Paper Abstract

The inconsistency in the data handling capacity of the components of an on-line SHM system has impeded its effective use. To address this problem, this paper presents a new concept for integrated SHM system with several special functional modules such as sensor data compression, interactive data retrieval and structural knowledge discovery. In such an integrated SHM system, streamlined data flow is used as a unifying thread to integrate the individual components of on-line SHM system. Adoption of this new concept will enable the design of on-line SHM system with more uniform data generation and data handling capacity for its subsystems. To examine this concept in the context of vibration-based SHM system, real sensor data from an on-line SHM system comprising a laboratory size steel bridge structure and an on-line data acquisition system with remote data access was used in this study. Vibration test results clearly demonstrated the prominent performance characteristics of integrated SHM system including rapid data access, interactive data retrieval and knowledge discovery of structural conditions on a global level.
