Abstract


  • This paper presents a bond-slip model for interfaces between near-surface mounted (NSM) CFRP strips and concrete where debonding occurs due to cohesion failure in the concrete adjacent to the CFRP strip. This bond-slip model was derived on the basis of numerical results from a parametric study conducted using a verified 3-D meso-scale finite element (FE) model. In the proposed bond-slip model, the concrete compressive strength and the groove height-to-width ratio are the two main parameters: the former indicates how strong the concrete itself is while the latter represents the level of confinement provided by the surrounding concrete to the bonded interface. The proposed bond-slip model provides an essential building block for an FE model for predicting debonding failures of RC structures strengthened with NSM CFRP strips.
