2nd "Connected Bridges" experiment on a footbridge in Paris

07/12/2023
The City of Paris is the 2nd partner after the Conseil Départemental de l'Isère (Pont de Lagnieu) to have volunteered to make its bridges available to test the autonomous/connected sensor solution for monitoring the Claude Bernard footbridge in the 19th arrondissement of Paris.

Innovative monitoring

of engineering structures

This new instrumentation is part of the "Connected Bridges" call for projects led by Cerema* as part of France Relance. This programme aims to support innovative monitoring projects for engineering structures. Apave and its partners (Sercel, Ville de Paris and the Conseil Départemental de l'Isère) have been selected on the basis of their application to monitor engineering structures using autonomous sensors.

 

* Cerema (Centre d'études et d'expertise sur les risques, l'environnement, la mobilité et l'aménagement) is a public body dedicated to supporting public policies, under the dual authority of the Ministry for Ecological Transition and the Ministry for Territorial Cohesion and Relations with Local Authorities.

The City of Paris is testing

the Apave solution

For this experiment, the City of Paris, in a consortium with Apave and Sercel, has chosen the Claude Bernard footbridge to install a high-tech analysis system that will enable real-time monitoring of the vibrations suffered, the integrity, health and maintenance of the structure.

More specifically, this experiment will enable us to characterise the actual behaviour of the footbridge, to compare it with that predicted and to qualify the structure's level of flexibility. 14 sensors have been installed on the structure, and the data is routed to the Sercel and Apave clouds using 2 gateways powered by 2 solar panels. The system is completely self-sufficient in energy.

 

The sensors developed by our partner Sercel are installed directly on the gateway. They enable precise measurements to be taken of the behaviour of a structure and precise data to be retrieved on its characteristics.

 

The aim is to maintain and extend its lifespan, detect and predict its failures and thus contribute effectively to the prevention of any risk, and thus ensure the safety of people crossing it.

The data collected as part of the instrumentation process will enable the engineering structures department to improve its knowledge of the structure and to better plan maintenance and repair work...

Focus

Installed in 2015, the Claude-Bernard footbridge crosses the Paris ring road, linking Paris to Aubervilliers. With its 98-metre curves and 60-metre span, it is located in the 19th arrondissement of Paris. It crosses the ring road between Rue Emile Bollaert in the 19th arrondissement and Rue de la Gare in Aubervilliers.
