sheet pile wall axial loads
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.
you can refer to the pile design manual by corus.this is available in their website.
