扬州跳水游泳馆屋盖为大跨度承重屋面杂交空间结构,主要包含正交平面桁架、单层网壳、正交双向索桁架三种结构体系。重点介绍了该工程中模态分析、钢屋盖整体非线性内力分析、施工模拟等设计方法,得到一些有价值的结论,供类似的工程设计参考。
Yangzhou Diving Swimming Center roof is a long-span load-bearing roof hybrid space structure, which includes orthogonal plane truss, single-layer reticulated shell, orthogonal bidirectional cable trusses three structural systems. The design methods of modal analysis, overall nonlinear internal force analysis of steel roof, construction simulation and so on are introduced emphatically, and some valuable conclusions are obtained for reference of similar engineering design.
