Coupling structure of single shear wall column and reinforcing method of single shear wall column

Abstract

The invention discloses a coupling structure of a single shear wall column and a reinforcing method of the single shear wall column. The coupling structure comprises the single shear wall column. Thecoupling structure is characterized in that reinforcing units are arranged on two side surfaces of the single shear wall column, wherein each reinforcing unit comprises a steel column which is arranged vertically and at least two coupling beams which are arranged horizontally; one ends of the coupling beams are fixedly connected to the single shear wall column while the other ends of the couplingbeams are fixedly connected to the steel column; all the coupling beams are uniformly distributed vertically, and the single shear wall column, the steel column and all the coupling beams are locatedon a same axle wire. The structure and the reinforcing method are used for reinforcing the single shear wall column to improve the quakeproof ability of the single shear wall column, so that later construction and maintenance are facilitated.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a coupling structure of a single-piece shear wall limb and a reinforcement method for a single-piece shear wall limb. Background technique [0002] Reinforced concrete combined shear wall is one of the main anti-seismic structural forms widely used in high-rise buildings in medium and high intensity areas in my country. The combined shear wall is composed of two adjacent shear wall limbs and the connection beam between the two shear wall limbs. Its resistance mechanism to the overturning moment caused by the horizontal earthquake action includes The tension-compression coupling formed by the adjacent shear wall pier and the bending moment of each shear wall pier itself. In the plastic deformation stage, the combined shear wall disperses the energy consumption to the full height of the structure through the connecting beams. Obviously, due to the coupling...

Problems solved by technology

[0004] However, combined shear wall is a commonly used structural system in buildings at present. Although it is widely used, it has certain limitations: 1. The connecting beam span of combined shear wall depends on non-structural factors such as buildings and equipment. The span-to-height ratio of the beam is generally small; 2. The aseismic design of the connecting beam is relatively complicated no matter what form is adopted, and the construction method of the connecting part with the wall is cumbersome; 3. Since the connecting beam is located in the adjacent Between adjacent wall piers, the span is relatively short, and the coupling beam can only transmit the shear force to the edge area of ​​the wall piers directly connected with it, the actual length of the tension-compression moment arm between adjacent wall piers is limited, resulting in The actual coupling ratio that can be obtained is relatively small; 4. During the earthquake, the vertical tension-compression and other gravity loads caused by the coupling effect on the wall pier make the axial force of the wall pier more complicated; 5. The combined shear wall The structural form is only applicable to the situation where there are two or more adjacent shear wall limbs, and generally exists in the case where the shear wall of the core tube of a high-rise building requires a large opening

Compared with the combined shear wall, the single-piece shear wall has the advantages of less difficulty in construction and simple structural design, but at the same time has the disadvantages of weak earthquake resistance and irreparability in the later stage

[0005] In summary, the combined shear wall has the advantage of stronger seismic resistance than the single shear wall, but the design and construction are more complicated

Compared with combined shear walls, the design and construction of single-piece shear walls are relatively simple, but they do not have the strong seismic performance of combined shear walls.
