ABSTRACT
ABSTRACT: Performance control of brides based on structural health monitoring has been carried out as an a posteriori task, where information extracted in situ is compared with reference baselines which must be acquired while the structures are undamaged and unchanged. In addition, the vast majority of structural health monitoring techniques relies either on numerical or data-driven techniques. While the first type is computationally inefficient to be applied in on-line (real-time) strategies, the second type generally provides information with lesser detail, which may allow detecting structural changes but generally does not allow locating or classifying them. The present work presents an innovative on-line methodology with the ability to detect, locate and classify structural changes without resorting to baseline comparison. It consists of combining data-driven techniques and numerical analysis, and its effectiveness is validated, in the present paper, by applying it to time-history numerical simulations of the International Guadiana Bridge, located in the southwest of the Iberian Peninsula.
