Preliminary Investigation of the Seismic Vulnerability of the Alaskan Way Viaduct
The University of Washington (UW) team reviewed the Washington State Department of Transportation (WSDOT) report titled 'Earthquake Analyses of the Alaskan Way Viaduct' and performed an independent assessment of two typical sections of the structure. Additional analyses were performed to investigate the influence of some factors that were not considered in the WSDOT report. The input motion and geotechnical characteristics assumed in the WSDOT report were consistent with the information available to the WSDOT and to the UW. However, the paucity of information available regarding the seismological risk and the subsoil conditions precluded the possibility of reliably estimating the input motion, foundations stiffnesses, foundation capacities, and potential for liquefaction. Inspection of the structural plans suggested that timber-concrete spliced piles in the section of the structure built by the WSDOT might be particularly vulnerable. The elastic dynamic models generated by WSDOT and those constructed for the study were found to give comparable natural periods in the first three modes.
