TRC1901 - Spatial Analysis of Benefits of Site Specific Ground Motion Response Analysis

项目名称：	TRC1901 - Spatial Analysis of Benefits of Site Specific Ground Motion Response Analysis
摘要：	For most projects, the general procedure of the AASHTO Guide Specifications is sufficient to determine seismic hazard and site response. However, it is appropriate and may be necessary to perform site-specific hazard analyses for cases involving special aspects of seismic hazard such as high ground motion values, essential bridges, specific soil sites, and near fault conditions. The result of site-specific hazard analyses may be used as justification for reduction in the spectral acceleration determined from the general procedure representing the uniform seismic hazard. Preliminary results from TRC1603 and results from MBTC3032 indicate that seismic demands can be reduced in portions of Arkansas by conducting a site-specific ground motion response analysis (SSGMRA), which is expected to have economic benefits regarding the construction of bridges and embankments. 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) officials to determine when SSGMRA should be conducted and possible cost savings. A cost-benefit analysis will be performed at the conclusion of this project to determine the cost saving based on the type, size, and the location of the bridge. Objectives include the following: Obtain site specific shear-wave velocity profiles for 20 sites, in addition to the 15 previously surveyed sites done through TRC1603 and other sites completed for TRC0803; Collect soil boring logs; Perform site-specific analysis; Prepare ground surface contour maps; and Develop documentation and specifications for use with future projects where site-specific studies are needed.
