“…However, in some relatively recent research studies, the effectiveness of TRM systems for retrofitting clay brick masonry walls has also been investigated by performing induced diagonal shear testing of retrofitted masonry assemblages (Faella et al, 2010;Mantegazza et al, 2006;Papanicolaou et al, 2007Papanicolaou et al, , 2011. Parisi et al (2010) performed quasi-static testing of a single URM wall with openings.…”

The in-plane shear behaviour of unreinforced masonry wallettes retrofitted using polymer textile reinforced mortar was investigated. In particular, the effectiveness of the retrofit technique to restrain the diagonal cracking failure mode was studied. A total of 12 two-leaf thick clay brick masonry wallettes, each being 1·2 m square in size, were structurally tested in induced diagonal shear. Of these, two wallettes were tested as-built and ten were tested after being retrofitted using different commercially available textile reinforced mortar systems. Several parameters pertaining to the in-plane shear behaviour of retrofitted masonry walls were investigated, including failure modes, stress–strain behaviour, shear strength, maximum drift, pseudo-ductility and shear modulus. It was inferred from the results that the observed diagonal shear strength increase for test wallettes having textile reinforced mortar on one face ranged between 114% and 148%, whereas the test wallettes having textile reinforced mortar on both faces failed in a brittle manner, exhibiting a shear strength of between 446 and 481% of their as-built strength.iffness and energy dissipation capacity of the frame increased significantly.

In addition toFibre-Reinfocedcomposite materials, which are made of long glass/carbon/aramid fibers embedded in a polymer matrix (FRP), the use ofFRCMcomposites (Fabric-Reinforced Cementitious Matrix) is becoming more and more widespread. As far as this specific case, the inorganic matrix guarantees many advantages, especially when dealing with masonry substrates, including a good compatibility from both a physical and a chemical point of view and the possibility of wet lay-up application. Despite their wide use in technical applications, the constitutive behavior and the failure mechanisms of FRCMs have not been adequately studied. As a consequence, a final assessment upon which criteria have to be used for verification and qualification ofFRCMsis still missing. In the context of a recent experimental program-still under development-cooperated by many Italian academic laboratories, that is aimed at detecting the main features of the constitutive behavior of these materials, a discussion seems to be appropriate on the initial experimental results obtained at Salerno University on manyFRCMspecimens tested under uniaxial tensile loads.
