Digital Form-Finding of Timber Post-formed Gridshell

Timber Gridshell in the courtyard of Naples University Federico II faculty of Architecture.
The structure is the final outcome of the Master's degree thesis:"Digital Form-Finding of Timber Post-formed Gridshell"

Authors: Andrea Fiore,Daniele Lancia
Advisors : Prof.Sergio Pone with PhD. Sofia Colabella, PhD. Bianca Parenti, Arch. Bernardino D'amico, Prof. Francesco Portioli

The main topic of the thesis is the development of a digital form-finding gridshell design tool, by a real time simulation of the material system's behavior) as well as the kinematic construction process, which consists in the bending of an initial flat grid to reach the final resistent shape.

the main factor of form finding process is structural effectiveness. we searched for the smallest value of deformation globally, for the smallest peak, for smallest strain and stress (global and local), for a minimum value of curvature, etc. The process was made in a reiterational method that permitted us to include some improvement teached us from experience in build timber-gridshells.
We also tried to optimize the form with galapagos, but our CPUs are not so fast to work in real time with kangaroo simulations.
At bottom of this process there's an architectural idea of space, based on people movement, sun shadows studies and those other things that could not be represent with numbers.

@Ben
I'm sorry, but we cannot share our definition, because as part of our master thesis, it will be published from our university.
I hope we could help you as well, so feel free to ask.

Comment by Ben Korman on August 3, 2012 at 4:22pm: Andrea,

Would you be wiling to share your grid shell definition? I am currently trying to build a definition for grid shell form finding.

Comment by djordje on July 18, 2012 at 11:19am: Thank you the reply Andrea.

So what was the main "factor" of form finding and effectiveness?

Visual, aesthetics?

Or you were trying to get construction which will have the smallest value of deformation?

Comment by Andrea Fiore on July 14, 2012 at 7:24pm: The colors represent normal deformations (and so tensional and compressional forces).
Green lines are undeformed rods (not stressed), blue lines are extended rods (tensional forces). With red line we use to represent compressed rods.

Comment by djordje on July 14, 2012 at 5:30pm: Nice !!!
Those green and blue lines that were presented in Rhino, where in fact what? Tensional and Compressional forces in wooden truss members?

Comment by Daniele Foca Lancia on July 13, 2012 at 11:47am: yeah, it's a really nice version!

Comment by David Rutten on July 13, 2012 at 11:10am: Hmm, I actually play One Note Samba on guitar but it took me a full minute to recognize it :)
