Significant changes have been made recently to AASHTO Load Resistance Factor Design (LRFD) Bridge Design Specifications pertaining to shear studs on steel bridges. TRB hosted a webinar on Thursday, June 22, 2023 from 2:00 PM to 3:30 PM Eastern that discussed recent research efforts into the behavior of headed shear studs in composite bridge girders and address recent design provision changes. Presenters provided an overview of recent updates to the shear stud fatigue provisions and new provisions for clustered stud configurations. Presenters also shared supporting research involving both analytical and experimental shear stud investigations.
This webinar was sponsored by TRB’s Standing Technical Committee on Steel Bridges.
The slides are available. Please contact email@example.com for a link to the recording. There may be a $90 fee.
