A hybrid mass damper with active-passive mode switching was developed using a new type of hydraulic actuator. When the hybrid mass damper continues to work against strong winds or earthquakes beyond the capacity of the actuator, active-passive mode switching is carried out due to an excessive drop in the pressure or shortage of the stroke or saturation of the control force. In this paper mode switching due to the stroke shortage and that due to the control force saturation are dealt with. The switching rules and gain-scheduled control laws for both cases were determined by simulation studies. Shaking table tests using a building model with a mass damper model on the roof, showed that mode switching was very effective for the stroke shortage case whereas it was not very effective for the control force saturation case, particularly for slight saturation.
