Tech Note B005-20: Introduction to Cold-Formed Steel Framing Design Aids
$5.00
Summary: Both steel industry and manufacturers’ associations provide design aids that assist engineers with the proper application of the cold-formed steel design challenges. Design examples and design aids are essential to educate an engineer in the proper use and design of cold-formed steel members, connections and assemblies. This Tech Note provides an overview of some of the available cold-formed steel framing design aids.

Tech Note 562-22: Powder-Actuated Fasteners in Cold-Formed Steel Construction
This Technical Note updates and replaces Tech Note 562
Summary: Power-actuated fasteners (PAF’s) are industry standard for attachment of cold-formed steel (CFS) steel framing members, usually track, to concrete, CMU or steel structural elements. “Power-actuated” is the broad category used to refer to fasteners which are driven directly through the CFS and into the substrate, using a powder, gas, compressed air or electro-mechanically driven tool. Efficient installation of framing systems is greatly enhanced by the use of PAF’s. For CFS-to-steel applications, the specification AISI S100 addresses all relevant limit states with equations and safety/ resistance factors. For CFS-to-concrete, limited guidance is provided but not all limit states are covered. This technical note will provide design guidance based on AISI S100, as well as installation and good detailing practice.

Tech Note 559: Design Considerations for Flexural and Lateral-Torsional Bracing
Summary: Load bearing cold-formed/light gauge steel (CFS/LGS) framed walls are typically designed for a combination of axial and lateral out-of-plane (flexural) loading. Under this loading condition, common C-section studs may be susceptible to local, torsional, flexural, torsional-flexural, lateral-torsional or distortional buckling. The response performance of the stud depends on a number of parameters most notably how it is supported along its length (including its ends), the relative magnitudes of the applied loads and the distribution of these loads. This Technical Note discusses the behavior of the typical wall stud and provides some practical considerations for design of torsional-flexural and lateral-torsional bracing. Recommendations and considerations suggested in this technical note are done in accordance with acceptable practices and existing design documents.

Tech Note F140-16: Welding Cold-Formed Steel
Summary: In cold-formed steel construction, welding is a viable connection method. Of the various forms of welding, arc welding is most commonly used to join both cold-formed steel members and hardware components. Prefabrication of roof trusses, panelization of walls, and hardware connections are all ideal applications where welding may be the preferred joining method. This Tech Note provides information on the applicable codes, processes, procedures, design considerations, fabrication and inspection.
