本文提出用转移矩阵法来计算塔架和桅杆的内力、位移、稳定和振动。将结构顶部和底部的节点力和位移的关系通过转移矩阵来表达,并引用边界条件求解,最后得到各塔层的内力和位移。对一个横截面边数为n、尾数为m的塔架其基本未知量为6n个,与层数无关,而常用的矩阵位移法的基本未知量则为3mn个,两者相差m/2倍。因此采用本文方法时计算存储量可大大减少,从而可在小容量的计算机或计算器上进行。
In this paper, the transfer matrix method is used to calculate the internal force, displacement, stability and vibration of the tower and mast. The relationship between the nodal forces and displacement at the top and bottom of the structure is expressed by the transfer matrix, and the boundary conditions are used to solve the solution. Finally, the internal forces and displacements of each tower are obtained. For a tower with an edge number n and a mantissa of m in the cross-section, the basic unknown quantity is 6n, irrespective of the number of layers, and the basic unknown quantity of the commonly used matrix displacement method is 3mn, which is a difference of m/2 times. . Therefore, when using this method, the amount of storage can be greatly reduced, which can be performed on a small-capacity computer or a calculator.
