Finite Element Modelling of UHPFRC Flexural-Reinforced Elements
In our research group a simplified method to obtain the constitutive tensile parameters of Ultra High Performance Fibre Reinforced Concrete (UHPFRC) from a four point bending test has been developed: 4P-IA. After the numerical validation of the method, a finite element modelling (FEM) of beams of different size has been carried out taking into account two different approaches: a smeared approach and a discrete approach. Moreover, important effects have been included in order to improve the model such as the shrinkage that generates internal stresses due to the influence of the reinforcement. After the FEM simulation, very reliable results can be observed for both approaches at service and ultimate load levels.
