The performance of the seesaw active mass damper (SAMD) is considered in this paper. SAMD is constructed such that the support frame of a tuned mass damper is driven like a seesaw by an actuator. In the numerical calculations, transient and seismic responses are compared between the types of SAMD and the tuned mass damper (TMD) by using a single-degree-of-freedom model. Furthermore, in order to examine the feasibility of SAMD, a SAMD was fabricated using the drive mechanism of a ball screw and a DC servomotor, and the control experiment was carried out. As a result, SAMD showed good vibration control performance. Furthermore, the experimental results are in good agreement with the result of numerical calculation.
