Energy dissipation brace for composite steel plate

Abstract

The invention belongs to the field of vibration control of building structures, and particularly relates to an energy dissipation brace for a composite steel plate. The energy dissipation brace comprises mounting plates, screw holes, arc-shaped energy dissipation steel plates, aluminum foam energy dissipation materials, reinforcing fixing plates, energy dissipation steel plates, locking nuts, coordination connecting reinforcing bars, internally-formed oval holes, main energy dissipation steel plates, energy dissipation ribs, steel hoops and end energy dissipation steel plates. The structure ofthe energy dissipation brace for the composite steel plate is formed by surrounding of the reinforcing fixing plates, the energy dissipation steel plates and the end energy dissipation steel plates;the energy dissipation ribs are arranged between the adjacent oval holes in the energy dissipation steel plates; the mounting plates are arranged at the two ends of the energy dissipation brace for the composite steel plate and connected with the reinforcing fixing plates; and the multiple screw holes are formed in the mounting plates at equal intervals. According to the energy dissipation brace for the composite steel plate, the plastic distribution of the structure is reasonable; the arranged arc-shaped energy dissipation steel plates, the energy dissipation steel plates and the main energydissipation steel plates are mutually coordinated and extruded to dissipate energy; and when the energy dissipation brace is used under the normal state, the overall rigidity of the building structurecan be improved, and during an earthquake, the energy dissipation brace can have good seismic performance, ductility and the hysteresis energy dissipation capacity.

Description

technical field [0001] The invention belongs to the field of vibration control of building structures, in particular to a combined steel plate energy dissipation support. Background technique [0002] Earthquake disasters are sudden and devastating, which seriously threaten the safety of human life and property. Nearly a thousand destructive earthquakes occur every year in the world, and a major earthquake can cause hundreds of billions of dollars in economic losses, resulting in hundreds of thousands of deaths or serious injuries. 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 ...

Problems solved by technology

The restrained concrete of the anti-buckling energy-dissipating components currently researched and developed is easily crushed and loses the restraint and anti-buckling functions, resulting in a significant reduction in its energy dissipation capacity
