Abstract: The article is devoted to the study of the stress-strain state of the elements of the frame of a multi-storey building when correcting the tilt with the use of various types of adjustable foundations. Finite-element models of a multi-storey building with structural measures of protection against the influence of excess tilts, which take into account the interaction of the structure with the deformable base and the construction of foundations with dimensions that change during the calculation, are developed. Technological schemes of building alignment are justified. At the same time, the schemes of lowering the less sagging parts of the building with the use of a regulating device of the «sandbox» type and lifting the more sagging parts of the building with the help of adjustable jacks were considered. A comparative analysis of the obtained results of the stress-strain state of building structures using various types of adjustable foundations is presented.
Keywords: nonuniform deformation of the base, stress-strain state, tilt, correction of the tilt of the building, sandbox, adjustable jack.
