Case Study
Wellington Street Swing Bridge
- Assessment of historic cast iron
swing bridge
- Development and analysis of
strengthening options prior to refurbishment
Wellington
Street Swing Bridge is a historic 18th century, listed, cast iron
bridge that spans a lock basin between the Humber estuary and Hull
Marina in the UK. The bridge had fallen into dis-repair over the years
so, in 1999, Pell Frischmann was commisioned by Hull City Council to
carry out an inspection of the bridge and to provide an assessment of
its strength.
Then, in 2004, another
commission
was given to
Pell Frischmann to
investigate the feasibility of bringing the bridge back into use and
to develop refurbishment options.
Pell Frischmann used LUSAS
Bridge analysis software to create 3D models to assist with its analysis of various strengthening
options that led,.ultimately, to the bridge being re-furbished,
strengthened, and brought back into full working order for use by
pedestrian, cycle and occasional vehicle use for vehicles up to 7.5
tonnes in weight.
In Davy
Markham's rehabilitation of this two leaf Victorian swing bridge, new
electric slewing drives were also added to replace an earlier attempt at
electrification and utilises, as much as possible, the existing
gear train left from the days of a hand-wound system.
