Bridge
Innovation and development
FSI optical fiber systems are the new frontier of Structural Monitoring of bridges and viaducts, overcoming the limits of the approximation resulting from discrete measurement systems.
The FSI fiber optic sensors can be used not only to investigate displacements, strain and loads, vibrating modes, fatigue resistance, inspection tests and lifespan during the operating stage of a bridge, but it’s also very interesting to monitor a bridge during the launching phase, the phases of assembling and construction and the phase of strip out of piles and spans, especially when they are affected by external loads as wind pressure, earthquakes or landslides.
