PRINTED IN THE U.S.A.2015 INTERNATIONAL BUILDING CODEiiiPREFACEIntroductionInternationally, code officials recognize the need for a modern, up-to-date building code addressingthe design and installation of building systems through r
6、equirements emphasizing performance.The International Building Code, in this 2015 edition, is designed to meet these needs throughmodel code regulations that safeguard the public health and safety in all communities, large andsmall.This comprehensive building code establishes minimum regulations for
7、 building systems usingprescriptive and performance-related provisions. It is founded on broad-based principles that makepossible the use of new materials and new building designs. This 2015 edition is fully compatiblewith all of the International Codes(I-Codes) published by the International Code C
8、ouncil (ICC),including the International Energy Conservation Code, International Existing Building Code, Inter-national Fire Code, International Fuel Gas Code, International Green Construction Code, Interna-tional Mechanical Code, ICC Performance Code, International Plumbing Code, InternationalPriva
9、te Sewage Disposal Code, International Property Maintenance Code, International Residen-tial Code, International Swimming Pool and Spa Code, International Wildland-Urban InterfaceCode and International Zoning Code.The International Building Code provisions provide many benefits, among which is the m
10、odelcode development process that offers an international forum for building professionals to discussperformance and prescriptive code requirements. This forum provides an excellent arena to debateproposed revisions. This model code also encourages international consistency in the application ofprov
11、isions.DevelopmentThe first edition of the International Building Code (2000) was the culmination of an effort initiatedin 1997 by the ICC. This included five drafting subcommittees appointed by ICC and consisting ofrepresentatives of the three statutory members of the International Code Council at
12、that time,including: Building Officials and Code Administrators International, Inc. (BOCA), International Con-ference of Building Officials (ICBO) and Southern Building Code Congress International (SBCCI). Theintent was to draft a comprehensive set of regulations for building systems consistent with
13、 andinclusive of the scope of the existing model codes. Technical content of the latest model codes pro-mulgated by BOCA, ICBO and SBCCI was utilized as the basis for the development, followed by pub-lic hearings in 1997, 1998 and 1999 to consider proposed changes. This 2015 edition presents thecode
14、 as originally issued, with changes reflected in the 2003, 2006, 2009 and 2012 editions and fur-ther changes approved by the ICC Code Development Process through 2014. A new edition such asthis is promulgated every 3 years.This code is founded on principles intended to establish provisions consisten
15、t with the scope of abuilding code that adequately protects public health, safety and welfare; provisions that do notunnecessarily increase construction costs; provisions that do not restrict the use of new materials,products or methods of construction; and provisions that do not give preferential t
16、reatment to par-ticular types or classes of materials, products or methods of construction.AdoptionThe International Code Council maintains a copyright in all of its codes and standards. Maintainingcopyright allows the ICC to fund its mission through sales of books, in both print and electronic for-
17、mats. The International Building Code is designed for adoption and use by jurisdictions that recog-nize and acknowledge the ICCs copyright in the code, and further acknowledge the substantialshared value of the public/private partnership for code development between jurisdictions and theICC.The ICC
18、also recognizes the need for jurisdictions to make laws available to the public. AllICC codes and ICC standards, along with the laws of many jurisdictions, are available for freeiv 2015 INTERNATIONAL BUILDING CODEin a nondownloadable form on the ICCs website. Jurisdictions should contact the ICC ata
19、doptionsiccsafe.org to learn how to adopt and distribute laws based on the InternationalBuilding Code in a manner that provides necessary access, while maintaining the ICCs copy-right.MaintenanceThe International Building Code is kept up to date through the review of proposed changes submit-ted by c
20、ode enforcing officials, industry representatives, design professionals and other interestedparties. Proposed changes are carefully considered through an open code development process inwhich all interested and affected parties may participate.The contents of this work are subject to change through
21、both the code development cycles andthe governmental body that enacts the code into law. For more information regarding the codedevelopment process, contact the Codes and Standards Development Department of the Interna-tional Code Council.While the development procedure of the International Building
22、 Code ensures the highest degreeof care, the ICC, its members and those participating in the development of this code do not acceptany liability resulting from compliance or noncompliance with the provisions because the ICC doesnot have the power or authority to police or enforce compliance with the
23、 contents of this code.Only the governmental body that enacts the code into law has such authority.Code Development Committee Responsibilities(Letter Designations in Front of Section Numbers)In each code development cycle, code change proposals to this code are considered at the CodeDevelopment Hear
24、ings by 11 different code development committees. Four of these committeeshave primary responsibility for designated chapters and appendices as follows:IBC Fire Safety Code Development Committee BF: Chapters 7, 8, 9, 14, 26IBC General Code Development Committee BG: Chapters 2, 3, 4, 5, 6, 12, 27, 28
25、, 29, 30, 31, 32, 33, Appendices A, B, C, D, KIBC Means of Egress Code Development Committee BE: Chapters 10, 11, Appendix EIBC Structural Code Development Committee BS: Chapters 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, Appendices F, G, H, I, J, L, MCode change proposals to sections of the code t
26、hat are preceded by a bracketed letter designa-tion, such as A, will be considered by a committee other than the building code committee listedfor the chapter or appendix above. For example, proposed code changes to Section F 307.1.1 willbe considered by the International Fire Code Development Commi
27、ttee during the Committee ActionHearing in the 2016 (Group B) code development cycle.Another example is Section BF 1505.2. While code change proposals to Chapter 15 are primar-ily the responsibility of the IBC Structural Code Development Committee, which considers codechange proposals during the 201
28、6 (Group B) code development cycle, Section 1505.2 is the respon-sibility of the IBC Fire Safety Code Development Committee, which considers code change propos-als during the 2015 (Group A) code development cycle.The bracketed letter designations for committees responsible for portions of this code
29、are as fol-lows:A = Administrative Code Development Committee;BE = IBC Means of Egress Code Development Committee;2015 INTERNATIONAL BUILDING CODEvBF = IBC Fire Safety Code Development Committee;BG = IBC General Code Development Committee;BS = IBC Structural Code Development Committee;E = Internatio
30、nal Energy Conservation Code Development Committee (Commercial EnergyCommittee or Residential Energy Committee, as applicable);EB = International Existing Building Code Development Committee;F = International Fire Code Development Committee;FG = International Fuel Gas Code Development Committee;M =
31、International Mechanical Code Development Committee; andP = International Plumbing Code Development Committee.For the development of the 2018 edition of the I-Codes, there will be three groups of code devel-opment committees and they will meet in separate years. Note that these are tentative groupin
32、gs.Note: Proposed changes to the ICC Performance Code will be heard by the code development committee noted in brackets in the text of the code.Code change proposals submitted for code sections that have a letter designation in front ofthem will be heard by the respective committee responsible for s
33、uch code sections. Because differ-ent committees hold code development hearings in different years, proposals for this code will beheard by committees in both the 2015 (Group A) and the 2016 (Group B) code development cycles.Group A Codes(Heard in 2015, Code Change Proposals Deadline: January 12, 20

38、i 2015 INTERNATIONAL BUILDING CODEFor instance, every section of Chapter 16 is the responsibility of the IBC Structural Committee,and, as noted in the preceding table, that committee will hold its committee action hearings in 2016to consider code change proposals for the chapters for which it is res
39、ponsible. Therefore any pro-posals received for Chapter 16 of this code will be assigned to the IBC Structural Committee, whichwill consider code change proposals in 2016, during the Group B code change cycle.As another example, every section of Chapter 1 of this code is designated as the responsibi
40、lity ofthe Administrative Code Development Committee, and that committee is part of the Group B por-tion of the hearings. This committee will hold its committee action hearings in 2016 to consider allcode change proposals for Chapter 1 of this code and proposals for Chapter 1 of all I-Codes exceptth
41、e International Energy Conservation Code, International Residential Code and ICC PerformanceCode. Therefore, any proposals received for Chapter 1 of this code will be assigned to the Adminis-trative Code Development Committee for consideration in 2016.It is very important that anyone submitting code
42、 change proposals understand which code devel-opment committee is responsible for the section of the code that is the subject of the code changeproposal.

43、gsSolid vertical lines in the margins within the body of the code indicate a technical change from therequirements of the 2012 edition. Deletion indicators in the form of an arrow ( ) are provided inthe margin where an entire section, paragraph, exception or table has been deleted or an item in alis
44、t of items or a table has been deleted.A single asterisk * placed in the margin indicates that text or a table has been relocated withinthe code. A double asterisk * placed in the margin indicates that the text or table immediatelyfollowing it has been relocated there from elsewhere in the code. The

47、ICC codes to be a very flexible set of model documents. To accom-plish this flexibility some technical provisions are duplicated in some of the model code documents.While the International Codes are provided as a comprehensive set of model codes for the builtenvironment, documents are occasionally a
48、dopted as a stand-alone regulation. When one of themodel documents is adopted as the basis of a stand-alone code, that code should provide a com-plete package of requirements with enforcement assigned to the entity for which the adoption isbeing made.The model codes can also be adopted as a family o
49、f complementary codes. When adoptedtogether there should be no conflict of any of the technical provisions. When multiple model codesare adopted in a jurisdiction, it is important for the adopting authority to evaluate the provisions ineach code document and determine how and by which agency(ies) they will be enforced. It isimportant, therefore, to understand that where technical provisions are duplicated in mu
