This study proposes an efficient Bayesian, frequency-based damage identification approach to identify damages in cantilever structures with acceptable error rate, even at high noise levels. The catenary poles of electric high-speed train systems were selected as a realistic case cover the objectives this study. Compared other detection approaches described literature, proposed is efficiently ab...

A novel vibration-based method (VBM) for damage identification, nodal line active modulation (NLAM), is proposed in this study. Unlike traditional VBMs, the NLAM can identify by taking advantage of effect, which that when a defect located on lines, dynamic responses structure remain nearly unchanged. The basic idea introduced through simply supported beam. In numerical study, we have discussed ...

Metaheuristic algorithms have known vast development in recent years. And their applicability engineering projects is constantly growing; however, deferent exploration and exploitation techniques cause the problems to favor some over others. This paper studies damage identification steel plates using Frequency Response Function (FRF) indicator detect localize healthy damaged structure. The stud...
