Long-term reliability assessment of OBR based DOFS on reinforced concrete elements

摘要：

　　The authors conducted a laboratory experiment where two reinforced concrete beams were instrumented with a Distributed Optical Fiber Sensors that were adhered to allow the measuring of strain on four different longitudinal segments on their bottom surface.A fatigue test was then conducted on these elements where the load range was the one expected on a standard highway bridge between its permanent and the additional traffic load.Furthermore,each longitudinal segment of the DOFS was adhered to the concrete using a different adhesive in order to assess the optimal one in these fatigue conditions.The obtained data is then compared with strain gauges that were also instrumented on the concrete beams.
