Available in PDF, EPUB and Kindle. Book excerpt: Connection plates cross frame diaphragms not rigidly attached to tension flanges can develop fatigue cracking in the unstiffened web gap due to the out-of-plane distortion. This report investigates repair procedures for fatigue damage in the web gap of steel highway bridges. The procedures investigated include drilling holes at crack tips, flame-cutting holes to remove extensively cracked regions, and gouging and rewelding. In addition, rigid attachment retrofits of tight-fit and cut-short connection plate details are examined. The evaluation of these repairs are made by monitoring their implementation on an in-service bridge, laboratory fatigue testing of simulated repairs, and finite element analysis. All three crack repair procedures were found to be viable. However, procedures outlined must be followed to achieve the quality in the repair that will insure continued safe use of the bridge throughout its remaining life. The results indicate that the degree of finish given to the repair is as important as satisfying the prescribed repair criteria.

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.

This book was released on 2014-03-14 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fiber-reinforced polymer (FRP) composites are becoming increasingly popular as a material for rehabilitating aging and damaged structures. Rehabilitation of Metallic Civil Infrastructure Using Fiber-Reinforced Polymer (FRP) Composites explores the use of fiber-reinforced composites for enhancing the stability and extending the life of metallic infrastructure such as bridges. Part I provides an overview of materials and repair, encompassing topics of joining steel to FRP composites, finite element modeling, and durability issues. Part II discusses the use of FRP composites to repair steel components, focusing on thin-walled (hollow) steel sections, steel tension members, and cracked aluminum components. Building on Part II, the third part of the book reviews the fatigue life of strengthened components. Finally, Part IV covers the use of FRP composites to rehabilitate different types of metallic infrastructure, with chapters on bridges, historical metallic structures and other types of metallic infrastructure. Rehabilitation of Metallic Civil Infrastructure Using Fiber-Reinforced Polymer (FRP) Composites represents a standard reference for engineers and designers in infrastructure and fiber-reinforced polymer areas and manufacturers in the infrastructure industry, as well as academics and researchers in the field. Looks at the use of FRP composites to repair components such as hollow steel sections and steel tension members Considers ways of assessing the durability and fatigue life of components Reviews applications of FRP to infrastructure such as steel bridges
