PREFACE
(This Preface is not part of ANSI/AISC 360-10, Specification for Structural Steel Buildings,
but is included for informational purposes only.)
This Specification is based upon past successful usage, advances in the state of knowledge,
and changes in design practice. The 2010 American Institute of Steel Construction’s
Specification for Structural Steel Buildings provides an integrated treatment of allowable
stress design (ASD) and load and resistance factor design (LRFD), and replaces earlier
Specifications. As indicated in Chapter B of the Specification, designs can be made accord-
ing to either ASD or LRFD provisions.
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 pro-
vide 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 geo-
graphical distribution throughout the United States. 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 compa-
nies. The contributions and assistance of more than 50 additional professional volunteers
working in ten task committees are also hereby acknowledged.
The Symbols, Glossary and Appendices to this Specification are an integral part of the
Specification. A non-mandatory Commentary has been prepared to provide background for
the Specification provisions and the user is encouraged to consult it. Additionally, non-
mandatory User Notes are interspersed throughout the Specification to provide concise and
practical guidance in the application of the provisions.
The reader is cautioned that professional judgment must be exercised when data or rec-
ommendations in the Specification are applied, as described more fully in the disclaimer
notice preceding this Preface.
This Specification was approved by the Committee on Specifications:
