Abstract: The objective of this paper is to demonstrate the validity of a probabilistic explicit cracking model developed for current SFRCs to simulate the behaviour of an Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) beam. The parameters characterizing the tensile behaviour of the studied UHPFRC are determined from the 3-point bending tests performed on beams sawed from the reinforced UHPFRC beam. The results suggest that the probabilistic explicit cracking model is relevant to analyze the mechanical behaviour of an UHPFRC beam and provide precise information about the cracking process of this type of material. The good agreement between the experimental result and the numerical simulations permits to conclude that the studied UHPFRC behaves like current FRC, it means that it can be modelled using the same type of cracking model.
