The effect of fishing basin construction on the behaviour of a footbrdge over the port channel
PublicationThe paper analyses possible causes of failure of the rotating footbridge over the Ustka port channel. In July, 2015, strange behaviour of this object was observed in the form of excessive vibrations of bridge platform suspension rods, with the accompanying acoustic effects. A preliminary geotechnical analysis has revealed that this destructive effect was caused by the nearby construction works, namely construction of a fishing...

Structural Health Monitoring System for Suspension Footbridge
PublicationThe article presents the structural health monitoring (SHM) system installed in a footbridge in Radom. The main reason for the need for fitting of such a system was failed acceptance tests of the bridge. While under a dynamic load consisting of a group of 12 pedestrians jumping on the bridge, the bridge developed vibration during which acceleration of the deck of up to 4.5 m/s2 was recorded. Such behavior of the footbridge causes...
