The Kangaroo Point Green Bridge, which spans the Brisbane River in Australia, has a total length of 460 meters (including approach spans), with a main span of 183 meters and a side span of 90 meters.
The bridge’s distinctive 91-meter-high pylon features a single column base with four cradling legs that envelop the deck and converge at the top, creating a striking architectural element. The deck is a steel-concrete composite box girder, measuring 6.8 meters wide between the kerbs. The pylon substructure below the deck level is constructed of concrete, while the superstructure above the deck is made of steel.
The bridge analysis was carried out using SOFiSTiK software, encompassing a range of sophisticated evaluations. These included TH3 construction stage analysis, cable force finding, camber analysis, cable rupture analysis, TH3 transient load analysis, pedestrian footfall analysis, and wind dynamic analysis. Additionally, geometry control analysis was conducted during the bridge’s construction to ensure precise structural alignment and performance.
