AC 2014 – Polymer Folding Scapes

The project represents a continuation of research that explores the potential of polymer concrete applications and wood/concrete composites in the production of full scale structures. It is a collaboration between the Institute of Architecture at the University of Applied Arts Vienna and the Hochschule Trier.

The handling of virtual simulation methods and the engineering of full-scale structures using digital manufacturing were a pri­mary focus of the project. A hyperboloid surface was designed in Rhino Grasshopper and optimized using Karamba and multicriteria optimization in Octopus taking into account the architectural site context, structural behavior, assembly and construction limits.

The formwork was unfolded from the 3D model and laser cut on polystyrol sheets. The wood members were fit at the joints in the formwork and the polymer concrete was cast. After the curing process, a stiff wooden joint consisting of direct adhesion of wood and concrete was achieved. The overall geometry emerged through the precise folding process of the cast nodes.

A Grasshopper definition was developed to extract two types of nodes, the cast 3-points polymer concrete nodes and wood – wood connection joints between the 3-points modules. Grasshopper was used to compute the wood – wood joints at a right angle to allow for easy assembly and fixation while erecting the final structure.
