Seismic Design Considerations for Carolina Bridges 

Presented By: Ty Stokes, HDR
Description: Seismic design is an important consideration for bridges within western states where large population centers are subject to significant seismic hazards. However, there is also a significant portion of the central and eastern US where seismic considerations play a critical role in bridge design. This presentation will focus on an overview of the seismic design practices of South Carolina, including information regarding specifications, detailing, material requirements, and liquefaction considerations, but will also include a discussion and comparison of practices from other central and eastern US states where seismic design is required for bridges. The example practices discussed will be compared with those from western states to highlight key similarities and differences.
