Abstract
This paper documents experimental and numerical explorations of form finding that arose from a combination of mathematical insights coupled to aesthetic considerations. Such form finding occurred through the Airy Stress Function, which has been studied previously from a purely theoretical point of view. Previously it was shown that the Airy Stress Function could be used to provide a polyhedral form diagram for problems that cannot be solved using the standard graphic statics approach. In this current study, we constructed such a polyhedron, made up of planar faces. A continuous Airy Stress Function allowed for automatic form finding, whether or not the three dimensional surface was modeled as faceted or as smoothly continuous. Another uniqueness of this current paper is that the form was also constructed at an experimentally tractable scale of 2.3m by 1.2m in plan, and 1.8m in height, using the Catalan vaulting technique of masonry construction.
