摘　　要：黑瞎子岛植物园温室采用大跨单层网壳结构。温室网壳除满足结构所需的强度、刚度外,其整体稳定是计算分析重点。通过单、双非线性整体稳定分析,证明矢跨比较小的单层网壳结构整体稳定分析指标是其设计的控制指标。A long span single-layer latticed shell structure is used in the botanical garden on the Black Bear Island.Stability analysis of such a latticed shell is the key in structural design besides its strength and stiffness requirement calculations.This paper verified that the integral stability analysis is a critical design process for small single-layer reticulated shell structures through the single nonlinear stability and the double nonlinear stability analyses.

关 键 词：单层网壳结构 大跨 矢跨比 非线性稳定性分析
