Operational durability of reinforced concrete structures

The resistance properties of reinforced concrete and reinforcement, required for modeling the degradation and calculations of the durability of reinforced concrete elements under the conditions of various types of corrosion damage, based on analytical and experimental data are substantiated. A probabilistic model has been developed for predicting and estimating the durability and reliability of reinforced concrete elements, taking into account the statistical variability of the calculation parameters and the kinetics of degradation processes during long periods of operation. Methods are proposed for calculating and predicting the durability of reinforced concrete elements based on deterministic probabilistic models of degradation of structural elements operating under aggressive environmental influences
