THE FEATURES OF THE DEFORMATION BEHAVIOR OF REINFORCED MASONRY STRUCTURES UNDER TECHNOGENIC IMPACT IN SUBSIDED AREAS

This paper considers the mechanism of the transfer of mining-caused deformations from subsided soil mass to the structural components of reinforced masonry structures (brick buildings). Different models of the behavior of a brick wall and a ground base, as well as variants of their contact interaction, are considered. The limiting strains of the ground are determined for the characteristics specified in the models. The level of strains and their growth in the bearing elements of reinforced masonry structures is shown to be essentially governed by the choice of the type of interaction of the structural elements in the system with the ground base. Curves showing the averaged strain in a brick wall of bonded section for different strength grades as a function of the deformation of the ground base are plotted on the basis of the models.
