Making Blobs with a Textile Mould 313 Fig.16.Model in DIANA Fig.17.3D scan of Blob oject large deflection of the system.But due to all the irregular bent surfaces there is no reference for the deflection.In this case a deflection of for example 400mm or 800mm cannot be seen.The structural system partly functions as a shell.At places where there is a transition from one curvature to another the outer forces are transferred by means of a bending moment.This is of course a bad situation for a thin walled structure.There are different solutions for this problem.From the solutions that were thought of the option of varying the wall thickness was chosen. Fig.18.Wall locally strengthened Fig.19.Wall locally strengthened in around problem area problem area 5.3 The Form-Active Analysis of the Structure The form of the indoor ski run was analyzed by means of describing the form by sections.To achieve the designed form there are a number of possibilities for the inflated structural elements that are put under the skin.At first the cross sections in width direction are shown.Next the different inflated structural elements are explained.Making Blobs with a Textile Mould 313 Fig. 16.
