Toward enhancing community resilience: Life-cycle resilience of structural health monitoring systems

Resilience is becoming a vital quality, particularly as our built environment faces increasing risks due to the aging of our infrastructure and climate change. Moreover, the built environment is relying largely on information technology and becoming digitalized. Consequently, it is crucial to ensure in addition to the resilience of structures and infrastructure, the resilience of the structural health monitoring SHM systems which provide information and help sustain and monitor the functionality of the built environment. The process involved in securing resilience throughout the life cycle of monitoring systems includes 1) planning and preparation before acute shock events and daily stressors, 2) absorption of shock events and 3) recovery and adaption afterward, as well as a continuous adaption for the daily stressors. Furthermore, enhancing the resilience of SHM systems contributes to, as well as improves, the resilience of structures and infrastructures. In this article, the life cycle resilience of SHM systems is discussed including community participation in SHM via crowdsensing. Comparisons between the resilience of SHM systems are presented. Results are discussed, and recommendations are offered.
