Title:
HIGH-PERFORMANCE SHEAR FRICTION DAMPER
Document Type and Number:
WIPO Patent Application WO/2011/099816
Kind Code:
A2
Abstract:
The present invention relates to a high-performance shear friction damper which is provided in built structures and attenuates vibrations which act on built structures due to external factors such as earthquakes and strong winds. The high-performance shear friction damper according to the present invention comprises: first and second supporting bodies supported on a built structure or damping rod; two gusset plates which are secured to the second supporting body and extend so as to cover both side surfaces of the first supporting body; friction plates fitted between the first supporting body and the gusset plates; a tension bolt passing through the first supporting body and the friction plates and also the gusset plates; and a fastening piece comprising a nut that fastens to the end of the tension bolt; wherein the first supporting body is provided with an elongated hole extending horizontally and the tension bolt extends through the elongated hole, thereby allowing the first supporting body to move horizontally in a sliding fashion relative to the friction plate. The high-performance shear friction damper according to the present invention is advantageous in that it is easy to install, and preservation and maintenance are easy since it is easy to separate out and replace just the friction plates when the friction plates have reduced in thickness.
