Embodiment 1
[0040] For a flue support, its natural structural frequency is 1.5Hz, the interstory height is about 3.5m, the seismic fortification intensity is 7 degrees, and its interstory displacement angle meets the specification requirements of 1 / 400>1 / 559 under the action of small earthquakes. If it is a conventional method, measures such as increasing the cross-sectional area of the structure, adjusting the overall stiffness or adding concrete slabs will be adopted. However, the present invention intends to use a damper energy dissipation device to achieve the purpose of reducing interlayer displacement. Generally, the interstory displacement when the displacement angle of the frame is 1 / 50 under a large earthquake is taken as the maximum positive and negative travel of the damper. Under the action of a small earthquake, the displacement angle of 1 / 400 can be reached. Add the damper for calculation. When the relative displacement of the damper reaches 6mm, the damping force reaches...
