Steel Industry Standardizes Terminology

May 04, 2005 From American Institute of Steel Construction, Inc.

A new document from the American Institute of Steel Construction (AISC) and the American Iron and Steel Institute (AISI) is designed to eliminate confusion among readers of technical documents related to steel. Standard Definitions for Use in the Design of Steel Structures is essentially a glossary of terms used in the standards produced by AISC and AISI, including the new Specification for Structural Steel Buildings, which will be available on June 15.

“Common engineering terms can have different meanings to different people,” explained Cindi Duncan, AISC’s Director of Specifications. “This document will provide standardized terms that will eliminate conflicting usage of common engineering terms, making the application of steel design standards easier for users.”

In addition to the new Specification, other documents utilizing the standardized terms include:

    • Specification for Structural Steel Buildings (ANSI/AISC 360)
    • Seismic Provisions for Structural Steel Buildings (ANSI/AISC 341)
    • Prequalified Connections for Special and Intermediate Moment Frames in Seismic Applications (ANSI/AISC 358)
    • Standard for Cold-Formed Steel Framing, 2004 Edition

The five pages of terms range from very common terms, such as “connection” (combination of structural elements and joints used to transmit forces between two or more members), to the more esoteric, such as “rational engineering analysis” (analysis based on theory that is appropriate for the situation, relevant test data if available, and sound engineering judgment).

Copies of the Standard Definitions for Use in the Design of Steel Structures can be downloaded at no charge by visiting: www.aisc.org/jointterminology.
