Whether individually or summed up, the petals of these self-standing structures provide roofing and spatial organization to the activities and actors below.
Form is driven by material properties and geometrical topology. In actively bent elements the curved end-geometry is achieved by elastic bending where stress-distribution is not constant. Local stress maxima restrict the design-load of the whole structure. Restraining systems can be used to optimise the shape of the elastically bent elements to get a continuous curvature and therefore a homogeneous stress-distribution. In addition they improve the stiffness of the overall hybrid system significantly. Besides the structural enhancement, restraining systems offer a wider range of shapes than the strict “elastica” curve.
