OTREC-RR-11-22This project developed a seismic model for Oregon truck routes using Risk for Earthquake Damage to Roadway Systems (REDARS2) and HAZUS MH. We refined data from the first model to more realistically represent bridge inventory, address the seismicity of the Pacific Northwest (PNW), conduct sensitivity analyses of soil data and develop a seismic network model of Oregon bridges to assess roadway vulnerability. Assumptions were reviewed and Oregon data was
