Structural Health Monitoring (SHM) implies the integrationof nondestructive evaluation methods within a system toenable autonomous state awareness for structural integrity.SHM systems have been optimized to cover wide areas aswell as focus on specific “hot-spots” for both metallic andcomposite structures. They can be configured to monitoradverse “changes” such as fatigue cracks, corrosion, delami-nation, loose bolts, or impact damage either in real-time oron demand. Immediate benefits of SHM include drasticallyreducing inspection costs, minimizing preventative mainte-nance, increasing asset availability, and extending remaininguseful life of structures. Future benefits could include usingSHM data to improve design-margin efficiency for lighter-weight structures, facilitating structural certification and/orquality assurance, and dynamically controlling operatingenvelopes. Over the past few years, there has been rapiddevelopment of SHM technique; many smart sensors andintelligent algorithms have been developed. Advances insensing technologies have also enabled the use of large num-bers of sensors for health monitoring of civil infrastructures.The sensors utilized in a SHM system are required tomonitornot only the structural status including stress, displacement,and acceleration, but also those influential environmentalparameters, such as wind speed, temperature, and the qualityof its foundation. Since a large-scale sensor network needsto be involved in a SHM system, how to deploy it in acomplicated, spatially extended structure and the resulting

best identification of structural characteristics by the dataacquired from those locations will be challenging tasks.

Therefore, in the light of the above considerations, thisspecial issue was launched. Numerous investigators world-wide were invited to contribute their original papers andreview articles on the theme of this special issue.These paperspresent the most recent advances, progress, and ideas inthe field of distributed sensor networks for SHM and itsapplication includes smart, bioinspired, nanometer, wireless,and remote sensing technology; intelligent algorithms andevaluation criteria in design of sensor networks; uncertainty,sensitivity, reliability, and redundancy in vibration moni-toring; vibration data cleaning, compression, mining, andfusing technology; application of large-scale sensor networksfor civil infrastructures.

Zhu et al., the optimalsensor placement of medium-speed mill is conducted usingthe effective independence method and QR decompositionalgorithm.The results showed that the order of modal shapeshad an important influence on the optimization results.
