Originální abstrakt

A structure needs to be operated safely and economically throughout its service life. The essential step in the needed cost-benefit evaluation is the prediction of the performance of the structure as a function of time, with consideration also given to environmental actions, i.e. using service life modelling. The chloride-induced corrosion of steel in reinforced concrete structures is one of the major causes of their deterioration over time as chlorides from de-icing salts or a marine environment penetrate through the concrete cover with the potential to dissolve the protective layer of reinforcement. The present contribution discusses and investigates analytical chloride diffusion models that apply a stochastic approach in order to enable the assessment of a relevant reliability level. Attention has been paid to the time dependency of the diffusion coefficient and surface chloride.
