［摘要］2010年上海世博會(huì)中國(guó)航空館面積4 880m2，是集異形鋼框架、不規(guī)則單層網(wǎng)殼、膜下二次結(jié)構(gòu)為一體的復(fù)雜鋼結(jié)構(gòu)體系。設(shè)計(jì)針對(duì)整體結(jié)構(gòu)模型、主體結(jié)構(gòu)模型、獨(dú)立膜下二次結(jié)構(gòu)模型、獨(dú)立等候大廳單層網(wǎng)殼模型進(jìn)行靜力、穩(wěn)定性能等方面的對(duì)比分析。分析結(jié)果表明，工程膜下二次結(jié)構(gòu)與主體結(jié)構(gòu)相互影響很大，應(yīng)進(jìn)行整體結(jié)構(gòu)共同工作分析，并依據(jù)分析結(jié)果進(jìn)行優(yōu)化設(shè)計(jì)。

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
