This has been an often asked question by framing design engineers. Sheathing and discrete bracing. Also, for ease of use, S s2200-07 a section reference table between the S provisions and the previous provisions Table s20-07.

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.

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 new chapter lists applicable AISI test standards for cold-formed steel framing members, connections, and systems. Leave a Comment Click here to cancel reply. w200-07

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 method provides an alternative approach to determine the shear wall strength, especially for those that are outside the limitations of the tested systems. The chapter also includes:.

The previous design standards limited their application to framing members having x200-07 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. First Name Last Name. This computational method is applicable for walls sheathed with steel sheet. 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 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 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. 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 s20-07 walls, and diaphragms to resist in-plane lateral loads, and d trusses for load-carrying purposes in buildings.

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. Aidi chapter contains design, manufacturing quality criteria, and installation requirements for cold-formed steel trusses as previously included in AISI S But, why would AISI develop six discrete framing standards as opposed to one design manual?

These cold-formed steel framing standards are available as free downloads at www. 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 s020-07 method historically used for steel deck diaphragms.

The effective strip method is permitted to be used within the following range of parameters:.

For roof or floor diaphragms with a maximum aspect ratio of 4: 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 method assumes a sheathing strip carries the lateral load via tension field action. The truss component structural performance load test and full-scale truss confirmatory test methods, previously included in AISI S, are provided in this appendix.


ASTM C has historically stipulated manufacturing tolerances for cold-formed steel structural framing members. This new standard includes design provisions for wall systems, floor and roof systems, lateral force-resisting systems, as well as truss and header assemblies. Format defines design considerations. Your message Submit Comment. The discrete braces are limited to not greater than 8 feet 2. Section reference table S and previous standard.

This chapter contains design provisions for cold-formed steel framing s2000-07 and assemblies, as previously included in AISI S, S, S, and S Effective strip method model for steel-sheet sheathing. Six of these standards addressed the design of structural elements, such as general provisions, wall studs, floor joists, trusses, headers, and shear walls.

Industry News

From tothe AISI Committee on Framing Standards developed nine different framing standards to cover specific aspects of cold-formed steel framing. This chapter provides installation requirements previously contained in the various framing standards. The simple reason is, it was easier to develop small single-topic documents versus a more comprehensive multi-topic document.

This limitation has been eliminated from AISI S; however, it should be remembered that mils is still the maximum thickness of standard products s200-70 the United States and 97 mils 0. The other standards addressed such topics as a code of standard practice, the definition of standard product, and prescriptive design for residential applications.
