本篇叙述分析連續梁及連續架的影響公式法。其法係令單位力矩分別作用於各個可勤結點作一個循環的力矩分配,求得各桿端撓矩之影響公式。由於此後各循環所得結果必係漸小的幾何級數,故可將此等撓矩以相應的常數除之,再加以原有的定端力矩,即得各桿端的實際撓矩,此外並略述如何利用此法,以求可動結點之侧傾。 This article describes the analysis of the influence formula of continuous beams and continuous frames. Its law makes the unit moment acting on each workable node to make a cycle of torque distribution, and obtain the influence formula of the bending moment of each rod end. Since the results obtained after each cycle must be a geometric series of progressively smaller, it can be divided by the corresponding constant, and then the original fixed end torque, that is, the actual bending moment of each rod end, in addition to Describe how to use this method in order to find the roll of the movable node.
