(五洲工程設(shè)計研究院，北京 100053)［摘要］北京理工大學體育文化綜合館鋼結(jié)構(gòu)屋蓋由鋼管相貫圓弧拱桁架及曲線屋面桁架組成。根據(jù)對圓弧拱桁架及曲線屋面桁架共同工作的分析，結(jié)構(gòu)上采取一些措施減小相互間不利影響，如吊點處采用鉸接節(jié)點、邊支座采用滑動支座等。為增加屋架的出平面剛度，設(shè)置了與屋架垂直的空間桁架，最終設(shè)計時將其間隔設(shè)置，屋架為兩兩相連，既滿足屋架出平面剛度需要，又不對下部結(jié)構(gòu)產(chǎn)生過大反力。［關(guān)鍵詞］拱形桁架；鋼管桁架；穩(wěn)定分析；風洞試驗；萬向轉(zhuǎn)動支座；滑動支座Steel roof structure design of Beijing Institute of Technologe Athletics Culture CenterZhang Ying, Shao Qingliang, Ding Dayi, Zheng Yan(Wuzhou Engineering Design and Research Institute, Beijing 100053, China)Abstract:Beijing Institute of Technologe Athletics Culture Center is a middle scale stadium building. The steel structure roof system consists of steel hollow truss arc arch and curve roof truss. It mainly describes the structure design of steel structure roof system and key techniques. According to analysis of co-working of steel hollow truss arc arch and curve roof truss, we adopted some measures to minish the disadvantageous influence. For example, adopting hinged support, guided support, setting distant support truss to enhance lateral ridity of curve roof truss etc.Keywords:truss arc arch; steel hollow truss; stability analysis; wind tunnel test; all directions support; glide support作者簡介：張英，碩士，研究員高工，一級注冊結(jié)構(gòu)師，Email:1974@wuzhou.com.cn。參考文獻［1］邵慶良，張英.北京理工大學體育文化綜合館風洞試驗研究［J］.建筑結(jié)構(gòu)，2007，37(3).［2］GB50017—2003鋼結(jié)構(gòu)設(shè)計規(guī)范［S］.北京：中國計劃出版社，2003.［3］陳冀.鋼結(jié)構(gòu)穩(wěn)定理論與設(shè)計［M］.北京：科學出版社，2001.［4］MIDAS技術(shù)手冊：結(jié)構(gòu)分析與設(shè)計［M］.北京邁達斯技術(shù)有限公司，2002.［5］北京大學湍流與復雜系統(tǒng)國家重點實驗室、五洲工程設(shè)計研究院.北京理工大學體育文化綜合館風荷載風洞模擬實驗研究報告［R］.2003.［6］［荷］J.沃登尼爾著.鋼管截面的結(jié)構(gòu)應(yīng)用［M］.張其林，劉大康譯.上海：同濟大學出版社,2004.
