Abstract/Description: With the increased aging and deterioration of civil infrastructure systems, it is crucial to develop an effective and economical structural health monitoring system. Current structural health monitoring systems are burdened by disadvantages rendering them inefficient or not economically viable. In response to this problem, the in-situ triboluminescent optical fiber (ITOF) sensor has been developed for applications within cementitious structures. Four point bend tests were carried out on reinforced concrete beams with integrated ITOF sensors so as to evaluate the performance of the sensor. With this study, the ITOF sensor's potential to provide in-situ and distributed real time damage detection within concrete structures has been demonstrated. Reinforced concrete beams instrumented with the ITOF sensor provided warning signals and real time feedback prior to the failure of the beam through triboluminescent signal peaks and demonstrated the potential as a viable SHM system. Both the length and sensor location within the reinforced beams were tested. Test results indicated that a longer sensitized region of the ITOF sensor and a sensor placed closer to the tension face of the beam yielded higher damage (triboluminescent) response signals.
