11、rganization for the fabricated structural steel industry in the United States. AISC is headquartered in Chicago and has a long tradition of service to the steel construction industry providing timely and reliable information. The continuing financial support and active participation of Members in th

12、e engineering, research and development activities of the Institute make possible the publishing of this Steel Construction Manual. Those Members include the following: Full Members engaged in the fabrication, production and sale of structural steel; Associate Members, who include erectors, detailer

13、s, service consultants, software developers and steel product manufactur- ers; Professional Members, who are structural or civil engineers and architects, including architectural and engineering educators; Affiliate Members, who include general contrac- tors, building inspectors and code officials;

14、and Student Members. The Institutes objective is to make structural steel the material of choice, by being the leader in structural-steel-related technical and market-building activities, including specifi- cation and code development, research, education, technical assistance, quality certification

15、, standardization and market 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 a highly respected position in engineering literature. The Manual is based on the

16、 Specification for Structural Steel Buildings and the Code of Standard Practice for Steel Buildings and Bridges. Both standards are included in the Manual for easy reference. The Institute also publishes technical information and timely articles in its Engineering Journal, Design Guide series, Moder

17、n Steel Construction magazine, 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.

18、EFACE This Manual is the 14th Edition of the AISC Steel Construction Manual, which was first published in 1927. It replaces the 13th Edition Manual originally published in 2005. The following specifications, codes and standards are printed in Part 16 of this Manual: 2010 AISC Specification for Struc

19、tural Steel Buildings 2009 RCSC Specification for Structural Joints Using High-Strength Bolts 2010 AISC Code of Standard Practice for Steel Buildings and Bridges The following resources supplement the Manual and are available on the AISC web site at www.aisc.org: AISC Design Examples, which illustra

20、te the application of tables and specification provisions that are included in this Manual. AISC Shapes Database V14.0 and V14.0H. Background and supporting literature (references) for the AISC Steel Construction Manual. The following major changes and improvements have been made in this revision: A

21、ll tabular information and discussions have been updated to comply with the 2010 Specification for Structural Buildings and the standards and other documents refer- enced therein. Shape information has been updated to ASTM A6-09 throughout the Manual, includ- ing a new HP shape series. Eccentrically

22、 loaded weld tables have been revised to indicate the strongest weld per- mitted by the three methods listed in Chapter J of the specification and supplemented to provide strengths for L-shaped welds loaded from either side. The procedure for the design of bracket plates in Part 15 has been revised.

23、 In Part 10, the procedure for the design of conventional single plate shear connections has been revised to accommodate the increased bolt shear strengths of the 2010 Specification for Structural Steel Buildings. In Part 10, for extended single plate shear connections, information is provided to de

24、termine if stiffening plates (stabilizers) are required. In addition, many other improvements have been made throughout this Manual and the number of accompanying design examples has been expanded. By the AISC Committee on Manuals and Textbooks, William A. Thornton, Chairman Edward M. Egan Mark V .

AISC_Prelims:14th Ed. 1/20/11 7:23 AM Page ixx AMERICAN INSTITUTE OF STEEL CONSTRUCTION SCOPE The specification requirements a

29、nd other design recommendations and considerations sum- marized in this Manual apply in general to the design and construction of steel buildings and other structures. The design of seismic force resisting systems also must meet the requirements in the AISC Seismic Provisions for Structural Steel Bu

30、ildings, except in the following cases for which use of the AISC Seismic Provisions is not required: Buildings and other structures in seismic design category (SDC) A Buildings and other structures in SDC B or C with R = 3 systems steel systems not specifically detailed for seismic resistance per AS

34、ismic Design Manual provides guidance on the use of the AISC Seismic Provisions. The Manual consists of seventeen parts addressing various topics related to steel build- ing design and construction. Part 1 provides the dimensions and properties for structural products commonly used. For proper mater
