Book Synopsis Extending the Service Life of Existing Bridges by Increasing Their Load Carrying Capacity by : Roland H. Berger
Download or read book Extending the Service Life of Existing Bridges by Increasing Their Load Carrying Capacity written by Roland H. Berger and published by . This book was released on 1978 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: A catalog of bridge deficiencies is developed based on the inspection of over 140 deficient bridges located in Illinois, Florida, Pennsylvania, California, and Tennessee. A classification of structure types is developed for concrete, steel and timber bridges. Deficiencies are related to the structure classification system and a hierarchy of the most common deficiencies established. Techniques presently utilized by state highway departments to correct deficiences are described and evaluated. Several innovative techniques for increasing the load carrying capacity are also described. Utilizing these techniques, increased capacity values are developed. Cost factors are also analyzed and graphic presentations which show the relative merit of each system are presented.
Book Synopsis Response Modification for Enhanced Operation and Safety of Bridges by : Andrew Gastineau
Download or read book Response Modification for Enhanced Operation and Safety of Bridges written by Andrew Gastineau and published by . This book was released on 2011 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report shows that safe extension of the service life of existing bridge structures is possible through bridge health monitoring and structural response modification. To understand bridge health monitoring and structural response modification and control, it is necessary to examine: 1) common bridge vulnerabilities, 2) bridge loading models, 3) response modification devices, and 4) bridge monitoring systems. The efficacy of response modification techniques on a realistic bridge system were demonstrated using the Cedar Avenue Bridge in Minnesota as a specific example. The Cedar Avenue Bridge is a steel tied arch bridge which means that it is fracture critical. Due to the non-redundant nature of a fracture critical bridge, fatigue failure could be catastrophic and is of concern. Previous research has shown that stress concentrations exist at the joints where the hangers and floor beams are attached to the box girder [7]. Using a simulation of response modification on the Cedar Avenue Bridge model, stress ranges have been reduced on these specific details that are of concern. Modeling using a scissor jack and simple damping device has shown that stress ranges can be reduced by approximately 39% which can lead to life extension of as much as 346%.

Book Synopsis Mitigation of Traffic-induced Bridge Vibrations Through Passive and Semi-active Control Devices by : Amy R. Magnuson
Download or read book Mitigation of Traffic-induced Bridge Vibrations Through Passive and Semi-active Control Devices written by Amy R. Magnuson and published by . This book was released on 2011 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many of the U.S. bridges today are reaching or have reached their design life and are beginning to deteriorate and are becoming structurally deficient. Much time, effort, money, and resources go into repairing, rehabilitating, or reconstructing these bridges. Therefore, investigation into valid solutions to extending the safe life of these structures is of utmost importance. A major cause of bridge deterioration is stresses and fatigue induced in the bridge from traffic loading. This paper explores and investigates methods of mitigating traffic-induced bridge vibrations through the integration of control devices to extend the service life of bridges. There are three main classes of structural control devices: passive, semi-active, and active control. Each control scheme has advantages and disadvantages which are discussed in this thesis. To gain a better understanding of both passive and semi-active control strategies, a computer simulation is conducted. The computer simulation allows for a better comparison between passive and semi-active control schemes. The finding from the simulation shows a semi-active control strategy outperforming a passive strategy. The semi-active scheme reduces maximum midspan deflections by 20%, while the passive has a reduction of 12%.
Book Synopsis Structural Motion Engineering by : Jerome Connor
Download or read book Structural Motion Engineering written by Jerome Connor and published by Springer. This book was released on 2014-06-26 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: This innovative volume provides a systematic treatment of the basic concepts and computational procedures for structural motion design and engineering for civil installations. The authors illustrate the application of motion control to a wide spectrum of buildings through many examples. Topics covered include optimal stiffness distributions for building-type structures, the role of damping in controlling motion, tuned mass dampers, base isolation systems, linear control, and nonlinear control. The book's primary objective the satisfaction of motion-related design requirements such as restrictions on displacement and acceleration and seeks the optimal deployment of material stiffness and motion control devices to achieve these design targets as well as satisfy constraints on strength. The book is ideal for practicing engineers and graduate students.

Book Synopsis Cable Vibrations in Cable-stayed Bridges by : Elsa de Sá Caetano (autor.)
Download or read book Cable Vibrations in Cable-stayed Bridges written by Elsa de Sá Caetano (autor.) and published by IABSE. This book was released on 2007 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present book provides a comprehensive survey on the governing phenomena of cable vibration, both associated with direct action of wind and rain: buffeting, vortex-shedding, wake effects, rain-wind vibration; and resulting from the indirect excitation through anchorage oscillation: external and parametric excitation. Methodologies for assessment of the effects of those phenomena are presented and illustrated by practical examples. Control of cable vibrations is then discussed and state-of-art results on the design of passive control devices are presented.

Available in PDF, EPUB and Kindle. Book excerpt: The transformation of vibrations into electric energy through the use of piezoelectric devices is an exciting and rapidly developing area of research with a widening range of applications constantly materialising. With Piezoelectric Energy Harvesting, world-leading researchers provide a timely and comprehensive coverage of the electromechanical modelling and applications of piezoelectric energy harvesters.

Available in PDF, EPUB and Kindle. Book excerpt: The intent of this work is to present an international overview of advances in geotechnical engineering referring to design and construction of road pavements and rail tracks for high-speed trains. It seeks to influence the international pavement and railway engineering community to move away from merely empirical procedures towards a sophisticated approach based primarily on proven theoretical concepts.;The volume covers compaction technology in construction, properties of geomaterials relevant for design and construction, effects of grain crushing, freezing-thawing problems, and embankments for highways and high-speed trains (in-situ tests, modelling, design, monitoring and specifications). It contains 16 contributions including two special lectures: one about high embankments instead of bridges and bridge foundations in embankments, and a second one about impacts on geotechnical engineering from findings of laboratory stress-strain tests on geomaterials.
