Case study – Reliability assessment of a bridge subject to chloride induced correosion and associated structural deterioration (section 9.19)

Kapitola, resp. kapitoly v odborné knize

The preservation of an adequate safety level in concrete bridges subject to gradual degradation due to the in-service effects of traffic and environmental actions is commonly an expensive, and sometimes problematic, task. Chloride ion ingress is an important factor influencing both durability design and throught-life care issues, especially in regions where winter de-icing salt application for traffic safety reasons is common, e.g. for highway structures. The following example introduces a feasible approach for the analysis of potential chloride induced corrosion and associated deterioration. It is presented in the context of an actual highway bridge application.
