| 摘 要： | 对既有火电厂房弹塑性分析的方法与不足进行了讨论。基于某钢支撑框排架火电厂房结构，应用Perform3D进行弹塑性时程分析。通过分析结构在中震和大震作用下的弹塑性动力响应，进一步了解了复杂火电厂房的抗震性能，并且验证了支撑框排架火电厂房建模考虑支撑屈曲的重要性，得出了若干有益结论。

| Abstract: | Existing nonlinear analyses methods of power plant structures were reviewed and some problems were identified. By using the finite element software Perform 3D, detailed nonlinear time-history analyses were performed on a steel braced frame power plant structure. Elasto-plastic dynamic responses of the structure under seismic loadings with two different seismic intensities, i.e., design earthquakes and major earthquakes were obtained. Seismic performance of this structure was further investigated and the influence of brace buckling in modeling this braced steel frame power plant structure was discussed based on analysis results. |
