Cellular Cavity Structure and its Building Technology for Shell Structure with Thin Sheet Materials-- Geometrical Analysis and Structural Consideration in the Design and Building Processes.
Technische Universität Darmstadt
Dissertation, Erstveröffentlichung
Kurzbeschreibung (Abstract)
This research investigates a new structure concept and its building techniques for shell structures that can be built with thin sheet materials. Shell structures have been a desired structure type for both architects and structural engineers due to its efficient load-bearing behavior and also the elegant curved geometry. In the past decades, innovational structure concepts such as grid-shells and spatial framework structures have continuously pushed the development of shell structures towards a comprehensive type of structures which provides a better structural behavior of building materials. This dissertation argues for a material-driven design methodology of the new shell structure design through a well-rounded revisit of the development of shells in the past decades. And a new type of industrial materials has been selected for the innovational structure concept of the novel type of shells. The research is based on a comprehensive analysis of the materials’ application in the existing industrial and architectural design, as well as the theoretical analysis of the materials’ behavior and the corresponding fabrication techniques and structural consideration in designs. A novel structure concept is then generated with also the inspiration of the natural cellular structures. The main focus of the architectural analysis is the design procedure of the cellular cavity structure, including the form-finding process, the structural consideration of the stability problem of thin materials, the possible simple fabrication with the materials form a planar sheet form. At the same time, a collaborative design process is also discussed to enable a better cooperation between both architects and engineers. A novel shell was finally built as a demonstrator of such a structure concept. With a dome which reaches a span of 5 meters and a height of 2.5 meters and was built only with 1mm paperboard as major materials, the load-bearing capacity and the construction details of the cellular cavity structure is tested and evaluated. Finally, through the comparison with the recent parallel research and the popular experimental shell designs in the past several years, the cellular cavity structure is positioned into a series of relevant research fields. With the analysis of the limitations of this research, future works are also defined for the improvement and future development of this Ph.D. research.
