Structural Health Monitoring of Periodic Infrastructure: A Review and Discussion

Periodic structure has obtained wide applications in various infrastructures. The structural health monitoring of periodic infrastructures is motivated by the facts that in-service infrastructures are damage-prone, while traditional inspection and nondestructive evolution hardly meet the requirements in continuous surveillance, timely warning and assessment of anomalies, and cost-effective maintenance. In this chapter, the fundamental principles and applications of the periodic structure are first introduced. Then, the recent research activities on the health monitoring of periodic infrastructures using data mining are summarized. It is followed by a review of instantaneous baseline structural health monitoring that was originally presented for diminishing the vulnerability of anomaly detection performance to environmental and operational conditions. Investigations on structural health monitoring using the inherent property of periodic structure are subsequently reviewed, and none of them incorporates both instantaneous baseline and advanced data mining techniques for the anomaly identification oriented classification, prediction, and optimization. Based on the state-of-the-art review, discussions about current investigations and suggestions for future studies are provided in the final section.
