This book was released on 2007 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the best alternatives for bridges which need accurate load rating, is through field testing. Presented in this dissertation are two studies on evaluating the performance of bridges based on the results of a diagnostic load test. The first topic is focused on load rating bridges without plans using the results of a diagnostic test. The second topic is focused on utilizing measured displacements from a field test to evaluate the bridge performance.

Available in PDF, EPUB and Kindle. Book excerpt: Bridge Diagnostics, Inc. (BDI) developed hardware and software that are specially designed for performing bridge ratings based on data obtained from physical testing. To evaluate the BDI system, the research team performed diagnostic load tests on seven "typical" bridge structures: three steel-girder bridges with concrete decks, two concrete slab bridges, and two steel-girder bridges with timber decks. In addition, a steel-girder bridge with a concrete deck previously tested and modeled by BDI was investigated for model verification purposes. The tests were performed by attaching strain transducers on the bridges at critical locations to measure strains resulting from truck loading positioned at various locations on the bridge. The field test results were used to develop and validate analytical rating models.

Book Synopsis A Procedure for Load Rating Reinforced Concrete Slab Bridges Without Plans by : Alain Michael Cuaron
Download or read book A Procedure for Load Rating Reinforced Concrete Slab Bridges Without Plans written by Alain Michael Cuaron and published by . This book was released on 2016 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bridges without plans are a problem in the state of New Mexico since standard bridge load rating techniques cannot be used due to the lack of design plans and documentation that contains the required information such as the amount and location of the reinforcement. A research project was conducted for the New Mexico Department of Transportation (NMDOT) to provide an effective method to load rate reinforced concrete slab bridges without plans using both structural analysis and non-destructive experimental techniques. This thesis presents the evaluation of two simple-span and two continuous-span reinforced concrete slab bridges. Bridge 8486 is a simple-span reinforced concrete slab bridge located in Albuquerque, NM. The bridge was built in 1984. According to the most current bridge inspection report for the bridge, the bridge had a satisfactory condition rating for the deck and superstructure and a good condition rating for the substructure. The bottom reinforcement layout was determined using a Hilti Ferroscan along with an AASHTO-based required steel area estimate while the material properties were determined based on the age of the bridge. The final load ratings from an AASHTOWare BrR analysis show that Bridge 8486 is capable of carrying an HS-20 vehicle safely. Bridge 8282 is a simple-span reinforced concrete slab that was built in 1976. The bridge is located in Albuquerque, NM. The bridge has a satisfactory condition rating for the deck and superstructure while the substructure was given a fair condition rating based on the most current bridge inspection report. The bottom reinforcement layout and material properties were estimated similarly to Bridge 8486. The final BrR load ratings show that the bridge has a load carrying capacity that can safely carry an HS-20 vehicle. Bridge 8827 is a three-span continuous reinforced concrete slab bridge. The bridge was built in 1991 in Albuquerque, NM. The deck, superstructure and substructure were given a fair condition rating in the most current bridge inspection report. Like Bridge 8486 and Bridge 8282, the bottom reinforcement was estimated using a Hilti Ferroscan, however, the scanner did not provide enough data to estimate the top reinforcement layout. Therefore, the top reinforcement layout was estimated using a combination of AASHTO, a top to bottom steel area ratio assumption (i.e., steel area for the top of the slab above the pier is 10% larger than the bottom steel area at midspan), and the Hilti Ferroscan results. Based on the final BrR load ratings, the bridge can carry an HS-20 vehicle safely. Bridge 7489 is a two-span continuous reinforced concrete slab bridge. The bridge was built in 1964 in Albuquerque, NM. The bridge had satisfactory condition ratings for the deck, superstructure, and substructure. The bottom and top reinforcement layout were estimated using the Hilti Ferroscan along with the required steel area estimation following AASHTO. The bridge load rating from BrR showed that the bridge could carry an HS-20 vehicle.

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.
