Nowadays, the characterisation of Ultra-High Performance Fibre-Reinforced Concrete (UHPFRC) tensile behaviour, still remains a challenge for researchers. The aim of this project is the numerical validation of a simplified inverse analysis method to characterize the tensile properties of UHPFRC. To get this objective a Finite Element Model (FEM) is carried out in DIANA software. The parameters to characterise the concrete properties from the simplified inverse analysis method, by means of Third Point Bending Tests (TPBT), are used in the numerical modelling. The constitutive model for UHPFRC is modelled using two assumptions: a smeared cracking approach, and a discrete cracking approach.
