Load testing of a composite footbridge with strain and displacement measurements
The innovative foot deck was designed and implemented within an existing bridge in Rzeszów. DFOS fibres were integrated within the composite panels during their production (infusion). This way, the sensors became an integral part of the entire structure. Appropriate fibres arrangement and their full integration inside the composite panels allowed us to utilise the idea of both strain sensing with the EpsilonSensor and vertical displacement sensing with 3DSensor. The ready-to-use smart panels were delivered on-site.
DFOS Sensors Installed: EpsilonSensor and 3DSensor
Project challenges
Benefits of using the DFOS monitoring system
Results of using the DFOS monitoring system
Example DFOS results (both strains and displacements) obtained during load tests are presented on the plot graph. Very good agreement with reference techniques proved the accuracy, reliability and high-quality performance of the applied solution, which is in line with the basic design of Nerve-Sensors.
