CFSEI Updates Technical Note On Design Methodology For Hole Reinforcement Of Cold-Formed Steel Bending Members

CFSEI-Tech-Note-G900-15Washington, DC - The Cold-Formed Steel Engineers Institute (CFSEI) has updated its Technical Note titled “Design Methodology for Hole Reinforcement of Cold-Formed Steel Bending Members” (Tech Note G900-15). The document replaces Technical Note G900-08.

AISI S100, North American Specification for the Design of Cold-Formed Steel Structural Members, does not provide guidelines for the reinforcement of holes in cold-formed steel members. This Technical Note provides a methodology for engineering a reinforcement solution for either the flange or web elements of a stud or joist. The discussion includes an example problem.

The just-published Technical Note G900-15 includes revised references to the most recent edition of the North American Specification, AISI S100-12. It also includes revised and updated calculations for the example problem.

The document is available free of charge to CFSEI members, and is available for purchase by non-members from the AISI Online Store at For more information on joining CFSEI, visit

CFSEI maintains a Steel Framing Hotline to answer inquiries from construction professionals seeking cold-formed steel solutions for their projects. Suggestions for additional Technical Note topics are welcomed. The Steel Framing Hotline is accessible at 1-800-79-STEEL.
