The article presents examples of damage localization in numerical models of trusses based on changes in natural frequency. The changes were caused by an additional mass moving on the truss nodes. The results of the localization in several truss bars (top chord, bottom chord, diagonal bars, posts) are presented. The influence of damage size on the localization effectiveness is shown. The differential operator was used in the analyses.
