PROCEDURE FOR CALCULATING THE PLATE ON AN ELASTIC BASE WITH A LOT OF REDUCED BASE RIGIDITY
An approximate method is proposed for calculating the bending of a slab on a Winkler base with a local area in it with a lower bedding ratio than at the base under the rest of the slab. The method is based on the regularity that the sought deflections of a slab having such a local section at the base will always be in the range between the corresponding deflections of the slab located: in the first case - on the base in which there is no such section, and in the second case - on the base, in which there is such a site, but there is no contact between the slab and the base. In both cases, the deflections of the slab are established according to known analytical solutions, and the location of the sought deflection between them is established using the so-called relative coefficient of reduction of the stiffness of the base.
