Service Life Prediction of RC Member in Chloride Environments under Different Loading Level

Article Preview

Abstract:

Chloride ingress is a major factor affecting durability of reinforced concrete structures. In the present study, service life of a RC flexural member in chloride environments is predicted. First, model for service life is established considering model error and the coupling effects of loading condition and environmental factors on the chloride penetration. Then, service life is predicted in probabilistic framework of Monte Carlo simulation. The results show that the use of a lognormal distribution for the service life seems relevant; the service life shows a great scatterings.
