LIQUEFACTION ASSESSMENT METHODOLOGIES FOR SEISMIC BRIDGE DESIGN AND THEIR APPLICATION TO NEW YORK CITY PROJECTS

Current state-of-practice methodologies for evaluating seismic liquefaction potential and their applications to bridge design are presented. Issues involved in the assessment of liquefaction hazard at a bridge site are discussed, including soil susceptibility, seismological parameters, and site response. An evaluation of soil resistance using empirical procedures is provided. Examples are given for 2 bridge projects in the New York City (NYC) metropolitan area, analyzed using the 1998 NYC Department of Transportation Seismic Criteria Guidelines. Methodologies based on field tests were applied, and comparisons are made between these methodologies. Design recommendations are outlined for the 2 bridges, including site-specific response spectra and equivalent safety factors against liquefaction. Suggestions are made for defining and selecting appropriate design parameters for areas of moderate seismicity.
