The Transportation Research Board (TRB) Technical Activities Division presents the following webinar on Transportation and Infrastructure: Climate Change Impacts on the Seismic Performance of Bridges. The TRB is a National Academy of Sciences, Engineering, and Medicine division. Its mission is “to mobilize expertise, experience, and knowledge to anticipate and solve complex transportation-related challenges.”
Climate change phenomena such as scour, sea level rise, tsunamis, and permafrost degradation significantly influence bridge durability and performance during seismic events. The TRB hosts a webinar addressing the effects of climate change on bridges’ seismic resilience and discussing mitigation strategies. Presenters provide recommendations and approaches to mitigate these impacts.
This webinar is informed by Special Report 290, titled “Potential Impacts of Climate Change on U.S. Transportation. This report examines the implications of climate change for U.S. transportation infrastructure and operations, summarizes the scientific consensus on relevant climate changes, and discusses the limitations in current scientific understanding regarding timing, magnitude, and geographic distribution.
Further, Special Report 290 identifies potential impacts on transportation and suggests adaptation strategies and research directions. Contributors to TRB Special Report 290 include the National Research Council, the Transportation Research Board, the Division on Earth and Life Studies, and the Committee on Climate Change and U.S. Transportation.
This webinar is sponsored by the TRB Standing Technical Committees on Foundations of Bridges and Other Structures, Seismic Design and Performance of Bridges, Safety and Security of Bridges and Structures, and Extreme Weather and Climate Change Adaptation.
Learning objectives. At the end of this webinar, participants will be able to: “gain insight into how climate change impacts bridge structures, including the growing risk of liquefaction; understand how practitioners are actively addressing current challenges posed by climate change; and address the effects of climate change on bridge structures using recommended actions.”
Webinar agenda and presenters:
- Alaska perspective on how climate change impacts bridge design – Nicholas Murray, Alaska Department of Transportation & Public Facilities
- Importance of codification for climate change challenges in bridge seismic design – Sissy Nikolaou, National Institute of Standards and Technology
- Warming permafrost, climate change, and its impacts on seismic design and increased liquefaction hazard – John Thornley, WSP
- California’s response to climate change and seismic design – Christopher Traina, California Department of Transportation
- Question and answer session moderated by Ariadne Palma Parra, North Carolina State University
