Paper Abstract

The currently project is focused on monitoring the reliability, the static and dynamic conditions of the Pedestrian Olympic Bridge in Torino, Italy. Smart sensors based on fiber optic sensors, realized by University of Illinois at Chicago, were installed on the cables. In parallel new low-cost accelerometers and inclinometers sensors, realized by the ChiLab (Italy), were installed on the bridge deck to control statically but also dynamically its behaviour. Acquisition system to collect the data through a continuous monitoring platform, able to pre-process the data, was integrated to manage it locally or in remote way. The performance and reliability of civil infrastructure systems such as bridges are governed by a number of factors including the actual operating and loading environments, complex interactions between structural members and systems, and defect, deterioration and damage mechanisms. These factors are studied dynamically with structural identification of various levels of uncertainty which can be attributed to the fabricated-constructed-erected nature of these systems, variability in site characteristics and conditions, material properties and service loads, and direct exposure to the environment over long life-cycles that are often many decades in length.
