Measurement of forces and impacting pressures on a bridge pier subjected to swell

Instrumentation of a bridge pier subjected to breaking waves in the coastal zone: the metrology implemented allows the acquisition of pressures located at ten points of the pier via piezo-resistive sensors, but also of overall efforts via a load cell located under the pile. This double acquisition allows the characterization of the structure from a global point of view, but also to identify targeted areas subjected to impacting pressures due to the wave breaking.
