First Name Last Name. The scope was selected to provide coverage of the high volume application of cold-formed steel in light-framed construction.

The effective strip method is permitted to be used within the following range of parameters:. These applications include wall, floor and roof framing in a number of building types. Powered by WordPress and the Graphene Theme. This new exception provides for a aosi economical built-up member, aiwi is often used as a jamb stud or shear wall boundary member. Yu, Wiley-Interscience Back to top. 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.

ASTM C has historically stipulated manufacturing tolerances for cold-formed steel structural framing members. Flexural Members Chapter E: Print this Page 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 list of these standards, as well as other excellent design guides, are provided.

The truss component structural performance load test and full-scale truss confirmatory test methods, previously included in AISI S, are provided in this appendix. Sheathing and discrete bracing. This appendix contains requirements ss212-07 the determination of the rotational stiffness that structural sheathing provides to framing members to facilitate the design for distortional buckling.

The previous design standards limited their application to framing members having a maximum base steel thickness to mils 0.

This chapter contains design provisions for cold-formed steel framing members and assemblies, as previously included in AISI S, S, S, and S This has been an often asked question by framing design engineers. Inthe manufacturing tolerance 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.

From tothe Ajsi Committee on Framing Standards developed nine different framing standards to cover specific aspects of cold-formed steel framing. Format defines design considerations. Therefore AISI extended its standards development activity to support the growing needs of the cold-formed steel framing industry.

This chapter contains design, manufacturing quality criteria, and installation requirements for cold-formed ss212-07 trusses as previously included in AISI S This document is intended to serve only as an educational tool.

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. But, why would AISI develop six discrete framing standards as opposed to one design manual?

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.

Also, for ease of use, S contains a section reference table between the S provisions and the previous provisions Table 2. Effective strip method model for steel-sheet sheathing. However, rather than add to the complexity of the AISI Specification, it was decided that a new family of standards should be developed. The document addresses the design for a C-shaped cross section as a flexural member and a compression member.

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. 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.

This computational method is applicable for walls sheathed with steel sheet. Additional explanatory language is also provided.

S22-07 method assumes a sheathing strip carries the lateral load via tension field action. 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.

For roof or floor diaphragms with a maximum aspect ratio of 4: The commentary and explanatory language is identified by a vertical black line along the right margin. Beneficial for the design e212-07 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 simple reason is, it was easier to develop small single-topic documents versus a more comprehensive multi-topic document. These cold-formed steel framing standards are s2112-07 as free downloads at www. This chapter provides installation requirements previously contained in the various framing standards.

Six of these standards addressed the design of structural elements, such as general s122-07, wall studs, zisi joists, trusses, headers, and shear walls. 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. 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.

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 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.
