摘 要: 以再生粗骨料替代率为基本参数,对圆钢管再生骨料混凝土柱进行拟静力试验,获得钢管再生骨料混凝土柱在水平地震荷载作用下的破坏形式、滞回性能、骨架曲线、延性系数、耗能性能及刚度退化规律,分析钢管再生骨料混凝土柱的抗震性能。 Quasi static test was carried out to recycled concrete filled circular steel tube columns.The fracture mode,hysteresis property,skeleton curves,stiffness degeneration curves and energy dissipation property of recycled concrete filled circular steel tube columns were obtained for different coarse aggregate substitution rates.The aseismic performance of recycled concrete filled circular steel tube columns was analyzed.
