AWS D1.1 BI

http://www.documentbays.org/77226-aws-d11-bi.html

AWS D1.1, Structural Welding Code—Steel, is prepared by the AWS Structural Welding Committee. Because theCode is written in the form of a specification, it cannot present background material or discuss the committee’s intent.Since the publication of the first edition of the Code, the nature of inquiries directed to the American Welding Societyand the Structural Welding Committee has indicated that there are some requirements in the Code that are either difficultto understand or not sufficiently specific, and others that appear to be overly conservative.It should be recognized that the fundamental premise of the Code is to provide general stipulations applicable to anysituation and to leave sufficient latitude for the exercise of engineering judgement. Another point to be recognized is thatthe Code represents the collective experience of the committee; and, while some provisions may seem overly conservative,they have been based on sound engineering practice.The format of this document presents Code interpretations grouped according to the Code date. Individual inquiriesfor the specific issue date of the Code are arranged by the applicable section number within the Code. To assist thereader, an index is provided that is compiled by subject matter, and a second index is provided that supplies the varioussection numbers referenced in the document in numerical order, regardless of Code date.Readers are reminded that the basic format of the Code was reorganized extensively in the 1996 edition. Therefore,the provision numbers of the interpretations included herein in most cases will not be similar to the provision numbers ofeditions for 1996 or later.This is the second edition of this document, and it is the intent of the Society to provide an updated version of thispublication on a frequent schedule. The first edition of this document was published in 2000.Recent official interpretations of AWS D1.1 technical requirements are published regularly in the July and Novemberissues of the Welding Journal. Original requests for official interpretation of any Code requirement shall be submitted inwriting to the Managing Director of Technical Services, American Welding Society, 550 N.W.
