CONTROLLER FOR ADDITIONAL MASS TYPE DAMPING DEVICE AND DAMPING CONTROLLER INCLUDING THE SAME AND THE DAMPING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To display the earthquake-damping effect of an earthquake-damping device from small-to-medium sized disturbance to a great earthquake without expanding the mounting area of the additional mass type earthquake-damping device. SOLUTION: The vibration reducing function of earthquake-damping device 2 itself is displayed up to the vibrations of a fixed quantity or less of amplitude of the weight 21 of the earthquake-damping device 2, and impact force at the time of a collision is utilized as controlling force while limiting a fixed quantity or more of relative displacement of the weight 21 to the structure 1 by making the weight 21 collide with a collision plate 31 connected to the structure 1 when the weight 21 is vibrated in amplitude exceeding a fixed quantity or less of amplitude.
