Thank you for your comments.
Yes, the H-pile section will be 50Ksi steel, with a ~17500 psi working stress max, approximately 13Kpsi at the tip assuming only the cross section. However, and as you mentioned, VAD, I have assumed a box area at the end, thus providing one square foot of area.

I am worried about axial capacity. Further research indicates little to no change in axial capacity for piles in this configuration (a long, continuous row with 3d spacing). But I feel that I am at my limit of comfort with the load we are asking the piles to carry.
A working load of 120...
Problem: 2MG Pedestal Water Tank (Steel) will be founded on a ~48 foot diameter ringwall supported by two concentric rows of driven H-piles. Piles to be driven through OC stiff clays (0-40') into very dense sands (40-50') and then end bearing on hard (N=50/2") glacial till (50-65+feet) in...
