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 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 truss component structural performance load test and full-scale truss confirmatory test methods, previously included in AISI S, are provided in this appendix. The method assumes a sheathing strip carries the lateral load via tension field action. This article focuses on AISI S which applies to cold-formed steel structural members subject aisj gravity loading, wind loading, and seismic loading, except when specific seismic detailing is required.

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 effective strip method is permitted to be used within the following range of parameters:. The other standards addressed such topics as a code of standard practice, the definition of standard product, and prescriptive design for residential applications.

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 computational method is applicable for walls sheathed with steel sheet. This chapter contains design provisions for cold-formed steel framing members and assemblies, as previously included in AISI S, S, S, and S Format defines design considerations.

This new chapter lists applicable AISI test standards for cold-formed steel framing members, connections, and systems. This new standard includes design provisions for wall systems, floor and roof systems, lateral force-resisting systems, as well as truss and header assemblies.

ASTM C has historically stipulated manufacturing tolerances for cold-formed steel structural framing members. First Name Last Name. Sheathing and discrete bracing. This chapter provides installation requirements previously contained in the various framing standards. Zisi chapter contains design, manufacturing quality criteria, and installation requirements for cold-formed steel trusses as previously included in AISI S 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.

The simple reason is, it was xisi to develop small single-topic documents versus a more comprehensive multi-topic document. But, why would AISI develop six discrete framing standards as opposed to one design manual?


From tothe AISI Committee on Framing Standards developed nine different framing standards to cover specific aspects of cold-formed steel framing.

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.

Section reference table S and previous standard. The previous design standards limited their application to framing members having a maximum base steel thickness to mils 0.

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. The chapter also includes:. The discrete braces are limited to not greater than 8 feet 2.

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. 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.
