Thepaperpresentsapreliminarylocalinvestigationrelatedtoslidingonamortarjointdue to excessive shear force, mechanism observed during testing of masonry arches and barrel vaults re- inforced with Externally Bonded Fibre Reinforced Polymers (EB FRP) at their extrados. This activity was aimed at evaluating a possible contribution of the FRP reinforcement to joint resistance. Four- teen V-shape Peel Tests (VPT) have been performed, which consist in peeling off a central FRP strip from two clay solid bricks aligned along their longitudinal axis, so that the reinforcement assumes a typical “V” shape during detachment. Tests were designed to reproduce and isolate the reinforce- ment mixed-mode debonding behaviour related to the above mentioned failure mechanism, and their execution allowed assessing experimental setup and procedures.
