Damage scenarios with light severity and distributed locations could be detected, localized and quantified using a one-step model updating. In many cases, it enhances the capability of FRF-based model updating with the presence of high noise levels and much less updating data. A numerical simulation on a truss has been validated to show the ability of this technique for damage detection.
