Beam Stability: Lateral and Torsional Bracing

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.
