摘要
本文对小偏心受压构件的配筋计算做了分析.对于非对称配筋构件,经过分析后认为,应当先选定A_s值而后进行计算.对于对称配筋,在需要求解ξ■的三次方程时,本文提出用牛顿切线法求解,比较方便。
The calculation of longitudinal steel of compression member with small eccentricity is analysed in this paper.For the member reinforced with unsymmetric steel,on the basis of analysis the paper points out that the calculation should be conducted after selection of steel area A_s.For the member reinforced with symmetric steel,it is appropriate to use Newton's tangent method to solve the 3^(rd)degree equation of ξ.
