Design of Machine Foundations on Piles. A practical method for the analysis of pile-supported foundations subjected to dynamic loadings is described. The method uses a single-degree-of-freedom mass-spring-dashpot model of a form similar to that used for shallow foundations to analyze the response of the actual system. The method of analysis uses the concept of an equivalent cantilever, …
