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. %U https://ceej.aut.ac.ir/article_893_ad7b1b206130cc7e108d78634e893d55.pdf
