Mass particle-tuning type round-bottom all-direction quake damper

Abstract

The invention discloses a mass particle-tuning type round-bottom all-direction quake damper and belongs to the technical field of quake resistance and damping of structural engineering. The mass particle-tuning type round-bottom all-direction quake damper comprises a particle damping box, damping particles, limit springs, vertical isolation springs, a viscous-elastic material, a steel-mixed support, a first spherical steel plate, a second spherical steel plate, wheels and retaining plates. The particle damping box and the damping particles above the wheels in the damper are used for horizontal tuning to damp and dissipate energy. All parts above the vertical isolation springs are used as vertical and swing-direction mass tuning to damp and dissipate energy, and the viscous-elastic material, the lead and steel mixed support and the arc-shaped steel plates form a rotating system which can be used as torsion-direction mass tuning to damp and dissipate energy. Accordingly, damping and energy dissipation can be realized by the damper in all directions. The damper has the advantages of multi-dimensional quake damping, simplicity in manufacturing, convenience and flexibility in arrangement and the like. Under the action of earthquake, the damper can realize energy dissipation and damping in various horizontal, vertical and horizontal torsion directions.

Description

technical field [0001] The invention relates to a damper capable of tuning energy dissipation and shock absorption in all directions of the structure (horizontal directions, vertical directions and torsion), and belongs to the technical field of shock resistance and shock absorption of structural engineering. Background technique [0002] With the improvement of people's living standards, people have higher and higher requirements for the earthquake resistance of building structures, and at the same time, people are paying more and more attention to the comfort of living inside. Earthquake is a complex multi-dimensional movement. When an earthquake strikes, the movement of each particle on the ground is also complex and multi-dimensional, and the seismic wave is also complex and diverse in all directions. The multi-dimensional dynamic action of the earthquake leads to the dynamic characteristics of the building structure under the action of the earthquake. Complex, including...
