I have to evaluate the feasibility of a structure in compressed earth bricks somehow like this; base diameter about 3m and 4 to 8m tall. This might be realized in Geneva in June. As we should be able to enter it, it must be structurally safe. For now we are considering working with bricks made by http://www.terrabloc.ch/, a swiss manufacturer of compressed earth bricks.
I saw this project on-line, kind of similar although not the same material.
Do you have any idea of how to optimize the geometry in order to avoid structural buckling? Could this be made with Karamba or RhinoVault? Any idea, example or reference would be more than welcome.
