卡尼迭代法的改进

Method of Moment Distribution and Carry Over

计算有侧移框架内力的力矩分传法。是融侧移计算于角位移计算之中,其特点是因角位移引起的分传力矩及线位移引起的侧移力矩均可通过结点待平衡力矩求得。后者还可用同一楼层各结点待平衡力矩之和进行计算。

This paper presents a new internal force calculation method of a frame with lateral dis- placement.This method combines the calculation of angular displacement with the calcu- lalion of lateral displacement.Its characteristic is that,both the moment due to angular dis- placement and the moment due to lateral displacement are calculated by the same unbalanced moment at a node.For simplicity,the moment due to lateral displacement can be computeed by the sum of the unbalanced moment of the nodes on the same floor.
