Abstract: The use of NSM FRP strengthening of concrete structures has become an attractive option to retrofit the existing structures against shear and flexure. This paper reviews only the utilization of NSM for shear in previous review articles. A database of tests of NSM strengthened beams in shear is presented to evaluate the existing design formulations of calculating the NSM contribution in shear. These formulations were in agreement with the experimental results in the database. Further research topics are also id… Show more

Reinforced concrete (RC) beams strengthened in flexure using externally bonded (EB) or near-surface mounted (NSM) fiber-Reinforced Polymers (FRP) and metals have gained considerable interest over the last few decades. As few of the previous review papers concerned with NSM elements or both EB and NSM methods so this paper aimed to review the previous research that handled the behavior of RC beams strengthened by NSM and EB techniques, compared their advantages and disadvantages and reported the future recommendations. Moreover, the review focused on the effect of strengthening materials (metallic and FRP materials), strengthening method, strengthening elements characteristics (shape and area), and any other factors affecting the performance of the strengthened RC beams in each technique. The review demonstrated that the strengthening element’s failure mode significantly affects the RC beams’ load-carrying capacity strengthened by EB or NSM. Moreover, the type of FRP materials and the end anchorage significantly affect the load efficiency of the strengthened RC beams depending on the type of failure mode.

With the development of recycled aggregate concrete (RAC), the recovery rate of construction waste is improved, and the pollution problem is alleviated. In particular, RAC beams strengthened with prestressed carbon fiber reinforced plastics (CFRP) can exhibit improved mechanical properties, expanding RAC application. Four groups of reinforced RAC beam specimens contained 0%, 40%, 70%, and 100% recycled coarse aggregate, respectively. Each group of beams was first pre-cracked and then strengthened by prestressed CFRP with one layer and two layers respectively. Finally, the bearing capacity tests were performed for these beams. The test results show that as the recycled coarse aggregate content increases, the cracking moment and ultimate load capacity of the beam decrease, while its crack width increases. As the CFRP layer increases, the deformation and crack width of the beam decreases, while the number of cracks increases. The prestressed CFRP also exhibited tensile and peeling failure. A beam deflection calculation model was established by introducing a coefficient k representing the interaction between recycled aggregate and CFRP. The influence coefficient of concrete elongation on the crack width and average crack spacing of the beam was modified, and the crack width analysis model of the beam was established. The calculated results are in good agreement with the experimental observations. It can provide reference for the application and design of recycled concrete beams strengthened with prestressed CFRP.
