چكيده فارسي :
In recent years, significant efforts have been devoted to developing non-destructive techniques for damage
identification in structures. Damage detection techniques based on modal testing rely on the fact that the
occurrence of damage or loss of integrity in a structural system leads to changes in the dynamic properties of
the structure. In this paper, an energy index based on mode shapes and their derivative is applied to detect
damage in reinforced concrete beams isintroduced. The effectiveness of the proposed methods is examined
through analytical model on an RC beam. Results illustrate that the energy index is sensitive to damage, and
the proposed method is simple and robust in locating single or multiple damages in a structure.
