Abstract:

通过5根高强箍筋约束超高性能混凝土(Ultra high performance concrete,UHPC)柱及4根普通箍筋约束UHPC柱的轴心受压试验,对其承载力、破坏形态、钢筋应变及应力-应变曲线进行了研究,并结合延性、韧性指数分析了体积配箍率、箍筋强度、箍筋间距及形式对约束UHPC轴压性能的影响。结果表明:所有约束柱均表现为延性破坏,高强箍筋可减轻约束UHPC的破坏程度;高体积率、小间距、形式复杂的高强箍筋约束UHPC,约束效率高,承载力及变形能力提高显著,轴压性能较理想;体积配箍率对轴压性能的影响程度大于箍筋强度;影响体积配箍率变化的因素中,箍筋间距对改善约束性能的贡献最大,依次是箍...
