were first calculated with the original cross-sectional dimensions and the results were compared with the real measured corroded cross-sections. A future corrosion rate was estimated and calculation of this case was also performed. The influence of stringer to cross-beam rigidity, the size of 2D FEM elements, and the steel material model (linear, bilinear with 1% hardening) were investigated too. © Published under licence by IOP Publishing Ltd.",,"Corrosion rate; Environmental engineering; Railroad bridges; Railroads; Steel corrosion; Stringers; FEM modeling; Loading capacities; Plate elements; Railway bridges; Residual lifetime; Riveted railway bridges; Simple beams; Steel materials; Steel bridges",,,,,"Slovenská Akadémia Vied, SAV: VEGA 1/0773/18","This paper has been supported by the Scientific Grant Agency of the Ministry of Education, science, research and sport of the Slovak Republic and the Slovak Academy of Sciences – grant VEGA 1/0773/18.",,,,,,,,,,"EN 1993-1-1. 2005 Eurocode 3: Design of steel structures - Part 1-1: General rules and rules for building; EN 1993-2. 2006 Eurocode 3: Design of steel structures - Part 2: Steel Bridges, October; RFEM 5 2016 Program Description (Prague: Dlubal Software s.r.o.); Kochariacute, J.K., Imrich, V., (2007) Metoacute;da Koneccaron;nyacute;ch Prvkov v Teoacute;rii A Priacute;kladoch Department of Production Technologies Koscaron;ice","Štecák, R.; Slovak University of Technology in Bratislava, Slovakia","Katunsky D.Mesaros P.Harbulakova V.O.",,"Institute of Physics Publishing","11th International Scientific Conference of Civil and Environmental Engineering for PhD.

In this paper, the simulation software ABAQUS is used to simulate a hot roll-forming process of LTU-rib. Finite element model of hot roll-forming process was established. The influence of the pass design schemes and temperature parameters on the hot roll-forming process was analyzed and discussed. The simulation results show that first scheme is more suitable for hot roll-forming process. Although forming temperature can reduce the roll-forming force and improve the metal fluidity, excessive temperature will lead to redundant deformation.

This paper presents a follow-up parametric investigation of the influence of railing stiffness on the wheel load distribution in simply-supported, one-span, three- and four-lane reinforced concrete slab bridges using the finite-element analysis (FEA). A total of 48 bridge cases are modeled using refined 3D FEA and bridge parameters such as span lengths, slab widths, and railings that were varied within practical ranges. Various railings stiffness were considered to be built integrally with the bridge deck and placed on both edges of the concrete slabs. The FEA wheel load distribution and bending moments are compared with reference bridge slabs without railings as well as to the AASHTO design procedures. According to the FEA results, the presence of railings reduces the longitudinal bending moment in the concrete slabs by 25% to 60% depending on the stiffness of the railings in one- and two-lane reinforced concrete bridges. However, when considering three- and four-lane bridges, the presence of railings reduced the longitudinal bending moment in the concrete slab by a range of 10% to 32% depending on the stiffness of railings. The results of this investigation will assist bridge engineers in better evaluating the load carrying capacities of multi-lane concrete slab bridges using 3D FEA and account for the contribution of railings. The presence of railings can also be considered a possible alternative for strengthening existing concrete slab bridges. © Int. J. of GEOMATE.

The microgripper offers parasitic motionless linear motion of the gripper jaw. The design integrates a bridge-type mechanism and parallelogram mechanisms in such a way that a pure linear motion of the gripper jaw in the grasping direction can be achieved. The analytical modeling is developed to find the output displacement, the displacement amplification ratio, and the natural frequency of the mechanism. Finite element analysis (FEA) is conducted to verify the results obtained from analytical modeling. The FEA results show that a jaw displacement of 353 μm with a displacement amplification ratio of 17.65 can be achieved. The parasitic motion can be reduced to 0.012 % of the gripper jaw motion in the x-direction. The modal analysis shows that the first natural frequency of 207.81 Hz can be achieved.

Such plates have to be light and easy to handle, hence the use of composite materials is favourable. The investigated ‘dimpled plates’ are designed with glass fibre reinforced polymer (GFRP) and built to withstand high loads and to allow maximum deformation. Design parameters for the dimensioning of the plates are derived from standard ASTM laminate testing, and the values are used for the optimization of the plates by means of FEM (shape; composites layup). The verification of the component resistance and strength, however, requires adapted test configurations and procedures. Global loading of the structure has to replicate the situation in the field, and the resulting failure modes have to be identified for further optimization of the system. The scale of the plate bending tests had to be minimized due to large deflections. Mainly shear failure (delamination) and compressive failure (fibre buckling or crushing) were observed. Negative boundary effects had to be minimize in the tensile test, too. Fibre tensile failure followed after delaminations in the fillet of the knop base. Transverse compression: Testing against hard parallel plates provided high strength values, but the setup did not reproduce the situation of a soft bedding in the field, with mud. Different scenarios of elastic bedding over rubber plates were compared. The results provided the basis to optimize the material choice for the laminate (resin type, fibre reinforcement). The durability of the final composite laminates was verified with extensive aging tests in a later study. © 2019 Elsevier Ltd","Bending strength; Compressive testing; Dimpled composite plate; GFRP laminate plate; Glass fibre reinforced polymers","Bending (forming); Bending strength; Bending tests; Bridge decks; Columns (structural); Compressive strength; Durability; Fiber reinforced plastics; Glass fibers; Laminated composites; Plates (structural components); Polymers; Reinforced plastics; Reinforcement; Tensile testing; Composite plates; Compressive failure; Compressive testing; Fibre reinforcements; GFRP laminates; Glass fibre reinforced polymers; Hard parallel plates; Transverse compression; Failure (mechanical)",,,,,"11230.1 PFIW-IW","The study was financed by the Swiss Commission for Technology and Innovation CTI/KTI with the fund No. 11230.1 PFIW-IW .

Instrumentation of the striker extended the scope of this inexpensive dynamic test significantly. By not only recording the absorbed energy but also the force applied to the specimen as a function of time, additional information about the material's properties is obtainable. At the present day, however, no internationally accepted procedure to calibrate or verify the measured dynamic force exists. From an engineering viewpoint, an instrumented striker for which a static force calibration is sufficient to accurately measure the force applied to the specimen during a Charpy impact test would be ideal. To investigate if such an instrumented striker can be designed, the influence of the striker geometry, the location of the strain gauges, and the static force calibration procedure on the force measured by an instrumented International Organization for Standardization striker is assessed using finite element analysis. It is demonstrated that when the strain gauge bridge on the striker is sensitive to the load distribution at the striking edge, the voltage response for the Charpy impact test deviates from the static force calibration curve, and the conversion of the voltage readout to force values introduces an error in the force value and hence a discrepancy between computed and angle-based energies. A striker with a height of 12 mm and strain gauges positioned at 17 mm from the striking edge is nearly insensitive to the load distribution, and a static force calibration is sufficient to accurately measure the force during an impact test. © 2019 by ASTM International","Charpy impact testing; Design optimization; Dynamic force; Finite element analysis; Instrumented strikers; International Organization for Standardization","Calibration; Electric power plant loads; Finite element method; International cooperation; Strain gages; Charpy v notches; Design optimization; Dynamic forces; Function of time; Instrumented strikers; International organization for standardizations; Load distributions; Voltage response; Charpy impact testing",,,,,,,,,,,,,,,,"Manahan, M., Siewert, T., The history of instrumented impact testing (2006) Journal of ASTM International, 3 (2), pp. 1-9. , https://doi.org/10.1520/JAI12867, February; Kobayashi, T., Inoue, N., Morita, S., Toda, H., On the accuracy of measurement and calibration of load signal in the instrumented charpy impact test (2000) Pendulum Impact Testing: A Century of Progress, pp. 198-209. , https://doi.org/10.1520/STP14395S, T.

In particular, their basic structural response is indeed logical enough, explicit and simple although its required numerical computation procedure is, in a little bit, boring. This type of structures have gained increasing popularity and offers more advantages than more complex structures, such as cylindrical shells, arches and right folded plate frames. Similarly, the thin-walled cellular bridge decks can be treated as a multi-folded plates structure. This study produces an overall review of the historical development of the most popular methods utilized for analysis the folded plate structures which are offered with their applications and how these methods are developed gradually. Four common methods are chosen in this paper to show their highlights of references particularizing in analysis of the above mentioned types of structure; the folded plate elasticity method (FPEM), finite element method (FEM), finite strip method (FSM) and spline finite strip method (SFSM). This investigation covers the elastic behavior, and the experimental researches on the elastic reaction of folded plate structures. © Published under licence by IOP Publishing Ltd.",,"Arch bridges; Strip metal; Sustainable development; Thin walled structures; Architectural appearance; Economic advantages; Experimental research; Finite strip method; Folded plate structure; Historical development; Numerical computations; Spline finite strip method; Plates (structural components)",,,,,,,,,,,,,,,,"Wang, Y., Analysis of continuous folded plate roofs (1965) Masters Theses, p. 6694; Goldberg, J.E., Leve, H.L., Theory of prismatic folded plate structures (1957) Publs.

Signal sensing and feedback are the key links. In this paper, a reinforced flexible hybrid nanogenerator (NG) based on PVDF/ZnO is designed. In the hybrid mode, the open circuit voltage can reach 70 V, the short circuit current can reach 12 μA, and the output performance can be increased by 25%. In this experiment, the charge density of the PVDF/ZnO surface was 12.79 μC/m2, the power density was 1.22 μW/cm2, and a 500 μF supercapacitor could be filled in 100 s. Through finite element analysis and experimental tests, it is proved that it is a more sensitive self-powered flexible hybrid sensor, which can accurately record the amplitude and frequency of human motion.

The rotor poles of the novel integrated axial FSPM machine function as the radial impellers of the centrifugal compressor. The radial impellers rotate and accelerate the flow to increase velocity before entering the diffusers. The novel integrated axial FSPM machine is capable of producing torque for accelerating the flow while eliminating the requirement of a separate motor. Therefore, the total size of the centrifugal compressor system is significantly reduced, and high power density can be achieved. In this paper, the design and working principles of axial FSPM machine and centrifugal compressor are provided. The design tradeoffs of the integrated axial FSPM motor-compressor are evaluated.

Because of its structural complexity, theoretical analysis of mechanical performances of the orthotropic steel bridge deck is very difficult. Therefore, in the past 50 years, a series of experiments and finite element analysis have been used to obtain the information. A steel deck–girder–rib bridge system subjected to the transverse load is investigated in this paper. The bridge deck is laid on four simply-supported girders at the four edges and is reinforced by ribs in longitudinal direction. The longitudinally stiffened deck is idealized as an orthotropic plate. The equivalent material properties in the longitudinal and breadth directions of the orthotropic plate are evaluated using micro-mechanics of composite material by treating the ribs as reinforcing fiber-beams. Governing equations for the deck–girder–rib bridge systems are established and are solved using Ritz method. The analytical solutions are substantiated by comparing with the classic solutions of an isotropic deck with fixed ends and with the finite element predictions. The analytical approach presented in this paper eliminates the very intricate and arduous kinematics study among deck–girder–rib and allows the bridge engineer to fast and convenient estimate the deformation in an orthotropic bridge deck. © 2018, Korean Society of Steel Construction.","ABAQUS finite element analysis;

Their warpage behavior during wafer-form integration will be experimentally and numerically evaluated, and also compared with wafer warpages of 2.5D assembly which applied Si interposer with TSV (through Si via). The C4-first flow is to attaching chips on wafers where the C4 bumps have been completed between mold layer and glass carrier. This flow is similar to 2.5D manufacturing process that the Si interposer was temporarily bonded on a carrier which can suppress the interposer warpage variation during reflow process. The temporary glue is required to protect the C4 bumps during chip on wafer procedures. In regarding to the cycle time and cost, the flow to complete C4 after chips attaching will be further studied. The processed induced u-bump (micro-bump) and u-pad (micro-pad) shift post jointing are observed to be larger than that in 2.5D flow. In the manufacturing process of molded wafer, the high CTE glass carriers are used to reduce CTE mismatch between molding compound and carrier. The significant wafer warpage changing from concave to convex shape was observed after chips attaching on the wafer. And the warpage will be further increased after underfilling and molding processes. To well predict and address the warpage trend, the finite element analyses are carried out to understand the process-induced warpage behaviors, and thus to select better material and process parameter. The key parameters affecting wafer warpages like material properties of molding compound, glass carrier and top-mold thickness are determined by finite element simulation. In light of the handing procedure of wafer form assembling equipment, the preferred wafer warpage shape is determined by experimental results. Finally, the test vehicle have been assembled with substrate as well. The chip module warpage in 2.5D structure is about double than that with molding interposer at 230°C and reversed direction in a convex shape, which is different from molding chip module. © 2019 IEEE.","C4 first; C4 last; Chip module; Interposer","Box girder bridges; Finite element method; Glass; Microprocessor chips; Molding; Molds; Network components; Sheet molding compounds; Silicon wafers; Wafer bonding; C4 first; C4 last; Chip module; Finite element simulations; Interposer; Manufacturing process; Molding process; Process parameters; Three dimensional integrated circuits",,,,,,,,,,,,,,,,"Suk, K.L., Lee, S.H., Kim, J.Y., Lee, S.W., Lee, K.S.C., Kim, P.W., Kim, D.W., Oh, D.K.S., Low cost si-less rdl interposer package for high performance computing applications (2018) Proc.

Piotrowo 5, Poznań, 61-138, Poland","Traffic flow capacity of some old road bridges is insufficient due to limited deck width. In such cases bridge deck widening is a common solution. For multi-girder reinforced concrete (RC) bridges it is possible to add steel-concrete composite girders as the new outermost girders. The deck widening may be combined with bridge strengthening thanks to thickening of the existing deck slab. Joint action of the existing and the added parts of such bridge span must be ensured. It refers especially to the horizontal plane at the interface of the existing slab and the added concrete layer as well as to the vertical planes at the external surfaces of the initially outermost girders where the added girders are connected to the existing bridge span. Since the distribution of the added concrete is non-uniform in the span cross-section the structure is particularly sensitive to the added concrete shrinkage. The shrinkage induces shear forces in the aforementioned planes. Widening of a 12 m long RC multi-girder bridge span is numerically analysed to assess the influence of the added concrete shrinkage. The analysis results show that: a) in the vertical plane of the connection of the added and the existing deck slab the longitudinal shear due to the shrinkage of the added concrete is comparable with the effect of live load, b) it is necessary to provide appropriate longitudinal reinforcement in the deck slab over the added girders due to tension induced by the shrinkage of the added concrete.

The approach is based on three-dimensional finite element analyses and is in line with the methodology adopted in the Eurocode 8—Part 5 (2004) lumped spring approach. The method of extraction of various stiffness values from the finite element model is described, followed by obtainment of the closed-form solutions. Parametric study revealed the nominal effect of the embedment length of Double-D caissons, and hence only the width and diameter effects are included in the suggested formulations. The obtained results are presented in terms of multiplication factors for Double-D caissons. Final impedance functions for a given width and diameter of a Double-D caisson can be conveniently estimated by multiplying the proposed functions to the circular shaft solutions available in literature. The applicability of the proposed formulations is demonstrated by considering a typical bridge pier supported by Double-D caissons. The proposed formulations require a minimum amount of input parameters and can be used during the tender design to arrive at the required geometry of such foundations.

Thus an inspectionmethod instead of weight hoisting power was proposed. Based on the finite element method, an analysis model of the bridge crane structure under the stress state is established, and the simulation result is obtained. According to the theoretical analysis, the proposed experiment is carried out in realistic bridge cranes, applying the hanger in crane to stress the wire rope fasten in the bottom of the main beam, stress strain test is also applied to the typical region. The final result indicates that the numerical analysis model is with high reliability, and the experimental method is practical in the bridge crane research. © Published under licence by IOP Publishing Ltd.",,"Numerical methods; Reliability analysis; Analysis models; Crane structures; Experimental methods; High reliability; Numerical analysis models; Static loading test; Stress state; Stress-strain tests; Bridge cranes",,,,,,,,,,,,,,,,"Design Rules for Crane: GB/T 3811-2008 S; Shi, L., Wu, X., Huang, H., The simulation of stress intensity factor of 3D crack of girder of existing crane with FEM (2013) J.

Design of connections is one of the most critical issues in truss structures; and it becomes even more complicated when corrosion causes loss of outer steel tube section. However, behavior of composite joints is among the least understood topics in structural engineering today. Previous attempts (numerical and experimental) to study the behavior of composite joints have focused mainly on the effect of sustained loading. But the widespread use of CFST structures in harsh, marine environment necessitates observing the performance of composite joints under corrosion alongside long-term loading. The aim of this paper therefore is to study the combined effect of chloride corrosion and sustained loading on circular composite K-joints through finite element analysis (FEA). The results thus obtained have been presented and verified against experimental observations of previous researchers. For a side by side comparison with composite K-joints, FEA has also been established for circular hollow section (CHS) K-joints. In addition to these, failure modes and load-deformation characteristics of both the composite and hollow K-joints have been thoroughly investigated under various practical loading cases and different corrosion scenario. From numerical analyses, it has been observed that corrosion in infilled chord leads to only 4% loss of joint strength whereas, corrosion of equal intensity in hollow braces decreases the joint capacity by 35%. Finally, joint strength and ductility have been predicted based on the full-range numerical analyses. Concrete infills have been found to enhance the joint strength by 2.5-3.0 times. © Published under licence by IOP Publishing Ltd.",,"Beams and girders; Chlorine compounds; Concretes; Joints (structural components); Numerical analysis; Seawater corrosion; Steel corrosion; Structural design; Trusses; Tubular steel structures; Chloride corrosion; Circular hollow section; Concrete-filled steel tubular; Load deformation; Long-term loadings; Marine environment; Sustained loading; Transmission tower; Loading",,,,,,,,,,,,,,,,"Han, L.H., Li, W., Bjorhovde, R., Developments and advanced applications of concrete-filled steel tubular (CFST) structures: Members (2014) Journal of Constructional Steel Research, 100, pp. 211-228; Han, L.H., Hou, C., Wang, Q.L., Square concrete filled steel tubular (CFST) members under loading and chloride corrosion: Experiments (2012) Journal of Constructional Steel Research, 71, pp. 11-25; Hou, C., Han, L.H., Zhao, X.L., Full-range analysis on square CFST stub columns and beams under loading and chloride corrosion (2013) Thin-Walled Structures, 68, pp. 50-64; Han, L.H., Hua, Y.X., Hou, C., Wang, Q.L., Circular concrete-filled steel tubes subjected to coupled tension and chloride corrosion (2017) Journal of Structural Engineering, 143 (10), pp. 04017131-04017134; Wardenier, J., Packer, J.A., Zhao, X.L., Vegte, G.J., (2010) Hollow Sections in Structural Applications, , (Delft: Bouwen met Staal); Huang, W., Fenu, L., Chen, B., Briseghella, B., Experimental study on K-joints of concrete-filled steel tubular truss structures (2015) Journal of Constructional Steel Research, 107, pp. 182-193; Saleh, S., Hou, C., Han, L.H., Hua, Y.X., Numerical behavior of composite K-joints subjected to combined loading and corrosive environment (2018) 12th International Conference on Advances in Steel-Concrete Composite Structures ASCCS 2018, , (Valencia-Spain,); Han, L.H., Tao, Z., Liu, W., Effects of sustained load on concrete-filled hollow structural steel columns (2004) Journal of Structural Engineering, ASCE, 130 (9), pp. 1392-1404; Song, Q.Y., Han, L.H., (2010) Tubular Structures XIII - Young (Ed), , (Hong Kong: The University of Hong Kong) FE analysis of composite tubular K-joints subjected to static loading; Hou, C., Han, L.H., Mu, T.M., Behaviour of CFDST chord to CHS brace composite K joints: Experiments (2017) Journal of Constructional Steel Research, 135, pp. 97-109","Saleh, S.; Department of Civil Engineering, Bangladesh; email: shameer.saleh@uap-bd.edu",,,"Institute of Physics Publishing","10th Asia Pacific Structural Engineering and Construction Conference 2018","13 November 2018 through 15 November 2018",,147607,17578981,,,,"English","IOP Conf.

This paper presents characteristics of a novel totally decoupled two degree-of-freedom (2-DOF)nano-positioning stage driven by piezoelectric (PZT)actuators. In order to achieve large stroke positioning, a symmetrical structure with new bridge type amplifiers based on single notch flexure hinges is utilized in this nano-positioning stage. By connecting the PZT actuators and bridge type amplifiers, the stage can realize decoupled motion in X and Y directions. The static characteristics of bridge type amplifier is investigated to explore the input stiffness, output stiffness and amplification ratio.

One intact specimen and one damage specimen with fracture at mid-span section were tested under static load test. By comparing the pre- and post-fracture behavior, significant reduction of system stiffness and load carrying capacity are observed. Nevertheless, composite twin I-girder bridge system will not collapse under dead load and be able to carry sufficient live load which qualifies the bridge as a redundant system in fracture condition. Meanwhile, by using finite element method with nonlinear analyses, fracture at different sections are analyzed. Results proved that the fracture of whole web and bottom flange at mid-span section is the most fracture critical location comparing to fracture at other locations. In addition, by comparing the performance of one girder and twin-girder models, the adjacent girder can be concluded as an essential component that ensures the safety of the composite twin I-girder bridge system in fracture condition. © 2019, © 2019 International Association for Bridge and Structural Engineering (IABSE).","composite twin I-girder bridges; fracture critical location; nonlinear analyses; Post-fracture; safety level","Fracture mechanics; Location; Nonlinear analysis; Critical location; Experimental and numerical studies; I-girders; Post-fracture; Redundant system; Safety level; Static load tests; System stiffness; Fracture",,,,,"Waseda University: 2015A-503, 2018K-231","This research is sponsored by Waseda University Grant for Special Research Project-A (The key funding, Project number: 2015A-503) and Waseda University Grant for Special Research Project-K (The key funding, Project number: 2018K-231).

The bridge, built in 1985, has three spans with simply supported stiffening trusses and earth-anchorage system. Over time, the suspension bridge suffered from a considerable variation of configurations and serious degradation of structural components, which directly affected the load-resistance mechanism and endangered the safety of the bridge. A comprehensive scheme was proposed to adjust structural configurations including the reduction of dead load, the tension of the main cables and the length adjustment of hangers. As for the degraded components, maintenance and replacing works were carried out. On-site measurement and detailed finite element model (FEM) analysis were used to evaluate rehabilitation performance. Through applying the proposed scheme, the Dalian North Suspension Bridge was successfully transferred to a structure that met the demand for safety, serviceability and durability. © 2019, © 2019 International Association for Bridge and Structural Engineering (IABSE).","Case study; configurations adjustment; dead load reduction; hanger replacement; main cable tension; rehabilitation; suspension bridge","Cables; Patient rehabilitation; configurations adjustment; Dead loads; hanger replacement; Main cable; On-site measurement; Rehabilitation works; Structural component; Structural configurations; Suspension bridges",,,,,"National Natural Science Foundation of China: 51778108","The authors acknowledge the support pro vided by National Natural Science Foun dation of China.

Operators establishing ice crossings over rivers and lakes have been facing increased pressure to deliver higher volumes of goods, larger loads, in challenging climatic conditions. A question arose from industry: “is there a way to safely provide additional bearing capacity in ice covers and assist with extending operating seasons, possibly through reinforcing the ice?” This study investigated this operational challenge by developing a model to simulate ice reinforcement theories using ANSYS computer modeling techniques. ANSYS 18.0 was utilized to successfully model reinforced ice covers and estimate the ice deflection under a centrally concentrated load. ANSYS computer models allow us to learn complex behaviours of materials and provide a more accurate estimation of deflection compared to the analytical method, which provides a closed-form solution to a given problem. The results show that the reinforcing material is able to stiffen the ice cover which enables a larger surface area to carry the load; a higher percentage of the reinforcement by volume further reduces ice deflection. The test results also indicate that the reinforcing material must be considerably stiffer than the ice so that the load can be more efficiently transferred from the ice to the reinforcing material. The results highlight a successful modelling of reinforced ice covers and discuss the feasibility of installing the reinforcing material, through an example using wood as a possible reinforcing material because it is readily available on site and meets a number of pre-determined criteria. While the creation of an ice reinforcement modeling tool was a success, further research is needed to verify the feasibility of using a variety of materials as reinforcement to increase the safe bearing capacity of ice covers as well as evaluate different applications and orientations of the reinforcement to achieve the best outcome. All of this bearing in mind that the reinforcement must be able to be safely installed in situ within the ice cover. Moreover, a collection of actual ice deflections in the field is recommended to further assist in calibrating the ANSYS model. The simulations serve as an initial step in evaluating different reinforcement materials and methodologies. Subsequent research will need to evaluate the modelling in controlled, full-scale field applications prior to providing a tested solution for commercial use. © 2019, Springer Nature Switzerland AG.","ANSYS model; Elasticity; Finite element analysis; Ice cover; Reinforcing material","Bearing capacity; Bridges; Deflection (structures); Reinforcement; Climatic conditions; Closed form solutions; Computer modeling techniques; Operational challenges; Reinforcement materials; Reinforcement theory; Reinforcing materials; Transportation links; Ice",,,,,"Natural Sciences and Engineering Research Council of Canada, NSERC","We are genuinely thankful for the sponsorship and industry support for this study.

The effect of the compression of arch bridges creates a large horizontal load. Therefore, it is one of the most important factors in the dimensioning of piles. The study aims to make a comparative study between the results obtained in the field, and those obtained by a 3D model defined as a Finite Element (FE) of a drilled pile, subjected to different lateral loads applied at exact time intervals. Moreover, the study was intended to determine the influence of the lateral load applied to a different pile diameter using the FE model. Thus, the unified FEA software Abaqus. by Dassault systèmes®carried out various processing procedures, namely soil FE modeling, pile FE modeling, soil-pile interface, Mesh, and boundary conditions, to carry out an effective and predictive piles behavior analysis. Based on the Mohr-Coulomb criterion, the soil is considered to be stratified with elastoplastic behavior, whereas the Reinforcement Concrete Pile (RCP) was assumed to be linear isotropic elastic, integrating the concrete damage plasticity. Since the bridge is an arched bridge, the lateral load induced was applied to the head of the piles through a concentrated force to check the pile strength, for which the displacement, stress and strain were taken into account throughout, along the pile depth. The lateral displacement of the pile shows a deformation of the soil as a function of its depth, with different layers crossed with different lateral loads applied. Thus, from the study comparing the results of the FE measurements with the data measured in the field, added to the statistical analyses are as follows: Decrease of the displacement and stress according to the diameter, taking into account the different diameter. The foundations receive loads of the superstructure to be transmitted to the ground. Thus, the piles are generally used as a carrier transmitting loads on the ground. One of the important factors in the durability of the bridge depends more on the strength of these piles. This makes it necessary to study the reinforced concrete foundations because of their ability to resist loads of the structure, and the vertical and lateral loads applied to the structure. This implies an evaluation of the responses of the RCP according to the different lateral loads. © 2019 by the authors.","3d finite analysis; Lateral load; Reinforced concrete pile; Stress-strain behavior",,,,,,"2014013","Funding: This work is supported by Heilongjiang Transport Technology Project Grant no. 2014013.",,,,,,,,,,"Kourkoulis, R., Gelagoti, F., Anastasopoulos, I., Gazetas, G., Slope stabilizing piles and pile-groups: Parametric study and design insights (2011) J.

However, the reliability of the switches still remains a matter of concern. During design phase of the RF MEMS switches, the surfaces of switch are considered to be smooth at micro scale and the effect of surface roughness is neglected. The theme of the present paper is to quantify surface roughness effect on the static pull in voltage and gap of an electrostatically actuated RF MEMS switches by providing a simple analytical model along with the FEM (Finite Element Modeling) simulations. The surface roughness effect on the static pull in voltage of RF-MEMS capacitive switches becomes severe in case of small distance between the suspended top bridge and bottom dielectric. The results in the paper shows that the value of pull in voltage and gap decreases whereas value of capacitance increases as radius of spherical surface roughness increased. The pull in voltage value of the capacitive switch for an air gap thickness of 0.5 μm and 2.5 μm decreases by approximately 27% and 23% from its smooth surfaced value for a roughness scale of 0.1 μm respectively. The results are important for the search of an ideal switch and are in good agreement with the mathematical model. © 2019 IEEE.","FEM simulations; Pull in gap; Pull in voltage; Reliability; RF MEMS switches; Surface roughness","Capacitance; Electric switches; Electrostatic actuators; Finite element method; MEMS; Microelectromechanical devices; Military applications; Reliability; Air gap thickness; FEM simulations; Pull-in; Pull-in voltage; Radio frequency microelectromechanical systems; RF MEMS capacitive switches; RF-MEMS switches; Surface roughness effects; Surface roughness",,,,,,,,,,,,,,,,"Rebeiz, G.M., RF MEMS switches: Status of the technology (2003) Ann Arbor, 1001, pp. 48109-52122; Rebeiz, G.M., (2004) RF MEMS: Theory, Design, and Technology, , John Wiley & Sons; Girbau, D., Electrothermally actuated RF MEMS switches suspended on a low-resistivity substrate (2007) Journal of Microelectromechanical Systems, 16 (5), pp. 1061-1070; Lin, T.-H., A study on the performance and reliability of magnetostatic actuated RF MEMS switches (2009) Microelectronics Reliability, 49 (1), pp. 59-65; Pamidighantam, S., Pull-in voltage analysis of electrostatically actuated beam structures with fixed-fixed and fixed-free end conditions (2002) Journal of Micromechanics and Microengineering, 12 (4), p. 458; Lee, H.-C., Park, J.-Y., Bu, J.-U., Piezoelectrically actuated RF MEMS DC contact switches with low voltage operation (2005) IEEE Microwave and Wireless Components Letters, 15 (4), pp. 202-204; Yao, J.J., RF MEMS from a device perspective (2000) Journal of Micromechanics and Microengineering, 10 (4), p.

Thus, it is also essential to simulate the fracture of the packages. In this paper, three different test samples were prepared to predict the warpages from the assembly process and material properties by finite element method. From the comparison between experimental study and numerical calculation, it seemed that the initial warpage of the samples was close to zero during the molding process of epoxy-mold-compound (EMC) due to the pressing of a metal mold onto the warping samples. Thus, the warpage of the samples after the molding process could be roughly predicted by using the stress free temperature of EMC defined as the molding temperature in this paper. Furthermore, we found that the calculation including the contribution of the chemical shrinkage of EMC was more effective to simulate the warpages. © 2019 IEEE.",,"Box girder bridges; Metal pressing; Microelectronics; Microsystems; Molds; Behavior analysis; Chemical shrinkage; Epoxy mold compounds; Molding temperature; Numerical calculation; Reliability design; Semiconductor packages; Stress-free temperature; Metal molding",,,,,,,,,,,,,,,,"Miyaki, K., Thermo-viscoelastic analysis for warpage of ball grid array packages taking into consideration of chemical shrinkage of molding compound (2004) Journal of Japanese Electronics Society, 7 (1), pp. 54-61; Nakamura, S., Tanaka, T., Shinohara, T., Theoretical and experimental study of warp deformation behavior with chemical reaction and thermal load for viscoelastic laminated body (2008) Journal of the Society of Materials Science, 57 (11), pp. 1153-1159. , Japan; Gale, W.F., Totemeier, T.C., (2004) Smithells Metals Reference Book, p. 14. , (8th edition.), Elsevier, Burlington 1-pp. 15-3; Wortman, J.J., Evans, R.A., Young's modulus, shear modulus, and poisson's ratio in silicon and germanium (1965) Journal of Applied Physics, 36 (153), pp. 153-156; Gupta, S.A., (2003) TEMPERATURE and RATE DEPENDENT PARTITIONED CONSTITUTIVE RELATIONSHIPS for 95. 5PB2SN2. 5AG SOLDER ALLOY, , University of Maryland, College Park, MD M.

Recently, existed bridges and vehicles loading mechanism have influenced many studies to predicate the dynamic bridge response and monitor damage occurrence. The objective of present study is set to monitor the Penang (I) Bridge using finite element model to verify the positioning of sensors. 3D model was developed to evaluate the modal parameter’s momentous attitude alteration of the bridge selected grid points and elements. Discussion is focused upon the output parameters such as displacements and stresses generated by vehicles weights. Three types of vehicles were chosen for the purpose of crossing the bridge. In conclusion, from the six lanes of the bridge, high displacements were obtained at the lane 6 (the most left or right side lane) due to vehicles loads at the grid points while maximal stresses were enhanced at lane 6 and 4 (either of the two middle lanes) of the chosen girder beam at bridge spans and cable elements of the infrastructure. Subsequently, sensors were positioned at the grid points in lane 6 and elements located at both lanes due to the mixed loading events. © BEIESP.","Cable stayed bridge; Dynamic traffic load; Finite element method; Structural health monitoring; Weight in motion",,,,,,"International Islamic University Malaysia, IIUM: RIGS17-033-0608","The support of International Islamic University Malaysia under the research grant RIGS17-033-0608 is gratefully acknowledged.",,,,,,,,,,"Roy, K., Ogai, H., Bhattacharya, B., Ray-Chaudhuri, S., Qin, J., Damage Detection of Bridge using Wireless Sensors (2012) In IFAC Workshop on Automation in the Mineral and Metal Industries, 45 (23), pp. 107-111; Shigeishi, M., Colombo, S., Broughton, K.J., Rutledge, H., Batchelor, A.J., Forde, M.C., Acoustic emission to assess and monitor the integrity of bridges (2001) Journal Construction and Building Materials, 15 (1), pp. 35-49; Estes, A.C., Dan, M., Frangopol, and Stuart D.

This moment at onset of yielding is the strength limit state for flexural design of steel highway bridge girders, according to the AASHTO standard. Finite element analysis is used to obtain values of flexural strength reduction for girders with various magnitudes of out-of-flatness, covering a range of continuous I-shaped and tub (box) cross sections and spans. Straight girders were used since the evaluated behavior is local buckling. Models are built with co-existing out-of-flatness imperfections in both webs and flanges. The imperfection pattern is set to be compatible with the first buckling mode of the built-up cross section to match the case having the theoretical maximum effect on local buckling. ANSYS heat analysis was used to create appropriate residual stress pattern in the models. Models are laterally supported to ensure the local buckling limit state is the governing failure mode. Both Grade 50 steel and Grade 100 steel plate are considered with elastic-perfectly plastic material behavior. Large deflection theory is used to iteratively capture the secondary moments due to out-of-flatness. Maximum strength reduction implicitly allowed in accordance with the most restrictive value of out-of-flatness for continuous two-span unstiffened I-shaped plate girders by the American Welding Society D1.5 Bridge Welding Code is obtained. Strength-based out-of-flatness criteria for the bottom flange of steel tub girders are proposed as functions of bottom flange slenderness. © National Academy of Sciences: Transportation Research Board 2019.",,"Bending strength; Flanges; Highway planning; Plate girder bridges; Welding; American Welding Society; Elastic-perfectly plastic material; Imperfection patterns; Maximum strength; Secondary moments; Steel bridge girders; Strength limit state; Strength reduction; Highway bridges",,,,,,,,,,,,,,,,"Herman, R.S., (2001) Behavior of Stiffened Compression Flanges of Trapezoidal Box Girder Bridges, , Department of Civil, Architectural, and Environmental Engineering, University of Texas, Austin, TX, PhD dissertation; (2015) Bridge Welding Code – Steel, , American Welding Society, 2015, ANSI/AASHTO/AWS D1.5M/D1.5; Bathe, K.J., Wilson, E.L., Solution Methods for Eigenvalue Problems in Structural Mechanics (1973) International Journal for Numerical Methods in Engineering, 6, pp. 213-226; Bjorhovde, J., Brozzetti, J., Alpsten, G.A., Tall, L., Residual Stresses in Thick Welded Plates (1972) Welding Journal, pp. 392s-405s. , August, Welding Research Sulement; Kishima, Y., Alpsten, G., Tall, L., (1969) Welded Columns and Flame-Cut Plates: Residual Stresses in Welded Shapes of Flame-Cut Plates in ASTM A572(50) Steel, , Fritz Engineering Laboratory, Department of Civil Engineering, Lehigh University, Bethlehem, PA, Fritz Engineering Laboratory Report No. 321.2; McFall, R.K., Tall, L., A Study of Welded Columns Manufactured from Flame-Cut Plates (1969) Welding Journal, pp. 141s-153s. , April, Welding Research Sulement; Zhang, Y., (2007) Strength-based Plate Tolerances for Steel Bridge Girders, , Department of Civil, Architectural, and Environmental Engineering, University of Houston, Houston, TX, PhD dissertation; Alpsten, G.A., Tall, L., Residual Stresses in Heavy Welded Shapes (1970) Welding Journal, pp. 93s-105s. , March, Welding Research Sulement; (2013) Finite Element Program User’s Manual, , Canonsburg, PA, Version 15.0, ANSYS, Inc; Korol, R.M., Thimmhardy, E.G., Cheung, M.S., Field Investigation of Out-of-plane Deviations for Steel Tub Girder Bridges (1984) Canadian Journal of Chemical Engineering, 11, pp. 377-386; Sadovsky, Z., A Theoretical Approach to the Problem of the Most Dangerous Initial Deflection Shape in Stability Type Structural Problems (1978) Aplikace Matematiky, 23, pp. 248-266; Salmon, C.G., Johnson, J.E., Malhas, F.A., (2008) Steel Structures: Design and Behavior, , 5th ed., Pearson Prentice Hall, Uer Saddle River, NJ; (2017) Bridge Design Specifications, , 8th ed., American Association of State Highway and Transportation Officials, Washington, D.C; Asadnia, M., (2018) Out-of-Flatness Plate Tolerance for Steel I-Shaped and Tub Highway Bridge Plate Girders, , Department of Civil and Environmental Engineering, The George Washington University, Washington, D.C., PhD dissertation; Asadnia, M., Roddis, W.M.K., Modeling Out-of-Flatness and Residual Stresses in Steel Plate Girders, , Proc., Annual Stability Conference Structural Stability Research Council, Baltimore, Maryland, 10–13 April 2018","Asadnia, M.; Civil & Environmental Engineering Department, United States; email: masadnia@gwmail.gwu.edu",,,"SAGE Publications Ltd",,,,,03611981,,TRRED,,"English","Transp Res Rec",Article,"Final","",Scopus,2-s2.0-85063090500

The negative moment can be resisted by increasing the cross sections of the beams at the supports. An earlier study on the elastic lateral torsional buckling of stepped beam with continuous lateral bracing was conducted to propose new design equations. The main focus of this study is to continue the previous research considering the inelastic buckling of stepped beams. ABAQUS, a finite element method program was used to conduct the buckling analysis of the beams. A total of five different load cases were used in the analysis. The effects of the residual stress and geometric imperfection were also considered for the inelastic buckling strength. Results showed that the inelastic buckling strength exceeds the plastic moment of the section and it is not needed to focus on the inelastic range when computing the lateral torsional buckling strength. © 2019, Korean Society of Civil Engineers.","beam design; compact sections; finite element analysis; inelastic buckling; lateral bracing; stepped beam","ABAQUS; Beams and girders; Concrete slabs; Beam design; compact sections; Inelastic buckling; Lateral bracing; Stepped beams; Finite element method",,,,,"National Research Foundation of Korea, NRF: 2015-059692; Ministry of Education, Science and Technology, MEST; Ministry of Land, Transport and Maritime Affairs, MLTM: 17CTAPC132629-01","This research is supported by the Ministry of Education, Science and Technology (NRF 2015-059692) and by Ministry of Land, Transportation and Maritime Affairs (17CTAPC132629-01) of the Korean Government.

The research was based on the database regarding the resistance of 3,000 structures with different geometric and material properties. The database compared the results of multiple numerical FEM simulations using the response spectrum method and a set of criteria for assessing dynamic resistance. The requirements set forth in Eurocode 8 and its adaptations to the seismic conditions prevailing in Legnica-Głogów Copper District (Poland) were applied. Reasons were given for the selection of 1,499 structures with properties which were characteristic for the existing bridges located within the range of mining impacts which took the form of continuous surface deformations. Then, the selected group of structures was subjected to a detailed analysis of dynamic resistance based on the criterion condition regarding the strength of the spans. The influence of geometric and material properties of a selected group of bridge structures on shaping the permissible values of vertical accelerations of ground vibrations (av,dop ) was analyzed. The results of preliminary analyzes made it possible to build a statistical predictive model. It was demonstrated that this model, using only basic geometric and material properties, allowed to replace the complex dynamic analysis of the discussed criterion.

Piles are commonly used to support bridge structures, tall buildings, transmission line towers etc. where poor subsoil conditions are encountered. To suit the various types of structures and their loading conditions, piles of different types, shapes and sizes are being used in practice, the safety of these structures mainly depends on the ability of supporting piles to resist large amount of lateral forces. These lateral forces may be due to the action of wind in case of onshore structures and due to combination of wind and wave action in case of offshore structures.

For example, in mechanotransduction, mechanical stimuli can be introduced through macroscopic-scale contacts, which are transduced to mesoscopic-scale (micron) distances and can eventually lead to microscopicscale (nanometer) conformational changes in membrane-bound protein or protein complexes. This is a fascinating process that spans a large range of length scales and time scales. The involvement of membrane environment and critical issues such as cooperativity calls for the need for an efficient multi-scale computational approach. The goal of the present research is to develop a hierarchical approach to study the mechanical behaviors of membrane proteins with a special emphasis on the gating mechanisms of mechanosensitive (MS) channels. This requires the formulation of modeling and numerical methods that can effectively bridge the disparate length and time scales. A top-down approach is proposed to achieve this by effectively treating biomolecules and their assemblies as integrated structures, in which the most important components of the biomolecule (e.g., MS channel) are modeled as continuum objects, yet their mechanical/physical properties, as well as their interactions, are derived from atomistic simulations. Molecular dynamics (MD) simulations at the nanoscale are used to obtain information on the physical properties and interactions among protein, lipid membrane, and solvent molecules, as well as relevant energetic and temporal characteristics. Effective continuum models are developed to incorporate these atomistic features, and the conformational response of macromolecule(s) to external mechanical perturbations is simulated using finite element (FEM) analyses with in situ mechanochemical coupling. Results from the continuum mechanics analysis provide further insights into the gating transition of MS channels at structural and physical levels, and specific predictions are proposed for further experimental investigations. It is anticipated that the hierarchical framework is uniquely suited for the analysis of many biomolecules and their assemblies under external mechanical stimuli. © Springer Nature Switzerland AG 2019.

As the causes of bridge failures, climatic impacts described in many works are given. An analysis of the standard recommendations and design guidelines indicates that more precise elaboration of the recommendations for dimensioning concrete reinforcement is needed due to thermal effects. The research results presented in the article are illustrations of a selected part of the PhD Thesis analyses. The work focuses on the assessment of the impact of hot asphalt surface on the state of stress in a concrete bridge structure of a box section. From the results of numerical FEM analyses, significant internal forces are visible at this stage of construction.

Concrete structures designed for a certain load and a certain reference period, following a certain code have to be re-examined because of changes in and around the structures. The vehicle movements are changing in maximum (axle) load and/or frequency. The reference period has passed and daily use and environmental loading (corrosion, cracks) has had its impact. The loading is changed and the code is more restricted on its design formulae. For the Dutch Ministry of Infrastructure, DIANA FEA BV has made an application to assess a large amount of concrete bridge structures in an automatic way and with limited man-hour impact. The application reads data imported directly from a database file of the owner. In this file, the full geometry is defined as is the reinforcement and the supports. In addition, loads and driving lanes are defined in the database according to the codes or the actual lanes present. The application is reading the data and setting up the finite element model. Although DIANA can be used for nonlinear analysis, first a linear design calculation is performed. Based on the input of static and movable loads along the lanes, a loading generator makes all the load (combinations). The linear analyses are run, envelopes are made and consistent spreading and shifting of moments and shear forces are taken into account. The main development that has been made is an engineering flowchart for adding the correct loads on the model and governing output items for the several envelope checks. For each (integration) point in the model, a spread in the correct direction and with the correct width is constructed. This is different for the bending moments and for the shear forces. Finally, all the moments and shear forces are checked against the cross section capacities. The paper describes the flowchart, process and generation of the model.

Current procedures used for classifying structural cracking of reinforced and prestressed concrete structures generally consist of various rating criteria comprised of preestablished concrete crack width and/or length limits. While concrete cracking data obtained from routine inspections of this type can aid in identifying elements that are degrading or are exhibiting signs of distress, these inspections typically provide very limited insight into the implications of the damage. Furthermore, inspection evaluation criteria are almost always independent of member-specific details; for example, properties such as reinforcement layout and volumes, material strengths, and member geometry are usually not considered when assessing the severity of measured concrete cracking. This paper presents an overview of a smeared fixed-crack reinforced concrete membrane element analysis procedure that employs visually-measured diagonal concrete cracking data (e.g., concrete crack widths, inclinations, etc.) as input to provide estimates of concrete member material stresses, in-service load levels, and residual shear strengths. Furthermore, transverse normal stresses that arise in disturbed regions of beams are investigated in a finite element analysis parametric study. Refinements to existing models for transverse stress proportions are proposed and implemented within the crack-based assessment procedure. The procedure is shown to provide meaningful estimates pertaining to the residual capacities of full-scale reinforced concrete bent cap test specimens and in forecasting “critical” diagonal crack widths for bridge monitoring purposes. It is envisioned that idealized cracked-continuum modelling approaches, such as the type presented in this paper, can supplement traditional inspection procedures and can be used to better assess structure safety and prioritize maintenance efforts associated with growing inventories of aging and degrading reinforced concrete infrastructure. © fédération internationale du béton (fib).

This paper envisions a scenario in which accelerometers are mounted onto UAVs, which then are able to gather acceleration signals by self-attaching to the bridge. However, battery life is an issue in UAVs with the subsequent limitation in the duration of the measurements. Therefore, this paper carries out a simulation on mode shape extraction from a short data burst by utilising an output only technique, the so-called frequency domain decomposition (FDD). Modal assurance criterion (MAC) is used as a statistical indicator to check differences between the estimated mode shapes and the eigenvectors from finite element analysis. The short acceleration response is generated using a planar vehicle-bridge interaction system where the moving load is modelled as two quarter-cars and the bridge is modelled as a simply supported beam. The impact of signal noise, vehicle speed and signal duration on the accuracy of the estimated mode shapes is investigated. FDD is shown to achieve high values of MAC even for short data bursts. Damping ratio is identified as a significant source of MAC discrepancy in the extraction of mode shapes. The stiffness loss due to a crack is introduced in the beam to evaluate how damage affects the mode shape compared to operational effects. How the MAC values vary with crack location and damage severity is discussed for the first three mode shapes. © 13th International Conference on Applications of Statistics and Probability in Civil Engineering, ICASP 2019.

One of the main goals of this paper is the identification of the foremost causes of failure due to human errors in design and construction procedures. Therefore, a bridge failure database that includes several failure cases and a human errors survey will be used to support this line of work. After the identification of some explicit human errors that is believed to be the source of several reinforced concrete bridges failures, a selective analysis using risk indicators, namely, the probability of occurrence and consequence, is performed to choose those that might represent a higher risk for the structural safety. The outcome of five chosen human errors in a specific case study is quantified using a robustness index that will be computed according to the reliability index reduction of the structure due to the damages caused by the human errors, allowing to demonstrate how these errors can have a huge influence in the structural safety. The modelling and the finite element analysis of the structure will be performed using TNO DIANA software, allowing the calculation of the reliability index of the structure damaged by different human errors.

One of these attempts is to use tapered (i.e. non-prismatic with varying depth) steel plate girders with corrugated webs (TPGCWS). The corrugated steel plates are widely used as structural elements in many structural applications because of their numerous favourable properties compared with traditional flat plates. Moreover, they have been used due to their aesthetical appearance, especially in the case of TPGCWs. So many researches have been made to investigate the shear behaviour of TPGCWS for the case of simple girder, to the author's knowledge, no one has investigated the shear behaviour of TPGCWS for the case of continuous girder. So, the aim of this paper is to investigate the shear behaviour of TPGCWS for the case of continuous girder. Two experimental models have been tested to verify the finite element (FE) analysis and compare the experimental results with FE results and the existing design equations. © 2019.

The applications of this method are straightening the bridge parts, turbo-machinery shafts, and so forth. The movement of the heat source on a given path (line heating) leads to an increase in the deformation and the possibility of creating complex bends. However, it is complicated to predict and control the path and velocity of the heat source as well as determining the heat intensity. In the pipes, this method requires simultaneous control over the two torches on both sides of the pipe. The present study aims at investigating the mechanism of deformation and increasing the bending angle in thick pipes by means of a simple heating method. At first, the maximum bending in heating a large circular zone (entitled ""wide heating"") is obtained by simulating the process using finite element method and optimizing it applying the genetic aggregation algorithm. Then, a new method for simultaneous heating within two zones is introduced. The interaction between two zones leads to the development of the shortening mechanism in the pipe wall and a significant increase in the bending angle. In this method, there is no need to move the torch where the temperature is controlled more accurately. To evaluate the finite element model, several pipe heating tests are performed with their results being agreed well with the simulation results. © AFM, EDP Sciences 2019.","Finite element method; Forming; Pipe heating bending; Spot heating","Finite element method; Genetic algorithms; Heating; Machinery; Aggregation algorithms; Heat intensity; Heating method; Increasing bending; Shortening mechanisms; Simultaneous control; Small deformations; Thick-walled pipes; Bending (deformation)",,,,,,,,,,,,,,,,"Chavoshi, S.E., Moussavi Torshizi, S.E., Bending improvement in Spot Heating of pipes in comparison with Line Heating method (2019) Mech.

Much has been done so far with respect to FEM simulations of thermal bridges, but such methodology is not yet widespread in the field of acoustics. Research is needed to provide simplified formulas to be included in the new releases of the EN ISO 12354-1 standard, to overcome discrepancies between calculated and measured values. This should be done particularly for heavy junctions and combinations of heavy and lightweight junctions. In this study a validation of the simulation method has been shown, after its application to simple T-joints typical of traditional building constructions.

This trend is likely to accelerate in the coming decade according to climate change scenarios prediction. Even if, in most cases, little could be done to minimize the effect of such disasters, the design of new protecting structures should be performed so as to minimize the damage induced by fluid forces during natural hazards. A first step towards this goal is the possibility to assess, in a fast and accurate way, the interaction between the fluid, incorporating a heterogeneous mixture of water and particles of different sizes, and the surrounding terrain and infrastructures. This work will give an overview of the computational methods for the study of natural hazards involving flows with particles (or particulate flows) and their interaction and damaging effects on critical structures, such as dams, bridges, dykes. These computational methods will allow solving Particle-Fluid-Structure-Interaction (PFSI) problems to obtain an accurate and reliable prediction of the behavior of the constructions under extreme water events. This is done combining and coupling different numerical techniques ranging from Eulerian fixed grid finite elements methods, to Lagrangian particle methods such as the Particle Finite Element Method and the Material Point Method. Both Newtonian and non-Newtonian free surface flows are considered and coupled with large deformation structural mechanics models. The computational developments are implemented in the open-source software platform KRATOS (www.cimne.com/kratos). KRATOS has been developed with the goal of serving as a repository of open-source software for analysis of multidisciplinary problems in engineering. © 2019, National Technical University of Athens.

An experimental campaign was carried out to characterize the dynamic properties of the remaining spans in terms of vibration frequencies and modal shapes. For this purpose, ambient vibration tests were performed, complementing the information already available from material characterization tests. In the first part of the paper, a finite element model of the remaining bridge portion is developed and calibrated using measured dynamic test data. Subsequently, an advanced nonlinear model of the full bridge is built to simulate the scour progression and assess the modal response variation for different levels of scour. Results show a non-negligible variability of the transverse modal shape even at the early stages of the scour phenomenon, therefore calling for a deeper investigation in order to evaluate the suitability of the OMA (Operational Modal Analysis) based identification technique for scour monitoring purposes. © 2019, National Technical University of Athens.

Several studies performed by others have so far confirmed the necessity of considering correct thermal storage behavior of building envelope assemblies in dynamic hourly building energy simulations. Two and three-dimensional building envelope thermal bridges have significant impact on effective heat performance, and once coupled with the effect of heat storage, the dynamic heat transfer through the assembly can be significantly different from the one obtained from steady-state calculation methods. In this study, a simplified transient heat transfer model based on frequency response of RC-Network (FR-RCN) is presented that could generate the equivalent model for the same assembly with different continuous insulation thickness simply by systematically modifying the original RC-Network coefficients. In this study, two mass type structures are considered and their dynamic responses in a climate that is characterized with cold winter and hot summer (Toronto climate - climate zone 6) are analyzed using the proposed simplified method. As a validation exercise, the results calculated using equivalent FR-RCN are compared with solutions obtained from finite element analysis using COMSOL, and found to be in good agreement. In addition, the heat flux of the assemblies was calculated based on liner transmittance method and compared with the proposed method, and showed significant difference. In general, the FR-RCN variable insulation thickness method is found to be efficient, fast and flexible calculation method with good accuracy. © 2019 U.S. Government.",,"Frequency response; Heat flux; Heat storage; Solar buildings; Thermal insulation; Building energy simulations; Building envelopes; Dynamic heat transfers; In-depth understanding; Insulation thickness; Steady state calculations; Thermal performance of buildings; Transient heat transfer; Heat transfer performance",,,,,"Natural Sciences and Engineering Research Council of Canada, NSERC; Canada Research Chairs; British Columbia Institute of Technology, BCIT","The authors are grateful for the financial support provided by the Natural Sciences and Engineering Research Council of Canada (NSERC), Canada Research Chair (CRC) and the School of Construction and the Environment at the British Columbia Institute of Technology (BCIT).",,,,,,,,,,"Aguilar, F., Solano, J., Vicente, P., Transient modeling of high-inertial thermal bridges in buildings using the equivalent thermal wall method (2014) Applied thermal engineering, 67 (1), pp. 370-377; Carpenter, S., Advances in modeling thermal bridges in building envelopes (2001), Enermodal Engineering Limited.

A series of experimental tests were undertaken to obtain several mechanical parameters of stone columns, and mechanical characteristics of bamboo grid. The soft soil is silty clay in deep layer in which its index and engineering properties derived from oedometer tests. FEM model of a causeway embankment over bamboo grid mattress overlying deep soft soil reinforced by a group of granular columns encased with geotextile, was developed. To validate the FEM model, full scale experimental of similar model was conducted. It was found that FEM model is well agreement with the experimental model. The result explains the stress-strain behavior in bamboo grid mattress and stone columns, interacted with the soft soil as response to increasing embankment height. Bamboo grid mattress enhances the bearing capacity of the soft soil in supporting embankment leading to the decrease of settlements, while stone columns affect the acceleration of consolidation of the soft soil. The results would be beneficial for application of local natural materials such as bamboo for soft soil reinforcement as bamboo is widely available in developing Asian countries. © 2019, Springer International Publishing AG, part of Springer Nature.","Drain; Reinforcement; Settlement; Soft soil bed; Stone columns and bamboo mattress","Bamboo; Bridges; Causeways; Climate change; Embankments; Numerical models; Soil mechanics; Soil testing; Soils; Sustainable development; Embankment height; Engineering properties; Experimental modeling; Experimental test; Mechanical characteristics; Mechanical parameters; Natural materials; Stress-strain behaviors; Reinforcement",,,,,,,,,,,,,,,,"Abusharar, S.W., Zheng, J.J., Chen, B.B., Yin, J.H., A simplified method for analysis of a piled embankment reinforced with geosynthetics (2009) Geotext.

An optimised and safe design of foundation systems for high-rise structures in difficult soil and groundwater conditions is based on a reduction of construction material used, construction time spent, energy consumed and the adequate consideration of the soil-structure interaction. This is also important for the high-rise structures like skyscrapers and bridge piers in weak rock like in Dubai, UAE. Due to the large loads most of these structures are founded in the Dubai Sandstone and Dubai Siltstone. Up to now the rock mechanical parameters for these rock layers have been defined on the very conservative side which led to over-dimensioned foundations in many cases. In a large research program the bearing behaviour of Dubai Sandstone and Dubai Siltstone has been investigated by field and laboratory tests, by in-situ pile load tests and the numerical back-analysis using the Finite-Element-Method (FEM). The comprehensive research investigations show, that the stiffness of Dubai Sandstone and Dubai Siltstone is more than 20 times higher as it is assumed up to now. The paper presents the scope of research, the epoch-making results and the significance for the engineering practice. © 2019, Springer Nature Switzerland AG.","Combined Pile-raft Foundations (CPRF); High-rise Structures; Pile Head; Pile Tests; Static Pile Load Test","Bridge piers; Groundwater; Load testing; Numerical methods; Office buildings; Piles; Sandstone; Software testing; Soils; Stiffness; Structural design; Tall buildings; Comprehensive research; Engineering practices; Field and laboratory test; Foundation systems; Groundwater conditions; High rise structures; Numerical back analysis; Rock mechanical parameters; Soil structure interactions",,,,,,,,,,,,,,,,"ISSMGE International Society of Soil Mechanics and Geotechnical Engineering: Combined Pile-Raft Foundation Guideline (2013); Katzenbach, R., Bachmann, G., Leppla, S., Ramm, H.: Chances and limitations of the observational method in geotechnical monitoring.

Among these countermeasures, noise and vibration and so on complaints are identified and countermeasures are further examined and constructed, but on the other hand, in the case of low frequency noise caused by bridges, many examinations on the occurrence mechanism are required. Therefore, in this study, unsteady analysis was proposed by three-dimensional finite element method on responses of a bridge due to vehicle load running on a bridge. The numerical simulation of the low frequency noise field was carried out by calculating the three dimensional wave equations with this unsteady analysis result as an unsteady boundary condition. By this method, it became possible to quantitatively investigate to which part of the bridge the cause of the low frequency noise originates. In this paper, identification of the cause of occurrence and simulation accuracy of the propagation path were verified by using the measured results of low frequency noise and vibration acceleration. © 2019 Proceedings of the International Congress on Acoustics.

Despite the potential of these materials, joining remains an issue limiting their penetration into new markets. Research has suggested an array of interference fit micropins as a potential joining solution for composite to lightweight metal joints. We present a new approach to micropinned joints which involves interference fitting, and its effect is characterised for a composite-to-metal joint under lap shear loading. The tested joints comprised of aluminium alloys and carbon fibre reinforced polymer laminates bridged by steel pins. Micropinned joints bridged by a single pin were manufactured to attain an understanding of the response to lap shear loading. These joints showed an elastic-plastic response with ultimate load occurring when the pin was partially pulled-out. The ultimate load occurring after pull-out has begun suggests that snubbing and strain hardening of the pin have some effect on the response of the joint. Finite element analysis was able to model this response, supporting the theory of snubbing and strain hardening, adding plasticity to the joint. A square array of nine micropins was then used to manufacture micropin joints. These joints also showed an elastic-plastic response to lap shear loading with the ultimate load occurring once the pins were partially pulled-out. The total load carried by the nine pins in the square array was more than nine times the load held by one pin. The ultimate bearing stress and yield stress also increased. These results show that interference fit micropins present a potential solution for metal-to-composite joining due to the elastic-plastic response to loading. © 2019 International Committee on Composite Materials.

However, this equation may not determine the bursting force exactly because it was designed on the basis of two-dimensional numerical analyses without considering various design parameters such as the duct hole and shape of the bearing plate. To improve the design equation modification of the AASHTO LRFD design equation was considered. The behavior of the anchorage zone was investigated using three-dimensional linear elastic finite element analysis with design parameters such as bearing plate size and diameter of sheath hole. Upon the suggestion of a modified design equation for evaluating the bursting force in an anchorage block with a rectangular anchorage plate (Kim and Kwak 2018). additional influences of design parameters that could affect the evaluation of bursting force were investigated. An improved equation was introduced for determining the bursting force in an anchorage block with a circular anchorage plate, using the same procedure introduced in the design equation for an anchorage block with a rectangular anchorage plate. Hie validity of the introduced design equation was confirmed by comparison with AASHTO LRFD. © 2019 Techno Press.

Simulation of the coupled vehicle-bridge-wind-wave (VBWW) system could be very complicated. Different loading scenarios especially associated with stochastic environmental loadings from wind and waves with potential correlations have even larger computational demands. Therefore, there is a significant need in modeling the coupled VBWW more effectively. High computational efforts are also needed to establish multi-scale coupled dynamics with sub-modeling techniques to capture the stress variations in the local details that might have short cracks initiated or propagated. To account for the uncertainties resulting from stochastic loads, machine learning (ML) algorithms have been applied in the probabilistic assessment of fatigue damage accumulation for bridges. Since the performance of different ML algorithms, such as the support vector machines (SVM) and Gaussian process (GP), strongly depends on the size and structure of the data, it is necessary to check their applications on the probabilistic fatigue damage assessment. In the present study, SVM and GP are implemented to quantify the fatigue damage of bridge details based on the established probabilistic fatigue damage assessment framework for coastal slender bridges. Firstly, the long-term field measurements are employed to build parametric probabilistic models of truck loads as well as correlated wind and wave loads. In addition to these input parameters, the multi-scale finite-element analysis (FEA) were carried out based on VBWW system to obtain the dynamic stress ranges and fatigue damage accumulation. With different training strategies, the fatigue life for critical local details can be obtained considering the life-cycle changes of coastal environmental conditions. The training and testing results show that GP algorithm outperforms SVM algorithm even though SVM exhibits reasonable capability of predicting the fatigue damage accumulation. Case studies for a coastal slender coastal bridge are provided. © 2019 American Society of Civil Engineers.","coupled dynamics; fatigue damage assessment; Gaussian Process algorithm; machine learning; Slender coastal bridges; support vector machines","Damage detection; Learning systems; Stochastic systems; Support vector machines; Computational demands; Environmental conditions; Environmental loadings; Fatigue damage accumulation; Parametric probabilistic model; Probabilistic assessments; Probabilistic fatigue; Sub-modeling technique; Fatigue damage",,,,,"National Science Foundation, NSF: CMMI-1537121","This material is based upon work supported by the National Science Foundation under Grant Number (NSF Grant Number CMMI-1537121).

Under high traffic volume, these expansion devices have experienced some premature deterioration affecting the structural integrity and causing safety concerns for vehicles passing over the joint. Therefore, a group of experimental tests, in addition to 3-D elastic-plastic finite element models (FEMs), were conducted to study the structural behavior and modes of failure of finger plate expansion devices. The finite element model results have a good agreement with experimental measurements. In general, welding zones represented the sites of crack initiation in most cases of finger plate expansion devices. The present numerical results showed also that the site of the highest stress concentration was in the weld between the finger plate and the supporting beam top flange. Furthermore, other sites of stress concentrations were located at the vertical stiffener weld and the finger base curve. © 2019 American Society of Civil Engineers.",,"Deterioration; Elastoplasticity; Expansion; Finite element method; Stress concentration; Welds; Bridge deck slabs; Elastic-plastic finite element model; Expansion devices; Experimental test; Numerical results; Premature deterioration; Structural behaviors; Vertical stiffeners; Plates (structural components)",,,,,,,,,,,,,,,,"(1948) Aashto Lrfd Bridge Design Specifications, 7th Edition., , AASHTO.

Indeed, many bridge structures in the mountains collapsed due to the impact of rockfall. However, few studies have placed emphasis on clarifying the impact load of rockfall on bridge columns and how to design a rock-proof bridge, in comparison with seismic designs and others. Hence, this paper aims to clarify the dynamic behaviors of reinforced concrete bridge columns impacted by rockfall and develop a reliability-based design method for bridge columns against rockfall. Nonlinear contact-impact high-resolution finite element models (see Figure 1) were developed to investigate the performance of a bridge subjected to rockfall impact. In the high-resolution finite element model, a five-span continuous girder bridge (including girder, pier column, bearing, etc.) was adopted and modelled. The material model regarding normal concrete was carefully calibrated by drop-hammer impact test data. The influence of initial gravity loads on impact responses was found to be pronounced, and a damping-based method was proposed to efficiently exert permanent loads on pier columns before rockfall impact. Firstly, the influences of parameters regarding impact loads such as impact velocity, impact mass and impact location, were explored and discussed in detail. The most adverse impact position was identified for the impact-resistant design of a mountain bridge. Subsequently, extensive parametric studies were performed by using response surface methodology to explore the influences of structural design parameters such as reinforcement ratios and structural geometry. The developed response surface model (see Eq. (1)) was demonstrated to be capable of predicting the impact responses of bridge columns under rockfall impact well. Finally, using the developed response surface functions as the surrogate model combined with the Monte-Carlo Simulation, the reliability of the bridge columns under rockfall impact was evaluated for various impact conditions (see Figure 4 and Figure 5). The developed reliability-based analysis procedure in this paper will facilitate the development of the reliability-based design methodology for a bridge against rockfall. © 13th International Conference on Shock and Impact Loads on Structures, SILOS 2019.

The proposed method is an expanded version of the finite element method (FE) by the assistance of the Ritz method which is called RDDM (Ritz Damage Detection Method). The innovation of the proposed method in this paper is the omission of some limitations of the RDDM method, including unique support conditions, and applying the effects of ""beam and column"". In this paper, by using the shape function, the definition of support conditions as a spring, and entering the interaction effect of ""beam and column"", the equations of RDDM method are developed to provide possible damage detection of the bridges with all support conditions. Also, SVD (singular value decomposition) method is used to determine the quantity and the severity of the damage, which is sensitive to dynamic characteristics changes, originated from the damage. The efficiency and capability of the proposed method for damage detection are evaluated by a numerical sample of ""a multi-span beam"" and ""beam to column connections.

However, flight duration and battery life are substantial technical limitations. Is a short data burst sufficient for damage detection? This paper intends to answer this question by developing a novel approach based on frequency domain decomposition to obtain the mode shapes from a short data burst. Then, the modal assurance criterion is used as an indicator of the differences between the estimated mode shapes from the short data burst and the exact eigenvectors from finite element analysis. Here, the short data burst is obtained from the simulated acceleration response of a bridge beam model due to the crossing of two quarter-cars. A new damage indicator based on the modal assurance criterion profile along the beam is proposed to locate and quantify damage. © 2019 9th International Conference on Structural Health Monitoring of Intelligent Infrastructure: Transferring Research into Practice, SHMII 2019 - Conference Proceedings.

Several physics-based equations have been suggested in various standards. However, the predictions based on these equations can be different from actual measurements owing to various uncertainty sources including material properties, traffic loads, and temperature. In this study, a probabilistic method is proposed to provide a reliable probabilistic prediction on the long-term vertical deflection of bridges. The proposed method adopts Finite Element (FE) analysis model based on a conventional physics-based equation as a basis function and introduces a Gaussian process to construct a probabilistic prediction model. Based on the actual measurements of bridge vertical deflection, the parameters of the Gaussian process model are determined through optimization to maximize the probability of observing the given measurement data. The constructed Gaussian process model can provide 95% and 99% prediction intervals as well as the predictive mean on bridge vertical deflection. The proposed method is applied to an actual bridge in the Republic of Korea, and the prediction results show good agreement with the actual measurements. © 2019 9th International Conference on Structural Health Monitoring of Intelligent Infrastructure: Transferring Research into Practice, SHMII 2019 - Conference Proceedings.

Such calibrated finite element models are able to better capture and represent the actual, in-situ behavior characteristics of the structure than do the highly idealized conceptualizations and analytical models typically employed for their design. Field-measurement calibrated finite element models are generally updated by the structural identification framework using static measurements such as strains and displacements from controlled truck load tests or using dynamic characteristics such as natural frequencies and mode shapes identified from a number of possible variations of vibration testing of the structure. The selection of data types employed for the model updating will impact the required computations to minimize error functions between the experiment and finite element analysis. This study presents a comparison of the properties from a calibrated finite-element model by using different sets of static and dynamic measurements. A multi-beam highway bridge instrumented with strain transducers and accelerometers was subjected to a controlled truck load test and ambient vibration testing. The static and dynamic bridge characteristics extracted from these field tests were used to calibrate the same a-priori finite-element of the bridge. Different sets of model parameters were selected to be updated, including material properties and boundary condition. The updated model characteristics and prediction results using static and dynamic measurements are compared and evaluated. Recommendations are provided relative to the differences in the calibrated finite element models observed from each calibration approaches. © 2019 9th International Conference on Structural Health Monitoring of Intelligent Infrastructure: Transferring Research into Practice, SHMII 2019 - Conference Proceedings.

In one of the finite element models, ""solid"" elements were used; while in the other used frame elements. The models were calibrated with the results of ambient vibration. The multi-springs had the ability to represent the inelastic behavior of the structural components. Likewise, each model was analyzed for five case studies emulating scenarios the foundation pile with doubtful integrity. To determine the support's behavior, the numerical models were studied applying dynamic response analysis using a series of grond motions (i.e. synthetic earthquakes obtained from the project design spectrum). For the multi-springs model, additional non-linear static analysis (pushover) was performed to obtain the yielding displacement. According to the obtained results, it was seen that, from a structural point of view, the improved support has adequate load capacity to resist the expected acting loads. © 2019 9th International Conference on Structural Health Monitoring of Intelligent Infrastructure: Transferring Research into Practice, SHMII 2019 - Conference Proceedings.

However, local buckling, global buckling, or interaction between both is usually the main reason of significant strength and ductility loss in these columns, which eventually leads to their collapse. This paper investigates the behavior of uniform circular (C) and graded-thickness circular (GC) thin-walled steel tubular columns under constant axial and cyclic lateral loading. The GC column with size and volume of material equivalent to the C column is introduced and analyzed under constant axial and cyclic lateral loading. The analysis carried out using a finite-element model (FEM), which considers both material and geometric nonlinearities. The accuracy of the employed FEM is validated based on the experimental results available in the literature. The results revealed that, significant improvements in strength, ductility, and post-buckling behavior of thin-walled steel columns obtained using the GC column.

The dam is located in Derbendikhan city of Northern Iraq and damaged during a 7.3 magnitude earthquake which was happened 30 kilometers south of Halabja city. Derbendikhan dam which was built between the years 1956-1961 is a clay-core rock fill dam. The damage of the dam was investigated at the site right after the earthquake and some cracks were observed in the main body of the dam. The main goal of this work is to present the results of the survey which was conducted at the site and investigating the damage development mechanism through a realistic three-dimensional finite element model of the dam. As complying with the observations at the site, the finite element analysis has shown that the primary failure mechanism is due to the separation of the core and rock fill sections at the downstream side of the dam.

This paper presents analysis on sound insulation properties of carriage wallboard of high-speed trains. Finite element method (FEM) combined with acoustic-solid interaction (ASI) is applied to investigate the sound transmission loss (STL) performance. The predicted STLs are checked against experimental results, achieving good agreement in the trend. Then, the effects of several key parameters on sound insulation capability of the double-wall panel with different configurations of truss-core are systematically studied, including the inclination angle, the thickness, the configurations and its equivalent stiffness of the truss-core. To give intensive understanding of the STL behaviour, the equivalent stiffness of sound bridge is studied, which could provide some guidance for engineers from the perspective of sound insulation performance.

Thus, simplified hand calculation and line girder methods, might not be enough when bridges are to be analyzed. Refined methods, termed by AASHTO, have to be adopted. This paper has investigated the closeness and difference between curved bridge finite element models using 2-D gird and 3-D shell elements of I-girders, both are part of AASHTO refined method. Moreover, the results are calibrated by comparing analysis result with various two-dimensional and three-dimensional computations with varied curvature effects. It is concluded that when introducing torsional effects to finite element models, the modified torsional constant J with consideration of warping effect should be taken into the 2-D grid model as a refined model. When using 3-D shell elements as the refined model, stiffeners and connection plates play an important role of global model stiffness and should not be ignored, especially for sharp curved steel I-girder bridges.

According to the 2017 American Society of Civil Engineers’ infrastructure report card, more than 9% of the bridges in the United States were labeled structurally deficient. For steel bridges, the most dominant deterioration form is corrosion, which is characterized by the metal area loss resulting in structural capacity reduction. Corrosion is very common in steel multi-girder bridges because of moisture exposure, leakage through bridge joints as well as the frequent use of deicing detergents during the winter season in cold regions. Over the years, the rust can be serious enough to disconnect the web from the flanges of the girder, which poses significant concerns for load capacity especially at girder ends. This research studies shear strength loss in deteriorated steel multi-girder bridges by 3-D finite element models built in ABAQUS. Our analysis is focused on web area loss and web thinning due to corrosion, and their consequences for shear and web buckling capacity reduction. Area loss will be modeled by removing materials from the web, and web thinning will be simulated by reducing the web thickness. The numerical models resemble real steel corrosion forms by changing the shape, size and location of the area loss. A load rating method will be proposed based on the analyses.

Except for smooth pavement and low maintenance cost, IABs have also outperformed conventional seat-type abutment bridges in seismic performance due to increased redundancy, higher damping, and smaller displacements. However, lack of information on their seismic design and performance may have discouraged their use in high seismic zones. In this study, current research and implementation of IABs are comprehensively reviewed. IABs with steel-concrete girders provided by NYDOT are chosen for intensive seismic case study. Three-dimensional finite element models of IABs for nonlinear seismic analysis are elaborated to capture the behavior of components of superstructure, abutment stem, piles, backfill, etc. Pushover analyses are carried out to obtain the capacity curves. Through parametric studies, the effects of bearing are outlined. Conclusions and some recommendations are made for seismic evaluation and design practice of IABs.

High premium is placed by multinationals on maintenance and repair of oil and gas storage tanks. However, oil and gas storage tanks are subject to deterioration and degradation over time. Evaluation and monitoring of the conditions of oil and gas storage tanks will help to optimize their operation and reduce failures to an acceptable safety limit. This research studies the electrical behaviour of ultrasonic guided waves propagation in steel metal with defects. The ultrasound wave properties and characteristics are used to develop an Artificial Neural Network (ANN) Model that will predict the condition of oil and gas storage tank. Input parameters for the network will be derived from Ultrasonic Non-Destructive Testing (NDT) methods. The model is expected to help operators assess and predict the condition of existing oil and gas storage tanks and hence prioritize the planning of their inspection and rehabilitation.

The influence of the damage on the safety of the bridge must be judged right away. Yet it is not always an easy task, since the load-carrying capacity of a damaged girder has not been studied much. The first author has been involved in the evaluation of a steel girder overpass bridge damaged by collision. Based on the data obtained from this bridge, the load-carrying capacity of the deformed girder is investigated numerically in the present study. To be specific, the deformation of the main girder due to collision is reproduced by the finite element analysis and the deformed steel girder is loaded to evaluate the load-carrying capacity. The result indicates that as far as the damage is confined to the deformation of the girder, the collision does not threaten the safety of the bridge even when the deformation is quite large. © SDSS 2019 - International Colloquium on Stability and Ductility of Steel Structures.",,"Deformation; Ductility; Load limits; Loads (forces); Overpasses; Steel beams and girders; Steel structures; Collision damage; Steel girder; Disasters",,,,,,,,,,,,,,,,"(2008) User's Manual, , Dassault Systemes Simulia Corp.

These thermal stresses which can result from support restraints, debris accumulating in expansion joints, or from non-uniform thermal gradients, can lead to significant damage in the concrete deck. Conventional heat transfer theory in solids, in three-dimensional finite element formulation, is used to perform a sequentially coupled thermal-stress analysis in a selected single-span case study bridge. Actual environmental boundary conditions for a selected geographical region are used to develop the thermal profile. The vertical thermal gradient is shown to be largely non-linear as opposed to existing models, such as AASHTO. The thermally induced tensile stresses in the concrete are shown to be significant compared to service load stresses and constitute 60% of the tensile strength of the concrete deck.

When a bridge has to be built in an urban area, either it has to be a landmark or it should blend away in the environment. The use of curved steel panels is one option to obtain these requirements. However, due to a lack of knowledge, engineers end up with a conservative design to implement these structural elements. For that reason, a Finite Element Model is made of a railway bridge, where the outer webs of the main girders have a varying web curvature. Six different models are made and compared. The most important parameters that are compared are the deformations and the stresses in the webs. The study finds that curved webs have an equal or even better behavior than flat webs, even with smaller web thickness. This makes that designers can use curved webs in their design, without needing extra steel to make their design safe.

In the past two decades, there has been an increasing interest in this kind of structure in bridge engineering. In this paper, the parameterized modeling module CBCW (Composite Bridge with Corrugated Webs), which has been developed based on commercial software - ANSYS by its APDL and UIDL languages, is presented. Despite the complexity of prestressed concrete box-girder bridges with corrugated steel comparing to the conventional PC bridges, CBCW makes it easy and convenient for bridge designers to perform 3-D finite element analysis. The module has been applied in the simulation of the Juancheng Yellow River Highway Bridge of China, which is currently the longest composite bridge with corrugated steel webs worldwide. The interface and menu functions of the module were introduced at first. Then the application of the module was discussed in detail. The comparison between the FEA and measurement results is made, which yields a satisfactory accuracy. It turns out that it is feasible for bridge engineer to carry out FE analysis of this kind structure by CBCW. © Nottingham University Press","Composite bridge; Corrugated steel webs; Finite element analyses","Box girder bridges; Bridge decks; Composite bridges; Concrete beams and girders; Intelligent computing; Modeling languages; Prestressed concrete; Steel bridges; 3D-finite element analysis; Bridge engineering; Commercial software; Continuous box girders; Corrugated steel webs; Finite element simulations; Parameterized model; Prestressed concrete box girder; Finite element method",,,,,"National Natural Science Foundation of China, NSFC: 50908105","The research work is supported by the National Natural Science Foundation of China (No. 50908105).

Using cross-ties and dampers is one of the considerable countermeasures for vibration control. However, the mechanism and design method of cross-ties and dampers have not been established yet. This paper proposed to use the combination of cross-ties and dampers installed between the cross ties and the stay cables to increase both the natural frequencies and structural damping of the cables for suppressing vibrations. The numerical simulations on the cross-tied-stay cables system were carried out to evaluate the effectiveness of cross-ties. The FEM model is a half of one cable plane in the mid span of a long cable stay bridge with the mid span 1400 m, and includes 4 flexible type cross-ties with dampers. The simulation results showed that the effectiveness of cable dampers was improved when the stay cables were connected each other by the cross-ties; and the cross-tie dampers could effectively increase the cable damping. The damping evaluation equations for a taut cable with an arbitrary number of Kelvin dampers were derived. The formula was expected to be able to evaluate the damping of cross-ties-stay cable system in the further study. © Nottingham University Press","Cross-ties; Dampers; Long stay cable; Simulation; Vibration mitigation","Bridge cables; Damping; Intelligent computing; Vibration control; Cross-ties; Dampers; Simulation; Stay cable; Vibration mitigation; Cable stayed bridges",,,,,"50678123; National High-tech Research and Development Program: 2006AA11Z120","The authors would like to acknowledge the support of the National Nature Science Foundation of China (Grant No.: 50678123) and National High-tech R&D Program (863 Program Grant No.: 2006AA11Z120).",,,,,,,,,,"Bosch, H.R., Park, S.W., Effectiveness of external dampers and crossties in mitigation of stay cable vibrations (2005) Sixth International Symposium on Cable Dynamics; Caracoglia, L., Jones, N.P., In-plane dynamic behavior of cable networks.

During the structural analysis of cable-stayed bridges with large ratio of width-to-span under construction, some specific problems arise which are not common in other types of bridges. One of the problems is the influence of eccentric loading on the structural integrity of the bridge. This paper presents a finite element analysis for the systematic construction sequence simulation of cable-stayed bridges with a large ratio of width-to-span. The objective of this simulation is to evaluate the torsion-stiffness and short-term influences of the construction sequence on the structural integrity of the cable-stayed bridge with H-type and I-type python.

However, the time-dependent behaviour of construction materials such as concrete and steel cables also causes changes in structural characteristics. If these are not taken into account properly, false alarms may result. This paper presents a systematic and efficient method to study the effects of long-term time-dependent behaviour due to concrete creep, concrete shrinkage and cable relaxation on the dynamic properties of cable-stayed bridges. The finite element model of the cable-stayed bridge is built up with beam elements and proper cable elements considering their geometric nonlinearity and time-dependent effects. The long-term time-dependent analysis is carried out using an efficient single-step finite element method using the age-adjusted elasticity modulus and shrinkage-adjusted elasticity modulus for concrete, and the relaxation-adjusted elasticity modulus for steel cables. Then the dynamic properties of the bridge can be obtained by the subspace iteration method. The effects of long-term time-dependent behaviour including concrete creep, concrete shrinkage and cable relaxation on the dynamic properties of typical cable-stayed bridges are examined in detail. © Nottingham University Press","Cable-stayed bridges; FEM; Free vibration analysis; Single-step method; Time-dependent","Cable stayed bridges; Concretes; Creep; Deterioration; Elastic moduli; Elasticity; Finite element method; Intelligent computing; Iterative methods; Shrinkage; Structural health monitoring; Vibration analysis; Free-vibration analysis; Single-step method; Structural characteristics; Structural health monitoring systems; Subspace iteration method; Time dependent; Time-dependent analysis; Time-dependent behaviour; Cables",,,,,"HKU 7102/08E","The work described in this paper has been supported by the Research Grants Council (RGC) of the Hong Kong Special Administrative Region, China (RGC Project No. HKU 7102/08E).",,,,,,,,,,"Au, F.T.K., Cheng, Y.S., Cheung, Y.K., Effects of random road surface roughness and long-term deflection of prestressed concrete girder and cable-stayed bridges on impact due to moving vehicles (2001) Computers and Structures, 79, pp. 853-872; Au, F.T.K., Cheng, Y.S., Cheung, Y.K., Zheng, D.Y., On the determination of natural frequencies and mode shapes of cable-stayed bridges (2001) Applied Mathematical Modelling, 25, pp. 1099-1115; Au, F.T.K., Liu, C.H., Lee, P.K.K., Shrinkage analysis of reinforced concrete floors using shrinkage-adjusted elasticity modulus (2007) Computer and Concrete, 4, pp. 477-497; Au, F.T.K., Liu, C.H., Lee, P.K.K., Creep and shrinkage analysis of reinforced concrete frames by history-adjusted and shrinkage-adjusted elasticity moduli (2009) The Structural Design of Tall and Special Buildings, 18, pp. 13-35; Au, F.T.K., Si, X.T., Time-dependent analysis of frames taking into account creep, shrinkage and cable relaxation (2009) 7th International Conference on Tall Buildings 2009, , Hong Kong; (1993) CEB-FIP Model Code 1990, , COMITÉ EURO-INTERNATIONAL DU BÉTON, London, Thomas Telford; Cook, R.D., Malkus, D.S., Plesha, M.E., Witt, R.J., (2001) Concepts and Application of Finite Element Analysis, , New York, NY, Wiley; Curley, N.C., Shepherd, R., Analysis of concrete cable-stayed bridges for creep, shrinkage and relaxation effects (1996) Computer and Structures, 58, pp. 337-350; Ghali, A., Favre, R., Elbadry, M., (2002) Concrete Structures: Stresses and Deformations, , London, Spon Press; Magura, D.D., Sozen, M.A., Siess, C.P., A study of stress relaxation in prestressing reinforcement (1964) PCI Journal; McGuire, W., Gallagher, R.H., Ziemian, R.D., (2002) Matrix Structural Analysis, , New York, John Wiley; Sapountzakis, E.J., Katsikadelis, J.T., Creep and shrinkage effect on the dynamics of reinforced concrete slab-and-beam structures (2003) Journal of Sound and Vibration, 260, pp. 403-416; Si, X.T., Au, F.T.K., Su, R.K.L., Tsang, N.C.M., Time-dependent analysis of concrete bridges with creep, shrinkage and cable relaxation (2009) The Twelfth International Conference on Civil, Structural and Environmental Engineering Computing, , 2009, Funchal, Madeira, Portugal; Zienkiewicz, O.C., Taylor, R.L., (1989) The Finite Element Method, , London, McGraw-Hill",,"Tizani W.","AceCad Software;Acumen;Autodesk, Inc.;SOFiSTiK AG;Tekla International","Nottingham","17th International Workshop on Intelligent Computing in Engineering, EG-ICE 2010","30 June 2010 through 2 July 2010",,149385,,9781907284601,,,"English","EG-ICE - Int.

FEA with GQJS is conducted throughout the work of the construction control of Juancheng Yellow River Highway Bridge, which is an externally pre-stressed concrete continuous box-girder bridge with corrugated steel webs with the total length of 1460m and span arrangement of 70m+11*120m+70m. During the course of analysis, two element-modeling methods are adopted by GQJS. Firstly, the beam elements of concrete roof and floor as well as steel webs share common nodes, agreeing with the assumption of plane section (One-node Method for short). Secondly, the nodes of the concrete roof and floor element are independent relatively and the elements of corrugated steel webs connect with the elements of top and bottom concrete slab (Two-nodes Method for short), not agreeing with the assumption of plane section, and the relative displacement between top and bottom concrete slab nodes are controlled by the corrugated steel webs element. The modeling technique discussed in this paper has been used and verified in the construction control of the Juancheng Yellow River Highway Bridge. The results of construction control indicate that the two modeling methods are effective, which makes a reference for practical application. © Nottingham University Press","Construction control; Corrugated steel webs; Finite element analysis; GQJS","Box girder bridges; Bridge decks; Concrete slabs; Finite element method; Floors; Highway planning; Intelligent computing; Roofs; Steel bridges; Construction control; Construction monitoring and controls; Continuous box girders; Corrugated steel webs; GQJS; Highway bridge design; Modeling technique; Relative displacement; Highway bridges",,,,,"National Natural Science Foundation of China, NSFC: 50908105","The research work is supported by the National Natural Science Foundation of China (No. 50908105).

The approach aims at identifying structural characteristics during long-term structural health monitoring, i.e. when the bridge is open for traffic and weights and locations of currently passing vehicles are unknown. Thus, system and load properties have to be determined at the same time. The approach is based on the analysis of measured static responses, such as strains and deformations. To obtain further information for the identification of the loading, reaction forces need to be recorded additionally. The actual model-updating problem is solved by an optimization technique taken from the field of evolutionary algorithms. To evaluate the deformation behavior of concrete structures in detail, physical nonlinear finite element analyses are carried out. The approach is verified by conducting numerical simulations on two damaged reinforced concrete girders, which are loaded with a single force. © Nottingham University Press","Model adaptation; Model-updating; Structural health monitoring; System identification","Deformation; Identification (control systems); Intelligent computing; Reinforced concrete; Bridge superstructure; Model Adaptation; Model identification; Model updating; Non-linear finite-element analysis; Nonlinear model identification; Optimization techniques; Structural characteristics; Structural health monitoring",,,,,,,,,,,,,,,,"Cairns, J., Du, Y., Law, D., Structural performance of corrosion-damaged concrete beams (2008) Magazine of Concrete Research, 60 (5), pp. 359-370. , June; (1993) CEB-FIP Model Code 1990, , CEB-FIP, Comitée Euro-International du Béton; Cornelissen, H.A.W., Hordijk, D.A., Reinhardt, H.W., Experimental determination of crack softening characteristics of normalweight and lightweight concrete (1986) Heron, 31, p. 2; (2008) DIN 1045-1: Tragwerke Aus Beton, Stahlbeton und Spannbeton, Teil 1: Bemessung und Konstruktion, , DIN 1045-1, Deutsches Institut für Normung; He, R.S., Hwang, S.F., Damage detection by an adaptive real-parameter simulated annealing genetic algorithm (2006) Computers and Structures, 84, pp. 2231-2243; Hjelmstad, K.D., Shin, S., Damage detection and assessment of structures from static responses (1997) Journal of Engineering Mechanics, 123 (6), pp. 568-576; Hordijk, D.A., (1991) Local Approach to Fatigue of Concrete, , PhD thesis, Delft University of Technology; Huth, O., Czaderski, C., Hejll, A., Feltrin, G., Motavalli, M., Tendon Breakages Effect on Static and Modal Parameters of a Post-tensioned Concrete Girder (2005) SHMII-2'2005, pp. 847-853. , Shenzhen, China; Karczewski, B., Schnellenbach-Held, M., Model-updating in structural health monitoring: A novel genetic programming and neural networks approach (2009) 16th International EG-ICE Workshop, , 2009, Berlin, Germany; Koza, J.R., (1992) Genetic Programming: On the Programming of Computers by Means of Natural Selection, , Cambridge, MA: MIT Press; Pullmann, T., Schnellenbach-Held, M., Lubasch, P., GPcore - A generic framework for genetic programming (2007) 14th International EG-ICE Workshop, , Maribor, Slovenia; Thorenfeldt, E., Tomaszewicz, A., Jensen, J.J., Mechanical properties of high-strength concrete and applications in design (1987) Symposium on Utilization of High-Strength Concrete, , Stavanger, Norway; Terlaje, A.S., Truman, K.Z., Parameter identification and damage detection using structural optimization and static response data (2007) Advances in Structural Engineering, 10 (6), pp. 607-621; Unger, J.F., Teughels, A., De Roeck, G., System identification and damage detection of a prestressed concrete beam (2006) Journal of Structural Engineering, ASCE, 132 (11), pp. 1691-1698",,"Tizani W.","AceCad Software;Acumen;Autodesk, Inc.;SOFiSTiK AG;Tekla International","Nottingham","17th International Workshop on Intelligent Computing in Engineering, EG-ICE 2010","30 June 2010 through 2 July 2010",,149385,,9781907284601,,,"English","EG-ICE - Int.

Second, the weak position of the bridge under certain condition is determined through the application of the finite element analysis tool-ADINA. Finally, the geometry information of bridge model built by the modelling tool is introduced into the discrete element program-3DEC, which is used to stimulate the collapse process of the bridge.

The transformer operates at high switching frequency under unbalanced power flow conditions and contains parallel layers to handle high current. The main difficulty is to integrate high and low voltages respecting the insulation exigencies and keeping a small number of PCB’s with reduced thickness. Furthermore, the current sharing between parallel-connected layers is evaluated by using a new modified analytic method. This method is applied to different winding configurations and the results are validated by FEA (Finite Element Analysis) simulation. © VDE VERLAG GMBH · Berlin · Offenbach.",,"Electric load flow; Energy management; Intelligent robots; Power electronics; Printed circuit boards; Switching frequency; Winding; Analytic method; Bridge converter; High switching frequencies; Parallel-connected; Planar transformer; Unbalanced power flow; Vehicle applications; Winding configuration; Electric windings",,,,,,,,,,,,,,,,"Ma, H., Tan, Y., Du, L., Han, X., Ji, J., An integrated design of power converters for electric vehicles (2017) Proc.

The selected problem constitutes an actual research direction. The reinforcement of the Anchorage areas and the bister shaping as well as its work in connection to the adjacent concrete requires an advanced numerical analysis in particular when the blister houses two or more cable anchorages. The common design practice follows the use of the simplified formulas as well as reinforcement solutions for every Anchorage separately. Nevertheless under the set of several anchorages in the volume of one blister the stress fields overlap each other and in such circumstances the analysis should be carried out with the use of more advanced methods and tools. In the paper the morphology of the damages layout of one blister (cracks pattern) is presented together with the damages reasons. The anchorages area was modelled in the FEM software as a volume with the reinforcement. The numerical model was built with the use of the non-linear constitutive law for concrete (smeared cracks model) and steel. The concreto volume was represented by the finite elements of the type HEX8, reinforcement was described with the use of truss elements. In result of the analysis, maps of the principal tensile stress were obtained together with the cracks pattern, which followed the crack layout observed in the real structure. © 2019 by the fib.

The paper presents results of structural analysis of a reinforced concrete (RC) void slab bridge of which top 10 cm surface concrete is replaced with UHPFRC. Structural behaviour of the RC void slab bridge with and without UHPFRC on top of the deck is investigated by using three-dimensional nonlinear finite element method. It is understood that the UHPFRC layer reduces the mid-span sagging moment by redistributing load to the pier region and increasing the hogging moment over the pier.

The pier cap is designed to carry the heavy concentrated loads transmitted to the pier through elastomeric bearings. Unexpected vertical cracks were observed at service loads on the sides directly under the bearings. A site visit revealed that the elastomeric bearings were compressed on one side with loss of contact on the other. The crack width measurements showed a crack width as high as 1mm at some locations, where the cover provided was found to be 100 mm, which is more than the proposed cover of 50 mm. A detailed analysis using nonlinear finite element analysis (NLFEA) was performed to understand the causes of these cracks using two models: one with full contact of the bearings and the other with half contact. The complete crack pattern was obtained from NLFEA which showed cracking at a similar location as that at the site. The cracking occurred at a lower load in the model with half contact at bearings. This clearly established the reason for cracking as the reduced contact area at the bearings. The wide cracks were perhaps due to the unexpected high cover at the corner location. The safety of the structure at ultimate loads was also checked using NLFEA and strut-and-tie method, and is seen that the structure is safe at ultimate loads. © 2019 by the fib.

It has a total length of 606m and a maximum span length in the extradosed part of 188m. It was requested that the delay of the construction works was significantly recovered for 8 months in this project. A construction schedule of cantilever erection from P6 was a critical-path in total period. Then, the intermediate support on P6 was constructed on a temporary jetty adjacent to P6 at the same time as the pier head, and the intermediate support was moved onto the pier head of P6 by incremental launching method after completion of the pier head. Only a part of the intermediate support was constructed on the temporary jetty due to its heavy weight. That is, concrete of between a lower slab and a cross beam was placed after moving onto P6. The weight of the intermediate support was reduced to 15,000kN. However, because the intermediate support on launching was an unstable structure, its safety was confirmed with three-dimensional (3D) finite-element analysis(FEA) During launching, measurements such as horizontal movement, reaction force of vertical jack, coefficient of friction between rail for moving and jack, and vertical displacement of rail were monitored. The intermediate support was moved about 20m in 4 days. A construction period of intermediate support was recovered for about 2 months than the usual construction period. © 2019 by the fib.

Analytical formulations based on sectional analysis are sometimes too conservative to optimize a strategy for intervention on existing structures, therefore non-linear finite element analyses are used to exploit the maximum overall capacity of the members under investigation. For example, membrane actions developing in continuous slabs or bridge decks can be considered by using finite element analyses able to take into account for mechanical and geometrical nonlinearity. In particular, this work deals with the interaction between longitudinal bending moment and transverse shear strength of a reinforced concrete (RC) existing hollow-box bridge built in Switzerland. In the perspective of Level of Approximation Approach proposed by the Model Code 2010, the shear strengths of a bridge deck have been calculated by adopting Model Code 2010 formulations, Critical Shear Crack Theory (CSCT) and Non-Linear finite element analyses. NLFEA have been carried out with the ""PARC CL2.0 crack model"" implemented in the ABAQUS program at the University of Parma, using a multi-layered shell modeling in order to predict global and local failures. This numerical investigation highlights that, even for design purposes, the interaction between longitudinal hogging moment and transverse shear strength may be significant in the assessment of the shear resistance leading sometimes to non-conservative predictions. © 2019 by the fib.

However, the applicability of existing steel arches has certain limitations. To expand the application scope of steel arches and enhance the material utilization rate, this study proposed a calculation and analysis model for a novel steel arch with an adjustable axis. First, the finite element calculation model of the arch structure was established using the finite element software Midas Civil based on Timoshenko beam theory. Second, the sensitive factors that affect the mechanical response characteristics of the novel arch, such as the connection method of the upper chord in the arch section, boundary conditions of the arch springing hinge, and temperature, were thoroughly discussed through calculation and analysis of engineering projects. Finally, the effect of span and width on the arch stability was discussed using the linear elastic analysis method. The mechanical response of the new steel arch was obtained, and the reliability of the calculation results was verified. Results demonstrate that a rigid connection is applicable to the upper chord connection of the arch section, and the two-hinged arch applies to the frame. Temperature changes can lead to obvious deformation and the decrease in temperature indicates a clear stress on the arch. Without considering wind load, the minimum wide-span ratio for the novel arch reaches 1:20. This study can provide a reference for application and calculation analysis of such arches. © 2019 School of Science, IHU.","Adjustable steel arch; Finite element; Mechanical response; Wide-span ratio","Arches;

Before that, since Alberta transportation test level four (TL-4) bridge barriers design has never been experimentally tested with GFRP bars as reinforcement instead of steel, and to justify this replacement, three models of bridge barriers mimicking the design and detailing of Alberta Transportation TL-4 bridge barriers and representative of the as built conditions were put together and tested in VecTor2. These models were subjected to a displacement rate analysis until failure to evaluate their ultimate load-carrying capacities. After one of the models reinforced with GFRP reinforcement proved a comparable strength to its counterpart reinforced with steel, it was used as a reference model to evaluate the behavior of the models representing the repair techniques. In the proposed repair techniques, the new barrier wall is anchored to the existing bridge deck using single headed GFRP bars. This paper investigated the efficiency of the repair techniques in terms of ultimate load-carrying capacity and deflection, as well as the effect of different embedment lengths, and the different spacings of single-headed GFRP bars and different diameters on the ultimate load carrying capacity The data generated from this parametric study were compared and discussed, and some recommendations and conclusions were drawn. The next stage of this project will be to experimentally test and validate those models to verify the validity of using GFRP reinforcement in Alberta TL-4 bridge barriers instead of steel, and the efficacy of the proposed repair techniques. � 2019 Canadian Society for Civil Engineering.

Fabricating different bridge elements off-site has many benefits including higher material quality and durability, more efficiency in time and cost, increased safety of the work zone, less environmental impacts and decreased traffic disruptions. Currently, the Canadian Highway Bridge Design Code (CHBDC) specifies empirical equation for shear distribution factor in skew slab-on-girder bridges subjected to dead load with skew parameters less than a certain value. However, there is no information available in the literature to verify the use of such equations for the design of the fully-precast Canadian Precast Prestressed Concrete Institute (CPCI) girder bridges. However, skew bridges are necessary in some conditions such as crossing an obstacle or highway interchange. Since CHBDC load distribution factors were determined for general slab-on-girder bridges with limited value of skew parameters, a parametric study is required to investigate the applicability of these factors for precast bridge systems and bridges with higher values of skew parameters. In this study, a finite element modelling (FEM) was used to obtain load distribution factors for such bridges under self-weight and superimposed dead load and then correlate them with those available in CHBDC. The results indicated that the skew factor identified by CHBDC is not applicable for shear distribution at obtuse corner of this type of bridge with skew angle larger than 20 and also considering a modification factor for distribution of longitudinal moment among girders is essential between 45 and 60 skew angles. � 2019 Canadian Society for Civil Engineering.

In this paper, a method for the strength analysis of the bridge expansion joint is proposed based on computer simulation, and then the dynamic stress of the structure under vertical and horizontal wheel load is calculated. The strength of the expansion joint structure was examined by the pulsation strength criterion of the material under asymmetric cyclic loading. The results of computer simulation show that the largest dynamic stress of the expansion joint lies at the weld seam under the center beam, and this stress may exceed the pulsation strength of the material of the structure. This dangerous position from computer simulation is consistent with the damage position of the practical expansion joints in engineering. In order to overcome the possible damage, two methods are found to reduce the maximum stress in the expansion joint under the action of moving vehicle. The first method is to change the fullness of the weld seam in the expansion joint, and an optimized fullness can reduce the maximum stress of the structure to meet the strength requirement.

The failure of the concrete beam in fire is a hot issue for disaster prevention and mitigation in construction industry. In this paper, the system simulation is used to analyze the transient temperature of the concrete beam in fire based on the finite element method. The accuracy of the simulation results are verified by fire experiment. Furthermore, the prestress loss of steel bars inside the concrete beam is predicted based on the theory of high temperature creep by using the data of transient temperature field. The results of the transient temperature analysis show that the internal temperature of the reinforced concrete beam changes much longer than the fire duration, so that a longer time is required in the system simulation. The temperature inside the concrete beam is smaller than the temperature outside in the fire, which means that the concrete has a good protection effect on the internal structure such as steel bars. After the fire, the prestressed steel bars inside the concrete beam show a large prestress loss, which lead to a decrease in the bearing capacity and performance of the beam. Therefore, in order to predict the fire resistance performance and post-disaster service performance of prestressed concrete structures, the system simulation should be carried out for fire temperature, concrete beam temperature and prestress loss of the steel bar. © 2019, Computers and Industrial Engineering.

However, the applicable span length is only 20 m to 25 m because the maximum web height is about 900 mm. To extend the span length a new steel/concrete composite bridge was developed using the steel rolled H-beam. The new bridge form has continuous-span steel H-girders which are composite with the RC slabs to resist positive bending moments at span-center. Experiments were conducted with the partial bridge model, showing that a new SRC structural form has high bending strength and good ductile property. FEM model was developed to simulate the experiments, showing that displacements and strains obtained by FEM agreed well with test results. A design was conducted with a highway bridge model with a maximum span length of 50 m, showing that the proposed bridge satisfied the required safety and serviceability.

Typical steel structures are bridges, transmission line towers, and conveyersupporting frames. As corrosion-related problems and accidents have been frequently reported in recent years, the need for identifying the health condition of structures has increased. In this context, the axial compressive strength of corroded steel shapes is investigated with experiments and non-linear finite element analyses. The results indicate that the behavior of the corroded members depends strongly on the degree of corrosion and shows global flexural buckling, local buckling, section yielding, and combined failure modes.

Due to complex geometrical properties of curved girders, the prestressed concrete curved box girders are more complicated than straight bridges. Hence, more researches have been conducted for the purpose of determining a clear and good understanding of mechanical properties and behaviors of the curved bridges. The current study has also based on the engineering backgrounds of designed prestressed concrete curved box girders in order to investigate mechanical properties by modifying structural parameters when curved bridges are only subjected to static loads. Based on the performance of finite element analysis, the static analysis of different bridges with variable parameters has been carried out in order to compare mechanical properties of prestressed concrete curved box girders.

However, steel tub girders possess a relatively low torsional stiffness during construction due to the thin-walled open section that is susceptible to stability issues. Top flange lateral bracing, in the form of a horizontal truss, is installed along the entire length of the steel tub girder to increase the torsional stiffness of the girder. Internal K-frames are placed to control cross-sectional distortion.

The viaduct is a typical quasi-periodic structure with, even at low frequencies, a high modal density. This leads to difficulties in distinguishing between these clustered modes in modal identification as well as the pairing of experimental and numerically predicted mode shapes infinite element model updating. Alternatively, for periodic structures, use can be made for structural identification of the so-called free wave characteristics. A model updating method based on free wave characteristics has recently been proposed for periodic structures. In this work, this method is applied to the K032 viaduct. Vibrational measurements were first conducted on the viaduct to identify the free wave characteristics. Next, the discrepancy be¬ tween the calculated and identified free wave characteristics is minimized to update the finite element model ofthe viaduct. The model updating results are validated by comparing the mea¬ sured frequency response functions and those calculated from the updated finite element model. © 2019 The authors.","Free wave characteristics; Model updating; Multi-span viaduct; Periodic structures","Bridges; Computational methods; Earthquake engineering; Engineering geology; Frequency response; Geophysics; Periodic structures; Structural dynamics; Frequency response functions; Infinite element; Modal identification; Model updating; Multi-spans; Quasi-periodic structures; Structural identification; Wave characteristics; Finite element method",,,,,"KU Leuven","The research presented in this paper has been performed within the framework of project OT/13/59 “Quantifying and reducing uncertainty in structural dynamics”, funded by the Research Council of KU Leuven.

LiABlock_3D analyses masonry structures under seismic lateral loads and automatically predict the potential failure modes of complex assemblages in terms of local and global collapse mechanisms. The numerical formulation is based on limit equilibrium analysis and mathematical programming is used to solve the contact problem. Masonry structures are represented as a collection of three-dimensional rigid blocks. Once the geometry of the construction has been generated (i.e. using different CAD tools or MATLAB® scripts for parametric analysis), the numerical model requires few parameters as input data, such as the unit weight of materials and the friction coefficient. Several loading conditions can be considered, assuming different loading axis and load distribution (uniform and/or concentrated loads can be applied). With respect to failure condition, LiABlock_3D considers no-tension, frictional contact interfaces with infinite compressive strength. Opening and sliding failure conditions are considered. In order to show the potentialities and limitations of the developed software, a comparison of the outputs provided by LiABlock_3D with those obtained by Finite Element Analysis is presented and discussed as well.

The design philosophy of dynamic resistant structures (such as bridges) requires the imposed energy to be dissipated in the hinges of the structure and let the remain elements with no damages.. The RH is a novel substructure that mitigates the imposed energy through the yielding of easily replaceable steel bars, thus offering rapid restoration times. It is designed to have recentering capabilities because several steel bars remain primarily elastic, so they return to their initial position. The investigated variables are the type of material, the roughness of the contact surface, the diameter of the bars and the type of connection between the different parts of the RH. Stress analysis of the obtained results occurred in a way to quantify the problem and discover the weak regions of the RH. Finally, detailed design suggestions for the RH are provided.

In particular, the paper is focused on FEM (Finite Element Model) analyses on three dimensional models that compute the flutter instability. Geometric non-linear flutter instability analyses were carried out using a research and design software program (TENSO), which enables nonlinear dynamic analysis of wind-structure interaction. All the bridge structure is modelled. In particular, the bridge deck model was simplified by a beam model located in the deck section’s center of gravity and two massless rigid links to simulate the connection of the deck to the hangers and cables. The cables are represented by rectilinear cables element. The critical flutter speed was estimated using quasi-static approximation of the unsteady wind loads calculated by aerodynamic coefficients (i.e. lift, drag and moment coefficients) estimated by aerodynamic forces (i.e. lift, drag and moment) directly measured by wind tunnel tests. The executed analyses are by dynamic step-by-step integration of the nonlinear three-dimensional structure with geometric nonlinearities. The global stiffness matrix is updated at each load step by assembly of the stiffness sub-matrices of the elements, updated to account for the strain found at the previous time step, taking into account the geometric nonlinearity of the structure. Firstly, the calculation provides for the static equilibrium of the structure under dead, gravity and construction loads by nonlinear static analysis. It was computed simultaneously using two methods: step-by-step incremental method and a “subsequent interaction” method with variable stiffness matrix (secant method). The secant method is a finite-difference approximation of the Newton-Raphson’s modified method for systems of nonlinear algebraic equations. The solution under gravity loads is subsequently used as the initial step of the dynamic wind load analysis. The Newmark-Beta method with Rayleigh damping is used for numerical integration of the dynamic equations. Wind loads on the bridge deck are time dependent and they are simulated by applying the aerodynamic coefficients as a function of the time-dependent angle of attack at a given mean wind speed U. Displacements and rotations of the bridge deck at progressively increasing values of U, are estimated. The velocity at incipient flutter is fixed when the reference deck vibration amplitude exceeds ±5°. Details of the analyses results and calculation are given for an example of suspended foot bridges. Vertical displacements () and rotations of the deck about the longitudinal bridge axis (x) in normalized format (i.e. upward deck displacements are positive and counterclockwise rotations are positive) are discussed. © 2019 The authors.","Flutter instability; Non-Linear analyses; Suspended bridge","Aerodynamic drag; Aerodynamic loads; Angle of attack; Bridge cables; Bridge decks; Computational methods; Control nonlinearities; Earthquake engineering; Engineering geology; Finite difference method; Flutter (aerodynamics); Geometry; Geophysics; Lift; Nonlinear analysis; Numerical methods; Rotation; Stability; Static analysis; Stiffness; Stiffness matrix; Structural dynamics; Wind stress; Wind tunnels; Counter clockwise rotation; FEM (finite element model); Finite difference approximations; Flutter instability; Geometrically non-linear analysis; Nonlinear algebraic equations; Quasistatic approximations; Three-dimensional structure; Nonlinear equations",,,,,,,,,,,,,,,,"Avossa, A.M., Di Giacinto, D., Malangone, P., Rizzo, F., Seismic retrofit of a multi-span prestressed concrete girder bridge with friction pendulum devices (2018) Shock Vib; Knudson, W.C., Recent advances in the field of long span tension structures (1991) Eng.

Alternatively, lean duplex stainless steel has recently gained significant interest for its high structural performance, similar corrosion resistance and lower cost compared to the austenitic steel grade. Hence, this paper presents nonlinear numerical simulations of rectangular outer lean duplex stainless steel (EN 1.4162) CFDST short columns under compression, based on the finite element (FE) method, The FE model and its validation were initially presented. Then, the effect of the key parameters that influence the behavior of these types of columns was introduced. Based on that model, the behavior and design of rectangular outer lean duplex stainless steel (EN 1.4162) CFDST short columns under compression were discussed. All classes of the outer rectangular hollow section according to the depth-to-thickness (D/t) ratios were considered. The results showed that the axial ultimate strength of rectangular CFDST short columns increased linearly by increasing the concrete compressive strength, while it does not influence when changing the hollow ratios. Finally, the axial capacities were compared with the available design methods, and recommendations were conducted for the design strength of this type of column. The presented design model, for calculation of the ultimate axial strength of rectangular CFDST short columns with external lean duplex stainless steel outer tubes, gave suitable conservative results if compared with the other literature model. © 2019 The authors.","Compressive strength; Concrete-filled double skin columns; Finite element analysis; Lean duplex stainless steel; Short columns; Ultimate axial strength","Bridges; Compressive strength; Computational methods; Concretes; Corrosion resistance; Earthquake engineering; Electric power transmission; Engineering geology; Finite element method; Geophysics; Numerical methods; Steel corrosion; Structural analysis; Structural dynamics; Tall buildings; Tubular steel structures; Axial strength; Concrete compressive strength; Double skin; Electricity transmission towers; Lean duplex stainless steel; Nonlinear numerical simulation; Rectangular hollow sections; Short column; Duplex stainless steel",,,,,,,,,,,,,,,,"Uy, B., Wright, H.D., Bradford, M.A., Combined axial and flexural strength of profiled composite walls, Structures & Buildings (2001) Proceedings of the Institution of Civil Engineers, pp. 129-139; Varma, A.H., Ricles, J.M., Sause, R., Lu, L.-W., Experimental behavior of high strength square concrete-filled steel tube beam-columns (2002) J.

The application creates a digital model of the analyzed structure automatically assembling the representative objects which constitute the bridge, such as decks or piers, and the mutual relationships that each object has with the others. Then, the application generates a sequence of nodes and beams, placed on a horizontal plane corresponding to the added planimetric layout and, given the bridge coordinates, defines the site reference seismic hazard. The obtained digital model allows to convert the structure individual components’ description into a useful and functional finite element model. After selecting a certain number of return periods corresponding to the reference seismic action, the application generates several spectrum-compatible accelerograms to perform nonlinear time history analysis. Nonlinear dynamic analyses are preferred to others to better detect the seismic behaviour of bridges whose vulnerability is herein evaluated through the definition of fragility curves. In case of partial level of knowledge, the finite element model cannot be defined. Hence, ad hoc simplified mechanic-based methodologies have been developed. Two levels of capacity for the seismic verification are considered: one regarding the functionality (damage limit state) and the other regarding the bridge safety (collapse limit state). These limit states, considered in the fragility curves derivation, essentially concern the piers’ deformation and resistance capacity (ductile and brittle failures) and the girders’ loss of support. © 2019 The authors.","Fragility curves; Railway bridges; Seismic vulnerability","Computational methods; Engineering geology; Engineering research; Finite element method; Piers; Railroad bridges; Railroads; Seismology; Structural dynamics; Fragility curves; Individual components; Nonlinear time history analysis; Railway bridges; Representative object; Resistance capacity; Seismic vulnerability; Vulnerability assessments; Earthquake engineering",,,,,,"This research has been funded by the project “783298 – INFRA-NAT – UCPM-2017-PP-AG - Increased Resilience of Critical Infrastructure to Natural and Human-Induced Hazards”, funded by DG-ECHO – European Union Civil Protection.",,,,,,,,,,"Akkar, S., Bommer, J.J., Empirical equations for the prediction of PGA, PGV, and spectral accelerations in Europe, the Mediterranean Region, and the Middle East (2010) Seismological Research Letters, 81, pp. 195-206; Borzi, B., Ceresa, P., Franchin, P., Noto, F., Calvi, G.M., Pinto, P.E., Seismic vulnerability of the Italian roadway bridge stock (2015) Earthquake Spectra, 31 (4), pp. 2137-2161. , November 2015; Calvi, G.M., A displacement-based approach for vulnerability evaluation of classes of buildings (1999) Journal of Earthquake Engineering, 3 (3), pp. 411-438; Calvi, G.M., Pinto, P.E., Franchin, P., Marnetto, R., The highway network in the area struck by the event (2010) Progettazione Sismica, 1. , IUSSPress, Pavia, Italy; Calvi, G.M., Pinto, P.E., Franchin, P., Seismic design practice in Italy (2013) Bridge Engineering Handbook, , Second Edition (W.-F.

In integral bridges, the omittance of joints and bearings leads to substantial soil-structure interaction, thus increasing the sensitivity of the dynamic behaviour of the bridge to the underlying and backfill soil characteristic. As a result, accurate identification of the natural frequencies can be a profound problem for integral bridges when encastre grounding or frequency-independent spring-damper system is utilized in the numerical model. Considering the current trend of infrastructure development, this situation can lead to the increase of the economic cost of infrastructure. In this article, steady-state dynamic assessment of phenomenon at hand is presented by utilizing hybrid method of an in-house BEM for describing the semi-infinite part of the geological region and the commercial FEM software, ABAQUS for modelling the finite part of the soil-structure system. The retained flexibility and versatility of FEM and the capability of satisfying the Sommerfeld’s radiation condition of BEM make it possible to approach the problem in a more realistic and accurate manner without losing practicality. The influences of the bridge geometry and the soil condition on the natural frequencies of the structure are investigated and comparison to the conventional results are presented. © 2019 The authors.","ABAQUS; Coupled BEM-FEM; Dynamic soil-structure interaction; Integral bridge; Natural frequency","ABAQUS; Boundary element method; Computational methods; Engineering geology; Finite element method; Geophysics; Natural frequencies; Soil structure interactions; Soils; Structural dynamics; Coupled BEM-FEM; Dynamic soil-structure interaction; Frequency independent; Infrastructure development; Integral bridges; Radiation condition; Soil characteristics; Soil structure system; Earthquake engineering",,,,,,,,,,,,,,,,"Achenbach, J., (2012) Wave Propagation in Elastic Solids, 16. , Elsevier; Dominguez, J., (1993) Boundary Elements in Dynamics, , Wit Press; Basnet, M.B., Aji, H.D.B., Wuttke, F., Dineva, P., Impedance function for a soil-tunnel system in poroelastic geomaterial by hybrid BEM-FEM simulations (2017) 15.

Traditionally, the assembly variation analysis of compliant structures is achieved by combining finite element analysis (FEA) and Monte Carlo simulation. Although the distribution of assembly dimensions can be obtained by such a process, the internal relationships between component deviations and assembly precisions are hidden in the reduplicative computational process. This study aims to shed light on the internal relationships between component deviations and assembly deformations of compliant mechanisms by Equilibrium Equations of Incremental Forces (EEIF). Dimensional deviation is an additional part to theoretical dimension, so does incremental force is to theoretical assembly load. EEIF is the bridge between dimensional deviations and incremental forces. This paper extends the application area of EEIF from compliant joints to compliant beams. The beginning of this paper reviews mainstream assembly variation analysis methods and the application of compliant mechanisms. Following is the basic conceptions about Equilibrium Equations of Incremental Forces. In the theory development part, compliant joints and compliant beams are discussed respectively. Precision of the method is verified by comparing it with an ADAMS/Flex model. Then, the output sensitivity coefficient matrix is used to conduct statistical assembly variation analysis for compliant mechanisms.

The finite element method is used to simulate the impact process between the vessel with raked bow and bridge pier. The influence of parameter on the structural response and impact force is discussed, including the impact velocity, angle, mass of vessel, and the shape of bridge. The relationship of collision force and energy of impact vessel is investigated. It is found that the collision energy shows a quadratic growth trend with the increase of vessel velocity.

The displacement of bridge superstructure is larger than that of substructure and soil layer, the vertical deformation of the bridge is mainly caused by the gravity of the bridge.

First, two finite element (FE) models of a suspension bridge and a main cable-inspection vehicle coupled system are established using MIDAS Civil software and ANSYS software, respectively. Second, the mean wind speed distribution characteristics at a bridge site are analyzed, and the wind field is simulated based on the spectral representation method (SRM). Third, a modal analysis and a wind-induced vibration response transient analysis of the suspension bridge FE model are completed. Fourth, the vibration characteristics of the inspection vehicle are analyzed by applying fluctuating wind conditions and main cable vibration displacements in the main cable-inspection vehicle coupled FE model. Finally, based on the ISO2631-1-1997 standard, a vehicle ride comfort evaluation is performed. The results of the suspension bridge FE modal analysis are in good accordance with those of the experimental modal test. The effects of the working height, number of nonworking compressing wheels, and number of nonworking driving wheels during driving are discussed. When the average wind speed is less than 13.3 m/s, the maximum total weighted root mean square acceleration (av) is 0.1646 m/s2 and the vehicle ride comfort level is classified as ""not uncomfortable."" This approach provides a foundation for the design and application of inspection vehicles. © 2019 Lu Zhang et al.",,"Automobile suspensions; Cables; Inspection; Modal analysis; Suspension bridges; Transient analysis;

The structure of the accelerometer was designed using a proof mass connected by four folded-beam springs, which are compliant to inertial displacement caused by attached acceleration in the two lateral directions. At the same time, the folded-beam springs enabled to suppress crosstalk which is caused by mechanical coupling from parasitic vibration modes. The differential capacitor sense structure was employed to eliminate common mode effects. The design of gap between comb fingers was also analyzed to find an optimal sensing comb electrode structure. The design of the accelerometer was carried out using the finite element analysis. The fabrication of the device was based on SOI-micromachining. The characteristics of the accelerometer have been investigated by a fully differential capacitive bridge interface using a sub-fF switched-capacitor integrator circuit. The sensitivities of the accelerometer in the two lateral directions were determined to be 6 and 5.5 fF/g, respectively. The cross-axis sensitivities of the accelerometer were less than 5%, which shows that the accelerometer can be used for measuring precisely acceleration in the two lateral directions. The accelerometer operates linearly in the range of investigated acceleration from 0 to 4g. © Universiti Malaysia Pahang, Malaysia","Comb capacitive-type accelerometer; Cross-axis sensitivity; Folded-beam spring;

By adopting design formulae, it is possible to evaluate the safety quantitatively without complicated processes. However, to adopt a formula from the design, the structure needs to satisfy the Navier hypothesis and other requirements. For these reasons, the authors carried out an examination of evaluation procedures to define the limit deterioration state of PC structures for adopting a design formula. By comparing evaluation results of a design formula and experimental results of an actual PC beam removed from service, and also nonlinear FEM analysis results, the study shows the limit deterioration state of PC structures for adopting a design formula for the evaluation of safety. © 20th Congress of IABSE, New York City 2019: The Evolving Metropolis - Report.

In the case of assessing performance of existing structures, model parameters need to be modified based on the actual behavior since the actual system often differs from the design due to some reasons. In this study, a FE model of an existing bridge is initially developed based on its three‐dimensional shape measured by laser scanning. The initial model parameters are automatically validated and modified by model updating. Model parameters such as sectional specifications of members, structural details, boundary condition and material properties are modified under optimization analysis by minimizing an objective function. The objective function is formulated as a combination of fitness on dynamic characteristics obtained by measurements and analysis. Estimations of dynamic characteristics generally fluctuate under the influence of the environment in service state. In this study, distribution of the series of estimated frequencies is assumed as a Kernel distribution and significant frequencies such as natural frequencies are classified based on the probability density of estimations. The method stably provides accurate characteristics of the bridge under several excitation states. © 20th Congress of IABSE, New York City 2019: The Evolving Metropolis - Report.

NLFEM simulation has been recently a well-established approach to the analysis of concrete structures since the response of the structure can be simulated quite realistically. In combination with fully probabilistic approaches, one can consider the randomness of input parameters such as material, technological and environmental characteristics that can have a direct impact on economic aspects during structural lifetime. However, guidelines fully describing NLFEM modeling of structures and safety formats are not available until now. In the framework of the European Project INTERREG Austria-Czech Republic “ATCZ190 SAFEBRIDGE”, a number of existing bridges are carefully selected to be studied and modeled with NLFEM on deterministic and stochastic levels based on the upcoming Austrian standard ON B4008-2. The assessment of structures will be described and documented in detail and the results will assist the development of a guideline. This guideline targets to help the engineering community perform accurate NLFEM analysis and to assist the structure's owners to check the accuracy of the assessment process. The current paper focuses on the presentation and discussion of statistical information about road and railway bridges provided by the main bridge operators in both countries. Moreover, the most commonly addressed structural characteristics of bridges within the program region are summarized and the further future steps of the project are briefly described. © 20th Congress of IABSE, New York City 2019: The Evolving Metropolis - Report.

During 2015 a great rain fall occurred in a desert zone, it is not prepared by this amount of water, producing soil and debris currents from the mountain to the sea (about 100 km). These phenomena produced an important damage in the infrastructure, specially focused on roads and bridges. The main damage detected was the collapse of the infrastructure (piers and abutment) and the unlinking between deck and piers. This paper presents a proposal methodology to assess the effect of these currents on bridges, using the case of study of the Chañaral Bridge, a multi-supported bridge, with four concrete girders, slab girder and two spans of 20 meters supported in two abutments and one concrete pier, over the Charañal River. A sensitive hydraulic analysis via FEM was carried out using non-Newtonian flows (high density) representing the real final topography-condition of the current. A FEM of the bridge was carried out too considering a NonLinear transient load. The inputs for model are the outputs from the hydraulic model in order to define the condition that produce the same collapse behavior showed after the real debris current. Finally, results of this methodology are discussed, providing a comprehensive methodology, step by step, in order to obtained similar results according to the 2015 event. © 20th Congress of IABSE, New York City 2019: The Evolving Metropolis - Report.

Given shear rarely governs, minimizing web thickness is desirable. However, web slenderness can enable shear buckling and fatigue problems. The traditional strategy is to use welded transverse stiffeners; yet transversely-stiffened girders are prone to fatigue cracks and difficult to fabricate at high slenderness ratios. Thus, AASHTO currently limits web slenderness to 150. Alternatively, corrugated web girders overcome these deficiencies but require robotic welding for the web-to-flange weld. Corrugated webs are also limited to small web thicknesses (6mm or less) and girder depths (less than 1.5m) given web forming limits. The authors propose an alternative web geometry, introducing low-frequency sinusoids (LFS) in the web along its length. The LFS web can be welded to the flanges using semi-automatic weld techniques currently employed by bridge fabricators. The reduced web curvature allows for a wider array of web forming techniques with much larger plate thicknesses. In a finite element study, web geometric properties such as sinusoidal frequency and amplitude are varied. Results demonstrate a significant increase in the elastic shear buckling load and ultimate strength using a wavelength equal to the depth of the girder. The results of this study show promise for improved girder durability paired with material efficiency, demonstrating that a web product with constant amplitude and wavelength could work for various girder depths up to 3m and above. © 20th Congress of IABSE, New York City 2019: The Evolving Metropolis - Report.

Material analysis reports have validated the existence of ASR activity in fine aggregates. The deck comprises a well reinforced hollow-core prestressed system, however longitudinal cracks penetrate to the interior of the hollow cores. The extent of damage is heavy considering that the laboratory values for free ASR expansion are below the threshold limits, suggesting that there may be underlying structural causes related to the response of the deck under traffic. Objective of the study is to interpret the reported damage, reproduce computationally the mechanics that led to the observed crack pattern and assess the residual structural capacity of the bridge. Detailed nonlinear finite element analysis is conducted to evaluate the structure and study the synergistic effects of structural demands, along with time-dependent phenomena and chemically induced expansion. The paper presents the numerical modeling and mechanistic evaluation of the findings through sensitivity analysis of various scenarios considered to reproduce the state of damage and to assess the effectiveness of various retrofitting strategies considered for bridge rehabilitation. © 20th Congress of IABSE, New York City 2019: The Evolving Metropolis - Report.

These deck types typically consist of a grillage of closed trapezoidal longitudinal stiffeners and transverse web stiffeners, welded to a deck plate. As a result, fatigue problems occur due to the extensive use of complex welded connections. Unfortunately, fatigue effects have often been overlooked during design, which was also the case for an important multiple span box girder viaduct in Belgium (1978). Due to a renovation program of the ring road around Brussels, the number of traffic lanes on the viaduct should be extended from three to four. As a result, questions have been raised about the current structural health of the OSD due to fatigue and future fatigue damage accumulation. Therefore, extensive FEM analyses have been performed, taking into account various parameters such as increased traffic volume and accompanying axle loads, historical positions of the heavy lanes, historical road pavements and their temperature-dependent load spreading effects. In conclusion, accurate fatigue damages have been determined for all fatigue details. Therefore, focused inspections and design solutions can be provided, resulting in a durable bridge management for the next 60 years. © 20th Congress of IABSE, New York City 2019: The Evolving Metropolis - Report.

Nonlinear finite element analysis can provide a tool to assess safety; a more realistic estimation of the existing safety can be obtained. Dutch Guidelines, based on scientific research, general consensus among peers, and a long-term experience with nonlinear analysis, allow for a reduction of model and user factors and improve the robustness of nonlinear finite element analyses. The 2017 version of the guidelines can be used for the finite element analysis of basic concrete structural elements like beams, girders and slabs, reinforced or prestressed. Existing structures, like box-girder structures, culverts and bridge decks with prestressed girders in composite structures can be analysed. The guidelines have been developed with a two-fold purpose. First, to advice analysts on nonlinear finite element analysis of reinforced and pre-stressed concrete structures. Second, to explain the choices made and to educate analysts, related to the responsibility of limiting model uncertainty. This paper contains an overview of the latest version of the guideline and its latest validation extensions. Most important impact is the extended operational lifetime of an existing reinforced concrete slab structure. © 20th Congress of IABSE, New York City 2019: The Evolving Metropolis - Report.

A well-known, though not commonly discussed, problem is the stiff bond behavior of the used adhesives. Their use leads to stress concentrations in the CFRP and concrete at the location of cracks and an uneven strain distribution of internal and external reinforcement. On that basis, the usage of such a strengthening technique for components subjected to dynamic loads is limited or almost impossible due to premature debonding of the CFRP. The present paper focuses on numerical analysis of reinforced concrete bending beams strengthened with CFRP using the finite element method. In our analysis we focus on contact modelling techniques. The effect of differing adhesives on the overall behavior of the strengthened beams and strain distribution of internal and external reinforcement is shown. Numerical investigations demonstrate the relevance of the used adhesive on the static and fatigue behavior of the strengthened component. Modified and optimized material properties of the adhesive lead to a strengthening system which is even capable of carrying dynamic loads. © 20th Congress of IABSE, New York City 2019: The Evolving Metropolis - Report.

Such laminates, in which the plies are not parallel to the outer surfaces are found in GFRP bridge deck panels. The technology is developed for the construction of robust GFRP panels useful in highly loaded structures such as bridges or lock gates. In civil structures, the drawback in traditional FRP sandwich structures has always been debonding of skin and core. Such a debonding problem may occur after unintentional impact, followed by fatigue loading. Through the concept of using overlapping Z-shaped and two-flanged web laminates, alternating with polyurethane foam cores, debonding is no longer possible in vacuum infused GFRP bridge deck panels. In such panels, the fibers in the upper and lower skins as well as in the vertical webs run in all directions, rendering a resin-dominated crack propagation impossible. As a result of the integration of core and skin reinforcement, a skin material is created in which the reinforcement is not parallel to the outer surfaces, but tiled. Based on experimental results and numerical simulations the relevance of tiled laminates for civil applications is demonstrated. © 20th Congress of IABSE, New York City 2019: The Evolving Metropolis - Report.

Due to the constraint between beam and track, the longitudinal forces are generated in the track, beam, and pier. This paper aims to compare the differences in rack-beam interaction between the Japanese code, the Eurocode and the Chinese code. Particularly the distinctions in track resistance models, braking forces, temperature loads, and vertical live loads. For example, the Chinese code and Eurocode use a nonlinear resistance model, but the Japanese code uses a constant resistance model. A representative bridge example is used to demonstrate the differences, where the finite element analysis is adopted. In the finite element analysis, nonlinear bars or constant bars are used to simulate the track resistance, beam elements with rigid links are used to simulate the bridge, and the mechanical model for the ballasted track was is established. Continuous simply- supported beam is assumed in the analysis. Based on the calculation results, it is found that the additional longitudinal stress, the relative displacement, and the reaction force caused by the temperature, vertical live loads, and braking force are higher as calculated by the Eurocode compared to the Chinese code and the Japanese code. © 20th Congress of IABSE, New York City 2019: The Evolving Metropolis - Report.

Such bridges have been fabricated and constructed and have generally performed well. Where issues have been encountered, they were primarily related to bridge construction and, quite often to the torsional behavior of the severely skewed bridge superstructure. Until recently, there have been few analysis and design guidelines available to the structural designer on the construction engineering of the skewed I-girder bridges. AASHTO [1] specifies that the contract documents should state the fit condition for which the cross frames are detailed for I-girder bridges. Recommendations are also provided for the estimation of the cross frame locked-in forces. This paper presents a case study in a fit-up analysis of multi-span skewed I-girder steel bridge using 3D finite element method modeling. Fit-up analysis was carried out to evaluate girder's web distortions, determine the cross-frames locked-in forces and compare them to the recent AASHTO's recommendations. The paper should provide designers with a more detailed understanding of a bridge's behavior in this condition as compared with the more generalized recommendations from AASHTO guidelines. © 20th Congress of IABSE, New York City 2019: The Evolving Metropolis - Report.

However, the component repaired by single stop-hole without any additional reinforcement is liable to crack again because of the drilling defects and new stress concentration region around the hole. In this paper, two kinds of strengthened stop-hole methods, the high strength bolt reinforced stop-hole method and the CFRP patched stop-hole method, were investigated and compared. Finite element analysis was conducted to predict the repair efficiency and investigate the optimal parameters of each method. A total of 12 fatigue damaged specimens were repaired by different ways and tested under fatigue loading subsequently. Experiment results indicate that the fatigue life of specimens repaired by stop-hole is more than 20 times that of the unrepaired specimens. The high strength bolt reinforced stop-hole and CFRP patched stop-hole can extend the fatigue life by 9 and 8 times respectively, compared with the single stop-hole method. Debonding has a decisive effect on the reinforcement effectiveness. In addition, all the three methods studied in this paper can only extend the crack initiation life of the cracked steel component, but can't affect the crack propagation life. © 20th Congress of IABSE, New York City 2019: The Evolving Metropolis - Report.

This kind of structural solution brings about challenging issues related to the design of such structures exposed to the combined action of aerodynamic forces and hydrodynamic forces. One of the major issues is the experimental validation of numerical models to simulate the structural dynamics, based on hybrid codes joining aero-elastic and hydro-elastic interactions. This paper presents a feasibility study of wind-tunnel aeroelastic tests, where the submerged part of the bridge is simulated by Hardware-In-the-Loop (HIL) technology: actuators simulates the motion of the floater due to the combined action of the hydrodynamic loads on the floater (numerically simulated in real time) and of the aerodynamic and inertial loads transmitted by the tower (measured by a 6-components dynamometer). A similar HIL testing device has been developed at POLIMI in the field of floating offshore wind turbines, and it is likely to be applied to long-span bridges, as a tool for the experimental validation of complex numerical hybrid approaches. The opportunities offered by this technology will be discussed in the paper, working out a numerical example where the full-scale response of a FEM of the full-bridge is simulated and then it is scaled in order to assess the feasibility of aeroelastic tests in wind tunnel, with a focus on the characteristics of the actuation system for the tower base: necessary of degrees of freedom, amplitude and bandwidth of motion and force. © 20th Congress of IABSE, New York City 2019: The Evolving Metropolis - Report.

A strength assessment of these bridges is required for accurately predicting their load and deformation capacities. This paper proposes a two-stage strength assessment methodology for deep cap beams based on a nonlinear finite element analysis. To validate the finite element modeling approach, five pier caps experimentally investigated in the literature were analyzed. Crack patterns, load-displacement response, failure modes, and governing critical members were investigated under near collapse conditions. The complete proposed methodology was employed on a case study involving five existing bridges located in Ohio and the predicted capacities were compared with the traditional sectional and strut-and-tie methods. The proposed methodology has the potential to reduce the number of bridges found overloaded using traditional methods, resulting in significant cost savings. © 20th Congress of IABSE, New York City 2019: The Evolving Metropolis - Report.

As one of popular methods, the dynamic finite element model update finds the optimal parameters for the finite element model closest to the measured modal frequencies and shapes by using error minimization procedures. In this study, we propose a new method to construct an inverse eigenvalue problem that can directly obtain the parameters of the finite element model from the measurement modal information by developing a deep neural network to solve the inverse eigenvalue problem quickly and accurately. The solution of the inverse eigenvalue problem is obtained by using the mode frequencies and shapes measured as the input of the network and using the corresponding model parameter as the output. As an application example of the developed method, the dynamic finite element model update of a suspension bridge for given response data is presented. Unlike the existing update method based on the optimization procedure, this method can be updated in real time, and various update solutions considering the measurement error can be easily obtained. © 20th Congress of IABSE, New York City 2019: The Evolving Metropolis - Report.

As part of this project we performed non-destructive testing of the P-T strands at select locations using ground penetrating radar and impact echo technology. After the detailed inspection, the bridges were load rated taking into account the deterioration noted and using a time dependent Finite Element Analysis. We re-calculated all stresses as “locked-in” during bridge erection. The ramp bridges were load rated for the current single lane configuration as well as a potential future two lane configuration. An overall load rating and condition report was prepared which evaluated various bridge repairs and strengthening options including the use of UHPC structural overlay. © 20th Congress of IABSE, New York City 2019: The Evolving Metropolis - Report.

However, the cable line shape of the suspension bridge compared with designed cable saddle have a deviation angle in the construction process. This condition resulted in cable cutting between the main cable and saddle, which was called the cable cutting phenomenon. The cable cutting phenomenon is unfavorable and difficult to avoid completely. To ensure safety, taking not only corresponding measurements of the cable structure in the construction process, but also optimizing the construction scheme to reduce the deflection angle between the cable and the saddle. In order to reduce the phenomenon of cable cutting in the construction process, this paper analyzes an example of the self-anchored suspension bridge with finite element calculation, adjusting of the suspender tensioning order, taking into account linear and cable forces, and optimizing the tension scheme. The result shows that the consideration of the cable cutting effect on the main cable is necessary for suspension bridges. Appropriate tensioning optimizing scheme can significantly eliminate the unfavorable condition of the main cable in system conversion process. © 2019 American Society of Civil Engineers.","Bridge Engineering; cable shape; Cutting cable optimization; finite element; Sling tension; Suspension Bridge","Construction; Finite element method; Suspension bridges; Bridge engineering; Cable shape; Construction process; Construction scheme; Conversion process; Deflection angles; Optimization scheme; Self-anchored suspension bridge; Cables",,,,,,,,,,,,,,,,"Hu, J.-H., (2006) Research on Structural System and Static-dynamic Performance of Long-span Self-anchored Suspension Bridges [D], , Changsha: Hunan University; (2002) Design Specification for Highway Suspension Bridge [S], , JTJ xxx; Li, C.-X., Wang, L., Liu, G.-D., Separate calculation method on suspension bridge saddle's position [J] (2005) China Journal of Highway and Transport, 18 (1), pp. 63-68; Liu, Z., Liu, H.-J., New arithmetic for cable deflection and gravity stiffness of suspension bridges [J] (2009) Engineering Mechanics, 26 (6), pp. 127-132; Lei, J.-Q., Zheng, M.-Z., Xu, G.-Y., (2002) Suspension Bridge Design [M], , Beijing: China Communications Press; Tang, M.-L., Shen, R.-L., Qiang, S.-Z., An accurate calculation method for erecting curves of wire strands of long suspension bridges [J] (2001) Journal of Southwest Jiaotong University, 36 (3), pp. 303-307; Wang, S.-R., Zhou, Z.-X., Gao, Y.-M., Newton-raphson algorithm for preoffsetting of cable saddle on suspension bridge [J] (2016) China Journal of Highway and Transport, 29 (1), pp. 82-88; Wang, X.-M., He, S.-H., Duan, R.-F., Hanger tensioning process analysis of self-anchored suspension bridge with spatial cables [J] (2016) Engineering Mechanics, 33 (10), pp. 164-172; Wei, J.-L., Study on calculation method of free cable shape for self-anchored suspension bridge [J] (2016) Journal of Highway and Transportation Research and Development, 33 (11), pp. 93-98; Yan, K., Shen, R.-L., Chen, W.-G., Influence of bending rigidity on geometric shape of main cable [J] (2011) Bridge Construction, 47 (1), pp. 22-25; Zhou, C.-D., Tan, Y.-G., Song, G.-B., (2004) The Installation of the Suspension Bridge Superstructure [M], , Beijing: China Communications Press",,"Wang L.Gong H.Huang B.","et al.;Joint USTB-Virginia Tech Lab on Multifunctional Materials;Research Institute of Highway;University of Science and Technology Beijing;University of Tennessee, Knoxville;Virginia Polytechnic University","American Society of Civil Engineers (ASCE)","Transportation Research Congress 2017: Sustainable, Smart, and Resilient Transportation, TRC 2017","23 May 2017 through 25 May 2017",,152434,,9780784482513,,,"English","Transp.

Influenced by the trend of road and river, the hollow core slab bridges are often skewed with rivers. So it is essential to study the span length and skew angle effects in bridge widening. Based on a highway widening project, some representative hollow core slab bridges are selected for widening analysis. Theoretical method and finite element method are used to analysis the LLDF of slab bridges before and after widening. Finite element method(FEM) can give high precision in LLDF calculating. The influences of span length, connecting stiffness and skew angle are studied. The result indicates that no matter before or after widening the LLDF become smaller with the increase of span length. After widening, the LLDF of the half slabs near to the widening seam reduce obviously and with the span length increases the variation becomes more obviously. The connecting stiffness brings small influence to the LLDF in hollow core slab bridges. And with the increase of skew angle, the LLDF of the new side slab changes obviously, but the variation of LLDF of original slabs is not obviously according to skew angle. © 2019 Trans Tech Publications, Switzerland.","Connecting stiffness; Hollow core slab bridges; Load distribution factors; Skew angle; Span length; Widening","Electric power plant loads; Finite element method; Highway bridges; Stiffness; Connecting stiffness; Hollow core slab; Load distribution factor; Skew angles; Span length; Widening (transportation arteries)",,,,,,,,,,,,,,,,"Guide for widening highway bridges, ACI 345.2R-13, American Concrete Institute, Michigan (2013) USA; Niwa, J., Fakhruddin, K.M., Etc.

Two methods that have been widely used for controlling the settlement are either reinforcing the abutment subsoil with geogrid or constructing the abutments on piles. This paper describes the application of a two-dimensional Finite-Element Method (FEM) by using Plaxis 2D V8.5 for comparing the performances of these two methods. The effect of the geogrid normal stiffness, length, and depth of reinforcement on the horizontal and vertical displacements of abutment is also investigated. Data from an instrumented bridge abutment have been used for the model verification. The reduction of the bridge abutment, the vertical settlement, and the horizontal displacement by pile and geogrid have been analysed and compared. It is found that constructing the abutment on piles has a better performance in reducing the vertical settlement of the bridge abutment. However, lower lateral displacement can be obtained by using a geogrid with higher normal stiffness. It is also found that while the vertical settlement is not affected by the geogrid stiffness, the horizontal displacement of the abutment decreases by increasing the stiffness. © 2019 Sharif University of Technology.

This paper will evaluate the reliability levels that are inherent in the simplified empirical equations in the AASHTO LRFD to design concrete slab bridges. Typical one-span, multilane, straight bridges, with various span lengths are modeled using finite element analysis (FEA) and subjected to AASHTO live loads. FEA results are compared with LRFD moments to quantify biases that might result from the simplifying assumptions in AASHTO. The reliability index β for bridge cases using AASHTO procedures and FEA results were quantified. The results of this analysis showed that current live load factors in AASHTO LRFD procedures were below the required levels of reliability index (β <3.5) for one-lane bridges, and those indices were higher for multilane bridges, yet did not reach the required level, thus proposing to increase the AASHTO live load factors. © 2019 - IOS Press and the authors.

Firstly, through the study of theoretical knowledge of structural model, the design of test model is carried out. Secondly, the node and unit number of test model are given to carry out theoretical calculation of model. Thirdly, the strain of arch rib is observed through model test to simulate the stress status of real bridge, and other accessory members are also mechanically tested. Finally, the measured data of arch ribs, suspenders and other components are compared with those of the bridge site. The results show that the geometric size of the model is much smaller than that of the real structure.

In this paper, FEM is used for modelling a bidirectional test on a 2.5m-diameter, 80m long bored pile at the Cao Lanh cable-stayed bridge in the Mekong Delta, Vietnam.

In particular, the deformation caused by shrinkage and creep of concrete is an important part of deflection that often exceeds expectations. To achieve creep deformation control, extending the curing time and postponing the loading age are frequently adopted during construction. This article proposed an approach based on creep experiments with prismatic and beam specimens and viscoelastic model-based finite element analyses to evaluate the effect of the concrete strength development factor on the ultimate creep coefficient in the Comité Euro-International du Béton-Fédération internationale de la précontrainte (CEB-FIP) model. The concrete strength development factor ξcc(t/tu) is defined as the ratio of the mean compressive strength at the loading time to the maximum mean compressive strength obtained in the test. The strategies for targeted regulation and control of ξcc(t/tu) were discussed by establishing an artificial neural networks model for strength prediction from a database provided in our previous work. Uniaxial compressive prismatic specimens and pure bending beam specimens with a span of 5.0 m were used in the experiment for creep behavior observation. A viscoelastic finite element analysis (FEA) model was established based on solidification theory. The FEA model results were verified with measured data for capturing the creep behavior under ambient conditions to obtain reliable long-term creep deformation predictions. Finally, the proposed method was validated with the Xincheng bridge construction for the optimistic loading age determination, and the results indicated good feasibility in girder deflection control.

However, during the concrete deck pour, the top flanges are in compression and the entire girder is susceptible to the failure mode of global lateral torsional buckling (LTB). Several incidents have occurred ranging from the excessive deformation to the complete bridge collapse. Usually a lateral truss system is installed at the top flange level to form a “pseudo-closed” section and to help resist LTB before concrete hardens. However, the installation of top lateral bracing along the entire girder span, albeit common in current practices, might not be efficient given the differential girder shear deformation distribution along the length. This paper presents a general approach for the topology optimization of the top lateral bracing configuration for the steel tub girder system. The optimization is formulated based on a modified genetic algorithm (GA) in conjunction of the 3D finite-element analysis implemented in Python-ANSYS APDL AAS coupling programming environment. The truss member number and connectivity are encoded in real-valued chromosomes and the objective function of the optimization is to minimize the total weight of the top lateral bracing system subjected to buckling constraints using the penalty function. Case studies are carried out and the optimized bracing configurations are compared with those from the previously-published studies. The results show that the proposed approach allows successful optimization of partial top lateral bracing system with improved efficiency and buckling resistance. The approach can also be used for the optimization of the lateral bracing of other long and slender girder systems. © Structural Stability Research Council Annual Stability Conference 2019, SSRC 2019.All right reserved.",,"Box girder bridges; Buckling; Chromosomes; Concretes; Flanges; Genetic algorithms; Shear flow; Stability; Topology; Trusses; 3D-finite element analysis; Bracing configuration; Buckling constraints; Buckling resistance; Deformation distributions; Lateral-torsional buckling; Modified genetic algorithms; Programming environment; Beams and girders",,,,,,,,,,,,,,,,"(2015) Version 14.5 Academic Research, General Purpose Finite Element Software, , ANSYS Canonsburg, PA; Battistini, A., Wang, W., Helwig, T., Engelhardt, M., Frank, K., Stiffness behavior of cross frames in steel bridge systems (2016) ASCE Journal of Bridge Engineering, 21 (6), p. 04016024; Balogh, T., Vigh, L.G., Genetic algorithm based optimization of regular steel building structures subjected to seismic effects (2012) Proceedings 15th World Conference on Earthquake Engineering, pp. 1-10. , Lisbon, Portugal; Han, L., Helwig, T.A., Effect of girder continuity and imperfections on system buckling of narrow i-girder systems (2016) Proceedings of Annual Stability Conference, , Orlando, Florida; Han, L., Helwig, T.A., Nonlinear behavior of global lateral buckling of I-girder systems (2017) Proceedings of Annual Stability Conference, , San Antonio, TX; Helwig, T.A., (1994) Lateral Bracing of Bridge Girders by Metal Deck Forms, , Ph.D. Dissertation University of Texas.

One method to achieve this goal is the introduction of shape memory alloys (SMAs) as a replacement of traditional steel reinforcements in concrete structures. SMAs exhibit a characteristic known as ""shape memory effect,"" which allows the recovery of large deformations through the alloy's martensite and austenite phase transformations. This effect gives SMAs an inherent advantage over steel. The purpose of this paper is to characterize the effect of an embedded SMA rod on a concrete system undergoing a thermal cycle, and to optimize the configuration of these materials. To achieve these ends, a system is modeled in Abaqus, a software suite for finite element analysis, consisting of a concrete block with an embedded, prestrained SMA rod, in which the concrete and SMA material properties have been determined from experimentation and secondary research. A set of the SMA's properties (max transformation strain, coefficient of thermal expansion, stress influence coefficients, and volume fraction of SMA to concrete) are iteratively altered to produce characterization of the rod's effect on the system, and then the same set are again altered using a multi-objective optimization tool to minimize deflection and maximize the temperature where concrete damage occurs. This approach is a cost-effective method to characterize the effects of these material properties and produce results that can be utilized in future projects where SMAs are deployed in large-scale concrete structures. © 2019 SPIE.

Hence accelerated bridge construction is most essential to society. It is possible mainly by adopting precast superstructures. Adjacent precast, prestressed multi-beam bridges will avoid any in-situ constructions. However, there is a possibility of the longitudinal crack along the joint between girders if the transverse connection is poor. Thereby the integrity between girders is lost. This is due to the lack of shear friction effect. The improvement over this problem is investigated by developing Finite Element models using ABAQUS software.

In construction projects aesthetic and form is habitually crucial for the architect while structural designers aim for efficiency and stability of the structure. This research is concerned with the design of an urban footbridge located in Tehran-Iran with social and cultural spaces in which the form of the bridge is obtained by the use of topology optimization process. The objective of this study is to investigate the utilization of topology optimization process in architecture in order to achieve a beneficial design framework for both architectural and structural engineers. As first step, site analysis, connectivity and access diagrams and physical planning of the project is presented to provide the planar schematization of the project, along with a brief review associated with application of topology optimization process and its applications in architecture. Further on, primary planar design of the bridge is introduced as input to a general purpose Finite Element Analysis software, subject to stress analysis for various combinations of boundary conditions such as bridge supports and loading regions. Structural form-finding algorithm is then used to obtain the 3-dimentional structurally optimized chassis of the bridge. Algorithms used in this research are based on Evolutionary Structural Optimization (ESO) with objective functions to either minimization of volume and consequently weight of the structure while maximization its stiffness. Following several variations and comparison of altering forms and with regard to architectural requirements of the project, the more appropriate forms were chosen. In addition to architectural and structural efficiency, these forms are optimized with respect to both structural volume and consumable material to have the maximum stiffness. As topology optimization method is a solution for form development based on structural efficiency, an effective relation could be built between structure and architecture. In recent years, this method is introduced to the field of architecture and possesses capacities for more development in the close future. Furthermore, this paper describes the design steps of an architectural space through topology optimization method to whom interested in this field of study. And by investigating the effect of different approaches of ISO algorithms and varying input parameters better understanding of topology optimization processes is achievable for those interested in implementing these techniques within their schematic architectural design process.","Evolutionary Structural Optimization; Form-Finding; Structural Shematic Design; Topology Optimization",,,,,,,,,,,,,,,,,"(2010), McKinsey Global Institute Report; Population reference Bureau-World population data sheet (2011) United Nations; (2011) Cities and Climate Change,Global Report on Human Settlements, , London,Washington DC; Hansen, J., Ruedy, R., Sato, M., Imhoff, M., Lawrence, W., Easterling, D., Peterson, T., Karl, T., A closer look at United States and global surface temperature change (2001) Journal of Geophysical Research, 106, pp. 239-247; Akbari, H., Pomerantz, M., Taha, H., Cool surfaces and shade trees to reduce energy use and improve air quality in urban areas (2001) Solar Energy, 70 (3), pp. 295-310. , no: pp; Kotharkar, R., Surawar, M., (2015) ""Land Use, Land Cover, and Population Density Impact on the Formation of Canopy Urban Heat Islands through Traverse Survey in the Nagpur Urban Area,"" Journal of Urban Planning and Development, ASCE, 2015, Vol. 142(1); Badrinath, K.V.S., Studies of Urban Heat Island using ENVISAT AATSR data (2005) Journal of the Indian Society of Remote Sensing, 33, pp. 495-501. , pp; Patki, P.N., Alange, P.R., Study of influence of land cover on urban heat island using remote sensing (2009) IOSR Journal of Mechanical & Civil Engineering, pp. 39-43. , pp; Ramachandra, T.V., Kumar, U., (2010) Greater Bangalore: Emerging Urban Heat Island, , Geospatial application papers; Katpatal, Y.B., Kute, A., Satapathy, D.R., Surface-and Air-Temperature Studies in Relation to Land Use/ Land Cover of Nagpur Urban Area Using Landsat 5 TM Data (2008) Journal of Urban Planning and Development, pp. 110-118. , pp; Gopalkrishnan, S., Krishna, R., Sharan, M., Some signatures of Urban heat patches in Southern India (2003) Proc Indian Natn Sci Acad, 69, pp. 603-614. , pp; (2006) NDP, Nagpur Development Plan Report; (2008) VHS, Vidarbha Heritage Society Report; Akbari, H., Pomerantz, M., Taha, H., Cool surfaces and shade trees to reduce energy use and improve air quality in urban areas (2001) Solar Energy, 70 (3), pp. 295-310. , no: pp; Lowry, W.P., Empirical estimation of urban effects on climate: A problem analysis (1977) Journal of Applied Meteorology, 16, pp. 129-135. , pp; (2004) Mannual on National Land Use/ Land Cover Mapping on 1:250,000 Scale Using Multi-Temporal IRS P6-AWIFS Data, , NRSA, Dept. of Space, Govt. of India, Balanagar, Hydrabad; Janetos, A.C., Justice, C.O., Land cover and global productivity: A measurement strategy for the NASA programme (2000) International Journal of Remote Sensing, 21, pp. 1491-1512. , pp; Sudhakar, S., Rao, K., Land use and Land cover analysis-Remote sensing application, National Remote Sensing Centre report, ISRO, Chapter 2, pp. 21-4Cracknell, A.P., Synergy in remote sensing-What's in a pixel?

The dominant shear action is represented here by the concentrated load due to the wheel contact pressure. The missing model for the shear distribution in case of a concentrated load became the major motivation for an experimental campaign and afterwards for a non-linear analysis of this phenomenon. Together 12 slabs were tested in Laboratory with concentrated load and the obtained results were used for calibration of the non-linear model. The non-linear Finite Element (FE) analysis was carried out using the ATENA software.

A detecting device is developed consisting of a bilaterally constrained beam equipped with a piezoelectric polyvinylidene fluoride (PVDF) transducer. Under thermally induced displacement, the bilaterally confined beam is buckled. The post-buckling response is deployed to convert low-rate and low-frequency excitations into high-rate motions. The attached PVDF transducer harvests the induced energy and converts it to electrical signals, which are later used to measure the thermal limits. The efficiency of the proposed method was verified through a numerical study on a prestressed concrete bridge. To this aim, finite element simulations were conducted to obtain the thermally induced deformation of the bridge members between the deck and girder. In addition, an experimental study was carried out on a 3D printed measuring device to simulate the thermal loading of bridge. In this phase, the correlation between the electrical signals generated by the PVDF film and the corresponding deck-girder displacement was investigated. Based on the results, the proposed method effectively measures the mechanical response of concrete bridges under thermal loading. © 2019 SPIE.","experiment; finite element (FE) modelling; piezoelectricity; Prestressed concrete bridge girder; structural health monitoring (SHM); thermal response","3D printers; Concrete beams and girders; Concrete bridges; Crystallography; Deformation; Experiments; Finite element method; Fluorine compounds; Numerical methods; Piezoelectricity; Prestressed concrete; Thermal load; Transducers; Finite element simulations; Harvesting energies; Mechanical response; Polyvinylidene fluorides; Postbuckling response; Structural health monitoring (SHM); Thermal response; Thermally induced deformations; Structural health monitoring",,,,,"Zhejiang University, ZJU","This study is supported by the Startup Foundation of the Hundred Talents Program at the Zhejiang University.",,,,,,,,,,"Roy, M., Ray, I., Davalos, J.F., High-performance fiber-reinforced concrete: Development and evaluation as a repairing material (2013) J.

However, studies on the mechanism of a steel box and precast concrete slab connected by a shear key remain scarce. To explore the mutual coupling relationship between the steel box girder and the prefabricated bridge deck slab under a shear key, an experimental model of shear connection between steel box and precast concrete slab was proposed in this work. Finite element analysis and experimental methods were used to develop a push-out test analysis model with 12 symmetrical Ushaped shear keys in three rows and two columns along the longitudinal direction of a precast slab. Using the plastic damage model, the mechanical response characteristics of the shear connection structure, including its force transmission mechanism, stress state, and strain distribution, were analyzed and the accuracy of the calculation results was verified. Results indicate that as the amount of load increases, the compressive stress of the concrete slab expands from the root of the shear key in an arched manner and eventually forms an elliptical table. The load on a single shear key is inversely proportional to its distance from the loading point. The crack load of the concrete slab is 0.47 Pu, and the yield load of the shear key is 0.7 Pu. This study offers a certain reference value for optimizing the design of bridges with a steel- concrete composite girder. © 2019 Eastern Macedonia and Thrace Institute of Technology.","Finite element; Mechanical response; Shear key; Steel-concrete composite beam","Box girder bridges; Bridge decks; Composite beams and girders; Concrete slabs; Finite element method; Loads (forces); Precast concrete; Experimental modeling; Longitudinal direction; Mechanical response; Mechanical response characteristics; Plastic-damage models; Shear key; Steel concrete composite beam; Steel-concrete composite girders; Structural design",,,,,,,,,,,,,,,,"Faxing, D., Ming, N., Yongzhi, G., Zhiwu, Y., Zheng, Z., Linchao, Z., Experimental study on the slip performance of stud shear connectors and calculation of shear capacity (2014) Journal of Building Structures, 35 (9), pp. 98-106; Zhaofei, L., Yuqing, L., Peak Slip and Shear-Slip Constitutive Relationship of Welded Joints (2014) Journal of Tongji University(Natural Science), 42 (7), pp. 1006-1010; Chen, Y.T., Zhao, Y., West, J.S., 'Behaviour of steel-precast composite girders with through-bolt shear connectors under static loading' (2014) Journal of Constructional Steel Research, 103, pp. 168-178; (2017) 'Steel Structure Design Specification: GB50017-2017', pp. 132-133. , Beijing: China Planning Press, China; Chengjun, L., Zhixiang, Z., Ci, S., Liang, F., Experimental study on prefabricated combined shear nails (2015) Bridge Construction, 45 (5), pp. 60-65; Xu, C., Sugiura, K., 'Analytical investigation on failure development of group studs shear connector in push-out specimen under biaxial load action' (2014) Engineering Failure Analysis, 37, pp. 75-85; Chengjun, L., Zhixiang, Z., Yayi, H., Liang, F., Study on Shear Capacity of Assembled Composite Beam Shear Studs (2017) Journal of Chinese Highway Society, 30 (3), pp. 264-270; Jie, K., (2017) 'Research on shear resistance of high strength bolts used to join steel-concrete composites', pp. 23-26. , Master thesis of Southeast University, China; Shim, C.S., Chang, S.P., Cracking of continuous composite beams with precast decks (2003) Journal of Constructional Steel Research, 59 (2), pp. 201-214; Liang, F., Xiao, L., Rongqiang, D., Study on Shear Test of Shear Force Group of Steel Box-Concrete Combination Structure with Hole Stiffener Ribs (2017) Science Technology and Engineering, 17 (14), pp. 256-261; Lin, Z., Liu, Y., He, J., 'Behavior of stud connectors under combined shear and tension loads' (2014) Engineering structures, 81, pp. 362-376; Xu, C., Sugiura, K., Masuya, H., "" Experimental study on the biaxial loading effect on group stud shear connectors of steelconcrete composite bridges"" (2014) Journal of bridge engineering, 20 (10); Bing, Z., Xuewei, W., Experimental study on PBL shear bond of steel-mixed composite girder bridge considering transverse prestress effect (2016) Journal of Southwest Jiaotong University, 51 (4), pp. 621-631; Shim, C.S., Lee, P.G., Yoon, T.Y., Static behavior of large stud shear connectors (2004) Engineering structures, 26 (12), pp. 1853-1860; Shanpo, T., Study on calculation method of shear connectors for steel-mixed composite beams (2014) Journal of Railway Engineering Society, 31 (8), pp. 56-61; Kuhlmann, U., Breuninger, U., 'Behaviour of horizontally lying studs with longitudinal shear force' (2002) In: Composite Construction in Steel and Concrete IV, pp. 438-449. , Banff, Canada: ASCE; Veljkovic, M., Johansson, B., 'Residual static resistance of welded stud shear connectors' (2006) In: Composite Construction in Steel and Concrete V, pp. 524-533. , Berg-en-Dal, South Africa: ASCE; Qingtian, S., Yu, L., Study on Shear Capacity of High Strength Mortar Group Nail Connections (2015) Journal of Tongji University(Natural Science), 43 (5), pp. 699-705; Topkaya, C., Yura, J.A., Williamson, E.B., Composite shear stud strength at early concrete ages (2004) Journal of Structural Engineering, 130 (6), pp. 952-960; Aimin, Y., Jundong, F., Leike, C., Rongwei, L., Shear performance test of shear bond of precast bridge joints (2018) China Journal of Highway and Transport, 31 (12), pp. 81-87; Wenzhao, S., (2017) 'Research on ultimate limit state and ultimate bearing capacity of embedded pbl shear bond', pp. 55-59. , Master thesis of Southwest Jiaotong University, China; Sen, Y., (2018) 'Experimental and theoretical study on shear behavior of frp profile-concrete composite beams', pp. 78-81. , Master thesis of Zhengzhou University, China; Classen, M., 'Limitations on the use of partial shear connection in composite beams with steel T-sections and uniformly spaced rib shear connectors' (2018) Journal of Constructional Steel Research, 142, pp. 99-112; Lowe, D., Das, R., Clifton, C., 'Clifton C.

Concrete structures designed for a certain load and a certain reference period, following a certain code have to be re-examined because of changes in and around the structures. The vehicle movements are changing in maximum (axle) load and/or frequency. The reference period has passed and daily use and environmental loading (corrosion, cracks) has had its impact. The loading is changed and the code is more restricted on its design formulae. For the Dutch Ministry of Infrastructure, DIANA FEA BV has made an application to assess a large amount of concrete bridge structures in an automatic way and with limited man-hour impact. The application reads data imported directly from a database file of the owner. In this file, the full geometry is defined as is the reinforcement and the supports. In addition, loads and driving lanes are defined in the database according to the codes or the actual lanes present. The application is reading the data and setting up the finite element model. Although DIANA can be used for nonlinear analysis, first a linear design calculation is performed. Based on the input of static and movable loads along the lanes, a loading generator makes all the load (combinations). The linear analyses are run, envelopes are made and consistent spreading and shifting of moments and shear forces are taken into account. The main development that has been made is an engineering flowchart for adding the correct loads on the model and governing output items for the several envelope checks. For each (integration) point in the model, a spread in the correct direction and with the correct width is constructed. This is different for the bending moments and for the shear forces. Finally, all the moments and shear forces are checked against the cross section capacities. The paper describes the flowchart, process and generation of the model. Including the performance of code checking. © Federation Internationale du Beton (fib) - International Federation for Structural Concrete, 2019.","Concrete; Design; DIANAFEA; Infra; Nonlinear; Slab","Bridges; Codes (symbols); Concretes; Corrosion; Design; Flowcharting; Loading; Loads (forces); Nonlinear analysis; Concrete bridge structures; DIANAFEA; Environmental loadings; Infra; Nonlinear; Section capacity; Slab; Vehicle movements; Structural design",,,,,,,,,,,,,,,,"(2018) DIANA FEA, , https://dianafea.com/DIANA-Tutorials, https://www.researchgate.net/project/GettingDIANA-FEA-TNO-DIANA-even-more-easy-to-use; (2004) Eurocode 2: Design of Concrete Structures – Part 1-1: General Rules and Rules for Buildings, , EN 1992-1-1; (2013) Fib Model Code for Concrete Structures 2010, , FIB Fédération Internationale du Béton (fib), Lausanne, Switzerland; Hendriks, M.A.N., De Boer, A., Belletti, B., (2017) Guidelines for Nonlinear Finite Element Analysis of Concrete Structures, , Report RTD 1016-1:2017.

The numerical model was then validated by a successful prediction of the failure modes, ultimate shear capacity, and load-deflection behavior of all the specimens in a previous experimental study. Furthermore, different configurations of steel plates and anchor bolts were used to conduct a parametric study. Larger steel plate depth, thickness, concrete strength and denser anchor bolt spacing along the beam is significant to increase the ultimate shear capacity, stiffness and ductility of BSP beams. The ultimate shear capacity increases slightly with the increase of row number of anchor bolts, the bolt diameter and the yield strength of steel plates. BSP beams exhibit more ultimate shear capacity, stiffness and ductility as the shear span ratio decreases. The present study provides some new insights into the complex working mechanisms of BSP beams, and useful guidance to the realistic application of the BSP strengthening method in RC structures. © Federation Internationale du Beton (fib) - International Federation for Structural Concrete, 2019.","BSP; Finite element method; RC; Shear capacity; Strengthening","Bolts; Bridge decks; Concrete beams and girders; Ductility; Finite element method; Numerical models; Plates (structural components); Reinforced concrete; Stiffness; Strengthening (metal); Concrete strength; Load deflection behavior; Realistic applications; Reinforced concrete beams; Shear capacity; Strengthening methods; Ultimate shear capacities; Working mechanisms; Anchor bolts",,,,,"National Natural Science Foundation of China, NSFC: 51778496, 51778497","The research described here received financial support from the National Natural Science Foundation of China (Project No. 51778496 and No. 51778497).",,,,,,,,,,"Barnes, R.A., Baglin, P.S., Mays, G.C., External steel plate systems for the shear strengthening of reinforced concrete beams (2001) Engineering Structures, 23 (9), pp. 1162-1176; Barsanescu, P.D., Comanici, A.M., Von Mises, hypothesis revised (2017) Acta Mechanica, 228 (2), pp. 433-446; Chen, J.F., Teng, J.G., Shear capacity of FRP-strengthened RC beams: FRP debonding (2003) Construction & Building Materials, 17 (1), pp. 27-41; Dai, J.G., Gao, W.Y., Teng, J.G., Bond-slip model for FRP laminates externally bonded to concrete at elevated temperature (2013) Journal of Composites for Construction, 17 (2), pp. 217-228; Lu, X., Xie, L., Guan, H., A shear wall element for nonlinear seismic analysis of super-tall buildings using OpenSees (2015) Finite Elements in Analysis & Design, 98 (100), pp. 14-25; Li, L.Z., Jiang, C.J., Su, R.K.L., Lo, S.H., A piecewise linear transverse shear transfer model for bolted side-plated beams (2017) Structural Engineering Mechanics, 62 (4), pp. 443-453; Li, L.Z., Cai, Z.W., Lu, Z.D., Zhang, X.L., Shear performance of bolted side-plated reinforced concrete beams (2017) Engineering Structures, 144 (8), pp. 73-87; Mckenna, F.T., (1997) Object-Oriented Finite Element Programming: Frameworks for Analysis, Algorithms and Parallel Computing, , University of California, Berkeley; Wang, C.H., Foliente, G.C., Sivaselvan, M.V., Hysteretic models for deteriorating inelastic structures (2000) Journal of Engineering Mechanics, 127 (11), pp. 633-640","Li, L.; College of Civil Engineering, China; email: lilingzhi@tongji.edu.cn","Derkowski W.Krajewski P.Gwozdziewicz P.Pantak M.Hojdys L.","BASF's Construction Chemicals","International Federation for Structural Concrete","fib Symposium 2019:  Concrete - Innovations in Materials, Design and Structures","27 May 2019 through 29 May 2019",,147831,,9782940643004,,,"English","Proc. fib Symp.: Concr. - Innov.

Governments and infrastructure owners around the world face many challenges with such assessments because concrete structures which are designed for a certain load and reference period using a certain code, have to be reevaluated for structural safety considering changes in and around the structure. These changes may arise in traffic flow, the magnitude and frequency of the axle loads, environmental impacts or damage like cracks and corrosion, all of which influence the residual load carrying capacity. Accounting for these changes solely based of codes may not always be a straightforward task.

GFRP-reinforced concrete beam specimens of equivalent geometry were produced and tested under symmetrical two-point loading configuration. Deformation and cracking behaviour were monitored during the test, and the curvature was determined from the measured deformation response over the pure bending zone. In view of the lower stiffness of GFRP bars compared to conventional steel bars, the effectiveness of adding steel fibres to increase the flexural stiffness is investigated. Experimental results show that the steel fibres could reduce the average crack width and deflections of the beam, and could lead to a more ductile failure mode. The beam specimen was numerically analysed by employing the nonlinear finite element programme ATENA, and the analytical results are in good agreement with the experimental results. © 2019 IABSE.

These structures have to be preserved and technical works are usually essential to ensure its correct preservation. In this respect, it is common to use the finite element method as a numerical technique to assess the structural behaviour of this type of structure. However, when it comes time to face a historical construction, it is well known the high level of uncertainty surrounding the definition of the parameters that characterize it. Material properties, connections between structural parts or construction process are aspects that can cause significant changes between the classical numerical results and those experimentally identified. Among non-destructive techniques, finite element modal updating allows for adjusting the numerical model on the basis of dynamic characterization of the structure. This study presents the implementation of this process on the bridge of Posadas (Cordoba, Spain), a historic construction designed by the famous engineer Eduardo Torroja in 1957. The singularity of this historical construction lies in its special configuration, a concrete deck with inverted bowstring steel trusses, which can only be found in two other examples in Europe. © 2019 IABSE.

The Xuño Bridge, a single-span stone arch bridge located in Galicia (Spain) is considered as a case study. This structure presents the particularity that after hundreds of years, all its constructive elements have disappeared except the arch barrel. Thus, the typical scattering in the thickness of this element can be measured and quantified. For that purpose, an in-situ terrestrial laser scanner survey was conducted, acquiring its exact geometry. An uncertainty analysis, considering geometrical and material parameters, was then conducted with the aim of estimating the impact of the uncertainty sources in the prediction of the collapse load of the arch. Two different numerical modeling strategies were employed, the limit analysis approach and the finite element method. A sensitivity analysis was finally performed to identify the critical parameters on the response of the structure. © 2019 IABSE.

One of the main goals of this paper is the identification of the foremost causes of failure due to human errors in design and construction procedures. Therefore, a bridge failure database that includes several failure cases and a human errors survey will be used to support this line of work. After the identification of some explicit human errors that is believed to be the source of several reinforced concrete bridges failures, a selective analysis using risk indicators, namely, the probability of occurrence and consequence, is performed to choose those that might represent a higher risk for the structural safety. The outcome of five selected human errors in a specific case study is quantified using a robustness index, computed according to the variation of the structure reliability index due to the damages caused by human errors, allowing to demonstrate their impact in the structural safety. The modelling process and the finite element analysis of the structure is performed using TNO DIANA software, allowing the calculation of the reliability index of the structure damaged by different human errors. Within the COST action TU-1406, the main goal of this work is a contribution for the establishment of a roadways bridge quality control plan with higher efficiency in the reduction of bridge failures, their mortality rates and economic loss. © 2019 IABSE.

Several parameters to be taken into account in numerical analyses, such as the cut-off frequency, train speed or damping coefficients, might have a preponderant effect in the success of that validation. Therefore, this paper discusses and evaluates the effect of these parameters in the numerical analyses to be carried out on a FE model of the Alcácer do Sal railway viaduct, under the passage of an Alfa Pendular train with a speed equal to 220 km/h. The dynamic behaviour of the deck slab is evaluated, through a methodology that considers train-bridge interaction, taking into account frequency limits equal to 15, 20 and 30 Hz, small variations in the train speed and two different scenarios of damping coefficients. © 2019 IABSE.

The large scale of the Bridge increases the spatial mechanical features, making it imperative to employ a specific study on the construction process. Firstly, the auxiliary structures established for the construction as well as the construction scheme are introduced. Then FEA analysis is conducted to obtain the stress states and deflections of the girder and the launching nose in different construction scenarios. Based on the analysis results, component advancement suggestions are proposed. The incremental launching system in which different types of data are collected and fed back is introduced. By the construction data feedback system, the launching synchronization and expected girder position are ensured to enhance the construction safety.

First, a finite element model of a steel-concrete composite girderwas established by adopting the shell elements and spring elements, inwhich the spring element stiffness of group studs came from analytical results of the studied push out test specimens in terms of parameters of group studs arrangement. The values gained by FEM model were good agreement with the test values of the small box girder and confirmed that the numerical method is reasonable and right. The steel-concrete composite girder bridge has powerful recovery capability under elastic loading. It also showed that the connecting the steel girder with concrete plate by using the group studs in the accelerated construction steel-concrete composite small box girder bridges was completely feasible. Secondly, accelerated construction steel-concrete composite small box girder bridges, composed of five small box girders, with 40 m standard span, 39.2 m computing span and 16 m width, were analyzed by the same numerical method. Under completely shear state in the normal service condition, the total stiffness of the group studs gradually increases with the increase of the transverse force effect on composite girder bridge, but it has little influence on the stresses and deflections in the key section of the steel-concrete composite small box girder bridge. But the stress and deflection of the steel-concrete composite small box girder bridge increases slightly with the decrease of shear connection when the design of the composite bridge no longer satisfied the complete shear conditions. © 2019 Taylor & Francis Group, London.",,"Bridge decks; Composite beams and girders; Concrete testing; Concretes; Finite element method; Life cycle; Microalloyed steel; Numerical methods; Shear flow; Steel bridges; Steel testing; Stiffness; Studs (fasteners); Studs (structural members); Accelerated constructions; Analytical results; Composite girder bridges; Influence analysis; Recovery capabilities; Service conditions; Steel-concrete composite; Steel-concrete composite girders; Box girder bridges",,,,,"Cyrus Tang Foundation, CTF; Zhejiang University, ZJU; Fundamental Research Funds for the Central Universities","This work is financially supported by the Fundamental Research Funds for the Central Universities of China (2018 Zhejiang University) and the Cyrus Tang foundation of China.",,,,,,,,,,"Badie, S.S., Girgis, A., Tadros, M.K., Relaxingthe stud spacing limit for full-depth precast concretedeck panels supported on steel girders (2010) Journal of Bridgeengineering, 15 (5), pp. 482-492; Badie, S.S., Girgis, A., Tadros, M., Fullscaletesting for composite slab/beam systems made withextended stud spacing (2011) Journal of Bridge Engineering, 16 (5), pp. 653-661; Huang, C., Zhang, Z., Zhen, Z., Force Characteristics and failure Mechanism ExperimentalStudy of Group-nail in Steel-concrete CompositeStructure (2015) Journal of Wuhan University of Technology, 37 (2), pp. 100-105. , (in Chinese); Chen, X., Kunitomo, S., Chong, W., Qingtian, S., Parametrical static analysis on group studs with typicalpush-out tests (2012) J.

Therefore, there are a variety of options that should be considered and analysed. This work focuses on a specific type of dental restoration, the adhesive dental bridges. Adhesive dental bridges, also known as Maryland bridges, can be an alternative solution to conventional bridges or even implants, but it must guarantee the mechanical resistance of the bridge, to obtain a long and functional replacement. The main objective of this work was to study the effect of different resin-cements and the use of a two-retainer design or a single-retainer design on the mechanical resistance of an adhesive dental bridge. Three numerical methods were used: Finite Element Method (FEM), Radial Point Interpolation Method (RPIM) and Natural Neighbour Radial Point Interpolation Method (NNRPIM). The results showed that the connectors are the weakest areas because this is the area with highest stress concentration. The single-retainer design increases the risk of debonding.

The objective of this article is to test if the abutments teeth can support the resin-bonded bridge, used in dental reconstructions. The study was conducted on a 3D model of a part of maxilla where a tooth was missing. This model was developed through CT scans of an unknown patient. It was used the Finite Element Method (FEM) to study and analyse the results obtained. FEM is a technique that gives the solution of a complex mechanical problem through the discretization of the problem domain into multiple subdomains, called finite elements. Therefore, a complex problem is simplified by splinting the problem domain into smaller and simpler domains. The simple equations that model these finite elements are then assembled into a larger system of equations that models the entire problem. In the analysed case, the stresses measured were not sufficient to damage the abutments teeth that are responsible for supporting the bridge. The resin-bonded bridges appear to be a valid method of dental reconstruction since it does not damage the original teeth of the patient. © 2019 Taylor & Francis Group, London.",,"3D modeling; Adhesives; Computerized tomography; Ground supports; Resins; Complex problems; Discretizations; Mechanical problems; Problem domain; Sub-domains; Support structures; System of equations; Finite element method",,,,,"Fundação para a Ciência e a Tecnologia, FCT: MIT-EXPL/ISF/0084/2017; Federación Española de Enfermedades Raras, FEDER: NORTE-01-0145-FEDER-000022; Ministério da Ciência, Tecnologia e Ensino Superior, MCTES; European Regional Development Fund, ERDF","The authors truly acknowledge the funding provided by Ministério da Ciência, Tecnologia e Ensino Superior—Fundação para a Ciência e a Tecnologia (Portugal) by project funding MIT-EXPL/ISF/0084/2017.

The bridge is a flexible steel corrugated sheet surrounded by carefully compacted backfill soil. The numerical analysis is performed using the finite element program PLAXIS 2D, and the results are then compared to the typically used Swedish design method (SDM). This analysis focuses on the Skivarpsån composite bridge case study in Sweden. The analysis compares the recorded field measurements of straining actions and vertical deflections with the SDM design approach predictions and numerical model results. Then, the paper investigates the use of arching inducement techniques to reduce straining actions on the steel body without compromising the serviceability of the roads above. Embedding layers of a deformable material such as Pneusol causes significant decrease in the straining actions in the steel sheet. Two patterns are suggested herein, which decreases the developed straining actions from 10% to 15%. © 2019 American Society of Civil Engineers.","arching effect; finite element modeling; Flexible culvert; Pneusol; straining actions","Composite bridges; Geotechnical engineering; Numerical methods; Predictive analytics; Risk assessment; Soils; Steel bridges; Arching effects; Deformable material; Finite element programs; Numerical investigations; Pneusol; Steel composite bridges; straining actions; Vertical deflections; Finite element method",,,,,,,,,,,,,,,,"Akl, S.A.Y., Metwally, K.G., Optimizing arching creation for AbouMuharik tunnel in Egypt using numerical analysis (2017) KSCE Journal of Civil Engineering, 21 (1), pp. 160-167; Duncan, J.M., (1978) Soil-culvert Interaction Method for Design of Metal Culverts, Transportation Research Record 678, , Transportation Research Board, Washington, D.C.

The study presents a method to create continuity by casting a continuity diaphragm over supports and then post-tensioning the top end of the girders. The method exhibits all the advantages of a continuously post-tensioned technique. In the study, a bridge with three continuous spans was tested by using different truck loads at different positions. Stress on the girders and diaphragm were monitored by using the attached and impeded strain gages and a rosette. A three-dimensional finite element model was developed by using ANSYS and validated for the tested bridge. The FE model was used to analyze the transfer of stress between adjacent girders and spans. The results of FE model analysis indicated a strong correlation with the live load test data. Additionally, the results of the parametric study indicated that post-tensioning for continuity decreases the positive moments in the girders and leads to an increase in the transfer of stress between adjacent spans. It is expected that the results of the study will provide baseline data for these types of bridges. © 2018 - IOS Press and the authors.","Bridge; continuous girder; finite-element analysis; live load test; post-tension","Beams and girders; Bridges; Corrosion prevention; Corrosion protection; Diaphragms; Leakage (fluid); Load testing; Continuous girders; Live loads; Post-tension; Prestressed girder; Simply supported bridge; Strong correlation; Three dimensional finite element model; Transfer of stress; Finite element method",,,,,,"This study was sponsored and fully funded by the Inner Mongolia Transportation Department.",,,,,,,,,,"Kaar, P.H., Kriz, L.B., Hognestad, E., (1960) Precast-prestressed Concrete Bridges: 1, , Pilot tests of continuous girders: Portland Cement Association, Research and Development Laboratories; Kaar, P.H., Mattock, A.H., Precast-prestressed concrete bridges, 4. shear tests of continuous girders (1961) Portland Cement Association, Research and Development Laboratories, 3 (1), pp. 19-46; Saleh, M.A., Einea, A., Tadros, M.K., Creating continuity in precast girder bridges (1995) Concrete International, 17 (8), pp. 27-32; Thippeswamy, H.K., Ganga Rao, H.V., Franco, J.M., Performance evaluation of jointless bridges (2002) Journal of Bridge Engineering, 7 (5), pp. 276-289; Alampalli, S., Yannotti, A., In-service performance of integral bridges and jointless decks (1998) Transportation Research Record: Journal of the Transportation Research Board, (1624), pp. 1-7; El-Safty, A., Okeil, A.M., Extending the service life of bridges using continuous decks (2008) PCI Journal, 53 (6), pp. 96-111; Hossain, T., Okeil, A.M., Cai, C.S., Field test and finite-element modeling of a three-span continuous-girder bridge (2014) Journal of Performance of Constructed Facilities, 28 (1), pp. 136-148; Mattock, A.H., Kaar, P.H., Precast-prestressed concrete bridges: 3.

Both dental structures were subjected to the same masticatory loading (Corono-apical, Linguo-buccal and Disto- mesial). Three-dimensional finite element models of dental structures were developed to determine the stress distribution under simulated applied loads. In this study the biomechanical behavior of prosthetics dental crowns subjected to static loads in contact with the jawbone has been highlighted. Biomechanical simulations indicated that the equivalent stresses in the dental bridge are greater than that produced in the dental prosthesis.

Summing all of the distribution factors for all girders produces a number of design lanes greater than the bridge can physically carry. This research aims to assess the LLDFs suggested by the American Association of State Highway and Transportation Officials (AASHTO) specifications for steel-concrete composite girders bridge. A bridge consisting of four steel plate girders, 1650 mm depth; 33,950 mm span; and connected by shear connectors to a reinforced concrete deck, was investigated experimentally and numerically in this work. Eight trucks of 248 kN each were used with different arrangements to achieve the static test and to obtain the maximum design live load and deflection values for all girders. In addition, a finite element (FE) analysis was implemented for the bridge by using ANSYS. Comparisons among the numerical results and the available measured deflections showed a close agreement. The responses of the bridge, measured during the static test and the FE analysis, was used to assess the LLDFs presented by AASHTO. In addition, the proposed FE model was used to assess the LLDFs for shear and the effect of Cross-Frame Diaphragms (CFDs) on the LLDFs for composite steel girder bridges. The significance of the CFDs to distribute live loads among the girders was confirmed by increasing the LLDFs for exterior girders and decreasing the LLDFs for internal girders. © The Society for Experimental Mechanics, Inc. 2019.","AASHTO; Finite element; Live load distribution factors; Static load testing; Steel-concrete composite bridges","Automobile testing; Composite bridges; Electric power plant loads; Finite element method; Load testing; Reinforced concrete; Shear flow; Structural dynamics; AASHTO; Distribution factor; Live loads; Reinforced concrete decks; Static load testing; Steel plate girders; Steel-concrete composite bridges; Steel-concrete composite girders; Concrete beams and girders",,,,,,,,,,,,,,,,"Zokaie, T., AASHTO-LRFD live load distribution specifications (2000) J.

In this study, an evaluation of the LLDFs, suggested by the American Association of State Highway and Transportation Officials (AASHTO) specifications, for a pre-stressed reinforced concrete (RC) bridge was presented. A bridge consisting of five pre-cast pre-stressed RC girders was investigated experimentally and numerically using three cases of loading to obtain the maximum design live load and deflection values for all girders. In addition, a finite element (FE) analysis was implemented for the bridge by using ANSYS. Comparisons among the FE results and the available measured deflections showed a good agreement. The responses of the bridge, measured during the static loading test and the FE analysis, was used to evaluate the LLDFs presented by AASHTO. In addition, the FE results were used to evaluate the effect of Cross-Frame Diaphragms (CFD) on the LLDFs for pre-stressed RC bridges.

However, the perceived unwanted characteristics, such as the brittleness of glass may make it unsuitable, if used for a load-bearing structural member. But, using a toughened and laminated glass panel as the primary structural member can be practical because this toughened glass has a higher failure strength and is considerably safer when compared to ordinary glass. This paper began with an architectural drawing of a glass footbridge. Each primary beam of the footbridge was made from a large-sized glass panel. The bridge was modeled using beam finite elements and analysed using the finite element program, SAP 2000. The model was initially formed in 2D and analysed using two different support conditions. The analysis was repeated for a 3D model. The results of maximum moments, shear forces and deflections produced using both the 2D and 3D models and also using different support conditions are compared. The maximum stress was calculated and checked with the failure strength of toughened glass. The maximum deflection was also checked with the limiting value given in standard codes of practice. Connectors have been designed to connect the glass sub-panels together which have been used to form the large size glass panels, namely, the primary beams. The connectors have been designed and the stress level in the connection checked. Modal analyses using 2D and 3D models were also carried out to give frequencies and mode shapes of the footbridge under vibration. The frequencies are checked against the minimum value required according to standard codes of practice. All of the above checks were found to satisfy the relevant design criteria, and consequently the footbridge is now considered to be safe and ready for construction. © Springer Nature Singapore Pte Ltd. 2019.","Finite element; Glass footbridge; SAP2000","3D modeling; Architectural design; Finite element method; Footbridges; Fracture mechanics; Modal analysis; Structural members; Vibration analysis; Beam finite elements; Design criteria; Failure strength; Finite element programs; Maximum deflection; Sap2000; Support conditions; Toughened glass; Glass",,,,,"Ministry of Higher Education, Malaysia, MOHE; University of Surrey; Universiti Teknologi MARA, UiTM","Acknowledgements The authors would like to thank the Universiti Teknologi Mara, the Ministry of Higher Education, Malaysia (MOHE) for the funding of the paper and appreciatively acknowledge the University of Surrey for their academician expertise.",,,,,,,,,,"Nijsse, R., (2002) Glass in Structures, , Birkhäuser, Berlin; Smith, J.W., (1998) Vibration of Structures: Applications in Civil Engineering Design, , Chapman and Hall, Bristol; Maguire, J.R., Wyatt, T.A., (2002) ICE Design and Practice: Dynamics: An Introduction for Civil and Structural Engineers, , 2nd edn.

Torsional load results in the less efficient hollow section that plays an important role in hollow members. This load is generated on the members by an external load. The torsional load in hollow members that are reinforced longitudinally with FRP has been discussed for years. However, research on high-strength concrete (HSC) reinforced with glass fibre-reinforced polymer (GFRP) is scarce. Therefore, in this study, the behaviour of hollow beam internally reinforced with GFRP bars under cyclic load is investigated. For this purpose, the HSC-reinforced concrete hollow beam with GFRP bars and hollow beam with normal reinforcement are considered and finite element model is developed and nonlinear dynamic analysis has been conducted by applying cyclic loads to the developed models. In addition, reinforced concrete (RC) solid beam with HSC material is tested experimentally in order to verify and validate the ability of finite element software to predict the result. The analysis results are investigated in terms of the hysteresis loop, stress and strain distribution in the beam and it is indicated that the performance of hollow beam reinforced with GFRP bars and stirrups has improved in comparison with HSC beam with GFRP bars and also HSC beam with normal steel reinforcement. Therefore, based on this research, it is recommended to implement GFRP bars and stirrup for strengthening the concrete members in the high humidity areas where use of normal steel is not feasible due to corrosion threat. © Springer Nature Singapore Pte Ltd. 2019.","Cyclic load; Finite element; Glass fibre-reinforced polymer bars; High-strength concrete; Hollow beam","Atmospheric corrosion; Bridge decks; Concrete beams and girders; Cyclic loads; Fiber reinforced plastics; Finite element method; Glass fibers; High performance concrete; Nonlinear analysis; Polymers; Software testing; Steel corrosion; Structural loads; Supersonic aerodynamics; Tensile strength; Fibre reinforced polymers; Finite element software; Glass fibre reinforced polymer (GFRP) bars; Glass fibre reinforced polymers; High strength concretes; Hollow beams; Steel reinforcements; Stress and strain distribution; Reinforced concrete",,,,,,,,,,,,,,,,"(2014) Standard Version 6.13-4. the ABAQUS Software is a Product of Dassault Systèmes, , Simulia Corp, Hibbitt Karlsson & Sorensen Inc, USA; (2005) Building Code Requirements for Structural Concrete and Commentary (ACI, , ACI, Farmington Hill, Michigan; Bernardo, L., Lopes, S., Plastic analysis and twist capacity of high-strength concrete hollow beams under pure torsion (2013) Eng.

Certain geographical situation demands skew supports in addition to the curved layout of the bridge and results in complex skew-curve geometry of the deck. The present study focuses on predicting the support reaction response for each unique skew-curve combination of four-cell box-girder bridges via 3D finite element analysis. Central curvature angle for the bridges considered in this paper has been varied from 48° curving left to 48° curving right, at an interval of 12° while the skew angle is swept from 0° to 50° at an interval of 10° to generate feasible combinations possible for skew-curve case. For these unique simply supported multicell concrete box girder bridges, support reactions for dead load as well as for Class-A and Class-70R vehicular live load cases are monitored via large parametric study. Results indicate that uplifting of supports become more prominent in high skew-curve cases at acute corners, while obtuse corner reactions reach as high as 104% of total force transmitting to abutment. Reaction ratio monitored can also be used for deriving skew correction factors for skew-curved bridges. © 2019, Springer Nature Singapore Pte Ltd.","3D FEM modelling; Concrete box-girder bridges; Horizontally curved; Skew abutments; Skew correction factor; Support reaction","3D modeling; Abutments (bridge); Concrete beams and girders; Steel bridges; 3-D FEM; Concrete box girder bridge; Horizontally curved; Skew corrections; Support reaction; Box girder bridges",,,,,,,,,,,,,,,,"Nutt, R., Valentine, D.E., (2008) Development of Design Specifications and Commentary for Horizontally Curved Concrete Box-Girder Bridges.

Generally, the ultimate flexural behavior of concrete members with unbonded tendons is evaluated by the stress in unbonded tendons at ultimate state. Researchers have developed the equations using various analytical concepts, namely, moment–curvature relationship, empirical methods, strain reduction coefficient method, equivalent plastic hinge length method, and finite element method. The paper intends to present the performance of the prediction equations and suitable analytical concept for calculating the stress in tendons. Performance of prediction equations for calculating the stress at ultimate in unbonded tendons fps has been evaluated using experimental data published in the literature. In the next stage, an experimental investigation on the flexural behavior of post-tensioned concrete beam is done by authors, and the results have been used for evaluation. Also, the FEM analysis using ANSYS package is also performed and compared with test results.

In the present study, a 20 m span simply supported box-girder bridge with different degrees of skewness varying from 10 to 60° has been considered to investigate the effect of skew angle on transverse distribution of longitudinal stresses and coefficient of shear lag (CSL). The shear lag response of the skew box-girder bridges due to dead load has been compared with the right box-girder bridge, and it has been observed that up to 20° skewness, the CSL is not much affected by the skew angle; however, for the skew angles more than 20°, shear lag effect in the box girders decreases with increase in skew angle, and it becomes remarkably low compared to right box-girder bridges. Moreover, the study shows that for the highly skew bridges, the nature of longitudinal stresses alters. © 2019, Springer Nature Singapore Pte Ltd.","Finite element; Longitudinal stress; Shear lag; Skew box-girder bridge","Beams and girders; Bridge decks; Fiber optic sensors; Finite element method; Higher order statistics; Shear flow; Steel bridges; Linear elastic finite element analysis; Longitudinal stress; Shear lag; Shear lag effects; Simply supported box girders; Skew box girder; Skew bridges; Transverse distribution; Box girder bridges",,,,,,,,,,,,,,,,"Reissner, E., Analysis of shear lag in box beams by the principle of minimum potential energy (1946) Quarterly of Applied Mathematics, (3), pp. 268-278. , IV; Luo, Q.Z., Tang, J., Li, Q.S., Experimental studies on shear lag of box girders (2002) Engineering Structures, 24, pp. 469-477; Luo, Q.Z., Li, Q.S., Shear lag of thin-walled curved box girder bridges (2000) Journal of Engineering Mechanics, ASCE, 126 (10), pp. 1111-1114; Luo, Q.Z., Li, Q.S., Tang, J., Shear lag in box girder bridges (2002) Journal of Bridge Engineering, ASCE, 7 (5), pp. 308-313; Yang, L.F., Leung, A.Y.T., Li, Q.S., The stochastic finite segment in the analysis of the shear-lag effect on box-girders (2001) Engineering Structures, 23, pp. 1461-1468; Lertsima, C., Chaisomphob, T., Yamaguchi, E., Stress concentration due to shear lag in simply supported box girders (2004) Engineering Structures, 26, pp. 1093-1101; Luo, Q.Z., Tang, J., Li, Q.S., Liu, G.D., Wu, J.R., Membrane forces acting on thin-walled box girders considering shear lag effect (2004) Thin-Walled Structures, 42, pp. 741-757. , Science Direct; Chang, S.T., Yun, D., (1988) Shear Lag Effect in Box Girder with Varying Depth, 114 (10), pp. 2280-2292. , Journal of Structural Engineering, ASCE; Chang, S.T., Shear lag effect in simply supported prestressed concrete box girder (2004) Journal of Bridge Engineering, 9 (2), pp. 178-184. , ASCE; Bakht, B., Analysis of some skew bridges as right bridge (1988) The Journal Structural Engineering, ASCE, 114 (10), pp. 2307-2322; Mohseni, I., Rashid, A.R.K., Development of simplified skew correction factor equations for distribution of live load in highway multi-cell box-girder bridge (2012) International Conference on Transport, Environment and Civil Engineering (ICTECE), , August 25–26, 2012, Kuala Lumpur (Malaysia); Yang, H., Li, R., Chen, Z., Curve analysis of shear lag effect of box girder bridge (2015) International Conference on Materials, Environmental and Biological Engineering (MEBE), pp. 795-798; Song, Q., Scordelis, A., Shear-lag analysis of T-, I-, and box beams (1990) Journal of Structural Engineering, 116 (5), pp. 1290-1305; Szilard, R., (2004) Theory and Analysis of Plates, Classical and Numerical Method, , New Delhi: Wiley","Kumar, M.; Civil Engineering Department, India; email: manojkr@pilani.bits-pilani.ac.in",,,"Springer",,,,,23662557,,,,"English","Lect.

Based on this damage constitutive model and by using damage mechanics – additional load – finite element method, a three dimensional finite element analysis computer program is established. The damaging process and failure of a reinforced concrete arch structure which was removed from a real old bridge is simulated numerically. The damage parameters of concrete are determined through a targeting calculation process. The values of element damage and the nodal displacements along three directions under different load level are obtained. The theoretical results of the failure mode, displacements are in good agreement with the experimental observations. Numerical results reveal the complicated behavior of concrete in a damaging process. The reinforced concrete structures exhibit pronounced nonlinearity at large loading levels. © Springer Nature Switzerland AG 2019.","Arch structure; Damage mechanics; Nonlinearity; Numerical simulation; Reinforced concrete; Three dimensional finite element method","Arch bridges; Arches; Computer simulation; Concrete construction; Constitutive models; Finite element method; Numerical methods; Reinforced concrete; Arch structures; Calculation process; Damage constitutive model; Damage mechanics; Independent parameters; Nonlinearity; Three dimensional finite element analysis; Three-dimensional finite element method; Failure (mechanical)",,,,,,"Acknowledgement.

Methods—A 21-year-old male volunteer was included in this study. CT images were used to construct the finite element model of the spine from T1 vertebrae to sacrum. The material properties of biological tissues in the model were based on data of cadaver test and material test in the literatures. The range of motion of the model was compared with the previous study. The model was optimized until that the simulation results were similar with the literature results. Results—The 3D FE model of spine was developed that contained vertebrae from T1 to sacrum. The model consisted of 509,580 nodes and 445,722 hexahedrons. Conclusions—A 3D FE model of postoperative spine was successfully developed, which would serve as effective tool for subsequent biomechanical analysis. © 2019, Springer Nature Singapore Pte Ltd.","Biomechanics; Finite element analysis; Spine","Biological materials; Biomechanics; Composite bridges; Computerized tomography; Man machine systems; Systems engineering; Biological tissues; Biomechanical analysis; Biomechanical studies; Effective tool; Material tests; Range of motions; Spine; Three dimensional finite element model; Finite element method",,,,,,,,,,,,,,,,"Freburger, J.K., Holmes, G.M., Agans, R.P., Jackman, A.M., Darter, J.D., The rising prevalence of chronic low back pain (2009) Arch Intern Med, 169, pp. 251-258; Petersen, T., Laslett, M., Juhl, C., Clinical classification in low back pain: Best-evidence diagnostic rules based on systematic reviews (2017) BMC Musculoskelet Disord, 18, p. 188; Panjabi, M.M., Simpson, A.K., Ivancic, P.C., Pearson, A.M., Tominaga, Y., Yue, J.J., Cervical facet joint kinematics during bilateral facet dislocation (2007) Eur Spine J, 16, pp. 1680-1688; Gzik, M., Wolanski, W., Tejszerska, D., Experimental determination of cervical spine mechanical properties (2008) Acta Bioeng Biomech, 10, pp. 49-54; Yoganandan, N., Kumaresan, S., Pintar, F.A., Biomechanics of the cervical spine Part 2.
