Comparative study of Pushover analysis and normal method in seismic evaluation

The paper evaluates seismic performance of a two-layer frame structure under the effect of frequent earthquake and rare earthquake based on Pushover analysis,and makes comparison of Pushover analysis and the seismic analysis results of equivalent base shear method,response-spectrum method,time-history method.The result shows that Pushover analysis can accurately evaluate seismic performance of frame structure,especially can find the weak line of structure when evaluating the rare earthquake and provide a basis for seismic design of structure and strengthening.
