Behaviour of Reinforced Concrete In Case Of Corrosion under Serviceability According To Is 456

Abstract

Reinforcement corrosion is a common cause of deterioration of cement in reinforced concrete. The corrosion mechanism involved and the consequent structural behaviour of deteriorated reinforced concrete members have been studied by several researchers. Nevertheless, the knowledge obtained is primarily based on experimental investigations of artificially corroded specimens whereas natural corrosion may affect structural behaviour differently. This paper aims to deepen the numerical understanding of the structural effects of natural corrosion deterioration with a focus on the remaining anchorage capacity between deformed bars and concrete, as well as the investigation of possible links between visual inspection data and structural damage.
