High-rise structure floor slab shock absorption structure releasing multi-direction freedom degrees

Abstract

The invention relates to a high-rise structure floor slab shock absorption structure releasing multi-direction freedom degrees. The floor slab shock absorption structure comprises a body stress frame and a buffering damping mechanism arranged in the body stress frame and applying a tuning function on the body stress frame; the body stress frame comprises a foundation slab, shear walls vertically arranged on the foundation slab and rigid cross beams arranged at the tops of the shear walls, the buffering damping mechanism comprises floor slabs arranged on multiple layers in parallel at equal intervals and elastic buffering units arranged around the floor slabs, and the floor slabs are connected with the shear walls through the elastic buffering units in a sliding mode. Compared with the prior art, the shock absorption structure is simple in structure and compact in layout; as viscous dampers are arranged in the four directions of the body stress frame, and rolling wheels are arranged in the four directions of the floor slab, the multi-direction freedom degrees of the floor slabs can be released, the shock absorption effect is excellent, and the shock absorption structure has excellent application prospects.

Description

technical field [0001] The invention belongs to the technical field of damping devices, and relates to a damping structure for a floor of a high-rise structure, in particular to a damping structure for a floor of a high-rise structure releasing multi-directional degrees of freedom. Background technique [0002] Earthquake is a kind of natural disaster. Earthquake will produce seismic wave, which will cause the building to rise and fall vertically and swing horizontally. When the shear or tensile stress of the building exceeds the ultimate strength of the building, the building will It will break and collapse, causing serious damage. Earthquake disaster is one of the main natural disasters that affect the safety of buildings. [0003] The mega-frame structure is composed of a main structure composed of several large structural units and a substructure composed of other structural units to form a high-rise building structure system with better overall stability and higher eff...

AI Technical Summary

Problems solved by technology

The technical solution disclosed in the above patent can only release degrees of freedom in one direction. Since the earthquake direction position is often superimposed in multiple directions, this shock absorption method has relatively large limitations and must release degrees of freedom in multiple directions.

At the same time, the roller bearing in this patent has no additional structures such as chute between the floor slab and the main structure, which restricts the beating of the floor slab in the vertical direction, and the floor slab is easy to move up and down during the earthquake, which exerts greater stress on the suspension cables , and also caused the people on the floor to feel more violently
