Dynamic and Comparative Analysis of Composite Structures for Seismic Resistance

Abstract 
The study primarily investigates three main structural typologies—Reinforced Concrete (RC) 
frames, Steel-framed structures, and Composite Concrete-Steel constructions—under severe 
seismic loading conditions. A key focus is the implementation and efficacy of lateral load
resisting systems, including shear walls and various bracing systems (such as curved bracing 
and Buckling Restrained Braces, or BRB) in controlling dynamic response parameters like base 
shear, story drift, and displacement. The structural behaviour is modelled and analysed using 
advanced numerical methods, such as the Response Spectrum Method, adhering to 
international and national building codes for earthquake-resistant design. Beyond structural 
mechanics, the work includes an essential cost and time analysis comparing the construction 
duration and overall project economics of composite construction versus precast and 
conventional methodologies. This holistic approach aims to identify the optimum structural 
and material solution that balances superior seismic performance and structural safety with 
construction speed and economic viability for high-rise projects in earthquake-prone regions.
