N2 - The embedded through-section (ETS) technique was recently developed to avoid the debonding failure that occurs with other FRP strengthening techniques such as the externally bonded (EB) and near-surface-mounted (NSM) methods. The method offers greater confinement and leads therefore to a substantial improvement in bond performance. In this study, experimental results from 13 direct-shear test specimens are reported. The influence of the following major parameters on the bond behavior of FRP-strengthened reinforced concrete beams is examined: concrete strength, hole diameter, bar diameter, bar surface area, and bar bond length. The experimental results show that debonding can be avoided by providing a sufficient bar length and high concrete strength. As a result, designers will be able to avoid debonding failure and to develop the full capacity of shear-strengthened beams.
