Abstract: The thesis seeks to enhance the flexibility of fabricating and constructing timber plate structures with Planar Hex form for a double curvature surface. It focuses on solving connection(s) to develop a radical strategy to synthesize Timber plate structure with Planar Hex, such that it could be applied to any double curvature surface efficiently, to built a self-stable structure. Therefore, a systematic process has been followed to attain this connection design, which in combination of material and form enhancements allows for increase in reliability and precision of the assembly of this geometry easily on site. In order to achieve the desired connection design, physical & digital means of form-finding, analysis and fabrication techniques are used. This strategy proves that Planar Hex structures with this connection detail can be assembled on site rapidly with no reliability on high-tech machines and robotic technology and can be done using practical medium cost technology.
Hypothesis: “Develop a radical strategy to solve connection(s) in order to synthesize TPS with PHex, such that it could be applied to any double curvature surface efficiently, to built a self-stable structure“.
Connection Design: Strategy to find the right connection; Finding Solutions – types of connections; Physical Experimentation – Testing on 3 adjacent plates: Experiments conducted to study type of connection, Joint systems – box systems/puzzle, Steel connections.
Form Finding & Optimization for Phex Surface: Digital experimentation for a double curvature surface; Planar Clustering (topology behavior); Structural Analysis – Experiments conducted for various cross-sections and thickness – option 01/ option 02, Analysis results; Permutation & Combination for choosing the optimum connection for fabrication.
Fabrication of Timber Plate Structure: Digital experimentation for the PHex surface – Testing on 3 adjacent plates; Solving Connection Detail – Prototype Production for 3 adjacent plates:
- Joint Geometry Generation – timber; steel; insulation
- Connection Generation – timber; steel
- Fabrication process – timber; steel
- Finished prototype
Conclusion: The connection detail is easy to cut, fabricate and assemble on site. Therefore, it increases the flexibility to grow it on a larger scale. This strategy of solving connections and assembly on site is one of the ways to synthesize timber plate structures with planar hex, such that the strategy could be applied to any double curvature surface efficiently, to build a self-stable structure.
