Abstrakt

In this paper, we explore Conditional Generative Adversarial Networks (cGANs) as a new way of bridging the gap between design and analysis in contemporary architectural practice. By replacing analytical FEA modelling with cGAN predictions, we develop novel workflows that support iterative computational design and digital fabrication processes in new ways. This paper reports two case studies of increasing complexity that utilize cGANs for structural analysis.
Central to both experiments is the representation of information within the dataset the cGAN is trained on. We contribute an experimental representational technique to encode multiple layers of geometric and performative description into false colour images, which we then use to train a Pix2Pix neural network architecture on entirely digital generated datasets as a proxy for the performance of physically fabricated elements. The paper
describes the representational workflow, reports the process and results of training and their integration into the design experiments. Lastly, we identify potentials and limits of this approach within the design processes.
