Calculation of Plates of Variable Rigidity on Elastic Foundation with Variable Coefficient of Subgrade Reaction

In the present paper is given the calculation of plates on an elastic basis with variable and constant coefficient of subgrade reaction. The calculation of plates bending is carried out by the finite element method. The calculation results are compared for different models of plate and an elastic basis. For a two-layer plate on an elastic basis, which has a heterogeneity in the plan, the results of calculation taking into account the increase of the height of the upper structure.
