［摘要］天津海河教育園區(qū)體育中心體育場(chǎng)為29萬(wàn)座的中型體育場(chǎng)。體育場(chǎng)周圈覆蓋屋蓋罩篷。屋蓋采用鋼管桁架結(jié)構(gòu)，每榀主桁架均為內(nèi)挑桁架，單榀最大挑跨40m，根據(jù)下部柱網(wǎng)布置，主桁架采用不同支座形式。對(duì)本工程屋蓋的結(jié)構(gòu)布置進(jìn)行了全面介紹，采用SAP2000軟件對(duì)屋蓋結(jié)構(gòu)進(jìn)行了整體分析，并對(duì)單榀桁架進(jìn)行了補(bǔ)充計(jì)算分析，采用ANSYS軟件對(duì)支座節(jié)點(diǎn)及典型節(jié)點(diǎn)進(jìn)行了有限元分析，計(jì)算結(jié)果均滿足相關(guān)規(guī)范的要求。

［關(guān)鍵詞］鋼管桁架結(jié)構(gòu)； 風(fēng)洞試驗(yàn)； 相貫節(jié)點(diǎn)

Abstract:Tianjin Haihe Education Park Sports Center Stadium is a 29,000seat mediumsized stadium with roof canopy around the stadium body. The steel pipe truss structure was adopted in the roof. Every piece of the main truss is an innercantilever truss with the biggest cantilever span of 40m. The main truss adopts different support forms according to the lower column grid arrangement. The structural layout of the roof was introduced comprehensively. An overall analysis was carried out on the roof structure by using SAP2000 software. The calculation and analysis of the singlepiece trusses were supplemented. The finite element analyses were carried out on support joints and typical joints  by using ANSYS software, and the calculation results can meet the requirements of the relevant codes.

Keywords:steel pipe truss structure; wind tunnel test; tubular joint
