The rigidity of the building frame is changed according to the earthquake, etc., in order to cope with earthquakes, etc.

Conventionally, in the seismic design of high-rise buildings and important structures, dynamic design has been performed to check safety by calculating the ground movement and building response during an earthquake.

対する信頼性の問題がある。 By the way, confirmation of the safety of buildings designed using current seismic design methods in the event of an earthquake is based on the basic idea that the energy absorbed by the hysteresis characteristics associated with plasticization of the structure exceeds the seismic energy acting on the structure. However, this has the problem of reliability regarding the history loop characteristics.

ことはできない。 In addition, all conventional methods provide a passive seismic structure against natural external forces such as earthquakes and wind, and because buildings have a specific natural frequency, they do not allow resonance phenomena to occur against uncertain inputs such as earthquakes. You can't avoid it.

図つた制震方法を提案している。 In contrast, in Japanese Patent Application No. 61-112026 (Japanese Unexamined Patent Publication No. 62-268479), the applicant proposed a method based on the judgment of a response prediction system based on detected earthquakes, etc., rather than the passive seismic method described above. We are proposing a vibration damping method that changes the rigidity of the building itself to bring it out of the resonance region or into a state with less resonance, thereby ensuring the safety of the building, its equipment, residents, etc.

Wide-area earthquake sensing equipment connects seismometers at existing earthquake observation points or specially installed equipment using micro-wires or telephone lines. In addition, narrow-area earthquake sensing devices consist of seismometers installed around buildings or in the surrounding ground, and vibration sensors installed at the base of buildings or inside buildings, and the effects of wind force etc. are detected by vibration sensors inside buildings.

The connection state can be adjusted by turning the fixed state and uncoupled state on and off using hydraulic mechanisms, electromagnets, etc., and in addition to the fixed state and disconnected state,
It is conceivable to use a hydraulic mechanism or a special alloy to adjust the introduction of tension force and fixation at an arbitrary position.

次に、第５図ａ，ｂに基づいて、剛性変化のメ
カニズムを説明する。 Next, the mechanism of rigidity change will be explained based on FIGS. 5a and 5b.
ばね１３，１４はピストン１０，１１のストロ
ークの範囲内では線型の変形特性を示し、装置５
にはばね１３，１４の基本剛性による比較的低い
剛性状態が得られる。 The springs 13, 14 exhibit linear deformation characteristics within the stroke of the pistons 10, 11, and the device 5
A relatively low stiffness state is obtained due to the basic stiffness of the springs 13 and 14.
粉粒体１６は前述のように油圧等で圧縮するこ

シリンダー７を固定した部材の相対移動による圧
縮力解除の際も、高い引張剛性が得られる。以
下、プレストレスを与えた状態を基準の圧力と考
え、このときを無加圧状態とする。 As described above, the granular material 16 exhibits high rigidity when compressed by hydraulic pressure or the like, but does not exhibit resistance to tension when the pressure is 0 (see FIG. 7).
Therefore, if a predetermined pressure is applied in advance in the form of prestress, the first cylinder 6 and the second cylinder
Even when the compressive force is released by relative movement of the members fixing the cylinder 7, high tensile rigidity can be obtained. Hereinafter, the state in which prestress is applied will be considered as the reference pressure, and this time will be referred to as the non-pressurized state.
また、高吸水性樹脂等の粒状の液体吸収物質
（液体を吸収して、ゲル状態になる）を混入すれ
ば、無加圧あるいは低加圧時には、液体がない場
合に比べて、低い剛性となるので、剛性の変化幅
を広げることができる。 In addition, if a granular liquid-absorbing material (absorbs liquid and becomes a gel) such as a super absorbent resin is mixed in, the rigidity will be lower when no pressure is applied or when pressurized at low pressure than when there is no liquid. Therefore, the range of changes in rigidity can be expanded.
次に、第６図ａ，ｂに基づいて、力の伝達のメ
カニズムを説明する。 Next, the mechanism of force transmission will be explained based on FIGS. 6a and 6b.
第２シリンダー７を固定した梁２から、第１
シリンダー６を固定したブレース３への力の伝
達は次のようになる。 From the beam 2 to which the second cylinder 7 is fixed, the first
The transmission of force to the brace 3 that fixed the cylinder 6 is as follows.
図中、左側の第２シリンダー７が引張力P1
を受けるときは、右側の第２シリンダー７が圧
縮力P1を受ける。 In the figure, the second cylinder 7 on the left has a tensile force P 1
When receiving the compressive force P1, the second cylinder 7 on the right side receives the compressive force P1 .
梁２からの引張力P1は、左側の第２シリン

ピストン１０に対する第１シリンダー６のばね
１３の剛性と粉粒体１６の圧縮による圧縮剛性
で、ブレース３に水平力P2を伝達する。 The tensile force P 1 from the beam 2 is transmitted to the piston 11 by the stiffness of the spring 14 of the second cylinder 7 on the left side and the tensile stiffness due to the decompression of the powder 16,
The horizontal force P 2 is transmitted to the brace 3 by the stiffness of the spring 13 of the first cylinder 6 with respect to the piston 10 and the compression stiffness due to the compression of the powder 16.
梁２からの圧縮力P1は、右側の第２シリン

で、ブレース３に水平力P2′を伝達する。 The compressive force P 1 from the beam 2 is transmitted to the piston 11 by the stiffness of the spring 14 of the second cylinder 7 on the right side and the compression stiffness due to the compression of the powder 16, and the spring 13 of the first cylinder 6 relative to the piston 10 is transmitted to the piston 11.
The horizontal force P 2 ' is transmitted to the brace 3 by the rigidity of P 2 ' and the tensile rigidity due to the decompression of the powder 16.
結局、左右の第２シリンダー７から同じ伝達
機構（圧縮と引張）を通るので、両者同じ剛性
になる。 After all, since the left and right second cylinders 7 pass through the same transmission mechanism (compression and tension), both have the same rigidity.
加圧時に第１シリンダー６（および第２シリ

の関係を示したものである。 When a force exceeding the pressure applied to the first cylinder 6 (and second cylinder 7) is applied from the left and right second cylinders 7 during pressurization, the tensile rigidity returns to the basic rigidity and the rigidity decreases. Figure 3 is 0
At this point, in other words, when no horizontal force is acting on the device 5, by changing the pressurizing force, the stiffness is varied in various ways, and the separation load (indicated by a circle in the figure) and the stiffness change in the load deformation curve at this time. This shows the relationship between

にする。 If a pressure reduction operation, that is, an operation to reduce the stiffness, is performed while a load is applied, an unstable state may occur due to the release of force (see Fig. 4), but as shown in Fig. 1, the piston 10, 1
1 is provided with a damper valve 19 that opens only when the pressure changes from high to low.
5 passes, the damper function works, and this shock can be softened. Note that a filter or the like is provided at the damper valve 19 position and the liquid reservoir 20 position to prevent the powder 16 from passing through.
離間荷重までの高い剛性は加圧力の大きさに
よつて決まる（第３図参照）が、これによつて
伝達できる力は左右同時に伝わるので、加圧力
の倍の力になり、装置としての効率がよい。 High rigidity up to a distance load is determined by the magnitude of the pressurizing force (see Figure 3), but since the force that can be transmitted by this is transmitted simultaneously to the left and right sides, it is twice the pressurizing force, increasing the efficiency of the device. Good.

This is an example of a simple type variable rigidity joining device 5 that does not use a double cylinder type in which air holes 21 are formed on the spring 13 and 14 sides of the first cylinder 6 and the second cylinder 7.

力が加わつた時点から高い剛性状態に移る。 When no pressure is applied, the springs 13 and 14 are in a low rigidity state as shown in FIG. This results in a high rigidity state. FIG. 9 shows this relationship. That is, the low rigidity state caused by the springs 13 and 14 changes to a high rigidity state from the time when a pressing force sufficient to bring the springs 13 and 14 into close contact is applied.
