Tech Note B001-20: How Cold-Formed Steel Framing is Produced
Summary: Cold-formed steel seems like a fairly simple product when you are holding it in your hand, but as you can see, there are many production steps involving things like mining iron ore out of the ground, creating molten steel, furnaces above 2,000°F, reduction mills imparting forces in excess of 100,000 pounds per square inch, and hydrochloric acid cleaning baths before it even reaches the roll forming stage. This Tech Note has provided a basic outline of the processes involved in producing the products you work with daily, be it manufacturing, drafting, designing, engineering, installing or demolishing a building at the end of its life cycle.

Tech Note FC101-22: Design of Cold-Formed Steel Rim Track
Summary: Cold-formed steel floor, roof, soffit, and ceiling joists are widely used in commercial applications. End of the joist rim track is an important component of many floor/roof/ceiling/soffit systems used to transfer load from the joist to another component of the structure. This Technical Note provides an overview of different rim track applications and how each is designed.

Tech Note F501-11: Cold-Formed Steel Truss To Bearing Connections
Summary: This Technical Note is intended as general educational information and to highlight what the building designer should be aware of with regard to truss to bearing connections. Topics addressed include what loads due to wind truss to bearing connections may have to resist, who is ultimately responsible for truss to bearing connection design, general guidance on the design of truss to bearing connections, and an illustrative design example. Loads due to seismic forces are not addressed in this Technical Note.

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 S300-21: Coordinating Cold-Formed with Metal Buildings
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 B008-20: Basic C-Shaped Wall Stud Behavior
Summary: Although cold-formed steel framing shares some limit states with hot-rolled steel, cold-formed steel framing and specifically C-Shaped studs exhibit unique behaviors when subjected to various loading conditions. This Tech Note gives an overview of those unique behaviors that need to be considered when designing C-Shaped cold-formed steel members.

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.
