Friction Damper Type Earthquake-proof Steel Frame and Earthquake-proof Method using thereof
The present invention is to provide an earthquake-proof steel frame. According to the present invention, a friction damping device is installed inside the bottom edge of a rectangular steel frame so that a corner reinforcement effect can be expected in an elastic displacement section. In addition, when an external force exceeding the elastic displacement section is applied due to an earthquake, friction part deformation and determination are guided so that a lateral force concentrated on the corner is attenuated and steel frame buckling attributable to the lateral force can be effectively prevented. The present invention relates to an earthquake-proof steel frame which is installed in an opening such as a window of a steel concrete structure, including an upper frame part (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); and a friction damping unit (200) mounted at each corner formed by the lower frame part (120) and the vertical frame part (130), having one side coupled to the lower part of the vertical frame part (130), having the other side coupled to the end of the lower frame part (120), and damping an external force with a frictional force in the case of displacement attributable to the external force.
