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.
Tutti gli interessati sono cordialmente invitati a partecipare.
