This work presents the numerical simulation of four-point bending tests on hybrid beams composed of polipropylene fiber reinforced foamed cellular concrete combined with normal concrete in the upper layer and traditional steel reinforcement. The simulation methodology was developed by the research group and has been previously published and validated through comparison with experimental tests conducted on beams with identical configurations. The simulations were implemented using a nonlinear finite element code that considers the coupling between damage and plasticity. Based on the validated computational model, a parametric study was conducted in which the diameters of the lower longitudinal reinforcement bars were varied.
