Abstract
A strategy is developed to reduce the poor conditioning of estimation equations used in the parametric identification of finite element models for linear elastodynamic structures. It is based on the simultaneous exploitation of synthesized responses resulting from different boundary condition configurations obtained by introducing fictive constraints. This approach is then applied to an updating procedure employing partial output residuals constructed from the eigensolutions of the model and structure. Two numerical examples illustrate the potential of this method.
