用比例法进行受弯构件正截面强度计算

The right section strength calculation of bending member using “ratio method”

在介绍现行受弯构件正截面强度计算的三种方法的同时 ,提出并阐述了“比例法”求解方法。用实例将该法与基本公式计算结果进行比较分析 ,证明该法具有易掌握、计算简便等优点 。

In this paper three methods of right section strength calculation for bending members in present are introduced. And according to basic formula and applicative law the 'ratio method' are proposed and discussed. The calculation results of this method and basic formula are compared. This method can be easily mastered and with simple calculating operation, which has widely applicative prospects.
