【提要】 佛山體育中心新體育館屋面是輪輻式的全張拉索膜結(jié)構(gòu)。采用非線性有限元法對(duì)結(jié)構(gòu)的找形過(guò)程進(jìn)行了分析，計(jì)算了不同角度風(fēng)荷載作用下結(jié)構(gòu)的風(fēng)壓分布，得到了結(jié)構(gòu)的最大和最小風(fēng)壓及結(jié)構(gòu)整體的變形，對(duì)結(jié)構(gòu)的靜力穩(wěn)定問(wèn)題進(jìn)行了探討。分析結(jié)果表明，整體張拉結(jié)構(gòu)的預(yù)應(yīng)力施加與施工過(guò)程的控制關(guān)系密不可分，應(yīng)注意施工過(guò)程中的分階段分析。

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.
Keywords:wheelspoke; cablemembrane structure; tensegrity;calculation; analysis
