The article describes the well-known design of a tape-shell foundation. Based on the analysis of the known design, a number of factors affecting the limitation of the scope of the tape-shell foundation are derived. In order to ensure the controlled inclusion of the reinforced concrete shell of the foundation in the work, the author of the article proposed the use of a damping gasket under the tape support contours. A gasket made of an easily compressible slab material - polystyrene foam - is compressed under the influence of the load from the walls and columns of the basement of the building, the reinforcement of the shell is stretched and involves the soil of the subshell part of the foundation. At the same time, the strength characteristics of the band-shell foundation increase, the sediment decreases. The author of the article conducted numerical studies to determine the required thickness of the gasket. It is proved that the use of a damping gasket is relevant for soils with a deformation modulus of less than 15 MPa, above this value, the use of a gasket is impractical.
