Shear strength of brick masonry walls assembled with different types of mortar

The prediction of masonry shear strength, by direct way, requires appropriate experimental tests on triplets, in line with standard EN 1052-3, or diagonal compression tests on panels according to ASTM 509- 2010 and RILEM LUMB6. In the present paper the results of an experimental investigation, carried out by these two types of tests on brick masonry walls assembled with different kinds of mortar are reported. A comparison between the values of the masonry shear strength, calculated applying the three formulas available in literature for the diagonal compression test data, and those obtained by laboratory tests on shear triplets, is presented.
