York Society of Engineers Lecture

Forth Road Bridge: Truss End Link replacement

The Forth Road Bridge is a long span suspension bridge that crosses the Forth Estuary near Edinburgh, Scotland. It was opened in 1964 and at the time was the fourth longest suspension bridge in the world, outside America, with a total span of 2.5km and a tower to tower distance of 1,006m. In 2015 a fracture was found on the North East main span link that supports the bridge deck adjacent to the tower. This link connects the bottom of the truss end to the tower via pinned connections that allow the bridge to move along its length. 

This talk will discuss how this was rectified, the challenges that were faced during remedial works and how these were overcome. Focusing on how the trussed deck was temporarily supported and then repaired, including the temporary works that were required to access each location under the deck, 45m above the estuary.


Humber Bridge: Dehumidification of long span bridge suspension cables

Corrosion inside the main cables of suspension bridges can have huge effects on the integrity of the cables and subsequently the life span of the bridge. Retrofitting a dehumidification system to these cables has prevented further corrosion and helped prolong the lifespan of bridges.

This talk will all discuss all aspects of a cable dehumidification on long span bridges including how the dehumidification system is installed and how it works to prevent cable corrosion. This will also include the innovative approach used to access the main cable to carry out these works.

Tea and coffee from 7pm.
