摘　　要：西安领事馆区大剧院建筑设计采用飘带状造型,钢屋盖采用单层与双层网壳相结合的结构形式。采用MIDAS Gen软件建立整体计算模型进行分析,采用3D3S软件对屋盖钢结构进行弹性分析,同时考虑几何与材料非线性并采用ANSYS软件进行结构稳定分析。结果表明:屋盖结构的应力变形及整体稳定满足规范要求。对复杂钢结构典型节点进行有限元分析,并根据结果对节点进行施工图设计。各项分析表明结构满足正常使用与地震作用下的性能要求。The architectural design of the Grand Theater in Xi’an Consulate District adopts a ribbon-like shape, and the steel roof adopts a structure that combines single-layer and double-layer lattice shells. MIDAS Gen software was used to establish an overall calculation model for analysis, and 3 D3 S software was used for elastic analysis of roof steel structure, while geometric and material nonlinearities were considered, and ANSYS software was used for structural stability analysis. The results show that the stress, deformation and overall stability of the roof structure meet the requirements of the specification. Finite element analysis on typical joints of complex steel structure was carried out, and the construction drawings of joints were designed according to the results. All the analyses show that the structure meets the performance requirements under normal use and earthquake action.
