Health Assessment of Structures under Uncertainty
Health assessment of structures using measured dynamic response information has become a major research topic. However, the presence of uncertainty in modeling the structure, characteristics of sensors, and the dynamic response information collected by the sensors is generally overlooked by the profession. A time domain system identification- based procedure is proposed in this paper to assess health of a structure at the finite element level in the presence of all major sources of uncertainty. The noise-contaminated response information needs not be available at all dynamic degrees of freedom. The method is verified using computer generated analytical and actual measured response information.
