The application of steel-reinforced polymer (SRP) composites in structural strengthening is a new concept based on the use of highstrength steel cord. This paper presents the results of an experimental program on the flexural behavior of reinforced concrete (RC) beams strengthened with SRP, including the performance of epoxy resin versus cementitious grout to impregnate and bond SRP to concrete, as well as the feasibility of nailing the SRP to prevent peeling. The use of cementitious grout is highly relevant as it could overcome the issue of fire resistance and further reduce the cost of the strengthening system. Test results were compared to those from beams strengthened with carbon fiber-reinforced polymer (CFRP) under the same experimental program. This preliminary work shows the high potential of SRP strengthening systems and identifies some critical issues that should be investigated next in order to optimize the effectiveness of the proposed strengthening solution.
