  There are currently various methods for reinforcing concrete columns, each of which can be effective depending on different conditions. One of the practical methods in this field is the use of composite materials. The composite materials have several advantages such as ease of execution, easy access, relatively low cost, and light weight. In the present study, using the laboratory results, a reinforced concrete column that has been affected by lateral reciprocating loads has been reinforced by GFRP rebar and FRP fibers. All models are subjected to cyclic reciprocating loading according to the ATC24 instruction. Then, the cover curves obtained from the analysis were double-linearized, and their coefficient of behavior and ductility ratio were calculated. In the present paper, the lateral bearing capacity, the amount of absorbed energy dissipation, the ductility ratio, the amount of hardness reduction, and the failure mode of the models have been investigated. All studied models are modeled with Abaqus2016 software. The results of this research present that the apply of GFRP rebar with FRP torsion at a location close to the plastic joint of the column increases the lateral strength by 53% compared to the conventional model and reduces the ductility. Furthermore, the use of NSM reinforcement rebars alone, increases the absorption capacity and energy dissipation in reinforced concrete columns by a maximum of 3%. However, the combination of NSM reinforcement bars along with enclosures with FRP fibers can increase the energy absorption and dissipation capacity of the reinforced concrete columns by up to 26%.
