Abstract: An experimental investigation has been conducted to address the advantage of using UHPFRC for impact resistance applications. Five identical reinforced concrete (RC) plates, with exception of concrete materials, are tested under repeated impacts by dropping a 475 kg steel weight from a height of 4.15 m. Two reference specimens are constructed using plain normal- (NSC) and high-strength concrete (HSC) mixes, while the other three are constructed using UHPFRC with varying steel fibre volume contents of 1, 2, and 3%. Impact resistance characteristics have been evaluated based on visual inspection, and imparted energy. Test results show that UHPFRC exhibit superior impact resistance characteristics in comparison to traditional concrete. The use of a fibre content of 3% is more effective in enhancing the dynamic performance and damage control properties of UHPFRC structural members. The total impact energy of UHPFRC plate containing 3% fibres was found to be double the capacity of UHPFRC plate containing 2% fibres and 18 times the capacity of NSC plate.
