Flexural Members Chapter E: These cold-formed steel framing standards are available as free downloads at www. Sheathing and discrete bracing.
Inthe manufacturing tolerance values were extended to the flange width and stiffening lip length. Leave a Comment Click here to cancel reply.
Permanent link to this article: Z212-07 newly developed chapter provides minimum requirements for quality control and quality assurance for material control and installation for cold-formed steel light-frame construction.
Additional explanatory language is also provided. Yu, Wiley-Interscience Back to top. Effective strip method model for steel-sheet sheathing. This appendix contains requirements for aisu determination of the rotational stiffness that structural sheathing provides to framing members to facilitate the design for distortional buckling.
From tothe AISI Committee on Framing Standards developed nine different framing standards to cover specific aspects of cold-formed steel framing.
The scope was selected to provide coverage of the high volume application of cold-formed steel in light-framed construction. ASTM C has historically stipulated manufacturing tolerances for cold-formed steel structural framing members.
Beneficial for the design engineer is a new Effective Strip Method that enables the calculation of the nominal in-plane shear wall strength for Type I shear walls Figure 2. The truss component structural performance load test and full-scale truss confirmatory test methods, previously ss212-07 in AISI Wisi, are provided in this appendix. Format defines design considerations. Therefore AISI extended its standards development activity to support the growing needs of the cold-formed steel framing industry.
The method assumes a sheathing strip carries the lateral load via tension field action. Also, for ease of use, S contains a section reference table between the S provisions and the previous provisions Table 2.
The document addresses the design iasi a C-shaped cross section as a flexural member and a compression member. The discrete braces are limited to not greater than 8 feet 2. Your message Submit Comment.
The ends of a built-up compression member are connected by a weld having a length not less than the maximum width of the member or by connectors spaced longitudinally not more than 4 diameters apart for a distance equal to 1.
This chapter contains design, manufacturing quality criteria, and installation requirements for cold-formed steel trusses as previously included in AISI S Connection design is limited to primarily a discussion of screw connections. Powered by WordPress and the Graphene Theme. Although the AISI Specification had gained acceptance and was in widespread use, there were a number of design issues that were not adequately addressed for this emerging market.
These applications include wall, floor and roof framing in a number of building types. This chapter provides installation requirements previously contained in the various framing standards.

But, why would AISI develop six discrete framing standards as opposed to one design manual? The commentary and explanatory language is identified by a vertical black line along the right margin.
Six of these standards addressed the aosi of structural elements, such as general provisions, wall studs, floor joists, trusses, headers, and shear walls. The simple reason is, it was easier to develop small single-topic documents versus a more comprehensive multi-topic document.
This new chapter lists applicable AISI test standards for cold-formed steel framing members, connections, and systems. This new standard includes design provisions for wall systems, floor and roof systems, lateral force-resisting systems, as well as truss and header assemblies. The exception applies where the built-up section is seated properly in a track, and the top and bottom end bearing detail of the studs consists of a steel or concrete support with adequate strength and stiffness to preclude relative end slip of the two built-up stud sections.
It outlines the s212–07, which is for design and installation of cold-formed steel framing of a floor and roof systems, b structural walls, c shear walls, strap braced walls, and diaphragms to resist in-plane lateral loads, and d trusses for load-carrying purposes in buildings. This a212-07 exception provides for a more economical built-up member, as is often used as a jamb stud or shear wall boundary member. This article focuses on AISI S which applies to cold-formed steel structural members subject to gravity loading, wind loading, and seismic loading, except when specific seismic detailing is required.
