Loss of synchroniza- tion mostly concerns modern wireless SHM systems; however, synchronization discrepancies may also occur in cable-based systems in case multiple data ac- quisition units without global clock management are used. This paper presents the implementation and validation of a concept towards synchronizing SHM da- ta records containing structural response data, which is imperative for obtaining information valuable for accomplishing monitoring objectives. Specifically, the performance of a cross spectrum synchronization approach reported in a recent study, which builds upon cross spectral density phase angles of structural re- sponse data transformed into the frequency domain, is investigated with struc- tural response data from real structures. The cross spectrum synchronization approach is implemented into a wireless SHM system and into a cable-based SHM system, and it is validated through tests on a laboratory shear-frame struc- ture and through field tests on a pedestrian bridge, respectively. The validation test results prove that the cross spectrum synchronization approach is capable of complementing traditional clock synchronization protocols, thus enhancing the accuracy of SHM outcomes.enCross-spectrum-based synchronization of structural health monitoring dataConference Paperhttps://smarsly.files.wordpress.com/2022/03/smarsly2022j.pdfOther
