摘　　要：本文运用非线性有限元全过程分析方法 ,结合新建的成都双流机场候机楼屋面大跨度单层柱面网壳 ,对弹性支承的大跨度单层柱面网壳结构的稳定性进行了分析 ,对比了不同支承条件、不同矢跨比和不同杆件截面对弹性支承的单层柱面网壳稳定性的影响 。Based on the geometrically nonlinear finite element method and the postbuckling analysis technique, numerical analyses are performed on the stability behavior of a real braced barrel vault supported on frames. The effects of some factors on the stability of single layer braced barrel vaults are investigated, including supporting conditions, rise to span ratios and cross sectional areas of members. Results from this study can be used in practical design.
