dc.description.abstractThe prediction of the structural capacity of masonry buildings against lateral loads requires an accurate characterization of the masonry strength and the general response under shear stresses. The experimental determination of shear strength parameters typically relies on shear tests on wallettes, or on standard triplets. Aiming to avoid the behavioural interpretation problems related with the existence of two mortar joints in triplets, this paper investigates the alternative possibility of testing simple couplet specimens. A direct experimental comparison was established with tests on the two specimen configurations (triplets and couplets) performed on two different types of masonry, both characterized by low strength mortars (hydraulic lime and cement based). The obtained results include the evaluation of Mohr-Coulomb parameters, residual shear strengths, second mode fracture energy, and secant shear modulus. The findings point out that couplets yield consistent experimental results and provide systematically higher estimations of all parameters compared to triplets.
