%X Shift stability assessment of concrete structures is the main task in the design. In addition to the linearly sliding shift in the plane of the structure foot there is often a danger of loss of stability of the construction according to the rotational shift. To assess the stability of the construction according to this scheme a design procedure was developed, using a limit equilibrium procedure. The proposed methodology is based on the exact analytical formula for the elements of the flat foot of structure of rectangular and triangular forms and subsequent synthesis of these solutions for the construction with foot of any form.For structures with an arbitrary foot shape the linear distribution of normal stresses on the plane of the foot is used. In the study we used the solution, based on nonlinear law of distribution of normal stresses used for structures with the rectangular foot.
