Damage Detection in Active Suspension Bridges: An Experimental Investigation

Fanhao Meng, +4 more
- 07 Sep 2018 - 
TL;DR: The paper proposes to takes advantage of the presence of active cables and use them as an excitation mean of the bridge, while they are used for active damping, to establish a damage index for each hanger of the suspension bridge.

Modal Identification of a Vibrating Structure in the Time Domain

Yong-Lin Pi, +1 more
- 01 Jan 1989 - 
TL;DR: In this article, a general time domain method for the identification of modal parameters of a linear vibrating structure is presented, in which the vibrational structure is represented by a multivariate autoregressive and moving-average (ARMA) model and the modality parameters are related to the coefficient matrices of the ARMA model.

Structural health monitoring by combining machine learning and dimensionality reduction techniques

Giacomo Quaranta, +5 more
- 01 Jan 2018 - 
TL;DR: A new approach based on the combination of dimensionality reduction and data-mining techniques able to differentiate damaged and undamaged regions in a given structure is presented.

Consistent multi-input modal parameter estimators in the frequency domain

T. De Troyer, +2 more
- 01 Aug 2012 - 
TL;DR: In this paper, consistent multiple-input frequency-domain estimators are presented based on a right matrix-fraction description of the frequency response function, which leads to a fast algorithm in the same way as the least-squares complex frequencydomain estimator (LSCF).

Difference models for identification of mechanical linear systems in dynamics

Danilo Capecchi
- 01 Apr 1989 - 
TL;DR: In this article, it is shown that the behavior of mechanical elastic systems under dynamic actions can be modelled with difference equations which reduce to a very simple form when one-input or free vibration cases are considered.
