| 摘 要： | 对一大跨度钢-索-膜空间混合结构建立了整体结构计算模型和简化的子结构计算模型，并分别进行了静、动力计算。计算结果表明：两种模型计算的结果相差很大，钢结构杆件应力相差64％，竖向位移相差58％，侧向位移相差150％，索的应力相差79％，表明了整体结构计算分析的必要性。

| Abstract: | With an actual gymnasium of a long-span spatial steel-cable-membrane hybrid structure as the calculation model, both static and dynamic analyses were performed by employing the global analysis for the whole hybrid structure, and the substructural analysis for the truss arch substructure, and the cable-membrane substructure etc., and the stresses and displacements of structural members were compared during global and substructural analyses. The numerical results show that serious errors exist in the substructural analysis for the hybrid structure, and the global analysis is necessary for the hybrid structure under the excitation of static loads and seismic loads. |
