Conclusion During the Structure Calculations the break-free course of the “rods”, especially in the edge regions was an essential criterion. Where breaks did occur, they were eliminated by automatically displacing the edge point or by intentionally changing the lengths of the rods. The shape of the shell was established by photogrammetric measurement of a hanging chain model and is funicular. A continuous shell made from an isotropic sheet material has equal properties in all directions Diagonal stiffness can be introduced in various ways. By making the joints rigid so that shear forces are carried by bending moments around the element ring.
The lattice shell system can be thought of a construction technique which is related to the form finding process of using hanging chain nets. The structure stiffness was added whit double layer shells, is added by tightening the node bolts so that the two layers act compositely and by i]nstalling the ties. The adjusting of the grid in its final position was made before the edges and knot points were fixed by bracing from the below with “airsupports”, to eliminate sagging of the grid between the scaffolding towers.
