Technical References

The Department has adopted new seismic design procedures and tools for developing Acceleration Response Spectra (ARS) for bridge structures and has updated the Seismic Design Criteria (Appendix B) to reflect these changes. Guidelines and tools available used to create ARS curves are provided below.
