In a recent experimental program, the performance of a novel shear strengthening technique, designated by Embedded Through-Section (ETS), was appraised by performing a series of beam bending tests composed of eight reinforced concrete (RC) beams. According to this strengthening technique, holes are opened through the beam???s section, with the desired inclinations, and bars are introduced into these holes and bonded to the concrete substrate with adhesive materials. The strengthening elements are composed of steel bars bonded to the surrounding concrete with an epoxy adhesive. Based on the obtained results, a significant increase in terms of ultimate load and deflection was registered, and the brittle shear failure more observed in the reference beams was converted in a flexural ductile failure more observed in the strengthened beams. To have a better assessment of the contribution of the ETS bars for the shear resistance of RC beams, material nonlinear analysis were performed with a FEM-based computer program. Finally, the applicability of the ACI 440 and 318 standard specifications for shear resistance were examined. A good agreement between the experimental, numerical and analytical values was obtained.
