Vibration of solids and structures under moving loads

Vibration of solids and structures under moving loads

This book analyses the effects of moving loads on elastic and inelastic solids, elements and parts of structures and on elastic media, namely beams, continuous beams, beams on elastic foundations, rigid-plastic beams and thin-walled beams, frames, arches, strings, plates elastic spaces and half spaces etc. Vibrations in these structures are produced by various types of moving force (loads), such as vehicles with the inertial effects of their masses and by random loads which move with constant or variable speeds along the structure. This type of loading (varying in time and space) may be found in transport engineering structures which need to carry faster and heavier vehicles while the structures over which the vehicles move are becoming slenderer and lighter. The book provides theoretical formulations for the problem, and mathematical solutions for all cases and their application to civil, mechanical, transport, naval and aircraft structures. The extensive and up-to-date bibliography gives a worldwide survey of the problem. The monograph describes ways to prolong the life of existing/older structures and presents a theoretical guide to the economic design of new civil, mechanical and other engineering structures, such as bridges, rails, sleeper, roadways, airport runways, tunnels, foundations for all types of highways and railways, cranes and other transport structures. This book will be of great value to civil, mechanical and transport engineers, researchers, project engineers, designers, postgraduate and undergraduate students and all those interested in structural dynamics.

Dynamics of railway bridges

This book provides a comprehensive survey of the dynamic stresses in railway bridges under moving vehicles and summarizes important theoretical and experimental results which have been obtained from various research programs dealing with European railway bridges. Drawing on the vast experience of the author, and his work for the Office for Research and Experiments of the International Union of Railways, "Dynamics of Railways Bridges": investigates both bridge and moving railway vehicles; summarizes the basic dynamic characteristics of railway bridges - natural frequencies and damping); describes the effect of parameters such as the speed of vehicles, track irregularities etc. on the dynamic behaviour of bridges; and examines the vertical, horizontal longitudinal and horizontal transverse effects - starting and braking forces, lateral impacts etc).With the aid of experimental data obtained from many bridge projects, "Dynamics of Railway Bridges" describes some of the practical solutions and methods that have been applied and will be of benefit and value to civil and railway engineers, researchers - in fact anyone who needs to be aware of the dynamic behaviour of bridges when subjected to moving loads.
