Embodiment 1

[0025] A quicksand type hybrid energy dissipation shock absorption and damping device includes a damper cavity 1 and a mounting plate 4 . The damper cavity 1 has a hollow cavity, and the damper cavity 1 is filled with a mixture 2 of sand and water (which may be saturated sand).

[0026] see figure 1 , the damper cavity 1 is fixed on the upper surface of the mounting plate 4 . The lower surface of the mounting plate 4 is connected with structural components. In the embodiment, the mounting plate 4 is a flat steel plate with several mounting holes 5 on the plate surface. During installation, the installation plate 4 and the damper cavity 1 connected thereto can be fixed on the components by bolts passing through the installation holes 5 .

[0027] see figure 2 , which shows the internal structure of the damper. That is, several balls 3 and / or pebbles are loaded into the damper cavity 1 . In this embodiment, the volume of the damper cavity 1 shown can be selected according...

Embodiment 2

[0036] The main structure of this embodiment is the same as that of Embodiment 1.

[0037] In Embodiment 1, the damper cavity 1 may be a container with an open upper end and a closed lower end, so as to meet the requirement of holding water. Preferably, in order to avoid adverse effects on personal safety, the damper cavity 1 should have a certain degree of sealing. In this embodiment, a top cover can be added to the damper cavity 1, or a plastic mesh and turf can be added to the upper surface of the mixture 2, which can maintain moisture and beautify the environment, meeting environmental protection requirements.

[0038] Further, the damper chamber 1 is a hollow cube or cylinder surrounded by steel plates, the hollow cube or cylinder has an open upper end and a closed lower end, making it a container with an open upper end. In an embodiment, the upper opening of the container may be sealed by a steel cover plate. Alternatively, the damper cavity 1 is a hollow cube or cylin...

Abstract

The invention discloses a quicksand type energy dissipation shock absorption and damping hybrid device. The device comprises a damper and an installing plate. The damper is provided with a cavity and fixed to the upper surface of the installing plate. The lower surface of the installing plate is connected with a building structural component. A cavity of the damper is filled with a plurality of balls and/or cobblestones and a mixture of sand and water. The device integrates the advantages of a tuned liquid damper, the advantages of a tuned mass damper, the advantages of a viscous damper and the advantages of a particle damper, is good in energy dissipation effect and has high applicability in the constructional engineering anti-seismic and wind resistance fields.

Description

technical field [0001] The invention relates to the technical field of shock absorption and wind resistance of building structure engineering. Background technique [0002] With the development of high-rise buildings in the direction of large aspect ratio and lightweight and high-strength materials, the structural stiffness and damping gradually decrease, and they become more and more sensitive to strong excitations such as wind and earthquakes. Structural vibration control, as an economical and effective method, has been paid more and more attention in recent years, and anti-seismic and energy-dissipating shock-absorbing technologies have also been fully applied and developed in engineering. [0003] From the perspective of control theory, building shock absorption technology mainly includes four methods: active control, passive control, semi-active control and hybrid control. Among them, the damper, which is widely used, is a kind of passive control. Many scholars at home...
