Numerical simulation of masonry walls strengthened with vegetal fabric reinforced cementitious matrix (FRCM) composites and subjected to cyclic loads

The growing concern for the preservation of old buildings and the wide use of masonry in the construction of civil works has led to a great development of specific techniques to strengthen masonry structures. FRCM (fabric reinforced cementitious matrix) of vegetal fibres arises as a strengthening op...
