TRB conducted a webinar on Monday, August 29, 2016 from 2:00PM to 3:30PM ET that focused on soil-foundation-structure interaction (SFSI). SFSI examines nonlinear interactions to determine the response of a structure during a seismic event. With the advances in computing and software, SFSI can be incorporated into the analysis and design of even small, conventional bridges. This webinar discussed basic SFSI concepts so that they may be included in seismic bridge design.
This webinar was requested by the TRB Standing Committee on Seismic Design and Performance of Bridges. A certificate for 1.5 Professional Development Hours (PDHs) was provided to attendees who registered and attended 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 Presenters
Moderated by: Elmer Marx,
Alaska Department of Transportation and Public Facilities
Webinar Outline
- General overview of the design process with a focus on a displacement-based process
- Types of SFSI and the impact on analysis and design
- Example with shallow foundations
- Example with deep foundations
- Techniques for including SFSI with equivalent linear analysis
The first 60 minutes of the webinar will be for presentations and the final 30 minutes will be reserved for audience questions. The Registered Continuing Education Program (RCEP) categorizes this webinar activity as relating to health, safety, and welfare including core technical.
Learning Objectives
At the end of this webinar, participants will be able to:
- List the steps necessary to develop foundation spring values
- Describe the effects of foundation flexibility on the push-over displacement check
- List several methods of approximating deep foundation stiffness

Professional Development Hour Information
A certificate for 1.5 Professional Development Hours (PDHs) will be provided to Professional Engineers (PEs) who register and attend the webinar as an individual. For groups,
only the person that registers and attends the session will receive a PDH certificate.
Individuals registered as Florida PEs are no longer required to email TRB with your license number to report your attendance. Instead, please use your certificate that TRB provides through RCEP.net as verification of your attendance to the Florida Board of Professional Engineers.
Please check with your licensing board to ensure that TRB webinar PDHs are approved by your board.
This webinar was developed in March 2016. TRB has met the standards and requirements of the Registered Continuing Education Program (RCEP). Credit earned on completion of this program will be reported to RCEP by TRB. Certificates of Completion will be issued to individuals who register for and attend the entire webinar session. Complaints about registered providers may be sent to RCEP, 1015 15th Street, NW, 8th Floor, Washington, DC 20005. Website:
