Abstract:This paper presents the results of an experimental study on shear Synopsis: strength enhancement of reinforced concrete (RC) beams with adhesive bonded flexible carbon fiber sheets. A total of eight medium-sized RC beams are tested under four-point bending. Different sheet configurations and fiber alignments are used to clarify their effects on ultimate shear strength of tested beams. It is found that the externally adhesive bonded carbon fiber sheets are effective for enhancing the shear strength of RC beams. Further, it is observed that the sheets with fibers aligned parallel to beam axis are nearly as effective as that of sheets with fibers aligned perpendicular to beam axis. Moreover, the shear strengt increases with the number of sheet layers and the depth of sheets across the beam section. Maximum shear strength is obtained for the beam U-wrapped by sheets over full depth having fibers perpendicular to beam axis. An 119% increase in ultimate shear strength is achieved for this beam with single layer of fiber sheet.
