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.　©　Fédération　Internationale　du　Béton　-　International　Federation　for　Structural　Concrete.
