Structural health monitoring on the Queensferry Crossing: the most sensored bridge in the world

14:00 - 14:25

Scotland’s landmark structure opened in 2017, breaking world records including at 2,187 physical sensors the world’s largest structural health monitoring system on any bridge. In this presentation, we present a summary of the system installed, its uses to date and further intentions. A load test involving six heavy vehicles was conducted to verify the monitoring and bridge performance. Lessons learnt for future applications are shared.
