Updated South Carolina Department of Transportation Seismic Design Specifications for Highway Bridges

South Carolina is located in the most active seismic region on the east coast of the United States. In order to address seismic design needs, the South Carolina Department of Transportation (SCDOT) developed and implemented the Seismic Design Specifications for Highway Bridges in 2001. Since then, SCDOT has gathered input from bridge designers, geotechnical engineers, contractors and other government agencies. Based on this input, SCDOT is incorporating recent research results and newly developed seismic design methodologies to update the Specifications to fulfill SCDOT needs and standard practices of the State, including the SCDOT Seismic Hazard Maps Study, and standard construction details. Efforts have been made to attain consistency of the Specifications with SCDOT geotechnical engineering practice, and the newly developed Geotechnical Design Manual, to achieve the seismic performance requirements of the Specifications. The updated Specifications continue to require performance based design considering functional evaluation and safety evaluation levels of earthquake ground motions. This paper describes the SCDOT seismic design criteria, new findings since its implementation and the need for more research.
