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. 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 aizi walls, and diaphragms to resist in-plane lateral loads, and d trusses for load-carrying purposes in buildings.

Inthe manufacturing tolerance values were extended to the flange width and stiffening lip length. The discrete braces are limited to s23-07 greater than 8 feet 2.

This aosi chapter lists applicable AISI test standards for cold-formed steel framing members, connections, and systems. This computational method is applicable for walls sheathed with steel sheet. Six of these standards addressed the design of structural elements, such as general provisions, wall studs, floor joists, trusses, headers, and shear walls. 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.


Format defines design considerations. The chapter also includes:. This new exception provides for a more economical built-up member, as is often used as a jamb stud or shear wall boundary 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.

But, why would AISI develop six discrete framing standards as opposed to one design manual? This chapter provides installation requirements previously contained in the various framing standards. 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 z213-07 diameters apart for a distance equal to 1. Effective strip method model e213-07 steel-sheet sheathing.

These cold-formed steel framing standards are available as free downloads at www. 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. 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 method assumes a sheathing strip carries the lateral load via tension field action. The simple reason is, it was easier to develop small single-topic documents versus a more comprehensive multi-topic document. The exception aiso 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.


This chapter contains design provisions for cold-formed steel framing members and assemblies, as previously included in AISI S, S, S, and Aiisi Section reference table S and previous standard.

For roof or floor diaphragms with a maximum aspect ratio of 4: Ss213-07, AISI S2133-07 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. Also, for ease of use, S contains a section reference table between the S provisions and the previous provisions Table 2. The previous design standards limited their application to framing members having a maximum base steel thickness to mils 0.

First Name Last Name. The other standards addressed such topics as a code of s2213-07 practice, the definition of standard product, and prescriptive design for residential applications.

This has been an often asked question by framing design engineers. The effective strip method is permitted to be used within the following range of parameters:.

S2213-07 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 s231-07 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.
