Summary: This Technical Note presents a discussion of both the design responsibilities and the need for coordination when integrating field-framed, i.e., stick-built, cold-formed steel (CFS) framing with a metal building system. Important potential coordination topics connection details and design concepts are highlighted.

Tech Note W600-21: Cold-Formed Steel Load-Bearing Wall Design
Summary: This Technical Note has been written to help cold-formed steel (CFS) engineers further their understanding of structural load-bearing CFS walls. Given the myriad of details required for such structures, the importance of proper design and analysis of load-bearing CFS members cannot be understated. This Technical Note will discuss the various design considerations that must be taken into consideration during the design phase of such structures.

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 F602-20: Screw Connections with Other Materials or Gaps Between the Plies
Summary: Screws are the most common connection type for connecting cold-formed steel members to one another. It is also common for gaps to be provided between members in the form of other materials such as gypsum or insulation, but unfortunately, the current standards do not provide clear direction for the design of screwed connections with gaps in the material. This Tech Note will summarize available test data and propose design guidance based on the available test data.

Tech Note B006-20: Introduction to Evaluation Services and Explanation of Evaluation Reports
Summary: Evaluation reports act as a bridge between authorities having jurisdiction (AHJs) and manufacturers in conveying specific information on building products and systems relative to compliance to codes and standards. When an evaluation report is made available and determined as supporting the product’s use in projects, approval of the code official should be solicited. After such approval is attained, the design and installation details given in the report need to be observed and the labeling of the actual product needs to match the description provided in the evaluation report.

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 G105-22: Compression Member Reinforcement
Summary: To modify the capacity of a compression member, e.g. wall stud or truss web, adding a reinforcement may result in a non-prismatic member. This Tech Note provides guidance to evaluate the strength of a non-prismatic compression member.

Tech Note B004-20: Introduction to Cold-Formed Steel Framing Standards
Summary: The AISI Committee on Framing Standards was established in 1998 with a mission to eliminate regulatory barriers and increase the reliability and cost competitiveness of cold-formed steel framing in residential and light commercial building construction through improved design and installation standards. This Tech Note summarizes the efforts and work products of the Committee.
