8、FACE(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 S
9、teel ConstructionsSpecification for Structural Steel Buildings provides an integrated treatment of allowablestress design (ASD) and load and resistance factor design (LRFD), and replaces earlierSpecifications. As indicated in Chapter B of the Specification, designs can be made accord-ing to either A
10、SD or LRFD provisions.This Specification has been developed as a consensus document to provide a uniformpractice 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 infrequentlyencountered
11、 problems, which occur in the full range of structural design.This Specification is the result of the consensus deliberations of a committee of structuralengineers with wide experience and high professional standing, representing a wide geo-graphical distribution throughout the United States. The co
12、mmittee includes approximatelyequal numbers of engineers in private practice and code agencies, engineers involved inresearch and teaching, and engineers employed by steel fabricating and producing compa-nies. The contributions and assistance of more than 50 additional professional volunteersworking
13、 in ten task committees are also hereby acknowledged.The Symbols, Glossary and Appendices to this Specification are an integral part of theSpecification. A non-mandatory Commentary has been prepared to provide background forthe Specification provisions and the user is encouraged to consult it. Addit
14、ionally, non-mandatory User Notes are interspersed throughout the Specification to provide concise andpractical 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 descr
