Project Update

Initially, research focused on creating a theoretical framework for anticlastic wild cane structures. Paul Oliver study of vernacular archetypes contributed to identifying a relationship with elastic static systems and flexible materials. The relationship within form-active lightweight structural systems utilised the Institute of Lightweight Structures work on Bamboo, where the term ‘curved compression rod construction’ describes these types of anticlastic structures.

A variety of case studies of reinforced concrete shell structures built with a combination of two different lightweight systems were analysed, with a focus on the secondary system that function as a permanent or temporary formwork.  Design criteria were established on the basis of those results, which determined the construction of hybrid shell structure in Colombia using wild cane and cementitious materials -canecrete-.

Suitability of wild cane as an active bending material was corroborated graphically and mathematically with data obtained from previous research. Elastic deformation used as a self-forming process can be approached by three ways: behaviour-based, a geometry based and an integral approach, Lienhard (2013). A behaviour-based approach describes vernacular methods of construction with wild cane. However, this research is focused on a geometry-based approach where geometry is defined by analytical or experimental form-finding methods. Currently experimental work with wild cane arches searches for a feasible spatial configuration with optimal behaviour under compression stresses.
