Description

本発明は、制振構造物及び制振方法に関し、特に、高層のオフィス建物に有効な制振構造物及び制振方法に関する。   The present invention relates to a vibration damping structure and a vibration damping method, and more particularly to a vibration damping structure and a vibration damping method effective for a high-rise office building.

駐車設備付きの建造物の一例が特許文献１に記載されている。この建造物は、中央部に平面視矩形状のボイド空間が設けられ、ボイド空間の周囲にボイド空間を囲むように平面視ロ形状の居住空間が設けられた高層マンション等の建造物であって、ボイド空間を利用して立体駐車設備を設けるとともに、ボイド空間と居住空間との間に耐火壁を設けて、立体駐車設備側又は居住空間側からの出火が居住空間側又は立体駐車設備側に延焼するのを防止するように構成したものである。   An example of a building with parking facilities is described in Patent Document 1. This building is a building such as a high-rise condominium in which a void space having a rectangular shape in plan view is provided in the center, and a living space having a rectangular shape in plan view is provided around the void space. In addition to providing a three-dimensional parking facility using the void space, providing a fireproof wall between the void space and the living space, the fire from the three-dimensional parking facility side or the living space side is on the living space side or the three-dimensional parking facility side It is configured to prevent the spread of fire.

特許第２６２３４７９号公報Japanese Patent No. 2623479

ところで、上記のような構成の建造物にあっては、中心部のボイド空間内に立体駐車設備が設けられ、ボイド空間の外側に居住空間が設けられているため、所望の耐震性を付加するためには、使用する柱及び梁の本数が多くし、柱間のスパンを狭くして、建造物の剛性を高めなければならない。このため、各階を、有効床面積が広く、柱間のスパンが広い、開放的なオフィス空間として利用することができず、設計の自由度が低下してしまう。   By the way, in the structure of the above structure, since the multilevel parking equipment is provided in the void space in the center and the living space is provided outside the void space, desired earthquake resistance is added. For this purpose, the number of columns and beams to be used must be increased, and the span between the columns must be narrowed to increase the rigidity of the building. For this reason, each floor cannot be used as an open office space with a large effective floor area and a wide span between pillars, and the degree of freedom in design is reduced.

本発明は、上記のような従来の問題に鑑みなされたものであって、高層のオフィス建物として利用した場合、設計の自由度が高く、各階を、有効床面積が広く、柱間のスパンが広い、開放的なオフィス空間として有効利用することができる、所望の耐震性を備えた制振構造物及び制振方法を提供することを目的とする。   The present invention has been made in view of the above-described conventional problems, and when used as a high-rise office building, the design freedom is high, each floor has a large effective floor area, and the span between columns is large. An object of the present invention is to provide a vibration damping structure and a vibration damping method having desired earthquake resistance that can be effectively used as a wide and open office space.

上記のような課題を解決するために、本発明は、以下のような手段を採用している。
すなわち、本発明は、第１構造物と、該第１構造物と間隔をおいて、かつ該第１構造物を囲むように設けられるとともに、該第１構造物よりも高い剛性を有する第２構造物と、前記第１構造物と前記第２構造物との間に介装されて、両者間を相対変位可能に連結する複数の制振装置とを備えていることを特徴とする。 In order to solve the above problems, the present invention employs the following means.
That is, the present invention provides a first structure, a second structure that is spaced from the first structure and surrounds the first structure, and has higher rigidity than the first structure. It is characterized by comprising a structure and a plurality of vibration control devices interposed between the first structure and the second structure so as to be connected to each other so as to be relatively displaceable.

本発明の制振構造物によれば、地震等の外力の入力時に、第１構造物と第２構造物とは、異なる振動モードで振動し、両者の振動エネルギーが制振装置で吸収されることにより、第１構造物の振動が低減されることになる。   According to the vibration damping structure of the present invention, when an external force such as an earthquake is input, the first structure and the second structure vibrate in different vibration modes, and both vibration energy is absorbed by the vibration damping device. As a result, the vibration of the first structure is reduced.

また、本発明は、前記第１構造物は、鉄骨構造の高層のオフィス建物であり、前記第２構造物は、鉄骨構造、コンクリート充填鋼管構造、又は鉄筋コンクリート構造の構造物であることとしてもよい。   In the present invention, the first structure may be a high-rise office building having a steel structure, and the second structure may be a steel structure, a concrete-filled steel pipe structure, or a reinforced concrete structure. .

本発明の制振構造物によれば、第１構造物である高層のオフィス建物は、剛性が低く設定されているので、使用する柱及び梁の本数が少なく、柱間のスパンを広くすることができ、各階のオフィス空間を、有効面積が広く、柱間のスパンが広い、開放的なオフィス空間として利用することができる。   According to the vibration damping structure of the present invention, since the high-rise office building as the first structure is set to have low rigidity, the number of columns and beams to be used is small, and the span between the columns is widened. The office space on each floor can be used as an open office space with a wide effective area and a wide span between pillars.

さらに、本発明は、前記第２構造物は、前記オフィス建物の各階に対応して配置される複数の庇を有していることとしてもよい。   Furthermore, the present invention may be configured such that the second structure has a plurality of eaves arranged corresponding to each floor of the office building.

本発明の制振構造物によれば、第２構造物の各庇により、オフィス建物への日射を遮ることができるので、オフィス建物の空調設備等の負荷を低減させることができ、省エネルギー化を図ることができる。   According to the vibration damping structure of the present invention, since the solar radiation to the office building can be blocked by the eaves of the second structure, it is possible to reduce the load on the air conditioning equipment of the office building and to save energy. Can be planned.

さらに、本発明は、前記第２構造物には、複数のソーラーパネルが取り付けられていることとしてもよい。   Furthermore, this invention is good also as a several solar panel being attached to the said 2nd structure.

本発明の制振構造物によれば、第１構造物の屋上や屋根等に設置スペースを設けることなく、第２構造物を利用してソーラーパネルを容易に取り付けることができる。   According to the vibration damping structure of the present invention, the solar panel can be easily attached using the second structure without providing an installation space on the roof or roof of the first structure.

さらに、本発明は、第１構造物の外側に、該第１構造物よりも剛性の高い第２構造物を間隔をおいて、かつ該第１構造物を囲むように設け、前記第１構造物と前記第２構造物との間に複数の制振装置を介装させて、該制振装置を介して前記第１構造物と前記第２構造物との間を相対変位可能に連結し、地震等の外力の入力時に、前記第１構造物と前記第２構造物とを異なる振動モードで振動させて、両者の振動を前記制振装置を介して減衰することにより、前記第１構造物の振動を低減させることを特徴とする。   Further, according to the present invention, a second structure having higher rigidity than the first structure is provided outside the first structure so as to be spaced from and surround the first structure. A plurality of vibration control devices are interposed between an object and the second structure, and the first structure and the second structure are connected via the vibration control device so as to be capable of relative displacement. When the external force such as an earthquake is input, the first structure and the second structure are vibrated in different vibration modes, and both vibrations are attenuated via the vibration control device, thereby the first structure. It is characterized by reducing vibrations of objects.

以上、説明したように、本発明によれば、地震等の外力の入力時に、第１構造物と第２構造物とは、異なる振動モードで振動し、両者の振動エネルギーが制振装置で吸収されることにより、第１構造物の振動が低減されることになる。この場合、第１建物は、剛性が低く設定されているので、第１建物を高層のオフィス建物とした場合、オフィス建物に使用する柱及び梁の本数を少なく、柱間のスパンを広くとることができる。従って、各階のオフィス空間を、有効床面積が広く、柱間のスパンが広い、開放的なオフィス空間とすることができる。   As described above, according to the present invention, when an external force such as an earthquake is input, the first structure and the second structure vibrate in different vibration modes, and both vibration energy is absorbed by the vibration damping device. As a result, the vibration of the first structure is reduced. In this case, since the first building is set to have low rigidity, when the first building is a high-rise office building, the number of columns and beams used for the office building should be small, and the span between the columns should be wide. Can do. Therefore, the office space on each floor can be an open office space with a large effective floor area and a wide span between pillars.

図１及び図２には、本発明による制振構造物及び制振方法の第１の実施の形態が示されていて、図１は、制振構造物の全体を示す概略図、図２は図１のＡ−Ａ線断面図である。   1 and 2 show a first embodiment of a vibration damping structure and a vibration damping method according to the present invention. FIG. 1 is a schematic view showing the whole of the vibration damping structure, and FIG. It is the sectional view on the AA line of FIG.

すなわち、本実施の形態の制振構造物１は、第１構造物２と、第１構造物２の外側に所定の間隔をおいて、かつ第１構造物２を囲むように設けられる第２構造物１０と、第１構造物２と第２構造物１０との間に介装されて、両者２、１０間を相対変位可能に連結する複数の制振装置１６とを備えている。   That is, the vibration damping structure 1 of the present embodiment is provided with a first structure 2 and a second space provided outside the first structure 2 with a predetermined interval and surrounding the first structure 2. A structure 10 and a plurality of vibration control devices 16 that are interposed between the first structure 2 and the second structure 10 and connect the two structures 2 and 10 so as to be relatively displaceable are provided.

第１構造物２は、例えば、平面視矩形状の鉄骨構造（Ｓ構造）の高層のオフィス建物であって、中心部に平面視矩形状のボイド空間５が上下方向に貫通した状態で設けられ、ボイド空間５の周囲に複数階層のオフィス空間６が設けられている。   The first structure 2 is, for example, a high-rise office building having a rectangular steel structure (S structure) in plan view, and is provided with a void space 5 having a rectangular shape in plan view penetrating in the vertical direction at the center. A multi-level office space 6 is provided around the void space 5.

第１構造物２は、一般的なラーメン架構の鉄骨構造の高層のオフィス建物に比べて、使用する柱３及び梁４の本数を少なく、かつ、柱３、３間のスパンを広くすることにより、全体の剛性を低く設定している。これにより、一般的なラーメン架構の鉄骨構造の高層のオフィス建物に比べて、各階のオフィス空間６の設計の自由度を高めることができ、各階のオフィス空間６の有効床面積を広く、柱３や梁４の本数の少ない開放的な空間とすることができる。   The first structure 2 has a smaller number of columns 3 and beams 4 to be used and a wider span between the columns 3 and 3 than a high-rise office building with a steel frame structure of a general frame structure. The overall rigidity is set low. As a result, the degree of freedom in designing the office space 6 on each floor can be increased compared with a high-rise office building with a steel frame structure with a general ramen frame, and the effective floor area of the office space 6 on each floor can be increased. It can be made an open space with a small number of beams and beams 4.

また、第１構造物２の全体の剛性を低く設定することにより、地震等の外力が第１構造物２に入力した時に、第１構造物２には長周期の振動が生じることになり、後述するように、この第１構造物２の長周期の振動と第２構造物１０に生じる短周期の振動とが制振装置１６で減衰されることにより、第１構造物２の振動が低減される。   In addition, by setting the overall rigidity of the first structure 2 low, when an external force such as an earthquake is input to the first structure 2, long-period vibration is generated in the first structure 2, As will be described later, the vibration of the first structure 2 is reduced by damping the long-period vibration of the first structure 2 and the short-period vibration generated in the second structure 10 by the damping device 16. Is done.

第１構造物２の中心部のボイド空間５は、自然換気を行うための吹き抜け空間、立体駐車設備、エレベータシャフト、空調設備等を設置するための設置空間等として利用される。ボイド空間５の上端開口は、第１構造物２の頂部に設けられる屋根架構７によって閉塞され、上端開口からボイド空間５内に雨水等が浸入するのを防止している。   The void space 5 at the center of the first structure 2 is used as an atrium space for natural ventilation, an installation space for installing a multi-story parking facility, an elevator shaft, an air conditioning facility, and the like. The upper end opening of the void space 5 is closed by a roof frame 7 provided at the top of the first structure 2 to prevent rainwater or the like from entering the void space 5 from the upper end opening.

ボイド空間５を立体駐車設備の設置空間として利用する場合には、立体駐車設備と各階のオフィス空間６との間を壁（図示ず）等を介して遮蔽し、立体駐車設備を各階のオフィス空間６から独立した構造物として機能させる。これにより、立体駐車設備からの騒音や振動等が各階のオフィス空間６に伝達するのを防止できる。   When the void space 5 is used as an installation space for a multilevel parking facility, the space between the multilevel parking facility and the office space 6 on each floor is shielded via a wall (not shown) or the like, and the multilevel parking facility is located on the office space on each floor. 6 to function as a structure independent of 6. Thereby, it can prevent that the noise, vibration, etc. from a multilevel parking facility are transmitted to the office space 6 of each floor.

ボイド空間５をエレベータシャフトの設置空間として利用する場合には、各階のオフィス空間６にボイド空間５を囲むように廊下（図示せず）を設け、廊下を介してエレベータシャフトと各階のオフィス空間６との間を相互に連通し、各階のオフィス空間６から廊下を介してエレベータシャフトに出入り可能に構成する。   When the void space 5 is used as an installation space for the elevator shaft, a corridor (not shown) is provided in the office space 6 on each floor so as to surround the void space 5, and the elevator shaft and the office space 6 on each floor are provided via the corridor. Are connected to each other so that the elevator shaft can enter and exit from the office space 6 on each floor via a corridor.

なお、空調設備等は、ボイド空間５内に設置した立体駐車設備、エレベータシャフト等を利用し、それらの頂部に設置するように構成してもよい。   In addition, you may comprise an air-conditioning installation etc. so that it may install in those tops using the multilevel parking installation installed in the void space 5, an elevator shaft, etc.

第２構造物１０は、第１構造物２よりも剛性を高く設定したラーメン架構の鉄骨構造（Ｓ構造）、コンクリート充填鋼管構造（ＣＦＴ構造）、鉄筋コンクリート構造等の構造物であって、第１構造物２の周囲を所定の間隔をおいて囲み、かつ第１構造物２よりも高さが低く形成されている。本実施の形態においては、第２構造物１０は、第１構造物２の約２／３の高さに形成され、第２構造物１０が第１構造物２の下層階及び中層階に対応するように配置されている。
なお、第２構造物１０は、上記の高さに限らず、第１構造物２と同一、又は第１構造物２よりも高く形成してもよい。 The second structure 10 is a structure having a rigid frame structure (S structure), a concrete-filled steel pipe structure (CFT structure), a reinforced concrete structure, etc., which is set to be higher in rigidity than the first structure 2. The periphery of the structure 2 is surrounded by a predetermined interval, and the height is lower than that of the first structure 2. In the present embodiment, the second structure 10 is formed at a height of about 2/3 of the first structure 2, and the second structure 10 corresponds to the lower floor and the middle floor of the first structure 2. Are arranged to be.
Note that the second structure 10 is not limited to the above height, and may be formed to be the same as the first structure 2 or higher than the first structure 2.

また、本実施の形態においては、第２構造物１０を４つの壁面（第１壁面１２ａ、第２壁面１２ｂ、第３壁面１２ｃ、第４壁面１２ｄ）を有する角筒状に形成し、各壁面（１２ａ〜１２ｄ）を第１構造物２の各外面（第１外面２ａ、第２外面２ｂ、第３外面２ｃ、第４外面２ｄ）に対向させている。   Moreover, in this Embodiment, the 2nd structure 10 is formed in the square cylinder shape which has four wall surfaces (1st wall surface 12a, 2nd wall surface 12b, 3rd wall surface 12c, 4th wall surface 12d), and each wall surface (12a-12d) is made to oppose each outer surface (1st outer surface 2a, 2nd outer surface 2b, 3rd outer surface 2c, 4th outer surface 2d) of the 1st structure 2.

第２構造物１０の各壁面（１２ａ〜１２ｄ）は、鉄骨等を格子状に組み合わせて構成したものであって、このような構成の各壁面（１２ａ〜１２ｄ）を第１構造物２の四隅に対応して立設した柱１１、１１間に設けることにより、全体としての剛性を高く設定することができる。   Each of the wall surfaces (12a to 12d) of the second structure 10 is configured by combining steel frames or the like in a lattice shape, and each of the wall surfaces (12a to 12d) having such a structure is formed at the four corners of the first structure 2. By providing it between the pillars 11 and 11 erected correspondingly, the overall rigidity can be set high.

上記のようにして、第２構造物１０の剛性を高く設定したことにより、地震等の外力が第２構造物２０に入力した時に、第２構造物２０には短周期の振動が生じることになり、後述するように、この第２構造物１０の短周期の振動と第１構造物２の長周期の振動とが制振装置１６で減衰されるにより、第１構造物２の振動が低減される。   As described above, by setting the rigidity of the second structure 10 high, when an external force such as an earthquake is input to the second structure 20, the second structure 20 is vibrated in a short period. Thus, as will be described later, the vibration of the first structure 2 is reduced by the damping device 16 that attenuates the short-period vibration of the second structure 10 and the long-period vibration of the first structure 2. Is done.

なお、第２構造物１０は、上記のような形状に限らず、短周期の振動を生じさせることができる剛性を有する形状であればよい。   In addition, the 2nd structure 10 should just be a shape which has the rigidity which can produce a short period vibration not only in the above shapes.

制振装置１６は、第１構造物２と第２構造物１０との間の隙間１５に介装されて、第１構造物２と第２構造物１０とを相対変位可能に連結する所定の減衰性能を有するものであって、本実施の形態においては、両構造物２、１０間の隙間１５のうち、第１構造物２の各階の外面側の四隅とそれに対応する第２構造物１０の内面側の四隅との間に、平面視Ｖ形状をなすようにそれぞれ一対ずつ介装されている。   The vibration damping device 16 is interposed in a gap 15 between the first structure 2 and the second structure 10 and connects the first structure 2 and the second structure 10 so as to be relatively displaceable. In the present embodiment, among the gaps 15 between the two structures 2 and 10, the four corners on the outer surface side of each floor of the first structure 2 and the second structures 10 corresponding thereto are provided. Each pair is interposed between the four corners on the inner surface side so as to form a V shape in plan view.

制振装置１６は、例えば、オイルダンパー、摩擦ダンパー、粘性ダンパー、粘弾性ダンパー、履歴型ダンパー、又はこれらを組み合わせたものからなり、両端が第１構造物２と第２構造物１０の同一高さ間に連結され、又は、両端が第１構造物２と第２構造物１０の異なる高さ間に連結される。   The vibration damping device 16 is made of, for example, an oil damper, a friction damper, a viscous damper, a viscoelastic damper, a hysteretic damper, or a combination thereof, and both ends thereof are at the same height as the first structure 2 and the second structure 10. The both ends are connected between the different heights of the first structure 2 and the second structure 10.

上記のような構成の本実施の形態の制振構造物１に地震等による外力が入力すると、その外力によって第１構造物２と第２構造物１０とが制振装置１６を介して相対変位する。この場合、第１構造物２は剛性が低く、第２構造物１０は剛性が高く設定されていることにより、第１構造物２には長周期の振動が生じ、第２構造物１０には短周期の振動が生じる。つまり、第１構造物２と第２構造物１０とは異なる振動モードで振動することになり、両者２、１０間に相対変位が生じる。この相対変位に応じて制振装置１６が振動エネルギーを吸収することにより、第１構造物２の振動が低減される。   When an external force due to an earthquake or the like is input to the vibration damping structure 1 of the present embodiment configured as described above, the first structure 2 and the second structure 10 are displaced relative to each other via the vibration damping device 16 due to the external force. To do. In this case, since the first structure 2 has low rigidity and the second structure 10 is set to have high rigidity, long-period vibration is generated in the first structure 2, and the second structure 10 has Short-period vibration occurs. That is, the first structure 2 and the second structure 10 vibrate in different vibration modes, and a relative displacement occurs between the two structures 10. The vibration damping device 16 absorbs vibration energy in accordance with the relative displacement, so that the vibration of the first structure 2 is reduced.

上記のように構成した本実施の形態による制振構造物１にあっては、第１構造物２の柱３、梁４の本数を少なく、柱３、３間のスパンを広くして、第１構造物２の剛性を低く設定したので、第１構造物２の構築に要する費用を大幅に削減することができる。   In the vibration damping structure 1 according to the present embodiment configured as described above, the number of the columns 3 and beams 4 of the first structure 2 is small, the span between the columns 3 and 3 is widened, Since the rigidity of the one structure 2 is set low, the cost required to construct the first structure 2 can be greatly reduced.

また、第１構造物２の各階のオフィス空間６の有効床面積を広く、柱３や梁４の本数の少ない開放的な空間とすることができるので、第１構造物２をオフィス建物６として有効利用することができる。   Moreover, since the effective floor area of the office space 6 on each floor of the first structure 2 can be widened and an open space with a small number of pillars 3 and beams 4 can be formed, the first structure 2 is used as the office building 6. It can be used effectively.

さらに、剛性の低い第１構造物２の外側に剛性の高い第２構造物１０を独立して設けて、第１構造物２と第２構造物１０との間を制振装置１６で連結したので、第１構造物２に耐震補強を施すことなく、第１構造物２の耐震性を高めることができる。   Further, the second structure 10 having high rigidity is independently provided outside the first structure 2 having low rigidity, and the first structure 2 and the second structure 10 are connected by the vibration damping device 16. Therefore, the seismic resistance of the first structure 2 can be enhanced without applying seismic reinforcement to the first structure 2.

図３〜図４には、本発明による制振構造物１の第２の実施の形態が示されていて、図３は全体を示す概略図、図４は図３のＢ−Ｂ線断面図、図５は図３の要部拡大図である。この制振構造物１は、第２構造物１０を、第１構造物２の四隅に対応して設けられる柱１１と、隣接する柱１１、１１間に第１構造物２の各階に対応するように水平に架設される庇１３とによって構成し、各庇１３の端部と第１構造物２の各階の四隅との間に制振装置１６を介装させたものであって、その他の構成は前記第１の実施の形態に示すものと同様である。   3 to 4 show a second embodiment of the vibration damping structure 1 according to the present invention. FIG. 3 is a schematic diagram showing the whole, and FIG. 4 is a sectional view taken along the line BB of FIG. FIG. 5 is an enlarged view of a main part of FIG. In this vibration damping structure 1, the second structure 10 corresponds to each floor of the first structure 2 between the pillars 11 provided corresponding to the four corners of the first structure 2 and the adjacent pillars 11, 11. And the vibration control device 16 is interposed between the end of each of the flanges 13 and the four corners of each floor of the first structure 2. The configuration is the same as that shown in the first embodiment.

上記のように構成した本実施の形態による制振構造物１にあっても、前記第１の実施の形態に示すものと同様の作用効果を奏する他、第２構造物１０の庇１３によって第１構造物２への日射を遮ることができるので、第１構造物２の空調設備の負荷を低減させることができ、省エネルギー化を図ることができる。   Even in the vibration damping structure 1 according to the present embodiment configured as described above, the same effects as those shown in the first embodiment can be obtained, and the second structure 10 can be Since the solar radiation to the 1 structure 2 can be blocked, the load of the air conditioning equipment of the 1st structure 2 can be reduced, and energy saving can be achieved.

また、各庇１３の上部に植栽１４を施すとともに、各庇１３の植栽１４に水を霧状にして供給するシャワーノズル（図示せず）を設置することにより、第１構造物２の外気温を下げることができ、これによっても第１構造物２の空調設備等の負荷を低減させることができ、省エネルギー化を図ることができる。   Moreover, while giving the planting 14 to the upper part of each fence 13, and installing the shower nozzle (not shown) which supplies water to the planting 14 of each fence 13 in mist form, the 1st structure 2 of The outside air temperature can be lowered, and this can also reduce the load on the air conditioning equipment and the like of the first structure 2 and can save energy.

なお、図示はしないが、第２構造物１０を利用してソーラーパネルを取り付け、ソーラーパネルから第１構造物２に電力を供給するように構成してもよい。このように構成することにより、第１構造物２の屋上や屋根等にソーラーパネルの設置スペースを設けることなく、第２構造物１０を利用してソーラーパネルを容易に取り付けることができる。   Although not shown, a solar panel may be attached using the second structure 10 and power may be supplied from the solar panel to the first structure 2.
