초록
The energy absorption capacity of ultra high performance fiber reinforced concretes (UHPFRCs) was investigated at high strain rates (45 – 92 s-1) using a strain energy frame impact machine. The UHPFRCs investigated in this study showed much higher energy absorption capacity, fracture energy, ranging 42 and 71 kJ/m2 at high strain rates than that (31 and 43 kJ/m2) at static rate. The energy absorption capacity of UHPFRC at high strain rates was strongly dependent on fiber type and fiber volume content.
