Shoring - Section Moment of Inertia
Shoring - Section Moment of Inertia
(OP)
Could somebody help me how to calculate the moment of inertia for a composite section of steel pipe pile and shotcrete. I need to have the EI for the wall section as seen in the attached file.
For simplicity I have assumed that shotcrete thickness is one half of the pipe diameter.
I have obtained various values and wanted to check if something is going wrong.

How can I convert strll pipe pile section to equivalent concrete. If E/E' = 8 then is the equal wall thickness 8 times.

You have two separate materials not acting in a composite manner. Treat the system as a simply supported one-way concrete slab without reinforcement (your bending capacity will be very low), hopefully transferring shear to the pipes which will then be subject to bending from the slab reactions.

If you want any composite action, the shotcrete wall would have to be connected with horizontal shear studs welded to the pipe, extending into the wall, where most of the wall was at the front face of the pipe.

I mean on the compression side of the pile, the side most removed from the soil load.
