System reliability accounting for corrosion-induced degradation over time

Abstract

The remaining lifetime of concrete structures subjected to chloride-induced corrosion has been studied in many papers. However, few studies so far consider explicitly experiences from case studies, jointly several corrosion mechanisms and a system perspective. This paper introduces a methodology to evaluate the time-dependent system reliability for concrete bridges subjected to reinforcement corrosion. Here, both chloride and carbonation induced corrosion is jointly considered building upon the thermodynamic conditions for corrosion. The corrosion propagation is modelled with a structural system reliability analysis where different structural system models for repair and replacement consequences are developed. The developed approaches... (More)

The remaining lifetime of concrete structures subjected to chloride-induced corrosion has been studied in many papers. However, few studies so far consider explicitly experiences from case studies, jointly several corrosion mechanisms and a system perspective. This paper introduces a methodology to evaluate the time-dependent system reliability for concrete bridges subjected to reinforcement corrosion. Here, both chloride and carbonation induced corrosion is jointly considered building upon the thermodynamic conditions for corrosion. The corrosion propagation is modelled with a structural system reliability analysis where different structural system models for repair and replacement consequences are developed. The developed approaches and models are applied to a bridge case study and the service life extension is quantified.
