［摘要］2010年上海世博会中国航空馆面积4 880m2，是集异形钢框架、不规则单层网壳、膜下二次结构为一体的复杂钢结构体系。设计针对整体结构模型、主体结构模型、独立膜下二次结构模型、独立等候大厅单层网壳模型进行静力、稳定性能等方面的对比分析。分析结果表明，工程膜下二次结构与主体结构相互影响很大，应进行整体结构共同工作分析，并依据分析结果进行优化设计。

Abstract:China Aviation Pavilion in World Expo 2010 Shanghai, the area of which is 4 880m2, has an extraordinary shape of the steel frame, the irregular single-layer shell, the secondary structure under the membrane of the complex steel structure system as a whole. The comparative analysis of static, stability performance are conducted for the overall structural model, the main structural model, the secondary structural model under the membrane, and single-layer shell model of the independent lobby. The results show that the secondary structure has an apparent impact on the main structural model. Therefore, the joint work analysis of the overall structure should be carried out, and the optimal design is performed according to the analysis results.
Keywords:main structure; secondary structure under membrane; modal analysis; stability analysis; joint work
