摘　　要：以西宁热电厂某新建工程为背景,采用通用有限元软件MIDAS-GEN对主厂房竖向框排架结构分别在抗震设防烈度7度(0.15g)、8度(0.20g)下进行静力弹塑性(Push-over)分析及抗震性能评估.结果表明:在抗震设防烈度为7度(0.15g)地震作用下,主厂房竖向框排架结构能够满足抗震性能要求且经济性较好,而高烈度区8度(0.20g)及以上或重要的电厂不宜采用竖向框排架结构形式.Based on a new construction project of Xining Thermal Power Plant,the general finite element software MIDAS-GEN is used to analyze the static elastoplastic(Push-over)analysis and seismic evaluation of the vertical frame-bent structure of the main power house under seismic fortification intensity of 7 degrees(0.15g)and 8 degrees(0.20g).The results show that the vertical frame-bent structure under seismic fortification intensity of 7 degrees(0.15g)can meet earthquake-resistant requirements and have good economic efficiency.However,under seismic fortification intensity of 8 degrees(0.20g)and above or for important power plants,the vertical frame-bent structure should not be used.

关 键 词：框排架结构 静力弹塑性(Push-over) 主厂房 抗震性能
