DESCRIPTION:Branko Glišić\, Assistant Professor\nDepartment of Civil and
  Environmental Engineering\, Princeton University\nSustainable preservatio
 n of existing infrastructure and sustainable construction of new infrastru
 cture represent goals that are essential for future vitality of economy an
 d 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 m
 ethods based on application of various sensing technologies combined with 
 specific data analysis algorithms have been researched\, developed and wit
 h more or less success applied to real structures. Fiber optic sensing (FO
 S) technologies have significantly evolved and have reached their market m
 aturity during the last decade. The main widely recognized advantages of t
 hese technologies are high precision\, stability\, and longevity in long t
 erms. But in addition to these advantageous performances\, FOS technologie
 s provided with long-gauge and truly distributed strain sensors\, which le
 d to the development of  new transformative SHM methods based on these ty
 pes of sensors. Using these methods it is possible to affordably instrumen
 t large areas of structure\, enabling global\, large-scale monitoring base
 d on long-gauge sensors\, or integrity monitoring based on distributed sen
 sors. These two approaches are presented in details along with enabling FO
 S technologies\, and illustrated with applications on bridges\, buildings\
 , and pipelines.
