TL;DR: In this article, a statistical damage identification algorithm based on frequency changes is developed to account for the effects of random noise in both the vibration data and finite element model, and the structural stiffness parameters in the intact state and damaged state are derived with a two-stage model updating process.

TL;DR: In this paper, a new eigensolution technique via iterated dynamic condensation is proposed, which retains all the inertia terms associated with the removed degrees of freedom in an iterated form, which generates the reduced mass matrix similar to that obtained in the Guyan reduction method with a frequency-dependent perturbed term.
