[摘要] 根據(jù)屈曲約束支撐與鋼框架的合理剛度比設(shè)計(jì)多層屈曲約束支撐鋼框架。為了比較不同屈曲約束支撐布置方式對抗震性能的影響，設(shè)計(jì)4中不同布置方式的結(jié)構(gòu)模型。利用有限元軟件SAP2000進(jìn)行建模分析，分別采用底部剪力法、振型分解反應(yīng)譜法、線性動(dòng)力時(shí)程分析、非線性動(dòng)力時(shí)程分析、靜力彈塑性分析比較不同布置方式對結(jié)構(gòu)抗震性能影響。探討屈曲約束支撐不同布置方式的優(yōu)劣，為屈曲約束支撐框架設(shè)計(jì)提供依據(jù)。

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
