摘要：

The displacement response and the frequency-amplitude characteristics of a frame structure with pre-strained shape memory alloys (SMA) tendons were analyzed by finite element method. The SMA braced structure is subjected to a harmonic force excitation. The effects of the pseudoelastic damping of SMA on the displacement response of the braced structure were discussed in three aspects including initial pre-strains of SMA, forcing magnitudes and operating temperatures. It is found that the pseudoelastic SMA can suppress the vibration of structures effectively.
