Earthquakes in the United States and elsewhere have demonstrated the vulnerability of older bridges to even moderate earthquakes. Recognizing the need to upgrade the bridge inventory, the Federal Highway Administration (FHWA) began sponsoring research and development in seismic retrofitting in the early 1980's. A set of guidelines was published in 1983 and updated by NCEER with a synthesis of the literature in 1995 (Seismic retrofitting Manual for Highway Bridges FHWA-RD-94-052 May 1995). A short course was held in 1998. The course covered preliminary screening, detailed evaluation, and retrofit measures for highway bridges. In December 2006 the new FHWA retrofit manual (Seismic Retrofitting Manual for Highway Structures: Part 1-Bridges FHWA-HRT-06-032 January 2006) was distributed to all the states. The manual has doubled in length and incorporates over a decade of research by MCEER and the practical experience of Caltrans in retrofitting thousands of bridges. Part 1 is the text for this course and the notebook is intended to update and facilitate the manual's use. The manual recommends performance criteria according to bridge importance and anticipated service life, and seismic hazard level. Minimum recommendations are made for screening, evaluation, and retrofitting according to an assigned Seismic Retrofit Category. Various retrofit strategies are described and a range of related retrofit measures explained, including restrainers, seat extensions, column jackets, footing overlays, and soil remediation. The length of the course is one day. However, references to and materials from prior training developed by the MCEER team and authors and instructors are provided. Topics to be discussed include: Seismic and Geotechnical Hazards; Seismic Retrofit Procedures; Geotechnical Modeling; Seismic Evaluation Methods; Retrofit Details; Geotechnical Retrofit Strategies; methods of Analysis; Retrofit Applications; Design Examples. The course is intended for engineers from Departments of Transportation and consultants who have an interest in seismic retrofitting. Attendees are expected to learn about the behavior of bridges in earthquakes and methods for improving this performance. Emphasis will be given to older bridges typical of the central and eastern US. The pilot course is offered by Bridge technology to provide engineers with practical knowledge about current and emerging technologies and design procedures that will enhance their career skills, while improving the safety of our built environment from earthquakes and other hazards.

The primary objectives of the report are to (1) provide current information on the theory and techniques for seismic analysis of highway bridges, including background material on basic structural dynamics, (2) identify the appropriate criteria necessary to decide if a bridge needs retrofitting and the type of retrofit measures to employ, and (3) demonstrate design details and installation specifications for retrofitting existing highway bridges to minimize earthquake damage. This report is in two volumes: Vol 1 "Earthquake and Structrural Analysis" Vol. 2 "Design Manual". Volume two is a design manual and contains illustrations of various retrofit concepts and specific design procedures which can be applied to existing bridges.

This manual is an interim revision of the Federal Highway Administration (FHWA) publication "Seismic Retrofitting Guidelines for Highway Bridges", which was published in 1983 as report number FHWA/RD-83/007. It describes an evaluation procedure for retrofitting seismically deficient highway bridges and outlines various measures to upgrade these structures. The guidance provided in this manual is comprehensive in nature and nationally applicable to bridges in different seismic zones. It includes a revised preliminary screening procedure; two methods of detailed evaluation (which include the capacity/demand ratio method and the lateral strength method); and expanded sections on retrofit measures for bearings, columns, footings, foundations, and soils. A new section on the application of seismic isolation to bridge retrofit is also included. The manual is termed an interim revision because the subject matter is still evolving at this time.

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.
