Abstract. The paper systematizes the main criteria necessary to determine the standard service life of concrete and reinforced concrete structures; the state of domestic and foreign regulatory framework is analyzed in terms of requirements for the service life of reinforced concrete structures; the main normative and technical documents are considered in the field of life cycle design of reinforced concrete structures of buildings and constructions. The types of corrosion damages of reinforced concrete structures and their determining factors are described; the internationally agreed models of durability for some degradation processes are given. On the basis of the work carried out, proposals were prepared to assess the corrosion state of the exploited reinforced concrete structures, their residual bearing capacity, operational serviceability, expected service life under specified aggressive actions, and methods for determining the standard service life of reinforced concrete structures. Proposals for the development and updating of a number of relevant regulatory, technical, organizational and methodological documents are given.
Key words: concrete and reinforced concrete, durability, service life, models, calculations, serviceability criteria, maintenance strategy, life cycle design, codes of rules, standards. - REFERENCES
