Steel lead laminated ring damper

Abstract

The invention discloses a steel and lead laminated annular damper comprising soft steel energy dissipation barrels, lead energy dissipation barrels and steel supports. The soft steel energy dissipation barrels and the lead energy dissipation barrels are alternatively laminated to form an energy dissipation barrel. The energy dissipation portion of the energy dissipation barrel is hooped by four square-cylinder-shaped connecting plates, the four connecting plates are symmetrical pairwise relatively to the center of the energy dissipation barrel and form an 'X' shape, and fixed plates with screw holes are connected with the connecting plates respectively. The steel and lead laminated annular damper is high in stress concentration, large in material yield dispersion area, free of obvious stress concentration, good in coordination of the soft steel energy dissipation barrels and the lead energy dissipation barrels, high in material utilization rate, good in energy dissipation effect, simple to produce and mount and convenient to use, can be used for seismic design of new construction projects and can also be used for consolidation maintenance of existing projects.

Description

technical field [0001] The invention relates to a vibration control device for a building structure, in particular to a steel-lead laminated annular damper for building structure vibration control. Background technique [0002] Structural energy dissipation and vibration reduction technology is to design some non-load-bearing components of the structure (such as supports, shear walls, connectors, etc.) Wait, install the energy dissipation device. When there is a small wind or a small earthquake, these energy-dissipating rods or energy-dissipating devices and the structure itself have sufficient lateral rigidity to meet the requirements of use, so that the structure is in an elastic state; As the deformation increases, the energy-dissipating components or energy-dissipating devices start to work first, resulting in greater damping, consuming a large amount of earthquake or wind vibration energy input into the structure, and converting the kinetic energy or elastic potential ...
