Such structur

15、es are used for conveying, storing, or treatingliquid or other materials such as solid waste. They include ancillary structures for dams, spill-ways, andchannels.They are subject to uniquely different loadings, more severe exposure conditions, and more restrictiveserviceability requirements than non

16、-environmental building structures.Loadings include normal dead and live loads and vibrating equipment or hydrodynamic forces. Expo-sures include concentrated chemicals, alternate wetting and drying, and freezing and thawing of saturatedconcrete. Serviceability requirements include liquid-tightness

17、or gas-tightness.Typical structures include conveyance, storage, and treatment structures.Proper design, materials, and construction of environmental engineering concrete structures arerequired to produce serviceable concrete that is dense, durable, nearly impermeable, and resistant tochemicals, wit

18、h limited deflections and cracking. Leakage must be controlled to minimize contamination ofground water or the environment, to minimize loss of product or infiltration, and to promote durability.This code presents new material as well as modified portions of the ACI 318-02 Building Code that areappl

19、icable to environmental engineering concrete structures.Because ACI 350-06 is written as a legal document, it may be adopted by reference in a general buildingcode or in regulations governing the design and construction of environmental engineering concrete struc-tures. Thus, it cannot present backg

20、round details or suggestions for carrying out its requirements or intent.It is the function of the commentary to fill this need.CODE REQUIREMENTS FOR ENVIRONMENTAL ENGINEERING CONCRETE STRUCTURESAND COMMENTARY (ACI 350-06)REPORTED BY ACI COMMITTEE 350ACI 350-06 was adopted as a standard of the Ameri

26、. The commentary discusses someof the considerations of Committee ACI 350 in developing“Code Requirements for Environmental Engineering ConcreteStructures (ACI 350-06),” hereinafter called the code.Emphasis is given to the explanation of provisions that may beunfamiliar to users of the standard. Com

27、ments on specificprovisions are made under the corresponding chapter andsection numbers of the code and commentary.This commentary is not intended to provide a complete histor-ical background concerning the development of the code, noris it intended to provide a detailed summary of the studies andre

28、search data reviewed by the committee in formulating theprovisions of the code. However, references to some of theresearch data are provided for those who wish to study thebackground material in depth.As the name implies, “Code Requirements for Environ-mental Engineering Concrete Structures” may be

29、used aspart of a legally adopted code and, as such, must differ inform and substance from documents that provide detailedspecifications, recommended practice, complete designprocedures, or design aids.The code is intended to cover environmental engineeringconcrete structures, but is not intended to

30、supersede ASTMstandards for precast structures.Requirements more stringent than the code provisions may bedesirable for unusual structures. This code and this commen-tary cannot replace sound engineering knowledge, experience,and judgment.A code for design and construction states the minimumrequirem

31、ents necessary to provide for public health andsafety. ACI 350 is based on this principle. For any structure,the owner or the structural designer may require the qualityof materials and construction to be higher than the minimumrequirements necessary to provide serviceability and toprotect the publi

32、c as stated in the code. Lower standards,however, are not permitted.ACI 350 has no legal status unless it is adopted by governmentbodies having the power to regulate building design andconstruction. Where the code has not been adopted, it mayserve as a reference to good practice.The code provides a

33、means of establishing minimum standardsfor acceptance of design and construction by a legallyappointed building official or his designated representatives.The code and commentary are not intended for use in settlingdisputes between the owner, engineer, architect, contractor, ortheir agents, subcontr

34、actors, material suppliers, or testingagencies. Therefore, the code cannot define the contractresponsibility of each of the parties in usual construction.General references requiring compliance with ACI 350 in thejob specifications should be avoided, since the contractor israrely in a position to ac

35、cept responsibility for designThe commentary discusses some of the considerations of the committee in developing the ACI 350 Code,and its relationship with ACI 318. Emphasis is given to the explanation of provisions that may be unfamiliarto some users of the code. References to much of the research

36、data referred to in preparing the code aregiven for those who wish to study certain requirements in greater detail.The chapter and section numbering of the code are followed throughout the commentary.Among the subjects covered are: permits, drawings and specifications, inspections, materials, concre

37、tequality, mixing and placing, forming, embedded pipes, construction joints, reinforcement details, analysisand design, strength and serviceability, flexural and axial loads, shear and torsion, development of reinforce-ment, slab systems, walls, footings, precast concrete, prestressed concrete, shel

38、l structures, folded platemembers, provisions for seismic design, and an alternate design method in Appendix I.The quality and testing of materials used in the construction are covered by reference to the appropriatestandard specifications. Welding of reinforcement is covered by reference to the app

39、ropriate AWS standard.Criteria for liquid-tightness testing may be found in 350.1.Keywords: Chemical attack; coatings; concrete durability; concrete finishing (fresh concrete); concrete slabs, crack width, and spacing; cracking(fracturing); environmental engineering; inspection; joints (junctions);

42、 aligned in the right column. To further distinguish the Code from the Commentary, the Code hasbeen printed in Helvetica, the same type face in which this paragraph is set.This paragraph is set in Times Roman, and all portions of the text exclusive to the Commentary are printed in this type face.Com

43、mentary section numbers are preceded by an “R” to further distinguish them from Code section numbers.ENVIRONMENTAL STRUCTURES CODE/COMMENTARY 350-3details or construction requirements that depend on a detailedknowledge of the design. Generally, the drawings, speci-fications, and contract documents s

44、hould contain all of thenecessary requirements to ensure compliance with the code.In part, this can be accomplished by reference to specificcode sections in the job specifications. Other ACI publi-cations, such as ACI 301, “Specifications for StructuralConcrete,” are written specifically for use as

45、contractdocuments for construction.Committee 350 recognizes the desirability of standards ofperformance for individual parties involved in the contractdocuments. Available for this purpose are the certificationprograms of the American Concrete Institute, the plant certifi-cation programs of the Prec

46、ast/Prestressed Concrete Institute,the National Ready Mixed Concrete Association, and the qual-ification standards of the American Society of ConcreteConstructors. Also available are “Standard Specification forAgencies Engaged in Construction Inspection and/or Testing”(ASTM E 329) and “Standard Prac

48、 data for design of rect-angular tanks.)“Circular Concrete Tanks Without Prestressing,” PortlandCement Association, Skokie, IL, 1993, 54 pp. (Presents designdata for circular concrete tanks built in or on ground.

The quality of concrete is important, andclose quality control must be performed during construction toobtain impervious concrete.Environmenta
