Generative scripting and form-finding in space grid systems

This paper reports on research undertaken during preparation of a competition entry for a new roof structure at ZurichInternational Airport.Using MicroStation Generative Components and Maya dynamic scripting (MEL), the structure attempts to addresstraditional modernist concepts of openness, lightness and legibility of the flow of forces, whilst utilising parametric designto generate a randomised space frame structure. The resulting roof is presented as an architectural proposal in itsphysical context.Furthermore, the paper suggests the introduction of threshold levels and selective form finding routines within the script,which, if combined with rapid prototyping techniques for instant evaluation and mutation purposes, explore the possibilityof a widened conceptual approach towards structural design.
