 This paper presents a novel approach to strengthen concrete beams using recycled steel fibers. Experimental tests were conducted on notched beams and compression cubes to determine the optimal mixed design for the reinforcement material. A finite element analysis was then performed to assess the effectiveness of the strengthening technique. The results showed that the use of recycled steel fibers increased the load bearing capacity of the beams up to three times while changing the fracture mode from brittle to ductile. This strengthening technique has potential applications in civil engineering structures such as bridges, tunnels and buildings.
