DAMPING DEVICE FOR REDUCING HORIZONTAL VIBRATION DISPLACEMENT CAUSED BY AN EARTHQUAKE LOAD, CAPABLE OF PREVENTING EARTHQUAKE DAMAGE

摘要

PURPOSE: A damping device for reducing horizontal vibration displacement caused by an earthquake load is provided to efficiently reduce horizontal change of an actual building by enhancing a damping effect of a horizontal direction displacement by amplifying minute horizontal direction displacement.;CONSTITUTION: A damping device for reducing horizontal vibration displacement caused by an earthquake load comprises a bar shaped displacement transfer link(110), a displacement amplification link(120), a rotation panel joint(130), and a first damper(140). One end of the displacement transfer link is joined to an edge where a first horizontal panel and a side wall(13) meet. The displacement amplification link comprises a first bean(122), a third beam(126), a second beam(124), a fourth beam(128), and a first panel joint(129a), a second panel joint(129b), a third panel joint(129c), and a fourth panel joint(129d). A first beam is formed in a position facing the first horizontal panel. The third beam is formed in a position facing the second horizontal panel. The second and fourth beams are formed in between the third and first beams. The first panel joint is formed in a position where the first and second beams are connected. The second panel joint is formed in a position where the second and third beams are connected. The third panel joint is formed in a position where the third and fourth beams are connected. The fourth panel joint is formed in a position where the fourth and first beams are connected. The rotation panel joint is fixed to the second horizontal panel and joined to the second panel joint of the displacement amplification link by a hinge. The first damper comprises a body(140a) and a transfer beam(140b).;COPYRIGHT KIPO 2013
