Masonry is often a non-engineered material used for building constructions during the past decades; those kind of structures have been rarely designed against horizontal actions induced by earthquakes and usually have been simply realized according to rules of common practice. Consequently, they are often in need for strengthening in order to fit the safety standards assumed by the modern codes. Strengthening interventions on ordinary structures can be particularly addressed to improve in-plane shear strength of masonry walls that are, on the contrary, rather fit to sustain axial loads. Ferrocement-based techniques have been often utilized though resulting in non-negligible increase of structural masses and quite irreversible interventi...
