OSMOS WiM+D®: Real condition use on an innovative Bridge Weigh-in-Motion solution on the Auzouer bridge (France)


As a pioneer in Structural Health Monitoring (SHM), OSMOS has initiated decisive research projects and relies on highly recognized scientific partners.

OSMOS takes special care about keeping its research updated at a high-end level and knowledge enhancement about infrastructures. Our goal is to contribute to the sustainability of these strategic infrastructures, which ensure the proper functioning of local and regional economies.

The OSMOS WiM+D® automated solution is the result of research studies carried out in collaboration with the Gustave Eiffel Institute, Le Mans University and the Cabinet Ehrlacher, whom we would like to thank for their valuable contribution.

Thanks to the support of the company Cofiroute and Mr Nicolas Bardou, the system has been tested since February 2019 on the Auzouer bridge, a precast prestressed concrete beam girders bridge overcrossing a highway in France. The objective of this real condition experiment was to prove the robustness of the solution over a long period of time and to improve even more the performance of the system.

At the IABSE Congress Ghent 2021 organised by the International Association for Bridge and Structural Engineering, the study will be published as a research paper co-authored by:

  • François-Baptiste CARTIAUX, Véronique LE CORVEC, Jorge SEMIAO (OSMOS Group SA, Paris, France)
  • Bernard JACOB, Franziska SCHMIDT (Université Gustave Eiffel, Champs-sur-Marne, France)
  • Alexandre BROUSTE (Laboratoire Manceau de Mathématiques, Le Mans University, Le Mans, France)
  • Alain EHRLACHER (Cabinet Ehrlacher, Grisy-Suisnes, France)

OSMOS Group would like to congratulate every member of the team who contributed to the research studies about the development and improvement of the OSMOS WiM+D® solution and salutes the technical performance achieved.
