Structural health monitoring (SHM) is the usage of modern sensing technologies, communication algorithms, and advanced data mining and management systems to monitor the operational environments and loadings as well as the structural responses in real time, to effectively evaluate the structural health condition and safety performance and to instruct the daily structural inspection and maintenance, which is a multidiscipline and cutting-edge research field in civil engineering [13]. In the past several decades, a great amount of long-term SHM systems have been designed and implemented worldwide on civil engineering structures such as large-scale bridges and high-rise buildings [4]. With these SHM systems, a vast ocean of information relevant to the structural responses and behavior can be continuously obtained in real time. The measurement data are valuable in detecting structural anomalies and damage at an early stage to ensure operational safety and in providing authentic information for timely assessment after disasters and extreme events.

A critical issue of great concern is how to extract the features inherent in the monitoring data for structural performance assessment targeting life-cycle safety, reliability, durability, and sustainability. Therefore, intelligent computational methodologies and approaches, such as artificial neural networks, fuzzy logic systems, and genetic algorithms, are always desired. Numerous investigators worldwide were invited to contribute their original papers and review articles on the theme of this special issue.

A total of 44 technical papers are received and 25 out of them are finally accepted for publication in this special issue. The first seven papers address novel sensing technologies in SHM.
