Statistical Estimation of Changes in the Dominant Frequencies of Structures in Long Noisy Series of Monitoring Data
Figure 1
Examples of sudden and gradual drop of natural frequencies due to structural deterioration. (a) Natural frequencies of a concrete highway bridge derived from accelerometer measurements (modified after [3]) and (b) the extraordinary changes in the natural frequencies of the lateral axis of a timber pedestrian bridge derived from Robotic Total Station measurements (Stiros and Moschas, in review).
