Abstract

<p>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.</p><p>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.</p>
