The Neville Bonner Bridge, spanning the Brisbane River, features a unique combination of cable-stayed and arch structural forms. The bridge deck is suspended from cables tied to the top of both the arch section and the cantilevered mast, creating a visually striking and structurally efficient design. The tied arch spans 138 m, while the cable-stay section stretches 145 m, and a single approach span of 37 m completes the bridge’s total length of 320 m.
The bridge deck, measuring 4.5 m between railings, is a composite structure, consisting of two steel I girders that support the cross-spanning concrete deck.
The bridge design verification and analysis were conducted using SOFiSTiK software, covering a comprehensive range of structural evaluations. These included TH3 construction stage analysis, cable force optimization, camber analysis, cable rupture analysis, TH3 transient load analysis, pedestrian footfall analysis, and wind dynamic analysis.
