The aim is to develop an integrated approach for monitoring the structural health of the Rayhanna Bridge using operational data and vibrations.
Installed accelerometers for tri-axial data collection over 3 weeks under live traffic conditions.
Conducted operational modal analysis to identify stable frequencies at 2.5, 5.1, and 7.8 Hz.
Developed a physics-based vehicle–bridge interaction model and decision support tools for resonance management.
Identified a high-risk resonance band for vehicle speeds between 12 and 19 m/s linked to observed amplification phenomena.
Demonstrated that a tuned mass damper targeting the 5.1 Hz mode attenuates resonant peaks by 3–5 dB.
Created operational strategies for bridge interventions, including speed management and prioritization of bearings.
