Tech Note W105-21: Design of Nonstructural Members
Summary: The AISI S220, North American Standard for Cold-Formed Steel Nonstructural Framing was developed in 2011 to help clearly delineate and eliminate confusion between the requirements for cold-formed steel structural members and nonstructural members. This Technical Note is intended as an introduction to this standard and as an illustrative guide for applying the provisions to the design of nonstructural members.
This Technical Note updates and replaces CFSEI Technical Note W105-13
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 W106-16: Design for Splicing of Cold-Formed Steel Wall Studs
Summary: This Technical Note discusses design methods for the splicing of two cold-formed steel studs in a curtain wall or interior nonstructural wall condition. Splicing of wall studs may be required in the field to extend studs to the required length.
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 W200-09: Header Design
Summary: The Standard for Cold-Formed Steel Framing AISI S212-07, Header Design is aimed at giving design professionals the tools they need to design headers over door and window openings in buildings. AISI S212-07, Header reflects the appropriate design procedures for back-to-back headers, box headers, and L-headers subject to gravity loads
or wind uplift loads. This Technical Note provides additional recommendations and design examples intended to augment AISI S212-07, Header.
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 W400-16: Mechanical Bridging and Bridging Anchorage of Axially Loaded Cold-Formed Steel Studs
Summary: The purpose of this Technical Note is to provide a clear understanding of the design requirements and methods to laterally brace (bridge) axially loaded cold-formed steel stud walls.
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 W500-12: Construction Bracing for Walls
Summary: Temporary construction bracing may be necessary to assure structural stability of wall assemblies. This temporary bracing is required to resist loads imposed on a structure during construction. The purpose of this Technical Note is to provide design guidance.
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 W600-21: Cold-Formed Steel Load-Bearing Wall Design
Summary: This Technical Note has been written to help cold-formed steel (CFS) engineers further their understanding of structural load-bearing CFS walls. Given the myriad of details required for such structures, the importance of proper design and analysis of load-bearing CFS members cannot be understated. This Technical Note will discuss the various design considerations that must be taken into consideration during the design phase of such structures.
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.
