Application of high‐performance fibre reinforced concrete to precast girders for road bridges: Conceptual considerations and numerical analyses

High-performance fiber-reinforced concrete (HPFRC) can be considered a promising material for the construction of precast girders road bridges. This paper presents conceptual considerations and numerical analysis to support this statement. The HPFRC is compromised alternative between FRC UHPFRC mixes. Specifically, tailor-made mix design jointly developed by ACCIONA authors presented, then compared with other types concretes collected from technical literature. In addition, some trends observed in database are described. characterization followed advantages application proposed bridge case 60 m-span box girder analyzed.
