ANALYSIS FOR DESIGN OF A MACHINE FOUNDATION-A CRITICAL STUDY

Abstract

or the design of machine foundations, the resonant frequency or r8atural frequency of the foundation - soil system and the L an`plitued fo vibration must be detrermined. A number of empirical d theortical. methods are available to detrmine the dynamic rksoonse of machine foundations. out of these Two main approaches to\this problem have been followed. The first approach is basedon a /linear e1astikc weight less spring theory ( BARKAN'S APPROACH 1962) and second involves dynamic response of a footing resting on the surface of an elastic solid. Based upon theory, simplified Elastic half space analogs have been established by r3ut superiority of one approach over the other is to he invstigated.
