摘要
分别介绍了桁架中L形结点,T形结点,X形结点,K形结点等特殊结点的各种零杆的快速判断方法,并结合具体实例进行了分析,指出零杆的判断对于桁架的内力求解有很大帮助,能够使后续的分析计算变得更加顺畅。
This paper respectively introduced fast judging method of various zero-poles,especially some special node,such as the L-shaped truss nodes,T-shaped junction,X-shaped junction,K-shaped junction,made an analysis by combining with examples.Then it pointed out that judgment for the truss rod is of great help to solve the internal forces,which can make the follow-up analysis and calculation more smoothly.
