Fryba Ladislav. Vibration of solids and structures under moving loads

Prague: Academia, 1972. — 512 с.The monograph describes in detail the effects of moving loads on elastic and non-elastic solids, elements, structures and elastic continue. This type of loading — varying both in time and space — may be found in transport engineering structures. Modern means of transport require faster and heavier vehicles, while the structures over which they move are becoming more slender and lighter. For this reason the moving loads have a great effect on dynamic stresses in such structures and cause them to vibrate intensively. That is why the present book devotes particular attention to the effects of speed, weight of the vehicle and structure, and of the parameters substantially affecting the dynamic stresses.
The subject matter of the monograph is arranged in 6 Parts. The first Part — Introduction — is followed by Part II, devoted to the discussion of dynamic loading of one-dimensional solids, i.e. beams, continuous beams, frames, arches, strings etc. Part III deals with two-dimensional solids such as rectangular and infinite plates on elastic foundation. Part IV is focussed on stresses in threc-dimensional spaces and Part V is a treatise devoted to special problems, e.g. the effects of variable speed of the load, effects of shear deformations and rotatory inertia, the effect of moving random loads, etc. Part VI contains comprehensive tables of integral transforms and extensive bibliography.
The following types of loads arc considered in tbe book: moving force (constant or variable in time), continuous load, random load, and special loads (such as those produced by vehicles with the inertial effects of their masses). Consideration is given to all types of speed of the load, ranging from subsonic to supersonic. The most important results arc expressed by formulae or diagrams, in some cases these results are also verified experimentally.
The monograph represents a theoretical guide to economic design of new, and prolonged life of old, civil, mechanical and other engineering structures. The theories expounded in it may find application in calculations of dynamic stresses in bridges, rails, sleepers, roadways, airport runways, tunnels, foundations for all types of high- and railways, and space engineering. The monograph may serve research scientists, project engineers, designers and advanced students.
