•An improved reinforced concrete steel bar deterioration model that incorporates pitting corrosion is proposed.•Change in after-cracking corrosion rate is considered to assess the time-dependent seismic fragility of RC bridges.•Differences in the results when reinforcing steel is subjected to genera...
