本文的主要目的是建立求解连续梁支座弯矩精确而简洁的计算公式,实用于任意荷载作用下的等跨或不等跨连续梁的计算。其公式形式如下所示:M_i=M_i~右+ΣX· (1)从(1)式中可以看出:支座弯矩公式中包含有两类不同性质的项,一类是与荷载有关的单跨梁固定端弯矩,另一类是与各跨旋转刚度有关的形常数。前者可以用现行计算图表解决,后者是本文所要解决的问题,
The main purpose of this paper is to establish a precise and concise formula for solving the moment of continuous beam bearings, which is applicable to the calculation of continuous or unequal span beams under any load. The form of the formula is as follows: M_i = M_i ~ right + ΣX (1) From (1), it can be seen that the bearing moment formula contains two types of items of different nature, The bending moment of a single span beam is fixed, and the other is the shape constant related to the cross-rotation stiffness. The former can be solved with the current calculation chart, which is the problem to be solved in this article,
