Experimental and numerical insights on the diagonal compression test for the shear characterisation of masonry

The masonry tensile strength and shear modulus play a key role in the definition of capacity structures. These properties are often determined experimentally by means diagonal compression test on square walls, which is regulated ASTM E519 standard. In spite its wide use, interpretation still controversial no universal criterion exists how to derive mechanical from wall overall strength. Aiming contribute improvement test’s reliability interpretation, this paper presents an investigation use characterise masonry. First, experimental campaign brickwork walls described. were built laboratory Flemish bond, pattern that has been scarcely investigated available research studies type test. Second, advanced numerical model used for analysis subjected adopted model, enhanced crack-tracking algorithm reproduce accurately damage localization, constitutes very useful powerful tool interpret correctly behaviour during Finite element was executed walls’ response linear nonlinear ranges with models properly calibrated comparison results. As result, calculation outcomes A sensitivity carried out regard most influent material material, geometrical dimensions panel, loading conditions testing setup. findings finally applied validated simulations tests eight campaigns performed other authors different typologies.
