20.500.12556/DiRROS-25539 Monitoring the dynamic sensitivity of the Solkan footbridge to user-induced excitation This paper presents a comprehensive monitoring study of the dynamic sensitivity of the Solkan footbridge in Slovenia, with a focus on its response to user-induced actions. An extensive ambient vibration measurement campaign was carried out, during which 26 triaxial accelerometers were strategically deployed along the bridge to capture its modal characteristics in all three spatial directions. The structure’s dynamic response was monitored under both regular pedestrian traffic and elevated loading conditions during a local marathon event, allowing for the assessment of its behaviour across a broad spectrum of realworld scenarios. Preliminary measurements revealed reduced pedestrian comfort, primarily due to resonance effects resulting from bridge–user interaction. The study highlights the importance of field-based dynamic assessments in diagnosing performance issues and informing mitigation strategies. The findings contribute to the advancement of resilient and dynamically efficient design and maintenance practices for pedestrian bridges. modal model validation footbridges ambient vibrations dynamic sensitivity user-induced excitation validacija modalnega modela brvi ambientalne vibracije dinamična občutljivost vzbujanje s strani uporabnika true false true Verlag der Technischen Universität Graz Angleški jezik Slovenski jezik Neznano 2026-01-22 12:07:02 2026-01-22 12:09:47 2026-01-24 03:42:00 0000-00-00 00:00:00 2025 0 0 Str. 1083-1087 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2025-09-06 624 10.3217/978-3-99161-057-1 259847683 256692995 http://doi.org/10.3217/978-3-99161-057-1-163 0 7d8ff3b1-f782-11f0-a15d-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=38721 Zavod za gradbeništvo Slovenije 0 0 0
