Available in PDF, EPUB and Kindle. Book excerpt: Abstract: There are a large number of prestressed concrete box beam bridges in service. Currently there are no satisfactory methods to rehabilitate deteriorated prestressed concrete box beam bridges. The standard operating procedure within government agencies is to monitor the deterioration until it is required to replace the entire superstructure of the bridge. This is not a cost effective solution because many of the box beam bridges have a small number of deteriorated beams. The design of a cost effective rehabilitation of a deteriorated prestressed box beam bridge is presented. Several options were considered, including the use of fiber reinforced polymer (FRP) reinforcement, replacing the superstructure, and replacing only the damaged beams, among others. The most cost effective and technically feasible option was determined and presented. The best solution for the rehabilitation of the prestressed concrete bridge was to remove and replace only the damaged beams. Removal and construction sequencing and details were developed that will prevent damage to adjacent box beams and allow the connection of the new box beams to the existing adjacent beams.

This book was released on 2012-12-06 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evaluation, repair and rehabilitation of bridges are increasingly important topics in the effort to deal with the deteriorating infrastructure. For example, in the United States about 40 percent of the nation's 570,000 bridges are classified, according to the Federal Highway Administra tion's (FHW A) criteria, as deficient and in need of rehabilitation and replacement. In other countries the situation is similar. FHW A estimates the cost of a bridge replacement and reha bilitation program at 50 billion dollars. The major factors that have contributed to the present situation are: the age, inadequate maintenance, increasing load spectra and environmental contamination. The deficient bridges are posted, repaired or replaced. The disposition of bridges involves clear economical and safety implications. To avoid high costs of replacement or repair, the evaluation must accurately reveal the present load carrying capacity of the struc ture and predict loads and any further changes in the capacity (deterioration) in the applicable time span. Accuracy of bridge evaluation can be improved by using the recent developments in bridge diagnostics, structural tests, material tests, structural analysis and probabilistic methods. There is a need for an international exchange of advanced experience to increase the research effi ciency. The Workshop is organized on the premise that the exchange of existing American and European experience in the area of bridge evaluation, repair and rehabilitation is beneficial for both parties involved.

Available in PDF, EPUB and Kindle. Book excerpt: In the last two decades, the rapid deterioration of bridge structures has become a serious technical and economical problem in many countries, including highly developed ones. Therefore, bridge rehabilitation has also become a very essential factor (sometimes even a decisive one) in contemporary bridge engineering. The book covers in synthetic form nearly all the most important problems concerning bridge rehabilitation, such as bridge superstructure and substructure, the typical damage observed in bridges as well as the assessment and evaluation techniques of their technical condition. The book is intended mainly for postgraduate university students. Therefore, all the problems are mostly presented in their physical, chemical and technical as well as economical aspects. The relevant requirements are treated as objective ones, i.e. irrespective of the rules, standards, regulations or guidelines particular to any country. This approach to the subject gives the book a more general character and therefore makes it a useful text for most civil engineering courses./a

This book was released on 1999 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes a technology review, field surveys, and laboratory investigations into the corrosion of prestressed concrete highway bridge elements and conventional repair methods used for these structures. Details of the technology review and field surveys are given in an Interim Report (FHWA-RD-95-041). Subsequent to completion of the field surveys, a laboratory program designed to evaluate corrosion performance of conventional concrete repair materials was initiated. Test specimens were precorroded by application of anodic current while exposed to chloride solutions. In order to study conventional concrete repairs, it was necessary to remove concrete from preselected areas on each purposely corroded test specimen and replace the chloride-contaminated/deteriorated original concrete with repair materials. Materials evaluated included conventional portland cement concrete, latex-modified fiber-reinforced patching mortar, and silica fume concrete containing either organic or inorganic corrosion inhibitors. Specimens where concrete was not removed were used to study the effects of sealers and coating applied on concrete surfaces to mitigate ongoing corrosion. All specimens were exposed for approximately 200 weeks to a 15% solution of sodium chloride after repair. At the conclusion of exposure, patches were removed from repair specimens and the steel and the applied coatings were examined.
