Multi-layer large-space building structure and design method thereof

Abstract

The invention discloses a multi-layer large-space building structure and a design method hereof. The multi-layer large-space building structure is suitable for a multi-layer large-space building withlow absolute span needs, and comprises a composite building structure main body, wherein the building structure main body comprises wall bodies, multiple layers of girderless floors and multiple supporting columns, the wall bodies are concrete laterally-stressed balance wall bodies, and are used for bearing horizontal force of the building structure main body while providing a vertical building space; the multiple layers of girderless floors are positioned between the wall bodies and are connected to the wall bodies, and a reinforcing steel bear for transmitting horizontal load is arranged inthe girderless floor at each layer; each supporting column is a freely distributed type swing column, and is used for bearing vertical force in the vertical direction; and the two ends of each supporting column are separately connected to the girderless floors. The invention further provides the design method for the multi-layer large-space building structure. The multi-layer large-space buildingstructure improves space use efficiency, reduces visual impact on space permeability and solves the horizontal stress problem of the building.

Description

technical field [0001] The invention relates to a building structure and a design method, in particular to a multi-storey large-space building structure and a design method thereof. Background technique [0002] For multi-storey large-space buildings, the prior art generally adopts column-free large-span structures and beam-column frame structures. The use of column-free long-span structures requires a large structural beam height, especially in multi-storey buildings, where the space utilization efficiency is not high; the use of beam-column frame structures is limited by the regular column network, and the choice of spatial models for buildings is limited. Under the requirement of lateral force resistance, the size of the column will also restrict the spatial transparency. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multi-storey large-space building structure and a design method thereof for the above-men...

Problems solved by technology

The use of column-free long-span structures requires a large structural beam height, especially in multi-storey buildings, where the space utilization efficiency is not high; the use of beam-column frame structures is limited by the regular column network, and the choice of spatial models for buildings is limited. Under the requirement of anti-lateral force, the size of the column will also restrict the space transparency effect
