Abstract:
In recent years, significant efforts have been devoted to developing non-destructiv e techniques for damage identification in structures. Damag e detection techniques based on modal testing rely on the fact that the occurrence of damage or loss of inteegrity in a structural system leads to changes in t he dynamic properties of the structure. In this paper, an energy index based on mode shapes and their deriv ative is applied to detect damage in reinforced concrete bea ms 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 r obust in locating single or multiple damages in a structure.
