Pushover analysis, a widely used method for seismic performance evaluation of a structure, is a static nonlinear procedure in which the magnitude of the structural loading is incrementally increased in accordance with a certain predefined patterned.
The static pushover analysis is becoming a popular tool for seismic performance evaluation of existing and new structures. The expectation is that the pushover analysis will provide adequate information on seismic demands imposed by the design ground motion on which the structural system and its component.
