Abstract

ABSTRACT: This study aims to evaluate the structural behavior of reinforced concrete beams, reinforced with carbon fiber fabric, using an anchoring mechanism composed of carbon fiber strand inserted in concrete. Five beams were used in order to evaluate the mechanism applied in shear reinforcements. All beams were applied to the transverse loadings and instrumented to measure the breaking load, vertical displacement, deformation specifically in steel, concrete and reinforcement and failure mode. The results concluded that the studied anchoring mechanism acts to prevent the structural element from premature destruction through detachment or loosening of the reinforcement. The main improvements were made in the ductility of the beams and increase in their load capacity, which made an increase of more than 300% over unreinforced beams. Through this result, it was concluded that the mooring system by insertion of carbon fiber strand was efficient for both types of reinforcement.
