The quality and testing of materials discussed in this document

27、onsiderations of Committee 332 in developing the provisions contained herein. Explanation of the departure of this code from ACI 318 is emphasized. Comments on specific provisions are made under the corresponding chapter and section numbers of this code.The commentary is not intended to provide a co

28、mplete historical background concerning the development of this code, nor is it intended to provide a detailed rsum of the studies and research data reviewed by the committee in formulating this document.This code is meant to be used as part of a legally adopted building code and, as such, must diff

29、er in form and substance from documents that provide detailed specifications, recommended practice, or complete design procedures.This code is intended to cover all residential structures that fall within the scope of the International Residential Code (IRC-2012). Requirements more stringent than th

30、e code provisions may be desirable for large, complex, or irregular structures; high-hazard areas; and other unusual construction. This code cannot replace sound engineering knowledge, experience, and judgment.A building code states only the minimum requirements necessary to provide for public healt

31、h and safety; this code is based on this principle. For any structure, the owner or the designer may require the quality of materials and construction to be higher than the minimum requirements necessary to protect the public as stated herein. Lower standards, however, are not permitted. The comment

32、ary directs attention to other documents that provide suggestions for carrying out the requirements and intent of this code.This code has no legal status unless adopted by government bodies having authority to regulate building design and construc-tion. Where this code has not been adopted, it may s

33、erve as a reference to good practice even though it has no legal status.This code provides a means of establishing minimum standards for acceptance of designs and construction by legally appointed building officials or their designated representatives. This document is not intended for use in settli

34、ng disputes between the owner; engineer; architect; contractor; or their agents, subcontractors, material suppliers, or testing agencies. Therefore, this code cannot define the contract responsibility of each of the parties in construction. General references requiring compliance with this code in t

35、he project specifications should be avoided because the contractor is rarely in a position to accept responsibility for design details or construction requirements that depend on detailed knowledge of the design. Design-build construction contractors, however, typically combine the design and constr

36、uction responsibility. Generally, the drawings, spec-ifications, and contract documents should contain all the necessary requirements to ensure compliance with the code. In part, this can be accomplished by reference to specific code sections in the project specifications. Other ACI publications, su

37、ch as ACI 301, are written specifically for use as contract documents for construction. Testing and certification programs should be provided for the individual parties involved with the execution of work performed in accordance with this code.American Concrete Institute Copyrighted Materialwww.conc

39、This code, when legally adopted as part of a general building code, provides minimum requirements for design and construction of residential concrete elements. In areas without a legally adopted building code and lack of a project specification, this code defines minimum acceptable stan-dards of des

40、ign and construction practice.1.1.2 This code supplements the general building code and governs matters pertaining to design and construction of cast-in-place concrete construction for one- and two-family dwellings and multiple single-family dwellings (town-houses), and their accessory structures, e

41、xcept wherever this code conflicts with requirements in the legally adopted general building code.1.1.3 Where this code conflicts with requirements contained in other standards referenced in this code, this code shall govern.1.1.4 This code is limited to design and construction of concrete footings,

42、 including thickened slab footings, wall footings, and isolated footings; concrete basement or foun-dation walls constructed with removable forms or with flat insulating concrete forms; and concrete slabs-on-ground.1.1.5 Where the scope of this code and the scope of ACI 318 coincide, design in accor

43、dance with ACI 318 shall be permitted for all buildings and structures, and all parts thereof, within the scope of this code.1.1.6 This code does not govern design and construction of insulating concrete form walls with a waffle or screen configuration; precast wall elements; above-grade concrete wa

44、lls; deep foundation systems, such as piles, drilled piers, or caissons; and elevated concrete slabs.1.1.7 This code does not govern the design and applica-tion of systems for surface drainage, waterproofing, damp-proofing, or the ventilation of radon gases.1.1.8 When a building or structure contain

45、s elements that exceed the limits of this code or otherwise do not conform to this code, these elements shall be designed in accordance with ACI 318.1.1.9 Where permitted by the statutes of the jurisdiction where the project is to be constructed, construction docu-ments for residences designed by th

46、e provisions of this code need not be prepared by a licensed design professional. Where required by the statutes of the jurisdiction where the R1GENERAL R1.1Scope R1.1.1 The user of this code should consult the applicable general building code for all applied loads to determine the applicable values

47、 for design requirements. In the absence of a governing code, the user should consider the use of ASCE/SEI 7 to determine applicable loads.R1.1.3 The International Residential Code (IRC-2012) references this code. Where the design of an element is initi-ated with this code from reference by the IRC-

48、2012, the entire design of the element must be completed using the provisions of this code.R1.1.4 The design and construction requirements for foot-ings, foundation walls, and slabs-on-ground are included in this code, together with requirements for concrete, rein-forcement, forms, and other related

49、 materials.R1.1.6 Provisions for application of precast wall elements are found in IRC-2012. The provisions for above-grade concrete walls are currently available in IRC-2012 based on PCA 100.R1.1.7 Guidance on the type and application of systems for drainage, waterproofing, dampproofing, and radon gas ventilation are commonly found in the general building code.American Concrete Institute Copyrighted Materialwww.concrete.orgRESIDENTIAL CODE REQUIREMENTS FOR STRUCTURAL CONCRETE (ACI 332-14) AND COMMENTARY 5CODE COMMENTARYproject is to
