Moment of Inertia of Concrete and steel pipe wall
Moment of Inertia of Concrete and steel pipe wall
(OP)
I have a steel pipe (6" dia) soldier pile wall. The distance between the pipes are shotcreted (3" thick). What is the moment of inertia of the composite materials around the centroid axis? Is this the sum of the moments of inertia? Should E modulus taken into account? Thank you.

I think I understand why you might think there would be composite action with the pipe being embedded in the shotcrete, but the pipe does not work like a piece of reinforcing steel. The concrete will not interact with the steel pipe in the same way that concrete interacts with reinforcing steel.
