Asymptotic bamboo: a gridshell structure formed from coppiced bamboo in Belfast

This research explores innovative bamboo-based design through digital modelling, aiming to facilitate collaborative construction of complex structures in line with the Collective Intelligence Design theme. Students participated in building an asymptotic gridshell structure using untreated green bamboo canes, each unique. The methodology employs a student case study, teaching gridshellprinciples through hands-on exercises. Students collaborate during construction, exploring creative possibilities and assessing the role of digital modelling in co-designing complex bamboo structures, spanning the entire process from bamboo cultivation to structure completion. Locally sourced 4-6 m Pseudosasa japonica bamboo was harvested, dried, and tested for bending properties. The gridshell took shape using asymptotic curves derived from a minimal surface, with dynamic relaxation used to explore bamboo topologies and ground plane configurations for assembly. Despite material imperfections in using green bamboo, the gridshell assembled easily and formed the desired 3D shape. The workshop demonstrated the potential of collective intelligence, as students adapted to real-time observations, devised creative solutions, and shared knowledge to construct a gridshell using a locally sourced material. This research highlights bamboo’s creative potential and emphasizes the power of collaborative design and construction. It serves as a practical example offering insights into co-creation possibilities and interdisciplinary collaboration for addressing urban challenges, rethinking sustainable design approaches, and inspiring students for real-world applications, such as community gardens.
