WEBINAR ON RADIUSED COLD-FORMED STEEL STRUCTURE DESIGN

April 30, 2026 | 3:00 p.m. Eastern

Presenters: Josh Garton, P.E., S.E., Daniel Linneman, P.E., S.E.

Presentation Outline

This presentation explores the challenges of designing radiused cold-formed steel (CFS) members from a practical engineering perspective. While traditionally used in straight applications, radiused CFS members offer a versatile, lightweight, and cost-effective option for radiused structures, but require careful analysis to ensure adequate strength and performance.

The session will focus on several key areas:

• Curving Cold-Formed Steel Members:Techniques such as stretch forming, crimping, and tabbed assemblies are required to curve CFS members, altering their strength and stiffness compared to standard designs. We'll discuss each method’s benefits and limitations in various scenarios.
• Evaluating Projects for Radiused CFS Applications: Radiused layouts aren’t always practical or cost-effective. We’ll explore criteria like architectural intent, load paths, framing orientation, and fabrication constraints to assess when radiused CFS members are a good fit. Examples of successful projects will provide a decision-making framework.
• Capacity and Torsional Behavior: Understanding how radiused CFS members behave under bending and torsion is key to ensuring performance. While torsion can often be avoided, in some cases it’s the most efficient option. We’ll look at how curvature impacts forces, deflection, and member design, focusing on built-up sections.
• Delegating Design Responsibilities: Designing radiused members involves collaboration among engineers, delegated designers, and fabricators. We’ll address how to delegate radiused framing by establishing performance criteria and minimum properties to meet your design intent, considering how the manufacturing processes can affect strength and stiffness.
• Connection Detailing for Curved CFS Members: Detailing connections for curved members poses unique challenges, often exceeding standard detailing practices. We’ll discuss strategies for handling these non-standard loads and restraints, ensuring connection integrity.
• Design Examples (time permitting): A walk-through of the design process for a radiused CFS member will conclude the session, covering manufacturer capacity adjustments, torsional design, and connection detailing.

This presentation will provide practical guidance for engineers working with radiused CFS members, offering insights into design, evaluation, and detailing techniques.
