張敏，宋鴻譽(yù)，張杜（蘇州設(shè)計(jì)研究院股份有限公司， 蘇州 215021）［摘要］揚(yáng)州體育公園體育館屋蓋鋼結(jié)構(gòu)為大跨空間管桁架結(jié)構(gòu)。除對(duì)屋蓋鋼結(jié)構(gòu)進(jìn)行單體模型計(jì)算分析外，還對(duì)考慮下部混凝土結(jié)構(gòu)的整體模型進(jìn)行計(jì)算分析，結(jié)合實(shí)際卸載情況進(jìn)行施工卸載分析。由于比賽館節(jié)點(diǎn)桿件交匯多，受力復(fù)雜，特別對(duì)轉(zhuǎn)換桁架下弦節(jié)點(diǎn)進(jìn)行了有限元分析及三組足尺節(jié)點(diǎn)試驗(yàn)，采取相應(yīng)加強(qiáng)措施確保節(jié)點(diǎn)安全。［關(guān)鍵詞］揚(yáng)州體育公園； 四錐臺(tái)形空間管桁架結(jié)構(gòu)； 轉(zhuǎn)換桁架； 卸載分析； 節(jié)點(diǎn)試驗(yàn)中圖分類號(hào)：TU393.3 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2013)20-0006-05Structure design on steel roof of stadium in Yangzhou Sports ParkZhang Min, Song Hongyu, Zhang Du(Suzhou Institute of Architectural Design Co., Ltd., Suzhou 215021, China)Abstract: The steel roof of stadium in Yangzhou Sports Park is a large-span spatial tube truss structure. The model of steel roof structure was calculated independently while the whole model with lower concrete structure was analyzed considering construction unloading. The nodes of steel roof are formed by many members and have complicated loading conditions. Lower chord nodes of conversion truss were analyzed by finite element method and three groups of full-size nodes tests. Measures were taken to ensure the safety of nodes.Keywords: Yangzhou Sports Park; four cone-shaped spatial tube truss structure; conversion truss; unloading analysis; node test作者簡(jiǎn)介：張敏，教授級(jí)高級(jí)工程師，一級(jí)注冊(cè)結(jié)構(gòu)工程師，副總工程師，Email:min.zhang@siad-c.com。參考文獻(xiàn)［1］GB 50017—2003 鋼結(jié)構(gòu)設(shè)計(jì)規(guī)范［S］. 北京:中國(guó)計(jì)劃出版社，2003.［2］東南大學(xué)土木工程學(xué)院. 揚(yáng)州體育館鋼結(jié)構(gòu)節(jié)點(diǎn)試驗(yàn)報(bào)告［R］. 2005.
