Vehicle Bridge Interaction Dynamics




Preface

The commercial operation of the first high-speed (or bullet) train

in 1964 with a speed of 210 km/hr in the Japanese railways connecting

Tokyo and Osaka marked the beginning of a new era in

railway engineering. Since then, high-speed trains with speeds over

200 km/hr or higher have emerged as a competitive tool for intercity

transportation in several countries including Japan, Germany,

France, Italy, Spain, United Kingdom and Sweden. Such a trend

continues to spread in different parts of the world. While Japan

and many European countries have been working on expanding their

high-speed railway networks or improving their existing railway lines,

Asian countries, such as Korea, Taiwan and China, have reached the

stage of planning, constructing, or field-testing their high-speed railway

systems. Undoubtedly, high-speed train will become a key tool

for inter-city passenger transportation, at least in the aforementioned

countries.



Partly enhanced by the rapid expansion of high-speed railway systems,

research on the moving load problems in general, and vehicle–

bridge interactions

in particular, has been booming in the past two

decades. Nevertheless, there is an apparent lack of a timely book

that can adequately address most of the problems encountered in

the design of high-speed railway bridges, which for the reasons stated

In the literature, the term “bridge–vehicle interaction” was also used. It is

realized that such a term was used by those who place more emphasis on the bridge

than on the moving vehicles. In this text, we prefer to use the term “vehicle–

bridge interaction”, since we place equal weights on the dynamic behavior of the

bridge and moving vehicles.
