A Modified Semi-Probabilistic Approach for the Assessment of the Residual Service Life of Reinforced Concrete Structures Subjected to Carbonation

摘要

This paper presents a modification of an existing semi-probabilistic model that is used for estimating the residual service life of reinforced concrete structures subjected to carbonation. Generated MATLAB codes are used for the estimation of the residual service life for cases where the parameters considered are not necessarily normally distributed through the application of the theory of reliability. Monte Carlo simulation is also performed to validate the results of the modified model and to introduce a practical approach that can be used for the estimation of the residual service life of deteriorated reinforced concrete structures due to carbonation. The modified model is validated using existing data available in literature and is expected to serve as an efficient and user-friendly design tool that is able to deliver an estimation of the residual service life of deteriorated reinforced concrete structures due to carbonation.
