| 摘 要： | 将广义协调元用于求解薄板大挠度问题。编写了专用程序GCEP并计算了四边简支、四边铰支和四边固定方形薄板在横向均布荷载作用下的跨中挠度。计算结果表明,广义协调元对于求解结构几何非线性问题同样具有精度高、收敛快等优点。

| Abstract: | In this paper, the generalized conforming element is used to treat the problem of large deflection of thin plates. A special computer program GCEP based upon the element has been written and used to calculate the central deflections of square plates with four simply supported, hinged and rigidly clamped edges under uniform lateral load. Numerical results indicate that the generalized conforming element has the advantages of high accuracy and uniform convergence to geometrically nonlinear problem of structures. |
