采用杆系拱肋来加强单层柱面网壳的结构体系是一种新的拱──网壳杂交结构体系，本文对这种结构体系进行了非线性稳定分析，并与相应的未加强的单层柱面网壳进行了非线性分析比较。同时本文对有无加强拱的两种技面网壳进行了缺陷影响分析，并与试验结果进行比较。结果表明，杆系拱助对提高单层往面网壳稳定性的作用是显著的，同时由于杆系拱肋的加强作用，缺陷的影响也显著减小。 The use of rod-arch ribs to reinforce the structural system of single-layer cylindrical reticulated shells is a new type of arch-netshell hybrid structure system. This paper presents a nonlinear stability analysis of this type of structural system, and corresponding non-enhanced Single-layer cylindrical lattice shells were compared with nonlinear analysis. At the same time, this paper analyzes the defect effects of two kinds of lattice shells with or without reinforced arches and compares them with the test results. The results show that the effect of the rod-arch system on the stability of the reticulated shell on the single layer is significant. At the same time, due to the reinforcing effect of the rod-arch ribs, the influence of the defects is also significantly reduced.
