This paper focuses on the recent evolution of the utilization of stainless steel profiles for repair and reinforcement of historic masonry structures, which are often subjected to dynamic in-plane shear and out-of-plane loading when struck by an earthquake. The conservation of the building heritage affords many challenges to structural engineers and architects. Increase in static and dynamic load-capacity, compatibility of repair materials with historic masonry material, reversibility of reinforcement interventions, limited increase in mass, preservation of the fair-faced aspect of the masonry are examples of common issues showing the complexity of the design problem. The use of stainless steel alloys in structural engineering applications is not a new idea, but civil engineers have a limited knowledge of these alloys. This paper sets out the development of the retrofitting methods based on the use of stainless profiles and presents a review of experimental studies carried out into the mechanical behaviour of masonry structures reinforced using stainless steel. A number of cases are considered and discussed (shear reinforcement of wall panels, crack stitching, transversal connection of multi-leaf walls and retrofit of towers and chimneys) and conclusions are drawn from the reported studies.
