| 摘 要： | 多高层建筑框架在竖向荷载作用下的内力近似分析时，通常采用分层法，按无侧移刚架用弯矩分配法求解。本文对分层后四跨刚架用弯矩分配法对结点的不平衡力矩进行无数次分配传递，求得无数次分配弯矩和传递弯矩之和，得闭合解。

| Abstract: | The rigid frames of high-rise buildings subjected to vertical loads are usually divided into several layers.Each layer is considered no lateral displacement and solved by the moment distribution method.In this paper the closed solutions for a layer of frame with 4 spans are obtained by summing up the distributed and carried over moments infinitely. |
