specification and commentary (PDF)
copyright permission letter

This specification provides the generally applicable requirements for the design and construction of structural steel buildings and other structures. The 2010 edition of the AISC Specification and Commentary supersedes and is an update of the 2005 edition. Both LRFD and ASD methods of design are incorporated. Dual-units format provides for both U.S. customary and S.I. units.

2016 Prequalified Connections for Special and Intermediate Steel Moment Frames for Seismic Applications (ANSI/AISC 358-16)

This standard has been developed by the AISC Connection Prequalification Review Panel in accordance with Chapter K of the Seismic Provisions for Structural Steel Buildings (ANSI/AISC 341-16). The connections have been prequalified for use in special and intermediate steel moment frames without the need for additional testing.

The standard addresses nine moment connections:

*These connection chapters discuss the possibility that implementation of this standard may require use of subject matter covered by patent rights. The patent holders have filed statements of willingness to grant a license under these rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to obtain such a license. 

2012 Specification for Safety-Related Steel Structures for Nuclear Facilities including Supplement No. 1 (ANSI/AISC N690-12 and N690s1-15)


This AISC standard, Specification for Safety-Related Steel Structures for Nuclear Facilities (ANSI/AISC N690-12), dated January 31, 2012, includes both the load and resistance factor design and allowable strength design methods of design, and is a supplement to the AISC 2010 Specification for Structural Steel Buildings. This document incorporates Supplement No. 1 dated August 11, 2015, which consists of a new Appendix on steel-plate composite walls and associated revisions. ANSI/AISC N690-12, in conjunction with ANSI/AISC N690s1-15, applies to the design of safety-related steel structures and steel elements in nuclear facilities and replaces ANSI/AISC N690-06. It has been approved by the AISC Committee on Specifications and it is ANSI-accredited.

2014 RCSC Specification for Structural joints Using High-Strength Bolts


This specification covers the design of bolted joints and the installation and inspection of fastener assemblies in structural steel connections. The document is maintained by the Research Council on Structural Connections (RCSC) with the participation of AISC.
