[摘要] 根据屈曲约束支撑与钢框架的合理刚度比设计多层屈曲约束支撑钢框架。为了比较不同屈曲约束支撑布置方式对抗震性能的影响，设计4中不同布置方式的结构模型。利用有限元软件SAP2000进行建模分析，分别采用底部剪力法、振型分解反应谱法、线性动力时程分析、非线性动力时程分析、静力弹塑性分析比较不同布置方式对结构抗震性能影响。探讨屈曲约束支撑不同布置方式的优劣，为屈曲约束支撑框架设计提供依据。

Abstract: The multi-storey steel frame with buckling restrained braces was designed according to the rational stiffness ratio of buckling restrained braces and steel frame. To compare the different layout of buckling restrained braces for seismic behaviors, four different layout forms of the structural model were designed. The models were established by finite element software SAP2000. The bottom of the shear method, response spectrum method, linear time history analysis, nonlinear time lustory analysis and pushover analysis were conducted to compare the different layout of buckling restrained
braces for seismic behaviors. The advantages and disadvantages of buckling restrained brace the different layouts are discussed, which are the reference for the design of buckling-restrained braces frame.
Keywords: rigidity ratio; layout form; time-history analysis; pushover analysis
