Expansion of experimental mode shape from operational modal analysis and virtual sensing for fatigue analysis using the modal expansion method
TL;DR: A new quality measurement is introduced – the normalised error of fatigue damage – for strain estimation intended for fatigue analysis and, based on this study, expansion of experimental mode shapes has the potential to reduce errors in stress/strain estimation.

Structural sensing with deep learning: Strain estimation from acceleration data for fatigue assessment
TL;DR: In this article, the authors used fatigue analysis to accurately estimate the fatigue of civil structures during their life span, and found that many of the civil structures experience significant vibrations and repeated stress cycles during their lifetime.
Journal ArticleDOI
Estimation of the full-field dynamic response of a floating bridge using Kalman-type filtering algorithms
TL;DR: A case study of full-field dynamic response estimation of a long-span floating bridge: the Bergoysund Bridge in Norway is presented, demonstrating that the displacements and the accelerations can be estimated at unmeasured locations with reasonable accuracy when the wave loads are the dominant source of excitation.

An augmented Kalman filter for force identification in structural dynamics
TL;DR: It is shown how, in the collocated case, more accurate results can be obtained with the augmented filter due to its incorporation of modeling errors, while better solutions are produced by classical deterministic methods as Dynamic Programming in which only the forces are estimated, and not the states as well.
Journal ArticleDOI
A dual Kalman filter approach for state estimation via output-only acceleration measurements
TL;DR: In this article, a dual implementation of the Kalman filter for estimating the unknown input and states of a linear state-space model by using sparse noisy acceleration measurements is proposed, which avoids numerical issues attributed to unobservability and rank deficiency of the augmented formulation of the problem.

TL;DR: In this article, an algorithm is presented for jointly estimating the input and state of a structure from a limited number of acceleration measurements, based on an existing joint input-state estimation filter derived using linear minimum-variance unbiased estimation.
