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.

Fatigue


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.
