However, as shown in FIG.
In the case of the vibration damping support structure shown in Fig. 3, any vibration damping structure operates only during a large earthquake to absorb vibration energy and suppress vibration, but for relatively small vibration such as wind vibration, steel materials, friction dampers, etc. With a hysteresis-type damper that does not operate unless a large force acts, such as, no vibration damping effect occurs. By the way, if such a small vibration continues, there is a problem that the material is fatigued and the strength is deteriorated in the case of a structure, and the habitability in the building is further deteriorated in the case of a high-rise building. .

According to such a structure, the viscous damper, of the two types of dampers provided so as to be able to operate in parallel between the structures or places where relative displacement occurs during vibration, is the initial stage generated between the two structures. It mainly acts to damp small vibrations.
The other hysteresis damper absorbs vibration energy by utilizing a large resistance force due to elastic-plastic deformation or frictional force of a member when the clearance exceeds a set clearance, and suppresses vibration. By linking the actions of both of the above, it is possible to maintain a continuous vibration damping action for both small vibrations and large vibrations occurring in the structure and to damp the vibrations of the structure. It also allows the structure to have a lightweight structure.

First, in FIG. 1, reference numerals 1 and 2 denote a high-frequency structure, a low-frequency structure, and a one-structure 1 which generate relative displacement during vibration in a boiler, a tower-type chimney, or a high-rise building. Rigid convex portions 4 provided on the side, 4 are rigid supporting portions that project from the other structure 2 so as to face the side portions of the convex portions 3,
Reference numeral 5 is an oil damper, that is, a viscous damper, interposed between the convex portion 3 and the support portion 4, and 6 is an elasto-plastic material such as a steel material or a lead material 7 having a member cross section set by projecting at the end of the convex portion 3. An elasto-plastic damper, that is, a hysteresis-type damper, comprising 7 and rigid stoppers 8 and 8 projecting from the other structure 2 so as to face each other with a clearance set on both sides of the elasto-plastic material 7. The oil damper 5 and the elasto-plastic damper 6 are respectively installed in two directions at right angles in the horizontal plane so as to operate together in parallel with the vibration of the structure 1 or 2 as shown in the figure.

In the first embodiment shown in FIG. 1, now,
When the structure 1 moves to the right as shown by the arrow, its vibration is damped by the viscous resistance of the oil damper 5 with the structure 2 as a support. The oil damper 5 also flexes due to viscous resistance even with large vibrations of the structure, but is less effective in suppressing large vibrations. When the vibration of the structure progresses to the right, the elasto-plastic material 7 comes into contact with the stopper 8 and bends as shown by the broken line, and the resistance force at the time of deformation absorbs the vibration of the structure 1 and suppresses the vibration. It exerts a strong damping force. That is, the oil damper 5 and the elasto-plastic damper 6 act simultaneously at the same time, and this action works alternately on the left and right,
Both the small vibration and the large vibration of the relative displacement vibration generated in the structure 1 can be simultaneously attenuated, and the vibration of the structure can be suppressed.

Next, in a second embodiment shown in FIG. 2, in the structure shown in FIG. 1, an elasto-plastic material 7 is attached to the end of the convex portion 3 on the structure 1 side.
In place of the friction cylinder 17, a hysteresis type damper is used, and the friction damper 16 is configured by providing stoppers 8 on the structures 2 facing each other with a clearance set on both sides of the rod end of the friction cylinder 17. ing.
The friction cylinder 17 is well known, for example, as shown in FIGS.
As shown in FIG. 5, the rod 12 that is in contact with the friction member 11 is slidably provided on the inner surface of the cylindrical body 10, and when the rod 12 is pushed to the left or right in contact with the stopper 8, the friction member 11 is acted by the action of the wedge member 13. A strong frictional resistance is generated between the inner surface of the cylindrical body 10 and the inner surface of the cylindrical body 10. As a result, in FIG.
When the convex portion 3 of the structure 1 vibrates to the right, the rod 12 moves together with the tubular body 10, and the end of the rod 12 contacts the stopper 8 and is pushed leftward, so that the wedge member 13 acts to cause friction with the friction member 11. It is pressed against the inner surface of the cylindrical body 10 to generate a strong frictional force and damp the vibration. The same applies to the opposite direction. Therefore, also in the embodiment of FIG. 2, the oil damper 5 and the friction damper 16 act together at the same time as in the first embodiment, and the vibration of the structure can be damped and suppressed.

Finally, FIG. 9 shows a comparison of the vibration response of the conventional non-damping structure, viscous type structure, hysteresis type structure and the vibration damping structure of the present invention on the structure side to the external vibration force. As shown by the chain double-dashed line, the vibration support structure linearly produces a response vibration in proportion to the external vibration force. Here, in the case of a support structure that uses only viscous dampers, the vibration is reduced to nearly half compared to the above non-vibration structure with a constant viscous resistance, but a region where the vibration external force dangerous to the structure is high. In (dotted line part), the function of suppressing the vibration cannot be exerted on the structure. Further, the structure having only the hysteresis type damper shown in FIG. 10 does not have a damping action at the initial stage of vibration, and therefore a large shock is suddenly generated when the damping action occurs.

On the other hand, in the viscous and hysteretic type combined structure of the present invention, the damping force by the viscous damper works in the region where the external vibration force is low, and the hysteresis damper in the high external vibration force region where the hysteresis damper starts to operate. The strong damping force of is added and it continues to act, and the damping effect in the large vibration external force region is remarkably enhanced.

Therefore, in any of the above structures, the structure mutual action is achieved by the combined action of the continuous damping action of the viscous damper 5 and the damping action of the hysteresis damper 6 or 16 in the large vibration external force region. It is possible to efficiently reduce and suppress the vibration generated between the two. As a result, it is possible to reduce the vibration of the entire structure, improve the safety of the structure, and reduce the weight of the structure.
