Résumé
The shear strengthening technique investigated in this paper consists of inserting steel reinforcing bars into holes drilled into a shear-deficient existing concrete member and bonding these bars to the concrete with high-strength epoxy adhesive. It is important to realize that current shear design methods are applicable to RC members with conventional stirrups and hence overestimate the shear capacity of members with epoxy-bonded bars. In order to overcome this difficulty, a shear design method for RC members strengthened with epoxy-bonded shear reinforcement is presented. The proposed method was developed considering the development of epoxy-bonded bars as well as the effect of crack width and aggregate interlock on shear capacity. The predicted shear capacities were compared with beam test results and provide accurate predictions.
