Abstract

The reliability of two methods of structural identification is assessed employing noise-contaminated data. The statistical properties of the results of the transfer function approach and those of the modal minimization technique are compared, at different levels of noise, with the exact values of the modal parameters being estimated. Comparison indicates that the modal minimization is a far superior technique for structural parameter estimation using linear models.
