These details were developed by the Light Gauge Steel Engineers Association (LGSEA) for the North American Steel Framing Alliance (NASFA). They are intended to provide designers and contractors with guid- ance on design, detailing, and construction of low-rise residential buildings that utilize cold-formed steel framing members. Details contained in this document were selected based on their cost effectiveness at the time of this publication. Efforts have been made to present accurate, reliable, and useful information. The connections between members are shown as screw connections; other types of connections such as welds, bolts, powder-actuated fasteners, clinches, or pneumatically driven fasteners are acceptable. Although it is common for cold-formed steel framing members to have web “punchouts” for passing brac- ing or utilities, punchouts are shown in some details only. Punchouts are acceptable and vary in size, configuration, and spacing depending on the manu- facturer and/or design. NASFA acknowledges Nader Elhajj, P.E., for assem- bling and drafting the details. Special appreciation is extended to Kevin Bielat of the American Iron and Steel Institute (AISI) and Tim Waite of NASFA for their assistance and guidance. NASFA recognizes the following LGSEA com- mittee members who helped select the details contained in this document: Don Allen BLB Consulting Tim Waite North American Steel Framing Alliance Scott Shaddix Nicholas Lane Contractors Mike Whitticar Ener
