| 摘 要： | 在平截面假定的前提下，推导了钢筋混凝土环形截面受弯构件正截面非均匀配筋的计算公式，并且应用MathCAD数学工具软件对某一环形截面均匀及非均匀配筋方式分别进行了不同弯矩作用下的配筋计算。计算结果分析表明，《混凝土结构设计规范》（下简称《规范》）简单套用偏心受压构件的计算公式是不妥的；所推导的新计算公式，补充完善了《规范》中环形截面正截面受弯构件强度计算的内容。

| Abstract: | Based on presumed plane-section, formulas of non-uniform reinforcement for normal section of flexual members with ring section were deduced. Using the MathCAD program, uniform and non-uniform reinforcements of a ring section under different moments were calculated. It is indicated that simply adopting the calculation formula for eccentric flexural members in the Code is not efficient; that the newly deduced formula complements the strength calculation of normal-section flexual members. |
