When a very low damage occurs, the undamaged structural response totally overlaps the damaged oneeitherintimedomainorinfrequencydomain;ontheotherhand,byconsideringsomecharacteristicsoftheanalytical signal, such as the phase, it has been possible to develop a damage identiﬁcation procedure thatallows the identiﬁcation and localization of damage even if the structure experiences multiple damages atthe same time. This procedure is also robust with respect to the presence of measuring noise. In order toassess the validity of the proposed damage identiﬁcation procedure, numerical applications on singledegree of freedom and 2 DOF and 4 DOF are presented using data records perturbed by measuring noisetoo.
