[关键词] 钢骨高强混凝土 短柱 配箍率 延性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.
Keywords: steel reinforced high-strength concrete; short columns; stirrup ratio; ductility
