Supplement No. 1AMERICAN INSTITUTE OF STEEL CONSTRUCTIONPREFACE(This Preface is not part of ANSI/AISC 358-10, Prequalified Connections for Special andIntermediate Steel Moment Frames for Seismic Applications, but is included for informa-tional purposes only.)This edition of the St

10、andard was developed using a consensus process in concert with theSpecification for Structural Steel Buildings (ANSI/AISC 360-10) and Seismic Provisions forStructural Steel Buildings (ANSI/AISC 341-10). This Standard is incorporated by referencein the Seismic Provisions. The most significant modific

11、ation to this edition of the Standard is the incorporation ofthree prequalified connections into the body of the standard that were previously part of asupplement (Chapters 7, 8, and 9). It is anticipated that future supplements will be issued asadditional moment connections become prequalified.This

12、 printing includes Supplement No. 1 to Prequalified Connections for Special andIntermediate Steel Moment Frames for Seismic Applications (ANSI/AISC 358s1-11) whichconsists of the material in Chapter 10. The Supplement was finalized shortly after the com-pletion of this Standard.The Symbols, Glossary

13、, and Appendices to this Standard are an integral part of theStandard. A non-mandatory Commentary has been prepared to provide background for theprovisions of the Standard and the user is encouraged to consult it. Additionally, non-manda-tory User Notes are interspersed throughout the Standard to pr

14、ovide concise and practicalguidance in the application of the provisions.The reader is cautioned that professional judgment must be exercised when data or rec-ommendations in this Standard are applied, as described more fully in the disclaimer noticepreceding the Preface.This Standard was approved b
