Alfred Wunder Buildung of the IL in the Pfaffenwald drawn by Tobias Burkhardt (9 vears old) The study of the form and structural behaviour of historical vaults and domes has been continued. Since the reconstruction of Gaudi's wellknown sus- pension model (about 1900) for the church in the housing estate Giell (Rainer Graefe / IL, Jos Tom- low / Gaudi Group TH Delft, Arnold Walz) and the re- construction of the hanging models (about 1830) used by Heinrich Hiibsch for his church designs (Rainer Graefe, Arnold Walz) the structural behaviour of the Pantheon in Rome (approx. 120 A. D.) has been investigated by students with similar model tests. Currently the optimal form of cross-vaults is the subject of further model tests. BUCKL ING Buckling tests provided information about the pro- cesses of deformation of forms of different materials. Systematic pressure measurement during the evacuation of technical pneus (rubber balls) showed varying stability at different stages of evacuation. The observation of organic objects (skin, guts, ber- ries, fruits) with regard to deformation and surface creasing during the ageing processes provided a basis of analogy. The surface textures of pollen result from drying or reduction of internal pressure. A students work documents these deformations in natu- ral and technical objects. PNEUS As part of the investigation of natural and technical pneumatic structures loading tests (increased inter- nal pressure, axial loading and bending) were used to examine the behaviour of natural pneus (berries, guts) and mono- and multicelled technical pneus fair-filled paper columns and water-filled tubec) TENTS Using soap film and tulle models a preliminary typo- logy of ridged tents has been developed. In two stu- dent studies the essential parameters of form for monopost tents with two or three ridges were demon- strated by numerous tulle models which differed with regard to their marginal conditions. Jiirgen Bra- datsch's diploma study enquires into the use of un- dulating forms for large circus and festival tents (ref. 111. on top). Using the two test frames which have been developed at the IL various membranes of different properties were tested with regard to their durability under complex tension conditions. Thus realistic assump- tions for the corrections of the cutting pattern of tents and pneus could be deduced. FOLDS The auto-generation of form through folding has been scarcely investigated. Preliminary model tests aimed at answering the follow questions: variety and form of characteristic folding patterns. Which conditions lead to which patterns? How can the patterns be com- bined? Is it possible to deduce the original condi- tions from the form of folding? Tests using different materials, for example rubber sheets or cloth in horizontal and vertical position, show that the diverse folding patterns - even in com- bination - result from only a few basis forms. Further model tests are planned to investigate the structural possibilities of self-generating folds. Further, discoveries in the field of both, living and non living nature, are expected to be gained from a more precise knowledge of folded configurations & Ih [1 INFO 2% { 198K"
