Abstract
Static seismic analyses are used to characterize the vulnerability of an older-vintage bridge to liquefaction and lateral spreading. A sensitivity study is performed by varying key parameters and observing their influence on the predicted free-field lateral spreading displacement required to mobilize damage states ranging from minor damage to collapse. The thickness of the nonliquefiable crust layer was found to be the most influential parameter. Published fragility curves were reasonably consistent with the displacements required to cause major damage and collapse of the bridge.
