Abstract
Multi-criteria prediction of the service reliability of load-bearing elements based on the application of mechanical and energetic criteria and theory of catastrophes, determines the relevance of the study. Multi-criteria prediction of the service reliability of load-bearing elements of bridge spans is an expansion of understanding and use of elements of catastrophe theory based on mechanical and energy criteria.
Purpose: The aim of this work is to consider multi-criteria prediction of the service reliability of bridge structures in thermodynamic state and adaptability of the material, elements and structures as a whole during a long operational period.
Research findings: Control parameters of the reliability forecasting process are determined based on equilibrium states, characterized and accompanying the instantaneousness of the deformation-catastrophic process.
