【提要】 佛山体育中心新体育馆屋面是轮辐式的全张拉索膜结构。采用非线性有限元法对结构的找形过程进行了分析，计算了不同角度风荷载作用下结构的风压分布，得到了结构的最大和最小风压及结构整体的变形，对结构的静力稳定问题进行了探讨。分析结果表明，整体张拉结构的预应力施加与施工过程的控制关系密不可分，应注意施工过程中的分阶段分析。

Design and Analysis of Cablemembrane Roof Structure in New Stadium of Foshan Sports Center/Sun Wenbo,Yang Shuyong(Architecture Design and Research Institute,SCUT, Guangzhou 510640,China)
Abstract:The wheelspoke shaped integral pretension cablemembrane structure is adopted in the new stadium of Foshan sports center.The nonlinear FEM is used to simulate the formfinding process,and the wind pressure distribution of structure under different wind angle actions is calculated.The most disadvantage pressure and the structural deformation are got.The static stability of the structure is discussed.The results show that the pretension adding and construction control of the integral pretension structure are colosed tightly,and the substage analysis should be conducted in construction.
