Intensity fiber optic sensors for civil infrastructures

An optical fiber device for bridge monitoring is presented: it pursues the sensing of traffic loads, such as the passage of a heavy truck. In the present proposal an intensity device especially conceived for monitoring steel bridges is described. The working principle is illustrated and a reference example is conducted by monitoring the behaviour of a steel beam. A testing machine applies vertical loads in different sections of the steel beam, thus simulating the passage of a heavy truck over the bridge. The results are discussed and compared to the theoretical values. The actual monitoring of an existing bridge is also discussed. (A) For the covering abstract see ITRD E127016.
