摘　　要：为了研究大型火电厂主厂房钢结构框排架结构的抗震性能,对相似比为1/10的模型结构进行了拟动力试验.利用SAP2000软件对钢框排架进行了弹塑性时程分析,并与试验结果进行比较分析,两者吻合较好.研究结果表明:火电厂主厂房钢框排架结构在8度、9度罕遇地震作用下能满足变形要求,但结构存在较多的薄弱环节,在设计中应引起高度重视.In order to study the seismic performances of the steel frame-bent structure of a large-scale thermal power plant, the pseudo-dynamic experiments about the model structure with 1/10 scale was conducted. In this paper, the steel frame-bent structure is calculated by elasto-plastic time-history analysis method using SAP2000 program, and the numerical analysis results agree well with the experimental results. It is shown that the main plant of steel frame structure can meet the deformation requirements at Mag.8 or Mag.9 rare earthquake. However, there are quite a few weak points in the structure that require high attention in the design process.
