Lighting up Simonds Stadium
Modelling has optimised the light towers installed at Simonds Stadium in Geelong to allow the TV broadcasting of night football and cricket matches at the stadium.
Light towers have been installed at Simonds Stadium in Geelong, the home ground of the Geelong Football Club. Aurecon was engaged by the architect, Populous, to engineer light towers that will allow the TV broadcasting of night football and cricket matches at the stadium. The detailed sports lighting design was undertaken by the floodlighting luminaire supplier, Sylvania. Aurecon undertook concept design sports light modelling, wind tunnel testing and a three-dimensional finite element structural analysis for the project.
The towers were formed as a tubular structure similar to wind turbines in order to suit wind turbine manufacturing processes. Contrary to standard wind turbine structures, the tube was bifurcated near the top in order to form the frame for the lights.
The tower tubes were modelled using the three-dimensional finite element software Strand7 and optimised to reduce the tube wall thickness to minimise the overall steel weight and cost of the structure. The solution underwent extensive wind tunnel testing to ensure the dynamic response to wind was acceptable. A building maintenance unit lift was installed to enable maintenance staff to access the head frame.
