Book excerpt: 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.

Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2009 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much of Utah's population dwells in a seismically active region, and many of the bridges connecting transportation lifelines predate the rigorous seismic design standards that have been developed in the past 10-20 years. Other states in the west have instituted seismic retrofit programs in response to damage to transportation networks in past California earthquakes. In a parallel report, seismic retrofit guidelines were developed for Utah based on the Seismic Retrofitting Manual for Highway Structures published by FHWA. In this report, representative case study bridges are evaluated in detail using the guidelines. The case study evaluations include the following for each bridge: 1- selection and presentation of analysis method, 2- development of numerical model in LARSA 4D and/or additional programs as needed, 3- evaluation of the seismic response of the unretrofitted bridge, 4- design of a possible retrofit scheme. The bridges evaluated include a four-span simply supported prestressed concrete girder bridge, a four-span continuous concrete T-beam, and an eight-span curved steel girder bridge with in-span pin and hanger joints.

A variety of retrofit techniques are presented including column jacketing, cable restrainers, selectively closing pin and hanger joints, and seismic isolation. The varied examples and techniques presented in this report are meant to be representative of assessment and applicable retrofit approaches for many of the bridges in the state inventory that may be seismically deficient.
