Statistical system identification of structures using ARMA models
The present study focuses on the estimation of the modal properties, i.e., natural modal frequencies, modal damping ratios, and mode shapes, of a structural system under ambient vibration based on the response data of the ...
System identification of dynamic structural systems using continuous-time domain methods
Structural system identification is the process of deducing the properties of a structural system from its measured response to ambient vibration by fitting a mathematical model. The objectives of this study are to: (1) ...
Experimental system identification of model frames using frequency-domain and time-domain methods
Two different metal test frames are excited using the impact-hammer method. The force-input and specific acceleration-output time-histories were recorded, and through frequency-domain, and time-domain structural system ...
