stages, the expected seismic resilience of bridges can be assessed including the impact of near-fault earthquakes. • The seismic resilience of the bridge in RM and SM condition have been compared and the relative error is about 4%, with more conservative results for RM. • Involving the uncertainties of the parameters in the functionality recovery functions, the relative errors in using the SM conditions may reach 15%. This indicates that the proposed method (RM) may significantly improve the accuracy of the seismic resilience assessment. In conclusion, the proposed method is recommended for assessing the seismic resilience of bridges located close to fault lines. Although these results are based on a particular steel-concrete composite bridge, they could serve as a useful starting point when examining other types of bridge. The calculation process and methodology presented in this paper could be employed to analyse the impact on various bridges at a regional level. For this, however, an additional database of vulnerable components would be required. This would certainly be a worthwhile extension to the present investigation.
