ABSTRACT:
An active seismic response control system includes a variable damping device provided between posts, beams and braces of a structure, wherein the response of the frame is reduced by controlling the variable damping device when an earthquake or strong wind occurs to give a damping force to the frame. The response of the structure is determined by the steps of judging with a computer the optimal damping force or control force to be applied to the structure on the basis of information obtained from sensors in response to the disturbance, and then controlling the coefficient of damping of the variable damping device.
