A new American Institute of Steel Construction, Inc. (AISC) specification, Load and Resistance Factor Design of Safety-Related Steel Structures for Nuclear Facilities (ANSI/AISC N690L-03), is now available for free downloading from www.aisc.org/freedownloads.
This is the first version of this document based on the load and resistance factor design (LRFD) method. It has been approved by the AISC Committee on Specifications and it is ANSI-accredited. The allowable stress design (ASD) version (ANSI/AISC N690-94) has already been available, along with a Supplement dated April 15, 2002.
There are plans to produce a “unified” version, similar in format to the 2005 AISC Specification for Structural Steel Buildings, by 2006. The unified version will allow the designer to use either ASD or LRFD methods of design.
