The invention discloses a high-energy-consumption tension-compression and rotation recoverable damper, and belongs to the technical field of seismic resistance and energy consumption. The problems that an existing restorable damper is complex in structure and single in energy consumption form are solved. The two side walls of a first push-and-pull piece are fixedly connected through three high-strength bolts arranged side by side in the horizontal direction, two first long holes and a second long hole located between the two first long holes are formed in a second push-and-pull piece side by side, and the second push-and-pull piece is located between the two side walls of the first push-and-pull piece; and the three high-strength bolts are arranged in the second long hole and the two firstlong holes in a penetrating mode in a one-to-one correspondence mode, the height of the second long hole in the vertical direction is smaller than that of the first long holes in the vertical direction, in the initial state, four first limiting clamps and two second limiting clamps are distributed in a rectangular mode, and each second limiting clamp is connected with the two adjacent first limiting clamps through shape memory alloy wires.
Description
technical field [0001] The invention relates to a high-energy-consuming tension-compression and rotation-restorable 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 e...
