The outstanding characteristics of structural efficiency, durability and aesthetic beauty make the thin shell structure a much more viable structural design solution as compared to the more traditional methods of design. However, the manifestation of these outstanding characteristics is directly related to the form of the structure. This makes the form of the structure a key factor in ensuring the success of the design. The correct form of the structure is not known in advance and requires a process known as form-finding or shape-finding. Hence, the focus of this research is to enhance this form-finding process, through the development of a computer design tool that is capable of accurately predicting the form of a pure compression thin shell structure, quickly and easily, in a manner that ensures that the desired characteristics are obtained within the structure. The analyses show that the computer model only corresponded to the shape of the physical chain model in two out of the six cases analyzed. The results suggest that the shapes produced by the computer model corresponded more closely to the shapes produced by the square slabs of yield-line analysis or the physical models developed using the hanging fabric modelling technique. In conclusion, the physical hanging chain models did not provide a correct representation of the shapes produced by the computer model.

The objective of this study is to elucidate as much as possible the theory and analysis of BOURDON tubes. Both thick-walled and thin-walled tubes are considered. Three papers, representative of the state-of-the-art of BOURDON tube analysis, are reviewed (References 1, 2, and 6): <p> 1. Wuest, W. "Theory of High-Pressure BOURDON Tubes". </p><p> 2. Andreeva, L. E>, "Elastic Elements of Instruments" </p> <p> 3. Dressler, R., "Elastic Shell-Theory Formulation for BOURDON Tubes" </p><p> Reanalysis of (3) above, with a different approach (Appendix A) checked and completed the general formulation by Dressler. The final forms of all necessary equations, boundary conditions, etc. to the solution of the three governing equations of the BOURDON tube with an elliptical cross-section are given. </p><p> Comparison of results of Andreeva's sensitivity equation with test data of Kardos, Mason and Exline (References 3, 4 and 5) using a qualitative approach as set out by Kardos (References 3 and 17) showed good correlation. </p><p> The study concludes with recommendations for the approach of future research and preliminary design procedures for BOURDON tubes. </p> / Thesis / Master of Engineering (ME)

In Australia, the standard structural system for residential construction is brick veneer where the stud wall (whether timber or cold-formed steel) is the load-bearing element and an external skin of brickwork is used for weatherproofing, insulation and aesthetic reasons. The stud wall framed structure has plasterboard interior cladding attached (commonly known as lining), brick-veneer exterior cladding, with terracotta or concrete roof tiles or steel sheet roofing. Therefore, the stud frame is lined on only one side with plasterboard material. This differs from the standard practice used in North America where both sides where both sides of the stud frame are usually lined, one with internal plasterboard material and the other with insulated external cladding material and a brick skin is not used. / Thesis (PhD)--University of South Australia, 2006.
