ANALYSIS OF EXISTING DEGRADATION CRITERIA IN PREDICTING THE TECHNICAL CONDITION OF TRANSPORT STRUCTURES

Artur Onyshchenko Oleksandr Davydenko Yana Dukhnenko

The article is dedicated to the urgent issue of managing the reliability and durability of transport structures. Modern scientific approaches to assessing the technical condition of transport structures, based on the analysis of the degradation of elements throughout their life cycle, are considered. The article presents the advantages and disadvantages of the most common models for predicting the technical condition of building structures. Each model applies a characteristic degradation criterion for the structure: load-unload cycle, accumulation of a critical amount of chlorides, intensity coefficient, geometric parameter(s) of cracks in the material, reliability, etc. The issue of selecting the control parameter for the life cycle model of bridge elements is analyzed. The theoretical basis for the model of damage accumulation and the degradation model based on the physical and mechanical characteristics of the material is formulated. Depending on the stage of the life cycle, the appropriate type of prediction model is proposed. The prediction model for the technical condition of bridges adopted in the regulatory documents of Ukraine is discussed
