Limit Values of Shear Strength for Masonry Made of Porous Ceramic Blocks

Abstract
The article presents the results of experimental studies of shear strength in the plane of horizontal mortar joints of masonry from porous ceramic blocks. The initial shear strength values were investigated (strength of tangential adhesion), as well as the ultimate shear strength values. Experiments with masonry were carried out in accordance with STB EN 1052-3 with simultaneous action of compressive and shear forces. Depending on the compression level, the destruction of masonry occurred due to a shift along the border of the masonry product and the mortar joint and fragmentation of the partitions between the voids of the blocks. It has been established that the limiting values of masonry shear strength, given in the standards for the design of stone structures, significantly exceed the experimental values. The need to correct the provisions of regulatory documents regarding the ultimate values of shear strength of masonry from porous ceramic blocks is indicated.
