This study investigates the dynamic impact mechanical properties of Ultra-HighPerformance Concrete (UHPC) with high-content and directional reinforced steel fiber. The research
explores the influence of directional distributed steel fiber on the dynamic impact properties of UHPC
specimens prepared with varying fiber contents. Through experimental analysis using the splitHopkinson pressure bar (SHPB) method, stress-strain curves, stress peaks, dynamic increase factor
(DIF), and ductile energy absorption properties of the specimens at different strain rates were
obtained. The results demonstrate that oriented steel fiber significantly enhances the dynamic
properties of UHPC, with notable improvements in peak strain, peak stress, and energy absorption
capacity. The study reveals that increasing fiber content leads to enhanced peak stress, energy
absorption, and multiple-impact compression resistance of the specimens. Overall, the findings
highlight the effectiveness of directional reinforced steel fiber in improving the dynamic impact
performance of UHPC.
