摘要
分析了对称配筋矩形截面小偏心受压构件采用规范近似算法的误差来由;将牛顿-秦九韶法用于计算此种构件,从而提高了精度,且运算公式颇为简便。
This article analyses the reasons of the errors in calculating members in micro eccentrical cornpression of symmetrically reinforced rectangular cross section with regular approximate method. Newton Qin Jiu Shao′s method, whose calculation formula is simple, is used so that the level of accuracy is raised.
