VISCOELASTIC BRACE
Document Type and Number:
WIPO Patent Application WO/1999/039064
Kind Code:
A1
Abstract:
A viscoelastic brace, wherein first and second core members comprising shape steel, square steel tubes or circular steel tubes are disposed in series via a pipe expanding and contracting clearance, one set of channel steel or semicircular steel sheets and viscoelastic sheets disposed in opposite positions so as to enclose the first core member therewith being laminated in a single layer on and stuck to a side surface of the first core member, end portions of the channel steel or semicircular steel sheets being fixed to the second core member, whereby the first and second core members are viscoelastically joined to each other via the channel steel or semicircular steel sheets and viscoelastic sheets. This viscoelastic brace enables, in a structure which is higher than it is wide, such as a multistoried building, the horizontal deformation due to an earthquake and wind and a shearing force to be reduced, and vibration to be speedily damped.
