摘　　要：根据梁 -柱单元非线性有限元理论 ,采用弧长法与修正Newton -Raphson法相结合的迭代法 ,编制了网壳结构几何非线性分析程序 ,对不同矢跨比下单层网壳和局部双层网壳的静力稳定性能进行分析比较。Based on nonlinear finite element theory of beam-column element,the geometrically-nonlinear static stability analysis program was made in which the iteration method of modified Newton-Raphson method with Arc-length method is used.With this program the stability of single layer reticulated shell with four types of height to span ratio is compared with partial double layer reticulated shell.The resules provides the reference for the similar structures design.

关 键 词：几何非线性分析 局部双层网壳 失跨比 梁-柱单元 静力稳定性能
