Stability of concrete deadman

[Awre]

Hello,

I utilized prosheet to quickly design an anchored sheetpile wall. The anchor load is 113 kips (12.3 kip/ft and spacing is 9.2 ft). Prosheet provides the requirment for deadman (4.5' high of the selected sheetpile section). The actual deadman is contineous concrete deadman 6' in height and 2.5' in width, placed behind the failure plane (approx. 42' behind the wall). It meets prosheet's height criteria, stiffer than typical sheetpile deadman and therefore is assumed to be acceptable. Is there any other manual calcs should be performed to check the stability of the contineous deadman?

Thanks

At 6' high, continuous, and being pulled on by a tie rod with a relatively small bearing plate; you could have bending in two directions. You said the concrete deadman is stiffer than a sheet pile deadman and "assumed" the concrete deadman is acceptable, but did you design it yet?

No it's existing- I'm oversheeting the existing bulkhead. I plan to utilize the deadman
