RESEARCH QUESTION

Is it possible to create a dynamic membrane system that can be actuated with shape memory alloy?

Geometry

Moom pavillion as inspiration for Tensegrity structures

The structural system replaces some of the linear elements of a tensegrity with tense surfaces and the collaboration between compressed bars and tensile fabric generates a freestanding translucent surface.

Fabrication of prototypes

After fabricating the Moom pavillion, the next step was to experiment with different geometries (placement of the rigid elements), so as to develop a new membrane system.

Finding similarities between Origami folds and the creazes of the prototyped tensegrity model, various geometries were tested.

These experiments failed as the fabric would fall flat, unable to form a 3d space or a structure. Hence, comparison to Moom pavillion led to analysis that the members should overlap creating staggered and continuous stress lines in the fabric to form a 3d space.

Based on these analyses, we devised other geometry patterns and tested them.

They worked!
