8 IPPT Department of Intelligent Technologies Institute of Fundamental Technological Research Passive SHM: off-line identification of loads & damages for a passive black-box system vehicle/structure black-box data Identification of accident scenario (impact forces, location, timing), operational loads ensuing structural damage mass excitations (moving crowd, vehicles) Monitoring of global structure or local substructures Material nonlinearities included

9 IPPT Department of Intelligent Technologies Institute of Fundamental Technological Research Active & passive SHM: Model-free identification measurement data Model-free (non-parametric) identification of dynamic loads (including multiple impacts) structural damages mass excitations (moving crowd, vehicles) Thanks to the VDM no need for any numerical parametric model (e.g. FEM) purely experimental structural characteristics

10 Structural Health Monitoring Truss bridge monitoring system The system consists of two components weigh in motion (WIM) part for identification of the load exerted on rails by passing trains This load will provide input for the SHM system mounted on the bridge. SHM system for collecting dynamic responses of the structure using piezoelectric sensors for assessing the bridge state Wireless data transfer system for transfering collected data to a remote analysis center
