Multi-Hazard Life-Cycle Analysis of Flood-Scour Effects on Seismic Bridge Performance
A multi-hazard life-cycle methodology is used to assess the effects of flood-induced scour on the seismic system failure performance of bridge systems. Based on a case-study for a simple bridge system supported by shallow foundation systems, our results show that scour effects are time-varying: during the first 45 years, scour has insignificant effect on modifying the seismic vulnerability of the bridge in terms of two levels of system failures (i.e. extensive system damage or system collapse); after 65 years, scour dominates the cause to system failure; and while between 45 to 65 years, bridge scour and earthquakes jointly contribute to system failure. This result implies that caution is necessary for managing aging bridges serving in both seismicity and flooding active regions.
