Description

本発明は、固有周期の異なる複数の構造物を制振装置により連結してなる制振構造物に関する。   The present invention relates to a vibration damping structure formed by connecting a plurality of structures having different natural periods with a vibration damping device.

従来より、高層建物では、地震力や風荷重による大きな水平力が入力されると、それに応じて建物に大きな変位が生じてしまうため、柱や梁の本数を増やしたり、柱や梁の断面積を大きしたりするなどの方法により建物の剛性を高めて耐震性を向上している。しかしながら、かかる方法では、建物の開口面積が減ってしまったり、居住空間が削られてしまったりするなど、平面計画上の障害になるという問題があった。   Conventionally, in a high-rise building, if a large horizontal force due to seismic force or wind load is input, the building will undergo a large displacement accordingly, so the number of columns and beams will increase, or the cross-sectional area of the columns and beams will increase. By increasing the size of the building, the rigidity of the building is increased to improve earthquake resistance. However, such a method has a problem in that the plan area becomes an obstacle, for example, the opening area of the building is reduced or the living space is shaved.

そこで、本願出願人らは、建物本体を構成する外部建物内に、剛性が高く、固有周期が異なる内部構造体を設け、外部建物と内部構造体との間を制振ダンパーにより接続した制振構造物を提案している（例えば、特許文献１及び２参照）。このような制振構造物によれば、外部建物と内部構造体とが固有周期が異なることで、変形モードが異なり、制振ダンパーにより効率よく振動エネルギーを吸収することができるため、外部建物の剛性を高めなくても耐震性を持たせることができ、上記のような問題を解決することできる。
特開２００６―２４１７８３号公報 特開２００５―１８００８９号公報 Therefore, the applicants of the present application provided an internal structure with high rigidity and different natural period in the external building constituting the building main body, and connected the external building and the internal structure with a vibration damper. A structure has been proposed (see, for example, Patent Documents 1 and 2). According to such a vibration control structure, since the external building and the internal structure have different natural periods, the deformation modes are different, and vibration energy can be efficiently absorbed by the vibration damper. Even if the rigidity is not increased, it is possible to provide earthquake resistance and solve the above problems.
JP 2006-241783 A Japanese Patent Laid-Open No. 2005-180089

しかしながら、上記のような制振構造物において、内部構造体の幅や奥行きに対する高さの比が大きい場合には、地震動や制振ダンパーの反力に対する内部構造体の剛性が小さくなってしまい、外部建物との固有周期の差が小さくなるため、外部建物に対する制振効果が十分に得られなくなるという問題があった。   However, in the damping structure as described above, when the ratio of the height to the width and depth of the internal structure is large, the rigidity of the internal structure with respect to the reaction force of the earthquake motion and the damping damper becomes small, Since the difference in natural period with the external building is small, there is a problem that the vibration control effect on the external building cannot be obtained sufficiently.

本発明は、上記の問題に鑑みなされたものであって、その目的は、固有周期の異なる構造物を制振装置により連結してなる制振構造物において、剛性が高い構造物の水平方向の幅や奥行きに対する高さの比が大きい場合であっても、十分な制振効果が得られるようにすることである。   The present invention has been made in view of the above problems, and an object of the present invention is to provide a horizontal structure of a structure having high rigidity in a vibration control structure in which structures having different natural periods are connected by a vibration control device. Even when the ratio of height to width and depth is large, a sufficient vibration damping effect is obtained.

本発明の制振構造物は、上下方向に延びるボイド空間を内部に有する第１の構造体と、前記ボイド空間内に構築され、当該第１の構造体と異なる固有周期を有して当該第１の構造体よりも高い剛性を有する一以上の第２の構造体と、一又は複数の高さ位置において前記第１の構造体と第２の構造体とを連結する水平制振装置と、を備えた制振構造物であって、前記第１の構造体と前記第２の構造体とは少なくとも上部で分離しており、前記第１の構造体及び前記第２の構造体の上部における両者の鉛直方向の相対変位を抑制する鉛直変位抑制機構を有し、前記鉛直変位抑制機構は、前記第１又は第２の構造体のうちの高い方の構造物の上部から横方向に突出する取付部材と、前記取付部材と前記第１の構造体又は第２の構造体のうちの他方の上部とを結ぶように取り付けられた鉛直制振装置と、からなり、前記鉛直制振装置は、その両端が夫々、いかなる方向にも回転できるように接続されていることを特徴とする。 Damping structure of the present invention includes a first structure having a void space extending vertically therein, the built void space, the first to have a the different natural period first structure a second structure of one or more of have a higher rigidity than the first structure, and a horizontal damping device for connecting said a first structure and the second structure in one or more of height The first structure and the second structure are separated at least at the upper part, and the upper part of the first structure and the second structure. And a vertical displacement suppression mechanism that suppresses the relative displacement in the vertical direction of the two, wherein the vertical displacement suppression mechanism protrudes laterally from the upper part of the higher one of the first or second structures. An attachment member, and the other of the attachment member and the first structure or the second structure. And a vertical vibration control device which is mounted so as to connect the parts, made, the vertical damping devices, s and both ends of each, characterized in that it is connected so that it can rotate in any direction.

上記の制振構造物において、前記鉛直変位抑制機構は、前記他方の構造体の上部から横方向に突出する取付部材を備え、前記鉛直制振装置は、前記高い方の構造体の上部から横方向に突出する取付部材と、前記他方の構造体の上部から横方向に突出する取付部材とを結ぶように取付けられていてもよい。 In the damping structure, the vertical displacement suppression mechanism includes a mounting member which projects laterally from the upper portion of the other structure, the vertical damping device is horizontal from the top of the higher structure a mounting member which projects in the direction, may be attached so as to connect the mounting member which projects laterally from the upper portion of the other structure.

また、前記高い方の構造体は、前記第１の構造体であり、前記取付部材は、前記高い方の構造体の上部において、前記他方の構造体の上方を跨ぐように掛け渡されていてもよい。 Also, the higher structure, the a first structure, wherein the mounting member is at the top of the higher structure, have been stretched so as to straddle the upper of the other structure Also good.

本発明によれば、固有周期の異なる複数の構造物の鉛直方向変位を抑制することにより、何れかの構造物が水平方向の幅や奥行きに対する高さの比が大きい場合であっても、この構造物に曲げ変形が発生するのを抑えることができ、実質的に剛性を向上することができるため、十分な制振効果が得られる。   According to the present invention, by suppressing the vertical displacement of a plurality of structures having different natural periods, even if any structure has a large ratio of the height to the width or depth in the horizontal direction, Since the occurrence of bending deformation in the structure can be suppressed and the rigidity can be substantially improved, a sufficient vibration damping effect can be obtained.

以下、本発明の制振構造物の一実施形態を図面を参照しながら詳細に説明する。
図１は、本実施形態の制振構造物１０の構成を示し、（Ａ）は鉛直方向断面図、（Ｂ）は水平方向断面図である。同図に示すように、本実施形態の制振構造物１０は、内部に上下方向に延びるボイド空間２１を有する外部建物２０と、ボイド空間２１内に構築された内部構造物３０と、外部建物２０と内部構造物３０とを接続するように、ボイド空間２１内の複数の高さ位置に設けられた水平制振装置４０と、外部建物２０及び内部構造物３０の最上部を結ぶように設けられ、これら外部建物２０と内部構造物３０との鉛直方向の相対変位を抑制する鉛直変位抑制機構５０と、を備える。 Hereinafter, an embodiment of a vibration damping structure of the present invention will be described in detail with reference to the drawings.
1A and 1B show a configuration of a vibration damping structure 10 of the present embodiment, in which FIG. 1A is a vertical sectional view and FIG. 1B is a horizontal sectional view. As shown in the figure, the vibration damping structure 10 of the present embodiment includes an external building 20 having a void space 21 extending in the vertical direction inside, an internal structure 30 constructed in the void space 21, and an external building. 20 and the internal structure 30 are provided so as to connect the horizontal vibration control device 40 provided at a plurality of height positions in the void space 21 to the uppermost part of the external building 20 and the internal structure 30. And a vertical displacement suppression mechanism 50 that suppresses the relative displacement in the vertical direction between the external building 20 and the internal structure 30.

外部建物２０は平面視矩形に形成され、上述のように内部に上下方向に延びるボイド空間２１を有する高層建物である。外部建物２０としては、例えば、鉄骨造、鉄筋コンクリート造、鉄骨鉄筋コンクリート造などを採用することができる。   The external building 20 is a high-rise building which is formed in a rectangular shape in plan view and has a void space 21 extending in the vertical direction inside as described above. As the external building 20, for example, a steel structure, a reinforced concrete structure, a steel reinforced concrete structure, or the like can be adopted.

内部構造物３０は、外部建物２０と同様に、例えば、鉄骨造、鉄筋コンクリート造、鉄骨鉄筋コンクリート造などを採用することができる。内部構造物３０は、構造耐力を負担する構造要素として利用してもよいし、建物として利用してもよい。また、内部構造物３０は、外部建物２０に比べて高い剛性を有するように構築されている。さらに、内部構造物３０は、その幅及び奥行きに比べて高さの比が大きい。   The internal structure 30 can employ, for example, a steel structure, a reinforced concrete structure, a steel reinforced concrete structure, or the like, as with the external building 20. The internal structure 30 may be used as a structural element that bears structural strength, or may be used as a building. Further, the internal structure 30 is constructed so as to have higher rigidity than the external building 20. Furthermore, the height ratio of the internal structure 30 is larger than its width and depth.

水平制振装置４０は、外部建物２０内のボイド空間２１のコーナー部と、内部構造物３０のコーナー部とを結ぶように略水平に設けられている。なお、水平制振装置４０としては油圧ダンパーや鋼材ダンパー等、内部構造物３０と外部建物２０の相対変位に合わせて変形するとともに、エネルギーを吸収する制振装置であれば用いることができる。また、水平制振装置４０の接続の仕方は、必ずしも、図１（Ｂ）に示すように配置する必要はなく、外部建物２０と内部構造物３０の何れの方向の相対変位に対しても、何れかの水平制振装置４０が変形してエネルギーを吸収できる配置であればよい。   The horizontal vibration damping device 40 is provided substantially horizontally so as to connect the corner portion of the void space 21 in the external building 20 and the corner portion of the internal structure 30. The horizontal vibration damping device 40 may be any vibration damping device that absorbs energy while being deformed according to the relative displacement between the internal structure 30 and the external building 20, such as a hydraulic damper or a steel damper. Moreover, the connection method of the horizontal vibration damping device 40 is not necessarily arranged as shown in FIG. 1 (B), and the relative displacement in any direction of the external building 20 and the internal structure 30 Any horizontal damping device 40 may be disposed so long as it can absorb energy by deformation.

ここで、本実施形態の内部構造物３０のように、幅及び奥行きに比べて高さの比が大きいような建物は剛性が低く、水平力が作用すると大きな曲げ変形が生じやすい。図２は、単独の内部構造物３０に水平力が作用した様子を示す図である。同図に示すように、内部構造物３０に図中矢印の方向の水平力が作用すると、内部構造物３０には曲げ変形が生じ、上端部の図中左側が上方へと移動するとともに、上端部の図中右側が下方へ移動する。このような上下変位を抑制するべく、本実施形態では、外部建物２０及び内部構造物３０の最上部を結ぶように鉛直変位抑制機構５０を設けている。   Here, like the internal structure 30 of the present embodiment, a building having a large height ratio compared to the width and depth has low rigidity, and a large bending deformation is likely to occur when a horizontal force is applied. FIG. 2 is a diagram illustrating a state in which a horizontal force is applied to a single internal structure 30. As shown in the figure, when a horizontal force in the direction of the arrow in the figure acts on the internal structure 30, bending deformation occurs in the internal structure 30, the left side of the upper end in the figure moves upward, The right side in the figure moves downward. In the present embodiment, the vertical displacement suppression mechanism 50 is provided so as to connect the uppermost portions of the external building 20 and the internal structure 30 in order to suppress such vertical displacement.

図３は、外部建物２０と内部構造物３０の上部を結ぶように設けられた鉛直変位抑制機構５０を示す拡大図である。同図に示すように、鉛直変位抑制機構５０は、外部建物２０の最上部に、水平方向に突出し、その先端が内部構造物３０の上方まで到達するように設けられた取付部材５１と、取付部材５１の先端と内部構造物３０とを結ぶように鉛直方向に立設された鉛直制振装置５２とにより構成される。
取付部材５１は、外部構造物２０の梁と同様の構成であり、特に鉛直方向に大きな剛性を有する。
鉛直制振装置５２としては、油圧ダンパーや鋼材ダンパーなどの鉛直方向の変形エネルギーを吸収可能な制振装置を用いることができる。 FIG. 3 is an enlarged view showing the vertical displacement suppression mechanism 50 provided so as to connect the outer building 20 and the upper part of the internal structure 30. As shown in the figure, the vertical displacement suppression mechanism 50 includes an attachment member 51 provided so as to protrude in the horizontal direction at the uppermost portion of the external building 20 and the tip thereof reaches the upper portion of the internal structure 30. A vertical vibration control device 52 is provided in a vertical direction so as to connect the tip of the member 51 and the internal structure 30.
The attachment member 51 has the same configuration as that of the beam of the external structure 20, and has a large rigidity particularly in the vertical direction.
As the vertical damping device 52, a damping device capable of absorbing vertical deformation energy, such as a hydraulic damper or a steel damper, can be used.

鉛直制振装置５２の上端は、自在継手５４により水平視における何れの方向にも回動できるように取付部材５１に接続されている。また、鉛直制振装置５２の下端も、自在継手５３により水平視における何れの方向にも回動できるように内部構造物３０の最上部に接続されている。かかる構成により、外部建物２０と、内部構造物３０とが水平方向のいかなる方向に相対変位したとしても、鉛直制振装置５２がこの相対変位した方向に向くように回動し、鉛直方向に対して傾斜して、この相対変位に追従することができるので、鉛直制振装置５２の破損を防止して、鉛直方向の制振性能を維持することができる。   The upper end of the vertical vibration damping device 52 is connected to the mounting member 51 so that it can be rotated in any direction in the horizontal view by a universal joint 54. The lower end of the vertical vibration damping device 52 is also connected to the uppermost part of the internal structure 30 so that it can be rotated in any direction in the horizontal view by the universal joint 53. With this configuration, even if the external building 20 and the internal structure 30 are relatively displaced in any horizontal direction, the vertical vibration damping device 52 is rotated so as to be directed in the relative displaced direction, and the vertical direction is thus changed. Therefore, the vertical vibration damping device 52 can be prevented from being damaged and the vibration damping performance in the vertical direction can be maintained.

かかる構成の制振構造物１０に地震力が作用すると、内部構造物３０は、図２に示すような曲げ変形をしようとする。この際、上記のように、内部構造物３０の上端部の水平力の作用する側は上方へ、上端部の水平力が作用する側と反対側は下方へ移動しようとする。   When seismic force acts on the vibration damping structure 10 having such a configuration, the internal structure 30 tends to bend and deform as shown in FIG. At this time, as described above, the side where the horizontal force acts on the upper end of the internal structure 30 tends to move upward, and the side opposite to the side where the horizontal force acts on the upper end tends to move downward.

これに対して、内部構造物３０と外部建物２０との間を結ぶように設けられた鉛直制振装置５２がこの鉛直方向の相対変位に対して抵抗する。これにより、内部構造物３０に生じる曲げ変形が小さくなることで、内部構造物３０は水平力に対して剛性の高い構造物と同様の挙動を示すこととなる。   On the other hand, the vertical damping device 52 provided to connect the internal structure 30 and the external building 20 resists the relative displacement in the vertical direction. Thereby, the bending deformation which arises in the internal structure 30 becomes small, and the internal structure 30 will show the same behavior as a structure with high rigidity with respect to a horizontal force.

このため、高さに対して幅や奥行きが小さな内部構造物３０であっても、外部建物２０と内部構造物３０の固有周期の差が小さくなることがなく、外部建物２０と内部構造物３０とが異なる振動モードで振動し、水平制振装置４０により十分に振動エネルギーを吸収することができる。   For this reason, even if it is the internal structure 30 with a small width | variety and depth with respect to height, the difference of the natural period of the external building 20 and the internal structure 30 does not become small, and the external building 20 and the internal structure 30 Vibrate in different vibration modes, and the horizontal damping device 40 can sufficiently absorb vibration energy.

以上説明したように、本実施形態によれば、内部構造物３０と外部建物２０の最上階との間に鉛直制振装置５２を設けることにより、これら内部構造物３０と外部建物２０との間で生じる鉛直方向の相対変位を抑えることができる。このため、内部構造物３０が剛性の高い構造物と同様の挙動を示し、内部構造物３０が幅や奥行きが小さい場合であっても、十分な制振効果が得られる。   As described above, according to the present embodiment, by providing the vertical vibration damping device 52 between the internal structure 30 and the top floor of the external building 20, the space between the internal structure 30 and the external building 20 is provided. The relative displacement in the vertical direction that occurs in For this reason, even if the internal structure 30 exhibits the same behavior as a highly rigid structure and the internal structure 30 is small in width and depth, a sufficient vibration damping effect can be obtained.

また、鉛直制振装置５２が変形することにより振動エネルギーを吸収するため、さらに、効率良く外部建物２０を制振することができる。   Further, since the vibration damping energy is absorbed by the deformation of the vertical vibration damping device 52, the external building 20 can be further efficiently damped.

なお、本実施形態では、鉛直制振装置５２の両端を、夫々、水平視何れの方向にも回動可能に接続することにより、外部建物２０と内部構造物３０とが水平視何れの方向に相対変位したとしても、これに追従できるようにしたが、これに限らず、以下に説明するように接続することにより相対変位に追従することとしてもよい。   In the present embodiment, both ends of the vertical damping device 52 are connected so as to be rotatable in any direction in the horizontal view, so that the external building 20 and the internal structure 30 are in any direction in the horizontal view. Even if the relative displacement occurs, it is possible to follow this. However, the present invention is not limited to this, and it is also possible to follow the relative displacement by connecting as described below.

図４は鉛直制振装置５２別の接続方法を示す図である。同図（Ａ）に示す例では、鉛直制振装置５２の一端（図４の例では上端）を図中のＸＺ平面で回動可能に接続し、他方の端部（図４の例では下端）をＸＺ平面で回動可能、かつ、Ｙ方向にスライド可能に接続している。   FIG. 4 is a diagram illustrating a connection method according to the vertical vibration control device 52. In the example shown in FIG. 4A, one end (upper end in the example of FIG. 4) of the vertical vibration damping device 52 is rotatably connected on the XZ plane in the drawing, and the other end (lower end in the example of FIG. 4). ) Can be rotated in the XZ plane and slidable in the Y direction.

このように接続した場合であっても、例えば、外部建物２０と内部構造物３０とＸ方向の相対変位が生じた場合には、同図（Ｂ）に示すように、鉛直制振装置５２がＸＺ平面内で回動して傾斜することにより、この相対変位に追従することができる。また、同図（Ｃ）に示すように、Ｙ方向の相対変位が生じた場合には、鉛直制振装置５２の下端がＹ方向にスライドすることにより、これに追従することができる。このように鉛直制振装置５２がＸ方向、Ｙ方向の変位に追従可能であるため、外部建物２０と内部構造物３０との間に水平方向に何れの方向に変位が生じた場合であっても、これに追従することができる。   Even in such a case, for example, when relative displacement in the X direction occurs between the external building 20 and the internal structure 30, as shown in FIG. By rotating and tilting in the XZ plane, it is possible to follow this relative displacement. Further, as shown in FIG. 5C, when relative displacement in the Y direction occurs, the lower end of the vertical vibration damping device 52 slides in the Y direction, so that this can be followed. Since the vertical damping device 52 can follow the displacement in the X direction and the Y direction in this way, the displacement is generated in any direction in the horizontal direction between the external building 20 and the internal structure 30. Can also follow this.

また、図４を参照して説明した鉛直制振装置５２の接続例では鉛直制振装置５２の両端を水平面に対して垂直なＸＺ平面内を回動可能とすることにより、Ｘ方向の相対変位に追従し、下端をＸＺ平面に対して垂直なＹ方向にスライド可能に接続することによりＹ方向の相対変位に追従することとしたが、必ずしも、鉛直制振装置５２の両端は水平面に対して垂直な面内を回動可能とする必要はなく、両端が水平面から外れた回動面内を回動可能に接続されていればよく、また、回動面に対して垂直方向にスライド可能にする必要はなく、回動面から外れた方向（すなわち、回動面に交わる方向）にスライド可能であればよい。   Further, in the connection example of the vertical vibration damping device 52 described with reference to FIG. 4, the relative displacement in the X direction can be achieved by making both ends of the vertical vibration damping device 52 rotatable in the XZ plane perpendicular to the horizontal plane. The lower end of the vertical vibration control device 52 is slidably connected in the Y direction perpendicular to the XZ plane so as to follow the relative displacement in the Y direction. It is not necessary to be able to rotate in a vertical plane, it is only necessary that both ends are connected so as to be able to rotate in a rotating plane that is out of the horizontal plane, and it can slide in a direction perpendicular to the rotating plane. There is no need to do so, as long as it is slidable in a direction away from the rotation surface (that is, a direction intersecting the rotation surface).

さらに、鉛直制振装置５２の何れか一方の端部を固定し、他方の端部を水平面上いずれの方向にもすべり可能に構成することとしてもよい。また、鉛直制振装置５２の一端を水平方向に一方向にすべり可能とし、他端を前記一方向と異なる方向にすべり可能としてもよい。要するに、外部建物２０と内部構造物３０とが水平方向に相対変位しても、これに追従できる構成であればよい。   Further, any one end of the vertical vibration damping device 52 may be fixed, and the other end may be configured to be able to slide in any direction on the horizontal plane. Further, one end of the vertical vibration damping device 52 may be slidable in one direction in the horizontal direction, and the other end may be slidable in a direction different from the one direction. In short, what is necessary is just a structure which can follow this, even if the external building 20 and the internal structure 30 are relatively displaced in the horizontal direction.

また、本実施形態では、外部建物２０から取付部材５１を突出させ、鉛直制振装置５２の上端をこの取付部材５１に接続し、下端を内部構造物３０の上部に接続するものとしたが、これに限らず、図５（Ａ）に示すように、外部建物２０及び内部構造物３０、夫々に水平方向に突出する取付部材１５３、１５１を設け、これら取付部材１５３、１５１に鉛直制振装置１５２の両端を接続してもよい。また、図５（Ｂ）に示すように、外部建物２０にボイド空間２１の上部を跨ぐように取付部材２５１を掛け渡し、この取付部材２５１と内部構造物３０の上部とを結ぶように鉛直制振装置２５２を設けてもよい。   In the present embodiment, the mounting member 51 is protruded from the external building 20, the upper end of the vertical vibration damping device 52 is connected to the mounting member 51, and the lower end is connected to the upper part of the internal structure 30. Not limited to this, as shown in FIG. 5 (A), the external building 20 and the internal structure 30 are provided with mounting members 153 and 151 that protrude in the horizontal direction, and the vertical damping device is provided on these mounting members 153 and 151. Both ends of 152 may be connected. Further, as shown in FIG. 5 (B), a mounting member 251 is stretched over the external building 20 so as to straddle the upper part of the void space 21, and the vertical control is performed so as to connect the mounting member 251 and the upper part of the internal structure 30. A vibration device 252 may be provided.

また、本実施形態では、外部建物２０と、内部構造物３０とを結ぶように、鉛直制振装置５２の両端を接続するものとしたが、これに限らず、鉛直方向の剛性が高い剛材を接続するものとしてもよい。かかる場合であっても、内部構造物３０が曲げ変形を生じようとすると、この曲げ変形が剛材により抑えられるため、内部構造物３０の剛性を向上することができる。なお、この際、上端又は下端を水平視何れの方向にもすべり可能とするなど、剛材が伸縮しなくても、外部建物２０と内部構造物３０との間の水平変位に追従できる機構が必要となる。   In the present embodiment, both ends of the vertical vibration damping device 52 are connected so as to connect the external building 20 and the internal structure 30. However, the present invention is not limited to this, and a rigid material having high vertical rigidity. May be connected. Even in such a case, if the internal structure 30 is to bend and deform, the bending deformation is suppressed by the rigid material, so that the rigidity of the internal structure 30 can be improved. At this time, there is a mechanism that can follow the horizontal displacement between the external building 20 and the internal structure 30 even if the rigid material does not expand and contract, such as allowing the upper end or the lower end to slide in any direction in the horizontal view. Necessary.

また、本実施形態では、鉛直制振装置５２を鉛直方向に延びるように設置することとしたが、これに限らず、傾斜させて設置してもよく、要するに、外部建物２０と内部構造物３０との間の鉛直変位を抑制できればよい。なお、このように鉛直制振装置５２を傾斜させて設置する場合には、鉛直制振装置５２に水平制振装置としての機能も持たせることが可能となる。   In the present embodiment, the vertical vibration damping device 52 is installed so as to extend in the vertical direction. However, the present invention is not limited to this, and may be installed in an inclined manner. In short, the external building 20 and the internal structure 30 are provided. What is necessary is just to be able to suppress the vertical displacement between. When the vertical vibration damping device 52 is installed in an inclined manner as described above, the vertical vibration damping device 52 can also have a function as a horizontal vibration damping device.
