Abstract
Proper identification of the cable’s resonant frequencies is critical to provide an accurate estimate of cable force. The MUltiple SIgnal Classification (MUSIC) algorithm is implemented to estimate cable-stayed bridge cable tensions noninvasively from measured cable motion. This algorithm performs eigenanalysis on the data sequence to estimate and eliminate noise contributions before creating its frequency spectrum, providing a more robust estimation approach than traditional Fourier based frequency spectrums. To aid in the selection of cable frequencies, a comprehensive finite difference cable model is simulated and compared to the estimated MUSIC spectrums.
