Abstract
Fifteen (15) reinforced concrete beams, were tested to assess the hybrid mechanically fastened-externally bonded fiber reinforced polymer (MF/EB FRP) strengthening technique to enhance the shear capacity of reinforced concrete beams. The results of this research work can be added to those few existing in the literature on the use of mechanically fastened fiber-reinforced polymer strengthening system. This research aims to investigate the shear contribution of MF/EB FRP to the shear resistance of RC beams. It was possible through this research to study the effect of using diagonal MF/EB strips versus that of using the vertical strips. The failure mode of the externally bonded system was mostly categorized as premature debonding that is associated with shear failure. As for the MF/EB specimens, the failure mode was categorized as flexural failure associated with detachment within the concrete. This indicated the superior behavior of this system that eliminated the shear failure of the strengthened beams.
