This work describes the research developed to evaluate the bond shearstrength of prisms of structural masonry. The main appraised requirements were the compression strength of the mortar, the bond shear strength of the mortar joint, the definition of a test specimen thatsupply better results for the evaluation of this parameter and the failure mode of the prisms. The methods for testing used to analyze the bond shear strength were: direct shear tests, diagonal compression tests and tests with precompression. The results showed that the bond shear strength obtained from the compression diagonal tests are more reliable in relation to the strengths obtained in the direct shear and precompression tests, due to the smallest variation coefficients and to the failure mode of the prisms, whose characteristics are similar to the failure that happen in walls requested by lateral stresses.
