U-bar isolation anti-buckling energy dissipation support

Abstract

The invention discloses a U-bar isolation anti-buckling energy dissipation support. The U-bar isolation anti-buckling energy dissipation support comprises a restrain steel pipe, energy dissipation I-shaped bars and an isolation U-bar, wherein both ends of the restrain steel pipe are provided with the energy dissipation I-shaped bars; one end of each energy dissipation I-shaped bar is arranged in the restrain steel pipe; side isolation U-bars are arranged on both sides of the web of each energy dissipation I-shaped bar; the outer side of the flange of each energy dissipation I-shaped bar is provided with an external isolation U-bar; the other end of each energy dissipation I-shaped bar is positioned out of the restrain steel pipe; both sides of the web of each energy dissipation I-shaped bar are fixedly connected with a reinforced steel plate; both ends of the restrain steel pipe are provided with end plates; and filling restrain concrete is poured between the inner side of the end plate and the restrain steel pipe. By adopting an effective isolation way, the restrain concrete is prevented from being damaged, and the energy dissipation capacity is remarkably improved. The U-bar isolation anti-buckling energy dissipation support has the advantages of strong in energy dissipation capacity, simple in processing and convenient in installation, and has favorable earthquake resistance, ductility and hysteretic energy dissipation capacity, and the earthquake response of building structures is reduced to the maximum extent.

Description

technical field [0001] The invention relates to an energy-dissipating support of a building structure, in particular to a channel-steel isolated anti-buckling energy-dissipating support for building structure vibration control. belongs to the field of structural engineering. 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 caus...

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.
