摘　　要：为了研究普通钢框架结构、单向斜杆支撑钢框架结构、交叉支撑钢框架结构、人字形支撑钢框架结构在地震作用下的抗震性能,利用有限元软件ANSYS对四种不同支撑类型的钢框架结构分析在天津波、Taft波、墨西哥波地震作用下的振型、频率、层间位移、层间位移角。通过对比有限元模拟分析结果得出人字形支撑是所有支撑类型中抗震性能最优的支撑类型。In order to study the common steel frame structure,unidirectional diagonal support steel frame structure,cross support steel frame structures,herringbone support the seismic performance of steel frame structure under seismic action,using the finite element software ANSYS to support for four different types of steel frame structure analysis in Tianjin wave,Taft wave,Mexico wave,to analysis frequency,displacement,the interlayer displacement angle between the layers.By comparing the results of finite element simulation,it is concluded that the herring-bone bracing is the best seismic performance among all bracing types.
