An in situ experimental testing campaign on stone masonry walls performed in the Volterra (Pisa, Italy) hospital complex is described herein. The test-site is a disused building, dated back to the early 1930s, which offered the opportunity to perform destructive and non-destructive tests with multiple purposes: the masonry mechanical characterization of a wide group of nearby similar buildings, the comparison of several testing methods applied on masonry with chaotic texture and the development of the innovative twin panel test procedure. In this context, the failure mode for panels under shear and compression forces was interpreted and, through the results obtained from different techniques (flat-jack test, drilling test, diagonal compression test and shear compression test), a safety domain shear vs. compression for the rubble masonry type was also drawn up. The cross validation of several testing methods can suggest strategies to determine shear strength, deformation properties and ductility capacity of stone masonry walls with highly irregular texture.
