Описание: The commercial operation of the bullet train in 1964 in Japan marked the beginning of a new era for high-speed railways. Because of the huge amount of
kinetic energy carried at high speeds, a train may interact significantly with the bridge and even resonate with it under certain circumstances. Equally important is the riding comfort of the
train cars, which relates closely to the maneuverability of the train during its passage over the bridge at high speeds.
This book is unique in that it is devoted entirely to the
interaction between the supporting bridges and moving trains, the so-called vehicle-bridge interaction (VBI). Finite element procedures have been developed to treat interaction
problems of various complexities, while the analytical solutions established for some typical problems are helpful for identifying the key parameters involved.
esides, some field tests were coducted to verify the theories established.
This book provides an up-to-date coverage of research conducted on various aspects of the VBI
problems. Using the series of VBI elements derived, the authors study a number of frontier problems, including the impact response of bridges with elastic bearings, the dynamic
respose of curved beam to moving centrifugal forces, the stability and derailment of trains moving over bridges shaken by earthquakes, the impact response of two trains crossing on a
bridge, the steady-state response of trains moving over elevated bridges, and so on.

Captures Current Developments in Bridge Design and Maintenance
Recent research in bridge design and maintenance has focused on the serviceability problems of older bridges with aging joints. The favored solution of integral construction and design has produced bridges with fewer joints and bearings that require less maintenance and deliver increased durability. Bridge Deck Analysis, Second Edition outlines this growing development, and covers the structural analysis of most common bridge forms. It introduces reliability analysis, an emergent method that allows bridge engineers to determine risk when maintaining older or damaged bridges.
Explains the Background Theory along with Practical Tools
This book includes practical examples of everyday problems in bridge engineering, and presents real-life examples of the application of reliability analysis. The authors show how reliability analysis can determine structural safety even for bridges which have failed a deterministic assessment. They also update other chapters to reflect the most current advancements towards more sophisticated analysis, and the more widespread use of finite element software.
What's New in this Edition:
Incorporates new research on soil-structure interaction
A new section with examples of how to analyze for the effects of creep
Greatly expands the sections on 3-D brick finite elements
Now consistent with both Eurocodes and AASHTO standards
An appropriate resource for senior undergraduates taking an advanced course on bridge engineering, Bridge Deck Analysis is also suitable for practicing engineers, and other professionals involved in the development of bridge design.

Описание: Vehicle-bridge interaction happens all the time on roadway bridges and this interaction performance carries much useful information. On one hand, while vehicles are traditionally viewed as loads for bridges, they can also be deemed as sensors for bridges' structural response. On the other hand, while bridges are traditionally viewed as carriers for vehicle weight, they can also be deemed as scales that can weigh the vehicle loads. Based on these observations, a broad area of studies based on the vehicle-bridge interaction have been conducted in the authors' research group. Understanding the vehicle and bridge interaction can help develop strategies for bridge condition assessment, bridge design, and bridge maintenance, as well as develop insight for new research needs.This book documents fundamental knowledge, new developments, and state-of-the-art applications related to vehicle-bridge interactions. It thus provides useful information for graduate students and researchers and therefore straddles the gap between theoretical research and practical applications.
