Abstract：The influence of shape memory alloys (SMAs) on the vibration performances of concrete columns were studied through initial displacement method. In this study, SMA reinforced concrete columns are fabricated by embedding SMA wires with different phases. The experiment includes two parts: one is the free vibration test; the other is the vibration test with current activation. The test results indicate that the state (or phase) of SMAs has evident influence on the damping ratio of the concrete columns. Moreover, the recovery force generated during the phase transformation has great influence on the frequency of the concrete columns. Therefore, SMAs can be utilized to change the dynamic properties of concrete members or structures to control the structural vibration effectively.
