This is due to the large tolerances in the built structures, which is caused by the variations in the dimensions and geometry ofnatural material as well as the manual, uninformed and imprecise assembly methods. In previous work, we introduced an adaptive fabrication method for bamboo structures that can monitor the fabrication process and compensate for deviations between built and designed form. As a proofofconcept, the method is suitable for small scale bamboo structures in 2D- or simple 3D configuration. This paper extends the previous method by integrating the adaptation strategies into a cohesive fabrication and assembly workflow for large scale complex bamboo structures. To enable that, a more effective sensor localization method, adaptation algorithm, connection and assembly system, as well as web-based user interface are developed. The effectiveness ofthe proposed methods is demonstrated through the fabrication of a pavilion scale branching bamboo structure that complies with intended geometric boundary conditions. Even though the material has substantial geometrical variations, the final structure shows small geometric deviations and a successful interface with the prefabricated roofelements. Our work shows how vernacular materials and processes can be digitally augmented in order to reliably produce building structures, hence enabling their usage in modern applications to a larger extent.", "file" : ":C\\:/Users/ac128044/Google Drive/ICD_Wagner/01_Publikationen/PUBLICATION_COLLECTION/2021_ECAADE_AUGMENTED_ACCURACY.pdf:pdf", "bibtexKey": "Qi2021" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/22ba835e442ba282ea3807a60fbc66ee2/intcdc", "tags" : [ "myown","digital","material","rp3","fabrication","placement","fibre","itech","dimensional","joints","from:hansjakobwagner","robotic","lightweight","three","systems","design","tectonics","peer","structures","reinforcement","timber","fibrous","wood","computational" ], "intraHash" : "2ba835e442ba282ea3807a60fbc66ee2", "interHash" : "8d171bda41464565a14ce37b2fa6e9f2", "label" : "Three-Dimensional Fibre Placement in Wood for connections and reinforcements in timber structures", "user" : "intcdc", "description" : "", "date" : "2021-09-15 14:27:26", "changeDate" : "2023-01-20 17:46:11", "count" : 4, "pub-type": "inproceedings", "booktitle": "Proceedings of the IASS Annual Symposium 2020/21 and the 7th International Conference on Spatial Structures", "year": "2021", "url": "", "author": [ "Hans Jakob Wagner","Dominga Garufi","Tobias Schwinn","Dylan Marx Wood","Achim Menges" ], "authors": [ {"first" : "Hans Jakob", "last" : "Wagner"}, {"first" : "Dominga", "last" : "Garufi"}, {"first" : "Tobias", "last" : "Schwinn"}, {"first" : "Dylan Marx", "last" : "Wood"}, {"first" : "Achim", "last" : "Menges"} ], "editor": [ "S.A.

Although natural fibres can be used for such technique, the presented work focuses on CFRP tows - that have a special advantage as they can be cured via electrical current in-place without oven or autoclave while the wood material acts both as insulator and formwork. The three-dimensional geometries of the discussed fibrous arrangements are hardly limited in their form which makes precise computational design strategies the cornerstone for an effective exploration, understanding and exploitation of the design potentials of such structures. We show how principal local stress-directions, fabrication specifications as well as design- and environmental considerations can be considered to form-find meaningful fibrous layouts within such structures. The proposed technique most notably creates novel performance-spectrums for sustainable, ultra-lightweight bespoke wood architecture by enabling tailor- made bending resistant on-site connections, that break free from added weight, expense and the intensive energy footprint of steel connectors. We further discuss our investigations within this framework through the prototypical fabrication of physical demonstrators that represent a comprehensive set of wood building system typologies: custom fibre-reinforced slab plates, a segmented plate shell structure and a polygonal lattice shell structure.", "venue" : "Guilford (UK)", "file" : ":C\\:/Users/ac128044/Google Drive/ICD_Wagner/01_Publikationen/1809_FIBRE_TIMBER/2107_IASS_Surrey/Paper Submission/IASS_3D_Fibre_Placement_in_Wood.pdf:pdf", "bibtexKey": "Wagner2021" } ] }
