Annular curvature-related shape memory alloy damping device
The invention belongs to the technical field of civil engineering structure vibration control devices and relates to an annular curvature-related shape memory alloy damping device. The device comprises a bracing boom, an inner/outer soft connection shell, an upper/lower cover plate, an SMA bar/rope, a limit node, an adjusting node and a fixing node. The damping device is connected with a self-standing high-rise structure through the upper/lower cover plate and the bracing boom. The SMA bar/rope is connected with the upper/lower cover plate through the adjusting node and the fixing node. The limit node limits the contact of the SMA bar/rope and the self-standing high-rise structure when the SMA bar/rope deforms. The adjusting node adjusts the initial state of the SMA bar/rope and uses the super elasticity of the SMA bar/rope to provide energy consumption and self-reset capability. The annular curvature-related shape memory alloy damping device is simple in structure, good in energy consumption performance and durability, and capable of achieving self-reset, and the like.
