Annotation: In this article, the limiting conditions of the walls and the window sill of the wall were studied with changes in the pressure on the base as a result of the redistribution of loads on the base from special influences, for example, curvature of the earth’s surface during the undermining of the territory. For calculations, the research software package was used «PANAMA». The problem is solved in the framework of the theory of the plastic flow of masonry. The equations of the Coulomb Mohr theory of strength are used, in accordance with which the strength of the material depends on the level of volumetric tensile–compression stresses. The calculation results are evaluated by the level of stress and strain state of structures. The level of stress state refers to the ratio of stress intensity to the strength of materials. The value of the voltage level equal to unity indicates the flow of the material of the structure. The level of the deformed state is understood as the ratio of the strain intensity to the ultimate compressibility or elongation of the material. Ultimately, the state of the structure is estimated by the level of the deformed state. The value of the level of the deformed state of equal unity corresponds to the achievement of ultimate compressibility or elongation of the material. In this work, the limiting state of the structure is estimated by achieving the maximum compressibility of the masonry.

Keywords: stress-strain mill, ductile stretch, «PANAMA».
