TLDR
In this paper, a novel approach of stochastic subspace identification is presented that incorporates the idea of the reference sensors already in the identification step: the row space of future outputs is projected into the rowspace of past reference outputs.About:

TL;DR: The experimental results demonstrate that capturing the most slight nonlinear variations in the data can lead to improved data normalization and, consequently, better damage detection and quantification performances.

Numerical and experimental evaluation of the dynamic performance of a footbridge with tuned mass dampers
TL;DR: In this article, the authors evaluated the structural response of a footbridge with two tuned mass dampers and found that the damping devices lead to an increase of the effective damping ratio of the critical mode.

Subspace-based algorithms for structural identification, damage detection, and sensor data fusion
TL;DR: This paper reports on the theory and practice of covariance-driven output-only and input/output subspace-based identification and detection algorithms for vibration-based structural analysis and health monitoring of mechanical, civil, and aeronautic structures.

Dynamic identification of a masonry façade from seismic response data based on an elementary Ordinary Least Squares approach
TL;DR: In this article, a low magnitude seismic response of a historical masonry structure, the Santa Maria di Collemaggio basilica, was acquired by a complex monitoring system, where ten FBA accelerometers, nine placed on the basilica facade and one on the ground level, recorded respectively the base accelerogram (Input) and the structural response (Output).

In-Flight Vibration Monitoring of Aeronautical Structures
TL;DR: In this paper, a combination of ground vibration tests and in-flight tests is used for this purpose, and various sensor data are recorded, typically from accelerometers, based on these data, the aircraft dynamics are identified through modal analysis or structural identification.
