Description

本発明は、建築構造物の骨組を構成する鉄骨造柱・梁を地震力等の水平力に抵抗させ、制振することができる耐震構造に関する。   The present invention relates to an earthquake-resistant structure capable of damping a steel column / beam constituting a framework of a building structure by resisting horizontal force such as seismic force.

最近構築される建築構造物は、耐震構造としたものが多い。それに用いられる制振部材についても構成および設置態様が種々あり、その従来例を図１２〜図１３によって説明する。   Many recently built building structures are earthquake-resistant. There are various configurations and installation modes of the vibration damping member used therefor, and conventional examples thereof will be described with reference to FIGS.

図１２（ａ）、（ｂ）、（ｃ）は、制振ブレース１を用いたブレースタイプの制振構造である。この制振ブレース１は、低降伏点鋼からなるエネルギー吸収用芯材を緩衝材（アンボンド材）を介して鋼管等の座屈拘束部材で座屈拘束して構成されている。そして、図（ａ）では、前記の制振ブレース１を鉄骨造の柱２と梁３の軸組みに対角線上に設置している。図（ｂ）では、２本の制振ブレース１を柱２と梁３の軸組みに方杖状に設置している。図（ｃ）では、２本の制振ブレース１を柱２と梁３の軸組みに筋交い状に設置している。   FIGS. 12A, 12 </ b> B, and 12 </ b> C are brace-type damping structures using the damping brace 1. The damping brace 1 is configured by buckling and restraining an energy absorbing core material made of low yield point steel with a buckling restraining member such as a steel pipe via a buffer material (unbond material). And in the figure (a), the said damping brace 1 is installed on the diagonal of the frame structure of the column 2 and the beam 3 of a steel frame. In FIG. 2 (b), two damping braces 1 are installed in the shape of a cane on the shaft 2 and beam 3 shaft assembly. In FIG. 2C, two vibration-damping braces 1 are installed in a bracing manner on the shaft 2 and beam 3 shaft assembly.

図１２（ａ）〜（ｃ）何れの場合も、鉄骨造の柱２と梁３に一定以上の水平力が作用するとき、制振ブレース１に伸長力が作用して、低降伏点鋼からなるエネルギー吸収用芯材が降伏することで、建物の揺れを制するものである。制振ブレース１の構造例としては、特開平１１−２８０２９４号公報や特開２００２−１４６９０５号公報がある。   12 (a) to 12 (c), when a horizontal force of a certain level or more is applied to the steel column 2 and the beam 3, the extension force is applied to the vibration brace 1, and the low yield point steel is used. As the energy absorbing core material yields, it suppresses the shaking of the building. Examples of the structure of the damping brace 1 include Japanese Patent Laid-Open Nos. 11-280294 and 2002-146905.

図１３は、上下階の梁３ａ，３ｂの間に粘弾性ダンパー４を設置した壁タイプの制振構造例を示す。この粘弾性ダンパー４は、建築物の構造骨組に間柱状に設置し、上下階の梁３ａ、３ｂに作用する水平方向の振動を粘弾性ダンパー４に伝えて減衰させている。粘弾性ダンパー４は、上階側の梁３ａから延びた上部分割部材４ａと一体の鋼板５ａと下階側の梁３ｂから延びた下部分割部材４ｂと一体の鋼板５ｂとが交互に噛み合っていて、その間に粘弾性体を装着して構成されている。   FIG. 13 shows an example of a wall-type vibration damping structure in which a viscoelastic damper 4 is installed between the beams 3a and 3b on the upper and lower floors. The viscoelastic damper 4 is installed in a structural frame of a building in a columnar shape, and transmits horizontal vibrations acting on the beams 3a and 3b on the upper and lower floors to the viscoelastic damper 4 to be attenuated. In the viscoelastic damper 4, the upper split member 4a extending from the upper floor side beam 3a and the lower split member 4b extending from the lower floor beam 3b and the integral steel plate 5b are alternately meshed with each other. The viscoelastic body is mounted between them.

図１３の壁タイプの粘弾性ダンパー４によると、鉄骨造の柱２と梁３に一定以上の水平力が作用するとき、その水平力は上下の梁３ａ、３ｂから鋼板５ａ、５ｂを介して粘弾性体６に伝わり、粘弾性６をせん断変形させながら上下の鋼板５ａ、５ｂがずれ動くことで柱、梁接合部７が変位し、柱２と上下の梁３ａ、３ｂと制振間柱４は図１３（ｂ）の２点鎖線のように変形することで、徐々に振動が減衰される。粘弾性ダンパー４の構造例としては、特開２００２−２５６７２８号公報がある。   According to the wall-type viscoelastic damper 4 of FIG. 13, when a horizontal force of a certain level or more acts on the steel-structured column 2 and the beam 3, the horizontal force is transmitted from the upper and lower beams 3a, 3b to the steel plates 5a, 5b. The upper and lower steel plates 5a and 5b are displaced while the viscoelastic body 6 is sheared and deformed, so that the columns and beam joints 7 are displaced, and the columns 2, the upper and lower beams 3a and 3b, and the vibration damping columns 4 are displaced. Is deformed as indicated by a two-dot chain line in FIG. 13B, so that the vibration is gradually attenuated. As a structural example of the viscoelastic damper 4, there is JP-A-2002-256728.

特開平１１−２８０２９４号公報JP-A-11-280294 特開２００２−１４６９０５号公報JP 2002-146905 A 特開２００２−２５６７２８号公報JP 2002-256728 A

図１２、図１３に示した、ブレースタイプや壁タイプの制振部材（エネルギー吸収部材）は、建物の窓などの開口部やドアがある場合は、視覚的、または人が移動する上で邪魔になってしまうため、その場合は、（１）エネルギー吸収部材を設置しないか、（２）ドアの位置をずらすか、（３）エネルギー吸収部材を複雑に設置しなくてはならない。このように、一つの建物において、エネルギー吸収部材を設置できる場所は建築計画上少なく、意匠的にエネルギー吸収部材を見せたくない場合は、エレベータやトイレ、給湯室、階段等のコア部の壁等にしか設置できないため、設計上の自由度が少ないという問題があった。   The brace-type and wall-type damping members (energy absorbing members) shown in FIGS. 12 and 13 are obstructive visually or when a person moves if there are openings or doors such as building windows. In this case, (1) the energy absorbing member is not installed, (2) the position of the door is shifted, or (3) the energy absorbing member is complicatedly installed. In this way, there are few places where an energy absorbing member can be installed in one building because of the architectural plan, and if you do not want to show the energy absorbing member by design, the wall of the core part of the elevator, toilet, hot water room, stairs, etc. Since it can be installed only in the area, there is a problem that the degree of freedom in design is small.

本発明は、前記の問題を解決した建築構造物の制振構造を提供することを目的とする。
An object of the present invention is to provide a vibration damping structure for a building structure that solves the above-described problems.

前記の目的を達成するため本発明は次のように構成した。   In order to achieve the above object, the present invention is configured as follows.

第１発明は、柱、梁で構成される建築構造物の制振構造であって、前記梁に束を設け、この束と前記柱の間に振動エネルギー吸収部材を水平に設置しことを特徴とする。   A first invention is a vibration control structure of a building structure composed of columns and beams, wherein a bundle is provided in the beam, and a vibration energy absorbing member is horizontally installed between the bundle and the column. And

第２発明は、第１発明において、前記振動エネルギー吸収部材は、座屈拘束ブレース、粘弾性体ダンパー、オイルダンパー等のブレース型デバイスであることを特徴とする。   According to a second invention, in the first invention, the vibration energy absorbing member is a brace-type device such as a buckling-restrained brace, a viscoelastic damper, or an oil damper.

第３発明は、第１または第２発明において、前記束は、前記梁の上下両側またはその何れか一方に設け、前記振動エネルギー吸収部材は、前記束の両側または片側と前記柱の間に設置したことを特徴とする。   According to a third invention, in the first or second invention, the bundle is provided on both upper and lower sides of the beam or any one thereof, and the vibration energy absorbing member is installed between both sides or one side of the bundle and the column. It is characterized by that.

第４発明は、第１〜第３発明において、前記振動エネルギー吸収部材は、窓、扉、開口部などの建築部材を回避した部位に設置されていることを特徴とする。   According to a fourth aspect of the present invention, in the first to third aspects, the vibration energy absorbing member is installed at a site avoiding a building member such as a window, a door, or an opening.

第５発明は、第１〜第３発明において、前記振動エネルギー吸収部材は、空調設備が納められたペリメーターゾーンに設置されていることを特徴とする。   According to a fifth invention, in the first to third inventions, the vibration energy absorbing member is installed in a perimeter zone in which an air-conditioning facility is housed.

本発明によると、鉄骨柱・梁構造における柱の中間部位において、梁に束を設け、束を介して柱との間に水平にエネルギー吸収部材を水平に設置し、鉄骨柱・梁に作用する水平力を制振するようにしたので、（１）エネルギー吸収部材が設置可能な場所が多くなり、意匠設計・構造設計の自由度が広がる、（２）束の動きでエネルギー吸収部材の変位を増幅できるので、エネルギー吸収部材を効果的に使用できるものである。
According to the present invention, in the middle part of the column in the steel column / beam structure, the beam is provided with a bundle, and the energy absorbing member is horizontally installed between the column via the bundle and acts on the steel column / beam. Since the horizontal force is controlled, (1) there are many places where the energy absorbing member can be installed, and the degree of freedom in design and structural design is expanded. Since it can be amplified, the energy absorbing member can be used effectively.

次に本発明の実施形態を図を参照して、詳細に説明する。   Next, an embodiment of the present invention will be described in detail with reference to the drawings.

図１（ａ）、（ｂ）は、本発明に係る建築構造物の制振構造の概要図と、地震発生時の構造骨組の減衰作用の説明図である。同図（ａ）には、柱２と梁３が柱、梁接合部７で組まれた構造骨組において、上階の梁３と下階の梁３の各梁のそれぞれの上下側で、かつ、隣り合う柱２の中間位置には束８が設けられていて、束８と柱２との間には本発明に係る振動エネルギー吸収部材１０が設置されていて、これにより建築構造物の制振構造が構築されている。   FIGS. 1A and 1B are a schematic diagram of a vibration damping structure for a building structure according to the present invention and an explanatory diagram of a damping action of a structural frame when an earthquake occurs. In the same figure (a), in the structural framework in which the column 2 and the beam 3 are assembled by the column and the beam joint portion 7, on the upper and lower sides of each beam of the beam 3 on the upper floor and the beam 3 on the lower floor, and A bundle 8 is provided at an intermediate position between the adjacent pillars 2, and a vibration energy absorbing member 10 according to the present invention is installed between the bundle 8 and the pillars 2, thereby controlling the building structure. A vibration structure is built.

前記の制振構造において、鉄骨造の柱２と梁３に一定以上の水平力が作用するとき、柱、梁接合部７が変位して、柱２と上下の梁３は図１（ｂ）の点線のように変形し、このとき、束８と柱２の間に設置した振動エネルギー吸収部材１０には、引張力と圧縮力が交互に作用し、小地震から大地震対して振動エネルギー吸収部材１０における制振部材（詳細は後述する）によりエネルギーを吸収して建物に対する制振作用を奏するものである。   In the above vibration damping structure, when a certain horizontal force is applied to the steel column 2 and the beam 3, the column / beam joint 7 is displaced, and the column 2 and the upper and lower beams 3 are shown in FIG. At this time, the vibration energy absorbing member 10 installed between the bundle 8 and the column 2 is alternately subjected to a tensile force and a compressive force, and absorbs vibration energy from a small earthquake to a large earthquake. Energy is absorbed by a damping member (details will be described later) in the member 10 to exert a damping action on the building.

図２〜図５は、前記振動エネルギー吸収部材１０の設置例を示す側面図で、図２は図１（ａ）と同様に、梁３の上下側に束８を設け、この束８と両側の柱２の間に振動エネルギー吸収部材８を設置した例を示している。図３では、梁３の上側に束８を設け、この束８と両側の柱２の間に振動エネルギー吸収部材１０を設置した例を示している。図４では、梁３の下側に束８を設け、この束８と両側の柱２の間に振動エネルギー吸収部材１０を設置した例を示している。図２〜図４において、束８の左右何れか片側にのみ設置する場合もあるが、図示を省略する。   2 to 5 are side views showing examples of the installation of the vibration energy absorbing member 10, and FIG. 2 is provided with a bundle 8 on the upper and lower sides of the beam 3 as in FIG. The example which installed the vibration energy absorption member 8 between the pillars 2 of this is shown. FIG. 3 shows an example in which a bundle 8 is provided on the upper side of the beam 3 and a vibration energy absorbing member 10 is installed between the bundle 8 and the pillars 2 on both sides. FIG. 4 shows an example in which a bundle 8 is provided below the beam 3 and a vibration energy absorbing member 10 is installed between the bundle 8 and the pillars 2 on both sides. 2 to 4, the bundle 8 may be installed only on one of the left and right sides, but the illustration is omitted.

図２〜図５において、梁３の上部側には、コンクリートのスラブ１１が打設されて上階の床を構成しており、梁３の下部側は下階の天井部を構成している。束８の長さ（高さ）は制限されないが、振動エネルギー吸収部材１０は、建物の窓やドアを設置する部位を回避して設置するという条件がある。この条件を満たすためには振動エネルギー吸収部材１０は、梁３の近くに水平に設置することが求められる。この条件を満たし得るように、束８は、例えばH形鋼等を短寸法に切断したものを梁３に溶接接合して用いられる。   2 to 5, a concrete slab 11 is placed on the upper side of the beam 3 to constitute an upper floor, and the lower side of the beam 3 constitutes a lower floor ceiling. . Although the length (height) of the bundle 8 is not limited, there is a condition that the vibration energy absorbing member 10 is installed avoiding a part where a window or door of a building is installed. In order to satisfy this condition, the vibration energy absorbing member 10 is required to be installed horizontally near the beam 3. In order to satisfy this condition, the bundle 8 is used, for example, by welding a H-shaped steel or the like cut into short dimensions to the beam 3.

また、柱２、梁３に水平力が作用するとき、束８は、Ｏ点（図１ｂ、図２に示す）を中心先端部は左右に揺動し、その揺動が振動エネルギー吸収部材１０に引張力および圧縮力として交互に作用して制振作用が奏される。束８が揺動する際、その揺動ができるだけ増幅されて振動エネルギー吸収部材１０に引張力および圧縮力として伝達されるよう、当該振動エネルギー吸収部材１０は、束８の先端部に固着するのがよい。したがって、束８の先端部に十分な揺動を行わせるために、束８自体は必要な長さ（高さ）を確保するように設けられる。   Further, when a horizontal force is applied to the column 2 and the beam 3, the bundle 8 swings from the O point (shown in FIGS. 1b and 2) to the left and right at the center tip, and the swing is the vibration energy absorbing member 10. A vibration damping action is produced by acting alternately as a tensile force and a compressive force. When the bundle 8 swings, the vibration energy absorbing member 10 is fixed to the tip of the bundle 8 so that the swing is amplified as much as possible and transmitted to the vibration energy absorbing member 10 as a tensile force and a compressive force. Is good. Therefore, the bundle 8 itself is provided so as to ensure a necessary length (height) in order to cause the tip of the bundle 8 to swing sufficiently.

図５には、本発明に係る振動エネルギー吸収部材１０の詳細構造が示されている。同図において、振動エネルギー吸収部材１０は、円筒の被覆鋼管１５で被覆したコンクリート層（図示省略）で低降伏点鋼製のプレートからなる芯材１７が座屈拘束され、芯材１７とコンクリート層の間には、適切な厚さのアンボンド層１８を有するエネルギー吸収本体部１９が構成されている。芯材１７は平板状または十字状でもよい。   FIG. 5 shows a detailed structure of the vibration energy absorbing member 10 according to the present invention. In the figure, a vibration energy absorbing member 10 includes a concrete layer (not shown) covered with a cylindrical coated steel pipe 15 and a core material 17 made of a plate made of low yield point steel is buckled and restrained. An energy absorbing main body 19 having an unbonded layer 18 having an appropriate thickness is formed between the layers. The core member 17 may have a flat plate shape or a cross shape.

さらに、エネルギー吸収本体部１９から露出している芯材１７の端部と柱２及び束３との間はガセットプレートによる接合手段９で接合されている。すなわち芯材１７の端部に固着された第１接合プレート３０と、柱２、束８に固着した第２接合プレート３１の端部同士が突き合わされ、各部材の側面にスプライスプレート２９を当てがいボルト２８で接合されている。   Further, the end portion of the core member 17 exposed from the energy absorbing main body portion 19 and the pillar 2 and the bundle 3 are joined by a joining means 9 using a gusset plate. That is, the first joining plate 30 fixed to the end of the core member 17 and the ends of the second joining plate 31 fixed to the columns 2 and the bundle 8 are abutted with each other, and the splice plate 29 is applied to the side surface of each member. They are joined with bolts 28.

前記の構成において、柱２、梁３に水平力が作用するとき、その水平力による変位が束８の揺動により増幅して振動エネルギー吸収部材１０に伝達され効果的な制振作用を奏する。さらに、所定以上の水平力によって、低降伏点鋼材からなる芯材１７が降伏することで過大な地震等のエネルギーを吸収する。なお、芯材１７を構成する鋼材の降伏応力度に一定の制限があっても、それぞれの断面積及び長さを変えることで、エネルギー吸収能力を自由に設定でき、構造物の形状、架構等に対応するエネルギー吸収能力を得ることができる。   In the above configuration, when a horizontal force acts on the pillar 2 and the beam 3, the displacement due to the horizontal force is amplified by the swing of the bundle 8 and transmitted to the vibration energy absorbing member 10, thereby exhibiting an effective damping action. Furthermore, the energy of an excessive earthquake or the like is absorbed by the yielding of the core material 17 made of a low yield point steel material by a horizontal force of a predetermined level or more. In addition, even if there is a certain restriction on the yield stress of the steel material constituting the core material 17, the energy absorption capacity can be set freely by changing the respective cross-sectional areas and lengths, the shape of the structure, the frame, etc. The energy absorption capability corresponding to can be obtained.

図６〜図１０は、振動エネルギー吸収部材１０と柱２、束８との結合手段を図２〜図５のガセットプレートタイプに代えてピン結合とした例を示す。振動エネルギー吸収部材１０の構成は図２〜図５と同じである。振動エネルギー吸収部材１０の設置態様は、図２と図６、図３と図７、図４と図８が対応する。   6 to 10 show examples in which the coupling means for the vibration energy absorbing member 10 and the columns 2 and the bundle 8 is a pin coupling instead of the gusset plate type of FIGS. The configuration of the vibration energy absorbing member 10 is the same as that shown in FIGS. 2 and 6, FIGS. 3 and 7, and FIGS. 4 and 8 correspond to installation modes of the vibration energy absorbing member 10.

ピン結合部の詳細構造を図９、図１０に示すので以下これを説明する。図１０において、Ｈ形鋼からなる梁３のフランジに、同じくH形鋼からなる束８が立設され溶接１２にて固着されている。両側のフランジの外側には接合板１３が固着されており、両フランジ間にはスチフナ１４が設けられている。   The detailed structure of the pin coupling portion is shown in FIGS. 9 and 10 and will be described below. In FIG. 10, a bundle 8 made of H-shaped steel is also erected on the flange of the beam 3 made of H-shaped steel and fixed by welding 12. A joining plate 13 is fixed to the outside of the flanges on both sides, and a stiffener 14 is provided between the flanges.

振動エネルギー吸収部材１０は、円筒の被覆鋼管１５で被覆したコンクリート層１６で低降伏点鋼製のプレートからなる芯材１７が座屈拘束され、芯材１７とコンクリート層１６の間には、適切な厚さのアンボンド層１８を有するエネルギー吸収本体部１９が構成されている。   In the vibration energy absorbing member 10, a core material 17 made of a plate made of a low yield point steel is buckled and restrained by a concrete layer 16 covered with a cylindrical coated steel pipe 15, and an appropriate gap is provided between the core material 17 and the concrete layer 16. An energy absorbing main body 19 having an unbonded layer 18 with a sufficient thickness is formed.

さらに、エネルギー吸収本体部１９から露出している芯材１７の両端に本体側接合部材２０が設けられ、この本体側接合部材２０は断面十字プレートからなる。本体側接合部材２０には、補助接合体２１における第１接合部２２が溶接１２などにより接合される。補助接合体２１は、さらに第２接合部２３を有し、振動エネルギー吸収部材１０の一端側（図９の例では右端側）においては、第２接合部２３は、束８に設けた接合板１３に連結ピン２４で結合されている。振動エネルギー吸収部材１０の他端側（図９の例では左端側）では、補助接合体２１の第２接合部２３は、柱２に設けた接合板１３と連結ピン２４で結合されている。   Furthermore, main body side joining members 20 are provided at both ends of the core member 17 exposed from the energy absorbing main body portion 19, and the main body side joining member 20 is formed of a cross-shaped cross plate. The first joint portion 22 in the auxiliary joined body 21 is joined to the main body side joining member 20 by welding 12 or the like. The auxiliary joined body 21 further has a second joined portion 23, and the second joined portion 23 is a joined plate provided in the bundle 8 on one end side (right end side in the example of FIG. 9) of the vibration energy absorbing member 10. 13 is connected by a connecting pin 24. On the other end side (the left end side in the example of FIG. 9) of the vibration energy absorbing member 10, the second joint portion 23 of the auxiliary joined body 21 is coupled to the joining plate 13 provided on the column 2 by the connecting pin 24.

ピン結合タイプにおいても、柱２、梁３に水平力が作用するとき、連結ピン２４を介して水平力による変位が束８の揺動により増幅して振動エネルギー吸収部材１０に伝達され効果的な制振作用を奏する。   Also in the pin coupling type, when a horizontal force acts on the pillar 2 and the beam 3, the displacement due to the horizontal force is amplified by the swing of the bundle 8 via the connecting pin 24 and transmitted to the vibration energy absorbing member 10 and effective. Provides vibration control.

図１１（ａ）は、振動エネルギー吸収部材１０を扉２５の設置部位の上方部スペース２７に設置した例を模式図で示す。図１１（ｂ）は、振動エネルギー吸収部材１０を建物外周部において、空調設備を配置するペリメーターゾーン２６に設置した例を示す模式図である。   FIG. 11A schematically shows an example in which the vibration energy absorbing member 10 is installed in the upper space 27 of the installation site of the door 25. FIG. 11B is a schematic diagram showing an example in which the vibration energy absorbing member 10 is installed in the perimeter zone 26 in which the air conditioning equipment is arranged on the outer periphery of the building.

このように、本発明の実施形態によると、振動エネルギー吸収部材１０は、視覚的、または人が移動する上で邪魔にならい場所に設置できるので、（１）扉２５の位置をずらさなくてよい。（２）振動エネルギー吸収部材の設置態様を簡易化できる。（３）その結果、一つの建物における意匠設計・構造設計の自由度が広がる。さらに、（４）束８の動きでエネルギー吸収部材の変位を増幅できるので、振動エネルギー吸収部材１０を効果的に使用できるなどの実用上多くのメリットがある。   As described above, according to the embodiment of the present invention, the vibration energy absorbing member 10 can be installed in a place where it is not disturbed visually or when a person moves, so (1) the position of the door 25 does not have to be shifted. . (2) The installation mode of the vibration energy absorbing member can be simplified. (3) As a result, the degree of freedom of design and structural design in one building is expanded. Further, (4) since the displacement of the energy absorbing member can be amplified by the movement of the bundle 8, there are many practical advantages such as the vibration energy absorbing member 10 being effectively usable.
