Because of their structural simplicity, bridges tend to be
particularly vulnerable to damage and even collapse when subjected to
earthquakes or other forms of seismic activity. Recent earthquakes, such
as the ones in Kobe, Japan, and Oakland, California, have led to a
heightened awareness of seismic risk and have revolutionized bridge
design and retrofit philosophies.In Seismic Design and Retrofit
of Bridges, three of the world's top authorities on the subject have
collaborated to produce the most exhaustive reference on seismic bridge
design currently available. Following a detailed examination of the
seismic effects of actual earthquakes on local area bridges, the authors
demonstrate design strategies that will make these and similar
structures optimally resistant to the damaging effects of future seismic
disturbances.
Relying heavily on worldwide research associated
with recent quakes, Seismic Design and Retrofit of Bridges begins with
an in-depth treatment of seismic design philosophy as it applies to
bridges. The authors then describe the various geotechnical
considerations specific to bridge design, such as soil-structure
interaction and traveling wave effects. Subsequent chapters cover
conceptual and actual design of various bridge superstructures, and
modeling and analysis of these structures. As the basis for their
design strategies, the authors' focus is on the widely accepted
capacity design approach, in which particularly vulnerable locations of
potentially inelastic flexural deformation are identified and
strengthened to accommodate a greater degree of stress. The text
illustrates how accurate application of the capacity design philosophy
to the design of new bridges results in structures that can be expected
to survive most earthquakes with only minor, repairable damage. Because
the majority of today's bridges were built before the capacity design
approach was understood, the authors also devote several chapters to the
seismic assessment of existing bridges, with the aim of designing and
implementing retrofit measures to protect them against the damaging
effects of future earthquakes. These retrofitting techniques, though not
considered appropriate in the design of new bridges, are given
considerable emphasis, since they currently offer the best solution for
the preservation of these vital and often historically valued
thoroughfares.
Practical and applications-oriented, Seismic
Design and Retrofit of Bridges is enhanced with over 300 photos and line
drawings to illustrate key concepts and detailed design procedures. As
the only text currently available on the vital topic of seismic bridge
design, it provides an indispensable reference for civil, structural,
and geotechnical engineers, as well as students in related engineering
courses. A state-of-the-art text on earthquake-proof design and retrofit of bridges: Seismic
Design and Retrofit of Bridges fills the urgent need for a
comprehensive and up-to-date text on seismic-ally resistant bridge
design. The authors, all recognized leaders in the field, systematically
cover all aspects of bridge design related to seismic resistance for
both new and existing bridges. A complete overview of current design philosophy for bridges, with related seismic and geotechnical considerations * Coverage of conceptual design constraints and their relationship to current design alternatives * Modeling and analysis of bridge structures * An exhaustive look at common building materials and their response to seismic activity * A hands-on approach to the capacity design process * Use of isolation and dissipation devices in bridge design * Important coverage of seismic assessment and retrofit design of existing bridges.
