Firstly, modal responses were estimated by the application of robust second-order blind identification technique on the measured vibration signals. And then, modal shapes were extracted from the de-mixing matrix above. Finally, frequency and damping ratios could be obtained from the modal responses using each single degree of freedom mode.
