Through our continued research into understanding and developing a reciprocal frame structure that can easily be deployed, a general formal logic developed. Given that reciprocal frames generally are made into dome-like configurations, our formal studies led us to a form that is based around the idea of pushing and pulling a surface to create ground connections and spatial divisions. In order to facilitate the bearing conditions created by this formal system, we began looking into funicular and spanning structures as ways to create the form.

These two systems work in different ways. Funicular systems, deriving from the Latin funiculus or “rope,” refer to the pure structural concept of a single line suspended from two points that adjust their form based on the loads being acted upon it, both in tension or compression. In contrast, spanning systems refer to the path of structural components that extend between two supports. For our purposes, we studied roof systems that extended all the way to the floor (funicular) and roof systems that spanned between two columns or walls (spanning). We also studied a hybrid of both funicular and spanning systems, in an attempt to maximize the benefits of both. While each system can be adapted to fit the overall forms we’ve been exploring, funicular and spanning systems have different implications with regard to the overall spatial experience of the pavilion.
