Abstract

This paper provides new approaches to detect damage in reduced order systems which are insufficiently instrumented. In the framework of a state space formulation the paper will show that the use of the strain energy allows to define damage indexes able to provide information about damage to all the degrees of freedom with and without instrumentations. The key points of the approaches will be discussed with reference to the case of concentrated forces and seismic action. The efficacy of the approach will be showed by means of numerical applications. The effect of the noise will be finally investigated.
