摘要
一个平面汇交力系的平衡条件是其力多边形必须闭合,依其条件,利用图解法和计算机中的AUTOCAD绘国工具,迅速准确地求解一个结点上的两个未知力,并以其类推求解桁架各杆内力。特别在复杂的输架内力计算中更显示其法优越性。
The halancing condition of plane joint-force system is that force polygon must be ciosed. The graphic solution and AUTO CAD tool of computer can be applied to obtain two forces on a nodepoint fast and accurately, then internal force of truss can be obtained. This computation method of internal force has its suPeriority,especially for a complicated truss.
