摘要
本文应用悬臂梁计算杆端位移的公式及有关的平移旋转公式,依据刚架内由杆件组成的回路中的节点位移和杆端内力、外荷载之间应有确定的关系的原则,给出按回路校验空间刚架的解的方法,并对若干常见的回路给出可直接用于校验的回路方程。
This article gives a method of checking the solution of the rigid space framework by means of applying the formula which is used to calculate the deflection at the end of the member with cantilever beam as well as the translation and rotation formulae. This bases on the principle that there should be a definite relation between the joint deflection in the loop formed by the members of the rigid framework, and the internal force at the end of the member and the external load. A loop equation which can be applied directly to checking is also given for some normal loops.
