• The purpose of this cable structure is to give stability and resistance to bending to a pipe which runs in the middle from one end to the other end of the structure. It is achieved by a spiral cable bracing bearing on compression hoops connected to the pipe core by radial ties. (Even though I design tension structures, with a little trick, compression can be used in the design, as you see.)

• This is a membrane structure covering a concert hall. It was one of my first designs. More information about the design process can be found.

• The truss "super-structure" and the membrane were handled together during form-finding. The design would have been easier if they had been handled separately, but it was a challenge.

• This picture shows a hexagon shaped structure before the form-finding

• And this is the final form. The middle point is not fixed and raised by the structure itself during the form-finding

• This is a tension structure modeling a medieval vault

• This is the color version of the medieval vault. The model contains more than 7000 elements.

• A wireframe version of a hyperbolic surface. The cables give the "driving force" during the form-finding while the membrane pieces can be imagined as stretched between the cables.

• It shows the initial form of the hyperbolic surface. Unfortunately the cables are not visible here.

• And this is the form of the hyperbolic surface in color.

• And finally (for now), this is a square piece of cloth under pneumatic pressure. Well, quite a lot of pressure
