Steel reinforced concrete rectangular column and special-shaped column transfer frame structure

Abstract

The invention discloses a steel reinforced concrete rectangular column and a special-shaped column transfer frame structure. The steel reinforced concrete rectangular column and the special-shaped column transfer frame structure comprises a bottom rectangular column and a concrete beam connected with the bottom rectangular column. An in-beam longitudinal steel bar and a plurality of in-beam hooping steer bars around the in-beam longitudinal steel bar penetrate through the concrete beam. A special-shaped column with the limb height size being the same with the bottom rectangular column is arranged above the bottom rectangular column. The T-shaped or L-shaped or cross-shaped section steel distributing in the longitudinal direction of the special-shaped column penetrates through the special-shaped column. The periphery of the section steel is provided with an in-column longitudinal steel bar distributing in the longitudinal direction of the section steel and a plurality of in-column hooping steer bars around the in-column longitudinal steel bar so as to a special-shaped column steel skeleton. The special-shaped column steel skeleton is consistent with a steel skeleton in the bottom rectangular column. A steel reinforced concrete special-shaped column distributes in the direction of the upper layer of the bottom rectangular column, so that the layer conversion between a bottom floor and a conversion layer is achieved. A SRC rectangular column frame is adopted at the bottom of the conversion structure, and is applied to commercial buildings. An SRC special-shaped column frame isadopted on the upper portion of the conversion structure, and is applied to residential buildings. The SRC structure has the advantages of high load-bearing capacity and good anti-seismic performance.

Description

technical field [0001] The invention relates to a conversion structure in a commercial and residential composite building, in particular to a frame structure including the conversion of SRC rectangular columns to special-shaped columns. Background technique [0002] With the rapid development of economy, commercial and residential compound buildings are increasing day by day. In commercial-residential composite buildings, the bottom or the bottom floors are usually commercial buildings, and the upper part is set up as residential buildings. The commercial functions meet the daily needs of residents, and the residential functions also provide long-term consumers for businesses. The two rely on each other. In order to meet the requirements of building use, commercial and residential complex buildings often adopt conversion structures. At present, reinforced concrete frame-supported shear wall structures are more widely used. However, the investigation of earthquake damage sho...

Problems solved by technology

However, the investigation of earthquake damage shows that the reinforced concrete frame-supported shear wall structure has poor seismic performance, and is prone to serious damage or even collapse under the action of an earthquake. The damage of the bottom frame is particularly serious, mainly because the rigidity of the bottom frame is much smaller than that of the upper part. The shear wall structure leads to the concentration of deformation at the bottom to form a weak layer. At the same time, the upper shear wall and the bottom frame column are discontinuous, resulting in the interruption of the vertical force transmission path

Therefore, reinforced concrete frame-supported shear walls are not suitable for use in earthquake areas, which greatly limits the application of commercial and residential composite buildings
