【摘要】 取杆端位移和对应的杆端力作为状态变量，利用传递矩阵和逐段分析的方法来分析多层框架，并建立了单跨多层框架的传递矩阵。在分析过程中，框架层数的增加只增加计算过程中的矩阵相乘的次数，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。更多还原

【Abstract】 Taking the nodal displacements and forces of column as state vectors,transfer matrix methods are used to analyse multi story frames.The transfer matrix of multi story frames is established.In the procedure of analysis,the increase of story number of frame only brings about the increase of successive matrix multiplication,number of unknowns is not increased throughout.Therefore, the computer efficiency of solving problems is raised.更多还原
