Novel damping plate set with multi-order yielding and deformation restorability

Abstract

The invention discloses a novel damping plate set with multi-order yielding and deformation restorability. The damping plate set is formed by overlapping a limiting combination plate, an arch weakening SMA splicing plate and a reinforcing buckling restraining plate and comprises an L-shaped slotted steel plate, an arch weakening low-yield-point steel plate, arch single-side weakening SMA plates, the reinforcing buckling restraining plate and bolts; the side plate, where a groove is formed, of the L-shaped slotted steel plate is provided with a convex curve which is matched with the groove formed in the arch weakening low-yield-point steel plate in an adaptive mode to form the limiting combination plate; and the arch weakening SMA splicing plate is formed by splicing the two arch single-side weakening SMA plates. By means of the design of the limiting combination plate with the convex curve matched with the groove in the adaptive mode and the combination of the low-yield-point steel plate with good energy dissipation capacity and the SMA plates with deformation restorability, the novel damping plate set which can achieve large deformation and has good energy dissipation capacity and deformation restorability is provided, and the novel damping plate set has the advantages of being simple in structure, easy to install, remarkable in energy dissipation and self-resetting effect and the like.

Description

technical field [0001] The invention belongs to the anti-seismic field of structural engineering, and in particular relates to a novel damping plate group with multi-stage yield and deformation recovery. Background technique [0002] In recent years, with the continuous innovation of anti-seismic technology, structural vibration control has been introduced into the anti-seismic design of structures. The application of energy dissipation and vibration reduction technology in structures can effectively reduce the response and loss of structures under earthquakes. It is an effective anti-vibration technology. Energy dissipation and vibration reduction technology is to design some components in the structure as energy-dissipating components or install damping devices in certain parts of the structure to consume the energy when the structure vibrates, effectively reduce the vibration stress of the structure, and enhance the seismic performance of the structure. In addition, the ...
