This book was released on 2012-04-17 with total page 233 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book focuses on the use of inelastic analysis methods for the seismic assessment and design of bridges, for which the work carried out so far, albeit interesting and useful, is nevertheless clearly less than that for buildings. Although some valuable literature on the subject is currently available, the most advanced inelastic analysis methods that emerged during the last decade are currently found only in the specialised research-oriented literature, such as technical journals and conference proceedings. Hence the key objective of this book is two-fold, first to present all important methods belonging to the aforementioned category in a uniform and sufficient for their understanding and implementation length, and to provide also a critical perspective on them by including selected case-studies wherein more than one methods are applied to a specific bridge and by offering some critical comments on the limitations of the individual methods and on their relative efficiency. The book should be a valuable tool for both researchers and practicing engineers dealing with seismic design and assessment of bridges, by both making the methods and the analytical tools available for their implementation, and by assisting them to select the method that best suits the individual bridge projects that each engineer and/or researcher faces.

Available in PDF, EPUB and Kindle. Book excerpt: Because of their structural simplicity, bridges tend to beparticularly vulnerable to damage and even collapse when subjectedto earthquakes or other forms of seismic activity. Recentearthquakes, such as the ones in Kobe, Japan, and Oakland,California, have led to a heightened awareness of seismic risk andhave revolutionized bridge design and retrofit philosophies. In Seismic Design and Retrofit of Bridges, three of the world's topauthorities on the subject have collaborated to produce the mostexhaustive reference on seismic bridge design currently available.Following a detailed examination of the seismic effects of actualearthquakes on local area bridges, the authors demonstrate designstrategies that will make these and similar structures optimallyresistant to the damaging effects of future seismicdisturbances. Relying heavily on worldwide research associated with recentquakes, Seismic Design and Retrofit of Bridges begins with anin-depth treatment of seismic design philosophy as it applies tobridges. The authors then describe the various geotechnicalconsiderations specific to bridge design, such as soil-structureinteraction and traveling wave effects. Subsequent chapters coverconceptual and actual design of various bridge superstructures, andmodeling and analysis of these structures. As the basis for their design strategies, the authors' focus is onthe widely accepted capacity design approach, in which particularlyvulnerable locations of potentially inelastic flexural deformationare identified and strengthened to accommodate a greater degree ofstress. The text illustrates how accurate application of thecapacity design philosophy to the design of new bridges results instructures that can be expected to survive most earthquakes withonly minor, repairable damage. Because the majority of today's bridges were built before thecapacity design approach was understood, the authors also devoteseveral chapters to the seismic assessment of existing bridges,with the aim of designing and implementing retrofit measures toprotect them against the damaging effects of future earthquakes.These retrofitting techniques, though not considered appropriate inthe design of new bridges, are given considerable emphasis, sincethey currently offer the best solution for the preservation ofthese vital and often historically valued thoroughfares. Practical and applications-oriented, Seismic Design and Retrofit ofBridges is enhanced with over 300 photos and line drawings toillustrate key concepts and detailed design procedures. As the onlytext currently available on the vital topic of seismic bridgedesign, it provides an indispensable reference for civil,structural, and geotechnical engineers, as well as students inrelated engineering courses. A state-of-the-art text on earthquake-proof design and retrofit ofbridges Seismic Design and Retrofit of Bridges fills the urgent need for acomprehensive and up-to-date text on seismic-ally resistant bridgedesign.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this research is to evaluate the effectiveness of three different displacement-based methods for seismic design of ordinary standard bridges. Two bridges previously designed by the Tennessee Department of Transportation (TDOT) engineers following the American Association of State Highway and Transportation Officials (AASHTO) Guide Specifications for LRFD Seismic Bridge Design are selected and investigated in this study. Two different support conditions are considered, one employing seat-type abutments with rigid bent foundations; and the second employing stub wall abutment with flexible bent foundations (Nonlinear Spring Support Configuration). In addition to the AASHTO Specifications, the analysis methods include the capacity-demand-diagram method, as an inelastic demand Capacity Demand Method (CSM), and Federal Emergency Management Agency (FEMA) 440 Procedure C as an equivalent linearization CSM. Pushover analysis methods are used to construct the capacity diagram of the system. Furthermore, the usability of the three most widely used software programs (SAP2000, ADINA, and OpenSees) for performing the displacement-based seismic analysis is studied.This research will provide TDOT engineers with the necessary information on which procedure is the best approach to use for design of highway bridges. Also, it provides information on how well previously designed bridges response when analyzed with the new displacement-based procedures. And finally, it will provide the TDOT engineers with information on capabilities and limitations of various software packages.

This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many existing bridges, especially those built before 1970, were designed with minimum or no seismic considerations. Past experience has shown that such bridges are very vulnerable when subjected to moderate and strong earthquake motions. This was illustrated during the 1989 Loma Prieta, the 1994 Northridge, and the 1995 Kobe earthquakes, when many existing bridge collapsed or were severely damaged. Such a poor performance of the bridges was attributed primarily to the fact that the seismic effects were underestimated in the pre-1970's design practice. In Ottawa region, a great expansion of highway bridges occurred in the 1950's to 1970's, before modern bridge design codes were developed. Statistics show that the number of existing bridges designed according to substandard seismic codes is significantly larger than the number of new, well-designed bridges. Given this, it is essential to develop methods for evaluation and retrofit of existing bridges in order to reduce the risk from seismic actions. In this study, seismic evaluation was conducted to eight bridges located in the Ottawa region and designed according to the pre-1970's bridge codes. In addition, one new bridge, built 1994, was analyzed and was used as a reference case for comparing the performance of older and new bridges. Inelastic models were developed for each bridge and nonlinear dynamic analyses were conducted by using excitation motions compatible with the design spectrum for Ottawa, prescribed by the latest Canadian national code for bridge design. The performance of the bridges was assessed by analyzing the responses represented by curvature ductilities, shear demands, and lateral drifts. The results indicated that the performance of most of the selected bridges is acceptable for the seismic excitations used in this study.
