| 摘 要： | 采用数值积分方法模拟计算了轴心受压铜骨-铜管高强混凝土组合柱的荷载-变形关系曲线，计算结果与试验结果吻合良好．在此基础上通过大量计算，研究了套箍指标、配骨指标、长细比和偏心距对组合柱承载力的影响．计算分析表明，铜管、铜骨和混凝土的协同工作，可有效地提高柱子的承载力．

| Abstract: | The numerical method is applied to simulate the curve of the load-deformation of the axially loaded circular steel tube column filled with steel-reinforced high-strength concrete. The numerical results agree well with the experimental data. Based on the numerical results, the effects of the confinement index, the section steel index, slenderness ratio and eccentricity on the bearing capacity of the composite column are discussed. Numerical analyses show that the bearing capacity of this kind of composite column can be improved greatly because of the interaction among steel tube, section steel and high-strength concrete. |
