The South Carolina Department of Transportation (SCDOT) Seismic Design Specifications for Highway Bridges (Specifications) have been developed to provide the Department's bridge designers with a guide to design criteria, analysis methods and detailing procedures for the preparation of highway bridge plans. These Specifications supersede the seismic design requirements of the AASHTO LRFD Bridge Design Specifications for seismic design and analysis of South Carolina bridges.
The primary function of the Specifications is to provide minimum requirements for use by bridge designers to achieve public safety in an earthquake that is likely to occur in the State of South Carolina. The implementation of the Specifications is intended to safeguard against major failures and loss of life, to minimize damage, to maintain functions, and/or to provide for expedited repair..
Each bridge presents a unique set of design challenges. The designer must determine the appropriate methods and level of refinement necessary to design and analyze each bridge on a case-by-case basis. The designer must exercise sound engineering judgment in the application of these Specifications. Therefore, these Specifications are not intended to preclude the exercise of individual initiatives in reaction to site-specific conditions or application of current state of the art practices. Any design exceptions to the Specifications shall be reviewed and approved by SCDOT in accordance with SCDOT standard procedures.
The Specifications were developed for SCDOT's use. SCDOT does not warrant the Specifications to be standards required by any other entity for purposes other than for SCDOT.
Updates
As the need arises, Bridge Design Memorandums will be issued to supplement or revise the requirements of the Specifications.
Order Information
Copies of the Specifications may be obtained, at a cost of $25.00 per copy, through the Department's Engineering Publications Office at (803) 737-4533 or at engrpubsales@dot.state.sc.us.
Consultant Seismic Information Request Form
Consultant requests for seismic hazard map information for projects shall be submitted to the appropriate Regional Production Group - Geotechnical Design Section. All requests shall be submitted using the Consultant Seismic Information Request - GDF 002 form. For questions on completing the form please refer to the Geotechnical Design Manual or contact the appropriate Regional Production Group - Geotechnical Design Section.
