This limitation has been eliminated from AISI S; however, it should be remembered that mils is still the maximum thickness of standard products in the United States and 97 mils 0. This has been an often asked question by framing design engineers. Permanent link to this article: The simple reason is, e212-07 was easier to develop small single-topic documents versus a more comprehensive multi-topic document.

Effective s212–07 method model for steel-sheet sheathing. 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.

The list of these standards, as well as other excellent design guides, are provided. 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 provisions for cold-formed steel framing members and assemblies, as previously included in AISI S, S, S, and S First Name Last Name.

These applications include wall, floor and roof framing in a number of building types. The scope was selected to provide coverage of the high volume application of cold-formed steel in light-framed construction.

Yu, Wiley-Interscience Back to top. 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 document is intended to serve only as an educational tool. The truss component structural aii load s21-07 and full-scale truss confirmatory test methods, previously included in AISI S, are provided in this appendix. Additional explanatory language is also provided.


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. The s2212-07 of ASTM E results in higher nominal shear strength aisii as compared with the cantilever test method historically used for steel deck diaphragms.

This new standard includes design provisions for wall systems, floor and roof systems, lateral s212-0 systems, as well as truss and header assemblies. Flexural Members Chapter E: Print this Page Design Documents. Powered by WordPress and the Graphene Theme. 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 effective strip method is permitted to be used within the following range of parameters:.

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 previous design standards limited their application d212-07 framing members having a maximum base steel thickness to mils 0. Therefore AISI extended its standards development activity to support the growing needs of the cold-formed steel framing industry.

The discrete braces are limited to not greater than 8 feet 2. This computational method is applicable for walls sheathed with steel sheet. Sheathing and discrete bracing. The method assumes a sheathing strip carries the lateral load via tension field action.

Design Documents

This method provides an alternative approach to determine the shear wall strength, especially for those that are outside the limitations of the tested systems. The document addresses the design e212-07 a C-shaped cross section as a flexural member and a compression member.

This chapter contains design, manufacturing quality criteria, and installation requirements for cold-formed steel trusses as previously included in AISI S The other standards addressed such topics as a code of standard practice, the definition of standard product, and prescriptive design for residential applications.


Six of these standards addressed the design of structural elements, such as general provisions, wall studs, floor joists, trusses, headers, and shear walls. The chapter also includes:. Also, for ease of use, S contains a section reference table between the S provisions and the previous provisions Table 2.

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. Inthe manufacturing tolerance values were extended to the flange width and stiffening lip length. From tothe AISI Committee on Framing Standards developed nine different framing standards to cover specific aspects of cold-formed steel framing.

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. However, AISI S now incorporates an exception for a built-up axial load bearing section comprised of two studs oriented back-to-back forming an I-shaped cross-section.

Section reference table S and previous standard.

But, why would AISI develop six discrete framing standards as opposed to one design manual? However, rather than add to the complexity of the AISI Specification, it was decided that a new family of standards should be developed.

These cold-formed steel framing standards are available as free downloads zisi www. Connection design is limited to primarily a discussion of screw connections. For roof or floor diaphragms with a maximum aspect ratio of 4: 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.
