We propose a method to estimate the response of a seismic isolation layer using an accelerometer which is located immediately above base-isolated layer. The method is based on the assumption that seismic isolation structure is excited mainly by its first mode. In this paper, we estimate the displacement response of the isolation layer utilizing a state space expression and a transfer function between response acceleration and a relative displacement. Simulation and experiments results confirmed the feasibility of the proposed method.
