In this paper,the working principle of shape memory alloy(SMA)super-elastic tendon as an energy dissipation device is analyzed.The super-elastic restoring capability model of the SMA energy dissipation device is also studied.Such device was installed on a structural model of two-story frame and vibration tests were conducted on the frame.Earthquake response analysis was carried ort for frame structures installed with SMA energy dissipation tendons and with steel wires respectively.Test and numerical simulation results show that the SMA energy dissipation tendon can reduce the vibration response of the structure effectively and proves to be a device of good behavior for energy dissipation and vibration control.
