| 摘 要： | 本文提出了一种边界位移线性变化的矩形平片的五力模型，它既具有不包含刚体位移及未知量减少至最低限度的优点，又保证了相邻平片之间位移的连续性，适用于索－膜组合体系的力学分析及形状判定问题，也适用于空间组合网架的力学分析问题。

A CONFORMING FIVE-FORCE MODEL OF RECTANGULAR FLAT PANEL IN CLAD CABLE STRUCTURES |
| |
| Abstract: | A five-force model of rectangular panel is proposed with the displacements varying linearly along its sides.The model possesses the advantage that it includes the least number of unknowns,and at the same time ensures the continuity on the boundaries between adjacent panels.This model is applicable to form-finding and analysis of clad cable structures, as well as to analysis of space frames composed of bars and panels. |
