“…With the aging of existing structures, the problem of performance degradation has become increasingly prominent, especially for long-span bridges. To ensure structural integrity, structural health monitoring (SHM) has become increasingly important and has received extensive attention in recent years (An, Spencer, & Ou, 2015;Blachowski, An, Spencer, & Ou, 2017;Jesus et al, 2019;Li, Park, & Adeli, 2017;Oh, Kim, Kim, Park, & Adeli, 2017;Sun, Liang, Li, & Li, 2019). However, the complexity and uniqueness of civil © 2021 Computer-Aided Civil and Infrastructure Engineering engineering infrastructure, the limitations of sensing technology, and the variability of operational and environmental conditions make SHM and condition assessment still a challenging task.…”
