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 ...
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 ...
Wavelets based time-frequency analysis techniques in structural engineering
Future design procedures for civil structures, especially those to be protected from extreme loads, will need to account for temporal evolution of their frequency content. Separate time analysis and frequency analysis by ...
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) ...
