| Abstract: | Based on the nonlinear static(Pushover) analysis method and random vibration theory,the frame structure is analyzed in this paper.The capacity spectrum method of performance evaluation can compute the displacement and damnification in each floor under the rare earthquake.The Park-Ang model is applied to estimate the damage index of structures under seismic action and combined with the nonlinear static analysis method,the seismic performances of structures are evaluated synthetically.The method developed can... |
