Abstract
Within an experimental programme which also includes shake-table tests on three full scale prototype buildings, a set of tests on single walls has been performed for the characterisation of mechanical properties of undressed double-leaf stone masonry. These tests include vertical compression, diagonal compression and in-plane cyclic shear tests. The selected lime mortar has been specifically prepared for the experimental campaign and its strength parameters have been checked for different curing periods. Elastic properties of masonry (Young and shear moduli, Poisson ratio) as well as strength values have been derived from vertical and diagonal compression tests. Non-destructive tests have also been performed on the same masonry specimens in order to derive possible correlations with the results of destructive laboratory tests. Although an intrinsic experimental scatter of the different mechanical parameters was observed, the experimental program provided an accurate mechanical characterisation of the material. Finally, a critical comparison between the measured values and the ones suggested by different codes is presented.
