Design Methodology for Hole Reinforcement of CFS Bending Members

April 2015

The Cold-Formed Steel Engineers Institute 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 https://shop.steel.org/c/48/cfsei-tech-notes.
