| 英文摘要 |
The detailed seismic evaluation is used to evaluate the seismic capability of structures. Presently, the most popular analysis method is the nonlinear pushover analysis. The nonlinear pushover analysis introduced by ATC-40 is based on the planar frames. If the pushover analysis is applied on the space frames, the method must be modified. In this study, the single modal pushover analysis and simple pushover analysis of space frames were discussed. The restrictions of single modal pushover analysis were also specified. For the pushover analysis of space frames the simple pushover analysis based on the planar frames is proposed to establish the capacity curve and capacity spectrum and can reasonably evaluate the seismic capability of buildings. |
