FHWA Launches Aerodynamics Webinar Series

A new Aerodynamics Webinar series sponsored by the Federal Highway Administration (FHWA) will discuss the unique challenges to bridge engineering presented by the effects of wind load and pressure.

While wind pressure directly adds to bridge structural loads, dynamic effects from winds can also accumulate and become hazardous. Other highway structures can be affected as well, including traffic signs and lighting structures.

The free Webinars will present information on the history of bridge aerodynamics, lessons learned from past cases, current code provisions, available tools for analysis, and mitigation methods.

“This series is designed to help bridge engineers recognize potential issues with new designs or on existing bridges, identify countermeasures, and find resources to help address the issues,” said Harold Bosch of FHWA.

Webinar topics will range from the daily work performed and decisions made by bridge engineers to cutting edge research initiatives. The series kicked off November 25, 2013, with an overview of the FHWA Aerodynamics Program. Upcoming sessions will feature:

  • Introduction to wind hazards in highway engineering—January 2014.
  • Wind load and aerodynamic design of bridges—March 2014.
  • Wind-induced vibration of bridge cables—May 2014.
  • Experimental methods for wind design—June 2014.
  • Computational tools for aerodynamics of highway structures—July 2014.
  • Coastal wind hazard to bridges: hurricane, surge, waves—August 2014.
  • Wind load and aerodynamic design of signs, signals, and lighting structures—September 2014.
  • Field monitoring and testing—October 2014.
