| Popis: | The growing use of fibre reinforced concrete (FRC) on structural concrete has made that several codes and guidelines have included models for design in which the traditional reinforcement has been substituted partially or totally. Among the industrial applications, fibres as reinforcement of elevated flat slabs is gaining interest due the post-break bearing capacity of the material. This technology has already been used for real scale structures. This research contribution is focused on a parametrical analysis of FRC elevated flat slab by means of non-linear finite element simulation. The model is calibrated and compared with the real scale experimental test and with experimental slabs tested up to failure that can be found in the literature. The main goal of this paper is to carry out a parametrical analysis of the slab combining different types of reinforcement: FRC and hybrid reinforcement (fibres¿+¿conventional reinforcement) under design loads eventually choosing an amount of fibres for an actual test The results demonstrated that the combination of fibres and rebar improves the structure against failure, reduces deformation and presents a crack pattern better for cracking control.
