Problems solved by technology

For the connected damping system, the damping effect depends on the characteristics of the connecting parts on the one hand, and on the other hand, the period ratio of the main structure to the secondary structure and the damping ratio of itself also affect the damping effect, but the current damping structure effect not ideal

Embodiment 1

[0019] A layered sway damping system such as figure 1 , as shown in 2, includes a flexible main structure 2 and a rigid substructure 1. The flexible main structure 2 and the rigid substructure 1 are connected by a connecting part 6 that provides stiffness and damping. At each layer, the rigid substructure 1 and the flexible main structure Connection parts 6 are provided between the structures 2 . The flexible main structure 2 is a steel frame hinged with layered swinging beams and columns, and the rigid secondary structure 1 is a rigid frame or a shear wall rigidly connected to the ground. In this embodiment, the flexible main structure 2 is hinged at both ends of the layered Composed of column 4, continuous beam 5 and floor slab 3, such as image 3 , 4 As shown, the two ends of the hinged column 4 and the continuous beam 5 are hinged by bolts 9, and a backing plate 7 is arranged between them, and a floor panel 3 is arranged between the continuous beams 5, and stiffeners 8 a...

Abstract

The invention relates to a layered swing type damping system which comprises a flexible main structure and a rigid auxiliary structure. The flexible main structure and the rigid auxiliary structure are connected through a connection component which provides rigidity and damping. The flexible main structure is a steel frame formed by hinging layered swing type beam columns. The rigid auxiliary structure is a rigid connection frame or a shear wall in rigid connection with the ground. Compared with the prior art, according to the damping system, a vertical bearing structure is separated from a horizontal lateral force resistance structure, the flexible main structure bears the most ravity of the structure, the rigid auxiliary structure resists the horizontal load, the flexible main structure and the rigid auxiliary structure are connected through the connection component which provides rigidity and damping, the most earthquake input energy is dissipated, and the damping effects of reducing interlayer displacement to a large degree and greatly reducing the floor accelerated speed are achieved.

Description

technical field [0001] The invention belongs to the technical field of shock absorption, and in particular relates to a layered swing type shock absorption system. Background technique [0002] Many building structures designed according to the current seismic codes will be severely damaged due to excessive plastic deformation under a major earthquake, requiring large-scale repairs or even being unusable. Some experts proposed to concentrate energy consumption on certain secondary structural components that are easy to repair or replace after an earthquake, so as to ensure that the primary structure remains elastic under strong earthquakes. Connecting shock-absorbing devices are installed between adjacent buildings, and the shock-absorbing effect is achieved through the interaction between building structures. This type of shock-absorbing method is called connected shock-absorbing. This shock absorption method can also solve the phenomenon of pounding effect caused by out-o...
