| 摘 要： | 基于等效夹层壳思想的双层网格扁壳非线性弯曲理论，采用伽辽金方法对双层球面网格壳体在均布压力作用下的非线性稳定性问题进行研究，得到了简支边界条件下双层球面网格扁壳的非线性载荷-位移关系式和临界屈曲载简的解析表达式，并讨论网壳结构几何参数对临界屈曲载荷的影响。

| Abstract: | Based on the nonlinear bending theory of double-deck reticulated shallow shells, the nonlinear buckling problem of sphere double-deck reticulated shallow shells under uniform transverse pressure is studied. An analytic solution for simply supported edges is obtained by using Galerkin's method. Numerical calculations are presented in diagrams to show the influence of geometrical parameters on the buckling behavior. |
