| 摘 要： | 从建立结构变形前的几何方程入手,然后通过对方程中所包合的各杆长和约束所允许产生位移的节点坐标进行变分运算,即可得到解起静定桁架问题时所必需的变形几何方程。此种建立起静定桁架问题的变形几何方程的解析方法,简单,易行,与常用的变形几何图解法是并行不悖的。

| Abstract: | This paper, at first, sets up the geometry equations of predeformation, then follows variation cal-culus to lengths of each rods and knot coordinates of displacements permitted by limitations at lastobtains the deformation geometry equations of solving statically indeterminate truss necessarily.This analytic method of building statically indeterminate truss deformation geometry equations issimple, easy, and not contradictory contrast with deformation geometry diagram method in com-mon use. |
