Tech Note W601-23, Design Methodology for Hole Reinforcement of Cold-Formed Steel Compression Members

Summary:

Cold-formed steel compression members, e.g., wall studs, are sometimes damaged inadvertently by other construction trades.  An all-too-common damage is the cutting of large holes in either the flange or web elements of the cross section.  In situations where the cross section of the cold-formed steel member has been compromised by the cutting of holes, the member must either be replaced or reinforced.  This Tech Note discusses methodologies for engineering a reinforcement solution for a field cut hole in either the flange or the web element.  The Tech Note presents a reinforcing concept to achieve the desired required strength of the section.
