Book Description
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.

Book Description
The Loma Prieta earthquake struck the San Francisco area on October 17, 1989, causing 63 deaths and $10 billion worth of damage. This book reviews existing research on the Loma Prieta quake and draws from it practical lessons that could be applied to other earthquake-prone areas of the country. The volume contains seven keynote papers presented at a symposium on the earthquake and includes an overview written by the committee offering recommendations to improve seismic safety and earthquake awareness in parts of the country susceptible to earthquakes.

Book Description
This report presents the results of the second phase of a comprehensive analytical study on the seismic response of highway bridges in New Jersey. Most bridges in New Jersey are multi-span simply supported (MSSS) where due to impact at the joints the seismic response is highly nonlinear. Therefore, detailed seismic analysis of essential bridges should employ nonlinear computer models that consider the important behavioral characteristics. Among these are: behavior of steel bearings, impact between adjacent spans and between the end-span and the abutment, soil-structure interaction, frictional characteristics following bearing failure, plastic hinges and/or shear failure at the columns, and combined effect of horizontal and transverse ground motion excitations. In light of these, the overall objective of this phase of the study was to evaluate the nonlinear seismic response of actual bridges with emphasis on soil-structure interaction and three-dimensional effect of ground motion. Furthermore, capacity/demand ratios for various components were determined based on the Federal Highway Administration's seismic retrofitting manual for highway bridges.

Book Description
Covers seismic design for typical bridge types and applies to non-critical and non-essential bridges. Approved as an alternate to the seismic provisions in the AASHTO LRFD Bridge Design Specifications. Differs from the current procedures in the LRFD Specifications in the use of displacement-based design procedures, instead of the traditional force-based "R-Factor" method. Includes detailed guidance and commentary on earthquake resisting elements and systems, global design strategies, demand modeling, capacity calculation, and liquefaction effects. Capacity design procedures underpin the Guide Specifications' methodology; includes prescriptive detailing for plastic hinging regions and design requirements for capacity protection of those elements that should not experience damage.

Book Description
Over 140 experts, 14 countries, and 89 chapters are represented in the second edition of the Bridge Engineering Handbook. This extensive collection provides detailed information on bridge engineering, and thoroughly explains the concepts and practical applications surrounding the subject, and also highlights bridges from around the world. This second edition of the bestselling Bridge Engineering Handbook covers virtually all the information an engineer would need to know about any type of bridge-from planning to construction to maintenance. It contains more than 2,500 tables, charts, and illustrations in a practical, ready-to-use format. An abundance of worked-out examples gives readers numerous practical step-by-step design procedures. Special attention is given to rehabilitation, retrofit, and maintenance. Coverage also includes seismic design and building materials. Thoroughly revised and updated, this second edition contains 26 new chapters.

Book Description
Bridge structures can give the impression that they are rather simple structural systems, whose seismic responses can be easily predicted. On the contrary, however, many bridges did not perform well in recent earthquakes, showing a need for increased research to understand various potential problems and collapse mechanisms. Indeed, progress has been made lately in design and assessment procedures around the world, and consequently many practices have changed. In this context, the objective of fib Bulletin 39 is to present, discuss and critically compare structural solutions for bridge seismic design and retrofit that have been developed and are now used all over the world, ten years after the publication of the last comprehensive manual on the subject. It is the result of the work of an international team of experts that collaborated intensively for over three years. The first four chapters of the Bulletin present a regional review of design choices, compare and discuss international design practices, and indicate their relative merits and potential problems. Current developments are treated in the next three chapters, with particular emphasis on design for enhanced damage control, for spatial variation of ground motion and for fault crossing. The last part presents a summary of current issues related to existing bridges. Extensive technical developments have been taking place in the last two decades with the goal of making bridges an important transportation infrastructure with limited damage during earthquakes. Realising this goal depends on regional seismicity, transportation systems, seismic performance goals, local cultures, and a wide range of design and construction practices, which are presented and discussed in this Bulletin.
