STATISTICAL MONITORING OF STRUCTURES HEALTH

ALESSANDRO FASSO'
Universita' di Bergamo
Abstract.
Modern monitoring of complex structures such as a cable-stayed bridge includes a number of real time operating instruments. In order to detect slow changes, such as foundation settlements or other structural damages, a statistical approach is proposed, which allows for the monitoring system uncertainty assessment and for the modeling of normal dynamics of the structure at hand. The modeling approach allows for block segmenting the whole structure in an appropriate number of simpler sub-structures. Correspondingly, the proposed hierarchical change detector results, first, in a top level single statistics which is time-varying and gives a signal when the overall structure health shifts from the expected behavior. After a signal is given, a battery of lower levels statistics, related to the various model blocks defined above, al-low for diagnosis and localization of the most probable source of drift. In this paper, after introducing the general modeling and detection approach, a case study related to the Certosa bridge in Milan is considered in details.
