Description
Technical Field
The invention relates to a frame-core tube structure, namely a high-rise building structure consisting of a core tube and a peripheral thin column frame, in particular to a frame-core tube structure with inner frame columns.
Background
The frame-core barrel structure system consists of a ductile frame and a barrel body. The lateral stiffness of the core tube surrounded by the shear walls is larger than that of the peripheral frame, most of shear force generated under the action of wind load and earthquake is borne, the core tube is a main lateral force resistant component of the structure, and the core tube is a first defense line of a frame-core tube structure system. The frames arranged around the core barrel mainly bear the vertical load of the structure and share a small part of horizontal shear force. Because the force arm of the frame outer column is larger, the frame outer column can bear larger overturning bending moment, and the peripheral frame after reasonable design is a second defense line of the frame-core tube structure system. In a high-intensity area (eighty degrees and above), static elastoplasticity analysis and elastoplasticity time-course analysis are carried out on the frame core tube structure under the action of a large earthquake, and the analysis result shows that the core tube is seriously damaged, and part of the wall body loses the bearing capacity. The traditional frame-core tube structure consists of a peripheral frame and a core tube, namely, a core tube wall body is connected with a peripheral frame column through a frame beam and a floor slab, and the core tube and the peripheral frame column are not vertically supported.
Chinese patent CN109944335A discloses in 2019, 6, 28, a frame and shear wall core tube combined assembly type structural system, which includes a shear wall core tube and a plurality of frame columns arranged around the shear wall core tube, wherein frame beams are horizontally arranged between the shear wall core tube and adjacent frame columns and between the adjacent frame columns; and a frame secondary beam is vertically arranged between the parallel frame beams, and secondary structure walls are filled below the frame secondary beam and below the frame beam. Although the technical scheme enhances the connection strength of the L-shaped nodes of the core cylinders of the two steel concrete combined pipe shear walls and adopts the cast-in-place and prefabricated combined frame columns, the overall scheme still belongs to the structure of the core cylinders and the peripheral frame columns, and the defect of building collapse cannot be overcome under the action of a high-intensity area (over eight degrees) and a large earthquake.
The known frame-core tube structures thus suffer from the inconveniences and problems described above.
