Floor Systems Design Manual: It is available for free download at http: AISI is comprised of 19 member companies, including integrated and electric furnace steelmakers, and approximately associate members who are suppliers to or customers of the steel industry.

Matsen was a widely respected structural engineer for more than 30 years and the founder and principal of Matsen Ford Design Associates, Inc. He is credited with helping to pioneer and expand the use of cold-formed steel framing in structural and nonstructural applications.

Thus, the stud pack is not engineered but, in fact, is simply assembled to provide an equal number of studs as if the opening did not occur. An often employed assumption by inexperienced cold-formed steel design s121 is that each stud in a stud pack has the same tributary area as a typical wall stud.

AISI Publishes S, North American Standard for Cold-Formed Steel Structural Framing

AISI S integrates the following AISI standards into one document for easy reference, and thus supersedes all previous editions of these standards: Leave a Reply Cancel reply Your email address will not be published.

It applies to the design and installation of structural members and connections utilized in s121 steel light-frame construction applications, including floor and roof systems, structural walls, shear aissi, strap braced walls and diaphragms to resist in-plane lateral loads, and trusses for load-carrying purposes.

What this assumption consists of is adding studs to the stud pack equal to the number of studs displaced by an opening. Close Explore the durability and resiliency of cold-formed steel framing when confronted with fire, cold weather, s2211, and flooding. AISI S integrates the following AISI standards into one document for easy reference, and thus supersedes all previous editions of these standards:.

Built-up cold-formed steel compression members are commonly used as shear wall chord members, and at openings of doors and windows stud packs to resist the additional load transferred from an opening header. Read Full Article Hide Comments.


A new location for truss test methods, which were moved from Section E7 to Appendix 2. Making this assumption can lead d211 a suspect load path or an uneconomical, design as any synergy of the individual stud pack members is not accounted for in the design.

Today there are various assumptions employed when designing the stud packs.

AISI serves as the voice of the North American steel industry in the public policy arena and advances aaisi case for steel in the marketplace as the preferred material of choice. Your email address will not be published.
