Abstract
The determination of mobility of the concrete foundation on a natural subgrade is rather relevant for the strength analysis of multistory brick buildings with a spatial cross-wall structural system. During the inelastic soil behavior, its ultimate limit and elastoplastic states are allowable along the concrete foundation perimeter, the bearing capacity of the foundation being provided as a whole. In this case, it is important to adhere to the standard conditions of the foundation deformation and mobility. The finite element modeling of the stress-strain state of the concrete foundation and the building superstructure of the base-foundation-building system is performed in the MicroFe software package. A consideration of inelastic soil deformations in the natural subgrade results in unacceptable displacements of the concrete foundation.
