Phased yield type mild steel damper

Abstract

The invention belongs to the field of civil engineering shock prevention and shock absorption and relates to a phased yield type mild steel damper. The upper end and the lower end of an arc-shaped mild steel energy-consuming steel piece on the inner layer of the damper are connected with an internal steel piece upper connection plate and an internal steel piece lower connection plate respectively. The upper end and the lower end of an outer-layer arc-shaped mild steel energy-consuming steel piece are connected with an external steel piece upper connection plate and an external steel piece lower connection plate respectively. The inner-layer arc-shaped mild steel energy-consuming steel piece, the internal steel piece upper connection plate and the internal steel piece lower connection plate are connected into a whole and arranged in a cavity formed by the outer-layer arc-shaped mild steel energy-consuming steel piece, the external steel piece upper connection plate and the external steel piece lower connection plate; springs used for force transferring are arranged between the upper portion of the internal steel piece upper connection plate and the lower portion of the external steel piece upper connection plate and between the upper portion of the external steel piece lower connection plate and the lower portion of the internal steel piece lower connection plate; By the design of inner-layer damping and outer-layer damping and the use of the springs for force transferring, phased energy dissipation and shock absorption of the damper is achieved, and the defect that a traditional damper is single in shock absorption level is overcome.

Description

[0001] 【Technical field】 [0002] 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. [0003] 【Background technique】 [0004] 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 en...
