Modern glued-laminated timber (glulam) footbridges are usually designed as slender structures and easily influenced by human-induced vibrations, because of their low stiffness, damping and modal mass. If the main vibration applicability requirements cannot be met, some measures such as tuned mass dampers (TMDs) should be taken to reduce the vibration. This paper discusses the vibration serviceability assessment of a glulam model bridge subjected to realistic pedestrian traffic conditions, and the optimal design of multiple tuned mass dampers (M...
