| 摘 要： | 通过对异形柱在双向偏压状态下正截面配筋计算过程中中和轴变化规律的分析，提出了一种快速迭代方法．该方法能明显减少求解中和轴的迭代次数，而且适用不等肢长的、各类砼强度等级的异形柱配筋计算，该方法既保持了较高的计算精度，又大大提高了计算速度，为直接应用数值积分法开发设计软件提供了理论基础，已成功应用于配筋分析程序中．

| Abstract: | A rapid reinforcement method is given by researching the variation regularity of neutral axis of special-shaped columns,subjected to axial compression and biaxial bending.The iterative number to find the neutral axis is obviously reduced.It can be used to the special-shaped columns with non-equal flank and (various) concrete grade.The method shortens the calculation time under keeping the calculation accuracy,and has been jointed to the reinforcement program for application. |
