摘　　要：随着门式刚架轻钢结构的广泛应用,其抗震性能得到关注,但是目前门式刚架结构抗震性能方面的研究还相对较少,相关规范规程对其抗震设计的规定也不够细致,制约着这种结构形式在高烈度抗震设防地区的应用。本文利用ANSYS软件对由两榀刚架组成的整体结构进行弹塑性时程分析,通过与一榀刚架和实验数据的对比,分析门式刚架结构在地震作用下的反应,并得出一些有用的结论,对以后的理论分析和工程实践提供参考。As the portal frame of light steel structure extensive application, the seismic performance pay for attention. However, at present, the research on seismic behavior of portal frame is lack, the relative standards on seismic design are also not well treated, which lead to the application of this structure is limited in high seismic areas. In this paper,dynamic elas-to-plastic time-history analysis of the portal frame of two frames, is simulated by ANSYS program a-large-scale integrated general-purpose finite element analysis softwarc, through with a hinged frame and experimental data contrast, analysing the portal frame structure under earthquake effect reaction. And, it gets some useful conclusions in regard to engineers and technicians. To provide the reference for the following the theoretical analysis and engineering practice.
