(北京市建筑設計研究院,北京 100045)[摘要]渤海國際會議中心游泳館和籃球館位于曹妃甸經濟開發(fā)區(qū),總建筑面積1.6萬m2,兩個體育館的屋蓋均采用雙向斜交桁架拱殼支承膜結構。介紹了復雜屋蓋結構三維建模方法;對風敏感的膜結構進行了模型風洞試驗并得到風壓分布系數(shù);進行了屋蓋風振響應分析并確定風振系數(shù);完成了雙向斜交桁架拱殼整體穩(wěn)定驗算及屋蓋整體受力分析;上述各項分析結果保證了結構設計的安全性并滿足規(guī)范各項要求。[關鍵詞]游泳館;籃球館;拱殼;膜結構;風洞試驗;風振分析;整體穩(wěn)定Design of membrane structure roofs of natatorium and gymnasium in Bohai International Convention CenterWei Dong, Wang Zhigang, Gao Xiaojing, Zhou Wenyuan(Beijing Institute of Architectural Design, Beijing 100045, China)Abstract:The two stadiums of Bohai International Convention Center, one natalorium and one gymnasium, are located in Caofeidian Economic Development Zone. The two gymnasiums are 16 000m2 and their roofs are designed as membrane structures. A 3D modeling method for complex space structure is introduced. As membrane structures are wind-sensitive, the wind tunnel test is done and the wind-induced dynamic coefficients are calculated. The random wind response analysis are done and wind-induced vibration coefficient are calculated. The integrate buckling analysis of the shell and the analysis of the membrane and steel roof structure are done. The analysis results prove that the whole structural design are safe and up to the code.Keywords:gymnsium; arch shell; membrane structure; wind tunnel test; wind-induced vibration; integrate buckling; analysis作者簡介:衛(wèi)東,男,博士,教授級高工,Email:weidong999999@yahoo.com.cn。參考文獻[1]CECS158:2004 膜結構技術規(guī)程[S]. 北京: 中國計劃出版社, 2004.[2]JGJ61—2003 網殼結構技術規(guī)程[S]. 北京: 中國建筑工業(yè)出版社, 2003.[3]GB50017—2003 鋼結構設計規(guī)范[S]. 北京: 中國建筑工業(yè)出版社, 2003.
