The relative importance of secondary nonlinear effects in soil-structure interaction are investigated by means of the iterative linear method. It is found that the refinement in the analyses, while increasing the cost of computation several times, does not change the dynamic response in the structure to a significant degree. At the same time, an improved algorithm is presented for the computation of the characteristic strain used in the iterative approach.
