The Steel Joist Institute is again offering its “Diaphragm Design That Makes Sense: How to Design and Specify Steel Deck by Representatives of the SDI” webinar. It is scheduled for Wednesday, June 21, from 3:00 p.m. to 4:15 p.m. (EST), followed by a 15-minute Q&A session.

Diaphragm connection design has become more complicated and time consuming, due to recent changes in design codes and construction practices. This webinar identifies those changes, provides design guidance, reviews upcoming publications and introduces new SDI design tools.

Attendees will learn about recognizing appropriate AISI and SDI Standards and literature, and understanding the limits of existing shear tables and evaluation reports. Additional learning objectives include design procedures for uniquely shaped and sloped structures, as well as design procedures and shear capacities over CF framing.

Individual and site registration is now available online at Individual registration cost is $75. Each person who registers will receive his or her own link to the webinar and earn 0.15 CEUs or 1.5 PDHs and receive a certificate of completion from SJI. Site registration is also available for $300, allowing multiple attendees from the same company to utilize one link to the webinar.  

Besides setting standards for the steel joist industry, the Steel Joist Institute works closely with major building code bodies throughout the country helping to develop code regulations regarding steel joists and Joist Girders. The Institute also invests thousands of dollars in research related to steel joists and Joist Girders and offers a complete library of publications and other training, research and design aids. The Steel Joist Institute is a not-for-profit organization. For more information, visit or join the Steel Joist LinkedIn group.

The Steel Joist Institute is located at 234 W. Cheves Street, Florence, SC 29501.
