摘　　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 １０２４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-beating, capacity for T and L shaped columns is summarized. A simplified 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.
