AISC Releases New Steel Specification
April 06, 2005 From American Institute of Steel Construction, Inc.
The American Institute of Steel Construction, Inc., announced today the pending release on June 15 of the 2005 Specification for Structural Steel Buildings. The new document is expected to form the basis for steel design in the 2006 International Building Code.
“In drafting the new Specification, AISC responded to the requests of the design community for a simple and easy-to-use document,” explained Louis F. Geschwindner, AISC’s vice president of engineering and research. Most importantly, the new document allows designers to use either ASD or LRFD load combinations. “Essentially, the new Specification combines both of the previously existing design methodologies but incorporates all of the recent advancements in structural design,” said Geschwindner.
In addition, the 2005 Specification integrates the provisions from the previously separate AISC specifications covering single angle members and hollow structural sections (HSS). The 2005 Specification also is fully coordinated with the 2005 AISC Seismic Provisions and the 2005 AISC Code of Standard Practice.
“Everyone who’s seen the draft documents agrees that it’s a simple-to-use Specification—even long-time ASD users,” said Charles J. Carter, AISC’s chief structural engineer. “As written, the 2005 AISC Specification is as detailed as possible, but its format can even be reduced to a much simplified set of requirements by considering only the applications steel designers will use regularly and by applying some conservative assumptions,” he explained. “To that end, AISC is developing two 5”-by-8” cards called Basic Design Values. The cards cover the typical applications of W-shapes, HSS, pipe, connections, and analysis requirements. All equations fit comfortably with ASD and LRFD. Information is presented in a way that makes sense to those who like to see equations in stress format, as well as to those who like to see them in strength format. Also, there isn’t an equation on the cards longer than the front half of my thumb!”
The Specification forms the basis for the new AISC Steel Construction Manual, which has an expected release date of fourth quarter 2005. The 2005 Manual also was designed for simpler use. One major change was a major expansion of design examples, which are being removed from the printed volume and instead being provided on an accompanying CD.
The new Specification and Manual is the latest phase in AISC’s drive to better meet the needs of the design community and construction industry. To help meet that goal, AISC has made all of its specifications available as free downloads from www.aisc.org. In addition, AISC offers free technical support via its Steel Solutions Center ([email protected] or 866.ask.aisc). AISC also has substantially reduced its membership rates for designers, contractors, code officials, and building inspectors and provides free electronic access to more than 10,000 pages of technical information to its members.
