The shaking table test of a soil-structure interaction system under hard soil conditions (with an average shear wave velocity of more than 153 m/s) is briefly presented in this paper, and the soil dynamic characteristics, including the shear moduli and damping ratio, are identified using the acceleration results of the test. Based on the identification results of the soil, a three-dimensional finite element analysis of the shaking table test was conducted using the ANSYS program. The surface-to-surface contact element was taken into consideration for the nonlinearity of the interface state of the soil-pile, and an equivalent linear model was used for the soil behavior. By comparing the results of the finite element analysis with the data obtained from the shaking table test, a computational model was validated.
