Our group is starting to investigate how we might better control the edge seam condition of the concrete panel. We are interested in perhaps transgressing or blurring that clear modular seam, while still taking advantage of the modularity of the panel installation. This might be achieved through some kind of tessellation in 3d where the curvilinear surfaces obscure the edge. We are also interested in finding ways to reduce the material in the section.
These simulations are an attempt to get a grasp on what these investigations might mean in terms of formwork and fabric interaction.
Thinking about the seam:
- taller formwork interior than perimeter vs. shorter interior than perimeter... when aggregated, the texture is either lumpy or ridged
Thinking about how parallel planes would differently create straight edge versus bulged form as the angle of pour tilts in relation to the planes
Interest in a plane or rod interfering with the formwork from the side, on the dry side of the fabric. This side-poke could easily be made into a parametric system.
The simulation below was not satisfactory to what I had in mind... the gravity should be adjusted so that the bulging is more pronounced. Still, it's clear that more poking elements means a less dramatic bulge.
Integrating vertical and horizontal poking elements.
Looking forward, I would be interested to use some kind of stencil or milled frame through which concrete-filled fabric could bulge, and then to affect those bulges through a secondary formwork of horizontal rods or planes, essentially a two-step formwork. Slight variations in the milled frame (how large the openings are) would affect how much the concrete protruded through, and systematic changes to how far the horizontal rods poked into the interior of the formwork would then cause those protrusions to adjust. Two systems of interference to the natural gravitational pull of concrete on horizontally stretched fabric.
