摘　　要：本文讨论了超静定结构中求平面汇交二力杆系节点位移及杆件轴力的一种简单方法 ,避免了以往教材中通过绘制变形几何图确定杆系中各杆变形的困难与繁琐 ,使得处理此类问题更为简单。This paper introduces a simple solution to node displacement and axial force system of two-force rods of coplanar and concurrent forces in redundant structure,avoiding the difficulty and complexity to draw displacement geometrical chart in order to get each rod displacement in system of rod,and simplify and standardize displacement and axial forces through the use of the method in this paper.

关 键 词：超静定 平面汇交力系 二力杆系 变形 位移
