Description

Technical Field

[0001] The utility model relates to the technical field of composite dampers, in particular to a composite damper which consumes energy in stages. Background Art

[0002] Earthquakes, as one of the natural disasters, can cause serious damage to building structures. Traditional earthquake-resistant design is to resist earthquakes by enhancing the seismic performance of the structure itself, that is, to use the structure itself to store and consume seismic energy to meet the structural seismic fortification standards: small earthquakes will not damage, medium earthquakes can be repaired, and large earthquakes will not collapse. However, this earthquake-resistant method lacks self-regulation ability and is likely to fail to meet safety requirements under uncertain earthquakes. Energy dissipation and shock reduction technology, as a rapidly developing new technology, increases structural damping by setting dampers at appropriate locations of the building structure, thereby reducing the structure's response to wind and earthquakes. Research results in recent years have proven that this technology is effective and practical.

[0003] When existing building structures are subjected to earthquakes, their destructive forces vary in magnitude. Dampers are important energy dissipation devices, but traditional composite dampers can only play an earthquake-resistant role for larger or smaller earthquakes and cannot be used to consume the energy caused by earthquakes in different situations. In order to solve this problem, a composite damper with staged energy dissipation is proposed. Utility Model Content
