钢筋混凝土环形截面构件受弯时强度计算

Strength Calculation of Annular Section of Reinforced Component in Bending

空心圆形电柱在安装时可能受到弯曲作用，其强度计算，是在做了合理假定后推导力学方程式。求解方程式并非易事，即使使用计算机也只是试算求解，或采用图解法。本文给出求解联立方程组的计算方法。

When installed ,the hollow pole may be bending.The strength could be calculated from mechanical formula due to hypothesis,and it is very difficult by means of computer.The trial and error or graphic method were usually used.This paper introduced a method of solving simultaneous equations.
