The 1996 AISI Specification

The first edition of the AISI specification was adopted in 1946. Thus, the new specification represents fifty years of progress in the formal structural application of cold-formed steel. The continued efforts of the Committee on Specifications and the sponsorship of the American Iron and Steel Institute have made this fifty years of progress in cold-formed steel a reality. The new specification combines ASD and LRFD provisions in a single document. This affords the design engineer the opportunity to become familiar with both methods and facilitates the use of whichever method is preferred. In addition, the new specification includes a number of new or revised provisions based on the results of continuing research

The 1999 Supplement to the AISI Design Specification

The AISI Committee on Specifications for Cold-Formed Steel recently developed Supplement No. 1 to the 1996 Specification for the Design of Cold-Formed Steel Structural Members. The Supplement reflects new information developed through research projects, brings provisions in agreement with other specifications where appropriate, and also provides certain clarifications and corrections. The Supplement and the Specification have both been recently accepted as ANSI standards. The present paper reviews the major items included in the Supplement. The Committee continues to sponsor research projects aimed at developing a better understanding of particular areas of cold-formed steel behavior and more comprehensive design rules. Projects currently underway or recently completed are listed. As a result of a collaborative effort with representatives from Canada and Mexico, it is anticipated that the next edition of the specification will be referred to as the AISI North American Specification for the Design of Cold-Formed Steel Members

North American Specification for Design of Cold-Formed Steel

For over fifty years, the American Iron and Steel Institute has published the widely used Specification for the Design of Cold-Fom1ed Steel Structural Members. Recently, as a result of collaborative efforts with representatives of Canada and Mexico, the AISI Specification was expanded into a new document for use in all three countries. Now known as the North American Specification for the Design of Cold-Formed Steel Structural Members, the new edition supersedes the previous AISI Specification and the Canadian Sl36 Standard. This paper reviews the differences between the previous AISI Specification and the new North American Specification. The basic core document consists of Chapters A through G, while country specific issues are addressed in three separate appendices. The appendices include items of a broad nature, such as provisions for the design method to be used, the reference source for loads and load combinations, and other references that are country specific. The appendices also include country specific technical provisions where full agreement between the three countries was not reached. Efforts will be made to minimize these differences in future editions
