Past
Do you need a “back to basics” refresher about seismic bridge design? TRB hosted a webinar on Thursday, July 16, 2020 from 2:00 PM to 3:30 PM Eastern that focused on modeling and analysis of real-world bridges subjected to earthquake loading. The webinar featured specifications for load and resistance factor design (LRFD) in accordance with the AASHTO guide. Presenters identified seismic hazards and discuss structural dynamics and modeling.
This webinar was organized by the TRB Standing Committee on Seismic Design and Performance of Bridges.
The recording is available.
Webinar agenda and presenters
- Seismic hazards and seismic demands in bridges: Tom Ostrom, California Department of Transportation
- Structural dynamics for seismic analysis: Lee Marsh, WSP
- Modeling for seismic demands: Derek Soden, S. Federal Highway Administration
- Question and answer session: Moderated by Elmer Marx, Alaska Department of Transportation and Facilities
The first 60 minutes of the webinar will be for presentations and the final 30 minutes will be reserved for audience questions.
Learning Objectives
At the end of this webinar, participants will be able to:
- Identify different types of seismic hazards and determine how bridge engineers minimize the potential for earthquake-induced bridge damage or collapse
- Develop a conceptual understanding of seismic structural dynamics without complicated mathematics
- Describe structural model types and modeling methods
- Select an appropriate model type and modeling method to analyze the seismic response of a bridge, and develop, test, and verify computer models for seismic evaluation
Professional Development Hour Information
Professional engineers (PEs) who register and attend the entire webinar as an individual will be awarded 1.5 Professional Development Hours (PDHs). TRB’s webinar program awards PDH credits only to the registered individual, and not to other members of a group that view the webinar together. To be eligible for the credits, individuals must remain signed in for the entire webinar, including for any question and answer session following the presentations.
