Spatial Analysis of Benefits of Site Specific Ground Motion Response Analysis

The purpose of this study is to develop a decision tree or a geographic information system (GIS) map that can be used by the Arkansas Department of Transportation (ARDOT) to determine when site-specific ground motion response analysis (SSGMRA) should be conducted and possible cost savings. To achieve this goal, the researchers build upon the existing work by obtaining shear-wave velocity (Vs) profiles for 20 sites, in addition to 15 previously surveyed sites done through previously completed ArDOT projects. Site-specific hazard maps will be developed at the ground surface. At the end of the project, a contour map of PGA will be developed. Using GIS, bridges that will be built each year will be overlaid. Then, using the PGA contour map and the location of each bridge, the cost savings (the costs of performing the SSMGRA will be included) will be estimated. Finally, a set of specifications will be provided to ARDOT to be used to assess the qualification of hazard analysts as well as requirements needed for an analyst to perform a successful SSGMRA.
