Tank Street Bridge is getting a lot of attention as the first large scale tensegrity bridge. The bridge is currently under construction in Brisbane’s inner city. Brisbane is one of today’s fastest growing urban centers in Australia and the bridge is part of the City Centre Master Plan 2006 anticipating an increasing demand for pedestrian areas. It will link the city center to South Brisbane: from Tank Street to Kurilpa Park traversing Brisbane’s navigable river. The construction of the Tank Street Bridge is expected to be completed by September 2009 so that it can be part of Queensland’s 150th year anniversary celebrations.
Tensegrity structures belong to a special category of cable structures. They are defined as systems composed of compression components (struts) inside of a continuum of tension components (cables) in a stable self-stressed state (equilibrium). They are lightweight structures offering higher resistance than other systems of the same weight. Another advantage is their modularity; stable modules can be joined together creating larger tensegrity systems.
From an engineering point of view, the construction of the Tank Street Bridge is a civil engineering achievement. Tensegrity structures are highly complex systems with non-linear behavior. Therefore, the analysis of these structures demands complex computational methods. Additionally, previous tensegrity constructions such as the Rostock tower (Germany) revealed a necessity for high precision. It is also important to mention that there are no widely accepted guidelines for the construction of this kind of structures.
The resulting tensegrity bridge is a network of cables held apart by numerous struts recalling the ropes and spars of sailing ships and boats. Seen from the rivers, struts seem to float over the bridge. They remind sculptures made by the American artist Kenneth Snelson (see “Easy Landing”). Additionally, due to its tensegrity system the bridge offers high transparency with great views over the river to pedestrians. During the night, the bridge will be full of colors. LED lights are chosen to highlight the masts with pastel colors creating a levitating illusion for pedestrians. Different colors will be applied based on the chosen theme creating a contemporary sensation.
About time a nice bridge crossing the Brisbane River!
All others are old and out-dated. This should liven up the river, epecially at night by the looks of things.. nice.
it’s a bridge made to be looked at from far off distances and post cards.
The renders are very striking, but the bridge itself so far looks so much larger and a lot less elegant…hopefully it all comes together nicely and proves me wrong.
And just for reference, Baulderstone Hornibrook Queensland are actually the builders/project managers.
Not cool
ZZZZZZZ. There were better options than this! Pick up stick style architecture is not elegant
Made to take postcard shots from, not to be included in.
I love engineers too
This engineering marvel should be named “Crow’s nest Bridge”.
Awful (at least now, under construction), obscures the views and creates an untidy, busy look in the already busy city!
I think that it looks great, Brisbane needs more architecturally significant buildings.
I think it is ugly and will always have an unfinished’ look.
Does any one know how people using the bridge get on to the pedestrian/bike path by the river if they then want to continue walking to Toowong?
Looks fantastic, will do a lot for the CBD.
The unpleasant ‘cage-like’ structure that the bridge now incorporates over the Riverside Expressway was not necessary. The bridge approaches now resemble a high-security prison walkway. Was the cage structure incorporated to remove the temptation for punters to throw items onto the Riverside Expressway? If this is the case – why not cage the Victoria Bridge too!!
The cage has made an otherwise ‘lightweight’ and ‘transparent’, almost ‘floating’ form of construction look bulky and distasteful. What a shame – so much potential!!!
Love it!
Evokes images of tall ships back in the 1800s when they probably sailed up the Brisbane River to offload their cargo in South Brisbane.
A nod to the white settlers, and naming it Kurilpa acknowledges West End – a double gesture!
