In this paper, the effective seismic input at strong earthquakes to the seismic design building and to the base-isolated building in Kanagawa University is evaluated. The effective seismic input based on seismic records is compared with the simple evaluation formula. Moreover, the effective seismic input on FEM analyses of base isolated building models is evaluated about the case of various response levels. As a result, in both of the structures, the input loss effect is confirmed in the low natural periods. Furthermore, the analytical results of base-isolated building models show the influence of inertia interaction in the case of small responses.
