those that areinvolved in the design,purchase,fabrication and erection of structuralsteel.This Code provides a useful framework for a common understandingof the acceptable standards when contracting for structural steel.As such,it is useful for owners,architects,engineers,general contractors,construc-tion managers,fabricators,steel detailers,erectors and others that are asso-ciated with construction in structural steel.Unless specific provisions tothe contrary are contained in the contract documents,the existing tradepractices that are contained herein are considered to be the standard cus-tom and usage of the industry and are thereby incorporated into the rela-tionships between the parties to a contract.,The Symbols and Glossary are an integral part of this Code.Inmany sections of this Code,a non-mandatory Commentary has been pre-pared to provide background and further explanation for the correspondingCode provisions.The user is encouraged to consult it.,Since the first edition of this Code was published in 1924,AISChas continuously surveyed the structural steel design community and con-struction industry to determine standard trade practices.Since then,thisCode has been periodically updated to reflect new and changing technolo-gy and industry practices.,This edition is the fifth complete revision of this Code since it wasfirst published.It is the result of the deliberations of a fair and balancedCommittee,the membership of which included six structural engineers,two architects,one general contractor,seven fabricators,one steel detailer,three erectors and one attorney.The following major changes have beenmade in this revision:,Commentary information,when available,has been placed immediate-ly following its corresponding Code provisions.,The use of the term“Owner”throughout this Code has been generally(but not completely)eliminated,where appropriate.Instead,one orboth of the terms“Owners Designated Representative for Design”and“Owners Designated Representative for Construction”has been used.Both U.S.customary units and metric units have been provided.SeeSection 1.3.,Code of Standard Practice for Steel Buildings and Bridges,March 7,2000,AMERICAN INSTITUTE OF STEEL CONSTRUCTION,iv,Requirements for existing structures have been added to cover demoli-tion and shoring,protection against damage,surveying or field dimen-sioning and hazardous materials.,The classifications of materials in Section 2 have been editoriallyrevised and expanded.,Provisions for the resolution of discrepancies have been added inSection 3.3.,Also in Section 3.3,the order of precedence of contract documents hasbeen changed for simplicity and to reflect current practices.,Provisions for fast-track project delivery have been added in Section3.6.,The responsibilities of the various entities involved in the shop anderection drawing approval process have been simplified and clarified inSection 4.,Issues regarding the use of design drawings by the fabricator and/or theerector are now covered in Section 4.3.,The permissible variation from theoretical curvature for a curved mem-ber is now covered in Section 6.4.2.,Provisions have been added in Section 6.4.5 to cover permissible vari-ations in camber for fabricated trusses.,Section 6.5 has been editorially restructured and substantively modi-fied to recognize that the majority of steel in building structures neednot be primed or painted.,Coverage of bearing devices has been revised:installation of bearingdevices is now covered in Section 7.6 and grouting is covered inSection 7.7.,Use of the terms self-supporting and non-self-supporting has beeneliminated and replaced with the provisions for temporary support inSection 7.10.,Provisions in Section 7.10.3 for the loads that must be considered dur-ing erection have been revised.,The intent of the provisions that address the accumulation of mill tol-erances and fabrication tolerances and their relationship to the erectiontolerances has been clarified in Section 7.12.,Quality-assurance provisions in Section 8 have been revised to recog-nize both the AISC Quality Certification program for fabricators andthe AISC Erector Certification program.,Code of Standard Practice for Steel Buildings and Bridges,March 7,2000,AMERICAN INSTITUTE OF STEEL CONSTRUCTION,vAESS requirements for welds have been clarified in Sections 10.2.5.AESS requirements for HSS weld seams have been added in Section10.2.8.In addition,many other changes have been made throughout this Code.By the AISC Committee on the Code of Standard
