COMPOUND DAMPER, VISCOELASTIC DAMPER
To provide a compound damper which can absorb energy stably from small amplitude to large amplitude and whose installation space is small, and to provide a viscoelastic damper which is mounted on an existing hysteresis damper and which can constitute the compound damper mentioned above.SOLUTION: A compound damper 1 includes a hysteresis damper 3 and viscoelastic dampers 5. The hysteresis damper 3 is arranged between upper and lower beams and it is a stud type in which an energy absorption member 15 is provided between an upper side support member 11 and a lower side support member 13. The viscoelastic damper 5 includes: a steel plate 19 in which a lower end is fixed by rigid connection to a lower beam 9; a thin first viscoelastic body 21 disposed on the steel plate 19; and a thick second viscoelastic body 23 disposed on the steel plate 19 closer to an upper end than the first viscoelastic body 21 and disposed so as to be in series with respect to the first viscoelastic body 21. The viscoelastic dampers 5 are arranged in parallel with both surface and rear surface of the hysteresis damper 3, the first viscoelastic body 21 is bonded to the lower side support member 13, and the second viscoelastic body 23 is bonded to the upper side support member 11.SELECTED DRAWING: Figure 1
【課題】小振幅から大振幅まで安定したエネルギー吸収が可能な複合ダンパーであって、設置スペースが小さい複合ダンパー、及び既存の履歴ダンパーに取り付けられて前記のような複合ダンパーを構成できる粘弾性ダンパーを提供する。【解決手段】本発明に係る複合ダンパー１は、履歴ダンパー３と粘弾性ダンパー５を備え、履歴ダンパー３は、上下の梁間に配置され、上側支持部材１１と下側支持部材１３の間にエネルギー吸収部材１５を設けた間柱型であり、粘弾性ダンパー５は、下端が下梁９に剛接合された鋼板１９と、鋼板１９に配設された薄肉の第１粘弾性体２１と、第１粘弾性体２１よりも上端寄りで、かつ第１粘弾性体２１に対して直列になるように鋼板１９に配設された厚肉の第２粘弾性体２３を有してなり、粘弾性ダンパー５が履歴ダンパー３の表裏両面に並列に配置され、第１粘弾性体２１が下側支持部材１３に接合され、第２粘弾性体２３が上側支持部材１１に接合されている。【選択図】 図１
