Design of foundation subjected to vibratory loads

Includes bibliographical references (pages 149-150)Vibration developed by operating machinery produces several effects which must be considered in the design of the foundation. However, for a vibration analysis it is necessary to possess a clear understanding of the fundamentals of theory of vibration, modeling techniques, soil dynamics, and in some cases, the application of computer programs in the selection of the foundation geometry. The usual procedure is to establish a mathematical model of the real\ud machine foundation in order to apply the theory of vibrations. Furthermore, the design requires certain design conditions and requirements such as machine properties, soil parameters, and environmental requirements. Machine properties usually are given by the manufacturer and also the unbalanced forces generated by machine are known. Chapter 3 has outlined the several machine parameters required for design.\ud Geotechnical consultant shall obtain all necessary soil parameters that would affect in determining the interaction of soil and foundation. These parameters have been outlined in Chapter 3 for proper evaluation of soil resistance. These geotechnical considerations have been carefully reviewed in this project
