quote
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.
