摘要: 使用《混凝土结构设计规范》(GB50010-010)公式(E.0.3-1)和(E.0.3-2)计算环截面钢筋混凝土受挠构件承载力时,受压区混凝土截面面积与全截面面积的比值α的变化域应予注意。将规范的这两个方程构建了两个全α域的表格函数,避免了设计截面时解超越方程的麻烦和试算的累赘。实例计算结果表明,建议的设计方法快速、简便,具有较好的实用性。

Abstract: In two formulas (E.0.3-1 and E.03-2) in the "Specifications of Concrete Structure Design, GB50010-2010) for the design of the flexural members with annular section, the ratios of the compression zone and the all section area   are complicated. The authors converted these two values into tables so that the trial and error process of solving the transcendental equations can be avoided. This paper also gives out an example to show the suggested method has the advantages of fast, simple and practical.
