Abstract

The invention provides a multidirectional shock absorption damper and belongs to the field of building structure vibration control. A main body of the multidirectional shock absorption damper is defined by an end energy-consuming steel plate, a side supporting energy-consuming steel plate and a horizontal shearing energy-consuming grating plate. Foamed aluminum energy-consuming materials are arranged in an inner cavity of a defined structure, and foamed aluminum energy-consuming plates are arranged on the positions, close to the side supporting energy-consuming steel plate and the horizontal shearing energy-consuming grating plate, in the defined structure correspondingly. A circular soft steel energy-consuming inner tube is arranged in the middle in the defined structure, and a pluralityof arc-shaped energy-consuming steel plates are symmetrically arranged on the two sides of the circular soft steel energy-consuming inner tube. The upper ends and the lower ends of the arc-shaped energy-consuming steel plates are fixedly connected with the end energy-consuming steel plate. The multidirectional shock absorption damper has the beneficial effects that the initial rigidity is large, the material yield scattering area is large, recoverable deformation is large, the damping capacity is high, and the good vibration-resistant property, ductility and hysteretic energy-consuming capacity are achieved.

Description

technical field [0001] The invention belongs to the field of vibration control of building structures, in particular to a multi-directional shock absorbing damper. 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. my country is located in the two most active seismic belts in the world, and is one of the countries that suffered the most serious earthquake disasters. The casualties caused by the earthquake rank first in the world, and the economic loss is also very huge. 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 structu...
