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。
Bohai International Convention Center swimming pool and basketball arena located in Caofeidian Economic Development Zone, with a total construction area of 16000 m2, two gymnasiums are used two-way bias cross-truss arch membrane shell structure. The three-dimensional modeling method for the complex roof structure is introduced. The wind tunnel test is conducted on the wind-sensitive membrane structure and the wind pressure distribution coefficient is obtained. The wind-induced vibration response of the roof is determined and the wind-induced vibration coefficient is determined. The overall stability of the arched shell and the whole roof force analysis; the above analysis results to ensure the safety of structural design and meet the requirements of the norms.
