Abstract
Following the industrial evolution experienced by the modern world, the abundance of CO2 in the environment has directly induced the degradation of RC (reinforced concrete) structures due to the corrosion of the reinforcements; faced with these challenges, the confinement of RC structures with CFRP (Carbone Fiber Reinforced Polymers) becomes a minimalist solution with several advantages such as increasing resistance and ductility, as well as the ease of implementation on different types of geometry given the flexibility of CFRP and The lightness of this composite. This article will present a confrontation between the results of a test campaign carried out on cylindrical concrete specimens confined with several layer thicknesses of CFRP and then compare them with the results of numerical modeling carried out on finite element software. The numerical results obtained are close to those of the experimental ones, and the model can reproduce the ruptures and the various modes of damage observed. The models also gave a good prediction of the loading levels and the ultimate compressive strengths that caused the specimens to fail.
