Based on analytical and experimental data, the durability properties of reinforced concrete and reinforcement necessary for modeling degradation and calculating the durability of reinforced concrete elements under various types of corrosion damage are substantiated.
A probabilistic model has been developed for predicting and assessing the durability and reliability of reinforced concrete elements, taking into account the statistical variability of design parameters and the kinetics of degradation processes during long periods of operation. An analysis of the method 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 has been carried out.
The necessary assessment of the stress-strain state of reinforced concrete structures under conditions of long-term operation in aggressive environments as a result of corrosion damage is given, and their residual life is studied, taking into account the reduction in the cross-sectional area of concrete and reinforcement
Key words: durability / reliability of reinforced concrete structures / residual life / corrosion damage
