Numerical evaluation on the effect of steel bar corrosion on the cyclic behaviour of RC bridge piers

Reinforced concrete (RC) bridges exposed to marine environments significantly suffer from steel bar corrosion. Steel corrosion is responsible for strength deterioration of and material, damage in steel-concrete bond, spalling cover concrete, so on. This study presents a numerical model that can simulate the structural behavior corroded RC bridge piers under seismic action. In model, corrosion-induced modelled through different constitutive laws cracking, properties, bond between concrete. The validated using experimental studies available literature. obtained analysis, i.e., lateral load resistance capacity, cracking length crack patterns are good agreement with study. analysis results demonstrated rebar deteriorates performance (i.e., displacement etc.) piers. findings this will be useful assessing residual columns
