钢筋砼连续梁优化设计的弯矩分配法

A Moment Distribution Method for Optimal Design of R.C.Continuous Beam

本文首先给出了用各跨最大变矩、最大剪力或跨度表达的单跨钢筋砼梁最优刚度，然后基于分部优化法提出了钢筋砼连续梁优化设计的弯矩分配法，对节点的不平衡弯矩按内力或跨度表达的最优刚度进行一次弯矩分配，手算和电算都很简捷方便。

In this paper,the optimum rigidity of one-span reinforced concrete beam is given by using maximum moment, shear or span. Then based on the concepts of divisional optimization a moment distribution method for oprimal design of R. C. continuous beam is put forward. The primary moment distribution is made for the joint' s unbalanced moment according to the optimum rigidity expressed by internal force and span. It's simple and convenient to calculate by both hand and computer.
