Shear Bond Strength of Rehabilitated Steel Plate Bonding CFRP Plates Part 2 Failureconditions of adhesive

摘要

To enhance the usable life of existing building, a strengthening method with bonding CFRP Plates has been developed by authors. The CFRP Plates is high-strength (2100MPa) in longitudinal normal stress. The composite member of steel bonding CFRP Plates has enough bending strength when no bending moment works at the edge of CFRP Plates. The composite of steel bonding CFRP may easily peel out under tensile loading because shear bonding stress is concentrated at the edge of CFRP Plates. In this paper, Tensile Loading Tests of composite of steel bonding CFRP Plates were performed to clarify the validity of the proposed formula.
