In this paper, seismic behaviors of high ductility structures including dynamic soil-structure interaction are estimated through numerical simulations. Transfer functions are defined on soil-foundation boundary around sway and rocking motions. The following parameters are selected out among various properties of interaction system to investigate response behavior properly; ductility factors and natural periods in upper structures as well as shear wave velocities in soil ground. Response measurement is arrayed in yield shear force, earthquake input energy for upper structures, radiation damping energy and cumulative plastic deformation under earthquake motion. As a result, in high ductility structures, effect of dynamic soil-structure interaction is assured as well as ordinary ductility structures.
