I have conducted two types of shear tests on unreinforced clay-brick masonry specimens:
The diagonal tension test is also considered as a testing method to evaluate the shear strength of masonry (a pure shear stress state is assumed: the shear strength = 0,707*P/A).
Is there a theoretical relationship between the results of a triplet shear test (which results in values for the Coulomb' criterion) and the shear strength obtained by the Diagonal Tension test (ASTM E519 - 07)?
The shear strength (shear stress), cohesion and angle of friction can be calculated from Shear triplet test. Moreover, from recent investigation - Diagonal Tension test isn't necessary to calculate the shear strength of the Masonry. However, diagonal tensile strength can be calculated from Diagonal Tension test.
Thanks!
