Sydney Opera House - A1 Shell Interior model
Each main shell of the Sydney Opera House consists of a series of ribs. The centreline of each rib is equally spaced at 3.65 degrees, with the centreline of each rib passing through the pole of the 75m radii sphere they are designed on, meaning the ribs can spring from a universal point, allowing them to extend or shorten using only one mould. The mould was built at the longest required length and then walled at 4.6m lengths to make the different ribs required for each shell. Each 4.6m segment had a maximum weight of approximately 10 tons.
Based on an elevation construction drawing for the Sydney Opera House, this model shows the detail of these concrete ribs as viewed from inside the building. Of note is the cast concrete pedestal, that received each one of the ribs and provided the base for the tensioning cables that would provide stability for the rib segments.
-
The sculpture is made from eco-friendly resin-plaster. All materials are sourced locally, made 100% in Sydney. Each model is framed using sustainably-sourced Australian Victorian Ash.Size: 30x30x4.5cm frame
Total Weight: Approximately 1.5kg
Each model is hand-cast with its own small deviations in colour and texture and small air imperfections within the casting.
