I would like some feedback for the following: When designing soldier piles with tiebacks, how should torsion be = addressed ? =20 Through conversations with other Engineer's, most ignore torsion, or = eliminate the problem be installing horizontal wales or straps to the = adjacent soldier piles. I know how to combine torsion stresses and shears (due to tieback load x = eccentricity) with normal bending stresses and shears (due to soil = loading), I just don't know how to accurately model the torsion. Is it = just a local load that transfers directly through the stiffener plates = and into the soil in bearing with no torsion about the shear center of = the soldier pile ? =20 Or does soil friction along the back side of the lean mix (slurry) = resist the torsion ?=20 I know that on many occasions (but not all), during proof loading of the = tiebacks, twisting never even occurs or is very small. So what's = resisting the torsion ? =20 =20 Ron E.
