本文介绍的传递矩阵法以单根竖杆为计算单元,楼层为循环单元,杆底端的内力和变形为未知量.用逐层传递的方式,反映了结构刚度、几何约束以及荷载等沿高度不连续的变化。用它分析高层建筑框架和框-剪结构,建筑层数增加只是增加计算过程中的传递次数,未知量数始终保持不变。从而提高了计算机的分析能力。
The transfer matrix method introduced in this paper uses a single vertical rod as the calculation unit, and the floor is a circulating unit. The internal force and deformation at the bottom of the rod are unknown. The method of layer-by-layer transmission reflects the structural rigidity, geometric constraints, and loads along the height. Continuous changes. It is used to analyze high-rise building frames and frame-shear structures. The increase in the number of building floors only increases the number of transmissions in the calculation process, and the unknown quantity remains unchanged. This improves the computer’s analytical capabilities.
