Stand Up Architecture: STRUCTURAL DNA

This blog is initially set up to keep track of my process while taking a research & design course Stand Up Architecture at the Building Technology dept at TU Delft. After completing the course, I've decided to continue the project. In collaboration with Michela Turrin (PhD Researcher at TU Delft) and Peter von Buelow (Professor at Michigan University). We will work on a more extensive case study based on my findings of last quarter. We plan to publish the results in fall 2009.

Test phase 4 - Genetic Optimisation of structure

Today and yesterday i've been randomly creating generation 0 of panels (see image of screen shot below) and breeding the 1st generation based on the best ranked members of generation 0.

Peter von Buelow ( http://www-personal.umich.edu/~pvbuelow/ ) has guided me intensively during this process. The constantly adjusted parameters of the members are being generated by his Genetic Algorithm linked to a customized website (image below). The website makes it possible to download a datafile, which can be read by GC. The dxf file of the panel is then loaded in the Finite Element software STAAD-Pro, which optimizes the construction applying different sizes of steel tubes. It calculates the total weight of the structure and the ratio of structural performance. This output is uploaded to the website again, which will visualize the new best ranked members.
This optimization loop can be repeated untill the results approach an optimum according to the previously defined criteria.
