Abstract: The surface characteristics of dry stack block masonry, built with interlocking blocks, control the overall performance of a structure. In this research work, the shear parameters of dry stack block masonry (DSBM) have been evaluated experimentally by testing DSBM walls through diagonal tension testing protocols. The DSBM walls were tested under the diagonal compression loading with and without edge load. The results have been evaluated by using available research models. Coefficient of friction, cohesion, diagonal tensile strength, shear strength, and shear modulus have been found from the experimental tests. This study shows that the shear parameters of DSBM are greatly influenced by axial compression. In the presence of axial compression load, the values of shear parameters of DSBM are closely matched with the values of regular mortared masonries.
