90 degree inside corner soldier pile configuration 1

[gre2408]

I want to know in normal practice how other engineers configure inside and outside corner piles requiring anchors? For outside corner pile, in order to eliminate use of anchors for the pile I normally use a number of straps using 4x1/2 steel bar welded on flanges of adjacent h-piles each direction. In this case, the straps will work as a tension member like anchors and I also check bending of h-pile section in weak axis. Do you have any idea for inside corner pile? I may use a small tube section as a compressive member though, want to see if there is any better way to do it. Thanks!

You can do that or create a "box" by placing a diagonal that cuts across the corner attaching soldier pile to soldier pile (try and keep a 45 degree angle), and add tube between piles (form a horizontal truss essentially). Be careful of unbalanced loads at the corners. This of course requires blockouts in the structural wall. For the straps, I typically like to use an HSS section on the inside flange with similar dimensions to the lagging so the contractor can just lay it like lagging (requires only two cuts, like a plate, unlike an Lx which requires cuts and copes.)
