以两个大尺寸单层球面网壳为例，分析了其荷载-挠度响应的全过程。本文首先研究了理想穹顶的非线性特性及其屈曲后各点的挠度形状。提出了两种缺陷分析方法。结果表明，单层球面网壳对初始缺陷非常敏感，本文提出的方法可用于真实的分析。
The whole process of load-deflection response is analyzed for two single-layer lattice dome of big size as practical examples. The nonlinear behaviours of the perfect domes and their deflection shapes at several points after buckling are at first investigated. Two methods for imperfection analysis are then suggested. It is proved that single-layer lattice dome is very sensitive to initial imperfections and the suggested methods can be applied to real analysis.
