摘　　要：网壳结构的稳定性是单层网壳结构分析中的一个关键问题.利用有限元程序SAP2000对跨度40m,矢高20m的单层网壳在全跨均布荷载作用下的线性和非线性稳定承载力进行了探讨分析.以两个工程计算实例为背景,通过线性分析和几何非线性分析研究了单层网壳结构的稳定性能,这些分析结果将对今后网壳结构的广泛应用有指导意义.The stability of lattice shells is a key issue for single-layer lattice shells.Using the finite element software SAP2000,the linear and nonlinear stability bearing capacity of the single-layer lattice shell which has the span of 40m and the vector height of 20m,is discussed and analyzed under a full-span uniform load.Through the linear analysis and geometric nonlinear analysis.the stability of single-layer shell structure is investigated with two engineering examples as the background,These results may be helpful for the wide use of lattice shells in future.
