方向に振動させるように制御することとなる。Since the damping wall 3 and the like have the above-described structure, first, the damping wall 3 is connected to the inner wall surface 2c of the structure 2 by the pin support 3a and the spring 5, as shown in FIG. The distance is held at a predetermined distance L1. In addition, the damping wall 3
It is connected to the inner wall surface 2c of the structure 2 through the spring 5 and the relief valve oil damper 6 so as to be swingable in the left-right direction, that is, in the directions of arrows A and B in the figure, and is pivotally supported on the ground 1. Therefore, when vibration occurs in the structure 2, a vibration state different from the vibration of the structure 2 or a stopped state can be shown by giving a force that damps the vibration of the structure 2. That is, the structure 2 can approach or move away from the damping wall 3 so as to receive the damping force from the relief valve oil damper 6. Therefore, structure 2
The spring 5 and the relief valve oil damper 6 that connect the vibration damping wall 3 to the beams 2f, 2f of the layers 2x, 2y, 2z of the structure 2 are
g and 2h, the structure 2 is vibrated more than the second order as shown by the chain double-dashed line in FIG. 1, and even if each of the beams 2f, 2g, 2h shows different vibration states. , Height positions 2i, 2j of the respective beams 2f, 2g, 2h,
Appropriate damping force can be applied every 2 k. Therefore, when the structure 2 shown in FIG. 1 vibrates in the horizontal direction, that is, in the directions of arrows C and D in FIG. 1 due to an earthquake or the like, the respective vibration sensors 9, 10, 11 provided on the structure 2 The horizontal vibration of each layer 2x, 2y, 2z of the object 2, that is, the horizontal vibration of the first beam 2f, the second beam 2g, and the third beam 2h is detected, and the damper control device 7 is notified to the first beam. Vibration detection signal S1 in 2f, vibration detection signal S in the second beam 2g
2, and outputs the vibration detection signal S3 of the third beam 2h. Then, the damper control device 7, based on the respective vibration detection signals S1, S2, S3, the first beam 2f, the second beam 2g,
The vibration mode of the third beam 2h is instantly recognized, and the relief valve oil dampers 6 corresponding to the respective beams are provided with the respective dampers 6.
Each relief valve oil damper 6 has the inner wall surface 2
The damping characteristic change command S so as to change the damping energy that can most effectively absorb the vibration energy of the vibration generated in the beam 2f, 2g, or 2h provided via c.
4, S5 and S6 are output respectively. Then, each relief valve oil damper 6 causes the damping characteristic change commands S4, S5,
Based on S6, the damping characteristics of the beams 2f, 2g, 2
The damping characteristics are changed so that the vibration energy of the vibration occurring in h can be absorbed most effectively. Here, each of the vibration sensors 9, 10, 11 constantly outputs the vibration detection signals S1, S2, S3 to the damper control device 7 as shown in FIG. 1, and the damper control device 7 outputs the signals S1, S2. , S3, the damping characteristic change commands S4, S5, S6 are constantly output to the respective relief valve oil dampers 6, and the relief valve oil damper 6 outputs the damping characteristic change commands S4, S5, S6 based on the commands S4, S5, S6.
Since the damping characteristic is constantly changed, the relief valve oil damper 6 is configured so that the beams 2f, 2g, 2h of the structure 2 can be changed even if the vibration mode of the beams 2f, 2g, 2h of the structure 2 changes moment by moment.
It is possible to set the damping characteristic that can most effectively absorb the vibration energy of the vibration. Therefore, when the structure 2 vibrates and the first beam 2f, the second beam 2g, or the third beam 2h approaches or moves away from the damping wall 3, the beam 2f or 2g on the inner wall surface 2c or The relief valve oil damper 6 provided between the portion hitting 2h and the damping wall 3 is most effective in damping characteristics corresponding to the vibration mode of the beam 2f or 2g or 2h, that is, the vibration energy of the vibration mode. The beam 2f or 2 in the structure 2 has a damping characteristic that can be absorbed by
The vibration energy of g or 2h can be effectively absorbed, so that the beam 2f or 2g or 2h can be absorbed.
The vibration of can be effectively damped. Therefore, since it is possible to absorb the vibration energy according to the vibration mode of the beams 2f, 2g, or 2h for each of the beams 2f, 2g, 2h, the vibration of the structure 2 is indicated by the chain double-dashed line in FIG. As shown, vibration of the second or higher order, that is, each beam 2f, 2g, 2
Even if h is a vibration showing different vibration modes, the vibrations of the beams 2f, 2g, and 2h can be optimally damped individually, and the entire vibration of the structure 2 can be effectively damped.
When the vibration of the structure 2 is a primary vibration, each relief valve oil damper 6 is connected to each beam 2 in the same manner as above.
Controlling according to the vibration mode of f, 2g, and 2h results in the horizontal direction, that is, the arrow in the figure, in a manner that the damping wall 3 is made to follow so as to give an appropriate damping force to the structure 2. A, B
It will be controlled so as to vibrate in the direction.
