Abstract
To identify structural damages many different methods have already been developed. Evaluating the performance of these methods is not a convenient task because they have been applied to different structures or constructed for specific purposes. Most of these methods use model-updating techniques, as a tool, to detect and assess damage. On the other hand some methods, including Energy Index Method, use the concept of strain energy to detect damage. This paper tries to compare the performance of Energy Index method with the performance of a model-updating-based model. In order to facilitate the comparison of various damage identification methods a structure proposed by the IASC-ASCE Task Group on Structural Health Monitoring is considered as the benchmark structure. Finally, the effects of measurement noise and incompleteness of data on the performance of the proposed algorithm are investigated.
