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:

Measured properties of structural damping in railway bridges
TL;DR: In this article, a non-proportional damping index is presented as a basis to determine the influence of different sources of nonproportionality in the damping matrix (as the ballast layer under the track).

Recursive stochastic subspace identification for structural parameter estimation
Chih-Chen Chang,Zhen Li +1 more
TL;DR: A recursive SSI method which uses an unconstrained optimization technique to track the signal subspace is employed and can identify and track the time-varying modal properties of the building under ambient condition.

Mode shape expansion with consideration of analytical modelling errors and modal measurement uncertainty
TL;DR: In this paper, the perturbed force is considered as an unknown vector that contains the discrepancies in structural parameters between the analytical model and the tested structure, and a regularization algorithm based on the Tikhonov solution incorporating the L-curve criterion is adopted to reduce the influence of measurement uncertainties and to produce smooth and optimised expansion estimates in the least squares sense.
