13、d construction of cast-in-place concrete for one- and two-familydwellings and multiple single-family dwellings (townhouses), and theiraccessory structures.Among the subjects covered are the design and construction require-ments for plain and reinforced concrete footings, foundation walls, andslabs-o

14、n-ground, and requirements for concrete, reinforcement, forms, andother related materials.The quality and testing of materials discussed in this document arecovered by reference to the appropriate ASTM standards.The Code is written to allow for reference by adoption in a generalbuilding code without

15、 changing its language. Background details orsuggestions for carrying out the requirements or intent of the Code areprovided in the commentary. The commentary discusses some of theconsiderations of the committee in developing the Code with emphasisgiven to the explanation of provisions that may be u

26、CI 332M-10 discusses some of theconsiderations of Committee 332 in developing the provisionscontained in “Residential Code Requirements for StructuralConcrete (ACI 332M-10),” hereinafter called the “Code.”Explanation of the departure of this Code from ACI 318M isemphasized. Comments on specific prov

27、isions are made underthe corresponding chapter and section numbers of the Code.The commentary is not intended to provide a completehistorical background concerning the development of theCode, nor is it intended to provide a detailed rsum of thestudies and research data reviewed by the committee info

28、rmulating the Code.However, references to some research data are providedfor those who wish to study the background material indepth. The Code is meant to be used as part of a legallyadopted building code and, as such, must differ in formand substance from documents that provide detailedspecificatio

29、ns, recommended practice, or completedesign procedures.The Code is intended to cover all residential structures thatfall within the scope of the International Residential Code(IRC). Requirements more stringent than the Code provisionsmay be desirable for large, complex or irregular structures,high-h

30、azard areas, and other unusual construction. The Codeand commentary cannot replace sound engineering knowledge,experience, and judgment.A building code states only the minimum requirementsnecessary to provide for public health and safety. The Codeis based on this principle. For any structure, the ow

31、ner or thedesigner may require the quality of materials and constructionto be higher than the minimum requirements necessary toprotect the public as stated in the Code. However, lowerstandards are not permitted. The commentary directs attentionto other documents that provide suggestions for carrying

32、 outthe requirements and intent of the Code. However, thosedocuments and the commentary are not a part of the Code.The Code has no legal status unless adopted by governmentbodies having authority to regulate building design andconstruction. Where the Code has not been adopted, it mayserve as a refer

33、ence to good practice even though it has nolegal status.The Code provides a means of establishing minimumstandards for acceptance of designs and construction bylegally appointed building officials or their designatedrepresentatives. The Code and commentary are not intendedfor use in settling dispute

34、s between the owner, engineer,architect, contractor, or their agents, subcontractors, materialsuppliers, or testing agencies. Therefore, the Code cannotdefine the contract responsibility of each of the parties inconstruction. General references requiring compliance withthe Code in the project specif

35、ications should be avoidedbecause the contractor is rarely in a position to acceptresponsibility for design details or construction requirementsthat depend on detailed knowledge of the design. Design-build construction contractors, however, typically combinethe design and construction responsibility

36、. Generally, thedrawings, specifications, and contract documents shouldcontain all the necessary requirements to ensure compliancewith the Code. In part, this can be accomplished by referenceto specific Code sections in the project specifications. Other ACIpublications, such as ACI 301M, are written

37、 specifically for use ascontract documents for construction. Testing and certificationprograms should be provided for the individual partiesinvolved with the execution of work performed in accordancewith this Code.ACI 332.1R is a companion document to the Code thatprovides practical information abou

38、t the quality constructionof residential concrete elements conforming to this Code.ACI 332.1R provides detailed information on systems forproduction, placement, finishing, and testing residentialconcrete along with considerations for such issues as insulation,hot and cold weather precautions, curing

39、, and forming.

40、ncrete.CHAPTER 1GENERAL1.1Scope1.1.1 This Code, when legally adopted as part of a generalbuilding code, provides minimum requirements for designand construction of residential concrete elements. In areaswithout a legally adopted building code, this Code definesminimum acceptable standards of design

41、and constructionpractice.R1.1.1 The user of this Code should consult the applicablegeneral building code for all applied loads to determine theapplicable values for design requirements. In the absence ofa governing code, the user should consider the use of ASCE/SEI 7 to determine applicable loads.1.

42、1.2 This Code supplements the general building codeand governs matters pertaining to design and construction ofcast-in-place concrete construction for one- and two-familydwellings and multiple single-family dwellings (town-houses), and their accessory structures, except wherever thisCode conflicts w

43、ith requirements in the legally adoptedgeneral building code.1.1.3 Where this Code conflicts with requirementscontained in other standards referenced in this Code, thisCode shall govern.R1.1.3 The IRC references this Code. Where the design ofan element is initiated with this Code from reference by t

44、heIRC, the entire design of the element must be completedusing the provisions of this Code.1.1.4 This Code is limited to design and construction ofconcrete footings, including thickened slab footings, wallfootings, and isolated footings; concrete basement or foun-dation walls constructed with remova

45、ble forms or with flatinsulating concrete forms; and concrete slabs-on-ground.R1.1.4 The design and construction requirements forfootings, foundation walls, and slabs-on-ground areincluded in this Code, together with requirements forconcrete, reinforcement, forms, and other related materials.1.1.5 W

46、here the scope of this Code and the scope of ACI318M coincide, design in accordance with ACI 318M shallbe permitted for all buildings and structures, and all partsthereof, within the scope of this Code.1.1.6 This Code does not govern design and constructionof insulating concrete form walls with a wa

47、ffle or screenconfiguration; precast wall elements; above-grade concretewalls; deep foundation systems, such as piles, drilled piers,or caissons; and elevated concrete slabs.R1.1.6 Provisions for application of precast wall elementsare found in the International Residential Code (IRC) andother publi

48、cations. The provisions for above-grade concretewalls are currently available in the 2009 IRC based on thePCA 100 Standard or directly found in the PCA 100 Standard.1.1.7 This Code does not govern the design and application ofsystems for surface drainage, waterproofing, dampproofing,and the ventilat

49、ion of radon gases.R1.1.7 Guidance on the type and application of systemsfor drainage, waterproofing, dampproofing, and radon gasventilation are commonly found in the general building code.1.1.8 When a building or structure contains elements thatexceed the limits of this Code or otherwise do not conformto this Code, these elements shall be designed in accordancewith ACI 318M.1.1.9 Where permitted by the statutes of the jurisdictionwhere the project is to be constructed, construction documentsfor residences designed by the provisions of th
