Review article

The problem of determining the longevity of engineering hydraulic engineering and port facilities has become extremely urgent with the development of the Northern Sea Route and the increase in oil production on the shelf. Most currently used methods of estimating the reliability of structures are based on the deterministic (historical and empirical) method, semi-probabilistic method and complete probabilistic method. Semi-probabilistic and probabilistic methods for assessing reliability were conceived with due regard for the uncertainty of the parameters affecting the durability of the structure in terms of the probability of its failure. In this approach, the control parameters of the problem were modeled as random variables. A complex semi-probabilistic model for the prediction of the service life of reinforced concrete structures subjected to the combined action of carbonization and chloride aggression is proposed, which is compared with chloride transport without carbonization and tested experimentally.
