Modes of Failure

The desired failure mode is CFRP rupture after the steel yields and before concrete strain reaches 0.003 in compression. If shear/flexure crack widths are excessive, differential displacement perpendicular to the CFRP at the crack will cause a shear failure of the laminate or the laminate will peel away from the concrete surface. This is another reason for restricting the stress/strain of the carbon laminate. At stresses less than 50 percent of ultimate strength, flexural cracks can be spanned and flexural performance is not restricted. The most undesirable failure is delamination or failure of the adhesive between concrete and laminate. The latter was avoided by ensuring the concrete surface was sound and that precautions were taken to remove loose material and laitance. Concrete tensile strength is less than the adhesive. Thus, failure can occur in the concrete as a secondary fracture with a thin layer of concrete adhered to the laminate or adhesive.
