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
Many more people are coming to live in earthquake-prone areas, especially urban ones. Many such areas contain low-rise, low-cost housing, while little money is available to retrofit the buildings to avoid total collapse and thus potentially save lives. The lack of money, especially in developing countries, is exacerbated by difficulties with administration, implementation and public awareness. The future of modern earthquake engineering will come to be dominated by new kinds of measuring technologies, new materials developed especially for low-rise, low-cost buildings, simpler and thus lower cost options for retrofitting, cost cutting and raising public awareness. The book covers all the areas involved in this complex issue, from the prevention of total building collapse, through improvement techniques, to legal, financial, taxation and social issues. The contributors have all made valuable contributions in their own particular fields; all of them are or have been closely involved with the issues that can arise in seismic zones in any country. The recent research results published here offer invaluable pointers to practicing engineers and administrators, as well as other scientists whose work involves saving the lives and property of the many millions of people who live and work in hazardous buildings.

Book Description
This document contains guidelines for the seismic retrofitting of highway bridges. The guidelines are the recommendations of a team of nationally recognized experts, which includes consulting engineers, academicians, state highway engineers, and federal agency representatives from throughout the United States. The guidelines are comprehensive in nature and embody several new concepts. An extensive commentary documenting the basis for the guidelines and a worked example problem illustrating their use are included. The guidelines include a preliminary screening procedure, methods for evaluating an existing bridge in detail, and potential retrofitting measures for the most common seismic deficiencies. These guidelines utilize many of the concepts presented in the "Seismic Design Guidelines for Highway Bridges" (Report No. FHWA/RD-81/081) and are intended to be used in conjunction with that document.

Book Description
"TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 440, Performance-Based Seismic Bridge Design (PBSD) summarizes the current state of knowledge and practice for PBSD. PBSD is the process that links decision making for facility design with seismic input, facility response, and potential facility damage. The goal of PBSD is to provide decision makers and stakeholders with data that will enable them to allocate resources for construction based on levels of desired seismic performance"--Publisher's description.

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.
