Elastic friction damper using wedge and damping structure using the same

摘要

The elastic friction damper according to the present invention adjusts the inclination angle of the wedge member within an appropriate range and allows the wedge member to be disposed in the throttle direction, thereby cushioning the large horizontal displacement of the long bridge, but also reducing the seismic energy in the event of an earthquake. Can be dissipated. The elastic friction damper according to the present invention has a first inclined surface and a side-supported friction wedge for supporting one side of the second structure in one direction, and a second inclined surface, and a pressurized friction wedge mounted on the side-supported friction wedge And an elastic pressing mechanism coupled to the installation target member to elastically press the pressing friction wedge toward the side supporting friction wedge.
