Abstract

Until now the structural reinforcement against seismic impact on buildings is mainly known by increasing the ductility of the structure to allow the building structure to move as much as possible in the plastic phase before reaching rupture, to tolerate people to evacuate the building before it collapses in the case of a serious incident. The object of this publication is to know the impact of carbon fiber reinforced polymers on the increase of the ductility of structures, and the impact of this reinforcement technique on the evolution of deformations, strain, and stress of the structure under study. A digital modeling of a building was carried out by also introducing a modeling of the fiber-reinforced polymers glued to reinforced concrete structures (columns and beams), the results of numerical modeling clearly show us the impact of fiber-reinforced polymers on increasing the ductility of the structure. The modelling enabled us to assimilate the real behavior of a building subjected to vertical forces corresponding to permanent and live loads, as well as the building’s self-weight, and thus to deduce the impact of carbon fiber-reinforced polymers on the strength of the structure.
