This week was mostly consecrated to finding a way to construct our project within the protostructure. The horizontal parts being unable to support to much weight we had to find a way to make every thing hold on the vertical beams.
The solution we found is based on a "flag system". We attach a frame to a vertical beam like a flag so it does not directly touch the horizontal beams. The whole thing being stabilised by a triangulation at the very top of the structure.
With some of the flags
Of course this system was studied trough drawings as well
