Abstract

The paper presents a system, made out of a foldable frame and a membrane skin. The concept refers to origami. The following research question is considered: can the foldable canopy be a stable roof in intermediate configurations? Several numerical models have been made. Finally a dome-like prototype has been designed for which an integrated numerical model has been analysed. The membrane is represented by a cable net, the frame by beam and bar-elements. The membrane is only attached in the nodes of the frame. One part of the canopy remains fixed, the remaining part can be folded while the nodes at ground level remain at level 0.
For the skin a silicone coated polyester fabric has been chosen. It is modelled as an assembly of flat triangles, tensioned into the frame by belts. The anticlastic curvature is obtained by transforming the flat quadrangular meshes into space. To obtain a well tensioned membrane in the intermediate positions the belts connecting the membrane to the frame can be released or increased in tension. This can be simulated by setting the force densities.
Since the membrane has been modelled as a cable net, without shear stiffness, the obtained numerical results are approximate. A real size dome will be built to measure the tensions and evaluate the transformations.
