Comparative Study between Force Based Design Method and Performance Based Seismic Design of Reinforced Concrete Shear Walls

Abstract

This research studies the performance of reinforced concrete (RC) structures under the effect of seismic load. Mostly, design codes demonstrates the effect of seismic load on the structures as a lateral force and assign a force reduction factor (R) for structures in order to take into consideration the ductility provided by the system, without taking into consideration level of damage of structures. The performance seismic method gives better prediction of the structure behavior under seismic load. performance based design methods are the capacity spectrum and displacement coefficient method which is carried out by applying nonlinear pushover analysis leading to formation of plastic hinges that give an indication about the behavior level of the structure. In this research a verification study will be carried out to verify the results of the non-linear pushover analysis through comparing the pushover analysis results applied on shear walls with experimental wall results. Also the performance based design method and force based method will be applied on RC shear wall buildings with different heights and different reinforcement ratios of the structural elements using different seismic zones and the results will be compared with each other in terms of base shear, drift. This comparison is applied also between the performance based design methods to show the difference between these methods.
