An　efficient　yet　accurate　procedure　was　developed　for　the　seismic　assessment　of　reinforced　concrete　(RC)　bridges　subject　to　chloride-induced　corrosion.　The　procedure　involves　using　incremental　modal　pushover　analysis　to　assess　corroded　bridges　as　an　alternative　and　less　computationally　demanding　approach　to　non-linear　dynamic　analysis.　A　multi-physics　finite-element　analysis　is　performed　to　evaluate　the　effects　of　chloride-induced　corrosion　on　bridge　columns.　In　doing　so,　chloride　ingress　in　concrete　is　numerically　simulated　as　a　diffusion　process　by　considering　the　effects　of　temperature,　humidity,　corrosion-induced　cover　cracking　and　concrete　aging.　The　estimated　chloride　concentration　is　then　employed　to　evaluate　the　corrosion　current　density,　from　which　the　effects　of　corrosion　on　reinforcement,　cracked　cover　concrete,　confinement　and　plastic　hinge　length　can　be　determined　for　subsequent　non-linear　static　analysis.　A　case　study　of　a　typical　bridge　structure　is　presented.　The　proposed　procedure　can　be　used　to　assess　the　seismic　performance　of　irregular　RC　bridges　exposed　to　severe　corrosive　environments.　©　2021　ICE　Publishing:　All　rights　reserved.
