摘要
取柱端位移和对应的柱端力作为状态变量,利用传递矩阵和逐段分析的方法来分析多跨多层框架。文章取框架的每一层作为一个单元,建立基本单元端部的状态变量到相邻单元端部状态变量之间的转换关系。分析过程中,框架层数的增加仅增加矩阵相乘的次数,而待求的基本未知量的数目始终保持不变。
In this paper the nodal displacements and forces of bending bars are taken as state vectors.The method of transfer matrix and one story by one story are used to solve multi bay and multi story frames. With each story of frames as a basic element,the transfer relation of the end state vectors of an adjacent basic element is established.In analysis ,the increase of story number of frames only results in the increase of successive matrix multiplication,but the number of unknowns is not increased,so that the ability of computer solving problems is improved.
