An unscented universal filter for joint input-state-parameter estimation of a partially measured system: an application to drive-by structural health monitoring

Drive-by structural health monitoring infers the condition of a bridge from the response of an instrumented vehicle, whose measurements are dominated by the road roughness and the vehicle dynamics. The bridge responses, contact forces and bridge parameters depend on one another through the vehicle-bridge interaction (V...

A Vehicle-Integrated Approach to Digital Twin Deployment for Bridges Through Drive-By Sensing

Ageing bridge infrastructure is a growing global concern, yet conventional Structural Health Monitoring (SHM) systems are costly and difficult to scale, and routine visual inspections remain subjective. Drive-by, or indirect, bridge inspection, in which a sensorised vehicle recovers structural information from vehicle-...
