Reference-based stochastic subspace identification for output-only modal analysis
Bart Peeters,Guido De Roeck +1 more
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:

Decentralized Infrastructure Health Monitoring Using Embedded Computing in Wireless Sensor Networks
Kosmas Dragos,Kay Smarsly +1 more
TL;DR: A methodology to fully decentralize the condition assessment process is presented and the development of embedded algorithms and numerical models to be embedded into the wireless sensor nodes, i.e. the monitored structure is divided into substructures where each sensor node is responsible for monitoring one substructure are showcased.

Structural health monitoring - a review with the emphasis on low-frequency methods
TL;DR: Structural Health Monitoring (SHM) is a fast-developing, interdisciplinary field of research as discussed by the authors having its roots in vibroacoustics and non-destructive testing and evaluation Fast development is due to the fact that SHM is heavily stimulated by the engineering problems of maintenance and safe operation of technical infrastructure.

An analytical perspective about structural damage identification based on transmissibility function
Liangliang Cheng,Alfredo Cigada +1 more
TL;DR: An analytical approach has been investigated to demonstrate how to localize damage components caused by mass and stiffness change in terms of multiple-degree-of-freedom mass–spring–damper system, based on the inherent analysis between the transmissibility functions for any two consecutive masses.

Structural performance evaluation of a steel-plate girder bridge using ambient acceleration measurements
TL;DR: In this paper, an alternative method is proposed using an excited response part of full measured ambient acceleration data by ordinary traffic on a bridge without traffic control, based on the modal properties extracted from the ambient vibration data.
