AISI-Specifications for the Design of Cold-Formed Steel Structural Members

Alternative Title

Research Report RP09-2

Abstract

The North American Standard for Cold-Formed Steel Framing - Lateral Design, AISI S213-07, provides design provisions for cold-formed steel framed shear walls with steel sheet sheathing. However, options are limited to 18-mil and 27-mil steel sheet sheathing. Phase 1 of this project was successfully completed and a final report, Steel Sheet Sheathing Options for Cold-Formed Steel Framed Shear Wall Assemblies Providing Shear Resistance, dated October 31, 2007 has been issued. The primary objective of Phase 1 was to add values to AISI S213 for 30-mil and 33-mil sheet steel shear walls with 2:1 and 4:1 aspect ratios and 6”, 4”, 3” and 2” fastener spacing at panel edges, and 27-mil sheet steel shear walls with 2:1 aspect ratio and 6”, 4”, 3” and 2” fastener spacing at panel edges. A further objective of Phase 1 was to verify the deflection equations in AISI S213 and develop new equations, if needed. An apparent discrepancy in the test results of Phase 1 when compared to previous work by other researchers necessita ed this Phase 2 project. The objective of Phase 2 was to verify and, if warranted, propose revised values in AISI S213 for 18-mil sheet steel shear walls with 2:1 aspect ratio and 6” fastener spacing at panel edges; and 27-mil sheet steel shear walls with 4:1 aspect ratio and 6”, 4”, 3” and 2” fastener spacing at panel edges. A further objective of Phase 2 was to determine special seismic detailing requirements, if any, needed to assure satisfactory performance of a 6’-wide sheet steel shear wall with a 2’-wide and a 4’-wide panel. Presented in this report are the findings from the monotonic and cyclic testing program that was conducted at the University of North Texas. It is anticipated that the results of this study will be incorporated in future standards developed by the AISI Committee on Framing Standards and design aids developed by the Cold-Formed Steel Engineers Institute.
