JF Strainstall has devised a number of techniques for identifying and managing hidden defects in moveable bridges.
See our mini case studies below or contact our team to discuss your structural monitoring requirements,
M5 / M6 Midlands links
Hidden defect: Un-inspectable details
Problem: Data relating to bearing behaviour was required to plan maintenance work on multiple motorway links.
Solution: JF Strainstall set up monitoring at four separate locations on the Midlands links in order to gather information about the actual behaviour of bearings and supporting structures, facilitating maintenance planning.
Somerleyton / Reedham
Hidden defect: Articulation and load bearing issues
Problem: General structural performance.
Solution: Monitoring was implemented in order to identify how the bridge was operating and where the load paths were under trafficking.
