WOVEN WOOD: designing for material performance WORKSHOP WITH METTE RAMSGARD THOMSEN / MARTIN TAMKE / TORE BANKE /KARIN BECH CITA THE RED HOUSE / THURSDAY 19 – 27 2009
Test models at CITA
Digital fabrication introduces new links between design, manufacture and craft. As design becomes increasingly informed by computation we enter a practice that can engage with increased levels of complexity. In this workshop we will explore the intersection between digital design strategies and designing for material performance. Working with woven wood structures we will investigate how self-bracing wood structure can lead to new structural systems. We will work with parametric digital design tools (Grasshopper) as a means of developing these structures: their pattern logic, their structural systems and their spatial expression.

The workshop investigates the structural exploitation of material performance. Materials are commonly used for their compressive strength. Traditional building structures facilitate load bearing through a correlation of compressive and tensile forces passing loads linearly through the building envelope. However, materials hold internal forces that can be incorporated into structural systems. This material performance, such as the tensile flexing of wood and steel, can be used strategically to increase structural performance thereby reducing material use and leading to a more intelligent and sustainable building practice. Whereas there is great awareness of the potentials of working with material behaviour tools there is currently little applied research into the testing of this. Today, much of the knowledge base in building practice aims to repress and control these forces. The industrial standardisation of building material uses much resource to harness the behaviours of materials. Similarly, engineering practice seeks to compute and control material performance. This project asks how these knowledge bases can be used to investigate new structural systems that incorporate material performance.

The workshop takes the interior wall as site. You are asked to develop your own spatial ambition for an interior wall probing its spatial and temporal extensions, its permeability, structure and tectonic logic. Taking point of departure in wooden structures we ask you to consider strategies for spatial transformation or differentiation and for structural and formal performance. Does your wall move over time? How can its flex be controlled to define spatial as well as structural qualities? What are the means by which you can pleat, pin, tie, steam, laminate the structure so as to articulate differentiation? The workshop introduces a series of new skills. You are asked to work between 3D modelling (rhino), parametric design (Grasshopper), speculative models (paper/wood) and full scale demonstrators (hdf). The workshop is group based. We ask you to work in groups of 4.

Schedule The workshop is short. We therefore expect you to work intensively through the week and weekend. Your tutors have planned this as part of your studies. We therefore expect you to move other appointments, work etc.
The workshop will take place in the RED HOUSE. Please bring your design tools, PCs and hand tools such as drills saws etc.
