| 摘 要： | 根据钢筋砼双向压弯柱的工作机理，提出了用全过程非线性分析来研究双向压弯柱截面延性的方法，并编制了相应的计算机程序。通过对７３３根Ｌ形柱、７３３根Ｔ形柱和２４３根方形柱电算结果的分析，总结了Ｌ形、Ｔ形、方形截面双向压弯柱的截面延性规律，提出了这三种截面双向压弯柱的截面延性计算公式，并在此基础上，对轴压比、箍筋间距等一系列构造要求提出了设计建议。

| Abstract: | A method for the nonlinear analysis of complete response process for ductility of R. C. columns subjected to biaxially eccentric loading is presented. According to analytical results of 733 sets of L -shaped columns, 733 sets of T-shaped columns and 243 sets of square columns, the ductile behavior of R. C. L-shaped, T-shaped and square columns are investigated. The calculation formulas for ductility analysis of R. C. columns with three kinds of sections are suggested. On the basis of analysis, a number of design suggestions related to axial compression ratio and the spacing of stirrup are also proposed. |
