摘要
多高层建筑框架在竖向荷载作用下的内力 ,在近似分析时 ,通常采用分层法 ,按无侧移刚架用弯矩分配法求解。该文对分层后的单跨、双跨与三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 。
The rigid frames of high rise buildings subjected to vertical loads are usually divided into several sections.Each section is considered no lateral displacement and solved by the moment distribution method.In this paper the closed soultions for a section of frame with 1 to 3 spans are obtained by summing up the distributed and carried over moments infinitely.The total moment on the end of one member is the sum of an infinite series with the common ratio less than one,which is easy to be obtained and is the closed solution wanted.The closed solution is expressed by distribution factors and carried over factors.
