| summary |
Timber, as a building material with carbon sequestration ability, has significant potential in promoting sustainable development goals. Advancements in parametric design and robotic fabrication are revitalizing traditional timber craftsmanship, leading to a new era of non-standardized design a mass customization.
Modern timber structure construction faces key challenges, including analyzing traditional mortise and tenon joints' structural performance and seamlessly integrating parametric designs into robotic workflows. Achieving effective modeling for these joints requires a specialized, intelligent toolkit that spans the entire design-to-fabrication process, tailored for robotic fabrication. The study focuses on the "Mortise and Tenon Beam-to-Beam" technique, combining traditional methods with advanced technology through the FUROBOT-based "Mortise and Tenon Beam-to-Beam Joints Solver." This innovative toolkit, applied in designing and constructing a timber pavilion, enables large-scale, flexible customization in timber structures.
The research begins with a detailed description of the generation of parametric joints. Following this, to enhance joint performance, finite element analysis is conducted in Abaqus, focusing on the anisotropic nature of wood joints. This analysis feedback is used in conjunction with the solver to compare multiple solutions and obtain the best high-performance joint solution. Subsequently, robot tool path generation and trajectory optimization are undertaken, considering the constructability of the wood.
In the practical application phase, a timber pavilion spanning 682 square meters and standing 6 meters tall, constructed from 603 glued wood components, was erected. The empirical demonstration of the "Mortise and Tenon Beam-to-Beam Joints Solver" process verified its effectiveness and efficiency in enabling architects to design high-performance joints and implement robotic fabrication workflows. The total processing time for the 603 glued timber components was 30 days, marking a 1/3 reduction in time compared to traditional timber structure workflows. This achievement underscores the toolkit's role as a driving force in advancing non-standardized design and promoting large-scale, flexible customization in timber structure construction. |
