With the aid of currently available finite element method results, an approximate analytical solution is developed for the effective seismic motions of cylindrical embedded rigid foundations having the two embedment cases as follows: Case 1; embedded in a viscoelastic surface layer with the foundation base resting on a much stiffer bedrock, Case 2; embedded in a viscoelastic surface layer with the foundation base resting within the surface layer. The characteristics of the solution are compared with the results of the laboratory tests by shaking table and also with the responses observed at an actual embedded foundation during an earthquake, where the original data were available by other investigators. It is found from the comparisons that the solution developed in this paper well agrees with the experimental and observed data.
