摘　　要：研究了复杂空间结构体系的整体稳定性能。利用ANSYS程序的非线性分析功能对上海浦东机场二期工程中的候机长廊结构进行了多种荷载组合下的稳定性分析,得到各组合下的屈曲荷载因子、屈曲特征、屈曲模态及不同因素的影响。对这些结果的比较可知,结构的整体稳定分析是必要的,结构的初始缺陷、几何非线性、材料非线性对结构整体稳定的影响很大,分析时不宜忽略。Overall stability of a complex spatial structure is studied in this article. Using the nonlinear methods of the ANSYS procedure, the stability of the gallery of Pudong International Airport in the Second Phase under several different Load combinations is analyzed, and load factors, buckling modes, buckling characters and other different factors are obtained. From the comparison among the results, it can be concluded that the structural overall stability analysis is necessary, and the initial defects, geometrical nonlinearities and material nonlinearities, which have important effects on the structural stability, should be considered in the analysis.
