| 摘 要： | 本文根据扁壳的弯矩理论讨论了矩形底球面扁壳的解析解。给出的内力及位移分量的表达式可用来考虑连续壳体的边界影响。解析解采取单级数形式。通过数值计算的结果分析,证明解的收敛性较好,可满足工程设计的要求。已编制了输入数据简单且勿需较大内存的微机通用程序。

| Abstract: | This paper presents a study on the analytical solution of continuous shallow spherical shells under uniform distributed load, refering to the bending theory of shallow spherical shell, the stress function and the displacement functions u,v,w are proposed to satisfy the partial differential equations and to prescribe the various boundary conditions.Through several numerical examples, the convergence of series is discussed and accuracy of solution is verified by checking the equi librium condition between the surface load and the internal forces acting at the edges of a shell.A program for the analysis of rectangular shallow spherical shells continuous in one direction is prepared for rapid calculation in a minicomputer. |
