［摘要］某会展中心采用钢管混凝土框架-屈曲约束支撑结构体系，主体结构跨度大、层高大且平面不规则。屈曲约束支撑作为耗能构件，分别应用在结构框架及大跨延性桁架两个部分。采用SAP2000软件进行动力弹塑性时程分析，考察罕遇地震作用下结构的性能。计算结果表明：屈曲约束支撑可以显著提高结构的侧向刚度、延性及耗能能力；结构在罕遇地震作用下具有良好的抗震性能，能够满足规范的要求。

Abstract: An exhibition and convention center used concrete stilled steel tubular frame with buckling restrained braces(BRBs) structure, with long span, high height and plane irregularity. BRBs were used as energy dissipation members in structure frame and long span ductile truss. The elastic-plastic time history analysis was carried out by SAP2000 software to study the seismic behavior of the structure under rare earthquakes. The results show that BRBs can significantly improve the lateral rigidity, ductility and energy dissipation capacity of the structure. The structure has good seismic performance under rare earthquake, and can satisfy the code requirements.  

Keywords:energy dissipation design； BRB； elastic-plastic analysis； ductile truss
