| 摘 要： | 对计及膜力影响、受均布载荷的四周固支矩形加筋板组合结构进行了刚塑性大变形分析．首先对变形模态建立了判别条件；进而根据变形模态和塑性铰线的内能耗散获得了残余变形的估算公式．经实例计算，并与ＡＤＩＮＡ程序计算结果作了比较，获得了变形模态和最大残余变形值均相当一致的好结果．

| Abstract: | A rigid-plastic large deflection analysis is made for'a built-up structure with stiffened rectangular plates fully clamped around the periphery and subjected to a uniformly distributed load. The effect of the membrane force has been taken into consideration.The discriminants for the deflection modes is given. The formulae for the estimate of permanent deformation are derived from the denection mode and the internal energy dissipation of plastic hinge lines.The results of examples of calculation are compared with those obtained by ADINA program and found to be in fairly good agreement with the latter in both the deflection mode and the maximum permanent deformation. |
