Providing a missing link in Melbourne’s sports infrastructure, this new stadium
in Australia will be a world-class sporting event and administration complex,
featuring a sports campus, elite training center, and sports administration
area. The new stadium will accommodate 31,000 fans for soccer, rugby league,
and rugby union matches. The stadium will have a cutting-edge bioframe – a
lightweight steel design based on the inherent structural efficiencies of the
dome – with a geodesic roof that will substantially cover the seating area
while letting in maximum sunlight. This design will use 50 percent less steel
than a typical stadium roof of the same size.
The project team needed a tool to undertake optimization studies on the roof
steelwork sizes and geometric configurations as well as to efficiently cope
with any changes to the roof geometry during the design process. Arup also
wanted to produce a set of tender documents that provided contractors with
the size and length of all of the individual steelwork members in the roof.
GenerativeComponents was identified as the best solution for modeling
Using GenerativeComponents, Arup created a centerline wireframe model of
the structural roof, which was then used by the structural design engineers
for analysis. Data exported from the GenerativeComponents model was
used for optimization studies of the roof steelwork for each configuration.
The final analysis model was imported into Bentley Structural for completion
of the 3D model incorporating the final steelwork member sizes. Producing
this revolutionary design would not have been feasible without the ability to
quickly regenerate different geometric configurations and export the data in a
format that could be linked to the analysis software.
