Problems solved by technology

When the structure is subjected to horizontal forces, the coupling beams in the cylinder are subjected to a large force. In order to ensure the safety of the structure and prevent shear damage, the calculation of the reinforcement value of the coupling beams often exceeds the limit, which brings difficulties to the section design.
Moreover, in a frame-tube structure with a relatively complex plane (such as the eccentric setting of the core tube), the value of the cross-section of a certain connecting beam sometimes has a great impact on the dynamic characteristics of the entire structure, making multiple earthquakes such as period and displacement ratio Indicators Difficult to Meet Specification Requirements
Therefore, the design of coupling beams in frame-core tube structures with complex planes is often more difficult than the design of coupling beams in ordinary shear wall structures.
At the same time, as the most important lateral force-resisting component, the wall of the core tube often weakens the torsional performance of the structure due to the need to leave holes for door openings, fire hydrants and pipelines
[0005] (2) Poor economy
The anti-overturning moment arm of the core tube with a large height-to-width ratio (compared with the outer frame) is small. The only way to increase the anti-overturning moment of the core tube is to increase the self-weight and reduce openings, which will inevitably increase the amount of steel used. , increasing the construction cost
[0006] (3) The utility rate is not good, and the plane function layout is limited
In the traditional frame-core tube structure, the design of the core tube gives priority to the lateral force resistance of the structure, followed by the vertical traffic and equipment layout, so that there will be deviations in the core tube structure and functional design, such as the core tube There is no problem with the structural design of the tube, but the plane layout design in the core tube has ample or insufficient space. Since the structural design of the core tube involves the design of the entire building structure, it is very difficult and cumbersome to adjust
In order to avoid insufficient space for the core tube and increase the anti-overturning moment, the cross-sectional area of ​​the core tube is often designed to be relatively large, thereby reducing the practical rate of the building structure

Embodiment 1

[0044] like Figures 1 to 3 As shown, the super high-rise building structure without an inner tube in this embodiment includes: an outer frame tube structure formed by combining the first SRC columns and SRC window skirt beams 22, and an inner frame structure formed by combining vertical columns 11 and connecting beams 12 , and several floors for connecting the outer frame tube structure and the inner frame structure. The inner frame structure is set eccentrically, and its geometric center deviates from the geometric center of the outer frame tube, as shown in the attached image 3 The geometric center of the inner frame structure shown is located in the northwest area of ​​the outer frame tube structure. If the traditional frame-core tube structure is adopted, the design of the inner core tube and the design of the connecting beam between the outer frame and the inner core tube will be quite complicated and difficult to design. However, after using the structure of the oute...

[0063] like Figure 7 As shown, the super high-rise building structure without an inner tube in this embodiment includes: an outer frame tube structure formed by combining the first SRC columns 61 and SRC window skirt beams 62; an inner tube structure formed by combining the vertical columns 51 and connecting beams 52; frame structure, and several floors for connecting the outer frame tube structure and the inner frame structure.

[0064] like Figure 7 As shown, the cross-section of the outer frame tube of this embodiment is rectangular, and no columns are set at its four corners. Each side of the outer frame tube structure has nine first SRC columns 61 with a column distance of 4.5m. The horizontal section of the inner frame structure is rectangular, the vertical columns 51 at the four corners are reinforced SRC columns, and the rest are ordinary SRC columns. The vertical columns 51 of the inner frame structure are arranged symmetrically. For either side, there are two ve...

Abstract

The invention relates to a building structure, in particular to a super high-rise building structure without an inner tube. The super high-rise building structure comprises a plurality of SRC (steel reinforced concrete) columns, a plurality of SRC window skirt beams, a plurality of vertical columns, a plurality of connection beams and a plurality of floors, wherein the SRC columns and the SRC window skirt beams are arranged at the periphery of the building structure and are used for forming an outer framed-tube structure; the vertical columns and the connection beams are arranged inside the building structure and are used for forming an inner frame structure; and the floors are used for connecting the outer framed-tube structure with the inner frame structure. The connection beams of the building structure are simpler in structural design, and the building structure can adapt to a more complicated and irregular structure, and is more material-saving and economic.

Description

technical field [0001] The invention relates to a building structure, in particular to a super high-rise building structure without an inner cylinder. Background technique [0002] At present, the frame-core tube structure is widely used in super high-rise buildings in my country. The structure is composed of the core tube and the peripheral sparse column frame. The column spacing is generally 8m to 12m. The columns and surrounding beams form an outer frame, and the outer frame passes through the beams and floors. It is integrated with the central core tube. The functions in the core tube are mainly elevator rooms, stairwells, pipe wells and fire protection antechambers, and public toilets can also be placed in the core tube if necessary. [0003] Although the frame-core tube structure has many advantages and is widely used, it also has some disadvantages, such as: [0004] (1) The design of the coupling beam is difficult. The coupling beam in the frame-core tube structure...
