【摘要】 提出了一种快速的算法,该算法不仅判断出了中和轴法线角度在迭代计算中的旋转方向,而且给出了合理的的迭代初值,从而有条件引入两分计算方法,大大地缩小了中和轴法线角度的选择范围,以及减少中和轴的迭代次数,同时编制了计算机程序,进行了多种算例的计算,计算速度明显较快,配筋结果也更准确合理。更多还原

【Abstract】 A new rapid calculation method of the reinforcement of specially shaped columns is given in this paper.It gives the direction and the original value of the spin of the neutral axis’ normal line to reduce the scale and the interative number of finding the neutral axis by dichotomous method.Based on this method,a calculation program was developed,which has been used to calculate many examples with rapidly and accurateiy更多还原
