VIBRATION CONTROL DEVICE FOR STRUCTURE

PROBLEM TO BE SOLVED: To provide a vibration control device for a structure having a large degree of freedom of design and reducing the number of parts and a construction cost. SOLUTION: A rigid wall 12 is arranged in a frame 44 and supported by arm plates 14 so as to be swingable in the frame 44. W...

Summary:PROBLEM TO BE SOLVED: To provide a vibration control device for a structure having a large degree of freedom of design and reducing the number of parts and a construction cost. SOLUTION: A rigid wall 12 is arranged in a frame 44 and supported by arm plates 14 so as to be swingable in the frame 44. When external force such as an earthquake is applied to the frame 44 to deform the frame 44, the frame 44 and the rigid wall 12 relatively move. A rubber column 26 is loaded between the rigid wall 12 and a column 36, and when the frame 44 and the rigid wall 12 relatively move, the rubber column 26 is deformed to exhibit damping force to absorb the vibrational energy of the frame 44. The arm plates 14 support the load of the rigid wall 12 without applying excessive stress that pulls the rubber column 26 downward, so that the rubber column 26 exhibits sufficient vibration control effect. The rubber column 26 is used and required only to stick the side faces of the rubber column 26 to the rigid wall 12 and the column 26 with an adhesive, so that construction is easy, and a construction period can be shortened.
