11、l Construction Manual is dedicated to Robert O. Disque, a retired AISC staff member and long-time member of the AISC Committee on Manuals. Bob, or Mr. Steel, as his friends on the Committee call him, worked closely with the Committee on Manuals, developing the 1st Edition of the LRFD Manual of Steel

12、 Construction and the 9th Edition ASD Manual of Steel Construction. After retiring from AISC in 1991, Bob continued to be involved with the Committee as a member. He joined AISC in 1959, after working as a structural designer for firms in Philadelphia and New York. His career at AISC began as a Dist

13、rict Engineer in Pittsburgh, where he mar- keted to architects and engineers by providing them with the latest technical information on structural steel. After a brief period as Assistant Chief Engineer, he was promoted to Chief Engineer in 1963 at AISC headquarters, which, at that time, was in New

14、York City. In this capacity, Bob supervised 32 engineers throughout the country. In 1964, he launched the first AISC lecture series on steel design, educating thousands of engineers across the country on various topics related to steel design and construction. In 1979, Bob left AISC for a brief stin

15、t as an associate professor of Civil Engineering at the University of Maine, only to return to AISC a few years later as Assistant Director of Engineering in Chicago, where AISC made its home in the early 1980s. It was at this time that he worked on the development of the two aforementioned AISC Man

16、uals. In 1991, Bob retired from AISC and joined the consulting firm of Gibble, Norden, Champion and Brown in Old Saybrook, Connecticut. Bob invented many things that today are the norm. He created the “snug tight” concept for bolted joints, in conjunction with his contemporary and fellow Manual Comm

17、ittee mem- ber Ted Winneberger of W the astute reader will also note that it incorporates his initials. He advanced the use of flexible moment connections, formerly known as “Type 2 with Wind Connections,” as a simplified and economical design approach based on the beneficial inelastic behavior of s

18、teel. Bob shared his knowledge of structural steel by authoring numerous papers and the textbook, Applied Plastic Design of Steel. He also co-authored the textbook, Load and Resistance Factor Design of Steel Structures, with Louis F. Geschwindner and Reidar Bjorhovde. Of greatest importance to this

19、Manual, however, Bob always emphasized that the Manual is not a text- book, but rather a handbook to provide design guidance and aids for practicing engineers. For all that he has done to advance the practice of structural steel design, this Committee of friends and former colleagues is pleased to d

20、edicate this 15th Edition Manual to Mr. Steel. AISC_Prelims_15th Ed. 2017-03-29 12:51 PM Page vFOREWORD The American Institute of Steel Construction, founded in 1921, is the nonprofit technical standards developer and trade organization for the fabricated structural steel industry in the United Stat

21、es. 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 the engineering, research and development activities of the Institute make po

22、ssible 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, detailers, service consultants, software developers, and steel product manufacturer

23、s; Professional Members, who are structural or civil engineers and architects, including archi- tectural and engineering educators; Affiliate Members, who include general contractors, building inspectors and code officials; and Student Members. The Institutes objective is to make structural steel th

24、e 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, standardization and market development. To accomplish this objective, the

25、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 Specification for Structural Steel Buildings and the Code of Standard Pract

26、ice 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, Modern Steel Construction magazine, and other design aids and research reports.

28、Steel Construction Manual, which was first published in 1927. It replaces the 14th Edition Manual originally published in 2011. The following specifications, codes and standards are printed in Part 16 of this Manual: 2016 AISC Specification for Structural Steel Buildings 2014 RCSC Specification for

29、Structural Joints Using High-Strength Bolts 2016 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: A I S CDesign Examples, which illustrate the application of tables and specification p

30、rovisions that are included in this Manual. A I S CShapes Database V15.0 and V15.0H. Background and supporting literature (references) for the AISC Steel Construction Manual. The following major changes and improvements have been made in this revision: All tabular information and discussions are upd

31、ated to comply with the 2016 Specif i - cation for Structural Buildings, and the standards and other documents referenced therein. Shape information is updated to ASTM A6/A6M-14 throughout this Manual. Larger pipe, HSS and angle sizes have also been incorporated into the dimensions and prop- erties

32、tables in Part 1. The available compressive strength tables are expanded to include 65- and 70-ksi steel for a limited number of shapes. In Part 6, a new design aid is included that provides the width-to-thickness slenderness limits for various steel strengths. In Part 6, a new design aid is include

33、d that provides the available flexural strength, available shear strength, available compressive strength, and available tensile strength for W-shapes in one table. In Part 9, a new interaction equation is provided for connection design based on a plastic strength approach. In Part 9, a new approach

34、 to designing coped beams is presented based on recent studies. In addition, many other improvements have been made throughout this Manual.

39、structures. The design of seismic force-resisting systems also must meet the requirements in the AISC Seismic Provisions for Structural Steel Buildings, except in the following cases for which use of the AISC Seismic Provisions is not required: Buildings and other structures in seismic design catego

40、ry (SDC) A Buildings and other structures in SDC B or C with R = 3 systems steel systems not specifically detailed for seismic resistance per ASCE/SEI 7 Table 12.2-1 (ASCE, 2016) Nonbuilding structures similar to buildings with R = 1 1 /2 braced-frame systems or R = 1 moment-frame systems (see ASCE/

41、SEI 7 Table 15.4-1) Nonbuilding structures not similar to buildings (see ASCE/SEI 7 Table 15.4-2), which are designed to meet the requirements in other standards entirely Conversely, use of the AISC Seismic Provisions is required in the following cases: Buildings and other structures in SDC B or C w

42、hen one of the exemptions for steel seismic force-resisting systems above does not apply Buildings and other structures in SDC B or C that use composite seismic force-resist- ing systems (those containing composite steel-and-concrete members and those composed of steel members in combination with re

43、inforced concrete members) Buildings in SDC D, E or F Nonbuilding structures in SDC D, E or F, when the exemption above does not apply The AISC Seismic Design Manual provides guidance on the use of the AISC Seismic Provisions. The Manual consists of seventeen parts addressing various topics related

44、to steel building design and construction. Part 1 provides the dimensions and properties for structural products commonly used. For proper material specifications for these products, as well as general spec- ification requirements and other design considerations, see Part 2. For the design of member

45、s, see Parts 3 through 6. For the design of connections, see Parts 7 through 15. For Specifications and Codes, see Part 16. For other miscellaneous information, see Part 17. Tables in the Manual that present available strengths are developed using the geometric con- ditions indicated and the applica

46、ble limit states from the AISC Specification for Structural Steel Buildings. Given the nature of the tables, and the possible governing limit state for each table value, linear interpolation between tabulated values may or may not provide correct strengths.
