Abstract The analysis of seismic assessment of buildings will result in the plastic hinge property of members. But the plastic hinge properties of members were studied base on the theory in the past, less studies have compared to existing building test data. Since 1995, the center for Research on Earthquake Engineering carry out a series of static push-over tests for existing building, in order to get result of the correspond to earthquake damage of reality. This study calculates the strength and plastic deformation of members beam,such as column and brick wall. By using the analysis procedure of nonlinear static push-over in SAP2000, the results of simulation compared to the results of push-over test for existing buildings.
