摘　　要：利用 14根剪跨比λ =2 0的试件对钢骨高强混凝土 (SRHC)短柱的抗震性能进行了试验研究 ,分析了轴压力系数、配箍率对钢骨高强混凝土 (SRHC)短柱位移延性的影响 ,分析了短柱的主要破坏形态。并得出了影响因素和位移延性间的关系曲线。根据试验结果 ,在满足一定延性的基础上 。The experimental study on seismic performance are carried out through 14 steel reinforced high strength concrete (SRHC) short columns.The main factors such as axial compression ratio,stirrup ratio, which affect the ductility of SRHC short columns,are analyzed.The interrelated curves between ductility and affecting factors are obtained.The failure characters of SRHC the short columns are also analyzed.The limit values of axial compression ratio of SRHC short columns are reached,which satisfy a certain requirement of ductility.
