Pushover analysis is a static, nonlinear procedure using simplified nonlinear technique to estimate seismic
structural deformations. It is an incremental static analysis used to determine the force-displacement relationship, or the
capacity curve, for a structure or structural element. In technique a computer model of the building is subjected to a
lateral load of a certain shape (i.e., inverted triangular or uniform). This study aims at evaluating and comparing the
results of different methodologies namely the ones described by the ATC-40 and the FEMA-273 using nonlinear static
procedures, with described acceptance criteria. The methodologies are applied to an existing building designed as per
the IS 456-2000 and IS 1893-2002 (Part II) in the context of Performance Based Seismic Design procedures. It gives
clear idea about the performance of building by applying different load combination .
