9、ecification for Structural Steel Buildings, July 7, 2016AMERICAN INSTITUTE OF STEEL CONSTRUCTIONPREFACE(This Preface is not part of ANSI/AISC 360-16, Specification for Structural Steel Buildings,but is included for informational purposes only.)This Specification is based upon past successful usage,

10、advances in the state of knowledge,and changes in design practice. The 2016 American Institute of Steel ConstructionsSpecification for Structural Steel Buildings provides an integrated treatment of allowablestrength design (ASD) and load and resistance factor design (LRFD), and replaces earlierSpeci

11、fications. As indicated in Chapter B of the Specification, designs can be made accord-ing to either ASD or LRFD provisions.This ANSI-approved Specification has been developed as a consensus document usingANSI-accredited procedures to provide a uniform practice in the design of steel-framedbuildings

12、and other structures. The intention is to provide design criteria for routine use andnot to provide specific criteria for infrequently encountered problems, which occur in thefull range of structural design.This Specification is the result of the consensus deliberations of a committee of structurale

13、ngineers with wide experience and high professional standing, representing a wide geo-graphical distribution throughout the United States. The committee includes approximatelyequal numbers of engineers in private practice and code agencies, engineers involved inresearch and teaching, and engineers e

14、mployed by steel fabricating and producing compa-nies. The contributions and assistance of more than 50 additional professional volunteersworking in task committees are also hereby acknowledged.The Symbols, Glossary, Abbreviations and Appendices to this Specification are an inte-gral part of the Spe

15、cification. A nonmandatory Commentary has been prepared to providebackground for the Specification provisions and the user is encouraged to consult it.Additionally, nonmandatory User Notes are interspersed throughout the Specification toprovide concise and practical guidance in the application of th

16、e provisions. A number of significant technical modifications have also been made since the 2010edition of the Specification, including the following:Adopted an ASTM umbrella bolt specification, ASTM F3125, that includes Grades A325,A325M, A490, A490M, F1852 and F2280Adopted new ASTM HSS material sp

17、ecifications, ASTM A1085/A1085M and A1065/A1065M, that permit use of a design thickness equal to the full nominal thickness of thememberExpanded the structural integrity provisions applicable to connection designAdded a shear lag factor for welded plates or connected elements with unequal lengthlong
