- Description
- The paper shows how spatial and time dependent modelling of deterioration process can be used to provide a more realistic assessment of the reliability, safety and maintenance options for reinforced concrete structures. The present paper will assess (i) the effect of pitting corrosion on safety and structural reliability and (ii) the effect of corrosion-induced cover cracking on the on the number, timing and extent of repair actions for RC structures. It was shown that probabilities of failure considering spatial variability of pitting corrosion were up to 80% higher than probabilities of failure obtained from a non-spatial analysis. Finally, the paper will discuss aspects of deterioration modelling in need of improvement that will enable predictions of the safety and maintenance needs of a structure over its service life to be made with more confidence.
