Due to the fact that many of the existing structures have been in existence for over a decade, retrofitting has become one of the greatest challenges facing structural engineers. There are several methods to retrofit that, due to the unique properties of FRP composites, their use for the repair of reinforced concrete members has become one of the most commonly used methods. One of the most important factors in the need to retrofit the shear wall is the insufficiency of the shear bending of the beam in the shear wall of the cooper. Considering the fact that the price of FRP materials is one of the limiting factors for its use in improving structures, in this study, Numerical and Laboratory Results With the help of ABAQUS Limited Components Software, 5 different FRP derivatives that reduce the use of FRP in the seismic reconstruction of the coupler shear wall fittings were introduced. The results obtained from these 5 samples were compared with the base model without FRP coating and the sample, which has a complete overlapping of FRP, and the sample, which is multiplied by drowning, was selected as the best sample, which reduces the cost of refinement The connective beam is in the wall of the shear joint.
