Abstract: This paper presents the results of a study examining the effect of UHPFRC and high-strength reinforcement on the flexural behaviour of reinforced concrete beams. As part of the study, two UHPFRC and two high-strength concrete (HSC) beams are tested under four-point flexural loading. In addition to the effect of concrete type (UHPFRC vs. HSC), the study examines the effect of reinforcement grade (normal vs. high-strength bars) on the flexural behaviour of the HSC and UHPFRC beams. The results show that the use of UHPFRC in beams results in increased load-resistance, stiffness, and overall performance when compared to conventional high-strength concrete. The behaviour of the beams is also shown to be affected by reinforcement type, with the combined use of UHPFRC and high-strength steel leading to improvements in beam performance.
