2010年上海世博会中国航空馆面积4880m2,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。
China World Expo 2010 Shanghai World Expo area of 4880m2, is a special-shaped steel frame, irregular single-layer reticulated shell, membrane secondary structure as one of the complex steel structure system. The design is contrasted and analyzed in terms of the static structure and the stability of the single-layer reticulated shell model in the independent waiting hall according to the overall structural model, the main structural model, the sub-structure under the submerged membrane model. The analysis results show that the secondary structure of the membrane interacts greatly with the main structure, and the common structure analysis of the whole structure should be carried out and the optimal design should be based on the analysis results.
