[提要]  天津大學(xué)體育場(chǎng)看臺(tái)罩棚采用了大跨懸挑鋼桁架結(jié)構(gòu)，針對(duì)其跨度較大、形狀不規(guī)則的特點(diǎn)，詳細(xì)闡述了該種結(jié)構(gòu)的體系布置情況和靜、動(dòng)力分析過(guò)程。體系布置采用三角形桁架結(jié)構(gòu)，通過(guò)檁條和支撐將其連結(jié)成一個(gè)穩(wěn)定的整體。最后簡(jiǎn)要地介紹了制作和安裝方法。
[關(guān)鍵詞]  大跨懸挑鋼桁架結(jié)構(gòu)  結(jié)構(gòu)設(shè)計(jì)  靜力計(jì)算  動(dòng)力反應(yīng)  反應(yīng)譜法  時(shí)程分析法

The cantilever of Tianjin university stadium is designed with long-span steel truss structure. The structure has a wide span and irregular appearance. The situation of structural system and the process of the static and dynamic analysis are described in detail. In the static analysis, the effect of wind load and seismic load is emphasized. In the dynamic analysis,the response spectrum method and the time history analysis method are used to check the safety of the structure. The installation method is introduced briefly.
Keywords:  long-span cantilever steel truss structure; structural design; static analysis; dynamic response
