AISI Publishes Cold-Formed Steel Design Manual

WASHINGTON, D.C., June 10, 2009  – The American Iron and Steel Institute (AISI) announced today the publication of the 2008 edition of the Cold-Formed Steel Design Manual. The Manual supplements AISI S100-07, the 2007 edition of the North American Specification for the Design of Cold-Formed Steel Structural Members. It is available for purchase online at www.steel.org.

The material contained in the new manual was developed under the direction of AISI’s Committee on Specifications for the Design of Cold-Formed Steel Structural Members. It provides the latest design information for conformance with AISI S100-07, as well as new improvements and additions.

“This is one of the best documents that engineers, software developers and building officials can use to better understand the North American Specification and to correctly apply the design provisions,” Jay Larson, P.E., F. ASCE, Managing Director, Construction Technical Program, said. “The comprehensive design examples provide a step-by-step demonstration of how to use the provisions in the North American Specification. There are several tables and charts that also serve as design tools for engineers to perform cold-formed steel member design.”

The Cold-Formed Steel Design Manual consists of six parts:

  • Part I, Dimensions and Properties - Contains information on the availability and properties of steels referenced in the North American Specification (AISI S100), tables of section properties, and formulas and examples of calculations of section properties.
  • Part II, Beam Design - Contains tables and charts to aid in beam design and example problems.
  • Part III, Column Design - Contains tables to aid in column design and example problems.
  • Part IV, Connections - Contains tables to aid in connection design and example problems.
  • Part V, Supplementary Information - Contains a table of Specification cross-references to examples provided in the Design Manual, design procedures not included in the Specification, and additional information to assist users of cold-formed steel.
  • Part VI, Test Standards - Contains 14 American National Standards Institute (ANSI)-approved AISI test methods for cold-formed steel, a bibliography of other pertinent test methods, and an example problem.

In Parts I-IV, summaries explain the intent of the Specification provisions and provide essential design guidelines for users. Nine examples have been added to illustrate the new design provisions introduced in the Specification. All the test standards have been updated, and six new test standards have been added.

AISI’s codes and standards work is conducted under the Construction Market Council of the Steel Market Development Institute (SMDI), a business unit of AISI. The SMDI oversees the industry’s investment in advancing the case for steel in the marketplace as the preferred material of choice.

AISI serves as the voice of the North American steel industry in the public policy arena and plays a lead role in the development and application of new steels and steelmaking technology. AISI is comprised of 24 member companies, including integrated and electric furnace steelmakers, and 138 associate and affiliate members who are suppliers to or customers of the steel industry. AISI’s member companies represent approximately 75 percent of both U.S. and North American steel capacity. For more news about steel and its applications, visit www.smdisteel.org.
