［摘要］西安領(lǐng)事館區(qū)大劇院建筑設(shè)計采用飄帶狀造型，鋼屋蓋采用單層與雙層網(wǎng)殼相結(jié)合的結(jié)構(gòu)形式。采用MIDAS Gen軟件建立整體計算模型進行分析，采用3D3S軟件對屋蓋鋼結(jié)構(gòu)進行彈性分析，同時考慮幾何與材料非線性并采用ANSYS軟件進行結(jié)構(gòu)穩(wěn)定分析。結(jié)果表明：屋蓋結(jié)構(gòu)的應(yīng)力變形及整體穩(wěn)定滿足規(guī)范要求。對復(fù)雜鋼結(jié)構(gòu)典型節(jié)點進行有限元分析，并根據(jù)結(jié)果對節(jié)點進行施工圖設(shè)計。各項分析表明結(jié)構(gòu)滿足正常使用與地震作用下的性能要求。

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
