Reinforced Concrete Polyhedron 1

Hello,

I have to design a polyhedron made from reinforced concrete that has an odd shape designed by the architect.
It has a standalone structure that will be cast inside an existing masonry building.
My concern is that this type of structure cannnot properly carry the loads down to the foundation slab. Because it has negative and positive angles I don't know how to splice the reinforcement.
It is also very difficult to model it in a FEM software.
Is it possible to be made this way or should I just make a vertical structure with reinforcement and the exterior shape to be made from steel frames?

Thank you.

My vote is for steel frames. Creating the formwork for something like this seems like it would be a nightmare.
 
In the past when I have had to analyze odd shaped structures, I have relied on an exterior consultant who is a 3d modelling whiz. They model the structure in a program like Rhino, mesh it, then export it in a format that I can import it into an FEA program. I have not done this with concrete, only steel plate. The shape that you have in the rendering would lend itself better to steel than concrete. I could see welded steel plate working.
 
Spending on your location, this might be an application for ferro-cement.

Thanks for the ferro-cement suggetion. I will check it out.
