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