Staged Yield Type Mild Steel Damper

Abstract

The invention belongs to the field of anti-seismic and shock-absorbing civil engineering, and relates to a staged yield type mild steel damper. The upper and lower ends of the inner arc-shaped mild steel energy-dissipating steel sheet are respectively connected to the upper connection plate of the inner steel sheet and the lower connection of the inner steel sheet. On the board, the upper and lower ends of the outer arc-shaped mild steel energy-dissipating steel sheet are respectively connected to the upper connecting plate of the outer steel sheet and the lower connecting plate of the outer steel sheet; the inner arc-shaped mild steel energy-dissipating steel sheet and the upper connecting plate of the inner steel sheet It is connected with the lower connecting plate of the inner steel sheet as a whole and set in the cavity surrounded by the outer arc-shaped mild steel energy-dissipating steel sheet, the upper connecting plate of the outer steel sheet and the lower connecting plate of the outer steel sheet; the upper connecting plate of the outer steel sheet There are springs for force transmission between the lower part and the upper part of the upper connecting plate of the inner steel sheet and between the upper part of the lower connecting plate of the outer steel sheet and the lower part of the lower connecting plate of the inner steel sheet; The force transmission realizes the staged energy dissipation and shock absorption goal of the damper, and overcomes the disadvantage of the single shock absorption level of the traditional damper.

Description

【Technical field】 [0001] The invention belongs to the field of anti-seismic and shock-absorbing civil engineering, and in particular relates to a metal energy-dissipating damper in a structural shock-absorbing control system, in particular to a staged yield type mild steel damper that can be used for corners and column feet of shear walls. 【Background technique】 [0002] Metal energy dissipation dampers use different forms of plastic hysteretic deformation of metals to dissipate energy. Because metal has good hysteresis characteristics after entering the plastic state, and absorbs a large amount of energy during the elastic-plastic hysteretic deformation process, it is used to manufacture energy-dissipating shock absorbers of different types and structures. From the force form, it can be divided into axial yield type, shear yield type, bending yield type and torsional yield type damper. Representative products that have been formed: X-shaped and triangular energy dissipator...
