摘　　要：为了研究屈曲约束支撑在高层钢框架结构中的减震效果,利用有限元分析软件SAP2000分别对纯框架、普通支撑框架和屈曲约束支撑框架3种模型进行了罕遇地震作用下的非线性时程分析。通过对时程分析结果进行对比,得出了在高层钢框架结构中设置屈曲约束支撑可以大幅度提高结构的抗震性能。To study the effect of buckling-restrained braces in high-rise steel frame structure,three models were established by the finite element analysis software SAP2000,namely steel frame,common braced frame and buckling-restrained braced frame.The three models were analyzed under action of rare earthquake by the method of nonlinear time history analysis.According to the time history analysis result,it indicated that seismic behavior of the structure is significantly improved by buckling-restrained braces in high-rise steel frame.
