High-energy-consumption anti-tension-torsion recoverable damper

Abstract

The invention discloses a high-energy-consumption anti-tension-torsion recoverable damper, and belongs to the technical field of anti-seismic energy consumption. The problem that an existing recoverable damper is small in energy consumption and complex in structure is solved. An inner sleeve penetrates in an outer sleeve, the end, close to a second push-pull rod, of the inner sleeve is fixedly provided with a second baffle, one end of the second push-pull rod is fixedly connected with a second baffle, one end of a first push-pull rod penetrates in the inner sleeve, an energy consumption pipe is coaxially embedded between the first push-pull rod and the inner sleeve, a plurality of first clamps are fixedly arranged on the first push-pull rod in the circumferential direction, a plurality ofsecond clamps are fixedly arranged on the second push-pull rod in the circumferential direction, a plurality of third clamps and a plurality of fourth clamps are fixedly arranged on the outer wall ofthe outer sleeve and arranged in the circumferential direction of the outer sleeve, the first clamps and the third clamps are connected in a one-to-one correspondence mode through shape memory alloy,and the second clamps and the fourth clamps are connected in a one-to-one correspondence mode through shape memory alloy.

Description

technical field [0001] The invention relates to a high-energy-consuming, tensile-torsion-recoverable damper, which belongs to the technical field of anti-seismic energy consumption. Background technique [0002] With the development of building anti-seismic technology, the collapse of building structures and the number of casualties after earthquakes have been effectively controlled, and the direct and indirect economic losses caused by earthquakes have been widely concerned. Therefore, the functional restorability of building structures and components has become a new research hotspot. The damper is a component that reduces the earthquake damage of the structure and consumes the earthquake energy. Its functional recoverability can ensure the rapid recovery of the main structure of the building structure after the earthquake, so as to reduce the economic loss. At present, the following two problems generally exist in the recoverable damper: [0003] 1. The energy consumpti...
