DOI: 10.1016/j.conbuildmat.2019.117748
Abstract: Abstract The efficacy of hybrid near-surface embedded/externally bonded (NSE/EB) fabric-reinforced cementitious matrix (FRCM) for flexural strengthening of reinforced concrete (RC) beams was assessed experimentally. Bending tests were conducted on eight RC beams: 6 strengthened and… read more here.

DOI: 10.1016/j.engstruct.2020.110483
Abstract: Abstract One of the major disadvantages of conventional fibre-reinforced polymer (FRP) strengthening techniques is the premature debonding of the FRP, leading to an underutilization of the materials. The externally bonded reinforcement on grooves (EBROG) method,… read more here.

DOI: 10.1016/j.jobe.2020.101422
Abstract: Abstract Flexural strengthening of reinforced concrete (RC) beams using near-surface-mounted (NSM) technique has become an attractive alternative for rehabilitation using fiber reinforced polymer (FRP) materials. Previous studies have recommended using available anchoring techniques to overcome… read more here.

DOI: 10.3390/polym14245498
Abstract: Externally bonded carbon-fiber-reinforced polymer (CFRP) technology can be used by different methods based on the anchorage device, CFRP type, and prestressing/nonprestressing. However, a direct comparison between the strengthening efficacies of different methods is still lacking.… read more here.
