COMPOSITE VIBRATION CONTROL DAMPER FOR STRUCTURE
PROBLEM TO BE SOLVED: To provide a composite vibration control damper for a structure, capable of coping even with displacement by vibration and a temperature change by a strong wind with a simple structure, having durability even in a low cycle fatigue area in earthquake time, and capable of coping with displacement except for the axial direction of a vibration control damper for the structure without using a universal joint.SOLUTION: A composite vibration control damper comprises a first vibration control damper connected to a relatively displacing one structure part and stiffening an axial force member for absorbing energy in earthquake time by elastically-plastically deforming by a buckling restraining member and a second vibration control damper having a cylindrical member connected to the relatively displacing other structure part, a rod member relatively displaceably inserted into the cylindrical member and ring-shaped elastic rubber fixed to an inner peripheral surface of the cylindrical member and forming a hole for inserting the rod member and absorbing relative displacement of the cylindrical member and the rod member by elastic deformation of the elastic rubber by transmitting to the elastic rubber, and the first vibration control damper and the second vibration control damper are connected in series.SELECTED DRAWING: Figure 1
【課題】構造が簡単で強風による振動や温度変化による変位に対しても対応可能で、地震時の低サイクル疲労領域においても耐久性を有し、構造物用制振ダンパーの軸方向以外の変位に対してユニバーサルジョイントを用いることなく対応が可能な構造物用複合制振ダンパーを提供することを目的とする。【解決手段】相対変位する一方の構造部に連結され地震時のエネルギーを弾塑性変形して吸収する軸力部材を座屈拘束部材により補剛した第一の制振ダンパーと、相対変位する他方の構造部に連結される筒状部材と筒状部材に相対変位可能に挿入されるロッド部材と前記筒状部材の内周面に固定され前記ロッド部材を挿通する孔を形成したリング状の弾性ゴムを備え、前記筒状部材と前記ロッド部材の相対変位を前記弾性ゴムに伝達し前記弾性ゴムの弾性変形により吸収する第二の制振ダンパーと、を備え、前記第一の制振ダンパーと前記第二の制振ダンパーを直列に連結することを特徴とする。【選択図】 図１
