摘要:
以5个钢纤维高强混凝土边节点试件为研究对象,以节点区钢纤维体积率(0.5%、1%、1.5%)和钢筋配箍率(2排φ8、5排φ8)为变化因素,研究了低周反复荷载作用下钢纤维高强混凝土框架边节点的滞回曲线、位移延性和功比指数.结果表明,钢纤维的掺入能够显著改善高强混凝土框架节点的延性,提高框架节点的能量耗散能力,有利于结构抗震,对于解决节点区的箍筋密集和改善施工条件有显著效果.
Abstract:
Taking five steel fiber high-strength concrete side node specimens as the research object, the hysteresis curve, displacement ductility and power ratio index of steel fiber high-strength concrete frame edge joints under low cycle repeated loading were studied by taking the steel fiber volume ratio (5.0%, 5%, 1.1%) and steel bar stirrup ratio ratio (5 rows φ2 and 8 rows φ5) as the changing factors. The results show that the incorporation of steel fiber can significantly improve the ductility of high-strength concrete frame joints, improve the energy dissipation capacity of frame joints, and be conducive to structural seismic resistance, which has a significant effect on solving the stirrup density and improving the construction conditions in the node area.
