阶梯柱压弯的传递矩阵法

Transfer Matrix Method for the Compressed Bending with Steppe Columns

介绍了阶梯柱压弯的传递矩阵法。具体做法是首先将阶梯柱分成单元，然后对单元进行受力分析和变形分析，得出了反映这一物理现象的常系数的线性微分方程。最后利用该方程的初参数解构成传递矩阵（其它单元进行类似的分析）。这里介绍的传递矩阵法，采用矩阵形式表达，使求解问题大为简化，亦适用于上机计算。

The transfer matrix method the the compressed bendings with stepped columns is introduced. At first,the stepped columns are divided into many elements,then force and deformation of all the elements are analysed and a linear differential equation with constant coefficients for reflecting the physical phanomena is obtained,a transfer matrix is construces by using the initial parametric solution of the differential equation finally.The transfer matrix method is expressed in the form of the matrixes,which greatly simplifies the solution of the compressed bendings with stepped columns and is suitable for the calculation by the computers.
