Outline of Final Research Achievements

This study is a structural health monitoring using external noise. Building diagnostics using the slight vibration caused by wind or traffic noise is effective for a structural health monitoring. However, selecting the optimum length of windowing is an important key for passive diagnostics. This study proposed a cepstrum ratio and selecting the optimum windowing length based on it. From the model experiment, it was shown that the estimation error of the building eigenfrequency is converged for the cepstrum ratio over 0dB.
