Multi-stage energy dissipating device for building structure joint

Abstract

The invention provides a multi-stage energy dissipating device for a building structure joint and belongs to the field of building structure vibration control. The multi-stage energy dissipating device comprises a first-stage energy dissipating rib, a nail penetrating hole, a second-stage energy dissipating oval hole, a second-stage energy dissipating rib, a sliding extrusion end, a fixed end, a middle inner track plate, a connecting end and a middle inner hook plate. A first connecting plate is provided with a plurality of first installing holes. A second connecting plate is provided with a plurality of second installing holes. A right-angle joint shock absorbing inner combination system, a right-angle joint shock absorbing middle inner combination system, a right-angle joint shock absorbing middle outer combination system, a right-angle joint shock absorbing outer combination system and a shock absorbing medium interlayer are arranged between the first connecting plate and the secondconnecting plate. The multi-stage energy dissipating device has the beneficial effects that it is ensured that a joint has sufficient rigidity, the characteristic that shock absorbing and energy dissipating abilities of a traditional building structure right-angle joint are poor is changed, the characteristics of high damping ability, good anti-fatigue performance, low maintenance expense and high shock absorbing ability are achieved, the shock absorbing performance is improved, the building earthquake response can be controlled effectively, and the manufacturing cost is low.

Description

technical field [0001] The invention belongs to the field of building structure vibration control, in particular to a multi-stage energy dissipation device for building structure nodes. 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 r...

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
