TRB conducted a webinar on Wednesday, February 10, 2016 from 2:00PM to 4:00PM ET that explained the basic principles of seismic isolation for improving the earthquake performance of bridges and give examples of hardware now available to achieve this performance. This webinar will gave an overview of the fourteen design examples in Appendix B of the 4th edition of the AASHTO Guide Specification for Seismic Isolation Design (2014).
This webinar was organized by the TRB Standing Committee on Seismic Design and Performance of Bridges. A certificate for 2.0 Professional Development Hours (PDHs) was provided to attendees who register and attend the webinar as an individual. Contact Reggie Gillum at
RGillum@nas.edu for instructions on receiving a copy of the recorded webinar.
Here are the slides from the presentation
Webinar Presenter
- Ian Buckle, University of Nevada Reno
Moderated by: Rich Pratt,
Alaska Department of Transportation and Public Facilities
Webinar Outline
- Seismic isolation design versus conventional seismic design for bridges
- Principles of seismic isolation: four components of an isolation system
- Examples of bridge applications
- Design of a bridge isolation system
- Additional sources of information: FHWA and AASHTO publications

At the end of this webinar, participants will be able to:
- Describe the basic purpose of seismic isolation
- List the four components of a viable isolation system
- Calculate displacements and base shear in an isolated bridge using the Simplified Method
- List bridge types/configurations that are not practical for the application of seismic isolation
- Describe the family of design examples published in the 4th Edition of AASHTO Guide Specification (2014).
