چکیده مقاله
Operational Modal Analysis OMA is one of the best and effective methods for health monitoring of structures Any changes in the modal parameters could be a sign of the changes in structural properties or ambient conditions of the structure An important application of system identification in structural dynamics is the determination of natural frequencies and damping ratios during operation In this paper, Continues Wavelet Transform CWT is used to extract modal parameters natural frequencies and damping ratios of Karun III double curved arch dam in Iran Modified Morlet wavelet is used to extract natural frequencies then signal decomposed to single frequency signal to eliminate modes interference to calculate damping ratios exactly using half power method
