Modal Participation Estimated from the Response Correlation Matrix

Abstract: In this paper, we are considering the case of estimating the modal participation vectors from the operating response of a structure. Normally, this is done using a fitting technique either in the time domain using the correlation function matrix or in the frequency domain using the spectral density matrix. In this paper, a more simple approach is proposed based on estimating the modal participation from the correlation matrix of the operating responses. For the case of general damping, it is shown how the resp… Show more

“…The HCT is a relatively regular 15-storey reinforced concrete shear core building located at the corner of Hamilton and Robson in Vancouver, British Columbia, Canada. The HCT vibration responses are a well-known set of data in OMA literature that has been used in several publications [17,[28][29][30][31]. It is also well-known in the modal analysis community for being a difficult multi-dataset application example because is based only on two reference sensors.…”
