Sustainable preservation of existing infrastructure and sustainable construction of new infrastructure represent goals that are essential for future vitality of economy and prosperity of any society. Structural health monitoring (SHM) emerged in the last two decades as a novel multi-disciplinary branch of engineering, with promising potential to help reaching the above goals. Several SHM methods based on application of various sensing technologies combined with specific data analysis algorithms have been researched, developed and with more or less success applied to real structures. Fiber optic sensing (FOS) technologies have significantly evolved and have reached their market maturity during the last decade. The main widely recognized advantages of these technologies are high precision, stability, and longevity in long terms. But in addition to these advantageous performances, FOS technologies provided with long-gauge and truly distributed strain sensors, which led to the development of new transformative SHM methods based on these types of sensors. Using these methods it is possible to affordably instrument large areas of structure, enabling global, large-scale monitoring based on long-gauge sensors, or integrity monitoring based on distributed sensors. These two approaches are presented in details along with enabling FOS technologies, and illustrated with applications on bridges, buildings, and pipelines.
