SHEAR STRENGTHENING OF RC BEAMS USING CARBON FIBER REINFORCED POLYMER STRIPS
Abstract eng: Five RC beams without shear reinforcement were cast at the concrete laboratory of New Jersey Institute of Technology. After the beams were kept in the curing room for 28 days, Carbon fiber strips and fabrics made by SIKA Corp. were applied on both sides of the beams at various orientations with respect to the axis of the beam. All beams were tested on a 220-kip MTS testing machine. Results of test demonstrate the feasibility of using externally applied, epoxy-bonded CFRP system to restore or increase the shear capacity of RC beams. The CFRP system can significantly increase the serviceability, ductility, and ultimate shear strength of a concrete beam, thus restoring beam shear strength using CFRP is a highly effective technique. An analysis and design method for shear strengthening of externally bonded CFRP has been proposed as well.
