4、 the AISC Seismic Design Manual is dedicated to the memory of Clarkson W. Pinkham, a long-time member of the AISC Committee on Specifications and TaskCommittee 9Seismic Design. Mr. Pinkham, or Pinky as he was affectionately known to his professional colleagues, was president and member of the Los An

5、geles consulting struc-tural engineering firm, S.B. Barnes and Associates, for 62 years. He served on the AISCCommittee on Specifications from the mid-1970s until the year 2000, and Task Committee9Seismic Design from the mid-1990s until 2010. As a member of Task Committee 9 andtechnical secretary fo

6、r the 1997 AISC Seismic Provisions for Structural Steel Buildings, hewas a major contributor and instrumental in the early development of that standard. Pinkywas one of the first proponents of including composite systems in the AISC SeismicProvisions and, for the first time, this Seismic Design Manu

7、al includes two chapters on suchsystems. Pinky received the AISC Lifetime Achievement Award in 1999. Through a careerthat spanned more than six decades, he spent a lifetime sharing his expertise with others inthe field. He was passionate about learning up until his death in 2012 at the age of 92. Pi

8、nkywas generous in sharing his abundance of structural engineering experience and knowledgethrough committee involvement and with those who requested it on the subjects of structuralsteel, concrete and masonry design, cold-formed structures, and timber. By providing solu-tions and recommendations in

9、 this way, Pinky improved the integrity of numerousstructures; in particular, their capacity to resist seismic-generated forces. He was electedpresident of the Structural Engineers Association of Southern California (SEAOSC) in1971, and later served as president of the Structural Engineers Associati

10、on of California(SEAOC) in 1975. He was twice given the S.B. Barnes Award for Research, and in 1994 was inducted into the SEAOC College of Fellows, the highest honor awarded by SEAOC. In 2009, the Structural Engineering Institute of the American Society of Civil Engineersawarded Pinky the Walter P.

11、Moore, Jr., Award in recognition of his dedication to and tech-nical expertise in the development of structural codes and standards. AISC will alwaysremember his dedication to the development of standards related to the design and con-struction of structural steel and it is especially fitting that t

19、, 14th Edition.The following consensus standards are printed in Part 9 of this Manual: 2010 Seismic Provisions for Structural Steel Buildings (ANSI/AISC 341-10) 2010 Prequalified Connections for Special and Intermediate Steel Moment Frames for Seismic Applications including Supplement No. 1 (ANSI/AI

20、SC 358-10 and ANSI/AISC 358s1-11)The design examples contained in this Manual demonstrate an approach to design, andare not intended to suggest that the approach presented is the only approach. The commit-tee responsible for the development of these design examples recognizes that designers havealte

21、rnate approaches that work best for them and their projects. Design approaches that dif-fer from those presented in these examples are considered viable as long as the AISCSpecification and AISC Seismic Provisions, sound engineering, and project specific require-ments are satisfied.The following maj

26、chnicalspecifying and trade organization for the fabricated structural steel industry in the UnitedStates. Executive and engineering headquarters of AISC are maintained in Chicago. TheInstitute is supported by four classes of membership: Active Members engaged in the fab-rication, production and sal

27、e of structural steel; Associate Members, who include Erectors,Detailers, Service Consultants, Software Developers, and Steel Product Manufacturers;Professional Members, who are individuals or firms engaged in the practice of architectureor engineering, including architectural and engineering educat

28、ors; and Affiliate Members,who include General Contractors, Building Inspectors and Code Officials. The continuingfinancial support and active participation of Members in the engineering, research anddevelopment activities of the Institute make possible the publishing of this Seismic DesignManual.Th

29、e Institutes objective is to make structural steel the material of choice, by being theleader in structural-steel-related technical and market-building activities, including: specifi-cation and code development, research, education, technical assistance, quality certification,standardization, and ma

30、rket development. To accomplish this objective, the Institute publishes manuals, design guides and specifi-cations. Best known and most widely used is the Steel Construction Manual, which holds ahighly respected position in engineering literature. The Manual is based on the Specificationfor Structur

31、al Steel Buildings and the Code of Standard Practice for Steel Buildings andBridges. Both standards are included in the Manual for easy reference.The Institute also publishes technical information and timely articles in its EngineeringJournal, Design Guide series, Modern Steel Construction magazine,

32、 and other design aids,research reports, and journal articles. Nearly all of the information AISC publishes is avail-able for download from the AISC web site at www.aisc.org.SM_Prelims_2nd Ed._Nov. 21, 2012 12-11-21 4:24 AM Page viiixiAMERICAN INSTITUTE OF STEEL CONSTRUCTIONSCOPEThe specification re

33、quirements and other design recommendations and considerations sum-marized in this Manual apply in general to the design and construction of seismic forceresisting systems in steel buildings and other structures. The AISC Seismic Design Manualis intended to be applied in conjunction with the AISC St

34、eel Construction Manual, whichprovides guidance on the use of the AISC Specification for Structural Steel Buildings.In addition to the requirements of the AISC Specification, the design of seismic forceresisting systems must meet the requirements in the AISC Seismic Provisions for StructuralSteel Bu

39、of ten parts addressing various topics related to thedesign and construction of seismic force resisting systems of structural steel and structuralsteel acting compositely with reinforced concrete. Part 1 stipulates the specific editions ofthe specifications, codes and standards referenced in this Ma

40、nual, and provides a discussionof general design considerations related to seismic design. Part 2 provides some guidanceon structural analysis procedures employed. For the design of systems not detailed for seis-mic resistance, see Part 3. Parts 4 through 7 apply to the various types of seismic forc

41、eresisting systems, including design examples. Part 8 discusses other systems, such asdiaphragm chords and collectors, which are important in seismic design. Part 10 addressesengineering damping systems. For applicable AISC seismic standards, see Part 9.xAMERICAN INSTITUTE OF STEEL CONSTRUCTIONand t
