摘要: 多螺旋箍筋能够显著提高矩形混凝土柱的轴压承载力。该文采用有限元方法分析了多螺箍筋约束对矩形混凝土截面应力分布和幅值的影响。采用试验数据对多国规范的约束混凝土柱轴压计算方法进行了分析验证，分析了不同计算方法引起承载力计算结果出现差异的因素。基于数值分析结果，推导了适用于多螺旋箍筋柱的轴压承载力计算公式，其中不同部位的混凝土根据约束条件采用不同的约束混凝土本构。试验结果的对比分析表明该方法具有更高的计算精度。Abstract: Axial bearing capacities of rectangular concrete columns can be significantly improved by the confinement of multi-spiral hoops (MSHs). The confining effect of multi-spiral hoops on the stress distribution and amplitude of concrete cross section was analyzed by the finite element method. Subsequently, the calculating methods for the axial bearing capacity of rectangular concrete columns in various codes were validated by test data. The deviation of the calculated results of different methods was also analyzed. Based on the results of numerical simulations, the axial compression calculation formulas for MSH confined columns were proposed, and different stress-strain laws were considered for different parts of the concrete cross section. The comparison of test results showed that the theoretical calculation method had better accuracy.
