    • PROBLEM TO BE SOLVED: To reduce vibrations of a frame by a vibration control device of the frame which suppresses the vibrations of the frame, regarding a clean room which has the vibration control device installed on a floor section. SOLUTION: In the vibration control device 10 of the frame, a girder 12 is laid between columns 14. The end of the girder 12 is joined to the column 14, and a beam-column joint 28 is formed. A working member 30 for making an excitation force act on the girder 12 is mounted near the beam-column joint 28 by using the column 14 as a reaction receiver. The working member 30 comprises a piezoelectric element 16, a beam-side fixing implement 18, the axis line of which agrees with the displacement axis Z1 of the piezoelectric element 16, and a column-side fixing implement 20. In this case, a triangle is formed of the working member 30, the girder 12 and the column 14. A vibration sensor 22 is attached to the girder 12, and the vibrations of the girder 12 are detected and output to a controller 24. The controller 24 generates a vibration control waveform for canceling a vibrational waveform, and outputs it to a driver 26; and the driver 26 generates voltage output corresponding to the vibration control waveform, and outputs it to the piezoelectric element 16. The piezoelectric element 16 is expanded/contracted depending on the vibration control waveform, so as to make the excitation force act on the girder 12. COPYRIGHT: (C)2010,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a vibration control device-adjusting method which facilitates adjustment of a natural frequency of a vibration control device when it is mounted on a slab of a building construction, and to provide the vibration control device and a building floor structure. SOLUTION: A TMD (tuned mass damper) 100 or the vibration control device has a viscoelastic body 104 which is directly or indirectly mounted on an upper surface or a lower surface of the floor slab 16, and a steel plate 102 mounted on the viscoelastic body 104. Then, the natural frequency of the TMD 100 is matched with the natural frequency of the floor slab 16 by changing a size of the viscoelastic body 104 and changing a mounting area of the same. Thus, only by cutting the viscoelastic body 104, for instance, synchronization between the natural frequency of the TMD 100 and the natural frequency of the floor slab 16 is achieved, and therefore preparation of a single type of the viscoelastic body 104 and a single type of the steel plate 102 is sufficient, which leads to good utilization efficiency. Further, only by changing the size of the viscoelastic body 104, the natural frequency of the TMD 100 can be adjusted, which facilitates mounting of the TMD. COPYRIGHT: (C)2009,JPO&INPIT
