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 F300-09: Pneumatically Driven Pins for Wood Based Panel Attachment
Summary: Wood based panels for shear wall and horizontal diaphragms have traditionally been attached to cold-formed steel framing using tapping screws. To increase the speed of installation and to reduce the amount of labor used making these attachments, several companies supply pneumatic nailing systems. These products allow wood-based panels to be fastened to steel in a manner similar to which panels are nailed to wood framing. This Technical Note provides information on specifications, selection and field inspection of pneumatic drive pins.

Tech Note G104-14: Welded Box-Beam Flexure Design
Summary: A box-beam configuration may be used at openings in a floor or wall framing assembly. The AISI S100 contains design provisions for a built-up flexural members consisting of two C-sections back-to-back used as a flexural member. For built-up members to act as one unit (composite), the members must be connected together with sufficient fasteners and spacing. This Tech Note illustrates the extrapolation S100 Section D1.1 provisions to a box-beam configuration.

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 F502-18: Attachment of CFS Framing to Precast, Post-Tensioned, and Hollow-Core Concrete
Summary: Precast, prestressed, tilt-up, cast-in-place, and post-tensioned concrete are commonly used in podium construction. It is inevitable that the cold-formed steel design engineer will sooner or later be challenged with attaching cold-formed steel framing to podium construction. Towards this end, it is important for the designer to have a basic understanding of common precast concrete components and why connecting to them can be such a challenge. This Tech Note discusses the types of precast concrete components as well as the cold-formed steel anchorage options.

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.
