Modal parameter identification from operative responses

2006
Modal parameter estimates of a structure, vibrating under actual loadings and operational conditions, have addressed the interest of researchers during the last years. For all the developed approaches, structures need not be excited by expensive devices, because the modal signature of the structure can be achieved from the knowledge of the system time ...

Identification of Modal Parameters from Inconsistent Data

2002
Most of the recent modal parameter estimators start from the fact that natural frequencies, damping ratios and modal participation factors are global parameters of the measured structure. Measuring the structure in different patches can however cause inconsistencies in the data due to e.g. the mass-loading effect of the accelerometers.
