Durability Assessment of an RC Railway Bridge Pier under a Chloride-Induced Corrosion Environment

摘要

Reinforcement corrosion caused by chloride is one of the major reasons of reinforced concrete durability failure, and chloride in RC railway bridge is mainly derived from marine environment. Therefore, a resistance degradation model of axial compressed structure calculated on bearing capacity limited state is established against the background of the marine environment, considering the deterioration of reinforcement and concrete. Consequently, durability assessment of a coastal railway bridge pier is made by way of the reliability calculation program.
