Abstract
Description
本発明は建築耐震技術分野を取り上げて、具体的には単振り子ー粘性液体連合ダンパーである。 The present invention covers the field of building seismic technology, specifically a single pendulum-viscous liquid combined damper.
高層建築、特に１５０ｍを超えた超高層建築は、水平方向での荷重効果が著しく、そのため風荷重と、地震荷重が構造デザインの主要なコントロール要素である。風荷重と地震荷重がいすれもランダム荷重であり、構造振動を引き起こし、構造にダンパーなどの適合な減衰装置を装着することにより構造振動の影響を有効に下がらせることができ（例えば構造の層間横変位、頂部変位、頂部加速度、土台転覆曲げモーメントとトルクなど）、それにより構造の耐風と耐震の性能が上げられる。
常用のダンパーがTMD（Tuned Mass Damper チューニング質量ダンパー）とTLD（Tuned Liquid Damper チューニング液体ダンパー）。普通の場合には、TMDあるいはTLDシステムの一階固有振動数が構造総体の一階固有振動数と比較的に近いことを必要とし、且つTMDあるいはTLDシステムの質量が十分に大きいことを必要とし、それにより主体構造の振動位相と逆であって十分に大きな振動が生み出され、このようにTMDあるいはTLDシステムは振動が主体構造に対して生じた力により主体構造振動の振り幅を有効に抑制することができ、そこからエネンルギー消散と減衰の効果ができる。但し通常のTMDあるいはTLDシステムは下記の問題が往往にしてある：（１）TLDシステムは構造の水平方向の振動に対してより効果的に抑制するには一般により大きい質量が必要であり、、特に構造の総質量が比較的に高い高層建築に対しては、巨大な容器でなければ十分の溶体を収容することができなく、スペースを占用する他、施工も不便である；（２）TMDシステムが比較的に大きい質量を必要とし、TMD質量は主体構造の質量の１％ぐらいに達しなければ、よりよく振動抑制の効果ができないと普通に考えられ、しかし大きすぎる質量がホスティング工事に大きな困難をもたらし、その同時に構造総体のリスクが増加される；（３）現有のTMDシステムは一般に上部が吊りバーを主体構造と接続させ、下部が金属制動連接棒を利用しサポートとし、且つ金属制動連接棒が下部の構造と接続され（例えば台北の１０１建物のTMDの振動コントロールシステム）、このようなシステムの機械構造が比較的に複雑であり、建造コストと、メンテナンスコストがいずれもより高い。
Tall buildings, especially skyscrapers over 150m, have a significant horizontal loading effect, so wind and seismic loads are the main control elements of structural design. Both wind and seismic loads are random loads, which can cause structural vibrations and reduce the effects of structural vibrations effectively by installing suitable damping devices such as dampers on the structure (for example, the structure Displacement, top displacement, top acceleration, base overturning bending moment and torque, etc., thereby improving the wind and seismic performance of the structure.
Common dampers are TMD (Tuned Mass Damper Tuning Mass Damper) and TLD (Tuned Liquid Damper Tuning Liquid Damper). In the normal case, the first order natural frequency of the TMD or TLD system needs to be relatively close to the first order natural frequency of the structural body, and the mass of the TMD or TLD system needs to be sufficiently large. , Thereby producing a sufficiently large vibration that is opposite to the vibration phase of the main structure. In this way, the TMD or TLD system effectively suppresses the amplitude of the main structure vibration by the force generated by the vibration on the main structure Which can have the effect of energy dissipation and attenuation. However, conventional TMD or TLD systems suffer from the following problems: (1) TLD systems generally require a higher mass to more effectively suppress the horizontal vibration of the structure; Especially for high-rise buildings where the total mass of the structure is relatively high, a large container cannot accommodate enough solution, occupies space and is inconvenient to construct; (2) TMD If the system requires a relatively large mass, and the TMD mass does not reach about 1% of the mass of the main structure, it is generally considered that the effect of vibration suppression cannot be improved, but too large mass is large for hosting work. Presents difficulties and at the same time increases the risk of the overall structure; (3) existing TMD systems generally use a suspension bar connected to the main structure at the top and support using metal brake connecting rods at the bottom. In addition, the metal brake connecting rod is connected to the lower structure (for example, the vibration control system of TMD of 101 building in Taipei), the mechanical structure of such system is relatively complicated, and both the construction cost and the maintenance cost are low. Also higher.

本発明のメリット： Advantages of the present invention:
単振り子質量ブロックと粘性液体を利用して連合組み合わせて高層建築の振動をコントロールするダンパーシステムは、単振り子システムの逆方向の振動を利用し主体構造の振動エネルギーを転移した他、また単振り子質量ブロックと粘性液体との間の摩擦及び粘性液体と容器壁との間の摩擦を利用してエネルギーを消費し、そこからエネルギー消費の手段が増え、ダンパーシステムが主体構造の振動を抑制する効果を強めることができる。 The damper system, which controls the vibration of a high-rise building by combining a single pendulum mass block and a viscous liquid, is used to transfer the vibration energy of the main structure using the vibration of the single pendulum system in the opposite direction.

本発明の中に発生した単振り子質量ブロックと粘性液体との間の摩擦及び粘性液体と容器壁との間の摩擦がいずれも固体と液体との間の摩擦であり、普通の摩擦振り子ダンパーが固体と固体との間の摩擦を利用してエネルギーを消費することより、本ダンパーは仕事している時にあまり騒音が出なく、利用者に対する妨碍がより小さく、利用者がより楽に利用できる。 The friction between the single pendulum mass block and the viscous liquid and the friction between the viscous liquid and the container wall generated in the present invention are both the friction between the solid and the liquid, and the ordinary friction pendulum damper is used. By consuming energy using the friction between solids, the damper produces less noise when working, has less obstruction to the user, and is more comfortable for the user.

本発明の働き原理は：高層建物構造は風あるいは地震の作用により水平横向きの振動が発生する時、単振り子がそれにより揺れ動き、単振り子のダンパー固有振動数が主体構造の土台と段階の固有振動数に近づく時、主体構造と逆位相の振動が発生することができ、そこから主体構造の振動エネルギーを単振り子システムに転移し；その同時に、本発明の中には、液体容器の中に盛られた液体は単振り子が揺れ動いている時に、粘性有機液体と単振り子質量ブロックとの間には摩擦が発生しエネルギーも消費することができ、その同時に粘性有機液体自体の揺れ動きと液体容器壁との間の摩擦がエネルギーを消費することができるため、エネルギー消費の手段が増え、システムの主体構造の振動を抑制する効率が上がる。 The working principle of the present invention is: When a high-rise building structure generates horizontal and horizontal vibrations due to the action of wind or earthquake, the simple pendulum swings by it, and the natural frequency of the damper of the simple pendulum is based on the main structure and the natural vibration of the stage When approaching a number, vibrations in phase opposition to the main structure can be generated, from which the vibration energy of the main structure is transferred to a single pendulum system; When the simple pendulum is oscillating, friction occurs between the viscous organic liquid and the single pendulum mass block, and energy can be consumed.At the same time, the viscous organic liquid itself oscillates and the liquid container wall Can consume energy, so that the means of energy consumption increases and the efficiency of suppressing vibration of the main structure of the system increases.
