摘　　要：本文采用SAP2000建立了两种模型:模型1(钢框架结构,不加支撑)和模型2(钢框架-支撑结构,加X形支撑)。对两种模型分别进行模态分析、反应谱分析和时程分析,得出两模型的基本动力性能、层间位移和层间位移角等一些重要结果。比较分析数据,得出钢框架-支撑结构能够很好地增加结构的抗侧移刚度,减少高层平面不规则框架结构的位移。从而提高了高层平面不规则钢框架结构在多遇地震下的抗震性能。In this paper, two models were established by using SAP2000 ： Model 1 was steelframe structure （without support） and model 2 was steel frame-supporting structure （ with X-shaped support） . The results of modal analysis, responstime history analysis showed that the two models had some important results, such as basic dynamic performment and interlayer disp）lacement angle. It was concluded that the steel frame-braccd structure could increase the lateral stiffness of thestructure and reduce the displaccment of the irregular frame structure, which improved the seismic behavior of the high-rise plane irregu-lar steel frame structure under the condition of frequent earthquakes.
