Friction Damper Type Earthquake-proof Steel Frame and Earthquake-proof Method using thereof

摘要

The present invention relates to an earthquake-resistant steel frame frame installed in an opening such as a window of a steel-frame concrete structure, comprising: an upper frame portion 110 arranged in a horizontal direction; A lower frame part 120 spaced apart from the upper frame part 110 and arranged in parallel with the lower part of the upper frame part 110; A pair of vertical frame parts 130 connecting both ends of the upper frame part 110 and the lower frame part 120, respectively; And one side of the lower frame part 120 is coupled to a lower part of the vertical frame part 130 and the other side of the lower frame part 120 is connected to the lower frame part 120. [ And a friction damping unit 200 coupled to an end of the friction plate 200 and damping an external force due to frictional force when a displacement occurs due to an external force.
