Abstract: 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 3D3S 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. 

Keywords:Grand Theater in Xi’an Consulate District； lattice shell structure; steel roof； temperature effect； stability analysis； joint analysis
