The paper deals with the application of unidirectional fiber reinforced plastics (FRP) for strengthening of masonry monuments. The materials are applied in the form of either externally applied circumferential tendons to provide horizontal confinement, or laminates, which are epoxy-bonded to the facades of masonry buildings serving the role of tensile reinforcement. Post-tensioned FRP ties may increase the strength of unreinforced masonry under horizontal (shear-type) and/or vertical loads considerably. Externally epoxy-bonded laminates, on the other hand, appear to give both efficient and effective solutions if aesthetics or other considerations call for a strengthening scheme of low weight.
