小偏心受压构件对称配筋截面设计的简化方法

Approximation Method for Section Design of Symmetric Reinforcement for Compression Members with Small Eccentricity

该文通过对钢筋混凝土矩形截面小偏心受压构件对称配筋计算公式中关键因子ξ(1?0.5ξ)的线性化,提出了一种求解二次方程获得的ξ近似方法,降低了设计工作的难度。

Through linearizing the key factorζ（1-0.5ζ）in the mathematics formula of symmetric reinforcement for compression members with small eccentricity, this article proposes an approximation method of calculating ζ by using second order equation be present, which could ease the work of designers.
