CONTACT PROBLEM FOR INCLINED PLATE CONDITIONS OF EQUALITY OF ITS SOME DISPLACEMENT

Abstract

Porpose. Calculation of the plate on flexible base where one part of the points of the plate base are in the same inclined plane during bending. The concrete foundation where a base plate is located is an flexible semi-infinite foundation. Method. To determine a contact voltage between the plate and the foundation the Zhemochkin method is used. The system of canonical equations includes the equations of the Zhemochkin method and the equation to find single points of the slab in the inclined plane. The result of solving the system determines the forces in the method of Zhemochkin and unknown forces causing the displacement of the base plate of the foundation in the same inclined plane. Then the displacement of the base plate and the forces in it are found. Results. Calculation of the metal foundation of an eccentrically compressed metal column with an I-beam cross-section based on a concrete surfacing. Isolines of equal contact voltages and displacements, graphs of voltage and displacement with the typical sections of the foundation are shown.
