15、uctures. Such structures 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

16、 requirements than non-environmental building structures.Loadings include normal dead and live loads and vibrating equipment or hydrodynamic forces. Exposuresinclude concentrated chemicals, alternate wetting and drying, and freezing and thawing of saturatedconcrete. Serviceability requirements inclu

18、ant tochemicals, with 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 318M-02 Build

19、ing Code that areapplicable to environmental engineering concrete structures.Because ACI 350M-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 concretestructures. Thus, it

20、cannot present background details or suggestions for carrying out its requirements orintent. It is the function of the commentary to fill this need.CODE REQUIREMENTS FOR ENVIRONMENTAL ENGINEERING CONCRETE STRUCTURES(ACI 350M-06) AND COMMENTARYREPORTED BY ACI COMMITTEE 350ACI 350M-06 was adopted as a

21、 standard of the American Concrete Instituteon July 3, 2006 to supersede ACI 350M/350RM-01 in accordance with theInstitutes standardization procedure. ACI 350M-06 is a complete metriccompanion to ACI 350-06.ACI Committee Reports, Guides, and Commentaries are intended forguidance in planning, designi

26、e and CommentaryINTRODUCTIONThe code and commentary includes excerpts from ACI 318M-02that are pertinent to ACI 350M. The commentary discusses someof the considerations of Committee ACI 350 in developing “CodeRequirements for Environmental Engineering Concrete Struc-tures (ACI 350M-06),” hereinafter

27、 called the code. Emphasis isgiven to the explanation of provisions that may be unfamiliar tousers of the standard. Comments on specific provisions are madeunder the corresponding chapter and section numbers of the codeand commentary.This commentary is not intended to provide a complete histor-ical

28、background concerning the development of the code, noris it intended to provide a detailed summary of the studies andresearch 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 thebackgroun

29、d material in depth.As the name implies, “Code Requirements for Environ-mental Engineering Concrete Structures” may be used aspart of a legally adopted code and, as such, must differ inform and substance from documents that provide detailedspecifications, recommended practice, complete designprocedu

30、res, or design aids.The code is intended to cover environmental engineeringconcrete structures, but is not intended to supersede ASTMstandards for precast structures.Requirements more stringent than the code provisions may bedesirable for unusual structures. This code and this commen-tary cannot rep

31、lace sound engineering knowledge, experience,and judgment.A code for design and construction states the minimumrequirements necessary to provide for public health andsafety. ACI 350M is based on this principle. For any struc-ture, the owner or the structural designer may require thequality of materi

32、als and construction to be higher than theminimum requirements necessary to provide serviceabilityand to protect the public as stated in the code. Lower stan-dards, however, are not permitted.ACI 350M has no legal status unless it is adopted by govern-ment bodies having the power to regulate buildin

33、g design andconstruction. Where the code has not been adopted, it mayserve as a reference to good practice.The code provides a means of establishing minimum standardsfor acceptance of design and construction by a legallyappointed building official or his designated representatives.The code and comme

34、ntary are not intended for use in settlingdisputes between the owner, engineer, architect, contractor, ortheir agents, subcontractors, material suppliers, or testingagencies. Therefore, the code cannot define the contractresponsibility of each of the parties in usual construction.General references

35、requiring compliance with ACI 350M inthe job specifications should be avoided, since the contractor israrely in a position to accept responsibility for designThe commentary discusses some of the considerations of the committee in developing the ACI 350MCode, and its relationship with ACI 318M. Empha

36、sis is given to the explanation of provisions that may beunfamiliar to some users of the code. References to much of the research data referred to in preparing thecode are given for those who wish to study certain requirements in greater detail.The chapter and section numbering of the code are follo

37、wed throughout the commentary.Among the subjects covered are: permits, drawings and specifications, inspections, materials, concretequality, mixing and placing, forming, embedded pipes, construction joints, reinforcement details, analysisand design, strength and serviceability, flexural and axial lo

38、ads, shear and torsion, development of reinforce-ment, slab systems, walls, footings, precast concrete, prestressed concrete, shell structures, folded platemembers, provisions for seismic design, and an alternate design method in Appendix I.The quality and testing of materials used in the constructi

39、on are covered by reference to the appropriatestandard specifications. Welding of reinforcement is covered by reference to the appropriate AWS standard.Criteria for liquid-tightness testing may be found in 350.1.Keywords: chemical attack; coatings; concrete durability; concrete finishing (fresh conc

To further distinguish the Code from the Commentary, the Code hasbeen printed in Helvetica, the same type face in which this paragraph is se

Generally, the drawings, speci-fications, and contract documents should contain all of thenecessary requirements to ensure compliance with the code.In part, this can be accomplished by reference to specificcode secti

45、ons in the job specifications. Other ACI publi-cations, such as ACI 301M, “Specifications for StructuralConcrete,” are written specifically for use as contractdocuments for construction.Committee 350 recognizes the desirability of standards ofperformance for individual parties involved in the contra
