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,通常采用分层法后按无侧移刚架用弯矩分配法求解。对分层后六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。
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 solutions for a section of frame with 6 spans were obtained by summing up the distributed and transferred moments with infinite rounds. The total moment on the end of one member which is easy to be obtained and is the closed solution wanted,is a sum of a infinite series with the common ratio less than one. The closed solution is expressed by distribution factors and transferred factors.
