Tech Note B006-20: Introduction to Evaluation Services and Explanation of Evaluation Reports
$5.00
Summary: Evaluation reports act as a bridge between authorities having jurisdiction (AHJs) and manufacturers in conveying specific information on building products and systems relative to compliance to codes and standards. When an evaluation report is made available and determined as supporting the product’s use in projects, approval of the code official should be solicited. After such approval is attained, the design and installation details given in the report need to be observed and the labeling of the actual product needs to match the description provided in the evaluation report.
Disclaimer: Designs cited herein are not intended to preclude the use of other materials, assemblies, structures or designs when these other designs demonstrate equivalent performance for the intended use. CFSEI documents are not intended to exclude the use and implementation of any other design or construction technique.

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 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 B003-20: Introduction to Building Codes
Summary: The International Code Council develops a suite of building codes that are considered nationally to be the model codes for the building industry. Local jurisdictions adopt, and in some cases amend, the codes and they become the law of the jurisdiction for building design and construction. The adopted building codes are intended to provide minimum requirements to provide a safe building environment. Among other requirements, the code dictates the maximum allowable size of a building based on its intended use, materials used in construction, fire resistance rating of structural elements, and the presence of automatic sprinkler systems. The International Building Code establishes all design loads to be applied to the building or structure. The building code also relies on references to other standards and specifications to ensure the provisions reflect the current industry practice. For cold-formed steel framing, the IBC references the American Iron and Steel Institute’s suite of framing standards as the accepted design methods and procedures.

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 G000-08: Cold-Formed Steel Design Software
Summary: This Tech Note gives basic information about computer programs available for the design of cold-formed steel framed buildings, structures, and structural elements. It is not necessarily a comprehensive list, but is based on the best available information to the CFSEI at the time of publication. It is not intended to endorse or exclude any particular software program.

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.
