摘　　要：渤海国际会议中心游泳馆和篮球馆位于曹妃甸经济开发区,总建筑面积1.6万m2,两个体育馆的屋盖均采用双向斜交桁架拱壳支承膜结构。介绍了复杂屋盖结构三维建模方法;对风敏感的膜结构进行了模型风洞试验并得到风压分布系数;进行了屋盖风振响应分析并确定风振系数;完成了双向斜交桁架拱壳整体稳定验算及屋盖整体受力分析;上述各项分析结果保证了结构设计的安全性并满足规范各项要求。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 000m^2 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.
