Challenges in applying the vibration- based damage detection to civil structures

With the development of sensor,signal acquiring and processing technologies,a largernumber of vibration-based damage detection methods have been proposed for civil engineering structures in recent years.However,we have difficulties in applying these methods to real structures in operating environments.After a brief introduction to the vibration-based damage detection methods developed over the last 20 years and their applications,this paper presents an analysis of the primary challenges in applying these damage detection methods,and provides an overview of the associated solutions.It concludes with a discussion of critical issues for future research in the area of vibration-based damage detection.
