揺れは抑えられる。Since the structure 1 and the like have the above-described structure, when the ground 2 moves in the directions C and D in FIG. 2 in the event of an earthquake, the structure body 5 also moves in the directions C and D with respect to the ground 2. Sway. Then, the damping tank 6 provided on the upper portion of the structure body 5 also swings together with the structure body 5 in the directions of arrows C and D, and the liquid 9 inside also swings. The swing cycle of the liquid 9 is
Since the vibration frequency of the structure body 5 is set so as to substantially match the natural frequency of the structure body 5, the vibration energy of the structure body 5 is efficiently absorbed by the swinging of the liquid 9, and the swinging of the structure body 5 is prevented. It can be suppressed.

さを変化させたりすることも、当然可能である。However, in the case where the structure 1 is an oil tank, a warehouse, a water tower, or the like, and when the natural vibration cycle of the structure body 5 changes, in a form corresponding to the change in the natural vibration of the structure body 5,
By selectively driving the actuator 10a shown in FIG.
The partition plates 10 A , 10 B , 10 C , 10 D , and 10 E are moved in the arrow B direction via the rod 10b. Then, the partition plate 10 which has been in the raised state until then moves while being inserted into the tank main body 7, and the tank main body 7 is moved by the partition plate 10 driven and moved.
Is divided into two parts in the left-right direction in the figure by two or more dividing tanks.
It is subdivided into 7a. Then, the rocking cycle of the liquid 9 in each of the divided tanks 7a is changed from the cycle before the division, and is adjusted to substantially match the changed natural frequency of the structure body 5. To be done. In this way, the partition plate 10 is used to selectively drive one or more actuators 10a, and the tank body 7
By partitioning at an appropriate position and forming two or more divided tanks 7a, it is possible to adjust the swing cycle of the damping tank 6 in response to changes in the natural frequency of the structure body 5. It is possible to maximize the damping effect of the damping tank 6. It should be noted that the partition plate 10 is selectively raised by the actuator 10a in the direction of the arrow A to change each of the division tanks 7a into a larger division tank 7a, or a certain division plate 10 is moved up, or another division plate 10 is moved. It is also possible to lower the size of the dividing tank 7a to change the size of the dividing tank 7a.
