6、singthe design and installation of building systems through requirements emphasizing performance.The International Building Code, in this 2012 edition, is designed to meet these needs throughmodel code regulations that safeguard the public health and safety in all communities, large andsmall.This co

7、mprehensive building code establishes minimum regulations for 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 2012 edition is fully compatiblewith all of the Inter

8、national Codes(I-Codes) published by the International Code Council (ICC),including the International Energy Conservation Code, International Existing Building Code, Inter-national Fire Code, International Fuel Gas Code, International Green Construction Code(to beavailable March 2012), International

9、 Mechanical Code, ICC Performance Code, InternationalPlumbing Code, International Private Sewage Disposal Code, International Property MaintenanceCode, International Residential Code, International Swimming Pool and Spa Code (to be avail-able March 2012), International Wildland-Urban Interface Code

10、and International Zoning Code.The International Building Code provisions provide many benefits, among which is the modelcode development process that offers an international forum for building professionals to discussperformance and prescriptive code requirements. This forum provides an excellent ar

11、ena to debateproposed revisions. This model code also encourages international consistency in the application ofprovisions.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 ap

12、pointed by ICC and consisting ofrepresentatives of the three statutory members of the International Code Council at that time,including: Building Officials and Code Administrators International, Inc. (BOCA), International Con-ference of Building Officials (ICBO) and Southern Building Code Congress I

13、nternational (SBCCI). Theintent was to draft a comprehensive set of regulations for building systems consistent with 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,

14、followed by pub-lic hearings in 1997, 1998 and 1999 to consider proposed changes. This 2012 edition presents thecode as originally issued, with changes reflected in the 2003, 2006 and 2009 editions and furtherchanges approved by the ICC Code Development Process through 2010. A new edition such as th

15、is ispromulgated every 3 years.This code is founded on principles intended to establish provisions consistent 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

16、the use of new materials,products or methods of construction; and provisions that do not give preferential treatment to par-ticular types or classes of materials, products or methods of construction.AdoptionThe International Building Code is available for adoption and use by jurisdictions internatio

17、nally. Itsuse within a governmental jurisdiction is intended to be accomplished through adoption by refer-ence in accordance with proceedings establishing the jurisdictions laws. At the time of adoption,jurisdictions should insert the appropriate information in provisions requiring specific local in

18、forma-tion, such as the name of the adopting jurisdiction. These locations are shown in bracketed words insmall capital letters in the code and in the sample legislation. The sample adoption ordinance onpage xix addresses several key elements of a code adoption ordinance, including the informationre

19、quired for insertion into the code text.0b_pref_OregonStruct_2014.fm Page iii Wednesday, May 14, 2014 9:11 AMiv 2014 OREGON STRUCTURAL SPECIALTY CODEMaintenanceThe International Building Code is kept up to date through the review of proposed changes submit-ted by code enforcing officials, industry r

20、epresentatives, 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 both through the Code Development Cycles an

21、dthe 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 Code assures the highest degreeof

22、care, ICC, its members and those participating in the development of this code do not accept anyliability resulting from compliance or noncompliance with the provisions because ICC does not havethe power or authority to police or enforce compliance with the contents of this code. Only the gov-ernmen

23、tal 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, proposed changes to the code are considered at the Code Devel-opment Hearings by the applicable International Building

24、 Code Development Committee (IBC-FireSafety, General, Means of Egress or Structural). Proposed changes to a code section that has a num-ber beginning with a letter in brackets are considered by a different code development committee.For example, proposed changes to code sections that have F in front

25、 of them (e.g., F 903.1.1.1)are considered by the International Fire Code Development Committee during the portion of thecode development hearings when the International Fire Code Development Committee meets.The content of sections in this code that begin with a letter designation is maintained by a

26、nothercode development committee in accordance with the following:A = Administrative Code Development Committee;E = International Energy Conservation Code Development Committee (Commercial EnergyCommittee or Residential Energy Committee, as applicable);EB = International Existing Building Code Devel

27、opment Committee;F = International Fire Code Development Committee;FG = International Fuel Gas Code Development Committee;M = International Mechanical Code Development Committee; andP = International Plumbing Code Development Committee.0b_pref_OregonStruct_2014.fm Page iv Wednesday, May 14, 2014 9:1

28、1 AM2014 OREGON STRUCTURAL SPECIALTY CODE vNote that, for the development of the 2015 edition of the I-Codes, there will be two groups ofcode development committees and they will meet in separate years. The groupings are as follows:Code change proposals submitted for code sections that have a letter

29、 designation in front ofthem will be heard by the respective committee responsible for such code sections. Because differ-ent committees will meet in different years, it is possible that some proposals for this code will beheard by a committee in a different year than the year in which the primary c

30、ommittee for this codemeets. For instance, every section of Chapter 1 of this code is designated as the responsibility of theAdministrative Code Development Committee, and that committee is part of the Group B codehearings. This committee will conduct its code development hearings in 2013 to conside

31、r all codechange proposals for Chapter 1 of this code and proposals for Chapter 1 of all I-Codes. Therefore,any proposals received for Chapter 1 of this code will be deferred for consideration in 2013 by theAdministrative Code Development Committee. Another example is Section 903.1 which is designat

32、ed as the responsibility of the InternationalFire Code Development Committee, along with most of the provisions in Chapter 9. This committeewill conduct its code development hearings in 2013 to consider all code change proposals to theInternational Fire Code and any portions of other codes that it i

33、s responsible for, including Section903.1 and most of the provisions of Chapter 9 (designated with F in front of those sections).Therefore, any proposals received for Section 903.1 in Chapter 9 will be deferred for considerationin 2013 by the International Fire Code Development Committee.In some cas

34、es, another committee in Group A will be responsible for a section of this code. Forexample, Section 1210.3 has a P in front of the numbered section, indicating that this section ofthe code is the responsibility of the International Plumbing Code Development Committee. TheInternational Plumbing Code

35、 is in Group A; therefore, any code change proposals to this section willbe due before the Group A deadline of January 3, 2012, and these code change proposals will beassigned to the International Plumbing Code Development Committee for consideration.It is very important that anyone submitting code

36、change proposals understand which code devel-opment committee is responsible for the section of the code that is the subject of the code changeproposal.

46、ion between the International Building and Fire CodesBecause the coordination of technical provisions is one of the benefits of adopting the ICC family ofmodel codes, users will find the ICC codes to be a very flexible set of model documents. To accom-plish this flexibility some technical provisions

47、 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 adopted as a stand-alone regulation. When one of themodel documents is adopted as the basis of a stand-alone code,

48、 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 of complimentary codes. When adoptedtogether there should be no conflict of any of the technical provisions. When

49、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 multiplemodel documents, the enforcement duties must be clearly assigned by the local adopting jurisdic-tion. ICC remains committed to providing state-of-the-art model cod
