Riverbed Scouring Effect in Bridge Pile Foundation during Earthquake
This paper focuses on the issues that riverbed scouring causes in piles and pier of a balanced cantilever box girder bridge during a seismic event. Finite element model of a 9-span balanced cantilever box girder bridge with ANSYS was developed for the analysis. Earthquake was applied both in parallel and perpendicular directions to the traffic of the bridge by single point response spectrum analysis while varying the riverbed scouring depth. Moment in piles increases 137% and 87% about original no scouring condition for earthquake in perpendicular direction of traffic and parallel direction of traffic, respectively. While the percent decrement of pier moment, about original no scouring condition, for earthquake in perpendicular direction of traffic and parallel direction of traffic is 59% and 67%, respectively. Capacity ratios of the bridge pile were also observed using CSiCOL and scouring depth at which capacity ratio exceeds 1 was calculated.
