the prediction of inelastic seismic responses and the evaluation of seismic performance of a building structure are very important subjects while studying the performance based seismic design. 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 dimensions of the buildings have been kept constant and only the column sizes have been changed. Three different combinations of the circular column dimensions are taken and the nonlinear response of each is evaluated by using the pushover analysis. The buildings are designed for the gravity and seismic loadings as per IS 456: 2000 and IS 1893: 2002.
