This study examines the impact energy dissipation capacity of Ultra High Performance Fibre Reinforced Concrete (UHPFRC). For this purpose, nine different mixes were fabricated with hooked end and crimped steel fibres at a dosage of 0.5, 1.0, 1.5 and 2.0 percentage and tested under pendulum impact test. The impact energy dissipation capacity is assessed based on test (Charpy U-notch) procedure suggested by ASTM E23. Also, an analytical model was adopted to predict the impact energy dissipation value of UHPFRC and its performance is verified against experimental results. Based on the test results, the impact energy dissipation capacity of the mixtures containing crimped and hooked end steel fibres were significantly higher than that of Plain Concrete (PC). The hooked end steel fibres had an increased impact energy dissipation capacity compared to crimped steel fibres, which implies that hooked end steel fibre is more appropriate for enhancing the impact energy dissipation of UHPFRC. Also, the modelling data compared well with experimental data for the fibre volume fraction beyond 0.5%.
