【摘要】 通过4根大尺寸薄壁钢筋混凝土管柱在低周反复水平加载试验,得到了大尺寸薄壁钢筋混凝土管柱的滞回曲线和骨架曲线;并分析了轴压比、配筋率、壁径比对试件的滞回性能、耗能能力、延性的影响;结果表明,大尺寸薄壁钢筋混凝土管柱具有良好的抗震性能。更多还原

【Abstract】 Based on the experiment of 4 large size thin-walled reinforced concrete pipe columns(RCPC) subjected to low cyclic reversed lateral loads,the hysteretic curve and skeleton curves of large size thin-walled reinforced concrete pipe columns are obtained;and the influences of ratio of axial compression stress to strength,reinforcement ratio and thickness on the hysteretic property,energy dispassion and ductility of samples are analyzed.The tests prove that large size thin-walled reinforced concrete pipe columns can provide good aseismic behaviors.更多还原
