Book Synopsis The Use of Nondestructive Testing Methods for the Condition Assessment of Concrete Bridge Girders by : Richard Cornelius Unruh
Download or read book The Use of Nondestructive Testing Methods for the Condition Assessment of Concrete Bridge Girders written by Richard Cornelius Unruh and published by . This book was released on 2004 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are over 594,000 publicly controlled bridges in the United States. Concrete and pre-stressed concrete bridges account for nearly 50% of the bridges in the US inventory. This proportion is increasing each year, as new bridges tend to be constructed of concrete. This trend makes it vital for engineers to be able to accurately assess the condition of concrete for maintenance and repair decisions. The use of nondestructive testing methods can help reduce the backlog of deficient bridges in two ways. First, these techniques will allow inspectors to get a more accurate view of the condition of a bridge. The second way by which NDT can help is by allowing inspectors to locate damage earlier. This thesis is an attempt to capture the most current ideas for a very specific application of NDT: determining the condition of reinforced concrete bridges overall and bridge girders, in particular. To this end, attention is given to why NDT is needed and what aspects of concrete condition can be addressed with NDT. Some NDT methodologies that are, or may soon be, promising for concrete applications are discussed. Case studies are presented to demonstrate how NDT can be applied to concrete bridge girders and proposals are made for future areas of study and development.

This book was released on 2010-06 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: This authoritative book provides a comprehensive review of the highly important subject of non-destructive evaluation of reinforced concrete structures. Engineers have a range of sophisticated techniques at their disposal to assess the condition of reinforced concrete structures that do not cause material damage and which usually enable the structure to be used while the surveys are carried out. Non-destructive evaluation of the infrastructure also plays a key role in calculating and prioritising where money should be spent on repair or replacement. Providing details of related techniques and case studies, this book offers an overview of how to plan and implement the NDT of reinforced concrete structures.
Book Synopsis Inspection Methods & Techniques to Determine Non Visible Corrosion of Prestressing Strands in Concrete Bridge Components by : Lawrence Harper Jones
Download or read book Inspection Methods & Techniques to Determine Non Visible Corrosion of Prestressing Strands in Concrete Bridge Components written by Lawrence Harper Jones and published by . This book was released on 2010 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: Catastrophic failures of non-composite prestressed precast concrete adjacent-box beam bridges have occurred in several states due to corrosion of the prestressing steel. These failures have highlighted the need to improve methods used to detect corrosion damage and subsequently load rate the damaged members. In light of this, PennDOT initiated a research program aimed at improving inspection techniques through evaluation of off-the-shelf non-destructive testing (NDT) technologies and correlation of surface conditions with non-visible strand corrosion. Funding for the project was provided by the departments of transportation of Pennsylvania (the lead agency), New York, and Illinois. Currently, the inspection of concrete box girder sections relies on visual methods which correlate longitudinal and transverse cracking, spalling, and exposed strands with the rated level of performance of the member. While the visual method provides a qualitative estimate of the amount of damage, the specific location along a strand and the amount of damage to the strands is not clearly defined. As a result, the assessment of the condition of the bridge could in some cases result in an un-conservative or overly-conservative estimate of remaining strength. Furthermore, without a high level of accuracy in locating damage to the strands, remediation and rehabilitation is difficult to accomplish. To improve on the current inspection techniques the visual inspection requirements are revisited through an extensive destructive evaluation study. In addition, NDT methods are evaluated and compared with actual damage present in a group of 40- 50 year old box beams removed from service. The goal of this project is to determine if visual inspection techniques or currently available NDT technologies will allow for accurate identification of non-visible corrosion of prestressing strands.
Book Synopsis The Economic Impact of Implementing Nondestructive Testing of Reinforced Concrete Bridge Decks in Indiana by : Benjamin Taylor
Download or read book The Economic Impact of Implementing Nondestructive Testing of Reinforced Concrete Bridge Decks in Indiana written by Benjamin Taylor and published by . This book was released on 2016-12-31 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The deck is among the most expensive components of a bridge over its lifetime because of the frequent and costly maintenance and rehabilitation required. Currently, the Indiana Department of Transportation (INDOT) performs visual inspections of a bridge deck as the principal means of determining its condition, which enables the inspector to definitively document the surface condition while the unseen condition below the deck surface is left to the inspector's expert judgement. To compensate for this lack of data, INDOT supplements visual inspections with programmatic scheduling for major work actions, which is very effective for INDOT but costly. In this continuing era of funding shortfalls, INDOT commissioned this study to investigate nondestructive testing (NDT) methods to fill their data gap to inform its work action decision. The NDT methods have been shown to accurately locate corrosion and delamination and are a cost-effective alternative. A project level comparison between the NDT methods was performed to show which method, as well as which combination of methods, were the best choices from a cost perspective. A project level analysis of 30 bridge decks was performed, and those costs were compared to the costs of the current INDOT programmatic schedules. Finally, the analysis was expanded to the network level, which included the entire bridge inventory in Indiana. The results of this study indicate that implementing the NDT methods is cost-effective for INDOT at both the project and network levels.

Download or read book NDT Applications for the Assessment of Asphalt Pavements, Plate Thickness, and Steel-grout Coupling written by Yen Chieh Wu and published by . This book was released on 2012 with total page 227 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nondestructive testing (NDT) uses different wave propagation modes to evaluate the internal structure of materials, revealing internal damage such as corrosion and fracturing that cannot be detected by traditional methods. Civil infrastructures are considered high priority assets in Ontario and Canada because of their value, high consequence of failure, and the continual influence of aging effects. Unexpected failure of infrastructure not only costs more than planned replacements but also results in increased safety risks. The in-situ condition assessment of civil infrastructure is critical for the successful implementation of maintenance and safety programs. Therefore, reliable nondestructive methods of inspection are required for the implementation of economical and efficient maintenance and asset management programs. Continuing technological developments in data collection, acquisition equipment, and data processing techniques have provided useful applications of nondestructive methods in many engineering fields. Among the many applications, this research study examines three applications of nondestructive testing in civil engineering: (1) condition assessment of construction joints in asphalt pavements, (2) average thickness evaluation of steel pipes, and (3) void and debonding detection in grouted steel tanks. The study on asphalt focuses on the improvement of the coupling system between the transducers and the asphalt surface, and the development of a new data processing technique to reduce user input and increase the reliability of the condition assessment of longitudinal joints.
Book Synopsis Nondestructive Condition Assessment of a Posted Bridge by :
Download or read book Nondestructive Condition Assessment of a Posted Bridge written by and published by . This book was released on 1997 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are about five hundred steel-truss highway bridges in Ohio, as well as many thousands in the nation, which are more than seventy-five years old. Preservation of aged historic steel-truss bridges first requires a consideration of public safety issues. Bridges with certain structural attributes and materials are well established as having non desirable failure modes, which make them public safety hazards. These should be removed from service with the highest possible priority. If non-technical issues such as historic significance and functional adequacy are favorable, the question then becomes whether a given bridge can be preserved within the available financial and technical resources of the responsible government agency.
Book Synopsis Prestressed Concrete Bridges by : Christian Menn
Download or read book Prestressed Concrete Bridges written by Christian Menn and published by Birkhäuser. This book was released on 2012-12-06 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book was written to make the material presented in my book, Stahlbetonbrucken, accessible to a larger number of engineers throughout the world. A work in English, the logical choice for this task, had been contemplated as Stahlbetonbrucken was still in its earliest stages of preparation. The early success of Stahlbetonbrucken provided significant impetus for the writing of Prestressed Concrete Bridges, which began soon after the publication of its predecessor. The present work is more than a mere translation of Stahlbetonbrucken. Errors in Stahlbetonbrucken that were detected after publication have been corrected. New material on the relation between cracking in concrete and corrosion of reinforce ment, prestressing with unbonded tendons, skew-girder bridges, and cable-stayed bridges has been added. Most importantly, however, the presentation of the material has been extensively reworked to improve clarity and consistency. Prestressed Concrete Bridges can thus be regarded as a thoroughly new and improved edition of its predecessor.
