This study is meant at understanding the influence of the pattern of corrosion due to chlorides-induced corrosion on the time-dependent cyclic behavior of reinforced concrete (RC) bridge columns. The chloride ingress in the cross-section of the column is simulated by a multiphysics FE approach taking into account both environmental and material factors. The non-linear cyclic responses of the RC bridge column under corrosion is evaluated by a nonlinear fiber model. A parametric study is finally conducted for a real case study, which aims at unfolding the role of the corrosion pattern on the time variation of capacity and ductility.

Abstract

This study is meant at understanding the influence of the pattern of corrosion due to chlorides-induced corrosion on the time-dependent cyclic behavior of reinforced concrete (RC) bridge columns. The chloride ingress in the cross-section of the column is simulated by a multiphysics FE approach taking into account both environmental and material factors. The non-linear cyclic responses of the RC bridge column under corrosion is evaluated by a nonlinear fiber model. A parametric study is finally conducted for a real case study, which aims at unfolding the role of the corrosion pattern on the time variation of capacity and ductility.
