Description

本発明は、地震などによって建物に作用した振動エネルギーを減衰させて建物の応答を低減させるための建物の制振構造及びこれを備えた建物に関する。   The present invention relates to a vibration control structure for a building for attenuating vibration energy applied to the building due to an earthquake or the like to reduce the response of the building, and a building including the same.

例えば中高層建物が特大地震を受けると、建物の最弱層に損傷が生じて耐力が低下し始め、この層に地震エネルギー（振動エネルギー）が集中して層崩壊が生じ、他の層は健全性が確保されているにもかかわらず、層崩壊モードによって建物が崩壊に至るという現象が発生する。また、崩壊に至らない場合においても、最弱層の被害が甚大となり、補修による復旧が困難になる。   For example, if a middle- and high-rise building receives an oversized earthquake, the weakest layer of the building will be damaged and the proof stress will begin to decline. Seismic energy (vibration energy) will concentrate on this layer, causing layer collapse, and the other layers will be healthy. However, the phenomenon that the building collapses due to the layer collapse mode occurs. Even if it does not collapse, the damage of the weakest layer will be enormous, making it difficult to recover by repair.

これに対し、従来から、建物の柱と梁で囲まれた架構面内などに種々の制振装置（制振ダンパー、エネルギー吸収機構）を設置することにより地震時や強風時の建物の応答を低減させる対策が多用されている。   In contrast, by installing various vibration control devices (vibration dampers, energy absorption mechanisms) in the frame frame surrounded by the pillars and beams of the building, the response of the building during an earthquake or strong wind has been improved. Countermeasures are often used.

例えば図７に示すように、建物Ｔの架構面Ｔ１内にＶ型ブレース（エネルギー伝達部材）１を設置するとともに、Ｖ型ブレース１と架構（柱（本体柱）２、梁（本体梁）３）にオイルダンパーなどの制振装置４を接続して構成した制振構造Ａが多用されている（例えば、特許文献１参照）。   For example, as shown in FIG. 7, a V-type brace (energy transmission member) 1 is installed in a frame surface T1 of a building T, and a V-type brace 1 and a frame (column (main body column) 2, beam (main body beam) 3). ) Is used frequently (see, for example, Patent Document 1).

そして、このような制振構造Ａを設置した場合には、建物Ｔに振動エネルギーが作用して層間変形が生じると、Ｖ型ブレース１から制振装置４にこの層間変形（変位、振動エネルギー）が伝達され、制振装置４によって振動エネルギーが吸収される。これにより、制振構造Ａによって建物Ｔに作用した振動エネルギーが減衰され、建物Ｔの応答が低減する。   When such a vibration control structure A is installed, if vibration energy acts on the building T and interlayer deformation occurs, the interlayer deformation (displacement, vibration energy) is transferred from the V-type brace 1 to the vibration control device 4. Is transmitted, and vibration energy is absorbed by the damping device 4. Thereby, the vibration energy which acted on the building T by the damping structure A is attenuated, and the response of the building T is reduced.

しかしながら、上記従来の制振構造は、特に建物外周部に取り付けると、ブレースが窓を斜めに遮ることになり、建物内側からの眺望や建物の外観の低下を招き、この点で改善の余地が残されていた。   However, the above-mentioned conventional vibration damping structure, particularly when installed on the outer periphery of the building, causes the brace to block the window diagonally, leading to a view from the inside of the building and a deterioration in the appearance of the building, and there is room for improvement in this respect. It was left.

上記事情に鑑み、本発明は、建物内側からの眺望や建物の外観の低下を招くことなく、建物に優れた耐震性能を付与することを可能にする建物の制振構造及びこれを備えた建物を提供することを目的とする。   In view of the above circumstances, the present invention provides a vibration damping structure for a building and a building equipped with the same, which can impart excellent seismic performance to the building without deteriorating the view from the inside of the building or the appearance of the building. The purpose is to provide.

上記の目的を達するために、この発明は以下の手段を提供している。   In order to achieve the above object, the present invention provides the following means.

本発明の建物の制振構造は、建物の正面視で、建物の本体梁と重なるように横方向に延設されるとともに建物の前記本体梁及び／又は建物の上下方向に延びる本体柱に固設される固定部、及び前記固定部に一端部を接続し、建物の正面視で建物の本体柱と重なるように上下方向に延設された複数の変位伝達部を備えてなり、建物の外周部の外側に配設される複数の変位伝達ユニットと、上下に並設された一対の前記変位伝達ユニットの互いの変位伝達部の自由端である他端部側に両端をそれぞれ接続して建物の外周部の外側に配設される制振装置とを備えて構成され、且つ、建物の任意の一階層を中間層とし、前記中間層よりも上方の上層の本体梁に前記一対の変位伝達ユニットの一方の変位伝達ユニットの固定部を固着し、前記中間層よりも下方の下層の本体梁に他方の変位伝達ユニットの固定部を固着し、前記正面視で前記中間層の本体梁と重なるように前記制振装置を配設して構成されていることを特徴とする。 The vibration damping structure of a building according to the present invention is fixed to the main body beam of the building and / or the main body column extending in the vertical direction of the building and extending in the lateral direction so as to overlap the main body beam of the building in a front view of the building. A fixed portion provided, and one end portion connected to the fixed portion, and a plurality of displacement transmitting portions extending in a vertical direction so as to overlap with a main body column of the building in a front view of the building, A plurality of displacement transmission units disposed outside the unit and a pair of displacement transmission units arranged in parallel above and below the other end side which is the free end of the mutual displacement transmission unit, And a vibration damping device disposed outside the outer peripheral portion of the building, and an intermediate layer is an arbitrary layer of the building, and the pair of displacement transmissions to the upper main body beam above the intermediate layer Fix the fixed part of one displacement transmission unit of the unit from the intermediate layer And characterized in that the lower layer of the body a beam of lower fixing a fixed portion of the other of the displacement transmitting unit is configured by disposing the vibration damping device so as to overlap the body beams of the intermediate layer in the front view To do.

さらに、本発明の建物の制振構造においては、前記固定部が前記本体梁との間に隙間をあけて配設され、一端を前記固定部に他端を前記本体梁に接続して前記隙間に配設された応力伝達部材を備えて構成されていることがより望ましい。   Furthermore, in the vibration damping structure for a building of the present invention, the fixing portion is disposed with a gap between the main body beam, and one end is connected to the fixing portion and the other end is connected to the main body beam. It is more desirable to be provided with the stress transmission member arrange | positioned in.

また、本発明の建物の制振構造においては、前記変位伝達ユニット及び前記制振装置を内包するように配設され、疑似的な建物の柱及び／又は梁を形成する仕上げ用の柱・梁型を備えていることがさらに望ましい。   Further, in the vibration damping structure for a building of the present invention, a finishing column / beam arranged to enclose the displacement transmission unit and the vibration damping device and forming a pseudo building column and / or beam. It is further desirable to have a mold.

本発明の建物は、上記のいずれかの建物の制振構造を備えていることを特徴とする。   A building according to the present invention includes any one of the above-described vibration damping structures.

本発明の建物の制振構造及びこれを備えた建物においては、従来の架構面内に設置するＶ型ブレースなどのブレースを用いず、変位伝達ユニットや、回転慣性質量ダンパー、鋼材ダンパー、オイルダンパー等の制振装置の全てが建物の外周部（本体柱、本体梁）の外側に配置され、且つ建物の正面視で変位伝達ユニットが建物の本体梁や本体柱と重なるように配設されるため、建物の窓からの眺望を妨げることなく、建物の制振性能（耐震性能）を高めることが可能になる。   In the vibration damping structure of a building of the present invention and a building equipped with the same, a displacement transmission unit, a rotary inertia mass damper, a steel damper, and an oil damper are used without using a brace such as a V-type brace installed in a conventional frame. Etc. are all arranged outside the outer periphery of the building (main body column, main body beam), and the displacement transmission unit is arranged so as to overlap the main body beam and main body column of the building in a front view of the building. Therefore, it becomes possible to improve the vibration control performance (seismic performance) of the building without obstructing the view from the window of the building.

また、制振装置に２階層分の層間変形を作用させることができる。このため、従来のように例えばＶ型ブレースと制振装置からなる制振構造を各階層に配置する場合と比較して倍の減衰力を得ることができる。さらに、層をまたいで変形を制御できるので各階層に配置する場合の半分の設置数で同じ制振効果を得ることができる。さらに、これらの相乗効果により、制振装置１台で各階層に２台ずつ計４台配置する場合と同じ制振効果を得ることも可能になる。   Moreover, interlayer deformation for two layers can be applied to the vibration damping device. For this reason, it is possible to obtain double damping force as compared with the conventional case where a vibration damping structure including, for example, a V-type brace and a vibration damping device is arranged in each layer. Furthermore, since the deformation can be controlled across the layers, the same vibration damping effect can be obtained with half the number of installations when arranged in each layer. Furthermore, by these synergistic effects, it becomes possible to obtain the same vibration damping effect as a case where a total of four vibration damping devices are arranged in each hierarchy with one vibration damping device.

よって、本発明の建物の制振構造及びこれを備えた建物によれば、建物内側からの眺望や建物の外観の低下を招くことなく、建物に優れた耐震性能を付与することが可能になる。   Therefore, according to the vibration damping structure of a building of the present invention and a building equipped with the same, it is possible to impart excellent earthquake resistance performance to the building without causing a view from the inside of the building and a deterioration in the appearance of the building. .

以下、図１から図４を参照し、本発明の一実施形態に係る建物の制振構造及びこれを備えた建物について説明する。   Hereinafter, with reference to FIG. 1 to FIG. 4, a vibration damping structure for a building and a building including the same according to an embodiment of the present invention will be described.

本実施形態の建物の制振構造Ｂは、図１に示すように、地震時（あるいは強風時）に例えばオフィスビルやマンションなどの多層構造の建物Ｔに作用した地震エネルギー（振動エネルギー）を吸収して減衰させ、建物Ｔの応答を低減させるためのものであり、この建物Ｔの外周部の外側に設置されている。   As shown in FIG. 1, the building damping structure B of the present embodiment absorbs seismic energy (vibration energy) that acts on a multi-layered building T such as an office building or an apartment building during an earthquake (or during a strong wind). It is for attenuating and reducing the response of the building T, and is installed outside the outer periphery of the building T.

具体的に、本実施形態の制振構造Ｂは、図１から図４に示すように、建物Ｔの外側から建物Ｔの本体柱２及び／又は本体梁３に固着して横方向（梁の材軸方向／延設方向）Ｓ１に沿って配設される複数の固定部５、及び固定部５に一端部を固着して上下方向（柱の材軸方向／延設方向）Ｓ２に沿って配設される複数の変位伝達部６を備えてなり、建物Ｔの外周部の外側に配設される複数の変位伝達ユニット７と、上下に並設された一対の変位伝達ユニット７の互いの変位伝達部の自由端である他端部側に両端をそれぞれ接続して建物Ｔの外側に配設される複数の制振装置８、９とを備えて構成されている。   Specifically, as shown in FIGS. 1 to 4, the vibration damping structure B of the present embodiment is fixed to the main body column 2 and / or the main beam 3 of the building T from the outside of the building T in the lateral direction (the beam direction). Material axis direction / extension direction) A plurality of fixing portions 5 arranged along S1, and one end portion fixed to the fixing portion 5 and along the vertical direction (column axis direction / extension direction) S2. A plurality of displacement transmission units 6 are provided, and a plurality of displacement transmission units 7 arranged outside the outer peripheral portion of the building T and a pair of displacement transmission units 7 arranged vertically are mutually connected. A plurality of vibration control devices 8 and 9 are arranged on the outside of the building T with both ends connected to the other end side which is a free end of the displacement transmitting portion.

本実施形態では、図１に示すように、変位伝達ユニット７の固定部５と変位伝達部６にＨ形鋼などの鉄骨が用いられており、各固定部５は、建物Ｔの正面視（側面視）で、建物Ｔの本体梁３と重なるように横方向Ｓ１に延設され、各変位伝達部６は、建物Ｔの本体柱２と重なるように上下方向Ｓ２に延設されている。   In the present embodiment, as shown in FIG. 1, a steel frame such as H-shaped steel is used for the fixing portion 5 and the displacement transmitting portion 6 of the displacement transmission unit 7, and each fixing portion 5 is a front view of the building T ( In the side view, the displacement transmitting portion 6 extends in the up-down direction S2 so as to overlap with the main body column 2 of the building T.

さらに、各固定部５は、建物Ｔの任意の一階層の中間層を間に上層と下層の本体梁３にそれぞれ重なるように配設されるとともに、横方向Ｓ１に隣り合う３本の本体柱２に両端部と中央部をそれぞれ固着して配設されている。また、図３に示すように、本実施形態の固定部５は、本体梁３との横方向Ｓ３に適度な隙間をあけて設置され、一端を固定部５に、他端を本体梁３に接続して隙間内に複数のブレース１０が設置されている。これにより、変位伝達ユニット７の固定部５は、中間部分がブレースなどの応力伝達部材１０を介して本体梁３に接続され、建物Ｔに作用した振動エネルギー（層間変位）が確実に建物Ｔから伝達されるように配設されている。   Further, each fixing portion 5 is arranged so as to overlap an upper layer and a lower layer main body beam 3 between any one intermediate layer of the building T, and three main body columns adjacent to each other in the lateral direction S1. 2, both end portions and the central portion are fixedly disposed. Further, as shown in FIG. 3, the fixing portion 5 of the present embodiment is installed with an appropriate gap in the lateral direction S3 with the main body beam 3, one end being the fixing portion 5 and the other end being the main body beam 3. A plurality of braces 10 are installed in the gap. Thereby, the fixed part 5 of the displacement transmission unit 7 is connected to the main body beam 3 via the stress transmission member 10 such as a brace, and the vibration energy (interlayer displacement) acting on the building T is reliably transmitted from the building T. It is arranged to be transmitted.

また、本実施形態の変位伝達ユニット７は、図１に示すように、１本の固定部５に対して３本の変位伝達部６を取り付けて形成され、２本の変位伝達部６が固定部５の両端側にそれぞれ一端部（上端部）を固着して下方に垂設され、１本の変位伝達部６が固定部５の中央部に一端部（下端部）を固着して上方に延設されている。   In addition, as shown in FIG. 1, the displacement transmission unit 7 of this embodiment is formed by attaching three displacement transmission parts 6 to one fixed part 5, and the two displacement transmission parts 6 are fixed. One end portion (upper end portion) is fixed to both ends of the portion 5 so as to hang downward, and one displacement transmitting portion 6 has one end portion (lower end portion) fixed to the center portion of the fixing portion 5 and upward. It is extended.

一方、制振装置８、９は、図１から図４に示すように、例えば回転慣性質量ダンパー、オイルダンパー、鋼材ダンパー等であり、上下に並設された一対の変位伝達ユニット７の互いの変位伝達部６（横方向Ｓ１に隣り合う一対の変位伝達部６）の自由端である他端部に両端部をそれぞれ接続して建物Ｔの外周部の外側に架設されている。   On the other hand, as shown in FIGS. 1 to 4, the vibration damping devices 8 and 9 are, for example, a rotary inertia mass damper, an oil damper, a steel damper, and the like. Both ends are respectively connected to the other end which is a free end of the displacement transmission unit 6 (a pair of displacement transmission units 6 adjacent to each other in the lateral direction S1) and are installed outside the outer peripheral portion of the building T.

より具体的に、本実施形態において、制振装置８、９は、建物Ｔの正面視（側面視）で、建物Ｔの中間層を間にした上層と下層の本体梁３に沿って配設された上方の変位伝達ユニット７の固定部５に一端部を接続して垂設された変位伝達部６の他端部と、下方の変位伝達ユニット７の固定部５に一端部を接続して上方に延設された変位伝達部６の他端部とにそれぞれ両端部を接続し、中間層の本体梁３に沿って横方向Ｓ１に軸方向を向けて配設されている。   More specifically, in the present embodiment, the vibration damping devices 8 and 9 are disposed along the upper and lower body beams 3 with the intermediate layer of the building T in between when the building T is viewed from the front (side view). One end portion is connected to the fixed portion 5 of the upper displacement transmission unit 7 and the other end portion of the displacement transmission portion 6 is suspended by being connected to one end portion, and one end portion is connected to the fixed portion 5 of the lower displacement transmission unit 7. Both end portions are respectively connected to the other end portion of the displacement transmitting portion 6 extending upward, and are disposed along the intermediate body beam 3 in the lateral direction S1 in the axial direction.

さらに、本実施形態では、上方の変位伝達ユニット７の固定部５の横方向Ｓ１一端側に配設された変位伝達部６の他端部と、下方の変位伝達ユニット７の固定部５の横方向Ｓ１中央部に配設された変位伝達部６の他端部にそれぞれ両端部を接続して回転慣性質量ダンパー及び付加ばねを備えてなる制振装置９を設置している。また、上方の変位伝達ユニット７の固定部５の横方向Ｓ１他端側に配設された変位伝達部６の他端部と、下方の変位伝達ユニット７の固定部５の横方向Ｓ１中央部に配設された変位伝達部６の他端部にそれぞれ両端部を接続してオイルダンパーの制振装置８を設置している。すなわち、異なる種類の制振装置８、９を並設して制振構造Ｂが構成され、この場合には各制振装置８、９の性能、特長を活かし、効果的に制振性能の向上を図ることが可能になる。   Furthermore, in the present embodiment, the other end of the displacement transmitting portion 6 disposed on one end side in the lateral direction S1 of the fixing portion 5 of the upper displacement transmission unit 7 and the side of the fixing portion 5 of the lower displacement transmitting unit 7 are arranged. A vibration damping device 9 including a rotary inertia mass damper and an additional spring is installed by connecting both ends to the other end of the displacement transmission unit 6 disposed in the center of the direction S1. Further, the other end of the displacement transmitting portion 6 disposed on the other end side in the lateral direction S1 of the fixing portion 5 of the upper displacement transmission unit 7 and the central portion of the lateral direction S1 of the fixing portion 5 of the lower displacement transmitting unit 7. An oil damper damping device 8 is installed by connecting both ends to the other end of the displacement transmitting portion 6 disposed in the cylinder. That is, the damping structure B is configured by arranging different types of damping devices 8 and 9 in parallel. In this case, the performance and characteristics of each damping device 8 and 9 are utilized to effectively improve the damping performance. Can be achieved.

ここで、本実施形態のように制振装置９（減衰装置）として回転慣性質量ダンパー等の質量系のダンパーを用いる場合には、変位伝達ユニット７の剛性を、質量系ダンパーを建物の固有周期と同調させるためのバネ、又はバネの一部として活用することが可能である。このため、本実施形態において、変位伝達ユニット７がバネとして働く場合は、制振装置９から構成要素として付加ばねをなくすことも可能である。   Here, when a mass damper such as a rotary inertia mass damper is used as the damping device 9 (attenuator) as in the present embodiment, the rigidity of the displacement transmission unit 7 is set to the natural period of the building. It is possible to utilize as a spring for synchronizing with, or a part of the spring. For this reason, in this embodiment, when the displacement transmission unit 7 works as a spring, it is possible to eliminate the additional spring as a component from the vibration damping device 9.

さらに、本実施形態の建物の制振構造Ｂ及び建物Ｔにおいては、図２から図４に示すように、変位伝達ユニット７及び制振装置８、９を内包するように配設され、疑似的な建物Ｔの柱及び／又は梁を形成する仕上げ用の柱・梁型１１を備えている。これにより、建物Ｔの外周部の外側に変位伝達ユニット７や制振装置８、９を設置するようにしても、仕上げ用の柱・梁型１１によって建物Ｔの外観を好適に確保することができる。   Furthermore, in the building damping structure B and the building T of the present embodiment, as shown in FIGS. 2 to 4, the displacement transmitting unit 7 and the damping devices 8 and 9 are disposed so as to be pseudo. A finishing column / beam type 11 for forming a column and / or beam of a simple building T is provided. Thereby, even if the displacement transmission unit 7 and the vibration control devices 8 and 9 are installed outside the outer peripheral portion of the building T, the appearance of the building T can be suitably secured by the finishing column / beam type 11. it can.

上記構成からなる本実施形態の建物の制振構造Ｂ（及びこれを備えた建物Ｔ）においては、地震や強風などによって建物Ｔに振動エネルギーが作用した際に、建物Ｔの本体梁３や本体柱２の層間変形に応じて変位伝達ユニット７の固定部５及び変位伝達部６が変位し、これら部材の変位が制振装置８、９に伝達され、振動エネルギーが吸収される。   In the building damping structure B (and the building T including the same) of the present embodiment having the above-described configuration, when vibration energy acts on the building T due to an earthquake or a strong wind, the main beam 3 and the main body of the building T The fixed portion 5 and the displacement transmission portion 6 of the displacement transmission unit 7 are displaced according to the interlayer deformation of the column 2, and the displacement of these members is transmitted to the vibration control devices 8 and 9, and the vibration energy is absorbed.

これにより、確実に制振装置８、９に層間変位（振動エネルギー）が伝達されて吸収され、建物Ｔの応答を低減させることが可能になる。   Thereby, the interlayer displacement (vibration energy) is reliably transmitted to and absorbed by the vibration damping devices 8 and 9, and the response of the building T can be reduced.

したがって、本実施形態の建物の制振構造Ｂ及びこれを備えた建物Ｔにおいては、従来の架構面Ｔ１内に設置するＶ型ブレースなどのブレースを用いず、変位伝達ユニット７や、回転慣性質量ダンパー、鋼材ダンパー、オイルダンパー等の制振装置８、９の全てが建物Ｔの外周部（本体柱２、本体梁３）の外側に配置され、且つ建物Ｔの正面視で変位伝達ユニット７が建物Ｔの本体梁３や本体柱２と重なるように配設されるため、建物Ｔの窓からの眺望を妨げることなく、建物Ｔの制振性能（耐震性能）を高めることが可能になる。   Therefore, in the vibration damping structure B of the present embodiment and the building T equipped with the same, the displacement transmission unit 7 and the rotary inertia mass are not used without using a brace such as a V-type brace installed in the conventional frame surface T1. Damping devices 8, 9 such as dampers, steel dampers, and oil dampers are all disposed outside the outer periphery of the building T (main body column 2 and main body beam 3), and the displacement transmission unit 7 is viewed from the front of the building T. Since it arrange | positions so that the main body beam 3 and the main body pillar 2 of the building T may overlap, it becomes possible to improve the damping performance (seismic performance) of the building T, without disturbing the view from the window of the building T.

また、制振装置８、９に２階層分の層間変形を作用させることができる。このため、従来のように例えばＶ型ブレースと制振装置からなる制振構造Ａを各階層に配置する場合と比較して倍の減衰力を得ることができる。さらに、層をまたいで変形を制御できるので各階層に配置する場合の半分の設置数で同じ制振効果を得ることができる。さらに、これらの相乗効果により、制振装置１台で各階層に２台ずつ計４台配置する場合と同じ制振効果を得ることも可能になる。   Moreover, the interlayer deformation for two layers can be applied to the vibration control devices 8 and 9. For this reason, a double damping force can be obtained as compared with the case where the vibration damping structure A composed of, for example, a V-type brace and a vibration damping device is arranged in each layer as in the prior art. Furthermore, since the deformation can be controlled across the layers, the same vibration damping effect can be obtained with half the number of installations when arranged in each layer. Furthermore, by these synergistic effects, it becomes possible to obtain the same vibration damping effect as a case where a total of four vibration damping devices are arranged in each hierarchy with one vibration damping device.

よって、本実施形態の建物の制振構造Ｂ及びこれを備えた建物Ｔによれば、建物Ｔ内側からの眺望や建物Ｔの外観の低下を招くことなく、建物Ｔに優れた耐震性能を付与することが可能になる。   Therefore, according to the vibration damping structure B of the building of this embodiment and the building T equipped with the same, the building T is provided with excellent seismic performance without causing a view from the inside of the building T and a deterioration in the appearance of the building T. It becomes possible to do.

また、変位伝達ユニット７や制振装置８、９を仕上げ用の柱・梁型１１で囲うことにより、確実に建物Ｔの外観を好適に確保することが可能になる。   In addition, by enclosing the displacement transmission unit 7 and the vibration damping devices 8 and 9 with the finishing column / beam type 11, it is possible to reliably ensure the appearance of the building T.

さらに、変位伝達ユニット７の固定部５と建物Ｔの本体梁３を応力伝達部材１０で接続することにより、応力伝達部材１０で水平力を確実に伝達させることが可能になるとともに、制振構造Ｂと本体柱２、本体梁３との距離によって生じる偏芯モーメントに対して抵抗させることができる。これにより、地震や強風などによって建物Ｔに作用した振動エネルギー、層間変位を効率的且つ効果的に変位伝達ユニット７、ひいては制振装置８、９に伝達することができる。よって、より確実且つ効果的に建物Ｔの制振性能を高めることが可能になる。なお、本実施形態では応力伝達部材１０がブレースであるように図示しているが、本発明に係る応力伝達部材は水平力を確実に伝達させることが可能になるとともに、制振構造Ｂと本体柱２、本体梁３との距離によって生じる偏芯モーメントに対して抵抗させることが可能であればよく、ブレースに限定する必要はない。   Further, by connecting the fixed portion 5 of the displacement transmission unit 7 and the main beam 3 of the building T with the stress transmission member 10, it is possible to reliably transmit the horizontal force with the stress transmission member 10, and to provide a vibration damping structure. It is possible to resist the eccentric moment generated by the distance between B, the main body column 2 and the main body beam 3. Thereby, the vibration energy and the interlaminar displacement which acted on the building T by an earthquake, a strong wind, etc. can be transmitted to the displacement transmission unit 7 and by extension, the damping devices 8 and 9 efficiently and effectively. Therefore, it becomes possible to improve the vibration control performance of the building T more reliably and effectively. In this embodiment, the stress transmission member 10 is illustrated as a brace. However, the stress transmission member according to the present invention can reliably transmit a horizontal force, and the damping structure B and the main body. It is only necessary to be able to resist the eccentric moment caused by the distance between the column 2 and the main body beam 3, and it is not necessary to limit to the brace.

また、制振装置９として回転慣性質量ダンパーを用い、建物Ｔの周期と同調させることにより、変位伝達ユニット７の剛性を同調用のバネまたはバネの一部として使用することができる。これにより、さらに確実且つ効果的に、建物Ｔの制振性能を高めることが可能になる。   Further, by using a rotary inertia mass damper as the vibration damping device 9 and synchronizing with the period of the building T, the rigidity of the displacement transmission unit 7 can be used as a tuning spring or a part of the spring. Thereby, it becomes possible to improve the vibration control performance of the building T more reliably and effectively.

さらに、既存建物Ｔに制振構造Ｂを設けて耐震改修を行う場合においても、建物外部での工事が主であるので、建物Ｔの入居者、使用者に対する影響が少ない。よって、好適に既存建物Ｔの耐震改修を行うことが可能になる。   Further, even when the existing structure T is provided with the vibration control structure B and the earthquake-resistant repair is performed, the construction outside the building is mainly performed, and therefore the influence on the residents and users of the building T is small. Therefore, it becomes possible to perform the earthquake-proof repair of the existing building T suitably.

以上、本発明に係る建物の制振構造及びこれを備えた建物の一実施形態について説明したが、本発明は上記の一実施形態に限定されるものではなく、その趣旨を逸脱しない範囲で適宜変更可能である。   As mentioned above, although one embodiment of the vibration damping structure of the building which concerns on this invention, and a building provided with this was described, this invention is not limited to said one embodiment, In the range which does not deviate from the meaning, it is appropriate. It can be changed.

例えば、図５に示すように、一端、中間部、他端を本体梁３及び／又は本体柱２に固着して横方向ｓ１に延設される固定部５と、固定部５の一端側に一端部（下端部）を接続して上方に延設される変位伝達部６と、固定部５の他端側に一端部（上端部）を接続して下方に垂設される変位伝達部６を備えて変位伝達ユニット７を形成するとともに、上下に配設された複数の変位伝達ユニット７の変位伝達部６の自由端である他端部に両端部をそれぞれ接続して制振装置８、９を設置して、建物の制振構造Ｂを構成するようにしてもよい。   For example, as shown in FIG. 5, one end, an intermediate portion, and the other end are fixed to the main body beam 3 and / or the main body column 2, and the fixing portion 5 is extended in the lateral direction s 1. Displacement transmission unit 6 connected to one end (lower end) and extending upward, and displacement transmission unit 6 connected to one end (upper end) on the other end side of fixing unit 5 and suspended downward. And forming a displacement transmission unit 7, and connecting both ends to the other end, which is the free end of the displacement transmission unit 6 of the plurality of displacement transmission units 7 disposed above and below, 9 may be installed to constitute the building damping structure B.

この場合においても、本実施形態と同様、建物Ｔの層間変形により変位伝達部６に生じる曲げモーメントを、これを接続した固定部５で抵抗させて受けることができる。これにより、確実に制振装置８、９で振動エネルギーを吸収させ、建物Ｔの応答を低減させることが可能になる。   Also in this case, as in the present embodiment, the bending moment generated in the displacement transmitting portion 6 due to the interlayer deformation of the building T can be received by being resisted by the fixed portion 5 to which the bending moment is connected. Thereby, it is possible to reliably absorb the vibration energy by the vibration control devices 8 and 9 and reduce the response of the building T.

また、図６に示すように、一端、中間部、他端を本体梁３及び／又は本体柱２に固着して横方向Ｓ１に延設された固定部５と、固定部５の一端側に一端部（下端部）を接続して上方に延設された変位伝達部６と、固定部５の他端側に一端部（上端部）を接続して下方に垂設された変位伝達部６と、固定部５の中間部に所定の間隔をあけ、それぞれ一端部（上端部又は下端部）を接続して上方あるいは下方に延設された変位伝達部６を備えて変位伝達ユニット７を形成するとともに、上下に配設された複数の変位伝達ユニット７の隣り合う変位伝達部６の他端部に両端部をそれぞれ接続して制振装置８、９を設置して、建物の制振構造Ｂを構成するようにしてもよい。   Further, as shown in FIG. 6, one end, an intermediate portion, and the other end are fixed to the main body beam 3 and / or the main body column 2 and extended in the lateral direction S <b> 1; A displacement transmission portion 6 that extends upward by connecting one end portion (lower end portion), and a displacement transmission portion 6 that extends downward by connecting one end portion (upper end portion) to the other end side of the fixed portion 5. A displacement transmission unit 7 is formed by providing a displacement transmission part 6 with a predetermined interval in the middle part of the fixed part 5 and connecting one end part (upper end part or lower end part) and extending upward or downward. In addition, the vibration control devices 8 and 9 are installed by connecting both ends to the other ends of the adjacent displacement transmission units 6 of the plurality of displacement transmission units 7 arranged above and below, and the vibration damping structure of the building B may be configured.

そして、このように制振構造Ｂを構成する場合においても、建物Ｔの層間変形により変位伝達部６に生じる曲げモーメントを、これを接続した固定部５で抵抗させて受けることができる。これにより、確実に制振装置８、９で振動エネルギーを吸収させ、建物Ｔの応答を低減させることが可能になる。   Even when the vibration damping structure B is configured as described above, the bending moment generated in the displacement transmitting portion 6 due to the interlayer deformation of the building T can be received by being resisted by the fixed portion 5 to which the displacement transmitting portion 6 is connected. Thereby, it is possible to reliably absorb the vibration energy by the vibration control devices 8 and 9 and reduce the response of the building T.

また、図５に示した変位伝達ユニット７（制振構造Ｂ）を、本実施形態や図７に示すように軸対称に展開してゆくことで、任意のスパン（柱間長さ、固定部５の長さ）での部材配置が可能になる。   Further, by expanding the displacement transmission unit 7 (damping structure B) shown in FIG. 5 in an axially symmetrical manner as shown in this embodiment and FIG. 7, any span (length between columns, fixed portion) 5) can be arranged.
