摘要

摘要: 相比于实心钢筋混凝土柱，空心钢筋混凝土柱具有自重轻和截面扩展好等优点，被广泛地用作桥墩，由此其不可避免地会受到船舶的撞击。本文中进行6根内八边形空心钢筋混凝土柱和4根内衬八边形钢管空心钢筋混凝土柱的动力响应的实验。在实验中记录了构件破坏形态、撞击力时程曲线和跨中位移时程曲线，并从撞击高度、边界条件和钢板厚度等方面分析了构件的耐撞性能。结果表明：内八边形钢筋混凝土柱和内衬八边形钢管空心钢筋混凝土柱在撞击荷载作用下的破坏形态主要分为两种破坏类型，分别为局部型破坏和整体型破坏；撞击高度越大构件破坏越严重；两端固定对构件的耐撞击性能有提升作用；钢管厚度对构件的耐撞击性能有较明显的提升作用。

Abstract: By comparing with their solid reinforced concrete columns counterparts, the inner hollow reinforced concrete columns are widely used as piers because of their advantages including light weight and good section extension. These piers will inevitably be hit by ships. In this paper, dynamic response experiments of six inner octagonal hollow reinforced concrete columns with and without steel tube are carried out. The failure mode, the impact force- versus-time curves and trans-middle displacement-versus-time curves were recorded. The impact resistance of the component is obtained by analysis of the impact height, the condition of the boundary and the thickness of the steel tube The experimental results show that failure modes of inner octagonal hollow reinforced concrete columns under lateral impact load can be divided into two categories: local failure (type I) and global failure (type II). As the height of impact increases, the damage seriousness of the component increases. Fixing two endings of the component can improve its impact resistance. The thickness of the steel tube has an obvious effect on the impact resistance of the component.
