The task of obtaining deformation diagrams of stone masonry of compressed structures on the basis of the theory of resistance of anisotropic materials to compression is set. The principal difference between this theory and existing approaches to assessing the strength and crack resistance of compressed structures and elements is the consideration of the values of the material’s resistance to tension and shear when determining the compressive strength. For this, the basic calculation expression was written using the deformation characteristics that made it possible in combination with the analysis of a set of experimental data on testing of prototypes to describe analytically the stages of the stress state and obtain the algorithm for diagrams of deformation of the compressed stone masonry material in the typical intense areas: «σ–ε», «σt–εt» and «τ–γ». This method of assessment of the stress-strain state of the masonry material of compressed structures and elements is fundamentally new in relation to the existing and can be proposed for implementation in the design standards.
