Benefits of Performing Site-Specific Ground Motion Response Analysis—A Regional Case Study for Northeast Arkansas
The procedure included in the American Association of State Highway and Transportation Officials (AASHTO) LRFD Bridge Design Specifications is sufficient to determine seismic hazards and site response. However, it may be necessary to perform site-specific ground motion response analyses (SSGMRA) for cases involving certain aspects of seismic hazards, such as long-duration earthquakes, critical or essential bridges, specific soil, and near-fault conditions. According to AASHTO LRFD Bridge Design Specifications, the intent of conducting a site-specific hazard study is to develop ground motions and response spectra that are more accurate for local seismic and site conditions than can be determined from the United States Geological Survey (USGS) hazard maps. Fifty-one SSGMRA were performed in northeast Arkansas as part of the Arkansas Department of Transportation (ARDOT) TRC1901 research project. Geographic information system (GIS) maps were generated that can be used to determine potential cost savings if such a study is performed.
