METALLIC DAMPER WITH TAPERED STRIP

摘要

The present invention relates to a strip type steel damper which has energy dissipation improved efficiency by evenly distributing load over a strip when horizontal load is generated by earthquake load, the strip type steel damper comprising: an upper fixed plate having the front side fixed on a construction; a lower fixed plate which is arranged with a fixed space from and in parallel with the lower side of the upper fixed plate and which has the front side fixed on the construction; and multiple strips which has an upper end connected to the lateral side of the lower end of the upper fixed plate and a lower end connected to lateral side of the upper end of the lower fixed plate, which have multiple strips formed by being formed at constant intervals along the lateral directions of the upper and lower fixed plates and which have the shapes having the widths of the upper and lower ends wider than that of the middle portion thereof, wherein the strip has the end whose width and height are in the aspect ratio of 1:5-1:8.
