BIFURCATIONAL STABILITY OF A SYSTEM CONSTRUCTION BASED ON A FOUNDATION LAYER WITH Non-linearity OF ITS PROPERTIES

Abstract

In the article results of calculation of a critical load for system «a construction - a base plate - a layer of the basis » are considered within the limits of a flat problem. The model of system uniting absolutely rigid construction on a deformable base plate, cooperating with physically nonlinear layer of the basis is shown, allowing to reduce a problem of stability of a construction to a problem about own values
