| Abstract | Deterioration of reinforced concrete (RC) bridge columns due to reinforcement corrosion is a significant problem for aging infrastructure exposed to cold weather conditions, such as those found in Canadian winters. Corrosion-induced damage in aging bridge columns subjected to service loads can lead to significant reduction in their structural capacity and premature failure. This research presents a 3D numerical model using ABAQUS software to evaluate the structural response of large-scale RC columns subjected to eccentric load and reinforcement corrosion. The 3D numerical model evaluates and predicts RC structural behaviour for two different patterns of corrosion exposure: (i) corrosion of two ties at the mid-section of the column with cover stiffness reduction, (ii) corrosion in the compression rebar and cover stiffness reduction. The numerical model is validated with experimental work conducted on smallscale RC columns at the University of China. Results of the models are analyzed in terms of concrete and reinforcement response in addition to the lateral displacement at the mid-section of the column. |
