Structures suffer local damages due to various reasons. If these damages are not identified, they could be aggravated by natural disasters such as earthquakes or artificial factors such …
In this paper, we investigate changes in the mechanical properties of complex structures using a combination of the discrete model, Fast Fourier Transform (FFT) analysis and deep …
This research proposes a new indicator based on change in a vibration signal's probability spectrum centre to assess structural change. It relies on the change of a central position of …
