Adelaide Festival Bridge: ribbon of light

The Adelaide Festival Bridge is a lightweight cable stayed pedestrian bridge spanning 41 metres, providing a pivotal north-south link between the City Centre and the banks of the River Torrens. This bridge has been designed to be a landmark bridge for Adelaide and South Australia. Its unique glass floor, when lit at night gives an impression that pedestrians are walking on a ribbon of light. The bridge itself consists of Vierendeel trusses that act as the balustrade, and supports the grillage of beams that in turn support the unique glass floor capable of carrying a 5kPa uniformly distributed load or a 5kN point load even when damaged. The infill to the balustrades also consists of glass. The Vierendeel trusses are supported by an array of stainless steel cables tied to an asymmetrical cantilevered tapered forked mast. A great deal of testing was carried out on both components of the structure and the finished bridge in order to verify assumptions made in the design of this unusual structure. This paper will summarise some of the more interesting features of the design and the testing related to the dynamic performance and behaviour of the glass deck.
