Most of the damage identification methods are based on the variations of damage indices defined in terms modal and/or non-modal parameters. Most of simplified methods for structural health monitoring and damage detection are based on the observation of the evolution of the dynamic characteristics associated to the fundamental mode of vibration of a monitored structure. The contribution of higher modes to the dynamic response of multi degree-of-freedom systems is an issue of relevant importance affecting both the design of new structures and the assessment of existing ones. The contribution of higher modes could be effective also in the inverse procedures for structural damage detection. In this paper the Interpolation Evolution Method, previously applied considering only the contribution of the fundamental mode of vibration, has been applied taking into account the contribution of the higher modes. Preliminary results retrieved from a numerical campaign based on nonlinear finite element models excited by several strong motion earthquakes are presented.
