The uniaxial compressive response of steel-polypropylene hybrid fiber reinforced concrete (HFRC) and steel fiber-reinforced concrete (SFRC) was analyzed under high strain rate loading with a 74 mm diameter split Hopkinson pressure bar (SHPB). The experimental investigation focused on recorded data and resulted in distinguishing the strain rate that mobilized different ductility of steel-polypropylene hybrid fiber reinforced concrete (HFRC) and steel fiber-reinforced concrete (SFRC). 64 specimens of HFRC and SFRC with higher static compressive strength were tested at the strain rates changing from 20 to 120 s(-1). The static compressive strength and dynamic stress-strain curves of the two materials were obtained at 4 different strain rates and the failure stress, and peak strain and peak toughness were also analyzed. The results show that HFRC has quite good dynamic mechanical property and clear strain-rate effect, and the failure mechanism of HFRC and SFRC was also compared based on the specimens' failure modes in static and dynamic compressive tests.
