Tech Note T202-20: Thermal Energy Transfer of Cold-Formed Steel Framing
$5.00
Summary: While the concepts of energy conservation and efficiency are not new, the demand for sustainable building is at an all-time high. Energy efficiency, and more specifically thermal energy transfer in steel stud construction, presents the construction team with a clear opportunity for reduction in thermal bridging. Advanced analysis of building thermal simulation through scientific thermal modeling programs illustrates that the construction team has the ability to significantly reduce thermal transfer. Use of cold-formed steel framing with a reduced thermal bridging area, in combination with increased spacing of the framing system provides, among other benefits, a significant and positive impact on thermal performance.

Tech Note G200-21: Chase the Loads: Load Path Considerations for Cold-Formed Steel Light-Frame Construction
This Technical Note updates and replaces CFSEI Technical Note G200-15
Summary: Engineering students are admonished to “chase the loads” in their structural analysis and design courses. A “load path” is the direction in which each consecutive load will pass through framing members and the connected members of a framing assembly. The load path sequence begins at the point of load application, both vertical (gravity, wind uplift or seismic vertical) and lateral, on the structure and works all the way down to the footing or foundation system, ultimately transferring the load of the structure to the foundation. This Tech Note provides insight into the load path considerations for cold-formed steel framing.

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 F101-12: Screws for Cold-Formed Steel-To-Wood and Wood-To-Cold-Formed Steel Attachments
Summary: Screws are often used to attach cold-formed steel (CFS) framing to wood members or wood structural panel decking to CFS joists or rafters. The AISI North American Specification for the Design of Cold-Formed Steel Structural Members (AISI S100) provides design equations for screw connection capacity for CFS members. The National Design Specification for Wood Construction (NDS) provides design equations for fastener/connection capacity (nails, wood screws, bolts, etc.) in wood members. The Engineered Wood Association (APA) and the building codes offer several resources for determining the capacity of screw connections attaching wood sheathing. This Tech Note reviews these resources and discusses design and detailing of these fastener connections.

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.
