The MBE combines the Manual for Condition Evaluation of Bridges, Second Edition (2000) and its 2001

17、and 2003 Interim Revisions with the Guide Manual for Condition Evaluation and Load and Resistance Factor Rating (LRFR) of Highway Bridges, First Edition and its 2005 Interim Revisions. Revisions based on approved agenda items from annual Subcommittee meetings in 2007 and 2008 are also incorporated i

18、nto the MBE. The Manual for Bridge Evaluation, First Edition supersedes the Manual for Condition Evaluation of Bridges, Second Edition and any revisions made in previous Interim Revisions. With the 2008 publication of the MBE, the Subcommittee confers archive status on the Manual for Condition Evalu

19、ation of Bridges, the Guide Manual for Condition Evaluation and Load and Resistance Factor Rating (LRFR) of Highway Bridges, and all Interim Revisions of both prior bridge evaluation titles.

Duplication is a violation of applicable law.vi PREFACE Long anticipated and painstakingly developed, The Manual for Bridge Evaluation (MBE) offers assistance to Bridge Owners at all phases of bridge inspection and evaluation. An abbreviated table of co

21、ntents follows this preface. Detailed tables of contents precede Sections 1 through 8. Appendix A includes nine illustrative examples (A1 through A9), previously in the Guide Manual for Condition Evaluation and Load and Resistance Factor Rating (LRFR) of Highway Bridges. To assist users who are alre

22、ady familiar with these examples, the example numbers have been maintained. All examples are rated using the LRFR method. In addition, Examples A1, A2, and A4 are now rated using the ASR and LFR methods. To clarify which rating method is being illustrated, Examples A1, A2, and A4 are divided into Pa

23、rts A through C and their articles are numbered accordingly as follows: Part A, LRFR; Part B, ASR and LFR; and Part C, example summary. For ease of reference, the table of contents for Appendix A includes a summary table of the bridge types, rated members, rating live loads, limit states for evaluat

24、ion, and rating methods, with the starting page number for each example and, in the case of Examples A1, A2, and A4, for each rating method. The typical detailed table of contents follows this summary table. Appendix A includes numerous citations of other AASHTO bridge publications. To save space, t

25、he following shorthand has been adopted: “AASHTO” refers to Standard Specifications for Highway Bridges, 17th Edition, HB-17, “LRFD Design” refers to the current edition of the AASHTO LRFD Bridge Design Specifications, Fourth Edition, LRFDUS-4-M, and “MBE” refers to this publication, The Manual for

26、Bridge Evaluation, Second Edition, MBE-2. MBE includes a CD-ROM with many helpful search features that will be familiar to users of the AASHTO LRFD Bridge Design Specifications CD-ROM. Examples include: Bookmarks to all articles; Links within the text to cited articles, figures, tables, and equation

31、formity in the procedures and policies for determining the physical condition, maintenance needs,and load capacity of the nations highway bridges. This Manual replaces both the 1994 AASHTO Manual for Condition Evaluation of Bridges and the 2003 AASHTO Guide Manual for Condition Evaluation and Load a

32、nd Resistance Factor Rating (LRFR) of Highway Bridges. It serves as a single standard for the evaluation of highway bridges of all types. 1.2SCOPE C1.2 This Manual has been developed to assist BridgeOwners by establishing inspection procedures and evaluation practices that meet the National BridgeIn

33、spection Standards (NBIS). The Manual has been divided into eight Sections, with each Section representing a distinct phase of an overall bridgeinspection and evaluation program. Section 1 contains introductory and backgroundinformation on the maintenance inspection of bridges aswell as definitions

34、of general interest terms. Keycomponents of a comprehensive bridge file are definedin Section 2. The record of each bridge in the fileprovides the foundation against which changes inphysical condition can be measured. Changes incondition are determined by field inspections. A bridgemanagement system

35、 is an effective tool in allocatinglimited resources to bridge related activities. Anoverview of bridge management systems is included inSection 3. The types and frequency of field inspectionsare discussed in Section 4, as are specific inspectiontechniques and requirements. Conditions at a bridge si

36、teor the absence of information from original construction may warrant more elaborate material tests, and varioustesting methods are discussed in Section 5. Section 6 discusses the load rating of bridges and includes theLoad and Resistance Factor method, the Load Factormethod and the Allowable Stres

37、s method. No preferenceis placed on any rating method. The evaluation ofexisting bridges for fatigue is discussed in Section 7. Field load testing is a means of supplementing analyticalprocedures in determining the live-load capacity of abridge and for improving the confidence in theassumptions used

38、 in modeling the bridge. Load testprocedures are described in Section 8. The successful application of this Manual is directly related to the organizational structure established by theBridge Owner. Such a structure should be both effectiveand responsive so that the unique characteristics andspecial

39、 problems of individual bridges are considered indeveloping an appropriate inspection plan and loadcapacity determination. Much of the 2003 AASHTO Guide Manual for Condition Evaluation and Load and Resistance Factor Rating (LRFR) of Highway Bridges has been incorporated and updated in this Manual. S

40、ection 6 of this Manual includes the load ratings provisions of both the 2003 AASHTO Guide Manual for Condition Evaluation and Load and Resistance Factor Rating (LRFR) of Highway Bridges and the 1994 AASHTO Manual for Condition Evaluation of Bridges. 2011 by the American Association of State Highway

Duplication is a violation of applicable law.1-2 THE MANUAL FOR BRIDGE EVALUATION 1.3APPLICABILITY C1.3 The provisions of this Manual apply to all highwaystructures which qualify as bridges in accordance withthe AASHTO definition for a bridge (see

42、Article 1.5). These provisions may be applied to smaller structureswhich do not qualify as bridges. At the discretion of the Bridge Owner, the provisions of this Manual may be applied to highway bridge structures regardless of span or total length of bridge. Federal regulations entitled the National

43、 Bridge Inspection Standards (NBIS) have been promulgated which establish minimum requirements for inspection programs and minimum qualifications for bridge inspection personnel. The NBIS apply to all highway bridges on public roads which are more than 20 ft in length. 1.4QUALITY MEASURES C1.4 To ma

44、intain the accuracy and consistency ofinspections and load ratings, Bridge Owners should implement appropriate quality control and qualityassurance measures. Typical quality control proceduresinclude the use of checklists to ensure uniformity andcompleteness, the review of reports and computations b

45、ya person other than the originating individual, and theperiodic field review of inspection teams and their work.Quality assurance measures include the overall review ofthe inspection and rating program to ascertain that theresults meet or exceed the standards established by theOwner. Quality contro

46、l procedures are intended to maintain the quality of the bridge inspections and load ratings, and are usually performed continuously within the bridge inspection or load rating teams or units. The documented quality control plan may include: Defined quality control roles and responsibilities; Qualif

47、ications for Program Managers, bridge inspection personnel, and load rating personnel,including: o Education and certifications, or education and registration; o Initial training; o Years and type of experience; and o Periodic refresher training. Procedures for review and validation of inspection re

48、ports and data; Procedures for review and validation of load rating calculations and data; and Procedures for identification and resolution of data issues, including errors, omissions, changes, or any combination thereof. Quality assurance procedures are used to verify the adequacy of the quality co

49、ntrol procedures to meet or exceed the standards established by the owning agency.Quality assurance procedures are usually performed independent of the bridge inspection and load rating teams on a sample of their work. The documented quality assurance plan may include: Defined quality assurance roles and responsibilities; Frequency parameters for review of districts or units and bridges; 2011 by the American Association of State Highway and Transporta
