This Tech Note Updates and Replaces Tech Note B004-20
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 L101-23: Design of Cold-Formed Steel Sheet and Wood Structural Panel Sheathed Shear Walls for Wind and Seismic Forces
Summary: This Technical Note provides an overview of low seismic and wind-controlled steel sheet and wood structural panel sheathed cold-formed steel (CFS) framed shear wall designs. It is a digest of the AISI D113-19, Cold-Formed Steel Shear Wall Design Guide and presents a more basic overview of design considerations. Sample shear wall capacity and loading comparisons are provided. For detailed design examples, refer to the AISI D113-19.
Code references are limited to AISI S240-15, North American Standard for Cold-Formed Steel Structural Framing; more detailed references, including AISI S400-15, North American Standard for Seismic Design of Cold-Formed Steel Structural Systems for high seismic design requirements can be found in the AISI D113-19.

Tech Note FC101-22: Design of Cold-Formed Steel Rim Track
Summary: Cold-formed steel floor, roof, soffit, and ceiling joists are widely used in commercial applications. End of the joist rim track is an important component of many floor/roof/ceiling/soffit systems used to transfer load from the joist to another component of the structure. This Technical Note provides an overview of different rim track applications and how each is designed.

Tech Note W101-23: Common Design Issues for Deflection Track
This Tech Note Updates and Replaces Tech Note W101-09
Summary: When cold-formed steel studs are used on exterior walls between spandrel beams or floor slabs to create the exterior envelope of the building, a deflection track is often required at the top of the wall to allow for the roof or floor above to deflect without transferring axial load to the studs. This Technical Note explores two methods for deflection track usage. Additional design guidance is provided in CFSEI Tech Note W100, Single Slip Track.

Tech Note S100-24: Antiterrorism Design Requirements for Cold-Formed Steel Framing
This Tech Note Updates and Replaces Tech Note S100-24
Summary: Understanding and implementing antiterrorism requirements into cold-formed steel framing (CFS) design can be a daunting task for a design engineer. In recent years, the DoD Unified Facilities Criteria program has developed documents to help walk a designer through the process; however, considerable confusion still exists. CFS can be used throughout the building as exterior and/or interior walls, as well as floor and roof systems. However, the focus of this technical note is blast protection of building envelopes, specifically exterior walls. The applicability of UFC 4-010-01 to the design of the building envelope is discussed, and the static and dynamic design approaches for exterior walls are presented and worked out in a design example.

Tech Note W100-23: Single Slip Track Design
This Tech Note Updates and Replaces Tech Note W100-08a
Summary: The AISI S240, North American Standard for Cold-Formed Steel Structural Framing provides a design methodology for wall framing members installed in a deflection track at a head-of-wall condition. There had been previous methods for this analysis; most notably that permitted by the U. S. Army Corps of Engineers Technical Letter 1110-3-439, and the SSMA Technical Notes on Single- and Double- Slip Track Design. This document covers the most common types of slip track connections, how to handle general and specific issues with slip track construction and design, provides a design example, as well as tabulated information on allowable slip track loads.
