[提要] 分析給出了異形柱雙向配筋的快速算法，明顯減少了求解中和軸的迭代次數(shù)，而且適用于不等肢長(zhǎng)、各類混凝土等級(jí)的異形柱配筋計(jì)算。按本方法編制的程序可滿足工程精度要求，且具有實(shí)用價(jià)值，已成功嵌入結(jié)構(gòu)分析程序中。

A rapid computer method for the reinforcement of the R.C.special-shaped columns subjected to biaxially eccentric loading is given. By this method, the iterative number to find the neutral axis is obviously reduced. lt can be used to the special-shaped columns with non-equal flanges and various concrete grades. Based on this method, a computer program has been developed, which satisfies the accuracy of the engineerings and has successfully joined into the structural analysis program for application.
Keywords: R C special-shaped columns; biaxially eccentric loading; reinforcement; neutral  axis
