The dynamic behavior of the substructures is characterized by dominant and residual fixed interface normal modes. Interface reduction is accomplished by using a reduced number of characteristic constraint modes. The effectiveness of the proposed model reduction technique is demonstrated by means of a numerical example involving the reliability analysis of a structural system under stochastic excitation.
