[提要]  通過(guò)14根剪跨比A為2.0的試件在反復(fù)荷載作用下延性的試驗(yàn)研究，研究了鋼骨高強(qiáng)混凝土短柱的破壞形態(tài)；分析了配箍率對(duì)鋼骨高強(qiáng)混凝土短柱位移延性的影響，得出了延性和配箍率間的相關(guān)曲線；分析了配箍率對(duì)鋼骨高強(qiáng)混凝土短柱軸壓力系數(shù)的影響，得出了滿足一定延性要求的對(duì)應(yīng)于不同體積配箍率的鋼骨高強(qiáng)混凝土短柱的軸壓力系數(shù)限值。

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
