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 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.

Tech Note G102-09: Designing Cold-Formed Steel using the Direct Strength Method
Summary: The Direct Strength Method is an entirely new design method for cold-formed steel. The Direct Strength Method requires no effective width calculations, eliminates tedious iterations to determine section properties, properly includes interaction effects between elements of the cross-section such as the flange and the web, and opens up the potential to create new sections as it is applicable to nearly any shape that can be formed from cold-formed steel, as opposed to just C, Z and hat shapes. The Direct Strength Method was first adopted in 2004 as Appendix 1 to the North American Specification for the Design of Cold-Formed Steel Structural Members, and the most recent version can be found in the recently published AISI-S100-07. This CFSEI Technical Note introduces the Direct Strength Method and details some of the features of a recently published AISI Design Guide for this Method. The intent of this Tech Note and the Guide is to provide engineers with practical guidance in the application of this new design method.

Tech Note G103-11a: Tabulated Local And Distortional Elastic Buckling Solutions For Standard Shapes
Summary: This note provides elastic buckling moments and forces for local and distortional buckling of typical standard sections such as those in the AISI S201 Standard for Cold-Formed Steel Framing—Product Data and the Steel Stud Manufacturers Association (SSMA) Product Technical Information Catalog. These tabulated values allow designers to quickly examine and evaluate the use of the direct strength method (DSM) for design. Note that basic information on DSM is discussed in CFSEI Technical Note G102.

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 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.

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.
