N2 - Optimal-matrix update identification techniques produce, through a constrained optimization approach, updated property matrices (i.e., stiffness, damping and mass matrices) that more closely match the structure modal properties as determined by test. In this paper, a strategy for applying connectivity-preserving techniques to focus the update on areas of model uncertainty is presented and evaluated. Data from a damage location situation in a laboratory experiment of a cantilevered truss-beam structure is used to illustrate the use and performance of focussed masking of optimal update techniques.
