Example Embodiment

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] As attached figure 1 with 2 As shown, the present invention is a super-elastic self-resetting energy dissipation device, which is mainly composed of a U-shaped groove 1, an inwardly extending steel plate 2, a mild steel energy dissipation plate 3 and a shape memory alloy cable 4. The U-shaped groove 1 consists of two It consists of a parallel steel plate and a vertical steel plate. The inner extension steel plate 2 extends into the middle of the U-shaped groove 1 and is parallel to the two parallel steel plates of the U-shaped groove 1. The end of the inner extension steel plate 2 is one of the vertical steel plates of the U-shaped groove 1. The clear distance between them is not less than 5 cm. The mild steel energy dissipation plate 3 is installed between the parallel steel plate of the U-shaped groove 1 and the inward steel plate 2, and the shape memory...

Abstract

The invention relates to a super-elastic self-resetting energy consumption device, and belongs to the field of energy dissipation and damping of engineering structures. The super-elastic self-resetting energy consumption device mainly consists of an U-shaped groove, an inner extending steel plate, a mild steel energy consumption plate and a shape memory alloy pull cable, wherein the U-shaped groove consists of two parallel steel plates and a vertical steel plate, the inner extending steel plate extends into the middle part of the U-shaped groove and is parallel with the two parallel steel plates of the U-shaped groove, the clear clearance between the end part of the inner extending steel plate and the vertical steel plate of the U-shaped groove is not smaller than 5cm, the mild steel energy consumption plate is arranged between the parallel steel plates of the U-shaped groove and the inner extending steel plate, and the shape memory alloy pull cable is symmetrically anchored at the two sides of the U-shaped groove and the inner extending steel plate in a crossing manner. The super-elastic self-resetting energy consumption device has the advantages that the concept is clear, the processing is convenient, the energy of an earthquake input structure can be effectively dissipated under the condition of strong earthquake, and the super-elastic self-resetting energy consumption device can be widely applied to the engineering structure needing key earthquake fortification.

Description

technical field [0001] The invention relates to the field of energy dissipation and shock absorption of engineering structures, in particular to a superelastic self-resetting energy dissipation device. Background technique [0002] Installing metal energy-dissipating and shock-absorbing devices in engineering structures to reduce earthquake damage has been proven to be a very effective method of seismic fortification, but most of the current metal-type energy-dissipating and shock-absorbing devices have relatively large residual deformation after earthquakes , needs to be repaired or replaced after the earthquake, resulting in an increase in the cost of the entire life of the structure. [0003] Therefore, it is urgent and particularly meaningful to develop a metal energy dissipation and shock absorbing device with strong energy dissipation capability and small residual deformation after an earthquake. Contents of the invention [0004] In order to overcome the shortcomin...
