Abstract:Fiber reinforced polymer (FRP) composites in the form of laminates or bars have been proven to be effective for the strengthening of unreinforced masonry (URM) walls subjected to overstresses. Two installation techniques have been proposed: externally-bonded FRP laminates (i.e. manual lay-up or adhesion of pre-cured laminates) and near surface mounted (NSM) FRP bars. The latter technique consists of placing a bar in a groove cut into the surface of the member being strengthened. This paper presents a field application on flexural strengthening with NSM FRP bars of two cracked URM walls in an educational facility. Design considerations and the results of an experimental program conducted to validate the strengthening are described.
