TRB Webinar: Classifying Fracture Critical Members

TRB conducted a webinar on Thursday, June 7, 2018 from 2:00 PM to 4:00P M ET that that discussed the concept of fracture critical members (FCMs) in steel bridges. Over the past decade, there have been various notions about what constitutes an FCM, but it was not clearly defined. This webinar presented recent research and specifications on methods to establish if a member should be classified as an FCM or not.  Presenters provided background to the development of the proposed guide and provide examples about how to evaluate internal member-level redundancy of mechanically-fastened built-up steel members. This webinar also explored how the proposed guide specifications could be applied to twin tub girder bridges in the context of system behavior.

This webinar was organized by the TRB Standing Committee on Steel Bridges. 

The slides are available. Contact Reggie Gillum at RGillum@nas.edu for a copy of the recorded webinar.
