Description
Technical Field
The application relates to the technical field of shock absorption, in particular to a multistage yield energy-consumption continuous beam damper.
Background
At present, with popularization and application of energy dissipation and shock absorption technologies and continuous emergence of high-rise and super high-rise building structures, a beam-connected damper is widely applied as one of displacement-related energy dissipaters.
In the prior art, the beam-connected dampers are roughly divided into two types: 1. a shear type metal damper with a single energy-consumption yielding mechanism. The damper uses the metal material to enter a plastic state and then shear yield energy is consumed, so that an additional damping ratio can be provided for the structure under a small displacement, and the earthquake response of the structure is reduced. However, due to the limitation requirements of ductility and fatigue resistance of the metal material, the problem that the damper is damaged due to early yielding of the metal material under heavy shock can occur, and meanwhile, the rigidity of the damper is seriously degraded after yielding, so that the integral rigidity of the structure is greatly reduced. 2. A multi-stage energy-consumption yield mechanism damper. Dampers of this type are broadly divided into two types: a. the shearing yield and the bending yield of the metal material are combined to realize multi-order energy consumption, for example, the utility model patent ZL 202223424536.5 is a double-order yield shearing type continuous beam damper and the like. The damper has the characteristics of multi-stage energy consumption and higher rigidity after yielding, but the energy consumption still utilizes the plastic hysteresis energy consumption of the metal material, and has the defect of a single energy consumption yielding shear type metal damper; b. the utility model discloses a shear damper with a friction pair, which is characterized in that a composite energy consumption mechanism is utilized to realize multi-order energy consumption, for example, the utility model patent ZL 201920321534.2 discloses a shear damper with a friction pair, and the like, the shear damper is connected with the friction damper in series, and two mechanisms of friction energy consumption and metal material plastic hysteresis energy consumption are combined. When one of the yielding mechanisms fails, the damper will fail with lower reliability. "
Therefore, how to provide a high-reliability joint beam damper is a problem to be solved.

The application provides a multistage yield energy-consumption beam-connection damper 1, which comprises two connecting end plates 11, a first-stage energy-consumption mechanism 12 and a second-stage energy-consumption mechanism 13, wherein the two connecting end plates 11 are oppositely arranged, and one sides, far away from each other, of the two connecting end plates 11 are used for respectively connecting building structures, so that the multistage yield energy-consumption beam-connection damper 1 is connected with the building structures. A first-order energy dissipation mechanism 12 and a second-order energy dissipation mechanism 13 are arranged between the two connecting end plates 11 which are oppositely arranged, and the second-order energy dissipation mechanism 13 and the two connecting end plates 11 are enclosed to form a box structure with an accommodating space, so that larger rigidity can be provided, the wall can be effectively restrained, and the rigidity of the whole structure is ensured. The first-order energy dissipation structure is disposed in the accommodating space of the box structure, and includes a first friction plate 121, a first friction plate 122 and a connecting member 123, where the first friction plate 121 and the first friction plate 122 are stacked, so that friction can be generated between the first friction plate 121 and the first friction plate 122 when relative movement is generated between the first friction plate 121 and the first friction plate 122. And the first friction plate 121 is connected with the connection end plate 11, so that the first-order energy dissipation structure is connected with the connection end plate 11, and the first friction plate 121 and the first friction plate 122 are also connected with the second-order energy dissipation structure through the connecting piece 123, so that the first-order energy dissipation mechanism 12 is connected with the second-order energy dissipation mechanism 13.
