摘　　要：通过 1 4根剪跨比λ为 2 0的试件在反复荷载作用下延性的试验研究 ,研究了钢骨高强混凝土短柱的破坏形态 ;分析了配箍率对钢骨高强混凝土短柱位移延性的影响 ,得出了延性和配箍率间的相关曲线 ;分析了配箍率对钢骨高强混凝土短柱轴压力系数的影响 。Through 14 test pieces under axial load and repeatedly horizontal load test,the displacement ductility and failure characteristics of steel reinforced high strength concrete (SRHC) short columns are studied.The influences of stirrup ratio on displacement ductility and the limited values of axial compression ratio of the SRHC short columns are also analyzed.The interrelated curves between ductility and stirrup ratio are obtained.The limited values of axial compression ratio of the columns are suggested, corresponding different stirrup ratios at a certain level of ductility.
