Hello:

I am designing a steel sheet pile retaining wall with a 12"
concrete facing on the front face attached via shear studs. I also have a concrete shoulder/barrier shape sitting on the embankment/facing, and these are introduce axial loads and eccentricity.

What formula do you think I should use to evaluate combined bending effects?  For soldier piles I have been using AASHTO Formula 10-43 assuming that the pile is braced against buckling.  ( which is (fy/0.472Fy) + (fbx/Fbx) + (fby/Fby) < 1.0 ) Do you think this formula also applies for Sheet piles?

Thanks a lot.
