| summary |
Buildings with complex shapes are increasingly being constructed using digital fabrication tools. However, many building components nevertheless require specialised skills for their assembly at the construction site, even if the manufacturing has been streamlined. In this study, by practising an agile design process that repeats the method of ‘Add-on the tool’ and ‘feedback on form and material, we devised a construction method that allows unskilled workers to be involved in the fabrication of pavilions and the creation of complex curved surfaces without requiring special skills, so long as the rules of assembly are determined. In this study, a method of achieving large curvatures using wire bending of Y-shaped wooden units made of 4-mm thick lauan veneer boards was proposed, in which large curvatures were used to design two-dimensionally curved surfaces with continuous wavy shapes. This method was also used to control the force applied to the wires by controlling their lengths. The free curved surface with the elastic bending of the plywood allowed a height of 2.3 m and a span of 6 m. |
