Abstract
This paper presents the comparative fire performance of reinforced concrete (RC) beams made of concretes with different strengths by undertaking fire resistance tests. Four RC beams made of normal strength concrete (NSC), high strength concrete (HSC), and ultra-high performance concrete (UHPC) with different fiber combinations, were subjected to structural loading and tested under fire conditions. Results from the fire resistance tests show that UHPC beams undergo severe fire-induced spalling and exhibit lower fire resistance as compared to HSC and NSC beams. Additionally, the inclusion of polypropylene (PP) fibers in UHPC beams aids in reducing spalling and increasing fire resistance in UHPC beams.
