Bridge-monitoring Program
planning, design and
appropriate
To fully meet the objectives of such a
program, special atten­tion must be given to the
specificities of each bridge throughout this
process.
The primary function of monitoring is to ensure the longevity and safety of a bridge as well as optimizing its
management. To implement corrective measures and
maintenance actions, monitoring must enable the timely
detection of any condition or behavior that could deteriorate the bridge, deem it unsafe or poten­tially result in its
failure.
The monitoring program plays a fundamental role during
the construction phase as it enables the verification of
design hypotheses and construction processes, affecting, in some cases, the construction rate of the bridge
and its overall quality. Most defects are already introduced at the time of construction.
Monitoring also allows performance evaluation of
new materials and technologies used in bridge cons­
truction and rehabilitation. This objective is easily
achieved with fiber optic sensors, since these sensors
effectively integrate in new materials such as fiberreinforced polymer composite. Furthermore, fiber optic
sensors adapt perfectly to long-term monitoring of bridges behavior as well as short-term monitoring of the brid­
ges dynamic behavior under traffic load.
Finally, monitoring can be used as a tool for the “supervised lifetime extension” of bridges approaching the end
of their life or in need of major repair. It ensures that such
bridges are operated safely while allowing the postponement of major investments and traffic disruptions.
