The Short Span Steel Bridge Alliance (SSSBA) will host a free 60-minute webinar on “Innovative, Cost-Effective Options for Short Span Steel Bridge Design” on Tuesday, May 12, from 2 p.m. - 3 p.m. EDT. The webinar is being held in cooperation with the American Iron and Steel Institute (AISI) and the American Galvanizers Association (AGA) as part of Infrastructure Week 2015, a national outreach event taking place May 11-15 to build awareness and educate policymakers and the public about current infrastructure challenges in the U.S.

Conducted by Greg Michaelson, Ph.D., professor at the Weisberg Division of Engineering at Marshall University, the webinar will present information on press-brake formed tub girder technology for short-span (140 ft or less) bridges and how they facilitate accelerated bridge construction (ABC) while also offering an economical and competitive design solution. The first two projects to use this new technology will be constructed this year in Iowa and West Virginia.

Michaelson will also discuss eSPAN140, a free, web-based tool that delivers customized  preliminary short span steel bridge designs in three steps and under five minutes, providing a “one-stop shop” for steel fabrication and erection details for standard designs for rolled beam, plate girder, corrugated structural plate and corrugated steel pipe structures.

This webinar is being presented as a special addition to AGA’s “Galvanize It!” webinar series and is approved for continuing education units (CEUs), learning units (LUs) and professional development hours (PDHs). Register for the webinar here.
