Abstract

Fiber Reinforced Plastic (FRP) can be used for strengthening concrete or masonry constructions.
One of the main problem in the use of FRP is the possible detachment of the reinforcement from the support
material. This paper deals with the modeling of the FRP-concrete or masonry damage interface, accounting for
the coupling occurring between the degradation of the cohesive material and the FRP detachment. To this end,
a damage model is considered for the quasi-brittle material. In order to prevent strain localization and strong
mesh sensitivity of the solution, an integral-type of nonlocal model based on the weighted spatial averaging of a
strain-like quantity is developed. Regarding the interface, the damage is governed by the relative displacement
occurring at bond. A suitable interface model which accounts for the mode I, mode II and mixed mode of
damage is developed. The coupling between the body damage and the interface damage is performed
computing the body damage on the bond surface. Numerical examples are presented.
