Seismic energy dissipation hollow floor structure system

Abstract

The invention relates to a seismic energy dissipation hollow floor structure system for the technical field of engineering seismology and seismic energy dissipation. The structure system comprises hollow floors, column bracings and damping units, wherein the hollow floors are rigidly connected with or hinged to frame columns and the column bracings; the column bracings can be multiple types of structural components; the damping units are arranged at joints of the bracings and the hollow floors. According to the structure system, the hollow floors are cast-in-situ hollow floors, so that the free height of a room is increased, the story height is reduced, the problem of relatively lower lateral rigidity of an ordinary hollow floor system is solved, and relatively higher structural flexibility is achieved; the energy dissipation capability of damping elements under the seismic action can be fully used for dissipating seismic energy, so that damage of an earthquake to a main structure system is effectively reduced; in addition, the horizontal structural rigidity is not required to be improved, and the used structural space is enlarged; seismic energy dissipation units formed by the column bracings and the damping units are arranged unidirectionally and bidirectionally in the hollow floor structure system, so that the seismic requirements of the structure system can be met, meanwhile, the space of a building space can be fully utilized, and functions of the floor hollows and dampers are fully utilized.

Description

technical field [0001] The invention relates to an energy-dissipating and shock-absorbing hollow floor structure system used in the technical field of engineering anti-seismic, energy-dissipating and shock-absorbing technology. Background technique [0002] The cast-in-place hollow floor is a kind of floor with a cavity inside formed by placing the inner formwork according to certain rules and pouring concrete. It is generally composed of solid open and dark flat beams and a hollow floor. The hollow floor is stressed by small I-beams, which can form a slab-column system and a slab-column-shear wall system. The cast-in-place hollow floor system has the advantages of light weight, less material, lower building height, higher headroom, simple flat formwork construction, omission of beam support process, shortened construction period, reduced construction cost, good sound insulation and heat insulation performance, etc. , can be widely used in multi-storey and high-rise industr...

AI Technical Summary

Problems solved by technology

However, due to the greatly reduced section of the hollow floor structural beam, the lateral displacement stiffness of the slab-column structure system will be small, and the seismic performance of the slab-column itself will be insufficient; if measures such as increasing the section of the column, or adding shear walls, etc. Measures to increase the lateral rigidity of the structure will reduce the usable area of ​​the building, or it is not conducive to opening holes and windows, occupying indoor space, and cannot meet the requirements of building use
