ABSTRACT
A method to determine the residual life of building foundations according to displacements obtained by its characteristic nodes during its operation is proposed. Calculation procedures are presented and basic physical phenomena related to them are described. Based on the hypothesis for critical energy levels of building structures, basic relationships are derived, allowing estimating the residual life of building (structure) foundations. Simple examples describing main approaches to evaluation of the residual life of building foundations and the physical nature of calculation procedures are given.
