I didn't mean monolithic dome,  but a geodesic dome made from struts and nodes.

Dear Radu

As you know a geodesic dome is not a rigid structure  but it constantly jitterbugs around a mean.This constant tiny motion makes it a poor choice for construction with RCC system.The tiny motion slowly peals away the cement from steel rods . The structure nay not collapse but does weaken the structure.

Hubs and struts without RCC offer a much better choice.

Monolithic domes derive their strength from thin shells and not tensegrity.

My friend Peter Roberts has developed a triangular concrete block system to build geodesic domes as well as other block systems for arches. masonryarches.com

Indeed a hubs & struts structure is not rigid BECAUSE the hubs have degrees of freedom. But a cast together structure would not have the same problem.  Anyway, the leaking problem of most domes comes from exactly this rigidity problem as long as its cover is not elastic

The structure would look like this

Dear Rafi

I would not put it that way.

In a tensegrity, the compressive elements are isolated from each other and never touch each other.

They are held roughly in place by the tension chords and the system always jitterbug.

Notice no hubs and struts are mentioned in the definition!

Just increase the wall thickness of each hexagon, throw in some reinforcement wire and it will probably be okay. Lucky benefit is that each hexagon tapers in so it makes easier to extract from the mold.
