EnglishThe objective of this current research was to investigate effective and practical approaches for strengthening calcareous block walls with openings to resist the hazard of the in-plane shear loads. Afer a previous experimental analisys aimed to determine the mechanical propiertes of the employed materials developed by the same authors, a numerical investigation by F.E.M. capable of cacthing even the most complex phenomena both in the behavior and the failure mode of the masonry-FRP system, was carried out. In order to obtain a real effectiveness of the composite system, different distributions of the CFRP were considered. The most effective distribution of the composite system in terms of resistance, ductility and economy was that of grid and it was adopted to perform the laboratory samples. Four masonry panels with openings scaled 1:2 in size were constructed and tested. The specimens were tested under static and cyclic loads. It was found that both the strength and ductility of tested specimens were significantly enhanced with the proposed strengthening technique.
