Abstract

The invention provides a superimposed reset energy consumption connection, and belongs to the field of vibration control of building structures. The top layer is provided with a friction energy consumption plate, the middle layer is provided with right angle friction connections and a rotary extrusion energy consumption plate, and the bottom layer is provided with a crescent-shaped energy consumption connection disc for connecting the two right angle friction connections. A lead pin is used for connecting the friction energy consumption plate and the rotary extrusion energy consumption plate.Lead pins are adopted for connecting the right angle friction connections, the friction energy consumption plate and the crescent-shaped energy consumption connection disc. The connection has the advantages of large initial stiffness, no obvious stress concentration, large steel yield area, good energy consumption effect, high steel utilization rate, simple structure and good economy.

Description

technical field [0001] The invention belongs to the field of vibration control of building structures, in particular to a superimposed reset energy-consuming connection. 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 s...
