Abstract: In this research project, the impact resistance of ultra-high performance fiber-reinforced concrete (UHPFRC) panels is studied by conducting a series of impact tests using falling weights. A weight of mass 115 kg is freely dropped with an impact velocity that varies between 1.0 and 12 m/s. For reference, two types of RC panel designed to exhibit bending and shear failure modes are also tested. The effects of thickness and the addition of steel strand reinforcement and prestress on the impact resistance of the UHPFRC panels is evaluated. The failure mode of UHPFRC panels without reinforcement is found to be bending, while UHPFRC panels with added reinforcement and prestress exhibit punching shear failure. The UHPFRC panel without reinforcement has identical impact resistance to a standard RC panel of double the thickness. The UHPFRC panel with prestress has a superior impact resistance to a standard RC panel of triple the thickness.
