摘　　要：通过设计7根不同影响参数的圆钢管约束再生塑料混凝土短柱,来研究其在轴心受压作用下的抗压能力及性能的退化规律。通过试验得出试件的荷载-位移曲线,并分析圆钢管约束再生塑料混凝土短柱在轴压作用下的破坏状态、刚度退化以及能量耗散的过程,研究所得结果可为工程设计提供参考。Through the preparation of seven circular steel tube constrained recycled plastic concrete short column specimens with seven different plastics instead of fine aggregates and different concrete strengths,the degradation behavior of the compression resistance and performance under axial compression was studied.The load-displacement curves of the specimens were analyzed,and the failure state,stiffness degradation and energy dissipation of the circular steel tube constrained recycled plastic concrete short columns under axial compression were analyzed.The results obtained from the study can provide reference for engineering design.
