Abstract

Recently, the near-surface-mounted (NSM) technique has become an attractive alternative to the externally bonded (EB) technique. Compared to the EB technique, the NSM technique is less exposed to external damage sources and provides a stronger bond between the FRP reinforcement and the surrounding concrete. A numerical investigation utilizing the non-linear finite element modeling (FEM) was performed using ANSYS®software to validate experimental results. Analytical models were conducted to simulate the flexural behavior of Reinforced Concrete (RC) beams strengthened with NSM FRP bars considering the FRP Cross-sectional area, end-anchoring of the CFRP bar, and strengthening by partially bonded systems with different unbonded lengths. It was found that the modeling approach could simulate the experimentally measured beams behavior at all stages of loading with an acceptable degree of accuracy.
