PREFACE
{to be revised}
As have all AISC Specifications, this Specification has been based upon past
successful usage, advances in the state of knowledge, and changes in design
practice. This Specification has been developed as a consensus document to provide
a uniform practice in the design of steel-framed buildings and other structures. The
intention is to provide design criteria for routine use and not to provide specific
criteria for infrequently encountered problems, which occur in the full range of
structural design.
This Specification is the result of the consensus deliberations of a committee of
structural engineers with wide experience and high professional standing,
representing a wide geographical distribution throughout the U.S. The committee
includes approximately equal numbers of engineers in private practice and code
agencies, engineers involved in research and teaching, and engineers employed by
steel fabricating and producing companies. The contributions and assistance of
more than 50 additional professional volunteers working in 15 task committees are
also hereby acknowledged.
The Symbols, Glossary, and Appendices to this Specification are an integral part of
the Specification. User Notes and a non-mandatory Commentary has been prepared
to provide background for the Specification provisions and the user is encouraged
to consult it.

The reader is cautioned that professional judgment must be exercised when data or
recommendations in the Specification are applied, as described more fully in the
disclaimer notice preceding this Preface.

17 A1. SCOPE
18
19 The Specification for Structural Steel Buildings hereafter referred to as the
20 Specification, shall apply to the design of the structural steel system, where
21 the steel elements are enumerated in the AISC Code of Standard Practice for
22 Steel Buildings and Bridges Section 2.1. As used in this Specification, the
23 term structural steel refers to the steel elements of the structural steel frame
24 essential to the support of the applied loads.
25
26 This Specification includes the list of symbols, the glossary, Chapters A
27 through M and Appendices 1 through 7. The commentary and the user notes
28 interspersed throughout are not part of this specification.
29
30 U ser Note: User notes are intended to provide concise and practical guidance
31 in the application of the provisions.
32
33 This Specification sets forth criteria for the design of structural steel buildings
34 and other structures. Where conditions are not covered by the Specification,
35 designs are permitted to be based on tests or analysis, subject to the approval
36 of the authority having jurisdiction. Alternate methods of analysis and design
37 shall be permitted, provided such alternate methods or criteria are acceptable
38 to the authority having jurisdiction.
39
40 User Note: For the design of structural members, other than HSS, that are
41 cold-formed to shapes with elements not more than 1-in. (25 mm) in
42 thickness, the provisions in the AISI North American Specification for the
43 Design of Cold-Formed Steel Structural Members is recommended.
44
45 1. Low-Seismic Applications
46
47 When the seismic response modification coefficient R (as specified in the
48 Applicable Building Code) is taken equal to or less than 3, the design,
49 fabrication, and erection of structural-steel-framed buildings shall comply
50 with this Specification.
2
51
52 2. High-Seismic Applications
53
54 When the seismic response modification coefficient R (as specified in the
55 Applicable Building Code) is taken greater than 3, the design, fabrication and
56 erection of structural-steel-framed buildings shall comply with the
57 requirements in the Seismic Provisions for Structural Steel Buildings
58 (ANSI/AISC 341).
59
60 3. Nuclear Applications
61
62 The design of nuclear structures shall comply with the requirements of the
63 Specification for the Design, Fabrication, and Erection of Steel Safety-
64 Related Structures in Nuclear Facilities (ANSI/AISC N690) including
65 Supplement No. 2 or the Load and Resistance Factor Design Specification
66 for Steel Safety-Related Structures for Nuclear Facilities (ANSI/AISC
67 N690L).
