Rotatable type self-resetting energy consumption device

Abstract

The invention provides a rotatable type self-resetting energy consumption device, and belongs to the technical field of damping. The rotatable type self-resetting energy consumption device comprises aself-resetting part, an energy consumption part and a connecting part, wherein the self-resetting part comprises a cutting steel plate with carving teeth, an annular spring and a high-strength bolt;the energy consumption part adopts a cutting type damper; the connecting part comprises a connecting plate and a high-strength bolt; the post-earthquake automatic resilience is achieved through the self-resetting part to eliminate residual deformation; the earthquake energy is dissipated through the energy consumption part; the connecting part connects the rotatable type self-resetting energy consumption device with a structural assembly, restrains the concrete of a nodal region, and improves the earthquake resistance capacity of a node. The rotatable type self-resetting energy consumption device can be installed on a beam column node or a pedestal node, the use function of a building is not affected, not only can a self-resetting capacity be provided, but also an energy consumption capacity can be provided, no residual displacement exists after the earthquake; the device has outstanding advantages of dissipating earthquake energy, eliminating residual displacement and not affecting building use function, and can be widely applied to the earthquake-proof design of a new-built building and the earthquake-proof reinforcement of an existing building.

Description

technical field [0001] The invention belongs to the field of shock absorption technology, and in particular relates to a rotary self-resetting energy consumption device, which can be used for the anti-seismic design of new buildings and the anti-seismic reinforcement of existing buildings. Used in conjunction with self-resetting reinforced concrete frame joints, the structure can be free of damage and residual deformation after an earthquake, greatly reducing structural damage, repair costs and repair time. Background technique [0002] In the seismic design of new building structures in my country, the "three-level" fortification goal is adopted, that is, the structure maintains elasticity under frequent earthquakes; the building may be damaged under fortification earthquakes, but it can continue to be used after general repairs; The next building does not collapse. [0003] The results of earthquake damage in recent years show that traditional earthquake-resistant building...

Problems solved by technology

[0008] The purpose of the present invention is to propose a rotating self-resetting energy-consuming device, which is arranged at the beam-column node or the column-foot node, in order to solve the problem of large residual deformation after the earthquake in the energy-dissipating and shock-absorbing technology, and the arrangement affects the use function of the building. Under the premise of not affecting the building's use function, the existing building is seismically reinforced, and the post-earthquake residual displacement of the reinforced building is eliminated
