摘　　要：依据梁 柱单元非线性有限元理论 ,编制了网壳结构几何非线性分析程度 ,分析了不同矢跨比、不同双层杆件布置区域的两种跨度的局部双层网壳的静力、稳定特性 ,比较了变化规律 ,确定了不同矢跨比下 ,单层网壳边界处布置双层杆件的合理范围。Based on nonlinear finite element theory of beam column element,the geometrically nonlinear static stability analysis program was made.With this program the static stability behavior of partial double layer reticulated shell is studied at different height span ratio and different range for two span laying double layer members.The rational range for laying double layer members is determined,which can be as a reference to similar structure design.

关 键 词：结构设计 局部双层网壳 几何非线性 静力 稳定
