The Cold-Formed Steel Engineers Institute (CFSEI) has published Technical Note F104-24, “Design of Cold-Formed Steel Bearing Stiffeners.” Tech Note F104-24 covers the design of a C-section and track section profile used as web stiffeners.
Cold-formed steel (CFS) members consist of relatively slender (large width to thickness ratio) web elements, the web may experience buckling under concentrated loads. In CFS construction, these loading conditions can occur at interior or end support bearing locations. Thus, one design limit state to check in CFS design is the web crippling capacity of the member.
When the web crippling strength is inadequate, the most common remedy for avoiding web crippling due to concentrated loads is the use of a web stiffener. A web stiffener can take multiple forms, including Tech Note F100, Clip Angle Bearing Stiffeners, proprietary clip, C-section or track section.
This technical note will cover the design of a C-section and track section profile used as web stiffeners.
- Tech Note F104-24 is free of charge to CFSEI Corporate, Professional and Student Members
- For nonmembers, Tech Note F104-24 is available for purchase at CFSEI On-Demand
CFSEI Technical Notes are produced and updated by industry experts to educate design professionals on advancements and best practices in CFS design and construction.
Cold-Formed Steel Engineers InstituteThe Cold-Formed Steel Engineers Institute (CFSEI) comprises hundreds of structural engineers and other design professionals who are finding a better way to produce safe and efficient designs for commercial and residential structures with cold-formed steel.
CFSEI members work together to develop and evolve industry standards and design methods, produce and issue technical bulletins, and provide seminars and online training to improve the knowledge and skills base of engineers and design professionals. For more information, visit www.cfsei.org.
On May 1, 2023, CFSEI moved from the American Iron and Steel Institute to its new home with the Steel Framing Industry Association (SFIA), where the CFSEI’s leadership and goals will continue to be supported in its role as the industry’s key touchpoint for CFS design.
