Further Structural Spiral Studies
Further investigations of spiral based structural strategies.
This system consists of red inner spirals that trace the core volume and blue outer spirals that trace the envelope. The black lines represent the structural members that link the 2 systems together and become the basis for the system that supports each floorplate. These radial elements take advantage of spiral intersections that relate to the floor to floor height and the rotations of the spiral. The relationship is more clear in the wireframe below.
I’ve also been exploring more playful spiral systems, in which the primary structural “spine” is no longer necessarily vertical, but rather a spiral itself (or any spline for that matter). An arbitrary volume (in this example, an ellipsoid) is mapped onto a spline as slices which are spaced at a user-specified height interval. Using similar construction techniques as above, these slices serve as the basis for creating spirals revolving about a spiral.

Ron / Nicole:
Great first pass! I appreciate the rigor of keeping the structural module in-tuned with the programmatic floor to floor heights. I think if we are to start to talk about moving to the next level, we need to maintain that rigor. I think it would be interesting to see thicknesses for the spiral diagrid structures with paying special attention to the varying thicknesses from top to bottom. For the primary structure, maybe square sections would be a good place to start; you’re looking at a 36 inch square at the base - to a 12 inch square at the very top. The secondary structure will maintain a 12 inch square base from top to bottom. You can also look at sub-dividing the glass modules on each floor in a 5 ft increments. The glass mullions will have a 4 inch thickness. I think if you are to look at some of these thicknesses, you will both start to see an architecture evolving. Can you please look at this, I will send you a elevation sketchs of some of the ideas I am referring to.
You can also look at taking the spirals forms revolving about a spiral line and assemble three or more into one configuration. With the center being the reference for the other three shapes. Try a few of these. Nicole, maybe you can help diagram some of these designs.
Look forward to seeing your next steps. Thanks
