Abstract: This paper investigates the impact of reinforcement ratio on the deformation capacity of High-Performance Fiber-Reinforced Cementitious Composites (HPFRCCs) reinforced with mild steel. Prior experimental research has shown that HPFRCCs effectively restrain splitting cracks, causing a tension-stiffening effect that results in reinforcement fracture at lower levels of deformation than in normal reinforced concrete. Results from prior studies on reinforced HPFRCC components are summarized in this paper and show that the deformation capacity of reinforced HPFRCCs increases with reinforcement ratio. New experiments, motivated by these prior studies, on reinforced HPFRCC beams under monotonic and cyclic loads in three point bending are presented demonstrating a difference between monotonic and cyclic deformation capacity. Experimental data is combined with previous research to address important considerations on how reinforced HPFRCC structural elements should be designed.
