State of The Art

• It is the first pedestrian river crossing over the Thames in central London for more than a century

• A piece of public architecture which made it on to the ‘A list’ of London attractions

• Pure engineering - forms and material are derived from their structural purpose creating a simplified, modern construction with a horizontal emphasis

 

The Design

• 1996 the Financial Times held an international competition with the London Borough of Southwark and the Royal Institute of British Architects

The vision was a long span bridge with a pure expression of the structure, it should be the link between Tate Modern Gallery and St. Paul's Cathedral; pure sense of physical form that drives the sculpture, and a minimal design that gives pedestrians unrivalled views of London, free from traffic and high above the Thames

• After an happy swaying opening celebration in June 2000 with more than 80,000 visitors crossing the bridge and seasick walkers as well as random swinging and swaying the bridge was closed by the engineers

• The funny side was that the engineers announced that the walking was the reason for the movement

• It did not take long and the bridge was renamed ‘The Wobbly Bridge’

Eventually the bridge did not full fill its purpose and since they could not stop people walking across the bridge in a certain way they decided to install two forms of passive damping

• Viscous dampers around the pier, under the deck and the south landing to control the lateral motions that act much like shock absorbers

• Tuned mass dampers are located beneath the deck to reduce vertical movements like weights on a strings

• After nearly two years of testing, hundreds of paid volunteers walking over the bridge, the bridge was finally reopened to the public in 2002

The Architect

• Foster + Partner

• Sir Anthony Caro [Sculptor] and Ove Arup & Partner [Co-Architect]
