VIBRATION CONTROL STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a vibration control structure capable of effectively restraining response vibration up to large vibration generated at a big earthquake time from vibration having small amplitude caused by wind, and a vibration control structure capable of exhibiting a sufficient vibration control effect even on torsional vibration. SOLUTION: A brace 5 or a wall using a passive damper 4 is arranged in a plane of structure composed of columns 2 and beams 3, and an upper part is provided with an active mass damper (an active vibration control device) 11 for restraining a response to vibration of the structure 10 by driving a weight by a driving device.
