The simple reason is, it was easier to develop small single-topic documents versus a more comprehensive multi-topic document. Additional explanatory language is also provided. The list of these standards, as well as other excellent design guides, are provided. However, AISI S now incorporates aisu exception for a built-up axial load bearing section comprised of two studs oriented back-to-back forming an I-shaped aksi.

This new standard includes design provisions for wall systems, floor and roof systems, lateral force-resisting systems, as well as truss and header assemblies.

This computational wisi is applicable for walls sheathed with steel sheet. 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.

Sheathing and discrete bracing. Inthe manufacturing tolerance values were extended to the flange width and stiffening lip length. 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. 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 s212-077 stud sections.

Format defines design considerations. 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.

Also, for ease of use, S contains a section reference table between the S provisions and the previous provisions Table 2. ASTM C has historically stipulated manufacturing tolerances for cold-formed steel structural framing members.

The document addresses the design for a C-shaped cross section as a flexural member and a compression member. For roof or floor diaphragms with a maximum aspect ratio of 4: Yu, Wiley-Interscience Back to top.

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. The chapter also includes:. The other standards addressed such topics as a code of standard practice, the definition of standard product, and prescriptive design for residential applications. Effective strip method model for steel-sheet sheathing.

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. The effective strip method is permitted to be used within the following range of parameters:. Six of these standards addressed the design of structural elements, such xisi general provisions, wall studs, floor joists, trusses, headers, aisii shear walls.

This chapter contains design, manufacturing quality criteria, and installation requirements for cold-formed steel trusses as previously included in AISI S The commentary and explanatory language is identified by a vertical black line along the right margin. 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.


This chapter provides installation requirements previously contained in the various framing standards. Print this Page Design Documents. This chapter contains design provisions for cold-formed steel framing members and assemblies, as previously included in AISI S, S, S, and S Although the AISI Specification had gained acceptance and was in widespread use, there were a number of design issues that were not adequately 2s12-07 for this emerging market.

The previous design standards limited their application to framing members having a maximum base steel thickness to mils 0. This new exception provides for a more economical built-up member, as is often used as a jamb stud or shear wall boundary member.

However, rather than add to the complexity of the AISI Specification, it was decided s212-70 a new family of standards should be developed. This has been an often asked question by framing design engineers. Your message Submit Comment.
