高层框架分析的状态变量传递法

Method of state vector transfer in analysis of tall frames

取高层框架柱端位移和对应的柱端力作为状态变量，利用传递矩阵和逐层分析的方法来分析高层框架。文中取框架的每一层作为基本单元，建立基本单元端部的状态变量与相邻基本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，从而提高了计算机分析问题的能力。

In this paper the nodal displacements and forces of column ends of tall frames are taked as state vector. The method of transfer matrix and one story by one story are used to solve tall frames. Each story of the frames is taked as a basic element. The transfer relation of the column\|end state vector of a basic element and the column\|end state vector of an ajecement basic element is established. In analysis the increase of the story number of the frame is only reduced to the increase of successive matrix multiplication, the number of unknowns is not increased. The ability of computer solving problems is raised.Key words:tall frames, state vector; transfer matrixorts resource in Liaoning, the current state of development of port and it's allocation, the characters of from develop of types of regional combination of ports, position of under region economic and discussion relevant to sustainable development of ports in Liaoning.
