Abstract
The present invention relates to a superelastic pull, compression and torsion damper made from shape memory alloy in an engineering structure, which is a device applied to an engineering structure to perform damping shock resistance action. The damper comprises a shape memory alloy wire, clamps, an external steel pipe and an internal steel pipe, wherein one end of the internal steel pipe is positioned in the external steel pipe and is positioned on the same axial line with the external steel pipe; the shape memory alloy wire is fixed to the symmetrical sides of the external steel pipe along a radial direction, specifically, the shape memory alloy wire penetrates from a hole at one side of the external steel pipe, passes through one side of the internal steel pipe, passes through the axial line, threads out from the other symmetrical side of the internal steel pipe, and finally threads out from a hole at the other symmetrical side of the external steel pipe; both ends of the shape memory alloy wire are respectively fixed to the external steel pipe by the clamps. The damper can inhibit opposite rectilinear vibration displacement between structural members and as well as can inhibit opposite rotating vibration displacement between the structural members, and thus, structural vibration response can be inhibited more effectively and structural vibration attenuation can be accelerated.
