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 option to be considered because low cost, low density, recyclability and biodegradability brought by vegetal fibres. In this study, numerical models were used to represent masonry walls unreinforced and strengthened with FRCM (hemp, cotton and glass). The numerical model presents a new way of simulation of FRCM systems and their failure pattern. This was validated by comparison to previous experimental and analytical results. Results showed that proposed model is an effective calculation tools to reproduce the maximum shear of masonry walls strengthened with FRCM and subjected to cyclic loads, with variations between 7 and 15% with respect to the experimental and analytical. The numerical model was also useful to reproduce the walls hysteresis behavior, although showed some inability to reproduce the reversible crack opening-closing that was observed in the experimental tests.
