Highway Vehicle-bridge Coupled Vibrations: Numerical Simulations And Applications


Book Description

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.




Vehicle-bridge Interaction Dynamics


Book Description

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. Besides, some field tests were conducted 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 response 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.

Dynamic Interaction of Train-Bridge Systems in High-Speed Railways


Book Description

This book presents both the fundamental theory and numerical calculations and field experiments used in a range of practical engineering projects. It not only provides theoretical formulations and various solutions, but also offers concrete methods to extend the life of existing bridge structures and presents a guide to the rational design of new bridges, such as high-speed railway bridges and long-span bridges. Further, it offers a reference resource for solving vehicle–structure dynamic interaction problems in the research on and design of all types of highways, railways and other transport structures.

Environmental Vibrations: Prediction, Monitoring, Mitigation and Evaluation


Book Description

Globally there is much interest in environmental vibrations, as caused by all forms of traffic, by construction activities and factory operations, and by other man-made sources. The focus is on prediction, control and mitigation to benefit our quality of life, and also to improve the operation of sensitive machines in high-tech production. The Japanese Geotechnical Society, the Architectural Institute of Japan, the Japanese Society of Civil Engineering and the Chinese Society for Vibration Engineering came together to organise this International Symposium on Environmental Vibrations at Okayama University, from September 20th to September 22nd, 2005. This book contains the proceedings of this meeting, recording the international exchange of experience, knowledge and research presented at the conference. Both invited and submitted papers are included, written by eminent academic professionals and engineering specialists. It includes topical areas of environmental vibrations, as well as referring to expertise and practices in related fields, these include: wave propagation in soils; soil dynamics; soil-structure dynamic interaction; field measurement of environmental vibration; monitoring of environmental vibrations; development of vibration mitigation measures; evaluation of environmental vibrations; effects of vibration on human perception; effects of vibration on high-precision machines. Both the research community and professionals in the field of environmental vibrations will find this an excellent resource.
