Modal identification of structures from ambient vibration, free vibration and seismic response data via a subspace approach.
This work presents a unified procedure for determining the natural frequencies, modal damping ratios and modal shapes of a structure from its ambient vibration, free vibration and earthquake response data. To evaluate the coefficient matrices of a state space model, the proposed procedure applies a...
