摘要：It is well known that the dynamic response of the structure to an earthquake excitation is affected by the interaction with the foundation and the soil.The expansion of informatics and development of the computer capacities has helped the scientists to develop numerical models for approximate solutions of big variety of problems related to SSI(Soil Structure Interaction).Many of those problems involve domain-coupling.In this paper we built numerical model,based on finite differences and we investigate the accuracy of the numerical model depending upon the size of the square domain around the source.We tested eight different square sizes and we analyzed their accuracy regarding to five different wave periods.The results give recommendations for the implementation of the domain-coupling algorithm.
