What is A Multistage Damage Detection Approach Using Graph Theory and Water Strider Algorithm about?

Structures usually suffer from natural or artificial damages that might result in shortening their service life and even triggering their collapse. Therefore, vibrational damage detection methods, as cost-effective and nondestructive techniques, are widely investigated by researchers. In the present paper, the modal-strain energy-based two-stage method is enhanced, and a graph-theoretic hierarchical (GHM) method is proposed, which takes advantage of the modal strain energy-based index (MSEBI) and overcomes its potential drawbacks by identifying all damaged elements. This method assigns orders and allocates the computational resources to elements according to the MSEBI as well as the connections represented by a graph model. The water strider algorithm (WSA) is also utilized as an efficient new optimizer, and its results are compared with those of some other well-known algorithms. Several examples are used to substantiate the results and performance of the new GHM framework, showing that the new method outperforms the general classic method, especially when it is combined with the WSA optimizer.
