Tech Note L000-08: Changes from the 1997 UBC to the 2006 IBC for Lateral Design with Cold-Formed Steel Framing
$5.00
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 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 T202-20: Thermal Energy Transfer of Cold-Formed Steel Framing
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 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.

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.
