Abstract:
The Eleanor Schonell Bridge (previous/working name ‘Green Bridge’) is Australia’s first dedicated pedestrian, cyclist and bus bridge, and connects University of Queensland to Dutton Park across the Brisbane River. This paper discusses the broad environmental considerations in conception and construction. Also discussed is the cable stay system features, governing standards, specifications, interaction with the bridge deck, bridge towers and construction of the deck, and the other main components of the bridge. Design and detailing of the cable stays, stay cable testing and acceptance, characteristics of wedge anchored prestressing strand cable stay systems, durability, resistance to wind and rain induced vibration, provision for individual strand restressing, destressing and replacement, inspection and monitoring are also discussed. Construction aspects discussed include procurement, construction method and program, tower and deck access methods, strand by strand reeving, stages of stressing of stays, and allowance for future restressing for light rail overlay. Architectural aspects discussed include the geometrical arrangement, range of colours and finishes available for stay pipes, architectural treatment of anchorages and vandalism resistance.
