The　analysis　of　reinforced　concrete　(RC)　infrastructure　in　aggressive　environments　is　a　rather　challenging　task.　Nonetheless,　it　is　essential　to　design　new　structures　as　well　as　to　predict　the　residual　life　of　existing　constructions　and　to　plan　suitable　maintenance　interventions.　Therefore,　this　work　illustrates　the　preliminary　version　of　a　comprehensive　numerical　framework　conceived　to　assess　the　evolution　in　time　of　the　capacity　of　RC　structures　exposed　to　chlorides,　with　focus　on　bridges.　A　nonlinear　dynamic　model　is　first　developed　by　means　of　the　finite　element　method　in　the　attempt　to　simulate　the　transport　of　chlorides,　taking　into　account　binding　capacity　of　concrete　as　well　as　the　effects　due　to　temperature　and　moisture.　This　model　is　then　employed　to　estimate　the　free　chloride　content　during　the　lifetime.　Such　a　result　is　finally　used　to　evaluate　the　corrosion　current　density　and　the　pitting　corrosion　of　the　reinforcing　bars　in　order　to　estimate　the　pier　capacity.　©　The　Author(s),　under　exclusive　license　to　Springer　Nature　Switzerland　AG　2024.
