Abstract
Conventional finite element updating techniques make use of measured frequency
response functions and modal parameter estimates to update the FE model parameters.
This paper presents a new technique to update the FE model from outputonly
transmissibility measurements. A transmissibility function is defined as the
ratio between two measured or calculated responses. In general, the poles that are
identified from transmissibility measurements do not correspond with the systems
poles. The usage of transmissibility functions for output-only FE model updating
and optimization is investigated. The effectiveness of the proposed technique will
be illustrated by means of a case study.
