Antoni Gaudi's dynamic challenge to the straightjacket of orthodoxy

This paper considers the use of a dynamic modelling technique to 'calculate' an equilibrated structure in which performance is optimised through the computation of the forces involved using an analog technique. The example is historic- Antoni Gaudf's Colonia GUell chapel (1896-1914) - but the ideas are fresh in terms of designing the dynamic. An historical overview of Gaudf's groundbreaking project is provided as the background to a set of experiments that compare conceptual and empirical modelling, in this case specifically around the condition he set up for his Colonia GUell project. Not only do these experiments offer fresh critical insights into the wonder of one of Gaudf's more conspicuous innovations; they call into question assumptions about any reliance on analogue modelling as telling the whole 'dynamic story': there are potential conceptual gaps in such an approach. The resulting leaps of faith can probably be grounded today with greater credibility through design computation. Gaudf's innovative zeal recast against a backdrop of digital design computation demonstrates potential new approaches and directions that can be taken by today's architects and engineers.
