In this paper, a set of explicit theoretical derivations from a generalised bond-slip model for an epoxy bonded fibre reinforced polymer (FRP) sheet to concrete are presented. The derivations address the maximum bond resistance, load-slip response, effective bond length and stress-strain distributions along the FRP. The generalised bond-slip model was compared with the existing bond-slip models to obtain the optimal bond-slip parameter using bond resistance results of single and double lap shear tests results available in the literature. The theoretical predictions using the optimal bond-slip parameters showed good agreement with experimental results of double lap shear tests. Furthermore, in order to understand the influence of the bond-slip parameters, a series of parametric studies are presented. Overall, the proposed bond-slip model and explicit derivations provide complete understanding of bonded FRP on concrete, as opposed to the partial understanding provided by empirical and semi-empirical models available in the literature
