Abstract:
The paper presents the realization and testing of Textile Reinforced Concrete (TRC) panels sensorized with distributed Fiber Optic Sensors (FOS). Proper procedures for fastening the sensor to the textile before its insertion as panel reinforcement, as well as for protecting the sensor during and after concrete casting were investigated. Two samples were then realized, one reinforced with traditional steel mesh, one reinforced with sensorized textile mesh. FOS and reference electrical strain gages were applied to both. The panels were tested in flexure up to failure, in order to investigate the effect of mesh substitution and of strain monitoring by means of the embedded distributed FOS, interrogated with Brillouin technique. The paper discusses the obtained results, which confirm the feasibility of the pro-posed set-up, though evidencing the need of few enhancements to the sensor em-bedding technique.
