article⁄Performative Wood: Integral Computational Design for Timber Constructions (2009)
abstract⁄Wood differs from most building materials in that it is a naturally grown biological tissue. Thus wood displays significant differentiation in its material makeup and structure as compared to most industrially produced, isotropic materials. Upon closer examination wood can be described as an anisotropic natural fiber system with different material characteristics and related behavior in different directions relative to the main grain orientation. Because of its differentiated internal capillary structure wood is also hygroscopic. It absorbs and releases moisture in exchange with the environment and these fluctuations cause differential dimensional changes. In architectural history the inherent heterogeneity of wood and the related more complex material characteristics have been mainly understood as a major deficiency by the related crafts, timber industry, engineers and architects alike. This paper will present an alternative design approach and associated computational design tools that aim at understanding wood’s differentiated material make up as its major capacity rather than a deficiency. Along two design experiments the related research on an integral computational design approach towards unfolding wood’s intrinsic material characteristics and performative capacity will be discussed. The first experiment explores the anisotropic characteristics of wood by exploiting the differential bending behavior in relation to the local induction of forces through which a specific overall morphology can be achieved. The second experiment focuses on the hygroscopic property of wood as the base for developing a surface structure that responds to changes in relative humidity with no need for any additional electronic or mechanical control.
