Description

本発明は、高層建物等の屋上などの床面に設置されて地震時等における揺れを抑制するためのチューンド・マス・ダンパーに関するものである。   The present invention relates to a tuned mass damper that is installed on a floor surface such as a rooftop of a high-rise building or the like and suppresses shaking during an earthquake or the like.

近年、強風時や地震時における揺れを抑制するために、屋上にパッシブ制振の一種であるチューンド・マス・ダンパー（Tuned Mass Damper、以下、ＴＭＤと略す。）を設置した高層建物等が多く建設されている。   In recent years, many high-rise buildings with a tuned mass damper (hereinafter abbreviated as TMD), which is a type of passive vibration suppression, are constructed on the roof to suppress shaking during strong winds and earthquakes. Has been.

このＴＭＤは、例えば下記特許文献１に見られるように、上記高層建物等の屋上に錘部材をスプリングおよびダンパーを介して連結するとともに、これらを高層建物等の固有周期に同調するように調整したものである。   This TMD was adjusted so that a weight member was connected to the rooftop of the above-mentioned high-rise building etc. via a spring and a damper, and these were tuned to the natural period of the high-rise building etc. Is.

上記ＴＭＤによれば、電力等のエネルギーを要することなく、安定的に広帯域の振動数範囲の揺れに対して、制振効果を発揮することができるという利点がある。   According to the TMD, there is an advantage that it is possible to stably exhibit a damping effect against a vibration in a wide frequency range without requiring energy such as electric power.

特開２００１−１４１０２６号公報JP 2001-141026 A

しかしながら、上記ＴＭＤにあっては、大地震時に錘部材が非常に大きく変位するために、これに追従できるスプリングおよびダンパーを設計することが難しいという問題点があった。   However, the TMD has a problem that it is difficult to design a spring and a damper that can follow the weight member because the weight member is displaced greatly during a large earthquake.

本発明は、上記事情に鑑みてなされたものであり、スプリングおよびダンパーが錘部材の変位よりも小さな変位によって追従することができ、よってこれらの設計が容易になるとともに、錘部材のストッパー機能も果たすことが可能になるＴＭＤを提供することを課題とするものである。   The present invention has been made in view of the above circumstances, and the spring and the damper can be followed by a displacement smaller than the displacement of the weight member. Therefore, these designs are facilitated, and the stopper function of the weight member is also achieved. It is an object to provide a TMD that can be fulfilled.

上記課題を解決するため、請求項１に記載の本発明に係るＴＭＤは、構造物の床面上に滑り支承または転がり支承を介して水平方向に移動自在に設けられた平面視方形の錘部材と、この錘部材の４側面と上記床面との間に正面視において上記床面に対して傾斜して設けられたスプリングおよびダンパーとを備えてなり、上記スプリングおよび上記ダンパーは、各々上記平面視において上記錘部材の対辺の中心線に対して対称となる位置に配置されるとともに、上端部が上記側面に連結され、かつ下端部が上記スプリングおよび上記ダンパーの延在方向と交差する方向に移動自在に上記床面側に連結されていることを特徴とするものである。   In order to solve the above-mentioned problem, the TMD according to the present invention as set forth in claim 1 is a weight member having a square shape in a plan view provided on a floor surface of a structure so as to be movable in a horizontal direction via a sliding bearing or a rolling bearing. And a spring and a damper provided to be inclined with respect to the floor surface in a front view between the four side surfaces of the weight member and the floor surface. When viewed from the center of the opposite side of the weight member, the upper end is connected to the side surface, and the lower end is in a direction intersecting the extending direction of the spring and the damper. It is connected to the floor surface side so as to be freely movable.

また、請求項２に記載の発明は、請求項１に記載の発明において、上記対称となる位置に配置された上記スプリングは、上記床面との間の傾斜角度が同一になるように設けられ、上記対称となる位置に配置された上記ダンパーは、上記床面との間の傾斜角度が同一になるように設けられていることを特徴とするものである。   According to a second aspect of the present invention, in the first aspect of the present invention, the springs arranged at the symmetrical positions are provided such that the inclination angles with the floor surface are the same. The dampers disposed at the symmetrical positions are provided so as to have the same inclination angle with the floor surface.

請求項１または２に記載の発明によれば、スプリングおよびダンパーを錘部材と床面との間に、床面（水平面）に対して傾斜させて配置しているために、地震時等に錘部材が水平移動する際の移動量よりもスプリングおよびダンパーに生じる伸縮量が小さくなる。このため、上記スプリングやダンパーとしてストロークが小さい汎用のものを用いることができ、設計が容易になるとともに経済性にも優れる。   According to the first or second aspect of the present invention, since the spring and the damper are disposed between the weight member and the floor surface so as to be inclined with respect to the floor surface (horizontal plane), the weight is reduced during an earthquake or the like. The amount of expansion and contraction that occurs in the spring and damper is smaller than the amount of movement when the member moves horizontally. Therefore, a general-purpose spring having a small stroke can be used as the spring or the damper, and the design becomes easy and the economy is excellent.

また、上記スプリングおよびダンパーを、各々平面視において錘部材に対して対称となる位置に配置しているために、錘部材の水平変位が大きくなると、一方の側面に設置したスプリング等は伸びが大きくなるとともに傾きが水平に近づいて反力が上昇し、他方の側面に設置したスプリング等は、縮みつつ鉛直に近づいて反力が低下するために、全体としての反力の大きさの変化が小さく、よって線形と見なせる範囲が大きくなって特性に影響を及ぼすおそれがない。   Further, since the spring and the damper are arranged at positions that are symmetrical with respect to the weight member in plan view, if the horizontal displacement of the weight member is increased, the spring or the like installed on one side has a large elongation. At the same time, the reaction force rises as the inclination approaches horizontal, and the spring installed on the other side shrinks closer to the vertical while shrinking and the reaction force decreases, so the overall change in reaction force is small. Therefore, there is no possibility that the range that can be regarded as linear is increased and the characteristics are not affected.

加えて、上記傾斜角度を適宜設定することにより、剛性や線形域を自由に設定することができる。しかも、錘部材の水平変位がさらに大きくなって、両側のスプリング等の等価周期が非線形域になると、上記スプリング等の反力は増加するために、上記錘部材に対するストッパー機能を奏することも可能になる。   In addition, the rigidity and the linear range can be freely set by appropriately setting the tilt angle. In addition, when the horizontal displacement of the weight member is further increased and the equivalent period of the springs on both sides becomes a non-linear range, the reaction force of the springs and the like increases, so that it is possible to provide a stopper function for the weight member. Become.

また、上記スプリング等の下端部を、当該スプリング等の延在方向と交差するする方向に移動自在となるように床面に連結しているために、上記スプリング等を錘部材の水平Ｘ−Ｙ方向の各々の変位に対して個別に調整することができ、よってＴＭＤを建物の水平Ｘ−Ｙ方向の各周期に同調するように調整することができる。   In addition, since the lower end of the spring or the like is connected to the floor so as to be movable in a direction intersecting the extending direction of the spring or the like, the spring or the like is connected to the horizontal XY of the weight member. It can be adjusted individually for each displacement in direction, so that the TMD can be adjusted to tune to each period in the horizontal XY direction of the building.

さらに、請求項２に記載の発明のように、対称となる位置に配置されたスプリング同士の傾斜角度を等しくし、また上記対称となる位置に配置されたダンパー同士の傾斜角度を等しくすれば、上記線形域の範囲を最も広く確保することが可能になる。   Furthermore, as in the invention described in claim 2, if the inclination angles of the springs arranged at symmetrical positions are made equal, and the inclination angles of the dampers arranged at the symmetrical positions are made equal, It becomes possible to secure the widest range of the linear region.

図１および図２は、本発明に係るＴＭＤの一実施形態を示すもので、図中符号１が錘部材である。
この錘部材１は、平面視方形の板状に形成されたもので、本実施形態においてはキャスター（転がり支承）２によって高層建物の屋上（床面）３にＸ−Ｙ方向に移動自在に設けられている。なお、上記キャスター２に代えて、滑り支承によって錘部材１を屋上３に移動自在に設けてもよい。 1 and 2 show an embodiment of a TMD according to the present invention, and reference numeral 1 in the drawing denotes a weight member.
The weight member 1 is formed in a plate shape having a square shape in plan view. In this embodiment, the weight member 1 is provided on a roof (floor surface) 3 of a high-rise building by a caster (rolling support) 2 so as to be movable in the XY directions. It has been. Instead of the caster 2, the weight member 1 may be movably provided on the roof 3 by sliding support.

そして、この錘部材１のＸ方向に沿う２側面４ａおよびＹ方向に沿う２側面４ｂと屋上３との間に、それぞれスプリング５ａ、５ｂが配設されている。ここで、Ｘ方向に沿う２側面４ａには、各々の角隅部の近傍に２本のスプリング５ａが設けられており、これら２側面４ａに設けられた各２本のプリング５ａは、当該側面４ａに隣接する側面４ｂの対辺１ｂの中心線ＣＹに対して線対称となる位置に配置されている。 Then, springs 5a and 5b are respectively disposed between the two side surfaces 4a along the X direction and the two side surfaces 4b along the Y direction of the weight member 1 and the rooftop 3. Here, the two side surfaces 4a along the X direction are provided with two springs 5a in the vicinity of each corner, and each of the two pullings 5a provided on the two side surfaces 4a is connected to the side surface 4a. is arranged a line symmetry position with respect to the center line C Y opposite sides 1b of adjacent sides 4b to 4a.

また、Ｙ方向に沿う２側面４ｂにも、各々の角隅部の近傍に２本のスプリング５ｂが設けられている。そして、これら２本のスプリング５ｂも、同様に当該側面４ｂに隣接する側面４ａの対辺１ａの中心線ＣＸに対して線対称となる位置に配置されている。 Also, two springs 5b are provided in the vicinity of each corner of the two side surfaces 4b along the Y direction. The two springs 5b are also arranged at positions that are symmetrical with respect to the center line CX of the opposite side 1a of the side surface 4a adjacent to the side surface 4b.

そして、側面４ａ、４ｂと屋上３との間には、これらスプリング５ａ、５ｂの内側に隣接して、各々２本のダンパー６ａ、６ｂが配置されている。これらダンパー６ａ、６ｂも、各々対辺１ｂ、１ａの中心線ＣＹ、ＣＸに対して線対称となるように配置されている。 Two dampers 6a and 6b are disposed between the side surfaces 4a and 4b and the rooftop 3 so as to be adjacent to the inside of the springs 5a and 5b. The dampers 6a and 6b are also arranged so as to be line symmetric with respect to the center lines C Y and C X of the opposite sides 1b and 1a, respectively.

上記スプリング５ａ、５ｂおよびダンパー６ａ、６ｂは、図２に示すように、正面視において床面３との間に同じ角度θを挟んで傾斜して設けられている。そして、これらスプリング５ａ、５ｂおよびダンパー６ａ、６ｂの上端部は、それぞれ側面４ａ、４ｂに連結されている。   As shown in FIG. 2, the springs 5 a and 5 b and the dampers 6 a and 6 b are inclined with the same angle θ between the spring 5 a and 5 b and the dampers 6 a and 6 b when viewed from the front. The upper ends of the springs 5a and 5b and the dampers 6a and 6b are connected to the side surfaces 4a and 4b, respectively.

他方、床面３上の錘部材１から所定間隔をおいた位置には、Ｘ方向およびＹ方向に沿ってレール７ａ、７ｂが固定されており、各レール７ａ、７ｂにスライダー８ａ、８ｂが各レール７に沿ったＸ方向およびＹ方向のみに移動自在に設けられている。そして、これらスライダー８ａ、８ｂに、スプリング５ａ、５ｂおよびダンパー６ａ、６ｂの下端部が連結されている。   On the other hand, rails 7a and 7b are fixed along the X and Y directions at positions spaced from the weight member 1 on the floor surface 3, and the sliders 8a and 8b are respectively attached to the rails 7a and 7b. It is movably provided only in the X direction and the Y direction along the rail 7. The sliders 8a and 8b are connected to the lower ends of the springs 5a and 5b and the dampers 6a and 6b.

以上の構成からなるＴＭＤにおいては、スプリング５ａ、５ｂおよびダンパー６ａ、６ｂを錘部材１と屋上３との間に、屋上３に対して傾斜角度θとなるように傾斜させて配置しているために、地震時等に錘部材１がＸ−Ｙ方向に移動する際の移動量よりもスプリング５ａ、５ｂおよびダンパー６ａ、６ｂに生じる伸縮量が小さくなる。このため、上記スプリング５ａ、５ｂやダンパー６ａ、６ｂとして、ストロークが短い汎用のものを用いることができ、設計が容易になるとともに経済性にも優れる。   In the TMD configured as described above, the springs 5a and 5b and the dampers 6a and 6b are disposed between the weight member 1 and the rooftop 3 so as to be inclined at an inclination angle θ with respect to the rooftop 3. In addition, the amount of expansion and contraction generated in the springs 5a and 5b and the dampers 6a and 6b is smaller than the amount of movement when the weight member 1 moves in the XY direction during an earthquake or the like. For this reason, as the springs 5a and 5b and the dampers 6a and 6b, general-purpose ones having a short stroke can be used, and the design becomes easy and the economy is excellent.

また、スプリング５ａ、５ｂおよびダンパー６ａ、６ｂを、各々平面視において錘部材１の対辺１ａ、１ｂの中心線ＣＹ、ＣＸに対して対称となる位置に配置しているために、図２（ｂ）に示すように、錘部材１の変位が大きくなると、図中左方の側面４ｂに設置したスプリング５ｂ等は伸びが大きくなるとともに傾斜角度が水平に近づいて反力が上昇し、図中右方の側面４ｂに設置したスプリング５ｂ等は、縮みつつ鉛直に近づいて反力が低下するために、全体としての反力の大きさの変化が小さく、よって線形と見なせる範囲が大きくなって特性に影響を及ぼすおそれがない。 Further, since the springs 5a and 5b and the dampers 6a and 6b are arranged at positions symmetrical with respect to the center lines C Y and C X of the opposite sides 1a and 1b of the weight member 1 in plan view, respectively. As shown in (b), when the displacement of the weight member 1 increases, the springs 5b and the like installed on the left side surface 4b in the drawing increase in elongation and the inclination angle approaches horizontal, increasing the reaction force. The springs 5b and the like installed on the middle right side surface 4b approach the vertical while shrinking, and the reaction force decreases, so that the change in the magnitude of the reaction force as a whole is small, and therefore the range that can be regarded as linear becomes large. There is no risk of affecting the properties.

加えて、上記傾斜角度を適宜設定することにより、剛性や線形域を自由に設定することができる。しかも、錘部材の水平変位がさらに大きくなって、両側のスプリング等の等価周期が非線形域になると、上記スプリング等の反力は増加するために、上記錘部材に対するストッパー機能を奏することも可能になる。   In addition, the rigidity and the linear range can be freely set by appropriately setting the tilt angle. In addition, when the horizontal displacement of the weight member is further increased and the equivalent period of the springs on both sides becomes a non-linear range, the reaction force of the springs and the like increases, so that it is possible to provide a stopper function for the weight member. Become.

また、スプリング５ａ、５ｂおよびダンパー６ａ、６ｂの下端部を、スライダー８ａ、８ｂによって屋上３に固定したレール７ａ、７ｂに沿って当該スプリング５ａ、５ｂ等の延在方向と直交する方向に移動自在に設けているために、錘部材１のＸ−Ｙ方向の各々の変位に対してスプリング５ａ、５ｂおよびダンパー６ａ、６ｂを個別に調整することができる。   The lower ends of the springs 5a and 5b and the dampers 6a and 6b are movable in a direction orthogonal to the extending direction of the springs 5a and 5b along rails 7a and 7b fixed to the rooftop 3 by sliders 8a and 8b. Therefore, the springs 5a and 5b and the dampers 6a and 6b can be individually adjusted with respect to each displacement of the weight member 1 in the XY direction.

すなわち、錘部材１のＸ方向の変位に対しては、これによって伸縮するスプリング５ｂおよびダンパー６ｂを調整し、錘部材１のＹ方向の変位に対しては、これによって伸縮するスプリング５ａおよびダンパー６ａを調整することができ、この結果、ＴＭＤを高層建物のＸ−Ｙ方向の各周期に同調するように調整することができる。   That is, the spring 5b and the damper 6b that are expanded and contracted thereby are adjusted with respect to the displacement of the weight member 1 in the X direction, and the spring 5a and the damper 6a that are expanded and contracted with respect to the displacement of the weight member 1 in the Y direction are adjusted. As a result, the TMD can be adjusted to be tuned to each period in the XY direction of the high-rise building.

特に、本実施形態においては、対称となる位置に配置されたスプリング５ａ、５ｂ同士およびダンパー６ａ、６ｂ同士の傾きを、いずれも角度θに設定しているために、上述した線形域の範囲を最も広く確保することができる。ただし、本発明においては、必ずしもスプリングとダンパーとの傾斜角度を同じにしなくてもよい。   In particular, in this embodiment, since the inclinations of the springs 5a and 5b and the dampers 6a and 6b arranged at symmetrical positions are both set to the angle θ, the above-described linear range is set. The most widely secured. However, in the present invention, the inclination angles of the spring and the damper do not necessarily have to be the same.

図３は、錘部材の両側面にＨ＝３．０ｍ、Ｗ＝１．５ｍのスプリングを設けて、錘部材を±２０００ｍｍ水平変位させた際の上記スプリングの引張側および圧縮側の伸縮量を解析した結果を示すものである。図中実線は一方の側面に設けたスプリングの伸縮変化を、点線は他方の側面に設けたスプリングの伸縮変化を示すものである。   FIG. 3 shows the amount of expansion / contraction on the tension side and the compression side of the spring when a spring of H = 3.0 m and W = 1.5 m is provided on both sides of the weight member and the weight member is horizontally displaced by ± 2000 mm. The result of analysis is shown. In the figure, the solid line indicates the expansion / contraction change of the spring provided on one side surface, and the dotted line indicates the expansion / contraction change of the spring provided on the other side surface.

同図に見られるように、錘部材が２０００ｍｍ変位したときのスプリングの伸び量は約１２００ｍｍであり、よって錘部材の変位量よりも伸びが小さい規格のスプリングを用いることができる。   As seen in the figure, the extension amount of the spring when the weight member is displaced by 2000 mm is about 1200 mm. Therefore, a standard spring having a smaller extension than the displacement amount of the weight member can be used.

また、図４は、同様の錘部材が２０００ｍｍ変位したときの等価周期の変化を示すもので、図中実線は一方の側面に設けたスプリングの伸縮変化を、点線は他方の側面に設けたスプリングの伸縮変化を、太実線は両者を合成した変化を示すものである。
同図によれば、合成した等価周期は、錘部材の約±１４００ｍｍの変位の範囲内において線形を示すことが判る。 FIG. 4 shows the change in equivalent period when a similar weight member is displaced by 2000 mm. In the figure, the solid line indicates the expansion / contraction change of the spring provided on one side, and the dotted line indicates the spring provided on the other side. The thick solid line indicates the combined change of the two.
According to the figure, it can be seen that the synthesized equivalent period is linear within a range of displacement of about ± 1400 mm of the weight member.

なお、上記実施形態においては、床面３上のＸ方向およびＹ方向に沿ってレール７ａ、７ｂを固定し、各レール７ａ、７ｂにスライダー８ａ、８ｂを各レール７に沿ったＸ方向およびＹ方向のみに移動自在に設けるとともに、これらスライダー８ａ、８ｂに、スプリング５ａ、５ｂおよびダンパー６ａ、６ｂの下端部を連結した場合についてのみ説明したが、本発明はこれに限定されるものではない。   In the above embodiment, the rails 7a and 7b are fixed along the X direction and the Y direction on the floor surface 3, and the sliders 8a and 8b are fixed to the rails 7a and 7b. Although only the case where the lower ends of the springs 5a and 5b and the dampers 6a and 6b are connected to the sliders 8a and 8b has been described, the present invention is not limited to this.

すなわち、図５は、本発明の他の実施形態を示すもので、このＴＭＤにおいては、床面３上の錘部材１から所定間隔をおいた位置に複数本の支柱１０がＸ方向およびＹ方向に間隔をおいて立設され、これら支柱１０上にＸ方向およびＹ方向に沿ってレール７ａ、７ｂが固定されている。   That is, FIG. 5 shows another embodiment of the present invention. In this TMD, a plurality of support columns 10 are arranged at a predetermined distance from the weight member 1 on the floor surface 3 in the X direction and the Y direction. The rails 7a and 7b are fixed on these columns 10 along the X and Y directions.

これらのレール７ａ、７ｂは、上下面にＸ方向またはＹ方向に沿って溝部が形成された角筒状の部材で、各レール７ａ、７ｂ内にスライダー８ａ、８ｂが各レール７に沿ったＸ方向およびＹ方向のみに移動自在に設けられている。ここで、レール７ａ、７ｂは、スライダー８ａ、８ｂの軸線が錘部材１の重心Ｇと同レベルとなる高さに配置されている。   These rails 7a and 7b are rectangular tube-shaped members in which grooves are formed on the upper and lower surfaces along the X direction or the Y direction. The sliders 8a and 8b are arranged along the rails 7 in the rails 7a and 7b. It is movably provided only in the direction and the Y direction. Here, the rails 7 a and 7 b are arranged at a height at which the axes of the sliders 8 a and 8 b are at the same level as the gravity center G of the weight member 1.

そして、これらスライダー８ａ、８ｂの上面側に、スプリング５ａ、５ｂおよびダンパー６ａ、６ｂの下端部が連結されている。さらに、スライダー８ａ、８ｂの下面側に、他のスプリング５ａ、５ｂおよびダンパー６ａ、６ｂの上端部が連結され、これらスプリング５ａ、５ｂおよびダンパー６ａ、６ｂの下端部が錘部材１の側面４ａ、４ｂの下部に連結されている。   And the lower end part of spring 5a, 5b and damper 6a, 6b is connected with the upper surface side of these sliders 8a, 8b. Furthermore, the upper ends of the other springs 5a and 5b and the dampers 6a and 6b are connected to the lower surface side of the sliders 8a and 8b. It is connected to the lower part of 4b.

上記構成からなるＴＭＤによれば、図１および図２に示したものと同様の作用効果が得られることに加えて、レール７ａ、７ｂが錘部材１の重心Ｇと同レベルに配置されているために、錘部材１の変位に対応して、円滑にスプリング５ａ、５ｂおよびダンパー６ａ、６ｂを作動させることができるという効果も得られる。   According to the TMD configured as described above, the same effects as those shown in FIGS. 1 and 2 can be obtained, and the rails 7 a and 7 b are arranged at the same level as the gravity center G of the weight member 1. Therefore, the effect that the springs 5a and 5b and the dampers 6a and 6b can be operated smoothly in accordance with the displacement of the weight member 1 is also obtained.
