本文提供一个解算双阶柱计算长度的简捷计算法。数学模型系以对图解法几何图形的解算为依据,并以逐步逼近计算法求解。本方法较之于解算稳定临界方程,特别是当柱顶与弹性横染连按时,更为简便,计算结果可满足同样的精度要求。文中并提供了计算流程图。 This article provides a simple calculation method that solves the length of a two-stage column calculation. The mathematical model is based on the solution of graphical geometry and is solved by a stepwise approximation algorithm. This method is more convenient than solving the stability critical equation, especially when the top of the column is coupled with the elastic transverse dyeing, and the calculation result can satisfy the same accuracy requirement. The paper also provides a flow chart for the calculation.
