P-Delta Effects on Tall Concrete Buildings
Description
P-delta effect is the secondary moment which is produced by wind or seismic effects. For tall reinforced concrete building the P-delta effects have a significant role on building stability, because in many cases it has been seen that the collapse of tall buildings is a function of slenderness and secondary order effects. One of the very important parts which has effects on these types of buildings is P-delta, which has significant effect on building stability and ductility during the design based on seismic or wind. In this research paper it will be seen that P-delta effect is an important phenomenon for structure stability, axial force, shear capacity, story drift, maximum displacement and moment. If the P-Delta effect does not include in analysis and design phase, if resulted, the structure based on its self-weight and secondary moment may damage in many parts of the building or even collapse of structure that it will occur during seismic or wind load. Due to complexity and low knowledge of P-Delta analysis, designers, engineers and architectures are prone to perform linear static analysis which may eventually become a cause of catastrophic collapse of the tall structure.
