摘　　要：通过对8个钢管再生混凝土轴压短柱以及2个钢管混凝土轴压短柱进行试验研究,比较了钢管再生 混凝土与钢管混凝土的荷载-变形关系曲线和强度承载力关系．采用数值方法计算了构件的荷载-变形曲 线,计算结果与试验结果吻合良好．采用有关设计规程对钢管再生混凝土的强度承载力进行计算,分析了 各规程在计算钢管再生混凝土轴压强度承载力时的适用性．Experiments on eight recycled concrete - filled steel stub columns as well as two concrete -filled steel stub columns subjected to axial loading were carried out. The relationships of load - deformation curves and loading capacity between recycled concrete - filled steel tubes and concrete - filled steel tubes were compared. The load - deformation curves calculated by numerical method indicate good agreement with experimental results. By using current design codes to calculate the loading capacity of recycled concrete - filled steel tubes, the applicability of different codes in calculating loading capacity of recvcled concrete - filled steel tubes were discussed.
