Abstarct: Today, the use of Fiber Reinforced Polymer (FRP) bars has received much attention due to its advantages such as high strength, light weight and corrosion resistance, but due to the linear stress-strain behavior of these materials in tension, its tensile failure is brittle, and without warning. On the other hand, since concrete is one of the materials with brittle fracture, the load-displacement behavior of concrete beams reinforced with FRP rebars lacks the necessary plasticity. Therefore, it seems necessary to provide a solution that prevents the brittle failure of concrete beams reinforced with FRP bars. In the first approach, in the tensile rebar section, an auxiliary rebar with a larger diameter and shorter length is used. At the beginning of loading, the contribution of the auxiliary rebar leads to an increase in stiffness, and then with the increase of loading, its share of the load decreases, which leads to a decrease in the slope of the load diagram. The results showed that the idea of using auxiliary bars leads to an increase in beam ductility up to 93%. In the second approach, the plasticity capacity of the compressive part has been used to increase the plasticity of the beam assembly, and in the second approach, an auxiliary shortened rebar has been used in the tensile part. For the purpose of preliminary studies to check the effectiveness of the proposed ideas, an analytical model has been presented to predict the load-displacement behavior of beams. Then, to check the results in each case, samples of concrete beams reinforced with GFRP rebars have been made and evaluated under four-point bending test. The concrete block with various confinements with CFRP sheets, Confined Concrete Block (CCB), has been investigated. Then, by placing this prefabricated enclosed block in the compressive section by creating the necessary restraint, the plasticity capacity of this block has been used to increase the plasticity of the beam assembly. In this way, with the increase of load and the distribution of multiple cracks in the enclosed block, the behavior of plasticity has been observed in the load-displacement diagram. The results of this approach have shown that the use of malleable blocks leads to an increase in beam malleability up to 133%.
