本文根据大跨度单层柱面网壳易失稳的特点，在柱面网壳的适当部位加设杆系加劲肋后，有效地提高了其稳定性，并减小了其水平推力。对带肋与不带肋单层柱面壳结构模型的大位移、非线性稳定分析与比较则表明，杆系拱肋对单层柱面壳结构的稳定是显著的。缺陷影响分析结果表明，初始缺陷对带肋柱面壳结构的影响比不带肋单层柱面壳结构的影响要小。
In this paper, according to the characteristics of the large-span single-layer cylindrical reticulated shell which is easy to destabilize, after adding the rod-type stiffeners in the appropriate part of the cylindrical reticulated shell, the stability is effectively improved, and the horizontal thrust is reduced. The analysis and comparison of the large displacement and nonlinear stability of the ribbed and non-ribbed single-layer cylindrical shell model show that the stability of the single-layer cylindrical shell structure is significant. The results of defect impact analysis show that the effect of initial defects on the ribbed cylindrical shell structure is smaller than that of the non-ribbed single layer cylindrical shell structure.
