Abstract

The article deals with the foundations of buildings and structures in the form of shallow shells on an elastic foundation. The derivation of equations is given taking into account the geometric nonlinearity of the work of a thin-walled structure. The technique for solving systems of equations using the Bubnov-Galyorkin method is given. The work of the structure with various ways of fixing the edges is simulated. The elastic foundation is represented as a set of layers with different strength and deformation characteristics that change along the bottom of the foundation. The influence of the characteristics of the elastic foundation, the shape and thickness of the foundation structure on the value of stresses and critical load is investigated. The results of the above studies are given in a dimensionless form and illustrated by graphs, which makes it convenient to use them in engineering calculations. Recommendations are given for adjusting the shape and thickness of the foundation structure in the form of shallow shells to increase their bearing capacity or reduce consumption of materials.
