Combination constraint anti-buckling energy dissipation support

Abstract

The invention relates to a combination constraint anti-buckling energy dissipation support. The combination constraint anti-buckling energy dissipation support comprises an outer constraint steel tube, energy dissipation I-shaped steel, a reinforcing steel plate, anti-buckling thin-walled isolation channel steel, an anti-buckling thin-walled isolation and constraint square steel tube, constraint concrete and end plates, wherein two blocks of the anti-buckling thin-walled isolation channel steel are arranged in the anti-buckling thin-walled isolation and constraint square steel tube for forming an I-shaped area and two square areas; the energy dissipation I-shaped steel is arranged in the I-shaped area, and the constraint concrete is arranged in the other two square areas; and the constraint concrete is arranged between the outer constraint steel tube and the anti-buckling thin-walled isolation and constraint square steel tube. The combination constraint anti-buckling energy dissipation support disclosed by the invention has the effects and the advantages that an effective isolation way is adopted, the constraint concrete can be prevented from being damaged, and the energy dissipation capability can be significantly upgraded. The combination constraint anti-buckling energy dissipation support has the advantages of strong energy dissipation capability, simplicity in processing, convenience in mounting and the like, and can enable the structure to have good anti-seismic performance, ductility and hysteresis energy dissipation capability.

Description

technical field [0001] The invention relates to an energy-dissipating support of a building structure, in particular to a combined constraint anti-buckling energy-dissipating support for building structure vibration control. 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...

Problems solved by technology

However, some restrained concrete with anti-buckling energy-dissipating braces is easily crushed and loses its restraint and anti-buckling effects, resulting in a significant reduction in its energy dissipation capacity.
