This spectacular 31,000-seat rectangular stadium is the result of collaboration between Arup and Cox Architects. It features an innovative bio-frame roof creating a highly efficient, functional and visually exciting structure.  Designed by the application of shell theory and 3D modeling tools, the roof is made up of 20 interdependent shells and a single layer of structure that shares the load through a combination of arching, cantilever and shell action. The resulting structure is considerably lighter and uses around 50% less steel than traditional structural solutions.

 

Arup’s use of 3D modeling and computer technology, some developed in-house, drastically streamlined the design process. This included using Generative Component (GC) software to prepare parametric models to define the roof structure, allow for testing of alternative geometric configurations, creating wireframe models, and preseting the final geometry for fabrication and construction.

 

The structural design team used in-house optimization software together with Strand7 analysis software to study the structural efficiency of the roof. By optimizing the member sizes, the most efficient structure was determined, resulting in considerable savings in the amount of steel required for construction. The shell and other concrete works were fully realized in 3D from concept to construction.

 

AAMI Park's roof maximizes natural light and ventilation for both spectators and the health of the playing surface. The bio-frame provides 80% coverage for spectators, insulation and integration with a drainage system that collects rainwater.

 

Arup provided structural and civil engineering, turf and pitch consultancy, façade and pedestrian modeling.  The unique triangulated single-layer roof represents the next generation of structurally efficient design. It allows forces to flow in three directions and was inspired by principles of shell theory and the famous geodesic domes of Buckminster Fuller.
