Resilience assessment of a fully automated modal-based SHM system by shaking table tests
Abstract eng: Vibration-based damage detection techniques offer interesting opportunities for Structural Health Monitoring (SHM) of strategic structures in seismically prone areas. However, earthquake shaking can cause saturation of sensors if the measurement chain is optimized to record the ambient vibration response only. This can affect the reliability of the SHM system. In the present paper, the resilience to earthquake shaking of a fully automated modal based SHM system is assessed taking advantage of specific experimental tests. The results achieved in the context of the present study show that, even in the presence of a measurement chain not specifically designed to resolve the high amplitude vibrations induced by earthquakes, a reliable monitoring of the modal properties before and after the ground motion by means of automated Operational Modal Analysis techniques is possible, thus ensuring a near real-time remote assessment of the structural health.
