［摘要］某會(huì)展中心采用鋼管混凝土框架-屈曲約束支撐結(jié)構(gòu)體系，主體結(jié)構(gòu)跨度大、層高大且平面不規(guī)則。屈曲約束支撐作為耗能構(gòu)件，分別應(yīng)用在結(jié)構(gòu)框架及大跨延性桁架兩個(gè)部分。采用SAP2000軟件進(jìn)行動(dòng)力彈塑性時(shí)程分析，考察罕遇地震作用下結(jié)構(gòu)的性能。計(jì)算結(jié)果表明：屈曲約束支撐可以顯著提高結(jié)構(gòu)的側(cè)向剛度、延性及耗能能力；結(jié)構(gòu)在罕遇地震作用下具有良好的抗震性能，能夠滿足規(guī)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
