7、ricanWelding Society (AWS) are voluntary consensus standards that have been developed in accordance with the rules of theAmerican National Standards Institute (ANSI). When AWS American National Standards are either incorporated in, ormade part of, documents that are included in federal or state laws

8、 and regulations, or the regulations of other governmen-tal bodies, their provisions carry the full legal authority of the statute. In such cases, any changes in those AWS standardsmust be approved by the governmental body having statutory jurisdiction before they can become a part of those lawsand

9、regulations. In all cases, these standards carry the full legal authority of the contract or other document that invokesthe AWS standards. Where this contractual relationship exists, changes in or deviations from requirements of an AWSstandard must be by agreement between the contracting parties.AWS

10、 American National Standards are developed through a consensus standards development process that bringstogether volunteers representing varied viewpoints and interests to achieve consensus.

Corbit CB coincident with this, the D1.1code changed references of buildings and bridges to statically loaded and dynamically loaded

29、 structures, respectively, inorder to make the document applicable to a broader range of structural applications. After the publishing of the 2010 edi-tion, it was decided that the AWS Structural Welding CodeSteel would be published on a five year revision cycleinstead of a two year revision cycle.

30、This was done in order to sync the publication cycle of AWS Structural WeldingCode-Steel with the publication cycles of the AISC Steel Building Specification and the International Building Code.This 2015 edition is the 23rd edition of D1.1.Underlined text in the clauses, subclauses, tables, figures,

31、 or forms indicates a change from the 2010 edition. A verticalline in the margin of a table or figure also indicates a change from the 2010 edition.The following is a summary of the most significant technical changes contained in D1.1/D1.1M:2015:The 2015 edition of the code has been reorganized. The

32、 tubular provisions, tables, and figures previously locatedthroughout the code are now within Clause 9 entitled “Tubular Structures.” The reorganization required numerous refer-ence changes and renumbering of the subclauses, tables, and figures. Many of the tables in Clause 4 contained provisionsfor

33、 Plate as well as Pipe or Tubing. The tables have been divided to only include Plate if contained in Clause 4 and Pipeor Tubing if contained in Clause 9. This separation of the information contained in the tables also resulted in manychanges to the footnotes delineated in the tables.Clauses 1, 7, an

34、d 8 have only been slightly impacted by the reorganization. However, Clauses 2, 3, 4, 5, and 6 have beengreatly impacted with the reorganization.Summary of ChangesClause/Table/Figure/Annex ModificationClause 2 The most significant change to Clause 2 from the 2010 edition is that Part D entitled “Spe
