Book excerpt: This report presents preliminary results and a detailed plan for an investigation whose objective is to examine the economics and technology of proof testing of highway bridges. Current practice of highway bridge structural evaluation in the United States and New York State is reviewed. It is noted that current codes do not include provisions for proof testing in bridge structural evaluation, and no standard proof-testing procedures are available. A reliability model is introduced to determine the proof loads required for acceptable structural safety. The framework of a proof-testing procedural manual is also outlined. An economic analysis is summarized including relevant costs and benefits.

This book was released on 1995 with total page 84 pages. Available in PDF, EPUB and Kindle. Book excerpt: Because of the limitations of the analytical approach to rating bridges in the current AASHTO specifications, proof-load testing is often a desirable alternative rating method. The study reported here examined the feasibility of a proof-load testing program for New York, addressing both economic and technical aspects. Such a program with clearly defined application areas is found to be cost-effective. Two technical objectives are identified, based on review of current practice elsewhere: 1) prescription of the target proof load, and 2) development of a detailed procedure manual to guide typical proof-load tests. These tasks were completed and the results (including a draft text of the manual) are presented in this report.
Download or read book Guidelines for the Supplementary Load Testing of Bridges written by Institution of Civil Engineers (Great Britain). National Steering Committee for the Load Testing of Bridges and published by Thomas Telford. This book was released on 1998 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bridge authorities in the UK are currently facing a large programme of bridge assessment and strengthening. This has been caused, in part, by the necessity of ensuring that the European Union deadline for allowing 40-tonne lorries on to UK roads can be met. Many bridges have failed theoretical assessments and some bridge owners, frustrated by the fact that many failed structures are apparently in good condition and showing no signs of distress, have resorted to load testing their bridges to try to provide additional information. A National Steering Committee for the Load Testing of Bridges was set up to examine the role of bridge load testing as a tool for assisting the assessment process. The National Steering Committee consists of representatives from all major bridge owners including the Highways Agency, the County Surveyors Society, the London Bridges Engineering Group, Railtrack and the British Waterways Board. It also includes representatives from consulting engineers and universities and has the support of the Institution of Civil Engineers. The overall objective of the National Steering Committee was to produce authoritative guidance on load-testing techniques; which could be used by the practising engineer to determine capacities of existing bridges/structures that are safe, prudent and minimize levels of restriction to the transport infrastructure. In June 1995 the committee appointed Rendel Palmer & Tritton in association with Peter Lindsell & Associates and supported by Professors Bakht, Clark and Harding as consultants to carry out a preliminary study of all the available information on bridge load testing. They were to recommend a detailed methodology which would form the basis of a brief to consultants appointed to produce authoritative guidelines for the load testing of bridges. Their report concluded that there is a place for load testing in the evaluation of bridges and other structures and that load testing is a valid tool for bridge managers. They also concluded that there was enough information and experience available to permit safe and effective guidelines to be written. As a result of the preliminary study the National Steering Committee decided to divide the second stage work and restrict the scope of this document to guidelines for supplementary load testing. Work on proof and proving load testing is being carried out by others under the auspices of the Highways Agency. The guidelines contained in this document were not drafted in a prescriptive form, but seek to provide advice on the appropriate use of supplementary load testing as an aid to assessment by calculation. The guidelines have been written to enable engineers to determine: when it is appropriate to consider the use of supplementary load testing; the level of risk, both public safety and economic, associated with load testing; how to plan and carry out a load test including the level of expertise necessary, the appropriate loading methods and the type and quantity of instrumentation required. In addition, the document is intended to be a source of information on load testing, measuring equipment and specialist techniques that engineers can use for reference.
Download or read book Load Testing of Bridges written by Eva Lantsoght and published by CRC Press. This book was released on 2019-06-26 with total page 429 pages. Available in PDF, EPUB and Kindle. Book excerpt: Load Testing of Bridges, featuring contributions from almost fifty authors from around the world across two interrelated volumes, deals with the practical aspects, the scientific developments, and the international views on the topic of load testing of bridges. Volume 13, Load Testing of Bridges: Proof Load Testing and the Future of Load Testing, focuses first on proof load testing of bridges. It discusses the specific aspects of proof load testing during the preparation, execution, and post-processing of such a test (Part 1). The second part covers the testing of buildings. The third part discusses novel ideas regarding measurement techniques used for load testing. Methods using non-contact sensors, such as photography- and video-based measurement techniques are discussed. The fourth part discusses load testing in the framework of reliability-based decision-making and in the framework of a bridge management program. The final part of the book summarizes the knowledge presented across the two volumes, as well as the remaining open questions for research, and provides practical recommendations for engineers carrying out load tests. This work will be of interest to researchers and academics in the field of civil/structural engineering, practicing engineers and road authorities worldwide.

Download or read book The Art and Science of Dynamic Testing of Highway Bridges written by and published by . This book was released on 1990 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first and second editions of the Ontario Highway Bridge Code contained provisions for dynamic loads in a new format. This format was intended to represent, in an approximate fashion, the mechanics of vehicle and bridge dynamic interaction for the spectrum of both bridges and trucks on Ontario's highway system. Test data available in the literature was generally inadequately defined or detailed to support development of these provisions in a limit states format. A series of major dynamic tests of bridges was conducted in support of development of these dynamic load provisions. This paper reviews test procedures, and recommends standard methods that might be used for dynamic testing of highway bridges. The method of data analysis is of fundamental importance in gaining information from the test that can be useful either for purposes of research, bridge evaluation, or bridge code development. The paper also recommends methods of data analysis, for both bridge dynamic characteristics and bridge dynamic response. For the covering abstract of the Conference see IRRD Abstract No. 807839.
