Abstract
This paper presents an accurate bond strength model for carbon-fibre-reinforced polymer (CFRP) strips near-surface mounted (NSM) to concrete where debonding failure happens in the concrete layer adjacent to the interface between FRP and concrete. Both bonded joints with a sufficient bond length and those with an insufficient bond length are covered by the proposed model. The bond strength model was developed on the basis of an existing analytical solution as well as a recently proposed bond-slip model for such bonded joints. Numerical comparisons between the proposed bond strength model and 51 test specimens collected from the existing experimental studies as well as the only existing bond strength model for such joints demonstrate the accuracy of the proposed model and its superiority over the existing bond strength model, especially for joints with insufficient bond lengths.
