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 reinforced high—strength concrete edge joints with the variable parameters ofthe fraction of steel fiber by volume(0．5％、1％、1．5％)and the ratio of stirrup(two rows of a diameter of8 ram、five rows of a diameter of 8 mm)in core zone，the hysteresis curve，displacement ductility and the work—ing index of the steel fiber reinforced high—strength concrete frame edge joint under the low cycles loading areinvestigated．The results show that the steel fiber can significantly improve the ductility and enlarge the energydissipation capacity of the high strength concrete frame joint．So the steel fiber will be conducive to anti—seismic structure and have asignificant effect on resolving the crowded conditions of the stirrups in core zone of thejoints and constructional conditions．
