Abstract

Fibre reinforced concrete (FRC) is a well-known solution for industrial floorings, tunnelling or specific other applications since decades and its use is extending towards a broader range of structures. It can act either as a complement to conventional bar reinforcement or, for specific cases, even as a substitute to it. Fibres are added to concrete firstly to enhance its tensile behaviour but can bring other substantial benefits. In particular, high-strength steel fibres have a considerable impact even when added in moderate quantities to the concrete mix, therefor with reduced additional cost.This paper will investigate the potential of steel fibre reinforced concrete in the field of steel- concrete composite structure, a combination which is still vastly unexplored. The case of encased composite bridge sections (filler beam decks according to Eurocode 4) will be analysed by numerical simulations. The results show benefits in term of ultimate limit state, serviceability limit state as well as durability. This preliminary study serves as guidance for future experimental campaign.
使用纤维增强混凝土填充梁段-结构优化的潜力
几十年来,纤维增强混凝土(FRC)是一种众所周知的工业地板、隧道或其他特定应用的解决方案,其用途正在向更广泛的结构领域扩展。它既可以作为常规钢筋的补充,也可以在特定情况下作为替代。首先将纤维添加到混凝土中以增强其抗拉性能,但可以带来其他实质性的好处。特别是,高强度钢纤维即使在混凝土混合物中加入适量也有相当大的影响,从而减少了额外的成本。本文将探讨钢纤维混凝土在钢-混凝土组合结构领域的潜力,这是一种尚未开发的组合。将通过数值模拟分析封闭式复合桥梁截面(根据欧洲规范4的填充梁甲板)的情况。结果表明,在极限状态、使用极限状态和耐久性方面均有较好的效果。本初步研究为今后的实验活动提供指导。
