Damper with staging energy consumption function

Abstract

The invention relates to a damper with a staging energy consumption function, and belongs to the technical field of building structural engineering. The damper comprises two energy consumption platesand connecting plates. The two energy consumption plates are arranged in the corner between a frame beam and a frame column and conduct staging energy consumption. The connecting plates are used for connecting the energy consumption plates with the frame beam and the frame column. The distances between the two energy consumption plates and the center of rotation are different. The connecting plates and the energy consumption plates are connected through welded joints. The distance between the energy consumption plate on the inner side and the center of rotation and the distance between the energy consumption plate on the outer side and the center of rotation are different. Along with the increase of the rotational angle, the energy consumption plate on the outer side consumes energy, thenthe energy consumption plate on the inner side consumes energy, and then staging energy consumption is achieved. Compared with an existing damper, the damper with the staging energy consumption function has the advantage of achieving the better energy consumption effect. The damper with the staging energy consumption function is simple in structure, the most of connection is bolted connection, andthe assembling operation can be achieved. After an earthquake happens, seismic reduction and energy dissipation can be conducted, replacement is convenient, and the damper with the staging energy consumption function can be widely applied to the technical field of seismic reduction and energy dissipation of building structures.

Description

technical field [0001] The invention relates to a staged energy dissipation damper, which belongs to the technical field of building structure engineering. Background technique [0002] The production mode of the traditional construction industry can no longer meet the needs of the development of the times. The State Council has put forward requirements for green buildings, and the prefabricated buildings are in line with the connotation of building industrialization and greening. The prefabricated structure has the advantages of being green and convenient. However, the nodes of this structure have defects of low stiffness at the joints. Under the action of earthquakes, damage is easy to occur from the nodes, which reduces the reliability of the entire structure. Therefore, the seismic resistance of the prefabricated structure nodes Design has always been the focus of research. [0003] The traditional anti-seismic design concept allows structural lateral force-resistant co...

The prefabricated structure has the advantages of being green and convenient. However, the nodes of this structure have defects of low stiffness at the joints. Under the action of earthquakes, damage is easy to occur from the nodes, which reduces the reliability of the entire structure. Therefore, the seismic resistance of the prefabricated structure nodes Design has always been the focus of research

[0003] The traditional seismic design concept allows structural lateral force-resistant components to dissipate seismic energy through plastic deformation, but this will lead to damage and residual deformation of structural components. After the earthquake, the repair period of the building is long and the repair cost is considerable.
