Tech Note G501-25: Evaluation and Remediation of Cold-Formed Steel Members and Connections
$5.00
Summary: The content of this Tech Note is based on inquiries obtained from the CFSEI Ask an Expert hotline https://www.cfsei.org/ask-cfs-expert.
This Tech Note will provide thoughts regarding potential methodology for remediation of cold-formed steel structural members. Remediation issues may be the result of on-site construction practices such as cutting large holes in web, cutting random holes in webs, notching, or coping of the flange of the section or improper installation of the self-drilling screws.

Tech Note T100-12: Fire Assemblies of Cold-Formed Steel Construction
Summary: Cold-formed steel has been widely used in commercial buildings, especially in non-load bearing (partitions) and curtain wall applications. Cold-formed steel sections are increasingly used as primary structural members, such as beams and columns, or as load-bearing walls or partitions in commercial and residential construction. In most cases, these members are required to be fire resistant where they are part of a compartment’s wall or floor, or where they support other floors. The purpose of this Tech Note is to provide the user with a comprehensive list of resources summarizing available tested fire rated steel assemblies, building code requirements, test methods and applicable
references.

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 B010-21: Introduction to AISI S202, Code of Standard Practice for Cold-Formed Steel Structural Framing
Summary: Understanding the responsibilities of the different parties involved in a cold-formed steel framing project can be confusing. This Technical Note is an introduction to AISI S202, Code of Standard Practice for Cold-Formed Steel Structural Framing published by the American Iron and Steel Institute (AISI).

Tech Note G801-13: ASTM A1003 – No Cause for Rejection
Summary: Building codes and design standards that reference ASTM International (ASTM) A1003 standard for cold-formed steel framing products have the potential to cause confusion and project delays for those who are unfamiliar with the requirements of this new material standard. This Technical Note, first published in 2008, provides a comparison of the requirements of A1003 with the more familiar standards traditionally used for cold-formed steel framing products, and demonstrates that steel ordered or furnished to the old standards should be no cause for rejection. The 2013 revision references a change to the requirements of ASTM A1003 regarding material thickness when ordering or supplying steel sheet.

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 L000-08: Changes from the 1997 UBC to the 2006 IBC for Lateral Design with Cold-Formed Steel Framing
Summary: The intent of this document is to highlight the changes to the cold-formed steel framing lateral design provisions in the 2006 International Building Code, which has adopted the AISI 2004 Standard for Cold-Formed Steel Framing – Lateral Design, in comparison to the cold-formed steel framing lateral provisions in the 1997 Uniform Building Code.

Tech Note F102-21: Screw Fastener Selection For Cold-Formed Steel Frame Construction
This Technical Note updates and replaces CFSEI Tech Note F102-11
Summary: Specifying the proper fastener is necessary to assure the proper performance of the connections used in cold-formed steel construction. Cold-formed steel connections primarily utilize externally threaded fasteners, so embedment is not the controlling parameter. Instead, the design of the fastener along with the thickness of the steel govern the value of the connection. This Tech Note provides basic information for determining the appropriate screw type for various applications.
