This paper consists on the numerical simulation based-finite element modeling carried out on
reinforced concrete (RC) beams predamaged and strengthened with carbon fiber sheet (CFRP) and a fiberglass
(GFRP) jacket under monotonic bending loads. The retrofitted RC beams were modeled using ABAQUS to
estimate the effect of concrete and steel damage rate. After the experimental validation of the proposed model,
four configurations of damage rate were considered according the initial compression resistance of undamaged
concrete. Indeed, the geometrical model and the choice of the finite element models were generated in a full
three-dimensional (3D) space. Moreover, the real behavior of each used material has been simulated using the
experimental laws of each one, namely: concrete damaged plasticity, elastoplastic steel model with isotropic
hardening and orthotropic elastic one for FRP composites. The discussion of the numerical outcomes in terms of
bearing capacity curves and the tensile damages maps provides the full interest of the FRP repair technology on
the overall and local flexural response of predamaged RC beams.
