Book Description
The problem of environmental vibrations induced by moving traffic loads, is today increasingly one of the fundamental problems to be solved in traffic line planning and design, because they not only influence the living and working of human beings, but also make many high-tech projects unable to work normally. Since the effects of various transportation sources are different, and soil properties play a critical role in the propagation of vibrations, the problem of environmental vibrations is very complex. This book contains the research of the authors via fundamental theories, numerical simulations and field experiments. The main contents include the basic theory and analysis approaches in traffic-induced environmental vibrations, prediction and mitigation through ballast mats of rail traffic induced track-ground vibrations, railway traffic induced ground vibration and its prediction approaches, numerical modeling of vibrations induced by rail traffic in tunnels, investigation of train-induced ground vibrations using FEM and field experiments, human induced vibrations of pedestrian bridges and their prevention, prediction of environmental vibration from underground trains, numerical evaluation on train-induced ground vibration around high-speed railway viaducts, vibration isolation by ground barriers, environmental vibration induced by elevated railway traffic, and train induced vibration in elevated railway stations.

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.

Book Description
Many of the U.S. bridges today are reaching or have reached their design life and are beginning to deteriorate and are becoming structurally deficient. Much time, effort, money, and resources go into repairing, rehabilitating, or reconstructing these bridges. Therefore, investigation into valid solutions to extending the safe life of these structures is of utmost importance. A major cause of bridge deterioration is stresses and fatigue induced in the bridge from traffic loading. This paper explores and investigates methods of mitigating traffic-induced bridge vibrations through the integration of control devices to extend the service life of bridges. There are three main classes of structural control devices: passive, semi-active, and active control. Each control scheme has advantages and disadvantages which are discussed in this thesis. To gain a better understanding of both passive and semi-active control strategies, a computer simulation is conducted. The computer simulation allows for a better comparison between passive and semi-active control schemes. The finding from the simulation shows a semi-active control strategy outperforming a passive strategy. The semi-active scheme reduces maximum midspan deflections by 20%, while the passive has a reduction of 12%.
