Dynamic characteristic of the forth road bridge estimated with GeoSHM

Researchers have successfully used GNSS and Earth Observation technologies to extract dynamic characteristics of the Forth Road Bridge, demonstrating their potential for structural health monitoring. The study revealed that lateral movements are primarily driven by wind loading, while vertical displacements under normal traffic loads can reach 0.3 meters. The first natural frequencies of the bridge's middle span were identified at 0.065 Hz (lateral), 0.15 Hz (longitudinal), and 0.104 Hz (vertical). These findings highlight the effectiveness of GeoSHM in assessing operational conditions, offering a valuable tool for bridge owners.
