［摘要］通过6个型钢再生混凝土组合柱的静载试验，对型钢再生混凝土组合柱轴压承载力进行了研究。试验主要考虑再生粗骨料取代率和长细比两个参数对构件承载力的影响。由试验得出组合柱在轴心荷载下的荷载位移曲线，分析型钢再生混凝土组合柱的破坏机理及再生粗骨料取代率、长细比对其轴压承载力的影响，提出型钢再生混凝土组合柱轴压承载力计算公式。

 Abstract:According to static experiment of six steel reinforced recycled aggregate concrete composite columns，the axial compression loadbearing capacity was studied. Two factors, which were the recycled coarse aggregate replacement rate and slenderness ratio, were taken into consideration. Loaddisplacement curves of composite columns under axial loads were obtained. The fracture of composite columns and the influence of recycled coarse aggregate replacement rate and slenderness ratio on axial compression loadbearing capacity were analyzed. The formula for axial compression load of steel recycled concrete composite column was also presented.

Keywords:steel reinforced recycled aggregate concrete; replacement rate; slenderness ratio; loadbearing capacity
