| 摘 要： | 对单层球面网壳进行了几何非线性稳定分析，利用一般空间梁单元的有限元分析，采用特征值屈曲分析预测结构的理论屈曲强度，再以弧长法对结构变形进行全过程跟踪分析，求得极限临界荷载．本文详细分析了40m跨度施威德勒型铝合金网壳在不同荷载作用下的稳定性，以及不同支承条件、不同失跨比对稳定性的影响．

| Abstract: | An analysis of nonlinear stability of single layer latticed domes has heen carried out based on fi-nite element analysis space beam element. Eigenvalue Buckling method is used to predict the theory buck-ling strength of construct and to obtain the buckling mode. Through arch-length method, the complete-process analysis of construct displacement is studied and the critical load obtained. The stability of singlealluminium alloy layer latticed domes under different loads and constrans is studied in details. |
