摘要
An approach to identify modal parameters from output-only transmissibility measurements is introduced. In general, the poles that are identified from transmissibility measurements do not correspond with the system's poles. However, by combining transmissibility measurements under different loading conditions, it has been shown that modal parameters can be identified. In this paper the proposed technique is recapitulated and validated by means of an experimental test on a clamped beam. (c) 2007 Elsevier Ltd. All rights reserved.
