Problems solved by technology

[0005] The technical problem to be solved by the present invention is that the buckling-constrained support has a large initial elastic stiffness, and cannot play an energy-dissipating role when the structural displacement is small, so that the building structure cannot meet our required interstory displacement in the case of a small earthquake corner request

Abstract

The embodiment of the present invention discloses a first-order frictional buckling-constrained support, which includes a friction damper and a buckling-constrained support. The friction damper includes an inner sleeve, an outer sleeve, and a friction material. One end is connected, the friction material is arranged on the inner side of the outer sleeve, and the outer sleeve is sleeved on the outer side of the inner sleeve, and the inner sleeve slides toward or away from the buckling restraint support; the buckling restraint support includes a first connecting plate, a consumption An energy core plate, an outer constraint sleeve and a second connection plate, one end of the energy dissipation core plate is connected to the first connection plate, and the other end is connected to the second connection plate, and the outer constraint sleeve is sleeved on the outside of the energy dissipation core plate. The present invention makes use of the frictional damper's characteristics of energy consumption and strong energy dissipation capacity when the displacement occurs to make up for the defect that the buckling restraint support cannot consume energy in the case of small displacement, so that the energy dissipation capacity of the product of the present invention under small earthquakes is greatly improved, and the energy consumption is reduced. The interstory displacement angle under the small earthquake of the structure is reduced, and the structural damage is reduced.

Description

technical field [0001] The invention relates to the technical field of anti-seismic engineering structures, in particular to a first-order frictional buckling restraint support. Background technique [0002] Nearly a thousand destructive earthquakes occur every year in the world, and a major earthquake causes hundreds of thousands of casualties and hundreds of billions of dollars in economic losses. my country is located in the two most active seismic belts in the world, and the casualties caused by earthquakes rank first in the world. The massive destruction and collapse of buildings in earthquakes is the direct cause of earthquake disasters. The traditional anti-seismic method is to dissipate the seismic energy through the plastic deformation of the structure itself. The essence is to use the structure itself and its components as "energy dissipation" elements, which will inevitably cause damage or even collapse of the structure. The deformation and damage of the buildin...
