Three-dimensional combined energy dissipation device

Abstract

The invention belongs to the field of building structure vibration control and provides a three-dimensional combined energy dissipation device. The device is formed by enclosure of vertical tension compression energy dissipation steel plate, a horizontal longitudinal shear energy dissipation grating steel plate and horizontal transverse shear energy dissipation grating steel plates. Connection plates are arranged at upper and lower ends outside the device respectively, a cavity of the device is internally provided with an energy dissipation filler material, and large-curved-surface energy dissipation steel plates and round mild steel energy dissipation inner barrels are arranged in the device. Horizontal transverse shear energy dissipation is performed under reciprocating horizontal transverse shear action; horizontal longitudinal shear energy dissipation is performed under reciprocating horizontal longitudinal shear action; under vertical tension compression action, the round mild steel energy dissipation inner barrels and the large-curved-surface energy dissipation steel plates deform for energy dissipation while the energy dissipation filler material is extruded for energy dissipation. Therefore, a quake insulation function is provided for the structure in three-dimensional directions while corresponding stresses and damping are provided, great quake resistance, ductility and hysteretic energy dissipation performances are achieved, and the device is applied to buildings with a three-dimensional quake insulation function.

Description

technical field [0001] The invention belongs to the field of vibration control of building structures, in particular to a three-dimensional combined energy consumption device. Background technique [0002] The massive destruction and collapse of buildings in earthquakes is the direct cause of earthquake disasters. When an earthquake occurs, ground vibrations cause the seismic response of the structure. For a building structure whose foundation is fixed to the ground, its response is amplified layer by layer along the height from bottom to top. Due to the excessive seismic response (acceleration, velocity or displacement) of a certain part of the structure, the main load-bearing structure is seriously damaged or even collapsed; even if the main structure is not damaged, the destruction of building finishes, decoration or other non-structural accessories will also cause Serious loss; damage to indoor expensive instruments and equipment will lead to serious loss or secondary ...
