This paper aims at the main structural forms of multi-storey buildings (frame structure, masonry structure and bottom frame structure) in our country in the whole life cycle, and compares the analysis results of bottom shear method, mode decomposition response spectrum method, time history analysis method and Pushover method by using the general finite element software SAP2000. Then it is converted into the displacement response of the corresponding multi-degree-of-freedom structure, and the total displacement response of the structure is obtained through the mode combination method. By comparing it with the target displacement of the shear wall, it is judged whether the design result meets the performance target requirements. The results show that the four seismic performance evaluation methods have little difference in the analysis results of multi-storey buildings. Among them, Pushover method is a fast, simple and practical evaluation method. Weak links can be found when evaluating the seismic performance of structures under rare earthquakes, which can provide more references for seismic performance evaluation and reinforcement.
