Title:
複合ダンパー、粘弾性ダンパー
Document Type and Number:
Japanese Patent JP6749288
Kind Code:
B2
Abstract:
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
