Abstract:
Although several publications have been presented on health monitoring of existing structures, the issue still needs further investigation. In this respect, a model updating approach is suggested in this paper that detects structural damages in beams via a meta-heuristic optimization algorithm (Charged System Search (CSS)). The model detects damages in beams by means of an objective function based on natural frequencies and mode shapes, and the effects of measurement noise are taken into consideration to make the results more realistic. The method is validated on several numerical examples the results of which indicate the efficacy of the suggested strategy
