Cover Story: Following the significant improvement in their properties during the last decade, distributed fiber optics sensing (DFOs) techniques are nowadays implemented for industrial use in the context of structural health monitoring (SHM). While these techniques have formed an undeniable asset for the health monitoring of concrete structures, their performance should be validated for novel structural materials, including ultra-high performance fiber reinforced cementitious composites (UHPFRC). In this study, a full-scale UHPFRC beam was instrumented with DFOs, digital image correlation (DIC) and extensometers. A method for the detection and measurement of opening and closing localized fictitious cracks in UHPFRC is verified. The use of the correct combination of DFO sensors allows the precise detection of microcracks, as well as the monitoring of fictitious cracks’ opening. View this paper
