Abstract

The invention discloses a self-resetting lead shear damper. The self-resetting lead shear damper comprises a steel plate composite member, a plurality of first piston members, a box-shaped member, a bottom plate, a fastener, an elastic member and a plurality of second piston members; and the steel plate composite member comprises a flange plate and a web; the first piston members and the second piston members are alternately staggered and fixedly connected in an inserting manner; and a plurality of filling holes are formed in the first piston members and the second piston members, and lead cores are arranged in the filling holes. The self-resetting lead shear damper is clear in force mechanism, simple in structure and low in cost, and has the advantages of self-resetting function, good energy consumption performance, no need to be replaced after strong earthquake.

Description

technical field [0001] The invention relates to the technical field of energy dissipation and shock absorption, in particular to a self-resetting lead shear damper. Background technique [0002] Earthquakes are characterized by strong suddenness and great destructiveness. Earthquake disasters are often instantaneous and sudden natural disasters with a short duration of action, but they can cause great damage to human life and property. However, earthquake defense is very difficult, and earthquake prediction is a worldwide problem. Therefore, we need to think about how to resist earthquakes from the perspective of the building structure itself. [0003] At present, a variety of dampers have been developed, but the existing dampers have poor energy dissipation effect in earthquakes and do not have the function of self-resetting. However, lead has high flexibility and ductility, and can absorb a large amount of heat during deformation. When lead is deformed at room temperature...
