Problems solved by technology

[0003] (1) Increasing the beam height will not be able to achieve a light and thin building effect, and increasing the beam width or number of beams will significantly increase the construction cost;
[0004] (2) The additional structural columns affect the building effect and the traffic demand of the lower part;
[0005] (3) The arched structure requires a large amount of lifting in the middle of the beam, and the section of the vertical web bar of the vierendeel truss requires a large amount, which affects the architectural effect of the facade;
[0006] (4) The vibration reduction effect of TMD is limited, and it may not be possible to meet the vibration reduction requirements by setting TMD alone, and setting TMD will increase the structural load burden to a certain extent

Embodiment 1

[0087] Such as image 3 As shown, the multi-layer vibration suppression structure has an upper floor component 2 , a middle and upper floor component 2 , a middle and lower floor component 2 and a lower floor component 2 . Between the upper floor member 2 and the middle and upper floor member 2, the middle and upper floor member 2 and the middle and lower floor member 2, the middle and lower floor member 2 and the lower floor member 2, the two ends of which are respectively connected by rigid joint columns 31, and the middle spans are respectively A tension member 32 is provided. The tension components 32 are arranged vertically. This embodiment is the simplest implementation form of the present invention, and has the least impact on the facade.

Embodiment 2

[0089] Such as Figure 4 As shown, the multi-layer vibration suppression structure has an upper floor component 2 , a middle and upper floor component 2 , a middle and lower floor component 2 and a lower floor component 2 . Between the upper floor member 2 and the middle and upper floor member 2, the middle and upper floor member 2 and the middle and lower floor member 2, the middle and lower floor member 2 and the lower floor member 2, the two ends of which are respectively connected by rigid columns 31, and the middle part is in each Several tension components 32 are arranged at equal intervals in the layers. The tension components 32 of each layer are arranged vertically, and the tension components 32 of different layers are aligned. Compared with Embodiment 1, this embodiment has a better vibration suppression effect.

Embodiment 3

[0091] Such as Figure 5 As shown, the multi-layer vibration suppression structure has an upper floor component 2 , a middle and upper floor component 2 , a middle and lower floor component 2 and a lower floor component 2 . Between the upper floor member 2 and the middle and upper floor member 2, the middle and upper floor member 2 and the middle and lower floor member 2, the middle and lower floor member 2 and the lower floor member 2, the two ends of which are respectively connected by rigid columns 31, and the middle part is in each A number of tension components 32 are arranged at unequal intervals in the layers. The tension components 32 are arranged vertically, and the tension components 32 of different layers are aligned. Compared with Embodiment 2, this embodiment can meet the requirements of specific visual effects or use functions.

Abstract

The invention belongs to the technical field of building structures, and particularly relates to a multi-layered vibration suppression structure with a tension assembly. Stress and deformation of a plurality of floors are associated by arranging thin tension assemblies between the floor components of the adjacent floors, so that the structure can be widely applied to structure response control of various large-span or long cantilever structures under vibration loads of pedestrians, vehicles, equipment and the like. The structure is simple, transparent in vertical surface effect, high in vibration control efficiency and good in economical efficiency.

Description

technical field [0001] The invention belongs to the technical field of building structures, in particular to a multi-layer vibration suppression structure with tension components. Background technique [0002] Long-span or long-overhang structures are widespread building structures. Due to the small vertical stiffness of the structure, obvious structural vibrations may occur under the excitation of vibration loads such as pedestrians, vehicles, and equipment, which will affect the comfort and even It causes people's psychological panic, so it is necessary to control the structural vibration response. Common control methods include: increasing structural rigidity (such as increasing beam section size, increasing beam width or number of beams), increasing support points (such as adding structural columns to reduce span), changing structural forms (such as lifting the middle of the beam so that it become an arched structure, add columns to form a vierendeel truss structure, et...
