[提要]  根据钢筋砼异形截面双向偏心受压柱的工作机理，编制了正截面承载力分析的数值迭代法计算机程序，并用它对T形.L形截面各1 024根柱进行了计算分析，总结了这两种截面双向偏心受压柱正截面承载力的变化规律，在此基础上提出双向偏心受压柱正截面承载力的简化计算公式，并给出了利用此公式进行T形、L形正截面设计的计算机程序，可用于实际工程设计。

Based on the behavior of R.C. special-shaped columns subjected to biaxially eccentric loading, a computer program for exact analysis of load-bearing capacity on the basis of numerical iteration method is compiled. By using this computer program, 1 024 T and L shaped columns analyses are achieved, and then the variation regularity of load-bearing, capacity for T and L shaped columns is summarized. A simpMed calculation method for determination of load-bearing capacity of T and L shaped columns is proposed, and the corresponding calculation program, which is of practical engineering value, is compiled.
Keywords: R.C.special-shaped column;  load-bearing capacity;  simpMed calculation method;  numerical iteration method
