The recently developed pushover analysis procedure has led a new dimension to performance-based design in structural engineering practices. Modeling for such analysis requires the determination of the nonlinear properties of each component in the structure, quantified by strength and deformation capacities, which depend on the modeling assumptions. With the increase in the magnitude of monotonic loading, weak links and failure modes in the multi-storey frames are usually formed. The force distribution and storey displacements are evaluated using static pushover analysis based on the assumption that the response is controlled by fundamental mode and no mode shift takes place. In view of the intensive construction, we required a completely up-to-date, versatile method of a seismic analysis and design of structures are essential. The major focus of study is to bring out the superiority of pushover analysis method over the conventional analysis method recommended by the code. The results obtained from the various studies show that the response spectrum method underestimates the response of the model in comparison with pushover analysis. It is also seen that model participation of higher modes contributes to better results of the response distribution along the height of the building. Also pushover curves are plotted to illustrate the displacement as a function of base shear.
