Problems solved by technology

[0002] At present, the known super high-rise structural system is a frame-core tube structure, and the material is reinforced concrete or a mixture of steel and reinforced concrete and composite members. The method is to increase the structural rigidity by increasing the amount of structural materials without considering the effect of vibration damping equipment, resulting in a waste of structural materials and social resources; the vertical members of the known structure that transmit vertical loads are continuous up and down, without considering the segmental transmission load, resulting in large column sections of all outer frames, affecting the flexibility of architectural layout and the openness of spatial vision
The known structural vibration damping equipment system consists of vibration damping equipment with a single principle, which cannot be effectively combined with the water tank and sightseeing space of the building, and the number of layouts is large, and the layout position is not flexible
The vibration reduction target setting of the vibration reduction equipment system is single, that is, it cannot control the wind vibration comfort, reduce the earthquake effect or reduce the wind load at the same time

Abstract

The invention relates to an ultrahigh and huge steel structure vibration attenuation integrated system. The ultrahigh and huge steel structure vibration attenuation integrated system is applied to a super high-rise building and comprises ultrahigh and huge steel structure units and vibration attenuation device units arranged on the ultrahigh and huge steel structure units, wherein each ultrahigh and huge steel structure unit consists of a main structure sub-unit and a secondary structure sub-unit arranged on the main structure sub-unit, the main structure sub-unit comprises a huge steel frame and a steel core cylinder arranged in the huge steel frame, the huge steel frame consists of multiple huge columns and annular belt trusses arranged on the huge columns, and each vibration attenuation device unit comprises a viscous damping mechanism and / or tuning vibration attenuation mechanism. Compared with the prior art, the ultrahigh and huge steel structure vibration attenuation integrated system has good structural economy and air vibration comfort level, is high in structural efficiency, strong in structural wind resistance and anti-seismic property, low in structural steel consumption, flexible in building arrangement, high in construction speed, high in in vibration attenuation efficiency and the like.

Description

technical field [0001] The invention belongs to the technical field of structural engineering, and in particular relates to an integrated vibration reduction system for super-high giant steel structures used in super-high-rise buildings. Background technique [0002] At present, the known super high-rise structural system is a frame-core tube structure, and the material is reinforced concrete or a mixture of steel and reinforced concrete and composite members. The method is to increase the structural rigidity by increasing the amount of structural materials without considering the effect of vibration damping equipment, resulting in a waste of structural materials and social resources; the vertical members of the known structure that transmit vertical loads are continuous up and down, without considering the segmental transmission Due to the load, the column sections of all the outer frames are larger, which affects the flexibility of architectural layout and the openness of ...
