Reinforced concrete bridge piers and deck slabs can be exposed to severe rebar corrosion when they exposed to corrosive environments. In this study, the change in structural performance of the mid-piers of a reinforced concrete bridge projected to be built on Harşit River under various rebar corrosion scenarios was discussed. For this, the bridge structural system was first modeled and two different corrosion scenarios were applied to the bridge midpiers. Subsequently, dynamic analyses were performed for each scenario using 7 different earthquake acceleration records according to EC-8 to evaluate the structural performance of the bridge mid-piers. As corrosion levels increased, structural performance of reinforced concrete bridge mid-piers decreased. In addition, the rotation demand has increased in corroded elements. This situation was evaluated as more damage than usual on the bridge mid-piers during the earthquake.
