This new exception provides for a more economical built-up member, as is often used as a jamb stud or shear wall boundary member. Your s2112-07 Submit Comment. The truss component structural performance load test and full-scale truss confirmatory test methods, previously included in AISI S, are provided in this appendix.
Flexural Members Chapter E: The effective strip method is permitted to be used within the following range of parameters:. The document addresses the design for a C-shaped cross section as a flexural member and a compression member. Connection design is limited to primarily a discussion of screw connections.
However, rather than add to the complexity of the AISI S212-70, it was decided that a new family of standards should be developed. Six of these standards addressed the design of structural elements, such as general provisions, wall studs, floor joists, trusses, headers, and shear walls. ASTM C has historically stipulated manufacturing tolerances for cold-formed steel structural framing members. This document aisl intended to serve only as an educational tool. This has been an often asked question by framing design engineers.
The list of these standards, as well as other excellent design guides, are provided. 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.
Format defines design considerations. 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 aidi standards addressed such topics as a code of standard practice, the definition of standard product, aizi prescriptive design s212-077 residential applications.
Also, for ease of use, S s22-07 a section reference table between the S provisions and the previous provisions Table 2. Leave a Comment S21207 here to cancel reply. The commentary and explanatory language is identified by a vertical black line along the right margin.
This new chapter lists applicable AISI test standards for cold-formed steel framing members, connections, and systems. These applications include wall, floor and roof framing in a number of building types. 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.
This chapter provides installation requirements previously contained in the various framing standards.
This computational method is applicable for walls sheathed with steel sheet. Additional explanatory language is also provided.
This method provides an alternative approach to determine the shear wall strength, especially for those that are outside iasi limitations of the tested systems. The chapter also includes:. This chapter contains design provisions for cold-formed steel framing members and assemblies, as previously included in AISI S, S, S, and S Sheathing and discrete bracing. The previous design standards limited their application to framing members having a maximum base steel thickness to mils 0.

Yu, Wiley-Interscience Back to top. 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. Print this Page Design Documents. Section reference table S and previous standard. S212–07 scope was selected to provide coverage of the high volume application of cold-formed steel in light-framed construction.
The method assumes a sheathing strip carries the lateral load via tension field action. These cold-formed steel framing standards are available as free downloads at www. This limitation has been eliminated from AISI S; however, it should be remembered alsi mils is still the maximum thickness of standard products in the United States and 97 mils 0.
Therefore AISI extended its standards development activity to support the growing needs of the cold-formed steel framing industry. For roof or floor diaphragms with a maximum aspect ratio of 4: Inthe manufacturing tolerance values were extended to the flange width and stiffening lip length.
Zisi link to this article: But, why would AISI develop six discrete framing standards as opposed to one design manual? 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.
