AISI S212-07 PDF

Shagul The list of these standards, as well as other excellent design guides, are provided. For curtain wall systems, the standard now permits the use of the bracing combination of sheathing attached to one side of the wall stud and discrete bracing for the other flange Figure 1. This new s includes design provisions for wall systems, floor and roof systems, lateral force-resisting systems, as well as truss and header assemblies. First Name Last Name. This new exception provides for a more economical built-up member, as is often used as a jamb stud or shear wall boundary member. The other standards addressed such topics as a code of standard practice, the definition of standard product, and prescriptive design for residential applications.

Connection design is limited to primarily a discussion of screw connections. The chapter also includes:. The commentary and aidi language is identified by a vertical black line along the right margin. Flexural Members Chapter E: This new exception provides for a more economical built-up member, as is often used as a jamb stud or shear wall boundary member.

For curtain wall systems, the standard now permits the use of the bracing combination of sheathing attached to qisi side of the wall stud and discrete bracing for the other flange Figure 1. Therefore AISI extended its standards development activity to support the growing needs of the cold-formed steel framing industry. Leave a Comment Click here to cancel reply. Your message Submit Comment. The document addresses the design for a C-shaped cross section as a flexural member and a compression member.

However, rather than add to the complexity of the AISI Specification, it was decided that a new family alsi standards should be developed. For roof or floor diaphragms with a maximum aspect ratio of 4: These cold-formed steel framing standards are available as free downloads at www.

Section reference table S and previous standard. Print this Page Design Documents. Also, for ease of use, S contains s section reference table between the S provisions and the previous provisions Table 2. 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.

This chapter contains design, manufacturing quality criteria, and installation requirements for cold-formed steel trusses as previously included in AISI S This article focuses on AISI S which alsi to cold-formed steel structural members subject to gravity loading, wind loading, and seismic loading, except when specific seismic detailing is required.

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. This chapter contains design provisions for cold-formed steel framing members and assemblies, as previously included in AISI S, S, S, and S The other standards addressed such topics as a code of standard practice, the definition of standard product, and prescriptive design aidi residential applications.

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 x a distance equal s 1.

Powered by WordPress and the Graphene Theme. This newly developed chapter provides minimum requirements for quality control and quality assurance for material control and installation for cold-formed steel light-frame construction.

The simple reason is, 2s was easier to develop small single-topic documents versus a more comprehensive multi-topic document. Additional explanatory language is also provided. This has been an often asked question by framing design engineers. Inthe manufacturing s values were extended to the flange width and stiffening lip length.

The use of ASTM E results in higher nominal shear strength values as compared with the cantilever test method historically used for steel deck diaphragms. But, why would AISI develop six discrete framing standards as opposed to one design manual? These applications include wall, floor and roof framing in a number of building types. This document is intended to serve only as an educational tool. Iasi exception applies where the built-up section is seated properly in a track, 2s 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.

Format defines design considerations. The list of these standards, as well as other excellent design guides, are provided. Aaisi and discrete bracing. Yu, Wiley-Interscience Back to top. It outlines the scope, 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.

Design Documents This chapter provides installation requirements previously contained in the various framing standards. ASTM C has historically stipulated manufacturing tolerances for cold-formed steel structural framing members.

The method assumes a sheathing strip carries the lateral load via tension field action. From tothe AISI Committee on Framing Standards developed nine different framing standards to cover specific aspects of cold-formed steel framing. The truss component structural performance load test and full-scale truss confirmatory test methods, previously included in AISI S, are aiai in this appendix.

Effective strip method model for steel-sheet sheathing. This appendix contains requirements for the determination of the rotational stiffness that structural sheathing provides to framing members to facilitate the design for distortional buckling.
