Abstract

The invention discloses a staged energy-consuming metal damper. The staged energy-consuming metal damper comprises a first connecting plate and a second connecting plate which are arranged in parallel and opposite to each other, wherein at least one first energy-consuming straight steel plate and two second energy-consuming bent steel plates are further arranged between the first connecting plate and the second connecting plate, and the upper end and the lower end of the first energy-consuming straight steel plate are connected with the first connecting plate and the second connecting plate separately and vertically; the two second energy-consuming bent steel plates are symmetrically arranged at the left and right sides of the first energy-consuming straight steel plate in the length direction of the first energy-consuming straight steel plate, and the curved mouth of each second energy-consuming bent steel plate backs on to the first energy-consuming straight steel plate; the upper end and the lower end of each second energy-consuming bent steel plate are connected with the first connecting plate and the second connecting plate separately. According to the staged energy-consuming metal damper, a mode of combination of the shearing energy-consuming straight plate and the shearing U-shaped energy-consuming plate is adopted to form the staged yielding metal damper, and the staged energy-consuming metal damper has good staged yielding capability under small-scale and large-scale vibration; moreover, the staged energy-consuming metal damper has the advantages of being simple in structure, low in cost, convenient for part repairing and replacing and good in economic benefit.

Description

technical field [0001] The invention relates to the technical field of damper design, in particular to a stepped energy-consuming metal damper. Background technique [0002] Metal dampers are the most common passive energy dissipation components in structural engineering. The metal damper uses the good plastic deformation ability of metal materials, and through reasonable design of its structural form and mechanical parameters, it can first yield and consume energy when the engineering structure is subjected to external effects (such as wind loads, earthquakes), thereby ensuring the safety of the main structure . [0003] Metal dampers have the following problems in terms of design and performance: [0004] 1. The existing metal dampers usually have a large bearing capacity and a large size, which causes a lot of inconvenience in the process of production, transportation and installation, and the manufacturing process of the entire metal damper is relatively complicated. ...
