Spanda

Details

ShapeShift Technologies worked with artist Christian de Vietri from the inception of the Spanda project, initially providing the required feasibility study and backing for his artwork submission as the major works of the Elizabeth Quay upgrade.  Spanda is a series of six aligned nested rings that vary exponentially in size about a central point, each tapering as it reaches the sky. The largest of the rings is 29m high. Following Christian’s success in his proposal, ShapeShift Tech completed all the design, engineering, project management, manufacture, installation and certification of the large Spanda artwork.

Given the size and cantilever of the structure, a detailed engineering analysis was required. The engineering analysis utilised finite element analysis to determine static performance and normal modes of the structure.

In addition, a detailed analytical and finite element analysis was conducted to review the structures response to vortex-shedding phenomenon. To ensure the structure met performance specifications, a high-strength ShapeShell-RT was required and developed through use of analytical calculations and physical testing. The resulting material was tested to a UTS of 660MPa. We also collaborated with civil engineers to design the foundation and completed internally all the engineering of the connections into the foundation.

To install the units within the site constraints, it was required to lift each of the rings as one entire unit. This meant the largest lift was a ring unit of almost 30m high and 6m across. This lift was completed in a similar manner to the stepping of a mast. All the design and engineering required to prove this out was also completed in-house.
