| 摘 要： | 为了从配箍特征值的角度来研究钢筋混凝土异形柱的轴压比限值及其配箍构造，采用非线性分析的方法，对12960根异形柱截面的延性进行了电算分析，得到了与配箍特征值相关的异形柱的轴压比限值，然后分别从纵筋压曲和约束混凝土2个方面来分析箍筋配置对异形柱延性的影响，得到了异形柱的配箍构造要求．

| Abstract: | To research limited value of axial compression ratio and detailing requirements for stirrup of special RC shaped column from the point of characteristic value for providing stirrup, the ductility of 12 960 special shaped columns was calculated and analyzed by nonlinear method. The limited value of axial compression ratio of special shaped column in relation with characteristic value for providing stirrup was obtained. Then the effect of the stirrup arrangement on the ductility of special shaped RC columns was discussed from buckling of longitudinal reinforcement and constraint concrete, and the detailing requirements for stirrup of special shaped RC column was given. |
