	abstract = {<p>Externally bonded reinforced systems have been widely used in civil engineering. However, the problems associated with bond between structural elements are not yet fully solved. As a consequence, many researchers have been proposing tests and techniques to standardize procedures and reach better agreement for design purposes. In the present paper, an experimental program is described that was developed to characterize the glass FRP/concrete interface by double shear tests made on 15\&$\#$xa0;cm side cubes with GFRP bonded on two opposite faces. The GFRP wrap had two layers applied by the wet lay-up technique and three classes of concrete were considered. With the support of the experimental program, cohesion and friction angle for GFRP{\textendash}concrete interfaces were found leading to different envelope failure laws, based on the Mohr{\textendash}Coulomb failure criterion for each concrete class, capable of predicting GFRP debonding. Results are discussed.</p>
