Beam Stability: Lateral and Torsional Bracing

Register

Presented by: Todd Helwig, Ph.D., P.E.

This lecture will cover design requirements for the bracing of beam systems. Several design examples will demonstrate the effective use of the AISC Specification Appendix 6 provisions. These examples will include relative, nodal, and lean-on applications. The uses of the provisions covered in the Specification Appendix as well as modifications covered in the Specification Commentary will be addressed. The importance of brace connection details is emphasized. Both building and bridge engineers will find useful information that can be incorporated into their beam designs. 

This is an encore presentation of Night School 31, Session 5: Beam Design and Stability -- Beam Bracing.

His primary area of interest is the design and behavior of steel structures with an emphasis on full-scale testing, field monitoring, structural stability, fatigue, and stability bracing requirements. 

He is a member of several technical committees within the American Institute of Steel Construction (AISC), the AISI/AASHTO T14 Steel Bridge Task Force and Design Advisory Group for Steel Bridges, the AASHTO/National Steel Bridge Alliance Collaboration Committees T11 (Design) and T13 (Analysis) and the Structural Stability Research Council (SSRC).  He is a member of the AISC Committee on Specifications.  He is the past chair of SSRC.

He has developed a taught numerous Shortcourses on the design and behavior of steel buildings and bridges on behalf of AISC, SSRC, and the National Highway Institute.  More than 5000 engineers have attended his Shortcourses in person with thousands more attending webinars.  

His research has been recognized with several awards including the 2022 Richard S. Fountain Award given by AISC/AASHTO/NSBA, the 2022 AISC Lifetime Achievement Award, the 2017 AISC T. R. Higgins Lectureship Award, the AISC Special Achievement Award, the ASCE Collingwood Research Prize, the ASCE Moisseiff Award, and the ASCE Shortridge Hardesty Award.
