Description

technical field

[0001] The invention belongs to the field of civil engineering, and relates to a lap joint type self-centering friction energy consumption support for reducing earthquake disasters of engineering structures. Background technique

[0002] Earthquakes bring extremely serious disasters to human beings. The traditional seismic design adopts the ductility design method, that is, under the action of an earthquake, through the early yield and failure of some structural components, but the overall function will not be lost, relying on the plastic deformation of the components to dissipate most of the seismic energy, so as to achieve The purpose of ensuring the safety of the main structure.

[0003] Frictional energy-dissipating support is an energy-dissipating member that converts kinetic energy into heat energy through sliding friction to dissipate seismic energy. Due to its strong energy dissipation capacity, good shock absorption effect, and easy replacement aft...
