Abstract
In this work, the study is made upon the dynamic behaviour of isolated foundations supporting vibrating machinery considering the effect of soil- structure interaction. The finite element procedure is used in simulating of the machine foundation for its capability in modeling and its compatibility with the computer software. The foundation is discretized using plate elements having the capability of sustaining forces in three directions as well as bending. The soil- structure interaction is modeled using Winkler type foundation having moduli in three directions. The modeling and analysis are done by the NASTRAN computer software. The effect of the base foundation and the stiffness of isolated springs are considered in the analysis.
