摘要

The paper summarizes an effort to apply the NExT and ERArntechnique to phase II of the analytical benchmark structuralrnhealth monitoring problems. These benchmark studies focusrnon a numerical model of a four story test structure, based onrna physical model. Over the past three years, the benchmarkrnproblems have gradually become increasingly challenging,rnand experimental studies are being conducted in parallel withrnthe analytical work. Phase II of these analytical studies considersrnuncertainties in the mass and stiffness of various elei-ments, and minimal damage is induced in the structure.rnResults of the phase II analysis are provided herein.
