Seismic Performance Evaluation of RC Building through Static Non Linear Pushover Analysis and Comparison by Changing the Size of Rectangular Column

While studying the performance based seismic design the prediction of inelastic seismic responses and the evaluation of seismic performance of a building structure are very important subjects. The seismic performances of reinforced concrete buildings are evaluated by nonlinear static pushover analysis in this research. A finite element model that can accurately simulate nonlinear behaviour of building is formulated by considering several important effects. Both global response such as system ductility demand and local response such as inter-story drift are investigated in this research. A numerical example is performed on a 9-story reinforced concrete building has been simulated. The performances have also been compared by changing the different sizes of the rectangular columns. Finally, the global and local responses obtained from the modal pushover analysis are compared with those obtained from the nonlinear dynamic analysis of MDOF system.
