Abstract

The invention provides a staged yield damper, comprising: upper and lower connecting plates (1), a first energy dissipation steel plate (2), a second energy dissipation steel plate (3), the first energy dissipation steel plate (2) and The second energy-dissipating steel plates (3) are arranged between the upper and lower connecting plates (1), wherein the first energy-dissipating steel plates (2) and the second energy-dissipating steel plates (3) are alternately arranged. In the present invention, by installing alternately arranged first energy-dissipating steel plates and second energy-dissipating steel plates between the upper and lower connecting plates, the stages of different yield degrees formed by the first energy-dissipating steel plates and the second energy-dissipating steel plates damper. The staged yield damper in the invention has simple mechanical properties, convenient installation, stable energy consumption, and can meet the energy consumption requirements of wind vibration, small earthquake and large earthquake at the same time.

Description

technical field [0001] The invention relates to the technical field of civil engineering shock absorption, in particular to a staged yield damper. Background technique [0002] The traditional anti-seismic design of civil engineering structures uses the elastic-plastic deformation of structural components to consume seismic energy and achieve the purpose of mitigating earthquake effects. However, excessive deformation will lead to damage to structural components or even collapse of the structure, causing casualties and loss of life and property. sexual consequences. In order to make the building structure have a strong ability to resist damage from external forces such as earthquakes and wind loads, it is often necessary to add metal energy-dissipating components to the building structure. [0003] At present, the existing metal dampers include mild steel dampers, X-shaped steel plate dampers, rigid-lead combined energy dissipators, etc., but most of these metal dampers can...
