The two prototypes comes out of the fascination of bending materials.  Looking at the properties of for example plywood, it is possible to fold and bend a flat plane  into a 3-dimensional structure.  We have made several experiment with different bending patterns in paper, cardboard and plastic to try to understand the different opportunities and limits within the bending.

When the plane is cut and corners of each cut is joined, the plane converts into an arch. Structure01-concept PROTOTYPE 01: BUILDING THE STRUCTURE By having a bending in two different directions, gives a stiffness to structure. The bending in two directions is achieved by cutting crosses in the material and folding the edges in two different directions (see drawing below). Structure01-building PROTOTYPE 01: FORCES IN THE STRUCTURE The construction is made out of minor folding arches in two directions. In combination they create one big arch.  The whole structure works as one arch. The whole arch, as a concept, works with tension in the outer core and compression in the inside core of the arch. The arch is made out of several arches, which is working in two directions. By bending the material, the forces are transferred throughout the construction – from one arch to the other. Structure01-forces3   USING INFLATION TO CHANGE THE STRUCTURAL BEHAVIOR The next evoultion of the structure is how the shape of the construction could change by inflation air into the structure. We made different experiment with different materials and constructions, which all included folding elements. The final test proved that we were able with a ballon to convert a flat structure into a vertical structure by inflating a ballon inside the bottom of the construction.
