Abstract
A safety monitoring device is provided for the use in an active seismic response and wind control system for exerting a control force, which restrains the vibration of a structure due to disturbances such as earthquake and wind, from an actuator in response to the above vibration. The safety monitoring device measures the work done of a seismic response control force and judges the work done of the seismic response control force to be positive or negative, so that whether or not the seismic response control is properly carried out by the actuator is judged. If any abnormality is found, a stop signal or the like is generated to stop the seismic response and wind control system, whereby the safety of the structure is ensured.
