Tech Note G100-23: Using Chapter F of the North American Specification for the Design of CFS Structural Members
$5.00
This Tech Note Updates and Replaces Tech Note G100-07
Summary: The North American Specification for the Design of Cold-Formed Steel Structural Members is intended for use throughout the U.S., Canada and Mexico and was developed by the American Iron and Steel Institute, Canadian Standards Association, and CANACERO in Mexico. The Specification provides procedures for the design of load bearing cold-formed steel members in buildings and certain other applications.

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 W103-23: Design of By-Pass Slip Connectors in Cold-Formed Steel Construction
This Tech Note Updates and Replaces Tech Note W103-11
Summary: A curtain wall can be defined as a non-vertically loaded exterior wall (aside from self weight) supported by the primary structural frame of the building. When it comes to cold-formed steel framing, this definition can encompass a great many possible assemblies and applications. This Tech Note discusses the various structural elements of a curtain wall system and introduces the subjects of Design Loads and Framing Analysis.

Archived with cover page Nov. 2011
Summary: This note was archived November, 2011. The author has developed ASD design tables using an analytical method for wood framing based on the provisions of the 1991 edition of the AFPA National Design Specification for Wood Construction. Additional research is needed to bring the data in line with current codes and standards. The data below is from commentary section D2.1 of American Iron and Steel Institute AISI 213, Standard for Cold-Formed Steel Framing – Lateral Design.

Tech Note F701-23: Evaluation of Screw Strength
This Tech Note Updates and Replaces Tech Note J100-11
Summary: The design provisions for screw connections contained in the AISI S100, North American Specification for the Design of Cold-Formed Steel Structural Members contains specific limit states equations that pertain to the design strength of the connecting elements, i.e., sheets. In addition to sheet related design limit states, AISI S100 also provides design provisions for the screw when subjected to either pure shear or pure tension. However, the screw design provisions require that the screw capacity be defined by tests. In the absence of test data, the design engineer is at a loss for evaluating the strength of the screw. This Tech Note provides design guidance for the evaluation of the screw when subjected to pure shear, pure tension and combined shear and tension.
