［摘要］成都某項目為雙塔低位連體結(jié)構(gòu)。連接體跨度、高度、寬度較大，受力較為復(fù)雜。為了滿足建筑功能要求，連接體部分選用鋼桁架結(jié)構(gòu)體系。根據(jù)工程特性，對結(jié)構(gòu)設(shè)定了適宜的性能目標(biāo)，針對連接體鋼桁架進行了設(shè)防烈度地震下中震彈性和大震不屈服的計算分析；針對桁架結(jié)構(gòu)關(guān)鍵節(jié)點進行了補充分析；對連體舒適度進行了專項分析。分析結(jié)果表明，結(jié)構(gòu)受力和抗震性能滿足要求，安全可靠、使用舒適并具有較好的經(jīng)濟性。

Abstract:A project in Chengdu consists of two towers connected as low altitude. The span, height and width of the connected structure are relatively large and mechanical conditions are relative complex. In order to meet the functional requirements of the building, the steel truss structural system is used in the connected part. According to the engineering characteristics, the optimum performance targets were set up, and the elastic analysis under the medium earthquake and non-yielding analysis under the rare earthquake were carried out on the connected steel truss structure under the condition of fortification earthquake. A supplementary analysis of the key nodes of the truss structure was carried out. A special analysis of the comfort degree of the connected structure was performed. The analysis results show that the structural mechanism and seismic performance meet the requirements with safety, reliability, comfort and good economic performance.
Keywords:connected structure; steel truss; performance-based design; node analysis
