“…As an example, we have considered the masonry fragment from a full-bodied brick of M100 grade and a mortar of grade M75 under uniaxial compression. The substructural materials are brick, mortar of the horizontal and vertical joints, mortar is in the contact zone between brick and horizontal joint [13]. The size of the fragment is 1030×1050×250 mm, it is shown in Fig.…”

The strength and stiffness of masonry depend on various factors, such as the properties of the brick and mortar, their specific volume, relative position and quality of adhesive bonds. A high degree of uncertainty of these factors and a large scatter of experimental data in the testing of bricks and mortar are the important features of the masonry. In this paper, we present a mathematical model that allows us to determine the averaged characteristics of masonry based on the mechanical properties of substructural materials and their specific volume content in a fuzzy setting. All input parameters allowing to obtain fuzzy estimates of stresses and deformations of a brickwork fragment are determined by membership functions. For a representative volume of masonry, dependencies are obtained that allow to determine the level of destructive loads and the nature of destruction.
