How to size a reinforced concrete chimney/stack?

[Anonymous]

Good morning Autodesk team,

I'm actually on a project where I have to size s massive reinforced concrete stack. It is 150m high, 20m wide at the top and the bottom and its foundation in like a wind turbine. No problem to model the foundation, except support, but I don't know to model the stack. I tried with a cylinder and then apply a specific thickness on it, but It doesn't work.

After that, I would like to know how to size the whole element, can I get some reinforcements or does it work like a simple reinforced concrete element, for example a wall?

Thank you for your attention.

Regards,

Hugo W.

Please find a analogy in attachment. It's not the stack I want to model, but it shows you how it can look like.

The attached drawing is not quite clear - but it seems that it can be modeled as a shell structure.

Is my guess correct that it is a set of 5000mm diameter steel pipes packed inside load/carrying RC structure?
