Self-resetting outrigger damping system after earthquake in super high-rise buildings

Abstract

The invention discloses a semi-girder damping system capable of realizing self-restoration after an earthquake in a super high-rise building. The semi-girder damping system capable of realizing the self-restoration after the earthquake in the super high-rise building comprises oil dampers, hydraulic devices, soft steel dampers and semi-girder trusses, wherein each oil damper is arranged on an outer frame column of the super high-rise building; the hydraulic devices are connected with the oil dampers; the inner end of each semi-girder truss is suitable for being connected with the core barrel of the super high-rise building; the outer ends of the semi-girder trusses are connected with the oil dampers and are connected with the outer frame column of the super high-rise building through the soft steel dampers. According to the semi-girder damping system disclosed by the embodiment of the invention, the self restoration of the super high-rise building can be quickly realized, seismic loss can be reduced, post-earthquake recovery speed is quickened, and the semi-girder damping system has the advantages that the earthquake resistance is good, the structure has a small possibility of being damaged, and structural self restoration is quickly realized.

Description

technical field [0001] The invention relates to the field of civil structural engineering, in particular to an outrigger damping system for realizing self-resetting after an earthquake in a super high-rise building. Background technique [0002] The super high-rise building in the related art adopts the combination form of the middle core tube and the peripheral frame, and coordinates the stress and deformation between the core tube and the frame by setting up outrigger trusses in combination with the refuge floor and the equipment floor. The setting of the outrigger truss can effectively improve the integrity of the structure, reduce the horizontal lateral movement of the structure under the action of the earthquake, and have a certain energy dissipation capacity. Although the structure can prevent the building from collapsing when it is subjected to fortification earthquakes or rare earthquakes, it cannot avoid damage to the outrigger truss itself, shear walls, frame colum...

AI Technical Summary

Problems solved by technology

Although the structure can prevent the building from collapsing when it is subjected to fortification earthquakes or rare earthquakes, it cannot avoid damage to the outrigger truss itself, shear walls, frame columns and other key components under the action of the earthquake load, nor can it guarantee that the building will not be damaged after the earthquake. Restoring its residual deformation, and because key components such as outrigger trusses, shear walls, and frame columns are difficult to reinforce and repair due to their particular location and severity of damage, the entire structure can only be demolished and rebuilt, resulting in huge waste
