This paper limits the discussion to the vibration-based SHM. In recent decade SHM using vibration-based technology is going along three directions: (1) dense-measurement on structures/bridges on site or laboratories to make the measurements near by the locations where the damages may occur, (2) improved sensing technology for more effective data collection, networking and data transfer and (3) methodologies to analyze the data in order to extract the signals to characterize the health status of structures. All these works could make sense on SHM as long as the signal to characterize the localized damage was included in the data observed in the structures. This paper discusses how to ensure such signal can be observed in a structure. The new findings of the research show that in order to successfully monitor the health status of a structure it is necessary to make the local modes measurement.
