摘　　要：本文对菱形平面单块扭壳的曲面特性进行研究，求得曲面方程式，然后按壳体薄膜理论求内力，同时按壳体有矩理论，采用有限元法作内力及位移的数值计算，编制了薄膜内力、弯矩、扭矩及挠度的数值计算表，文中附有工程实例，可供设计参考。Abstract The property of ctirved surface of the twisted shell with bottom of rhombus is studied in this paper,the equation of the camber is derived.The internal forces are calculated by the theory of thin membrane firstly,then the internal forces and displacements are computed by FEM on the basis of the theory of moment.The tables of internal forces and displacements are formed at last,and an example is shown for reference in designing.
