OSMOS - strain measurement on a road bridge
Wednesday, 21 September, 2016 - 00:00

 

The bending of 3 spans of the road bridge is monitored by 8 OSMOS Optical Strands installed on the top and bottom members of the steel frame. Each heavy vehicle passing through is recorded by the Expert System Acquisition, which allows the reconstruction of the evolution of the structure under the effect of each convoy : stresses magnitude in the material, estimation of broaches and identification of vibration modes.
