摘　　要：通过3根型钢活性粉末混凝土柱的轴压试验,研究型钢活性粉末混凝土柱在不同活性粉末混凝土强度等级下的轴压力学性能及其破坏特征。试验结果表明：型钢与活性粉末混凝土具有良好的协同工作能力;柱的极限承载力随着活性粉末混凝土力学性能等级的提高而提高;柱的最终破坏形态均以柱端部劈裂破坏为主。采用有限元分析软件ABAQUS对型钢活性粉末混凝土柱进行分析,有限元分析结果与试验结果吻合较好。The tests for 3 steel reinforced reactive powder concrete（ RPC） columns under axial compression were carried out. The mechanical properties and the failure characteristics were studied with different RPC strength grades.It was found from the experiments that the steel and the RPC were very well suited to collaborative work; the ultimate bearing capacity increased with increasing RPC grade; and its failure mode was characterized by the splitting cracks at the ends of the column. The finite element analysis software ABAQUS was adopted for the numerical modelling,and the numerical results agreed well with the experimental ones.
